Vertical integration, escalating commitment and technological performance: Evidence from firms in the US computer industry

We set out in this study to analyse the impact on the technological performance of firms arising from their vertical integration, along with their escalating commitment to capital investment. Our findings reveal a positive relationship between vertical integration and the technological performance of such firms. A positive correlation is also found to exist between vertical integration and escalating commitment to capital investment; in other words, a firm's rising commitment to its capital investment may well strengthen the positive effects of vertical integration on the technological performance of the firm. More importantly, the interactive effects on technological performance will tend to differ, largely dependent on the type of vertical integration. The findings of this study also indicate that vertical integration can effectively neutralise the threat to exit barriers resulting from a firm's escalating commitment to its prior investment.
