The costs of refocusing: Evidence from hedge fund closures during the financial crisis
利用2007-2009年金融危机期间被迫关闭基金的对冲基金数据，研究发现业务范围缩减（聚焦调整）会给企业带来显著的经济成本，且关闭的业务与姐妹部门关联越紧密，成本越大且越持久。
Research Summary This paper investigates the costs of corporate scope reduction (“refocusing”). Using data on hedge fund firms that were quasi‐exogenously driven to close funds during the 2007–2009 financial crisis, we find evidence that refocusing imposes meaningful economic costs on firms. To better understand the mechanisms behind this result, we disaggregate refocusing costs along two dimensions: the degree of relatedness between the business that was closed and its sister divisions, and the duration of time over which the costs persist. The results suggest that refocusing imposes meaningful, yet transitory, adjustment costs on firms, and destroys synergies when related businesses are closed, creating more persistent costs. Accordingly, our work contributes to the corporate strategy literature by characterizing and evaluating the costs of refocusing. Managerial Summary We examine the costs of “refocusing,” defined as multi‐business companies reducing the number of businesses they operate. Using data on hedge funds that were driven to close one or more of their funds during the 2007–2009 financial crisis, we show that refocusing imposes meaningful economic costs on companies. We find that refocusing costs are larger and persist for longer when the business that was closed is more closely related to other businesses within the company. Together, our results suggest that refocusing may destroy synergies and be difficult for organizations to manage. This implies that managers should take steps to mitigate the dislocations that may occur as the refocusing process unfolds, as well as the long‐run persistence in synergy destruction when more‐related businesses are closed.
