This paper shows that using yields may not be informative of the relationship between farm size and productivity in the context of small-scale farming.

We use high-frequency data on fine particulate matter air pollution (PM 2.5) at the locality level to study the effects of high pollution on labor supply decisions and hospitalizations for respiratory disease in the metropolitan area of Mexico City. We document a negative, non-linear...
