How much companies pay in corporate income taxes is often better captured by effective tax rates (ETRs) rather than by statutory ones. Economists further distinguish between those modelled using the law - forward-looking ETRs - and those estimated from actual data on companies' profits and taxes...

11 European countries now operate IP Box regimes that provide substantially reduced rates of corporate tax for income derived from important forms of intellectual property. We incorporate these policies into forward-looking measures of the cost of capital, effective marginal tax rates and...

The paper presents an econometric accounting of the effective corporate tax rate in Australia for the years 1993 to 1996. The estimation is a panel of Australian firms that uses a specially gathered financial data base. Using fixed and random effects, the model specifies that the statutory tax...

R&D tax incentives have become a widely used policy tool to promote business R&D. How do they shape firms’ incentives to invest in R&D? This paper contributes a methodology to construct forward-looking effective tax rates for an R&D investment that reflect the value of expenditure-based R&D...

Effective tax rates (ETRs) estimated from the balance sheet data of multinational corporations (MNCs) are useful for comparing MNCs' corporate income taxation across countries. In this paper we propose a new methodological approach to estimate ETRs as reliably and as for as many countries as...

We develop a new methodology to decompose the observed decline in multinational corporations' (MNCs') effective tax rates into profit shifting to tax havens and several other components. We apply this methodology to the best available data for MNCs headquartered in the US - from the Bureau of...

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...
