We use King's methodology to describe the welfare effects of six VAT reform proposals for France, among which the proposal of the European Commission. Nous utilisons la méthodologie de King pour décrire en termes de variation de bien-être les effets de six propositions de réforme de la TVA...

Dieser Aufsatz beschreibt neuere Entwicklungen in der Aggregationstheorie sowie ausgewählte empirische Arbeiten. Diese stellen exemplarisch dar, wie die Mikroökonometrie eingesetzt werden kann, um Aggregationsprobleme zu untersuchen und approximative Lösungen zu finden. Der Schwerpunkt liegt...

This paper studies the aggregate substitution and expansion effects triggered by changes in input prices, in a context where firms supply a homogenous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this...

The availability of quantity information along with expenditure information in some household surveys allows the estimation of price reactions on the basis of unit values. We compare two specifications that have been proposed in this context by Deaton (1990) and Crawford et al. (1997) in order...

Motivated by Manski and Tamer (2002) and especially their partial identification analysis of the regression model where one covariate is only interval-measured, we present two extensions. Manski and Tamer (2002) propose two estimation approaches in this context, focussing on general results. The...

Motivated by Manski and Tamer (2002) and especially their partial identification analysis of the regression model where one covariate is only interval-measured, we offer several contributions. Manski and Tamer (2002) propose two estimation approaches in this context, focussing on general...

We use a multivariate hazard model for the analysis of data on the timing of ratifications of different conventions. The model accounts for two random effects, one at the country level and the other at the convention level. We use a semi-parametric Bayesian approach, based on the partial...
