AMEC Symposium on “The K-Shaped Economy”

April 03, 2026
On April 3, 2026, the Federal Reserve Bank of New York hosted a hybrid symposium titled “The K-Shaped Economy.” The goal of the symposium, which was organized by the New York Fed's Applied Macroeconomics and Econometrics Center (AMEC), was to stimulate debate among academics, practitioners, and policymakers. The event included presentations, followed by Q&A, on key issues, ideas, and research on the K-shaped economy and specifically on the evidence of divergence in micro-level and asset markets data and the implications of this divergence for macroeconomic dynamics and monetary policy.

Agenda
Agenda
9:40am Introduction: Marco Del Negro (New York Fed) (00:00:15 in video)
9:45am–11:00am Session 1: Micro-level evidence of a K-shaped economy (00:04:06 in video)


Is there any evidence of a K-shaped economy in micro-level data---that is, is the economy splitting into two tiers, with AI or other forces creating diverging outcomes for the wealthy compared to others? Have consumption and labor market outcomes evolved differently for individuals at different points in the income and wealth distribution in recent years? Is there evidence of bifurcations by other demographic attributes, such as by age, gender or race? How have the social safety net and other policies affected recent trends in income, consumption and/or wealth inequality, and what policies (if any) could reverse these trends? What types of occupations and workers might be disproportionately affected by the growth of AI in the short, medium and long term? How might AI reshape the future income and wealth distribution?

Chair: Rajashri Chakrabarti (New York Fed)

Panelists: Martha Gimbel (Yale University, Budget Lab) | Presentation
Pascal Noel (University of Chicago, Booth) | Presentation
James Ziliak (University of Kentucky) | Presentation 
11:15am–12:30pm Session 2: Diverging asset markets (01:23:39 in video)


Is concentration in stock market gains, such as that currently among the “Magnificent 7,” a common feature of markets during episodes of technological innovation? What are the financial stability implications of such bifurcated asset markets? Are asset price booms associated with periods of technological innovation confined to equity markets or are they also present in debt markets? What metrics may be used to evaluate whether asset valuations reflect fundamentals or excess exuberance during such periods? Can we identify likely turning points in the valuations cycle? Does the increased concentration of stock market gains imply that recessions need no longer be associated with stock market declines?

Chair: Nina Boyarchenko (New York Fed)

Panelists: Krishna Guha (Evercore ISI) | Presentation
Markus Brunnermeier (Princeton University) | Presentation
Samuel Hanson (Harvard Business School) | Presentation 
12:30pm–1:30pm Lunch
1:30pm-2:45pm Session 3: Implications of the K-shaped economy for macroeconomic dynamics and monetary policy (02:39:03 in video)


To what extent has GDP growth in recent years been driven by the spending of high-income households and by investment in AI? What effect will advances in AI have on productivity growth and the distribution of income? What are the implications of increasing consumption, income and wealth inequality for macroeconomic dynamics? Is wealth inequality a consequence of the divergence between asset valuations and the macroeconomy, or also a source of this divergence? Do recent trends in inequality have any implications for the conduct or transmission of monetary policy?

Chair: Keshav Dogra (New York Fed)
