11. Supply (depends) on output prices and input prices. An increase in the price of an input (results) in a reduced use of that input. A reduction in the price of an output (has) the same effect as an increase in the price of input, that is, a reduced use of input. The input use (won't change), provided output and input prices (rise) or (fall) by an equal percentage. Thus, the effect on output of a decrease in product prices (can be neutralized) by an equal percentage decrease in input prices. Sometimes the prices of inputs and outputs (change) together. For example, a fall of livestock product prices (reduces) the demand for feed grains. This (leads) to a fall in the price of feeds, that is, the price of inputs.
