We consider the effect of asymmetric information on price formation process in a financial market where private information is held by a market maker. A Byesian game is proposed in which there is price competition between two market makers with two different information partition.

This paper proposes a class of asymmetric Autoregressive Conditional Duration models, which extends the ACD model of Engle and Russell (1997). The asymmetry consists of letting the duration process depend on the state of the price process in the beginning and at the end of the each duration. If...

The asset market is incomplete. Fix-price equilibria exist. Price regulation Pareto improves on a competitive allocation. Prices in competitive markets may fail to attain equilibrium. The theory of general competitive equilibrium does not account for the adjustment of prices; empirical evidence...

In this paper, we focus on the trade and quote data for the IBM stock traded at the NYSE. We present two different framworks for analyzing this dataset. First, using regularly sampled observations, we characterize the intraday volatility of the mid-point of the bid-ask quotes by estimating GARCH...

In this paper we exploit global analysis to explore welfare properties of a standard one-commodity GEI, under different notions of constrained Pareto optimality. In a unifying framework we revise and extend some of the leading results of the literature on incomplete markets and government...

As one important form of market circuit breakers, price limits have been often imposed in stock and future mnarkets. This paper considers modelling the return process of such assets, focusing on the treatment of price limits. As a result, a censored-GARCH model is formulated and a Bayesian...

We show in this paper how, in a model of assets exchange in complete competitive markets, heterogeneity of the agent's subjective probabilities generates aggregate expenditures for Arrow-Debreu securities that have the gross substitutability property, with the consequences that competitive...
