Foreign direct investment, agglomerations, and demonstration effects:: An empirical investigation

Previous studies have shown that the localisation of firms can be an important factor in attracting new foreign direct investment into a host country. The authors distinguish between "efficiency agglomerations" which arise as firms increase their efficiency by locating close to each other, and "demonstration effects" whereby existing firms send signals to new investors as to the reliability and attractiveness of the host country. They try to disentangle these two effects by examining the location of US firms in Ireland. They find that both sources of agglomerations have been important determinants of US firm entry into Ireland. JEL no. F23.
