Bid and ask sizes at the top of the order book provide information on short-term price moves. Drawing from classical descriptions of the order book in terms of queues and order-arrival rates (Smith et al., 2003), we consider a diffusion model for the evolution of the best bid/ask queues. We compute the probability that the next price move is upward, conditional on the best bid/ask sizes, the hi...

Time changes of return, inefficiency studies performed and presence of effective factors on share return rate are caused development modern and intelligent methods in estimation and evaluation of share return in stock companies. Aim of this research is prediction of return using financial variables with artificial neural network approach. Therefore, the statistical population of this study incl...

This paper describes an agent-based model of financial markets with monopolistic or competitive market-makers and analyzes some of the emergent properties of these markets, including time series properties. The artificial markets we discuss utilize models of “informed” trading agents who decide to trade based on received signals of the true or fundamental value of the stock, and “uninformed” tr...

The analysis of equilibrium in double auctions is complicated, with almost no closed-form examples and with formal results limited to bounds on bidding behavior. We consider the buyer’s bid double auction in a correlated, private values model. Sellers have the incentive to submit their costs as their asks while buyers strategically underbid. We determine (i) the asymptotic distribution of the e...

In an efficient market, the fundamental value of a security fluctuates randomly. However, trading costs induce negative serial dependence in successive observed market price changes. In fact, given market efficiency, the effective bid-ask spread can be measured by

Multiagent resource allocation defines the issue of having to distribute a set of resources among a set of agents, aiming at a fair and efficient allocation. Resource allocation procedures can be evaluated with regard to properties such as budget balance and strategy-proofness. Designing a budget-balanced and strategy-proof allocation procedure that always provides a fair (namely, envyfree) and...

One of the main functionalities of capital market is to improve liquidityin the market which provides security for the investors. Mutual funds aremodern financial institutions which are designed with the aim of collectingfunds from investors and devote them to buy a variety of securities inorder to mitigate investment risks, exploit the economies of scale andfinally create a reasonable return f...

As a long term bidding behavior, bid shading is exhibited by wind farms participating in real Uniform Price (UP) markets. This signifies that the wind farm owners bid far below their true long run marginal cost. In this paper, a method is proposed to consider the uncertainty of bidding admission in the long term expected revenue of wind farms. We show that this consideration could perfectly exp...
