Order Arrival, Quote Behavior, and the Return-Generating Process.

This paper establishes three empirical results. The authors find positive autocorrelation in actual intraday stock returns, in intraday returns computed from quot e-midpoints, and in the arrival of buy and sell orders. They present a model of return generation which incorporates these features via la gged adjustment of the limit-order price and positive dependence in b id and ask transactions. The return model is observationally equivale nt to an ARMA process which is consistent with the observed return be havior. Copyright 1987 by American Finance Association.
