RESTREPO, Jorge Alberto. EXTERNALIDADES EN LA INDUSTRIA COLOMBIANA. Cuad. Econ. [online]. 2000, vol.19, n.33, pp.171-189. ISSN 0121-4772.

A test of the Caballero-Lyons [1989] model of external effects in manufacturing is performed with a gross output and value added data set of 28 two-digit industries for Colombia, using panel data estimation techniques. Both at aggregate and at industry level there is no evidence of economies of scale. At industry level there is a positive aggregate externality that ranges from 0.38% to 0.25% tor a one-percent increase in aggregate manufacturing activity. The etfect af effort, capacity utilisation or policy regimes does not seem to affect significantly these results.
