We prove the existence of subsidy free and sustainable pricing schedule in multiproduct contestable markets. We allow firms to discriminate the local markets that are composed by a set of the products line and a set of agents. Results are obtained under an assumption of fair sharing cost and...

A pure hedonic game describes the situation where player's utility depends only on the identity of the members of the group he belongs to. The paper provides a necessary and sufficient condition for the existence of core-partition in hedonic games. The condition is based on a new concept of...

By Covered Interest rate Parity (CIP), the FX swap implied currency interest rates should coincide with actual interest rates. When a difference occurs, the residual is referred to as the cross currency basis. We link the Euro-Dollar currency basis (e.g. in 2008) to shadow prices of dollar...

We build a benchmark framework to study optimal land use, encompassing land use activities and environmental degradation. We focus on the spatial externalities of land use as drivers of spatial patterns : even if land is immobile by nature, location's actions affect the whole space through...

Thirty years after its implementation by the World Bank (WB) in Sub-Saharan Africa (SSA), the empirical evidences point out the very mixed results privatization has produced, particularly in the infrastructures sector. Despite of this, the WB has intensified its support to infrastructures...

This paper addresses the economic impact of the European Union Emission Trading Scheme (EU ETS) for carbon on wholesale electricity prices in France and Germany during the Kyoto commitment period (2008-2012). Specifically, we use first identify a structural break occurred on the carbon spot...

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...

In this paper, we present a non-cooperative wage bargaining model in which preferences of both parties, a union and a firm, are expressed by sequences of discount factors varying in time. We determine subgame perfect equilibria for three cases when the strike decision of the union is exogenous :...

Securities markets theory includes repo and distinguishes shorting from issuing. Here we revisit whether trading alone can give rise to Ponzi schemes and rational bubbles. We show that under the same institutional arrangements that limit re-hypothecation (e.g., through segregated haircut rules...

This paper shows that it is possible to extend the scope of the existence of rational bubbles when uncertainty is introduced associated with rank-dependent expected utility. This RDU assumption can be viewed as a transformation of probabilities depending on the pessimism/optimism of the agent....
