Marketplace doesn’t always cover the goings-on of the Holy See. But when he highlights the need to combat poverty, it seems like a pretty good time to do so. In his first teaching last week, Pope Leo XIV called into question some basic tenets of mainstream economics and focused on the gap between the rich and the poor. Today, we discuss. Also on the show: the research of Nobel laureate economists and Trump's attempts to calm markets over China trade.

This morning, the winners of the Nobel Prize in economics — three professors whose work centers on technological innovation and what helps economies grow — were announced. Marketplace senior economics contributor Chris Farrell joins the program to discuss their research. Plus, the USDA notified states that they need to make big changes to SNAP eligibility, work requirements, and who’s covering costs. But advocates worry about the tight deadline for changes.

From the BBC World Service: Trade tensions are flaring as Beijing responds to President Donald Trump’s threats to tack an additional 100% tariff on Chinese goods. China has warned of "corresponding measures," though new data shows that China’s exports are booming. So does China still need the U.S.? Then, Nigeria produces nearly 40% of the world's shea nuts, which sustains a multibillion-dollar trade in cosmetics, food, and medicine. But new trade restrictions are being felt throughout the shea nut supply chain.

Federal programs and funding play an important role in Indian Country, because of the government’s trust responsibility to provide or fund services to tribal nations in exchange for ceded land that now comprises the United States. That relationship also means that shutdowns hit tribal nations particularly hard. We'll learn what that means for services like health care and food distribution programs. Then, a lifelong Las Vegas resident reflects on the city's economic slowdown.

The travel and tourism industry contributes $2.9 trillion to the U.S. economy — more than the size of the automotive industry. But can travel and tourism thrive at a time when the United States is working to overhaul border and trade policy? We'll hear how some Trump administration policies are affecting business on the ground in Las Vegas, Nevada. Plus, the U.S. has finalized its $20 billion bailout of Argentina's currency.

From the BBC World Service: The European Union's new Entry/Exit System will be rolled out on Sunday, but there have been warnings it could cause delays at passport control. The change affects all countries in the Schengen area. Then, India’s southern state of Karnataka — home to Bengaluru, the country’s Silicon Valley — has approved one day of paid menstrual leave per month. Also: the NBA in China and AI at Versailles.

Starting Friday, federal workers will be getting their first paychecks for smaller-than-usual amounts as a result of the government shutdown. That’s likely to especially sting federal employees who still have to show up to work, including TSA agents and air traffic controllers. They've helped up the pressure to end shutdowns before. Could they do it again? Plus, we'll unpack how C-suite execs are currently feeling about tariffs and artificial intelligence.

Las Vegas is arguably the discretionary spending capital of the country, if not the entire world. This makes it a good barometer for understanding the current economy — not just of one city or state, but the entire nation. And right now, Vegas is grappling with declining tourism and a high unemployment rate. We'll visit Sin City to learn more about the slump. Plus, why is China stepping up controls on rare earth metal exports?
