¿Se puede medir la negociación informada? Una revisión de la metodología basada en las covarianzas de las series de precios

As theoretical microstructure models developed, several researches have empirically investigated the relevant role of transaction costs and its components in the stock market dynamics and their applications in several similar topics (corporate finance, market efficiency, etc.). Alternatively, empirical tests of these models has led to different results. In this paper, we perform a thorough study of a group of models with common characteristics. Specifically, we focus on models that estimate transaction cost components from price and/or return time series autocovariance.
