ABSTRACT
This chapter explains the theoretically expected differences in work ethic as latent dependent variable by including predictor variables into the full multilevel regression model and comparing the results with those from Ordinary Least Square Regression (OLS-regression). In their OLS-regression, P. Norris and R. Inglehart used an additive index for work ethic as dependent variable. In his book Modernization and Postmodernization, Inglehart embeds his theoretical approach of an intergenerational value change toward postmaterialist value priorities into a broader theoretical approach of social change, whereby two successive phases are distinguished. The OLS-regression model for work ethics presented by Norris and Inglehart includes a society's type of religious culture, a country's Human Development Index (HDI), and its Level of Political Development as macro-level variables and a respondent's age, gender, education, income, and religiosity as micro-level variables. To overcome inconsistencies between the theory and the model, interaction effects between the HDI and cohorts as well as between the HDI and education were also tested.
