摘要：This study uses farm-level data from the Illinois Farm Business Farm ManagementAssociation to determine whether the variability of net farm income is significantly influenced byfarm size, financial structure, and other structural characteristics of farm businesses. Theeconometric results indicate that under a cross-sectional model the relative variability of real netfarm income is not significantly influenced by farm size, measured either by acreage or value offarm production. However, under a time series cross section model, periodic variations in farmsize, along with differences in the relative crop price received, crop yield, degree of enterprisediversification and geographic location, can significantly influence changes in farm incomevariability.
