As the story would have it, Peruvian producers who relied on the pseudo-grain struggled to eat it due to rising quinoa prices that pushed its cost higher than that of chicken and other staples.But that wasn’t borne out by the numbers. Using a database of Peruvian household information that includes crop and consumption information, the economists were able to look at the relationship between rising quinoa prices and what Peruvian families ate and grew. They compared three groups: people who don’t grow or eat it, people who eat it but don’t grow it, and people who do both.
They found that as the purchase price of quinoa rose, so did household welfare in all three groups. The welfare of those who produced and consumed quinoa rose more quickly than the other two groups, but even families who didn’t produce quinoa saw an effect.
That suggests that rising prices are good for Peruvians across the board.
