Constitutional loyalty, the importance ascribed to complying with constitutional rules, is difficult to measure across countries due to differences in context, history, and culture. We overcome this challenge by exploiting the COVID-19 pandemic as an ideal setting in which societies around the...

Since the time of the Protestant reformation, Western societies typically consider themselves not to be governed by divine law but based on a social contract. While all rules governing a society are part of this social contract, a country's written constitution is a central and possibly the most...

This article introduces a novel database that measures governments’ compliance with national constitutions. It combines information on de jure constitutional rules with data on their de facto implementation. The individual compliance indicators can be grouped into four categories that we...

Based on data from the EU Justice Scoreboard, we identify a puzzle: National levels of judicial independence (as perceived by the citizens of EU member states) are negatively associated with the presence of formal legislation usually considered as conducive to judicial independence. We try to...

Measurement of both federalism and decentralization has been contentious. We introduce three new indicators reflecting important aspects of both federalism and decentralization. The three new indicators are the result of principal component analysis. When we try to identify their main...

In many modern nation states, both rich and poor, traditional law to this day plays an important role. Given the almost universal prevalence of traditional law, it is surprising how little we know about it. This is the first study that tries to take stock of traditional law from a cross-country...
