This paper proposes a structural approach to growth modeling relying on random return scale. An RBC-like model in which return to scale may be strictly increasing or decreasing depending on shocks is explicitly derived. We show that relevant component of usual macroeconomic models (including...

Evidence from English real wages and real land rents for the period 1500-1800 are used to evaluate the impact of temperature and precipitations on under-developed economies. Estimating key parameters of an AK-growth model, we extract Total Factor Productivity (TFP hereafter) shocks and estimate...

This paper examines if taking into account changes in the number of producers, or equivalently changes in the product variety space over the business cycle, helps to understand and replicate international business cycle facts. To this end, we develop a two-country model in which the economy is...

A chief goal of the Pigou cycle literature is to generate a boom in response to news of a future increase in productivity, and a bust if this improvement does not in fact take place. We nd that monetary policy can generate Pigou cycles in a two sector model with durables and non-durables, and...

This paper is an attempt to explain differences in economic performance between a subset of OECD countries. We classify countries in terms of their degree of rigidity in the labor market, and use a matching model with labor/leisure choice, bargaining frictions, and labor income taxation to...

This paper shows that a model which combines sticky prices and sticky wages with investment in the cash-in-advance constraint generates business cycle dynamics consistent with empirical evidence. The model reproduces the responses of the key macroeconomic variables to technology and money supply...

This paper shows that in a monetary union the interest rate rule of the Central Bank should react to the in°ation rate of the Harmonized Index of Consumption Price (HICP) rather than to the inflation rate of the Welfare-Based Consumption Price (WBCP). In a two{country general equilibrium model...

We investigate the design of incentives for quality provision in a dynamic regulation setting in which maintenance efforts and quality shocks have durable effects. When the regulator contracts with a sequence of agents, asymmetries of information can lead to overprovision of quality, reflecting...

In this paper we study jointly optimal ¯scal and monetary policies in a small open economy framework with capital and sticky prices. We consider the case of distor- tionary taxes on labor and capital, and no public debt. As in a closed economy set{up, in the steady state, the optimal in°ation...

Cet article propose une extension du cadre de travail théorique proposée par Bilbiie, Ghironi et Melitz [2007] en économie ouverte afin d'étudier les effets de la politique monétaire sur marges intensives et extensives sur l'activité économique. Deux régimes de politique monétaire sont...
