The impact of tax and infrastructure competition on the profitability of local firms

International capital mobility intensifies tax competition between jurisdictions. However, many firms only operate domestically and are internationally immobile. This paper aims to analyze the effect of tax competition on the profitability of local (immobile) firms, especially when tax and non-tax instruments, including infrastructure provision, are involved. We show that tax competition decreases investment and profit of local firms when internationally mobile firms do not benefit sufficiently from local infrastructure.
