We consider a model of a fishery in which the dynamic of the unharvested fish population is given by the stochastic logistic growth equation. Similar as in the classical deterministic analogon, we assume that the fishery harvests the fish population following a constant effort strategy. In a...

Fershtman and Nitzan (1991) presented a continuous dynamic public good game model and solved the model for feedback Nash-equilibria. Wirl (1996) extended the model and considered nonlinear strategies. Both models do not include uncertainty and hence neglect an important factor in the theory of...

We show that under the Black Scholes assumption the price of an arithmetic average Asian call option with fixed strike increases with the level of volatility. This statement is not trivial to prove and for other models in general wrong. In fact we demonstrate that in a simple binomial model no...

Pension schemes all over the world are under increasing pressure to efficiently hedge longevity risk imposed by aging populations. In this work, we study an optimal investment problem for a defined contribution pension scheme that decides to hedge longevity risk using a mortality-linked...
