Última Tying Odysseus to the Mast: Evidence from a Commitment Savings Product in the Philippines AgEcon Ashraf, Nava; Karlan, Dean S.; Yin, Wesley. We designed a commitment savings product for a Philippine bank and implemented it using a randomized control methodology. The savings product was intended for individuals who want to commit now to restrict access to their savings, and who were sophisticated enough to engage in such a mechanism. We conducted a baseline survey on 1777 existing or former clients of a bank. One month later, we offered the commitment product to a randomly chosen subset of 710 clients; 202 (28.4 percent) accepted the offer and opened the account. In the baseline survey, we asked hypothetical time discounting questions. Women who exhibited a lower discount rate for future relative to current tradeoffs, and hence potentially have a preference for commitment, were indeed...

Ano: 2005 URL: http://purl.umn.edu/28411 Deposit Collectors AgEcon Ashraf, Nava; Karlan, Dean S.; Yin, Wesley. Informal lending and savings institutions exist around the world, and often include regular door-to-door deposit collection of cash. Some banks have adopted similar services in order to expand access to banking services in areas that lack physical branches. Using a randomized control trial, we investigate determinants of participation in a deposit collection service and evaluate the impact of offering the service for micro-savers of a rural bank in the Philippines. Of 137 individuals offered the service in the treatment group, 38 agreed to sign-up, and 20 regularly used the service. Take-up is predicted by distance to the bank (a measure of transaction costs of depositing without the service) as well as being married (a suggestion that household bargaining...

Ano: 2005 URL: http://purl.umn.edu/28502 Expected Utility or Prospect Theory Maximizers? Results from a Structural Model based on Field-experiment Data AgEcon Bocqueho, Geraldine; Jacquet, Florence; Reynaud, Arnaud. We elicit risk preferences of French farmers in a field experimental setting under expected utility theory and cumulative prospect theory. We use two different estimation methods, namely the interval approach and the estimation of a random preference model. On average, farmers are risk averse and loss averse. They also exhibit an inverse S-shaped probability weighting function, meaning that they tend to overweight small probabilities and underweight high probabilities. We infer from our results that CPT explains farmers’ behaviour better than EUT in the context of our experiment. We also investigate how preferences correlate with individual socio-demographic characteristics. We find that education and agricultural innovation are negatively linked with risk...

Ano: 2011 URL: http://purl.umn.edu/114257 Right-to-Choose Auctions: A Field Study of Water Markets in the Limari Valley of Chile AgEcon Alevy, Jonathan E.; Cristi, Oscar; Melo, Oscar. Field experiments were conducted with farmers in the Limarí Valley of Chile to test extant theory on right-to-choose auctions. Water volumes that differed by reservoir source and time of availability were offered for sale by the research team. The auctions were supplemented by protocols to elicit risk and time preferences of bidders. We find that the right-to-choose auctions raise significantly more revenue than the benchmark sequential auction. Risk attitudes explain a substantial amount of the difference in bidding between auction institutions, consonant with received theory. The auction bidding revealed distinct preferences for water types, which has implications for market re-design.

Ano: 2010 URL: http://purl.umn.edu/90821 What's Psychology Worth? A Field Experiment in the Consumer Credit Market AgEcon Bertrand, Marianne; Karlan, Dean S.; Mullainathan, Sendhil; Shafir, Eldar; Zinman, Jonathan. Numerous laboratory studies report on behaviors inconsistent with rational economic models. How much do these inconsistencies matter in natural settings, when consumers make large, real decisions and have the opportunity to learn from experiences? We report on a field experiment designed to address this question. Incumbent clients of a lender in South Africa were sent letters offering them large, short-term loans at randomly chosen interest rates. Psychological “features” on the letter, which did not affect offer terms or economic content, were also independently randomized. Consistent with standard economics, the interest rate significantly affected loan take-up. Inconsistent with standard economics, the psychological features also significantly affected...

Ano: 2005 URL: http://purl.umn.edu/28441 THE WTP/WTA DISPARITY: HAVE WE BEEN OBSERVING DYNAMIC VALUES BUT INTERPRETING THEM AS STATIC? AgEcon Kling, Catherine L.; List, John A.; Zhao, Jinhua. This study advances, and experimentally tests, a new explanation for the disparity between willingness to pay (WTP) and willingness to accept (WTA)-a dynamic neoclassical theory based on the presence of commitment costs. While to date neoclassical models have not explained the observed data patterns well, we find that the commitment cost theory is able to explain adequately the causes and severity of the WTP/WTA value disparity. In particular, using data gathered from an actual marketplace, even the most stringent of our theoretical conjectures-cases where WTP values are predicted to exceed WTA values-oftentimes are met.

Ano: 2003 URL: http://purl.umn.edu/18595 Revisiting Cheap Talk with New Evidence from a Field Experiment AgEcon Silva, Andres; Nayga, Rodolfo M., Jr.; Campbell, Benjamin L.; Park, John L.. We assess the reduction of hypothetical bias in consumers’ willingness to pay (WTP) for products by applying a generic, short, and neutral cheap talk script in a retail setting. Using an open-ended elicitation mechanism with non-hypothetical, hypothetical, and hypothetical with cheap talk treatments, our results indicate that the hypothetical WTP values are higher than the nonhypothetical values, but the hypothetical with cheap talk values are not significantly different from non-hypothetical estimates.

Ano: 2006 URL: http://purl.umn.edu/18454 Consumer Willingness to Pay for "Second-Generation" Genetically Engineered Products and the Role of Marketing Information AgEcon Rousu, Matthew C.; Monchuk, Daniel C.; Shogren, Jason F.; Kosa, Katherine M.. Environmental and consumer groups have called for mandatory labeling of genetically engineered (GE) food products in the United States, stating that consumers have the “right to know.” Herein, we use a nonhypothetical field experiment to examine the willingness to pay for GE-labeled products, using the only second-generation GE product currently on the U.S. market-GE cigarettes. Our results suggest consumers pay less for GE-labeled cigarettes when marketing information is absent. But, when presented with marketing information on the attributes of the cigarette, we find no evidence that consumers pay less for GE-labeled cigarettes.

Ano: 2005 URL: http://purl.umn.edu/43501 Farmers as Producers of Clean Water: Getting Incentive Payments Right and Encouraging Farmer Participation AgEcon Collins, Alan R.; Maille, Peter. This research involved a field experiment using watershed payments as an incentive for farmers to address agricultural non-point pollution (ANP). Objectives were to: (1) describe how payments were estimated for a field experiment; (2) explain why a team approach is needed for ANP; (3) discuss the essential elements used for recruitment of farmers into a field experiment setting; and (4) address whether or not farmers were motivated to participate and pursue ANP abatement. One year into the experiment, the results are encouraging. About one-half of farmers who attended meetings are participating. They own or operate approximately 41% of the agricultural land in the watershed. Farmer actions to date have included determining an allocation formula for...

Ano: 2008 URL: http://purl.umn.edu/6342 External Validity of Hypothetical Surveys and Laboratory Experiments AgEcon Chang, Jae Bong; Lusk, Jayson L.; Norwood, F. Bailey. We compare the ability of three preference elicitation methods (hypothetical choices, non-hypothetical choices, and non-hypothetical rankings) and three discrete-choice econometric models (the multinomial logit, the independent availability logit, and the random parameter logit) to predict actual retail shopping behavior in three different product categories (ground beef, wheat flour, and dishwashing liquid). Overall, across all methods, we find a reasonably high level of external validity. Our results suggest that the non-hypothetical elicitation approaches, especially the non-hypothetical ranking, outperformed the hypothetical choice experiment in predicting retail sales. We also find that the random parameter logit can have superior predictive...

Ano: 2008 URL: http://purl.umn.edu/43600 Observing Unobservables: Identifying Information Asymmetries with a Consumer Credit Field Experiment AgEcon Karlan, Dean S.; Zinman, Jonathan. Information asymmetries are important in theory but difficult to identify in practice. We estimate the empirical importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South African lender along three dimensions: 1) the initial "offer interest rate" appearing on direct mail solicitations; 2) a "contract interest rate" equal to or less than the offer interest rate and revealed to the over 4,000 borrowers who agreed to the initial offer rate; and 3) a dynamic repayment incentive that extends preferential pricing on future loans to borrowers who remain in good standing. These three randomizations, combined with complete knowledge of the...
