This paper examines the intraday behavior of market liquidity in an order-driven market. Along with previous studies, we show that the U-shaped intraday pattern of spread does not depend on the market architecture. We also find that bid-ask spread and market depth are two dimensions of market liquidity. Market liquidity is inversely related to price volatility. We also investigate the impacts o...

This paper describes the signaling that occurred in many of the FCC spectrum auctions. The FCC’s simultaneous ascending auctions allowed bidders to bid on numerous communication licenses simultaneously, with bidding remaining open on all licenses until no bidder was willing to raise the bid on any license. Simultaneous open bidding allowed bidders to send messages to their rivals, telling them ...

Our subject is foreign exchange auction through market makers. We consider market maker’s policy to choose bid and ask as an optimization problem. We show that if traders’ expectations are more heterogeneous, the market maker widens bid and ask spread. He can take advantage of the heterogeneous expectations. We derive an equation of expected transaction prices. This equation makes it possible t...

We propose an equilibrium model to study the impact of short-sale constraints on market prices and liquidity in imperfectly competitive markets where market makers have significant market power and are averse to inventory risk. We show that shortsale constraints decrease bid because of the market power and increase ask because of the risk aversion. Our model can therefore help explain why short...

in this research the asymmetric and non-linear correlation between the market returns and trading volume variables has modeled with the dcc-garch approach; and the impacts of market shocks, weekend and calendar effects on the market returns and trading volume are surveyed. the estimation results of parameters of the model by the maximum likelihood method show that previous day’s market return h...

In this paper capacity withholding in an oligopolistic electricity market that all Generation Companies (GenCos) bid in a Cournot model is analyzed and the capacity withheld index, the capacity distortion index and the price distortion index are obtained and formulated.
