Chapter 11, Problem 20P
A bridge is to be constructed now as part of a new road. Engineers have determined that traffic density on the new road will justify a two-lane road and a bridge at the present time. Because of uncertainty regarding future use of the road, the time at which an extra two lanes will be required is currently being studied.
The two-lane bridge will cost $200,000 and the four- lane bridge, if built initially, will cost $350,000. The future cost of widening a two-lane bridge to four lanes will be an extra $200,000 plus $25,000 for every year that widening is delayed. The MARR used by the highway department is 12% per year. The following estimates have been made of the times at which the four-lane bridge will be required:
In view of these estimates, what would you recommend? What difficulty, if any, do you have in interpreting your results? List some advantages and disadvantages of this method of preparing estimates.

5. We learnt the following equation in the class: Ak = sy - (n + 8)k where y = ko. Now, I
transform this equation into: Ak/k = sy/k - (n + 8). I want you to use a diagram to show the
steady state solution of this equation (In the diagram, there will be two curves - one
represents sy/k and one represents (n + 8). In the steady state, of course, Ak/k = 0). In this
diagram, the x-axis is k. What will happen to this diagram if the value of n increases?

3. A country has the following production function: Y = K0.2L0.6p0.2 where Y is total
output, K is capital stock, L is population size and P is land size. The depreciation rate (8)
is 0.05. The population growth rate (n) is 0. We define: y = ½, k = 1 and p = . Land size
is fixed.
