That's the question before the Supreme Court this week. President Donald Trump has been declaring an emergency and then using emergency authority to impose many of these tariffs. Treasury Secretary Scott Bessent is among those who've said they expect to prevail in the high court, but if they don't, there are other ways to apply taxes on goods from other countries. Also: BP shale asset sales and a dark side of the drug rehab industry.

This past weekend, as the shutdown stretches on, funds for SNAP benefits began to dry up. The Treasury Secretary says payments could restart this week, and a federal court said the Trump administration must tap into emergency funds to get this done. Today, we'll check in with the Arkansas Hunger Relief Alliance for a snapshot of food insecurity there. Plus, Trump says he wants to fix Obamacare, and U.S. auto production could be hampered by a looming chip shortage.

From the BBC World Service: Markets in Asia rose in reaction to the outcome of the APEC meetings in South Korea as the U.S. and China stepped back from the brink of a full-fledged trade war. Plus, reports suggest India is looking for new sources to replace the oil it currently buys from Russia. And, we look at Cameroon's mining industry, which is often done by small-scale miners working in risky environments with basic tools.

The government shutdown has now lasted a full month. Now, some business leaders — including the U.S. Chamber of Commerce, the Business Roundtable, the American Bankers Association, and more — have issued a statement urging Congress to reopen the government. They cite estimates that the shutdown will cause $10 billion to $15 billion per week in lost output and economic activity. Plus, how much would you spend to find a job?

The personal consumption expenditures price index, the Federal Reserve's favorite inflation measure, was supposed to be released today. But at day 31 of the government shutdown, it's nowhere to be found. This morning, we'll unpack what exactly we know about rising prices at a time of tariffs. And later, is 9 to 5 looking more like 7 to 7? We'll learn about the rise of the work trend known as "microshifting."

From the BBC World Service: Chinese President Xi Jinping told leaders attending the APEC summit in South Korea of the need to deepen economic cooperation amid global uncertainty. We'll hear the latest on trade agreements between the U.S. and China, as well as other new developments. Then, Jamaica's government issued a catastrophe bond as it begins recovery from Hurricane Melissa. And later, would you spend money on a job search to try to get a leg up?

President Donald Trump and Chinese President Xi Jinping have pulled U.S.-China relations back from the brink. China says both sides will suspend plans to expand export controls — the U.S. on advanced tech and China on rare earths — and Trump will reduce tariffs on China’s exports by 10%. Plus, Meta stocks are down in the dumps, and the Netherlands is experiencing growing pains in the clean energy transition.

If nothing changes before the weekend, most of the 42 million people on food stamps, or SNAP, will not get their November benefits as scheduled. The interruption for people who rely on SNAP to buy food would be significant but could also have broader ripple effects across the economy, as SNAP generates jobs, wages, and taxes. Also: the track record of past New York City rent freezes and the likelihood of future rate cuts this year.

From the BBC World Service: At a long-anticipated meeting, U.S. President Donald Trump met with Chinese President Xi Jinping in South Korea and discussed a possible truce in the trade war. What happens now between the world's two largest economies? Then, thousands of homes and businesses in the Netherlands are waiting to connect to the electricity grid, and thousands more are waiting to inject power back into the system. But the grid is struggling to cope with the transition to green energy.

Researchers figure livestock herds contribute between 12% and 20% of the world's greenhouse gas emissions. That's mostly methane from the digestive process. But a study from UC Davis finds that, when fed seaweed early on, cattle’s microbiome can be altered, reducing the amount of methane emissions. But first, the Federal Reserve is expected to cut interest rates by a quarter of a percentage point — though they have limited data to go off of.
