A model is presented in which firms optimally finance investment with both public and private debt. The two instruments are perfect substitutes, except that private debt can easily be renegotiated in insolvency states while public debt cannot. The option to renegotiate is beneficial ex post, as it allows the firm to avoid inefficient liquidation, but ex ante it may worsen asset substitution. The welfare effects of alternative bankruptcy regimes are then compared, taking into account that firms modify their financing decision in response to the regime change. Some suggestions for reforming Chapter 11 of the U.S. bankruptcy code are presented. Journal of Economic Literature Classification Numbers: G32, G33, K2.

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.

Projects with negative expected value cannot obtain financing in competitive capital markets if all potential investors are risk neutral and have identical beliefs about the distribution of the project′s net revenue. We present a series of examples with heterogeneous beliefs in which it is possible for a project to obtain financing even though all investors in the project believe, conditional on the project being undertaken, that the project has negative expected value. An important feature of the examples is that the differences in beliefs are due only to differences in information, and are not simply arbitrary unexplained differences in opinions.

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.

This paper considers the extent to which loan commitments mitigate the problems of information monopolies that arise when the firm contracts with a private lender. Loan commitments in conjunction with short-term debt often provide the firm with superior investment incentives by influencing both the states in which bargaining occurs as well as the outcomes from bargaining. Commitment contracts are particularly valuable when there is a high likelihood that information about the firm will be publicly revealed ex post. We also identify circumstances under which the firm foregoes commitment financing, relying on short-term debt instead. Journal of Economic Literature Classification Numbers G21, G32, D82.

This paper considers the costs and benefits of inflation using a stochastic version of Townsend′s turnpike model in which agents of each type are allowed to remain at a trading post for multiple periods. Numerical results show that moderate rates of inflation can be welfare-improving, but only when private credit markets are extremely limited. More generally, the existence of private credit markets curtails the ability of inflationary policy to do both harm and good. In addition, the welfare consequences of inflation depend on how much information about the economy the government has access to when implementing its policies.

This paper investigates the incentives of a regulator to close depository institutions, recognizing that an institution′s risk taking will be influenced by the regulator′s policy regarding bank closure and that there are opportunity costs in closing banks arising from their intermediation function. The regulator focuses not on the current portfolio of the bank, but on the bank′s future portfolio. Even if the regulator seeks to maximize welfare, the first best is not obtainable because the regulator is unable to credibly commit to certain policies regarding closure.
