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...

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...

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...

Prosecutors are immensely influential in every judicial system, yet very little is known about the impact of their organization. Here we ask two questions: (1) whether crimes committed by public officials are more likely to be prosecuted when prosecutors are independent, and (2) whether this...

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...

While research in constitutional economics has made important progress in recent decades, the factors determining whether a constitution is complied with have only received scant attention. We contribute to that narrow literature by studying how personal traits of political leaders are...

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...

We bring attention to a previously overlooked determinant of de jure-de facto constitutional gaps: a polity's transition to a nation-state. We argue that nation-statehood, predicated on the formation of a strong sense of national identity, lowers the government's incentive to violate...
