Economic freedom and human capital investment
使用109个国家1972-2011年的数据，研究发现经济自由对中学入学率有显著正向影响，可能因为经济自由提高了人力资本投资的回报并便利了信贷。
Abstract Using data from 1972 to 2011 on 109 countries, this paper empirically studies the impact of economic freedom on human capital investment. Enrollment in secondary education is used as a proxy for such investments. Controlling for a large number of other determinants of education, it finds that, over the sample period, economic freedom had a substantial positive effect. This is probably because more economic freedom increases the return on investing in human capital, enables people to keep a larger share of the return, and, by facilitating the operation of credit markets, makes it easier for them to undertake such investments in the first place.
