Government programs promoting locally produced foods have risen dramatically. But are these programs actually convincing consumers to pay more for locally produced food? Studies to date, which have mostly relied on hypothetical stated preference surveys, suggest that consumers will pay premiums for various local foods and that the premiums vary with the product and presence of any geographic identity. This study reports results from a large field experiment involving 1,050 adult consumers to reveal consumers’ willingness to pay (WTP) premiums for “locally produced” foods – mushrooms and oysters. Despite strong statistical power, this study reveals no positive effect of the locally produced label on consumer WTP. These null results are contrary to most of the existing literature on this topic. The finding that consumers are not willing to pay more for local foods has important implications for state and federal agencies that promote labeling campaigns that seek to increase demand and generate premiums for locally produced foods.

U.S. soybean farmers are currently grappling with dicamba herbicide drift. Using a network diffusion framework that accommodates key features of soybean farmer networks, we estimate the damages incurred from dicamba drift across different regions. Under our baseline assumptions, we estimate an average yield loss of 3% and predict sizable levels of forced switching to dicamba-resistant seed in response to drift. The relative importance of drift on damage and seed choice holds across a range of economic and network assumptions. In the absence of policy, this damage may cause regional adoption rates of dicamba-resistant soybean seed to increase.

This paper studies whether school-based financial education has spillover effects from children to parents. Leveraging data from a large-scale experiment with public high schools in Peru and credit bureau records on the parents of the youth targeted, this study measures the impact of providing personal finance lessons during secondary school on parental financial behavior. Financial education lessons in the school yield limited average spillover effects, but lead to sizable effects on parental financial behavior within disadvantaged households. Among parents from poorer households, the treatment reduces default probability by 26%, increases credit scores by 5%, and increases current debt levels by 40%. The treatment has stronger effects among the parents of daughters, who experience a significant 6.7% increase in their credit score and a 28% reduction in their loan portfolio in arrears. Among the parents of boys, most of the spillover effects are muted.

Higher education enrolment and graduation rates have increased rapidly inter-generationally across much of the world, offering employers the promise of more knowledgeable recruits and promising individuals new means of social advancement. In the case of Bolivia, the labour force is becoming more heterogeneous over time, which could imply positive effects induced by a closer match between labour supply and recruiters’ needs. However, we show that this is not the case. We revisit the transition mechanisms from college to the workplace, positing recruiters’ interpretations of educational credentials as a crucial determining factor for employability in the formal sector. In a two-branch correspondence study, 2848 fictitious CVs were sent to 1424 formal firms in the three main urban Bolivian areas. We find a large university reputation premium. Applicants from well-valued universities are around 40% more likely to receive a positive response – a 2.25 percentage point advantage from a 7.87% baseline likelihood. Thus, the increasingly heterogeneous labour force is generating additional informational frictions in the labour market, rather than promoting a more efficient matching process.

Most decisions involving risk are not taken in isolation. In addition to the risk from that decision, other independent, so-called ‘background’ risks, are considered. Our research adds to the growing evidence that this background risk influences risk-taking. We report results from a repeated lab-in-the-field investment task with Senegalese fishers in the presence of background risk related to their fishing income and their health. Our measure of background risk is the monthly wind condition. Without controls, we find that fishers act on average intemperately. Adding controls, we find that the impact of background risk on risk-taking—measured as the investment in the investment task—depends on the boat size of the fishers. When dividing the sample according to wealth, we find temperate behavior for the relatively poorer group and intemperate behavior that depends on boat lengths for the relatively richer group. Our results show the interrelations between background risk and context factors.

We assess the effects of the Crianza Positiva text and audio e-messaging program on caregiver–child language interaction patterns. The program is a six-month-long intervention for families with children aged 0–2 aimed at strengthening parental competences. Its design exploits behavioral tools such as reminders, suggestions of action, and messages of encouragement to reinforce and sustain positive parenting practices. Families in 24 early childhood centers in Uruguay that completed an eight-week workshop were randomized into receiving or not receiving mobile messages. After the program, we videotaped 10-minute sessions of free play between the caregiver and the child, and decoded language patterns using automated techniques. The intervention was successful at improving the quality of parental vocalizations, as measured by the parent's pitch range. We also found suggestive evidence of increases in the duration of adult vocalizations. The results are consistent with more frequent parental self-reported involvement in reading, telling stories, and describing things to the child. Regarding the child, we find a nonrobust decrease in the duration of vocalizations, which we attribute to a crowding-out effect by the caregiver in the context of a fixed 10-minute suggested activity and a more proactive parental role.

Economic experiments have been widely used to elicit individuals' evaluation for various commodities. Common elicitation methods include auction and posted price mechanisms. A field experiment is designed to compare willingness-to-pay (WTP) estimates between these two mechanisms. Despite both of these formats being theoretically incentive compatible and demand revealing, results from 115 adult consumers indicate that WTP estimates obtained from an auction are 32–39 percent smaller than those from a posted price mechanism. A comparison in statistical significance shows that auctions require a smaller sample size than posted price mechanisms in order to detect the same preference change. Nevertheless, the signs of marginal effects for different product characteristics are consistent in both mechanisms.

Bystander programs contribute to crime prevention by motivating people to intervene in violent situations. Social media allow addressing very specific target groups, and provide valuable information for program evaluation. This paper provides a conceptual framework for conducting benefit–cost analysis of bystander programs and puts a particular focus on the use of social media for program dissemination and data collection. The benefit–cost model treats publicly funded programs as investment projects and calculates the benefit–cost ratio. Program benefit arises from the damages avoided by preventing violent crime. We provide systematic instructions for estimating this benefit. The explained estimation techniques draw on social media data, machine-learning technology, randomized controlled trials and discrete choice experiments. In addition, we introduce a complementary approach with benefits calculated from the public attention generated by the program. To estimate the value of public attention, the approach uses the bid landscaping method, which originates from display advertising. The presented approaches offer the tools to implement a benefit–costs analysis in practice. The growing importance of social media for the dissemination of policy programs requires new evaluation methods. By providing two such methods, this paper contributes to evidence-based decision-making in a growing policy area.

This paper used a randomised field experiment to test if tailoring an email invitation induces pension scheme participants to delve into their online personal pension situation. Action perspective and degree of urgency conveyed in the invitation were tailored based on gender and age. Overall, our empirical findings show that such tailoring had no positive effects on (1) the probability that pension scheme participants click on the weblink to access information about their pension situation and (2) the probability to log in to a tool for pension check.

To further improve the understanding of promoting locally grown lavender, we examine consumer willingness to pay (WTP) for three lavender-based products: lavender bundles, culinary lavender, and lavender oil. We evaluate an online sample located in the southeast using a double-bounded dichotomous choice contingent valuation survey. Lavender bundles have the highest WTP, followed by oil and culinary lavender. Certain marketing factors result in higher WTP, including product familiarity, familiarity with the Georgia Grown program, and shopping frequency at farmers’ markets. This study provides a better understanding of the opportunity for small-scale farmers to market specialty crops such as lavender.

To ensure the long-term sustainability of the US Social Security System, several policy alternatives can theoretically be implemented. However, in practice, consumer responses can be challenging for policymakers to anticipate. We conducted a randomized survey on the nationally-representative Understanding America Study (UAS) panel where respondents were presented with a series of ‘policy scenarios’ in which the government enacts alternative reforms aimed to reduce the expected shortfall in the trust fund that pays Social Security retirement benefits. These scenarios included an increase in the Social Security payroll tax, an increase in the wage ceiling, and a reduction of benefits. We find that changes in respondents’ subjective expectations about their benefits and how this will affect their behaviors are directionally consistent with what would be expected when individuals are attentive to the available information and form rational expectations (e.g., monthly benefit expectations increase upon the announcement of an increase in the Social Security tax rate or in the wage ceiling, and they decrease less-than-proportionally with hypothetical benefit cuts). However, surprisingly, these changes are not sensitive to the magnitudes of policy change (e.g., the increase in expected benefits is about the same regardless of the size of Social Security payroll tax increases). Individuals with higher levels of education, cognitive ability, and financial literacy are more likely to adjust their expectations as predicted by theory.

Married men's Social Security claiming behavior does not always take into account spouse and survivor benefits. Specifically, married men tend to choose claiming ages that do not maximize the household's and widow's expected present value of benefits. To understand what contributes to this pattern, we conduct an online survey experiment with a representative sample of Americans. We randomly assign respondents to one of four vignettes that present information about a character who is choosing when to claim his retirement benefits. The vignettes differ by whether the character is married or not, whether information about survivor benefits is presented, and whether the information includes an illustrative example. We next ask respondents to provide advice to the character about when to claim. We find that (1) respondents do value survivor benefits for spouses, and (2) information about survivor benefits tends to increase the suggested claiming ages only among the subgroup of respondents who are the least knowledgeable about these benefits.

This paper presents results from an online experiment that tested the effect of simple, concise information on respondents' knowledge of the rules of Social Security's Retirement Earnings Test (RET). We find that a straightforward, simple information treatment has a large effect on knowledge of the RET and on prospective choices regarding working and claiming benefits. We tested two additional information treatments that provided more comprehensive information and used illustrative examples. One of the additional treatments used only text, while the other one included a visual tool. Our results suggest that the additional treatments did not further improve knowledge; the simplest intervention yielded the same effect as the more comprehensive ones.

The roots and uses of economic experiments in problem solving and hypothesis testing are explored in the present article. The literature suggests that the primary advantage of economics experiments is the ability to use controlled stimuli to test economic hypotheses. Other literature also suggests that experiments are useful in problem solving settings. The advantages and disadvantages of experiments are discussed.

Information about cigarettes can help smokers come to an informed decisionabout what cigarettes to purchase. Countermarketing information can helpsmokers make informed decisions, but little is known about the value of thisinformation to smokers. In this article, we use data from experimentalauctions to estimate the value of countermarketing information that countersindustry claims about reduced-risk cigarettes. We find that this informationhas significant value to smokers who have been exposed to marketinginformation from tobacco companies touting reduced-risk cigarettes, but wefind no evidence it provides value to smokers not exposed to this marketinginformation.

The current fiscal climate is focusing attention on the need for more efficient government. However, we have remarkably little rigorous information on which are the most cost-effective strategies for achieving common goals like delivering high quality education in deprived neighbourhoods or reducing carbon emissions. This paper argues that randomised impact evaluations can provide an effective way to generate the information needed to make government more effective. Advances in the theory and practice of running randomised evaluations mean that a wider range of questions can be answered than ever before. Elsewhere in the world, fundamental questions are being answered about how humans behave, which in turn are being used to design new policies which themselves are rigorously tested. By learning from these results, and by conducting more randomised evaluations on issues important to UK policy (both at home and abroad) it will be possible to design more effective policies and do more with less.
