Progressive wealth taxes may be difficult to enforce if wealthy individuals underreport their wealth, but disclosure incentives and greater enforcement can improve tax collection.
Juliana Londoño-Vélez presents her work with Javier Avila-Mahecha which uses rich administrative data from Colombia and leverages a government-designed program for voluntary disclosures of hidden wealth, as well as the threat of detection triggered by the Panama Papers leak.
