Abstract

Conventional measures of openness are based on direct trade. They imply foreign shocks are irrelevant to sectors that do not trade directly across borders, e.g., services. But shocks propagate via the supply chain: Sectors that trade indirectly across borders via downstream linkages are affected by foreign shocks. We introduce a measure of openness based on indirect trade, computing the fraction of downstream linkages that cross a border. The measure, labeled “High Order Trade” (HOT), is computed using recently released data on international input-output linkages for 50 sectors in 43 countries, including services. HOT correlates positively with conventional trade measures across countries, much less across sectors as many more are open according to our measure. Some services are among the most open sectors in some economies, and services generally rank at the middle of the distribution. HOT correlates significantly with sector productivity, growth, and synchronization; conventional measures of trade do not. We introduce an instrument for HOT using network theory. We show HOT causes productivity and synchronization, but not growth.
