The elasticity of taxable income is a key tax policy parameter that plays an important role in the formulation of tax and transfer policy. This paper extends work by Kemp (2019) by using a new panel of individual tax returns and the phenomenon of 'bracket creep' to produce updated estimates of...

Since Sandmo (1981), many articles have analyzed optimal fiscal policies in economies with tax evasion. All share a feature: they assume that the cost of enforcing the tax law is exogenous. However, governments often invest resources to reduce these enforcement costs. In a very simple model, we...

The COVID-19 pandemic has led to an increase in public debt in most countries. This will increase fiscal pressure in the future. We study how the shape of the optimal nonlinear income tax schedule is affected by this increase. We calibrate the workhorse optimal income tax model to five European...

This paper explores the effects of fiscal policy in the presence of a VAT evasion channel, and then compares and contrasts two regimes - the exogenous vs. optimal policy case. To this end, a dynamic general-equilibrium model, calibrated to Bulgarian data (1999-2014), is augmented with a...
