Measuring Consumer Willingness to Pay for a Health Risk Reduction of Salmonellosis and Campylobacteriosis

This paper presents an application of the contingent valuation method (CVM) and choice experiments (CEs). We examine consumer willingness to pay (WTP) for different health risk reduction levels of Salmonellosis and Campylobacteriosis acquired from the consumption of chicken breast. We test for the embedding effect. The embedding effect was not found in the CVM format. It was however present in the CEs. The WTP values in the CVM format rages from Euro 1.29 to 3.34, whereas the WTP obtained by the CEs ranges from Euro -0.16 to Euro 6.68 depending on the disease and the corresponding risk reduction levels.chicken, choice experiments, contingent valuation method, food safety, willingness to pay, Food Consumption/Nutrition/Food Safety, C9, D8, D12,

The economic value of food labels: A lab experiment on safer infant milk formula

Enterobacter sakazakii, a pathogen that can be found in powdered infant milk formula, can cause adverse health effects on infants. Using Vickrey auction, this study examines parents' willingness to pay (WTP) for a quality assurance label on powdered infant milk formula. The influence of ambiguity with the incidence rate information and provision of safe-handling information on WTP are also evaluated using three experiments/treatments. The mean price premium parents are willing to pay for the safer and quality assurance labelled powdered infant milk formula ranges from 61 to 133 Eurocents per 100 grams depending on the treatment. While no ambiguity effects are generally found, provision of safe-handling information has a significant influence on WTP. When the safe-handling information was given, WTP for the quality assurance label was significantly reduced and ranged from 39 to 69 Eurocents per 100 grams depending on the treatment. The results suggest that parents significantly value a quality assurance label with or without clear incidence rate information. Parents' valuation of the label, however, is reduced with the provision of safe-handling information.Ambiguity, Food Safety, Health Risk Information, Lab Experiment, Powdered Infant Milk Formula, Food Consumption/Nutrition/Food Safety,

Addressing climate change with behavioral science:A global intervention tournament in 63 countries

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.</p
