Dear Economist,
I live in a student house with six others. All of us drink milk, some a lot, and some a little. Only three of us buy milk, and we buy three different varieties, meaning my preferred type can quickly run out.
Worse, my variety (semi-skimmed) seems to be the second preference of everyone else.
Free riding is common, but I don’t want to spoil the atmosphere with strict rules and enforcement mechanisms. What course of action would you recommend?
