This paper looks at theoretical and empirical issues associated with the operation of fiscal stabilizers within an economy. It argues that such stabilizers operate most effectively at a national, rather than local, level. As differing cycles across regions tend to offset each other for the...

The paper surveys the types of models producing multiple equilibria in financial markets. It argues that such models are consistent with observed phenomena, such as the greater volatility of financial asset prices than of macroeconomic fundamentals. Alternative explanations are compared with the...

Several concepts of contagion are distinguished. It is argued that only models that admit of multiple equilibria are capable of producing true contagion. A simple balance of payments model is presented to illustrate that phenomenon, and some back-of-the-envelope calculations assess its relevance...

Evaluation of policy rules using empirical macroeconomic models is usually done on the assumption that the rules are perfectly credible. However, there are usually circumstances that cause the authorities to abandon any given rule. The public's expectations reflect this possibility. In the...

The “hollowing-out,” or “two poles” hypothesis is tested in the context of a Markov chain model of exchange rate transitions. In particular, two versions of the hypothesis—that hard pegs are an absorbing state, or that fixes and floats form a closed set, with no transitions to...

International macroeconomic policy coordination is generally considered to be made less likely—and less profitable—by the presence of uncertainty about how the economy works. The present paper provides a counter-example, in which increased uncertainty about portfolio preference of investors...

Standard models of policy credibility, defined as the expectation that an announced policy will be carried out, emphasize the preferences of the policymaker, and the role of tough policies in signalling toughness and raising credibility. Whether a policy is carried out, however, will also...
