A positive correlation between insurance coverage and ex post risk can be an indicator for private information in insurance markets. However, this test fails if agents have heterogeneous risk attitudes. We propose a new test that conditions on unobserved types of individuals who differ in their...

At the end of 1998, China launched a government-run mandatory insurance program, the Urban Employee Basic Medical Insurance (UEBMI), to replace the previous medical insurance system. Using the UEBMI reform in China as a natural experiment, this study identify variations in patient cost sharing...

The effects of different anti-reflective structures on the photovoltaic performance of the silicon solar cell were studied using finite-element modelling and numerical simulations for which experiment alone does not provide a full description. The front surface reflectivity may be mitigated...

We use China's large-scale reform of state-owned enterprises (SOEs) in the late 1990s as a natural experiment to identify and quantify the importance of precautionary saving for wealth accumulation. Before the reform, SOE workers enjoyed the same job security as government employees. Since the...

This paper examines the effect of the supplier’s customer geographic proximity on its tax avoidance. Based on a sample of 4,774 firm-year observations from 2009 to 2019, we find that the supplier’s customer geographic distance is positively associated with the extent of its tax avoidance....
