Q81
Which of the following describes the 'Income Effect' for a strictly inferior necessity good when its market price falls?
It reinforces the substitution effect, expanding total quantity demanded
It opposes the substitution effect, reducing the net expansion in quantity demanded
It turns perfectly elastic at the horizontal axis mapping
It drops the marginal utility to absolute infinity instantly
Explanation
When the price of an inferior good falls, the consumer's real income increases. For an inferior good, an increase in real income leads to a decrease in the quantity demanded, meaning the income effect works in the opposite direction of the price drop.
Q82
Under the Cournot Duopoly model, what baseline behavioral assumption does each firm make regarding its competitor's output level when deciding its own profit-maximizing output?
Each firm assumes the rival will keep its price constant
Each firm assumes the rival will keep its output quantity constant
Each firm assumes the rival will copy its pricing strategies exactly
Each firm assumes the rival will exit the market structure completely
Explanation
The fundamental behavioral assumption of the Cournot duopoly model is that each firm treats the output of its rival as a fixed constant when choosing its own quantity to produce.
Q83
Which theorem states that under perfect competition, the presence of an externality can be resolved efficiently through private bargaining without state intervention, provided property rights are clearly defined and transaction costs are zero?
Arrow's Impossibility Theorem
Coase Theorem
Rybczynski Theorem
Stolper-Samuelson Theorem
Explanation
The Coase Theorem, formulated by Ronald Coase, asserts that private bargaining can correct externalities efficiently under zero transaction costs and well-defined property rights, regardless of who holds those rights.
Q84
What analytical curve graphs the various combinations of two goods that a consumer can buy given their total budget expenditures and the relative market prices of those goods?
Indifference map line
Budget constraint line
Production possibility curve
Engel curve trajectory
Explanation
The budget line tracks the absolute financial boundaries of consumer choice, delineating accessible baskets from inaccessible combinations based on prices and nominal income.
Q85
Which macroeconomic function relates the level of planned corporate fixed capital expenditures to the ratio of a firm's stock market value to its replacement cost?
The accelerator principle model
Tobin's q-theory of investment
The Real Balance Effect paradigm
The marginal efficiency of capital multiplier
Explanation
Tobin's q-theory of investment states that if 'q' (market value of installed capital divided by its replacement cost) is greater than 1, firms have a powerful incentive to invest in new capital equipment.
Q86
According to the classical Quantity Theory of Money (Fisher's Equation $MV = PT$), what happens to the general price level ($P$) if the money supply ($M$) doubles, assuming velocity ($V$) and transactions ($T$) are constant?
The price level remains completely flat
The price level doubles exactly
The price level falls by 50% linearly
The price level multiplies by four times
Explanation
In the classical framework, V and T are assumed to be fixed by real supply-side factors in the long run. Therefore, changes in the money supply (M) lead to a direct, exactly proportional change in the price level (P).
Q87
In the IS-LM macroeconomic model, what is the short-run effect of an expansionary fiscal policy (such as a massive increase in government spending) on interest rates and national income?
Interest rates fall while income increases
Both interest rates and national income increase
Interest rates increase while income falls
Both interest rates and national income decrease
Explanation
An expansionary fiscal policy shifts the IS curve to the right. Along an upward-sloping LM curve, this shift results in an increase in both the equilibrium level of interest rates and real national income.
Q88
Which type of financial policy lag represents the time window required for lawmakers to formulate and legally pass a tax amendment after detecting an economic shock?
Outside lag
Implementation / Legislative lag
Recognition lag
Operational response lag
Explanation
The inside lag is divided into recognition lag and implementation (or legislative) lag. The time taken to pass legislation after realizing an economic issue is the implementation lag.
Q89
Which specific economic planning body drafted India's historic Five-Year Plans before being replaced by the NITI Aayog?
National Development Council
Planning Commission
Finance Commission
Central Statistical Organisation
Explanation
The Planning Commission of India, established in March 1950, was the central institution responsible for drafting Five-Year Plans. It was dissolved and replaced by NITI Aayog on January 1, 2015.
Q90
The famous 'Mahalanobis Model' formed the core theoretical architecture of which specific Five-Year Plan in India?
First Five-Year Plan
Second Five-Year Plan
Third Five-Year Plan
Fifth Five-Year Plan
Explanation
The Second Five-Year Plan (1956–1961) was based on the Mahalanobis model, which emphasized rapid industrialization with a heavy focus on basic and heavy capital-goods industries.
