Can one single political leader influence macroeconomic expectations on a global scale? We design a large-scale survey experiment among influential economic experts working in more than 100 countries and use the 2020 US presidential election as a quasi-natural experiment to identify the effect...

We examine the deep roots of preferences for vaccination against COVID-19, moving beyond proximate factors which can only account for part of the observable heterogeneity in the willingness to get vaccinated. Our model on experience-based learning predicts that exposure to past disruptive crises...

Most industrialized countries today are facing historical demographic changes, paring increasing retirement with a declining labor force. We study the consequences of an increasing pensioner-worker ratio in a macroeconomic framework, which suggests a negative effect on total factor productivity....

Inequality between ethnic groups has been shown to be negatively related to GDP, but research on its effect on contemporary economic growth is limited by the availability of comparable data. We compile a novel and comprehensive dataset of harmonized Gini indices on ethnic inequality for...

We present a novel approach for measuring democracy based on Support Vector Machines, a mathematical algorithm for pattern recognition. The Support Vector Machines Democracy Index (SVMDI) is continuously on the 0-1-interval and enables a very detailed measurement of democracy for 188 countries...

We compile data for 186 countries (1919 - 2016) and apply different aggregation methods to create new democracy indices. We observe that most of the available aggregation techniques produce indices that are often too favorable for autocratic regimes and too unfavorable for democratic regimes....

Scholars have been active in investigating causes and consequences of austerity policies. We examine how economists use the term “austerity” in scientific studies and measure austerity in empirical analyses. The sample includes around 3,500 journal articles published in the top 400 journals...

We show that culture and diversity strongly influence welfare systems around the globe. To disentangle culture from institutions, we employ regional instruments as well as data on the prevalence of the pathogen Toxoplasma Gondii, linguistic differences, and the frequency of blood types. The...

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...

The nexus between corruption and economic growth has been examined for a long time. Many empirical studies measured corruption by the reversed Transparency International’s Perception of Corruption Index (CPI) and ignored that the CPI was not comparable over time. The CPI is comparable over...
