In many countries entrepreneurship is promoted through tax reductions for small businesses and by various government support schemes. We analyze the effects of such policies to subsidize small businesses in a setting where both the risk-return characteristics of the selected innovation project...

We use a simple framework where firms in two countries serve their respective domestic markets and a world market to analyze under which conditions cost-reducing mergers will be beneficial for the merging firms, the home country, and the world as a whole. For a national merger, the policies...

An important puzzle in corporate taxation is that effective tax rates have fallen significantly while tax revenue has simultaneously risen in most countries. Moreover, the gross profitability of firms seems to be lower in high-tax countries, even though standard models of international...

We study the optimal combination of corporate tax rate and tax base in a model of a small open economy with heterogeneous firms. We show that it is optimal for the small country's government to effectively subsidize capital inputs by granting a tax allowance in excess of the true costs of...

The Global Minimum Tax (GMT) is applied only to firms above a certain size threshold, permitting countries to set differential tax rates for small and large firms. We analyse tax competition between a tax haven and a non-haven country for heterogeneous multinationals to evaluate the effects of...

Heterogeneous firm productivity raises the question of whether governments should pursue `pick-the-winner' strategies by subsidizing highly productive firms more, or taxing them less, than their less productive counterparts. We study this issue in a setting where governments can set...

Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, thus suggesting a ‘race to the top’ in capital standards. We study regulatory competition when banks are heterogeneous and give loans to firms that produce output...

By introducing controlled-foreign-company (CFC) rules, the parent country of a multinational firm reserves the right to tax the income of the firm’s foreign affiliates if the tax rate in the affiliate’s host country is below a specified threshold. We identify the conditions under which...

We offer a new explanation for why taxes have become less progressive in many countries in parallel with an increase in income inequality. When performance-based compensation differentials are needed to incentivize effort, redistribution through progressive income taxes becomes less precisely...
