Question:
In the context of a perfectly competitive market, identify the statement that is NOT CORRECT.
In the context of a perfectly competitive market, identify the statement that is NOT CORRECT.
Show Hint
In a perfectly competitive market, the equilibrium is achieved when the price equals marginal cost, and the output is socially optimal. Any deviation from this results in welfare loss.
Updated On: Apr 20, 2025
- Producing less than the competitive output lowers welfare.
- Producing more than the competitive output lowers welfare.
- The welfare is dependent on both price and the competitive output.
- If a consumer values the last unit more than its marginal cost of production, producing an additional unit shall lower welfare.

The Correct Option is D
Solution and Explanation
Step 1: Understanding perfectly competitive market characteristics.
In a perfectly competitive market, the price is equal to the marginal cost at the competitive output level.
Producing less than the competitive output results in underproduction, which lowers welfare (Option A).
Producing more than the competitive output leads to overproduction, causing inefficiency and a reduction in welfare (Option B).
Welfare in a competitive market is dependent on both price and competitive output levels (Option C).
Step 2: Analyze Option D.
If a consumer values the last unit more than its marginal cost, producing that additional unit increases welfare. Therefore, producing more when the consumer values the last unit more than the marginal cost will not lower welfare.

- Consider a two good economy where a denotes consumption of apricots and b denotes consumption of bananas. Anu's utility function is UAnu (a, b) = a + 2b, and Binu's utility function is UBinu (a, b) = min{a, 2b}. Anu initially has no apricots and 12 bananas. Binu initially has 12 apricots and no bananas. In the competitive equilibrium, which one of the following will be Anu's optimal consumption bundle ?
- The demand function is given as \( \log Q = \log A + 0.5 \log P \), where \( Q \) is quantity, \( P \) is the unit price of the good and \( A \) is a positive real number. The own price elasticity of demand is:
- A Constant Elasticity of Substitution (CES) utility function is given as: \[ U_{{CES}}(z_1, z_2) = \frac{1}{\delta} \left( z_1^\delta + z_2^\delta \right) \] where \( z_1 \) and \( z_2 \) are two goods, and \( \delta \leq 1, \delta \neq 0 \). A Quasi-linear (QL) utility function is given as: \[ U_{{QL}}(z_1, z_2) = 2z_1 + \log z_2 \] where \( z_1 \) and \( z_2 \) are two goods. Which of the following statements is/are NOT CORRECT?

- Amma's tone in the context of the given passage is that of :
For Amma, the difference between men and women was a kind of discrimination and inequality; she felt strongly about women's rights but was not familiar with concepts like gender and patriarchy. She would have dismissed Betty Friedan because she was predominantly dealing with the problems of white middle-class women in the United States. Amma, and women of her generation, could de-link the oppression of women from the wider struggle for the liberation of human beings from class exploitation and imperialism. So Amma continued to play her role as mother and wife, but would often complain: 'I am a doormat on which everyone wipes their emotional dirt off". - Fill in the blanks by choosing the correct sequence for the following passage:
I am wearing for the first time some (i)_____ that I have never been able to wear for long at a time, as they are horribly tight. I usually put them on just before giving a lecture. The painful pressure they exert on my feet goads my oratorical capacities to their utmost. This sharp and overwhelming pain makes me sing like a nightingale or like one of those Neapolitan singers who also wear (ii)_______ that are too tight. The visceral physical longing, the overwhelming torture provoked by my (iii)_______ forces me to extract from words distilled and sublime truths, generalized by the supreme inquisition of the pain my (iv)_______ suffer. - The appropriate synonym for the word ‘ignite' in the following passage will be :
Spirituality must be integrated with education. Self-realization is the focus. Each one of us must become aware of our higher self. We are links of a great past to a grand future. We should ignite our dormant inner energy and let it guide our lives. The radiance of such minds embarked on constructive endeavor will bring peace, prosperity and bliss to this nation. - Which of the following sentences is punctuated correctly ?
