We assess the effect of four short-sale constraints on stock returns in isolation and in combination, in generally falling versus generally rising markets, and considering relative effects for large/mid cap versus small/micro cap firms. We find that across our variety of model specifications, there is substantial evidence that our more fully specified model provides considerable additional expl...

Very often computer scientists view computerization of services in terms of the logistics of humanmachine interaction, including establishing a contract, accessing records, and of course designing an interface. But this analysis often moves too quickly to tactical details, failing to frame the entire service in human terms, and not recognizing the mutual learning required to define and relate g...

For utility maximization problems under proportional transaction costs, it has been observed that the original market with transaction costs can sometimes be replaced by a frictionless shadow market that yields the same optimal strategy and utility. However, the question of whether or not this indeed holds in generality has remained elusive so far. In this paper we present a counterexample whic...

Personal selling is thought to be a very effective marketing vehicle. The notion of adaptive selling suggests that it should work better than any other means of communication because salespeople are able to develop a unique message for each customer. This research proposes a model of key antecedents and consequences of adaptive selling. In particular, we distinguish, measure, and model the atti...

The advance selling strategy is implemented when a firm offers consumers the opportunity to order its product in advance of the regular selling season. Advance selling reduces uncertainty for both the firm and the buyer and enables the firm to update its forecast of future demand. The distinctive feature of the present study of advance selling is that we divide consumers into two groups, experi...

Commodity money arises endogenously in a general equilibrium model with separate budget constraints for each transaction. Transaction costs imply differing bid and ask (selling and buying) prices. The most liquid good—with the smallest proportionate bid/ask spread—becomes commodity money. General equilibrium may not be Pareto efficient. If zero-transaction-cost money is available then the equil...

In this paper, we formulate a mean-variance portfolio selection model with liability under the constraint that short-selling is prohibited. Due to the introduction of the liability and no-shorting constraints, our problem is not a conventional stochastic optimal linear-quadratic(LQ) control problem, and the corresponding HJB equation has no continuous solution. we construct a lower-semicontinuo...
