No Need to Fear the Horse Meat Burger

Today, the Oklahoman (the largest newspaper in the state), ​ran an editorial I wrote on the European horse meat scandal.  I also touched on the consequences of the end of horse slaughter in the US.  Here are a few snippets:

An expanding European horse meat scandal has left many Americans wondering whether the same could happen here. Americans are unlikely to find a horse burger. Before celebrating, it might do some good to learn why.

Because horse slaughter ended in the US in 2007.  The consequences?

Unable to find a home for aged or crippled horses, ranchers faced high prices for euthanasia and disposal. Many horses were abandoned and left to starve. Investigations into horse abuse, for example, increased 60 percent in Colorado following slaughter cessation. Our research suggests that slaughter cessation caused a 36 percent drop in horse prices at a major Oklahoma auction and resulted in losses of $4 million per year in the yearling quarter horse market.

and

Americans are unlikely to find horse meat on their plate because we no longer produce any. It's possible that mislabeled products could be imported, but about 90 percent of the beef eaten by Americans is homegrown. If mislabeled products were found here, the answer wouldn't be, as we've seen, to ban horse slaughter. However much we are culturally predisposed to abhor eating horse, the reality is that it's safe and perfectly tasty. Just ask the French

and:​

. . . if a food retailer lies, there are legal remedies. The mere knowledge of liability, not to mention lost reputation, incentivizes truth telling. More vigilance might have stopped the faux beef sellers in Europe. But no government can prevent us from all harm. Nor should we want it to. Vigilance is costly and our governments are already doing too much.

in conclusion

The lesson from these equine scandals isn't necessarily that the government should have been doing more. Rather, politicians should learn what every good horse intuitively knows: Look before you leap.

The Food Police

My new book The Food Police: A Well Fed Manifesto about the Politics of Your Plate officially goes one sale April 15, 2013.  You can pre-order a copy now in hardcover or kindle or nook.

​To whet your appetite, the front and back covers of the book jacket are below

Here is an early review from Kirkus, the book review magazine:​

Why Do People Want Local Food?

That was the question motivating some research ​I conducted with a couple co-authors that is forthcoming in the journal Ecological Economics.  A lot of the previous research in this area had simply interviewed people at farmers markets and asked why local food was desirable.  This sort of approach is problematic for a number of reasons.  For one, people at farmers markets are not a random sample of the population and likely have different preferences and desires than the average consumer.  Another problem: we don't always know why we do what we do even though we're good at making up post hoc stories.  

To address these challenges, we conducted some research with a randomly recruited group of German consumers (located in Bonn Germany) who spend real money to buy real food.  ​Our research strategy was to pick two different kinds of foods for which freshness is related to distance traveled for one but not another.  The idea is that this would let us sort out the extent to which desires for freshness are driving desires for local food.  We picked apples (where distance traveled is related to freshness) and wine (where distance traveled is not related to freshness) and asked how much people were willing to pay (WTP) for different apples and bottles of wine that had traveled different distances.  

Here is our key result:​

These findings imply that ‘a mile is NOT a mile’. The data in Fig. 1 and Fig. 2 indicate that discounts for km traveled (especially in percentage terms) are higher for apples than for wine — a fact that suggests freshness is one driver of demand for ‘local’. In fact, comparing the change in bids across apples and wine suggests that of the total drop in WTP that occurs from moving from 20 to 1000 km, about 28.5% can be attributed to freshness (i.e., (1 − 0.35 / 0.49) ∗ 100 = 28.5%). In the following we will present additional evidence that people perceive freshness to be more related to distance traveled for apples than wine . . .

The (Not So) Extraordinary Science of Addictive Junk Food

​The New York Times Magazine ran a feature story this weekend by Michael Moss entitled The Extraordinary Science of Addictive Junk Food.  There is really so much that could be said about this piece (and probably the forthcoming book by Moss), but for now, I'll just leave you with the letter I sent to the editors of the NYT:

Michael Moss’s over-wrought piece on the “Science” of addictive junk food misses some key facts.  Around the time the executives of Big Food were in their clandestine meeting, regular folk were voluntarily cutting back.  CDC data reveals that the average weight of 40-49 year old women fell 0.2 lbs over the last ten years.  In the last four years, the average weight of men in this age range went down 1.7 lbs (women’s weight fell by 3.3 lbs).  It seems that the addictions cooked up by nefarious food scientists are waning.  Or maybe they weren’t addictive at all.  I gave up regular Dr. Pepper in 2002 when my pants began fitting too snugly, and I can’t recall any withdrawal symptoms.  If Big Food isn’t in their lab trying to create new tasty treats I want to try again and again, I’m not sure why they exist.​
