This paper investigates the role of firm productivity in drawing firm boundaries in global sourcing. Our analysis focuses on how productivity affects the allocation of ownership rights between the headquarter of a firm and its intermediate input supplier (vertical integration vs. outsourcing),...

We use Spanish firm-level data to test the hold-up model of global sourcing proposed by Antr s & Helpman (2004). We propose a novel representation of the model which guides us in bringing the theory to the data. We estimate a discrete choice model of firms' sourcing behavior, separately for the...
