Using millions of individual gasoline prices collected at a daily frequency, we examine the speed at which market refined oil prices are transmitted to consumer liquid fuel prices. We find that on average gasoline prices are modified once a week and the distribution of price changes displays a...

We propose to study the dynamic impact of adjustment costs in capital on the two sectors model with positive sector specific externalities. We proove that such costs are able to lead to endogenous fluctuations by financial transmission mechanism. Indeed, since adjustments costs are linked to the...

Do adjustment costs able to modify the dynamic of the two sectors model? We examine the impact of adjustment costs in capital on the properties of long-run equilibrium. We propose to analyse how the positive and negative degrees of adjustment costs could interplay with the local indeterminacy...

This paper suggests a modelling of the labelling procedure consistent with empirical observations, that allows the endogenous calculation of labelling criteria. The authority in charge of the labelling program chooses the level of labelling criteria so as to maximise the social surplus,...

This paper analyses price competition in the case of two firms operating under constant returns to scale with more than one production factor. Factors are chosen sequentially in a two-stage game generating a soft capacity constraint and implying a convex short term cost function in the second...

Under what conditions should a central bank adopt an inflation targeting regime ? This is the main question we address in this paper. A large part of the literature puts forward that these regimes should have to be adopted, as they yield higher macroeconomic performances. We analyze the issue of...

Using micro price data, we document new facts on price rigidity in France: (i) each month 20.1% of prices are changed, which compares with 24.1% in the United States. Excluding sales, however, the fraction of prices modified each month is about the same in France and in the United States (around...

This paper presents evidence from three French VAT reforms showing that tax shifting on prices operates differently upwards and downwards. This may appear as a paradox when reading usual studies on price shifting. This paper puts forward two different asymmetric effects. The first one is linked...

The point of this paper is to measure empirically the distribution of the commodity tax burden between consumers and producers. For that purpose, two French reforms are studied. These reforms are steep decreases of the VAT rate on housing repair services on the one hand, and on new car sales on...
