Uncovering Synergy and Dysergy in Consumer Reviews: A Machine Learning Approach

Massive online text reviews can be a powerful market research tool for understanding consumer experiences and helping firms improve and innovate. This research exploits the rich semantic properties of text reviews and proposes a novel machine learning modeling framework that can reliably and efficiently extract consumer opinions and uncover potential interaction effects across these opinions, thereby identifying hidden and nuanced areas for product and service improvement beyond existing modeling approaches in this domain.

From Story Line to Box Office: A New Approach for Green-Lighting Movie Scripts

Movie studios often have to choose among thousands of scripts to decide which ones to turn into movies. Despite the huge amount of money at stake, this process-known as green-lighting in the movie industry-is largely a guesswork based on experts' experience and intuitions.

Data Analytics, Innovation, and Firm Productivity

We examine the relationship between data analytics capabilities and innovation using detailed firm-level data.

Predicting Risk Perception: New Insights from Data Science

We outline computational techniques for predicting perceptions of risk. Our approach uses the structure of word distribution in natural language data to uncover rich representations for a very large set of naturalistic risk sources. With the application of standard machine learning techniques, we are able to accurately map these representations onto participant risk ratings.

Competition, Contracts, and Creativity: Evidence from Novel Writing in a Platform Market

Abstract A growing number of people today are participating in the gig economy, working as independent contractors on short-term projects. We study the effects of competition on gig workers' effort and creativity on a Chinese novel-writing platform. Authors produce and sell their works chapter by chapter under a revenue-sharing or pay-by-the-word contract with the platform.

Recommending Remedial Learning Materials to Students by Filling Their Knowledge Gaps

We study the problem of providing recommendations to students that help them in their studies. To address this problem, we present an approach of providing recommendations of remedial learning materials to students that fill the gaps in their knowledge o

Expert Blogs and Consumer Perceptions of Competing Brands

Social media-based expert blogs are a crucial and credible online information source for consumers, yet little is known about the role of expert blogs for general consumer brand perceptions that bestow long-term value for the firm. On the basis of a nove

Copycats vs. Original Mobile Apps: A Machine Learning Copycat-Detection Method and Empirical Analysis

While the growth of the mobile apps market has created significant market opportunities and economic incentives for mobile app developers to innovate, it has also inevitably invited other developers to create rip-offs. Practitioners and developers of original apps claim that copycats steal the original app's idea and potential demand, and have called for app platforms to take action against such copycats.

Social Network Effects on Productivity and Job Security: Evidence from the Adoption of a Social Networking Tool

By studying the change in employees' network positions before and after the introduction of a social networking tool, I find that information-rich networks (low in cohesion and rich in structural holes), enabled by social media, have a positive effect on various work outcomes.
