The proliferation of algorithmic high-frequency trading in financial markets has also led to an increase in new types of fraudulent activity. Since the flash-crash of 2010 first brought it to popular prominence, layering or spoofing fraud has become a major concern for financial regulators...

Empirical equilibrium search models have attracted a growing interest in recent years. Estimation of such models has not been completely successful, however. This has led researchers to develop more sophisticated versions of the models, in an attempt to get a better fit to the data. This study...

This paper investigates the possibility that wealth (holdings of money) serves as a signal of ability to produce high quality products for agents who cannot directly observe the quality of the products. A producer’s wealth may advertise past success in selling products to agents who knew the...

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. -- Search ; Matching ;...

In this paper we are studying a multiple player two-armed bandit model with two risky arms in discrete time. Players have to find the superior arm and can learn from others' history of choices and successes. In equilibrium, there is no con?ict between individual and social rationality. If agents...

This paper provides a search theoretic model with endogenous job creation, and homogenous workers and firms. The model introduces bidding costs and allows the current employer to make a counteroffer with probability q when the worker receives an outside offer. In equilibrium, a higher level of...

In a two-sided search market agents are paired to bargain over a unit surplus. The matching market serves as an endogenous outside option for a bargaining agent. Behavioral agents are commitment types that demand a constant portion of the surplus. The frequency of behavioral types is determined...

This paper shows that all perfect Bayesian equilibria of a dynamic matching game with two-sided incomplete information of independent private values variety are asymptotically Walrasian. Buyers purchase a bundle of heterogeneous, indivisible goods and sellers own one unit of an indivisible good....

This paper considers a frictional market where buyers and sellers, with unit demand and supply, search for trading opportunities. The analysis focuses on explicit search frictions, allows for two-sided incomplete information, and puts no restriction on agent heterogeneity. In this context, a...

In this paper, we present a directed search model of the housing market. The pricing mechanism we analyze reflects the way houses are bought and sold in the United States. Our model is consistent with the observation that houses are sometimes sold above, sometimes below and sometimes at the...
