Morning roundup

The week's closing of the browser tabs brings some fun:

• Supermarkets find consumers nicking the shopping carts when they no longer can get plastic bags. Carrying bags around everywhere just in case you might realise you need to do some shopping might work for some people (and hooray for them!) but not for everyone. I wonder if anybody is tracking how many of the reusable bags are winding up in the tips because nobody needs the dozens of bags that easily accumulate - they're of little use as bin liners.


• Oliver Hartwich says it's time for a little game theory on Brexit


• SmokeFree Action UK's poster encouraging pregnant women to vape instead of smoke sends the right message. Nice. 


• In similar line, I liked this chart in the Annual Review of Public Health earlier this year. I continue to wonder why we aren't looking at a risk-proportionate excise regime where less harmful tobacco products would carry far lower excise than smoked tobacco. 
  


• Alex Tabarrok points to Matt Levine's proposal to free people to invest in things the SEC thinks are dumb investments. Basically, you sign a form agreeing that it's a dumb investment, an SEC employee slaps you hard across the face, then you're allowed to invest. Less rigamarole than the 'accredited investor' regime. 


• The economics of apologies. The best form of apology compensates the harmed party. 


• Trackless trams. Neat. Allows for far more flexibility, and is much cheaper than putting in rails. 


• MBIE notes the advantages of flexible workplaces with coming technological change. It'll all be ruined if we get fair pay agreements specifying terms and conditions across entire industries and occupations, but nice to think about.
