The determinants of corporate divestment in the UK

It has been widely suggested that since the early 1980s many diversified firms narrowed the scope of their activities by refocusing on their core businesses, primarily through divestment activity. This study examines the extent and determinants of divestment across a large sample of UK firms over the period 1985–1989. Divestment is analysed using both a proportions and count data (Poisson and negative binomial regressions) approach. The results confirm that corporate divestment is not merely a reflection of managerial idiosyncrasies or mean reversion behaviour in the activities undertaken, but is a purposeful response to exogenous change in a manner broadly consistent with both the agency theoretic and strategic views of the firm.
