Exchange-mandated discrete pricing restrictions create a wedge between the underlying equilibrium price and the observed price. This wedge permits a competitive market maker to realize economic profits that could help recoup fixed costs. The optimal tick size that maximizes the expected profits of the market maker can equal to $1/8 for reasonable parameter values. The optimal tick size is decreasing in the degree of adverse selection. Discreteness per se can cause time-varying bid-ask spreads, asymmetric commissions, and market breakdowns. Discreteness, which imposes additional transaction costs, reduces the value of private information. Liquidity traders can benefit under certain conditions.

[We examine the behavior of call options surrounding the underlying stock's ex-dividend date. The evidence is inconsistent with the predictions of a rational exercise policy; a significant fraction of the open interest remains unexercised, resulting in a windfall gain to option writers. This triggers a sophisticated trading scheme that enables short-term traders to receive a significant fraction of the gains. The trading scheme inflates reported volume and distorts its traditional relations to liquidity. The dramatic increases in the volume of trade on the last cum-dividend day are facilitated by limitations on transaction costs passed by the various option exchanges.]

We consider the design of securities that govern the distribution of cash flows and control rights for an investment project. An entrepreneur, endowed with managerial talent, contracts with an outside investor for required capital. Optimal contracts stipulate that the ownership of control and the distribution of cash flows are specified on a state contingent basis to manage the distortions that develop from the use of outside financing and so make the best use of the advantage in project management enjoyed by insiders. Our results illustrate that the use of warrants and convertible securities, which transfer control of the firm to outsiders in good states, and bankruptcy, which transfers control to outsiders in bad states, are related features of optimal contracts. Our model also indicates that firms will benefit from direct access to two types of bankruptcy processes resembling Chapter 7 and Chapter 11 (including deviations from absolute priority) of the bankruptcy code. This results differs from observed practices since stockholders cannot waive their rights for protection under Chapter 11. We show that when direct access to Chapter 7 is highly valuable, market participants have found clever ways to obtain it.Journal of Economic LiteratureClassification Numbers: G32 and G33.

ABSTRACT We use the move of Israeli stocks from call auction trading to continuous trading to show that investors have a preference for stocks that trade continuously. When large stocks move from call auction to continuous trading, the small stocks that still trade by call auction experience a significant loss in volume relative to the overall market volume. As small stocks move to continuous trading, they experience an increase in volume and positive abnormal returns because of the associated increase in liquidity. Overall, though, a move to continuous trading increases the volume of large stocks relative to small stocks.

We show that estimating demand and supply elasticities at the opening stage of trading at the Tel Aviv Stock Exchange is highly sensitive to which of several reasonable measures is used. We find that the demand curve is more elastic than the supply curve and that both are much more elastic in their “executable” areas. The empirical evidence indicates that elasticity is increasing during the continuous stage of trading. We discuss methods of estimation of price impact and document that the actual measure of price impact in call auctions is larger and more permanent for buys than for sells.

ABSTRACT This paper proposes a new method using option prices to estimate the market value of the shareholder voting rights associated with a stock. The method consists of synthesizing a nonvoting share using put‐call parity, and comparing its price to that of the underlying stock. Empirically, we find this measure of the value of voting rights to be positive and increasing in the time to expiration of synthetic stocks. The measure also increases around special shareholder meetings, periods of hedge fund activism, and M&A events. The method is likely useful in studies of corporate control and also has asset pricing implications.

ABSTRACT We examine the role of the coupon choice in bond contracts as a signaling mechanism in the presence of information asymmetry between borrowers and lenders about the credit quality of the borrower. Prior literature focuses on the use of maturity as a signaling mechanism. We conjecture that the coupon is a more effective signaling mechanism. We exploit the enactment of Regulation Fair Disclosure (RegFD) as an exogenous shock to the level of information asymmetry, and employ both bond- and equity market-based variables of information asymmetry to test our conjecture. We find that following the enactment of RegFD, the coupon rates of bonds issued by unrated firms increase relatively more than those of rated firms, consistent with the coupon choice addressing information asymmetry. We fail to find similar increases in maturity. Our inferences remain the same when using the probability of informed trade to measure relative changes in information asymmetry around the enactment of RegFD. We also draw similar conclusions utilizing exogenous drops in analyst coverage that result from brokerage house closures as an alternative quasi-natural experiment. Finally, we provide evidence that the coupon is used more extensively when issuance costs are higher, precisely when maturity is predicted to be a less efficient contract term with which to address information asymmetry.
