Is It the Government's Responsibility to Reduce Income Inequality? An Age-Period-Cohort Analysis of Public Opinion toward Redistributive Policy in the United States, 1978 to 2016. Issue 3 (4th May 2018) - Lin, Ya-Feng
Abstract: This study examines age, period, and cohort (APC) effects on changing opinions among the American public toward the federal government's responsibility for income redistribution. More specifically, we use the hierarchical age–period–cohort (HAPC) model to analyze time periods and birth cohorts as contextual variables and age as an individual-level variable to address the identification problem inherent in APC analysis. Our results show that while cohort effects on public opinion toward redistributive policy exist, such effects are explained by individual-level compositional differences among cohorts, and while period effects are evident, particular trends in that regard are difficult to discern. What our results make abundantly clear, however, is the significant impact of age on opinions toward redistributive policy. As people age, they become significantly less supportive of federal redistribution policies, a relationship that is robust in the presence of cohort and period effects as well as a full range of controls. In the context of a rapidly aging population, the implication is that more conservative policy preferences linked to older age provide little reason to believe that mass support for government redistribution is in the offing.
