between social security and Medicaid. As a result of these interactions, we find that the US social security significantly lowers the cost of financing Medicaid and other welfare programs for the elderly as it reduces the fraction of households who choose to rely on means-tested transfers to...

We measure asymmetries in the distribution of bond returns and exchange rates and test their statistical significance. Asymmetries are sizable when measured by the coefficient of skewness, a measure that is highly affected by outliers. In contrast, robustly measured asymmetries to outliers often...

This paper uses Japanese data to investigate the relationship between monetary policy and the yield curve. We find that the response of the yield curve depends in an important way on the maintained hypothesis about how monetary policy affects the economy. Under the liquidity effect maintained...

The distinguishing feature of natural-catastrophe risk is claimed to be aggregate risk. Because such risk is encompassed in the general competitive model, it seems to pose no new theoretical challenge. However, that model has markets contingent on exogenous events, while the actual economy seems...

This paper is motivated by empirical observations on the comovements of currency velocity, inflation, and the relative size of the credit services sector. We document these comovements and incorporate into a monetary growth model a credit services sector that provides services that help people...

We consider the nature of optimal cyclical monetary policy in three different stochastic models with various shocks. The first is a pure liquidity effect model, the second is a cost of changing prices model, and the third is an optimal seignorage model. In each case we solve for the optimal...

In aggregate unadjusted data, measured Solow residuals exhibit large seasonal variations. Total Factor Productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of ?24 percent. This paper considers two potential...

Barksy-Miron [1989] find that the postwar U.S. economy exhibits a regular seasonal cycle, as well as the business cycle phenomenon. Are these findings consistent with current equilibrium business cycle theories as surveyed by Prescott [1986]? We consider a dynamic, stochastic equilibrium...
