the joy of research

Monday, February 7th, 2011

Paul Krugman explains why he writes columns.

[W]hat I really love is doing the research — puzzling out how health systems work, what’s going on with monetary policy, how to access and interpret data about the wheat market.

But wouldn’t I be doing research even if I had never strayed beyond academics? Yes, but; the trouble with being a successful senior academic is that it’s all too easy to get into a rut, to spend your time doing minor twiddles on the work that made you a big wheel; plus, even great economists rarely do pathbreaking work by the time they’re my age. That’s why lots of first-rate economists seek out second careers of one kind or another, whether it’s in administration, in public affairs, or whatever.

In my case it’s writing for the broader public. The great thing about the column is that it more or less forces me to keep learning new tricks, to keep scoping out areas I’d never thought much about before. Then it forces me to find a way to talk about those areas in plain English.

the myth of a failing Europe

Friday, January 28th, 2011

The official Republican response to President Obama’s State of the Union address, delivered by Representative Paul Ryan, urges lawmakers to cut spending quickly, to avoid the mistakes of European countries. But Republicans place European countries in a single bag, assuming that all behaved like Greece.

We believe the days of business as usual must come to an end. We hold to a couple of simple convictions: Endless borrowing is not a strategy; spending cuts have to come first. ….

Just take a look at what’s happening to Greece, Ireland, the United Kingdom and other nations in Europe. They didn’t act soon enough; and now their governments have been forced to impose painful austerity measures: large benefit cuts to seniors and huge tax increases on everybody.

Remarks of Congressman Paul Ryan (R-WI)“, Washington, DC, 25 January 2011.

Paul Ryan (1970-), who has represented Wisconsin’s 1st district in the US Congress since 1999, now chairs the House Budget Committee.

Princeton economist Paul Krugman, in a NY Times column, exposes the Republican “myth of a failing Europe”, the myth of “a collapsing society groaning under the weight of Big Government”.

It’s a good story: Europeans dithered on deficits, and that led to crisis. Unfortunately, while that’s more or less true for Greece, it isn’t at all what happened either in Ireland or in Britain, whose experience actually refutes the current Republican narrative. ….

Let’s talk about what really happened in Ireland and Britain.

On the eve of the financial crisis, conservatives had nothing but praise for Ireland, a low-tax, low-spending country by European standards. …. And the truth was that in 2006-2007 Ireland was running a budget surplus, and had one of the lowest debt levels in the advanced world.

So what went wrong? The answer is: out-of-control banks; Irish banks ran wild during the good years, creating a huge property bubble. When the bubble burst, revenue collapsed, causing the deficit to surge, while public debt exploded because the government ended up taking over bank debts. And harsh spending cuts, while they have led to huge job losses, have failed to restore confidence.

The lesson of the Irish debacle, then, is very nearly the opposite of what Mr. Ryan would have us believe. It doesn’t say “cut spending now, or bad things will happen”; it says that balanced budgets won’t protect you from crisis if you don’t effectively regulate your banks ….

What about Britain? Well, contrary to what Mr. Ryan seemed to imply, Britain has not, in fact, suffered a debt crisis. True, David Cameron, who became prime minister last May, has made a sharp turn toward fiscal austerity. But that was a choice, not a response to market pressure.  ….

[T]here’s certainly no sign of the surging private-sector confidence that was supposed to offset the direct effects of eliminating half-a-million government jobs. And, as a result, there’s no comfort in the British experience for Republican claims that the United States needs spending cuts in the face of mass unemployment.

Paul Krugman, “Their Own Private Europe“, New York Times, 28 January 2011.

Elsewhere in the news today, contrary to Republican expectations, there is increased confidence in the euro, and in Europe’s ability to overcome its debt crisis.

[S]ince hitting a low of $1.2871 against the dollar on January 10, the euro has surged 6.9 per cent, notching up a two-month peak of $1.3759 on Thursday.

Sentiment towards the euro has improved dramatically ….

Thomas Stolper, strategist at Goldman Sachs, says there is potential for further gains in the euro. He forecasts a move to $1.40 against the dollar in three months followed by a gradual drift higher to $1.50 later in a year.

the US political divide

Friday, January 14th, 2011

One side of American politics considers the modern welfare state — a private-enterprise economy, but one in which society’s winners are taxed to pay for a social safety net — morally superior to the capitalism red in tooth and claw we had before the New Deal. It’s only right, this side believes, for the affluent to help the less fortunate.

The other side believes that people have a right to keep what they earn, and that taxing them to support others, no matter how needy, amounts to theft. That’s what lies behind the modern right’s fondness for violent rhetoric: many activists on the right really do see taxes and regulation as tyrannical impositions on their liberty.

There’s no middle ground between these views. ….

In a way, politics as a whole now resembles the longstanding politics of abortion — a subject that puts fundamental values at odds, in which each side believes that the other side is morally in the wrong. Almost 38 years have passed since Roe v. Wade, and this dispute is no closer to resolution.

Yet we have, for the most part, managed to agree on certain ground rules in the abortion controversy: it’s acceptable to express your opinion and to criticize the other side, but it’s not acceptable either to engage in violence or to encourage others to do so.

What we need now is an extension of those ground rules to the wider national debate.

the financial crisis in Europe

Friday, January 14th, 2011

Princeton economist Paul Krugman has written for the New York Times a long essay on Europe. The first five pages of the article contain nothing new for those who have followed events in Europe, but don’t miss the last part.  Beginning on page 6, Krugman draws parallels with Argentina, and examines the implications of four alternative paths to recovery: “toughing it out” (fiscal austerity); “debt restructuring” (default); “full Argentina” (exit the euro); and “revived Europeanism” (fiscal transfers from strong to weak governments).

Here is Krugman on the first option; read more at the link.

For now, the plan in Europe is to have everyone tough it out — in effect, for Greece, Ireland, Portugal and Spain to emulate Latvia and Estonia. That was the clear verdict of the most recent meeting of the European Council, at which Angela Merkel, the German chancellor, essentially got everything she wanted. Governments that can’t borrow on the private market will receive loans from the rest of Europe — but only on stiff terms: people talk about Ireland getting a “bailout,” but it has to pay almost 6 percent interest on that emergency loan. There will be no E-bonds; there will be no transfer union.

Even if this eventually works in the sense that internal devaluation [i.e. deflation] has worked in the Baltics — that is, in the narrow sense that Europe’s troubled economies avoid default and devaluation — it will be an ugly process, leaving much of Europe deeply depressed for years to come. There will be political repercussions too, as the European public sees the continent’s institutions as being — depending on where they sit — either in the business of bailing out deadbeats or acting as agents of heartless bill collectors.

private debt and public debt

Friday, November 26th, 2010

This is not the main point of Martin Wolf’s column, but it is just as important:

Some insist loudly that one cannot solve a problem caused by too much debt by piling on more debt. But that is wrong. In the US and UK, net debt is close to zero: thus, debt is not a burden on society as a whole, but an obligation of some residents to others. As Nobel-laureate Paul Krugman points out, debt matters only because of who the debtors are. If, for example, debtors suffer an unexpected loss in net wealth or are forced suddenly to repay, the impact on the economy is bound to be fiercely contractionary. If the state can borrow, to offset this effect, it should do so. That would not impose an overall burden on a society, since net debt would remain close to zero. If it also raised GDP above what it would otherwise be, that would surely be a very good thing.

Martin Wolf, “Assets matter just as much as debt”, Financial Times, 26 November 2010.

Martin links to Paul Krugman’s VoxEu column, which summarizes a new paper: Gauti Eggertsson and Paul Krugman, “Debt, Deleveraging, and the Liquidity Trap: A Fisher-Minsky-Koo approach”, mimeo, 16 November 2010.

Paul Krugman is brilliant, and a great communicator. For reasons that I do not fully understand, he provokes outbursts of rage from some who disagree with him.

Nick Rowe, for example, recently posted some thoughts on on the Eggertsson-Krugman paper. It generated numerous comments, most of which were on topic. But an ‘Austrian’ economist attacked Paul Krugman rather than his model. An anonymous contributor (“brendon”) wrote:

There is something about Paul Krugman that makes people lose their minds – for example, someone in these comments starting with “I’ll say this so that even Paul Krugman can understand it” – the man has a Nobel Prize, a John Bates Clark Medal and tenure at Princeton. I think he understands plenty.

Nick’s co-blogger, Stephen Gordon, added:

Greg, there are any number of websites where people can indulge in Krugman Derangement Syndrome to their heart’s content. WCI will not be one of them. If you want to talk about the paper Nick is discussing, fine. But let’s keep it at that, shall we?

Nick Rowe, “Some thoughts on the Gauti Eggertsson & Paul Krugman paper”, Worthwhile Canadian Initiative, 19 November 2010.

I agree with Mr Gordon. Ad hominem attacks have no place in civilised discourse. They fan emotions, but do not contribute to our understanding of issues.

Roubini on Obama

Friday, October 29th, 2010

NYU economist Nouriel Roubini, in his contribution to a week-long FT debate, criticizes Obama and his party for failure to address the problem of medium-term deficits. “The result”, he writes, “will soon be the worst of all worlds: neither short-term stimulus nor medium-term fiscal sustainability”.

What has been the fiscal performance of President Barack Obama? He inherited the worst economic crisis since the Great Depression, as well as a budget deficit that – after much needed bail-outs and a series of reckless tax cuts – was already close to $1,000bn. His stimulus package, together with a backstop of the financial system, low rates and quantitative easing from the Federal Reserve, prevented another depression. Mr Obama also deserves credit that the US, alone among advanced economies, currently supports a “growth now”, rather than an “austerity now” path.

But this is but one half of the picture; we must also judge his first two years on his ability to anticipate what the economy will need tomorrow. Here the picture is much less positive. Given the likely path of fiscal policy after next Tuesday’s election – with the expiration of existing stimulus and transfer payments, and even with most of the 2001-03 tax cuts being kept – the US economy will soon experience serious fiscal drag just when it needs a further boost. ….

In an ideal world Mr Obama would also have been able to move towards reforming and reducing entitlement spending, with commitments to measures that could be phased in over the next few years, therefore avoiding short-term fiscal pain. He would also have committed to increase, gradually over the next few years, less distortionary taxes such as a VAT and a carbon tax. This would have reduced the fiscal deficit, and created a climate in which no investor would worry about additional stimulus.

Sadly, this has not happened. In fact the opposite will now take place.

Nouriel Roubini, “A presidency heading for a fiscal train wreck”, Financial Times, 29 October 2010.

Roubini’s views support those of Princeton economist Paul Krugman, who writes:

[W]e very much need active policies on the part of the federal government to get us out of our economic trap.

But we won’t get those policies if Republicans control the House. In fact, if they get their way, we’ll get the worst of both worlds: They’ll refuse to do anything to boost the economy now, claiming to be worried about the deficit, while simultaneously increasing long-run deficits with irresponsible tax cuts — cuts they have already announced won’t have to be offset with spending cuts.

Paul Krugman, “Divided We Fail”, New York Times, 29 October 2010.

A key difference between the two economists is that Roubini does not blame the Republicans for virtually everything. Roubini acknowledges that Obama “is limited by an unco-operative Republican party”, but adds that Democrats “have been unwilling to tackle long-term entitlement spending … and this means the US remains on an unsustainable fiscal course”.

Keynes versus the classics

Saturday, October 2nd, 2010

I rarely link to Paul Krugman, on the assumption that everyone reads his columns and his blog. But this post is too good to ignore.

The 10-year bond rate is about 2.5 percent, lower than it was when [Niall] Ferguson made that prediction [of rising interest rates from fiscal stimulus]. Inflation keeps falling. The attacks on Keynesianism now come down to “but unemployment has stayed high!” which proves nothing — especially because if you took a Keynesian view seriously, it suggested even given what we knew in early 2009 that the stimulus was much too small to restore full employment.

The point is that recent events have actually amounted to a fairly clear test of Keynesian versus classical economics — and Keynesian economics won, hands down.

Paul Krugman, “How The Other Half Thinks”, New York Times Blog, 2 October 2010.

Jeffrey Sachs on stimulus

Thursday, July 22nd, 2010

The “austerity debate” continues at the Financial Times. Today there is only one contribution, from Columbia University economist Jeffrey Sachs. Professor Sachs agrees there is need for stimulus, but argues that what needs to be stimulated is investment, not consumption.

The striking feature in the current debate about austerity and stimulus has been the lack of attention to investment. Consumers will not provide the engine of recovery, nor should they after overspending for a decade. Instead, the US and Europe should be using the recent corrective boost in saving rates to promote long-term investments in physical and human capital as the proper way back to sustained growth. ….

At a time when China is building hundreds of miles of subway lines, tens of thousands of miles of highways, a couple of dozen nuclear power plants, and a network of tens of thousands of miles of high-speed intercity rail lines, the US struggles to launch a single substantial project. China saves and invests; the US talks, consumes, borrows, and talks some more.

It is wrong in this context to believe that the only choice is further fiscal stimulus versus a repeat of the Great Depression. Further short-term tax cuts or transfers on top of America’s $1,500bn budget deficit are unlikely to do much to boost demand, while they would greatly increase anxieties over future fiscal retrenchment. Households are hunkering down, and many will regard an added transfer payment as a temporary windfall that is best used to pay down debt, not boost spending.

Jeffrey Sachs, “Sow the seeds of long-term growth”, Financial Times, 22 July 2010.

Sachs’ proposal for a “US investment recovery plan” consists of government spending on clean energy and infrastructure and “more education spending at secondary, vocation and bachelor-degree levels”.

Paul Krugman, who works for a rival newspaper, is not participating in the FT debate. Nonetheless, Krugman is clearly in the stimulus camp on this issue. In two blog posts (here and here), Krugman responded to Ken Rogoff’s assertion that there is “No need for a panicked fiscal surge”.

why The Economist is no longer worth reading

Friday, May 7th, 2010

It is a pity that The Economist, which used to be a sensible – indeed, excellent – newspaper, has fallen to such depths that I rarely read it. Here is a recent example, penned by “Buttonwood”:

It is a standard conservative argument that taxes on companies end up being taxes on everyone, since they will be passed on to consumers in the form of higher prices. But of course, it works the other way round; cuts in benefits for the poor, on in public sector payrolls, lead to lower demand for the goods and services that companies produce.

Buttonwood, “Democratic deficit”, Buttonwood’s notebook, 5 May 2010.

The writer is author of The Economist‘s column on financial markets.

Buttonwood’s analysis is flawed and incomplete. Everyone – producers and consumers alike – benefits from the stimulus of tax cuts and government spending only in times of recession and high unemployment. In normal times the standard argument applies, although it is somewhat more complex than assumed by Buttonwood. A full explanation can be found in any basic textbook, such as Greg Mankiw’s popular Principles of Economics:

Who Pays the Corporate Income Tax?

The corporate income tax provides a good example of the importance of tax incidence for tax policy. The corporate tax is popular among voters. After all, corporations are not people. Voters are always eager to have their taxes reduced and have some impersonal corporation pick up the tab.

But before deciding that the corporate income tax is a good way for the government to raise revenue, we should consider who bears the burden of the corporate tax. This is a difficult question on which economists disagree, but one thing is certain: People pay all taxes. When the government levies a tax on a corporation, the corporation is more like a tax collector than a taxpayer. The burden of the tax ultimately falls on people—the owners, customers, or workers of the corporation.

Many economists believe that workers and customers bear much of the burden of the corporate income tax. To see why, consider an example. Suppose that the U.S. government decides to raise the tax on the income earned by car companies. At first, this tax hurts the owners of the car companies, who receive less profit. But over time, these owners will respond to the tax. Because producing cars is less profitable, they invest less in building new car factories. Instead, they invest their wealth in other ways—for example, by buying larger houses or by building factories in other industries or other countries. With fewer car factories, the supply of cars declines, as does the demand for autoworkers. Thus, a tax on corporations making cars causes the price of cars to rise and the wages of autoworkers to fall.

The corporate income tax shows how dangerous the flypaper theory of tax incidence can be. The corporate income tax is popular in part because it appears to be paid by rich corporations. Yet those who bear the ultimate burden of the tax—the customers and workers of corporations—are often not rich. If the true incidence of the corporate tax were more widely known, this tax might be less popular among voters.

“Corporate Tax Rates”, Greg Mankiw’s blog, 3 May 2006.

Mankiw is conservative, so readers might infer that this is a conservative argument. I don’t think so. If my memory is correct, a similar statement can be found in any principles text. I am travelling, so do not have easy access to textbooks, but if anyone doubts this, check out, for example, a text authored by two economists – Paul Krugman and Robin Wells – who are definitely not conservative. Chapter 7 of their book, Economics, is titled “Taxes”, so might be a good place to search. If you find any passage that differs from Mankiw’s statement, please let me know: comments are open!

lessons of the euro crisis

Friday, April 30th, 2010

I normally avoid quoting from Krugman’s NY Times column, assuming that everyone reads it. But his column today is too important to ignore.

The deficit hawks are already trying to appropriate the European crisis, presenting it as an object lesson in the evils of government red ink. What the crisis really demonstrates, however, is the dangers of putting yourself in a policy straitjacket. When they joined the euro, the governments of Greece, Portugal and Spain denied themselves the ability to do some bad things, like printing too much money; but they also denied themselves the ability to respond flexibly to events.

Paul Krugman, “The Euro Trap”, New York Times, 30 April 2010.

Krugman points out that none of these countries were in serious fiscal difficulties prior to the 2008 financial crisis – Spain’s budget was actually in surplus! Yet all three are in deep trouble today. By joining the euro, countries give up all possibility of using currency devaluation to reduce wages and costs relative to their trading partners. The United Kingdom retained its national currency, so has been able to adjust wages (increase competitiveness) by devaluation rather than deflation. Countries in the euro zone can increase their competitiveness only by deflation, which is difficult and painful, with more unemployment, compared to adjustment with flexible exchange rates.

The future is not bright for Greece, Portugal and Spain.
