We investigate Italy’s centralized teacher assignment system where teachers can rank “geographical regions”, leading to ties in their rank order lists (ROLs). We show that the way ties in teachers’ ROLs are resolved in the current assignment mechanism systematically violates teachers’ priority rights and results in justified envy. We propose a new mechanism, Deferred Acceptance with Hierarchical Choice (DA-HC), which is strategy-proof, eliminates justified envy, and Pareto improves over the benchmark deferred acceptance mechanism with simple tie-breaking (DA-STB). Using administrative data, we provide evidence that DA-HC can potentially bring significant welfare improvements over the benchmark DA-STB.- “Best Paper Award” at the 25th ACM Conference on Economics and Computation (2024)

Policy Report [PDF] [Economics Blog]
Most secondary schools in England are able to design the rules for which pupils have priority when the school is over-subscribed. This could be positive or negative for inclusivity, depending on schools’ choices. In this context, we study the detailed rules for each secondary school in England. Our main findings are that, first, geography (still) determines admission to most over-subscribed schools. This matters for social mobility, as some households are priced out of high performing schools due to higher property prices around the school. Second, despite explicit financial incentives, only a small minority of schools give priority to pupils eligible for the Pupil Premium, and this priority is meaningful only in a few dozen schools. Third, the few schools with ‘innovative’ admissions arrangements could inspire other schools to implement feasible ‘tried and tested’ reforms. Free schools appear to be leading these ‘innovative’ admissions arrangements. Finally, in the complex system of multiple school types and diverse admissions arrangements, parents in some areas lack the required information to make informed school choices.

This paper explores the effect of language proficiency on Math achievement for ten-year-old second-generation immigrant children in Italian primary schools. Especially for these children, proficiency in the host country language is the prerequisite for the acquisition of any other skill. However, using an instrumental variable strategy that exploits the heterogeneity in birth dates and the variation in linguistic distances, we find that they face a trade-off between learning Italian and learning Math. The linguistic literature offers an explanation based on the existence of a language proficiency threshold that must be crossed to understand the classes. On this basis, we develop a simple model of skill production that provides theoretical foundations for our results and a unified framework for interpreting the mixed findings in the literature. We present empirical evidence that the trade-off arises when proficiency is below the threshold commonly adopted to indicate a sufficient command of the Italian language, which happens for 59% of our sample. Enabling these children to catch up requires substantial investments in education since, when a sufficiency threshold must be crossed, marginal improvements are ineffective, rendering the proficiency gap permanent and fostering social exclusion and inequality.
