The Kyoto Protocol, which came in force in February 2005, allows countries to resort to "supplementary activities" consisting particularly in carbon sequestration in agricultural soils. Existing papers studying the optimal carbon sequestration recognize the importance of the temporality of...

In this paper, we establish theorems of the alternative for a system described by inequalities, equalities and an inclusion, which are generalizations of Tucker's classical theorem of the alternative, and develop Kuhn-Tucker necessary conditions for efficiency to mathematical programs in normed...

The treatment of capital costs, as either fixed or variable is a key for estimating markups. Data leans clearly towards fixity, which explains the high markups emphasized in previous studies based on Roeger's methodology. Direct estimation from the ratio of output over variable costs is preferable.

In this paper, we propose an optimal algorithm for the Multiple-choice Multidimensional Knapsack Problem MMKP. The main principle of the approach is twofold : (i) to generate an initial solution, and (ii) at different levels of the tree search to determine a new upper bound used with a...

In this paper, we analyze the possible confusion in terms of long memory behavior of the autocorrelation function of a Markov switching model. Such a model is known to have a short memory behavior. Analyzing the value of sum of the transition probabilities and the number of switches inside such...

This paper investigates the choice of an intellectual protection regime for a process innovation. We set up a multi-stage model in which choosing between patent and trade secrecy is affected by three parameters : the patent strength defined as the probability that the right is upheld by the...

This paper provides a simple matching model in which unemployed workers and employers in large firms can be matched together through social networks or through more «formal» methods of search. We show that networks do not necessarily add new externalities and that some results previously...

Education constitutes one of the fundamental axes of the Cuban socialist development project and one of the means of achieving the goal of equality. In that country, the educational system has the purpose to call into question the capitalist division of labour, as well as the social division...

The efficiency defence was long delayed in the European merger control due to costly implementation issues. In this paper we argue that the upstream consequences of the efficiency defence should equally be considered, namely the improvement of the distribution of notified mergers through the...

We define a non-tâtonnement dynamics in continuous-time for pure-exchange economies with outside and inside fiat money. Traders are myopic, face a cash-in-advance constraint and play dominant strategies in a short-run monetary strategic market game involving the limit-price mechanism. The...
