Assume Firm Y's production function is given by the following Cobb Douglas equation

Q = 0.5 x L^0.6 x K^0.5

where L denotes labor and K denotes capital.

The production function exhibits (increasing/decreasing/constant) returns to scale.

1. If labor hours increase by 10%, what is the percentage change in output (provide a numerical answer)?

2. If capital decreases by 10%, what is the percentage change in output (provide a numerical answer)?

3. If the number of labor hours increases by 10% and the number of hours of capital used decreases by 10%, what is the percentage change in output?

Solution Summary

This solution analyzes the given production function and predicts the effect of changes in input values on output level.

Solution Preview

The production function exhibits (increasing/decreasing/constant) returns to scale.

Sum of exponents of L and K=0.6+0.5=1.1

In the case of the Cobb Douglas function if sum of exponents is greater than 1, production function exhibits increasing returns to scale.

If labor hours increase by 10%, what is the percentage change in ...
