This paper reports estimates of monetary policy reaction functions for two sets of countries: the G3 (Germany, Japan and the United States) and the E3 (France, Italy and the United Kingdom). It finds that since 1979 each of the G3 central banks has pursued an implicit form of inflation...

We develop and estimate a structural model of inflation that allows for a fraction of firms that use a backward looking rule to set prices. The model nests the purely forward looking New Keynesian Phillips curve as a particular case. We use measures of marginal cost as the relevant determinant...

We analyse the implications for the dynamics of capital accumulation of market power and endogenous demand elasticities, in an environment in which the latter are affected by the number of competitors in each industry. In equilibrium the interest rate increases as capital accumulates, even...

In this Paper we present a simple, theory-based measure of the variations in aggregate economic efficiency that is based on the difference between the marginal product of labour and the household’s consumption/leisure trade-off. We show that this indicator corresponds to the inverse of the...

The New Keynesian framework has emerged as the workhorse for the analysis of monetary policy and its implications for inflation, economic fluctuations, and welfare. It is the backbone of the new generation of medium-scale models under development at major central banks and international policy...

Recent evidence suggests that consumption rises in response to an increase in government spending. That finding cannot be easily reconciled with existing optimizing business cycle models. We extend the standard new Keynesian model to allow for the presence of rule-of-thumb consumers. We show how...

We characterize the macroeconomic performance of a set of industrialized economies in the aftermath of the oil price shocks of the 1970s and of the last decade, focusing on the differences across episodes. We examine four different hypotheses for the mild effects on inflation and economic...

The remarkable decline in macroeconomic volatility experienced by the U.S. economy since the mid-80s (the so-called Great Moderation) has been accompanied by large changes in the patterns of comovements among output, hours and labor productivity. Those changes are reflected in both conditional...
