We assess price dispersion in retail markets and its sources over time. Using a product-detailed price database, we document a consistent divergence of prices over time in retail markets in Uruguay: price dispersion increased by 3.1% in fifteen years. Next, we analyze microeconomic and...

This research analyses the firms' strategic choice of adopting an abatement technology in an environment with pollution externalities when the government levies an emission tax to incentivise firms undertaking emission-reducing actions. A set of different Nash equilibria - ranging from dirty to...

The study evaluates the effectiveness of a 12-week AI module delivered to non-STEM university students in England, aimed at building students' AI Capital, encompassing AI-related knowledge, skills, and capabilities. An integral part of the process involved the development and validation of the...

This paper develops a model that allows for heterogenous contemporaneous peer effects among different types of agents who are endogenously selected into different peer groups. Using our framework, we characterize the reduced-form coefficient in the peer effect literature and show that it is a...

To reduce the spread of COVID-19, schools closed to an unprecedented degree in the spring of 2020. To varying extent, students have moved between in-person and remote learning up until the spring of 2021. This chapter surveys the literature on the implications of school closures of primary to...
