Subway, Collaborative Matching, And Innovation, Yumi Koh, Li Jing, Jianhuan Xu

Expansion of subway networks helps to enhance connectivity and matches of people by facilitating their mobility. Using rapid expansion of the Beijing subway from 2000 to 2018, we analyze its impact on collaborative matches in innovations. We find that an hour reduction in travel time between a pair of locations in Beijing brought a 15% to 38% increase in collaborated patents. Far-apart location pairs were more affected, and the local average treatment effect is approximately 35% to 82%. Such effect is mainly driven by increased matches among highly productive inventors due to complementarity between inventors’ productivity and travel time. At …
Informal Institutions And Comparative Advantage Of South-Based Mnes: Theory And Evidence, Pao-Li Chang, Yuting Chen
Informal Institutions And Comparative Advantage Of South-Based Mnes: Theory And Evidence, Pao-Li Chang, Yuting Chen
Research Collection School Of Economics
This paper builds a theory based on “informal institutions” to characterize the comparative advantage of South-based MNEs. MNEs headquartered in countries with poorer state institutions are shown to endogenously invest more in firm-specific institutional capital to compensate for the lack of state institutions, and as an optimal response, undertake FDI in countries with weaker institutions. We conduct an extensive test of the theory using worldwide firm-level greenfield FDI flows during 2009–2016, employing (among others) variations in the interaction of prevalence of informal institutions at home and state institutional qualities of host countries, as well as heterogeneity across sectors and firms …
Public Health Insurance And Pharmaceutical Innovation: Evidence From China, Xuan Zhang, Huihua Nie
Public Health Insurance And Pharmaceutical Innovation: Evidence From China, Xuan Zhang, Huihua Nie
Research Collection School Of Economics
Developing countries are characterized by low levels of pharmaceutical innovation. A likely reason is their small market size, which is not because of the population size but because of low levels of income and lack of health insurance coverage. This study exploits a natural experiment from the implementation of a public health insurance program for rural residents in China (New Cooperative Medical Scheme [NCMS]) to examine whether the pharmaceutical industry increases innovation regarding diseases covered by the NCMS that are prevalent in rural areas. We examine the 1993–2009 patent data to gauge pharmaceutical innovation in China. Diseases with a 10% …
