Age, Health and the Willingness to Pay for Mortality Risk Reductions: A Contingent Valuation Survey of Ontario Residents

Abstract: A contingent valuation survey was conducted in Shizuoka, Japan, to estimate the willingness to pay (WTP) for reductions in the risk of dying and calculate the value of statistical life (VSL) for use in environmental policy in Japan. Special attention was devoted to the effects of age and health characteristics on WTP. We find that the VSLs are somewhat lower (103 to 344 million yen) than those found in a virtually identical survey applied in some developed countries. These values were subject to a variety of validity tests, which they generally passed. We find that the WTP for those over age 70 is lower than that for younger adults, but that this effect is eliminated in multiple regressions. Rather, when accounting for other covariates, we find that WTP generally increases with age throughout the ages in our sample (age 40 and over). The effect of health status on WTP is mixed, with WTP of those with cancer being lower than that of healthy respondents, while the WTP of those with heart disease is greater. The VSLs for future risk changes are lower than those for contemporaneous risk reductions. The implicit discount rates of 5.8%–8.0% are relatively larger than the discount rate regularly used in environmental policy analyses. This survey is the first of its kind in Japan, and provides information that is directly useful for estimating the benefits of environmental and other policies that lower mortality risks to the general population and subgroups with a variety of specific traits.

Public Transport Subsidies and Affordability in Mumbai, India

Abstract: This paper describes the role of public transport and the nature and incidence of transport subsidies in Mumbai, India. Mumbai has an extensive rail and bus network, and public transport is used for over 75 percent of all motorized trips in Greater Mumbai. Both rail and bus fares in Mumbai are subsidized: BEST, which operates public buses in Mumbai, is also an electric utility, and subsidizes bus fares from electricity revenues. We analyze the incidence of these subsidies, and their effect on mode choice, using data from a survey of households in Greater Mumbai. In Mumbai, as in many cities, the middle class is more likely to use public transport for travel than the poor. The poor, however, also use public transit, and their expenditure on public transit constitutes, on average, a larger share of their income than it does for the middle class. It is, therefore, the case that the poor benefit from transit subsidies in Mumbai, as well as the middle and upper-middle classes; however, the poorest 27 percent of the population receives only 19 percent of bus subsidies and 15.5 percent of rail subsidies. Indeed, 26 percent of the lowest income households surveyed do not use rail, while 10 percent do not use bus, implying that they receive no transit subsidies. Expenditure on transport accounts for 16 percent of income in the lowest income category ( Expenditure on public transport would be even higher if bus fares in Mumbai were not subsidized. In 2005-2006, transport revenues of BEST fell below total costs by 30 percent and below operating costs by 20 percent. Rail fares, which are much lower than bus fares per km traveled, officially covered operating costs and almost covered depreciation expenses.

Expenditure on transport accounts for 16 percent of income in the lowest income category (<5000 Rs./month), with 10 percent of income, on average, spent on bus and rail fares. This percentage, however, is not evenly distributed: it is much higher than 10 percent for households in which workers take the bus or train to work, and lower for households in which the main earner walks to work. Even in these households, however, 12.5 percent of income is spent on transportation. Expenditure on public transport would be even higher if bus fares in Mumbai were not subsidized. In 2005-2006, transport revenues of BEST fell below total costs by 30 percent and below operating costs by 20 percent.
