Distributive Justice in International Tax Law

Johanna Stark

Recent times have seen growing calls for considerations of justice to be given a greater role in international tax law. The main driver of these calls are distributive concerns, although agreement is still missing as to what this means in terms of both principle and practice. This article asks whether it is the task of international tax law to implement principles of distributive justice beyond the national context and gives an overview of how the ‘global justice debate’ in contemporary moral and political philosophy bears on this question.

Regulatory Thickets – a Problem?

Stefano Barbieri, Kai A. Konrad

The growing thicket of regulatory rules in professional and private life is a well-known phenomenon in modern societies. Whereas specific rules and regulations may seem sensible, an excess of too strict and too deep regulations often creates problems, to the detriment of sensibility. Quite apart from issues of free personal development, this excess can curb the ability to innovate and inhibit the dynamics of growth, and thus undermine the foundations for societal welfare.

Influencer Income and Tax Treaties

Savvas Kostikidis

When influencers post clips and snapshots from their lives on TikTok or Instagram, they are often marketing not only themselves, but also a product suitable for the occasion. As well as cash, they often receive non-cash benefits. They sell the rights to their photos or their name, some have their own merchandise. And they are often active – and liable to pay taxes – internationally. Savvas Kostikidis reveals why this can get complicated and considers the categorisation of the income earned by influencers in relation to tax treaties.

Preemption Contests Between Groups

Stefano Barbieri, Kai A. Konrad, David Malueg

In conflicts that occur simultaneously within and between groups, who would, when and why put aside their own interest to stand up for the interest of the social group he or she belongs to? Recent findings from game theoretical research allow a better understanding of such situations and could help speed up the resolution of conflicts.

Die neue Weltsteuerordnung: Politische Eile oder konzeptionelle Weile?

Wolfgang Schön

Die Diskussion um eine angemessene Besteuerung von Google, Apple, Facebook und Amazon ist in eine Debatte um die weltweite Neuordnung der Besteuerungsrechte zwischen den Staaten gemündet. Doch müssen die konzeptionellen Grundlagen der „neuen Weltsteuerordnung“, erarbeitet unter Federführung der OECD, gründlicher durchdacht werden. Wir sollten uns die Zeit dafür nehmen. Denn damit wird ein Systemwechsel eingeläutet, dessen strukturelle Folgen auf mittlere und lange Frist die gesamte Weltwirtschaft betreffen könnten.
