Title IV of the 1990 US Clean Air Act Amendments established a market for transferable sulfur dioxide emission allowances among electric utilities. The market offers firms facing high marginal costs for pollution abatement the opportunity to purchase the right to emit sulfur dioxide from firms...

This paper reports the results of a survey of 5,000 households in the Greater Mumbai Region conducted in the winter of 2004. The goal of the survey was to better understand the demand for transport services by the poor, the factors affecting this demand, and the inter-linkages between transport...

The authors examine the impact of local politics and government structure on the allocation of publicly subsidized (SUS) health services across municipios (counties) in Brazil, and on the probability that uninsured individuals who require medical attention actually receive access to those health...

The authors examine the impact of income growth on the death rate due to traffic fatalities, as well as on fatalities per motor vehicle and on the motorization rate (vehicles/population) using panel data from 1963-99 for 88 countries. Specifically, they estimate fixed effects models for...

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...

This paper examines whether the relationship between traffic fatalities and per capita income is the same for different classes of road users and investigates the factors underlying the decline in fatalities per vehicle kilometer traveled (VKT) observed in high-income countries over recent...

The authors compare the welfare effects of in situ slum upgrading programs with programs that provide slum dwellers with better housing in a new location. Evaluating the welfare effects of slum upgrading and resettlement programs requires estimating models of residential location choice, in...

This paper examines the impact of measures to reduce emissions from passenger transport, specifically buses, cars, and two-wheelers in Mumbai. These include converting diesel buses to compressed natural gas (CNG), as the Indian Supreme Court required in Delhi, which would necessitate an increase...

Using plot-level data, the authors estimate a bi-variate probit model to explain land clearing, and the siting of protected areas in North Thailand in 1986. Their model suggests that protected areas (national parks, together with wildlife sanctuaries) did not reduce the likelihood of forest...

The neoclassical theory of project evaluation is based on models in which agents discount the future at a constant exponential rate. But there is strong empirical evidence that people discount the future hyperbolically, applying larger annual discount rates to near-term returns than to returns...
