What to watch for Chinese ride-hailing giant Didi Chuxing lists on the New York Stock Exchange today, and is [expected to raise more than $4 billion]( in one of the biggest tech IPOs this year. The debut will test investorsâ appetite for the unprofitable ride-hailing industry, and for Chinese tech champions in the face of rising China-US tensions. Some areas of speculation: How will shares perform? Last week, Chinese online grocer Missfresh met a [muted Nasdaq]( at its debut, a sign of concerns about the fierce competition among Chinese tech firms. This doesnât bode well for Didi, which also lives in [the shadow of Beijingâs antitrust scrutiny](. How much can Uber make?

Charting US restaurant worker pay Tables are filling up again in US restaurants, but restaurant employment itself lags behind. In May, 186,000 jobs were created in food services and drinking places, according to the US Bureau of Labor Statistics, which means employment in the sector is still down 12% compared to pre-pandemic levels. While some employers are raising wages to entice workers back, others are offering one-time bonuses, a signal that businessesâwhich are balancing pent-up demand with a lack of staffâperceive the employee shortage as a temporary problem. Some experts argue that wage growth is [about the same as it would have been]( if the recession had not occurred. [A line chart showing the steadily decreasing wages for US leisure and hospitality employees from 2008 (below $11 an hour) to 2020, where it dips slightly, then sharply reaches towards $20 an hour in the last quarter] What are we going to do with all this plexiglass? [plexiglass upcycled] Connor Shinn/Iowa State University The transparent, shatter-resistant material spent much of 2020 being in impossibly high demand. Now, as parts of the world snap back to normalcy, facilities managers are puzzling over what to do with their stockpiles of plexiglass. Industrial design students at Iowa State University have spent the past semester grappling with this problem, [creating jewelry, desk accessories, and even furniture]( from acrylic partitions they found around campus (that handy organizer above is the work of student Connor Shinn). Fashion designers are no stranger to upcycling, but industrial designers typically strive to meet the consumer expectation of fresh-out-of-the-box perfection. Weâll need to appreciate the beauty of imperfect design to save materials like plexiglass from the landfill. ⦠While the students at Iowa State keep you from losing sleep over the plexiglass fate, Quartz can keep you from losing sleep just in general.
