We study gender differences in child support rulings by judges in cases where defendants (fathers) may work in either the formal or informal sector. Our identification strategy exploits the random assignment of cases to courts presided over by individual judges. We find that female judges award child support amounts that are 0.18 standard deviations lower than those awarded by male judges. When focusing on defendants working in the informal sector (who constitute over 70% of the cases), the gap appears to stem from female judges’ greater skepticism toward what they perceive as inflated claims by plaintiffs, influencing their beliefs about defendants’ earnings. We further explore four potential mechanisms behind the gap that also include formal cases: bias against female plaintiffs, workplace masculinization, interactions with other judge characteristics, and differences in legal objectives. We do not find conclusive statistical support for these mechanisms.

While existing evidence shows that nation-building policies unify societies, little is known about how and what makes some societal groups to resist them. We examine this in the context of the post-Mexican Revolution (1920s–1950s), when the new state implemented a nation-building policy to eliminate Indigenous cultures and identities by increasing connectivity via transport infrastructure. In a difference-in-differences design, we leverage heterogeneity in the exposure to pre-colonial political centralisation as a proxy for the ability of Indigenous populations in mobilising to resist national integration. We find that the expansion of transport infrastructure was lower in municipalities with a stronger efficacy of Indigenous mobilisation. We demonstrate that this underprovision of public goods can be partly explained by Indigenous identity preservation and high abilities for collective actions.

We study the effect of a randomized one-on-one remote phone tutoring program implemented between 2021 and 2023. The intervention reached almost seven thousand students in seven Latin American countries: Argentina, Brazil, El Salvador, Guatemala, Mexico, Paraguay and Peru. The program targeted students with low initial learning levels and focused on foundational numeracy skills using a differentiated instruction approach. We find that assignment to tutoring increased student test scores by 0.2 SD. Tutoring benefited all students, with no differential effects by gender, age, socioeconomic status, or baseline scores. We find suggestive evidence that students who reported difficulties with concentration or memory may have benefited more. Finally, we find that students with lower initial performance exhibited larger improvements in more basic mathematical operations, whereas those with better performance at baseline saw larger gains in more complex operations. This underscores the importance of offering differentiated instruction based on students’ initial performance.

In recent years, a growing literature has examined the potential of multifaceted, intensive graduation models that address multiple barriers constraining households’ exit from poverty. In this paper, we present new evidence from a randomized trial of a lighter-touch (less intensive) graduation model implemented in Ethiopia. The primary experimental arms are a bundled intervention including a transfer valued at PPP $374 (randomly assigned to be cash or equivalent value in poultry), training, and savings groups; a simpler intervention including training and savings groups only; and a control arm. We find that three years post-baseline, the intervention inclusive of the transfer leads to increases in savings and cash income from livestock, though there is no shift in consumption or food security and very little evidence of asset accumulation; these effects are generally consistent regardless of the modality of the transfer (cash versus poultry). The effects of training and savings groups alone are minimal.

This paper examines whether improved financial access can mitigate the constraints imposed by social identity on entrepreneurship among under-privileged caste groups in India. Using a novel dataset on Indian villages and their proximity to bank branches, we find that closer access to a bank branch significantly enhances entrepreneurial activity among Scheduled Castes (SCs) in non-agricultural sectors, especially in those sectors that are traditionally dominated by upper-caste groups. These findings are more pronounced in villages where the improvement in proximity was plausibly exogenous, resulting from the RBI's Bank Branch Expansion Policy of 2005. For Scheduled Tribes (STs), however, financial access is associated with a gain in the size of hired employment within enterprises. Exploring several mechanisms, we find that these effects are primarily driven by credit uptake. Overall, our findings highlight the potential of financial inclusion in breaking rigid social norms around the entrenched caste-based occupational segregation and promoting more equitable economic participation in India.

This paper provides causal evidence on the economic impact of central-to-local government transfers in a developing country context. We exploit plausibly exogenous variation in municipal transfers generated by a 2018 reform to Ecuador’s intergovernmental allocation formula. Using a design-based instrumental variables strategy, we estimate that a 1% increase in government transfers led to a 0.94% increase in total business sales in 2018 and 1.05% in 2019. The strongest effects are found in non-VAT sales. Mechanism analysis shows that transfers boost local economic activity mainly through increased recurrent and capital spending, particularly wages and procurement, suggesting that well-designed transfers can act as effective local demand stimuli.

One way to advance our understanding of individual differences in decision-making is to study the development of children's decision-making. This paper studies the causal effects of daycare attendance on children's economic preferences and decision-making abilities, exploiting a lottery system that randomized admissions into oversubscribed daycare centers in Rio de Janeiro. Impacts are estimated separately for boys and girls. Daycare attendance increased the decision-making quality of boys by 0.16 standard deviations (SD) and the aversion of girls to disadvantageous inequality (i.e., having less than one's peer) by 0.23 SD. It also decreased the self-control of boys by 0.19 SD.

Many countries face challenges due to the geographical mismatch of energy supply and demand. Traditional high-voltage transmission systems have limited capacity to meet the rising need for transregional electricity transfer. China's recently developed ultra-high-voltage (UHV) transmission system presents a promising solution. This study quantifies the pollution reduction effects of UHV transmission using firm-level data on emissions and energy consumption. Employing a staggered difference-in-differences (DID) design that accounts for regional heterogeneity, we find that the operation of UHV lines reduces firms' total SO2 emissions by 16.8 % on average and emission intensity by 17.1 %. Mechanism analysis indicates that the UHV system provides low-cost and stable electricity, facilitating electrification in power importing areas. It also boosts hydropower generation in power exporting areas, displacing thermal power in power importing areas. Welfare analysis shows that incorporating environmental benefits reduces the investment payback period of UHV projects from 28 years to 5 years at a 2.5 % discount rate. These findings contribute to a comprehensive evaluation of transregional electricity infrastructure, particularly in developing economies where grid modernization is a key energy policy goal.

Carbon taxation is suggested as an efficient instrument for the clean energy transition. However, high resulting prices for coal and electricity could adversely impact industrial performance and employment by raising production costs. Integration of renewable energy in the electricity grid could stabilise electricity prices. We estimate the elasticity of substitution between labour and electricity among the formal and informal manufacturing sector in India. The results show labour and electricity are strong complements in manufacturing, with elasticities significantly below one, which suggests a carbon tax that raises electricity prices may reduce employment in firms. On the contrary, we find high substitutability between thermal (coal) and renewable energy-based electricity generation, with the elasticity of substitution estimated at 2.0–3.3. Our results suggest that electricity derived from renewable energy sources and supplied to industry at affordable prices could mitigate the adverse effects of a carbon tax in Indian industry.

While many of the world’s poor consume inadequate calories with low nutritional value, there has been little work on how this may shape their behaviors and productivity. Using lab-in-the-field and field experiments in the context of a floriculture plant in Ethiopia, this study investigates the effects of a nutrition support program on behavioral outcomes—stress, prosociality, cooperation, and attention—and productivity. We find that nutrition support relieves stress and decreases prosociality, exhibiting a pattern of hedonic adaptation over time. We do not find evidence for improvements in labor productivity.
