It's called the "lipstick effect." Consumers sometimes splurge on small luxuries — like cosmetics, accessories, and more — as a sort of rebellion against a bleak economic backdrop. And these indulgent purchases are expected to be big in the year ahead. Also: the toll tariffs have taken on the economy as Trump threatens more over Greenland and the impact of a growing number of millionaires in the United Arab Emirates.

President Donald Trump has made it very clear that he wants to purchase Greenland, although he hasn't ruled out the use of military force. Now, he's threatening to increase tariffs on eight European countries unless they agree to let the U.S. purchase the Danish territory, and the European Union is considering retaliation with its own tariffs on U.S. products. Also on the show: Europe is emerging as a major new destination for low-cost items from China.

From the BBC World Service: New data shows that China's economy grew by 5% last year. While positive, it’s not anywhere near the stellar growth figures China has had over years past, and the economy faces a weak housing market, a falling population, and ongoing trade tensions with the U.S. Plus, we examine what's driving the wealthy to the United Arab Emirates and how a boom in luxury real estate is changing Dubai.

In an industry known for pushing the bounds of human innovation, tech elites are now trying to push the bounds of their own bodies. The hot new biohacking trend is injectable peptides — similar to the ones found in GLP-1 medications like Ozempic. But these are not approved by the Food and Drug Administration.

These gray-market peptides, largely from Chinese manufacturers, are being used by tech workers and founders. Not just to lose weight, but to optimize their health and performance in all manner of ways. “Marketplace Tech” host Meghan McCarty Carino speaks with independent journalist Jasmine Sun, who recently wrote about this for the New York Times.
