Abstract: | This article shows how an asymmetric information dynamic model of market-maker behavior can be empirically estimated, and demonstrates how the information in trade data can be extracted and analyzed. The article models the price-setting problem facing one agent and determines using trade data the underlying parameters of that agent's optimal policies. The model has two prior parameters: the market-maker's probability that an information event occurs overnight and the prior probability that an information event is good news , given that it occurs. |
