This article starts with two empirical observations from Organisation for Economic Co-operation and Development countries about longer constitutions: (1) they are more rigid (that is, more difficult to amend) and (2) they are in practice more frequently amended. The study presents models of the frequently adopted rules for constitutional revision (for example, qualified majorities in one or two chambers, referendums) and demonstrates that, if longer constitutions are more frequently revised, it is because they must impose actual harm on overwhelming majorities. In trying to explain this finding, the article demonstrates that longer constitutions tend to contain more substantive restrictions. Countries with longer constitutions also tend to have lower levels of GDP per capita and higher corruption. Finally, the negative effect of constitutional length on GDP per capita is shown to persist even if corruption is controlled for.

In response to growing economic and political interdependence at the international level, contemporary theories of justice have debated whether the demands of distributive justice extend beyond the nation-state. This article addresses the reverse question: whether and how the demands of justice arise below the state, at the level of civil society associations. This question becomes pressing in light of the increasing fragmentation of national governance, and the resulting institutional interdependence between political institutions and private associations. The article argues that the extent to which these associations are directly bound by egalitarian principles depends on a complex set of factors, including their structure and size, their role in the social provision of important goods, and their institutional relation with political institutions.

In international disputes, forgone settlement offers are frequently lamented, but their impact on the dynamics of ongoing negotiations is largely overlooked. In the psychological literature, however, the consequences of missing an advantageous action opportunity have been studied extensively in the context of the inaction inertia phenomenon. According to this literature, forgoing attractive action opportunities renders decision makers susceptible to regret and increases the likelihood that subsequent opportunities will also be missed. This article explores the explanatory potential of the inaction inertia effect in the context of international negotiations. Findings based on laboratory experiments and analysis of the negotiations between Israel and Hamas over the release of the Israeli soldier Gilad Shalit strongly suggest that the concept of inaction inertia can enrich the understanding of failures and deadlocks in international negotiations. The article defines the conditions that are instrumental in identifying inertia-induced deadlocks and discusses factors that encourage the termination of inaction inertia and promote dispute settlement.

The unusually stable Earth system of the Holocene epoch of the past 10,000 years, in which human civilization arose, is yielding to a more dynamic and unstable Anthropocene epoch driven by human practices. The consequences for key institutions, such as states, markets and global governance, are profound. Path dependency in institutions complicit in destabilizing the Earth system constrains response to this emerging epoch. Institutional analysis highlights reflexivity as the antidote to problematic path dependency. A more ecological discourse stresses resilience, foresight and state shifts in the Earth system. Ecosystemic reflexivity can be located as the first virtue of political institutions in the Anthropocene. Undermining all normative institutional models, this analysis enables re-thinking of political institutions in dynamic social-ecological terms.

Voluntary compliance is an important aspect of strong tax regimes, but there is limited understanding of how social norms favoring compliance emerge. Using novel data from urban Nigeria, where tax enforcement is weak, this article shows that individuals with a positive experience of state services delivery are more likely to express belief in an unconditioned citizen obligation to pay tax. In addition to support for this fiscal exchange mechanism, social context is consequential. Where individuals have access to community-provided goods, which may substitute for effective state services provision, they are less likely to adopt pro-compliance norms. Finally, the article shows that norm adoption increases tax payment. These findings have broad implications for literatures on state formation, taxation and public goods provision.
