This paper shows that the value function describing efficient risk sharing with limited commitment is not necessarily differentiable everywhere. We link differentiability of the value function to history dependence of efficient allocations and provide sufficient conditions for both properties.

Limited participation models explain a short-run liquidity effect as arising from the redistribution of income from non-participants in the bond market to participants in the bond market. However, these models also imply that the liquidity effect is smaller the larger is long-run money growth....

This paper examines the allocation of heterogeneous workers across sectors of an economy in which workers are able to direct their search towards particular firms. We find that search frictions, in addition to causing unemployment, may result in an inefficient allocation of labor. This result...

This paper shows that counter-cyclical and counter-inflation monetary policy rules are crucial for monetary business cycle models to match the observed negative (or weak) correlation of the growth rate of money and output, inflation, and the interest rate at business cycle frequencies, which...

The U.S. trade deficit with China exceeded $200 billion in 2005. Many blame these imbalances on the value of the renminbi. This paper investigates how an appreciation of the RMB would affect the U.S. trade balance with China. Johansen MLE and dynamic OLS results indicate that the long run real...

This paper introduces a signalling model of conspicuous consumption in the context of an endogenous growth model. Agents purchase luxury goods to signal their social status. 'Invidious Comparison' takes place when rich agents successfully identify themselves, whereas 'Pecuniary Emulation' takes...
