Paul Krugman on Pump-Priming and Trump

New York Times columnist Paul Krugman recently chided President Trump for imagining he invented the metaphor of “priming the pump” during an Economist interview. Yet Krugman, like Trump, buys into the premise that budget deficits really do “stimulate” total spending or “aggregate demand” which is commonly measured by growth of Nominal GDP (NGDP).

Economic booms and busts clearly have huge effects on budget deficits, but where is the evidence that deficits and surpluses have their own separate (“exogenous”) effect on NGDP? 

To isolate cause and effect, we have to take out the “endogenous” effects that ups and downs in the economy have on taxes and spending. That is why the Congressional Budget Office (CBO)estimates budget deficits or surpluses (divided by GDP) without automatic stabilizers, which has traditionally been called the “cyclically-adjusted” budget. I will label it the “C-A Deficit” for short.  

CA Deficit and NGDP

The red line in the graph shows the CBO’s Cyclically-Adjusted (C-A) deficit or surplus as a share of GDP. The blue line shows the percentage growth in Nominal GDP (NGDP). 

From 1965 to 2016, the C-A Deficit averaged -2.7% of GDP, and growth of nominal GDP averaged 6.6%.

Contrary to 1960s Keynesian orthodoxy, the graph and table reveal no connection between the size of cyclically-adjusted deficits or surpluses and the rate of growth of aggregate demand (NGDP).  From 1991 to 2001, for example, the C-A Budget swings from an average deficit to a sizable surplus with essentially no change in the pace of NGDP growth. 

There is no measurable or even visible connection between larger CA-Deficits and faster NGDP growth in 2009-2012, nor between budget surpluses and slower NGDP growth in 1998-2000.  For more than 50 years, our experience has frequently been the opposite of what demand-side fiscalism predicts. This is not just a short-term phenomenon.

Prof. Krugman: Fast and Loose with the Facts

Paul Krugman, “Killing the European Project”, NY Times, July 12, 2015: “The European project — a project I have always praised and supported — has just been dealt a terrible, perhaps fatal blow. And whatever you think of Syriza, or Greece, it wasn’t the Greeks who did it.”

Paul Krugman has always praised and supported the European project? Really? Here’s Prof. Krugman in his own words on the centerpiece of the European project, the euro:

  • Paul Krugman, “The Euro: Beware Of What You Wish For”, Fortune, December 1998: “But EMU wasn’t designed to make everyone happy. It was designed to keep Germany happy - to provide the kind of stern anti-inflationary discipline that everyone knew Germany had always wanted and would always want in future. So what if the Germans have changed their mind, and realized that they - along with all the other major governments - are more worried about deflation than inflation, that they would very much like the central bankers to print some more money? Sorry, too late: the system is already on autopilot, and no course changes are permitted.”
  • Paul Krugman, “Can Europe Be Saved?”, NY Times, January 12, 2011: “The tragedy of the Euromess is that the creation of the euro was supposed to be the finest moment in a grand and noble undertaking: the generations-long effort to bring peace, democracy and shared prosperity to a once and frequently war-torn continent. But the architects of the euro, caught up in their project’s sweep and romance, chose to ignore the mundane difficulties a shared currency would predictably encounter — to ignore warnings, which were issued right from the beginning, that Europe lacked the institutions needed to make a common currency workable. Instead, they engaged in magical thinking, acting as if the nobility of their mission transcended such concerns.”
  • Paul Krugman, “Europe’s Many Economic Disasters”, NY Times, July 3, 2015: “What all of these economies have in common, however, is that by joining the eurozone they put themselves into an economic straitjacket. Finland had a very severe economic crisis at the end of the 1980s — much worse, at the beginning, than what it’s going through now. But it was able to engineer a fairly quick recovery in large part by sharply devaluing its currency, making its exports more competitive. This time, unfortunately, it had no currency to devalue. And the same goes for Europe’s other trouble spots. Does this mean that creating the euro was a mistake? Well, yes.”

When reading Prof. Krugman’s works, it’s prudent to fact check. Prof. Krugman has always been in the Eurosceptic camp. Indeed, the essence of many of his pronouncements can be found in declarations from a wide range of Eurosceptic parties.

Tariffs on Clean Energy

Here is Paul Krugman the other day, touting President Obama’s efforts to promote clean energy:

Some things I’ve been reading lately remind me that there’s another major Obama initiative that is the subject of similar delusions: the promotion of green energy. Everyone on the right knows that the stimulus-linked efforts to promote solar and wind were a bust — Solyndra! Solyndra! Benghazi! — and in general they still seem to regard renewables as hippie-dippy stuff that will never go anywhere.

So it comes as something of a shock when you look at the actual data, and discover that solar and wind energy consumption has tripled under Obama.

True, it started from a low base, but green energy is no longer a marginal factor — and with solar panels experiencing Moore’s Law-type cost declines, we’re looking at a real transformation looking forward.

You can argue about how much this transformation owes to federal policy. …

I don’t know all the reasons why solar and wind energy consumption has tripled in recent years, but yes, you can argue about the role of federal policy here. The federal policy that I follow most closely is trade policy, and what trade policy has been doing is imposing really high import taxes on solar and wind products, thus raising their costs.  Here’s what my colleague Bill Watson and I wrote about this a while ago:

Over the last couple of years, trade remedy actions on clean energy products have intensified. In the wind industry, the Wind Tower Trade Coalition, an association of U.S. producers of wind towers, brought an AD/CVD complaint against imported wind towers in 2011. The U.S. Commerce Department started an investigation, and announced a preliminary decision in December 2012.

This decision found both subsidization and dumping in relation to Chinese imports and imposed an antidumping tariff of between 44.99% and 70.63%, as well as countervailing duties of 21.86%–34.81%. The Commerce Department also established a separate antidumping duty of 51.40%–58.49% on Vietnamese wind tower manufacturers.

In the solar industry, in October 2011, the Coalition for American Solar Manufacturing, a group of seven U.S. solar panel manufacturers led by Solar World Industries America, accused Chinese solar panel companies of dumping products in the United States. The Commerce Department opened an investigation in 2011 and announced the final ruling in 2012. The decision was to impose antidumping tariffs ranging from 24% to 36% on Chinese producers.

If we wanted to promote clean energy, the first thing we could and should do is stop imposing tariffs on these imports! 


Will Immigrants Affect Economic Policy?

The New York Times has some wonderful Room for Debate pieces debating whether the American electorate is getting more liberal.  From Molly Worthen bemoaning the rise of secular libertarianism to Robert Reich repeating the mantra of the New Deal to Kay Hymowitz arguing that Millennials are not so liberal, all are worth reading. 

If the U.S. government does adopt more liberal economic policies over the next few decade, immigrants and their descendants will not be to blame.  There are four pieces of research that lend support to this view.

More on Krugman’s Missing Libertarians

I wrote last week about Paul Krugman’s claim that “there basically aren’t any libertarians” because “There ought in principle, you might think, be people who are pro-gay-marriage and civil rights in general, but opposed to government retirement and health care programs — that is, libertarians — but there are actually very few.” I offered some evidence from Gallup, Pew, and other polls that in fact there are substantial numbers of voters who hold libertarian-ish views on both economic and social issues.

Bryan Caplan runs some regressions to find that voters’ positions on a variety of issues don’t line up the way Krugman assumes they do. Ilya Somin explores various problems with Krugman’s claims, including this:

It’s also possible to try to justify Krugman’s claim by arguing that most of those people who hold seemingly libertarian views haven’t thought carefully about their implications and are not completely consistent in their beliefs. This is likely true. But it is also true of most conservatives and liberals. Political ignorance and irrationality are very common across the political spectrum and only a small minority of voters think carefully about their views and make a systematic attempt at consistency. Libertarian-leaning voters are not an exception to this trend. But it is worth noting that, controlling for other variables, increasing political knowledge tends to make people more libertarian in their views than they would be otherwise.

Nate Silver, Krugman’s erstwhile New York Times colleague who now runs the FiveThirtyEight website, writes, “There are few libertarians. But many Americans have libertarian views.” He notes:

If Krugman is right, you should see few Americans who are in favor of same-sex marriage but oppose government efforts to reduce income inequality, or vice versa.

As it turns out, however, there are quite a number of them; about 4 in 10 Americans have “inconsistent” views on these issues.

Not actually inconsistent, of course, just not consistently “liberal” or “conservative.” Those “inconsistent” Americans just might be consistently libertarian or anti-libertarian. Silver has a nice matrix, grounded in data from the General Social Survey unlike Krugman’s off-the-cuff matrix:

Nate Silver 2015 chart on libertarian voters

On those two issues, the largest group take liberal positions on both. Substitute different issues – cutting taxes, say, or internet censorship – and you’d get larger numbers of libertarians. But whatever set of issues you choose, you’re likely going to find significant numbers of voters taking positions that don’t fit into Krugman’s two boxes.

Silver speculates on why there seems to be so little political representation for these large groups of voters:

…the hard-core partisans who vote in presidential primaries are much more likely to take consistently liberal or conservative positions than the broader American population, as Krugman’s colleague Nate Cohn points out.

And the parties themselves — who have disproportionate influence in the primaries — have highly partisan views by definition. Almost all voting in the U.S. Congress, on social issues and economic issues alike, can be reduced to a single, left-right dimension.

Does this make any sense? Why should views on (for example) gay marriage, taxation, and U.S. policy toward Iran have much of anything to do with one another? The answer is that it suits the Democratic Party and Republican Party’s mutual best interest to articulate clear and opposing positions on these issues and to present their platforms as being intellectually coherent. The two-party system can come under threat (as it potentially now is in the United Kingdom) when views on important issues cut across party lines.

Maybe that’s why we have so much trouble convincing people that there are libertarian voters.

Nate Silver looked at growing libertarian sentiment back in 2011.

Paul Krugman Can’t Find Any Libertarians

Paul Krugman has a blog post at the New York Times that seems to be based on no research at all. But it has a snappy four-cell matrix so you’ll know it’s like real economics.

Krugman’s argument is that “there basically aren’t any libertarians.” And here’s the graph that proves it:

Krugman libertarians box

See how small the letters are in two of the boxes? That shows you that there aren’t any people in those boxes. “There ought in principle, you might think, be people who are pro-gay-marriage and civil rights in general, but opposed to government retirement and health care programs — that is, libertarians — but there are actually very few.” And there are also very few people who are “socially illiberal” and supportive of government social programs, he says.

But you know, there’s research on this. David Kirby and I have done some of it, in studies on “the libertarian vote.” But two political scientists examined a similar matrix back in 1984 and found roughly even numbers of people in each box.

Part of the trick here is that Krugman has used a vague term, “socially liberal,” for one of the dimensions of the matrix, and a radical policy position, “no social insurance,” for the other dimension. The logical way would be to use either common vague terms for both dimensions – say “socially liberal/conservative” and “fiscally liberal/conservative” – or specific and similarly radical terms for both dimensions, something like “no social insurance” and “repeal all drug laws.” Wonder how many people would be in the boxes then? 

“No social insurance” is a very radical position. Even many libertarians wouldn’t support it. Like Hayek. So to find the divisions in our society, we might choose a specific issue of personal freedom – gay marriage, say – along with an equally controversial economic policy such as school choice or a constitutional amendment to balance the budget.

Krugman’s ‘Gotcha’ Moment Leaves Something to Be Desired

I’ve had some fun over the years by pointing out that Paul Krugman has butchered numbers when writing about fiscal policy in nations such as FranceEstoniaGermany, and the United Kingdom.

So I shouldn’t be surprised that he wants to catch me making an error. But I’m not sure his “gotcha” moment is very persuasive. Here’s some of what he wrote for today’s New York Times.

Gov. Jerry Brown was able to push through a modestly liberal agenda of higher taxes, spending increases and a rise in the minimum wage. California also moved enthusiastically to implement Obamacare. …Needless to say, conservatives predicted doom. …Daniel J. Mitchell of the Cato Institute declared that by voting for Proposition 30, which authorized those tax increases, “the looters and moochers of the Golden State” (yes, they really do think they’re living in an Ayn Rand novel) were committing “economic suicide.”

Kudos to Krugman for having read Atlas Shrugged, or for at least knowing that Rand sometimes referred to “looters and moochers.” Though I have to subtract points because he thinks I’m a conservative rather than a libertarian.

But what about his characterization of my position? Well, he’s right, though I’m predicting slow-motion suicide. Voting for a tax hike isn’t akin to jumping off the Golden Gate bridge. Instead, by further penalizing success and expanding the burden of government, California is engaging in the economic equivalent of smoking four packs of cigarettes every day instead of three and one-half packs.
