Effective interventions are needed to promote more sustainable and healthier food choices for both human and planetary health. This study will evaluate two interventions in two independent adaptive design randomised controlled trials (one 2-arm and one 3-arm trial) within the same study population (a factorial design is not powered). The interventions are (i) eco-labelling, which will provide participants with information on the environmental impact of their food purchases using a score ranging from A (most sustainable) to G (least sustainable); and (ii) price discounts on alternative products with a better sustainability profile (and equal or better nutritional profile) in place of specific products in their basket. To implement these interventions, we will use a browser extension on o...
In our previous experiment (Chen and Guan, 2021), we find a significant detrimental effect of auditory descriptions on economic rationality relative to visual descriptions. This disparity may stem from the tendency of individuals to process auditory information sequentially, as opposed to the simultaneous processing of visual information. In this follow-up experiment, we investigate this potential underlying mechanism by prompting subjects to process auditory and visual information sequentially in a tightly controlled setting. By comparing the economic rationality of the two new treatments, we aim to determine the driving mechanism affecting economic rationality when information is presented either visually or auditorily. If the experiment finds no significant differences between the Vi...
In this study, we examine the impact of the flipped classroom against standard class on learning outcomes of students of an introductory economics course offered in the Spring semester of 2022. The experiments of the flipped classroom is conducted in the two sections of the introductory economics course, where the students are randomly assigned to the two sections by the administration office of the economics department.
I study the effect of how players in a board game generate their rolls on subjects' beliefs of certain players' winning probabilities in a board game. In particular, it is varied whether players use a tablet computer vs. whether they use a physical die and a dice shuffler to generate their die rolls. The study is implemented as an RCT laboratory experiment. See also the attached pre-analysis plan.
In this paper, we provide experimental evidence on the effect of improving childcare quality on prices and profits of childcare providers, as well as the effects on families and children. Specifically, we partner with Kidogo, a social enterprise that provides training and mentorship to daycare providers. We randomize the entry of Kidogo into 30 low-income, urban communities of Kenya, leaving 30 communities as comparison. We then analyze the effect of their entry with detailed surveys of approximately 2000 providers. The main outcome measures are the price, quality, profits, and availability of childcare 6 months, and 12 months, and 24 months after entry. We pair that data with 2,100 surveys of families with small children in the same communities to examine the effect of improving childc...
This paper experimentally tests multiple multi-attribute choice models such as a range normalization model and a pairwise normalization model in a consumer context. The experimental design generates choice sets that can distinguish the models as each model predicts a distinct set of demand types. Specifically, we do comparative statics by investigating how choice probabilities of alternatives vary between choice sets. Moreover, we do a cross-validation exercise by constructing a maximum likelihood in the spirit of Harless and Camerer (1994).
Despite easily accessible information about the negative health externalities of environmental pollution, households' marginal willingness to pay for environmental quality is surprisingly low. In light of this puzzle, we design a large-scale online experiment to better understand individuals' attitudes towards air pollution-related information. We focus on two mechanisms: information avoidance and memory retention. In addition, we test whether an increase in perceived control over one's own health outcomes reduces failures to attend to information. To do so, participants in the experiment are asked whether they would like to acquire information about the number of life-years lost in their home region due to air pollution. Before participants make their decision, we exogenously increase ...
Modern social communication systems–ranging from email to social media systems–present a dizzying number of decisions for users. Privacy configurations, when not hidden by social media companies, are opaque. Individuals sometimes are also not aware of the externality that their sharing decisions can have to others. Thus, it is often hard for individuals to react or behave in ways that model the personal behaviors or are communally advantageous. Personalized recommendations, interfaces, interventions or nudges can help but implementing these requires an understanding end-user preferences. Our research seeks to tackle this challenge by modeling individual preferences through the use of economic games, both in a neutral context and in specific scenarios. Simultaneously, we will collect use...
Schools with better management practices are associated with higher student learning. But there is limited experimental evidence on the causal effect of improving school management practices on achievement, especially in developing countries. Existing efforts are often limited due to low adoption of the management practices by school leaders, potentially due to training programs that lack follow-up and a structure of accountability. We will conduct a randomized evaluation of a large-scale school leadership training program in India. We will randomly assign nearly 400 public schools in Telangana, India to 1) a control group (C), 2) leadership workshops (T1), 3) workshops plus individualized coaching (T2). We will evaluate the impact and cost-effectiveness of each treatment on school lead...
Our study explores the impact of a supervisor’s racial identity on how hiring managers utilize new information about racial groups to revise their beliefs regarding worker productivity. This proposed intervention is grounded in literature indicating that the identity of supervisors can influence employees’ behavior and alter their perception of their supervisor’s priorities (Jeanquart-Barone 1996; Roberts 2005; Bradley et al. 2018). Additionally, we examine whether sharing a supervisor’s racial identity shifts how hiring managers express their racial attitudes. To determine whether non-Bayesian updating among hiring managers depends on the supervisor’s racial identity, we will conduct an experiment using the Prolific survey platform. In this experiment, we will randomly present a photo ...
