Which firms find it optimal to integrate their input suppliers into the firm boundaries of control (vertical integration)? Which firms choose to expand their sourcing activities across the national border (offshoring)? This letter provides novel evidence on these questions based on a Spanish...

We analyze the sourcing strategies of firms active in the Spanish manufacturing sector. We show that firms that select strategies of vertical integration and of foreign sourcing ex post tend to have been more productive, ex ante, than other firms.

This paper studies the extensive and intensive margins of firms' global sourcing decisions. We develop a quantifiable multi-country sourcing model in which heterogeneous firms self-select into importing based on their productivity and country-specific variables. The model delivers a simple...

We investigate the role of a firm's total factor productivity in its decision to import from their affiliates rather than from independent input suppliers. We propose a slightly modified version of the Antràs and Helpman (2004) model. We assume higher fixed costs under outsourcing and a...

We investigate the roles of productivity and the specificity of inputs for the international sourcing strategy of firms which are part of a multinational network. We present a framework in which firms decide to import from a foreign independent supplier or from their related party abroad...

We present a North-South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. Based on productivity and sectoral characteristics, firms decide whether to integrate into the...

According to conventional wisdom, multinational firms undertake vertical FDI in order to take advantage of cross-border factor cost differences and source the inputs from abroad at better terms. Recent empirical findings though document that this is not always the case. We provide theoretical...
