Repeated games with a long-lived player facing a sequence of short-lived players has, sins these games were first studied in Fudenberg and Levine (1989), been the focus of much theoretical work. In more recent years these models have received much attention due to their application to trade on online platforms such as Ebay and Amazon (which is becoming increasingly important). Like the more studied case of two long-lived players, the case with one long-lived player also suffers from multiplicity. Thus, while it is clear from a theoretical perspective that repeated interactions can help long-lived and short-lived players coordinate on mutually beneficial outcomes, it is unclear how this will come about. We set out to experimentally study strategy choices in repeated games with lon...
This impact evaluation aims to measure the causal impact of the ILO’s Get Ahead business training programme on the profitability, growth and survival of female-owned businesses in Kenya, and to evaluate whether any gains in profitability come at the expense of other business owners. To do so, the evaluation will use a randomized control trial (RCT) methodology with a two-level randomized experiment: randomized selection of villages, and of individuals within villages. The study works with 3,538 individuals in 157 markets. In addition to measuring the impact of this training program, individuals assigned to training are also then randomly assigned to one of three different invitation choice structures to measure the extent to which variations in the way in which people are invited to t...
Many critical real-world choices—ranging from corporate board investments to financial regulatory policies—are made by groups rather than isolated individuals. Crucially, these collective decisions are rarely simple; they routinely involve multi-dimensional settings where outcomes are both uncertain (risky) and delayed in time (intertemporal). While standard economic theories often assume a frictionless aggregation of preferences, real-world committees operate under specific formal protocols: institutional voting thresholds and asymmetric distributions of voting power.This study conducts a controlled laboratory experiment to systematically investigate how formal institutional designs shape collective choice in these complex environments. We implement a randomized 2 X 2 between-subject f...
This study examines whether individuals’ responses to artificial intelligence depend on the identity dimension through which they interpret technological change. Motivated by a two-dimensional framework in which individuals can identify with an economic group or a cultural group, participants first report their expectations about the consequences of AI and are then randomly assigned to reflect on their economic identity, cultural identity, or a no identity baseline. We examine whether inducing identity along different dimensions changes AI-related opinions and donation allocations across organizations addressing different economic or cultural consequences.
This field experiment studies the supply side of the economics of public procurement by lowering the cost of finding and preparing a bid and observing what firms then do. Croatian firms that already bid for public contracts are surveyed and randomly assigned to three weeks of free access to an integrated procurement platform, or to a waitlist receiving identical access three months later. The platform is an artificial intelligence specialized for public procurement: it matches notices to the firm's profile, reads tender documentation and extracts the award criteria, assists in preparing submission documents, and adds work ow management and analytics. The waitlist arm receives nothing in the meantime, so the comparison is against the public register and whatever general-purpose artificia...
This study tests whether providing local government officials with better information and non-financial recognition can improve the allocation of public drinking water wells in rural Bangladesh. Naturally occurring arsenic in groundwater affects tens of millions of people in Bangladesh and poses major health and economic risks. Each year, the government installs a limited number of deep wells to provide arsenic-safe water, but these wells are not always placed where they would benefit the most people. In this randomized controlled trial, 200 Union Chairpersons, who dictate the allocation of governmental wells within their jurisdiction, are cross-randomized into either receiving an access to a web-based planning tool and/or receiving an incentive to prioritize high-arsenic regions wit...
Experimental research in Bangladesh by Lee et al. (2018), now published in the American Economic Journal: Applied Economics (AEJ: Applied), showed promising positive impacts of the introduction of mobile money to urban migrants and their households at origin. In this project, we propose to expand the scope of the study to test the external validity of the results from Lee et al. (2018) in the subcontinent in two ways; first, through the use of a larger sample of migrant-household pairs in Bangladesh, and second, by including sites in Pakistan and India. This study will make use of a randomized control trial (RCT) design in each country, to study the impact of a deliberately-designed program in each country, and not a simple replication of the original experiment. Comparing the outcomes ...
The study investigates a causal relationship between the Alphabetisation Policy Improvement Program - a specific set of results-oriented school management practices, such as teachers’ continued training - and student literacy in the initial grades of state-run schools in Rondônia state, northern Brazil. The program is led by the Court of Accountability of Rondônia (TCE-RO) and twenty-two Municipal Secretariat of Education from twenty-two municipalities of the Rondônia state. One hundred and fifty schools were selected from these 22 municipalities to participate in the program. Schools within each city were randomly assigned to the treatment and control groups. The implementation should last two years. At the end of the program, a cross-section analysis will be conducted to assess possib...
Educational attainment is a key determinant of health and economic outcomes. The period of late adolescence is a critical period of development when changes in educational processes can have dramatic consequences over the life course. However, despite major progress made in primary education, only around 40% of adolescents reach the last grade of lower secondary school in sub-Saharan Africa (SSA) today. Average educational attainment remains lowest among women in SSA, particularly in central and western SSA. The primary objective of this project is to identify the most effective strategies to reduce these disparities and to improve secondary school attendance. Building on the key insights and recommendations of the 2020 Global Education Evidence Advisory Panel, we will conduct a pilo...
Despite significant gains in financial access across Low- and Middle-Income Countries, financial health and resilience remain critically low among informal sector workers, largely due to exposure to uninsured health shocks. In Nigeria, only about 3% of adults aged 15-49 have any form of health insurance, leaving the majority vulnerable to catastrophic out-of-pocket expenditures that affects business viability and loan repayment. This study provides causal evidence on the impact of bundling health insurance with microfinance loans on the financial outcomes of informal micro and small business owners in Edo State, Nigeria. In partnership with a microfinance institution and the Edo State Health Insurance Commission, eligible interested clients are offered a voluntary bundled product combin...
