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.
This article discusses the underlying dynamics behind the present debate over net-neutrality, analyzes the pro's and con's, concludes that the debate is based on false premises, and proposes a better solution — end-user sovereignty — that is both open and only lightly regulated.
Using the employee opinion survey responses from several thousand employees working in 193 branches of a major U.S. bank, we consider whether there is a distinctive workplace component to employee attitudes despite the common set of corporate human resource management practices that cover all the branches. Several different empirical tests consistently point to the existence of a systematic branch-specific component to employee attitudes.

Research on the relationship between teachers' characteristics and teacher effectiveness has been underway for over a century, yet little progress has been made in linking teacher quality with factors observable at the time of hire. However, most research has examined a relatively small set of characteristics that are collected by school administrators in order to satisfy legal requirements and set salaries.
In this chapter, Kenneth Ayotte and Patrick Bolton model the role that mandatory standardization plays in reducing the costs of financial contracting and improving liquidity. In particular, they identify opportunities for financial contractors to appropriate value from unknowing third parties and show that rules that standardize contracts can serve as a commitment device against such demand-dampening pitfalls facing these other parties. Mandatory standardization thereby can improve the liquidity of secondary markets from loan contracts.
The empty creditor problem arises when a debtholder has obtained insurance against default but otherwise retains control rights in and outside bankruptcy. We analyze this problem from an ex-ante and ex-post perspective in a formal model of debt with limited commitment, by comparing contracting outcomes with and without insurance through credit default swaps (CDS).
Firms in several markets attract consumers by offering discounts in other unrelated markets. This promotion strategy, which we call "cross-market discounts," has been successfully adopted in the last few years by many grocery retailers in partnership with gasoline retailers across North America, Europe, and Australia. In this paper, we use an analytical model to investigate the major forces driving the profitability of this novel promotion strategy. We consider a generalized scenario in which purchases in a source market lead to price discounts redeemable in a target market.
The current studies investigate whether different forms of fatalistic thinking follow from the Christian and Hindu cosmologies. We found that fatalistic interpretations of one's own life events center on deity influence for Christians, especially for those high in religiosity; however, Hindu interpretations of one's own life emphasized destiny as much as deity. Also, the focus on fate over chance when explaining others' misfortunes depends on the presence of known misdeeds for Christians, but not for Hindus.
Estimating the value of top managerial talent is a central topic of research that has attracted widespread attention from academics and practitioners. Yet, testing for the importance of chief executive officers (CEOs) on firm outcomes is challenging. In this paper we test for the impact of CEOs on performance by assessing the effect of (1) CEO deaths and (2) the death of CEOs' immediate family members (spouse, parents, children, etc).
Recent frauds have questioned the efficacy of the SEC's enforcement program. We hypothesize that differences in firms' information sets about SEC enforcement and constraints facing the SEC affect firms' proclivity to adopt aggressive accounting practices. We find that firms located closer to the SEC and in areas with greater past SEC enforcement activity, both proxies for firms' information about SEC enforcement, are less likely to restate their financial statements.
Disparity between control and ownership rights gives rise to the risk of tunneling by the controlling shareholder. This disparity is prevalent in many emerging market economies and present in some developed countries. This paper studies whether and how the degree of control-ownership disparity in investors' home countries affects their portfolio choice in an emerging market. It combines two unique data sets on ownership and control in business groups, and investor-stock level foreign investment in Korea.
Social power, alcohol intoxication, and anonymity all have strong influences on human cognition and behavior. However, the social consequences of each of these conditions can be diverse, sometimes producing prosocial outcomes and other times enabling antisocial behavior. We present a general model of disinhibition to explain how these seemingly contradictory effects emerge from a single underlying mechanism: The decreased salience of competing response options prevents activation of the Behavioral Inhibition System (BIS).
This paper shows that Chief Executive Officers (CEOs) meaningfully affect firm performance. Using variation in CEO exposure resulting from the numer of days a CEO is hospitalized, we provide estimates of the effect of CEOs on firm policies, holding firm and CEO matches constant. We have four main findings. First, CEOs have an economically and statistically significant effect on profitability, revenue, and investment outcomes. Firms whose CEOs are hospitalized underperform when their chief executives are sick but otherwise exhibit similar performance relative to other firms.
What do economics and history have to tell us about the ways euro zone countries are likely to resolve their problems of fiscal unsustainability and banking system insolvency? In answering that question, I am among the most pessimistic observers of the likely future of the euro and its membership. In my view, the euro zone's likely failure to avoid at least some departures, if not total collapse, reflects its poor initial institutional design.
Experience is a new and exciting concept marketing academia and practice. This monograph reviews the various meanings of experience as the term is used in philosophy, psychology, and in consumer behavior and marketing. I will discuss the key concepts of experience marketing such as experiential value, different types of experiences, the distinction between ordinary and extraordinary experiences and experience touchpoints.
Financial openness is often associated with higher rates of economic growth. We show that the impact of openness on factor productivity growth is more important than the effect on capital growth. This explains why the growth effects of liberalization appear to be largely permanent, not temporary. We attribute these permanent liberalization effects to the role financial openness plays in stock market and banking sector development, and to changes in the quality of institutions. We find some indirect evidence of higher investment efficiency post-liberalization.
Campbell et al. (2001) document that firms' stock returns have become more volatile in the U.S. since 1960. We hypothesize and find that deteriorating earnings quality is associated with higher idiosyncratic return volatility over 1962–2001.
While millions of products are sold on its retail platform, Amazon.com itself stocks and sells only a very small fraction of them. Most of these products are sold by third-party sellers who pay Amazon a fee for each unit sold. Empirical evidence clearly suggests that Amazon tends to sell high-demand products and leave long-tail products for independent sellers to offer.
We consider the Kiefer-Wolfowitz (KW) stochastic approximation algorithm and derive general upper bounds on its mean-squared error. The bounds are established using an elementary induction argument and phrased directly in the terms of tuning sequences of the algorithm. From this we deduce the non- necessity of one of the main assumptions imposed on the tuning sequences in the Kiefer-Wolfowitz paper and essentially all subsequent literature.
This research examines how consumers' spending on themselves versus others can be affected by temporary shifts in their states of power. Five experiments found that individuals experiencing a state of power spent more money on themselves than on others, whereas those experiencing a state of powerlessness spent more money on others than on themselves. This effect was observed using a variety of power manipulations (hierarchical roles, print advertisements, episodic recall, and mental role-playing), across spending intentions and actual dollars spent, and among college and national samples.
A major governance problem in closely-held corporations arising from the illiquidity of shares is the majority shareholders' expropriation of minority shareholders. As a solution, legal and finance research recommends that the main shareholder surrender some control to minority shareholders via ownership rights. We test this proposition on a large dataset of closely-held corporations. We find that shared-ownership firms report substantially larger return on assets (up to 14 percentage points) and lower expense-to-sales ratios.
This guest editorial of JAR considers what the "new normal" of marketing will be and suggests that it will be the digitization of everything, the need for constant change and adaptation affected by the continuous flow of knowledge. Involving consumers in co-creation will be increasingly important, while raw data for market research has increased massively and so will require the tools and people to mine it.
The past 25 years have represented two periods of extreme movements in U.S. and global house prices that appear to be much larger than can be easily explained by changes in fundamentals. These episodes spurred research on housing bubbles that focused attention on the role of outsized expectations in excessive house price appreciation. By contrast, some economists pointed to alternative explanations for excess volatility, including liquidity constraints, lending cycles, search externalities, and zoning delays.
In many service industries, companies compete with each other on the basis of the waiting time their customers experience, along with other strategic instruments such as the price they charge for their service. The objective of this paper is to conduct an empirical study of an important industry to measure to what extent waiting time performance impacts different firms' market shares and price decisions.
The current research explored whether sharing intentionality leads to implicit coordination, a situation in which isolated individuals independently adopt a similar standard of behavior. We propose that knowing that a given goal is experienced in common with other in-group members or similar others intensifies goal pursuit. Two experiments examined whether simply being aware that one's own individual goal was also being separately pursued by similar others results in more goal-congruent behavior.
It is important to understand the factors that influence a country’s transition from the production of low-quality to high-quality products since the production of high-quality goods is often viewed as a pre-condition for export success and, ultimately, for economic development. In this paper, we provide the first evidence that countries’ import tariffs affect the rate at which they upgrade the quality of their products. We analyze the effect of import competition on quality upgrading using highly disaggregated export data to the U.S.
Will Rogers, commenting on the Depression, famously quipped: "If stupidity got us into this mess, why can't it get us out?" Rogers's rhetorical question has an obvious answer: persistent stupidity fails to recognize prior errors and, therefore, does not correct them. For three decades, many financial economists have been arguing that there are deep flaws in the financial policies of the U.S.
We investigate firms that stop providing earnings guidance ("stoppers") either by publicly announcing their decision ("announcers") or doing so quietly ("quiet stoppers"). Relative to firms that continue guiding, stoppers have poorer prior performance, more uncertain operating environments, and fewer informed investors. Announcers commit to non-disclosure because they (i) do not expect to report future good news or (ii) have lower incentives to guide due to the presence of long-term investors. The three-day return around the announcement is negative.
Cross-national research on social description documents that Westerners favor abstract linguistic categories (e.g., adjectives rather than verbs) more than East Asians. Whereas culture-related schemas are assumed to underlie these differences, no research has examined this directly. The present study used the cultural priming paradigm to distinguish the role of cultural schemas from alternative country-related explanations involving linguistic structures or educational experiences.
This case introduces students to GM’s partnership with Toyota in the NUMMI joint venture in order to analyze the challenges GM might face in implementing this approach more broadly. Students consider the evolution of lean operations and its various elements. The case focuses on the Toyota Production System, its benefits and related flexibility. What are the potential implications of the analysis for GM’s production strategy and profitability?
We propose a distinction between two types of interpersonal compatibility in determining partner preferences for joint tasks: outcome compatibility and strategic compatibility. We argue that these two types of compatibility correspond to preferences for similar and complementary task partners, respectively. Five studies support this distinction.
Building on his expertise in macroeconomic policymaking at the Federal Reserve, Mishkin's Macroeconomics: Policy and Practice text clearly provides a theoretical framework that illustrates the most current and relevant policy debates in the field.
Managing Change: Cases and Concepts, 3e by Todd Jick and Maury Peiperl is comprised of six modules that introduce common threads in the ensuing case studies and readings on organizational change. The materials in this edition — cases and readings — have been chosen and arranged to introduce change as an integrated process. Cases in the text represent a wide variety of change situations. Accompanying many cases are readings, likewise chosen to reflect a broad range of issues.
In 5 studies, we investigated the relation between regulatory focus and the tendency to copy a role model’s managing behavior after one experiences this behavior as its recipient and later takes on the same managing role. Because enacting role-related behaviors fulfills interpersonal norms that fit prevention concerns, we predicted a stronger tendency to copy among individuals with a stronger prevention focus on duties and obligations (“oughts”) but not among those with a stronger promotion focus on aspirations and advancements (ideals).
This paper examines what we have learned about monetary policy strategy and considers how we should change our thinking in this regard in the aftermath of the 2007–09 crisis. It starts with a discussion of where the science of monetary policy stood before the crisis and how central banks viewed monetary policy strategy. It then examines how the crisis has changed the thinking of both macro/monetary economists and central bankers. Finally, it looks at what implications this change in thinking has had for monetary policy science and strategy.
