We use laboratory experiments with human subjects to test the relevance of di-fferent inflation targeting regimes. In particular and within the standard New Keynesian model, we evaluate to what extent communication of the inflation target is relevant to the success of inflation targeting. We...

The dramatic decline in inflation across the world over the last 20 years has been largely credited to improved monetary policy. The universal nature of the phenomenon and its simultaneity with globalization however indicate that there might also be a "real" side to it. We build a model based on...

In the light of the economically rational expectation theory, this article shows how an expert chooses an optimal oil price forecast function given that information is costly. In this framework we propose an expectational process which nests all processes considered in the literature. By...

This paper relaxes a fundamental hypothesis commonly accepted in the expectation formation literature: expectations are, unchangingly, either rational or generated by one of the three simple extrapolative, regressive or adaptive processes. Using expectations survey data provided by Consensus...

In the aftermath of the sovereign debt criss, open-market interventions prevailed within the central bank's policy answers known under the label unconventional monetary policy measures. During interwar period, France was an isolated case, among the leading countries, by everlastingly rejecting...

We are interested in the occurrence of expectation-driven fluctuations of a rational bubble and the (de-)stabilizing role of monetary policy. Our explanation of fluctuations is based on credit market imperfections. For this purpose, we consider an overlapping generations exchange economy where...

We explore the existence of endogenous fluctuations with a rational bubble and the stabilizing role of fiscal and monetary policies. Consumers' credit constraints, the role of collateral and a portfolio choice are the key ingredients of our analysis. We consider an overlapping generations model...

The fiscal theory of the price level says that the price level can be made determinate if the government uses fiscal policies such that government liabilities explode unless the price in the first period is at the "right" level. The policy implications are disturbing, as they call for rather...

In this paper, we compare, first, the impact of a windfall and a boom sectors on the economy of an oil exporting country and their welfare implications ; in a second step, we analyze how monetary policy should be conducted to insulate the economy from the main impact of these shocks, namely the...

A robust prediction across a wide range of open-economy macroeconomic models is that an unanticipated increase in public spending in a given country appreciates it currency in real terms. This result, however, contradicts the findings of a number of recent empirical studies, which instead...
