Trade-in-goods and trade-in-tasks: An integrating framework

We introduce a simple but flexible analytical framework in which both trade in goods and trade in tasks arise. We use this framework to provide versions of the gains-from-trade and the famous four HO theorems (Heckscher-Ohlin, factor-price-equalisation, Stolper-Samuelson, and Rybczynski) that apply to this environment. We extend our framework to accommodate monopolistic competition and two-way offshoring and to integrate theoretical results of the early offshoring literature. (C) 2013 Elsevier B.V.
