This paper explores the methodology of regime-switching in the analysis of the income
inequality-economic growth relationship. The underlying idea is that when some income
determinant passes a certain threshold introduces a new relationship between inequality and
income and/or income determinants. There are three implications of the estimated models.
First, inequality decreases with economic growth when government consumption as share of
GDP is ?low?. Second, in a ?low? inflation environment government consumption increases
inequality. Third, in countries with ?strict? rule of law openness to international trade and
government consumption are associated with lower inequality, while financial development
implies higher inequality.
