Columbia Business School Research

At the Forefront of Their Fields

At Columbia Business School, our faculty members are at the forefront of research in their respective fields, offering innovative ideas that directly impact the practice of business today. A quick glance at our publication on faculty research, CBS Insights, will give you a sense of the breadth and immediacy of the insight our professors provide.

As a student at the School, this will greatly enrich your education. In Columbia classrooms, you are at the cutting-edge of industry, studying the practices that others will later adopt and teach. As any business leader will tell you, in a competitive environment, being first puts you at a distinct advantage over your peers. Learn economic development from Ray Fisman, the Lambert Family Professor of Social Enterprise and a rising star in the field, or real estate from Chris Mayer, the Paul Milstein Professor of Real Estate, a renowned expert and frequent commentator on complex housing issues. This way, when you complete your degree, you'll be set up to succeed.

The Columbia Advantage

Columbia Business School in conjunction with the Office of the Dean provides its faculty, PhD students, and other research staff with resources and cutting edge tools and technology to help push the boundaries of business research.

Specifically, our goal is to seamlessly help faculty set up and execute their research programs. This includes, but is not limited to:

  • Highly skilled staff of full-time predoctoral fellows, summer research interns, and part-time research assistants
  • Access to centralized funding from the Dean's office and external grants to support research activities
  • Providing a state-of-the-art high-performance grid computing environment
  • Acquisition of proprietary data sets and access to various databases
  • Leading library which provides faculty with latest tools and techniques to enable digital scholarship

All these activities help to facilitate and streamline faculty research, and that of the doctoral students working with them.

Kellogg School of Management, Dispute Resolution Research Center

The Kidney Case is multi-person exercise that involves the allocation of a single kidney. Students read profiles of eight candidates for the kidney and make a first allocation decision. Each candidate was designed to be high on some allocation principles but low or unknown on others (e.g., best, match, time in cue, age, personal responsibility for disease, future benefits to society, etc.). Then, students are put into groups and assigned to advocate for one of the candidates. Each group will prepare and give a 3-minute presentation on why their candidate should receive the kidney.

Emissions abatement alone cannot address the consequences of global warming for weather disasters. We model how society adapts to manage disaster risks to capital stock. Optimal adaptation — a mix of firm-level efforts and public spending — varies as society learns about the adverse consequences of global warming for disaster arrivals. Taxes on capital are needed alongside those on carbon to achieve the first best.

American Economic Review: Papers and Proceedings

What are the sources of the returns to education? We study the allocation of higher education graduates from public institutions in Ohio across firms. We present three results. First, we confirm findings in the earlier literature of large pay differences across degrees. Second, we show that up to one quarter of pay premiums for higher degrees are explained by between-firm pay differences. Third, higher education degrees are associated with greater representation at the best-paying firms.

Negotiation

This article focuses on the role of threats in negotiations. Broadly speaking, a threat is a proposition that issues demands and warns of the costs of noncompliance. Even if neither party resorts to them, potential threats shadow most negotiations. Researchers have found that people actually evaluate their counterparts more favorably when they combine promises with threats rather than extend promises alone. Whereas promises encourage exploitation, the threat of punishment motivates cooperation.

Fundamental Instability: Why Telecom Is Becoming a Cyclical and Oligopolistic Industry

Author
Noam, Eli

This essay analyzes the long-term lessons of the recent upturn and downturn in the telecommunications industry. It concludes that volatility and cyclicality will be an inherent part of the telecom sector in the future. To deal with such instabilities, companies and investors seek consolidation and cooperation. Government, too, is likely to stress stability more than before. Hence, an oligopoly is likely to emerge as the equilibrium market structure, and with it some regulation.

Financial Crises

Fundamentals, Panics, and Bank Distress During the Depression

Author
Calomiris, Charles and Joseph Mason

We assemble bank-level and other data for Fed member banks to model determinants of bank failure. Fundamentals explain bank failure risk well. The first two Friedman-Schwartz crises are not associated with positive unexplained residual failure risk, or increased importance of bank illiquidity for forecasting failure. The third Friedman-Schwartz crisis is more ambiguous, but increased residual failure risk is small in the aggregate. The final crisis (early 1933) saw a large unexplained increase in bank failure risk.

Leadership at the Crossroads

Harnessing Power to Capture Leadership

Author
Galinsky, Adam, J. Jordan, and N. Sivanathan

This chapter examines the relationship between the related yet distinct constructs of power and leadership. Although power (asymmetric control over valued resources) is often a foundation of leadership (influencing and motivating a group of individuals towards a common goal), we consider power to be neither a necessary nor a sufficient condition for the emergence of leadership. We distinguish power from leadership along a number of dimensions and highlight that the relationship of power to leadership lies in power's psychological effects.

Has Economic Analysis Improved Regulatory Decisions?

Author
Hahn, Robert and Paul Tetlock
In response to the increasing impact of regulation, several governments have introduced economic analysis as a way of trying to improve regulatory policy. This paper provides a comprehensive assessment of government-supported economic analysis of regulation. We find that there is growing interest in the use of economic tools, such as benefit-cost analysis; however, the quality of analysis in the U.S. and European Union frequently fails to meet widely accepted guidelines. Furthermore, the relationship between analysis and policy decisions is tenuous.

Illegitimacy moderates the effects of power on approach

Author
Lammers, Joris, Adam Galinsky, E. Gordijn, and S. Otten

A wealth of research has found that power leads to behavioral approach and action. Four experiments demonstrate that this link between power and approach is broken when the power relationship is illegitimate. When power was primed to be legitimate or when power positions were assigned legitimately, the powerful demonstrated more approach than the powerless. However, when power was experienced as illegitimate, the powerless displayed as much approach as, or even more approach than, the powerful.

In search of the right touch: Interpersonal assertiveness in organizational life

Ames, Daniel

Recent evidence suggests that many organizational members and leaders are seen as under- or over-assertive by colleagues, suggesting that having the "right touch" with interpersonal assertiveness is a meaningful and widespread challenge. In this article, I review emerging work on the curvilinear relation between assertiveness and effectiveness, including evidence from both qualitative descriptions of coworkers and ratings of colleagues and leaders.

Inferring latent class lexicographic rules from choice data

Author
Jedidi, Kamel and Rajeev Kohli
A lexicographic rule orders multi-attribute alternatives in the same way as a dictionary orders words. Although no utility function can represent lexicographic preference over continuous, real-valued attributes, a constrained linear model suffices for representing such preferences over discrete attributes. We present an algorithm for inferring lexicographic structures from choice data. The primary difficulty in using such data is that it is seldom possible to obtain sufficient information to estimate individual-level preference functions.

This paper considers a profit maximizing make-to-order manufacturer that offers multiple products to a market of price and delay sensitive users, using a model that captures three aspects of particular interest: first, the joint use of dynamic pricing and leadtime quotation controls to manage demand; second, the presence of a dual sourcing mode that can expedite orders at a cost; and third, the interaction of the aforementioned demand controls with the operational decisions of sequencing and expediting that the firm must employ to optimize revenues and satisfy the quoted leadtimes.

We present six experiments that tested whether lacking control increases illusory pattern perception, which we define as the identification of a coherent and meaningful interrelationship among a set of random or unrelated stimuli. Participants who lacked control were more likely to perceive a variety of illusory patterns, including seeing images in noise, forming illusory correlations in stock market information, perceiving conspiracies, and developing superstitions.

Four experiments explored whether lacking power impairs executive functioning, testing the hypothesis that the cognitive presses of powerlessness increase vulnerability to performance decrements during complex executive tasks. In the first three experiments, low power impaired performance on executive-function tasks: The powerless were less effective than the powerful at updating (Experiment 1), inhibiting (Experiment 2), and planning (Experiment 3).

In this paper, we discuss earnings quality and the related concept of earnings management, focusing on the primary financial accounts. For each key line-item from the financial statements, we summarize accounting and economic considerations applicable to that item, discuss implications for earnings quality, evaluate the susceptibility of the item to manipulation, and identify potential red flags. The red flags and specific issues discussed for the individual line-items provide a framework for fundamental and contextual analysis by academic researchers and practitioners.

Man, My Brain Is Tired: Linking Depletion and Cognitive Effort in Choice

Author
Johnson, Eric
Understanding how limited resources influence decision making is important to theory and even more to important practice. I focus on two questions inspired by Baumeister et al.: (1) What exactly is depleted? and (2) Is it useful to employ Systems 1 and 2 in modeling depletion? I discuss possible candidates for depletion at both the neural and the cognitive process levels and argue that a dual process model of depletion makes a very clear set of testable predictions. Finally, I believe that understanding the causes of depletion is essential in designing helpful choice environments.

This article explores the use of marketing metrics by a sample of Vietnamese firms, providing an example of the use of marketing metrics in a "transition" economy as it grows and becomes more market and marketing driven. The analysis reports usage frequency and then develops a set of "correlation chains" linking firm characteristics, metric use, and various indicators of performance. Vietnamese managers generally report that several types of metrics are used. Ownership structure and industry also impact which metrics are utilized.

Meeting or Beating Analyst Expectations in the Post-Scandals World: Changes in Stock Market Rewards and Managerial Actions

Author
Koh, Kevin, Dawn Matsumoto, and Shivaram Rajgopal

The pressure to meet/beat analysts' expectations is often blamed for the recent onslaught of accounting scandals. We investigate changes in the meeting/beating phenomenon post-scandals and find that the stock market premium to meeting or just beating analyst estimates has disappeared while the premium to beating by a larger margin has diminished. In the post-scandals period, managers tend to meet or just beat analysts' forecasts less often. Further, managers rely less on income-increasing discretionary accruals and more on earnings guidance.

Individuals define themselves, at times, as who they are (e.g., a psychologist) and, at other times, as who they are not (e.g., not an economist). Drawing on social identity, optimal distinctiveness, and balance theories, four studies examined the nature of negational identity relative to affirmational identity. One study explored the conditions that increase negational identification and found that activating the need for distinctiveness increased the accessibility of negational identities.

Performance Measurement Manipulation: Cherry-Picking What to Correct

Author
Arya, A. and Jonathan Glover

A common feature of managerial and financial reporting is an iterative process wherein various parties selectively correct particular measurements by challenging them and subjecting them to increased scrutiny. We model this feature by adding an agent appeal stage to the standard moral hazard model and show that it can be optimal to allow the agent to decide which performance measures to appeal, despite the agent's incentive to cherry-pick. In the presence of measurement errors, the agent is incentivized by increased opportunities for cherry-picking that arise if he chooses the "right" vs.

Power and the objectification of social targets

Author

Objectification has been defined historically as a process of subjugation whereby people, like objects, are treated as means to an end. The authors hypothesized that objectification is a response to social power that involves approaching useful social targets regardless of the value of their other human qualities. Six studies found that under conditions of power, approach toward a social target was driven more by the target's usefulness, defined in terms of the perceiver's goals, than in low-power and baseline conditions.

Volatility is the key variable in option pricing models and for risk management in general. Not surprisingly, this has led to the recognition that volatility uncertainty is an important risk factor. This realization, in turn, has given rise to derivative instruments tied to volatility, such as variance swaps, volatility swaps, and options on both variance and volatility, which are specifically designed to help manage this risk. To price these contracts, a model is needed for the volatility process.

The authors identify a number of properties that the priority heuristic should have as a process model and illustrate how they may be tested.

Punishing Hubris: The Perils of Status Self-Enhancement in Teams and Organizations

Author
Anderson, Cameron, Daniel Ames, and Samuel Gosling

Individuals engage in status self-enhancement when they form an overly positive perception of their status in a group. We argue that status self-enhancement incurs social costs and, therefore, most individuals perceive their status accurately. In contrast, theories of positive illusions suggest status self-enhancement is beneficial for the individual and that most individuals overestimate their status. We found supportive evidence for our hypotheses in a social relations analysis of laboratory groups, an experiment that manipulated status self-enhancement, and a study of real-world groups.

Females exhibit stronger racial preferences than males. The richness of our data further allows us to identify many determinants of same-race preferences. Subjects' backgrounds, including the racial composition of the ZIP code where a subject grew up and the prevailing racial attitudes in a subject's state or country of origin, strongly influence same-race preferences.

Reducing delays for medical appointments: A queueing approach

Many primary care offices and other medical practices regularly experience long backlogs for appointments. These backlogs are exacerbated by a significant level of last-minute cancellations or "no-shows," which have the effect of wasting capacity. In this paper, we conceptualize such an appointment system as a single-server queueing system in which customers who are about to enter service have a state-dependent probability of not being served and may rejoin the queue.

Selecting a portfolio of suppliers under demand and supply risks

Author

We analyze a planning model for a firm or public organization that needs to cover uncertain demand for a given item by procuring supplies from multiple sources. Each source faces a random yield factor with a general probability distribution. The model considers a single demand season. All supplies need to be ordered before the start of the season. The planning problem amounts to selecting which of the given set of suppliers to retain, and how much to order from each, so as to minimize total procurement costs while ensuring that the uncertain demand is met with a given probability.

Social hierarchy: The self-reinforcing nature of power and status

Hierarchy is such a defining and pervasive feature of organizations that its forms and basic functions are often taken for granted in organizational research. In this review, we revisit some basic psychological and sociological elements of hierarchy and argue that status and power are two important yet distinct bases of hierarchical differentiation. We first define power and status and distinguish our definitions from previous conceptualizations. We then integrate a number of different literatures to explain why status and power hierarchies tend to be self-reinforcing.

We develop a structural demand model that captures the effect of out-of-stocks on customer choice. Our estimation method uses store-level data on sales and partial information on product availability. Our model allows for flexible substitution patterns which are based on utility maximization principles and can accommodate categorical and continuous product characteristics. The methodology can be applied to data from multiple markets and in categories with a relatively large number of alternatives, slow moving products and frequent out-of-stocks.
