This paper examines the emergence and dynamics of border effects over time. We exploit the unique historical setting of the multinational Habsburg Empire prior to the Great War to explore the hypothesis that border effects emerged as a result of persistent trade effects of ethno-linguistic...

The Zollverein was arguably the most important free-trade agreement of the 19th century. This paper investigates the economic impact of the Zollverein on trade in Germany. Although 1834 is the official date of the Zollverein's establishment, member states in fact joined in a non-random sequence...

This article analyzes the stability of bimetallism for countries operating in integrated bullion markets who enact different legal ratios. I articulate a new theoretical framework to demonstrate that two countries can both be bimetallic only if they coordinate their legal ratios. The theoretical...

This paper asks whether Germany was ever an economically integrated area. I explore the geography of trade costs in a new data set of about 40,000 observations on regional trade flows within and across the borders of Germany over the period 1885 – 1933. There are three key results. First, the...

A large literature documents the impact of borders on trade. However, in all these studies border effects are identified from cross-sectional variation alone. We do not know the "treatment effect" of borders nor can we rule out reverse causation. Here, we exploit the border changes imposed...

Regional integration is on the rise again, despite its apparent failure among developing countries in the past. The paper first surveys the ambiguous economics of customs unions. We emphasize that the traditional dichotomy between `trade creation' and `trade diversion' is not particularly...

Using an extension of the influence-driven lobbying approach developed by Grossman and Helpman, we study the impact of regional integration arrangements (RIAs) on trade policy towards non-members in a three-good, three-country model. We explore under what conditions the formation of an RIA...

This paper studies the effect of switching from the destination to the origin principle of taxation on non-cooperative commodity tax equilibrium. When taxes are constrained to uniformity across commodities, the switch has no effect. When differentiated taxes are allowed, the effects of the...

This paper shows that the WTO's Article XXIV increases the likelihood of free trade, but may worsen world welfare when free trade is not reached and customs unions (CUs) form. We consider a model of many countries. Article XXIV prevents a CU from raising its common external tariff, which makes...

How are the benefits - and costs - of a customs union divided between member countries? Outcomes depend on the comparative advantage of member countries, relative to each other and to the rest of the world. Countries with a comparative advantage between that of their partners and the rest of the...
