摘要
根据定义,多元化公司由几个部分组成。根据定义,风险投资公司由几个部分组成,即基金,每个部分都有自己的法律身份。由同一家公司管理的基金之间共同投资的可行性,但其中一些专注于技术部门(“专注基金”),而另一些则专注于(达到“专注公司”)或“通才”(达到“多元化公司”),为公司多元化的绩效影响的实证测试提供了独特的机会。研究结果表明,相对于集中型公司,多元化(混合)公司与积极的异常长期退出绩效相关。多元化公司更好地利用了集中基金的投资机会集(集中公司和多元化公司共同持有的机会集)内的积极冲击的到来,这一发现为多元化公司内部资本市场的效率提供了明确的证据。正式的理论预测和实证研究结果表明,虽然公司多元化的绩效效应与内部资本市场的绩效效应一致,但现有的关于多元化溢价与多元化结构的主导地位一致的发现(Santalo and Becerra 2008)缺乏内部资本市场效率的必要条件特征。
Performance Effects of Diversification: Theory and Evidence on Importance of Nature of Information
By definition, diversified corporations consist of several segments. By definition, venture capital firms consist of several segments, that is, funds, each of which has its own legal identity. Feasibility of coinvestments between funds that are managed by the same firm, but of which some are focused (`focused funds') on the technology sector, and others, either focused (for arrival at a `focused firm'), or `generalist' (for arrival at a `diversified firm') provides a unique opportunity for empirical tests of performance effects of corporate diversification. Study findings show, relative to focused firms, that diversified (hybrid) firms are associated with positive abnormal long-run exit performance. The finding that diversified firms take better advantage of arrival of positive shocks within investment opportunity sets of focused funds - an opportunity set held in common by focused and diversified firms - provides unambiguous evidence for efficiency of internal capital markets of diversified firms. Formal theoretical predictions and empirical findings show that while performance effects of corporate diversification align with performance effects of internal capital markets, the extant finding that diversification premiums align with dominance of the diversification structure (Santalo and Becerra 2008) lacks character of a necessary condition for efficiency of internal capital markets.
