The mystery of productivity: what mystery?

Another old one. Trying to catch up after the Thanksgiving break. Mainstream economists seem always puzzled by productivity. It is the source of growth and a mystery (Helpman has a book titled The Mystery of Economic Growth). They refer to trends in productivity as puzzles, in particular the slowdown after 1973.
 
Alan Blinder: reminds us that after the surge in productivity growth, that for a while at least was referred to as the New Economy, associated to information technologies, has collapsed to even lower levels than the 1973-1995 period. He is, as a good mainstream author, quite puzzled. In his words, "quite surprisingly and still somewhat mysteriously, productivity growth plummeted [after 1973]... We are all in the dark."

In Jeon and Vernengo (2008) we suggest that labor productivity is endogenous, explained essentially by the expansion of demand, and old idea, implicit in Adam Smith's vent for surplus, and part of a well established empirical regularity, the so-called Kaldor-Verdoorn Law. In other words, it is the weak recovery, caused by a contractionary fiscal stance, and the slow pace of private spending growth as employment increases, that explains the poor performance of productivity. In this sense, the causes are considerably simpler, connected to macro policy, rather than the long-term pessimism of Gordon and Summers, which now talk about secular stagnation (see also this book).

Perhaps the more interesting stuff in Blinder's piece is his discussion of what the 'serious people' in the mainstream consider the natural rate to be. He says:
"the 'central tendencies' in the Federal Open Market Committee’s latest published forecasts range from 5.2% to 5.5% for the 'full-employment' unemployment rate, and from 2% to 2.3% for the potential GDP trend."
Note that Blinder also thought that the speed limit was around 2% back in the late 1990s (here his debate with Bluestone and Harrison). And yes he is a Keynesian (a New Keynesian). With friends like this...

  1. Hi Matias, Your paper that you link to has the following footnote:

    11. This does not imply that the Clinton boom was devoid of problems. First,the recovery did little to improve income distribution,and it was based,to a great extent,on the “dot.com”bubble. For a critique of the Clinton years,see Robert Pollin (2003)

    Is the Robert Pollin (2003) critique stuffed in a fancy journal somewhere or is it available online (you know, on one of the FREE sites)? If so, can you please link?

    1. Contours of descent is a book, but some parts are similar to his paper Anatomy of Clintonomics available here http://newleftreview.org/II/3/robert-pollin-anatomy-of-clintonomics

  2. I tend to share your view on the endogenous nature of productivity. I actually think that Blinder, to a large extent actually agrees with you. Check out what Blinder had to say more recently here, which I think is consistent with your view:

    "I have saved the best option, in terms of likely effectiveness, for closing the gap between productivity and wages for last: speeding up the rate of economic growth and tightening labor markets. It’s not a panacea, to be sure, but running a high-pressure economy is the surest way to boost the demand for labor—often for labor at all skill levels. And steep competition for labor is probably the surest route to higher real wages; firms will pay more for labor when they have to. Lately, with so much slack in labor markets, they haven’t had to."

    On a related point, Robert Gordon argues that productivity may no longer be procyclical.

  3. "The record clearly shows that manhour productivity is depressed by low levels of utilization, and that periods of movement toward full employment yield considerably above-average productivity gains." -- Arthur Okun, 1962

A few brief comments on Brexit and the postmortem of the European Union

Another end of the world is possible
There will be a lot of postmortems for the European Union (EU) after Brexit. Many will suggest that this was a victory against the neoliberal policies of the European Union. See, for example, the first three paragraphs of Paul Mason's column here. And it is true, large contingents of working class people, that have suffered with 'free-market' economics, voted for leaving the union. The union, rightly or wrongly, has been seen as undemocratic and responsible for the economics woes of Europe.

The problem is that while it is true that the EU leaders have been part of the problem and have pursued the neoliberal policies within the framework of the union, sometimes with treaties like the Fiscal Compact, it is far from clear that Brexit and the possible demise of the union, if the fever spreads to France, Germany and other countries with their populations demanding their own referenda, will lead to the abandonment of neoliberal policies.

A brief note on Venezuela and the turn to the right in Latin America

So besides the coup in Brazil (which was all but confirmed by the last revelations, if you had any doubts), and the electoral victory of Macri in Argentina, the crisis in Venezuela is reaching a critical level, and it would not be surprising if the Maduro administration is recalled, even though right now the referendum is not scheduled yet.

The economy in Venezuela has collapsed (GDP has fallen by about 14% or so in the last two years), inflation has accelerated (to three digit levels; 450% or so according to the IMF), there are shortages of essential goods, recurrent energy blackouts, and all of these aggravated by persistent violence. Contrary to what the press suggests, these events are not new or specific to left of center governments. Similar events occurred in the late 1980s, in the infamous Caracazo, when the fall in oil prices caused an external crisis, inflation, and food shortages, which eventually, after the announcement of a neoliberal economic package that included the i…
