The pooling equilibrium spread does not monotonically increase with α, although it increases ...
متن کاملExpected Return and the Bid-Ask Spread
This paper empirically examines the relation between the expected stock return and the bid-ask spread. Using the same portfolio formation method as in Amihud and Mendelson (1986) but different test methodologies, we do not find any clear reliable relation between the CAPM risk-adjusted return and the relative bid-ask spread. Our empirical results are more consistent with the conclusions of Cons...

متن کاملHow (Un)Informed Is Trading?
We estimate a structural model of strategic trader behavior that sheds light on the determinants of trading volume and stock returns. Our novel identification approach exploits enormous empirical variation in trading and volatility associated with the time of day and public news arrival. Over 95% of trading occurs during regular market hours (9:30am to 4pm), even though prices exhibit considera...
