A Theory of Economic Unions: A Comment
Gino Gancia, Giacomo Ponzetto and Jaume Ventura have written an extremely interesting paper on a topic that is very timely for the global economy. In this article, I will first argue that GPV have succeeded in formalizing their hypothesis, and that while providing very suggestive analytical results, additional work can and should be done with the model, especially with regards to relative changes in the relative weights of incumbent countries. Second, I will comment on the potential insights if the rest of the world is modeled more realistically. Third, I will call for extending the baseline ...

Estimating Border Effects: The Impact of Spatial Aggregation
Trade data are typically reported at the level of regions or countries and are therefore aggregates across space. In this paper, we investigate the sensitivity of standard gravity estimation to spatial aggregation. We build a model in which symmetric micro regions are aggregated into macro regions. We then apply the model to the large literature on border effects in domestic and international trade. Our theory shows that aggregation leads to border effect heterogeneity. Larger regions or countries are systematically associated with smaller border effects. The reason is that due to spatial ...
“Conditional PPP” and Real Exchange Rate Convergence in the Euro Area
While economic theory highlights the usefulness of flexible exchange rates in promoting adjustment in international relative prices, flexible exchange rates also can be a source of destabilizing shocks. We find that when countries joining the euro currency union abandoned their national exchange rates, the adjustment of real exchange rates toward their long-run equilibrium surprisingly became faster. To investigate, we distinguish between differing rates of purchasing power parity (PPP) convergence conditional on alternative shocks, which we refer to as ?conditional PPP.? We find that the ...
Currency Unions and Regional Trade Agreements: EMU and EU Effects on Trade
The effects of the European Economic and Monetary Union (EMU) and European Union (EU) on trade are separately estimated using an empirical gravity model. Employing a panel approach with both time-varying country and dyadic fixed effects on a large span of data (across both countries and time), it is found that EMU and EU each significantly boosted exports. EMU expanded European trade by 40% for the original members, while the EU increased trade by almost 70%. Newer members have experienced even higher trade as a result of joining the EU, but more time is necessary to see the effects of their ...
Currency unions and trade: a post-EMU mea culpa
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 currency union effect on trade and exports, using recent data which includes the European Economic and Monetary Union (EMU). We have three findings. First, our assumption of symmetry between the effects of entering and leaving a currency union seems reasonable in the data but is uninteresting. Second, ...
Disentangling the Effects of the 2018-2019 Tariffs on a Globally Connected U.S. Manufacturing Sector
Since the beginning of 2018, the United States has undertaken unprecedented tariff increases, with one goal of these actions being to boost the manufacturing sector. In this paper, we estimate the effect of the tariffs---including retaliatory tariffs by U.S. trading partners---on manufacturing employment, output, and producer prices. A key feature of our analysis is accounting for the multiple ways that tariffs might affect the manufacturing sector, including providing protection for domestic industries, raising costs for imported inputs, and harming competitiveness in overseas markets due ...
The Local Impact of Containerization
We investigate how containerization impacts local economic activity. Containerization is premised on a simple insight: packaging goods for waterborne trade into a standardized container makes them dramatically cheaper to move. We use a novel cost-shifter instrument -- port depth pre-containerization -- to contend with the non-random adoption of containerization by ports. Container ships sit much deeper in the water than their predecessors, making initially deep ports cheaper to containerize. Consistent with New Economic Geography models, we find that counties near container ports grow an ...
Investment Responses to Trade Liberalization : Evidence from U.S. Industries and Establishments
This paper examines the effect of a change in U.S. trade policy on the domestic investment of U.S. manufacturers. Using a difference-in-differences identification strategy, we find that industries more exposed to reductions in import tariff uncertainty exhibit relative declines in investment after the change in trade policy. Within industries, we find that this relationship is concentrated among establishments with low initial levels of labor productivity, capital intensity and skill intensity. For plants with high initial levels of skill intensity, we find that increased exposure is ...
How Much Will the Belt and Road Initiative Reduce Trade Costs?
This paper studies the impact of transport infrastructure projects of the Belt and Road Initiative on shipment times and trade costs. Based on a new data on completed and planned Belt and Road transport projects, Geographic Information System analysis is used to estimate shipment times before and after the Belt and Road Initiative. Two sets of data are computed to address different research questions: a global database based on an analysis of 1,000 cities in 191 countries and 47 sectors and a regional database that focuses on more granular information (1,818 cities) for Belt and Road ...
