To construct a business cycle model consistent with the observed behavior of asset prices, and study the effect of shocks to aggregate uncertainty, I introduce a small, time-varying risk of economic disaster in a standard real business cycle model. The paper establishes two simple theoretical...

We study a competitive credit market in which lenders with partial knowledge of loan repayment use one of three decision criteria - maximization of expected utility, maximin, or minimax regret - to make lending decisions. Lenders allocate endowments between loans and a safe asset, while...

Uncertainty is a ubiquitous concern emphasized by policymakers. We study how uncertainty affects decision-making by the Federal Open Market Committee (FOMC). We distinguish between the notion of Fed-managed uncertainty vis-a-vis uncertainty that emanates from within the economy and which the Fed...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

In this paper I focus on two specific hazard areas in the transition from Stage Two to Stage Three of European economic and monetary union (EMU), as well as on some key problems of Stage Three that EMU's monetary and fiscal structures appear ill-prepared to handle. The transitional hazards are...

This paper presents a theoretical and empirical investigation into timing relationships between variables within and across industrialized countries. In the analysis we highlight the two polar cases of completely closed and open economies and draw some implications for timing between monetary...

In dealing with the expectationists' arguments, I will divide them (somewhat artificially) into two groups. Arguments in the first group, which I call "present disaster" arguments, allege that econometric models err by understating the reaction of inflationary expectations. For example, it is...
