You own goods A and B. You are considering increasing price of good A by 10%. Here is the information you have
Pa = 20
Qa = 1000
For each $1 increase in Pa, Qa will decrease by 100.
Pb = 12
Qb = 750
For each $1 increase in Pa, Qb will increase by 100.
(The point of this exercise is to have you do everything the long way then use the delta r formula so you can see the difference)

k. Explain why the two methods have different answers.
l. To calculate the change in total revenue from the price change, which method do you prefer? Doing parts a-g or doing part h-j? Briefly explain.
Only h-l

Select a specific real-world firm or market and discuss which model of market structure you think would be most appropriate to describe that market.
(ie. Perfect competition, monopolistic competition, oligopoly, monopoly.)
Real world markets never exactly meet the assumptions of the models, so you can also talk about what aspects of the real-world market may not fit the model what aspects are not well described by the model selected.
You might want to consider, if relevant in your case, factors such as: the nature of the product, factors about the production such as whether or not there are likely to be economies of scale, the number of competitors, the degree of market power, how firms compete, and outcomes such as prices, mark ups, profits and firm entry/exit.

to Italy for use by
an Italian college student.
D. Sale of 1000 shares of IBM stock on the New York Stock Exchange
valued at the
current market price per share.
E. Both B and D.
Which of the following is most likely to decline in a
recession?
A. Nominal GDP
B. Real GDP.
C. Potential real GDP
D. The natural rate of unemployment.
E. All of the above
Nominal GDP this year is $12 trillion. If personal consumption
expenditures are $8
trillion, government purchases are $3 trillion, and gross private
domestic
investment is $2 trillion. Then it follows that
A. net exports are $2 trillion.
B. imports exceed exports by $1 trillion.
C. exports exceed imports by $1 trillion.
D. net exports are zero

reduced if inflation is
greater than anticipated?
A. Borrowers who incurred debts at the beginning of the year at a
nominal interest rate
based on the anticipated rate of inflation.
B. Workers whose wages were set at the beginning of the year based
on the
anticipated rate of inflation.
C. Social Security pension recipients whose pensions are adjusted
each year
according to the actual rate of inflation.
D. Employers who signed contracts granting workers raises for a one
year period at
the beginning of the year based on the anticipated rate of
inflation.

Suppose there are two goods in an economy, X and Y. Prices of these goods are Px and Py, respectively. The income of the only agent (consumer) in the economy is I. Using this information, answer the following questions:
a. Write down the budget constraint of the consumer. Draw it on a graph and label the critical points accordingly. Provide a verbal explanation of why all income is spent, mentioning the underlying assumption for this outcome.
b. Define substitution and income effects.
c. Assuming both goods are normal, suppose Px goes down due to an excess supply of good X, whereas Py is held constant. Drawing a graph, show the substitution and income effects as well as the total effect of this price reduction. Explain the change in demands for the goods using the relation, where MU represents marginal utility. Be precise in labeling your graph and its step-by step explanation.
MUx / Px = MUy / Py
d. Looking at the sign of the total effect, discuss the relation between the price of a normal good and its demand.
e. Now suppose X is an inferior good. How does your answer to part (c) change? Drawing a new graph, comment on the signs of the substitution and income effects.
f. What is Giffen paradox? Drawing a new graph, discuss it in terms of the magnitudes of the substitution and income effects. How is the demand for a Giffen good sloped? Why? Provide the necessary definitions and explain it using the signs and magnitudes of substitution and income effects.

A series of 10 end-of-year deposits is made that begins with $6,500 at the end of year 1 and decreases at the rate of $300 per year with 8% interest.
a. What amount could be withdrawn at t = 10?
b. What uniform annual series of deposits (n = 10) would result in the same accumulated balance at the end of year 10?
I would like to be able to use excel functions to solve this rather than by hand. Thanks!

(a) Outline and explain in detail four types of market failure. What types of problems do market failures give rise to in the economy? Please give an example for each of the market failures you have outlined. Diagrams are not required in this question. 30 marks
(b) Does market failure automatically mean that the government should intervene to deal with the problem? Explain your answer. This question refers to market failure as a whole and not to a particular type of market failure.10 marks

a) Calculate the steady state levels of capital per worker, output per worker and consumption per worker.
b) Now, suppose there is an exogenous change in n, which increases to n=0.055 (while δ, s and the production function remain identical). What are the new steady state levels of capital per worker, output per worker and consumption per worker?
c) Use the Solow diagram to depict the effects of the change in n on steady-state capital per worker
d) After the change in n, is it possible for the economy to go back to the level of steady-state consumption per worker that it had before the change in n by changing its savings rate?

a) Suppose that there is an adverse supply shock that shifts the
short-run supply curve upwards, to P = 3. What are the values of P
and Y in the short-run equilibrium after this shock?
b) What changes (if any) in the values of P and Y would take
place going from the short-run equilibrium of part A to the long
run (assuming no other shocks occur)?
c) If the FED wants to avoid any changes in the level of Y as a response to the supply shock, what should be the change in the quantity of money M?
