This paper has two aims. First, to examine alternative ways of modeling VERS in imperfectly competitive markets. This is important, since the. effects of VERS are sensitive to the models used. Second, to argue that the effects of VERS also depend on whether goods are complements or Substitutes....

In May, 1981, a voluntary export restraint (VER) was placed on exports of automobiles from Japan to the United States. As trade policies go, this one was important. At about the same time, though to much less fanfare, international trade theorists were obtaining (then) startling results from...

In this paper, a structural gravity model is presented which features intra-sector heterogeneity in agricultural productivity systematically linked to land and climate characteristics. The “systematic heterogeneity” (SH) gravity model predicts that countries with similar land and climate...

In our European Economic Review (2002) paper, we used pre-1998 data on countries participating in and leaving currency unions to estimate the effect of currency unions on trade using (then-) conventional gravity models. In this paper, we use a variety of empirical gravity models to estimate the...

This paper studies two episodes where an exporting industry saw its sales plummet after importing countries banned their products to protect their citizens' health. The first case is the poisoned grapes crisis involving Chile and the United States in 1989. The second is the mad cows dispute...

After decades of successful growth, economic unions have recently become the focus of heightened political controversy. We argue that this is partly due to the growth of trade between countries that are increasingly dissimilar. We develop a theoretical framework to study the effects on trade,...

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...
