Using the universe of South African corporate tax returns for 2009-14, we estimate profit- and debt-shifting responses in South Africa. We find evidence that South African subsidiaries engage in profit shifting and that profit-shifting responses to tax incentives across all channels are...

This paper provides the first direct systematic evidence of profit shifting through transfer mispricing in a developing country. Using South African transaction-level customs data, I directly test for transfer price deviations from arm's-length pricing. I find that multinational firms in South...

Globally, the largest 0.001 per cent of firms earn roughly one-third of all corporate profits. Nonetheless, there is little understanding of how profit shifting differs across firm size. Using South African corporate tax returns from 2010-14, we investigate the link between firm size and profit...

This paper studies how the global minimum tax shapes national tax policies and welfare in a formal model of international tax competition with heterogeneous countries. The net welfare effect is generally ambiguous from the perspective of non-havens. On the one hand, the global minimum tax raises...

Corporate profit shifting to tax havens negatively impacts corporate tax revenue, particularly in low-income countries. Two studies published in 2016 and 2018 have proven this correlation using data from 2013. In this paper, I use the most recent version of the UNU-WIDER Government Revenue...

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...

The Global Minimum Tax (GMT) is applied only to firms above a certain size threshold, permitting countries to set differential tax rates for small and large firms. We analyse tax competition between a tax haven and a non-haven country for heterogeneous multinationals to evaluate the effects of...

Uganda has one of the lowest corporate income tax collection rates in sub-Saharan Africa, while offering generous corporate tax incentives. It is unclear whether tax incentives achieve their objectives without primarily benefiting firms, potentially undermining domestic revenue mobilization and...

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,...

Illicit financial flows directly impact a country's ability to raise, retain, and mobilize its own resources to finance sustainable development. Against a backdrop of a weak public financial position attributed to capital flight, tax avoidance, and dependence on corporate income taxes,...
