In this paper, we give a characterization of meet-projections in simple atomistic lattices that generalizes results on the aggregation of partitions in cluster analysis.

We consider a stochastic financial exchange economy with a finite date-event tree representing time and uncertainty and a nominal financial structure with possibly long-term assets. We exhibit a sufficient condition under which the payoff matrix and the full payoff matrix have the same rank....

In this paper, we try to understand the economic policies choice of countries in terms of size. According to the case whether a country is large or small, it will have different incentives in the choice of its growth strategy. Theoretically, a large country would prefer use a policy which...

In this paper, we focus on the concept of size of country (or economy). Specifically, within the European Union (EU), we look for growth discrepancies between countries according to their size. We try to explain growth differential using arguments related to the size of countries. Thus, we...

This paper deals with performance measurement of financial structured products. For this purpose, we introduce the SharpeOmega ratio, based on put as downside risk measure. This allows to take account of the asymmetry of the return probability distribution. We provide general results about the...

This paper examines the influence of political ideology on economic growth in the French democracy since 1871. It does so by addressing three main issues : the property and the reliability of a political ideology index in the long-run, the robustness of the relationship between ideology and...

The forecasting literature has identified three important and broad issues: the predictive content is unstable over time, in-sample and out-of-sample discordant results and the problematic statistical inference with highly persistent predictors. In this paper, we simultaneously address these...

In this paper, nine memory parameter estimation procedures for the fractionally integrated I(d) process, semi-parametric and parametric, which prevail in the existing literature are reviewed ; through the simulation study under the ARFIMA (p,d,q) setting we cast a light on the finite sample...

We build a model to study optimal land use, encompassing land use activities, pollution and climate change. This benchmark set-up allows us to identify the spatial drivers behind the interaction between land use and the environment. Pollution generates local and global damages since it flows...

An element of the possibly unbounded core of a cooperative game with precedence constraints belongs to its bounded core if any transfer to a player from any of her subordinates results in payoffs outside the core. The bounded core is the union of all bounded faces of the core, it is nonempty if...
