10. Consider a two-person, two-commodity, pure-exchange, competitive economy. The consumers' utility functions are U = 911912 + 12q11 + 3q 12 U2 = and %3D = 921922 + 8q21 + 9922 respectively (where q;; denotes the consumption of commodity Q; by consumer i, with i = 1, 2 and j = 1, 2). Consumer 1 has initial endowments of 8 and 30 units of Q, and Q, respectively; consumer 2 has 10 units of each commodity. Determine the excess demand function for the two consumers. Determine an equilibrium price ratio for this economy.

An individual's utility function is given by: U (q1 , q2) = q11/2 . q2 Suppose we know that the individual is maximizing their utility by consuming 9 units of good #1 (q1=9) and six units of good #2 (q2=6). If the current price for good #1 is $1 (p1=1), what must be the price of good #2 (p2) and what must be the individual's current income (y) available to spend on the two goods? a.) p2 = b.) y=
How would you demonstrate part b) diagramatically 6. Assume you can work as many hours you wish at £12 per hour (net of tax). If you do not work, you have no income. You have no ability to borrow or lend, so your consumption, c, is simply equal to your income. a) Derive and plot the feasible set, between daily values of consumption c, and “leisure”, l. Label the values at the intercepts (the points where the feasible frontier cuts the two axes). b) Assume that your optimal choice of consumption and leisure is to work 8 hours per day. Illustrate this choice diagrammatically using the feasible set and indifference curves.
True/False/Uncertain: 1. In taking an exam, Atack, a rational student, allocates his time to the various questions so as to equalize hismarginal point utility per minute on all questions. 2. The marginal utility of food to Zecher depends only on the amount of food (and not on the amount ofhousing) and the marginal utility declines as more food is consumed; likewise for housing. Therefore,both food and housing are normal goods. (Hint: Express the optimality condition for Zecher’s [UMP], MUF/MUH = PF/PH. Notice that PF/PH is fixed. If all of an increase in income is spent on F, can the equality be maintained?)
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 fast

The consumer choice is not restricted to the choice of consumptiongoods. In fact, it can apply to all our decisions that involve trade-offs. Suppose Mary has awage per hour of 10 euros. With her earned income she consumes. That isC=wH per day.She also decides how many hours to work of take leisure time each day.H=24-N, whereHis work and N is leisure. Her utility is given by （picture） Solve for the optimal decision of labor/leisure. Plot the budget constraint and the indif-ferent curve. What is the labor supply function?
Need help on part (d) and (e) 6. Assume you can work as many hours you wish at £12 per hour (net of tax). If you do not work, you have no income. You have no ability to borrow or lend, so your consumption, c, is simply equal to your income. a) Derive and plot the feasible set, between daily values of consumption c, and “leisure”, l. Label the values at the intercepts (the points where the feasible frontier cuts the two axes). b) Assume that your optimal choice of consumption and leisure is to work 8 hours per day. Illustrate this choice diagrammatically using the feasible set and indifference curves. c) Use indifference curves and the feasible set to show why, given the properties of the optimal choice in part b), it is not optimal to work, say, 10, or 6 hours per day. d) Now assume that you receive an income of £140 per week from an unknown benefactor. Show the impact on your feasible set, and show a new optimal choice in which consumption increases but labour supply decreases.…
Consider the production of handmade rugs and assembly robots in India and Canada. Assume that Canada is relatively abundant in capital and that India is relative abundant in labour. Furthermore assume that the production technology for rugs and robots is the same in both countries. Draw production possibilities frontiers for each country keeping the production of rugs in the horizontal axis and the production of robots in the vertical axis. Assuming that consumer preferences are the same in both countries, add indifference curves and relative price lines under autarky. What are the differences in the relative price of rugs between the countries under autarky?

Consider an economy with 100 identical households and 100identical firms. Each household is endowed with one unit of time. Half of the households are endowed with equal shares of firm, while the rest areendowed with no firm shares. A householdís utility is u (x; r) = 2 ln(x*r^2) ,where x is consumption of goods, r = 1- l is leisure time and l is thehouseholdís labour supply. Each firm hires households to produce goodsaccording to technology y = L^1/2, where L denotes the labour input. Goodsprice p, wage rate w, and dividend income are all taken as given. Normalizew = 1. Do the following: (a) Derive the Marshallian demands, x (p, D) andr (p,D), where D is dividend. (b) Derive the firmís input demand functionL (p) and profit function pi(p).

A consumer has utility u(x,y,z)= ln(x) + 2ln(y) + 3ln(z) over the three goods, x,y and z and pZ = 1 . Optimally sheconsumes 30 units of z. What is her income? How much money does she spend on x?(HINT: MUX =??, MUY =??, MUZ =??and remember the “equivalent bang for the buck” condition)(b) Forget about (a). Suppose you have t = 29 hours in total to spend on 3 projects X, Y and Z to make some money.If you spend x hours on project X, you make 2√? dollars;If you spend y hours on project Y, you make ?√? dollars;If you spend z hours on project Z, you make ?√? dollars;Writing down your “utility function” u(x,y,z) and the constraint, solve the utility maximization problem; what isthe optimal amount of time to spend on x ? on y? on z ?
