The continuous-time version of Kyle's (1985) model is studied, in which market makers are not fiduciaries. They have some market power which they utilize to set the price to their advantage, resulting in positive expected profits. This has several implications for the equilibrium, the most important being that by setting a modest fee conditional of the order flow, the market maker is able to obtain a profit of the order of magnitude, and even better than, a perfectly informed insider. Our model…

Insider Trading with Non-Fiduciary Market Makers
The single auction equilibrium of Kyle's (1985) is studied, in which market makers are not fiduciaries. They have some market power which they utilize to set the price to their advantage, resulting
Strategic insider trading equilibrium: a filter theory approach
The continuous-time version of Kyle’s (Econometrica 53(6):1315–1336, 1985) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing
Insider Trading in Continuous Time
The continuous-time version of A. Kyle's (1985) model of asset pricing with asymmetric information is studied. It is shown that there is a unique equilibrium pricing rule within a certain class. This
Partially informed noise traders
The single auction equilibrium of Kyle’s (1985) is studied, in which noise traders may be partially informed, or alternatively they can be manipulated. Unlike Kyle’s assumption that the quantity
Long‐Lived Private Information and Imperfect Competition
The authors develop a multiperiod auction model in which multiple privately informed agents strategically exploit their long-lived information. They show that such traders compete aggressively and
On the Impossibility of Informationally Efficient Markets
If competitive equilibrium is defined as a situation in which prices are such that all arbitrage profits are eliminated, is it possible that a competitive economy always be in equilibrium? Clearly
An Anticipative Linear Filtering Equation
TLDR
This paper proves a Riccati type equation for a linear system where the (normally distributed) initial value X0 of the signal process Xt has a given correlation function with the noise (Brownian motion Bt) of the observation process Zt.
The generalized covariation process and Ito formula
New results on the innovations problem for non-linear filtering
Abstract : This report considers an observed stochastic process consisting of a signal with additive noise. It assumes that the signal has finite energy and that the signal and noise are independent.
