Recent research has proposed several ways in which overconfident traders can persist in competition with rational traders. This paper offers an additional reason: overconfident traders do better than purely rational traders at exploiting mispricing caused by liquidity or noise traders. We...

This paper builds an evolutionary model of an industry where firms produce differentiated products. Firms have different average cost functions and different demand functions. Firms are assumed to be totally irrational in the sense that firms enter the industry regardless of the existence of...

This paper shows that a monopolistically competitive equilibrium can evolve without purposive profit maximization. Specifically, this paper formulates a precise evolutionary dynamic model of an industry where there is continuous entry of firms that randomly select their output levels on entry...

While the literature usually justifies informational efficiency in the context of rationality, this article shows informational efficiency by applying the evolutionary idea of natural selection. In a dynamic futures market, speculators are assumed to merely act upon their predetermined trading...

This paper develops a simple signaling model whereby high valuation firm uses levels of investment, debt and dividends to convey information to the market regarding its valuation. Conditions are determined under which investment, debt and dividends are employed in a separating Nash equilibrium....

Profit maximization is the usual prerequisite for achievement of a perfectly competitive equilibrium. However, for a long time it has been thought that this principle of profit maximization can be replaced by natural selection. This paper shows analytically that with the market selection...

This paper uses an evolutionary approach to explain the origin of money as media of exchange in a primitive economy, where agents specialize in production for the purpose of trading for their own consumption goods. A general class of dynamics, which is consistent with Darwinian dynamics, is...

This article begins by proposing a random taste parameterization of a quadratic extension of the PIGLOG demand system at the household level, which is consistent with exact aggregation. This variation in tastes is a random function of household characteristics. The econometric implication is...

This paper builds an evolutionary model of an industry where firms produce differentiated products. Firms have different average cost functions and different demand functions. Firms are assumed to be totally irrational in the sense that firms enter the industry regardless of the existence of...
