You are the benevolent ruler of an island economy, which cannot
trade with other countries. You have complete control of the
island’s workforce. The workers can either produce goods to be
consumed, or capital (in this case, tools and machinery).
a) Assume that in year 1, you decide to direct all production
effect into goods. Also assume diminishing marginal product of
labour. Sketch your initial production function, with hours worked
per person per day on the x-axis, and total output of goods on the
y-axis. Turn this into a feasible set. Show your optimal choice of
how workers spend their time in year 1, by sketching in
indifference curves for a representative worker.
b) You decide that, in year 2, you will tell your workers to
spend half of their time making capital, and half making goods.
Show the impact on your total goods production in year 2. Why might
you do this?
c) Assume that the capital you have produced lasts forever. Now
explain what you would choose to produce in year 3. Sketch the new
feasible frontier and optimal choice.
