Rising wage inequality in the U.S. and Britain and rising continental European unemployment have led to a popular view in the economics profession that these two phenomena are related to negative relative demand shocks against the unskilled, combined with flexible wages in the Anglo-Saxon...

Rising self-employment rates in U.S. tax data that are absent in survey data have led to speculation that tax records capture a rise in new "gig" work that surveys miss. Drawing on the universe of IRS tax returns, we show that trends in firm-reported payments to "gig" and other contract workers...
