Factors determining residents’ preparedness for floods in modern megalopolises: the case of the Tokai flood disaster in Japan

This study examines how flood risk perception and home ownership affect residents’ preparedness for floods, focusing specifically on the case of the Tokai flood disaster in Nagoya City, one of Japan’s biggest metropolises, in 2000. The greatest rainfall ever recorded in Nagoya City (566.5 mm) occurred on 11–12 September 2000; as a result, a local river burst its banks and flooded the city. A survey was conducted of residents of the affected area in Nagoya City and its adjacent region. The respondents were asked to rate the extent of their experience with, anticipation of, and preparedness for floods before and after the Tokai disaster in terms of taking special measures against floods. The results showed that the degree of preparedness for floods was determined by the level of fear of floods and the amount of damage sustained during the Tokai flood, especially for homeowners. However, the residents’ preparedness did not depend on their anticipation of floods. These findings show that preparedness for floods depends on ownership of a home, fear of flooding, and the amount of damage from previous floods rather than on previous experience with and anticipation of floods.     

A simple dynamic decentralized leadership model with private savings and local borrowing regulation

This paper considers a simple dynamic decentralized leadership model with local borrowing and regional productivity-enhancing investment. In this model, the central government is benevolent but cannot commit to ex post intergovernmental transfer policies, while local governments act strategically after accounting for the ex post motives of the central government. We then investigate inefficiency in the subgame perfect equilibrium. We analyze the effect of central control on local borrowing and show that central control is of no benefit because ex ante local taxation works to offset it. We find the model yields different policy implications that central control is effective when extended to the case of residential mobility.     

Too big or too small? A synthetic view of the commitment problem of interregional transfers

There is a growing body of literature on the commitment problem of interregional transfers. The problem occurs because of an ex post bailout by a central government leading to ex ante adverse incentive consequences for a local government. However, different models have yielded different economic consequences. The local government may be too large, overspending and/or overborrowing, or it may be too small, raising less of its own revenue. In the presence of interregional spillovers, the equilibrium may yield a Pareto-efficient outcome. The present paper aims to synthesize these models, developing a simple decentralized leadership model. A critical question concerns what decision is made ex ante by the local government—namely public expenditure or tax collection—with the remaining policy instrument being residual adjusted by ex post transfers. We discuss how different scenarios affect the equilibrium outcome.     

The Optimality of Punishing Only the Innocent: The Case of Tax Evasion

We study the effectson tax enforcement and tax policy of unintentional complianceerrors by taxpayers and administrative errors by tax auditors.The government can impose both penalties for misreporting andrewards for honest reporting. Maximal sanctions will not be appliedbecause errors are possible, so evasion cannot be eliminatedcostlessly. Under optimal policy intentional evasion can be deterred,but innocent tax evaders must be penalized whether they haveunintentionally evaded or have been mistakenly convicted. Thisdeters intentional evasion, but limits redistribution. Withoutrewards for honest reporting, the revelation principle need notapply, so intentional evasion can occur.     

AGGLOMERATION ECONOMIES IN JAPAN: TECHNICAL EFFICIENCY, GROWTH AND UNEMPLOYMENT

This paper examines if the effects of agglomeration economies are manifested in technical efficiency and generate faster economic growth and higher (lower) levels of employment (unemployment). Using the prefecture level data for each of the two-digit groups of industries in Japan, it estimates a region-specific technical efficiency index based on the stochastic frontier production function framework. The factor analysis shows that in most of the industry-groups, efficiency has a positive association with external scale variable(s). Though the relationship is not very strong, it would be erroneous to ignore the effect of agglomeration economies on efficiency. For some light goods industries, the agglomeration effect is relatively stronger. Economic growth varies positively with external scale variable(s) and the unemployment rate tends to fall with respect to growth and concentration. This suggests that measures against industrial concentration may be counter-productive, particularly in the context of globalization when countries greatly need to raise productivity.
