Our @voxeu column on forthcoming AER paper

"Forced Migration and Human Capital:
Evidence from Post-WWII Population Transfers"

with I.Grosfeld, P.Grosjean, N.Voigtländer, @ezhuravskaya

@MonashBusiness @cage_warwick
@voxeu @ezhuravskaya @MonashBusiness @cage_warwick At the end of WWII, the Polish borders were redrawn, resulting in large-scale forced migration. Poles from Kresy had to move westwards, mostly into formerly German Western Territories (WT), but also to Central Poland. Image
@voxeu @ezhuravskaya @MonashBusiness @cage_warwick The expellees from Kresy were forced to leave behind most of their family possessions and were only allowed to take a small share of their belongings to their new homes. Image
@voxeu @ezhuravskaya @MonashBusiness @cage_warwick We test the "uprootedness hypothesis": forced migration caused a shift in preferences toward investment in human as opposed to physical capital.
@voxeu @ezhuravskaya @MonashBusiness @cage_warwick Before WWII, Polish inhabitants of Kresy were, if anything, less educated than compatriots living elsewhere. This pattern is reversed already in the first generation of children educated after the war, and it persists up to this date (see Figure 3). Image

31 October. Reformation Day.

How did Martin Luther, a little-known professor at a provincial university (founded in 1502), manage to convince large parts of Germany (and Europe) to turn away from the Catholic Church? 🧵(1/N)
(2/N) In Becker/Hsiao/Pfaff/Rubin, we look at Luther's
a. correspondence
b. travels
c. his students at Wittenberg
>before< 1522 when the first city became Protestant, to describe his multiplex network(s).
(3/N) We also look at the trade network in the Holy Roman Empire (HRE).

Luther's message could reach cities across the HRE either through his personal network(s) or by word-of-mouth through the trade network, or by a combination of both.

with Volker Lindenthal, Sharun Mukand, and Fabian Waldinger

A short summary (1/N)

(2/N) Academics of Jewish origin in Weimar Germany were some of the greatest scientific luminaries of the first half of the 20th century.

For example, Nobel Laureates such as Albert Einstein, Erwin Schrödinger, and Max Born shaped modern physics.
(3/N) The National Socialist Party (NSDAP) seized power on January 30, 1933.

On April 7, 1933, the Nazi government started to dismiss academics of Jewish descent from their positions.

The University of Berlin at the time:

Great initiative. I am First-Gen; attended same high school as @PMoserEcon in the deep countryside; my dad left school at age 14, my mum at age 16; dad worked for German rail; mother housewife; ended up at @UniBonn by accident because grandmother lived there (--> free housing).
Started studying maths and physics to become a teacher, following dad's advice: "become a teacher; public sector; safe job".
Met Mathias Hoffmann (@UZH_en) in maths lectures; his passion for Economics made me attend Econ lectures and that's how I ended up studying Economics.
Most important academic in my life was Reinhard Selten @NobelPrize @UniBonn. Amazing person. Humble. Wise. During UG studies wanted to do exchange year abroad, either @UCBerkeley or @ENSAEparis.
Selten: "Swim against the current, go to @ENSAEparis."
