Using AI at work in the wrong ways could lead to falling behind and becoming complacent, according to Sandra Matz, a professor at Columbia Business School.

Columbia Business School professors analyze a World Cup match incident involving Folarin Balogun to illustrate how AI handles measurable decisions versus those requiring human judgment. The article contrasts an uncontested AI-assisted offside call with a controversial red card decision, emphasizing that while routine decisions can be automated, complex judgments still require human oversight.

A study by Len Sherman of Columbia Business School found Uber's insurance and operational fees varied between $13.75 and $50 on similar 60-mile trips, with Uber attributing the variation to factors like origin city and time of day. Uber explains these fees cover government-mandated insurance and operational costs, which are estimated and not tied to individual trip expenses.

A tentative deal to end the Iran war may not immediately lower consumer prices, as experts predict lingering high costs due to disrupted supply chains and delayed oil price effects. Economists note that even with reduced oil prices, refineries' advance crude oil payments will delay cheaper products for consumers.

A tentative U.S.-Iran deal to end the war may not immediately lower gas, grocery, and flight prices. Experts note delays due to pre-paid oil contracts, refining processes, and airline fuel agreements, with some regions facing prolonged impacts from disrupted supply chains.

A tentative U.S.-Iran deal to end conflict is unlikely to immediately lower gas, grocery, and flight prices due to delayed supply chain adjustments and pre-purchased fuel contracts. Experts warn higher costs will persist for weeks or months as systems adapt to restored oil flows and disrupted logistics.

A tentative deal to end the Iran war may not immediately lower gas, grocery, and flight prices. Experts say supply chain disruptions and pre-purchased fuel contracts will delay price reductions, with some regions facing prolonged higher costs.

A tentative deal to end the Iran war may not immediately lower gas, grocery, and flight prices, as experts warn that higher costs will persist due to delayed oil price adjustments, disrupted supply chains, and pre-purchased fuel contracts. Businesses and consumers should prepare for lingering elevated expenses despite the conflict's resolution.

A tentative U.S.-Iran deal may end the war, but experts warn higher gas, grocery, and flight prices will persist due to disrupted supply chains and delayed market adjustments. Oil prices have fallen, but refineries and airlines operate on long-term contracts, slowing consumer relief. Businesses expect elevated costs to linger, impacting global markets.

Experts say higher prices for gas, groceries, and flights will persist even after a tentative Iran war deal due to supply chain disruptions and advance contracts. Oil and fuel price reductions will take weeks or months to reach consumers, with regional and global factors delaying recovery.

SpaceX CFO Bret Johnsen has focused on securing launch capabilities and reducing orbital costs, while Starlink now serves 10 million customers across 160 countries. The company’s $75 billion IPO values it at $1.8 trillion, but CFO Johnsen faces challenges in proving the value of SpaceX’s conglomerate structure to investors.

A study by Len Sherman of Columbia Business School found Uber's take rate in ride-hailing fares has risen above 50% in some cities, up from 15-20% a decade ago. Uber disputes the findings, claiming an average take rate of 21% in Q3 2025. The analysis tracked three drivers' data across Dallas, Miami, and Tampa over nine years.

AI is disrupting the job market by enabling candidates to use AI tools for resume writing and interview preparation, making it difficult for employers to assess genuine skills. This has led to homogenized applications, increased fraud, and an 'arms race' between AI-powered hiring tools and cheating detection systems.
