Answer:
If the TRS (marginal rate of technical substitution) is equal to -2 at a given input bundle, then we can conclude that capital is more productive than labor. This is because the negative value of TRS implies that the marginal product of labor is diminishing relative to the marginal product of capital. Therefore, it would be more efficient to decrease the amount of labor and increase the amount of capital in the production process, which would increase the overall output.
