Oil companies often announce revised estimates of their reserves. This indicates that stock uncertainty is a prevalent feature of natural resource industries. In this paper we consider the multi-deposit case where resource extraction produces information about the size of reserves. We show that...

In 1972, the potential gainfulness of free trade was established under fairly general assumptions — essentially those of Arrow and Debreu. Since then, the assumptions have been considerably weakened, notably by accommodating overlapping mortal generations and an infinite horizon. However,...

This paper presents a dynamic general equilibrium model of multi-country, two-good and two-factor, in which both long-run growth and international trade patterns are examined. In each country, government expenditure on a public intermediate good plays a crucial role in the realization of...

The existing theory of tied aid presupposes that trade and aid are conducted in terms of private consumption goods. However, in such a world aid can be effectively tied only if the recipient government somehow prevents its households from reselling the aid basket on world markets. That weakness...

We present a simple two(-country) by two(-good) differental game model of international trade in which the governments of the two countries play a tariff-setting game. We explicitly derive a unilateral optimum tarifff rate and then a Markov-perfect equilibrium pair of tariff strategies...
