The Invisible Helping Hand by Ray Fisman and Tim Sullivan at Slate. Ray Fisman is the Slater family professor in behavioral economics at Boston University. Tim Sullivan is the editorial director of Harvard Business Review Press. Excerpts:
This involves "America’s Second Harvest (now called Feeding America),
a clearinghouse that takes surplus food from grocery stores, food
producers, and farms and distributes it among a network of food banks
across the country."
"the clearinghouse worked something like this: A donor company, say
Kraft, would notify Second Harvest that a load of macaroni and cheese
was available for pickup. Second Harvest management would then offer the
shipment to one of 200 food banks around the country based on need,
proximity to the pickup locale, and a formula that dictated how many
pounds of donations each affiliate was entitled to each year. The local
food banks were responsible for shipping the donation. Once the food
arrived at the affiliate’s warehouse, volunteers sorted it, entered it
into a computerized grocery list, and made it available for local
charities that served the hungry and poor."
"it was far from optimized. Food banks might provide feedback on their
likes and dislikes, but at its core, the Second Harvest allocation still
resembled 1960s-era Chinese central planning (which, free-market
economists will note, helped to cause the Great Famine of 1959–61)."
There were problems like "sending potatoes, unbidden, to a foodbank in Idaho that already had
warehouses full. Or delivering milk to a bank that didn’t have the
refrigeration capacity to store it and so would end up throwing it away.
In fact, Second Harvest would sometimes turn down food donations from
giant food companies because they weren’t sure where to send it. Second
Harvest was also, at the time, treating different kinds of food as the
same."
"Early on, Prendergast (an economics professor) and his colleagues brought up the idea of using
something like a market instead. As Prendergast imagined it, the
currency in a Second Harvest market would be points, or shares, that
would be distributed among the member food banks. These shares could
then be bid on food donations as they arrived in Second Harvest’s system
each day. In a sense, nothing would change. Kraft would offer a
container load of mac and cheese, and it would be allocated to a food
bank affiliate to feed the hungry. But instead of being distributed by
Second Harvest’s central office, the food bank that wanted it the most
would express that preference by parting with precious shares to get it."
"Under their proposed system, no money was to change hands. Kraft,
Kroger, and others were donating their food, not selling it (though they
did receive a tax write-off), and America’s Second Harvest, itself a
charity, wasn’t taking any cut of the proceeds. A market or marketlike
system would simply be a better way of efficiently matching the supply
of food donations to food bank needs."
"It soon became clear to the Booth team that the main barrier to
improving Second Harvest’s distribution system wasn’t devising an
efficient market. The bigger challenge was making it seem fair to
skeptics"
"Under the initial proposal, shares were to be allocated based on the
poverty head count in each affiliate’s service area. The same food banks
with the staff to track food auctions in real time were also located in
population-dense urban centers, which would entitle them to a higher
allocation of shares. They’d always end up getting the good stuff."
"Instead of an eBay-style
system of shipments that appeared and expired in real time based on the
flow of donations, offers accumulated throughout the day. Then, the
following morning, each food bank would receive the full list of items
up for bid to consider. Every food bank would have the opportunity to
review the listings and make its best offer on each one through a
sealed-bid auction. The winning bidder would send a truck to collect the
donation, and the shares from its winning bid would get split up among
the rest of the food banks in the Second Harvest network.
This last point might not seem like a big deal: If everyone gets some
extra shares, then it won’t make anyone richer; it’ll simply make
prices rise through more aggressive bidding. But, Prendergast recalled,
it totally changed the psychology of losing an auction from “the rich
bastard outbid me again” to “that chump overpaid again—more shares for
me!”"
"It turns out that there’s a Depression baby inside of each of us: Food bank presidents, the
market designers discovered, were hoarders of shares. To keep the
market from dipping into a deflationary spiral, Prendergast needed to
pump extra shares into the market to encourage bidding. There was also
the ebb and flow of goods into it to consider. Some days, Kraft might
dump half a dozen container-loads of mac and cheese into circulation;
other days there’d be none. If everyone used their points to bid on mac
and cheese, the prices of, say, potato chips and broccoli would plummet,
not because broccoli was suddenly worth less, but because of a
temporary surge in the supply of more desirable donations. So extra
shares would need to be put into circulation to prop up prices—lest
Arnold see last week’s lower price of potato chips and bid too timidly
on them, misinterpreting short-run price declines as permanent ones.
Similarly, in a dry spell of donations, shares would be withdrawn from
the market: Since there was so little to bid on, there would be a run-up
in prices unless the number of shares also declined.
Another unanticipated consequence of “marketizing” food
distribution—this one positive—is that prices gave Second Harvest’s
leadership a sense of what kinds of donations were most valued by
affiliates. Prices revealed that peanut butter and noodles were the two
food types most valued by food charities. Frozen chicken wasn’t far
behind. They’re all storable, calorie-dense, reasonably nutritious foods
that people will actually eat. In a free-market economy, these signals
would motivate suppliers to ramp up production of popular items or
motivate new entrants to enter the popular market. In the charity
context, popularity didn’t matter to the suppliers, but it motivated the
central office at Second Harvest to hunt more aggressively for donors
of frozen chicken and peanut butter, less so for potatoes, and least of
all for potato chips. In fact, chips, a bulky, fragile junk food, are so
little valued by food banks that sometimes their prices turn negative,
so a food bank receives shares in exchange for the cost and hassle of
picking up the shipment. Kale and broccoli were better than Doritos, but
not by much; you can’t feed the hungry if all you give them is stuff
they can’t cook or won’t eat."
"the annual supply of food donations increased by 50 million to 100
million pounds as a result. Twelve million pounds can be traced directly
to the market itself, in the form of excess donations that flush food
banks placed into the market in exchange for shares. That’s 12 million
pounds of food that would otherwise have been wasted. Based on his
analyses, Prendergast estimates that if anything, the smaller food banks
benefited the most from the new system."
