Using panel cointegration methods to understand rising top income shares

Tim Neal

Research output: Contribution to journalMeeting abstract


Purpose: Rising top income shares in developed countries have recently generated a great deal of political and economic discussion. While many theories have been proposed to explain this increase, there has been little robust econometric testing of those explanations. This paper seeks to understand top income shares using econometric modelling. Findings: Our analysis finds that economic openness, the size and ideology of Government, the development of financial markets, top marginal tax rates, and the strength of unions are all important determinants of top income shares. By contrast, there is no evidence to support the notion that skill-biased technological progress has led to rising top income shares. Practical and Social implications: These results offer a comprehensive explanation of why top income shares have been rising in a number of developed economies in the last three decades. The implications on economic and social policy extend towards potential avenues for reform in addressing/counteracting the rise, depending on the degree to which policymakers and voters believe that this rise has adverse effects on the economy and wellbeing.
