In addition, values have also been transformed, and more people are engaged in production activities (labor) without financial rewards such as development of freeware. We investigate labor supply function under the assumption that labor utility is positive and that consuming goods needs consuming time. In this paper, we show that the market equilibrium is not Pareto efficient under the condition that persons to have disutility for labor and persons to have utility for labor coexist. Furthermore, we show that labor supply function decreases in wage rate when time constraint has meaning. This result maintains whether labor has utility or disutility. Therefore, the well-acquainted assumption that labor supply function increases in wage rate depends on the isolated condition that we ignore the fact that consuming goods needs consuming time and time constraint.}, pages = {1--13}, title = {予算制約と時間制約,労働と効用に関する一考察}, volume = {39}, year = {2019} }
