From the public discourse, it seems clear that we are living in an age of rising inequality. However, common measures of income and consumption inequality disguise a more nuanced pattern of inequality change across the world. This column argues that inequality within countries has not been rising everywhere and that inequality between countries has decreased. At the same time, technological progress is increasingly displacing basic labour in favour of skilled labour and capital, across borders, and widening the wage gap. The overall effect is unclear. National policies to mitigate inequality are needed but, in the absence of international cooperation, are constrained by cross-border spillovers.

There is mounting evidence that income inequality and disparities in wealth have been rising in advanced economies in the recent decades. Using data on advanced and emerging economies, this column investigates the link between an economy's financial structure – that is, the mix of bank-provided versus market-provided funds – and income inequality. Results show that the relationship is not monotonic. More finance reduces income inequality up to a point, but beyond that point inequality rises, especially if finance is expanded via market-based financing.

Since the turn of the century, income inequality has risen to be among the most prominent policy issues of our time. This column looks at inequality trends in recent decades. While relative global inequality has fallen, insufficient economic convergence, together with substantial growth in per capita incomes, has resulted in increased absolute inequality since the mid-1970s. The inclusivity aspect of growth is now more imperative than ever.
