Abstract:This literature review has been prepared to synthesize and assess previous large-scale evaluations of telecommuting. First, a conceptual framework is proposed to organize inputs and outputs of a macro-scale telecommuting benefit-cost analysis. Then, four federal and regional reports are examined in terms of methodology, assumptions, economic approach, and major findings. This review identifies common inputs and discusses the critical assumptions that routinely affect the results. Finally, the economic approaches and major findings are presented and compared.
