Protection unconstrained by rules often varies substantially over time. Rules-based disciplines likeOECD industrial tariff bindings negotiated under GATT since 1947 and new Uruguay Roundbindings on agricultural and services trade and on developing country industrial tariffs, constrain...

We study the optimal trade policy against a foreign oligopoly withendogenous quality. We show that, under the Most Favoured Nation(MFN) clause, a uniform tariff policy is always welfare improvingover the free trade equilibrium. However, a nonuniform tariff policyis always desirable on welfare...

We explore the relationship between import protection and the household distribution of income. We first develop a general-equilibrium mapping from tariffs to household inequality measures. This also yields predictions for linkages between tariffs, development level, and observed household...

Anti-dumping actions are now the trade policy of choice of developing and transition economies. To understand why these economies have increasingly applied anti-dumping laws, we build a simple theoretical model of vertical intra-industry trade and investigate the strategic incentives of...

Most of the large tariff reductions achieved in multilateral tradenegotiations have involved tariff-cutting formulas such as the Swissformula. However, wide variations in initial tariff rates between activeparticipants call for new approaches under the Doha Development Agenda.This paper surveys...

Frequency of services and vehicle size are important policyinstruments of railway companies. Extending Mohring's basic'square root model' for frequencies, we arrive at more generalformulations for frequency, vehicle size and price underalternative regimes of welfare and profit optimisation. It...
