Suppose that the country of Libraria made a concerted effort to increase the educational level of its people. If this effort had no effect on the wages of its workers, one might consider this as evidence in support of a. the human-capital view of education. b. the signaling view of education. c. both the human-capital and the signaling view of education. d. neither the human-capital nor the signaling view of education.

If this effort had no effect on the wages of its workers, one might consider this as evidence in support of:

d. neither the human-capital nor the signaling view of education.

Explanation:

The human capital view of education argues that education increases workers' productivity, which also affects some increase in workers' wages.  The signaling view states that education passes a message about workers' various innate abilities to potential employers. This implies that the focus of the signaling view or theory is not the effect of education on the students but the message communicated in the labor market.
