Why are you right-wing, left-wing, or in the middle? You probably believe that you made a genuine, calm, and ethical choice. But what were the deep causal forces upon those political preferences?
The scientific roots of people’s political views are poorly understood. One possibility (View 1) is that individuals’ attitudes to politics and redistribution are motivated by deeply moral views. Another possibility (View 2) – and this is perhaps some economists’ presumption -- is that voting choices are made out of self-interest and then come to be embroidered in the mind with a form of moral rhetoric. Testing between these two alternative theories is important intellectually. It is also inherently difficult. That is because so many of our attitudes as humans could stem from early in life and are close to being, in the eyes of the researcher, a ‘person fixed-effect’.
In most data sets, rich people typically lean right. The fact that high income and right-wing views are positively correlated in a cross-section has been repeatedly documented in quantitative social science (recently, for example, by Brooks and Brady 1999 and Gelman et al. 2007 in US data, and by Evans and Tilley 2012 in British data). An analogous result is reported, using quite different kinds of methods, in Karabarbounis (2011). Economists such as Di Tella and MacCulloch (2005) have also studied political views and their implications, and other influences have been examined using causal evidence on political views (such as in Oswald and Powdthavee 2010 and Erikson and Stoker 2011).<
