The general form of the PAR production function is as follows : Y = A * [ c * ( D ^ \ − a − L ^ \ − a ) / ( ( D/L ) ^ \ - a * c-1 ) ] ^ \ − ( 1/a ) ( a ≠ 0 ) ( c ≠ 0 ) ( D ≠ L ) = A ** [ c * ( D ^ \ − a − L ^ \ − a ) / ( - a * ln ( D/L ) ) ] ^ \ − ( 1/a ) ( a ≠ 0 ) ( c = 0 ) ( D ≠ L ) = A * D ^ \ ( ( 1-c ) / 2 ) * L ^ \ ( ( 1 + c ) / 2 ) ( a = 0 ) ( -1 ≤ c ≤ 1 ) ( D ≠ L ) = A * D ( D = L ) If a = -1 , thenY = A * c * ( D-L ) / [ ( D/L ) ^ \ c-1 ] ( a = -1 ) ( c ≠ 0 ) ( D ≠ L ) = A * ( D-L ) / [ ln ( D/L ) ] ( a = -1 ) ( c = 0 ) ( D ≠ L ) In the above equation , Y is the physical output of production , D is input 1 , L is input 2 , “ c ” is the distribution limit parameter and “ a ” is the substitution parameter .
