Tax administrations use machine learning to predict risk scores as a basis for selecting individual taxpayers for audit. Audits detect noncompliance immediately, but may also alter future filing behavior. This analysis is the first to estimate compliance effects of audits among high-risk wage...

The Norwegian Tax Administration operated multi-year random audits of personal income tax returns. We exploit this exceptional randomized setup to estimate the effects of tax audits on future compliance explicitly distinguishing between dynamic responses of compliant and noncompliant audited...

This paper considers the welfare implications of a tax on real estate transfers. A theoretical analysis shows how the discouragement of mutually beneficial transactions as well as tax-sheltering activities give rise to a welfare loss that can be estimated comprehensively from the empirical...

This paper, originally designed to focus on discovering a suitable tax structure that befits an aspiring LMIE as it advances toward the UMIE status. On reflection, it becomes evident that it is hard to meaningfully deliberate on the composition of taxes without focussing in equal measure on the...

In a centralized federation, where tax rates and taxation rules are set by the federal government, manipulating the thoroughness of tax auditing and the effectiveness of tax collection could be attractive for regional authorities because of a variety of reasons. These range from tax competition...

In a market where firms with different characteristics decide upon both the level of emissions and their reports, we study the optimal audit policy for an enforcement agency whose objective is to minimize the level of emissions. We show that it is optimal to devote the resources primarily to the...

Previous literature shows that income taxation significantly affects the behavior of high-income earners and business owners. However, it is still unclear how much of the response is due to changes in effort and other real economic activity, and how much is caused by tax avoidance and tax...

This paper estimates the size and macroeconomic effects of base erosion and profit shifting (BEPS) using a computable general equilibrium model designed for corporate taxation and multinationals. Our central estimate of the impact of BEPS on corporate tax losses for the EU amounts to €36...

Several African countries have to increase their tax revenues to finance human and economic development. General consumption taxes, such as VATs, are the preferred instrument for doing so, because they are less detrimental to growth than income taxes. To enable their use, VAT design has to be...
