Cost-sharing policies for higher education have been implemented in several countries in various ways. We argue that to assess their appropriateness and facilitate their implementation it is necessary to develop statistical indicators of the distribution of returns. When starting a higher...

This paper analyzes the role played by inventories in the propagation of economic shocks using aggregate data for OECD countries and panel data from a sample of french firms. The approach is purely descriptive. The statement 'Production is more volatile than sales' appears to be sensitive to the...

We consider descriptive macroeconometric models with random coefficients in order to capture the possible relationship between the coefficients in the equations of the variables under the (partial) control of the authorities and those in the behavioral equations as observed in the rational...

This paper examines some theoretical results about the consequences of speculation on prices and welfare. On the one hand, we investigate the relationship between theorems of the theory of incomplete markets and the simplest speculation model. On the other hand, we present three simple examples...

We investigate the presence of self-fulfilling dynamics during the European sovereign crisis in the light of a theoretical model that we bring to the data. Our empirical framework allows us to empirically test the presence of self-fulfilling dynamics and to identify what may have driven the...
