“…In part, this may be because the effects of financial constraints on behavior have been examined in several different ways across several different literatures. These literatures include research on resource scarcity (Cannon, Goldsmith, & Roux, 2018;Shah, Mullainathan, & Shafir, 2012), choice restriction (Botti et al, 2008), social comparison (Kraus, Piff, & Keltner, 2009) and environmental uncertainty (Chen & Miller, 2012). To illustrate the diversity of methodologies employed, some studies experimentally induce financial constraints, whereas others measure chronic constraints; some studies operationalize financial constraints as absolute income, whereas others focus on relative standing; some focus on financial constraints in childhood, whereas others focus only on adulthood.…”
