  • Maternal Beliefs, Mental Health, and Economic Resources on Human Capital Accumulation in Early Life
    Last registered on July 20, 2024

    Using a novel locally grown health service delivery model in Bangladesh that tracks the universe of newly married couples and connects them to local health services, we aim to study whether targeting mothers early in pregnancy with three complementary interventions -- individually or in combination -- can improve their own wellbeing as well as their children’s developmental outcomes. Our outcomes of interest include women’s empowerment, parental inputs, physical and mental health, and children’s health and development.

  • The impact of pre-emptive home delivery of ORS + zinc on treatment for child diarrhea: a randomized controlled in Bauchi, Nigeria
    Last registered on July 19, 2024

    We will use a cluster randomized controlled trail to measure the effect of delivering oral rehydration salts (ORS) and zinc –– highly effective and WHO recommended treatments for child diarrhea –– to homes with children under the age of 5 years in Bauchi, Nigeria. Half of the 323 wards in Bauchi will be randomly assigned to receive the free deliveries and the other half will be the control group. We will collect data through household surveys continuously for 12 months following the deliveries. The primary outcome will be the probability that a diarrhea cases that occurred within 4 weeks of survey was treated with ORS. We will measure the average effect on ORS use over 6-months, over 12-months, and monthly. Results will be used to inform whether this intervention should be scaled-up nat...

  • Attitudes Towards Race and Ethnicity in the UK
    Last registered on July 19, 2024

    The project will use an online survey organisation to run a survey experiment that aims to understand the attitudes of a representative sample of the UK population, towards causes, consequences, and feasible policy solutions to persistent gaps in economic outcomes between ethnic/racial groups in the UK. The questions asked would focus on perception of economics differences along ethnic/racial lines, perceived understanding of the causes of the differences and attitudes towards possible policy solutions. The participants would be asked to complete an online questionnaire and the data collected would the answers provided by the respondents to the said questionnaire. The proposed method, an online survey, allows the collection of the data and will include an experimental variation that inv...

  • Financial Inclusion for Migrants (FIM)
    Last registered on July 19, 2024

    Our research project aims to comprehensively understand the demand and supply barriers affecting access to, usage of, and transition to various financial products among Venezuelan migrants. Additionally, we aim to gain insights into migrants' perceptions of financial inclusion and pertinent migrant issues. A pivotal aspect of this stage involves a nuanced examination of how engagement with the financial system may be influenced by perceptions of discrimination or the provision of information about its extent. To assess these dynamics, we employ an outcome telephone survey structured to include both a control group and a treatment group. These groups are formed through the random assignment of questionnaire sections eliciting perceptions on discrimination and providing information about ...

  • GALOP Information Nudge to improve the Implementation of Differentiated Learning (GINII)
    Last registered on July 19, 2024

    Previous research in Ghana has demonstrated the effectiveness of Differentiated Learning (teaching students at their level) on student learning. As a result, the Ghanaian Ministry of Education has decided to scale up differentiated learning to 10,000 schools in Ghana, an effort known as the Galop Initiative. Despite these efforts, the effective implementation of Differentiated Learning (DL) across the nation remains a challenge. Teaching in a differentiated manner demands additional effort, planning, and adaptability, making teacher motivation one potential barrier to implementation. Teacher motivation may be affected by their beliefs of whether or not students learn more effectively with differentiated learning compared to the status quo. The study seeks to assess whether providing inf...

  • Gender Bias in Professional Tennis
    Last registered on July 19, 2024

    We employ a novel experimental design to investigate gender biases in performance evaluations, specifically examining whether women receive less recognition for their successes and face harsher penalties for their mistakes compared to men. Utilizing advanced artificial intelligence-generated content (AIGC), we manipulate the perceived gender of players, allowing participants to evaluate identical performances attributed to different genders. This methodology isolates and measures the causal effects of gender bias. Our study involves Prolific participants assessing tennis highlights and unforced errors, ensuring evaluations are based solely on performance while varying perceived gender. Grounded in Regulatory Focus Theory, we explore how promotion focus (associated with ambition and risk...

  • Skills Mismatch: Sources and Consequences
    Last registered on July 19, 2024

    Skills mismatch, defined by the discrepancy between workers’ skills and job skill requirements, can have negative effects on workers’ income and career progression. Past research has studied its causes separately which include (i) workers not fully knowing their own skill levels; (ii) lacking of labour market information; (iii) lacking confidence and adherence to social norms. For example, female workers may perceive that a programmer is not a suitable job for women. The project will study the role of these three factors and their interactions on skills mismatch using a randomised controlled trial (RCT). The RCT involves giving participants who are final-year college students in Thailand different treatments. The three main treatments are as follows: providing information on individ...

  • Scaling Laws for Economic Impacts
    Last registered on July 18, 2024

    This study investigates the productivity impacts of thirteen generative artificial intelligence (AI) technologies with varying training compute sizes. By analyzing scaling laws, we measure how economic impacts evolve as the size of generative AI models increases. Our research is conducted in a real-world context, employing professional online translators to perform tasks akin to their routine professional work. Additionally, we explore the relationship between the skill-bias of technological change and the degree of automation. Our findings offer critical insights into the scaling effects of AI on productivity and the dynamics of skill-biased technological advancements in the labor market.

  • Testing a condensed methodology to estimate distributional preferences à la Fisman et al. (2007) – Follow-up Study
    Last registered on July 18, 2024

    Estimating individual distributional preferences has become a widely used technique in behavioural economics research. A frequently utilised methodology to do so has been put forward by Fisman, Kariv and Markovits (2007). In their methodology, subjects make distributional choices in 50 modified dictator games, which are then used to estimate two distinct utility parameters. One captures the relative weight for the own payoff (α) and the other describes an efficiency-equity trade off (ρ). In this study, we use the original and new data to explore whether we can reduce the number of distributional choices made by subjects whilst still accurately estimating preference parameters. Simulation results, already obtained by us, show high accuracy in estimating both parameters when using as few ...

  • Early Adopters, Peer Leaders and the Diffusion of Agroecological Knowledge
    Last registered on July 18, 2024

    Peer effects are a subject of increasing attention in many areas of economics research. Influence from peers can indeed generate social multiplier effects, whereby an initial investment targeting one small group can lead to larger changes, since individuals close to the target group tend to imitate them and learn from their experience. When it comes to the green transition in agriculture, the diffusion of new knowledge through peers could play a crucial role in promoting the adoption of agroecological practices. However, the conditions for successful peer learning in this context are still poorly understood. In particular, it is unknown whether the profile of the first individuals in peer groups to receive information affects its diffusion to other peers. To answer this question, we ru...
