In France, having more than two children has a causal negative impact on mothers' labour supply. The question addressed in this paper is whether some family policies alter this effect. The idea is that by improving the conditions of the conciliation between family life and professional life,...

This article concerns the governance of the World Bank (WB) and tries to determine if it grants the decision-making power to Most Developed Countries (MDC) of the OECD. First of all, we demonstrate that these countries have effectively the decision-making power within three authorities of...

In this paper we deal with the problem of non-stationarity encountered in a lot of data sets, mainly in financial and economics domains, coming from the presence of multiple seasonnalities, jumps, volatility, distorsion, aggregation, etc. Existence of non-stationarity involves spurious behaviors...

This paper develops a method for pricing bivariate contingent claims under General Autoregressive Conditionally Heteroskedastic (GARCH) process. As the association between the underlying assets may vary over time, the dynamic copula with time-varying parameter offers a better alternative to any...

This article analyses through a rent seeking model, the relationship between institutions' quality and natural resources. Depending on the institutions quality, each country has a specific structural capacity to stand natural resources dependency. It is shown that for each country, a threshold...

Despite its increasing role in the economic theory, the externality concept seems to evade any attempt for a rigorous and consensual definition, and this from Meade's original article to Arrow's work. An externality is soon seen as an unpriced "direct interaction" but some of its a priori...

This article investigates the co-evolution of labor relationships and workers preferences. According to recent experimental economics findinggs on social preferences, the workforce is assumed to be heterogeneous. It is composed by both cooperative and non-cooperative workers. In addition, firms...

We introduce cooperative TU-games on concept lattices, where a concept is a pair (S,S') with S being a subset of players or objects, and S' a subset of attributes. Any such game induces a game on the set of players/objects, which appears to be a TU-game whose collection of feasible coalitions is...

This article uses household data to measure the substitutability between time and money for eight commodity groups and different countries. The elasticities estimated using the household's market wage and an estimated opportunity cost of time are positive, indicating substitutability, and much...

We propose a simple model of a mating economy in both monogamous and polygynous cultures, and derive implications for how polygyny affects individual and aggregate fertility. We find that an attractive woman is more likely to find a high-status husband. However, when polygyny is allowed,...
