Farm financial structure may affect both short- and long-run input usage,thereby affecting farm efficiency. Any inefficiencies arising from thechoice of inputs can be magnified over time as credit constraints continueto affect input usage. In a panel of 54 North Dakota crop farms, efficiencyand debt structure were related. Intermediate debt was found to bepositively related to farm technical efficiency, and short-term debt wasnegatively associated with technical efficiency. Use of intermediate-termdebt was positively associated with farm-scale efficiency, whereas nosignificant relationship was found between short- and long-term debt andscale efficiency.
