Excise duties are an important source of government revenue and their rates change relatively often in the Czech Republic. Reforms of excise duties change the prices of goods, a change to which households respond by adjusting their expenditures. I use detailed Czech Statistical Office data and...

The rates of value added tax (VAT) have recently changed in the Czech Republic, and I simulate the impact of these reforms. They are an example of changes in indirect taxes that change the prices of goods and services, to which households can respond by adjusting their expenditures. I first...

Profit shifting of multinational corporations (MNCs) negatively affects citizens, governments as well as other companies in the European Union. This consensus seems to be emerging in spite of the fact that the phenomenon of profit shifting is unobservable directly and therefore only indirect and...

How much companies pay in corporate income taxes is often better captured by effective tax rates (ETRs) rather than by statutory ones.

The recent US tax reform, Tax Cuts and Jobs Act of 2017, lowered the statutory corporate income tax rates and brought other important changes for the taxation of multinational enterprises worldwide. This paper reviews these changes and discusses their effects for effective tax rates and tax...

We develop a methodology to decompose the tax revenue impact of the global minimum tax introduced in 2024 into several components and quantify its potential impact on profit shifting. We apply it to 34 thousand multinational-country observations from tax returns, financial statements and...
