I'm a fan of National Public Radio's podcast 'Planet Money'. Last week they ran a 15 minute episode on how the distribution of produce donated to food banks in the US was transformed by an ingenious market solution. By the way, that's an economic market, not a produce market.
The issue was illustrated by the need to get fresh fruit and veg to Alaskan food banks, when the perception was that long-distance chilled transportation was problematic. Hence an abundance of pickles in Alaskan food banks and an oversupply of potatoes in Idaho.
