In this paper we show that George et al. (GKN, 1991) estimators of the adverse selection and order processing cost components of the bid-ask spread are biased due to intertemporal variations in the bid-ask spread. We use alternative estimators that correct this bias and that are applicable to...

In this paper we show that George, Kaul and Nimalendran's (GKN) estimators of the adverse selection and order processing cost components of the bid-ask spread are biased due to intertemporal variations in the bid-ask spread. We provide new estimators that correct this bias and that are...

Transaction costs are important for a host of empirical analysis from market efficiency to international market research. But transaction costs estimates are not always available; or where available, cumbersome to use and expensive to purchase. We present a model that requires only the time...

This paper argues that an aggregate preferred habitat for investors exists on (or about) the last day of the calendar month, due to standardizations in the nation's payments system resulting in a concentrated flow of funds on this date. Thus, equilibrium yield discounts are predicted for...
