Qualitative case studies suggest that the outcomes of tax treaty negotiations are determined by power politics and negotiating capability. In contrast, quantitative studies have tended to depart from a model that implies absolute gains, full rationality, and perfect information on the part of...

The failure of the Somali state from 1993 to 2012 represents one of the world's most profound and prolonged cases of state collapse. Initially, education and other government services came to a standstill. With the halt of fighting in some areas, local communities with the support of the United...

This paper frames the transition towards clean energies as a sequential process of instrument choice and instrument change. First, regulators decide how to initiate the transition away from fossil energies. Here, support policies for renewable electricity are politically convenient because they...

In this paper we study the effects of various tax schedule discontinuities on the behavior of small firms using high-quality and population-wide tax register data from South Africa. We use the bunching method to analyse how these discontinuities affect the firm-size distribution. We first...

This paper proposes to understand a singular but salient factor that enables the wealthy to deflect their tax burden downwards: elites' political leverage to shape legislation via their capacity to influence political actors and policy outcomes. The analysis sheds light on alternative mechanisms...

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...

We present new evidence on the effects of South Africa's Employment Tax Incentive (ETI), a hiring and employment wage subsidy aimed at reducing youth unemployment. We show that attempts to estimate firm-level treatment effects via conditional difference-in-differences are likely to fail when...
