Macroeconomics and Policy

Real national income measures the actual output of goods and services produced in an economy, adjusted for inflation. For real national income to increase, there must be an increase in the actual physical production of goods and services. Option D correctly identifies this. Increased savings (A) could indicate reduced consumption but not necessarily higher output. Higher prices (B) might increase nominal GDP but not real output. Increased money supply (C) primarily affects nominal variables (inflation) rather than real production.

Deficit financing increases money supply without matching goods production, leading to inflation (rising prices). More money chases the same amount of goods. Options B, C, and D are incorrect - deficit financing doesn't make markets more competitive, control prices, or necessarily increase supply.

The Marshall-Lerner condition states that devaluation will improve the balance of payments only if the sum of the price elasticities of demand for exports and imports is greater than one. If this sum is less than or equal to one, devaluation worsens the BOP or has no effect. This is because devaluation makes exports cheaper and imports dearer, improving the trade balance only if quantity responses are sufficiently strong.

Monetary measures to correct balance of payment imbalances typically include deflation, exchange control, and devaluation, which directly influence money supply or exchange rates. Restrictions on exports are classified as trade or direct controls rather than monetary measures.

Devaluation improves trade balance only when export demand is elastic (Marshall-Lerner condition). If demand is inelastic, devaluation may worsen the trade balance by increasing import costs without sufficiently increasing export volumes.

Cheap money refers to a situation where interest rates are low, making borrowing affordable for businesses and individuals. When central banks keep rates low, it's called 'cheap money' policy. Options B, C, and D refer to economic indicators (savings, income, standard of living) that are unrelated to the cost of borrowing money.

When too much money is chasing too few goods, it creates demand-pull inflation, where prices rise because demand exceeds supply. This is a classic definition of inflation in economic terms. Deflation is the opposite, recession is economic decline, and stagflation combines inflation with stagnation.

Interest Rate Policy is a key instrument of Monetary Policy, which is implemented by the Reserve Bank of India. Monetary Policy controls money supply and interest rates to achieve economic objectives like price stability and growth.

Deflation is a decline in the general price level, typically caused by a contraction in money supply or available credit. Option B correctly defines both the cause (monetary contraction) and effect (price decline), while option D only states the effect without explaining the economic mechanism.

Disinflation refers to the process of reducing inflation through deliberate monetary policy measures, primarily by decreasing money supply. Demand-pull and cost-push are types of inflation, not cures. Reflation is the opposite - increasing money supply to combat deflation.

A closed economy is one that has no interaction with the rest of the world - meaning neither exports nor imports take place. All economic activity is contained within the country's borders.

Stagflation is an economic condition characterized by slow economic growth (stagnation), high unemployment, and rising prices (inflation) occurring simultaneously. This is unusual because inflation typically accompanies growth, not recession. The term emerged in the 1970s when many economies faced this problematic combination of stagnant growth with persistent inflation.

SLR (Statutory Liquidity Ratio) is a monetary policy tool used by central banks. Increasing SLR forces banks to hold more liquid assets (like gold and government securities) rather than lending them out, thereby mopping up excess money supply from the economy. This is a selective credit control measure to control inflation.
