We extend the theory of asymmetric information in mispricing models for stocks following geometric Brownian motion to constant relative risk averse investors. Mispricing follows a continuous mean-reverting Ornstein–Uhlenbeck process. Optimal portfolios and maximum expected log-linear utilities...

We study a discontinuous mispricing model of a risky asset under asymmetric information where jumps in the asset price and mispricing are modelled by Lévy processes. By contracting the filtration of the informed investor, we obtain optimal portfolios and maximum expected utilities for the...

This paper addresses how asymmetric information, fads and Lévy jumps in the price of an asset affect the optimal portfolio strategies and maximum expected utilities of two distinct classes of rational investors in a financial market. We obtain the investors’ optimal portfolios and maximum...

While there are economic motives and empirical support for spinoffs, about one in every four planned spinoffs is withdrawn. This study is the first to explain why some spinoffs are withdrawn. We find that the probability that a spinoff is withdrawn is inversely related to the share price...

This paper examines the impact of the Troubled Asset Relief Program (TARP) capital injections on the operational efficiency of commercial banks. Using a nonparametric Data Envelopment Analysis to measure bank efficiency, we document a deteriorating pattern in the operating efficiency for banks...

Purpose – Agency theory suggests that if managers are not monitored, takeover negotiations may be contaminated by agency conflicts, which may weaken a firm's bargaining position. This paper argues that some blockholders are more effective monitors than others, and tests whether the negotiating...

This paper examines the stock price reaction to cross-border spinoff announcements and investigates whether country characteristics (such as takeover market liquidity and investor protection) cause variation in the announcements' wealth effects. We observe a positive and significant price...
