WASHINGTON - Venture capitalist Marc Andreessen, economist Raj Chetty and former Bank of England governor Mervyn King number among appointees unveiled by the Federal Reserve on Thursday to propose updates to the central bank's practices.

They serve as co-leaders of five task forces that Fed Chair Kevin Warsh introduced last month. The remaining leaders blend public officials with business executives.

Warsh advocated for regime change at the Fed last year during consideration by the Trump administration to succeed former chair Jerome Powell. He has pushed for less communication on interest rate views and called for shrinking the central bank's roughly $6.7 trillion holdings of government bonds.

Still, the potential impact of these task forces remains uncertain. Most directors named Thursday rank as established voices in economics and business instead of longtime Fed critics. Observers note that Warsh appears to favor persuading colleagues through these groups rather than mandating shifts outright.

The U.S. economy has evolved markedly over the past generation, and especially so at present, Warsh stated in writing. Each task force will review whether policymakers tools, methods and approaches warrant refinement.

The five task forces will each feature three co-leaders backed by Fed staff, the central bank noted.

One group will study how artificial intelligence and emerging technologies shape productivity and employment. Warsh has often highlighted expectations that AI will drive major economic shifts.

To lead that effort, Warsh selected executives from AI-focused firms, including Marc Andreessen, a prominent backer of crypto and AI ventures. Asha Sharma, executive vice president at Microsoft and head of its Xbox division, joins as co-leader. Stanford economist Charles Jones, currently on leave at Anthropic, serves as the third co-chair.

Chetty, the Harvard economist, will co-lead a group examining data sources relied upon by the Fed. He has pioneered use of large datasets to follow family economic trajectories over time and assess regional differences in mobility.

Doug McMillon, former Walmart president and CEO, and University of Chicago economics professor Kevin Murphy will also co-lead the data task force.

A separate task force will review the Fed balance sheet, which expanded sharply after the 2008-2009 Great Recession. Former Reserve Bank of India leader Raghuram Rajan, Harvard economist and ex-Treasury official Karen Dynan, and one-time Fed governor Jeremy Stein will co-lead that group.

Greg Mankiw, a leading economist from the George W. Bush administration, and Nobel laureate Thomas Sargent of New York University will co-lead a task force on inflation frameworks. King, the ex-Bank of England governor, will help lead the communications task force.
