The labor force of an island country consists of only six workers. There are only two industries in this island, one producing X (for example, goods) and the other producing Y (for example, services). The following graph shows the production possibilities frontier (PPF) for this island country. It shows the effects on the production of X and Y from shifting workers from one industry to another one worker at a time. For example, suppose that currently X = 1 and Y = 125. Now, if we transfer one worker from Y to X production, the production of X will increase to X = 2 and the production of Y will decrease to Y = 110. There are no externalities in production.

Let's analyze the effect of a technological advance on the marginal social costs of production. Currently, the marginal social cost of increasing production of X from 2 units to 4 units is units of Y. Now suppose that, over a span of several years, a technological progress takes place in the X industry so that for each level of Y production the country can produce twice as much X as before. No technological advance takes place in Y production. After this technological progress in the X industry, the marginal social cost of increasing production of X from 2 units to 4 units becomes units of Y. Why do you think is the reason for this result? Food for thought: What will be the effect of a technological advance in the X industry on the marginal social cost of increasing the production of Y in terms of sacrifices of X? Why? Who knows, the questions about these reasons may come up in one of the exams. So, you'd better try to figure them out
