On a wall in Greg LeRoy's office is a frame with a custom-engraved wrench and a photo of workers in front of the Diamond Tool and Horseshoe factory in Duluth, Minn. It's from his days helping unions fight plant closings — when he first started digging into the convoluted financial relationship of corporations and local governments.

These days, LeRoy is the guy to call if you want to know about corporate subsidies. Lately, his phone has been ringing about one company in particular: Amazon.

The stock market hit a new record today. For a brief time, the Dow Jones industrial average went up past 23,000 points. NPR's Alina Selyukh reports.

ALINA SELYUKH, BYLINE: Trying to predict markets is not easy, but today's movement was.

Every user who had a Yahoo account in August 2013 was likely affected by its massive hack, the company's parent, Verizon, said Tuesday.

This latest disclosure triples the number of accounts compromised by the major 2013 data breach that the company disclosed late last year. At the time, Yahoo said hackers had stolen data associated with 1 billion user accounts; the new disclosure escalates that number to 3 billion.

An official from Toronto has called Amazon's search for the second headquarters "the Olympics of the corporate world."

It's a unique situation of its kind and scale. Typically, cities and states vie for factories or offices behind the scenes. This time, Amazon's public solicitation of bids from essentially all major metropolitan areas in North America has prompted reporters and analysts across the continent to run their own odds on potential winners.

What's at stake?

Early leaks of new designs had stirred anticipation for Apple's new smartphone — and on Tuesday Apple delivered on all the predictions with a $699 iPhone 8 and a $999 special-edition iPhone X (as in "10"). The 10th-anniversary iPhone is the biggest redesign in years, with an all-screen front that eliminates the home button and can use facial recognition to unlock the display.

But it was the new Apple Watch that got Wall Street — and many tech observers — excited on launch day.

Back in 2007, the hype around Apple's new phone was all about the keyboard — or lack thereof.

"In fact, some experts think the days of the telephone keypad are numbered," NPR's Laura Sydell wrote in advance of the release of the very first iPhone by Steve Jobs. It's fair to say, the forecast triumph of the on-screen keyboard has proved true (RIP BlackBerry Classic).

Three executives of the credit-reporting agency Equifax sold nearly $2 million worth of company stock within days of a massive data breach potentially affecting 143 million Americans — one that wasn't publicly disclosed until more than a month later.

In a statement, Equifax says the executives "had no knowledge that an intrusion had occurred at the time they sold their shares."

Food prices in America were down for the longest period in about 60 years.

Wait, what?

It's not something that shoppers seemed to have noticed much.

"Are you serious? Really?" says Michelle German, holding a bag of groceries and wine at a Harris Teeter store in Washington, D.C. "I just spent about $40 dollars on four items and I'm like, wait, how did I spend that much money?"
