Abstract Recent labeling policies in developed countries place new focus on origin labeling, especially country of for a variety food products. It is not clear if this emphasis the result more ethnocentric consumer preferences food. We measure four different international locations and one domestic control location using conjoint experiment to test null hypotheses that consumers do have stronger own‐country preferences. In addition, we compare relative importance their genetically modified...

A concern with the contingent valuation method (CVM) is finding that hypothetical and real statements of value often differ. We test whether bias, broadly defined, independent location by comparing votes on a dichotomous choice referendum in China, France, Indiana, Kansas, Niger. find significant differences bias across locations reject hypothesis location. As opposed to typical reported literature, subjects Niger significantly understated their willingness-to-pay referendum. <i>(JEL Q51)</i>

We accomplish these aims through a comprehensive review of by scientists, economists, other social legal experts, government groups international trade organisations. Existing is heavily weighted towards science, packaging labelling, areas knowledge discovery. Moving forward, needed pertaining general economic...

Fraudulent activities in the international honey market affect 10% of food, and cost global food $50 billion per annum. Although many developed countries have created regulations to combat fraud, illegally imported honey, especially originating from China, still enters through transshipments relabelling mask its true origin. This laundering poses a health risk consumers, as Chinese potentially contains illegal unsafe antibiotics high levels herbicides pesticides. We analyse whether...

The coronavirus disease 2019 (COVID-19) pandemic's first wave led to declining mental health and life satisfaction outcomes for college students, especially women. While women in undergraduate agricultural programs outperformed men academically prior during the pandemic, achievement may have come at personal cost, those with fewer environmental resiliency resources. Our research objective was expand on personal, social, factors linked lower scores students agriculture pandemic. We measured...

Abstract We examine the causes and policy implications of strategic (willful) ignorance risk as an excuse to over-engage in risky health behavior. In experiment on Copenhagen adults, we allow subjects choose whether learn calorie content a meal before consuming it then measure their subsequent intake. Consistent with previous studies, find strong evidence ignorance: 46% ignore information, these subsequently consume more calories average than they would have had been informed. While studies...

ABSTRACT Many poor countries remain trapped in a cycle of poverty and environmental degradation. Understanding how people react to existing proposed solutions most likely can be improved using the methods experimental economics. Experiments provide researchers method test theory, look for patterns behavior, testbed economic institutions incentives, educate people. Herein we explore economics has been used could help guide decision making increase prosperity without overexploiting resource...

Abstract Recent work with Randomized Controlled Trials (RCTs) in development economics has contributed to economists' use of the experimental mindset inform policy choices. Development scholars, however, question authority RCT evidence, and worry that trend will turn their profession away from theory econometrics. We examine this challenge, as well RCTs' role within broader area, a thorough review relevant literature. find generic fears are overstated. Experimental methods should be...

Laboratory market experiments are used to estimate the incidence of a stylized subsidy in factor negotiations with university student and agricultural professional subjects. In separate sessions both groups, prices converged approximately four half tokens higher when 20-token per-unit was paid buyers; this equates 44% predicted 10-token split. A proportional incentive treatment clarifies effect. Discrepancies between observed similar previous empirical estimates land rental markets....

We use laboratory market experiments to assess the impact of asymmetric knowledge a per-unit subsidy and effect decoupled annual income on factor outcomes. Results indicate that when is tied as subsidy, regardless full or for participants, subsidized buyers distribute nearly 22 percent sellers. When fully from factor, case with payment, payment incidence mitigated prices are not statistically different no-policy treatment.
