In this paper we propose a simple Bayesian block wavelet shrinkage method for estimating an unknown function in the presence of Gaussian noise. A data-driven procedure which can adaptively choose the block size and the shrinkage level at each resolution level is provided. The asymptotic property...

This paper investigates how performance risk impacts a board's ability to learn about the unknown talent of a chief executive officer (CEO). We theorize that the information content of performance is increasing in idiosyncratic risk and decreasing in systematic risk. We provide robust empirical...

Empirical Bayes approaches to the shrinkage of empirical wavelet coefficients have generated considerable interest in recent years. Much of the work to date has focussed on shrinkage of individual wavelet coefficients in isolation. In this paper we propose an empirical Bayes approach to...

Remaining useful life (RUL) prediction is central to the prognostics and health management (PHM) of lithium-ion batteries. This paper proposes a novel RUL prediction method for lithium-ion batteries based on the Wiener process with measurement error (WPME). First, we use the truncated normal...

We examine the relation between audit committee compensation and the demand for monitoring of the financial reporting process. We find that total compensation and cash retainers paid to audit committees are positively correlated with audit fees and the impact of the Sarbanes-Oxley Act, our...

<heading id="h1" level="1" implicit="yes" format="display">ABSTRACT</heading>I study how increased internal control disclosure requirements mandated by the Sarbanes-Oxley Act (SOX) affect annual corporate governance decisions regarding CFOs. Using non-CEO, non-COO executive officers as a control group, I find that CFOs of firms with weak internal controls receive...

Purpose – The purpose of this study is to examine whether corporate tax avoidance behavior increases firm value in Chinese context. A large number of studies conduct their designs on the consumption that tax avoidance represents wealth transfer from government to enterprises and therefore...
