Financial deregulation in the US has been shown to be associated with rising income inequality over the past four decades. This column looks at the income effects of financial deregulation in the UK and Japan during the 1980s and 1990s. As in the US, deregulation substantially increased the shares of income going to the very top of the distribution. These findings highlight the importance of financial markets in the evolution of income inequality in society.
