Working Papers

Global Supply Chains, Trade Agreements and Rules of Origin (Job Market Paper)

Free Trade Agreements (FTAs) usually come with restrictions on the use of intermediate inputs in order for final goods to qualify for free trade. I focus on Rules of Origin (RoO), which limit expenses on nonmember country's intermediate inputs. In a three-country FTA formation game, I introduce international trade in intermediate inputs and RoO restrictions. In the case of symmetric countries, I show that as countries become more involved in global supply chains, measured by their input shares in foreign final goods production, global free trade is less likely to be a stable equilibrium outcome. Free riding is the main problem preventing countries from liberalizing trade. Countries are better off being nonmembers of FTAs between the other two countries relative to global free trade. Rules of Origin can solve this problem by limiting the benefits countries get from other countries' free trade agreements. In the case of asymmetric countries, an additional incentive exists for the smaller country not to join: such a country gives up more than it gains from joining an FTA for a sufficiently high degree of asymmetry in country sizes. I show that global free trade is a stable Nash Equilibrium under a larger region of asymmetric country parameter space in the case of RoO than without it. Therefore, it is shown that RoO is essential in order to attain global free trade.


Trade Restrictions and Labor Productivity: Evidence from the Georgian Wine Industry

Russia, the Republic of Georgia's largest neighbor and trading partner, started imposing economic sanctions on Georgia beginning in early 2006, by restricting the import of Georgian wine to Russia. I exploit this natural experiment to estimate the effects of the embargo on the Georgian wine industry. I show that the trade ban actually increased the productivity of wine producers. Not only did average labor productivity increase during the embargo the entire productivity distribution shifted to the right. The reason Georgian firms became more competitive is that they had to export to relatively more competitive markets in US and Europe. The following two main sources of improvement happened to be important. First, firms substantially decreased their employment during the embargo as they let least productive workers leave. And second, the expenses on the intermediate inputs per liter of wine increased dramatically during the embargo, which led firms to produce better wine. The embargo positively affected exporters' productivity. But, more interesting is the fact that embargo did (indirectly) affect domestic producers significantly. This can be explained by the fact that non-exporters were competing with highly productive exporters in the domestic market. This way the embargo positively affected the productivity of the whole industry.
