Economics in Detention is a University of Maryland Extension program that teaches inmates essential principles of economics as a foundation to a spectrum of decision making. Also, the program includes an emphasis on starting a small business after incarceration. The idea of this program emanates from an invitation by the Baltimore City Detention Center to design a program that would engage and challenge inmates to learn and apply practical knowledge beyond General Education Development (GEDR). The program incorporates Microsoft Excel with the teaching of basic concepts in economics for inmates to acquire small business decision-making techniques. Evaluation results from the program indicate that business-minded inmates consider the program unique, practicable, and inspirational.
