This paper analyses the development of the ratio of corporate taxes to wage taxes using a simple political economy model with internationally mobile and immobile firms. Among other results, our model predicts that countries reduce their corporate tax rate, relative to the wage tax, either when...

This paper discusses tax policy measures to reduce corporate tax avoidance by extending taxation in the source country without imposing double taxation. We focus on four options: Bilaterally restricting interest and royalty deductibility, introducing an inverted tax credit system, levying...

A growing body of economics literature shows that multinational corporations (MNCs) shift their profits to tax havens. We contribute to this evidence by comparing a range of available data sets focusing on US MNCs, including country-by-country reporting data which has been released in December...

This paper evaluates the Common Consolidated Corporate Tax Base (CCCTB) recently proposed by the European Commission. We find that if the CCCTB is introduced as it is currently proposed (including loss consolidation), then it is likely to impose large tax revenue costs of about one fifth of the...

The increasing use of intellectual property as a means to shift profits to low-tax jurisdictions or jurisdictions with so-called "patent boxes" is a major challenge for the corporate tax base of medium- and high-tax countries. Extending a standard tax competition model for capital-enhancing...

This paper analyses capital tax competition between jurisdictions of different size when multinational firms can shift some fraction of their tax base between them. For the case of revenue maximizing governments, we show that introducing profit shifting will not generally increase downward...

This paper simulates the impact of the global minimum corporate tax rate (GMCTR) in Uganda by estimating the difference between the mechanical and the behavioural changes in tax revenue. Overall, implementation of GMCTR will increase tax revenue, and the revenue increase is inversely...

In its 2015 Final Report on “Measuring and Monitoring BEPS, Action 11”, the OECD introduced six indicators to quantify and evaluate base erosion and profit shifting (BEPS) activity over time. In this study, we revisit three selected indicators, provide a numerical update for recent periods...

According to plans put forward by the OECD/G20 Inclusive Framework on BEPS, a share of residual profit earned by eligible MNEs is to be taxed by market jurisdictions. For this purpose, revenue-based formulaic apportionment of residual profit is proposed. This note argues against the use of a...
