One paper by Steven Haider and Gary Solon challenged the traditional estimation of this quantity using its current analog as a proxy. Joshua Angrist used CWHS data to study the impacts on this quantity from military service and draft avoidance behavior from the Vietnam War draft lottery. The parameter B in a model to estimate this quantity by Gary Becker accounts for changes in physical and intellectual (-5[1])capability. Yoram Ben-Porath adapted that model to estimate this quantity into an individual (*) human capital production function, concluding that maximizing this quantity is equivalent to optimally investing in individual economic growth. Since the late 20th century, most labor economists have decomposed the growth of inequality in this quantity into persistent and transitory components. For 10 points, name this quantity that is, on median, 2.8 million dollars for holders of bachelor’s degrees. ■END■ (0[1])
