Tim Harford (we are reading a chapter out of his book this week) has a column in Financial Times called "Dear Economist," where people write him about personal problems and he answers with his economic perspective. Here is an example of a question that he recently published:
Recently I was waiting, baby in pushchair, for the bus. The driver refused to let me on unless the pushchair was folded up, then sped on leaving me stranded. It would only have taken a moment to fold up the pushchair. Is this efficient?
Mary McLaren, Hackney
What do you guys think? Again, make sure it is from the economic perspective of efficiency. I will post Harford's response soon so you can see how your response compares and whether you agree.
