According to the statutory liquidity requirement, banks are required to maintain a certain fi xed proportion of their liabilities in the form of designated liquid assets.
Required reserves are cash balances which the central bank holds to meet its statutory reserve requirements.
Th e two categories of instruments of monetary policy at the disposal of the central bank are the quantitative or general measures and the qualitative or selective measures.
Monetary policy is an operation by the monetary authorities of the country.

According to the Marshall–Lerner condition, for a devaluation to have a positive eff ect on a country’s balance of payments, the sum of the absolute values of the elasticity of demand for its exports and imports should be greater than one.
Structural disequilibrium occurs due to business cycles.
To determine whether the balance of payments is in equilibrium or disequilibrium, only the accommodating transactions are considered.

What are business cycles?
Stabilization policies are also called counter-cyclical policies.
According to the pure monetary theory, the diff erent phases of a business cycle can be explained in terms of the interaction between the accelerator and the multiplier.
During the phase of prosperity, the economy is in a phase of expansion with an increase in the economic activity.
Business cycles relate to economic changes in the long run in production.
Th e neo-classical growth theory was presented by two famous economists, Sir Roy Harrod of the UK and Evesey Domar of the USA in the late 1930s.

Th e MEC schedule represents the true investment demand schedule for the economy as a whole.
For every fi rm, the MEC schedule is a stair-like curve while the aggregate MEC schedule is a downward sloping curve.
Th e supply price of a capital asset is the cost of replacing the capital asset, which is under consideration, with an old one.
Th e present value of a capital asset is the sum obtained aft er discounting the expected future yields over its entire life at the market rate of interest.
Investment which changes due to a change in income and the interest rate is called the autonomous investment.

Show as to how the imposition of a tax, given the level of government expenditure, causes a reduction in the equilibrium level of income in a three-sector economy?
While exports must be added to the total fi nal expenditures, imports must be deducted from the total fi nal expenditures to arrive at the aggregate demand.
When exports are greater than imports, there exists a net import balance or an unfavourable balance of trade.
