报告论文:《工资增长、生育率差异与人力资本积累——基于内生生育和退休的动态一般均衡研究》金融研究(2017)
作者:郭凯明、余靖雯
报告摘要:
本文结合我国收入不平等程度较高、计划生育政策放松和工资增速转变等特点,研究了工资增长对劳动力质量的影响。研究表明,生育行为受生育数量和老年闲暇的替代关系影响,低收入群体生育率较高,质量投入较低,退休也较晚,于是工资增长将通过生育率差异影响人力资本积累。通过对转移动态的定量评估,本文建议为缓解社保资金压力,政府应在短期选择延迟退休年龄和提高社会保障税率、在长期选择继续延迟退休年龄和降低社会保障税率的政策组合。

报告论文:《Fiscal Transfers in the Spatial Economy》American Economic Journal: Economic Policy (2021) 作者:Marcel Henkel, Tobias Seidel, and Jens Suedekum
报告摘要:
Many countries shift substantial public resources across jurisdictions to mitigate spatial economic disparities. We use a general equilibrium model with multiple asymmetric regions, labor mobility, and costly trade to carve out the aggregate implications of fiscal transfers. Calibrating the model for Germany, we find that transfers indeed deliver smaller disparities across regions. This comes at the cost of lower national output, however, because economic activity is diverted away from core cities and towards remote areas with low productivity. But despite this loss in output per capita by about 2% in our baseline specification, welfare still increases by 0.07% because the transfer scheme countervails over-congestion in large cities. If the optimal transfer regime was implemented, welfare would increase by 0.06%.
