Across Berlin, Holocaust victims are remembered with stumbling blocks. The memorials always leave a deep impression on me. Do such memorials affect attitudes? In a new paper, we find the blocks have a negative “effect” on the vote-share of the xenophobic AfD party.

Has #Hamas invasion affected public opinion toward the conflict? By pure coincidence, @miguelmaria and I currently have a survey in the field, measuring who Germans blame for conflict in the ME. The attack has significantly shifted opinion: A majority now blames Palestinians.

Are protesters motivated by the size of their own group? In our @apsrjournal we find: as the own protest gets larger, left-wing activists become *more* likely to protest. By contrast, far right activists become *less* likely to protest. So, the right is free-riding! A thread

Is surveillance an effective tool to silence dissidents? I've wondered about this question ever since I saw the movie "lives of others." In a new paper, we use data from Communist Poland and show that surveillance actually backfired and sparked protests.

@miguelmaria The stumbling blocks are a unique memorial. They are decentralized, and thus create a very personal, immediate connection to a victim. One cannot go across Berlin without noticing them. The sheer number creates a constant reminder of the horrors of the Holocaust (see map).

@miguelmaria Berlin is also the birthplace of a more decentralized memorial, the stumbling block. Invented by artist Gunter Deming, the brass plaques are placed in front of the homes of former victims. The plaques include information such as the victims' names, fate and date of death.

@miguelmaria In our paper, we collected the time and location of all nearly 10,000 Berlin stumbling blocks. We then exploit this temporal and geographic variation and correlate it with the AfD’s vote share across seven elections in local precincts (N = 2200).

@miguelmaria Using a variety of modern diff-in-diff estimators, we find a negative connection between stumbling blocks and the AfD’s vote share. Seemingly, the stumbling blocks reduce xenophobic voting. (Of course, this is not a randomized experiment, so update your beliefs accordingly).

@miguelmaria Can decentralized memorials affect political behavior? If so, for which party and how? In our preregistration, we focused on the far-right, xenophobic AfD. The party is explicitly opposed to Holocaust remembrance. Key leaders have called Germany’s memory policies a “guilt cult”.

@miguelmaria But whether memorials “work” in reducing xenophobic voting is unclear. On the one hand, one may expect the memorials to create guilt and shame, and thus lead voters away from the AfD. On the other hand, the memorials do create backlash and are frequently vandalized.

@miguelmaria There is also some tentative evidence that the memorials, indeed, trigger guilt. For instance, blocks informing about survival (vs. death) show no negative correlation. But we want to explore this more (see also the experiment by @melinscribe ).

In a new paper, we show that rent control makes tenants *less* NIMBY. That is, rent-controlled tenants are more open to new construction. Evidence comes from Berlin, which afforded us two neat discontinuities in its recent rent control legislation.

@mgoldenProf @miguelmaria Thank you, Miriam. We don’t have indivual-level data (only voting data), so the guilt mechanism is just a conjecture. But some heterogeneity points into this direction (effects stronger when victims died as opposed to fled). And we’re currently designing an exp to get at it

Third we show that society approves of left-leaning protests (more so than for right-leaning ones). So, again, larger protest turnout gives potential activists an additional incentive to take to the streets.

Why is that? Why, in other words, are left-leaning activists more likely to turn out when the own protest is large. We offer three mechanisms. First, we show that left-leaning respondents are more connected to their movement. So there is a social reason to attend.

What made this project challenging is that surveillance is usually hidden! Luckily, after much searching, we found data on secret police activities in Poland. Whats neat: the data is at the village-level. We were thus able to construct a panel of spy activity between 1948-1989.

Second, respondents *did* react strongly to the size of their own protest. On the political right, activists become *less* likely to protest when when their own group is large. But on the left: activists become *more* likely to protest when when their own group is large.

What do we find? First, turnout in the opposing protest does *not* matter. Neither on the political left nor right does larger turnout in the opposing movement affect potential activists’ protest intentions. So, people look at their own group!

Existing studies give us competing answers to these questions. Perhaps “the more the merrier”, so a bigger protest makes you want to protest, too. Alternatively, if the protest is big your impact is relatively small, so you may stay at home.
