Improving tax collection is essential if developing economies are to avoid over-reliance on external donor funds and loans. Revenue authorities in the Global South have recently adopted new policy tools to improve domestic revenue mobilization through taxes. One such new policy is a withholding...

We develop a framework to conduct experiments for estimating direct and spillover effects when units are grouped into mutually exclusive clusters. Crucially, our framework accounts for heterogeneous treatment effects across clusters and heterogeneous cluster sizes, which are pervasive in...

We report results from a large-scale, pre-registered randomized field experiment in 159 Norwegian schools over four years. The intervention includes students aged 7-9 and consists of pulling students from their regular mathematics classes into small, homogenous groups for mathematics instruction...

This paper describes a number of strategies that experimenters may use to improve the external validity of their own findings, and of their research field as a whole. The paper emphasizes a dynamic view of research processes, in which learning about treatment and treatment adoption does not...

We use income survey data linked with tax records at the individual level for Estonia to estimate the determinants and extent of income tax compliance in a novel way. Unlike earlier studies attributing income discrepancies between such data sources either to tax evasion or survey measurement...

We estimate the extent of income underreporting among working households, using data from an income survey linked with individual tax records for Estonia. Income underreporting is inferred from consumption propensities, following and extending the method by Pissarides andWeber (1989). Our...

This paper is analyzing tax morale in three selected European countries through the evaluation of the results of the European Values Study. The main aim is to identify the factors that influence taxpayers' decisions on the issue of whether they justify cheating on tax or not. The dependence and...

We study the impact of the media negativity bias on tax compliance. Through a framed laboratory experiment, we assess how the exposure to biased news about government action affects compliance in a repeated taxation game. Subjects treated with positive news are significantly more compliant than...
