“…While economic theory is based on utility‐maximizing behaviour, empirical economics has typically relied on revealed preferences to test the validity of competing theories. The strong appeal of life satisfaction data is that it can provide a direct proxy for utility, and recent studies have used this to establish, for example, the trade‐off between unemployment and inflation (Di Tella, MacCulloch, and Oswald 2001), the degree to which unemployment might be involuntary in nature (e.g., Clark and Oswald 1994, Winkelmann and Winkelmann 1998; Clark, Georgellis, and Sanfrey 2001; Kassenboehmer and Haisken‐DeNew 2009), the role of social norms in generating unemployment hysteresis (e.g., Clark 2003; Lalive and Stutzer 2004), the level of inequality‐aversion across the population (Schwarze and Härpfer 2007), and monetary equivalents for different types of health conditions (Ferrer‐i‐Carbonel and van Praag 2002; Frijters, Haisken‐DeNew, and Shields 2004a, b). There are also recent studies that have calculated the costs of terrorism, drought, and commuting using life satisfaction data (Carroll, Frijters, and Shields 2009; Frey, Luechinger, and Stutzer 2007; Stutzer and Frey 2008).…”
