摘要：We study the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple incomplete contracts model. Then, we investigate these predictions using plant-level data for the UK manufacturing sector. Most importantly, and consistent with the theoretical predictions, we find that the technology intensity of downstream (producer) industries is positively correlated with the likelihood of ...
