Consider the Grossman-Rossi Hansberg model of offshoring. There are two goods: X and Y. Good X requires 4 units of unskilled labour to do Task 1 and 4 additional units of unskilled labour to do Task 2. Further, 2 units skilled labour is also necessary to organize production of Good X. Good Y requires 2 units of unskilled labour to do Task 1 and 2 additional units of unskilled labour to do Task 2. Besides, 4 units skilled labour is also necessary to organize production of Good Y. The prices of both goods are fixed on world markets at $24 per unit. Initially, all tasks were performed domestically, but now it becomes possible to perform Task 1 in another country (offshoring) for free.
