When Promoters Like Scalpers AgEcon
Karp, Larry S.; Perloff, Jeffrey M..
If a monopoly supplies a perishable good, such as tickets to a performance, and is unable to price discriminate within a period, the monopoly may benefit from the potential entry of resellers. If the monopoly attempts to intertemporally price discriminate, the equilibrium in the game among buyers is indeterminate when the resellers are not allowed to enter, and the monopoly's problem is not well defined. An arbitrarily small amount of heterogeneity of information among the buyers leads to a unique equilibrium. We show how the potential entry of resellers alters this equilibrium.

MARKET-MAKING BEHAVIOR IN FUTURES MARKETS AgEcon
Liu, Holly; Williams, Jeffrey C.; Jorda, Oscar.
This paper examines voluntary market-making behavior, namely scalping, in futures markets. Specifically, this paper studies what factors determine scalpers' entry and exit, and how scalping affects market liquidity and price volatility. The data used for the analysis are time-stamped electronic transaction data marked with traders' identities from the Dalian Futures Exchanges in China. The contributions of this paper are: (1) to give detailed analysis of scalping behavior and its impact on market liquidity; (2) to develop new econometric tools for analyzing time-series count data; (3) to propose a new measure of liquidity.
Tipo: Conference Paper or Presentation Palavras-chave: Liquidity; Market-Making; Futures Markets; Scalpers; Autoregressive Conditional Intensity (ACI); Volatility; Marketing.
