*out now* my meta-analysis on the effect of globalisation on income inequality: the impact of trade globalisation is small, but financial globalisation shows a sizable inequality-increasing effect. Just published in "The World Economy"; thread: /1

For the meta-analysis, I built a new data set consisting of 1254 observations from 123 primary studies on the globalisation-inequality nexus /2

The meta-analysis reveals that the average (precision-weighted) globalisation-inequality effect is positive and robustly different from zero suggesting that globalisation increases income inequality. /3

I conduct a multivariate meta-regression analysis to test for sources of heterogeneity in reported globalization-inequality estimates. Main finding: while the effect of trade globalisation is small, financial globalisation shows a more sizable and significantly stronger impact./4

The cumulative evidence rejects theoretical accounts according to which economic globalisation reduces within-country income inequality in developing countries as the meta-analysis establishes an average inequality-increasing impact in both advanced and developing countries /5

The meta-analysis reveals an average inequality‐increasing impact of globalisation in both advanced and developing countries. Education and technology moderate the impact of globalisation on income inequality. /6

The tests on publication selection bias did not uncover evidence that the econometric estimates reported in the literature are significantly influenced by publication selection bias. /end
