On China and Jobs

It is true that whenever the economy grows trade deficits tend to become larger, and the United States, which has had persistent deficits since the early 1980s, is particularly prone to those. Dean Baker has been the most vocal defender of a weak dollar (mostly as measure to boost local manufacturing jobs, since a depreciated currency protects local production; here for example a recent piece). Krugman too has recently argued for a more depreciated dollar and also for trade restrictions against China (see here for a recent one).

In all fairness, I have a few concerns with these line of thought, and not because I am (or ever was) a "free trader", like Krugman (by the way Free Trade is a terrible misnomer and there are serious problems with the conventional arguments for it; theme for another post, I guess).

First, in the case of China, the exchange rate has appreciated a lot since the crisis as can be seen in the graph below (Data from the Economist Intelligence Unit).
Further, when measured by changes in wages (labor costs) the real appreciation since 2007 has been of around 27%, 10% more than when measured by prices, since real wages grow relatively fast in China. Further, China has grown since 2007 at an average of 10.5% per year. In other words, China is growing and revaluing its currency; not sure what more can be expected on that front. Blaming China for lack of fiscal stimulus in the US seems, not just futile, but wrongheaded.

Another important point often missed in these discussions of the exchange rate is that a depreciated currency, everything else constant (economists do like a ceteris paribus condition) implies lower real wages, since imported goods tend to be part of the workers' consumption basket. Hence, if you favor a depreciated dollar, but tend to be for workers (which are getting to bear the brunt of this crisis, as is always the case), then compensating measures are needed to increase real wages without reducing competitiveness (other costs must be reduced, or profit margins would have to be squeezed; that's just the algebra).

Finally, my perennial question, raised before here, so if US deficits are larger, but we give the Chinese dollars, and they hold dollar denominated assets, what's the downside again?

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…
