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...

In a recent article Davidson, Lawrence and Wilson propose a model showing that, in the presence of distortionary taxations and goods of different quality, tax evasion can be an optimal device. Here, we show that this result, although quite interesting, cannot be generalised to a framework where...

A longevity bond pays coupons which are proportional to the survival rate of a given population. In such a way the longevity risk becomes hedgeable on the financial market. In our model there are: (i) a longevity bond as a derivative on the population survival rate, (ii) a bond as a derivative...

The well-know Johansson-Samuelson Theorem proves that, in partial equilibrium, comprehensive income taxation with a uniform tax rate is neutral in terms of investment decisions, if fiscal depreciation allowances coincide with economic depreciation. In this article we show that this result does...

In this article, 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, we prove that equivalence holds even if the risk-free asset return is correlated...

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.

The reforms that have reshaped the public health care systems have often been coupled with devolution. However, this process has frequently been accompanied by widespread soft budget constraint policies. In this paper we argue that the soft budget constraint arises from a cooperative game...
