Nonlinear dynamics and competing behavioral interpretations: Evidence from intra‐day FTSE‐100 index and futures data

Extant empirical research has reported nonlinear behavior within arbitrage relationships. In this article, the authors consider potential nonlinear dynamics within FTSE‐100 index and index‐futures. Such nonlinearity can be rationalized by the existence of transactions costs or through the interaction between informed and noise traders. They consider several empirical models designed to capture these alternative dynamics. Their empirical results provide evidence of a stationary basis term, and thus cointegration between index and index‐futures, and the presence of nonlinear dynamics within that relationship. The results further suggest that noise traders typically engage in momentum trading and are more prone to this behavior type when the underlying market is rising. Fundamental, or arbitrage, traders are characterized by heterogeneity, such that there is slow movement between regimes of behavior. In particular, fundamental traders act more quickly in response to small deviations from equilibrium, but are reluctant to act quickly in response to larger mispricings that are exposed to greater noise trader price risk. © 2006 Wiley Periodicals, Inc.

LBOs,Reversions and Implicit Contracts

The conventional view of going-private transactions is that they are designed to enhance the efficiency of the firm (for example, Jensen (1986) ). A starkly different view is that these and other control transactions are motivated to effect transfers from other stakeholders in the firm to equity holders ( Shleifer and Summers (1988) ). This study exploits data describing pension terminations as a way to test these theories. We conclude that the efficiency theory can plausibly explain a substantial number of LBO-related terminations, but not enough to undermine the transfer theory. More specific predictions from the efflciency theory are needed to structure more exacting tests.
