I'm a Technical Assitance Advisor in Tax Policy Division (T1) of the Fiscal Affairs Department at the International Monetary Fund (IMF).
I do applied research using large administrative data sets. Recent projects include estimating the effect of a computerized risk-based evaluation system to curb input tax evasion in VAT, measuring evasion through bunching behavior at minimum value addition kinks, evaluating the impact of penalizing firms for sales to informal sector through an extra tax, analyzing the deterrence effect of randomized audits and behavioral impacts of using large firms for tax compliance.
