May 2012Networked FDI: Sales and Sourcing Patterns of Japanese Foreign Affiliates
with Richard Baldwin: w18083
This paper applies a novel empirical approach to characterising the horizontal-ness and vertical-ness of affiliates based on Yeaple’s complex FDI concept. In its simplest form, horizontal-ness is measured as affiliates' local sales share while their vertical-ness is measures as their share of non-local sourcing of intermediates. Japanese affiliates in most sectors and nations are partly vertical and partly horizontal but those in North American are far more ‘horizontal’ than those in the EU and Asia. Affiliates became more vertical between 1996 and 2005. A four-way sales and sourcing split (host, home, regional and RoW) suggests that affiliates act as nodes in regional production networks – especially in Asia. We posit several hypotheses that could be tested with our empirical approach.
January 2011International Trade, Offshoring and Heterogeneous Firms
with Richard Baldwin: w16660
Recent trade models determine the equilibrium distribution of firm-level efficiency endogenously and show that freer trade shifts the distribution towards higher average productivity due to entry and exit of firms. These models ignore the possibility that freer trade also alters the firm-size distribution via international firm migration (offshoring); firms must, by assumption, produce in their ’birth nation.’ We show that when firms are allowed to switch locations, new productivity effects arise. Freer trade induces the most efficient small-nation firms to move to the large nation. The big country gets an ‘extra helping’ of the most efficient firms while the small nation’s firm-size distribution is truncated on both ends. This reinforces the big-nation productivity gain while reducing or ...
June 2009Tax reform, delocation and heterogeneous firms
with Richard Baldwin: w15109
The standard international tax model is extended to allow for heterogeneous firms when agglomeration forces are important thus allowing us to study the relocation effects of taxes that vary according to firm size. We show that allowing for heterogeneity permits a given tax scheme to have an endogenously different effect on the location decision of small and big firms, with the biggest firms being endogenously more likely to relocate in reaction to high taxes. We show that a reform which flattens the tax-firm-size profile can raise tax revenue without inducing any relocation.
October 2005Heterogeneous Firms, Agglomeration and Economic Geography: Spatial Selection and Sorting
with Richard Baldwin: w11650
A Melitz-style model of monopolistic competition with heterogeneous firms is integrated into a simple New Economic Geography model to show that the standard assumption of identical firms is neither necessary nor innocuous. We show that re-locating to the big region is most attractive for the most productive firms; this implies interesting results for empirical work and policy analysis. A 'selection effect' means standard empirical measures overestimate agglomeration economies. A 'sorting effect' means that a regional policy induces the highest productivity firms to move to the core while the lowest productivity firms to move to the periphery. We also show that heterogeneity dampens the home market effect.
