Is a public regulation of food price volatility feasible in Africa? An arch approach in Kenya
D'Hôtel, Elodie Maître; Cotty, Tristan Le; Jayne, Thomas - HAL - 2012
tradition of public intervention, and by the persistence of highly volatile prices. The consistency of the policy use appears to … be key factor influencing the degree of price volatility. Applied to trade policies, this consistency is defined by the … temporal relationship between the tariff level and the international price changes. To test the influence of policy consistency …

A Stability Index for Local Effectivity Functions
Abdou, Joseph - HAL - 2010
We study the structure of unstable local effectivity functions defined for n players and p alternatives. A stability index based on the notion of cycle is introduced. In the particular case of simple games, the stability index is closely related to the Nakamura Number. In general it may be any...

Stability Index of Interaction forms
Abdou, Joseph - HAL - 2008
An interaction form is an abstract model of interaction based on a description of power distribution among agents over alternatives. A solution known as the settlement set is defined at any preference profile. Necessary and sufficient conditions for stability, that is the existence of...

On the optimal control of a linear neutral differential equation arising in economics
Boucekkine, Raouf; Fabbri, Giorgio; Pintus, Patrick-Antoine - HAL - 2011
In this paper, we apply two optimization methods to solve an optimal control problem of a linear neutral differential equation (NDE) arising in economics. The first one is a variational method, the second follows a dynamic programming approach. Due to the infinite dimensionality of the NDE, the...

Markov switching quadratic term structure models
Goutte, Stéphane - HAL - 2013
In this paper, we consider a discrete time economy where we assume that the short term interest rate follows a quadratic term structure of a regime switching asset process. The possible non-linear structure and the fact that the interest rate can have different economic or financial trends...

Values for Markovian coalition processes
Faigle, Ulrich; Grabisch, Michel - HAL - 2012
Time series of coalitions (so-called scenarios) are studied that describe processes of coalition formation where several players may enter or leave the current coalition at any point in (discrete) time and convergence to the grand coalition is not necessarily prescribed. Transitions from one...
