ABSTRACT We examine how non‐CEO executives (NCEs) serving on outside boards affect their focal firm performance. Firms with such NCEs exhibit lower return on asset (ROA) and profit margins than those without. These effects begin after board service starts, are not explained by busy boards or CEOs, and persist at least a year.

Relaxing the Gaussian assumption in Shrinkage and SURE in high dimension
Shrinkage estimation is a fundamental tool of modern statistics, pioneered by Charles Stein upon the discovery of his famous paradox. Despite a large subsequent literature, the efficiency of shrinkage, and the associated procedure known as Stein's ...

Early stopping and non-parametric regression: An optimal data-dependent stopping rule
The strategy of early stopping is a regularization technique based on choosing a stopping time for an iterative algorithm. Focusing on non-parametric regression in a reproducing kernel Hilbert space, we analyze the early stopping strategy for a form of ...

Networks are a popular tool for representing elements in a system and their interconnectedness. Many observed networks can be viewed as only samples of some true underlying network. Such is frequently the case, for example, in the monitoring and study of

A method of determining the optimum number of levels of decomposition in soft-thresholding wavelet denoising using Stationary Wavelet Transform is presented here. The method calculates the risk at each level of decomposition using Steins Unbiased Risk Estimate, analogous to calculating the sum square error of the denoising process.

Applying the Grinblatt-Titman and the Conditional (Ferson-Schadt) Performance Measures: The Case of Industry Rotation Via the Dynamic Investment Model. [PDF]
Nearly any standard financial model concludes that two assets with identical cash flows must sell for the same price. Alas, closed-end mutual fund company share prices seem to violate this fundamental tenant.
