This paper surveys and critiques various methods of measuring nontariff trade measures (NTMs) for the purpose of determining which seem most promising for facilitating the process of reducing the trade-distorting effects of such policies through multilateral negotiations. Four measurement...

We use disaggregated data on trade flows, production, and trade barriers for 41 countries in 1988 to examine the political and economic determinants of non-tariff barriers, as well as the impact of protection (both tariff and non-tariff) on trade flows. We use an econometric framework that...

Structurally estimating the Grossman and Helpman (1994) model using coverage ratios that include non-tariff barriers leads to biased parameter estimates. We develop a quot;protection for salequot; theoretical framework consistent with the data, by explicitly allowing for non-tariff barriers....

This paper describes a new fact, then analyzes its causes and consequences: in most countries, import tariffs and non-tariff barriers are substantially lower on dirty than on clean industries, where an industry's “dirtiness” is defined as its carbon dioxide (CO2) emissions per dollar of...

Over the WTO years, the frequency of disputes and court rulings has trended downwards. Such trends are sometimes interpreted as symptoms of a dispute resolution system in decline. In this paper we propose a theory that can explain these trends as a result of judicial learning; thus according to...

We describe recent work on the theory of trade agreements that speaks to the purpose and design of GATT. Our discussion proceeds in three steps. First, we examine the purpose of a trade agreement. In both the traditional economic and the political-economy approaches to the study of trade...

We analyze whether preferential trade agreements (PTAs) affect the incidence and pattern of antidumping (AD) filings. We estimate AD provisions in PTAs have decreased the incidence of intra-PTA AD cases by 33-55% and have increased the number of AD actions against non-PTA members by 10-30%. The...

This paper discusses the role that trade can potentially play in both negotiating and operating a post Kyoto/post 2012 global climate policy regime. As an addition to the bargaining set for a global climate negotiation, trade in principle widens the range of jointly beneficial potential outcomes...

This paper assesses the impacts of the WTO Government Procurement Agreement (GPA) on trade in both goods and services among members using a gravity model applied to a panel dataset covering 20 OECD countries over the period 1996-2008 for trade in goods and 1999-2008 for trade in services. The...
