So it’s good to have Mike Konczal reminding us that Pinto’s definition of “subprime-like” mortgages is just something he made up — and that it turns out that his supposed high-risk categories weren’t that risky at all, that in fact they look more like traditional conforming mortgages than like true subprime:

Wow. Power plants have only a minuscule impact on emissions? In 2005, electricity generation was responsible for 73 percent of sulfur dioxide emissions, 21 percent of nitrogen oxides emissions, and 11 percent of fine particulate matter (PM2.5) emissions. And biomass plants are less efficient, per BTU, than plants that burn coal or natural gas.I'll also be mentioning biochar. Here's a relevant passage from Wikipedia:
Biochar may be a substance mostly suited to severely weathered and deprived soils (low pH, absent potassium, low or no humus). Clearly, there is the real potential for carbon sequestration, simply because biochar is so stable and is not accessible to normal microbial decay. Soils require active carbon to maintain micro and macro populations, not the inactive form found in biochar. Biochar can prevent the leaching of nutrients out of the soil, partly because it absorbs and immobilizes certain amounts of nutrients, however, too much immobilization can be harmful. It has been reported to increase the available nutrients for plant growth, but also depress them increase water retention, and reduce the amount of fertilizer required. Additionally, it has been shown to decrease N2O (Nitrous oxide) and CH4 (methane) emissions from soil, thus further reducing GHG emissions. Although it is far from a perfect solution in all economies, biochar can be utilized in many applications as a replacement for or co-terminous strategy with other bioenergy production strategies.If you're curious, you might also want to check out this this NPR story and this news release from Eurekalert.
Whatever the policy debates, households at President Obama’s dividing line might be wealthy, but that doesn’t mean they feel wealthy.Are we talking about taxable income here? The writing isn't very clear on this point and I couldn't get the link to work, so I would be inclined to assume that the phrase "household income" refers to the money coming into the household. If that's the case, then Obama's proposed tax increases wouldn't affect Mason at all.
On a Yahoo message board, a poster named Mason, who lives in Manhattan with two young children, said his household income was $262,000. “I understand the need to raise taxes,” he wrote, “but I don’t understand why people like us are lumped in with millionaires and billionaires.”
Third, high income people don’t seem to be working that much more than low income people despite the fact that a natural propensity towards work can make one high income.
Indeed, the data show us that low income folks used to work a little more, but now they work a little less than high income folks. Yet, if the income and substitution effects were balanced for each person we would still expect higher income people to work more.
That’s because working hard can lead to more education, more experience and more promotions. Being hard working is also associated with having a conscientious personality type which is itself more valuable.
So if someone was simply born with a stronger propensity to work, we would expect that person to earn more income per hour. Thus we when look at the data we should see that all these high income people are working lots of hours.
Yet, we actually don’t see that. We see only a mild effect and even then that effect is not robust over time. Sometimes, high income folks are working less.
“I came to the House as a real deficit hawk, but I am no longer a deficit hawk,” said Sen. Rick Santorum (R-Pa.). “I’ll tell you why. I had to spend the surpluses. Deficits make it easier to say no.”It's important to remember these things.
Did you know that my wife is a “high-paid consultant” for the shadowy anti-biomass movement? Neither did I — and I’m the one who handles all of our finances, so I should know.Last night she testified at a hearing held by the Springfield City Council, which is considering revoking the permit of Palmer Renewable Energy (PRE) to build a biomass plant in Springfield. PRE was granted a special zoning permit to build the plant in 2008. Since then, PRE has increased the amount of fuel it intends to burn (meaning, among other things, that more diesel trucks will have to drive in and out to deliver the material) and changed the type of fuel from construction and demolition debris to “green wood chips” (which matters because the plant was initially permitted as a recycling facility).*
My wife, a professor of environmental economics and econometrics, testified about the link between emissions (from power plants and diesel trucks) and illness, particularly asthma. At the hearing, one of PRE’s witnesses claimed not to know where my wife was “getting” the idea that air pollution can cause asthma. (In a newspaper article, PRE had this to say about asthma: “Valberg said there are many theories on the causes of asthma, and that indoor air quality in homes and schools is actually more of concern than outdoor air. For opponents to state that the project will worsen asthma rates ‘is just not scientifically accurate,’ Valberg said.”)
Well. Many, many studies have linked outdoor air pollution to asthma incidence or morbidity (Mortimer 2002, McConnell 2006, Ho 2007, Islam 2007, Loyo-Berrios 2007, Halonen 2008, O’Connor 2008 (summary here); Islam 2008 reviews studies of traffic-related asthma; Patel 2009 reviews studies of childhood asthma) and to bad cardiopulmonary health in general (Samet 2000, Pope 2002, Vedal 2003). I could come up with lots more citations, but you get the point.
...
Recently, the biomass developers have been arguing that they are the victims of a high-paid, high-powered, shadowy network of environmental activists. See for example this Springfield Republican article that largely repackages PRE’s talking points; its lead is “The developers of a proposed 35-megawatt wood-burning plant in East Springfield say the opposition to their project is well-organized, determined and well-funded.” (The Biomass Power Association blames a “small, vocal, extreme minority.”)
Well, I can tell you that my wife drove down to Springfield after work, spent four hours at the meeting, came home late at night, missed dinner, and didn’t get paid a cent.
* There is a legal issue about the standard necessary to justify revoking a permit that has already been granted, but that’s not relevant for this blog post.
So where else does the money come from? Well:
— Defined benefit pensions.
— Labor income.
— Private savings.
These three alternatives are all deeply problematic. The problems with defined benefit pensions in the public sector (chronic underfunding, etc.) are well-known, and in the private sector those problems are even more severe. Labor income is not a realistic option for people over a certain age. And private savings are, frankly, a disaster. As a country, we’ve tried to deal with the decline of defined benefit pensions by encouraging the mass middle class to engage in private retirement savings with 401(k) plans, IRAs, etc. And it doesn’t work. On the one hand, people don’t save enough. On the second hand, the tax policy is deeply regressive. On the third hand, virtually 100 percent of the management fees extracted from customers through these vehicles are value-destroying rents. On the fourth hand, it’s extraordinarily difficult for a middle class person to properly diversify his portfolio. And on the fifth hand, widespread ownership of index funds and mutual funds undermines corporate governance.
