Internationalisation, industrial policy and clusters

This paper analyses industrial policy in an open economy hosting an agglomeration consisting of vertically linked upstream and downstream firms. We show that optimal policy towards upstream and downstream industries may typically differ radically in this setting as compared to the case of a closed economy. Internationalisation in terms of international mobility of firms as well as reduced trade costs is found to have significant impact on policy design. We find that in addition to technology and demand characteristics, degree of mobility and level of trade cost are key determinants of tax and subsidy levels.
