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...

Constitutional democracy is in decline and many would-be autocrats try to elude constitutional constraints or even to exploit constitutions in their favor. We make a number of proposals for designing constitutions that are more resilient against such attempts. A first look at the empirical...

No other religion's role in politics is as controversial as that of Islam – at least in Western societies. It has been claimed that Muslims are more likely than others to voice opinions that conflict with core elements of a free society, such as capitalism, constitutional democracy, and the...

Abstract Over the last decades, more and more countries have integrated environmental protection into their constitution. In this article, we argue that a simple economic model can explain why some countries have adopted the legal innovation of constitutional environmental protection, while...

This paper does three things. First, based on a limited number of theoretically established dimensions, it proposes a new de facto indicator for the rule of law. It is the first such indicator to take the quality of legal norms explicitly into account. Second, using this indicator we shed new...

Understanding corruption is at the heart of treating the dysfunctionality of many countries' public sectors. Yet, most corruption research suffers from one common problem: There is no "objective" measure of public-sector corruption for a cross-section of countries. Most studies on the...

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...
