In markets with network effects, the value that users gain from platforms depends on the number of other users of the same type who join the same platform (direct network effects) or the number of users of a different type that join (cross-group network effects). Examples include social networks like Facebook or Google+, payment systems like PayPal or Visa, videogame systems like PlayStation 3 and Xbox 360, smartphone platforms like Apple's iPhone or Google's Android, etc. Users typically rely on the media, market reports, or word of mouth to form expectations about the total number of other users that join a given platform. However, most of the time these users are unable to calculate the effect of platforms' prices on adoption by other users. In other words, they do not take price into account when forming expectations. To analyze platform profits, Andrei Hagiu and Hanna Hałaburda model different degrees of user sophistication in forming price expectations in markets with network effects. They show that firms have different preferences regarding the average sophistication of their user base depending on market structure.

The mere fact that an online video advertisement reaches a viewer's computer screen does not guarantee that the ad actually reaches the viewer. New experimental research by Thales S. Teixeira looks at how advertisers can effectively capture and keep viewers' attention by evoking certain emotional responses.
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.
Why are the U.S. News and World Report College Rankings so influential? According to this paper by Michael Luca and Jonathan Smith, it's at least in part because U.S. News makes the information so simple. While earlier college guides had already provided useful information about schools, U.S. News did the work of aggregating the information into an easy-to-use ranking, making it more salient for prospective students. The authors show that these rankings matter in a big way: a one-rank improvement leads to a 0.9 percent increase in applicants. However, students tend to ignore the underlying details even though these details carry more information than the overall rank.
Retailers, search engines, shopping malls and other intermediaries often deliberately design their physical layouts or e-commerce sites in order to divert customers' attention away from the products they were initially looking for, with hopes that they'll buy a bunch of other products, too. This paper explores various incentives for so-called "search diversion" in a couple of scenarios—when stores internalize their affiliation decisions with intermediaries, and when competition is introduced among intermediaries. Research was conducted by Andrei Hagiu of Harvard Business School and Bruno Jullien of the Toulouse School of Economics.
Companies offering top-drawer customer service might have a nasty surprise awaiting them when a new competitor comes to town. Their best customers might be the first to defect. Research by Harvard Business School's Ryan W. Buell, Dennis Campbell, and Frances X. Frei.
Economists love menus, which can be used to help understand people's choices. For example, do we prefer more choices (larger menu) or fewer (shorter menu)? But the menu itself has to be pre-selected. Research by David Goldreich (Rotman School of Management, University of Toronto) and Hanna Halaburda (Harvard Business School) focuses on the menu setter's decisions about what to include, and how large a menu to construct in the context of 401(k) plan choices.
Companies increasingly involve customers in the design and assembly of products, from Converse allowing customers to design their own shoes to IKEA asking customers to assemble their own furniture. In this paper researchers Michael I. Norton (Harvard Business School), Daniel Mochon (University of California at San Diego), and Dan Ariely (Duke) use the "IKEA Effect" to explain the increase in valuation we place on products we build ourselves. The researchers discuss the implications of the IKEA Effect for marketing managers and organizations more generally.
Many cities encourage residents to sort their domestic trash into separate bins, for the sake of recycling some of it and thus reducing the amount of garbage that ends up in landfills. The problem is that sorting waste is not a fun activity, and not everyone is willing to do it. Using data from 95 municipalities in Italy, this paper discusses whether and how monetary incentives can encourage people to sort their trash. Research was conducted by Alessandro Bucciol of the University of Verona and the University of Amsterdam, Natalia Montinari of the University of Padua and the Max Planck Institute of Economics, and Marco Piovesan of Harvard Business School.
Companies that compete by offering a high level of service are particularly vulnerable to lose customers—even longtime customers—when competitive entrants offer increased service levels, according to new research in the retail banking industry by Ryan W. Buell, Dennis Campbell, and Frances X. Frei, all of Harvard Business School. The good news for providers of high-touch service is that if they can sustain the service advantage over time, they could be rewarded with higher value customers.
In the course of making a decision, managers often err in one of two directions—either overanalyzing a situation or forgoing all the relevant information and simply going with their gut. HBS marketing professor Michael I. Norton discusses the potential pitfalls of thinking too much or thinking too little.
Depositors are overconfident of their chances of recovering demandable deposits in a bank run. In a recent research paper, professor Julio J.

Firms entering a new product market face tremendous ambiguity and competitive uncertainty, particularly when the new market is sparked by radical technological change. Potential customers have little or no experience with products, and during this period of turbulence, firms experiment with alternative product configurations, functions, and technologies. By studying the emergence of the consumer mass market for digital cameras, Carlson School of Management professor Mary J. Benner and HBS professor Mary Tripsas explore what factors influence a firm's initial introduction of product features during the nascent stage of a product market, and how the process of convergence on a standard set of features unfolds. In particular, they assess how a firm's prior industry affiliation influences its conceptualization of the product.
Why do platforms that restrict choice and charge higher prices seem to prosper alongside platforms offering cheap or free unlimited choice? In the online dating market, for example, eHarmony deliberately limits the number of candidates available to its customers. Headhunters show only a few candidates to the companies, and even fewer companies to the candidates. In the housing market, brokers limit the number of houses they show to potential buyers and sellers. In this paper, HBS professors Hanna Halaburda and Mikolaj Jan Piskorski challenge conventional understanding of platform competition and network effects by describing a two-sided matching environment and studying the indirect network effects in this environment. They show that the interplay between more choice and more competition influences the strength of network effects and attractiveness of a platform. Some agents may opt for a platform with few choices to avoid higher levels of competition. The researchers' model helps explain why platforms that limit their choice set coexist (and thrive) alongside platforms that offer greater choice.

Despite an increased standard of living in the United States and other developed countries, health problems attributable to poor nutrition persist in part due to consumers' inability to translate the dietary advice of nutrition experts into anything actionable. Citing the improvement of public health as a primary objective, numerous studies have highlighted the need for a nutritional scoring system that is both comprehensive in its coverage of food products and easily understood by consumers. In this paper the researchers advance this objective by proposing a nutrition metric that is based on the current views of leading experts in the field. The metric can be used to score any food or beverage for which several component nutrient quantities are known.

Discount membership clubs have a large and growing presence in retail—one recent survey reported that Costco sells to 1 in every 11 people in the United States and Canada, and warehouse clubs are estimated to be a $120 billion industry today in the United States alone. As a result, many people have had the experience of entering one of these popular clubs and leaving hours later with more goods than can fit in their car. One rational reason for such behavior is that membership clubs do offer lower prices than other retailers. However, Norton and Lee offer a counterintuitive explanation for such buying behavior. They propose that the presence of membership fees alone—independent of the actual savings on any given product—can lead consumers to infer a "fees → savings" link, leading them to spend more than they otherwise would to capitalize on these perceived "great deals." Norton and Lee explore this phenomenon by setting up their own "membership clubs" and comparing profits across stores with varying membership fees.

Pizza or salad? Consumers use different approaches to buying things they want (pizza) versus items they should buy (salad). In their research on online grocery-buying habits and DVD rentals, Harvard Business School's Katy Milkman and Todd Rogers, along with Professor Max Bazerman, provide insights on the want-should conflict and the implications for managers in areas such as demand forecasting, consumer spending habits, and effective store layout.
When can variety be helpful and when can it be harmful? Conventional wisdom suggests that a product provider enhances the overall attractiveness of a set of options by adding more alternatives to the mix. By contrast, Gourville and Soman's research indicates that in certain, predictable cases, adding more alternatives to an assortment leads consumers to choose either the most basic or the most "fully loaded" product or service, be it a camera, car, cable TV service, laptop, or vacation package in Italy.
Brazilian retailer Magazine Luiza has developed an innovative strategy for selling to the poor, combining technology with great service that please both customers and employees.

Frei.
Consider a retailer who operates both brick-and-mortar stores and direct channels such as direct mail catalogs and an Internet Web site. What effect does the opening of a new retail store have on direct channel sales in the retail trading area surrounding the store? Does the existence of more opportunities for consumer contact with the brand increase the retailer's direct sales, or does intra-brand, inter-channel competition erode the retailer's direct sales? Does consumer response to the retailer's brand evolve over time, perhaps as consumers go through some process of trial-and-error learning about the relative merits of stores and direct channels, or is the impact of the new store relatively discrete? Does the answer depend on whether consumers in the retail trading area have had the opportunity for previous experience with the brand's stores? This research used a proprietary longitudinal dataset from a multichannel retailer to understand what happens and to probe the implications for channel management strategy.
The growing use of MRI (magnetic resonance imaging) devices for studying decision making means that in 2007 we may hear a number of striking conclusions based on studies involving a small number of brain scans, says Jim Heskett.

"Partitioned" price tags that include a main price plus additional charges (Lamp: $70, Bulb, $5, Shipping: $15) may be confusing your customers at best or even causing them to reject the product, warns HBS professor Luc Wathieu. When is an all-inclusive price the best bet?
The "Long Tail," a term coined by Chris Anderson—and the title of his new book—describes the item popularity curve. Does the Long Tail represent a paradigm shift for business and consumer behavior? What are its implications for management going forward?
How do consumers evaluate different pricing scenarios? This study looks at different pricing models to see which is more likely to result in positive customer perception. Specifically, the authors look at all-inclusive pricing (e.g., the price of a chair is $85.95 including shipping) versus partitioned pricing (e.g., the price of a chair is $81 and shipping is $4.95). When consumers are presented with a partitioned price, they place an exaggerated weight on their evaluation of each individual component.
People who buy retail prescription drugs, invest funds, or participate in auctions rarely have complete information about the product they are buying. Often the only auction information participants have is the number of bidders, observed bids, and product characteristics. If data from an auction, for instance, is a function of bidder behavior, then external survey data may help in testing hypotheses about bidding behavior. Researchers often avoid using surveys because they consume time and effort, but Yin presents a survey design technique and econometric tool to deal with a general population of survey respondents. Her application tested eBay online auctions selling personal computers.
How can auctions be used most effectively? Government and industry traditionally use auctions to price and allocate assets and contracts with high but unknown value. Millions of people use Internet auctions for goods that are often of unknown value (e.g., used goods, unknown brands). This paper asks: Do bidders behave in the way auction theory predicts they should? And, what are the effects of different types of information on prices? To answer these questions, Yin combined theory, econometric modeling, and survey data.
While neither buyers nor sellers may be certain of the worth of used goods, both may possess private information about the value. Do prices become more informative as the number of bidders grows? Using data from a sample of eBay auctions for computers, Yin looked at how and under what conditions auction prices converge to the common value of a given item.

This paper is about discrete-choice and econometric models. The "invariant proportion of substitution," or IPS, property comes into play when, for example, a consumer faces a choice among three laptop computers with slightly different attributes. How will improvements to one laptop's attributes affect how the consumer chooses to substitute one alternative for another? Steenburgh looked at probabilities based on assumptions about consumers' utility-maximizing behavior.
In the past, we knew a lot about the seller of a product (through ads, marketing, or reputation) but little about the individual buyer. Times have changed. From the Internet to store loyalty cards, technology has made the marketplace into an interactive exchange where the buyer is no longer anonymous. The future market will likely be one in which personal information is shared and leveraged. Consumers who are willing to share their information will be more attractive to sellers and more sought-after than those who have bad reputations or refuse to participate.
