A Framework for Technology Forecasting and Visualization (Working paper) This paper presents a novel framework for supporting the development of well-informed research policies and plans. The proposed methodology is based on the use of bibliometrics; i.e., analysis is conducted using information regarding trends and patterns of publication. Information thus obtained is analyzed to predict probable future developments in the technological fields being studied. While using bibliometric techniques to study science and technology is not a new idea, the proposed approach extends previous studies in a number of important ways. More >> |

Profiting from voluntary information spillovers: How users benefit by freely revealing their innovations (Working paper) Empirical studies of innovation have found that end users frequently develop important product and process innovations. Defying conventional wisdom on the negative effects of uncompensated spillovers, innovative users also often openly reveal their innovations to competing users and to manufacturers. More >> |
|
Users as Service Innovators: The Case of Banking Services (Working paper) Many services can be self-provided. An individual user or a user firm can, for example, choose to do its own accounting - choose to self-provide that service - instead of hiring an accounting firm to provide it. More >> |

Why Markets Make Mistakes (Working paper) Many models of markets are based on assumptions of rationality, transparency, efficiency, and homogeneity in various combinations. They assume, at least implicitly, that decision makers understand the structure of the market and how it produces the dynamics which can be observed or might potentially occur. Are these models acceptable simplifications, or can they be seriously misleading? More >> |

Open Source Software and the "Private-Collective" Innovation Model: Issues for Organization Science (Working paper) Currently two models of innovation are prevalent in organization science. The "private investment" model assumes returns to the innovator results from private goods and efficient regimes of intellectual property protection. The "collective action" model assumes that under conditions of market failure, innovators collaborate in order to produce a public good. The phenomenon of open source software development shows that users program to solve their own as well as shared technical problems, and freely reveal their innovations without appropriating private returns from selling the software.

The Truth About Middle Managers (Book) "Middle management" is a term associated with relentless downsizing, corporate drudgery, and career dead-ends. Bashed by management gurus, dismissed by social scientists, and painted as victims by the media, middle managers seem permanently relegated to the sidelines of corporate power. More >> |
|
Bibliometric Analysis of Distributed Generation (Working paper) This paper describes the application of data mining techniques for eludicating patterns and trends in technological innovation. Specifically, we focus on the use of bibliometric methods, viz techniques which focus on trends in the publication of text documents rather than the content of these documents. More >> |

Sunk Costs and Risk-Based Barriers to Entry (Working paper) In merger analysis and other antitrust settings, risk is often cited as a potential barrier to entry. But there is little consensus as to the kinds of risk that matter -- systematic versus non-systematic and industry-wide versus firm-specific -- and the mechanisms through which they affect entry. More >> |
|
Behavior Modes, Pathways and Overall Trajectories: Eigenvector and Eigenvalue Analysis of Dynamic Systems (Published paper) One of the most fundamental principles in system dynamics is the premise that the structure of the system will generate its behavior. Such philosophical position has fostered the development of a number of formal methods aimed at understanding the causes of model behavior. More >> |
|
The Prevalence of User Innovation and Free Innovation Transfers: Implications for Statistical Indicators and Innovation Policy (Working paper) Statistical indicators have not kept pace with innovation research. Today, it is well understood that many industrial and consumer products are developed by users, and that many innovations developed at private cost are freely shared. New statistical indicators will empower policymakers to take advantage of the latest research findings in their innovation policymaking, and will enable them to benefit from improved measurement of resulting policy impacts.

To Wave Or Not To Wave? Order Release Policies for Warehouses with an Automated Sorter (Working paper) Wave-based release policies are prevalent in warehouses with an automated sorter, and take different forms depending on how much waves overlap and whether the sorter is split for operating purposes. Waveless release is emerging as an alternative policy adopted by an increasing number of firms. While that new policy presents several advantages relative to waves, it also involves the possibility of gridlock at the sorter. More >> |

A Fire Sale without Fire: An Explanation of Labor-Intensive FDI in China (Working paper) Using a large firm-level panel dataset from the Chinese National Bureau of Statistics, we examine the effect of financial distortions on FDI inflows in China's labor-intensive industries. Following Whited and Wu (2006), we estimate the investment Euler equation and construct a financing constraint index for each firm. We find that among domestic firms, the financing constraint index is highest for private firms and lowest for state-owned firms. More >> |
|
Liquidation Values and the Credibility of Financial Contract Renegotiation: Evidence from U.S. Airlines (Published Paper) How do liquidation values affect financial contract renegotiation? While the 'incomplete contracting' theory of financial contracting predicts that liquidation values determine the allocation of bargaining power between creditors and debtors, there is little empirical evidence on financial contract renegotiations and the role asset values play in such bargaining. More >> |
|
Investor Protection and the Coasian View (Published Paper) The corporate charters of a sample of Mexican firms show that private firms often significantly enhance the legal protection offered to investors, but public firms rarely do so. We construct a model that endogenizes the degree of investor protection that firms provide, using as a springboard the assumption that legal regimes differ in their ability to enforce precisely filtering contracts that provide protection only in those cases where expropriation can occur.

Asymmetric Information Distances for Automated Taxonomy Construction (Working paper) A novel method for automatically constructing taxonomies for specific research domains is presented. The proposed methodology uses term co-occurence frequencies as an indicator of the semantic closeness between terms. More >> |
|
Semantic Distances for Technology Landscape Visualization (Working paper) This paper presents a novel approach to the visualization and subsequent elucidation of research domains in science and technology.

Preventing Accidents and Building a Culture of Safety: Insights from a Simulation Model (Working paper) Research has approached the topic of safety in organizations from a number of different perspectives. On the one hand, psychological research on safety climate gives evidence for a range of organizational factors that predict safety across organizations. On the other hand, organizational learning theorists view safety as a dynamic problem in which organizations must learn from mistakes. Here, we synthesize these two streams of research. More >> |

Capitalism with Chinese Characteristics (Book) This book presents a story of two Chinas -- an entrepreneurial rural China and a state-controlled urban China. In the 1980s, rural China gained the upper hand, and the result was rapid as well as broad-based growth. In the 1990s, urban China triumphed. In the 1990s, the Chinese state reversed many of its productive rural experiments, with long-lasting damage to the economy and society. A weak financial sector, income disparity, rising illiteracy, productivity slowdowns, and reduced personal income growth are the product of the capitalism with Chinese characteristics of the 1990s and beyond.

Implementing Supply Routing Optimization in a Make-to-Order Manufacturing Network (Working paper) Dell's supply chain for desktops involves Asian vendors shipping components by sea to several U.S. plants. While suppliers are responsible for shipping enough inventory, Dell can re-route and expedite their shipments while in transit and also transfer on-hand inventory in order to balance supply across sites. This paper describes the development, implementation and impact of the process and optimization-based control system now used by Dell to address this supply routing challenge for its US-bound monitors. This new methodology is estimated to have reduced Dell's inventory re-positioning costs for monitors by about 60 percent. More >> |

Is Entrepreneurship Missing in Shanghai? (Working paper) Using a unique census dataset on all industrial firms (with more than 5 million yuan in sales), we document a phenomenon of missing entrepreneurship in Shanghai. Entrepreneurship is defined as private, new entrants in our paper. Specifically, in terms of business density, the size of employment and a host of other measures, the relative ranking of Shanghai was always near the bottom in the country. All these empirical findings took place against a backdrop of the presumably huge locational advantages of Shanghai -- the substantial human capital, rapid GDP growth, and a long and stellar -- but pre-communist -- history of entrepreneurship. We propose a hypothesis that Shanghai adopted a particularly rigorous version of industrial policy model of economic development and this industrial policy proclivity may have led to the atrophy of entrepreneurship in Shanghai.

Predictably Irrational: The Hidden Forces That Shape Our Decisions (Book) Irrational behavior is a part of human nature, but as MIT professor Ariely has discovered in 20 years of researching behavioral economics, people tend to behave irrationally in a predictable fashion. Drawing on psychology and economics, behavioral economics can show us why cautious people make poor decisions about sex when aroused, why patients get greater relief from a more expensive drug over its cheaper counterpart and why honest people may steal office supplies or communal food, but not money.

Do Short Sellers Front-Run Insider Sales? (Working paper) We find evidence of significant increases in short sales immediately prior to large insider sales, consistent with information leakage and front-running. We examine a number of alternative explanations that the increase in short sales is driven by public information about the firm or about the impending insider sale, but the evidence is inconsistent with these explanations. The result has implications for the enforcement of insider information regulations, and for timely disclosure of short sales information by stock exchanges. More >> |

What Can We Conclude From Common Tests of Accrual Mispricing? (Working paper) Mispricing and risk have both been suggested as explanations for the cross-sectional relation between stock returns and firm characteristics such as accruals. As emphasized by Ferson and Harvey (1998) and Berk, Green and Naik (1999), it is difficult to evaluate these competing explanations without explicitly modelling the relation between risk and firm characteristics, if risk is not independent of firm characteristics. Drawing on theory and empirical evidence, this paper models systematic risk as a function of accruals, and accruals as mean-reverting. More >> |

Friends and Enemies Within: The Roles of Subgroups, Imbalance, and Isolates in Geographically Dispersed Teams (Working paper) In this study, we explore the impact of GDT configuration (i.e., the relative number of team members at different sites, independent of the characteristics of those members or the spatial and temporal distances among them) on GDT dynamics. More >> |
|
Fuzzy Teams: Why do teams disagree on their membership, and what does it mean? (Working paper) Organizations increasingly rely on teams as fundamental building blocks -- a focus mirrored by a long legacy of research on teams. Due to the complexity of team dynamics and processes within teams and small groups, to date such research has yielded an ambiguous or equivocal set of results regarding the determinants of team performance.

Economic Benefits of Air Pollution Regulation in the USA: An Integrated Approach (Published paper) Market and non-market effects of air pollution on human health are estimated for the U.S. for the period from 1970 to 2000. The pollutants include tropospheric ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and particulate matter. We develop a methodology for integrating the health effects from exposure to air pollution into the MIT Emissions Prediction and Policy Analysis (EPPA) model, a computable general equilibrium model of the economy that has been widely used to study climate change policy.

What Happened to the Quants in August 2007 (Published paper) During the week of August 6, 2007, a number of quantitative long/short equity hedge funds experienced unprecedented losses. Based on TASS hedge-fund data and simulations of a specific long/short equity strategy, we hypothesize that the losses were initiated by the rapid "unwind" of one or more sizable quantitative equity market-neutral portfolios. Given the speed and price impact with which this occurred, it was likely the result of a forced liquidation by a multi-strategy fund or proprietary-trading desk, possibly due to a margin call or a risk reduction. These initial losses then put pressure on a broader set of long/short and long-only equity portfolios, causing further losses by triggering stop/loss and de-leveraging policies. More >> |

Securities Trading of Concepts (Published paper) Market prices are well known to efficiently collect and aggregate diverse information regarding the economic value of goods, services, and firms, particularly when trading financial securities. We propose a novel application of the price discovery mechanism in the context of marketing research: to use pseudo-securities markets to measure consumer preferences for new product concepts. This is the first research to test potential new product concepts using virtual markets and the first to validate such an approach using eight years of stated-choice and longitudinal revealed preference data. We directly address the challenge of validating simulated market results in which actual outcomes cannot be observed. More >> |

Potential Land Use Implications of a Global Biofuels Industry (Published paper) In this paper we investigate the potential production and implications of a global biofuels industry. We develop alternative approaches to consistently introduce land as an economic factor input and in physical terms into a computable general equilibrium framework. The approach allows us to parameterize biomass production consistent with agro-engineering information on yields and a "second generation" cellulosic biomass conversion technology. We explicitly model land conversion from natural areas to agricultural use in two different ways: in one approach we introduced a land supply elasticity based on observed land supply responses and in the other approach we considered only the direct cost of conversion. We estimate biofuels production at the end of the century could reach 221 to 267 EJ in a reference scenario and 319 to 368 EJ under a global effort to mitigate greenhouse gas emissions. More >> |

Climate Change Taxes and Energy Efficiency in Japan (Published paper) In 2003 Japan proposed a Climate Change Tax to reduce its CO2 emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless the subsidy encourages improvement in energy intensity well beyond Japan's recent historical experience. Similar demand-management programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading. We find that this limit substantially affects costs of compliance. More >> |

Global Economic Effects of Changes in Crops, Pasture, and Forests due to Changing Climate, Carbon Dioxide, and Ozone (Published paper) Multiple environmental changes will have consequences for global vegetation. To the extent that crop yields and pasture and forest productivity are affected there can be important economic consequences. We examine the combined effects of changes in climate, increases in carbon dioxide, and changes in tropospheric ozone on crop, pasture, and forest lands and the consequences for the global and regional economies. We examine scenarios where there is limited or little effort to control these substances, and policy scenarios that limit emissions of CO2 and ozone precursors. We find the effects of climate and CO2 to be generally positive, and the effects of ozone to be very detrimental. Unless ozone is strongly controlled damage could offset CO2 and climate benefits. We find that resource allocation among sectors in the economy, and trade among countries, can strongly affect the estimate of economic effect in a country. More >> |

Productivity Effects of Information Diffusion in Networks (Working paper) We examine the drivers of diffusion of information through organizations and the effects on performance. In particular, we ask: What predicts the likelihood of an individual becoming aware of a strategic piece of information, or becoming aware of it sooner? Do different types of information exhibit different diffusion patterns, and do different characteristics of social structure, relationships and individuals in turn affect access to different kinds of information?

Email, Social Networks and Performance: An Econometric Case Study (Working paper) This research investigates the efficient use of social networks by a specific group of white collar workers. Using a unique data set containing email patterns and accounting records for several dozen executive recruiters, we examine two existing theories relating network position and tie strength to performance. A structural holes argument suggests recruiters who cultivate more diverse contacts will be higher performers based on a greater ability to identify novel combinations of information. A transfer argument suggests recruiters who maintain strong ties with teammates will be higher performers based on a greater ability to exchange complex information. We find statistically significant relationships between email and performance measures that are consistent with these theories. But recruiters' general perceptions of communication with colleagues over email do not correlate with performance. Direct measures of communication show greater predictive power than self-reports of time and value. Further, communication networks are better predictors than contract networks. We conclude that the analysis of electronic archival data on communication networks offers significant opportunities for improving performance. More >> |

The MIT Collaboratorium: Enabling Effective Large-Scale Deliberation for Complex Problems (Working paper) While current online discussion tools such as email, chat, wikis, and web forums have been enormously successful at enabling unprecedented global knowledge sharing, they face significant limitations from the perspective of enabling effective large-scale deliberation around complex and controversial issues such as climate change. This paper describes the design and rationale of a system, called the Collaboratorium, which was developed to transcend these limitations by supporting large-scale on-line argumentation. More >> |

System Dynamics--a personal view of the first fifty years (Published paper) I present a personal recollection of the history of system dynamics and observations about its present state. The article treats the history in two parts: first, my personal background and how all the threads came together to initiate the field of system dynamics; and second, the historical development of the cornerstone projects that shaped the field. These early works include industrial dynamics, urban dynamics, world dynamics, and the national economic model. The paper continues with an assessment of the present condition of the field. A companion paper (System Dynamics--The Next Fifty Years, also in this issue of System Dynamics Review), highlights challenges for the future. More >> |

Decomposing the Congestion Effect and the Inference Effect of Competition: A Field Experiment (Working paper) Are firms more or less likely to enter a market if they observe that competitors have entered? This most basic question has received contradictory empirical answers. The normative recommendation to firms that make entry decisions is therefore ambiguous. We reconcile this controversy by introducing demand uncertainty as a moderator of how entrants respond to existing competition. We distinguish between two effects of competition on entry decisions: a negative "congestion effect," where competition dissipates profit when demand is fixed and is known, and a positive "inference effect," where firms infer high demand from a large number of competitors. To tease apart these two effects empirically, we use field experiment data from a website that brings together buyers and sellers of used goods. Before each potential seller made a posting request, the website randomized whether to disclose the number of buyers and/or sellers, and the exact number to disclose. We find evidence for a positive inference effect: When the number of buyers is not disclosed, the overall effect of the number of sellers on entry is neutral; when the number of buyer is disclosed, however, a larger number of sellers lowers the entry propensity due to the congestion effect. We discuss how our results should affect the information disclosure strategies of two-sided platforms. More >> |

The Shift from Centralized to Peer-to-Peer Communication in an Online Community: Participants as a Useful Aspect of Genre Analysis (Working paper) In this paper we analyzed an online community based on a mailing list that was created as an internal marketing tool for launching a new network service. We focused on the change in communication over time among dispersed Sales representatives and the employees in a centralized Service Department. We conducted a genre analysis based on content (what), purpose (why), timing (when), form (how) and participants (who communicates to whom) (Yates and Orlikowski, 2002). Analyzing the participants in a genre and how those participants changed over time highlighted a shift from centralized to dispersed, peer-to-peer communication in this community. We highlight implications both for genre analysis and for organizational practice. More >> |

The Information in Option Volume for Future Stock Prices (Published paper) We present strong evidence that option trading volume contains information about future stock prices. Taking advantage of a unique data set, we construct put-call ratios from option volume initiated by buyers to open new positions. Stocks with low put-call ratios outperform stocks with high put-call ratios by more than 40 basis points on the next day and more than 1% over the next week. More >> |

Pricing American Options: A Duality Approach (Published paper) We develop a new method for pricing American options. The main practical contribution of this paper is a general algorithm for constructing upper and lower bounds on the true price of the option using any approximation to the option price. We show that our bounds are tight, so that if the initial approximation is close to the true price of the option, the bounds are also guaranteed to be close. More >> |

Asset Prices and Real Investment (Published paper) Firm investment activity and firm characteristics, particularly the market-to-book ratio or q, are functions of the state of the economy and therefore contain information about the dynamic behavior of stock returns. This paper develops a model of a production economy in which real investment is irreversible and subject to convex adjustment costs. More >> |

The Survival and Price Impact of Irrational Traders (Published paper) Milton Friedman argued that irrational traders will consistently lose money, will not survive, and, therefore, cannot influence long-run asset prices. Since his work, survival and price impact have been assumed to be the same. In this paper, we demonstrate that survival and price impact are two independent concepts. More >> |

Dynamic Analysis in the Social Sciences (Book) The study of social dynamics using quantitative methodology is complex and calls for cutting-edge technical and methodological approaches in social science research. This book presents the existing statistical models and methods available for understanding social change over time. It provides step-by-step instructions for designing and conducting longitudinal research, with special focus on the longitudinal analysis of both quantitative outcomes (for the modeling of change in continuous variables) and qualitative outcomes (for the modeling of events occurring over time).

Contingent Claims Analysis and Life-Cycle Finance (Working paper) This paper explores the application of contingent claims analysis (CCA) to two "hot" issues in life-cycle finance: (1) investing for retirement and (2) deciding when, if ever, to switch careers. Participants in individual retirement accounts do not have the time or the knowledge to make their own investment decisions. Today they are defaulted into life-cycle mutual funds that pass all risk directly through to the participant. We use CCA to demonstrate how financial firms can design and produce guaranteed contingent benefit contracts that improve participant welfare at no additional cost to the system. In exploring the career-choice issue in the second part of the paper, we use CCA in a somewhat different way. The decision to switch careers is analogous to deciding when to exercise an American-style option to swap one asset for another. By applying the methods used to analyze the option-exercise decision to the career-switching problem, we gain some new insights beyond those derived from the traditional dynamic programming approaches.

Can We Exploit Collective Intelligence for Collaborative Deliberation? The Case of the Climate Change Collaboratorium (Working paper) Current open-source/peer-production technologies, such as forums, wikis and blogs, have enabled an unprecedented explosion of global knowledge sharing, but appear to be less successful at enabling collaborative deliberation (i.e. the systematic enumeration, analysis, and selection of solution alternatives) around the complex and controversial challenges, such as climate change, now facing humankind. In this paper, we present a new kind of collaboration platform, based on argumentation theory, which is aimed at addressing this weakness. We present the rationale for its design as well as preliminary results obtained from a first field test with a moderate-sized (200 member) user community. More >> |

Coordination of Supply Chain Networks and the Emergence of Mini-Maestros (Working paper) Companies recognize international sourcing as a business practice useful to reduce product prices, deal with supply shortages and identify new competitive suppliers. Effective international sourcing implies the integration and coordination of materials, processes, information flows and multiple producers at each buying location. Many companies do not have the capabilities or the willingness to develop and manage such sourcing networks; therefore, other entities have assumed these responsibilities. These coordinators are in charge of the integration of many suppliers to develop full-package production, serve as liaisons between suppliers' capabilities and market demands, and provide the technical and financial support to sustain the sourcing network. The review of the industrial clustering and global supply chain literature allowed the identification of such coordinators in Mexico. The emergence and profile of these coordinators is associated with corporate strategies of multinational firms, the efforts of industrial groups, and the governmental policies for the development of dynamic industrial regions. This paper analyzes the characteristics of four coordination models identified in the Mexican context, focusing on their contribution to the participation and upgrading of national suppliers. The profile of the coordinator firm, the type of relations that this firm sustains with producers and the support offered to suppliers is also discussed. A particular emphasis is given to the fourth model where a third party, a knowledge and service company, assumes the coordinator role. The interest on this model is due to its novelty, the flexibility of the sourcing network, and the potential impact on regional development that could result from the intervention of a neutral third party as coordinator of the activities of multiple local and specialized suppliers.

Enabling Global Price Comparison through Semantic Integration of Web Data (Working paper) "Sell Globally" and "Shop Globally" have been seen as a potential benefit of web-enabled electronic business. One important step toward realizing this benefit is to know how things are selling in various parts of the world. A global price comparison service would address this need. But there have not been many such services. In this paper, we use a case study of global price dispersion to illustrate the need and the value of a global price comparison service. Then we identify and discuss several technology challenges, including semantic heterogeneity, in providing a global price comparison service. We propose a mediation architecture to address the semantic heterogeneity problem, and demonstrate the feasibility of the proposed architecture by implementing a prototype that enables global price comparison using data from web sources in several countries.

Semantic Integration Approach to Efficient Business Data Supply Chain: Integration Approach to Interoperable XBRL (Working paper) As an open standard for electronic communication of business and financial data, XBRL has the potential of improving the efficiency of the business data supply chain. A number of jurisdictions have developed different XBRL taxonomies as their data standards. Semantic heterogeneity exists in these taxonomies, the corresponding instances, and the internal systems that store the original data. Consequently, there are still substantial difficulties in creating and using XBRL instances that involve multiple taxonomies. To fully realize the potential benefits of XBRL, we have to develop technologies to reconcile semantic heterogeneity and enable interoperability of various parts of the supply chain. In this paper, we analyze the XBRL standard and use examples of different taxonomies to illustrate the interoperability challenge. We also propose a technical solution that incorporates schema matching and context mediation techniques to improve the efficiency of the production and consumption of XBRL data. More >> |

Evaluating and Aggregating Data Believability across Quality Sub-Dimensions and Data Lineage (Working paper) Data quality is crucial for operational efficiency and sound decision making. This paper focuses on believability, a major aspect of data quality. The issue of believability is particularly relevant in the context of Web 2.0, where mashups facilitate the combination of data from different sources. Our approach for assessing data believability is based on provenance and lineage, i.e. the origin and subsequent processing history of data. We present the main concepts of our model for representing and storing data provenance, and an ontology of the sub-dimensions of data believability. We then use aggregation operators to compute believability across the sub-dimensions of data believability and the provenance of data. We illustrate our approach with a scenario based on Internet data. Our contribution lies in three main design artifacts (1) the provenance model (2) the ontology of believability subdimensions and (3) the method for computing and aggregating data believability. To our knowledge, this is the first work to operationalize provenance-based assessment of data believability. More >> |

Understanding Complexity: Dynamic Analysis of Combat Vehicle Accidents (Working paper) Dozens of U.S. soldiers are killed each year as a result of both combat and motor vehicle accidents. The objective of this study is to look beyond the events and symptoms of accidents which normally indicate human error, and instead study the complex and poorly understood upper-level organizational processes and problems that may constitute the actual root causes of accidents - this is particularly challenging because the causes often involve nonlinear dynamic phenomena and have behaviors that are counter-intuitive to normal human thinking, these are often called "wicked" problems. After reviewing the available literature, a System Dynamics model was created to provide an analytical model of this multifaceted system that allows for extensive simulation. The results of these simulations suggest that high-level decisions that balance mission rate and operations tempo with troop availability, careful management of the work-rest cycle for deployed troops, and improvement of the processes for evaluating the lessons learned from accidents, will lead to a reduction in Army combat and motor vehicle accidents.

Using Semantic Web Tools for Context Interchange (Working paper) The COntext INterchange Strategy (COIN) is an approach to solving the problem of interoperability of semantically heterogeneous data sources through context mediation. The existing implementation of COIN uses its own notation and syntax for representing ontologies. More recently, the OWL Web Ontology Language is becoming established as the W3C recommended ontology language. A bridge is needed between these two areas and an explanation on how each of the two approaches can learn from each other. We propose the use of the COIN strategy to solve context disparity and ontology interoperability problems in the emerging Semantic Web both at the ontology level and at the data level. In this work we showcase how the problems that arise from context-dependant representation of facts can be mitigated by Semantic Web techniques, as tools of the conceptual framework developed over 15 years of COIN research.

Interpersonal Authority in a Theory of the Firm (Working paper) This paper develops a theory of the firm in which a firm's centralized asset ownership and low-powered incentives give a manager 'interpersonal authority' over employees (in a world with differing priors). The paper derives such interpersonal authority as an equilibrium phenomenon. One key result is that a manager's control overcritical assets-through its effect on the level of outside options allows the manager to order employees what to do. The paper thus provides micro- foundations for the idea that bringing a project inside affirm gives the manager authority over that project, while-in the process-explaining concentrated asset ownership, low-powered incentives, and centralized authority as typical characteristics of firms. It also leads to a new perspective on the firm as a legal entity and, building on the insights of a parallel paper, to a new theory for firm Boundaries based on the idea of break-up. A key feature of the latter theory is that firm boundaries matter even though both ex-ante investments and ex-post actions are perfectly contractible. More >> |

Building Business Agility at Southwest Airlines (Working paper) Southwest Airlines has grown from upstart to the largest U.S. airline in terms of number of passengers flown while recording 34 consecutive years of profitability. Through most of those 34 years, Southwest management emphasized high touch rather than automation as critical to business success. Over time, however, Southwest employees introduced technology-based innovations to support key processes, including the industry's first paperless ticketing system and early entry into web-based applications. By 2002 then-CFO (and subsequently CEO) Gary Kelly recognized that IT would be important to meeting the company's strategic objectives. He initiated a business transformation that relied on building a strong IT foundation. This case describes the IT and business changes Southwest introduced to help the company succeed in its increasingly competitive environment. More >> |

Order Release Control for an Online Retailing Warehouse (Working paper) Working in collaboration with a large online retailer, our goal is to develop an operational solution to the problem of order release control for its highest volume and most automated warehouse pick-to-ship process. This problem consists of dynamically varying the rate at which new picking orders are released into this process in order to achieve a high throughput while mitigating the risk of congestion-induced collapse (gridlock). We describe a queueing model of this complex process with validated predictive accuracy against actual historical data, and develop a numerical approximate solution method for an associated constrained dynamic program, which we implemented to compute our proposed policy. Simulation experiments suggest that an implementation of our computed policy along with an increase in staffed packers by 25 percent could increase process throughput by 10 percent. They also shed light on why our proposed policy outperforms other simple release policies such as constant release rate and CONWIPin this setting, in terms of both steady-state throughput and robustness to transient disruptions.

Invisible Engines: How Software Platforms Drive Innovation and Transform Industries (Book) As they wait in long lines to buy the latest game console, few shoppers realize that the most important element of that Xbox (as well as of their cell phones, PDAs, web-based software such as eBay, and far more) is something they can't even see. Invisible Engines tells the important story of how invisible but powerful software platforms are driving not only today's technology, but tomorrow's innovations and economy. The book recounts the growth, development and marketing of software platforms, which have turned devices such as Sony's PlayStation and Apple's iPod into household names and tools for everyday life. Because software platforms can be used by independent companies or developers to offer a wide range of products and services, the authors note, they function as "invisible engines that have created, touched, or transformed nearly every major industry for the past quarter century."

Catalyst Code: The Strategies Behind the World's Most Dynamic Companies (Book) Catalysts are the new business powerbrokers. Fueled by the increasing interdependence of global markets, technology, and consumers, catalysts are reshaping entire industries as they mobilize two or more distinct customer groups around a common platform to create value and drive profits. Some of the world's most important businesses -- from Lloyd's of London and Hearst Newspapers to Microsoft and Google -- have made profits by simultaneously bringing together distinct customer groups who need each other onto the same platform. Their successes demonstrate that, to succeed, catalysts must defy traditional business and economic wisdom when designing business models, pricing schemes, and organizational incentives. Catalyst Code shows executives and entrepreneurs how to innovate and profit by detailing new economic theory and business history, as well as through extensive interviews with established and emerging catalysts.

X-Teams: How to Build Teams That Lead, Innovate and Succeed (Book) The X-Team is much more than just the latest B-school theory -- it's a well-established, but often hidden, reality that's now being highlighted by this new book. Challenging the traditional notions of what makes a successful team, the authors' years of research support a new way of doing things. This new kind of team, dubbed X-Teams, has team spirit, but the team also projects upwards and outwards. The group establishes cooperative relationships, seeks out key information from other teams and outside sources, evangelizes the team's mission to key stakeholders, and actively pursues support from management. The poorest-performing teams, on the other hand, focused inward. The book explains that X-teams not only are able to adapt in ways that traditional teams aren't, but that they actually improve an organization's ability to produce creative ideas and execute them -- increasing the entrepreneurial and innovative capacity within the firm.

Breaking the Mold (Book) In this second edition of Breaking the Mold, MIT Sloan Professor Lotte Bailyn maintains the long-standing separation between work and family life is an outdated concept. She contends that unless American business radically rethinks some of its basic assumptions about work, time, and career paths, both employee and employer will experience setbacks in today's intensely competitive business environment. Bailyn shows how the structure and culture of corporate life could be changed to integrate all of an employee's obligations and interests. And she illustrates the benefits that such change can have for the organization itself. More >> |

The Outside-in Corporation (Book) This book presents a new approach that enables business people to design and operate their businesses (both strategies and actions) based firmly on a customer perspective -- in other words, from the outside in. The approach works despite the real-world challenge that there is never as much available information about customers as business people want and need. It leads to marketplace strategies with a clear, explicit customer reason for every marketplace action -- strategies with improved probabilities of success, that can be communicated throughout an organization and then understood and implemented by employees at all levels, and that can be adapted effectively as conditions change.
