The magnification effect in global value chains

We examine the “magnification effect,” which demonstrates that as the number of separable production stages increases, trade increases dramatically as trade costs decline. We empirically investigate the existence of this magnification effect by estimating gravity-type equations for worldwide trade to obtain the tariff elasticity of trade per industry. We find that tariff elasticity is higher in industries with a greater degree of global value chain participation. These results are observed for both gross and value-added trade. Furthermore, we find that tariff elasticity is higher in intra-Asian trade, especially in machinery industries.     

The global financial crisis and protectionism: Substitution from tariffs to non-tariff measures

This study empirically investigates the relationships between tariffs and non-tariff measures before and after the global financial crisis (GFC). The panel analysis is based on traded products of 70 countries from 1997 to 2015. For developed countries, we find that tariffs and non-tariff measures were complementary before the crisis, but they became substitutional afterward. We do not find such shift for developing countries. We also run the analysis by income levels and by types of products and observe differential effects of the GFC on the relationship between the two trade policies.     

Competitive pressure and firm investment efficiency: Evidence from corporate employment decisions

This study examines the link between product market competition and labour investment efficiency. We find that competitive pressure distorts the efficiency of corporate employment decisions by creating an underinvestment problem. This finding withstands a battery of robustness checks and remains unchanged after accounting for endogeneity concerns. Additional analysis shows that the relationship between product market competition and labour investment efficiency is stronger for firms facing higher competitive threats, greater financial constraints, higher information asymmetry and higher labour adjustment costs. Our results suggest that as competition increases bankruptcy risk, it leads managers to underinvest in labour to avoid incurring labour-related costs.     

British exports and foreign tariffs: Insights from the Board of Trade's foreign tariff compilation for 1902

This research note contributes to the debate over whether British exports were elastic to foreign tariffs before the First World War. In doing so, this study is the first to make econometric use of the commodity- and country-disaggregated foreign tariff data that Britain's Board of Trade compiled for the year 1902. Contrary to previous literature, British exports were indeed elastic to foreign tariffs across a range of manufactured commodities, with a conservative estimate of the elasticity being 3.1, which is not low by modern standards. Counterfactually, if foreign countries had emulated Britain's policy of free trade in manufactures in 1902, a partial-equilibrium estimate is that British exports would have been 57 per cent higher. If the trade-liberalizing trend of the mid-nineteenth century persisted into the late-nineteenth century, then much of the late-Victorian deceleration of British exports would have been avoided.
