In this paper we apply a real-option model to study the effects of tax rate uncertainty on a firm's decisions. In doing so, we depart from the relevant literature, which focuses on fully equity-financed investment project. By letting a representative firm borrow optimally, we show that debt...

This article studies the effects of corporate tax asymmetries on irreversible investment. We discuss an asymmetric tax scheme where the tax base is given by the firm's return, net of an imputation rate. When the firm's return is less than this rate, however, no tax refunds are allowed. Contrary...

In this article we focus on a representative firm that can decide when to invest under default risk. On the one hand, this firm can benefit from generous tax depreciation allowances, on the other hand it faces a default risk. Our aim is to study the effects of tax depreciation allowances in a...

In this article we study the corporate tax effects on credit market equilibria. In particular, we develop a model that accounts for five pieces of evidence: i) the existence of a tax incentive to borrow, ii) the negative relationship between leverage and profitability, iii) the existence of...

We analyse tax competition with corporate income taxes in a common market where tax revenues are allocated according to an apportionment formula. Generally, tax competition is sharper (i.e., equilibrium tax rates are lower) the more tax-elastic is the apportionment formula. This depends on the...

This paper studies the market and welfare effects of two main tax reforms - the Corporate Business Income Tax (CBIT) and the Allowance for Corporate Equity tax (ACE). Using an imperfect-competition model for a small open economy, it is shown that the well-known neutrality property of ACE does...

In this article we use contingent-claim analysis to calculate the effective tax rate (ETR) under corporate debt finance. In particular, we deal with both pure debt and two of the most well-known hybrid securities, i.e., convertible, and reverse convertible bonds. We show that: 1) effective...

This article compares an ACE system with a CBIT system in an open economy. Using a realoption approach we show that, if a firm can decide when to invest, a tradeoff is found. According to traditional wisdom, a high-income firm investing in an ACE system faces a heavier tax burden at each...

This article discusses the effects of an asymmetric tax scheme on incremental and sequential investment strategies. The tax base is equal to the firm s return, net of an imputation rate. When the firm s return is less than this rate, however, no tax refunds are allowed. This scheme is neutral...

This article discusses the effects of taxation on the discrete choice of alternative projects. In particular, it is shown that if taxation affects the optimal timing of irreversible investment, then the discrete choice is distorted as well. This result has both methodological and political...
