Specifically, suppose that ₁ falls from 5 to 1 for firms and from 5 to 0 for households. Solve for the equilibrium levels of investment, consumption, the trade balance, the current account, and the country's net asset position in period 1, and output and profits in period 2. Provide intuition.

- Consider a one good, two-period closed economy without government. The representative agent is endowed with ?1 in the first period and ?2 in the second period. (Q) Derive the optimal consumption and investment plans for the representative consumer and representative firm respectively.Consider a one period model in which a representative agent maximises the utility function: u(c,l) = lnc + 5lnl subject to the budget constraints: c = (1-t)w(1-l) + v where c is consumption and l is the amount of leisure, they enjoy out of a total of one unit of time available, t is the tax on wage earnings which pays for v in government transfer payments. A. Solve for first order conditions of the representative agent. B. Write down the market clearing condition (resource constraint) for the aggregate economy. C. Solve for equilibrium consumption and labour choices.Consider a one period model in which a representative agent maximises the utility function: u(c,l) = lnc + 5lnl subject to the budget constraints: c = (1-t)w(1-l) + v where c is consumption and l is the amount of leisure, they enjoy out of a total of one unit of time available, t is the tax on wage earnings which pays for v in government transfer payments. A. Derive the equation that determines how much revenue the government will receive for a given rate of tax t. What is this relationship called? B. Solve for the maximum amount of revenue the government can raise from this tax. Hint: the tax rate will be a fraction between 0 and 1. C. In this particular example, what are the contributions of the income and substitution effects?
- Anna and Bob are the only residents of a small town. The town currently funds its fire department solely from the individual contributions of these two residents. Each of the two residents has a utility function over private goods x and total number of firemen M, of the form: u(x,M)=2 ln x+ln M?. The total provision of firemen hired, M, is the sum of the number hired by each of the two persons: M=M^A+M^B. Ann and Bob both have income of 200 each, and the price of both the private good and a fireman is 1. They are limited to providing between 0 and 200 firemen. For the purposes of this problem, you can treat the number of firemen as a continuous variable (it could be man-years). Suppose that the government recruits additional ? firemen and taxes Ann and Bob equally to cover the cost. Therefore, the total number of firemen is M^A+M^B+N, where M^A, M^B are appropriate individually-optimal contributions of A and B (i.e., the agents behave optimally, conditional on the policy), and each…Now,suppose N=3 with a market clearing interest rate. The first two agents are the same as earlier. The third agent has an endowment of 20 in the first period and consumes 15 in the second period. If the first two agents each consumed 21 units in the first period, how much did the third agent consume in the first period? Plz do fastFor a certain company, the cost function for producing x items is C(x)=40x+150 and the revenue function for selling x items is R(x)=−0.5(x−90)^2+4,050. The maximum capacity of the company is 130 items. The profit function P(x) is the revenue function R(x) (how much it takes in) minus the cost function C(x) (how much it spends). In economic models, one typically assumes that a company wants to maximize its profit, or at least make a profit! 1. Assuming that the company sells all that it produces, what is the profit function? P(x)= 2. What is the domain of P(x)? 3. The company can choose to produce either 50 or 60 items. What is their profit for each case, and which level of production should they choose? 4. Can you explain, from our model, why the company makes less profit when producing 10 more units?
- Anna and Bob are the only residents of a small town. The town currently funds its fire department solely from the individual contributions of these two residents. Each of the two residents has a utility function over private goods x and total number of firemen M, of the form: u(x,M)=2lnx+lnM. The total provision of firemen hired, M, is the sum of the number hired by each of the two persons: M=MA+MB. Ann and Bob both have income of 200 each, and the price of both the private good and a fireman is 1. They are limited to providing between 0 and 200 firemen. For the purposes of this problem, you can treat the number of firemen as a continuous variable (it could be man-years). Consider the setup from above. Suppose that the government recruits additional ?N firemen and taxes Ann and Bob equally to cover the cost. Therefore, the total number of firemen is MA+MB+N, where MA,MB are appropriate individually-optimal contributions of A and B(i.e., the agents behave optimally, conditional on the…Anna and Bob are the only residents of a small town.

For the purposes of this problem, you can treat the number of firemen as a continuous variable (it could be man-years). Consider the setup from above. The government proposes an alternative, market-based solution. They charge each citizen the price p for every firemen stationed at the local fire station. Then, the price is being set at a level p∗ at which each individual demands the socially optimal number of firemen. What is the…Anna and Bob are the only residents of a small town.
