No 176: Competition!!!!!!

IT'S been a long time since this blog had its last competition, so I thought it was time for a new one. The competition will be an .......................

ECONOMICS VEGETABLES COMPETITION

Here's the story. Last year, a student started talking about

CUCUMBER FIRMS

It took me a while to realise that they meant "incumbent firms" (firms that are already in a particular market when other firms are trying to enter it).

We all thought this was very funny, so when we got to our next topic, this is how I titled the Powerpoint:

TRADE ONIONS

So, to enter the competition, please post suggestions about other economics vegetables.
An interesting book about Economics will be the prize for whoever I think has the funniest suggestion.
