MARGINAL EFFICIENCY OF INVESTMENT: The anticipated rate of return on a capital investment project undertaken by a business firm. Businesses typically compare the marginal efficiency of investment, abbreviated MEI, on physical capital with interest rate returns on financial capital when deciding to undertake an investment project.
