实体杠杆对经济增长的影响研究——基于金融稳定的调节效应

本文以全球43个国家和地区2001-2020年的动态面板数据为研究样本,实证检验不同实体部门杠杆对经济增长的影响差异及作用机制。通过构造金融稳定指数,进一步论证金融稳定对实体杠杆与经济增长之间关系的调节效应。结果表明:实体杠杆与经济增长之间存在“倒U形”关系,不同部门杠杆对经济增长影响的“拐点”有所不同。机制检验发现,居民杠杆、企业杠杆和政府杠杆分别通过“消费”“投资”和“政府支出”渠道影响经济增长;金融稳定性的提升能够正向调节实体杠杆对经济增长的影响,提高实体杠杆对经济增长影响的“拐点”。上述结论对我国经济增长和杠杆调控具有一定政策启示。在经济运行过程中,应充分考虑各部门杠杆异质性,细化实体杠杆的调控方向,进一步优化杠杆结构,以期实现经济增长与金融稳定双重目标下的动态平衡。     

Sense of belonging,international migrants’ spending,and implications for their subjective well-being

A lack of a sense of belonging in the host country has become one of the most common challenges facing international migrants in today's sociopolitical environment. Our two online experiments with 881 international migrant workers in the United States jointly demonstrate that, to cope with their lack of a sense of belonging in the host country, international migrants may spend money suboptimally: more on material purchases but less on experiential and prosocial purchases. More importantly, our studies suggest that prosocial purchases are more effective than experiential purchases in increasing international migrants’ subjective well-being. This is because prosocial purchases can lead to both relatedness need satisfaction and beneficence, with each independently contributing to international migrants’ subjective well-being. Our research suggests that public policymakers should address the social exclusion international migrants experience when moving to a new country because it can have a negative impact on their subjective well-being. Our research further suggests that one way to mitigate social exclusion is to encourage international migrants to spend money on others rather than themselves.
