@Rob
For constraints you have demand function for both student and non-student and an additional capacity constraint. You have to carry out optimization such that MR for each market is equal to MC. Also, you can substitute q1 = 150 - q2, and be able to get profits in terms of q2. Through usual first order conditions you can solve for q2 that maximizes profit, and then you will be able to calculate both p1 and p2, all subjected to the capacity constraint. |

I got no. of firms = 18. Each producing 5 units of output. I used the fact that when patent expires, firm's monopoly disappears and new firms will enter the market driving the profits to zero.

Put MC = price and profits = 0, you will get two equations in two unknown.

You are optimizing for a firm, therefore, for MC, 'n' wouldn't enter the equation. Only in inverse demand function while calculating price you will consider output of the industry. Also, while calculating profits, it should be (100-nq)q, and similarly in other expressions.

hav u solvd this? if yess plz share ur solution
Consider an economy where the agents live for only two periods and where there is only one good. The life-time utility of an agent is given by U = u(c) + v(d), where u and v are the first and second period utilities, c and d are the first and second period consumptions and is the discount factor. lies between 0 and 1. Assume that both u and v are strictly increasing and concave functions. In the first period, income is w and in the second period, income is zero. The interest rate on savings carried from period 1 to period 2 is r. There is a government that taxes first period income. A proportion of income is taken away by the government as taxes. This is then returned in the second period to the agent as a lump sum transfer T. The government’s budget is balanced i.e., T = w. Set up the agent’s optimization problem and write the first order condition assuming an interior solution. For given values of r, , w, show that increasing T will reduce consumer utility if the interest rate is strictly positive. |

Hi ,
Answer to the second ques woud be a=b=10 , as these are satiation preferences. Also intuitively utitlity will be 0 at this point and everywhere else it will be negative. Answer to its second part will be the same, bcoz these are satiated preferences. Please correct me if I am wrong |

Can't be the same since the consumer can't afford this bundle with an income of 10 units

Hey Dhruv,
In ques 6, When the govt is providing 1 to 1 subsidy, it means the slope of the budget line will halve and in the second case it will be shifted outward by 250. N if we draw the we will notice that all the consumption bundle when 1 to 1 subsidy is provided lied under the new budget line. which means the second policy is better. |

Lal family's budget constraint will be,
C + H = M where, H is housing expenditure, C is other expenditure and M is income. If government provides one-to-one subsidy on housing expenditure, that implies C + H = M + H Hence, C = M For, new policy their budget constraint will be, C + H = M + 250 |
