I provide a theoretical model for two empirical phenomena observed in the NYSE and Nasdaq markets. First is the bid-ask bounce recently studied by Heston, Korajczuk and Sadka (HKS, 2008) for high-frequency data. Second is a temporary liquidity squeeze observed by Madureira and Underwood (2008)...

We analyze commonality in informed trading across stocks, and how informed trading varies with the structural and trading characteristics of a firm. We thereby isolate the residual level of informed trading that is unrelated to commonality, trading characteristics, and structural...

A new alternative diffusion model for asset price movements is presented. In contrast to the popular approach of Brownian motion it proposes deterministic diffusion for the modelling of stock price movements. These diffusion processes are a new area of physical research and can be created by the...

Inter-dealer trading in US Treasury securities is almost equally divided between two electronic trading platforms that have only slight differences in terms of their relative liquidity and transparency. BrokerTec is more active in the trading of 2-, 5-, and 10-year T-notes while eSpeed has more...

The Romanian financial market has passed in the last years through a large “maturating” and consolidation process which has created an unfinished architecture, harmonising step by step with the capital markets from European Union. One possible way to analyse the empirical characteristics of...

Nowadays there is a large debate on whether the financial information proves any relevance for the investors´ prediction of the securities market values/stock prices. The paper focuses, besides reviewing some important literature concerning this issue, on an empirical analysis taking into...

Many financial studies are based on the efficient capital markets hypothesis. In this context, testing the existence of this concept becomes an interesting field of study for the emerging capital market. The aim of this paper is to enlighten the difficulties of portfolio construction in a...

I present evidence that higher frequency measures of inflation expectations outperform lower frequency measures of inflation expectations in tests of accuracy, predictive power, and rationality. For decades, the academic literature has focused on three survey measures of expected inflation: the...

This study tests the price linkage among the U.S. major energy sources, considering structural breaks in time series. We use the Johansen cointegration method and find that only weak linkage sustains among the NYMEX WTI crude oil, Brent crude oil, gasoline, heating oil, coal, natural gas,...

This paper investigates whether or not multivariate cointegrated process with structural change can describe the Brazilian term structure of interest rate data from 1995 to 2006. In this work the break point and the number of cointegrated vector are assumed to be known. The estimated model has...
