Framed field experiment on resource scarcity & extraction: path-dependent generosity within sequential water appropriation

Alexander Pfaff, Maria Alejandra Vélez, Pablo Andres Ramos, Adriana Molina Ecological Economics 120 (2015) 416–429 How one treats others is important within collective action. We ask if resource scarcity in the past, due to its effects upon past behaviors, influences current other-regarding behaviors. Contrasting theories and empirical findings on scarcity motivate our framed field experiment. […]

Evolution of households’ responses to th

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 […]

Unequal Information, Unequal Allocation: bargaining field experiments in NE Brazil

Alexander Pfaff, Maria Alejandra Velez, Renzo Taddei, Kenneth Broad Environmental Science & Policy 26 (2013) 90-101 We assess how unequal information affects the bargaining within resource allocation, a stakeholder interaction that is critical for climate adaptation within the water sector. Motivated by water allocation among unequal actors in NE Brazil, within Ceara´ State, we employ […]

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 […]

Efficiency and equity in negotiated resource transfers: contributions and limitations of trust with limited contracts

Alexander Pfaff, Maria Alejandra Velez Ecological Economics 74 (2012) 55–63 We consider a case of water reallocation in Brazil, one which has numerous analogs elsewhere. To permit empirical study of the effects of institutions that can facilitate or restrict  allocations, we conducted field experiments to explore trust’s potential when resource contracts are limited, using a […]

Behavior, Environment, and Health in Developing Countries: evaluation and valuation

Subhrendu Pattanayak, Alexander Pfaff Annual Review of Resource Economics (2009) 1:183–217 We consider health and environmental quality in developing countries, where limited resources constrain behaviors that combat enormously burdensome health challenges. We focus on four huge challenges that are preventable (i.e., are resolved in rich countries). We distinguish them as special cases in a general […]

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 […]

Responses of 6500 households to arsenic mitigation in Araihazar, Bangladesh

Alisa Opar, Alexander Pfaff, A.A. Seddique, Kazi Matin Ahmed, Joseph H. Graziano, Alexander van Geen Health & Place 13 (2007) 164–172 This study documents the response of 6500 rural households in a 25 km2 area of Bangladesh to interventions intended to reduce their exposure to arsenic contained in well water. The interventions included public education, […]

Climate, Stream Flow Prediction and Water Management in Northeast Brazil: societal trends and forecast value

Kenneth Broad, Alexander Pfaff, Renzo Taddei, Sankar Arumugam, Upmanu Lall, Francisco Assis de Souza Filho Climatic Change (2007) 84:217–239 We assess the potential benefits from innovative forecasts of the stream flows that replenish reservoirs in the semi-arid state of Ceará, Brazil. Such forecasts have many potential applications. In Ceará, they matter for both water-allocation and […]

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. […]

Effective & Equitable Dissemination of Seasonal-to-Interannual Climate Forecasts: policy implications from the Peruvian fishery during El Nino 1997-98

Kenneth Broad, Alexander Pfaff, Michael. H. Glantz Climatic Change 54: 415–438, 2002 The development of seasonal-to-interannual climate predictions has spurred widespread claims that the dissemination of such forecasts will yield benefits for society. Based on the use as well as non-use of forecasts in the Peruvian fishery during the 1997–98 El Niño event, we identify: […]

Generating Probabilities in Support of Societal Decision Making:  the case of abrupt climate change

Alexander Pfaff, Dorothy M. Peteet EOS (American Geophysical Union), May 15 2001 Earth-science predictions of natural phenomena are increasingly seen as valuable aids to improved societal decision making. Pielke et al. recently (EOS 7/13/99) argued persuasively that good predictions alone won’t achieve better societal decisions. These authors’ call to change the decision environments in which […]
