The author analyzes production and labor market data for a random selection of small to medium-size firms in Ethiopia to answer two questions: 1) Does a worker's marginal productivity increase with time in the labor market or with job security, as must be the case if on-the-job skill formation or job matching has anything to do with the dynamics of wages observed in the data? 2) Assuming that marginal productivity grows with experience or seniority, is skill formation more or less important than job matching as a source of growth in productivity? The main feature of the author's analysis is the joint regression of the log of the average product of hours in a firm and the log of average hourly earnings of a firm's employees on the shares of experience-seniority cells of workers in total annual hours in the firm. Marginal productivity falls as experience in the labor market passes the 15-year mark, but the expected marginal product of a mobile worker with 16 or more years of experience is still nearly 80 percent higher than that of the base group.
