We present a new data set we built based on Swiss rich lists going back to 1989. We show, among other things, that 60% of the super-rich are heirs-a fraction twice as large as in the US-and that wealth mobility at the very top has declined significantly. We find that top 0.01% wealth shares are...

We study out-group biases in attitudes toward refugees, and the effect of European Union (EU) immigration policies on these views, using an online survey experiment including 4,087 Italian participants.
