Endogenous business cycles and the dynamics of output, hours, and consumption
This paper studies the business-cycle fluctuations predicted by a two-sector endogenous-business-cycle model with sector-specific external increasing returns to scale. It focuses on aspects of actual fluctuations that have been identified both as defining features of the business cycle and as ones that standard real-business-cycle models cannot explain: the autocorrelation function of output growth, the impulse response function of output to demand shocks, and the forecastable movements of output, hours, and consumption. For empirically realistic calibrations of the degree of sector-specific ...

Backward-looking interest-rate rules, interest-rate smoothing, and macroeconomic instability
The existing literature on the stabilizing properties of interest-rate feedback rules has stressed the perils of linking interest rates to forecasts of future inflation. Such rules have been found to give rise to aggregate fluctuations due to self-fulfilling expectations. In response to this concern, a growing literature has focused on the stabilizing properties of interest-rate rules whereby the central bank responds to a measure of past inflation. The consensus view that has emerged is that backward-looking rules contribute to protecting the economy from embarking on expectations-driven ...

Policy implications of the New Keynesian Phillips curve
This article surveys recent advancements in the theory of optimal monetary policy in models with a New Keynesian Phillips curve. It identifies four policy implications. First, near price stability is optimal. Second, simple interest rate feedback rules that respond aggressively to price inflation deliver near-optimal equilibrium allocations. Third, interest rate rules that respond to deviations of output from trend may carry significant welfare costs. Fourth, the zero bound on nominal interest rates does not appear to be a significant obstacle for the actual implementation of low and stable ...
