Longitude matters: Time zones and the location of foreign direct investment

Using bilateral foreign direct investment (FDI) data, we find that differences in time zones have a negative and significant effect on the location of FDI. We show that this finding is robust across different specifications, estimation methods and proxies for time zone differences. Time zones also have a negative effect on trade, but this effect is smaller than that on FDI. Finally, the impact of the time zone effect has increased over time, suggesting that it is not likely to vanish with the introduction of new information technologies. (c) 2006 Elsevier B.V.
