Open oceans are vital for the transport of a large share of world trade. But they are also frequently at the centre of geopolitical tensions between nation states. This column estimates the economic costs of impeded shipping access in South East Asia. The results of the study suggest that restrictions to shipping due to military sanctions could have large negative effects on economic welfare for countries all over the world, including oil exporters such as the United Arab Emirates and Saudi Arabia.

The US military community has highlighted the potential security threat posed by foreign venture investments in Silicon Valley, particularly from Chinese stakeholders. This column presents a theoretical and empirical analysis of the relationship between venture capital and national security, focusing on the ability of overseas firms to gain a domestic technological advantage through investing in the US tech sector. The growing importance of this the technology sector, as well as the national security issues at stake, mean that understanding the correlations is a vital avenue of future research.

Individuals, citizens and firms have become increasingly dependent on data-driven services such as artificial intelligence and apps, and the same is true of defence and national security officials. This column argues that the US failure to adequately govern how firms use and monetise data affects national security in many ways. It also examines specific examples of the misuse of data and assesses the responses by the US and the EU.

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.

Economic logic suggests that politicians are overprotected and therefore too isolated from citizens; the social cost of a political assassination is much lower than its private cost to the politicians, and the private cost of protection is lower than the social cost. Moreover, authoritarian rulers are more overprotected and isolated than democratic politicians since assassinating them has more impact on policy.
