Partical privatisation good, full privatisation better

Given that the current government wants to partially privatise several SOEs the question to ask is, What effect will this have on firm performance? Some insight into this question is offered by a recent paper in the Scottish Journal of Political Economy (Volume 59, Issue 1, pages 1–27, February 2012). The paper "What Drives the Operating Performance of Privatised Firms?" by Laura Cabeza García and Silvia Gómez Ansón argues that the greater the amount of privatisation the better the performance of the firm. Not an entirely surprising result as the full force of market discipline can only be applied if the firm is fully in private hands but it is something for the government to keep in mind. It would suggest that any performance improvements due to the government's privatisation plans will be modest.

The abstract reads,

Using a panel data analysis of Spanish privatised firms, we study how different factors influence the operating performance of divested companies. The results show that it is not privatisation per se but other factors that matter. After controlling for possible sample selection bias related to government timing of divestments, we find that the greater the relinquishment of State control and the smaller the percentage of ownership held by managers and/or employees, the better the firms’ post-privatisation performance. Moreover, privatisations that are accompanied by liberalisation programmes and occur during buoyant economic cycles turn out to be more successful. (Emphasis added.)
