The authors study the design of optimal unemployment insurance in an environment with moral hazard and cyclical fluctuations. The optimal unemployment insurance contract balances the insurance motive to provide consumption for the unemployed with the provision of incentives to search for a job....

We explore the impact of the lottery enrollment policy, which aims to promote equal and affordable education but introduces private school enrollment uncertainty in China. Using residential housing transaction data from the largest real estate agent in Chengdu during 2018-2020 and controlling...

Background: The role of private health insurance in protecting the population's health is an essential global concern. However, the for-profit nature of private health insurance has led to inequality of opportunity for coverage, which has implications for the health performance of...

Background: During endoscopy, dimension measurement of the object is quintessential in diagnosis, e.g., the necessity and extent of further kidney stone fragmentation. The monocular endoscope lacks enough visual cues to measure accurately in the narrow cavity.Methods: Firstly, a tiny...

A novel electrochemical immunoassay based on nanobody heptamer for ultrasensitive detection of alpha fetoprotein (AFP) is proposed. First, AFP heptamer fusion protein (A1-C4bpa) is prepared via fusing the AFP-specific nanobody (A1) with the C-terminal fragment of C4-binding protein (C4bpa). Then...

Traditional carbonate-based electrolytes are not suitable for high voltage lithium metal batteries (LMBs), which seriously hinders the development of high-energy density LMBs. Here, a novel flame retardant fluorine-rich electrolyte (termed FFT) composed of 1.2 M lithium hexafluorophosphate (LiPF...

This paper examines how asymmetric information affects peer-to-peer lending in China. We find that default rates rise significantly with interest rates. Specifically, borrowers who select interest rates above the legal maximum private lending rate of 15.4% are more likely to default. A lack of...

This paper examine the impact of noise trading on stock liquidity in China. We construct a theoretical model including noise traders, rational traders, and insiders, and test the model using transaction data on individual stocks in the CSI-300 (China-Shanghai-Shenzhen-300-Stock Index) in 2020....

We investigate the competition between banks according to an evolutionary model, in which the payoff gradient depends on a time-variant technological innovation factor. The explicit solutions of equilibrium strategies are derived via the method of characteristics. Advantageous technological...
