Hong Kong’s franchised buses contribute significantly to its high pollution levels, which in turn result in excess mortality and hospitalizations. I show that replacing all of Hong Kong’s pre-Euro IV buses with cleaner Euro V buses would save 1260 statistical lives, among other benefits. The expected net benefit of such a project is HK$26.4 billion under a discount rate of 3.5%. This result is robust to a discount rate of 10% and a mortality decrease of half of what is expected. This is one of the first studies to estimate the public health impact of air pollution from franchised buses in Hong Kong. The city can therefore consider conducting accelerated replacement of its franchised bus fleet. Given the strongly positive result, other Asian cities with ageing bus fleets could also conduct similar benefit-cost analyses.

The city of Bengaluru, once known as the Garden City of India and the City of Lakes, has now transformed into the Silicon Valley of India. This transformation has happened over the last few decades and has caused major changes to the City’s landscape. One if the important issues the city faces today is the scarcity of water. Researchers owe this issue to the depletion of lakes due to high pollution levels, encroachment and dumping of solid waste in the lakes. The neighborhood Bannerghutta is located in the Southern part of Bangalore Metropolitan Region, which is in developing stages and handful of lakes are found and comes under Minor Irrigation Department. The project focusses on Safeguarding the lake and transforming buffers into public recreational areas with functional strips of riparian vegetation. Safeguarding of lake ensures the habited of that area is preserved and protected. The transformation of lake buffer zones into public recreational spaces ensures the area to be free of any buildings that might otherwise be built on this land. Also, bringing in the public into the space would allow increased public involvement in the lakes campaign and would ensure better maintenance of the functional parts of the lake. A recreational space is perceived as a destination and would add value to the place. Keywords: Safeguarding the lake, developing stages and handful of lakes

In order to be sensible about what discount rate to use one must be clear about its purpose. We suggest that its purpose is to help select those projects that will contribute more net benefits than some other discount rate. This approach, which is after all the foundation for benefit-cost analysis, helps to reconcile different suggested procedures for determining the discount rate. We suggest that the social opportunity cost of capital (SOC) is superior to other suggested approaches in its generality and its ease of use. We use the SOC to determine a range of real rates that vary between 6% and 8%. We suggest that approaches based on determination of preferences, which result in hyperbolic discounting, are less appropriate and less useful.

The reduction of pollutant emissions in the field of transportation can be achieved by developing and implementing electric propulsion technologies across a wider range of transportation types. This solution is seen as the only one that can offer, in areas of urban agglomeration, a reduction of the emissions caused by the urban transport to zero, as well as an increase in the degree of the health of the citizens. This paper presents an analysis of the direct and indirect environmental aspects of a fleet of real electric buses under service in the city of Cluj-Napoca, Romania. The solution of using 41 electric buses to replace Euro-3 diesel buses (with high pollution levels) in the city’s transport system eliminates a local amount of 668.45 tons of CO2 and 6.41 tons of NOx—pollutant emissions directly associated with harmful effects on human health—annually.

In early 1993, the DLWC initiated a project to develop regional planning strategies for clearing and cultivation activities in the Southern Mallee and Northern Floodplain areas of the Western Division of NSW. Concentrating on the Southern Mallee region, a benefit-cost analysis of current clearing and cultivation proposals and their impact on the financial viability of the individual landholder has been conducted. While the development proposals all had the potential to return much higher levels of expected net income to farmers than the existing extensive grazing strategy, market and climatic uncertainty meant that the probability of the extensive grazing activity returning more than cropping was as high as 50% for some proposals. This means that farmers have to weigh up higher incomes on average from cropping against the more certain income from grazing. Clearly, this is a personal choice with the more risk averse decision makers favouring the extensive grazing option. However, we found that for levels of risk aversion that research suggests typifies Australian farmers, the development proposals were dominant over the extensive grazing option except where there was a higher proportion of land devoted to conservation at a discount rate of 12%. No attempt has been made in the present study to evaluate the public benefits and costs, in the form of changes in environmental resources, associated with such development proposals Key words: Western Division, conservation, clearing and cultivation, stochastic dominance, economics.

Regulatory policies designed to improve societal welfare by “nudging” consumers to make better choices are increasingly popular. The application of benefit-cost analysis (BCA) to this sort of regulation confronts difficult theoretical and applied issues. In this analysis we contribute a worked example of behavioral BCA of U.S. anti-smoking policies. Our conceptual framework extends the standard market-based approach to BCA to allow for individual failures to make lifetime-utility-maximizing choices of cigarette consumption. We discuss how our market-based approach compares to the health benefits approach and the “consumer surplus offset” controversy in recent BCAs of several health-related regulations. We use a dynamic population model to make counterfactual simulations of smoking prevalence rates and cigarette demand over time. In our retrospective BCA the simulation results imply that the overall impact of anti-smoking policies from 1964 to 2010 is to reduce the total cigarette consumption by 28%. At a discount rate of 3% the 1964–present value of the consumer benefits from anti-smoking policies through 2010 is estimated to be $573 billion ($2010). Although we are unable to develop a hard estimate of the policies’ costs, we discuss evidence that suggests the consumer benefits substantially outweigh the costs. We then turn to a prospective BCA of future anti-smoking Food and Drug Administration (FDA) regulations. At a discount rate of 3%, the 2010–present value of the consumer benefits 30 years into the future from a simulated FDA tobacco regulation is estimated to be $100 billion. However, the nature of potential FDA tobacco regulations suggests that they might impose additional costs on consumers that make it less clear that the net benefits of the regulations will be positive.

Traditionally, benefit-cost analyses focus on average benefits and average costs. However, heterogeneous treatment effects and/or costs are most often present, which means that there is an efficiency potential hidden in the implementation of public programs, if policies can be targeted at those who, net of costs, benefit the most. We introduce efficiency potential defined as the ratio between the net benefit achieved under perfect selection of the individuals with significant positive net benefit of program participation, and the actually realized benefits net of costs. Using data from a randomized control-trial experiment of a Danish return-to-work program combined with rich administrative records and survey data, we find that there is indeed a potential for increased efficiency. Results from the treatment literature indicate that, generally, it may be difficult to harvest the full potential. Our application corroborates this finding.
