This paper investigates the relationship between a firm′s loan commitment demand and its overall capital structure. I develop a model which demonstrates that a loan commitment leads a firm to higher privately optimal debt level and a lower cost of debt funds; these results are driven by the loan commitment′s ability to attenuate the potential moral hazard problems attendant upon debt financing. I confront the predictions with cross-sectional data, and find that the availability of unused loan commitment financing is positively related to firm leverage and negatively related to cost of debt funds.

Investment advisory firms and brokerage firms hire analysts to uncover profitable securities investment opportunities. Then these firms sell the information (either directly or indirectly) to others. Why? Given that the information has value, why do these firms not keep the information to themselves and trade solely for their own accounts? Because of competition, information is more valuable when fewer people trade on the information. This paper shows that selling information is a strategic response by competing informed traders. Specifically, it is a means for informed traders to commit to trade aggressively, thereby inducing other informed traders to trade less aggressively.

This paper examines the change in trading costs for firms that choose to move from a dealer market to a specialist system. Using transactions data, our empirical results reveal structurally induced average trading cost reductions of 4.7 (5.2) cents per share for firms that moved from the NASDAQ/NMS to the NYSE (AMEX) in 1990. For NYSE listed stocks, the trading cost reductions are equally divided between quote improvements and the routing of trades to the NYSE. Trading cost improvements vary inversely with trade sizes and positively with dollar spreads. Finally, the greatest liquidity benefits from listing accrue to the less liquid stocks.

We examine the lead–lag relation between intraday spot and futures prices for a stock index where the component stocks are floor traded while the futures contract is screen traded. We find that futures prices lead spot prices by nearly 20 min. This is much longer than in markets where both the index and index futures are floor traded. We show that this lead–lag relation is unlikely to be an artifact of differences in liquidity between the spot and futures markets. These results are consistent with the hypothesis that screen trading accelerates the price discovery process. Journal of Economic Literature Classification Numbers: F33, G15, G20, O31.

This paper analyzes a simple mobility-based model of mortgage lending and uses the results to illuminate the issue of mortgage points. The model predicts the points/interest-rate trade-off observed in the market, and it also predicts that mobile borrowers choose low-points/high-rate contracts from the available menu, in conformance with conventional wisdom. These outcomes are shown to be a result of adverse selection, which arises because of the lender′s inability to distinguish the mobility characteristics of borrowers. Empirical evidence is also presented showing the presence of a points/interest-rate trade-off in the market. In addition, relying on a proxy variable, the results establish that borrowers choose contracts from this menu according to mobility. Journal of Economic Literature Classification Numbers: G21.

This paper studies the use of cash and credit for making transactions when there is asymmetric information in credit markets. For relatively low inflation rates, equilibria are of the pooling variety and low-credit-risk consumers signal their riskiness to lenders only indirectly by establishing a good track record in credit markets. For higher inflation rates there may exist a separating equilibrium in which low-credit-risk consumers directly signal their type to lenders by specializing in cash early in life and specializing in credit later in life. The greater the degree of adverse selection in credit markets, the wider the range of inflation rates for which a separating equilibrium exists. Credit usage is increasing in the inflation rate, but greater adverse selection may increase or decrease credit usage depending on the parameterization.

According to conventional theory, insurance premiums should be informationally efficient predictors of the present value of policy claims and expenses. This paper develops an alternative theory of insurance market dynamics based on two assumptions. First, insured risks are dependent. Under this assumption, insurers′ net worth determines the market capacity since it is necessary to back the contractual promises to pay claims. Second, in raising net worth, external equity is more costly than internal equity. The theory explains the variation in premiums and insurance contracts over the "insurance cycle" and is supported by tests on postwar data.

It is shown that the models of Spiegel and Subrahmanyam (1992, Rev. Finan. Stud.5(2), 307–329) and Kyle (1985, Econometrica53, 1315–1335) are equivalent in the following sense: the equilibrium values of market depth, the expected total trading volume and the expected price level are the same in the two models. Equivalence exists whenever the uniformed traders hedge all of their endowments of risky shares. This occurs under two sets of parameter configurations. In both cases, the linear equilibrium in the hedger model always exists. Journal of Economic Literature Classification Numbers; G12, G14, D82.

This paper demonstrates how managers with private information about firms′ exposure to risk may, in the best interest of shareholders, engage in speculation instead of hedging as the conventional wisdom tells us. The reason is that when profits serve as a signal of firms′ values, speculative trades can be used to distort profits and hence manipulate stock prices to the shareholders′ advantage. A consequence of such corporate speculation is that stock prices become less informative about firms′ true worth. Journal of Economic Literature Classification Numbers: D82, G14, G32.
