We study the performance of the bunching-based elasticity estimator when income adjustments are lumpy. In our parsimonious model, taxpayers choose their preferred income from random opportunity sets. The model features the standard elasticity of taxable income and a single additional...

We incorporate a general model of frictions into the bunching-based elasticity estimator. This model relies on fewer parameters than the conventional approach, replacing bunching window bounds with a single "lumpiness parameter," while matching rich observed bunching patterns such as...

We introduce financial education that helps potential retail consumers of a suboptimal insurance product with shrouded attributes ask the right questions, and provide rules of thumb to evaluate theproduct. Our intervention reduces the potential demand for the suboptimal product. We use a model...
