Regulated short selling transactions is an alternative that was introduced by the Syariah Advisory Council (SAC), which attached to Securities Commission Malaysia, implement in Malaysia. Short not permitted because it involves various Shariah-related issues, including usury, uncertainty (ghārar), gambling, speculation etc. Since has advantageous terms of liquidity and opportunities for inves...

We examine how investor preferences and beliefs affect trading in relation to past gains and losses. The probability of selling as a function of profit is V-shaped; at short holding periods, investors are more likely to sell big losers than small ones. There is little evidence of an upward jump in selling at zero profits. These findings provide no clear indication that realization preference ex...

(a) The observed bidding patterns depend on the type of asset under evaluation. In particular, subject behavior when buying or selling a basic lottery seems much more cautious than their behavior when buying or selling options on that lottery. (b) The observed bidding patterns also depend on subject positions with respect to the underlying asset. In particular, the bids for buying lotteries and...

The valuation theory for American Contingent Claims, due to Bensoussan (1984) and Karatzas (1988), is extended to deal with constraints on portfolio choice, including incomplete markets and borrowing/short-selling constraints, or with different interest rates for borrowing and lending. In the unconstrained case, the classical theory provides a single arbitrage-free price u0; this is expressed a...

We show that randomly-selected Reg SHO pilot firms respond to increased threats of short selling by significantly improving their employee relations. Pilot firms enhance employee security to reduce the likelihood of negative announcements that might attract short-selling interest. Consistent with expectations, we find that the largest employee-relation improvements occur among pilot firms that ...

This paper presents a mathematical model of inventory control problem for determining the minimum total cost of multi-item multi-objective inventory model with fuzzy estimated price dependent demand, fuzzy deterioration and possible constraints. Here, three constraints we have taken; they are warehouse space constraint, investment amount constraint and the third constraint is the percentage of ...

I study the extent to which security lending fees affect prices in the context of search frictions in the repo market, and make three main theoretical contributions to the literature on shortselling: 1) I incorporate heterogeneity in investors’ access to the repo market, and show that securities become slowly “locked up” from the repo market as short interest builds up; 2) I provide testable pr...

We demonstrate the existence of an optimal, individually rational, and incentive compatible selling mechanism for a multiproduct monopolist facing a market populated by consumers with budget constraints. Our main contribution is to show via examples and our existence result that, in general, when facing consumers with budget constraints the monopolist is able to maximize profits over the set of...
