We find that daily air pollution levels have a significant effect on the decision to purchase or cancel health insurance in a manner inconsistent with rational choice theory. A one standard deviation increase in daily air pollution leads to a 7.2% increase in the number of insurance contracts sold that day. Conditional on purchase, a one standard deviation decrease in air pollution during the cooling-off (i.e. cost-free cancellation) period relative to the order-date level increases the return probability by 4.0%. We explore a range of potential mechanism and find the most support for projection bias and salience.

We study the impact of nationalism and interstate frictions on international economic relations by analyzing market reaction to adverse shocks to Sino-Japanese relations in 2005 and 2010. Japanese companies with high China exposure suffer relative declines during each event window; a symmetric effect is observed for Chinese companies with high Japanese exposure. The effect on Japanese companies is more pronounced for those operating in industries dominated by Chinese state-owned enterprises, whereas firms with high Chinese employment experience lower declines. These results emphasize the role of countries' economic and political institutions in mediating the impact of interstate frictions on firm-level outcomes.

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.

This article examines the impact of a property rights reform in rural China that allowed farmers to lease out their land. We find the reform led to increases in land rental activity in rural households. Our results indicate that the formalization of leasing rights resulted in a redistribution of land toward more-productive farmers. Consequently, output and aggregate productivity increased by 8% and 10%, respectively. We also find that the reform increased the responsiveness of land allocation across crops to changes in crop prices.

We document a negative relation between air pollution during corporate site visits by investment analysts and subsequent earnings forecasts. After accounting for analyst, weather, and firm characteristics, an extreme worsening of air quality from “good/excellent” to “severely polluted” is associated with a more than 1 percentage point lower profit forecast, relative to realized profits. We explore heterogeneity in the pollution-forecast relation to understand better the underlying mechanism. Pollution only affects forecasts that are announced in the weeks immediately following a visit, indicating that mood likely plays a role, and the effect of pollution is less pronounced when analysts from different brokerages visit on the same date, suggesting a debiasing effect of multiple perspectives. Finally, there is suggestive evidence of adaptability to environmental circumstances – forecasts from analysts based in high pollution cities are relatively unaffected by site visit pollution.

We study favoritism via hometown ties, a common source of favor exchange in China, in fellow selection of the Chinese Academies of Sciences and Engineering. Hometown ties to fellow selection committee members increase candidates’ election probability by 39 percent, coming entirely from the selection stage involving an in-person meeting. Elected hometown-connected candidates are half as likely to have a high-impact publication as elected fellows without connections. CAS/CAE membership increases the probability of university leadership appointments and is associated with a US$9.5 million increase in annual funding for fellows’ institutions, indicating that hometown favoritism has potentially large effects on resource allocation.
