Health Care Utilization and Health Status of NCMS Elderly Enrollees in China: Evidence from CHARLS Data
By Amy Li and Pengpeng Wang
This study explores the effect of benefit designs and demographic factors on health care utilization and health status of elderly rural enrollees in the New Cooperative Medical Scheme, a rural health insurance program implemented by the Chinese government in 2003. Using the new data from CHARLS pilot study, we find that immediate reimbursement does not have a statistically significant effect on health utilization as suggested in a previous study, but instead on health status. Other policy-related factors neither have a significant effect due to limited data and large standard deviation nor display a consistent effect.

Possibility of Cost Offset in Expanding Health Insurance Coverage: Using Medical Expenditure Panel Survey 2008
By Catherine Moon
The Patient Protection and Affordable Care Act aims to substantially reduce the number of the
uninsured over time and asserts that the financial burden of extending insurance coverage to the
previously uninsured will be offset by the benefit of the attendant improvement in their health.
Motivated by this policy, I explore whether health-insurance status and type affect one’s likelihood of
improving or maintaining health using the Medical Expenditure Panel Survey data. I build a set of
ordered regression models for health-status transitions under the first-order Markov assumption and
estimate it using maximum likelihood estimation. I perform a series of likelihood ratio tests for pooling to determine whether the latent propensity index is the same between adjacent initial health-status groups. Empirical results imply that expanding health care to the unwillingly uninsured due to severe
economic constraints and extending the scope of public insurance to that of private insurance will lead to improvement or maintenance of health for the relatively healthy population, implying the possibility of cost off-set in the expansion of coverage and the extension of scope.
