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.



Marginal Productivity? Think Again

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.
