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...

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...

The paper sees countertrade - the tying of trade flows - as an insurance contract that mitigates contractual hazards and reduces the incentive for ex post `hold-up' when parties are `locked' in a relationship after they have made specific investment. This way tying is seen as a commitment device...

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...

The stalemate reached on launching negotiations on most of the Singapore Issues at Cancún provides an opportunity to revisit the knowledge base upon which proposals for international collective action may be drawn. This Paper examines the available evidence on public procurement practices in...

Because of concern that OECD tariff reductions will translate into worsening export performance for the least developed countries, trade preferences have proven a stumbling block to developing country support for multilateral liberalization. We examine the actual scope for preference erosion,...

International cooperation is generally driven by a desire to offset a negative spillover imposed by other countries or to help governments to overcome domestic political economy constraints that impede the adoption of welfare enhancing policy changes. In principle, both conditions are satisfied...
