Modern portfolio theory regards the return of an asset as its upside, while volatility is seen as its downside. This view is shared by the majority of investors who dislike volatile markets. Recent results in financial mathematics, however, show that volatility is actually good, rather than bad,...

The paper examines a dynamic model of a financial market with endogenous asset prices determined by short run equilibrium of supply and demand. Assets pay dividends that are partially consumed and partially reinvested. The traders use fixed-mix investment strategies (portfolio rules),...

This paper deals with the deterministic and stochastic versions of the von Neumann-Gale model. Von Neumann's (1937) original concern was to determine a balanced path growing at a maximal rate for a linear and stationary technology and a price system supporting that path.Such a pair (a path and a...

In this paper we analyze the long-run dynamics of the market selection process among simple trading strategies in an incomplete asset market with endogenous prices. We identify a unique surviving financial trading strategy. Investors following this strategy asymptotically gather total market...

The paper analyzes the process of market selection of investment strategies in an incomplete asset market. The pay offs of the assets depend on random factors described in terms of a discrete-time Markov process. Market participants make dynamic investment decisions based on their observations...

This paper shows that a stock market is evolutionary stable if and only if stocks are evaluated by expected relative dividends. Any other market can be invaded by portfolio rules that will gain market wealth and hence change the valuation. In the model the valuation of assets is given by the...
