The well-known Johansson-Samuelson theorem proves that, in partial equilibrium, comprehensive income taxation with a uniform tax rate does not affect asset values if tax depreciation allowances coincide with economic depreciation. In this article, we show that this result fails to hold in...

We analyze Auerbach´s (1991) proposal of a retrospective capital gains tax, which is equivalent to an accrual tax on an ex ante basis. Using a continuous-time model with stochastic interest rates and serially correlated asset returns, we prove that such an equivalence still holds. This means...

We study the optimal consumption and portfolio for an agent maximizing the expected utility of his intertemporal consumption in a financial market with: (i) a riskless asset, (ii) a stock, (iii) a bond as a derivative on the stochastic interest rate, and (iv) a longevity bond whose coupons are...

We study optimal dynamic compliance decisions in an uncertain environment. Contrary to the static literature, greater uncertainty affects consumption, not the optimal tax evasion rule. Thus, audit and sanctions rather than fiscal uncertainty should be used to control tax evasion.
