This paper provides evidence based on French macroeconomic data, that shocks on the cost of oil inputs are transmitted asymmetrically to the prices of fuel. We use an error correction model to estimate the dynamics of the transmission of the cost of crude oil expressed in French currency, to the...

This paper studies the impact of financial inclusion on wealth accumulation. Exploiting the US interstate branching deregulation between 1994 and 2005, we find that an exogenous expansion of bank branches increases low-income household financial inclusion. We then show that financial inclusion...

This paper deals with the role of speculation on food prices' fluctuations in Senegal. The analysis is based on a nonlinear rational expectations commodity storage model which seems to be the appropriate approach to explain the behavior of the speculators who intervene on the food markets. The...

Using Consensus Forecasts monthly surveys, we show that experts' interest rate expectations in the Eurofranc market do not verify the rational expectations hypothesis. Instead, these expectations are found to be generated by a mixed process combining the traditional adaptive, regressive and...

Developing a model with a switching mechanism, we show how complex dynamics can be generated even though heterogeneity arises among agents with the same trading rules (fundamentalists). We assume that there are two experts which are imitated by other operators. We show that (i) market...

This paper presents the literature about econometric learning and its impact on the performances of monetary policy rules in the framework of the new canonical macroeconomic model. Rational expectations which are a building block of the original model can thus be replaced by expectations based...
