International corporate tax avoidance by multinational enterprises likely lowers the Czech Republic's corporate income tax revenue, but it is not clear by how much. To clarify this I first review existing estimates of the costs of international corporate tax avoidance to government revenue...

We formulate a bivariate stochastic volatility jump-diffusion model with correlated jumps and volatilities. An MCMC Metropolis-Hastings sampling algorithm is proposed to estimate the model's parameters and latent state variables (jumps and stochastic volatilities) given observed returns. The...

Illicit financial flows (IFFs) threaten countries' ability to achieve the Sustainable Development Goals (SDGs). Progressing on the IFFs target is thus crucial, as is the ability to measure achieved progress. In this paper we explore how to best statistically measure tax avoidance by...

The geography of corporate profit shifting is often presented in public discourse in simplistic and inaccurate terms. Not only can this easily mislead audiences, but it shapes political responses to the problem in such a way as to undermine the prospects for genuine progress. In this paper, we...

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...

Private Country-by-Country Reporting (CbCR) is a measure against tax avoidance by large multinationals, implemented throughout the EU in 2016. Multinational companies with an annual revenue over € 750 million have been required to report their global activities on a country-by-country basis to...

This paper estimates income tax underreporting for the case of Germany, by income category and along the income distribution. Comparing weighted samples of survey and tax data, we find patterns that are in line with the literature: Average income from self-employment and from rent and lease in...

By exploiting country-by-country reports (CBCRs) prepared according to the OECD BEPS Action 13's minimum standards and voluntarily published by multinational corporations (MNCs), we show that the CBCR data can be used to identify how much MNCs pay in taxes and where, as well as how important tax...

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...

In this paper we use the recently developed Bilateral Financial Secrecy Index to evaluate which countries supply most secrecy to EU Member States. Then, we assess how well-aimed are two of the EU's recent policy efforts to increase financial transparency: automatic Country-by-Country Reporting...
