Professor Zhao publishes his research in JEDC and JEoA

Kai ZhaoProfessor Kai Zhao has had his paper titled “Social Insurance, Private Health Insurance and Individual Welfare” accepted for publication in the Journal of Economic Dynamics and Control. In this paper, he develops a quantitative dynamic general equilibrium model to evaluate social insurance policies. The main findings of the paper are that means tested social insurance does not only distort saving and labor supply decisions, but also has a large crowding out effect on the demand for private health insurance. However, despite the distorting effects, the net welfare consequence of eliminating social insurance is still negative. In addition, this paper finds that the existence of social insurance as a last resort is a quantitatively important reason why many Americans choose to be uninsured.

Professor Zhao and his coauthor Ayse Imrohoroglu (USC Marshall) have their paper titled “Intergenerational Transfers and China’s Social Security Reform” accepted for publication in the Journal of the Economics of Ageing. This paper grew out of their research agenda on the Chinese economy and its implications for the rest of the world. In it, they find that a model with two-sided altruism is preferred to a standard pure life-cycle model for studying social security reforms in China due to the prevalence of intergenerational links. They show that the implications of several reforms are quantitatively different from what have been found in existing studies using pure life-cycle models.
