"Many governments advocate nationwide health insurance coverage but the effects of such a program are less known in developing countries. We use part of the 2006 China Agricultural Census (CAC) to examine whether the recent health insurance coverage in rural China has affected children mortality, pregnancy mortality, and the school enrollment of the 6-16 year old. Our data represent a census of 5.9 million people living in eight low-income rural counties, four of which have adopted the New Cooperative Medical System (NCMS) by 2006 and the other four did not adopt NCMS until 2007. In the counties that offer NCMS, a household may take or not take the insurance. A first look of the data suggests that enrolling in NCMS is associated with better school enrollment and lower mortality of young children and pregnant women. However, using a difference-in-difference propensity score method, we find most of these differences are driven by the endogenous introduction and take up of NCMS, and classical propensity score matching fails to address the selection bias. While NCMS does not show beneficial impacts on the average population, we find some evidence that NCMS helps improve the school enrollment of six-year-olds"--National Bureau of Economic Research web site

Media censorship is a hallmark of authoritarian regimes. We conduct a field experiment in China to measure the effects of providing citizens with access to an uncensored internet. We track subjects' media consumption, beliefs regarding the media, economic beliefs, political attitudes, and behaviors over 18 months. We find four main results: (i) free access alone does not induce subjects to acquire politically sensitive information; (ii) temporary encouragement leads to a persistent increase in acquisition, indicating that demand is not permanently low; (iii) acquisition brings broad, substantial, and persistent changes to knowledge, beliefs, attitudes, and intended behaviors; and (iv) social transmission of information is statistically significant but small in magnitude. We calibrate a simple model to show that the combination of low demand for uncensored information and the moderate social transmission means China's censorship apparatus may remain robust to a large number of citizens receiving access to an uncensored internet.

PurposeThis paper theoretically and empirically analyzes the effects of the elderly's physical health status on their need for care and the choice of care models in China.Design/methodology/approachEmpirically, the estimation results of a large-sample randomized intervention trial with chronic obstructive pulmonary disease (COPD) patients through the difference-in-difference method indicated the following: (1) After the COPD intervention trial, the physical health status of the elderly in the treatment group improved significantly, the need for care was substantially reduced and the health improvement led to a 35.5% reduction in the probability of using elderly care. (2) The reduction in the need for care regarding the treatment group occurred mainly in social care. The probability of using social care decreased by 67.8% due to the elderly's health improvement, while that of home care remained unchanged generally. (3) Further heterogeneity tests suggested that families with fewer potential internal resources for caregiving had a more pronounced decline in the need for social care.FindingsTheoretically, these empirical results support the existence of the "pecking order" theory in the family's choice of elderly care model, that is, families tend to employ all internal resources for caregiving before resorting to social care, resulting in a higher sensitivity of social care to health.Originality/valueThe main policy implication of this paper is that ex ante preventive health intervention policies can significantly alleviate the burden of care, especially social care, on families. And preventive health intervention policies are particularly effective in reducing the burden of the families with relatively few resources for informal internal care.

We report results from a randomized natural field experiment conducted in a restaurant dining setting to distinguish the observational learning effect from the saliency effect. We find that, when customers are given ranking information of the five most popular dishes, the demand for those dishes increases by 13 to 20 percent. We do not find a significant saliency effect. We also find modest evidence that the observational learning effects are stronger among infrequent customers, and that dining satisfaction is increased when customers are presented with the information of the top five dishes, but not when presented with only names of some sample dishes.
