This paper investigates the effect of the quantitative easing on bank lending, taking business type of banks (city banks, regional banks, shinkin banks) into consideration. To do this, we use the Vector autoregression(VAR) model with data set after 2001. As a result, we find that the response of bank lending tends to increase with positive shocks to monetary base. Furthermore, we find that the response of lending of regional banks is relatively small.

Unlike the conventional model, this macroeconometric model contains consumption functions and labor supply functions by income class in households based on FIES and links them with corporate activities such as the wage and the employment and the macro economy. Using this model, we analyzed how economic policies, which are an increase of the minimum wage, the income compensation like a tax refund, aids for the pension and the medical expense etc., increase/decrease wages, employment, income, income inequality and the poverty.

The decision of the present generation affects the welfare of future generations. To solve the intergenerational problem, we consider the problem using a model that introduces reciprocity between generations. Then, from experiments, we explore insights about what would happen between generations. It is shown that the succeeding generations conform to the behavior of the preceding generations. Taking the conformity into account, if the predecessors have a high interest in cooperation, the degree of cooperation will increase throughout the generation, while if they have a low interest in cooperation, cooperation will be weak.

This paper empirically explores how multiple job holding affects the desire for occupational mobility in Japan, based on the data from Employment Status Survey in 2002 and 2007. We observe two effects in our empirical results. First, multiple job holding encourages female employees (both full-time and temporary) and male full-time employees to change their main jobs. Secondly, multiple job holders whose main job and second job belong to the same industry category tend to have desire to change their main jobs.
