The effectiveness of NATO conditionality for institutional reforms is highly controversial. Some papers argue that any effect this conditionality might have had may be due to endogeneity effects, i.e. NATO may have picked the winners. We argue that this is not the case. First, NATO-Mazedonia...

Russia and China are assumed to challenge democratization and to promote autocracy. In a first step, we analyze Central Asia as the most-likely case, considering both Russia and China as relevant external actors. We develop a concept for our analysis based on the different strategies of Russia...

Openness to foreign investments is associated with risks. To mitigate these risks, many high-income countries have strengthened the control of foreign investments over the last decade in an increasing number of sectors considered critical. Investment screening distorts the market for...

How do exporting firms react to sanctions? Specifically, which firms are willing - or capable - to serve the market of a sanctioned country? We investigate this question for four sanctions episodes drawing on recent econometric advances in bias-corrected dynamic high-dimensional fixed effects...
