Reviews, Reputation, and Revenue: The Case of Yelp.com

In just six years, Yelp.com has managed to crowdsource 20 million reviews of restaurants and other services by creating and leveraging an impressive social network of people who enjoy writing reviews. But can a bunch of amateur opinionators working for free really transform the restaurant industry, where heavily marketed chains and highly regarded professional critics have long had a stronghold? To answer this question, HBS professor Michael Luca combined Yelp reviews with revenues for every restaurant that operated in Seattle, WA at any point between 2003 and 2009. Applying a new method to tease out the causal effect of reviews (separate from the effect of underlying quality), the study shows that a one-star increase on Yelp leads to a 5 to 9 percent increase in revenue. Yet Yelp doesn't work for all restaurants. Chain restaurants —which already spend heavily on branding —are unaffected by changes in their Yelp ratings. This suggests that consumer reviews present a new way of learning in the Internet age, and are fast becoming a substitute for traditional forms of reputation.

About 95 percent of new products fail. The problem often is that their creators are using an ineffective market segmentation mechanism, according to HBS professor Clayton Christensen. It's time for companies to look at products the way customers do: as a way to get a job done.

To what extent do balanced scorecards provide useful information for testing and validating an organization's strategy? Numerous case studies of balanced scorecard implementations document their use in translating organizational strategies to objectives and measures, communicating strategic objectives to employees, evaluating the performance of business units, and aligning the incentives of employees across business units and functions. There has been comparatively little research, however, on the potential learning and feedback role of balanced scorecards. Analyzing balanced scorecard data from Store24—a privately held convenience store retailer in New England—during the implementation of an innovative but ultimately unsuccessful strategy, this study investigates whether, when, and how information about problems with the firm's strategy was captured in the multiple performance measures of its balanced scorecard.
Organizational Design and Control across Multiple Markets: The Case of Franchising in the Convenience Store Industry

Chain organizations operate units that are typically dispersed across different types of markets, and thus serve significantly different customer bases. Such "market-type dispersion" is likely to compromise the headquarters' ability to control its stores for two reasons: Relative differences in local conditions make it difficult to monitor a store manager's behavior, and a chain with wide-ranging customer bases will have a harder time serving its customers and will need to rely more heavily on store managers' ability to adapt to local needs. This study identifies market-type dispersion as a factor that is systematically related to firms' organizational design choices. The results may help managers and consultants who deal with control challenges related to a chain's geographic expansion into different markets.
Finding Missing Markets (and a disturbing epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya

Why do farmers continue to grow crops for local markets when crops for export markets are thought to be much more profitable? Answers may include missing information about the profitability of these crops, lack of access to the necessary capital to make the switch possible, lack of infrastructure necessary to bring the crops to export outlets, high risk of the export markets, lack of human capital necessary to adopt successfully a new agricultural technology, and misperception by researchers and policymakers about the true profit opportunities and risk of crops grown for export markets. Ashraf and colleagues conducted an experimental trial with DrumNet, a social enterprise of Pride Africa, a nongovernmental organization, to evaluate whether a package of services can help farmers adopt, finance, and market export crops, and thus earn more income. This experiment was motivated by a recent push in development to build sustainable interventions that help complete missing markets.

I'll Have the Ice Cream Soon and the Vegetables Later: Decreasing Impatience over Time in Online Grocery Orders

How do people's preferences differ when they make choices for the near term versus the more distant future? Providing evidence from a field study of an online grocer, this research shows that people act as if they will be increasingly virtuous the further into the future they project. Researchers examined how the length of delay between when an online grocery order is completed and when it is delivered affects what consumers order. They find that consumers purchase more "should" (healthy) groceries such as vegetables and less "want" (unhealthy) groceries such as ice cream the greater the delay between order completion and order delivery. The results have implications for public policy, supply chain managers, and models of time discounting.
