AEA RCT Registry currently lists 4732 studies with locations in 159 countries.
This study uses a survey-based experiment to test how the provision of descriptive social norm information, namely, the share of other study participants who intend to receive COVID-19 vaccinations, influences a student's perceptions of COVID-19 and stated intention of vaccination.
Despite an enormous policy response, opioid prescribing remains well above historical levels and harms from opioids continue to mount. Nearly all states have Prescription Monitoring Programs (PMPs) to facilitate safer prescribing of opioids and other drugs, but research suggests these systems only deliver benefits when health care professionals are required to use them. Even with PMP mandates in place, providers may be unaware of the dangers of co-prescribing opioids with benzodiazepines or gabapentinoids, which include increased risk of overdose and death. Working with the Minnesota state government, we will mail letters to guideline-discordant opioid prescribers that either highlight an upcoming legally mandated requirement to check the PMP before prescribing an opioid, inform and edu...
We conduct randomized survey experiments with US and Canadian residents to study attitudes toward market-based transactions, with a specific focus on whether and how people perceive and elaborate tradeoffs between competing values and goals. In our survey, participants will express their views and preferences over scenarios where companies increase the prices of certain goods in particular circumstances and scenarios where public authorities prohibit these price increases. Our sample will include 4,000 Americans and 4,000 Canadians and it will be representative of the respective populations in terms of gender, race and ethnicity, age, and educational attainment.
In this work, we are partnering with Contra Costa Health Services (CCHS), the department of health in Contra Costa County, CA, to measure COVID-19 vaccinations and other COVID-19 related preventive health behaviors in the county’s Medicaid managed care population. Our work will test ways to increase COVID-19 vaccine uptake. We hypothesize that small financial incentives and other low-cost behavioral nudges can be used to increase vaccine uptake and reduce disparities in uptake among diverse racial/ethnic minority populations.
Containing a pandemic, like the current Covid-19 pandemic, requires people to get vaccinated and to avoid unnecessary physical interactions with each other—that is, they have to stay at home and refrain from many social activities they normally like to undertake in the company of other people. This is a large-scale cooperation problem, where (some) people may have some incentives to break the rules for self-interested reasons but are thereby undermining the collective efficacy of containment strategies. Here, we are interested in the behavioral dimensions of people’s decisions to get vaccinated or not and to stay at home or not. There are several potentially relevant behavioral dimensions: People’s pro-social inclinations, their patience and risk preferences, their trust in the authorit...
A sample that is representative for the German adult population is drawn and randomly assigned to five experimental conditions that differ in the amount of true information given prior to a decision whether and at what time to retire an EU ETS allowance at a financial cost. The information describes the market stability reserve (MSR) and its implications on how the timing of retirement influences the actual amount of greenhouse gas emissions saved. The level of detail ("complexity") of the description is manipulated across the experimental conditions. The hypothesis is that increasing levels of complexity increase the willingness to delay allowance retirement for a higher climate benefit, but reduce the overall willingness to voluntarily abate by retiring an allowance.
This study presents new evidence on the gendered effects of social safety net programs, in the context of the Nigeria National Social Safety Nets Project (NASSP). The program has three components: 1) a basic unconditional cash transfer, 2) a top-up conditional cash transfer with behavioral change training, and 3) a livelihood support component comprising life skills and business skills training complemented by a lump sum productive grant. This study will evaluate the relative impacts of receiving Package 1 (component 1 alone), Package 2 (components 1 and 2), or Package 3 (components 1, 2, and 3). This evaluation will provide new evidence on scalable strategies to implement targeted government-led cash transfers and sustainable support for graduation out of poverty. It will especially fu...
Export-led growth is the dominant contemporary developmental paradigm. Export Promotion agencies and international donors operate programs around the world to help firms enter global value chains and access foreign markets. Compliance with quality criteria is one key mechanism that is assumed to condition firms’ success in this endeavour. We collaborate with the Tunisian Ministry of Industry and the German Metrology Institute (PTB) to test how to stimulate small and medium sized enterprises’ (SME) use of quality assurance services for exporting. For this purpose, we develop a program “Appui Qualité Export” to mitigate three barriers of SMEs under-consumption of quality assurance service: SMEs lack information, SMEs lack competences to identify their needs for export quality assurance an...
The impact of the COVID-19 pandemic has affected the educational sector worldwide. One of the consequences is also psychological distress among teachers and students at the university levels of Bangladesh along with many other socio and economic impacts of the pandemic. In this regard, we plan to conduct a randomized tele-counseling intervention aimed to lower the mental health impact of COVID-19 on both teachers and students in Bangladesh. We expect to find that by providing mental support to participating individuals will improve their mental health condition compared to the ones in the control group. We also hope to find affects on other secondary outcomes such as, their learning outcomes, well-being and productivity due to the tele-counselling intervention.
Based on theoretical predictions, I conduct a laboratory experiment to explore whether (a) self-image concerns are reference-dependent and (b) loss aversion applies to self-image concerns. I let subjects work on an IQ test, a self-image-relevant task, and induce an exogenous shift in complexity designed to put them at either gain or loss in self-image. Then, I elicit their willingness to acquire feedback. Considering potentially asymmetric belief updating, I analyze whether subjects who experience loss in self-image are more likely to acquire feedback compared to those with a loss in this domain.
