In the current nudging literature, several have called for more research on the combination of behavioral interventions as a promising avenue to see larger effects (Nisa et al., 2019), and it has also been claimed that combinations of nudges and monetary interventions may be particularly effective in promoting pro-environmental behavior (see e.g. Alt et al., 2024). Most of the research on policy mixes has been done in the energy domain (Allcott et al., 2014; Drews et al., 2020; Fanghella et al., 2021) and there is a lack of research on policy mixes in the food domain. Furthermore, the existing research on policy mixing in the food domain mainly focuses on promoting healthy food products (Ahn & Lusk, 2021; Papoutsi et al., 2015; Vo et al., 2022). The purpose of this study is, first, to i...
This study is an update from our initial equal opportunity experiment. The initial equal opportunity experiment is now considered a pilot experiment. Equal opportunity has wide applicability throughout society. It touches upon access to education, employment, legal representation, etc. Given that equal opportunity has different meanings to different people (i.e., equal opportunity in outcomes, resources, access, etc.), we use a simplified definition based on the different types of equal opportunity mentioned in Arneson (2018). We define equal opportunity to mean that individuals should have similar access to “resources” except when one’s innate ability leads to a difference in resource allocation. This project explores how economic inequality created by an institution affects pro...
We run a choice experiment that induces exogenous variation in job attributes. The key features of the experimental design follows Maestas et al. (2023). We aim at identifying workers' willingness to pay for firm training. Additionally, we investigate willingness to pay for other job attributes, in particular working hours, flexibility, autonomy, contract type and leadership.
Does a training program for factory managers, supervisors, and workers lead to better performance and worker outcomes in factories that are planning to introduce a pay incentive system? We will also test whether any performance or worker outcomes are moderated by social norms deterring sexual harassment, rehumanization of workers, power dynamics, incentive pay, and accountability. We first looked at this question in a study of a management training program in Vietnam. Now we are looking at effects of both the manager training and a whole-workforce rehumanization training in factories in Bangladesh. We also plan to look at whether rehumanization of workers affects supervisors' information processing.
Competitions, or competitive incentives, have been shown, and are used in various real-world settings, to induce higher productivity and output. At the same time, in settings where individuals are able to affect the productivity or output of others, competition can also lead to individuals sabotaging one another. There are two main reasons as to why individuals sabotage when engaged in a competition. First, competition ties one’s payoff (e.g., earnings) to relative performance. This introduces a monetary incentive to sabotage others as it allows one to increase their likelihood of achieving a better relative performance and hence, a higher payoff. Second, being engaged in a competition alters an individual’s psyche and puts them in a competitive state of mind. This might in turn increas...
Plastic waste is a global threat. Prior studies find that “green nudges” are effective in reducing the use of single-use cutleries (SUC) in food deliveries. To our surprise, we find, in a pilot study, that restaurants still give out SUCs in food deliveries despite customers choosing the “no cutlery” option. The objective of the study is to explore why restaurants still give out SUCs and potential mechanisms to reduce this behavior. We further explore short-term and long-term effects of the treatments. Our study intends to provide actionable insights that could lead to more successful environmental policies and thereby contributing to the global effort to mitigate plastic waste.
As company emissions significantly contribute to climate change, government organizations are implementing policies to encourage companies to reduce their carbon footprint, such as the European Union's Sustainability Act. To comply with these policies, one proposed method is to direct employees’ attention to sustainable options using digital nudging. However, the literature on the effectiveness of digital nudging in promoting sustainable decision-making remains inconclusive. In addition, there is a lack of knowledge about the potential spillover effects of digital nudging on subsequent sustainable behavioral intentions. Our research aims to fill this gap by investigating the effects of digital nudging to guide employees to more sustainable decisions within a two-stage decision-making ...
Workers periodically worry about issues unrelated to the job, such as dwelling on whether the front door is locked or stress induced from other factors. Similarly, workers are routinely under pressure to meet their job’s demands, increasing productivity to meet deadlines, or achieve performance goals. Previous work has studied the response to incentives under both these two sources of stress experienced by the workforce in isolation, characterizing non-work-related stressors as distractions and work-related pressures as performance under pressure. There is no research that we are aware of directly testing whether these two roots of stress differentially affect the way in which workers respond to incentives. The main objective of this study is to investigate whether job related, and non...
The Ethiopian government initiated a Community-Based Insurance scheme (CBHI) in 2011 to enhance financial protection for the informal sector. As of 2020, 8.4 million households were enrolled in the scheme. However, one of the CBHI's challenges is that households contribute an equal amount of premium (flat-rate contribution in majority of the settings across the country) regardless of their economic status and ability to pay. This adversely affected the lower-income households, sustainability, and equity of the program. To address this challenge, a new policy initiative, a sliding scale (SS-CBHI) contribution system based on households’ economic status is under consideration. This study is intended to evaluate the impact of introducing the new policy initiative using a Randomized control...
Preterm birth is the leading cause of childhood mortality and developmental disabilities and costs $26 billion annually. A critical modifier of preterm infant health and development is maternal presence during the birth hospitalization, which facilitates breast milk provision, participation in skin-to-skin care and allows mothers to benefit from training in post-discharge infant care practices. However, these benefits can only be realized if mothers are able to visit their hospitalized preterm infants for several hours per day, actively engage in caregiving and receive training from staff during the many weeks of a typical preterm birth hospitalization. Regularly visiting a neonatal intensive care unit (NICU) requires mothers to shoulder significant costs, including parking, childcare f...
