The Unassuming Economist

From a new IMF working paper by Andrew Berg, Edward Buffie, and Luis-Felipe Zanna:

“Advances in artificial intelligence and robotics may be leading to a new industrial revolution. This paper presents a model with the minimum necessary features to analyze the implications for inequality and output. Two assumptions are key: “robot” capital is distinct from traditional capital in its degree of substitutability with human labor; and only capitalists and skilled workers save. We analyze a range of variants that reflect widely different views of how automation may transform the labor market. Our main results are surprisingly robust: automation is good for growth and bad for equality; in the benchmark model real wages fall in the short run and eventually rise, but “eventually” can easily take generations.”

“Figure 3 plots the transition paths [when robots and labor are perfect vs. imperfect substitutes, when all other parameters take their base case bales.] Perfect substitution of robot for human labor delivers perpetual growth. But the rich become richer and the poor poorer with every passing year. In the long run, the real wage decreases 13.4% while capitalists’ income rises without limit.”

Economic growth has traditionally moved in tandem with pollution. But can countries break this link and manage to grow while lowering pollution?

Our research, based on joint work with Gail Cohen and Ricardo Marto, shows that yes, progress is being made. Our evidence is clear: advanced economies are starting to show signs of decoupling—increasing growth while reducing pollution—but emerging market economies not yet.

The chart summarizes our evidence on the link between the trend (long-run relationship) in greenhouse gas (GHG) emissions and the trend in incomes. Our analysis covers the world’s top twenty largest GHG emitters from 1990 to the present. Over this time, incomes have grown—the trend is positive—despite dips due to occasional recessions and financial crises. But what has happened to trend emissions?

The bars in the chart show the percent increase in trend emissions for every 1 percent increase in trend incomes—economists refer to such estimates as elasticities. Look first at the three cases on the far right of the chart—Germany, the United Kingdom, and France. For this group the elasticity estimates are negative: emissions have fallen despite the increase in incomes. These countries have achieved decoupling of emissions and output. Our results show that this is due both to active policies by these countries aimed at decarbonizing their economies as well as the structural transformation of their economies towards a greater role for services.

A new IMF working paper “explores regional differences to shed light on drivers of participation rates at the state and metropolitan area levels. It documents a broad-based decline, especially pronounced outside metropolitan areas. Using novel measures of local vulnerability to trade and technology it finds that metropolitan areas with higher exposures to routinization and offshoring experienced larger drops in participation in 2000-2016. Thus, areas with different occupational mixes can experience divergent labor market trajectories as a result of trade and technology.”

A new report by Lawrence Mishel says that “Uber, and gig work more broadly, [does not] represent the future of work.” “Uber drivers earn low wages and compensation and the total hours and compensation in the gig economy represent a very small share of total hours and compensation in the overall economy. These findings—and the fact that many Uber and other workers who provide personal services via a digital platform do so on a part-time basis primarily as a way to earn supplementary income—argue for a change in perspective. There has been much hype around Uber and the gig economy. But in our assessment, in any conference on the future of work, Uber and the gig economy deserve at most a workshop, not a plenary.”
