We use dynamic panel data models to generate density forecasts for daily Covid-19 infections for a panel of countries/regions. At the core of our model is a specification that assumes that the growth rate of active infections can be represented by autoregressive fluctuations around a downward...

The surprise economic shutdown due to COVID-19 caused a sharp improvement in urban air quality in many previously heavily polluted Chinese cities. If clean air is a valued experience good, then this short-term reduction in pollution in spring 2020 could have persistent medium-term effects on...

China's environmental regulators have sought to reduce the Yangtze River's water pollution. We document that this regulatory effort has had two unintended consequences. First, the regulation's spatial differential stringency has displaced economic activity upstream. As polluting activity...

Several Chinese cities have invested billions of dollars to construct new industrial parks. These place based investments solve the land assembly problem which allows many productive firms to co-locate close to each other. The resulting local economic growth creates new opportunities for real...

Urban China's high levels of ambient air pollution both lowers quality of life and raises mortality risk. China's wealthy have the purchasing power to purchase private products such as portable room air filters that allows them to offset some of the pollution exposure risk. Using a unique data...

China's rapid economic growth has been fueled by industrialization and urbanization. Given its export focus, this industrialization was spatially concentrated in the coastal eastern cities. Over the last decade, a spatial transformation has taken place leading to a deindustrialization of the...

At political boundaries, local leaders often have weak incentives to reduce polluting activity because the social costs are borne by downstream neighbors. This paper exploits a natural experiment set in China in which the central government changed the local political promotion criteria and...

China's extremely high levels of urban air, water and greenhouse gas emissions levels pose local and global environmental challenges. China's urban leaders have substantial influence and discretion over the evolution of economic activity that generates such externalities. This paper examines the...

In Beijing, the metropolitan government has made enormous place based investments to increase green space and to improve public transit. We examine the gentrification consequences of such public investments. Using unique geocoded real estate and restaurant data, we document that the construction...

With the decline of the traditional hukou system, migrants in China have a broad set of cities to choose from. Within an open system of cities, compensating differentials theory predicts that local real estate prices will reflect the marginal valuation of non-market local public goods. More...
