Leading Insights Landing Image

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.

The End of Tourist Traps: A Natural Experiment on the Impact of Tripadvisor on Quality Upgrading

Author

Asymmetric information can distort market outcomes. I study how the online disclosure of information affects consumers’ behavior and firms’ incentives to upgrade product quality in markets where information is traditionally limited. I first build a model of consumer search with firms’ endogenous quality decisions. In this model, lower search costs reallocate demand toward higher-quality producers, raising firms’ incentives to upgrade quality, and more so for firms selling ex-ante lower-quality products.

Toward a Pedagogy for Consumer Anthropology: Method, Theory, Marketing

This paper focuses on teaching the application of anthropology in business to marketing students. It begins with the premise that consumer marketers have long used ethnography as a component of their qualitative market research toolkit to inform their knowledge about and empathy for consumers. A question for market research educators who include ethnography in their curricula is if and how to teach the richness of anthropologically based approaches, especially given a decoupling of ethnographic method from anthropological theory in much consumer research practice.

Diversity initiatives in the US workplace: A brief history, their intended and unintended consequences

Author
Portocarrero, Sandra and James Carter

Diversity initiatives are designed to help workers from disadvantaged backgrounds achieve equitable opportunities and outcomes in organizations. However, these programs are often ineffective. To better understand less-than-desired outcomes and the shifting diversity landscape, we synthesize literature on how corporate affirmative action programs became diversity initiatives and current literature on their effectiveness. We focus specifically on work dealing with mechanisms that make diversity initiatives effective as well as their unintended consequences.

Where Has All the Data Gone?

Author
Farboodi, Maryam, Adrien Matray, Laura Veldkamp, and Venky Venkateswaran

As financial technology improves and data becomes more abundant, do market prices reflect this growing information and allocate capital more efficiently? While a number of recent studies have documented rises in aggregate price efficiency, we show that there are large cross-sectional differences. The previously-documented increases are driven by a rise in the informativeness of large, growth stocks. The informational efficiency of smaller assets' prices or prices of assets with less growth potential are either flat or declining.

“Invisible” Discrimination: Divergent Outcomes for the Nonprototypicality of Black Women

Author
Ponce de Leon, Rebecca and Ashleigh Shelby Rosette

By integrating the intersectional invisibility hypothesis with the behaviors from intergroup affect and stereotypes map framework, we examine the extent to which Black women’s dual-subordinated identities render them nonprototypical victims of discrimination, relative to White women and Black men, and the corresponding consequences.

Crypto and meme corporate bonds may follow their own path

Author

The crash of some of the flagbearers of the equity bubble in recent years has been painful for investors. We have seen “pandemic winner” Netflix dive 75 per cent from 2021 peaks, crypto exchange operator Coinbase plunge 86 per cent and the one-time meme stock and cinema chain AMC lose 80 per cent.

Bond Convenience Yields in the Eurozone Currency Union

Author
Jiang, Z., H. Lustig, Stijn Van Nieuwerburgh, and M. Xiaolan-Zhang

In a monetary union, the risk-free rate cannot respond to country-level fiscal shocks, leaving only default spreads and convenience yields to respond. Empirically, we find that convenience yields play an important role as fiscal shock absorbers in the Eurozone. Consistent with downward-sloping demand for safety, Eurozone countries earn larger convenience yields after they release positive fiscal news.

Man vs. Machine: Quantitative and Discretionary Equity Management

Author

In modern asset markets, man and machine compete for profits. How does each fare? I build a learning model in which quantitative investors (reliant on computer models) have more learning capacity but less flexibility to adapt to market conditions than discretionary investors (reliant on human judgment). I use machine learning to categorize US active equity mutual funds as quantitative or discretionary. Consistent with the model's predictions, I find that quantitative funds hold more stocks, specialize in stock picking, and engage in more overcrowded trades.

Bank Liquidity Provision across the Firm Size Distribution

Author
Chodorow-Reich, Gabriel, Olivier Darmouni, Stephan Luck, and Matthew Plosser

We use supervisory loan-level data to document that small firms (SMEs) obtain shorter maturity credit lines than large firms, post more collateral, have higher utilization rates, and pay higher spreads. We rationalize these facts as the equilibrium outcome of a trade-off between lender commitment and discretion. Using the COVID recession, we test the prediction that SMEs are subject to greater lender discretion. Consistent with this hypothesis, SMEs did not draw down whereas large firms did, even in response to similar demand shocks.
