Inflated ‘Private’ Ratings Are Masking Credit Risk, Columbia Study Says

Expertise in credit rating agencies, private credit markets, insurance regulation, and the measurement of credit risk. Our research shows that private ratings are systematically more inflated and less accurate than public ratings, allowing credit risk to be understated in regulated insurance portfolios. .faculty-items { display: grid; } @media (min-width: 1024px) { .faculty-items { grid-template-columns: repeat(3, 1fr); } } .m-listing-faculty, .m-listing-pgprofile { flex-direction: column; }

New York and Chicago Haven’t Escaped the Urban Doom Loop

Columbia Business School's Professor Stijn Van Nieuwerburgh and NYU Stern's Professor Arpit Gupta were featured in a Bloomberg Opinion column examining the post-pandemic urban doom loop — a concept Van Nieuwerburgh coined and introduced in the landmark paper "Work from Home and the Office Real Estate Apocalypse," now published in the American Economic Review. In the piece, Van Nieuwerburgh warns that New York City faces deep fiscal trouble, citing an effective doubling of office property tax rates and no clear path to financial health. Gupta traces the historical roots of urban flight while noting encouraging signs in New York's office-to-apartment conversion pace. Both researchers see the doom loop as a continuing risk, driven by falling commercial real estate values, shrinking tax revenues, and the enduring shift to remote work — and underscore that while the economic fixes may be straightforward, the political will to implement them remains the critical missing ingredient.

Canadian Companies Need Cash. Is a Sovereign Wealth Fund the Answer?

Columbia Business School’s Professor Brett House authored an op-ed in Maclean’s analyzing Canada’s Canada Strong Fund (CSF). In the piece, House explores whether the $25-billion fund—a government initiative to retain capital and investment in Canadian companies—can effectively address the country’s economic challenges. He highlights concerns about the fund’s structure, its reliance on government borrowing, and its potential to keep Canadian businesses from seeking foreign investment. House also emphasizes the need for broader reforms in trade, immigration, and procurement to complement the CSF’s goals.
