On today’s episode, we have three big economic ideas for your consideration – ideas that could potentially improve the economy and make us more efficient.

First, what if we ban left turns on roads? Then, what if we gave every new baby … a trust fund? And lastly, what if we completely got rid of U.S. congressional districts?

That’s all on today’s episode.

Planetary scientists and OSIRIS-REx co-investigators at NASA’s Johnson Space Center walk us through the processes and emotions of working in the lab with asteroid Bennu’s precious samples. HWHAP Episode 319.

On today’s show, we look at two indicators of the economic disruptions of the war in Gaza and try to trace how far they will reach.

We start in the Red Sea, a crucial link in the global supply chain connecting to the Suez Canal, with around 15% of the world’s shipping passing through it. This includes oil tankers and massive container ships transporting everything from microchips to furniture. With Houthi rebels attacking container ships in solidarity with Palestinians in Gaza, shipping lines are re-routing, adding time and cost to delivery. We look at how ocean shipping is a web more than a chain of links, and try to see which parts of the web can take up more strain as the Red Sea and the Suez Canal become too dangerous to pass.

Then, we’ll consider what escalation could mean for the region’s most important export: oil. Five steps of escalation each mean a ratcheting up of costs that knock on to other industries, like food. Some prices are likely to rise faster than others, though.

When you think of a potato, one state probably comes to mind: Idaho. But for much of American history, Maine was home to the nation’s largest potato crop.

That status had changed by the 1970s, with the West growing more and more of the nation’s potatoes. But Maine still had one distinct advantage: A privileged position in the commodities market. The New York Mercantile Exchange, one of the largest such marketplaces in the country, exclusively dealt in Maine potatoes. And two deep-pocketed Western potato kingpins weren’t happy about it.

So the Westerners waged what’s now called the Maine Potato War of 1976. Their battlefield was the futures market: A special type of marketplace, made up of hordes of screaming traders, where potatoes can be bought and sold before they’re even planted.

The Westerners did something so bold – and so unexpected – that it brought not only the potato market, but the entire New York commodities exchange, to its knees.

Today on the show, how a war waged through futures contracts influenced the kind of potatoes we eat.

This episode was hosted by Dylan Sloan and Nick Fountain. This episode was produced by Sam Yellowhorse Kesler with help from Emma Peaslee. It was edited by Molly Messick, engineered by Valentina Rodríguez Sánchez, and fact checked by Sierra Juarez. Our executive producer is Alex Goldmark.
