Abstract: | This paper examines the impact of public infrastructures on the performance of Spanish private business at a disaggregated industry level. We use duality theory to recover the productivity effects of public capital by calculating the cost saving effects that are associated to public services. Using a translog cost function we present panel estimates for 14 Spanish industries during the period 1980–1991. Our results strongly suggest that public capital formation can be considered to be an instrument to improve competitiveness by reducing production costs. However, the results also indicate that there is a technologically induced labor saving effect through higher public investment. Furthermore, our estimates suggest that a distinction among industries is of importance because the effects of public infrastructures vary across industries considerably. |
