The paper is devoted to an econometric analysis of learning foreign languages in all parts of the world. Our sample covers 193 countries and 13 important languages. Four factors significantly explain learning. All four affect the broad decision to learn but the last two also point to the choice...

The paper is not intended for game theorists - unless they are interested in learning how their theories, and the theory of environmental games as developed in a forthcoming book, are being used for studying the current problem of climate change. Similarly for economists. In general, the...

In this paper, we analyse tax harmonisation in the framework of two countries asymmetric in their capital-labour endowment. In the first part, countries play a non-cooperative game and we examine how na- tional fiscal policies are decided according to majority voting. At the Nash equilibrium,...

This paper is a study of money in overlapping generations models with cash-in-advance constraints. We first offer a brief review of different features of the cash-in-advance constraint. Then we propose a general formulation and study the neutrality of money. We show that both neutrality and...

Tradable permits are now widely used to control pollution. We investigate the implications of setting up such a system in another area population control, either domestically or at the global level. We first generalize the framework withboth tradable procreation allowances and tradable...

First, we briefly discuss the very idea of tradable quotas, looking at a set of cases in which it has been proposed (but not implemented) outside the realm of pollution control and natural resources management. Next we study a proposal of tradable procreation quotas. We generalize Boulding’s...

This paper deals with the effect of conjectures in a strategic setting.To do this it focuses on the so-called Conjectural Variation Equilibrium (CVE).According to this concept, each agent chooses his most favorable action taking into account that rival strategies are a conjectured function of...

This paper contributes to the literature on budget deficits and inflation in high inflation economies. The main finding is that recurrent outbursts of extreme inflation in these economies can be explained by a certain hysteresis effect associated with public finance. This interpretation meets...

The Atkinson-Stiglitz Theorem shows that with weakly separable preferences, differential commod- ity taxes are not needed if an optimal nonlinear income tax is imposed. Redistributive objectives can be achieved with the income tax alone even if goods differ considerably in their income...
