Land Productivity and Plot Size : Is Measurement Error Driving the Inverse Relationship?

This paper revisits the decades-old puzzle of the inverse plot-size productivity relationship (IR), which states that land productivity decreases as plot size increases. While existing studies define land productivity or yields as self-reported production divided by plot size, we consider an alterna...
