PB - National Bureau of Economic Research N1 - February 2013; Hardcopy version available to institutional subscribers N2 - This article reviews the state of the international trade literature on multinational firms. This literature addresses three main questions. First, why do some firms operate in more than one country while others do not? Second, what determines in which countries production facilities are located? Finally, why do firms own foreign facilities rather than simply contract with local producers or distributors? We organize our exposition of the trade literature on multinational firms around the workhorse monopolistic competition model with constant-elasticity-of-substitution (CES) preferences. On the theoretical side, we review alternative ways to introduce multinational activity into this unifying framework, illustrating some key mechanisms emphasized in the literature. On the empirical side, we discuss the key studies and provide updated empirical results and further robustness tests using new sources of data UR - https://www.nber.org/papers/w18775 UR - http://dx.doi.org/10.3386/w18775 ER -
