The folk result in Kyle-Back models states that the value function of the insider remains unchanged when her admissible strategies are restricted to absolutely continuous ones. In this paper we show that, for a large class of pricing rules used in current literature, the value function of the insider can be finite when…

48 results for “pricing rules”
In this paper we use fuzzy systems theory to convert the technical trading rules commonly used by stock practitioners into excess demand functions which are then used to drive the price dynamics. The technical trading rules are recorded in natural languages where fuzzy words and vague expressions abound. In Part I of t…

Kyle (1985) builds a pioneering and influential model, in which an insider with long-lived private information submits an optimal order in each period given the market maker's pricing rule.

A simple model of price formationcond-mat.stat-mech
A simple Ising spin model which can describe the mechanism of price formation in financial markets is proposed.

Simple model of a limit order-driven marketcond-mat.stat-mech
We introduce and study a simple model of a limit order-driven market.
