Dans cet article, nous présentons un survol de la littérature macroéconomique sur la taxation optimale. En premier lieu, nous présentons un modèle très simple à agent représentatif afin de démontrer le résultat principal de cette littérature concernant le taux de taxation sur le...

This working paper describes two well-known approaches to finding an approximate solution to a real business cycle model: solving a linear-quadratic approximation to a social planning problem; and solving a linearized version of the equilibrium conditions of the model.

We survey the existing work on the cross-country differences in the transmission of European monetary policy. We find that prior work, focusing on macroeconomic data, does not clearly answer the question posed in the title and offer some explanations for the ambiguity.

This paper documents and discusses a dramatic change in the cyclical behavior of aggregate hours worked by individuals with a college degree (skilled workers) since the mid-1980’s. Using the CPS outgoing rotation data set for the period 1979:1-2003:4, we find that the volatility of aggregate...

This paper surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...

The labor search and matching model plays a growing role in macroeconomic analysis. This paper provides a critical, selective survey of the literature. Four fundamental questions are explored: how are unemployment, job vacancies, and employment determined as equilibrium phenomena? What...

This paper investigates the effects of introducing imperfect competition in an international business cycle model. We provide some international evidence on markups and analyze the implicactions of increasing returns to scale and monopolistic competition for the effects and the international...

One of the main topics of macroeconomics analysis is to assess the causes and transmission of business cycles. In order to address this issue, macroeconomists have analysed the response of output to different types of shocks. However, since a shock is by definition an unobserved variable, there...

The Real Business Cycle (RBC) research program has grown spectacularly over the last decade, as its concepts and methods have diffused into mainstream macroeconomics. Yet, there is increasing skepticism that technology shocks are a major source of business fluctuations. This chapter exposits the...

Multi-countru models have not been very successful in replicating features of the international transmission of business cycles. Standard models predict cross-country correlations of output and consumption which are respectively too low and loo high. In this paper, we built a multi-country model...
