Investment in infrastructure is a no brainer

NYTimes comic strip that gets economics right, which is more than you can say about most pundits and a good chunk of the profession.


  1. Infrastructure investment as a way out of recessions are a bad idea. First, many such projects take years to plan and get started, by which time the recession may be over. Second, interest rates are low at least to some extent for an artificial reason: central banks have cut those rates.

    For an optimum allocation of resources, prices (including the price of borrowed money) should be at free market rates.

    1. Hi Ralph, thanks for the comment. First, I'm very skeptical of the argument that there are no ready made projects. Look at the experience of the WPA in the 1930s. And the engineers have had a report on all the upgrades needed for infrastructure for years (US gets a D grade).

      On the interest rate, there is nothing artificial about central banks keeping them low. That's what happens in a world where a natural rate of interest does not exist. Note that your comment is about what interest rates "should be" in a free market, but alas that's not what they are.

    2. I didn’t actually say there were “no ready made projects”. I said “many such projects take years to plan and get started”. That’s certainly true of the projects that featured in your cartoon: bridges, sewage systems, transit systems, and school buildings.

      Next , 90% of the unemployed do not have skills relevant to the latter projects. And just in case anyone wants to claim there are loads of construction workers unemployed as a result of the downturn on house construction caused by the crunch, that is not true: the evidence is that former construction workers have found no more difficulty getting alternative work than those losing jobs in other sectors.

      Next, why skew the economy towards infrastructure projects in a recession? I.e. why not boost ALL TYPES of economic activity? That way, far better use will be made of the variety of skills amongst the unemployed. One might as well skew the economy towards farming, car production, restaurants, you name it.

      Re interest rates, the RELEVANT rate is the rate that will apply over the lifetime of the capital investment: 20 – 50 years? And the crunch has had no discernible effect on the 30 year rate. The only major change in that rate since WWII was the big spike during the 1970-80 inflationary episode. But that was not so much a rise in the REAL or inflation adjusted rate: it was a rise in the nominal rate to take account of expected inflation.

    3. There is one simple reason, it is needed, and it's good for growth. The notion that skills are not available is not credible. There are lots of simple jobs that require little skills, and for those that do need, you can always get immigrants. And yes this has multiplier effects, so overall is good.

      And on the interest rate the long run interest (which is not 50 years, longest bonds are 30, and nobody thinks that bonds of 10 years are not relevant for investment) are influenced indirectly with the base rate and directly (QE is basically that) by the Fed. THat's why they are low.

      During the Depression Eccles guaranteed that long term interest on government bonds should not be above 2.5%. I would rather do what Jamie Galbraith suggests and get an Infrastructure bank with public money, but that's not essential.

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…
