Answer:
Answer to this is both option (i) and option (iii).
Explanation:
Change in technology generally affects the change in productivity as well as the change in labor demand. In the case of Labor-augmenting (improving) technology, it is found that the positive change in technology leads to the increasing marginal productivity of labor. This increase of marginal productivity of labor shifts the labor-demand curve towards right. Thus, Labor-augmenting (improving) technology causes marginal productivity of labor to increase which further leads to shifting of the labor-demand curve towards right.
