Employment in domestic plants and foreign affiliates: A note on the elasticity of substitution

For a high-wage country like Austria, it is commonly expected that growing employment in foreign affiliates substitutes jobs at home. This paper provides a simple framework for estimating the determinants of relative labor demand (abroad in relation to that at home) bilaterally. It is based on the relationship of (dis)economies and transportation costs under the hypothesis that goods trade is an imperfect substitute for foreign production in the case of horizontal investments, while with respect to vertical investments, goods trade is solely dependent on relative market size. The estimates are based on bilateral industry-level data on foreign affiliates and the domestic activities of Austrian manufacturing firms, covering the period 1990–1996, the 10 most important host countries and 7 industrial sectors.
