Numerical simulation exercises to analyze the impacts of potential changes in non-tariff policies commonly use ad valorem equivalent tariff treatment even though estimated impacts using explicit model representation and ad valorem equivalent treatments will differ. The difficulty for modellers...

This paper looks at a model in which two countries trade agricultural and manufactured commodities. The manufactured-goods sector produces with increasing returns to scale under conditions of monopolistic competition. It is shown that an increase in land endowment (or an increase in agricultural...

A system of tradable permits in the standard setting is effective in attaining the policy objective with regard to pollution reduction at the least cost. This outcome is challenged in case of a tradable permit system in a federal state with individual states having discretionary power regarding...

This paper revisits the debate about the appropriate differential equation that governs the evolution of knowledge in models of endogenous growth. We argue that the assessment of the appropriateness of an equation of motion should not only be based on its implications for the future, but that it...

This paper considers the allocation of two types of individuals differentiated by levels of talent within and between two countries when they choose to be workers or entrepreneurs. The equilibrium with international migrations requires both countries to be sufficiently different in talent...

The enlargement of the European Monetary Union is likely to lead to an increase in uncertainty regarding the transmission of monetary policy for the larger union. Adding new members to the central bank council will in addition imply that the policy reaction of the enlarged council will be...

In several European merger cases competition authorities have demanded that the merging firm auctions off virtual capacity. The buyer of virtual capacity receives an option on an amount of output at a pre-specified price, typically equal to marginal cost. This output is sold in the market in...

In many auctions, the auctioneer is an agent of the seller. This invites corruption. We propose a model of corruption in which the auctioneer orchestrates bid rigging by inviting a bidder to either lower or raise his bid, whichever is more profitable. We characterize equilibrium bidding in...

Empirical evidence from the U.S. and the European Union suggests that regions which contribute to interregional redistribution face weaker borrowing constraints than regions which benefit from interregional redistribution. This paper presents an argument in favor of such differentiated budgetary...

This paper analyzes the sustainability of intergenerational transfers in politico-economic equilibrium. Embedding electoral competition for the votes of old and young households in the standard Diamond (1965) OLG model, we find that intergenerational transfers naturally arise in a Markov perfect...
