Does &quote;Trickle Down&quote; Work?

Persky, Felsenstein, and Carlson explore a new framework for evaluating state and local economic development efforts. They propose a method, referred to as the &quote;job-chains approach,&quote; that they say clarifies the potential justifications for economic development subsidies as well as the limitations surrounding these efforts. This innovative approach addresses not only the number of job vacancies created as a result of a subsidized business investment or expansion, but also the extent to which gains are achieved by the unemployed and the underemployed, whether skilled or unskilled.
