Evolution of households’ responses to the groundwater arsenic crisis in Bangladesh:  information on environmental health risks can have increasing behavioral impact over time

Soumya Balasubramanya, Alexander Pfaff, Lori Bennear, Alessandro Tarozzi, Kazi Matin Ahmed, Amy Schoenfeld, Alexander van Geen Environment and Development Economics 19: 631–647 A national campaign of well testing through 2003 enabled households in rural Bangladesh to switch, at least for drinking water, from high-arsenic wells to neighboring lower arsenic wells. We study the well-switching dynamics […]

Impact of a randomized controlled trial in arsenic risk communication on household water-source choices in Bangladesh

Lori Bennear, Alessandro Tarozzi, Alexander Pfaff, Soumya Balasubramanya, Kazi Matin Ahmed, Alexander van Geen Journal of Environmental Economics and Management 65 (2013) 225–240 We conducted a randomized controlled trial in rural Bangladesh to examine how household drinking-water choices were affected by two different messages about risk from naturally occurring groundwater arsenic. Households in both randomized […]

Can Environmental Insurance Succeed Where Other Strategies Fail? The case of underground storage tanks.

Haitao Yin, Alexander Pfaff, Howard Kunreuther Risk Analysis 2011 volume 31 number 1: 12-24 (doi 10.1111/j.1539-6924.2010.01479.x) Private risk reduction will be socially efficient only when firms are liable for all the damage that they cause. We find that environmental insurance can achieve social efficiency even when two traditional policy instruments—ex post fines and risk management […]

Can information alone change behavior? Response to arsenic contamination of groundwater in Bangladesh

Malgosia Madajewicz, Alexander Pfaff, Alexander van Geen, Joseph Graziano, Iftikhar Hussein, Hasina Momotaj, Roksana Sylvia, Habibul Ahsan Journal of Development Economics 84 (2007) 731–754 We study how effectively information induces Bangladeshi households to avoid a health risk. The response to information is large and rapid; knowing that the household’s well water has an unsafe concentration […]

Stute, A. van Geen Science volume 314 (December 15, 2006): 1687-1688 Excessive levels of arsenic in drinking water is a vast health problem in Southeast Asia. Several viable approaches to mitigation could drastically reduce arsenic exposure, but they […]

UNICEF K.A.P. Survey Data Report

Malgosia Madajewicz, Alexander Pfaff UNICEF Report (with Jan Willem Rosenboom, unofficial earlier draft attached here) UNICEF Bangladesh, with assistance from a number of non-governmental agencies (NGOs), conducted surveys to assess the impact of arsenic contamination in Bangladesh. The surveys aimed to measure the knowledge levels, attitudes and behavioral patterns of respondents living in arsenic-affected areas. […]

To Err on Humans is not Benign: incentives for adoption of medical error-reporting systems

Joshua Graff Zivin, Alexander Pfaff Journal of Health Economics 23 (2004) 935–949 Concerns about frequent and harmful medical errors have led policy makers to advocate the creation of a system for medical error reporting. Health providers, fearing that reported information about errors would be used against them under the current medical malpractice system, have been […]

Big Field, Small Potatoes: an empirical assessment of EPA’s Self-Audit Policy

Alexander Pfaff, Chris William Sanchirico Journal of Policy Analysis and Management (2004) volume 23 number 3: 415–432 Environmental self-auditing is said to deserve and require encouragement. Although firms can audit themselves more cheaply and effectively than regulators, they are deterred for fear that information they uncover will be used against them. To reduce this disincentive, […]

Environmental Self-Auditing: setting the proper incentives for discovery and correction of environmental harm

Alexander Pfaff, Chris William Sanchirico Journal of Law, Economics & Organization (2000) volume 16 number 1: 189-208. Many firms conduct “environmental audits” to test compliance with a complex array of environmental regulations. Commentators suggest, however, that self-auditing is not as common as it should be, because firms fear that what they find will be used […]
