This paper derives necessary and sufficient conditions for the existence of linear equilibria in the Rochet-Vila model of market making. In contrast to most previous work on the existence of linear equilibria in models of market making, we do not impose independence of the underlying random...

Most of the literature that studies frictional search-and-matching models with heterogeneous agents and random search investigates steady-state equilibria. Steady-state equilibrium requires, in particular, that the flows of agents into and out of the population of unmatched agents balance. We...

Steady state equilibria in heterogeneous agent matching models with search frictions have been shown to exist in Shimer and Smith (2000} under the assumption of a quadratic search technology. We extend their analysis to the commonly investigated linear search technology

The existence of a linear equilibrium in Kyle's model of market making with multiple, symmetrically informed strategic traders is implied for any number of strategic traders if the joint distribution of the underlying exogenous random variables is elliptical. The reverse implication has been...

We consider Kyle's market order model of insider trading with multiple informed traders and show: if a linear equilibrium exists for two different numbers of informed traders, asset payoff and noise trading are independent and have finite second moments, then these random variables are normally...
