RESERVE RATIO: The amount of reserves required by the Federal Reserve System as a ratio of the amount deposits backed by the reserves. Modern reserve ratios are in the range of 1-3% for checkable deposits. The reserve ratio plays a key role in the deposit multiplier.

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. Because different investment projects have different returns, businesses often have a range of alternatives projects from which to choose. Combining all projects throughout the economy gives rise to an investment demand curve relating investment expenditures to the interest rate.
