Planet Money Summer School Returns With a Global Economics Tour

NPR's Planet Money Summer School returned in 2026 with a world tour built around a practical question: which economic ideas used in other countries might be worth borrowing, and which should serve as warnings?

The free audio course revisits reporting from more than 15 years of Planet Money and pairs those stories with new conversations with economists. Episodes were scheduled to arrive each Wednesday through Labor Day in the Planet Money podcast feed.

Rather than organising the season around a conventional economics textbook, the programme uses specific places and policies to explain markets, central banking, natural resources, industrial development and financial inclusion.

An NPR report carried by KPBS said the season would travel through examples from Australia, New Zealand, Norway, China and other economies. Each stop connects a local policy or institution with a larger economic principle.

Water markets and inflation targeting

The opening material turns to Australia, where markets have been used to allocate scarce water. The system is designed to move a limited resource toward uses that generate greater economic value, especially during drought.

That approach also creates controversy. Allowing water rights to be traded can bring flexibility and make scarcity visible through prices, but it can invite speculation and raise questions about whether essential resources should be treated like ordinary financial assets.

The case gives listeners a way to examine both the strengths and limits of markets. Prices can coordinate decisions among many users, yet market design determines who can participate, how environmental needs are protected and whether smaller farmers can compete with wealthier buyers.

New Zealand provides a different lesson through the history of inflation targeting. The series explores the work of an economist who was also a jazz musician and helped develop an approach that later influenced central banks around the world.

Inflation targeting gives a central bank a stated objective for price stability and a framework for communicating decisions. Its spread illustrates how an idea developed in one country can become part of global policy practice, although every central bank must adapt the framework to its own economy.

Norway, China and the resource question

Later episodes were set to examine how Norway managed the wealth generated by oil and gas. Resource-rich countries can suffer from corruption, unstable public spending, an overvalued currency and neglect of other industries, a pattern often called the resource curse or paradox of plenty.

Norway's use of fiscal rules and a sovereign wealth fund offers a prominent alternative. Saving and investing a large share of resource revenue can spread benefits across generations and reduce the pressure to spend everything during a boom.

The lesson is not that Norway's institutions can be copied without change. Political trust, administrative capacity and existing income levels affect whether a similar model can work elsewhere. The example instead provides a basis for asking how governments can convert temporary natural wealth into lasting public value.

China offers another contrast. Planet Money said the season would examine an economy shaped by engineering ambition and extensive building, including the gains and risks created by large-scale investment.

Infrastructure can raise productivity and transform regions, but overbuilding can leave debt, unused property and projects whose social value does not justify their cost. China's experience allows the programme to explore how state planning and market incentives interact.

Ideas submitted by listeners

The series also invited the audience to contribute policies encountered while living or travelling abroad. One listener described Taiwan's comparatively simple tax-filing process, including government-provided software that allowed a return to be completed quickly.

Another highlighted rotating savings and credit associations, often known as ROSCAs. These informal groups operate across parts of Africa, Latin America and Asia. Members contribute regularly to a common pool, which is distributed to one participant at a time.

Such arrangements can appear inefficient when compared with an individual bank account. In practice, they can provide commitment, trust and access to finance where formal banking is expensive or unavailable. They also illustrate that economic institutions depend on social relationships as well as contracts and prices.

Economics through reported stories

Planet Money has long used narrative reporting to explain concepts that can otherwise feel abstract. The Summer School format adds a course structure without requiring tuition, exams for credit or prior study.

The 2026 world-tour theme makes comparison the central method. A water market in Australia, an inflation framework in New Zealand or a savings group in West Africa cannot be judged only by asking whether it is unfamiliar. Each must be assessed by the problem it addresses, the institutions supporting it and the trade-offs it creates.

The season does not promise one universal answer to economic problems. Its value lies in showing that countries often face similar challenges but develop different tools in response.

By the end of the course, listeners are meant to have a collection of ideas to debate rather than a single model to adopt. That is a useful economic lesson in itself: policies travel, but context determines whether they succeed after reaching a new destination.
