"Land Tenure Security and Home Maintenance: Evidence from Japan"

This paper considers two land tenure modes. leasehold and freehold. and models housing maintenance incentives under land tenure security in Japan. Compared with freeholders, leaseholders are equally likely to remain in the premises, but spend less on home maintenance, because leaseholders are not full residual claimants, even under land tenure security. The empirical results show that maintenance expenditures of leaseholders are about 30% lower than those of freeholders in the Japanese residential land market. Empirical evidence also indicates that leaseholders are equally likely to remain in their premises even when they undermaintain their dwellings.

Dissipative dynamics of non-interacting fermion systems and conductivity

In this paper, Non-Equilibrium Steady State induced by electric field and the conductivity of non-interacting fermion systems under the dissipative dynamics is discussed. The dissipation is taken into account within a framework of the quantum dynamical semigroup introduced by Davies (1977). We obtain a formula of the conductivity for the stationary state, which is applicable to arbitrary potentials. Our formula gives a justification of an adiabatic factor which is often introduced in practical calculation using Kubo formula. In addition the conductivity of crystals (i.e. periodic potentials) is also discussed

The impact of crime on housing land prices and the effects of police boxes and voluntary groups on crime prevention in Japan

Many people now fear crime in Japan, which has had the image of being a safe country, because the crime rate has increased dramatically and the rate of crime detection has decreased at the same time. As demand for low-crime residential areas becomes stronger, low-crime rates may affect land prices in Japan. High levels of land prices may reflect the high economic value of low-crime neighborhoods. However, the Ordinary Least Square (OLS) estimate may cause a bias because the crime rate is not necessarily an exogenous determinant of land price. Therefore, in this study, we adopt the instrumental variable (IV) method, and use instrumental variables such as distance from police boxes and existence of voluntary anti-crime groups, and analyze the effects of property crime rates on residential land prices. The results show that a 10% decrease in the rate of burglaries causes an average rise in residential land prices of 1%.Property Crime, Police box, Voluntary crime-prevention group, Instrumental Variable, Propensity Score Matching

Decomposition Analysis of the Household Migration

The purpose of this research is to show the trends and feature of household migration using the microdata in Housing and Land Survey of Japan (at 1993, 1998, 2003, 2008). We screen the effective observation data and examine the variation of the attribute of moving or staying household with regard to age, type of employment, income, housing tenure, residence performance and so on. We characterize the variation in the ratio of household mobility through the decomposition the variation of age distribution (VAD) and the variation of propensity to move (VPM). Drop of the ratio of household mobility is dominated by VAD on the basis advancing aging society. There is the cases that VPM are increasing even if the ratio of household mobility is declining as a whole tendency
