This paper develops and estimates a structural model of the labor market for accountants that integrates forward-looking lifetime occupational choices with oligopsonistic employer demand. Using longitudinal resume data covering career transitions of business graduates across six sectors (Big 4, non-Big 4, internal accounting, finance/consulting, technology, and other), we specify a discrete choice dynamic programming model in which workers accumulate sector-specific skills while considering monetary and non-monetary factors, and employers compete for talent under imperfectly elastic labor supply. Estimates indicate that accounting labor markets are characterized by economically significant markdowns (the gap between a worker’s marginal product and their wage) and entry barriers. Counterfactual analyses suggest that reducing employer market power and, to a lesser degree, eliminating entry barriers would increase accountants’ lifetime career values and improve (labor) resource allocation across sectors.
