We present a new aggregation method - called SVM algorithm - and use this technique to produce novel measures of democracy (186 countries, 1960-2014). The method takes its name from a machine learning technique for pattern recognition and has three notable features: it makes functional...

We examine how structural reforms relate to income inequality. We employ many indicators of structural reforms and use data for market and net income inequality. The dataset includes up to 135 countries since 1960. The results do not suggest that market-oriented structural reforms were...

We examine how fiscal rules influence economic growth. The results show that constitutional fiscal rules promoted growth from the Industrial Revolution until World War II (1789-1950) and also increased modern economic growth (1985-2015). To address selection on unobservables, we conduct a...

We provide evidence that political instability deteriorates economic growth. We establish this result based on panel difference-in-differences strategies and dynamic panel data models using a large sample of 180 countries, a novel geocoded dataset for 2,660 regions, and micro data for about...

How do global political shocks influence individuals’ expectations about economic outcomes? We run a unique survey on inflation expectations among 145 tenured economics professors in Germany and exploit the 2022 Russian invasion in Ukraine as a natural experiment to identify the effect of a...

Import regulations are globally the most prevalent form of intervention in international trade. The regulations should, under rules of the WTO, protect consumers and the environment but can be used to protect producers. We investigate the ambiguity of intent. We set out a model that when applied...
