Última Incorporating local institutions in irrigation experiments: evidence from rural communities in Pakistan Ecology and Society Javaid, Aneeque; Leibniz Center for Tropical Marine Ecology (ZMT); Jacobs University; aneeque.javaid@zmt-bremen.de; Falk, Thomas; University of Marburg; falkt@staff.uni-marburg.de. Many irrigation systems are special cases of common-pool resources (CPRs) in which some users have preferential access to the resource, which in theory aggravates collective action challenges such as the under-provision of necessary infrastructure as a result of unequal appropriation of water resources. We present experimental evidence based on an irrigation game played in communities that are dependent on one of the largest contiguous irrigation network: the Indus basin irrigation system in Punjab, Pakistan. Furthermore, we simulate two institutional mechanisms that are neglected in experimental studies, despite their importance in many CPR governance systems: traditional authorities and legal pluralism. In our experiments, Punjabi farmers (N = 160)...

Ano: 2015 Management of climate risks in the wine sector: a field study on risky behaviour AgEcon Ben Salk, Sana; Blondel, Serge; Daniel, Christophe; Deffains-Crapsky, Catherine; Jutard, Catherine; Sejourne, Bruno. In agriculture, there is need for a deeper analysis of management of climate risks, because the farmers appear to have a paradoxical position: they perceived that they are strongly exposed to climate risks but, they do not want to pay for adapted tools, arguing that this is too expensive or complex. However, under risk, it is well-known that the decision-makers could be subject to paradox (Allais for example). Our assumption is that to know better the behaviours of farmers in general risky situations will help to understand their reluctance to use the weather market. We conducted a study over the wine growers in the Maine-et-Loire department. 60 wine growers have responded to the questionnaire about climate risk management, and 29 amongst them have...

The valuation of traceable or safety-branded food by consumers in developing countries affected by diseases such as avian influenza, or with food safety issues in general, is very difficult to identify. Products that have safety-branding are not common, and food is usually purchased by bargaining at informal markets. However, valuation of traceability has important implications for livestock disease policies as well as agricultural sector development. Through developing a short-term certified supply chain for free range chicken in Hanoi, we were able to conduct a combined field experiment and detailed household survey to measure the valuation of this type of poultry. We find that consumers in urban Hanoi on average have a welfare gain of about $1 per whole...

Ano: 2009 URL: http://purl.umn.edu/49444 Comparing the Effectiveness of Regulation and Pro-Social Emotions to Enhance Cooperation: Experimental Evidence from Fishing Communities in Colombia AgEcon Lopez, Maria Claudia; Murphy, James J.; Spraggon, John M.; Stranlund, John K.. This paper presents the results from a series of framed field experiments conducted in fishing communities off the Caribbean coast of Colombia. The goal is to investigate the relative effectiveness of exogenous regulatory pressure and pro-social emotions in promoting cooperative behavior in a public goods context. The random public revelation of an individual’s contribution and its consequences for the rest of the group leads to significantly higher public good contributions and social welfare than regulatory pressure, even under regulations that are designed to motivate fully efficient contributions.

Recent evidence suggests that participants' misunderstanding of experimental auction mechanism can systematically bias auction results. We present a simple technique for testing whether field auction mechanism and, by extension, whether auction bids provide an unbiased estimate of participants' willingness to pay.

Evidence from a Field Experiment in Uganda AgEcon Chowdhury, Shyamal K.; Meenakshi, J.V.; Tomlins, Keith; Owori, Constance. Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in pro vitamins A and adapted to local growing environment have the potential to reduce the prevalence of vitamin A deficiency. One such example is the orange-fleshed sweetpotato. However because of its distinctive orange color, which is in contrast to the white varieties that are typically consumed in Africa, it is important to assess whether consumers will accept it. It is this question that this paper attempts to address, using a choice experiment with the real product to quantify the magnitude of the premium or discount in consumers’ willingness to pay that may be associated with it. In addition, it also considers...

Evidence from Field Experiments in Colombia AgEcon Lopez, Maria Claudia; Murphy, James J.; Spraggon, John M.; Stranlund, John K.. In this paper we describe a field experiment conducted among mollusk harvesters in a community on the Pacific Coast of Columbia. The experiment is based on a standard linear public good and consists of two stages. In the first stage we compare the ability of monetary and nonmonetary sanctions among community members to increase contributions to the public good. In the second stage we add a government regulation with either a high or low sanction for noncompliance to community enforcement efforts. The results for the first stage are consistent with other comparisons of monetary and nonmonetary sanctions within groups; both led to higher contributions. The results from the second stage reveal that government regulations always complemented community...

Ano: 2008 URL: http://purl.umn.edu/42128 Choosing a Cigarette Brand: Determining the Value of Countermarketing Information to Smokers Using Field Auctions AgEcon Rousu, Matthew C.; Nonnemaker, James; Farrelly, Matthew. Information about cigarettes can help smokers come to an informed decision about what cigarettes to purchase. Countermarketing information can help smokers make informed decisions, but little is known about the value of this information to smokers. In this article, we use data from experimental auctions to estimate the value of countermarketing information that counters industry claims about reduced-risk cigarettes. We find that this information has significant value to smokers who have been exposed to marketing information from tobacco companies touting reduced-risk cigarettes, but we find no evidence it provides value to smokers not exposed to this marketing information.
