We initially derived elevation changes of Geoscience Laser Altimeter System level-2 altimetry data of Lambert Glacier overlapping footprints during each mission from 2003 to 2008. Then, surface elevation changes during every two adjacent missions were interpolated using inverse distance...

A simple deterministic algorithm for community detection is provided by using two rounds of minimum spanning trees. By comparing the first round minimum spanning tree (1st-MST) with the second round spanning tree (2nd-MST) of the network, communities are detected and their overlapping nodes are...

This paper analyzes executive compensation in a setting where managers may take a costly action to manipulate corporate performance, and whether managers do so is stochastic. We show that an increase in the possibility of manipulation actually calls for executive pay to be more responsive to...

Motivated by social and biological interactions, a novel type of phase transition model is provided in order to investigate the emergence of the clustering phenomenon in networks. The model has two types of interactions: one is attractive and the other is repulsive. In each iteration, the phase...

increased idiosyncratic volatility. The calibration results further indicate that earnings management by individual firms does not only deliver the observed features in their own stocks, but can also be strong enough to generate market-wide patterns.

Regulatory investigations affect information in financial markets through two channels: (i) investigations detect financial manipulation and reveal hidden negative information;(ii) regulatory investigations impose adverse consequences for executives involved in manipulation and deter managerial...

The research question of why earnings management occurs is decomposed into two questions in this article: Which component of executive compensation generates incentives for earnings management? and Why is the compensation structured that way in the first place? We first use as a dynamic...

To expand enterprises is a question receiving much concern. At least it needs to consider questions of scale, culture, control and strategy. From appearance, reasonable scale, harmonious culture, peace talk of control and strategy in steps make the face of enterprises¡¯ expansion; from the...

We analyze the impact of bad-tail risks on managerial pay functions, especially the decision to pay managers in stock or in options. In contrast to conventional wisdom, we find that options are often a superior vehicle for limiting managerial incentives to take bad-tail risks while providing...

We analyze a model of anomaly discovery. Consistent with existing evidence, we show that the discovery of an anomaly reduces its magnitude and increases its correlation with existing anomalies. One new prediction is that the discovery of an anomaly reduces the correlation between deciles 1 and...
