We theoretically investigate the thermopower of silicene systems in an external electric field perpendicular to the silicene sheet. In the absence of the field, we estimate that the thermopower of pure silicene is of order ∼80 μV/K. When a finite field is applied, a comparatively big band gap...

In this paper, we propose a novel method for sparse logistic regression with non-convex regularization Lp (p 1). Based on smooth approximation, we develop several fast algorithms for learning the classifier that is applicable to high dimensional dataset such as gene expression. To the best of...

We consider energy (heat) transport in quantum systems, and establish a relationship between energy spread and energy current-current correlation function within linear response theory. The energy current-current correlation is related to thermal conductivity by the Green-Kubo formula, and thus...

This paper examines the incentive features of top-management compensation in the banking industry. Economic theory suggests that the compensation structures for bank management should have low pay-performance sensitivity because of the high leverage of banks and the fact that banks are regulated...

We hypothesize that CEO compensation is optimally designed to trade off two types of agency problems: the standard shareholder-management agency problem as well as the risk-shifting problem between shareholders and debtholders. Analyses in this setup produces two predictions: (1) the...

We study CEO compensation in the banking industry by taking into account banks unique claim structure in the presence of two types of agency problems: the standard managerial agency problem as well as the risk-shifting problem between shareholders and debtholders. We empirically test two...

We examine the impact of a firm's asymmetric information on its choice of three mechanisms of corporate governance: the intensity of board monitoring, the exposure to market discipline, and CEO pay-for-performance sensitivity. We find that firms facing greater asymmetric information tend to use...

Using a unique dataset of complete bid information for every IPO auction in Taiwan during 1995-2000, we examine the behaviors and returns of two groups - institutional and retail investors - in a setting in which underwriters do not have pricing or allocation discretion. We find that the bids of...
