No Free Lunches but Plenty of Cheap Ones. Lawrence Summers, February 8, 2016, Opinion. "Tradeoffs have long been at the centre of economics. The aphorism “there is no such thing as a free lunch” captures a central economic idea: you cannot get something for nothing. Among the many tradeoffs emphasised by economists are guns v butter, public v private, efficiency v equity, quality v quantity or cost and short-term v long-term performance." Link
