　　报告论文：《Economic policy uncertainty, cost of capital, and corporate innovation》Journal of Banking and Finance，2020 作者：Zhaoxia Xu

　　

　　报告摘要：

　　We examine the impact of government economic policy uncertainty (GEPU) on corporate innovation and identify a cost-of-capital transmission channel. We find that GEPU increases firms’ cost of capital, which translates into lower innovation. As economic policy uncertainty rises, firms with more exposure to such uncertainty face a higher weighted average cost of capital and innovate less. Innovations of financially constrained firms and firms relying on external finance in a competitive environment are affected more. Our study provides novel evidence that higher economic policy uncertainty hinders innovation not only through the traditional investment irreversibility channel, but also through the cost-of-capital channel.

　　报告论文：《Smart Cities: Quality of Life, Productivity, and the Growth Effects of Human Capital》, The Review of Economics and Statistics, 2006  作者：Jesse M. Shapiro

　　

　　报告摘要：

　　From 1940 to 1990, a 10 percent increase in a metropolitan area's concentration of college-educated residents was associated with a .8 percent increase in subsequent employment growth. Instrumental variables estimates support a causal relationship between college graduates and employment growth, but show no evidence of an effect of high school graduates. Using data on growth in wages, rents and house values, this paper calibrates a neoclassical city growth model and find that roughly 60 percent of the employment growth effect of college graduates is due to enhanced productivity growth, the rest being caused by growth in the quality of life. This finding contrasts with the common argument that human capital generates employment growth in urban areas solely through changes in productivity.
