Although benefit-cost analysis (BCA) can be traced back to European thinkers, its first practical applications were in the United States. Recent years have witnessed a growing demand for economic appraisals of policies in different sectors in Europe, but the implementation rate is still low compared to that in the United States. This article introduces a symposium that includes four articles that present current examples of how BCA is being applied in different sectors and in different institutional settings in Europe. They deal with environmental valuation in the United Kingdom, economic analysis for investment in Sweden's transport sector, economic versus financial returns in European Union investment project appraisal, and BCA in EU chemicals legislation. The goal is to stimulate continuing discussion on the implementation of BCA, not only in Europe but also worldwide.
