Jason M. Barr is an American economist and author at Rutgers University-Newark, whose work is in the field of "skynomics", the study of skyscrapers and skylines using modern economics methods. He is the author of Building the Skyline: The Birth and Growth of Manhattan's Skyscrapers, which chronicled the history of the Manhattan skyline from an economic perspective. Barr's work is interdisciplinary and integrates multiple disciplines including urban studies, geography, and economic history. Barr is one of the few economists studying the intersection of economics and skyscraper construction.

The design and construction of skyscrapers involves creating safe, habitable spaces in very high buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among the most complex encountered given the balances required between economics, engineering, and construction management.
