Estimating the Order-Flow Component of Security Returns
نویسندگان
چکیده
We derive a structural model of the amount of private information that is conveyed to the market via order flows. The model is a continuous-time Kyle model in which there is public information arrival and in which the strategic trader may or may not have private information. For empirical implementation, we treat each trading day as a separate instance of the model. Monte Carlo analysis shows that the key parameters are estimated well by maximum likelihood using intraday data over monthly time periods, even in the presence of some misspecification. We illustrate the procedure by estimating the model monthly for a single stock over a twenty-year time frame.

Estimating Returns to Scale in the Presence of Undesirable Factors in Data Envelopment Analysis
This research identifies returns to scale (RTS) of efficient decision making units (DMUs) with desirable (good) and undesirable (bad) inputs and outputs by presenting a new DEA (data envelopment analysis) approach. In this study, we first introduce a new input-output oriented model to determine efficient DMUs in the presence of undesirable factors and then, returns to scale of these DMUs are es...
متن کاملEstimating piping around bridge piers using the SSIIM software
Estimating maximum scour depth is normally required in order to determine the depth of bridge piles. The present paper uses the SSIIM Software which considers flow and sediment equations in a three dimensional manner. The software models flow field around circular bridge pile by resolving Navier-Stokes three-dimensional equations and k- method, and by temporary solution of flow field and cont...
متن کاملStudying the Expected Returns Based on Carhart Model Com-pared to CAPM Model and Implicit Capital Cost Model Based on Cash and Capital Flow of Growth and Value stocks
The purpose of this study was to examine the expected returns of Carhart model compared to the capital asset pricing model and the implicit capital cost model based on cash and capital returns of growth and value stocks. The statistical population consisted of the companies listed in Tehran Stock Exchange and the time domain is between 2007 and 2016. By choosing Cochran sampling, 126 companies ...
متن کاملAssessment of Corrective Methods for Estimating Suspended Sediment Load for Rivers with Debris Sediment Flow Regime in Khorramarood River - Golestan Province
In the present research, changes in sediment regime in two statistical periods of "natural flow" and "modified / debris flow" were evaluated. In order to determine the significant difference between two mentioned periods (1966-1992) and (1993-2015), the significance test was used. In order to determine the most suitable method of Sediment Rating Curve and correction coefficients, the result...
