The semi-dual income tax typically combines a progressive tax schedule for labour and pension income with low and often flat and differentiated nominal tax rates on some forms of capital income. This paper discusses the rationale for the adoption of semi-dual income tax in the taxation of...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...

We study the effect of reforms that close loopholes in the enforcement of the dividend-withholding tax (DWT). We focus on a Danish reform enacted in 2016, and compare Denmark to its Nordic neighbors. Our main outcome of interest is the quantity of stocks on loan. Before the reform all Nordic...

In recent decades, market power has increased substantially, according to multiple measures that describe industry concentration, mark-ups, and business profitability. While market power can generate benefits, it also raises vexing policy concerns, including the potential for adverse effects on...

The basic deterrence model of tax evasion is described, its main predictions are derived and limitations and flexibility are outlined. Further, the model is interpreted in light of some key institutional features characterising tax enforcement in OECD countries. Throughout the survey, findings...

This paper studies tax evasion in the form of under-reported wages in Ecuador using microdata from a combination of electronic billing and personal income tax returns filed in 2017. Bringing together this novel combination of data, the study applies the standard method Pissarides and Weber...

This paper develops a dynamic general equilibrium model where employers may avoid making social security contributions by offering some workers "secondary contracts". When calibrated using aggregate tax revenue data, the model delivers estimates of secondary "off the books" employment that are...

This article incorporates tax evasion into an optimum taxation framework with individuals differing in earning abilities and initial wealth. We find that despite the possibility of its evasion a tax on initial wealth should supplement the optimal nonlinear income tax, given a positive...
