We investigate in this paper the theory and econometrics of optimal matchings with competing criteria. The surplus from a marriage match, for instance, may depend both on the incomes and on the educations of the partners, as well as on characteristics that the analyst does not observe. The...

An indivisible good is to be consumed by one of several agents. The consumption involves identity-dependent externalities to the non-consumers. Resale markets for such goods are analysed in various institutional settings with complete information, assuming the agents cannot commit to future...

We study in the laboratory, a variant of the house allocation with existing tenants problem where agents are partitioned into tiers with different privileges. Members of higher tiers receive their allocation before those in lower tiers and can also take the endowment of a member of a lower tier...

Efficient measures are often not implemented because of their potentially damaging effects on distribution, yet these distributional effects are scarcely studied in economics because of the idea that they are case specific. In this paper we show that when we can separate the effect on efficiency...

School choice aims to improve (1) the matching between children and schools and (2) students’ educational outcomes. Yet, the concern is that disadvantaged families are less able to exercise choice, which raises (3) equity concerns. The Boston mechanism (BM) is a procedure that is widely used...

This Paper shows that identical offers in an ultimatum game generate systematically different rejection rates depending on the other offers that are available to the proposer. This result casts doubt on the consequentialist practice in economics of defining the utility of an action solely in...

We analyse the interaction of asymmetric industries in international vertically related markets. Each downstream firm bargains efficiently with its domestic supplier in a first stage and with the foreign supplier in a second stage. The asymmetry in upstream costs leads to inter-industry trade....

This Paper discusses a number of issues in the context of the debate on intellectual property in less developed countries (LDCs). It starts by discussing the consequences of IP enforcement in LDCs for global innovation and welfare in poorer countries. It then considers the costs and benefits of...

The theory of comparative advantage is at the core of neoclassical trade theory. Yet we know little about its implications for how nations should conduct their trade policy. For example, should import sectors with weaker comparative advantage be protected more? Conversely, should export sectors...

This Paper develops a model for analysing the costs and benefits of intellectual property enforcement in LDCs. The North is more productive than the South and is the only source of innovator. There are two types of goods, and each bloc has a comparative advantage in producing a specific type of...
