Steve Randy Waldman (born 1970) is a computer programmer and writer known for his commentary on contemporary economics at his blog Interfluidity. Educated at the New College of Florida, and University of Kentucky,^[1] Waldman is a Java programmer and wrote the c3p0 tool. He is most well known for his economics posts at Interfluidity, which have been cited by Paul Krugman,^[2] Tyler Cowen,^[3] Simon Wren-Lewis,^[4] The Economist,^[5] CNBC,^[6] the National Review,^[7] Justin Fox of Time magazine,^[8] and Matt Levine.^[9] Waldman supports a basic income^[10] (or other ways to provide a strong social safety net) and otherwise describes himself as "Danish libertarian".

Waldman is known for his criticism of financial regulation:^[11] James Kwak quotes "An enduring truth about financial regulation is this: Given the discretion to do so, financial regulators will always do the wrong thing."^[12] Paul Krugman of the New York Times often cites Waldman; he talks about him 'going medieval' on Ezra Klein,^[13] and another time: "we are indeed, as Steve Randy Waldman says, all dorks".^[14]

The writer and novelist Adelle Waldman^[15][16] is Waldman's sister. His mother, Jacqueline Waldman, was a chemistry professor at Goucher College.^[17]
