EX: In an enterprise, the total wear and tear expenditure is $ 100000 . The materials expenditure is $ 300000. Find the total variable capital , provided that the total value of products is $ 1000000 and the rate of surplus value is 200%
Here is the way we'll solve this problem :
- The total constant capital is : C = 100000 + 300000 = $ 400000
- The total value of products : W = C + V + M
=> 1000000 = 400000 + V + M
=> V + M = 600000 (1)
- The rate of surplus value is : m' = m/v = 200% => m/v = 2 => M/V = 2 or M = 2V (2)
- From (1) and (2) we have : 3V = 600000 => V = $200000
- So the total variable capital is $ 200000.
He he, so our problem has been solved.
Here is another example: In an enterprise, there are 100 workers. In a month, they produce 12500 units of products. The total constant capital is $ 250000. The value of labor of each worker per month is $ 250. The rate of surplus value is 300%. Find the value of ONE unit of products and state its structure.
Here we go:
- The total variable capital is : V= 250.100 = $ 25000
- The rate of surplus value is : m' = m/v = 300% => The total constant capital is : M = m'.V = 3. 25000 = $ 75000.
- The total value of products is : W = C + V + M = 250000 + 25000 + 75000 = $ 350000
- The value of ONE unit of products: w = c + v + m = 350000/12500 = $ 28 (This is the value of ONE unit of products created by one worker).
- About the structure:
+ the amount of products a worker creates in a month: 12500/100 = 125 (units)
+ the variable capital spent for one worker: v = 250/125 = $ 2
+ the surplus value created by one worker per one unit of poducts: m = 75000/12500 = $ 6
=> the constant capital spent for ONE unit of product: c = w - v - m = 28 - 2 - 6 = $ 20
* In conclusion: + the value of ONE unit of products is $ 28
+ the structure is: c = $ 20, v = $ 2, m = $ 6
Phew, I've just introduced the two examples of Political Economy problems . Hope you'll find them useful.
[These examples come from the exercises the lecture gave us]
