We exploit rules of class formation to identify the causal effect of increasing the number of immigrants in a classroom on natives’ test scores, keeping class size and quality of the two types of students constant (pure ethnic composition [PEC] effect). We explain why this is a relevant policy parameter although it has been neglected so far. The PEC effect is sizable and negative (16% of a standard deviation) on language and math scores. For first-generation immigrants, it is more negative (30% of a standard deviation). Estimates that cannot control for endogenous adjustments implemented by principals are instead considerably smaller.

Abstract
We exploit rules of class formation to identify the causal effect of increasing the number of immigrants in a classroom on natives’ test scores, keeping class size and quality of the two types of students constant (pure ethnic composition [PEC] effect). We explain why this is a relevant policy parameter although it has been neglected so far. The PEC effect is sizable and negative (16% of a standard deviation) on language and math scores. For first-generation immigrants, it is more negative (30% of a standard deviation). Estimates that cannot control for endogenous adjustments implemented by principals are instead considerably smaller.File | Dimensione | Formato | |
