The following message was sent to the Columbia Business School Community on October 10, 2023.
"The decline in moviegoing is part of a larger trend of staying in – a trend that began before the pandemic. This suggests that consumers' preferences are changing, and that the movie industry needs to innovate to address new needs. Doubling down on the same strategy might prove fruitless."
- Professor Melanie Brucks
"While many will point to the consumer, their “back to basics” is a large part of their performance. After their troubles (and substantial fine by OSHA), the retail brand needed to re-focus their efforts to examine the performance of their stores, invest in their store employees, and ensure that their processes were meeting the retailer’s strategic objective. They put in place a lot of talent in terms of store operations."
- Professor Nicole DeHoratius
"In principle, ILC can really help the economy: these firms often have good knowledge of borrowers, and investment needs that can be harder for banks to know well. The view that banks are experts at collecting and processing information is outdated in the new economy. Heavy regulation is warranted for banks that handle household savings, but that also clearly hampers their ability to serve some borrowers."
- Professor Olivier Darmouni
"As you said, people want simplicity, a one-stop shop. So, I think OpenAI is well positioned there because ChatGPT can text and solve different problems. They keep adding modalities to Chat GPT. I think Chat GPT has been able to brand itself – it’s like a new word in the dictionary, almost. And so they, from the branding perspective, I think they are the main guys. People associate Open AI with almost like a Google search. So I think from that perspective, the branding around the founder, the company. And in the US, at least, Google has the integration feature, which is useful. So, I think, to me, OpenAI is pretty well positioned at this point. I think DeepSeek made a lot of noise, but I don’t think it’s going to become a major player in the US quite yet."

Gernot Wagner on why the EV market slump is caused by politics and optics spurred by Elon Musk, "This isn’t an EV market problem. It’s an Elon Musk problem. What’s happening here, you can probably explain through the politics and the optics. Tesla stock exploded after the November election because of Elon Musk’s proximity to President Donald Trump. That proximity has not turned into Tesla sales, at least not yet, and maybe never."
Professor Tomasz Piskorski on the Rocket-Redfin deal, "Everybody in this industry is going for the holy grail of what we call digital closing. Buying a home has typically involved a fragmented process. From start to finish, it involves an array of actors, including title companies, real estate agents, mortgage brokers, and insurance companies. Bringing these entities together on one platform would make the home-buying process not only less complicated, but also much faster. Everybody wants to be the Amazon of real estate, where a prospective buyer can purchase a home with the click of a button. But if there is too much concentration in the industry," it raises the question of whether a buyer is getting a fair deal. The convenience promised by the merger could also lead to an increase in home prices.
Professor Rebecca Ponce de Leon on how DEI rollbacks impact consumer sentiment, "If brands turn their backs on previously made dedications, they could face reputational risk that tends to stick with them long after the political climate changes. Just because a company has released a statement talking about injustice against marginalized groups or has donated money towards a cause will not necessarily improve its ranks amongst consumers unless people can also trust that these types of actions are likely to continue over time, when the specific moment has passed, and it’s no longer prescribed."
Professor Brett House on the Federal Reserve holding interest rates, "Tariffs on aluminum, steel, and oil are essential elements to production across a wide range of products. Those price increases are going to ripple more widely across the American economy. The inflation risk from tariffs ensured the central bank would take a more cautious approach. Greater uncertainty in the world means the Fed is more predictably in a wait-and-see mode."
Professor Netzer's expertise centers on one of the major business challenges of the data-rich environment: developing quantitative methods that leverage data to gain a deeper understanding of customer behavior and guide firms' decisions. He focuses primarily on building statistical and econometric models to measure consumer preferences and understand how customer choices change over time, and across contexts. Most notably, he has developed a framework for managing firms' customer bases through dynamic segmentation.
