We derive the expressions of asymptotic biases when ignoring the misclassification in a multicategory exposure. For a model with a misclassified exposure variable only, we provide a general conclusion on the direction of the biases under nondifferential misclassification assumption. To better...

Graphene, a rapidly rising star on the horizon of material science, has a unique two-dimensional nanostructure as well as exceptional mechanical, optical and electronic properties. Despite its short history, graphene has exhibited great potential applications in counter electrodes, acceptor and...

This paper considers informed traders' trading strategy in a bear market. Known as stealth trading, informed traders use medium-size trades, which tend to contain more information than small and large trades, and have stronger impact on stock price movement. Using the transaction data provided...
