A number of authors have attemted to test whether the U.S. economy is in a determinate or an indeterminate equilibrium. We argue that to answer this question, one must be impose a priori restrictions on lag length that cannot be tested. We provide examples of two economic models. Model 1...

This paper develops a model with multiple steady states (low tax and unemployment rate versus high tax and unemployment rate) in which equilibrium selection is not conditioned on a sunspot variable. Instead, large enough shocks initiate unavoidable transitions from one regime to the other. The...

We study identiÞcation in a class of three-equation monetary models. We argue that these models are typically not identiÞed. For any given exactly identiffed model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...

This paper analyzes the efficiency of risk-taking decisions in an economy that is prone to systemic risk, captured by financial amplification effects that occur in response to strong adverse shocks. It shows that decentralized agents who have unconstrained access to a complete set of Arrow...

This paper presents evidence for structural differences in economic growth dynamics between the current EU and the central- and eastern European accession countries. Two important results emerge from the analysis. First, accession countries have posted higher average growth and wider output...

After the switch to a floating exchange rate in 1973, the Swiss National Bank at first adopted annual monetary targets and in the 1990s shifted to a medium-term targeting strategy. In this paper I review the SNBu0092s internal policy analysis, an aspect of Swiss monetary targeting that has...
