Thanks to its empirical success, the gravity approach is widely used to explain trade patterns between countries. In this article we question the simple application of this approach to product/sector-level trade on two grounds. First, we demonstrate that the traditional Armington version of...

While methodologies and survey techniques recorded progress over the years, corruption measurement remains a many-headed monster. Since 2003 and the first publication of Transparency International's Global Corruption Barometer, researchers have access to population's feeling about the corruption...

In this paper we evaluate the respective effects of demographic change, changes in morbidity and changes in practices on growth in health care expenditures. We use microdata, i.e. representative samples of 3441 and 5003 French individuals observed in 1992 and 2000. Our data provide detailed...

The recognition that contracts have a time dimension has given rise to a very abundant literature since the end of the 1980s. In such a dynamic context, the contract may take place over several periods and develop repeated interactions. Then, the principal topics of the analysis are commitment,...

The Objective of this paper is to test the consequences of changes in health status of future cohorts of French elderly on healthcare expenditures. We value the precise effect of epidemiological and life expectancy changes on health expenditures for 2025 by using a markovian microsimulation...

Whatever the econometric model which we study; any simulation requires a perfectly definite DGP. Thus, even if all software can generate standard normal distributions, we need methods not programmed to control higher moments. For all these methods, we need to estimate the parameters connected to...

Since the creation of the European Union Emissions Trading Scheme (EU ETS) in 2005, a burgeoning academic literature has emerged to identify the factors that shape the price of carbon, where one European Union Allowance is equal to one ton of CO2-equivalent emitted in the atmosphere. Thus, there...

We examine the consequences on impairment testing disclosures of auditor-pair choice made by French listed companies where two (joint) auditors are required by law. Managers are likely to manipulate impairment-testing disclosures since it relies on unverifiable fair value estimates (e.g.,...

The impact of wholesale prices is examined in a context where the end customer access both free content and payper-use content, delivered by two different providers through a common network provider. We formulate and solve the game between the network provider and the pay-per-use content...

n this paper we study the problem of long-term capacity adequacy in electricity markets. We implement a dynamic model in which firms compete for investment and electricity production under imperfect Cournot competition. The main aim of this work is to compare three investment incentive...
