The emergence of a giant cluster, in which bits and pieces of otherwise unconnected parts of a system come together, has been extensively studied in nonsocial contexts. This phenomenon has attracted substantial attention because it allows researchers to understand and predict the collective...

News consumers in many authoritarian countries read government-controlled sources even when independent sources are available. We test whether these choices reflect a preference for pro-government coverage versus persistent tastes for specific websites. We exploit textual data from news...

Product personalization opens the door to price discrimination. A rich product line allows for higher consumer satisfaction, but the mere choice of a product carries valuable information about the consumer that the firm can leverage for price discrimination. Controlling the degree of product...

Quality certification programs are used to improve consumers’ ability to identify high-quality products or sellers in markets with information asymmetries. Using data from eBay UK’s online marketplace, we study how certification’s benefits vary with market- and seller-level attributes,...

This paper provides theory and evidence about how vertical collaboration between an integrated firm and a focused supplier enhances the market performance of knowledge-based products. We posit that, when downstream commercialization is concentrated relative to upstream product development,...

This paper develops an analytically coherent yet parsimonious framework which explains market returns in terms of contemporaneous information. It anchors on the idea that valuation (static perspective) can be connected to the dynamics that explains returns, and vice versa. The framework requires...

Around the start of this new millennium, scholars in the operations management/operations research field started to make important contributions to the study of price competition models. In this tutorial, we review these contributions, and partition them into five broad areas. Most of the...

This paper summarizes the display advertising literature, organizing the content by the agents in the display advertising ecosystem, and proposes new research directions. In doing so, we take an interdisciplinary view, drawing connections among diverse streams of theoretical and empirical...

We find significant positive abnormal returns surrounding a surprising and quick enactment of a law that restricts executive pay to a binding upper limit in a few industries. We find that the effect is concentrated only for firms in which the restriction is binding. We also find that the...

Abstract Staffing decisions typically account for a large portion of a retailer's operational costs. The effectiveness of these decisions has often been analyzed by relating staffing levels to revenues. However, such approach does not explicitly consider the mechanisms by which the staff can...
