The wizardry of ChatGPT captured the world’s attention when it was released in 2022 and became the most successful product launch in history. Since then, AI companies and startups have attracted billions in new investments, and the technology has continued to dazzle. Consumer-facing AI programs can now compose love ballads—or fabricate realistic video of cowboys riding unicorns and shooting water pistols—from simple text prompts. There are uncountable reasons to be…

Revenue fraud—when a company artificially inflates its revenue to meet investors’ expectations—can wreak havoc on financial markets, which rely on accurate information to function properly. In recent years, scholars have attempted to improve fraud detection methods by using machine learning, statistics, and even vocal emotion analysis software, which analyzes the speech of corporate executives on earnings calls. Yale School of Management Professor X. Frank Zhang and two co-authors have a…

Economic inequality continues to widen—and not just between people, but between places, too. The United States, for example, has seen a regional divergence since the 1970s, when the country began transitioning away from heavy manufacturing and toward a service-based economy, resulting in dampened economic prospects and living standards throughout the Rust Belt. The widening chasm between richer and poorer regions has motivated policymakers in multiple countries to offer incentives, like…

Howie and Harlan are joined by Robert Alpern, a Yale nephrologist and the former dean of the Yale School of Medicine, to discuss the importance of a fiscal base for enabling a medical school to deliver top-quality training, research, and clinical care. Harlan asks whether widespread norovirus is a reason to call it quits on shaking hands. Howie reports on a study of the increased mortality among those with ADHD.…

In the spring of 2022, a team of economists and public health researchers led by Mushfiq Mobarak, Niccolò Meriggi, and Maarten Voors spent weeks bumping along rough, gullied roads in rural Sierra Leone. It was hot and humid, but at least it was the dry season: Sierra Leone has the highest annual precipitation in West Africa, and most roads are unpaved, so when the downpours come, the roads become mud-slathered,…

Howie and Harlan are joined by Robert Rohrbaugh, professor of psychiatry and deputy dean for professionalism and leadership at the Yale School of Medicine, to discuss his work training doctors in antiracist practices and ensuring the wellbeing of clinicians during the pandemic. Harlan reports on the problematic history of medical journals promoting eugenics; Howie highlights a cyberattack that has paralyzed Change Healthcare, the country’s largest payments processing hub. Links: Antiracist…

Harlan Krumholz: Welcome to Health & Veritas. I’m Harlan Krumholz. Howard Forman: And I’m Howie Forman. We’re physicians and professors at Yale University. We’re trying to get closer to the truth about health and healthcare. Harlan and I have intentionally set aside several episodes each year to cover a broader range of important news in the healthcare and health realm. And so I want to start off today with something…

With the new year comes our annual tradition of recognizing three CEOs for their accomplishments over the last 12 months—as well as three CEOs who are on the hot seat after a year of struggles. Such an effort at accountability can teach us a lot about the future, as glancing backward is often a valuable guide to the path forward. While there can be surprise technological and market disruptions, classical…

Sometimes, political reporters without a background in business journalism make egregious errors in their coverage of the business exodus from Vladimir Putin’s Russia—and even fall for the strongman’s Potemkin Village-like economic façade. A recent article, entitled “How Putin Turned a Western Boycott Into a Bonanza”, wrongly suggested that the historic business exits of over 1,000 multinational companies from Russia have somehow been a huge win for the Russian war effort,…

Should we hold accountable companies that fail to meet their climate commitments? There is important research by Professor Kelly Shue that shows in some cases, investing in “brown firms”—or firms that are transitioning to lower emissions in greenhouse gas-intense sectors—has a greater benefit to the environment than investing in firms that are already green with low emissions. So we need to be smart about which GHG emissions commitments of net-zero…

Today, the images and videos circulating, especially across social media, are offering a very poor representation of the truth of what happened on October 7 in Israel. This is partly due to the Israeli government’s understandable efforts to protect the privacy and dignity of the victims, and abstaining from publishing evidence of the atrocities committed to the public. At the same time, the content that is flooding social platforms now…

Q: What’s the state of the art market? Over the last decade, the size of the art market has maintained a relatively constant level, remaining close to the $60 billion mark. Although this seems like a large number, it significantly falls short when compared to FedEx’s revenue, which exceeded $90 billion last year. So all participants in the art world, including auction houses, galleries, and art advisors, collectively generate less…

Amid heightened fears of a wider conflict in the Middle East, our focus must turn to deterring and punishing terrorist aggressors in the region, led by Iran, instead of trying to appease the terrorists by making dangerous concessions. Oil represents the best leverage over Iran, even though it has been overlooked by media commentators, and strengthening sanctions on Iranian oil can help preserve peace. Iran is driving the Middle East…

The theory has held for decades: give people a choice and you’re also giving them an illusory sense of control. For example, a much-cited 1975 study found that if people are allowed to pick the numbers on a lottery ticket rather than having them randomly assigned, they’re more likely to think their ticket will win—even though every ticket carries the same odds. “We didn’t start our project questioning this assumption,”…

As computers evolved from room-sized contraptions wrangled by specialists to machines that displaced typewriters on more and more desks, the change was met with excitement, anxiety, hype, and skepticism. Workers feared being replaced by machines; managers weren’t sure, despite the eyewatering expense of equipping everyone with a computer, whether the devices actually made workers more productive. Today, businesses face a similar choice. A nascent, probably transformative technology is emerging. Generative…

Q: You are two of the co-authors of a paper, “The Bias Time Out: A Practical Tool for Advancing DEIB in the Healthcare Space” that proposes a real-time process for reducing errors and negative outcomes due to bias. How did you develop this tool? Dr. Cecelia Calhoun: Five of us came together as clinical and administrative healthcare leaders. We shared stories about our work in care delivery, hospital management, workforce…

Last week, three questions dominated the coverage of indefatigable Ukrainian President Volodymyr Zelensky’s high-profile visit to the United Nations in New York and meetings with President Joe Biden and bipartisan legislators in Washington: How much longer will this war last? How will it end? And what are Ukraine’s prospects as a society afterward? Freshly back from a visit to Kyiv sponsored by the Victor Pinchuk Foundation’s Yalta European Strategy forum,…

As anyone who is planning to move to a new city or neighborhood with a school-aged child knows, not all public schools are created equal. Some have shinier athletic facilities or bigger classrooms or newer equipment in the science and computer labs, all indications to anxious parents that their children will receive a superior education, which will better equip them to prosper and succeed in life. New athletic fields and…

Q: In 2012, you and Yvon Chouinard co-authored The Responsible Company: What We’ve Learned from Patagonia’s First 40 Years. Now, you have released The Future of the Responsible Company: What We’ve Learned from Patagonia’s First 50 Years. Why the new book?   So much of what is going on in the world is heartbreaking and scary. But there’s also so much learning going on. We now have the potential to…

  The Horatio Alger Myth has resurfaced in headlines this summer in political controversy that shows little insight into the true character behind this myth of American success. Alger was a scandalized failure whose recreated image was later manufactured by publicity seeking publishers in the 1920s several decades after his death. Is that really something partisans of either persuasion should celebrate? The failed writer Horatio Alger of the 19th century…

On average, women earn 79 cents on the dollar compared to men—a figure that has been repeated by economists and politicians for years. It has proven a simple way to underscore a persistent and complex problem in the United States. Although factually correct, the finding that women make less than 80% of what men do doesn’t tell the full story about gender in the workplace. Mushfiq Mobarak, professor of economics,…

The last time we talked about returning to the office, you suggested that we take this opportunity to think about the workplace—not just how to organize workers and cubicles, and whether we mask, and what the hybrid policy is, but to assess how our organization works, and how we‘re working together as a team. Now it’s 2023. Do you think that those conversations are still needed? Absolutely. For the most…

In early 2020, as restrictions imposed to contain the coronavirus swept across the world, concerns about “lockdown fatigue” followed closely in their wake. As early as spring and early summer in the U.S., media commentators worried that lockdown policies were chafing, and that a critical mass of weary rule-breakers could render such policies ineffective. But were the fears about the diluting effects of lockdown fatigue warranted? After all, it was…

Cynics often know the price of everything but the value of nothing. Remember how, just months ago, leading economic voices were predicting a catastrophic “Category 5 economic hurricane” this year? The astounding 2.4% GDP growth revealed this week, with plunging inflation, historically low unemployment, and corporate profit reports soaring past expectations, have knocked the wind out of the fact-free cynics. It’s been said that cynics sound smarter than optimists because…

Q: Are there key questions that have guided your career? All my research looks at judgment and decision making. I’ve done work on couples’ financial behavior. I’ve looked at how emotion influences our perception of risk. I’m quite interested in our moral intuitions and how they align with our actual behavior. Right now, I’m doing research on how people evaluate moral transgressions. But, over the course of my career, the…

The headlines are full of grand and sometimes terrifying speculation about the potential of artificial intelligence. At Yale SOM’s CEO Summit recently, Prof. Jeffrey Sonnenfeld asked business leaders for some real talk about how their companies are using the technology. Jeffrey A. Sonnenfeld Senior Associate Dean for Leadership Studies & Lester Crown Professor in the Practice of Management Steven Tian Director of Research, Chief Executive Leadership Institute Amidst all the…

Cryptocurrencies are notoriously volatile. But listening carefully to social media chatter can help identify winning short-term investments in crypto, according to a new Yale study carried out as the crypto bubble expanded and finally popped. The methodology in the study, co-authored by Prof. Tauhid Zaman and PhD student Khizar Qureshi, could also be used to translate online buzz into predictions in other domains. Written by Dylan Walsh As cryptocurrency soared…
