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...

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

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...

This paper studies competition in regulation and commodity taxation between trading countries. We present a general equilibrium model in which destination based consumption taxes finance public goods, while regulation of entry determines the number of firms in the markets. We find (i) no...

The aim of this paper is to analyze within a simple model how a re- moval of bank secrecy can impact tax revenues and banks' profitability assuming that offshore centers are able to offer sophisticated but legal or not easily detectable tax planning. Two alternative regimes are considered. A...

In this paper, we analyze the long run economic performance of a small economy open to foreign investments. Policy instruments used to attract investments are taxes and attractive public infrastructures, whereas the policy choices of the rest of the world are taken as given. Applying the...

The aim of this paper is to analyse the impact of foreign investments on a small country's economy in a context of international competition. To that end, we model tax and infrastructure competition within a differential game framework between two unequal sized countries. The model accounts for...
