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.
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:
All these activities help to facilitate and streamline faculty research, and that of the doctoral students working with them.
The article offers the authors' views on expatriate management programs and the benefits from executives interacting with the people and institutions of the host country. The idea that international experience or interaction between foreign managers and local people will help managers become more creative, entrepreneurial, and successful is discussed. The concept of integrative complexity in bi-cultural managers which enhances job performance is mentioned.
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.
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.
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.
It has been recently proposed that people can flexibly rely on sources of control that are both internal and external to the self to satisfy the need to believe that their world is under control (i.e., that events do not unfold randomly or haphazardly). Consistent with this, past research demonstrates that, when personal control is threatened, people defend external systems of control, such as God and government.
Four experiments explored whether 2 uniquely human characteristics — counterfactual thinking (imagining alternatives to the past) and the fundamental drive to create meaning in life — are causally related. Rather than implying a random quality to life, the authors hypothesized and found that counterfactual thinking heightens the meaningfulness of key life experiences. Reflecting on alternative pathways to pivotal turning points even produced greater meaning than directly reflecting on the meaning of the event itself.
The conventional wisdom is that politicians' rent-seeking motives increase public debt and deficits. This is because myopic politicians face political risk and prefer to extract political rents as early as possible. In this paper we study the determination of government debt and deficits in a dynamic political economy model. We show that this conventional wisdom relies on economic volatility being low relative to political uncertainty.
Lawrence Glaubinger, a Columbia Business School alumnus, became increasingly involved in running his 100-acre Christmas tree farm after he retired in 1992. Between 1993 and 2008, Glaubinger sold Ponderosa pines through an arrangement with Green Acres, a large retailer that bought Glaubinger's trees to sell at its nurseries. While Glaubinger Tree Farm sold the trees to Green Acre at a wholesale price based on its marginal cost, the retailer independently set retail pricing. Glaubinger suspected his tree farm could have shown higher profits if it had sold directly to consumers.
Identifying the right business model for addressing global customers and formalizing that model into a global customer management program is a key task for any firm with global aspirations. The key success factor is embedding the program firmly within the firm's corporate strategy. Simply leveraging domestic or regional account management into such a program will not deliver the desired results. Based on extensive research with a global company database, this article presents a framework for successfully introducing a global customer management program.
Marketing research and advertising strategic planning offer viable and financially attractive career options for anthropologists because many businesses seek deep understandings of consumer lifestyles and brand use. As professionally trained anthropologists operating in the corporate world, we see a bright future for anthropologists, but we believe that there are merits in broadening the typical anthropological approach to incorporate additional theory and methods from other social and behavioral sciences, particularly psychology.
We discuss the evolution in macroeconomic thought on the monetary policy transmission mechanism and present related empirical evidence. The core channels of policy transmission — the neoclassical links between short-term policy interest rates, other asset prices such as long-term interest rates, equity prices, and the exchange rate, and the consequent effects on household and business demand — have remained steady from early policy-oriented models (like the Penn-MIT-SSRC MPS model) to modern dynamic, stochastic general equilibrium (DSGE) models.
When bad things happen, companies need the right strategy for talking their way out of a mess and avoiding a calamitous pummeling of their corporate image. Choosing the best response can spell the difference between a brand's survival — even enhancement — and its irreversible tarnishing.
We develop an importance sampling (IS) algorithm to estimate the lower tail of the distribution of returns for a discretely rebalanced portfolio-one in which portfolio weights are reset at regular intervals. We use a more tractable continuously rebalanced portfolio to design the IS estimator. We analyze a limiting regime based on estimating probabilities farther in the tail while letting the rebalancing frequency increase.
New goods play a central role in many trade and growth models. We use detailed trade and firm-level data from India to investigate the relationship between declines in trade costs, imports of intermediate inputs and domestic firm product scope. We estimate substantial gains from trade through access to new imported inputs. Moreover, we find that lower input tariffs account on average for 31 percent of the new products introduced by domestic firms.
What makes people’s interest in doing an activity increase or decrease? Regulatory fit theory (E. T. Higgins, 2000) provides a new perspective on this classic issue by emphasizing the relation between people’s activity orientation, such as thinking of an activity as fun, and the manner of activity engagement that the surrounding situation supports.
We consider a general infinite horizon inventory control model which combines demand and supply risks and the firm's ability to mitigate the supply risks by diversifying its procurement orders among a set of N potential suppliers. Supply risks arise because only a random percentage of any given replenishment order is delivered as useable units. The suppliers are characterized by the price they charge and the distribution of their yield factor.
The so-called Fed model postulates that the dividend or earnings yield on stocks equals the yield on nominal Treasury bonds, or at least that they should be highly correlated. Indeed, there is a strikingly high time series correlation between the yield on nominal bonds and the dividend yield on equities. This positive correlation can be traced to the fact that both bond and equity yields comove strongly and positively with expected inflation.
It is now widely accepted that the institutional interventions of states are a foundational influence on the dynamics of organizational forms. But why do states act? In this paper, we apply the behavioral theory of the firm to develop an explanation of state actions based on the fact that they are boundedly rational rivals. The instrument of state competition we examine is the founding of business incubators, a primary tool in the entrepreneurial strategy of economic development.
Although established money managers operate in an environment which seems competitive, they also seem to be very profitable. The present value of the expected future profits from managing a collection of funds is equal to the value of the assets under management multiplied by the profit margin, assuming that the managed funds will remain in business forever, and that there will be zero asset flow into and out of the funds, zero excess returns net of trading costs, a fixed management fee proportional to the assets under management and a fixed profit margin for the management company.
In six experiments, we investigated the role of resource valence in intergenerational attitudes and allocations. We found that, compared to benefits, allocating burdens intergenerationally increased concern with one's legacy, heightened ethical concerns, intensified moral emotions (e.g., guilt, shame), and led to feelings of greater responsibility for and affinity with future generations. We argue that, because of greater concern with legacies and the associated moral implications of one's decisions, allocating burdens leads to greater intergenerational generosity as compared to benefits.
I examine the impact of a property tax relief program in New York State that lowered the marginal cost of school expenditure to homeowners. I find that a typical school district, which received 20% of its revenue through the program in the school year 2001–2002, raised expenditure by 4.1% and local property taxes by 6.8% in response to the program. I then examine how the preferences of various groups of local taxpayers affect educational spending by identifying systematic variation across districts in the response to fiscal incentives.
The present investigation explores the possibility that power has increased salience among males but not females. Evidence indicates that stimuli that are self-relevant or related to chronic goals are more likely to capture attention than neutral information. Across three studies we explore the possibility that the premium males place on power influences how they attend to their environment.
The new challenges that the 21st century brings to the field of marketing competition inspired the International Journal of Research in Marketing (IJRM) to sponsor a special section on the topic. This special section was preceded by a conference at the University of Mainz, co-sponsored by IJRM, MSI, SMU (Singapore) and the University of Mainz.
Five marked evolutions around the turn of the century present new challenges in marketing competition, which may lead to particularly fruitful streams of research.
The present study examined how biculturals (Asian-Americans) adjust to differing cultural settings in performance appraisal. Biculturals vary in the degree to which their two cultural identities are compatible or oppositional — Bicultural Identity Integration (BII). The authors found that individual differences in BII interacted with the manipulation of the cultural setting (American or Asian) in determining whether employee outcomes were evaluated as matching or mismatching cultural norms.
We propose that the reliance on feelings as information in judgment may involve two separate mechanisms: one involves a metacognitive assessment of whether one's feelings should be trusted in the judgment; the other is more mindless reliance on feelings without much consideration for their perceived diagnosticity.
The family-owned Montclair Video attracted loyal customers by providing a wide selection of movies and personalized recommendations, helping it fend off competition from movie-rental giant Blockbuster. That changed with the increasing popularity of Netflix, as well as a rise in on-demand cable content and the introduction of a similar pricing model from Blockbuster. The family was prepared to adopt new pricing and add rental services, but only if the strategy made financial sense.
Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions. Existing studies have however focused exclusively on the U.S.
We review a selected set of tools and frameworks for customer-centric new product development. We structure our review around the typical steps of the new product development process: opportunity identification, idea generation, design, testing, and launch. The list of topics addressed in this chapter is by no means exhaustive. We focus on topics which tend to be more recent and to present opportunities for further development and research.
Particle learning (PL) provides state filtering, sequential parameter learning and smoothing in a general class of state space models. Our approach extends existing particle methods by incorporating the estimation of static parameters via a fully-adapted filter that utilizes conditional sufficient statistics for parameters and/or states as particles. State smoothing in the presence of parameter uncertainty is also solved as a by-product of PL. In a number of examples, we show that PL outperforms existing particle filtering alternatives and proves to be a competitor to MCMC.
In contrast to the view that social perception has symmetric effects on judgments and behavior, the current research explored whether perspective-taking leads stereotypes to differentially affect judgments and behavior. Across three studies, perspective-takers consistently used stereotypes more in their own behavior while simultaneously using them less in their judgments of others. After writing about an African-American, perspective-taking tendencies were positively correlated with aggressive behavior but negatively correlated with judging others as aggressive.
Price discrimination is an extremely common type of pricing strategy engaged in by virtually every business with some discretionary pricing power. The issue of whether price discrimination reduces or increases social welfare has been considered by economists since at least 1920. At that time, it was demonstrated that, under certain (restrictive) conditions, price discrimination will reduce social welfare.
Five studies explored whether power increases moral hypocrisy, a situation characterized by imposing strict moral standards on others but practicing less strict moral behavior oneself. In Experiment 1, compared to the powerless, the powerful condemned other people's cheating, while cheating more themselves. In Experiments 2–4, the powerful were more strict in judging others' moral transgressions but more lenient in judging their own transgressions.
Economics is the study of how scarce resources are allocated. Operations research studies how to accomplish goals in the least costly manner. These fields have much to offer each other in terms of challenging problems that need to be solved and the techniques to solve them. This was the case after World War II, partly because the individuals who went on to be the leading scholars in economics and operations research worked together during WWII. In fact, the two fields share many early luminaries, including Arrow, Dantzig, Holt, Kantorovich, Koopmans, Modigliani, Scarf, and von Neumann.
The preferred risk habitat hypothesis, introduced here, is that individual investors select stocks whose volatilities are commensurate with their risk aversion. The data, 1995-2000 holdings of over 20,000 clients at a large German broker, are consistent with the predictions of the hypothesis: the portfolios contain highly similar stocks in terms of volatility, when stocks are sold they are replaced by stocks of similar volatilities, and the more risk averse customers indeed hold and trade into less volatile stocks.
