| Research Abstract |
In this research, we analyze how the public investment has the effect on the utility of consumers in regional economy.
First, by using the panel data about administrative divisions, our research estimates the influence of social capital on the utility function under the assumption of rational behaviors of firms and individuals. We find clearly that social capital related to residential environment remarkably influences the resident's decision about where to live. On the other hand, we find that the industrial infrastructure does not affect the firms' decision where to locate, but rather the firms tend to locate the densely populated area with a lot of the purchasing power. It is possible that the consumer and the firm have concentrated on the region around Tokyo, because there are abundant in the social capital improving residential environment.
Secondarily, we examine how the optimal allocation of public investment between regions such as roads and railways can be achieved. The optimal allocation of public services can be achieved when the price of public service is equal to the social marginal cost including the congestion externality. We estimate the optimal congestion charge about the railway service, using the data of the JR Chuou Line. By using the relationship between the land price and the commuter's disutility from congestion, we can derive the optimal congestion charge from the land price differentials. According to this, we conclude that it is necessary to impose about 4-5 times the charge in Chuou Line in order to achieve the optimal allocation of public investment. In addition, the congestion charge model of the road is constructed, and the congestion charge is estimated. As a result, we explore how the congestion charge on the vehicle affects the traffic volume in the expressway, and how the environmental burden and the city structure changes.
