Two approaches to measure Farm Net<br />
Income<br />
Concerning the Farm Net Income calculation<br />
two main approaches were used: Neoclassical<br />
Approach (NA) and Peasant Farming Approach<br />
(PF) (Table 20). One is based on the Neoclassical<br />
theory principles, which assume farms to<br />
pursue (as capitalist enterprises would) profit<br />
maximisation and operate under competitive<br />
market conditions (i.e. output/input price takers,<br />
high number of suppliers, zero information<br />
and transaction, markets not influenced by<br />
producers/consumers, no entry or exit barriers,<br />
etc.). A second approach takes into account<br />
key assumptions introduced by Chayanov (1966<br />
= Farm Net Income<br />
+ Off-farm Net Income<br />
Farm Net Income (FNI) = Output Value – Variable Costs – Fixed Costs<br />
Farm Gross Margin (FGM) = Output Value – Variable Costs<br />
Farm Net Cash Income (FNCI) = Value of Sales – Variable Costs in cash<br />
Output Value (OV)<br />
= Value of Sales<br />
+ Value of Consumption<br />
+ Value of Stocks<br />
Value of Sales = Production for Sale * Unit Price<br />
Value of Consumption = Production for Consumption * Unit Price<br />
Value of Stocks = Production for Stock * Unit Price<br />

= Production for Sale<br />

+ Production for Stock<br />
= Crops for Sale<br />
+ Livestock for Sale<br />
= Crops for Consumption<br />

translated from Russian and German editions<br />
first published in 1920) concerning peasant<br />
farming. The latter argues that the goal of peasant<br />
household is reproduction rather than profit<br />
maximisation (Ellis 1993, p. 53).<br />
Sales under both approaches are valued at<br />
market price (as observed in the survey). While<br />
under the Neoclassical approach, consumption<br />
and stocks are also valued at the market price,<br />
under the Peasant Farming approach, these two<br />
components of the output are assumed to be<br />
valued at a 10% higher than the market prices.<br />
Several studies deal with the evaluation of the self<br />
subsistence production, where the output value<br />
of the staple food was generally valued near retail
