讲座题目：Empowering the Elderly – the Effect of Pensions on Eldercare Mode, Brideprice, and Sex Ratio

讲座提要：The paper studies the impact of the New Rural Pension Scheme (NRPS) in China on the eldercare and other family arrangements. The elderly in rural China have low incomes and heavily rely on the eldercare provided by their sons. We analyze how the introduction of the New Rural Pension Scheme (NRPS) empowers the elderly in a difference-in-differences framework. Using the China Health and Longitudinal Study and Chinese Census data, we find that after the NRPS is introduced to the county, adult sons are more likely to migrate out of the parent’s resident county, but adult daughters are not; parents provide less brideprice to their sons when they get married, but the dowry provided to daughters is not affected; and the sex ratio is less biased. In addition, the amount of gift-giving to relatives and friends declines. These results imply that the elderly with pensions are less dependent on the informal care provided by their sons and their relatives and friends. Our findings also suggest that one reason for the son preference is the gain of eldercare provided by a married son and his wife and that is one reason for the son’s parents to pay the brideprice is to “purchase” the eldercare provided by the son couple.

讲座题目：Risk Measures Recovered from Higher-Order Moments and Corresponding Trading Strategies

讲座提要：In this paper we consider estimation of the risk measure proposed by Aumann and Serrano (2008) under two common distribution assumptions: Normal inverse Gaussian (NIG) and Mixture of normals (MN), both depending on the first four moments. While this measure has an analytic form under NIG, it does not under MN. We thus demonstrate how this risk measures can be recovered from the first four moments using calibration when the distribution is MN. In our empirical study, we compute the NIG- and MN-based Aumann-Serrano measures using forward-looking moments and examine how higher-order moments may affect these measures. It is found that, the resulting Aumann-Serrano measures provide quite different risk signals during crisis periods, compared with the conventional measures that do not involve higher-order moments and the Aumann-Serrano measures that utilize incorrect information of higher-order moments. We also construct trading strategies from the NIG- and MN-based measures and show that they significantly outperform other strategies in terms of the annualized and accumulated returns.
