For two independent principles of intergenerational equity, the implied discount rate equals the growth rate of real per-capita income, say 2%, thus falling right into the range suggested by the U.S. Offce of Management and Budget. To prove this, we develop a simple tool to evaluate small policy...

In this paper we investigate the welfare effects of capital income taxation in a standard one commodity general equilibrium model with incomplete markets (GEI) and production. We consider a competitive economy of two periods with uncertainty over a finite number S of possible states of nature...

Current Office of Management and Budget (OMB) guidelines use the interest rate as a basis for the discount rate, and have nothing to say about an intergenerationally fair discount rate. We derive this discount rate by differentiating a social welfare function with respect to perturbations in...

In this paper we investigate the welfare effect of capital income taxation in a standard one commodity general equilibrium model with incomplete markets (GEI) and production. We consider a competitive economy of two periods with uncertainty over a finite number S of possible states of nature...

In an exogenous-growth economy with overlapping generations (OG) we analyse local stability of the balanced growth equilibria with respect to perturbations of consumption endowments, thought of as the "monetised" value of a government policy to individuals. We show that perturbed economies have...

The popular discounted utilitarian criterion for infinite horizon social choice has been criticized on the ground that it treats successive generations unfairly. I propose to evaluate intergenerational welfare with a rank- discounted utilitarian (RDU) criterion instead. The criterion amounts to...

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a...

This paper attempts to give a rationale to public announcements, so often observed in the real world, and to formalize the idea that they can be used as a form of equilibrium selection device when multiple equilibria arise. It also shows how announcements solve the problems of coordination...

In this paper, we study a pure exchange economy with idiosyncratic uncertainty, hidden action and multiple consumption goods.We consider two different market structures: contingent markets on the one hand, and financial and spot markets on the otherhand. We propose a competitive equilibrium...

There exist congenital diseases that reduce newborns' potential opportunities. This reduction is sometimes alleviated if the congenital disease is early detected thanks to a newborn screening program. We propose an outcome measurement of newborn screening programs based on the opportunity gains...
