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 be 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.

This article solves the equilibrium problem in a pure-exchange, continuous-time economy in which some agents face information costs or other types of frictions effectively preventing them from investing in the stock market. Under the assumption that the restricted agents have logarithmic utilities, a complete characterization of equilibrium prices and consumption/investment policies is provided. A simple calibration shows that the model can help resolve some of the empirical asset pricing puzzles.

We determine the minimum cost of superreplicating a nonnegative contingent claim when there are convex constraints on portfolio weights. We show that the optimal cost with constraints is equal to the price of a related claim without constraints. The related claim is a dominating claim, that is, a claim whose payoffs are increased in an appropriate way relative to the original claim. The results hold for a variety of options, including some path-dependent options. Constraints on the gamma of the replicating portfolio, constraints on portfolio amounts, and constraints on the number of shares are also considered.

We examine the predictive power of equilibrium dominance in experimental markets where firms with investment opportunities have an informational advantage over potential investors and are permitted to purchase a money-burning signal. Equilibrium dominance often fails to predict well when a Pareto-superior sequential equilibrium is also available. Instead, equilibrium selection appears to be related to the potential earnings of a more valuable firm that can signal its type successfully by defecting from the sequential equilibrium. Potential investors formulate their bids for firm equity based primarily on expectations formed adaptively in response to signaling choices made by firms.

While American calls on non-dividend-paying stocks may be valued as European, there is no completely explicit exact solution for the values of American puts. We use a technique called randomization to value American puts and calls on dividend-paying stocks. This technique yields a new semi-explicit approximation for American option values in the Black-Scholes model. Numerical results indicate that the approximation is both accurate and computationally efficient.

Fama (1977) and Miller (1977) predict that one minus the corporate tax rate will equate after-tax yields from comparable taxable and tax-exempt bonds. Empirical evidence shows that long-term tax-exempt yields are higher than theory predicts. Two popular explanations for this empirical puzzle are that, relative to taxable bonds, municipal bonds bear more default risk and include costly call options. I study U.S. government secured municipal bond yields which are effectively default-free and nonmalleable. These municipal yields display the same tendency to be too high. I conclude that differential default risk and call options do not explain the municipal bond puzzle.

This article presents evidence on persistence in the relative investment performance of large, institutional equity managers. Similar to existing evidence for mutual funds, we find persistent performance concentrated in the managers with poor prior-period performance measures. A conditional approach, using time-varying measures of risk and abnormal performance, is better able to detect this persistence and to predict the future performance of the funds than are traditional methods.

Recent empirical evidence indicates that capital structure changes affect pricing strategies. In most cases, prices increase following the implementation of a leveraged buyout of a major firm in an industry, with the more leveraged firm in the industry charging higher prices on average. Notable exceptions exist, however, when the leverage increasing firm's rival is relatively unlevered. The first observation is consistent with a model where firms compete for market share on the basis of price. The second observation can be explained within the context of a Stackelberg model where the relatively unlevered rival acts as the Stackelberg price leader.

I consider the costs and benefits of introducing a new security in a standard framework where uninformed traders with hedging needs interact with risk-averse informed traders. Opening a new market may make everybody worse off, even when the new security is traded in equilibrium. This article emphasizes cross-market links between hedging and speculative demands: risk-averse arbitrageurs can use the new market to hedge their positions in the preexisting security, which can affect liquidity in the old market. More generally, the availability of such hedging opportunities will influence the strategies to which traders will direct resources.
