If we need to burn off an area the size of Maine, the Mill Valleys are expendable

 


A bit more background on one of reasons the New York Times housing article we've been discussing made me so angry (though in fairness, it is actually a significant improvement over what we've been seeing from the NYT on the subject).

Western mega-fires fall into that distressingly familiar category of dire crises with obvious solutions that people have alarmingly little interest in fixing. There is no real disagreement over what needs to be done (there hasn't been for decades), but the magnitude is stunning. [emphasis added]


Yes, there’s been talk across the U.S. Forest Service and California state agencies about doing more prescribed burns [a.k.a. controlled burns -- MP] and managed burns. The point of that “good fire” would be to create a black-and-green checkerboard across the state. The black burned parcels would then provide a series of dampers and dead ends to keep the fire intensity lower when flames spark in hot, dry conditions, as they did this past week. But we’ve had far too little “good fire,” as the Cassandras call it. Too little purposeful, healthy fire. Too few acres intentionally burned or corralled by certified “burn bosses” (yes, that’s the official term in the California Resources Code) to keep communities safe in weeks like this.

Academics believe that between 4.4 million and 11.8 million acres burned each year in prehistoric California. Between 1982 and 1998, California’s agency land managers burned, on average, about 30,000 acres a year. Between 1999 and 2017, that number dropped to an annual 13,000 acres. The state passed a few new laws in 2018 designed to facilitate more intentional burning. But few are optimistic this, alone, will lead to significant change. We live with a deathly backlog. In February 2020, Nature Sustainability published this terrifying conclusion: California would need to burn 20 million acres — an area about the size of Maine — to restabilize in terms of fire.

...

[Deputy fire chief of Yosemite National Park Mike] Beasley earned what he called his “red card,” or wildland firefighter qualification, in 1984. To him, California, today, resembles a rookie pyro Armageddon, its scorched battlefields studded with soldiers wielding fancy tools, executing foolhardy strategy. “Put the wet stuff on the red stuff,” Beasley summed up his assessment of the plan of attack by Cal Fire, the state’s behemoth “emergency response and resource protection” agency. Instead, Beasley believes, fire professionals should be considering ecology and picking their fights: letting fires that pose little risk burn through the stockpiles of fuels. Yet that’s not the mission. “They put fires out, full stop, end of story,” Beasley said of Cal Fire. “They like to keep it clean that way.”


Why is it so difficult to do the smart thing? People get in the way. From Marketplace.

Molly Wood: You spoke with all these experts who have been advocating for good fire for prescribed burns for decades. And nobody disagrees, right? You found that there is no scientific disagreement that this is the way to prevent megafires. So how come it never happens?

Elizabeth Weil: You know, that’s a really good question. I talked to a lot of scientists who have been talking about this, as you said, literally, for decades, and it’s been really painful to watch the West burn. It hasn’t been happening because people don’t like smoke. It hasn’t been happening, because of very well-intended environmental regulations like the Clean Air Act that make it harder to put particulate matter in the air from man-made causes. It hasn’t happened because of where we live. You don’t want to burn down people’s houses, obviously.

 

For better than a hundred years, we’ve been setting too few fires and putting out too many. It wasn’t always like this. The indigenous tribes mastered fire as a forest management tool and used it extensively until the European settlers criminalized the practice, thus setting us up for the disaster facing us today.

The result has been a tinder bundle the size of Maine. Clearing it out is California’s second most serious environmental challenge (after global warming) and is the most urgent problem we face, period. Solving it requires a level of focus and political will that our current governor simply does not have (particularly compared to his predecessor). It’s up to the rest of us to keep this top of mind.

There are huge externalities to these projects, almost none of which can be easily addressed though a conventional regulatory framework. I would need to reach out to experts to be sure, but I doubt environmental impact laws even apply here since we aren’t worried about the direct damage the developments cause to the forests; we’re worried about the damage we’ll cause to the forests trying to protect those developments.

Every dwelling an a forest-adjacent wildland urban interface has got to be treated as, to some degree, expendable, or at the very least, the people who live there need to accept that they are on their own. When frequent controlled burns fill their neighborhoods with smoke, they shouldn't be able to file complaints. When those fires become uncontrolled (as they sometimes inevitably do), they should not have the option of suing.


 

 It would be different if these upscale forested developments had any real possibility of having a substantial impact on the housing crisis, but we're talking about badly situated and trivially small pieces of land in the third largest state in the country. They arguably cause more problems than they solve and the disproportionate focus on them distracts us from a situation where we cannot afford distraction.

Twelve years ago at the blog: multiply all dollar amounts by 1.5

Wednesday, June 16, 2010

When is a dollar not worth a dollar?

Joseph and I have been putting up a number of post on compensation recently (many inspired directly or indirectly by Felix Salmon), but there is something important that's been left out of the discussion both here and on the other blogs I've been reading on the subject:

Some dollars are worth more than others.

Having bounced back and forth from statistician to teacher to entrepreneur over the years, I've seen plenty of large fluctuations in income and I've developed a pretty good idea of what it costs to live comfortably as a single person in various cities.

In LA the cutoff is somewhere around thirty thousand. For that money you can get a decent apartment in pleasant neighborhood and still have enough income left over both to meet your basic needs and to get out and have some fun. (LA is one of the world's great cheap-eats towns)

If you go from mid-thirties to mid-nineties (which I did at one point), you will see a significant change in your lifestyle but it is nothing compared to the change you'll feel if you go from the mid thirties to the low twenties. Below thirty you start facing some ugly compromises. You may have to move to a rough part of town, Food becomes a larger part of your budget. Costs associated with work (wardrobe, transportation) remain annoyingly constant. Going out with friends becomes a great luxury (it's hard to convince the bartender to sell you two-thirds of a beer)

This discrepancy in lifestyle suggests the need for a different metric. Here's an example. To make the numbers come out even, let's talk about three incomes: 21K, 30K, 90K with our hypothetical Angeleno starting in the middle. In both absolute (60K) and relative terms (200%) the jump to the top tier dwarfs the jump to the bottom (9K/30%) but in impact on quality of life, the exact opposite holds.

What does all this mean? For one thing, it means that expected value and marginal changes are not the right tools to look at compensation, at least not in the way we normally use them. It means that the problem requires more of a piecewise approach.

Money rules for the rich

This is Joseph

One of the things that often makes me crazy is personal finance advice. Don't get me wrong, there is good personal finance advice out there. But it can often fall into one of several genres that end up not really being helpful to the median reader. One example is the "buy fewer lattes", which does get at a good point (small expenses can add up) but doesn't move the needle much for large financial challenges. 

The other is the advice that is very useful if and only if you already have a lot of money. This article was a good example of this genre. Was the advice good? You bet. Was any of it usable at my income level and life stage. No, not really. 

For example, consider these items of advice:
3. Strive to own your home, not rent — and try to buy in cash. This is particularly the case if you’re a moderate to high earner. Having more of your money packed in your home is a way to shelter it from federal and state asset-income taxation.

4. Mortgages are tax and financial losers. Pay them off ASAP. Think about it: If you have $100,000 that you can invest right now in a bond earning 1.5%, you’d have $1,500 in interest income over the course of a year. But if you had a $100,000 debt at a 3.2% interest that you could pay off right now, you’d save $3,200 over the course of the year in interest payments.

On balance, you’d make $1,700 with no risk by investing in debt repayment rather than investing in the bond.

Buying a home in cash is a formidable problem with income. The median house price in Chicago is $329,000.  Boston is more like $740,000. Cheaper prices might exist elsewhere but nowhere is this an inexpensive prospect. Median household income in Chicago is $62K. Saving 10% of pre-tax income would require about 50 years to save this much or about 40 years with a 1% post-tax and inflation-adjusted return. That's not bad for a stable investment (10 year TIPS bonds are under 0.3% at the moment and that is pre-tax). A long run stock market average is about 7% (so maybe 5% post-tax) and that'd work out after about 25 years. 

But the real assumption is that you have $300,000 or so in assets that you can chose how to allocate, in a way that does not cause liquidity problems. 

6. Your perfect home may be far cheaper several time zones away. Or it may be someplace with no state income tax, no state estate tax, and no state inheritance tax.

Moving is expensive. Not having a support network is expensive. International moves, in particular, can be quite challenging. 

16. Wait until age 70 to take Social Security retirement benefits. Retirees who wait to claim can get hundreds of dollars more each month than those who take benefits early.

Of course, this isn’t feasible for everyone. But here’s my plea: Before making any moves, figure out the strategy that maximizes your household’s total lifetime benefits.

This is good advice but it presumes that people are able to work until 70 or bridge the gap with savings. Maybe a good goal, but much more feasible for an economist than a roofer. 

But the one that I found the most worrying:

1. Don’t borrow for college. It’s far too risky and expensive. I don’t say this lightly. I’m a college professor. But you can get a fine education without mortgaging your future and potentially dashing your career plans.

It simply involves pursuing scholarships and applying to less expensive, if generally less prestigious, institutions. 

Even in Canada, which has cheaper education, one in two students graduates with debt. This is not simply a case of look for a cheaper school (in Canada there are not the large prices or price variations of the US) and it is unclear that there are that many scholarships lying around. Education is an earnings multiplier and a professional degree (e.g., Nursing) could open the doors to much better employment opportunities. The wage premium for a University degree in Canada is 53% or $13/hour. The median debt is about $20,000. Even post-tax that is 2-3 years of income to compensate.

Now don't go into huge amounts of debt -- yes, that is a good idea. The author is at Boston University and went to Harvard -- there are students in those schools who could well follow the advice to minimize student debt. But it is also the case that debt can be a form of investment in human capital and, done wisely, may well pay off.

Anyway, the big take-away is that financial advice is very context dependent. A lot of this advice is very good for upper-middle class to wealthy Americans who have assets and can afford to think about wealth management. But it really doesn't seem to be the points that the median family is going to be able to easily apply.

"The joy of the bezzle" -- Crypto, meme stocks, housing bubbles and inflation

People spend money based, not on how much money they have, but on how much money they think they have. Often that's a distinction without a difference, but in a time of scams and bubbles, the gap can be big enough that we need to start figuring it into the way we think about the economy.

Which brings us to John Kenneth Galbraith's bezzle.

From the Great Crash 1929:

Alone among the various forms of larceny [embezzlement] has a time parameter. Weeks, months or years may elapse between the commission of the crime and its discovery. (This is a period, incidentally, when the embezzler has his gain and the man who has been embezzled, oddly enough, feels no loss. There is a net increase in psychic wealth.) At any given time there exists an inventory of undiscovered embezzlement in—or more precisely not in—the country’s business and banks.

...

This inventory—it should perhaps be called the bezzle—amounts at any moment to many millions of dollars. It also varies in size with the business cycle. In good times, people are relaxed, trusting, and money is plentiful. But even though money is plentiful, there are always many people who need more. Under these circumstances, the rate of embezzlement grows, the rate of discovery falls off, and the bezzle increases rapidly. In depression, all this is reversed. Money is watched with a narrow, suspicious eye. The man who handles it is assumed to be dishonest until he proves himself otherwise. Audits are penetrating and meticulous. Commercial morality is enormously improved. The bezzle shrinks.


From the Bezzle Years by John Kay

In a delightful essay, Warren Buffett’s business partner, Charlie Munger, pointed out that the concept can be extended much more widely. This psychic wealth can be created without illegality: mistake or self-delusion is enough. Munger coined the term “febezzle,” or “functionally equivalent bezzle,” to describe the wealth that exists in the interval between the creation and the destruction of the illusion.

From this perspective, the critic who exposes a fake Rembrandt does the world no favor: The owner of the picture suffers a loss, as perhaps do potential viewers, and the owners of genuine Rembrandts gain little. The finance sector did not look kindly on those who pointed out that the New Economy bubble of the late 1990s, or the credit expansion that preceded the 2008 global financial crisis, had created a large febezzle.

...


The joy of the bezzle is that two people – each ignorant of the other’s existence and role – can enjoy the same wealth. The champagne that Enron’s Jeff Skilling drank when the US Securities and Exchange Commission allowed him to mark long-term energy contracts to market was paid for by the company’s shareholders and creditors, but they would not know that until ten years later. Households in US cities received mortgages in 2006 that they could never hope to repay, while taxpayers never dreamed that they would be called on to bail out the lenders. Shareholders in banks could not have understood that the dividends they received before 2007 were actually money that they had borrowed from themselves.


Kay wrote that essay in 2015, a period which seem insane at the time (where could you go after MoviePass?) If only we had known that the "lose money on every transaction then make it up in volume" model would be pushed aside by something crazier and of far greater magnitude.

In 2021, the bezzle grew to unimaginable proportions. Imagine a well-to-do family sitting down to calculate their net worth last December. Their house is worth three times what they paid for it. The portfolio's doing great, particularly those innovation and disruption stocks they heard about on CNBC. And that investment they made in crypto just for fun has turned into some real money.

Now think about this in terms of stimulus. Crypto alone has pumped trillions of dollars of imaginary money into the economy. Analogously, ending the bezzle functions like a massive contractionary tax. Markets returning to rationality is seen as taking away money from investors. [Emphasis added.]

New CEO Barry McCarthy took the helm in February and has vowed to turn around the company, which had been thriving during pandemic lockdowns but is now struggling with slowing demand. But he has dismissed the idea of selling the business—irking investors like Blackwells, which says that Amazon.com Inc. and others could be bidders.

Peloton co-founder John Foley was removed from the CEO job in February’s shake-up, but remains executive chairman and is part of a group that controls the company with super-voting stock. That limits the power of an investor like Blackwells to force Peloton’s hand.

...

“No shareholder should want Mr. Foley to still sit atop the management pyramid or control the board through his super voting-stock. He lost his entitlement to both positions when he destroyed $40 billion of shareholder wealth in less than a year.”

In response, Peloton said it “appreciates the views of our shareholders and have acted, and will continue to act, in the best interests of all Peloton shareholders.”

McCarthy, a former finance executive at Netflix Inc. and Spotify Technology SA, has been working to boost Peloton’s revenue from services -- as opposed to hardware.


Of course, that $40 billion of shareholder was no more destroyed than the value of a diamond is destroyed when the appraiser reveals that it's paste. The difference between Peloton trading at 160 and at 10 was pure febezzle.



Of course, economic contraction is always painful, but at the moment it's not the worst imaginable outcome.

I suspect Marshall was joking but he might not have been entirely wrong.

Just over five years ago at the blog: “I’m almost afraid not to take the chance,” – This is when it becomes a bubble.

I went through all of our crypto posts and this quote (along with the story around it) jumped out at me. It captures that key shift when the madness really kicks in. 

Just to be clear, there was already a bubble before we ran this, but 2017/2018 was around the time the state of things became obvious. ("When the bubble became obvious" would be a more accurate but clumsier title.) Anyone who was still talking about the promise of cryptocurrencies in 2019 is someone whose financial advice should be avoided in the future.

The article also does  good job of reminding us of the human cost. Recently, much of the public face of web3 has been dominated by truly noxious (and often misogynistic) flakes and assholes waving away inconvenient facts with hfsp ("Have fun staying poor"). Most people getting hurt committed no crime other than to believe the hype which, up until a few months ago, most of the press was also buying into.

“I’m almost afraid not to take the chance,” – This is when it becomes a bubble.


It's that moment when risk aversion flips and the thought of not making money starts to feel like losing it. I'm not talking about opportunity costs in any kind of rational sense. Instead, I'm referring to having the visceral emotional reaction associated with a deep, costly loss because you didn't buy into the skyrocketing market the day before. People become afraid not to invest in what should obviously be highly risky ventures.

Truly crazy bubbles are driven by this paradoxical combination of greed and fear. They both desire instant wealth and dread the sense of regret that would go with missing it. Individually, either of these emotions can drive otherwise sensible people into irrational behavior. Together, they can spur investment in some laughably bad ideas.

This Washington Post piece by Chico Harlan on a group of Bitcoin investors perfectly illustrates the point.

“Us little guys working our butts off, we can’t get ahead,” Cedric Knight, 35, told Melin. “This is a once-in-a-lifetime opportunity to change my life.”

Knight and others visiting Melin were pinning their hopes on a new form of currency whose potential value the world was only beginning to recognize. Millions of people around the world are chasing after fortune by investing in bitcoin — which has soared by more than 2,500 percent in value in the past two years — and other digital instruments known as cryptocurrencies.

...

“What crypto allows is for the masses to be venture capitalists,” Melin said.

“And guys like me, I’m not in the loop,” Knight said. “This is my chance.”



Knight, meantime, went home, cooked dinner and then decided to reopen one of the eight cryptocurrency apps he had downloaded. His account had fallen nearly $500 on the day — his initial $1,500 was below $900 — and he said he was “freaking out.” But then, he thought about what it meant to be a cryptocurrency investor. There would be days such as this. But there might be better days, too — much better days. If there were, he did not want to miss out.

“I’m almost afraid not to take the chance,” he said, and soon, he added $260 to his cryptocurrency account.



Some historical perspective from the archives.

"A company for carrying on an undertaking of great advantage, but nobody to know what it is."

Another except from Charles Mackay's  Extraordinary Popular Delusions and the Madness of Crowds. I believe "a company for carrying on an undertaking of great advantage, but nobody to know what it is" was an initial business plan for Groupon.


Some of these schemes were plausible enough, and, had they been undertaken at a time when the public mind was unexcited, might have been pursued with advantage to all concerned. But they were established merely with the view of raising the shares in the market. The projectors took the first opportunity of a rise to sell out, and next morning the scheme was at an end. Maitland, in his History of London, gravely informs us, that one of the projects which received great encouragement, was for the establishment of a company "to make deal-boards out of saw-dust." This is, no doubt, intended as a joke; but there is abundance of evidence to show that dozens of schemes hardly a whir more reasonable, lived their little day, ruining hundreds ere they fell. One of them was for a wheel for perpetual motion—capital, one million; another was "for encouraging the breed of horses in England, and improving of glebe and church lands, and repairing and rebuilding parsonage and vicarage houses." Why the clergy, who were so mainly interested in the latter clause, should have taken so much interest in the first, is only to be explained on the supposition that the scheme was projected by a knot of the foxhunting parsons, once so common in England. The shares of this company were rapidly subscribed for. But the most absurd and preposterous of all, and which showed, more completely than any other, the utter madness of the people, was one, started by an unknown adventurer, entitled "company for carrying on an undertaking of great advantage, but nobody to know what it is." Were not the fact stated by scores of credible witnesses, it would be impossible to believe that any person could have been duped by such a project. The man of genius who essayed this bold and successful inroad upon public credulity, merely stated in his prospectus that the required capital was half a million, in five thousand shares of 100 pounds each, deposit 2 pounds per share. Each subscriber, paying his deposit, would be entitled to 100 pounds per annum per share. How this immense profit was to be obtained, he did not condescend to inform them at that time, but promised, that in a month full particulars should be duly announced, and a call made for the remaining 98 pounds of the subscription. Next morning, at nine o'clock, this great man opened an office in Cornhill. Crowds of people beset his door, and when he shut up at three o'clock, he found that no less than one thousand shares had been subscribed for, and the deposits paid. He was thus, in five hours, the winner of 2,000 pounds. He was philosopher enough to be contented with his venture, and set off the same evening for the Continent. He was never heard of again

Bitcoin and transaction costs

This is Joseph.

Mark has noted that he called the cryptocurrency bubble in advance [which makes me sound a bit dickish when you just come out and say it -- MP]. We are all aware that Bitcoin is volatile, which is a bad property as a store of value. But other stores of value are also volatile (like gold). But one feature of bitcoin seems under-reported. We know that miner rewards drop with time and that about 20% of bitcoin is "lost". The lost feature is terrible because it means the supply shrinks with time to become less and less -- in other words the currency is naturally deflationary. Deflationary is bad because it encourages holding on to money instead of spending money, which is not a good economic feature. Again, all well know issues. 

We also know about the slow transaction speed (visa does 1,700 transactions per second, Bitcoin does 4.6) which creates concern about scalability and ability to settle small transactions quickly. 

But what about transaction fees. Here is Square's transaction fees in Canada:
Square has competitive, transparent pricing so you know exactly how much you’re paying to process credit and debit cards. It’s just 2.65% per tap, dip or swipe for Visa, Mastercard, American Express and international credit cards, 3.4% + 15 cents for each card not present transaction (like Virtual Terminal), and 2.9% + 30 cents for other transactions (like invoices paid online). For debit transaction, it’s just a 10 cent flat fee for every Interac insert and tap.

Now a currency, like Bitcoin, is probably closest to Interac.  So that is about 7.9 cents in USD. What are the transaction fees like with Bitcoin? Well, they are not fixed but it is a bidding process. Looking at the past year or so we have fees like: 

  • June 13th USD$2.492 
  • June 12th USD$1.258
  • March 2nd USD$4.471

The lowest of these would be 16 times the Interac rate and would pull level with VISA at nearly the USD$100 mark. Keep in mind this is while rewards for miners are still happening so prices could still go up. 

On April 19, 2021, it reached a peak of USD58.858. 

Now consider an Interac transaction for a cup of coffee. The best coffee is starbucks [That's the only factual error in this post -- MP] and it costs $2.10 plus 13% HST tax for a cup in Ontario (specific locations may vary). An Interac card leaves the store with $2.00 revenue for the cup. Visa leaves the store with $2.04. So a profitable transaction. Now interac is currently running 7 transaction per second but it is in only one small country (Canada) with 40 million inhabitants. Bitcoin is traded worldwide. 

With a bitcoin the cost on June 13th would be about CAD$3.19 for a net loss. If the customer pays the fee then the cost of a cup of coffee, after tax, goes from $2.37 to $5.56 if you pay the average transaction fee. Paying low transaction fees may make the processing unattractive. 

How long does this take on average at the storefront with all going well? Estimates of about 10 minutes are not reassuring for a coffee shop. Small interac transfers are very fast compared to that (I find the actual interface takes 10-15 seconds to confirm). 

Other currencies don't seem to be a solution. Ethereum was USD$2.182 on June 13th, 2022 which isn't a huge advantage over bitcoin. Nor does the 30 transaction per second compare favorably to VISA. Proof of stake is interesting but one might want to wait a bit and make sure it was not vulnerable to clever coders or investors, as coding errors have caused a hard fork before

Now, keep in mind the use case of Bitcoin is as a currency and not an investment. The idea is to get in early before everyone uses it, which essentially requires it to be deflationary to make a buy and hold strategy rational. So you have a slow, expensive technology that can't solve the basic problems that paper currency can? But it is both deflationary, volatile, and hard to estimate transaction costs on. 

Are these good properties?

Journal Club: when the headline and findings diverge

This is Joseph.

This study has been making the rounds:


Now I want to be very careful here. What was the actual category (listed as #2 in the article:
The datasets are available from the corresponding author on reasonable request.

Now look at what happens:

In summary, of 1792 e-mails sent, we did not receive any response for 1538 articles because messages were not delivered (N=77; 4.3%) or the author did not reply (N=1461; 81%). Responses were received from 254 (14%) contacted authors 

So, first of all, I am not sure that we should consider the 4% who did not have a message delivered considered to be "non-compliant". That is important as the headline number of  93% did not respond includes those who were not actually successfully contacted. Of those responding, about 1/2 (122 vs 132) shared their data. 

Then we have the most common reasons:

  1. The authors asked for more information about our study, but after our detailed response and clarification, we did not receive further response from them 
  2. Their informed patient consent did not include sharing data with other researchers, or the ethical committee prohibited external data sharing and use 
  3. They cannot access the data, either because they are no longer in the institution that conducted the research, or they are no longer active on the project 
  4. They do not want to share the data or in any way participate in our study without a specific explanation
Some of these are declining to be in the study and some seem like reasonable excuses. Data often belongs to the institution and a closed down lab might have no way to get data. Still, of the responders the success rate was 48%, which seems like a reasonable level of outcome given that you are openly declaring that this is for a study and not for the research project itself.

That reminds me, what about the non-responders:
The Ethics Committee of the University of Split School of Medicine approved the study protocol. Scanned approval of the Ethics Committee was available to the study participants on request. Study participants were informed in the invitation that their response to the emailed questions is considered as their written informed consent.
So, responding to the email is considered to be consenting to the study. Which means that people who decided not to participate are being told that sending a response is considered written and informed consent. Now the sample letter they used is not yet available online, but is participating in a study mandatory

So what does Canada think about this
. . . the core ethics principle of respect for persons implies that individuals who participate in research should do so voluntarily, understanding the purpose of the research, and its risks and potential benefits, as fully as reasonably possible
What about the US NIH:

Informed Consent

The Belmont principle of respect for persons is primarily applied by requiring that all human
subjects research participants provide voluntary informed consent to participate in research.
The three fundamental aspects of informed consent are:
1. Voluntariness
2. Comprehension
3. Disclosure

And:

Potential participants must understand that enrolling in the research is voluntary and that they may withdraw from the study at any time without penalty or loss of benefits

So there are two reasons that a person could chose not to have provided data:

  1. They were not being especially honest in providing data
  2. They chose not to consent to a research study
What do the authors conclude:

In conclusion, authors of research articles are frequently not willing to share their data, even if they wrote in their manuscript DAS that they would do so. Our findings can enable the creation of new guidelines and practices in the research community to foster the availability of raw research data

It is worth also noting that they are not making the raw data available for this study, which doesn't seem to foster the availability of raw data.

We did not publish our raw data along with the manuscript because it could be understood that we are publicly shaming authors who did not want to share their data. As for the raw data that were received during this study, we informed our study participants that those raw data will be deleted after being examined and that all data and communication will be treated with strict confidence

 But putting that aside, they really can't tell the difference between choosing not to participate and declining to share data.  But they had a 48% success rate among the responders and even that denominator is shaky.

Consider items 1 and 4 of the most common reasons. How different is that from withdrawing consent from the study based on being informed? Reason #3 (lost access) seems like a pretty odd thing to frame as "not compliant" (the author's title). Reason #2 is odd but could be an issue for sharing data outside of the context of replication or exploration (what is reasonable is a very important nuance).

So all we could be discovering is that busy researchers often decline to participate in mass email research studies that involve a fair amount of labor (in this case uncompensated). Among those who had the ability to respond, I think they got better than half as reasons like the ones below may not really make sense to include in the denominator:

  • A conceptual article, no data to share
  • The author wanted ethics approval translated into English
  • They cannot access the data, either because they are no longer in the institution that conducted the research, or they are no longer active on the project
  • The corresponding author instructed us to use a web service to request the data
Is it "not compliant" if the author lost access to the data (institution being especially clear) or they wanted a web service to be used? What is really missing here is a clear statement of the estimand, which is the propensity to participate in an email study and not the propensity to share data with peers. 

In any case, this is a long discussion of an article. But the headline is getting a lot of engagement and I am not sure it can be clearly interpreted that way. A data request, as a part of research, becomes voluntary based on clear ethical principles and it seems very odd to characterize a decision not to engage as "not compliant" when you state even replying to the email is taken as informed consent. Nobody is entitled to informed consent (it's consent not obligation) and so it is utterly unclear what the rate would be in the 85% who either never got the email or chose not to consent to a voluntary research study.

Simple political analysis

This is Joseph.

As a fun palate cleanser after Mark's extremely important post, I thought that discussing this tweet would be fun. But seriously, watch the video first. 


Changing a sitting president is challenging, even if the incumbent is willing to step aside. Just for the record, there is no hint that Joe Biden is interested in stepping aside. That said, if he did, these seem to be his political weak points:
  1. Age (he will be 83 when he starts a second term). I actually think this might be his biggest vulnerability if the Republicans run somebody younger (e.g., not Trump)
  2. Inflation is always politically painful
  3. Other branches of government (primarily the judiciary but also things like the filibuster threshold in the senate).
Bernie helps with none of these. He is a year older then Biden and Biden would be starting a second term and not a first. At the end of two terms, Bernie would be over 90. Biden is well aware inflation is bad and that constrains populist plans (with inflation and interest rates rising, you need to make more serious tradeoffs which makes it hard to get a major spending program going). 

What about the courts? The Trump speed run on the judiciary is real but it isn't like Biden isn't addressing it. Despite a very narrow senate majority, he even confirmed a very competent supreme court justice with a history as a public defender. The senate is a concern as it has a skew that makes it favorable for Republicans. But I am unaware of any case where Bernie running would assist greatly with the senate races. But really that'd be the only scenario that would be at all intriguing.

Speaking of the senate, Bernie is 80 years old and will be 83 at the start of a 4th senate term in a state with a Republican governor. If we are worried about the senate then getting a strong replacement in the next two years seems far more productive.

Now, I am on record as saying it would not surprise me if Joe Biden was a single term president. He returned to political life at a time that really required somebody of his talents and background, but he is also nearly 80. Nor is this without precedent:  Lyndon B. Johnson, James K. Polk, James Buchanan and Rutherford B. Hayes were all voluntarily one term presidents (and Hayes was succeeded by another Republican so party switching is hardly a certain outcome in this small sample). 

But a replacement needs to a tell a compelling story about how they would improve the fortunes of the Democratic party. Bernie has been extremely important in setting policy priorities and will end as an extremely important senator. But he addresses none of the three main vulnerabilities and I think it is hard to see who could impact #2 and #3. So you need somebody with Joe Biden's strengths but who is less susceptible to the "sleepy Joe Biden" line of attack. But keep in mind this was not a highly successful line of attack. So options are quite limited. 

But that depends on a great many tough political decisions and a lot of things that are unknowable (e.g., what Joe Biden wants). But I see no good argument. Even Trump running again doesn't move the needle -- Biden already beat Trump and that'd be compelling psychology in a rematch.

"Legitimate Political Discourse"

Thursday, June 9, 2022

Arguments not in evidence

This is Joseph.

Mark had a pretty strong reaction to my last piece. It has been a while since we had a debate and I think this is a good place for one. Let me state, before anything else, that Mark made good points. 

But here is the thing, even though the reasons that he brings up are absolutely correct, they are not actually part of the core arguments being made by either side. I see the issue is administrative processes dragging on for very long periods of time, I think that whole new reasons becoming clear, as the megafire issue because more obvious, is actually a good example of this phenomenon. 

The environmental impact report does mention the wildland fire risk as follows:

Wildland Fires

The Project site is located in a mostly urbanized area, and is surrounded by a variety of residential and commercial/office land uses. While the majority of the surrounding area is currently developed with residential and commercial uses, uphill to the north of the Project site is an additional a roughly 4.6 acres of undeveloped privately-owned parcel land, itself surrounded by development. This relatively small and isolated wild area would not be considered a high risk for wildfires and is not in an identified high fire hazard zone, as listed in Section 5.3.1 of the General Plan. In addition, it the Project is subject to approval of the Fire Marshal as it relates to brush and vegetation removal to the north. As such, the Project would have a less than significant impact.

Now this report is from 2012; conditions may well have changed. But this is a decade ago. The real concern here is not that the development is or is not approved. It's that starting a process to determine whether it can be approved or not is still going nearly 18 years after the initial process began.  

Perhaps my first piece could have been clearer: it would be a far better world where the project was just dead after 5 years than one in which the costs can be driven up so much by legalistic delay. If the project is a bad idea then it should be canned. But it has been a decade since the final environmental report. Maybe it was botched. Maybe we know more a decade later. 

It's also worth noting the original zoning that is being challenged (i.e., what could be built without the zoning change): Professional Administrative Office. So this debate is not about protected wildland but a debate about whether this parcel of land should be a series of townhomes or an office building. Now maybe it should be protected wildland, but the process should be a lot faster, one would think, about making this determination. 

But the petition itself makes none of the excellent arguments that Mark is making (go read them first, they are smart and well taken, unlike what you are about to read):

The project as proposed would result in unacceptable adverse impacts on public safety and traffic congestion due to the increased number of vehicles attempting ingress and egress onto East Blithedale, at what is already the City’s most congested intersection.

The project proposes height, unit density, and building massing that is grossly inappropriate and out of character with the surrounding neighborhoods and structures, which would result in significant adverse visual and aesthetic impacts to those neighborhoods, and be in direct violation of the City's Design Guidelines and General Plan policies for the area.

The conclusions of the EIR that the project will have no significant impacts which cannot be mitigated, particularly with regard to traffic and visual criteria, are unrealistic and without basis in fact.

The project’s density would result in the complete loss of valuable open space, the obliteration of vegetation on the final foothill of Mt. Tam, and a loss of the aesthetic quality of the natural entry to Mill Valley.

The actual arguments are 1) traffic, 2) doesn't look nice, 3) we don't agree with the EIR's disagreement with #1 and #2, and 4) "valuable open space would be lost", which is a value to current homeowners more than anyone else. 

I would have far, far more sympathy with the arguments if they had something like "California megafires are already making this area too dense and it would be unsafe to increase density; we need to build elsewhere". But the arguments being made are what they are and the smart arguments seem to be absent. 

Perhaps this example is unrepresentative of the broader housing conversation in California. First, it is amazing how atypical San Francisco issues often are of broader CA issues. How many people would guess that the LA metro area much, much larger than SF metro area in population? Second, it would hardly be surprising for the NYT to pick the least relevant part of a problem in California. Some would say that it might actually be typical. 

But I don't see how this type of slow process is helpful to quality and thoughtful development, given the arguments being advanced. I am really unclear why the office building would improve neighborhood character as opposed to the townhouses. Or how it makes sense to block any development of somebody else's land when it was clearly zoned for development  when purchased. Maybe this is a rare and exceptional SF area problem that doesn't leak into other areas of California. 

But it is clear that housing costs are growing. Fresno has nearly doubled in cost in the past 5 years (from a bit over $200K to a bit under $400K). I think it makes sense to consider the reasons. That said, I must admit that low interest rates are absolutely for sure a bigger driver than zoning disputes.

California has a serious shortage of housing but apparently it's nothing like the New York Times shortage of straw men

 Joseph may just be trolling me here:

The recent New York Times article on the twilight of the NIMBY was interesting just for the low level of actual good ideas for why new housing is bad. The idea was to build 20 condos on a hill in a neighborhood of detached houses. 

 

While arguments given here certainly do qualify as "low-level", it's just possible that this has less to do with the quality of the potential reasons not to build this particular structure and more to do with the fact that the New York Times has gone all-in for the narrative that blames the housing crisis on hypocritical liberals in expensive neighborhoods, and we know from experience that when this paper invests in a narrative, the staff will do anything to protect that narrative up to and including sacrificing their first born.


In this case, Kirsch may be illogical, hypocritical, and selfish, but she is not wrong. It actually is a horrible idea to put more development in Mill Valley.

To understand why we don't want more people here and why Conor Dougherty's article can't be taken seriously, we need to start with wildland–urban interfaces (WUIs) "a zone of transition between wilderness (unoccupied land) and land developed by human activity – an area where a built environment meets or intermingles with a natural environment. Human settlements in the WUI are at a greater risk of catastrophic wildfire."

 As you can see, Mill Valley construction is problematic from a WUI standpoint.


Nor is history reassuring:
 

On July 2, 1929, a fire lookout on Mount Tamalpais spotted smoke rising from the railroad grade on the eastern slope. A wildfire, cause unknown to this day, had sparked on the mountain, flames blowing downhill toward Mill Valley below. Though the Great Mill Valley Fire covered a relatively small footprint, it was disproportionately destructive, burning for three days and incinerating more than 100 homes.

Sixteen years later, in September 1945, another major fire stormed through the Mount Tamalpais watershed. Dry weather and strong winds converted a pair of small brush fires into an inferno that burned more than 20,000 acres, from Lagunitas to the Bolinas Lagoon. While there hasn’t been a major fire on Mount Tam in the 74 years since, between 1881 and 1945 the area burned five times.

“Everyone thinks about that,” says Shaun Horne, Natural Resources Program Manager for the Marin Municipal Water District. Without a significant fire in decades, he says, and with the encroachment of invasive plant species, “There’s more potential fuel. It’s a high-hazard environment for wildfire.”


 

Encouraging development in WUIs is generally a bad idea for a number of reasons. It puts people in harm's way. The smoke from burning buildings is much nastier than the smoke regular forest fires (especially concerning given Mill Valley's location). Most important though is the way that moving ever more people into these areas makes the necessary political calculus all but impossible.

Arguably the biggest crisis facing California at the moment is megafires. The only way to address this crisis is by aggressively promoting the good fires which we have been suppressing for over a century (unlike the native Americans who were here first). Good fires bring with them risks and those risks are primarily focused on places like Mill Valley.

Loads of other issues with this article, too many for a post. Maybe I'll come back to it, or maybe I'll point you to some of the posts I've done on the subject in the past, all of which point to the conclusion that you should never listen to the New York Times' analysis of the California housing crisis (or any other California story).

 Remember, LAT > NYT.

NIMBY and California

This is Joseph.

The recent New York Times article on the twilight of the NIMBY was interesting just for the low level of actual good ideas for why new housing is bad. The idea was to build 20 condos on a hill in a neighborhood of detached houses. 

There ensued a decade of meetings, lots of legal back and forth, and a sign that said “Save Kite Hill.” The city also got a lot of letters. They said the project was an “insane” idea that would create “unimaginable density” and lead Mill Valley toward an “LA like destruction.”

Most of the letters raised questions about parking and traffic. Others voiced a more esoteric set of concerns, like “confusion for the post office.” One writer averred that anyone who lived in the new condos would be accepting a higher cancer risk, since their homes would be downwind from the wood-fired oven at a nearby restaurant.

Obviously, the people who currently live near the restaurant are innately immune to cancer? The post office is that understaffed that they can't add addresses? I think the real reason remains this:

“From my backyard I see the hillside,” Ms. Kirsch wrote from her Hotmail account. “Explain how my property value is not deflated if open space is replace(d) with view-blocking, dense, unsightly buildings.” 

Letting house get so expensive has been a terrible idea. It creates inequality (people who own homes gain massive profit from appreciation) and drives up housing costs in general considerably. The other reasons given for why there is a housing shortage are not compelling:

Ms. Kirsch does not deny that California has a housing problem but has a different narrative about why. In her telling the state’s problems have little to do with the lack of housing — a diagnosis that unites basically every liberal and conservative economist along with the Obama, Trump and Biden administrations — but instead blames investors who buy single-family houses, big technology companies, and inequality generally. 

Well, inequality is a factor, in that home owners become wealthier if they resist growth. Not sure how technology companies can be influencing the whole of California prices. As for investors, well an artificial housing shortage is a great way to make investment profitable.  

Now I don't live in California but the general issues here have been getting obvious. Expensive housing has numerous negative externalities and the leakage to transportation issues has not been great, either. One of the hard things with writing a piece like this is that you can really only call out the extreme cases; every housing and transit issue has local considerations and a quick overview makes no sense. It takes something like this, a small development that is unlikely to cripple a neighborhood to illustrate the problem. But that does not mean that development doesn't have costs, just that it looks like they have not been balanced.

Also, worth noting that this is a well reported California example but California is simply not the worst offender and the current list is a bit counter-intuitive. The worst ranked cities in California (Los Angeles and San Jose) are still more affordable than Hamilton, Ontario. Vancouver is far worse than Seattle, and New York City is more affordable than Seattle. More importantly, California is already moving to address housing affordability, maybe not in a perfect way, whereas I do not see this at all in the Canadian context (just look at difference in scale in this Canadian plan). 

 I worry that we'll never break this curse until real estate stop looking like a "can't lose" investment.

Despite what Delaney says, age is not a significant factor in predicting cardiovascular disease and cancer.* [Blogger took this down for some reason, so we're putting it back up]

*Among undergrad college students

[Following up on Joseph's post]

I'm know this sounds like a joke but it's really not. It's one of those ideas you learn as a sophomore then probably forget even though it's a potentially major issue that crops up frequently.

Whenever you see a claim that age or exercise or diet or whatever isn't a substantial/significant driver of something, there are all sorts of distributional assumptions lurking under the surface. The more homogenous the data set of a study is with respect to a certain variable, the less likely you are to find evidence of that variable causing anything. This is a big concern because an alarming amount of research is based on groups far less diverse than the general population. Remember the old joke about experimental psychology being a discipline built on the study of lab rats and college freshmen. 

On top of that, even if a causal relationship has a trivial impact on the general population today, that impact can grow in the future if the population shifts and distributions change. The reverse can happen as well, though that's usually easier to see coming since you start out with a known relationship. 

Like I said, this is all stat 101 stuff, long internalized by most of you reading this, but it's also one of those obvious/not obvious points that is almost never spelled out explicitly, and that's a mistake on our part.

Why do people make such a big deal over fake engineers when the real thing is so cool?

Bob Sorokanich of Jalopnik introduces is to the very cool body of work of Jam Handy

How does a car’s differential work? You probably have a vague understanding. Some stuff spins, some stuff doesn’t, and somehow, the result allows your car to drive around a curve without shredding its tires or chewing up its own guts. There are gears and other gears, and it’s basically magic. That was the extent of my own understanding, until I found this vintage educational film from 1937. It’s still the best, simplest, most immediately understandable explanation of how a differential works I’ve ever found.
...
Our instructor in this lesson is Henry Jamison “Jam” Handy, a fascinating character [You should check him out -- MP] who spent much of his career making educational films like this. Most of the time, they were cleverly-disguised advertisements — most of Handy’s automotive films were done at the behest of General Motors, while others were sponsored by Standard Oil. Regardless of the topic, a Jam Handy film starts with a simple question of “how does X work,” and answers it with clear, clever, immediately understandable visual aids. Typically, the last minute of the film is where it becomes an advertisement — for example, hyping the latest technological advancement you’ll find at your friendly neighborhood Chevrolet dealer. But everything leading up to that brief sales pitch is general-interest, brand-agnostic knowledge that’s absolutely fascinating for car enthusiasts or anyone with a curious mind.

One cool piece of trivia, before the development of the differential, early cars got around the problem of the wheels spinning at different speed by using a one-wheel drive.
