A hat tip to a fellow presenter on our revision workshops in London whose acronym to remember some of the effects of monopoly power in markets struck a chord with me

SPEW

Service - does the lack of competition affect the quality of service to consumers?
Prices - how high are prices compared to competitive / contestable market
Efficiency - productive, allocative and dynamic
Welfare - what are the overall welfare outcomes? Is there a net loss of welfare in markets dominated by businesses with monopoly power?

Are there anymore useful revision acronyms out there that you use? Please share them via the blog!
