David Laibman is Professor Emeritus of Economics at Brooklyn College and the Graduate Center, City University of New York. He received a Ph.D. in Economics in 1973 at the Graduate Faculty of the New School for Social Research in New York. His dissertation, The Invariance Condition for Value-Price Transformation in a Linear, Non-Decomposable Two-Sector Model, dealt with problems in Marxist value theory. Laibman teaches economic theory, political economy, and mathematical economics, at the undergraduate, masters, and doctoral levels at CUNY.
He is also a fingerstyle guitarist, especially its application to the ragtime music of the early twentieth century. With Eric Schoenberg, Laibman recorded The New Ragtime Guitar for Folkways Records in 1970. Rounder Records released his solo album, Classical Ragtime Guitar, in 1980. Laibman has worked with a variety of artists in the early folk world, using his advanced finger picking technique. One notable album is "Way Out West" by Scottish Folksinger Alex Campbell, in 1963. Of note is the track "Orange Blossom Special" which showcases the talent that Laibman was developing.
