Just as many of the most important foundational results in BCA emerged from policy applications, the policy case studies using BCA also provide valuable insights. A common concern pertains to which group’s benefits are being measured. Are we assessing the private benefits to the decision maker or the social benefits?  The article by Del Rossi and Hersch (2016) examines these benefit-related consequences for double majors, examining which double majors provide a financial payoff to the individual, and which have broader societal dividends. BCA studies often use the results of surveys, but if there is self-selection of participants the estimated effects may be biased. Policies may also have different effects on different households. The article by Kniesner and Rustamov (2018) analyzes an energy efficient audit program, taking these important econometric concerns into account. After adjusting for self-selection influences, they find that the impact of the program varies markedly across the population based on their level of electricity usage. The article by Karoly (2012) develops a set of standards to be applied when undertaking a BCA of an early childhood program. Many of the concerns, such as which outcomes should be valued, arise in other policy contexts as well. Benefit assessments often focus on situations in which reliable market data are not available. Cohen (2015) provides new survey evidence on the willingness to pay to avoid white-collar crime, which he compares to the value of reducing household burglary. The final article by Fraas and Lutter (2016) assesses the efficacy of federally mandated information disclosures. They examine a series of case studies of such federal mandates undertaken from 2008 to 2013 and provide lessons for future policy reforms.
