We explain when and how staggered difference-in-differences regression estimators, commonly
applied to assess the impact of policy changes, are biased. These biases are likely to …

Over the last decade, the introduction of microarray technology has had a profound impact
on gene expression research. The publication of studies with dissimilar or altogether …

A simple empirical relation is found to exist between the linear and the third-order nonlinear
optical susceptibilities. This empirical relation holds within the available experimental …

Applying a “co-search” algorithm to Internet traffic at the SEC׳s EDGAR website, we develop
a novel method for identifying economically related peer firms and for measuring their …

Firms with central boards of directors earn superior risk-adjusted stock returns. A long (short)
position in the most (least) central firms earns average annual returns of 4.68%. Firms with …

The correlation between governance indices and abnormal returns documented for 1990–1999
subsequently disappeared. The correlation and its disappearance are both due to …

The concordance of RNA-sequencing (RNA-seq) with microarrays for genome-wide analysis
of differential gene expression has not been rigorously assessed using a range of chemical …

Newsvendor models are widely used in the literature, and usually based upon the
assumption of risk neutrality. This paper uses loss aversion to model manager's decision-making …

To validate and extend the findings of the MicroArray Quality Control (MAQC) project, a
biologically relevant toxicogenomics data set was generated using 36 RNA samples from rats …

Background Gene expression profiling is being widely applied in cancer research to identify
biomarkers for clinical endpoint prediction. Since RNA-seq provides a powerful tool for …
