Randomized field experiments designed to better understand the production of human capital have increased exponentially over the past several decades. This chapter summarizes what we have learned about various partial derivatives of the human capital production function, what important partial...

This paper is the first to use a randomized trial in the US to analyze the short- and long-term educational and employment impacts of an after-school program, the Quantum Opportunity Program, that offered disadvantaged high-school youth: mentoring, educational services, and financial rewards...
