Longer patents to small inventors may accelerate genetic research with distant payoffs by assuaging their fears that a large, low-cost rival would quickly appropriate profits. [JEL H41, D45]

Tax rates have fluctuated considerably since federal income taxes were introduced in the U.S. in 1913. This paper analyzes the effects of stochastic taxation on asset prices in a dynamic general equilibrium model. Stochastic taxation affects the after-tax returns of both risky and safe assets. Whenever taxes change, bond and equity prices adjust to clear the asset markets. These price adjustmen...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework where (voluntary) nonparticipation and (involuntary) unemployment are endogenous. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the global response of the employment rate, which depends not only on the participation (labor supply) respon...

This paper analyzes asymmetric tax competition under formula apportionment. It sets up a model with multinationals where two welfare-maximizing jurisdictions of different size levy source-based corporate taxes and allocate taxes using the formula approach. At the Nash equilibrium, tax rates are too low and public goods quantities are to small. The paper shows that the larger country levies a la...

This paper surveys the econometric evidence on the effectiveness of fiscal incentives for R&D. We describe the effects of tax systems in OECD countries on the user cost of R&D — the current position, changes over time and across different firms in different countries. We describe and criticize the methodologies used to evaluate the effect of the tax system on Ž . R&D behaviour and the results f...

What Shapes Attitudes Toward Paying Taxes? Evidence from Multicultural European Countries Considerable evidence suggests that enforcement efforts cannot fully explain the high degree of tax compliance. To resolve this puzzle of tax compliance several researchers have argued that citizens’ attitudes toward paying taxes defined as tax morale helps to explain the high degree of tax compliance. How...

In this note, we introduce increasing returns to Bovenberg and Mooij’s (1994) model as generalised in Fullerton (1997) and use an example to show that (1) even with a distortionary labor tax, the optimal environmental levy is greater than the Pigouvian rate; (2) the difference between tax on the “dirty” good and the “clean” good is also greater than the Pigouvian tax; (3) under certain circumst...

Donald Trump’s election was a significant surprise. The reaction of company stock prices to the election reflects shifts in investor expectations about economic growth, taxes, and trade policy. High-beta stocks outperformed, presumably due to strengthened growth expectations. Expectations of significant corporate tax cuts boosted high-tax firms, but hurt firms with significant net operating los...

When multinational firms expand their operations in tax havens, do they divert activity from non-havens? Much of the debate on tax competition presumes that the answer to this question is yes. This paper offers a model for examining the relationship between activity in havens and non-havens, and discusses the implications of recent evidence in light of that model. Properly interpreted, the evid...

In markets where transactions are governed by contractual incompleteness, revealed intentions to evade taxes may affect market performance. We experimentally examine the impact of tax evasion attempts on the performance of credence goods markets, where contractual incompleteness results from asymmetric information on the welfare maximizing quality of the good. We find that tax evasion attempts ...
