Easley / Kiefer / O'Hara / Paperman (1996) (EKOP) have proposed an empirical methodology that allows to estimate the probability of informed trading and that has subsequently been used to address a wide range of issues in market microstructure. The data needed for estimation is the number of...

The problem of classifying trades as buys or sells is examined. I propose estimated quotes for midpoint and bid/ask tests and a modeling approach to classification. Prevailing quotes are estimated using flexible approximations to the distribution for delays of quotes relative to trade...

En este estudio se estima la probabilidad de transacciones informadas comportamiento y sus efectos en los rendimientos diarios e intradiarios en Latinoamérica. Calculando la probabilidad diaria dinámica de transacciones informadas (Easley, Engle, O´Hara y Wu, 2008), como una medida del nivel...

The link between informed trading and the bid-ask spread has been the focus of abundant literature and some authors feared that a large amount of informed trading might lead to shutdown of markets. We explore this issue using data from the Czech Republic. Our estimates confirm that the share of...

A continuous time econometric modelling framework for multivariate financial market event (or `transactions`) data is developed in which the model is specified via the vector stochastic intensity. This has the advantage that the conditioning sigma-field is updated continuously in time as new...

A continuous time econometric modelling framework for multivariate financial market event (or `transactions') data is developed in which the model is specified via the vector stochastic intensity. This has the advantage that the conditioning sigma-field is updated continuously in time as new...

A continuous time econometric modelling framework for multivariate financial market event (or 'transactions') data is developed in which the model is specified via the vector conditional intensity. This has the advantage that the conditioning information set is updated continuously in time as...

Two important characteristics of current equity markets are the large number of trading venues with publicly displayed order books and the substantial fraction of trading that takes place in the dark, outside such visible order books. This paper evaluates the impact of dark trading and...

We examine the consequences of transparency in an experimental multiple-dealer market with asymmetrically informed dealers. Five professional securities traders make a market for a single security. In each trading round, one of the dealers (the "insider") is told the security's true value. We...
