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 />

Farm Gross Production<br />

Production for Sale<br />

Production for Consumption<br />

= Production for Sale<br />

+ Production for Consumption<br />

+ Production for Stock<br />

= Crops for Sale<br />

+ Livestock for Sale<br />

= Crops for Consumption<br />

+ Livestock for Consumption<br />

Production for Stock = Crops for Stock<br />

Input Costs (IC) = Variable Costs + Fixed Costs<br />

Variable Costs (VC)<br />

Fixed Costs (FC)<br />

= Costs of Household labour<br />

+ Costs of Hired labour<br />

+ Costs of Seeds<br />

+ Costs of Livestock maintenance<br />

= Costs of Land rent<br />

+ Costs of Tools<br />

+ Costs of Livestock purchase<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
