Abstract: Using two nationally representative surveys, we find that people in China’s historically rice-farming areas are less happy than people in wheat areas. This is a puzzle because the rice area is more interdependent, and relationships are an important predictor of happiness. We explore how the interdependence of historical rice farming may have paradoxically undermined happiness by creating more social comparison than wheat farming. We build a framework in which rice farming leads to social comparison, which makes people unhappy (especially people who are worse off). If people in rice areas socially compare more, then people’s happiness in rice areas should be more closely related to markers of social status like income. In two studies, national survey data show that income, self-reported social status, and occupational status predict people’s happiness twice as strongly in rice areas than wheat areas. In Study 3, we use a unique natural experiment comparing two nearby state farms that effectively randomly assigned people to farm rice or wheat. The rice farmers socially compare more, and farmers who socially compare more are less happy. If interdependence breeds social comparison and erodes happiness, it could help explain the paradox of why the interdependent cultures of East Asia are less happy than similarly wealthy cultures.
