1. Explain and show how the full Keynesian sticky wage model is built. What are the main relationships? Explain briefly what each curve depicts.

2. Imagine that the economy starts off in a situation where the labor market clears. The economy is hit by a shock that reduces consumption demand temporarily. (See e.g. Figure 3.) Show the effects of the shock using graphs. Explain every shift of a curve. What are the effects on the interest rate, consumption, investment, output, the price level, the real wage and employment?

3. Do these effects fit the business cycle facts?

4. What would happen if the nominal wage adjusted in response to the shock? (Assume for this that wage adjustment is faster than the return of consumption demand to its initial level, i.e. maintain consumption demand at its low level induced by the shock here).

5. Using graphs, illustrate how fiscal policy could be used to counteract the effect of the shock. (Assume that the nominal wage remains at its initial level.)

6. Show, using graphs, the effects of the same shock in an economy where the nominal wage is flexible. How do the interest rate, output, the price level, the real wage and employment change?

7. How do these changes compare to those in a) the short run and b) the long run of the Keynesian model?

ACME Incorporated has built a factory 1 kilometer upwind of your home. It is a coal power plant that emits carbon monoxide (CO) at a rate of 500 kilograms per second.

Discussion Question 1

What will the concentration of CO be outside your home be if the factory emits CO at the rate given above, your home is 1 km downwind of the factory, the wind speed is 3 meters per second, and the atmospheric stability is slightly stable? Report in units of kg/ m³. To calculate this concentration, use the simplified Gaussian Plume Equation:

C= QU    ×   12πσyσz

Where:

• C is concentration (mg/m³)
• Q is emission rate (kg/second)
• U is wind speed (m/s)
• p is a constant = 3.14159
• s_y is the horizontal dispersion coefficient (m)
• s_z is the vertical dispersion coefficient (m)

We can estimate s_y and s_z as:

s_y = ax^0.893                     s_z = cx^d – f

Where:

• x is the distance downwind (m)
• a, c, d, and f are dependent on atmospheric stability and are given in the table below

Discussion Question 2

Does this concentration violate the 8-hour NAAQS standard for CO (9 ppm)? Note that you need to convert units from kg/m³ to ppm to answer this.

***Hints***

1 kg = 1000 g

The molar mass of CO is 22.01 g/mol

Avogadro’s number is 6.02*10²³ molecules/mol

Assuming standard conditions of T=298 Kelvins and P = 1 atm, there are 2.46 *10²² molecules/L of air

1000L = 1 m³

To get units in ppm, do: (# of molecules of CO)/(# of molecules of air) *10⁶

1. In an L.A. Law episode, an automobile manufacturer knowingly built cars that had a significant safety flaw. Rather than redesigning the cars (at substantial additional cost), the manufacturer calculated the expected costs of future lawsuits and determined that it would be cheaper to sell an unsafe car and defend itself against lawsuits than to redesign the car. What issues does the financial analysis overlook? What is the consequence of not redesigning the car?

11. Suppose that a 32M × 16 memory built using 512K × 8 RAM chips and memory is word-addressable.

a) How many RAM chips are necessary?  

b) If we were accessing one full word, how many chips would be involved?

c) How many address bits are needed for each RAM chip?

d) How many banks will this memory have?

e) How many address bits are needed for all of memory?

f) If high-order interleaving is used, where would address 14 (which is E in hex) be located?

g) Repeat Exercise 11f for low-order interleaving.

Encrypt the given plaintext with the key. Built the key matrix (big size). And show how you get each letter ciphertext (you can do that by making shapes and arrows in key matrix).

No need to draw key matric again and again.   

Show all your work. If you just write cipher text and key matric without showing (shapes and arrow on key matrix) that how you get the ciphertext then your marks will be deducted.

key :  alphabets

plaintext :   smartness

You have just taken a job as a consultant for a custom-built motorcycle company. The plant manager says he had read that a synchronized push supply chain strategy was associated with stable demand, and one of the goals for his company was to remove as much demand variability as possible. He recommends using a synchronized push strategy for their customized product. How would you reply to him?

• Consider a simple application-level protocol built on top of UDP that allows a client to retrieve a file from a remote server residing at a well-known address. The client first sends a request with a file name, and the server responds with a sequence of data packets containing different parts of the requested file. To ensure reliability and sequenced delivery, client and server use a stop-and-wait protocol. Ignoring the obvious performance issue, do you see a problem with this protocol? Think carefully about the possibility of processes crashing.

without using the table of Tolerance factors for normal distributions, find a tolerance interval that gives two sided 95% bounds on 90% of the distribution of packages of 95% lean beef. Assume the data came from an approximately normal distribution. where n=30, sample mean=96.2%, and standard deviation= 0.8%.

Consider a market with two goods, x and z that has the following utility function U = x^0.2z^0.8

a) What is the marginal rate of substitution?

b) As a function of the price of good x (px), the price of good z (pz) and the income level (Y ), derive the demand functions for goods x and z.
