Public infrastructures require timely investments in maintaining and upgrading the assets to maintain the quality of the service they provide. In Japan, the need for such investment is increasing as many of the infrastructures were constructed in 1970s, which puts them from 21 % to 63 % out of their service life in 15 years. To help identify priority projects we measure the preference of the residents on the services various infrastructures provides across the nation. Using the mixed logit model, we find that a marginal willingness to pay for a decrease of infectious diseases is about 23 yen per household and month. Our results provide the insights for implementing effective maintenance with a limited budget.
