It is common to summarize the impact of tax havens as a shift of tax revenues from high to low-tax jurisdictions. This chapter discusses the economic impact of tax havens that goes beyond a zero-sum transfer of the tax base, what we label real effects. We review the literature and focus on...

This paper provides empirical evidence on intertemporal income shifting during the implementation of a major tax reform in Uruguay. We exploit VAT and income tax returns for the universe of individuals that declare activity as liberal professionals (e.g. lawyers, public notaries, architects,...

We investigate multinational firms' activities in tax havens and regulatory efforts to curb these activities in three steps. First, we discuss the evolution of information exchange and disclosure regimes among tax authorities, with a focus on the recent Countryby-Country (CbC) reporting regimes,...

We use a global dataset with information on 210,000 corporations in 102 countries to investigate whether cross-border profit shifting by multinational firms is more prevalent in less developed countries. We propose a novel technique to study aggressive profit shifting and improve the credibility...

This paper examines the determinants and margins of profit shifting through transfer pricing. We develop a theory model, where transfer pricing patterns are governed by a generalized concealment cost function (CCF). Our empirical analysis draws on micro-level data about transaction-level...

We study the welfare and distribution effects of corporate taxation and transfer pricing in an asymmetric general oligopolistic equilibrium trade model. Without profit shifting, an increasing profit tax rate shifts welfare towards the taxing country, where it also decreases real wages, whereas...

Illicit financial flows (IFFs) constitute a major challenge for development in the Global South, as domestic resource mobilization is imperative for providing crucial public services. While several methods offer to measure the extent of IFFs, each has its benefits and drawbacks. Critically,...

The geography of corporate profit shifting is often presented in public discourse in simplistic and inaccurate terms. Not only can this easily mislead audiences, but it shapes political responses to the problem in such a way as to undermine the prospects for genuine progress. In this paper, we...

This paper proposes a model of optimal tax-induced transfer pricing with a fuzzy arm's length parameter. Fuzzy numbers provide a suitable structure for modelling the ambiguity that is intrinsic to the arm's length parameter. For the usual conditions regarding the anti-shifting mechanisms, the...
