Let mvpi be the marginal value product for worker i, which is the price of a firm's good multiplied by the marginal product of the worker. Assume that
log(mvpi) = β0 + β1 xi1 + ... + βk xik + u.
wagei = max (mvpi, minwagei),
where the explanatory variables include education, experience, and so on, and minwage. is the minimum wage relevant for person i. Write log(wagei) in terms of log(mvpi) and log(minwagei).
