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.

A Paradoxical Free Trade Agreement

Author
Noam, Eli
The paradox of the free trade agreement (FTA) is that American media and information industries will help overcome the opposition to the FTA only if they expect to gain concretely rather than only symbolically. But if Korean media and cultural critics, understandably concerned and passionate about their business prospects and national culture, expect the same, then the FTA will encounter difficulties in Korea which is also engulfed in a major presidential election.

Agency Conflicts, Asset Substitution, and Securitization

Author
Mayer, Christopher and Yingjin Hila Gan

Under securitization, agents perform functions (for fees) that would alternatively be performed by a vertically integrated lender with ownership of a whole loan. We examine how outsourcing impacts performance using data on 357 commercial mortgage-backed securities deals with over 46,000 individual loans. To alleviate agency conflicts in managing troubled loans, underwriters often sell the first-loss position to the special servicer, the party who is charged with handling delinquencies and defaults.

A binomial lattice method for pricing corporate debt and modeling Chapter 11 proceedings

Author
Broadie, Mark and O. Kaya

The pricing of corporate debt is still a challenging and active research area in corporate finance. Starting with Merton (1974), many authors proposed a structural approach in which the value of the assets of the firm is modeled by a stochastic process, and all other variables are derived from this basic process. These structural models have become more complex over time in order to capture more realistic aspects of bankruptcy proceedings.

Adaptive Idea Screening Using Consumers

Author
Toubia, Olivier

Following a successful idea generation exercise, a company might easily be left with hundreds of ideas, generated by experts, employees, or consumers. The next step is to screen these ideas, and identify those with the highest potential. In this paper we propose a practical approach to involving consumers in idea screening. Although the number of ideas may potentially be very large, it would be unreasonable to ask each consumer to evaluate more than a few ideas. This raises the challenge of efficiently selecting the ideas to be evaluated by each consumer.

Asymmetric Discounting in Intertemporal Choice: A Query-Theory Account

Author
Weber, Elke, Eric Johnson, Kerry Milch, Hannah Chang, Jeff Brodscholl, and Daniel Goldstein
People are impatient and discount future rewards more when they are asked to delay consumption than when they are offered the chance to accelerate consumption. The three experiments reported here provide a process-level account for this asymmetry, with implications for designing decision environments that promote less impulsivity. In Experiment 1, a thought-listing procedure showed that people decompose discount valuation into two queries.

Managing Marketing in the 21st Century

Author
Capon, Noel and James Hulbert
Marketing activity is at the core of managing a business; it provides the focus for interfacing with customers and is the primary source of intelligence about customers, competitors, and the business environment in general. Marketing must be concerned with the long-run relationship of the firm with its customers as well as short-run sales activity. In this era of managerial concerns such as quality management, downsizing, reengineering, and outsourcing, marketing has become a major organizational thrust rather than just a task assigned to a single functional department.

The FASB's Conceptual Framework for Financial Reporting: A Critical Analysis

Author
Benston, George, Douglas Carmichael, Joel Demski, Bala Dharan, Karim Jamal, Robert Laux, Shivaram Rajgopal, and George Vrana

This paper addresses the issues that confront the FASB and IASB in developing a new conceptual framework document. First, we suggest characteristics that a conceptual framework ought to exhibit. Most of these suggestions are based on our critique of the existing framework and the FASB-IASB work in progress. Second, we present a model framework that exhibits these characteristics. We emphasize up front that this framework is quite explicit. It goes to the heart of what a framework document should do: it places specific restrictions on what constitutes admissible accounting standards.

The Investment Behavior of Buyout Funds: Theory and Evidence

Author
Ljungqvist, Alexander, Matthew Richardson, and Daniel Wolfenzon

This paper analyzes the determinants of buyout funds' investment decisions. In a model in which the supply of capital is "sticky" in the short run, we link the timing of funds' investment decisions, their risk-taking behavior, and the returns they subsequently earn on their buyouts to changes in the demand for private equity, conditions in the credit market, and funds' ability to influence their perceived talent in the market. Using a proprietary dataset of 207 buyout funds that invested in 2,274 buyout targets over the last two decades, we then investigate the implications of the model.

Achieving optimal agreements

Author
Leonardelli, G.J., Adam Galinsky, G. Okhuysen, and T. Mussweiler
Focusing on promoting success rather than preventing failure can be a powerful tool for achieving one's goals at the bargaining table. Across two studies, the authors find that "promotion-focused" negotiators pay greater attention to their goals than do "prevention-focused" negotiators. Attending to goals not only leads negotiators to strive for and achieve them, and thereby accrue more advantageous distributive outcomes, but it also prevents them from simply settling for minimally-acceptable outcomes and compromises.

Choice Goal Attainment and Decision and Consumption Satisfaction

Author
Lehmann, Donald, Andreas Herrmann, and Mark Heitmann

Several individual, social-setting, and choice-set factors have been shown to be related to satisfaction. This article argues that these factors operate through a set of choice goals. Using panel data on purchasers of consumer electronics, the authors examine how five goals (justifiability, confidence, anticipated regret, evaluation costs, and final negative affect) drive decision and consumption satisfaction, which in turn determine loyalty, product recommendations, and the amount and valence of word of mouth.

Correlation expansions for CDO pricing

Author
Glasserman, Paul and Sira Suchintabandid

This paper develops numerical approximations for pricing collateralized debt obligations (CDOs) and other portfolio credit derivatives in the multifactor Normal Copula model. A key aspect of pricing portfolio credit derivatives is capturing dependence between the defaults of the elements of the portfolio. But, compared with an independent-obligor model, pricing in a model with correlated defaults is more challenging. Our approach strikes a balance by reducing the problem of pricing in a model with correlated defaults to calculations involving only independent defaults.

Do Macro Variables, Asset Markets, or Surveys Forecast Inflation Better?

Author
Bekaert, Geert and Min Wei

Surveys do! We examine the forecasting power of four alternative methods of forecasting U.S. inflation out-of-sample: time-series ARIMA models; regressions using real activity measures motivated from the Phillips curve; term structure models that include linear, non-linear, and arbitrage-free specifications; and survey-based measures. We also investigate several methods of combining forecasts. Our results show that surveys outperform the other forecasting methods and that the term structure specifications perform relatively poorly.

Probabilistic Greedy Algorithms for Satisfiability Problems

Author
Kohli, Rajeev and Ramesh Krishnamurti
We examine probabilistic greedy heuristics for maximization and minimization versions of the satisfiability problem. Like deterministic greedy algorithms, these heuristics construct a truth assignment one variable at a time. Unlike them, they set a variable true or false using a probabilistic mechanism, the probabilities of a true assignment depending on the incremental number of clauses satisfied if a variable is set true. We discuss alternative probabilistic functions, and characterize the expected performance of the simplest of these rules relative to optimal solutions.

Recurrent Investment Opportunities: Real Options with Illiquid Projects

Author
Grenadier, Steven and Neng Wang

Although the vast majority of real options models assume that investment opportunities are permanently available, many real-world investment opportunities are sporadic. Options to invest can suddenly become blacked-out, only to be followed by a re-opening in the future. For example, the option to develop real estate may open or close depending upon zoning and growth control decisions, competitive entry, or input (labor or material) availability. Similar factors influence complex R&D options. We term such randomly recurring investment opportunities as options on illiquid projects.

The WTO Promotes Trade, Strongly but Unevenly

Author
Subramanian, Arvind and Shang-Jin Wei

This paper furnishes robust evidence that the WTO has had a strong positive impact on trade, amounting to about 120 percent of additional world trade (or US$ 8 trillion in 2000 alone). The impact has, however, been uneven. This, in many ways, is consistent with theoretical models of the GATT/WTO. The theory suggests that the impact of a country's membership in the GATT/WTO depends on what the country does with its membership, with whom it negotiates, and which products the negotiation covers.

Understanding Index Option Returns

Author

Previous research concludes that options are mispriced based on the high average returns, CAPM alphas, and Sharpe ratios of various put selling strategies. One criticism of these conclusions is that these benchmarks are ill-suited to handle the extreme statistical nature of option returns generated by nonlinear payoffs. We propose an alternative way to evaluate the statistical significance of option returns by comparing historical statistics to those generated by well-accepted option pricing models.

The time has come to engage in a new discussion on the role of the state in the next generation of electronic communications. For almost a generation now the dominant approach has been that of deregulation, privatisation, competition and free trade. It was believed that in time the role of the state as owner or regulator of communications infrastructure would wither away.This approach, whose impetus came especially from universities, took hold in American public policy, and spread around the globe. In time, it became the governing orthodoxy.

This paper develops a pure simulation-based approach for computing maximum likelihood estimates in latent state variable models using Markov Chain Monte Carlo methods (MCMC). Our MCMC algorithm simultaneously evaluates and optimizes the likelihood function without resorting to gradient methods. The approach relies on data augmentation, with insights similar to simulated annealing and evolutionary Monte Carlo algorithms. We prove a limit theorem in the degree of data augmentation and use this to provide standard errors and convergence diagnostics.

BACKGROUND: Delays for appointments are prevalent, resulting in patient dissatisfaction, higher costs, and possible adverse clinical consequences. A "just-in-time" approach to patient scheduling, called advanced access, has been effective in reducing delays in multiple clinical settings. Offering most patients appointments on the same day requires achieving an appropriate balance between supply of and demand for appointments, but no methods have been previously proposed to determine what this balance should be.

Our two-stage framework predicts that, during impression formation, individuals who hold ambivalent attitudes toward an issue are influenced by other sources regardless of their perceived reliability on the target issue. Less ambivalent individuals are presumed likely to check the reliability of the message's source before accepting it. Experiment 1 finds that highly ambivalent participants do not differentiate between a more versus less reliable source when forming impressions of a political candidate, whereas less ambivalent participants do.

Managerial Discretion and the Economic Determinants of the Disclosed Volatility Parameter for Valuing ESOs

Author

This study investigates the determinants of the expected stock-price volatility assumption that firms use in estimating ESO values and thus option expense. We find that, consistent with the guidance of FAS 123, firms use both historical and implied volatility in deriving the expected volatility parameter. We also find, however, that the importance of each of the two variables in explaining disclosed volatility relates inversely to their values, which results in a reduction in expected volatility and thus option value.

Three studies support the proposal that need for closure (NFC) involves a desire for consensual validation that leads to cultural conformity. Individual differences in NFC interact with cultural group variables to determine East Asian versus Western differences in conflict style and procedural preferences (Study 1), information gathering in disputes (Study 2), and fairness judgment in reward allocations (Study 3).

The Impact of Collateralization on Swap Rates

Author
Johannes, Michael and M. Suresh Sundaresan

Interest rate swap pricing theory traditionally views swaps as portfolios of forward contracts with net swap payments discounted using the LIBOR curve. Current market practices of marking-to-market and collateralization question this view. Collateralization and marking-to-market affects discounting of swap payments (through altered default characteristics) and introduces intermediate cash-flows. This paper provides a theory of swap valuation under collateralization and we find evidence supporting the presence of costly collateral.

A Convex Optimization Approach to Modeling Consumer Heterogeneity in Conjoint Estimation

Author
Toubia, Olivier

We propose and test a new approach for modeling consumer heterogeneity in conjoint estimation based on convex optimization and statistical machine learning. We develop methods both for metric and choice data. Like hierarchical Bayes (HB), our methods shrink individual-level partworth estimates towards a population mean. However, while HB samples from a posterior distribution that is influenced by exogenous parameters (the parameters of the second-stage priors), we minimize a convex loss function that depends only on endogenous parameters.

Economics and Psychology: A Promising New Cross-Disciplinary Field

A Survey of Economic Theories and Field Evidence on Pro-Social Behavior

Author
Meier, Stephan
Standard economic theory predicts that public goods are often under-provided because individuals will free ride on the contributions of others since they cannot be excluded from using the public good. In reality, people free ride less often than is predicted by standard economic theory. People behave in a number of situations not according to narrow self-interest, but rather pro-socially. As a result of these conclusions, economists have turned to psychologists, who have studied pro-social behavior for quite a long time.

Accounting for Employee Stock Options and Other Contingent Equity Claims: Taking a Shareholder's View

Author
Ohlson, James and Stephen Penman

In this paper, we propose a method of accounting for stock options that tracks the effect of the options on shareholder value. The accounting approach we outline can be applied not only to employee stock options but to all claims that are effectively convertible into common shares, including convertible preferred stock, warrants, and call and put options on the firm's own stock. Our proposal also aims to make accounting consistent with stock prices, since the market surely takes account of the (potential) valuation effects of these claims when setting stock prices.

Additive and multiplicative duals for American option pricing

Author
Chen, Nan and Paul Glasserman

We investigate and compare two dual formulations of the American option pricing problem based on two decompositions of supermartingales: the additive dual of Haugh and Kogan (Oper. Res. 52:258-270, 2004) and Rogers (Math. Finance 12:271-286, 2002) and the multiplicative dual of Jamshidian (Minimax optimality of Bermudan and American claims and their Monte-Carlo upper bound approximation. NIB Capital, The Hague, 2003).
