In this paper we first introduce an approach relying on market games to examine how successive oligopolies operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes...

In this paper, we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under the assumption and those resulting from the traditional example...

The aim of this paper is to develop a dynamic model of migra- tions, in which migration is driven by size asymmetries between coun- tries and by the relative preferences of consumers between private consumption and consumption of public goods. The dynamic trajec- tories heavily depend on the...

In this paper, we examine how uncertainty can affect successive mar- kets, when uncertainty can jointly influence both the upstream and down- stream markets conditions. The main result of the paper is that the equi- librium input and output quantities under stochastic dependence can be higher or...

We analyze the effects of labor migration flows on income taxation between two countries (regions) differing by the size of their population and the level of productive efficiencies. Residents, otherwise identical, are heterogeneous because they incur different migration costs. Each resident...

This paper examines how and why people migrate between two re- gions with asymmetric size. The agglomeration force comes from the scale economies in the provision of local public goods, whereas the disper- sion force comes from congestion in consumption of public goods. Public goods considered...

This paper investigates the optimal price sequence of a two period tentative to sell an indivisible good, with take-it-or-leave-it offers, in which the seller faces ambiguity about the buyers' willingness to pay. If the first round fails, the seller updates its beliefs on the state of the market...

In this paper, we extend the concept of stability to vertical collusive agreements, involving downstream and upstream firms, using a setup of successive Cournot oligopolies. We show that a stable vertical agreement always exists: the unanimous vertical agreement involving all downstream and...

We analyse the effects of migration on the production of public goods, income taxes, and on the welfare of residents in the sending and in the receiving country. Migration is based on income differences between countries. Different alternative scenarios are considered. In the first, we assume...
