  • 详情 Does Air Pollution Cause a Reduction of Housing Prices? New Evidence Using Central Environmental Protection Inspection as a Quasi-Natural Experiment
    This paper investigates the causal effects of air pollution on housing prices in China using a dataset of 65 cities from 2014 to 2021. We employ the central environmental protection inspection (CEPI) as a quasi-natural experiment for air pollution index to show a negative causal relationship between air pollution and housing prices. We also find that this causal relationship is more pronounced for less-developed, manufacturing-intensive and tourismrelied cities. Our results reveal the response to central environmental protection inspection on improvement in regional air pollution protection but its by-effects on housing markets, as the impact is limited if the inspection is conducted repeatedly, suggesting its unsustainability as a regulatory tool.
  • 详情 The Political Economy of Corporate Finance: Evidence from ‘Re-nationalization’ in China
    We investigate the power structure of the Chinese political system and explore its implications on corporate finance. With a large sample of firms from 1999-2007, we document large-scale ‘re-nationalization’—local governments re-establish controlling ownership stakes in previously privatized firms. We find that firms located in provinces with newly appointed, top-ranked Party leaders who do not belong to any of the three dominant political factions are more likely to be renationalized. With a number of instrument variables, including the political status of the top-ranked provincial party leaders, we find that re-nationalization leads to lower sales and labor productivity for the firms. We also find some evidence that re-nationalization temporarily lowers the unemployment rate in the region without any significant, long-term economic benefits.
