The action is on the asset side. Arjun Jayadev, Amanda Page-Hoongrajok and I have a new version of our state-local balance sheets paper up at Washington Center for Equitable Growth. It’s moderately improved from the version posted here a few months ago. I’ll have a blogpost up in the next day or two laying out the arguments in more detail. In the meantime, here’s the abstract:
This paper … makes two related arguments about the historical evolution of state-local debt ratios over the past 60 years. First, there is no consistent relationship between state and local budget deficits and changes in state and local government debt ratios. In particular, the 1980s saw a shift in state and local budgets toward surplus but nonetheless saw rising debt ratios. This rise in debt is fully explained by a faster pace of asset accumulation as a result of increased pressure to prefund future expenses… Second, budget imbalances at the state level are almost entirely accommodated on the asset side – both in the aggregate and cross-sectionally, larger state-local deficits are mainly associated with reduced net asset accumulation rather than with greater credit-market borrowing. …
What recovery? One of the central questions of U.S. macroeconomic policy right now is whether the slow growth of output and employment over the past decade are the result of supply-side factors like demographics and an exhaustion of new technologies, or whether — despite low measured unemployment — we are still well short of potential output. Later this month, I’ll have a paper out from the Roosevelt Institute making the case for the latter — that there is still substantial space for more expansionary policy. Some of my argument is anticipated by this post from Simon Wren-Lewis, which briefly lays out several ways in which a demand shortfall can have lasting effects on the economy’s productive capacity — discouraged workers leaving the labor force; reduced investment by business; and slower technical progress, because a slack economy is less favorable for innovation. He concludes: “There is no absence of ideas about how a great recession and a slow recovery could have lasting effects. If there is a problem, it is more that this simple conceptualization” — textbook model in which demand has only short-run effects — “has too great a grip on the way many people think.”
Along the same lines, here is a nice post from Adam Ozimek on the “mystery” of low wage growth. The mystery is that despite low unemployment, annual wage growth (as measured by the Employment Costs Index) has remained relatively low – 2 to 2.5 percent, rather than the 3 to 3.5 percent we’d expect based on historical patterns. (Ozimek doesn’t mention it, but total compensation growth — including benefits — is even lower, less than one percent for the year ending March 2017.) But, he points out, this historical relationship is based on measured unemployment; if we use the employment-population ratio instead, then recent wage gains are exactly where you’d expect historically. So the behavior of wages is another piece of evidence that the official unemployment rate is underestimating the degree of labor market slack, and that the fall in the employment-population ratio reflects — at least in part — weak demand rather than the inevitable result of worse demographics (or better video games).
The bondholders’ view of the world. Matthew Klein has a very enjoyable post at FT Alphaville taking apart the claim (from three prominent academics) that “The French Revolution began with the bankruptcy of the ancient regime.” This is, of course, supposed to illustrate the broader dangers of allowing sovereigns to stiff bondholders. But in fact, as Klein points out, the old regime did not default on in its loans — Louis XVI went to great lengths to avoid bankruptcy, precisely because he was afraid of the reaction of creditors. Further: It was the monarchy’s efforts to avoid default — highly unpopular taxes and spending cuts, then the calling of the Estates General to legitimate them — that set in motion the events that led to the Revolution. So the actual history — in which a government was overthrown after choosing austerity over bankruptcy — has been reversed 180 degrees to fit the prevailing myth of our times: that good and bad political outcomes all depend on the grace of the bond markets. As Klein says, this might seem like a small mistake, but it is deeply revealing about how ideology operates: “ Whoever introduced it must have been working off what he thought was common knowledge that didn’t need to be checked. There is no citation.”
Klein’s piece is also, in passing, a nice response to that silly Jacob Levy post which argues that democracy and popular sovereignty are myths and that modern states have always been ruled by the bondholders. Levy offers zero evidence for this claim; his post is of interest only as a signpost for where elite discourse may be heading.
Don’t blame Germany. Here is a very useful paper from Enno Schroeder and Oliver Piceck estimating the effects of an increase in German demand on other European economies. They use an input-output model to estimate the effect of an increase in spending in Germany on output and employment in each of the other 10 largest euro-area countries. One of the things I really like about this is that it does not depend on either econometrics or on any kind of optimization; rather, it is simply based on the observable data of the distribution of consumption spending and of intermediate inputs by various industries over different industries and countries, along with the fraction of household income consumed in various countries. This lets them answer the question: If spending in Germany increased by a certain amount and the composition of spending otherwise remained unchanged, what would the effect be on total spending in various European countries? Yes, they ignore possible price changes; but I don’t think it’s any less reasonable than the conventional approach, which goes to the opposite extreme and assumes prices are everything. And even if you want to add a price story, this approach gives you a useful baseline to build on.
Methodology aside, their results are interesting and a bit surprising: They find that the spillovers from Germany to other European countries are surprisingly small.
Our main finding suggests that if Germany’s final demand were to exogenously increase by one percent of GDP, then France, Italy, Spain, and Portugal’s GDP would grow by around a 0.1 percent, their unemployment rates would be reduced by a bit over 0.1 points, and their trade balances would improve by approximately 0.04 points. The spillover effects on Greece are significantly smaller.
Given how much larger Germany is than most of these countries, and how tightly integrated European economies are understood to be, these are surprisingly small numbers. It seems that a large proportion of German demand still falls on domestic goods, while imports come largely from the euro area — particularly, in the case of intermediate goods, from the former Warsaw Pact countries. As a result, even
if a German demand boom were to materialize, France, Greece, Italy, Spain, and Portugal would not benefit much in terms of growth and external adjustment. The real beneficiaries would be small neighbors (e.g. Austria and Luxembourg) and emerging economies in Eastern Europe that are well integrated into German supply chains (e.g. Czech Republic and Poland).
Of course, this doesn’t mean that more expansionary policy in Germany isn’t desirable for other reasons. (For one thing, German workers badly need raises.) But for the balance of payments problems in Southern Europe, other solutions are needed.
Today’s conventional is yesterday’s unconventional, and vice versa. Here is a useful NBER paper from Mark Carlson and Burcu Duygan-Bump on the conduct of monetary policy in the 1920s. As they point out, much of today’s “unconventional” policy apparatus was standard at that point, including large purchases of a range of securities — quantitative easing avant le lettre. As I’ve written on this blog before (here and here and here) discussion of monetary policy is made needlessly confusing by economists’ habit of treating the policy instrument as having a direct, immediate link to macroeconomic outcomes, which can be derived from first principles. Whereas anyone who reads even a little history of central banking finds that the ultimate goal of control over the pace of credit expansion has been pursued by a wide range of instruments and intermediate targets in different settings.
Also on the mechanics of monetary policy, I liked these twoposts from the New York Fed’s Liberty Street Economics blog. They do something which should be standard but isn’t — walk through step by step the balance sheet changes associated with various central bank policy shifts. In my experience, teaching monetary policy in terms of balance sheet changes is much more straightforward than with the supply-and-demand diagrams that are the basic analytic tool in most textbooks. The curves at best are metaphors; the balance sheets tell you what actually happens.
