Automation, broadly referring to the adoption of machines and computers in the production process has become increasingly more popular across many sectors and countries. For example, the market for industrial robots has experienced a dramatic expansion in the last couple of decades, as shown in Figure 1.

At the same time, the prices of labour and robots have been changing. The case of the US manufacturing sector in the last few decades is shown in Figure 2.

Now, consider Bruno, who owns a small manufacturing firm and produces windscreens for automobiles. Currently Bruno uses two robots and ten workers including Angela in his production.

Draw the production function of Bruno's firm. The diagram should have the number of workers on the horizontal axis and the number of windscreens on the vertical axis. Illustrate the effect of Bruno's decision to use more robots on his production function. Briefly explain the diagram drawn as well.
