This paper proposes that Viner's celebrated trade diversion and trade creation terminology for the customs union problem be abandoned. As the alternative is offered a welfare calculus based upon the terms-of-trade and volume-of-trade taxonomy from the theory of tariffs. The paper discusses, by...

This paper compares two possible formats for free trade in the Americas: a system of spokes surrounding a U.S. hub, and a free trade area. The paper identifies the sources of welfare change, and it argues that a country's attitude towards a system depends on whether the arrangement is a...

We study the implications of customs union formation for multilateral tariff cooperation. We model cooperation in multilateral trade policy as self-enforcing, in that it involves balancing the current gains from deviating unilaterally from an agreed-upon trade policy against the future losses...

This paper uses computational techniques to assess whether or not various propositions that have been advanced as plausible in the literature on Customs Unions (or other regional trade agreements) may actually hold. The idea is to make probabilistic statements as to whether propositions of...

This paper looks empirically into the behavior of multinational firms in international oligopolistic markets with trade balance constraints. I show how a particular form of non-tariff barrier applied at the firm level can lead to an increase in trade flows in the presence of intra-firm strategic...

Until NAFTA, analyses of preferential trading arrangements began by assuming a customs union with a common external tariff, and the differences between customs unions and free trade agreements (FTAs) have been little analyzed. This paper points to some of the differences between FTAs and customs...

At a time of historic challenges to the viability of the Eurozone, we assess the contribution of the EU and the Euro to equity market integration in Europe. We use a simple and essentially model free measure of bilateral market segmentation: two countries are segmented if there is a wide...

The empirical objective of this study is to account for the time-variation the covariances between markets. Using data on sixteen national stock markets, we estimate a multivariate factor model in which the volatility of returns is induced by changing volatility in the orthogonal factors. Excess...

How important is foreign diversification? In this paper, we re-examine this question motivated by findings from the literature about foreign companies that are listed on US exchanges. Specifically, domestic portfolios including cross-listed stocks can provide the same diversification as foreign...

Can financial integration, particularly the cross-border investments of multinational firms, help explain the synchronization of business cycles? This paper presents evidence on the comovement of returns and investment within U.S. multinational firms to address this question. These firms...
