This study provides a comprehensive analysis of various aspects of R&D tax incentives. It explains the economic justification behind the state support of research and development and summarizes its main types. In addition, it gives an overview of the existing R&D tax incentives in Europe and provides a thorough review of the empirical literature on the outcomes of fiscal incentives. Furthermore, the Devereux and Griffith model is used to determine the effective tax burden of multinational firms that reside in countries which implement R&D tax support and countries which do not. The model is developed further following Spengel and Elschner (2010) and Evers et al. (2015) to reflect a potential use of R&D tax incentives by multinational firms for tax planning. The hypothesis developed in the model is tested in an empirical estimation, where we employ the OECD data on international co-operation in patents. According to our main findings, there are at least two reasons why input-oriented R&D tax incentives, such as tax credits and tax super-deductions, constitute a more suitable instrument for fostering research and development than the output-oriented incentives, such as IP Boxes. First, there is robust evidence found in the empirical literature which shows the positive effect introducing inputoriented tax incentives has on a firm's innovative activity, whereas studies on output-oriented tax incentives are not able to support this argument. Secondly, according to our theoretical and empirical analyses, output-oriented R&D tax incentives may be used by multinationals for tax planning as opposed to their intended use of fostering research and development.

IntroductionState support of research and development (R&D) is not only economically justified in numerous theoretical and empirical studies but is also enforced in many countries around the world. Fiscal incentives constitute one of the key instruments of state support of R&D, as they are easier to implement and are less complex to monitor than, for example, direct R&D grants or subsidies. There are various types of fiscal incentives for research and development, some of which focus on supporting the development or input phase of a research process, whereas others concentrate on the income-generating output phase. The first group of R&D tax incentives includes tax c...
