We build an infinite-horizon dynamic deterministic general equilibrium model with imperfect markets (because of borrowing constraints), in which heterogeneous agents invest in capital or/and financial asset, and consume. There is a representative firm who maximizes its profit. Firstly, the...

We consider a general equilibrium model with heterogeneous agents, borrowing constraints, and exogenous labor supply. First, the existence of intertemporal equilibrium is proved even if the aggregate capitals are not uniformly bounded above and the production functions are not time invariant....

We consider a small open economy with two productive sectors (an old and a new). There are two types of firms in the new industry: a well planted multinational firm and a potential domestic firm. Our framework highlights a number of results. First, in a poor country with low return of training...

This paper considers an infinite-horizon monetary economy with collateralized assets. A Central BanK lends money to households by creating short- and long-term loans. Households can deposit or borrow money on both short- and long-term maturity loans. If households want to sell a financial asset,...

This paper considers recycling in a general equilibrium model. It is shown that recycling should be subsidized if recycling costs are high, as an incentive to recycle all of the available waste. This tax incentive should vanish if recycling is profitable enough. In this case, recycling should...

This article proposes a non-parametric portfolio selection criterion for the static asset allocation problem in a robust higher-moment framework. Adopting the Shortage Function approach, we generalize the multi-objective optimization technique in a four-dimensional space using L-moments, and...

We give a structural description of the class C of graphs that do not contain a cycle with a unique chord as an induced subgraph. Our main theorem states that any connected graph in C is a either in some simple basic class or has a decomposition. Basic classes are cliques, bipartite graphs with...

Recently, much research interest is directed towards the impact of migration on the sending country. However, we think that this literature does not successfully analyse the effects of migration on unemployment and wage rates especially in urban areas. It studies the effect of one king of...

This paper offers an analysis of the career security according to three criteria defined by the CERC (2005) : the job stability (length of job tenure), the job security (short duration of unemployment after an external mobility) and the income security (maintaining or increasing incomes). We try...
