I've got a tangential question about efficiency that someone might be able to help with: The perceived wisdom is that capitalist systems result in efficient companies, because they beat the inefficient ones. So for example we have Apple making tons of money because they were better at what they were doing than (most) of their competitors. So the end result of a bunch of competition is an efficient company ... but how efficient was the process of getting to that end result? So for example once you count all the failed competitors in a given market, the bankruptcies, redundancies, people who invested their time and money in failing businesses. Has anyone measured the overall 'efficiency' of a competitive system whittling down the competitors to the viable ones? Is there a name for this concept in economics? I'm wondering because efficient end result =/= efficient process, and the process itself must have a cost to society etc.
