Compositional Synthetic Controls
Onil Boussim
When applying synthetic control to compositional outcomes (budget, vote shares), researchers commonly minimize Euclidean distances between raw shares. I propose constructing synthe…
Correcting sample selection bias with categorical outcomes
Onil Boussim
In this paper, I propose a method for correcting sample selection bias when the outcome of interest is categorical, such as occupational choice, health status, or field of study. C…
Identifying treatment effects on categorical outcomes in IV models
Onil Boussim
This paper studies population treatment effects when the outcome is unordered categorical, the treatment is binary, and the instrument is binary. I introduce an assumption called a…
Compositional difference-in-differences
Onil Boussim
Many causal questions involve outcomes distributed across mutually exclusive categories, such as votes by party or employment by status, where both category shares and the total qu…
Changes-In-Changes For Discrete Treatment
Onil Boussim
This paper generalizes the changes-in-changes (CIC) model to handle discrete treatments with more than two categories, extending the binary case of Athey and Imbens (2006). While t…
Correcting Sample Selection Bias in PISA Rankings
Onil Boussim
This paper proposes a method to account for sample selection (survivor bias) in cross-country comparisons. International assessments such as the Programme for International Student…
