“…Examples of work featuring the decomposition of effects into extensive and intensive margins include estimates of the effect of benefit-receiving on food expenditure (Hastings and Washington, 2010), the effect of various variables on intra-and inter-firm trade (Co, 2010), the effect of employer contributions on employee pension savings (Engelhardt and Kumar, 2007) the effect of worker productivity or unionization on working overtime (Sousa-Poza andZiegler, 2003, andTrejo, 1993, respectively), the effect of managers' tax evasion preferences on underreporting corporate income (Joulfaian, 2000), the effect of various regressors on youth unemployment (Caspi et al 1998), and the effect of health knowledge on health outcomes 2 (Kenkel, 1991). The list is neither complete nor representative, but it is suggestive of the widespread use of the decomposition in corner solution applications.…”
