Education Spending and Economic Growth: Short- and Long-Term Effects in a Global Panel. With Arturo Galindo and Dante Contreras. Review of Development Economics, 2026.

Abstract
This paper examines the short- and long-term effects of education expenditure on economic growth using a global panel of 107 countries from 1970 to 2019. Employing a CS-ARDL model with an error correction framework, we estimate dynamic responses to aggregate and disaggregated real education spending across primary, secondary, and tertiary levels. Results show that public investment in education has a statistically significant and positive impact on real GDP per capita, both in the short and long run. The long-run elasticity is highest for aggregate expenditure and comparable across primary and secondary education, though smaller for tertiary education. We further explore heterogeneity in long-run effects and find that higher educational achievement, proxied by PISA scores, amplifies the growth impact of education spending. Simulations confirm that countries with higher PISA scores experience faster and stronger returns to investment. These findings underscore the role of education quality in enhancing the productivity of public education spending and support targeted policy efforts to improve both the quantity and quality of educational investment.

Generative Artificial Intelligence in Schools: Institutional Readiness and Digital Competencies in ICILS 2023. Papeles de Economía Española, Issue 184, FUNCAS. With Christopher Neilson.

Abstract
This study analyzes schools’ institutional readiness to adopt generative artificial intelligence (GenAI), using data from ICILS 2023. Given the limited empirical evidence on its adoption in schools, we propose a novel measurement approach using principal component analysis (PCA) that identifies three key dimensions: positive expectations, perceived risks, and institutionalization of GenAI use. We observe consistent socioeconomic gaps across countries: schools serving more vulnerable students are systematically less prepared to adopt GenAI, which could exacerbate educational inequalities if the technology improves productivity. We also find a positive statistical association between institutional readiness and students’ digital competencies. Our main contribution is a replicable metric for comparative research and monitoring, while also underscoring the importance of education policies focused on technological equity.

Working Papers

Designing Smart School Choice Recommendations: Heuristics for Sure Alternatives. Master's thesis.

Abstract
I propose a school choice policy to recommend guaranteed school alternatives for students left unassigned under stable matching. By leveraging revealed preferences, I design a personalized recommendation mechanism that offers voluntary allocations to unlisted but potentially desirable nearby schools. Using rich administrative data from the Chilean school choice system, I simulate the proposed intervention across the full applicant pool to assess its general equilibrium effects on the resulting allocations. Results indicate that in the main round, the mechanism is able to (i) reduce the proportion of unmatched applicants by up to 50%, (ii) increase expected aggregate utility by 2–6%, and (iii) concentrate utility gains among applicants who apply to oversubscribed programs. To facilitate implementation, I develop a targeted submarket implementation that yields comparable improvements while preserving all original assignments. Overall, the policy offers a cost-effective and scalable solution to improve match outcomes by redistributing excess demand within centralized assignment systems.

Heterogeneous Effects of Lengthening the School Day on Students' Academic Achievement: A Longitudinal Study of Full Day School Reform in Chile. With Dante Contreras and Ignacio Riveros.

Abstract
This paper studies the effects of a large and gradual increase in the Chilean school day over students’ academic achievement. We exploit a gradual and exogenous variation produced by the reform with an innovative measure of exposure to longer school day treatment. Using longitudinal data at an individual level and a fixed-effects strategy, we find that in the long run, this reform had no relevant effect on students’ standardized test scores nor higher education enrollment. However, this paper found heterogeneous response to additional instructional time by gender, type of school, and socioeconomic status. These results are robust to the inclusion of several covariates and insensible to the cohort selection.

Policy Reports

Extended School Day: Evidence, Implementation, Challenges and Recommendations. Technical note N° IDB-TN-2792. With Dante Contreras.

Abstract
This study reviews evidence on implementing the extended school day (ESD), a policy adopted across Latin America to improve academic results and educational quality, especially in schools serving vulnerable students. Drawing on the experiences of Chile, Colombia, Pernambuco (Brazil), and Portugal, it finds that ESD requires high funding and maintenance costs and detailed planning, and that its effects on standardized academic performance are marginal in most settings, though Pernambuco stands out as a success. Beyond test scores, the region shows ample evidence of socioemotional, family, and community benefits, including lower school dropout and teenage pregnancy and greater female labor-force participation. The note discusses the main implementation challenges (infrastructure, cost, organizational planning, national coordination, pedagogical redesign, and community engagement) and proposes strategies to mitigate them, such as starting with pilot programs and phasing in the reform gradually.

Cost Analysis: Charging Infrastructure for Electric Vehicles. Technical note ESA, Ministry of Energy. With Ignacio Rivas and Javier Contador.

Abstract
Published by Chile’s Energy Sustainability Agency (AgenciaSE) for the third consecutive year, this report analyzes the costs of charging infrastructure (CI) for electric vehicles in Chile, with particular attention to projects on public land and volume-based discount estimates across categories. Based on primary data collection, it documents a rise in prices over the past year, most pronounced for higher-power projects, linked to global inflation, higher transport costs, and supply-chain constraints. It characterizes the Chilean CI market as incipient but growing, with new infrastructure providers, more trained installers, and emerging cost-optimization strategies, and aims to reduce information asymmetries and foster a more competitive charging market.

Targeted Vouchers, Competition Among Schools, and the Academic Achievement of Poor Students. Job Market Paper by Christopher Neilson. Conditionally accepted at Econometrica.

Abstract
I develop a model of supply and demand with imperfect competition to study the primary education market in Chile. I use this framework to analyze how voucher policy affects incentives for schools to supply quality. First, I provide evidence that introducing a voucher targeted at poorer students led schools to improve quality. Next, I estimate demand and use the estimates to quantify the mechanisms that incentivized for-profit schools to improve. My estimates indicate that under a flat voucher system, schools leverage market power to reduce quality below the competitive benchmark, particularly in the poorest neighborhoods where competitive incentives are weakest. My results indicate the introduction of a targeted voucher policy reduced schools’ market power and increased marginal revenue, improving observed school quality. These findings provide evidence that targeted vouchers enhanced academic achievement and equity by increasing resources for schools and intensifying competition where it was previously lacking.

Approximating the Equilibrium Effects of Information Interventions. Claudia Allende, Francisco Gallego, and Christopher Neilson. Resubmitted to Review of Economic Studies. Supplemental material.

Abstract
We study how information about school quality affects school choice and what happens when such an intervention is scaled up. In a randomized trial in Chile, families offered a short video and personalized school report card choose schools with higher test scores and value added. Treated children score 0.2 standard deviations higher on standardized tests, with gains persisting sixteen years later. We embed the experimentally identified demand shift in a structural model of school choice and competition to study equilibrium effects at scale. Capacity constraints and centralized assignment attenuate the demand-side gains, but the same shift in demand strengthens schools’ incentives to improve quality, and the supply response more than offsets the congestion effect. Extrapolating directly from the experiment would understate, not overstate, the policy’s equilibrium impact. We use the model to guide the design of a follow-up cluster-randomized experiment, focusing on the tradeoff between statistical power and equilibrium spillovers.

Monetary policy surprises on the banking sector: The role of the information and pure monetary shocks. Felipe Beltrán and David Coble. Latin American Journal of Central Banking, 2024.

Abstract
This paper analyzes how monetary policy surprises in Chile affects the real and financial sector separating between a pure monetary policy shock and an information shock. Using inter-day movements of futures of interest rate in the banking system, we identify an information shock when labor data is released and a pure monetary policy shock when the central bank reveals their interest rate decision, and their effects are quantified through an external vector autoregression model. Our results suggest that a pure monetary policy shock produce an appreciation of nominal exchange rate, and contractionary effects on the economy. However, an information shock does not necessarily produce adverse effects. This paper contribute to the literature in two dimensions: studying the effect of the main driver behind the central bank announcements, and their transmission to the banking sector and consequently to the real and monetary sector.
