More on a Nominal GDP Target
Christy Romer makes the case for a new framework for monetary policy. She is kind enough to remind us of this old paper that Bob Hall and I wrote on the topic. For more on this subject, including further links, click here.

The Rich Get Poorer
Here is a fact that you might not have heard from the Occupy Wall Street crowd: The incomes at the top of the income distribution have fallen substantially over the past few years.
According to the most recent IRS data, between 2007 and 2009, the 99th percentile income (AGI, not inflation-adjusted) fell from $410,096 to $343,927. The 99.9th percentile income fell from $2,155,365 to $1,432,890. During the same period, median income fell from $32,879 to $32,396.
These recent numbers illustrate the broader phenomenon, discussed in this paper, that high-income households have riskier-than-average incomes.

Nordhaus on Energy Economics
A smart friend recommends this article by Yale economist Bill Nordhaus. The Pigou Club endorses the conclusion:
The need for taxes on energy externalities such as carbon emissions is central to our ability to reduce the harmful side effects of economic growth. It is striking how the political dialogue in the US has ignored a policy that has so many desirable features. Perhaps, in the near future, faced with the deadline of a dire economic situation, negotiators will formulate such a policy. It would generate substantial revenues while bringing so many long-run economic and environmental benefits. Simply put, externality taxes are the best fiscal instrument to employ at this time, in this country, and given the fiscal constraints faced by the US.

The Increased Role of the Minimum Wage
I am in the process of revising my intermediate macro book. As I was updating the section on the minimum wage, I was struck by how much the data has changed over three years. The minimum wage has a much larger role now than it did three years ago, in large part because of the legislated increase in the minimum wage from $5.15 to $7.25 an hour. For example, comparing the 2010 data with the 2007 data, one finds the following:
- The percentage of all hourly-paid workers paid at or below the minimum wage rose from 2.3 to 6.0 percent.
- The percentage of part-time workers paid at or below the minimum wage rose from 5 to 14 percent.
- The percentage of teenage workers paid at or below the minimum wage rose from 7 to 25 percent.

The Monetary System of the Future?
A friend sends me this photo from some of the recent protests.
The sign says, "1. End Debt-based Fiat currencies. 2. End Fractional Reserve and Compound Interest Banking. 3. End the Fed."
Question for class discussion: What kind of monetary system would satisfy these demands? What are the pros and cons of this alternative system?

A Fun New Search Tool
Google's Ngram Viewer has been around for a while, but I just learned about it, so I thought I would mention it to my blog readers. This new search tool allows you to track and compare how often words or phrases appear in published books (at least those books in Google's database, which I gather is quite large). For example, here you can see how often Irving Fisher and John Maynard Keynes are mentioned, and here you can you see how several words associated with my career have risen over time.

Krugman on IS-LM
Paul defends the IS-LM model. I agree completely!
In some circles, there is now a push to skip the IS-LM model in intermediate macro courses and teach students more modern dynamic macro. Like Paul, I think that is a mistake. In my intermediate macro book, I have added a chapter with a dynamic macro model (which one might consider a baby DSGE model). But students are best equipped to appreciate this model after they understand IS-LM logic.
Updates: Mark Thoma reminds me that I have written on this topic before. Steve Landsburg weighs in.

Policy Uncertainty
Scott R. Baker, Nicholas Bloom, and Steven J. Davis report:
A major factor behind the weak recovery and gloomy outlook is a climate of policy-induced economic uncertainty. An index we devised shows U.S. policy uncertainty at historically high levels.

Obama versus Clinton on Tax Policy
One of the common memes about tax policy is that President Obama just wants to return the tax code to where it was during the Clinton years. The problem is, this is just not true.
This table from the Tax Policy Center is useful in dispelling the myth. Compare the far left column (Clinton-era tax policy) and the far right column (Obama's proposed tax policy). It shows the following: Compared to President Clinton, President Obama would cut the effective tax rate by about 2 percentage points for the bottom 99 percent of the population and raise the effective tax rate by about 2 percentage points for the top 1 percent of the population.
You can agree or disagree with that policy choice. But the facts are clear. President Obama's policy preferences are more focused on income redistribution (aka "class warfare") than President Clinton's tax policy ever was.

David Brooks on Mitt Romney
Brooks defends my favorite candidate. He says that Romney has "the gold standard of adviser teams."
I presume David did not have in mind that Keynes once called the gold standard a "barbarous relic."

Optimal Stabilization Policy
You can now access the published version of my recent paper with Matthew Weinzierl by clicking here. A significant change from the working paper version is the addition of thoughtful comments by the discussants Olivier Blanchard and Gauti Eggertsson.
In case you forgot what the paper is about, here is the abstract:
In case you forgot what the paper is about, here is the abstract:
This paper examines the optimal response of monetary and fiscal policy to a decline in aggregate demand. The theoretical framework is a two-period general equilibrium model in which prices are sticky in the short run and flexible in the long run. Policy is evaluated by how well it raises the welfare of the representative household. Although the model has Keynesian features, its policy prescriptions differ significantly from those of textbook Keynesian analysis. Moreover, the model suggests that the commonly used “bang for the buck” calculations are potentially misleading guides for the welfare effects of alternative fiscal policies.
