Creator: Kocherlakota, Narayana Rao, 1963- Series: Lucas expectations anniversary conference Abstract:
There were three important changes in the United States economy during the 1980s. First, from 1982-90, the decade featured the longest consecutive stretch of positive quarterly output growth in United States history. Second, wage inequality expanded greatly as the wages of highly skilled workers grew markedly faster than the wages of less skilled workers (Katz and Murphy (1992)). Finally, consumption inequality also expanded as the consumption of highly skilled workers grew faster than that of less skilled workers (Attanasio and Davis (1994)). This paper argues that these three aspects of the United States economic experience can be interpreted as being part of an efficient response to a macroeconomic shock given the existence of a particular technological impediment to full insurance. I examine the properties of efficient allocations of risk in an economic environment in which the outside enforcement of risksharing arrangements is infinitely costly. In these allocations, relative productivity movements have effects on both the current and future distribution of consumption across individuals. If preferences over consumption and leisure are nonhomothetic, these changes in the allocation of consumption will generate persistent cycles in aggregate output that do not occur in efficient allocations when enforcement is costless.

We report estimates of the dynamic effects of a technology shock, and then use these to estimate the parameters of a dynamic general equilibrium model with money. We find: (i) a positive technology shock drives up hours worked, consumption, investment and output; (ii) the positive response of hours worked reflects that the Fed has in practice accommodated technology shocks; (iii) model parameter values and functional forms that match the response of macroeconomic variables to monetary policy shocks also work well for technology shocks; (iv) while technology shocks account for a large fraction of the lower frequency component of economic fluctuations, they account for only a small part of the business cycle component of fluctuations.
