This paper empirically explores the political-economic determinants of why governments choose to tax or subsidize trade in agriculture. We use a new data set on nominal rates of assistance (NRA) across a number of commodities spanning the last four decades for 64 countries. NRAs measure the...

We construct a three-country, two-bloc, multi-product trade model in which tariff agreements between customs union members are binding whereas inter-bloc tariff agreements are self-enforcing. Our main objective is to explore how the liberalization of trade between customs union members (i.e. the...

This paper argues that further moves to liberalize trade and to implement existing GATT disciplines may have a greater impact on global competition than the pursuit of harmonized multilateral competition policy disciplines. It also suggests that current GATT rules and case law provide scope for...

Many commentators purport to use the Kemp-Wan Theorem to discuss the effects of regional integration schemes on non-member countries, and to operationalize the theorem in terms of the share of member countries' imports from non-members. This paper shows that Kemp and Wan (1976) say nothing about...

In this paper we use detailed trade and production data and a theoretically consistent model of demand - the Almost Ideal Demand System - to estimate bilateral trade elasticities, the key parameters required for quantification of the effects of the `1992' programme. Initial results for 70 West...

We consider a simple three-country, multi-commodity trade model in which two custom union members that have successfully coordinated their external tariff policies are in the process of deepening the integration of their internal markets through the removal of tariffs on intra-union trade. Union...

This paper surveys the major options that have been proposed concerning a possible agreement on trade-related anti-trust principles and evaluates both their desirability and feasibility. Three criteria are used to evaluate the options: (i) the extent to which they enhance the contestability of...

This paper discusses what could be done to expand services trade and investment through a multilateral agreement in the WTO. A distinction is made between market access liberalization and the regulatory preconditions for benefiting from market opening. We argue that moving forward on...

WTO members are starting to consider whether and how to develop multilateral disciplines on competition policies. These discussions are taking place in the absence of concerted efforts to compile comparable information on the conditions of competition existing on member country markets. We argue...

Actual and potential competition is a powerful source of discipline on the pricing behavior of firms with market power. A simple model is developed that shows that the effects of import competition and domestic entry regulation on industry price-cost markups depend on country size. Barriers to...
