The massive expansion of central-bank balance sheets in response to recent crises raises important questions about the effects of such "quantitative easing" policies, both their effects on financial conditions and on aggregate demand (the intended effects of the policies), and their possible...

This paper reconsiders the degree to which macroeconomic stabilization is possible when the zero lower bound is a relevant constraint on the effectiveness of conventional monetary policy, under an assumption of bounded rationality. In particular, we reconsider the potential role of...

Erceg et al. (2000) show that when both wages and prices are sticky, maximization of expected utility is equivalent to minimizing a loss function with three terms, involving measures of the variability of wage inflation, price inflation and the output gap respectively. Here we generalize their...

This paper presents a model in which economic crises have positive effects on welfare. Periods of very high inflation create the incentive for the resolution of social conflict and thus facilitate the introduction of economic reforms and the achievement of higher levels of welfare. Policies to...

When a stabilization has significant distributional implications (as in the case of tax increases to eliminate a large budget deficit) different socio-economic groups will attempt to shift the burden of stabilization onto other groups. The process leading to a stabilization becomes a "war of...

Existing models of contagious currency crises are summarized and surveyed, and it is argued that more weight should be put on political factors. Towards this end, the concept of political contagion introduced, whereby contagion in speculative attacks across currencies arises solely because of...

High interest rates to defend the exchange rate signal that a government is committed to fixed exchange rates, but may also signal weak fundamentals. We test the effectiveness of the interest rate defense by disaggregating into the effects on future interest rates differentials, expectations of...

Standard models of policy credibility. defined as the expectation that an announced policy will be carried out. emphasize the preferences of the policymaker (his "type") and the role of policies in signaling type. Whether a policy is carried out. however. should also reflect the state of the...
