    Fiscal Policy Instruments for Reducing Congestion and Atmospheric Emissions in the Transport Sector : A Review
    (World Bank, Washington, DC, 2008-06) Timilsina, Govinda R. ; Dulal, Hari B.
    This paper reviews the literature on the fiscal policy instruments commonly used to reduce transport sector externalities. The findings show that congestion charges would reduce vehicle traffic by 9 to 12 percent and significantly improve environmental quality. The vehicle tax literature suggests that every 1 percent increase in vehicle taxes would reduce vehicle miles by 0.22 to 0.45 percent and CO2 emissions by 0.19 percent. The fuel tax is the most common fiscal policy instrument; however its primary objective is to raise government revenues rather than to reduce emissions and traffic congestion. Although subsidizing public transportation is a common practice, reducing emissions has not been the primary objective of such subsidies. Nevertheless, it is shown that transport sector emissions would be higher in the absence of both public transportation subsidies and fuel taxation. Subsidies are also the main policy tool for the promotion of clean fuels and vehicles. Although some studies are very critical of biofuel subsidies, the literature is mostly supportive of clean vehicle subsidies.

    A Review of Regulatory Instruments to Control Environmental Externalities from the Transport Sector
    ( 2009-03-01) Timilsina, Govinda R. ; Dulal, Hari B.
    This study reviews regulatory instruments designed to reduce environmental externalities from the transport sector. The study finds that the main regulatory instruments used in practice are fuel economy standards, vehicle emission standards, and fuel quality standards. Although industrialized countries have introduced all three standards with strong enforcement mechanisms, most developing countries have yet to introduce fuel economy standards. The emission standards introduced by many developing countries to control local air pollutants follow either the European Union or United States standards. Fuel quality standards, particularly for gasoline and diesel, have been introduced in many countries mandating 2 to 10 percent blending of biofuels, 10 to 50 times reduction of sulfur from 1996 levels, and banning lead contents. Although inspection and maintenance programs are in place in both industrialized and developing countries to enforce regulatory standards, these programs have faced several challenges in developing countries due to a lack of resources. The study also highlights several factors affecting the selection of regulatory instruments, such as countries' environmental priorities and institutional capacities.

    A Preliminary Study of Intimate Partner Violence Among Nepali Women in the United States
    ( 2009) Thapa-Oli, S. ; Dulal, H. B. ; Baba, Y.
    Although there is a growing number of studies on intimate partner violence ( IPV) in U. S. South Asian communities, the examination of IPV among Nepali women in the United States is still in the initial stage. The purpose of this study was to assess the prevalence of and vulnerabilities to IPV among 45 Nepali immigrant women residing in the New York metropolitan area. The findings demonstrated that 75.6% of women had been verbally insulted by their current partners, and 62.2% had to seek permission from their partners to go to their friends' or relatives' houses.

    Regulatory Instruments to Control Environmental Externalities from the Transport Sector
    ( 2009) Timilsina, Govinda R. ; Dulal, Hari B.
    This study reviews regulatory instruments designed to reduce environmental externalities from the transport sector. We find that the main regulatory instruments used in practice are fuel economy standards, vehicle emission standards, and fuel quality standards. While industrialized countries have introduced all three standards with strong enforcement mechanisms, most developing countries have yet to introduce fuel economy standards. The emission standards introduced by many developing countries to control local air pollutants follow either the EU or U.S. standards. Fuel quality standards, particularly for gasoline and diesel, have been introduced in many countries mandating 2 to 10 percents blending of biofuels, 10 to 50 times reduction of sulfur from 1996 levels and banning lead contents. Although inspection and maintenance (I/M) programs are in place in both industrialized and developing countries to enforce regulatory standards, these programs have faced several challenges in developing countries due to a lack of resources. The study also highlights several factors affecting the selection of regulatory instruments, such as countries' environmental priorities and institutional capacities.
