April 2019Trade Wars: What do they Mean? Why are they Happening Now? What are the Costs?
with Robert W. Staiger: w25762
How should economists interpret current trade wars and the recent U.S. trade actions that have initiated them? In this paper we offer an interpretation of current U.S. trade actions that is at once more charitable and less forgiving than that typically offered by economic commentators. More charitable, because we argue that it is possible to see a logic to these actions: the United States is initiating a change from “rules-based” to “power-based” tariff bargaining and is selecting countries with which it runs bilateral trade deficits as the most suitable targets of its bargaining tariffs. Less forgiving, because the main costs of these trade tactics cannot be avoided even if they happen to “work” and deliver lower tariffs. Rather, we show that the main costs will arise from the use of the ...
September 2015Dark Costs, Missing Data: Shedding Some Light on Services Trade
with James E. Anderson, Ingo Borchert, Yoto V. Yotov: w21546
A structural gravity model is used to estimate barriers to services trade across many sectors, countries and time. Since the disaggregated output data needed to flexibly infer border barriers are often missing for services, we derive a novel methodology for projecting output data. The empirical implementation sheds light on the role of institutions, geography, size and digital infrastructure as determinants of border barriers. We find that border barriers have generally fallen over time but there are differences across sectors and countries. Notably, border effects for the smallest economies have remained stable, giving rise to a divergent pattern across countries.
