Abstract: | In this paper we question the idea that the deduction of debt interest is always an effective policy instrument to spur firm investment. We analyse the investment decision in presence of a borrowing constraint on the amount of debt that the firm can raise. We show that if the debt interest rate is decreasing in the firm's capital accumulation and another financial resource more expensive than debt is available (at least for levels of debt lower than the upper bound), then the deduction of the debt interest from taxes on capital income may reduce firm investment. This theoretical result is relevant for economic policy decisions when financial intermediaries are not willing to finance beyond a certain threshold but firms have access to other sources of finance. |
