Does monetizing a deficit always result in a higher rate of inflation than bond financing the same deficit? T. J. Sargent and N. Wallace (1981) produced conditions under which the answer was negative ('unpleasant monetarist arithmetic'). Subsequent authors have challenged the empirical validity...

In this paper, we expand previous models with banks and money and explore the consequences of seasonals in the banking system. We find that, when bank failures occur, not all of them have associated large output losses and currency premiums exist. We show that the most important sources of...

Existing models of banking panics contain no role for monetary factors and fail to explain why some banking systems experienced panics while others did not. A monetary model is constructed, where seasonal variations in the demand for liquidity and credit play a critical role in generating...

Three economic environments are reviewed and, in each, organizations play an essential role. For an adve rse selection insurance economy, the authors find that when mutual in surance arrangements are permitted, an equilibrium necessarily exists and is optimal. This example, and two others,...

A choice-theoretic, cash-in-advance model is constructed to examine foreign-exchange controls. While foreign-exchange controls improve the trade balance and the balance-of-payments (or exchange rate) they reduce welfare for a distortion-free, small, open economy. This is because foreign-exchange...

This analysis investigates modeling the natural rate of unemployment in settings wh ere labor's utilization has some lumpy aspect to it. Specifically, th e introduction of various nonconvexities into tastes and technology l ead to unemployment in general equilibrium. Equilibria can emerge whe re...
