We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

Blanchard (2005) suggested that active interest rate policy might induce unstable dynamics in highly-indebted economies. We examine this in a dynamic general equilibrium model where Calvo-type price rigidities provide a rationale for inflation stabilization. Unstable dynamics can occur when the...

We study interactions between monetary policy, which sets nominal interest rates, and fiscal policy, which levies distortionary income taxes to finance public goods, in a standard, sticky-price economy with monopolistic competition. Policymakers' inability to commit in advance to future policies...

Why do firms delegate job design decisions to workers, and what are the implications of such delegation? We develop a private-information based theory of delegation, where delegation enables high-ability workers to signal their ability by choosing difficult tasks. Such signalling provides a more...

Inflation target regimes (like those of Canada, Finland, New Zealand, Sweden and the United Kingdom) are interpreted as having explicit inflation targets and implicit output/unemployment targets. Without output/unemployment persistence, delegation of monetary policy to a discretionary...

We examine to what extent variants of inflation-forecast targeting can avoid stabilization bias, incorporate history-dependence, and achieve determinacy of equilibrium, so as to reproduce a socially optimal equilibrium. We also evaluate these variants in terms of the transparency of the...

Empirical fiscal policy reaction functions based on ex-post data cannot be said to describe fiscal policymakers intentions because they utilise data which did not exist when their decisions were made. A characterisation of what fiscal policy makers were trying to do requires real time data. This...

This Paper reviews the distinction between the timeless perspective and discretionary modes of monetary policymaking, the former representing rule-based policy as recently formalized by Woodford (1999b). In models with forward-looking expectations there is typically a second inefficiency from...
