Research project The impact of class size on educational mechanisms, health, and teacher hiring

This project aims to understand how class size impacts educational mechanisms, health and  teacher hiring. The project's first study combines detailed administrative and survey data from Spain  to investigate how class size affects (among other things) classroom environment, teaching  methods, parental involvement and student well-being. The project's second study investigates the  health effects of class size on students, parents, and teachers, along with its impact on their labor  supply. The project's third study investigates how Swedish schools hire new teachers when  receiving extra funding to reduce class sizes and examines its consequences for students'  outcomes.
