Incompatible Assumptions: Barriers to Producing Multidisciplinary Knowledge in Communities of Scholarship
Just as flows of knowledge within and across communities of practice improve the quality of new products, knowledge sharing among knowledge workers within interdisciplinary communities may be critical for new discoveries and for a more comprehensive and accurate understanding of phenomena. In spite of this, biologists tend to talk to biologists, economists tend to talk to economists, and lawyers tend to talk to lawyers. This paper argues that producing and disseminating knowledge within a multidisciplinary community of practice is enhanced when knowledge workers hold compatible assumptions, even when the form and content of knowledge generation across those workers varies. Key concepts include: Generating multidisciplinary knowledge may require communities of scholarship to acknowledge the presence and limitations of their assumptions. Within a community of scholarship, interpretive barriers to sharing knowledge arise when subgroups hold contrary assumptions about the appropriate questions to be asked or the fundamental nature of the phenomenon under investigation. Cross-discipline understanding may stem from the potential for members to recognize the relevance of others' findings to their own scholarship. Closed for comment; 0 Comments.

Optimal Deterrence when Judgment-Proof Agents Are Paid In Arrears—With an Application to Online Advertising Fraud
It is commonplace for large entities (both advertisers and ad networks) to enter into relationships with numerous small agents such as Web sites, blogs, search syndicators, and other marketing partners. For example, one well-known affiliate network boasts more than a million affiliates promoting offers from the network's hundreds of merchants, and Google contracts with numerous independent Web sites to show Google's "AdSense" ads. Although these advertising agents are often small, they can take advantage of technology to claim payments they have not earned. In practice, the legal system cannot offer meaningful redress to an aggrieved advertiser or ad network. This paper argues that delayed payment offers a more expedient alternative—a sensible stopgap strategy for use when primary enforcement systems prove inadequate. Key concepts include: Online advertising markets are one of many markets where agents may be effectively unreachable through the legal system. Online advertising contracts presently lack any institution by which the payment structure can enforce good practices. Improving detection technology remains the preferred deterrent of online advertising fraud. Appropriate selection of a payment delay can achieve the benefits offered by contingent payment in other markets. Closed for comment; 0 Comments.

Sell Side School Ties
Certain agents play key roles in revealing information into securities markets. In the equities market, security analysts are among the most important. A large part of an analyst's job (perhaps the majority) is to research, produce, and disclose reports forecasting aspects of companies' future prospects, and to translate their forecasts into stock recommendations. Therefore, isolating how, or from whom, analysts obtain the information they use to produce their recommendations is important. Do analysts gain comparative information advantages through their social networks—specifically, their educational ties with senior officers and board members of firms that they cover? This paper investigates ties between sell-side analysts and management of public firms, and the subsequent performance of their stock recommendations. Key concepts include: Equity analysts outperform on their stock recommendations when they have an educational link to that company. A simple portfolio strategy of going long the buy recommendations of analysts with school ties and going short the buy recommendations of analysts without ties earns returns of 5.40% per year in the full sample. Informal information networks are an important, yet under-emphasized channel through which private information gets revealed into prices. Closed for comment; 0 Comments.

Modeling Expert Opinions on Food Healthiness: A Nutrition Metric
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. Key concepts include: This model encompasses the factors that matter most to the professional judgment of nutrition experts. Previous models focusing solely on either positive or negative nutrients have omitted critical information that experts take into account when assessing a food's healthiness. This model could be used to generate healthiness ratings that are displayed on or near food and beverage labels, allowing consumers to make more informed choices about which products to purchase and consume.

An Investigation of Earnings Management through Marketing Actions
Earnings management behavior may be divided into two categories: 1) the opportunistic exercise of accounting discretion; and 2) the opportunistic structuring of real transactions. This paper focuses on the latter by providing evidence that managers use retail-level marketing actions (price discounts, feature advertisements, and aisle displays) to influence the timing of consumers' purchases in relation to their firms' fiscal calendars and financial performance. The results will be of interest to practitioners negotiating with suppliers as well as those responsible for setting price and promotion strategy in response to competitor actions, and practitioners responsible for designing incentive-based compensation as well as regulators monitoring reporting of fiscal period-ending promotion. Key concepts include: Marketing actions that produce short-term results occur more frequently when firms have incentive to manage reported earnings upwards. While these actions boost unit sales, revenue, and profits in the near term, the resulting gains come at the expense of long-term profit and may not be in the strategic interest of the firm. These results imply that firms make systematic decisions across their product lines to manage earnings and indicate the behavior is being driven by parties higher in the firm than the brand managers.

Allocating Marketing Resources
Deciding how to allocate marketing resources is particularly difficult because decisions need to be made at many different levels—across countries, products, marketing mix elements, and different vehicles within elements of the mix (e.g., television versus the Internet for advertising). With the increasing availability of data and sophistication in methods, it is now possible to more judiciously allocate marketing resources. In this paper, HBS professors Gupta and Steenburgh discuss a two-stage process where a model of demand is estimated in stage-one and its estimates are used as inputs in an optimization model in stage-two. The researchers propose a matrix with three approaches for each of these two stages, and discuss the pros and cons of these methods. They highlight each method with applications and case studies to present rigorous yet practical approaches to making marketing resource allocation decisions. Key concepts include: This paper lays out a framework for managers who are responsible for allocating marketing resources for their products and services. Scores of studies in the area of allocating marketing resources now make it possible to form empirical generalizations about the impact of marketing actions on sales and profits. In practical terms, information about marketing resource allocation makes a significant impact at all levels of an organization. Closed for comment; 0 Comments.

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. Key concepts include: Researchers found positive but not overwhelming one-year impacts from DrumNet. DrumNet leads to more farmers growing export crops, increasing their production and lowering their marketing costs. While there was no statistically significant impact on income for the full sample of farmers, first-time growers of export-oriented crops experienced a statistically and economically significant increase in income. The epilogue to this project is more dismal. Due to DrumNet's lack of compliance with European export requirements, farmers were forced to undersell and thus default on their loans. The implication is that farmers may not be adopting export crops because of the risk of the export market. Closed for comment; 0 Comments.

Board of Directors’ Responsiveness to Shareholders: Evidence from Shareholder Proposals
How well do boards of directors respond to shareholder concerns? The recent wave of corporate scandals has raised questions about the effectiveness of boards in their monitoring role. The subsequent reform debate focused on enhancing boards' independence from management, increasing their accountability to shareholders through a different board election system, and improving boards' internal processes and practices. One direct example of this alleged lack of responsiveness to shareholder concerns is the historically low frequency of adoption of non-binding shareholder proposals receiving a majority vote, even when the vote is overwhelmingly in favor of the proposal and has been repeated for a number of years. Ignoring majority-vote shareholder proposals may be increasingly expensive, however, both for the targeted firms and for the individual directors. HBS professor Ferri and coauthors analyze the frequency of implementation of non-binding, majority-vote shareholder proposals and examine the determinants and consequences of the boards' implementation decisions. Key concepts include: A dramatic increase in the frequency of implementation of non-binding, majority-vote shareholder proposals is consistent with a structural shift in the governance environment and assertions of a new atmosphere in boardrooms. The likelihood of implementation of majority-vote shareholder proposals is higher when shareholder pressure and peer pressure are stronger. Firms whose peers recently implemented a similar majority-vote shareholder proposal are more likely to follow suit. Outside directors implementing a majority-vote shareholder proposal are more likely to retain their board seat and to experience gains (or lower losses) in other directorships.

Testing a Purportedly More Learnable Auction Mechanism
Each year, auctions are used to determine how billions of dollars of goods and services will be allocated across the globe. On eBay alone, $52.5 billion in merchandise was exchanged in 2.4 billion auctions conducted during fiscal year 2006. Considerable attention has been paid in the academic literature to the question of how to design auctions with efficient allocation and revenue-maximizing properties. However, in part because auction rules are typically published and standard theory assumes economic agents are capable of computing optimal strategies from published rules, little attention has been paid to the question of how to design auctions whose optimal strategies are easy to learn. Evidence suggests that even when auction rules are published and dominant strategies exist, people nonetheless struggle and sometimes fail to learn to play their optimal strategy. As a result, the authors argue that the question of how to design a learnable, strategy-proof auction mechanism is an important one. Key concepts include: Designers of auction mechanisms should create mechanisms that are easier for people to learn. This paper describes an auction mechanism that has received attention in the computer science literature because of its theoretical property of being more learnable than the standard mechanism. In fact, the new mechanism produced slower learning in human subjects than the standard mechanism. Closed for comment; 0 Comments.

Colonial Land Tenure, Electoral Competition and Public Goods in India
How is the impact of historical institutions felt today? This comparative analysis by Banerjee and Iyer highlights the impact of a specific historical institution on long-term development, specifically the land tenure systems instituted during British colonial rule. The paper compares the long-term development outcomes between areas where controls rights in land were historically given to a few landlords and areas where such rights were more broadly distributed. The paper also documents the impact of these differing historical institutions on political participation and electoral competition in the post-colonial period. Key concepts include: There are large differences in the development trajectories of areas that had different land tenure systems under British colonial rule. In particular, areas that were put under the control of landlords lag behind in the provision of public goods such as schools and roads compared with areas in which control rights in land were given to small cultivators. These differences are discernible even four decades after the end of colonial rule, and three decades after the landlord-based land tenure systems were officially abolished. Political participation and literacy levels are lower in landlord areas, but these differences are not sufficient to explain the differences in public goods provision. Closed for comment; 0 Comments.

Long-Run Stockholder Consumption Risk and Asset Returns
The long-run consumption risk of households that hold financial assets is particularly relevant for asset pricing. The fact that stockholders are more sensitive to aggregate consumption movements helps explain why the consumption risk of stockholders delivers lower risk aversion estimates. Understanding further why consumption growth, particularly that of stockholders, responds slowly to news in asset returns will improve finance scholars' understanding of what drives these long-run relations. HBS professor Malloy and his coauthors examine more disaggregated measures of long-run consumption risks across stockholders and non-stockholders, and provide new evidence on the long-run properties of consumption growth and its importance for asset pricing. Key concepts include: Small and value stocks earn low returns, and long-term bonds do poorly when the future consumption growth of stockholders is low. The high average returns observed for small and value stocks and long-maturity bonds may therefore reflect the premium stockholders require to bear long-run consumption risk.

Consumer Demand for Prize-Linked Savings: A Preliminary Analysis
Prize-linked savings (PLS) products are savings vehicles that may appeal to people with little savings and little interest in traditional savings products. PLS products offer savers a return in the form of the chance to earn large prizes, rather than in more traditional forms of interest or dividend income or capital appreciation. The probability of winning is typically determined by account balances, and the aggregate prize pool can be set to deliver market returns to all savers. Prize-linked assets are offered in over twenty countries around the world—including the U.K., Sweden, South Africa, and many Latin American and Middle Eastern countries—but are not available in the United States, where state laws and federal regulations make the offering of prize-linked programs problematic. This working paper provides a first look into demand for a PLS product in the United States. Key concepts include: PLS products are promising, despite formidable barriers to success in the United States. The low income population that was studied expressed substantial interest in a savings product that provides prizes as part of its return. This product appeals to non-savers, who do not save with traditional products. The product appeals to heavy lottery players, and by virtue of this fact, has the potential of turning their gambling activities into demand for savings. PLS products might face an uphill battle in the United States due significantly to well-established gambling and lottery industries that might oppose PLS, and the roadblocks due to legal uncertainty and prohibitions around this new product. Businesses or state treasurers might be reluctant to innovate around a product that must compete against heavily marketed alternatives. Closed for comment; 0 Comments.

Do Legal Origins Have Persistent Effects Over Time? A Look at Law and Finance around the World c. 1900
A significant number of recent papers find legal origins to be strongly correlated with current indices of rule of law, financial development, the regulation of entry and labor, and the concentration of ownership, among other things. Few studies, however, have explored whether correlations between institutions and economic and financial outcomes hold in the past. For this reason, we cannot be certain that the alleged persistence of the effects of these institutions passes the scrutiny of history. This paper examines specifically the relationship between legal origins and financial development by analyzing countries' legal traditions and the extent of investor protections and financial development over time. Key concepts include: Circa 1910, the protection of shareholders did not rely strongly on government or court enforcement of shareholder rights. In many countries, companies reliant on outside financing had to win investor trust by either building good reputations or writing strong protections for small shareholders into their company bylaws. The findings of this paper do not imply that legal origin cannot be a significant explanatory variable of the differences observed in financial development today. Instead, they suggest a need for more research into how shocks of the 20th century triggered a political process that led to state intervention and regulation, which ended up making legal origin matter more.

Embracing Commitment and Performance: CEOs and Practices Used to Manage Paradox
How do chief executives establish strategic practices around their visions and intents? How do such practices make it possible to create both high commitment and high performance? The central puzzle for HBS professor emeritus Michael Beer and colleagues is not the creation of high commitment per se, but the kind of commitment that is useful for the implementation of strategy and sustainable performance. Beer et al. sought out major companies in North America and Europe that had a history of sustainable, above-average financial performance, and where there were indications of the companies being high-commitment organizations. They then conducted in-depth interviews with 26 CEOs of such companies, asking about activities and practices that help create commitment and performance. Key concepts include: The CEOs did not frame choices as "either-or" but rather "both-and." They argued that seemingly conflicting outcomes cannot be made the subject of choice, nor can they be balanced. It is the role of a CEO to embrace paradoxes and at least at the espoused level try to reconcile them. The research team found 5 groups of interrelated managerial practices that characterize this kind of strategic management. The practices engage employees emotionally and rationally, and facilitate strategic change, rather than implement it top-down. Closed for comment; 0 Comments.

Laws vs. Contracts: Legal Origins, Shareholder Protections, and Ownership Concentration in Brazil, 1890-1950
The early development of large multidivisional corporations in Latin America required much more than capable managers, new technologies, and large markets. Behind such corporations was a market for capital in which entrepreneurs had to attract investors to buy either debt or equity. This paper examines the investor protections included in corporate bylaws that enabled corporations in Brazil to attract investors in large numbers, thus generating a relatively low concentration of ownership and control in large firms before 1910. The case of Brazil is particularly interesting because, in Latin America before World War I, it boasted the second-largest equity market and largest number of traded companies. As HBS professor Aldo Musacchio shows, the considerable variation of investor protections over time at the country level, and even at the company level, urges cautions against notions about the persistency of institutions, especially of legal traditions. Key concepts include: Many large Brazilian corporations at the turn of the 20th century induced small investors to buy equity by choosing bylaws that distributed power in a more democratic way among shareholders. Maximum vote provisions, and to a lesser degree graduated voting scales, were correlated with lower concentration of ownership and voting power. The shareholder protections in national laws that seem to have mattered most were those that facilitated the private monitoring of corporate activities by requiring corporations to publish important financial information. It is possible for companies to break with the institutional environment in which they operate. It is unlikely that the institutions relevant to the expansion of equity markets and development of large multidivisional corporations were determined hundreds of years ago, either at the time of colonization or when countries adopted their current legal systems.

Unconventional Insights for Managing Stakeholder Trust
Most organizations understand the need to manage stakeholder trust. The bad news: Most organizations don't really understand how to manage the difficult job effectively. However, for those companies wishing to reap the benefits of improved cooperation with suppliers, increased motivation and productivity among employees, enhanced loyalty among customers, and higher levels of support from investors, managing stakeholder trust is a prudent, if not critical investment. Trust management may require an appreciation for some unconventional insights regarding the appropriate investment of resources. Stakeholders differ in regard to the kinds and degrees of vulnerability they face; what they need to believe before they will trust also differs. Would-be trust managers will be wise to consider these varying needs and to anticipate the tradeoffs that exist in strengthening relationships with specific stakeholders. Key concepts include: Trust is multidimensional, and it is not obvious which dimension you need to focus on when dealing with any particular stakeholder group. Stakeholder groups have different needs and vulnerabilities. Efforts aimed at solving one trust problem can exacerbate others. Stakeholders of all types are interested in associating with organizations with whom they can identify, and with whom they perceive a match in values. Closed for comment; 0 Comments.

The Small World of Investing: Board Connections and Mutual Fund Returns
How does information flow in security markets, and how do investors receive information? In the context of information flow, social networks allow a piece of information to flow along a network often in predictable paths. HBS professors Lauren Cohen and Christopher Malloy, along with University of Chicago colleague Andrea Frazzini, studied a type of dissemination through social networks tied to educational institutions, examining the information flow between mutual fund portfolio managers and senior officers of publicly traded companies. They then tested predictions on the portfolio allocations and returns earned by mutual fund managers on securities within and outside their networks. Key concepts include: Social networks are important for information flow between firms and investors. Across the spectrum of U.S. mutual fund portfolio managers, fund managers place larger concentrated bets on stocks they are connected to through their education network, and do significantly better on these holdings relative to non-connected holdings, and relative to connected firms they choose not to hold. A portfolio of connected stocks held by managers outperforms non-connected stocks by up to 8.4 percent per year. This connection is not driven by firm, fund, school, industry, or geographic location effects, nor by a subset of the school connections (e.g., Ivy League). The bulk of this premium occurs around corporate news events such as earnings announcements. This finding suggests that the excess return earned on connected stocks is driven by information flowing through the network. As the information will eventually be revealed into stock prices, advance knowledge implies return predictability. Closed for comment; 0 Comments.

Psychological Influence in Negotiation: An Introduction Long Overdue
This paper attempts to encourage a better dialogue between research on social influence and on negotiation. It provides an overview of the literature on both areas, and identifies opportunities for creating more effective and useful research. First, HBS professors Deepak Malhotra and Max Bazerman identify those elements of psychological influence that do not require the influencer to change the economic or structural aspects of the bargaining situation in order to persuade the target. Second, they review prior research on behavioral decision-making in negotiation to identify those ideas that may be relevant to influence in negotiation. Third, they provide a framework for thinking about how to leverage behavioral decision research to wield influence in negotiation. Fourth, they consider how targets of influence might defend against these tactics. Fifth, because psychological influence is, by definition, aimed at achieving one's own ends through the strategic manipulation of another's judgment, they consider the ethical issues surrounding its application in negotiation. Key concepts include: A broader research field of negotiation is needed, one that more closely matches real-world views of what negotiation entails. This paper conceptualizes and organizes a new domain of academic inquiry—psychological influence in negotiation—contrasting it with literature on social influence. The last 50 years of research on social influence has focused largely on economic and structural elements of influence. However, psychological influence is an interesting and important domain of study in its own right, and is very relevant to the field of negotiation research. Closed for comment; 0 Comments.

Attracting Flows by Attracting Big Clients: Conflicts of Interest and Mutual Fund Portfolio Choice
Retirement assets make up a large and growing percentage of the mutual fund universe. In 2004, nearly 40 percent of all mutual fund assets were held by defined contribution plans and individual retirement accounts. This percentage is steadily increasing largely because these retirement accounts represent the majority of new flows into non-money market mutual funds. With such a large and growing percentage of their assets coming from retirement accounts, mutual funds are likely to be interested in securing these big clients. This paper examines a new channel through which mutual fund families can attract assets: by becoming a 401(k) plan's trustee. HBS professor Lauren Cohen and colleague Breno Schmidt provide evidence consistent with the trustee relationship affecting families' portfolio choice decisions. These portfolio decisions, however, have the potential to be in conflict with the fiduciary responsibility mutual funds have for their investors, and can impose potentially large costs. Key concepts include: Mutual fund families systematically distort their portfolios to attract 401(k) clients, presenting a conflict of interest. Mutual fund families that become trustees significantly overweight 401(k) sponsor firms' stock in their fund families. The trustee family performs a valuable service to the sponsor company by buying or holding its stocks around times of substantial selling of the sponsor firm by all other funds. Increased buying of sponsor firm shares by its trustee can have substantial price impact by propping up the sponsor firm's price. The overweighting can in some cases result in a large cost to the mutual fund investors. One possible remedy is to require the trustee to be independent of the mutual fund providers in the plan. This could greatly reduce the overweighting behavior currently seen by ostensibly ridding the relationship of its embedded, and unneeded, conflict of interest. Closed for comment; 0 Comments.
Exploring the Duality between Product and Organizational Architectures: A Test of the Mirroring Hypothesis
Products are often said to "mirror" the architectures of the organization from which they come. Is there really a link between a product's architecture and the characteristics of the organization behind it? The coauthors of this working paper chose to analyze software products because of a unique opportunity to examine two different organizational modes for development, comparing open-source with proprietary "closed-source" software. The results have important implications for development organizations given the recent trend toward "open" approaches to innovation and the increased use of partnering in research and development projects. Key concepts include: A product's architecture tends to mirror the structure of the organization within which it is developed. New organizational arrangements can have a distinct impact on the nature of the resulting design, and hence may affect product performance in unintended ways. There are substantial differences in relative levels of modularity between software systems of similar size and function. Closed for comment; 0 Comments.
