１．Fukuju YAMAZAKI・Yoshihisa ASADA ”Measurement of the Congestion Externality in Rail Commuting in the Tokyo Metropolitan Area”（ＰＤＦfile）

We developed an econometric model for estimating congestion costs in rail travel. Congestion charges have been estimated by using data obtained from the rent functions for the railways in the Tokyo metropolitan area. Paying attention to the rent gradient, in which the external effects of congestion should be reflected, we included the congestion rate as an explanatory variable in the estimation equation for the rent differential. We found that congestion rates have a significant and positive effect on differences in rents. By using the estimated coefficient, we found that congestion charges are between 2.05 and 9.59 times the fares.

２．Fukuju YAMAZAKI・Yoshihisa ASADA ”Tenure Choice and User Cost for Housing”（ＰＤＦfile）

We present a model that determines both the discrete tenure choice and continuous demand for floorspace simultaneously, introducing agency costs into rental market and transaction costs into owner occupation, respectively.First, we show that while consumers of higher income prefer larger housing in owner occupied market, consumers of lower income choose smaller housing in rental market.Second, we examine how the user cost of housing capital, the transaction cost and the agency cost respectively affect the lot size of housing and the rate of owner occupation. Third, we empirically examine whether our model can explain the tenure choice, using the data of housing market in Tokyo.
