From costs to culture: what’s behind falling fertility in rich countries?

Fertility rates have fallen rapidly in the UK and other high-income countries in recent years. Education, economic uncertainty and changing gender roles are among the factors that have played a part. Keeping the combination of causes in mind is essential for designing effective policy responses.

AI pessimism in rich countries

Richer countries are consistently more pessimistic about AI’s impact.

In polling conducted by Ipsos for Stanford’s Artificial Intelligence Index 2025, every country with a GDP per capita below $36,000 – around the level of Malaysia or Chile, after adjusting for differences in local prices – expects AI to deliver more benefits than drawbacks. In contrast, richer countries, including the United States and European economies such as Switzerland, the Netherlands and Norway, are the most cautious. Singapore stands out as an exception: both wealthy and strongly optimistic about AI.

Trust and technology: what went wrong with the Post Office?

The Post Office scandal brought into sharp focus the risks associated with placing blind faith in technology. To learn from this troubling episode and start rebuilding public trust, policy-makers must challenge the idea of the infallibility of machines within the legal system.

UK land and property: what’s happening with freehold and leasehold reform?

For decades, landowners have fought to maintain the legal structure governing ownership and occupancy of multi-tenanted residential blocks. But growing awareness of the legal jeopardy of being a long-term flat occupier – plus the economic constraints of land law – have prompted demands for reform.

Will digital failures undermine trust in the justice system?

Global defence spending: What next for European military procurement?

With its fragmented production process, European defence procurement is inefficient and uncompetitive in comparison to the United States. A new approach, prioritising cross-country collaborations, could improve things, but would not be without its own challenges.

Have the UK’s northern cities really experienced a productivity miracle?

While official data points to a ‘productivity miracle’ in several large northern cities since 2019, a closer look suggests otherwise. This serves as a reminder to sense-check any data before using it, regardless of the source.

How might policy-makers improve Moldova’s economic prospects?

Compared with other former Soviet territories, Moldova is an outlier in terms of its poor economic performance. Political instability, together with a heavy dependence on remittances as well as international loans, means policy-makers must work carefully to improve living standards through strategic reforms and closer alignment with Europe.
