Do Digital Learning Platforms Close or Widen Learning Gaps? Evidence from Khan Academy in Lima’s Public Schools

In progress

Riega, S.

Studies whether educational technology substitutes for or complements students’ existing skills, using the staggered rollout of Khan Academy across public schools in Metropolitan Lima. The project asks whether learning gains concentrate among students who start closer to grade level, and whether the returns to the platform rise with a school’s capacity to implement it. Identification combines staggered difference-in-differences with the program’s eligibility thresholds.

Abstract

This research identifies women in urban Peru who were at risk of losing their jobs in 2020 and characterizes them before they became unemployed. I use a penalized logit model, trained on the National Household Survey (ENAHO) panel from 2016 to 2019, to predict women's risk of job loss. The model's predictions are then validated against the 2020 data to check whether the predicted job losses actually occurred.

When Migrating Is Not Enough: A Comparison of Migrant and Non-Migrant Job Quality in Urban Peru between 2019 and 2020

2021

Delgado, D. & Riega, S. (2021). Cuando migrar no es suficiente: una comparación de la calidad del empleo de los migrantes y no migrantes en el Perú urbano en el 2019 y 2020. Económica, (13), 101-121.

Abstract

This research seeks to analyse the job quality of interdepartmental migrants in urban areas during 2019 and 2020. Job quality, under the decent work approach, encompasses dimensions of workers' well-being. After constructing an index and finding that job quality deteriorated, we find, using a generalised ordinal logit, that there is no relation between being a migrant and job quality. Nonetheless, there are other sociodemographic characteristics that migrants usually share which are linked to the lowest job quality.

The Education Crisis and the Poverty of Learning in Peru

2020

Cóndor, P. & Riega, S. (2020). La crisis de la educación y la pobreza del aprendizaje en el Perú. Economica - Boletín de Investigación N° 7.

Abstract

This article focuses on the quality of education received by primary school students in terms of reading skills. It introduces the concept of learning poverty and estimates two indicators using the FGT method to understand the educational crisis. The results show a high incidence of learning poverty among fourth-grade students in 2016 and 2018, especially in rural and state areas. Two additional measures, the gap and severity of learning poverty, reveal an increase in both between 2016 and 2018.
