Name: SANJEEV MISHRA Mobile No: 7050420608 (1) Explain the concept of consumer equilibrium under risk and uncertainty. How does Expected Utility Theory differ from Prospect theory? Ans -> Consumer equilibrium under risk and uncertainty occurs when a person maximizes their expected utility rather than just expected monetary value. Conditions [ U(E(W)) = E(U(W)) ] Curve [Graph 1: Risk lover] u(w) u(b) u(a) a b Risk lover U(E(W)) < E(U(W)) [Graph 2: Risk neutral] u(w) u(b) u(a) a b w Risk neutral U(E(W)) = E(U(W)) [Graph 3: Risk averter] u(y) u(b) u(a) a b w Risk averter U(E(W)) > E(U(W)) (2) Discuss the role of technical progress in shifting the production function. Distinguish between Hicks-neutral, Harrod-neutral, and Solow-neutral technical progress with suitable diagrams.

Distinguish between Hicks-neutral, Harrod-neutral, and Solow-neutral technical progress with suitable diagrams.

Ans -> Technological progress is a phenomenon which decreases the amounts of labor and capital needed in production process. [Technological progress] (1) Neutral Technological progress (2) Labor saving Technological progress (3) Capital saving Technological progress Neutral Technical progress K A P = A f(K, L) L Labour Saving Technological progress K A P = f(K, AL) L Capital Saving Technological progress K P = f(AK, L) L Hicks neutral (1) Both labour and capital equally (2) Y = A f(K, L) Harrod neutral (1) Labour augmenting only (2) Y = f(K, AL) Solow neutral (1) Capital augmenting only (2) Y = f(AK, L) (3) Why is Arrow's impossibility theorem considered a challenge to social welfare maximization? Explain its policy implication. Ans. K. J. Arrow in his Social Choice and Individual Values has demonstrated the impossibility of obtaining the social welfare function even if individual preferences are consistent. He suggests five minimum conditions or criteria which social choices must satisfy in order to reflect preferences of individuals. They are as follows: (i) Collective Rationality (ii) Responsiveness to individuals preferences (iii) Non-imposition (iv) Non-dictatorship (v) Independence of Irrelevant Alternatives Challenge to social welfare function Arrow shows that the use of democratic process of voting leads to contradictory welfare criterion. This 'voting paradox' explored by Prof. Arrow, comes as a shock to one's faith in electoral democracy, according to Prof. Musgrave. Critically distinguish between the classical quantity theory of money and Friedman's modern quantity theory.

How does it differ from the traditional balanced budget approach? Functional Finance is coined by Abba P. Lerner. based on effective demand principles and chartalism. According to him government should finance itself to meet explicit goals. such as controlling the business cycle, achieving full employment, ensuring growth, and low inflation. Function of government (i) the government shall always maintain a reasonable level of demand (ii) Borrowing money when it wishes to raise the rate of interest and by lending money or repaying debt when it wishes to lower the rate of interest. (iii) If either of the first two rules conflicts with principles of 'sound finance' or of balancing the budget, or of limiting the national debt, so much the worse for these principal. The government shall print any money that may be needed to carry out rules 1 and 2. Q6 Differentiate between trade creation and trade diversion. Explain their welfare implications in the context of customs unions. Ans -> Aspect | Trade creation | Trade diversion --- | --- | --- (i) Meaning | shift production from high-cost domestic markets to low-cost partner makers | shifts imports from low-cost non-member to higher-cost partner ii) Source of goods: Moves from local production to a partner country. Moves from a non-member country to a partner country. iii) Tariff Impact: Tariff drop for the partner, removing local market distortions. Tariffs stay high for outsiders, creating preferential gaps. iv) Economic welfare: Always increases national and global welfare. Often reduces national and global welfare.

Model [A graph showing Marginal Product of Labour (MPL) curves shifting outward as capital accumulates, with a horizontal wage line 'w' and labour supply increasing from N1 to N2 to N3.] Movement of labour - When the capitalist sector expands it extracts or draws labour from the subsistence sector. - This causes the output per head of labourers who move from the subsistence sector to the capitalist sector to increase. - Since Lewis in his model considers overpopulated labour surplus economies he assumed that the supply of unskilled labour.

8) Explain the objectives and significance of Inflation Targeting under India's Monetary Policy Framework. Ans -> Inflation Targeting in India is a monetary policy framework where the Reserve Bank of India uses interest rates to keep consumer price index inflation at a target of 4% with a tolerance range of plus or minus 2% (2% to 6%).

Why are they important in empirical economic research? Ans -> Type I error occurs when the null hypothesis ($H_0$) is true, but our test rejects it. The rate of the type I error is called the size of the test and denoted by the greek letter $\alpha$. It usually equals the significance level of a test. Type II error occurs when the null hypothesis is false, but erroneously fails to be rejected. | | Null hypothesis ($H_0$) is true | Null hypothesis ($H_0$) is false | | :--- | :--- | :--- | | Reject null hypothesis | Type I error False positive | Correct outcome True positive | | Fail to reject null hypothesis | Correct outcome True negative | Type II error False negative | (10) Explain the economic significance of Lagrange Multiplier method in constrained optimization problems.

Lagrange Multiplier is a mathematical technique to optimize a function with constraints. General Formula objective: Maximize or Minimize f(x,y) Constraint: g(x,y) = c => c - g(x,y) = 0 Lagrangian L(x,y,λ) : f(x,y) + λ(c - g(x,y)) Solve: ∂L/∂x = 0, ∂L/∂y = 0, ∂L/∂λ = 0 Significance Used in shadow pricing Computing optimization subject to constraints Long Ans (11) Critically examine the relevance of General Equilibrium Analysis in Modern Market economies.
