Abstract: Akerlof created the “psycho-socio-anthropo-economics” to analyze the problem of unemployment by putting forward new economic assumption. Firstly, he proposed the labor heterogeneity assumption and interpreted the unemployment phenomenon as structural unemployment. After absorption of the sociology research results, exchange gifts, fair wages and dual labor market hypothesis, he demonstrated the problem of workers involuntary unemployment. Industrial output depends on the efforts of the workers, and the effort also hinges on the wage level and actual wage level. The difference between the fair wages determines the number of workers employed by enterprises and their efforts. When the labor market is binary, the inexperienced workers will surely become involuntary unemployment. Especially when the job position becomes as a scarce resource, it is hard to utilize the job position best by employing those unskilled and cost-consuming workers. Therefore, even though they would like to accept zero wage, they would not be employed.
