Trump and Reagan

January 28, 2017 1 comment

A couple of days ago I had an interesting debate hosted by France 24, on Trumponomics. Interesting because there was an overall agreement between me and Dan Mitchell from Cato Institute, even if from totally opposite points of view, on the fact that Trumponomics does not exist. The Donald is pushing forward a number of inconsistent measures, whose final effect is impossible to forecast (except that it is a safe bet to say that it will not end well).

Mitchell argued of course that the only good policies imply the downsizing of the government. As one can easily imagine I would tend to disagree. And over and over again, during the 40 or so minutes of discussion, came back the reference to the golden era of Ronald Reagan. Trump needs to cut taxes, as Reagan did, and downsize government, as Reagan did. And growth and unemployment will return, as under Reagan

When I said that the problem of the US was not the lack of jobs per se, but rather the increasingly unequal distribution of income, that started precisely under Reagan, Mitchell replied that this was false (I officially spread fake truths!), claiming that median income under Reagan increased. Well, think again. An old post by Paul Krugman had already dispelled the mith, and I had written on it myself. I copy the figure from that post (updated) here:



So, while it is true that median income increased under Reagan-Bush (Mitchell is formally right), it is hard to define it an era or decreasing inequality I My conclusion back then was that growth does not lift all boats, and trickle-down economics does not exist. And Reagan did not do that well in terms of growth either. And did I mention twin deficits?

Just a final remark. The downsizing of government under Reagan is also a myth (which is rather good news, by the way): Look at OECD data:2017_01_trump_and_reagan


I rest my case. People at Cato should pick their role models more carefully.



A Piketty Moment

October 25, 2016 6 comments

Update (10/27): Comments rightly pointed to different deflators for the two series. I added a figure to account for this (thanks!)

Via Mark Thoma I read an interesting Atalanta Fed Comment about their wage tracker, asking whether the recent pickup of wages in the US is robust or not.

The first thing that came to my mind is that we’d need a robust and sustained increase, in order to make up for lost ground, so I looked for longer time series in Fred, and here is what I got


This yet another (and hardly original) proof of the regime change that occurred in the 1970s, well documented by Piketty. Before then, US productivity (output per hour) and compensation per hour  roughly grew together. Since the 1970s, the picture is brutally different, and widely discussed by people who are orders of magnitude more competent than me.

[Part added 10/27: Following comments to the original post, I added real compensation defled with the GDP deflator.  While this does not account for purchasing power changes, it is more directly comparable with real output. Here is the result:


The commentators were right, the divergence starts somewhat later, in the early 1980s. This makes it less of a Piketty moment, while leaving the broad picture unchanged.]

Next, I tried to ask whether it is better for wage earners, in this generally gloomy picture, to be in a recession or in a boom. I computed the difference between productivity (output per hour) and wages (compensation per hour), and averaged it for NBER recession and expansion periods (subperiods are totally arbitrary. i wanted the last boom and bust to be in a single row). Here is the table:

Yearly Average Difference Between Changes in Productivity and in Wages
In Recessions In Expansions Overall % of Quarters in Recession
1947-2016 1.51% 0.40% 0.57% 15%
1947-1970 1.62% -0.14% 0.19% 19%
1970-2016 1.42% 0.67% 0.76% 13%
1980-1992 0.64% 0.84% 0.81% 17%
1993-2000 N/A 0.68% 0.68% 0%
2001-2008Q1 4.07% 1.10% 1.41% 10%
2008Q2-2016Q2 2.17% 0.12% 0.49% 18%
Source: Fred (my calculations)
Compensation: Nonfarm Business Sector, Real Compensation Per Hour
Productivity: Nonfarm Business Sector, Real Output Per Hour

No surprise, once again, and nothing that was not said before. The economy grows, wage earners gain less than others; the economy slumps, wage earners lose more than others.  As I said a while ago, regardless of the weather stones keep raining. And it rained particularly hard in the 2000s. No surprise that inequality became an issue at the outset of the crisis…

There is nevertheless a difference between recessions and expansions, as the spread with productivity growth seems larger in the former. So in some sense, the tide lifts all boats. It is just that some are lifted more than others.

Ah, of course Real Compensation Per Hour embeds all wages, including bonuses and stuff. Here is a comparison between median wage,compensation per hour, and productivity, going as far back as data allow.


I don’t think this needs any comment.

The Blanchard Touch

April 15, 2015 10 comments

Yesterday I commented on the intriguing box in which the IMF staff challenges one of the tenets of the Washington consensus, the link between labour market reform and economic performance.
But the IMF is not new to these reassessments. In fact over the past three years research coming from the fund has increasingly challenged the orthodoxy that still shapes European policy making:

  1. First, there was the widely discussed mea culpa in the October 2012 World Economic Outlook, when the IMF staff basically disavowed their own previous estimates of the size of multipliers, and in doing so they certified that austerity could not, and would not work (of course this led EU leaders to immediately rush to do more of the same).
  2. Then, the Fund tackled the issue of income inequality, and broke another taboo, i.e. the dichotomy  between  fairness and efficiency. Turns out that unequal societies tend to perform less well, and IMF staff research reached the same conclusion. And once the gates opened, it did not stop. The paper by Berg and Ostry was widely read. Then we had Ball et al on the distributional effects of fiscal consolidation (surprise, it increases inequality). Another paper investigated the channels for this link, highlighting how consolidation leads to increased inequality mostly via unemployment. And just last week I assisted to a presentation by IMF economists showing how austerity and inequality are positively related with political instability.
  3. On labour markets, before yesterday’s box 3.5, the Fund had disseminated research linking increased inequality with the decline in unionization.
  4. Then, of course, the “public Investment is a free lunch” chapter three of the World Economic Outlook, in the fall 2014.
  5. In between, they demolished another building block of the Washington Consensus: free capital movements may sometimes be destabilizing…

These results are not surprising per se. All of these issues are highly controversial, so it is obvious that research does not find unequivocal support for a particular view. All the more so if that view, like the Washington Consensus, is pretty much an ideological construction. Yet, the fact that research coming from the center of the empire acknowledges that the world is complex, and interactions among agents goes well beyond the working of efficient markets, is in my opinion quite something.

What does this mass (yes, now it can be called a mass) of work tells us? Three things, I would say. First, fiscal policy is back. it really is. The Washington Consensus does not exist anymore, at least in Washington. Be it because the multipliers are large, or because it has an impact on income distribution (and on economic efficiency); or again because public investment boosts growth, fiscal policy has a role to play both in dampening business cycle fluctuations and in facilitating stable and balanced long term growth. The fact that a large institution like the IMF has lent its support to this revival of consideration for fiscal policy, makes me hope that discussions about macroeconomic policy will be less ideological, even once the crisis will have passed.

The second thing I learn is that the IMF research department proves to be populated of true researchers, who continuously challenge and test their own views, and are not afraid of u-turns if their own research dictates them. I am sure it has always been the case. What is different from the past is that now they have a chief economist who seems more interested in understanding where the world goes than in preaching a doctrine.

The third remark is more problematic. If I write a paper saying that austerity will not be costly because multipliers are 0.5, and 2 years later retract my previous statement and argue that austerity is in fact self defeating, the impact on the world is zero. If the IMF does the same, during the two years huge suffering will be needlessly inflicted to masses of people. This poses a problem, as research by definition may be falsified. In the past an institution like the IMF would never have admitted a mistake. And we certainly do not want to go back there. Today they do admit the mistakes, but the suffering remains. The only way out to this problem is that the “new” IMF should learn to be cautious in its policy prescriptions, and always remember that any policy recommendation is bound to be sooner or later proven inappropriate by new data and research. We don’t live in a black and white world. Adopting a more prudent stance in dictating policies  would be wise (in Brussels as well, it goes without saying). And of course, the disconnect between the army and the general is also a problem.

Raise Fed Rates Now?

March 23, 2015 4 comments

A quick note on the US and the Fed. Pressure for rate rises never really stopped, but lately it has intensified. Today I read on the FT that James Bullard, Saint Louis Fed head, urges Janet Yellen to raise rates as soon as possible, to avoid “devastating asset bubbles”. Just a few months ago we learned that QE was dangerous because, once again through asset price inflation, it led to increasing inequality. Not to mention the inflationistas (thanks PK for the great name!) who since 2009 have been predicting Weimar-type inflation because of irresponsible Fed behaviour (a very similar pattern can be found in the EMU). Let’s play the game, for the sake of argument. After all, asset price inflation, and distortions in general are not unlikely in the current environment. So let’s assume that the Fed suddenly were convinced by its critics, and turned its policy stance to restrictive (hopefully this is just a thought experiment). I have two related questions to rate-raisers (the same two questions apply to QE opponents in the EMU):

  1. Do they think that private expenditure is healthy enough to grow and to sustain economic activity without the oxygen tent of monetary policy?
  2. If not, would they be willing to accept that monetary restriction is accompanied by a fiscal expansion?

I am afraid we all know the answer, at least to the second of these questions. Just yesterday, on Italian daily Il Corriere della Sera, Alberto Alesina and Francesco Giavazzi called for public expenditure cuts, invoking the confidence fairy and expansionary austerity (yes, you have read well. Check for yourself if you understand Italian. And check the date, it is 2015, not 2007) What Fed (and ECB) bashers tend to forget, in conclusion, is that central bankers are at the center of the stage, reluctantly, because they have to fill the void left, for different reasons, by fiscal policy.  Look at the fiscal stance for the US: 2015_03_Fiscal_Impulse_1 Fiscal impulse, the discretionary stance of the US government, was positive only in 2008-2009, and has been restrictive since then. In other words, while the US were experiencing the worse crisis since the 1930s, while recovery was sluggish and jobless, the US government was pushing the brake. We all know why: political blockage and systematic boycott, by one side of Congress, of each and every one of the measures proposed by the administration (that was a bit too timid, if I may say so). Whatever the reasons, the fact remains that fiscal policy was of very limited help during the crisis. What do Fed bashers have to say about this? What would have happened if, faced with procyclical fiscal policy, the Fed had not stepped in with QE? I am afraid their answer would once again turn around confidence fairies… The EMU is pretty much in the same situation. The following figure shows the cumulative fiscal impulse since 2008 for a number of countries: 2015_03_Fiscal_Impulse_2   The figure speaks for itself. With the exception of Japan (thanks Abenomics!) governments overall acted as brakes for the economy (Alesina and Giavazzi should look at the data for Italy, by the way). Central banks had to act in the thunderous silence of fiscal policy. So I repeat my question once again: who would be willing to exchange a normalization of monetary policy with a radical change in the fiscal stance? To conclude, yes, monetary policy has been very proactive (even Mario Draghi’s ECB); yes, this led us in unchartered lands, and we do not fully grasp what will be the long term effects of QEs and unconventional monetary policies; yes, some distortions are potentially dangerous.  But central bankers had no choice. We are in a liquidity trap, and the main tool to be used should be fiscal policy. Monetary policy could and should be normalized, if only fiscal policy would finally take the witness, and the burden to lift the economy out of its woes; if fiscal policy finally tackled the increasing inequality that is choking the economy. If fiscal policy did its job, in other words.

I don’t know why, but I have the feeling that Janet Yellen and Mario Draghi would not completely disagree.

Marginal Productivity? Think Again

May 13, 2014 3 comments

I am writing  a paper on inequality and the crisis,  for which I used Piketty and Saez ‘s World Top Income Database to try to understand whether the distributional effect changed over time. Unfortunately their data cover 2012 only for a handful of countries, among which are the United States; waiting for new data here is the evolution of income percentiles, including capital gains, from 2007 to 2009 (yellow bars), and from 2009 to 2012 (red bars):


The financial crisis of 2007-2008 mainly hit asset prices, thus having a major impact on the richest layers of the income distribution. In fact, the top 0.1% to 0.01% (a handful of people) lost more than 40% of their income in real terms, while average income of the bottom 90% dropped of around 10%. This was short-lasted, nevertheless, as the prolonged recession, and the jobless recovery that followed, quickly restored, and further deepened the distance between the rich on one side and the middle and lower classes on the other.  Since 2009 average income of the bottom 95% stagnated (for the bottom 90% it kept decreasing). Nothing really new, here. The iAGS 2014 report, to which I (marginally) contributed, reaches similar conclusions. But I thought it would be interesting to share it.

And while we are at it, here are the ratios of average income of those at the very top, with respect to income of the bottom 90% (from the same dataset):


The top 0.1%-0.01%, the same handful of people as before, has an average income that is 120 times the average income of the bottom 90%. This is also barely breaking news…

Now, as we all know, the traditional view on income distribution states that  factors of production are paid according to their contribution to the production process (their “marginal productivity”). Within this traditional view, the recent steep increase of inequality would be explained by skill-biased technical progress and increased competition in the globalized labor market: the entrance in the global labor market of low-skilled workers from emerging and developing economies lowered the average marginal productivity of labor, thus reducing its share of national income. Increasing inequality would then be an ineluctable process that policy is not supposed to address, if not at the price of reduced efficiency and growth. Is this a caricature? Not so much. in his recent Project Syndicate comment on Piketty, Kenneth Rogoff proposes once again the old tradeoff between inequality and growth that the crisis seemed to have buried once and for all (just look at the widely cited IMF discussion paper  by Ostry et al). The traditional view is alive and kicking, and those who oppose it are dangerous liberal extremists! After all, Rogoff tells us, the tide raises all boats…

The bottom line is that if a top executive makes on average 120 times the wage of his or her employee, well, this means that he or she is 120 times more productive. Rent seeking and political capture play no role in explaining the difference in pay. Circulez, il n’y a rien à voir…

Nothing new under the sky, I guess. But it is important, from time to time, to send out reminders.

Overheat to Raise Potential Growth?

March 19, 2014 4 comments

Update, March 20th: Speaking of ideological biases concerning inflation, Paul Krugman nails it, as usual.

On today’s Financial Times, Phillip Hildebrand gives yet another proof of unwarranted inflation terror. His argument is not new: In spite of the consensus on a weak recovery, the US economy may be close to its potential , so that further monetary stimulus would eventually be inflationary.

He then deflects (?) the objection that decreasing unemployment reflects decreasing labour force participation rather than new employment, by suggesting that it is hard to know how many of the 13 millions jobs missing are structural, i.e.not linked to the crisis. I think it is worth quoting him, because otherwise it would be hard to believe:

However, an increasingly vocal group of observers, including within the Fed, posits that more of the fall in the participation rate appears to have been structural than cyclical, and it was even predictable – the result of factors such as an ageing workforce and the effect of technology on jobs.

(the emphasis is mine). Now look at this figure, quickly produced from FRED data: Read more

Reduce Inequality to Fight Secular Stagnation

December 22, 2013 9 comments

Larry Summers’ IMF speech on secular stagnation partially shifted the attention from the crisis to the long run challenges facing advanced economies. I like to think of Summers’ point of as a conjectures that “in the long run we are all Keynesians”, as we face a permanent shortage of demand that may lead to a new normal made of hard choices between an unstable, debt-driven growth, and a quasi-depressed economy. A number of factors, from aging and demographics to slowing technical progress, may support the conjecture that globally we may be facing permanently higher levels of savings and lower levels of investment, leading to negative natural rates of interest. Surprisingly, another factor that had a major impact in the long-run compression of aggregate demand has been so far neglected: the steep and widespread increase of inequality. Reversing the trend towards increasing inequality would then become a crucial element in trying to escape secular stagnation.
