We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003). A nonlinear structural estimation procedure identifies a set of core parameters and unobserved...

Many contemporary theoretic studies of trade over geography reduce to an ex- amination of constant-elasticity reactions to changes in iceberg trade costs. These impacts are readily analyzed in simple constant-returns models based on the Arm- ington (1969) assumption of regionally differentiated...

The demand for accountability in "Aid-for-Trade" (AFT) is increasing but monitoring has focused on case-studies and impressionistic narratives. The paper reviews recent evidence from a wide range of studies, recognizing that a multiplicity of approaches is needed to learn what works and what...

This paper evaluates the effects of the FAMEX export promotion program in Tunisia on the performance of beneficiary firms. While most studies assess only the short-term impact of such programs, we consider also the longer-term impact. Estimates suggest that beneficiaries initially saw both...

The liberalization of the basic telecommunications sector in Asian countries is examined in this paper with a view to identify the elements of good policy and examine how it can be promoted through multilateral negotiations. We find that despite the move away from traditional public monopolies,...

This paper examines liberalization of the basic telecommunications sector in a number of Asian countries and the role of the General Agreement on Trade in Services (GATS) in this process. It begins by explaining the working of the GATS as a mechanism for multilateral liberalization efforts. It...

A major challenge for the multilateral trading system is to secure the benefits of trade liberalization without infringing on the freedom of governments to pursue legitimate domestic objectives. The difficulty lies in distinguishing between two types of situations. In one, a non-protectionist...

This paper is concerned with three problems in the interpretation of the national treatment obligation in GATS. First, the precise domain of Article XVII on national treatment has not been clearly delineated, particularly in relation to Article XVI dealing with market access. Secondly, there is...

This paper shows that environmental, labour and other standards can be effective strategic policy instruments even when they are strictly non-discriminatory. This is because standards can be set which the low cost producer optimally chooses not to meet, allowing the high cost producer to...

The objective of this paper is to assess the adequacy of multilateral rules dealing with monopolies and state enterprises, particularly in the domain of services. This paper argues that since these rules depend largely on the other obligations undertaken by Members, a variety of exemptions and...
