Wage increases, along with job tenure, are one of the most robust empirical regularities found in labor economics. Several theories explain these empirical regularities, and such theories offer sharp empirical predictions for the relation between productivity-tenure and wage-tenure profiles. The human capital model, with cost and benefit sharing between workers and employers, predicts a steeper productivity-tenure profile than wage-tenure profile. The matching quality model predicts that the two profiles will overlap. Theories that involve the information asymmetry between employers and employees predict a steeper wage-tenure profile than productivitytenure profile to induce workers' effort and enhance efficiency. This paper estimates the productivity-tenure profile and the wage-tenure profile by estimating the plant-level production function and the wage equation using employer-employee matched data from Japan. These estimations offer a comprehensive test for the relative applicability of the two theories on the wage-tenure profile. Estimation results indicate a steeper wage-tenure profile than productivity-tenure profile and point to the relative importance of the deferred wage payment contract. |
