The investment boundaries defined by Grenadier (2002) for an oligopoly investment game determine equilibria in open-loop strategies. As closed-loop strategies, they are not equilibria, because any firm by investing sooner can preempt the investments of other firms and expropriate the growth...

In an extension of the Kyle (1985) model of continuous insider trading, it is shown that asymmetric information can make it impossible to price options by arbitrage. Even when an option would appear to be redundant, its introduction into the market can cause the volatility of the underlying...

The continuous-time version of A. Kyle's (1985) model of asset pricing with asymmetric information is studied. It is shown that there is a unique equilibrium pricing rule within a certain class. This pricing rule is obtained in closed form for general distributions of the asset value. A...

Portfolio turnpike theorems show that if preferences at large wealth levels are similar to power utility, then the investment strategy converges to the power utility strategy as the horizon increases. We state and prove two simple and general portfolio turnpike theorems. Unlike existing...

We compare a sealed-bid uniform-price auction (the Treasury's experimental format) with a sealed bid discriminatory auction (the Treasury's format heretofore), assuming the good is perfectly divisible. We show that the auction theory that prompted the experiment, which assumes single-unit...

We examine the costs and benefits of the global integration of initial public offering (IPO) markets associated with the diffusion of U.S. underwriting methods in the 1990s. Bookbuilding is becoming increasingly popular outside the United States and typically costs twice as much as a fixed-price...

Why don't VCs eliminate excess demand for follow-on funds by raising fees? We propose a model of learning that leads to informational holdup. Current investors learn about skill whereas outside investors observe only returns. This gives current investors holdup power when the VC raises his next...

We provide evidence for the importance of information asymmetry in asset pricing by using three natural experiments. Consistent with rational expectations models with multiple assets and multiple signals, we find that prices and uninformed demand fall as asymmetry increases. These falls are...

We show that relatively optimistic research and even the mere provision of research coverage for the issuer (regardless of its direction) attract co-management appointments for securities offerings. Co-management appointments are valuable because they help banks establish relationships with...
