Introduction Investment decisions often involve uncertainty. In such situations, investors rely on tools like expected value and variance to evaluate potential outcomes and associated risks. The expected value gives a measure of the average return one can anticipate, while the variance tells us how much the returns fluctuate around the average. In this answer, we […]

From the following pay-off matrix, where the payoffs (the negative values) are the years of possible imprisonment for individuals A and B, determine: (i) The optimal strategy for each individual. (ii) Do individuals A and B face a prisoner’s dilemma?

Introduction The Prisoner’s Dilemma is one of the most famous examples in game theory that demonstrates how two individuals may not cooperate, even if it is in their best interest to do so. In this question, we are given a payoff matrix with the number of years in prison that individuals A and B might

Introduction Game theory is a fundamental concept in economics and social sciences that studies the strategic interactions among decision-makers, also known as players. These players make decisions based on the anticipated actions and responses of other players. A critical classification in game theory is between games of complete information and games of incomplete information. Understanding

What are the two principles of justice as mentioned by the philosopher Rawls?

Leave a Comment / MEC-101 /

Introduction John Rawls was a prominent 20th-century philosopher best known for his work on political philosophy and moral theory. In his influential book “A Theory of Justice,” Rawls proposed a new way to think about justice in society. He introduced the concept of “Justice as Fairness” and developed two core principles of justice that aim

Consider a Cobb-Douglas utility function U (X, Y) = Xα Y (1- α), Where X and y are the two goods that a consumer consumes at per unit prices of Px and Py respectively. Assuming the income of the consumer to be ₹M, determine: a. Marshallian demand function for goods X and Y. b. Indirect utility function for such a consumer. c. The maximum utility attained by the consumer where α =1/2, Px =₹ 2, Py = ₹ 8 and M= ₹ 4000. d. Derive Roy’s identity.

Introduction The Cobb-Douglas utility function is one of the most widely used utility functions in microeconomics. It models consumer preferences where two goods are consumed in fixed proportions. This problem involves the derivation of the Marshallian demand, indirect utility, and application of specific values to determine maximum utility. We also derive Roy’s identity, which helps

Define the term ‘Shepard’s lemma’. Assume that the production function of a producer is given by Q=5L0.5 K0.3, where Q,L and K denote output, labour and capital respectively. If labour cost ₹ 1 per unit and capital ₹2, find the least cost combination of inputs (L&K)

Introduction In microeconomics, cost minimization is an essential concept where a firm aims to produce a given level of output at the lowest possible cost. Shepard’s Lemma is a theoretical tool that helps in deriving input demand functions from the cost function. In this answer, we will define Shepard’s Lemma and apply it to the

The production function of a small factory that produces and sells toys is: Q = 5√(L.K). Suppose 9 labour hours and 9 machine hours are used every day, what is the maximum number of toys that can be produced in a day? Calculate the marginal product of labour when 9 labour hours are used each day together with 9 machine hours. Suppose the firm doubles both the amount of labour and machine hours used per day. Calculate the increase in output. Comment on the returns to scale in the operation.

Introduction In economics, a production function is a mathematical relationship that shows how inputs like labour and capital are used to produce output. The given production function helps us understand how a factory that manufactures toys can utilize its resources efficiently to maximize output. This question includes both numerical computation and a discussion on the
