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...

Digital technology is reshaping workplaces by enabling spatial separation of offices, known as telework, or remote intelligence (RI), and by facilitating automation of service sector tasks via artificial intelligence (AI). This paper is a first attempt to empirically investigate whether AI and...

The standard international tax model is extended to allow for heterogeneous firms when agglomeration forces are important, enabling 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...

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...

A Melitz-style model of monopolistic competition with heterogeneous firms is integrated into a simple NEG 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 productivity...

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...
