Note: This table provides descriptive statistics for the variables used in the regressions below. CF is a shorthand for the “count of firm-to-firm links”; PTA stands for Preferential Trade Agreements; Total depth is the PTAs' Depth; Core depth is the PTAs' core depth (WTO+ plus competition policy, investment, movement of capital, and intellectual property rights); WTO-X depth is the PTAs' WTO-X depth (provisions beyond the current World Trade Organization mandate); BIT stands for Bilateral Investment Treaties; Backward and Forward measure the average input and output coefficient, respectively; Input specificity affiliate/parent measures the degree of differentiation of the goods produced by the sector.
