The Unemployment Insurance programme in the US was significantly expanded during between 2008 and 2014. This column examines the effect of unemployment insurance duration on aggregate employment during the Great Recession using state-level expansions and contractions in insurance generosity. It finds a positive but not statistically significant employment impact of expanding the insurance. This suggests that the substantial insurance value of the extensions during the Great Recession was not offset in any meaningful way by any costs from weaker job growth.

While cases of state failure have risen in the last decade, most notably in the Middle East and sub-Saharan Africa, they are not a new phenomenon. Historical evidence from the early modern period, and even the Bronze Age, shows that the majority of formed states have failed rather than thrived. This column introduces the ‘paradox of civilisation’ to characterise the obstacles settlements face in establishing civilisations. The paradox defines the success of a civilisation as a trade-off between the ability to produce economic surplus and to protect it. It is therefore important to correctly balance military and economic support when providing aid.

History offers many examples of the recurring tensions between science and organized religion, but as part of the paper’s motivating evidence we also uncover a new fact: in both international and cross-state U.S. data, there is a significant and robust negative relationship between religiosity and patents per capita. Three long-term outcomes emerge. First, a "Secularization" or "Western-European" regime with declining religiosity, unimpeded science, a passive Church and high levels of taxes and transfers. Second, a "Theocratic" regime with knowledge stagnation, extreme religiosity with no modernization effort, and high public spending on religious public goods. In-between is a third, "American" regime that generally (not always) combines scientific progress and stable religiosity within a range where religious institutions engage in doctrinal adaptation.
