A dominant aspect of ownership in the developing world is pyramidal structures, which allow shareholders to control corporations with relatively low investments. The uneasy relationship between these controlling investors and minority shareholders, and the potential impact on the broader macro economy, has been well studied by corporate governance scholars. On the one hand, the mismatch of cash flow and control rights leads to a range of agency problems and resultant resource misallocations, potentially impacting the macro economy (see Randall Morck, Daniel Wolfenzon, and Bernard Yeung 2005 for a comprehensive overview). Yet pyramids are one important mechanism that enables the formation of diversified business groups that, too, are a dominant feature of business organization in much of the world. The economics and management literature has taken a more ambivalent view of business groups, with their agency problems and rent seeking behaviors often counterbalanced by productive efficiencies from correcting market failures in weak institutional environments (see, in particular, a survey of the business groups literature by Tarun Khanna and Yishay Yafeh 2007 which emphasizes this tension). Often, the channels that enable value extraction by controlling interests overlap with those required to overcome market failures. For example, consider a controlling shareholder of a publicly listed firm that has a separate, completely owned, Trade and The InTernal OrganIzaTIOn Of fIrms

We examine the market response to an unexpected announcement of the sale of government-owned shares in China. In contrast to earlier work, we find a negative effect of government ownership on returns at the announcement date and a symmetric positive effect from the policy's cancellation. We suggest that this results from the absence of a Chinese political transition to accompany economic reforms, so that the benefits of political ties outweigh the efficiency costs of government shareholdings. Companies managed by former government officials have positive abnormal returns, suggesting that personal ties can substitute for government ownership as a source of connections.
