The costly trade theory predicts that it is much more difficult to exploit long-term private information than short-term. Thus, there is less long-term information impounded in prices. The managerial myopia theory predicts that a variety of short-term pressures, including inadequate information...

Abstract: We examine investor order choices using evidence from a recent period when the NYSE trades in decimals and allows automatic executions. We analyze the decision to submit or cancel an order or to take no action. For submitted orders, we distinguish order type (market vs. limit), order...
