In overlapping generations models with endogenous fertility wherein the retired partake of consumption but do not contribute to production (through their labor), fertility has a positive and a negative externality. These can be internalized through a child allowance (or tax) or a linkage between...

This paper discusses the efficiency of a pay-as-you-go pension reform by introducing a child benefit in an endogenous fertility setting. In the model of a small open economy, higher fertility is associated with a reduction of lifetime labor supply. The optimum share of fertility-related pensions...

Payments for ecosystem service outputs have become a popular policy prescription for a range of agri-environmental schemes. The focus of this paper is on the choice of sets of instruments in an ecosystem service principal-agent model that addresses adverse selection and moral-hazard. Results...

We consider a general economy, where agents have private information about their types. Types can be multi-dimensional and potentially interdependent. We show that, if the realized frequency of types (the exact number of agents for each type) is common knowledge, then a mechanism exists, which...

We study how securities and trading mechanisms can be designed to optimally mitigate the adverse impact of market imperfections on liquidity. Asset owners seek to obtain liquidity by selling their claims on future cash-flows, on which they have private information. Our analysis encompasses both...

We study second-degree price discrimination in markets where the product traded by the monopolist is access to other agents. We derive necessary and sufficient conditions for the welfareand the profit-maximizing mechanisms to employ a single network or a menu of non-exclusive networks. We...

We study mechanisms for selecting up to m out of n projects. Project managers’ private information on quality is elicited through transfers. Under limited liability, the optimal mechanism selects projects that maximize some function of the project’s observable and reported characteristics....
