Should I Stay (in School) or Should I Go (to Work)
研究了在人力资本随机积累、市场不完全、内生劳动供给和教育选择作为实物期权的模型中，最优教育补贴和劳动税累进性，发现慷慨的教育补贴和高累进劳动税能带来平均8%的消费等价收益。
I explore optimal education subsidies and progressivity of labour taxes in a model with stochastic human capital accumulation and incomplete markets, endogenous labour supply and an education choice modelled as a real option , where agents choose an optimal number of years to study before starting work. In a purely analytical Baseline model with tight borrowing constraints on students, which leads to a no-trade equilibrium without savings, the government pays for education via transfers to students or – equivalently – via grants to universities. The social welfare-maximising policy features generous education subsidies and highly progressive labour taxes, much more so than currently seen in the US or Europe, and results in an average consumption-equivalent gain of 8%. This result is robust to myriad extensions, including a Quantitative model with relaxed financial frictions where students can borrow to finance their education, and where hence the equilibrium features extensive precautionary saving by workers.
