Product-Level Trade Elasticities

The paper estimates trade elasticities at the product level (6-digit of the Harmonized System comprising more than 5,000 product categories) by exploiting the variation in bilateral applied tariffs for each product category for the universe of available country pairs. This is done by constructing a panel of bilateral applied tariffs and bilateral trade covering the period 2001 to 2016. We address potential endogeneity issues as well as heteroskedasticity and selection bias due to zero flows. The obtained elasticities are centered around -6. We finally highlight the differences in the gains from trade arising from considering heterogeneous rather than average trade elasticities. All product level elasticities are made publicly available for sake of scrutiny and use by other researcher>>ClickHere>>>

rom Theory to Policy with Gravitas: A Solution to the Mystery of the Excess Trade Balances

Bilateral trade balances often play an important role in the international trade policy debate. Academic economists understand that they are misleading indicators of competitiveness and of the gains from trade. However, they also recognize their political relevance, calling for accurate statistical measurement and for more scholarly work. Disturbingly, Davis and Weinstein (2002) argue that the canonical gravity model of trade fails when confronted with bilateral trade balances data, dubbing this “The Mystery of the Excess Trade Balances”. Capitalizing on the latest developments in the theoretical and empirical gravity literature, we demonstrate that the workhorse international trade model actually performs well in explaining bilateral trade balances. Moreover, in our data, only 11 to 13% of the variance in bilateral balances is due to asymmetric trade costs, belying beliefs that bilateral imbalances are driven by ‘unfair’ manipulation of terms-of-trade. We also perform several general equilibrium experiments within the same structural gravity framework to show that free trade agreements tend to exacerbate bilateral imbalances and that macroeconomic rebalancing leads to adjustment with all trade partners>>ClickHere>>>
