Abstract: | The present paper examines a neglected determinant of aggregate productivity: temporary cross-border flows of people. We hypothesize
that interaction between people from different nations facilitates the international diffusion of ideas, thus stimulating
aggregate productivity. In order to assess the causal impact of people flows on productivity, we construct an instrument for
people flows. By analogy to the trade/growth literature, this instrument is derived from a fitted gravity equation involving
geographic determinants of bilateral travel flows. Our cross-section analysis reveal that greater international interaction
leads to higher productivity; a very similar result, qualitatively as well as quantitatively, is obtained when we employ dynamic
panel data methods for the purpose of identification. |
