Regional purchase coefficients (RPCs) are often seen as the weakest link in input-output modeling systems such as IMPLAN. In IMPLAN the RPCs are estimated either by the supply-demand pool (SDP) method, which ignores cross-hauling, or by econometric methods, based on 1977 data. Yet, how much...

Two cost and efficiency measures, crop expense per acre and feed and crop expense per hundredweight of milk, are compares on a cash and accrual basis. Records from 470 dairy farms were used for the comparison. Serious errors would be introduces by using the cash calculation on some farms.
