Shorting in Speculative Markets
We propose a continuous-time model of trading with heterogeneous beliefs. Risk-neutral agents face quadratic costs-of-carry on positions and thus their marginal valuation of the asset decreases with the size of their position, as it would be the case for risk-averse agents. In the equilibrium models of heterogeneous beliefs that followed the work by Harrison and Kreps, investors are risk-neutra...
متن کاملSupply and Shorting in Speculative Markets
We propose a continuous-time model of trading among risk-neutral agents with heterogeneous beliefs. Agents face quadratic costs-of-carry on their positions and as a consequence, their marginal valuation of the asset decreases when the magnitude of their position increases, as it would be the case for risk-averse agents. In the equilibrium models of investors with heterogeneous beliefs that foll...
متن کاملA Theory of Disclosure in Speculative Markets
This paper presents a theory of disclosure in a market where investors have heterogeneous beliefs and face short-sale constraints. Assets trade above fundamentals reflecting the value of the option to sell to more optimistic investors in the future. The initial seller has an incentive to commit to an imprecise disclosure policy, despite the negative effect this has on the fundamental value of t...
متن کاملSpeculative bubbles in agricultural commodity markets
Numerous factors have been proposed in the literature as explaining the recent commodity price movements. In this paper we focus on one of the most widely discussed factors, the impact of speculative bubbles. We investigate whether commodity prices during the spike of 2007–2008 might have deviated from their intrinsic values based on market fundamentals. To do this, we use a bootstrap methodolo...
متن کاملConstructing Speculative Demand Functions in Equilibrium Markets
In computational markets utilizing algorithms that establish a general equilibrium, competitive behavior is usually assumed: each agent makes its demand (supply) decisions so as to maximize its utility (profit) assuming that it has no impact on market prices. However, there is a potential gain from strategic behavior via speculating about others because an agent does affect the market prices, w...
