This paper studies arbitrage-free conditions for multiperiod asset pricing in frictional financial markets with proportional transaction costs. We consider the Euclidean space for weakly arbitrage-free security markets and Strongly arbitrage-free security markets, and establish the weakly...

Coase's seminal 1960 paper on externalities is associated with the so-called Coase Theorem which is stated in the literature in many forms. However, its main thrust was less to state a theorem than to challenge Pigou's earlier insistence on the need for government intervention through Pigouvian...

This paper focuses on the causes of increased wage inequality in OECD countries in recent years and its decomposition into the component factors of trade surges in low wage products and technological change that has preoccupied the trade and wages literature. It argues that the length of...

We explore the links between migration of labour and location specific (urban) pollution, suggesting a sense in which pollution can be welfare improving. In a conventional Harris-Todaro model of urban-rural migration, individuals migrate so as to equate the expected urban wage (given a downward...

We discuss most favoured nation (MFN) treatment in trade agreements, and its significance for developing countries, suggesting that its value to individual countries depends critically on the relevant model solution concept used to evaluate it. We analyze both rights to MFN treatment in foreign...

We compare the welfare costs of tax distortions of labour supply in one and two member household discrete and continuous labour supply (leisure consumption) choice models. In the discrete models taxes induce a large response from a subset of the population, while the majority of the population...

This paper uses computational techniques to assess whether or not various propositions that have been advanced as plausible in the literature on regional trade agreements may actually hold. The idea is to make probabilistic statements as to whether propositions of interest might hold, rather...

Most economists’ instinctive reaction to price controls is that they are harmful. If enforced, they result in shortages and resource misallocation. With weak enforcement they often result in black markets, and high transaction costs. In this paper we assess the pros and cons of rice price...

In this paper we use a general equilibrium model of Vietnam, calibrated to 1995 data, to analyze tax reform options for Vietnam. We focus on aggregate welfare impacts as well as welfare of household groups ranked by income. The main focus is on indirect tax reform (VAT), but we also examine...
