MacKenzie Bezos found a great way to upstage her ex: signing the “Giving Pledge,” which is a promise to give away half her wealth to good causes while living. Jeff Bezos hasn’t signed.

That’s not to say Bezos hasn’t made big charitable giveaways. Business Insider published a list of some that have been publicly disclosed. But for the richest man in the world—at an estimated $114 billion—they seem a bit stingy. Meanwhile, the No. 2 and No. 3 on the billionaires list—Bill Gates and Warren Buffett—have both signed the pledge; in fact, they started it along with Melinda Gates.

Worth noting that Gates’ generosity blossomed after his showdown with government antitrust authorities. Is Bezos waiting for the same? Might be good for business, as well as for the world, if he jumps on this bandwagon sooner rather than later.

Rare Earths

Asia-Pacific rare earths miners have seen their shares soar, following veiled threats from a Chinese official that the minerals could become leverage in the U.S.-China trade war.

Boeing Warning

An Ethiopian Airlines pilot warned senior managers of a need for better training and communication, following the crash of a Lion Air Boeing 737 Max in October.

Huawei Plea

Huawei has filed a motion for a summary judgement to halt the U.S.'s "illegal action" against it.

Worker Ownership

Bernie Sanders is formulating a plan that would force large businesses to put some of their stocks into an employee-controlled fund, so workers would get regular dividends. He also wants corporations to give workers seats on their boards—an idea that's already been proposed by Elizabeth Warren, and that is commonplace in Germany. Washington Post

Digital Currency

Central banks such as that of Sweden may be exploring the possibility of issuing official digital money, but Germany's central bank chief is skeptical.

Tory Business

British Health Secretary Matt Hancock is one of the many people running to succeed Theresa May at the helm of the Conservative Party (and the U.K.,) and he's pitching himself as the pro-business candidate.

If nothing else, the British asterisk sector has a rosy future. FT
