Question

State your views on profit theory of investment.

Answer 1

The profit theory of investment suggests that investment decisions are primarily influenced by the expected profits from the investment. According to this theory, entrepreneurs invest when they anticipate a positive profit, implying that investment is guided by the expectation of future returns. This view highlights the role of profit expectations and marginal efficiency of capital (MEC) as key determinants. MEC, defined as the expected rate of profit from an investment, is compared with the rate of interest to decide the level of investment. If the MEC exceeds the rate of interest, investment is encouraged; if it is lower, investment declines. This theory underscores the psychological and anticipative nature of investment decisions, emphasizing that investment is driven more by profit outlook than by mechanical factors like interest rates alone. Thus, profit expectations guide the volume and timing of investment, making profit a central motivator in investment theory.
