“Just Eat the Darn Quinoa…”

Farmers in Bolivia feel the pressure of global markets to grow large quantities of this agricultural produce, sometimes at the compromise of their own food and nutritional security. Unforeseen and increasingly high demands and limited supply cause for perpetual market tensions with farmers trying to keep up with an economy they were forced to participate in. These factors, coupled with standard within-country inequality, skewed export/import dynamics, and capitalist trade practices that remain in the favor of the powerful player in these dynamics – the core consumer – cause for Bolivian farmers to experience various negative externalities. Furthermore, environmental factors also must be considered, since growing such large amounts of quinoa has been causing for the degradation of the Andean soil: even the FAO outlines concerns for biodiversity, while otherwise touting the phenomenon.

While efforts have been put in place by farmer unions, cooperatives and development initiatives to mitigate some negative effects on the primary producers of quinoa, they have not been enough to protect the food security of these Andean farmers. Increased consumer consciousness is therefore essential in ensuring that these farmers don’t continue to suffer because of Western dietary fads.

From an articleblog post by Aarushi Bhandari on The Society Pages, in which the author makes a series of dubious claims about quinoa.

Indeed, there is no evidence supporting the claim that quinoa consumption in the North/West/whatever-is-the-appellation-du-jour-for-rich-countries threatens food security anywhere else. None.

Why a Soda Tax Is Unlikely to Work: Yours Truly in the Washington Post

Several European countries also tax sugary drinks, but, as with Mexico, it’s tough to tease out whether, or how much, the taxes affect consumption. Marc Bellemare, assistant professor in the department of applied economics at the University of Minnesota, took a close look at soda sales data (from Euromonitor International, which tracks sales of an astonishing array of food items around the world). He concluded that, depending on how you parse the data, you could claim anything from no impact to about a 2.6 percent decrease.

“In academic parlance, the results are not ‘robust,'” Bellemare says. …

The lack of a clear correlation doesn’t mean sugary drinks aren’t implicated in obesity and disease. … We cannot be sure, not by a long shot, that a tax on soda will result in improved public health.

From a longer column by Tamar Haspel in the Washington Post last week. A few weeks ago, Tamar got in touch with me telling me she had gotten her hands on Euromonitor data for soda sales (supplemented with information about soda taxes in Europe), and she asked me whether I could figure out whether taxes appeared to cause any decrease in soda sales.

Splitting a Random Sample Along Some Control Variable to Get at Treatment Heterogeneity (Updated)

I teach the second-year PhD research seminar in the Department, and it’s that time of year again when students have to submit a draft of their second-year paper. In case you are not familiar with a second-year paper, it is essentially the widespread practice in applied economics and economics department of having students who are done with their first-year courses to write an entire publishable paper from start to finish.

As such, teaching the second-year paper involves reading a lot of drafts. One of the drafts I read last week did something that always baffles when I see it. This might be a simple question whose answer is obvious, so bear with me, but the practice is so common that I thought I would ask readers whether it is me who is missing something. The practice is as follows (note that I am positing all this for observational data, not experimental data):
