Some Economists are Republicans

John McCain's campaign released a statement signed by 300 economists endorsing his economic plan. Most of the big names are not surprising; many are people who have served in Republican administrations. Many are obscure, but a few I recognize and some I know - my graduate econometrics professor,* for one. Its like how Bob Frank felt when he got the news about Bernanke:

"When the news first came that he was a candidate to be named a Fed governor, I thought it was interesting that the Bush administration would nominate a Democrat," Mr. Frank said. "I was surprised. I worked with him and did not know he was a Republican."

So yes, some economists are Republicans (but most are not). Although the statement begins "we enthusiastically support John McCain's economic plan," I would venture that the signatories were motivated more by their general philosophical inclinations than by excitement over what he has been offering on the campaign trail.

On said trail, McCain descended further into incoherence today with the promise to balance the budget by 2013, despite his earlier promises for big tax cuts (which he promised despite opposing the Bush tax cuts as a Senator - he actually voted against them before he was for them...). The Times' Matthew Cooper writes:

As Senator John McCain kicked off a week of economic-themed campaigning here on Monday, it was apparent that some of the underlying tensions between the two schools that guide his economic thinking — the supply-siders who want to cut taxes and the deficit hawks who want to balance the budget — remain unresolved.

Mr. McCain has promised once again to balance the budget by the end of his first term in 2013, his advisers said Monday. They were reverting to an earlier pledge that Mr. McCain abandoned in April, when he proposed a series of costly tax cuts and, citing the ailing economy, said that it might take two terms to balance the budget.

See also Mark Thoma's comments.

McCain was also telling his Colorado audience about the inspiring entrepreneurs who gave us Crocs, which turns out to be a warmed-over example, and one about a company that's now going down the tubes; more croc-pot economic ideas from the Republicans! Besides, doesn't McCain know that sandals are for socialists? (see the sixth paragraph here).

*Perhaps when he heard McCain's plans would lead to an increase in inequality, he thought that meant more like Chebychev's.

Update: Underpants gnomery, says DeLong.

Update #2 (7/10): DeLong notes notable Republican economists absent from McCain's 300, while the Politico reports some signatories are not truly enthusiastic.

Today’s airships fly with helium, as did the Hindenburg until the United States imposed an embargo on what was then a fairly valuable commodity. Hence, the Hindenburg had to start using inflammable hydrogen on its flights.

Reverse Beast Starving

One argument sometimes made by Republicans, sotto voce, for tax cuts is that budget deficits will constrain Democrats from expanding government. That is, tax cuts will "starve the beast."

In an interesting project syndicate column, Brad DeLong makes the case that since the Republican party seems to have completely broken with what was once known as fiscal conservativism (i.e. the government should not run deficits except in recessions), the next Democratic administration may not want to trim the deficit too much. He writes:

Those of us who served in the Clinton administration and worked hard to put America’s finances in order and turn deficits into surpluses are keenly aware that, after eight years of the George W. Bush administration, things look worse than when we started back in 1993. All of our work was undone by our successors in their quest to win the class war by making America’s income distribution more unequal.

A chain is only as strong as its weakest link, and it seems pointless to work to strengthen the Democratic links of the chain of fiscal advice when the Republican links are not just weak but absent. Political advisers to future Democratic administrations may argue that the only way to tie the Republicans’ hands and keep them from launching another wealth-polarizing offensive is to widen the deficit enough that even they are scared of it.

They might be right. The surplus-creating fiscal policies established by Robert Rubin and company in the Clinton administration would have been very good for America had the Clinton administration been followed by a normal successor. But what is the right fiscal policy for a future Democratic administration to follow when there is no guarantee that any Republican successors will ever be “normal” again? That’s a hard question, and I don’t know the answer.

Sounds like "starve the beast" in reverse (hat tip: Economist's View).

On a related note, Greg Mankiw sees evidence for "starve the beast," but Romer and Romer do not.

Lessons of History or Mistakes of the Past?

A specter is haunting Europe, but we can't agree on which one...

The European Central Bank is raising interest rates in an effort to keep inflation in check, while the Fed has the fed funds rate target at 2% (so the real interest rate is actually negative). Real Time Economics excerpts an analysis from Deutsche Bank that argues the trans-Atlantic divergence in monetary policy is rooted in differing historical experiences:

In the United States: “The traumatic experience of the deflation and extreme levels of unemployment that occurred during the Great Depression in the 1930s – and the Fed’s mistakes during this period — play a prominent role in the discussion of monetary policy by both practitioners and academics. Accordingly, Fed policy makers have been very sensitive to the risk of asset price collapses and debt deflation (note, for example, the Fed’s reaction to the 1987 stock market crash, the [Long-Term Capital Management] crisis, and the burst of the dot-com bubble).”

In Europe: “Probably the most prominent economic trauma in Europe were Germany’s hyperinflation after World War I and currency reform after World War II. Throughout its existence the Bundesbank was extremely sensitive to inflation pressures, and willing to take significant risks with growth to keep inflation in check (note, for example, the Bundesbank’s reaction to the two oil shocks of the 1970s and its reluctance to follow the Fed in 1987). German sensitivity to inflation risks of course had a strong influence on the institutional design of the ECB and more recently on the implementation of the euro zone’s monetary policy.”

The Telegraph's Ambrose Evans-Pritchard thinks the ECB is repeating the mistakes of the 1930's, in an excessive zeal to avoid repeating the mistakes of the 1970's:

Sadly, we are witnessing the sort of strategic errors that turned the recession of 1930 into a global catastrophe.

The European Central Bank is now hell-bent on a course of action that will have a knock-on effect across the world and risk a dangerous implosion of the credit system...

The ECB mantra is that Europe and the world is on the cusp of a wage-price spiral along the lines of the 1970s. This directly contradicts Ben Bernanke at the Fed, who insists -- correctly -- that today's conditions are not remotely like the 1970s....

By taking this militant 1970s line, he is in effect kicking Bernanke in the teeth. Or put another way, the ECB is trying to pressure America into a tighter monetary stance. Regrettably, this has in part succeeded. The Fed badly needs to cut rates further -- probably to 1per cent. It cannot do so because the ECB keeps threatening to pull the plug on the dollar.

This is madness. It is the mirror image of the early 1930s, when the Federal Reserve (cowed by the Chicago liquidationists) precipitated the collapse of 4,000 banks, and transmitted their fervour to rest of the world through the Gold Standard. This time there is no Gold Standard. But the globalised capital and currency markets -- egged on by Trichet -- are playing much the same role.

That comes to my attention via Naked Capitalism. This is not the first time the choice of the correct historical analogy has been at issue (see, e.g., this earlier post).

"Blood and Guts" Volcker

The Economist's Free Exchange raises the interesting question of whether academic credentials - like those of Ben Bernanke - are valuable for central bankers. Paul Volcker (Fed chairman, 1979-87) apparently takes a rather Stephen Colbert-ian view of the issue:

A central bank governor's most essential trait was "guts" and some management abilities, said Mr Volcker.

Guts?! Hmm... by that logic, perhaps Curt Schilling should replace Bernanke when his term expires, or maybe Ponch from "CHiPs"...

Free Exchange notes that

Mr Volcker does not have an economics PhD; he has a Harvard MA in political economy and two years of study at the London School of Economics. Despite this, he is frequently called the best central banker ever.

Volcker is often lauded for his "toughness" in presiding over the disinflation of the early 1980's, when the Fed tightened monetary policy (the Federal Funds rate exceeded 19% in mid-1981) to bring inflation down. Undoubtedly, that episode was difficult for Volcker, who took some harsh criticism, but the truly severe consequences were suffered by the millions of workers who lost their jobs in the ensuing recession; the unemployment rate peaked at 10.8% in 1982.

The ardent praise sometimes lavished on Volcker for his "courage" in the "fight" against inflation reminds me of the scene from "Patton" when a soldier says: "There he goes, 'ol' blood 'n guts.'" His buddy replies: "Yeah, our blood, his guts."

Arguably, there was no painless way to put a stop to the inflation that had taken hold in the 1970's, but I sometimes like to think that a smart PhD economist might have found a way to do so with less damage.

Dubious Cap-and-Trade Skepticism

In a Washington Post op-ed, Bjorn "the Skeptical Environmentalist" Lomborg argues that more government funding for research is a better way to reduce carbon emissions than a cap-and-trade system, as in the Lieberman-Warner bill (recently fillibustered by Senate Republicans). He writes:

Politicians favor the cap-and-trade system because it is an indirect tax that disguises the true costs of reducing carbon emissions. It also gives lawmakers an opportunity to control the number and distribution of emissions allowances, and the flow of billions of dollars of subsidies and sweeteners.

Many people believe that everyone has a moral obligation to ask how we can best combat climate change. Attempts to curb carbon emissions along the lines of the bill now pending are a poor answer compared with other options.

Consider that today, solar panels are one-tenth as efficient as the cheapest fossil fuels. Only the very wealthy can afford them. Many "green" approaches do little more than make rich people feel they are helping the planet. We can't avoid climate change by forcing a few more inefficient solar panels onto rooftops.

The answer is to dramatically increase research and development so that solar panels become cheaper than fossil fuels sooner rather than later. Imagine if solar panels became cheaper than fossil fuels by 2050: We would have solved the problem of global warming, because switching to the environmentally friendly option wouldn't be the preserve of rich Westerners.

Lomborg seems to miss the point of a cap-and-trade: by making it more costly to emit carbon, the system would create incentives to develop energy alternatives and increase efficiency (a carbon tax would do the same thing). By changing relative prices, cap-and-trade will create opportunities for firms, entrepreneurs and inventors in the private sector to profit from developing less carbon-intensive methods of producing energy and products that use less energy. It would also give everyone an incentive to be less wasteful by bringing the price of carbon emissions in line with the true cost (i.e. reflecting the private as well as social costs).

Though government research grants might be helpful (as an academic, I can't argue against throwing more money at universities...) using market forces to mobilize the private sector is likely to be a more effective, lower-cost way of getting us to those cheap solar panels.

That logic is standard intermediate microeconomics, but Lomborg - who has a PhD in political science - doesn't appear to get it.

Whose Main Street?

If I had been born a decade earlier, I might have grown up to be a Kremlinologist (probably for the best that I wasn't!). Perhaps the most comparable job today is that of Fed-watcher (or maybe NY Mets front office-watcher).

Today, Washington Post FOMC-ologist Nell Irwin sees evidence of division in the marble temple:

In contrast to the consensus that characterized the Fed for most of the past 20 years, there are now divisions over some of the most fundamental challenges that Fed Chairman Ben S. Bernanke is facing: how to combat the financial crisis, the slumping economy and high inflation.

These divisions are rooted in the structure of the Fed -- which includes 12 regional banks with independent boards of directors, and a central board of governors in Washington chaired by Bernanke -- but have come to the fore only because of the twin problems of weak growth and inflation.

Presidents of the regional banks are appointed by bankers and businesspeople in their communities and, like them, tend to put a premium on keeping inflation in check. The Board of Governors, along with the New York regional bank, has been more attuned to the troubles roiling financial markets, such as those for complicated debt securities and the spillover into the wider economy.

"The presidents bring a wealth of knowledge acquired from their regional contacts," Bernanke said in a speech dedicating the new headquarters of the Kansas City Fed earlier this month.

"Thus, in making policy, we are able to view the economy not just from a Washington perspective or a Wall Street perspective but also from a Main Street perspective."

As Irwin explains, the regional Fed presidents tend to be more "hawkish" (i.e. inclined to favor higher interest rates). However, this doesn't mean that they represent "Main Street," or at least not all of it. The regional Feds are owned by the member banks, which elect most of the board members, and the board chooses the bank presidents. So, it would probably be more accurate to say that the regional Fed presidents represent the interests of Main Street banks, but I would think many that other "Main Street" businesses - a car dealership or real estate agency, for example - would prefer lower rates, even at the risk of higher inflation (I'm not sure about the establishments on Bob Seger's "Main Street"; their business might be counter-cyclical).

Tom Wolfe, Schumpeterian

A year ago, just before the credit market crisis began, Tom Wolfe visited the New York Stock Exchange and declared: "we may be watching the end of capitalism as we know it." The Times' Andrew Ross Sorkin has an interesting follow up:

When I asked Mr. Wolfe about his comment on the floor of the stock exchange, he said, “I didn’t realize anyone would take me seriously.” He says he has since made up an explanation of why he thought it could be the end of capitalism.

Citing Joseph A. Schumpeter, the economist, Mr. Wolfe said, “Stocks and bonds are what he called evaporated property. People completely lose touch of the underlying assets. It’s all paper — these esoteric devices. So it has become evaporated property squared. I call it evaporated property cubed.”

Then he cautioned, “Of course, I’m not an economist.” Maybe that’s why he’s gotten it so right.

So, does this mean the 1980's are over for real this time?

GPM = 1/MPG

One might think of the "fuel economy" of a car as the amount of gas needed to travel a given distance - the number of gallons per mile - which is the reciprocal of the common miles per gallon measure. Discussing fuel economy in terms of miles per gallon is therefore somewhat deceptive - e.g., the improvement in efficiency of going from 25 to 43 MPG is about the same as going from 10 to 12 MPG (in both cases 0.0167 GPM). The Guardian reports on a study by two Duke management professors explaining exactly that.

The Candidates get a Fiscal Exam

The Tax Policy Center has made a preliminary analysis (with slight revisions) of McCain and Obama's tax plans. Under current law, most of the tax cuts passed in 2001 and 2003 are scheduled to expire after 2010 - i.e., if nothing is done, there will be a significant tax increase in 2011 (returning us to the higher tax rates we had back in the Clinton years, when the economy was growing faster, unemployment was lower, and the federal budget was in surplus...). Relative to this, both candidate's plans would reduce revenue - McCain by $3.6 trillion and Obama by $2.7 trillion over 10 years (or, compared to keeping the current tax code in place, Obama would raise revenue by $262 billion while McCain would reduce it by $615 billion). Federal tax revenue was 18.8% of GDP in 2007 - under McCain's plan it is projected to be 17.9% of GDP over 2009-2018, versus 18.4% under Obama's.

Both candidates' proposals are multifaceted; highlights include:

McCain would extend almost all of the 2001-03 tax cuts (except that a 15% tax would remain in place on estates over $5 million), increase the tax exemption for dependents and reduce the maximum corporate tax rate from 35% to 25%.

Obama would extend the portions of the tax cuts affecting lower- and middle- income households, but allow the top tax rates to revert to their 2000 levels (e.g. the top income tax rate would return to 39.6% from its current 35%) and raise capital gains and dividend taxes. Lower and middle-income families would also be the beneficiaries of more tax credits: he would add a $500 "Making Work Pay" tax credit, expand the Earned Income Tax Credit (EITC) and the child and dependent care tax credits.

The distributional effects of the two plans are very different: Obama's plan would raise the average federal tax rate in 2009 for the highest-income quintile (i.e. the top 20%), and lower it for the remaining 80%. The cut would be 5.3 percentage points for the bottom quintile and 2 pts for the middle quintile, while the top 20% would see a 1.5 pt increase (and the top 1% would see their tax rate increase by 6.1 pts). Under McCain's plan, the average federal tax rate for all groups, but the decrease for the bottom quintile (0.2 pts) and middle (0.6 pts) are small compared to the change at the top (2.2 pts for the top quintile).

The study has a number of caveats. The center had to make some assumptions because proposals are vague - the report says "no one - not even inside the campaigns - knows exactly what the proposals are. Stump speeches and campaign white papers are often short on the technical details needed to analyze the proposals fully." Also, the analysis did not tackle the candidates' plans regarding health care, which will also affect the tax code (the TPC promises a separate study on this).

EconomistMom examined the distributional consequences; here's her answer to the Telly Savalas question ("who loves ya, baby"):

So in aggregate, at least in terms of tax cuts, McCain loves taxpayers (even) more than Bush loves taxpayers, and Bush loves taxpayers more than Obama loves taxpayers. All of them are not so fond of our children and grandchildren though, because they’re all willing to have our children and grandchildren (aka future taxpayers) pay for all that love they’re willing to give to us current taxpayers.

But how much the candidates love you, in particular, depends a great deal on how “rich”, or not, you are. With his tax cuts, Senator Obama loves those who are not so rich a lot more than he loves those who are. Senator McCain, on the other hand, really loves the really rich. In fact, with his tax cuts, Senator McCain loves the really rich even more than President Bush has loved them.

And Paul Krugman says:

The key point, again: because of all those middle-class tax cuts in the Obama plan, he collects only 0.4% of GDP more in taxes than McCain. The tax collection comes from different people: lower and middle-income Americans would be substantially better off under the Obama plan. But where is the money for health care reform?

Krugman also wrote a column on the subject (his numbers are slightly different because they are prior to the TPC's revision of its estimates), and Clive Crook did too.

The TPC's analysis does not include Obama's proposal - which is still lacking specifics (maybe we should call it a "gambit" for now) - to apply the social security payroll tax to higher-income owners (currently, income above $102,000 is not subject to social security contributions). Back in November, this came up in a debate between Clinton and Obama (see this post for a discussion). Obama says that the tax would kick back in for incomes above $250,ooo (i.e. there would be a 'donut hole'). While the problems of social security are often exaggerated, this would make the tax code more progressive (and the top marginal rate would be getting pretty high, for those who worry about such things) and reduce the amount the government needs to borrow from the "public" (or, really, China), because the social security trust fund would buy some of the Treasury bonds that would otherwise have to be sold to finance the deficit. That should be a plus for investment (less "crowding out") and the current account. The TPC says:

Senator Obama not been clear about what rate would apply, when the tax would take effect, or even what the tax base would be. (See our follow-up blog post.) Assuming that the proposal would apply the full 6.2 percent OASDI (old age survivors and disability insurance) tax, paid by both employers and employees, to earnings above the threshold, TPC estimates that the proposal would raise $629 billion, or about 0.4 percent of GDP, over the ten-year budget period.
