"In the future data communication networks interoperability becomes critical from both technological and business strategy perspective. Significance of interoperability has to be evaluated in terms of the overall economic performance of the system. In this paper we will present our view of the...

A stylized fact from laboratory experiments is that there is much heterogeneity in human behavior. We present and demonstrate a computationally practical non-parametric Bayesian method for characterizing this heterogeneity. In addition, we define the concept of behaviorally distinguishable...

While multiple data vendors have claimed to offer a comprehensive international coverage of accounting and financial items for firms worldwide, there is a growing demand for better understanding of the differences across international databases. This paper compares several international...

The integration of Datastream and Worldscope databases at the Wharton Research Data Services (WRDS) offers researchers a simple solution to bypass the cumbersome data collection and preparation process for global empirical research. This study guide proposes a clean approach to link these two...

As machines replace humans in financial markets, how is informational efficiency impacted? We shed light on this issue by exploiting a unique data-set that allows us to identify when machines access important company information (8-K filings) versus when humans access the same information. We...

This paper exploits newly available information on firms' direct (own production) and indirect (supplier-generated) carbon emission intensities and transaction-level imports to conduct an in-depth analysis of whether and how U.S. firms address climate change. We find robust evidence that U.S....

As online video platforms (OVPs) prosper, advertisements in videos increase in both quantities and formats. Pre-roll and interpolation are two most popular advertising modes. While preroll disconnects with the content and mandatorily plays before videos, interpolation deeply embeds in the...

This study examines whether and how competition affects corporate strategic responses to stringent environmental policies. Using the nonattainment status of U.S. counties as a source of exogenous variation in environmental regulation, we find that competition fosters green innovation as firms...

Using numeric and textual data extracted from over 50,000 finance articles in SSRN during 2001--2019, we examine the relationship between measured qualities and a paper’s readership, eventual outlet, and impact. Conventionality (semantic similarity with existent research) helps boost...

This paper examines whether and how existing competitors producing similar products and supplying to common corporate customers (connected peer firms) influence a firm's strategic disclosure of adverse information. Results show that when faced with intense competition from existing competitors,...
