A central challenge to modern business cycle analysis is that standard macro models are unable to generate fluctuations in the stock market with the amplitude, persistence, and lead-lag pattern observed in the data. At the same time, standard macro models predict that good news about future, such as those received during 1994-1995 on the arrival of IT, lead to recessions rather than expansions. HBS professor Diego Comin and coauthors develop a model that overcomes these two problems by explicitly incorporating an endogenous speed of diffusion of technologies that is increasing in the resources spent in adoption. Revisions in beliefs about future profits generate fluctuations in the stock market with the amplitude and lead over output observed in the data. The firms' investment decisions in adoption leads to a shift in labor demand that increases hours worked and output.

The researchers argue that file-sharing technology has not undermined the incentives of artists and entertainment companies to create, market, and distribute new works. The advent of new technology has allowed consumers to copy music, books, video games, and other protected works on an unprecedented scale at minimal cost. Such technology has considerably weakened copyright protection, first of music and software and increasingly of movies, video games, and books. While policy discussion surrounding file-sharing has largely focused on the legality of the new technology and the question of whether declining sales in music are due to file-sharing, the debate has been overly narrow. Copyright protection exists to encourage innovation and the creation of new works—in other words, to promote social welfare. This essay analyzes the landscape and identifies areas for more research.

In spite of the cultural and social revolution in the rise of social networking sites such as Facebook and MySpace (and in South Korea, Cyworld), the business viability of these sites remains in question. While many sites are attempting to follow Google and generate revenues from advertising, will advertising be effective? If friends influence the purchases of a user in a social network, it could potentially be a significant source of revenue for the sites and their corporate sponsors. Using a unique data set from Cyworld, this study empirically assesses if friends indeed influence purchases. The answer: It depends. Findings are relevant for social networking sites and large advertisers.

Can patterns of corporate net stock issuance help identify times when particular characteristics, such as industry, size, or book-to-market ratio, are mispriced? The authors of this study argue that differences between the characteristics of issuers and repurchasers can shed light on characteristic related stock returns. Consider the case in which analysts were interested in forecasting the returns of Google. The standard approach would be to collect Google's characteristics (e.g., large, technology, non-dividend paying, etc) and associate these characteristics with an average return in the cross-section. The authors argue that if other stocks with these characteristics are issuing stock, this bodes poorly for Google's future returns, even if Google is itself not issuing. This research by HBS professor Robin Greenwood and Harvard doctoral student Samuel Hanson has implications for studying the stock market performance of seasoned equity offerings (SEOs), initial public offerings (IPOs), and recent acquirers.

To the extent that history is discussed at all in economic development, it is usually either the divergence associated with the Industrial Revolution or the effects of colonial regimes. Is it possible that precolonial, preindustrial history also matters significantly for today's national economic development? The authors find that technology adoption circa 1500 A.D., prior to the era of colonization and extensive European contacts, predicts approximately 50 percent of cross-country differences in both current per capita income and technology in a large cross-section of countries. When exploring the causes of this extreme persistence in technology, they find evidence in favor of the importance of the effect of current adoption on subsequent adoption as the main driver. This leaves a limited role to country-specific factors such as institutions, geography, or genes to explain the persistence of technology.

Why do established firms find some technological change so challenging? While existing research has identified numerous sources of inertia in established firms exploring new technological domains, identity is a critical piece of the puzzle. As the core essence of an organization, identity directs and constrains action. The routines, procedures, capabilities, knowledge base, and beliefs of an organization all reflect its identity. So when a technology is identity-challenging to an organization—when pursuing it would violate the core beliefs of both insiders and outsides about what the firm represents—organizations face significant obstacles to adopting it. This study by Tripsas highlights the importance of recognizing and evaluating the tradeoffs associated with technological opportunity and organizational identity.
Platform Rules: Multi-Sided Platforms as Regulators

Using case studies of Facebook, Tokyo's Roppongi Hills "mini-city," Harvard Business School, and TopCoder, a vendor of outsourced software products, Boudreau and Hagiu explore how multi-sided platforms (MSPs) regulate an industry ecosystem. An MSP is a platform that enables interactions between multiple groups of surrounding consumers and complementors. As the authors demonstrate, the regulatory role played in these cases by MSPs was pervasive and at the core of their business models. That regulatory role goes beyond price-setting and includes imposing rules and constraints, creating inducements, and generally shaping behaviors. These various non-price instruments essentially solve problems that could otherwise lead to market failure. The authors' analytical framework suggests a two-step approach for a platform owner: (1) maximize value created for the entire ecosystem, and (2) maximize the value extracted. "Platform Rules" is a chapter in the forthcoming book Platforms, Markets and Innovation, Gawer, A. (ed) (2009), Cheltenham, UK and Northampton, MA, U.S.: Edward Elgar.

The higher concentration of immigrants in certain cities and occupations has long been noted. There has been very little theoretical or empirical work to date, however, on the particular agglomeration of U.S. immigrant scientists and engineers. This scarcity is disappointing given the scale of these ethnic contributions and the importance of innovation to regional economic growth. William R. Kerr's study contributes to our empirical understanding of agglomeration and innovation by documenting patterns in the city-level agglomeration of ethnic inventors (e.g., Chinese, Indian) within the United States from 1975 through 2007. It is hoped that the empirical platform developed in this study provides a foothold for furthering such analyses.

Managers face a range of options to diffuse innovative practices within their organizations. This paper focuses on one such technique: providing practice-specific information through mechanisms such as internal seminars, demonstrations, knowledge management systems, and promotional brochures. In contrast to corporate mandates, this "information provision" approach empowers facility managers to decide which practices to actually implement. The authors examine how corporate managers diffused advanced environmental management practices within technology manufacturing firms in the United States. The study identifies several factors that encourage corporate managers to employ information provision, including subsidiaries' related expertise, the extent to which the subsidiaries were diversified or concentrated in similar businesses, and the geographic dispersion of their employees.

Keyword auctions have become a critical source of revenue for Google and Yahoo!, among others. This new form of advertising has provided a new way for advertisers to reach customers. But advertisers also face the complex task of optimizing bids to increase their exposure while avoiding unnecessary costs. HBS professor Benjamin Edelman and colleagues analyzed a class of bidding strategies that attempt to increase advertiser utility under limited assumptions about other players' behavior. Under a strategy they call Balanced Bidding (BB), advertisers converge to the advertiser-preferred equilibrium—achieving stability of bids and reducing advertisers' costs relative to other possible outcomes.

Established platform providers can be difficult to displace. This paper explores a path to platform leadership change that does not rely on breakthrough innovation or Schumpeterian creative destruction: a phenomenon the authors call "platform envelopment." In practical terms, envelopment entails one platform provider adding another platform's functionality to its own, and then offering a multiplatform bundle. Eisenmann and his colleagues describe a variety of envelopment attacks based on the relationship between the attacker's platform and its target's, and then discuss the economic and strategic motivations for each attack type.

The term "platform" is increasingly popular among executives today. Platforms, and multi-sided platforms (MSPs) in particular, serve the needs of interdependent constituents. Although MSPs have existed for centuries in the form of matchmakers and village markets, information technology has increased tremendously the opportunities for building larger, more powerful, and more valuable platforms. At the same time, by expanding the potential scope of platforms, information technology has also increased the number and complexity of factors, both economic and technical, that drive the strategic design of MSPs. Surprisingly, few companies rigorously analyze the underlying drivers of their MSPs, and the emerging business and economics literature on two-sided markets has not been very helpful in this direction, either. This article provides a general framework to help organize managerial thinking about MSPs.

With ever more sophisticated logistics and the rise of information technologies, intermediaries and market platforms have become increasingly ubiquitous and important agents in the digital economy. While market intermediation is not a new phenomenon, the digital economy has revealed that there can be two polar types of intermediaries: "merchants," which acquire goods from sellers and resell them to buyers, and "two-sided platforms," which allow affiliated sellers to sell directly to affiliated buyers. As examples, retailers like Walmart.com and Amazon.com are (mostly) merchants; eBay is a pure two-sided platform; and Apple's iTunes digital music store exhibits both merchant and platform features. This research is a first pass at delineating the economic tradeoffs between the merchant and two-sided platform modes.

Scholars have long been interested in the impact of information technology on the organization of work. As Andrew McAfee and colleagues argue in this study, the appropriate governance mechanism for an IT-facilitated collaboration depends on the type of IT being deployed: When an enterprise technology is required, so is an electronic hierarchy. The paper explores the issue of relationship specificity of IT assets, proposes a categorization of information technologies based on their levels of relationship specificity, and uses data from more than forty Italian industrial districts to test three hypotheses around governance of interfirm IT. These districts typically have close ties, both horizontal and vertical, and have historically worked in close collaboration with each other.
