This paper implements the Asymmetric Autoregressive Conditional Duration (AACD) model of Bauwens and Giot (2003) to analyze irregularly spaced transaction data of trade direction, namely buy versus sell orders. We examine the influence of lagged transaction duration, lagged volume and lagged...

We apply the ACD-ICV method proposed by Tse and Yang (2011) for the estimation of intraday volatility to estimate monthly volatility, and empirically compare this method against the re- alized volatility (RV) and generalized autoregressive conditional heteroskedasticity (GARCH) methods. Our...

In the last decade, intensive studies on modeling high frequency financial data at the transaction level have been conducted. In the analysis of high-frequency duration data, it is often the first step to remove the intraday periodicity. Currently the most popular adjustment procedure is the...

In this paper, we apply a collection of parametric (Normal, Normal GARCH, Student GARCH, RiskMetrics and high-frequency duration models) and non-parametric (empirical quantile, extreme distributions models) Value-at-Risk (VaR) techniques to intraday data for three stocks traded on the NewY ork...

This paper studies the impact of news announcements on trade durations in stocks on the Stockholm Stock Exchange. The news are categorized into four groups and the impact on the time between transactions is studied. Times before, during and after the news release are considered. Econometrically,...

This paper considers an extension of the univariate autoregressive conditional duration model to which durations from a second stock are added. The model is empirically used to study durations in two traded stocks, Ericsson B and AstraZeneca, on the Stockholm Stock Exchange. It is found that...

We analyse the impact of the introduction of the French Tobin tax on volumes, liquidity and volatility of a ected stocks with parametric and non parametric tests on individual stocks, di erence in di erence tests and other robustness checks controlling for simultaneous month-of-the-year and size...

We analyse the impact of the introduction of the French Tobin tax on volumes, liquidity and volatility of affected stocks with parametric and non parametric tests on individual stocks, difference in difference tests and other robustness checks controlling for simultaneous month-of-the-year and...

We analyse the impact of the introduction of the French Tobin tax on volumes, liquidity and volatility of affected stocks with parametric and non parametric tests on individual stocks, difference in difference tests and other robustness checks controlling for simultaneous month-of-the-year and...

There is no single, widely-accepted definition of "market liquidity" even though the expression "market liquidity is high/low" is frequently used, and measuring market liquidity is not easy. Recognizing these challenges, this paper formulates a set of new liquidity indicators using transaction...
