Air pollution is one of the most pressing environmental challenges in rapidly developing countries, with severe consequences for public health. My research in this area focuses on public support for air pollution control policies in major Asian cities, including Beijing and New Delhi. This work examines how citizens evaluate different policy instruments — such as command-and-control regulations versus market-based instruments — and how features of the policy process, including exemptions, institutional conflict between branches of government, and elite polarization, shape both public support for pollution control and beliefs about the causes of pollution itself.
