Empirical studies reveal that monetary policy shocks generate long-lasting effects on real GDP, countercyclical real wages before World War II and procyclical real wages afterwards. In this paper, we construct a dynamic general equilibrium model to explain the observed output persistence and the...

Multi-country models have not been very successful in replicating important features of the international transmission of business cycles. This paper extends previous work by introducing multiple sectors and traded intermediate inputs. Trade in intermediate goods represents approximately 60% of...

Using aggregate US and Canadian data, this paper examines the implications for the empirical assessment of market structure and exogeneity of productivity shocks of correcting the Solow residual for variation in capacity utilization. In contrast to most studies, not accounting for capacity...

We analyze a stochastic general equilibrium model which incorporates three different types of government expenditure. We calibrate the model and simulate it under the hypotheses of divisible and indivisible labor supply. Our results indicate that the addition of government expenditure shocks to...

We estimate an optimization-based model with sticky prices alone (SP model) and one that combines nominal and real rigidities in the form of costly price and labor adjustments (NRR model) over the U.S. postwar time period. We then compare their ability to generate persistent, positive, responses...

We present and assess a procedure to evaluate dynamic, stochastic, general equilibrium macroeconomic models when agents in the economy use an information set superior to that used by researchers. <P> Cette étude présente et documente une procédure d'évaluation de modèles macroéconomiques...</p>

Business cycle statistics differ widely across countries, especially for trade-related variables. Part of these variations relates to the size of the economies and to their distance from each other. This paper asks whether a three-country model is able to display the marked diversity of business...

In this paper, we test whether labor-hoarding environments with basic and augmented laws of motion provide an adequate explanation for observed business cycle dynamics. The basic law of motion assumes that the information set used by economic agents to forecast future forcing variables includes...

Economic fluctuations are much stronger in developing countries than in the United States. Yet, while a large literature debates what constitutes a reasonable estimate of the welfare cost of business cycles in the US, it remains an open question how large that cost is in developing countries....

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...
