Tax certainty aims at the stabilization of expectations of both, taxpayers and governments. Improving tax payer service, easing cooperation channels and clarifying legal framework are strategies already in place to increase tax certainty, even though to different extent depending on the...

This paper explores the effects of tax provisions aimed at restricting multinationals' tax planning on foreign direct investment (FDI). Using a unique dataset which allows us to observe the worldwide activities of a large panel of multinational firms, we test how limitations of interest tax...

This paper highlights the importance of different investment motives and to what extend they affect the responsiveness to corporate taxation. In particular, we discuss how to classify investment as non-related, horizontal, vertical and complex types using a combination of both firm-specific...

This paper synthesizes and extends the literature on the taxation of foreign source income in a framework that covers both greenfield and acquisition investment, and a general constraint linking investment at home and abroad for the multinational by introducing a cost of adjustment for the...
