Dynamic Effects of Permanent and Temporary Dividend Tax Policies on Corporate Investment and Financial Policies

We develop a neoclassical partial equilibrium model to analyze the dynamic effects of permanent and temporary dividend tax policies on corporate investment and financing decisions. Facing a tax system with corporate and personal income taxes, dividend tax and capital gains tax, a firm decides how much to invest and how to finance investment by equity or debt subject to collateral constraints and capital adjustment costs. We characterize steady state and simulate transitional dynamics following tax policy changes. We find the following novel results: First, both temporary and permanent dividend tax changes do not have long-run effects on a firm's capital formation, but have short-run effects on its investment and financial policies. Second, an anticipated temporary dividend tax cut has a short-run effect of lowering investment, similar to an anticipated permanent dividend tax increase. Third, a firm responds asymmetrically to an anticipated permanent dividend tax increase versus an anticipated permanent dividend tax cut due to the collateral constraint. Finally, in anticipation of future tax changes, the firm engages in tax arbitrage by borrowing or saving in order to transfer corporate earnings across time so as to reduce shareholder's tax burden
