Those of you who follow a vegetarian diet, or even those of you who are foodies, likely have had quinoa sometime within the last few months. Once eaten mostly by people in Peru and Bolivia, and a reputed favorite of the Incas, quinoa, a highprotein grain, has found a large market among food aficionados. Growth in vegetarianism effectively shifted the demand curve for quinoa to the right.

With an upward sloping supply curve, this shift in demand resulted in increased prices. Farmers grew richer, whereas some local consumers found themselves facing higher prices for a staple product. Over time, these higher prices encouraged more farmers to enter the quinoa market. This shifted the supply curve to the right, helping to moderate the price increases. But quinoa growing turns out to be a tricky affair. Quinoa grows best in high altitudes with cold climates. It thrives on soil fertilized by the dung of herds of llama and sheep. Thus, while supply clearly shifted with new farmer entry, the particular nature of the production process limited that shift and, in the end, despite the supply response, prices increased.
