Since economics is the science of never looking at enough variables, I thought I would try to figure out why business at Subway sandwich shoppes is running counter to downward trends. Googling “Subway success,” I ran into the following hypotheses (1, 2):

  • They install Energy Star equipment.
  • The large corporate structure avails reduced-rate startup costs and wholesale purchasing prices.
  • Private ownership allows leadership to focus more on customer satisfaction than paperwork.
  • One can fight the obesity crisis by eating plain, dry sandwiches.

What do you think?
