The Condorcet Jury Theorem is derived from the implicit assumption that jury members only commit one type of error. If the probability of this error is smaller than 0.5, then group decisions are better than those of individual members. In binary decision situations, however, two types of error...

We study changes in the form of government as an example of endogenously determined constitutions. For a sample of 202 countries over the period 1950-2006, we find that most changes are relatively small and roughly equally likely to be either in the direction of more parliamentarian or more...

A country's form of government has important economic and political consequences, but the determinants that lead societies to choose either parliamentary or presidential systems are largely unexplored. This paper studies this choice by analyzing the factors that make countries switch from...

De jure judicial independence (JI) is the single most important predictor of de facto JI. In this paper, we describe under what conditions countries are likely to include JI in their constitutions. We describe and analyze both their original choice in this regard as well as change over time...

This paper studies correlates and determinants of direct democracy institutions (DDIs), such as referendums and initiatives, based on the premise that constitutions themselves are endogenous. Our sample covers as many as 132 countries from 1950 to 2006. We find that the likelihood that a country...

It is often conjectured that non-state dispute resolution blossoms when state courts are not independent or are perceived as low-quality courts. This conjecture implies a substitutive relationship between state and non-state dispute resolution. An alternative hypothesis argues that both the...

This paper analyzes whether nation-state governments can increase their credibility by becoming members of international organizations. Credibility is an important asset because it determines the real interest rate and is expected to have an important impact on investment and growth. It is...

Analysis of the economic effects of constitutional rules has made substantial progress over the last decade. This survey provides an overview of this rapidly growing research area and also discusses a number of methodological issues and identifies underresearched areas. It argues that the next...

This paper is based on the conjecture that institutional details matter and that attempts to estimate the economic effects of federalism by drawing on a simple dummy variable neglect potentially important institutional details. Based on a pricipal component analysis, seven aspects of both...

The economic effects of federalism are unclear: some papers find that federalism has strong positive effects on a number of economically relevant variables, others find negative effects. The results often crucially hinge upon the proxies for federalism used. In this paper, we critically survey...
