Exploring the Effects of Transportation and Energy Infrastructure on Subjective Well-Being

2016年1月15日 / 12時半~13時半

Kong Joo Shin, Kyushu University

Using data from a large-scale Japanese internet survey collected in June 2015 (n=11,167) this study analysis the relationship between the satisfaction with transportation and energy infrastructure and overall subjective well-being (SWB). Satisfaction with transportation infrastructure is measured by asking respondents how dissatisfied they are with (i) the pavement condition of public roads, (ii) access to public transportation, (iii) traffic congestion of public roads, and (iv) congestion in public transportation. Satisfaction with energy infrastructure is measured by asking respondents their level of satisfaction with utilities (electricity, gas, water, gasoline). Applying logit regressions to our data we obtain the following results: (1) Both aggregated indices of dissatisfaction with transportation and with energy infrastructure have negative effects on overall SWB; (2) the negative impact of both factors declines as household income increases; (3) when transportation variables are analyzed separately, dissatisfaction for public road condition and congestion in public transportation impacts SWB negatively, but only when commuting time is longer than an hour; similarly, congestion of public road affects SWB negatively on its own but the impact declines as commuting time increases; finally, (4) the monetary value of satisfaction with energy utilities is approximately 200,000 yen per year.
