A simplified economy is specified as follows:

A. Goods market, all values C, I, G and NX values are in billions of C$:

Consumption Expenditure: C = 150 + 0.8(Y-T)Investment Expenditure: I = 1,300 - 420iGovernment Expenditure: G = 340Lump-sum Constant Taxes: T = 340Exports: 90Imports: 10

B. Money market, all M^d values are in billions of C$:

Interest Rate: i = 0.09 or 9%Money Demand: M^d = 780 - 1,900i

Note: Please keep your answers accurate to two decimal places.

a) Given the above information, solve for the following: the equilibrium Y, the money supply M, the consumption expenditure C, and the investment expenditure I.

Y = 0M = 0C = 0I = 0

Now suppose there is an impending federal election, and the government promises to use fiscal policies to stimulate the economy.

b) Find the value of the goods market multiplier.

Goods market multiplier = 0

c) Let G rise to 420. Solve for the new equilibrium Y and C.

Y = 0C = 0

d) Demonstrate how the increase in G affects the economy through the multiplier. Use three rounds of effects to demonstrate the multiplier effects. Let the first round be related to health care spending, the second round related to clothing, and the third round related to food.

Round 1 -> As the government wants to spend $1 (or $1 billion)

on health care, it demands the production of health care equipment

such as hospitals, medicine, equipment, etc. to be built and sold to

the government. So as ΔG = 1, the production ΔY =

0

. This Y is the

income to the nurses, doctors, construction workers, etc.

Round 2 -> As the nurses receive their new income of Y =

0

, theyspend

0

% of this $

0

on clothing ->

0

cents worth of clothing wouldbe produced, or ΔY =

0

-> this

0

cents would be the income of the

workers involved in making the clothing.

Round 3 -> As the clothing workers receive their new income of

Y =

0

, they spend

0

% of this

0

cents on food -> (

0

)(

0

) =

0

or

0

cents worth of food would be produced, or ΔY =

0

-> this would

be the new income to the food workers.

e) Now consider monetary policies only. Suppose the BOC wants to drop the i to 0.04 or 4%, with G still at $340. Solve for the new I and the ΔI compared to when i = 0.09. Given the multiplier, how much would you expect Y to rise by?

I = 0Change in I = 0Change in Y = 0

f) Given the changes in (e), find the equilibrium Y, the money supply M, the consumption expenditure C, and the investment expenditure I.

Y = 0M = 0C = 0I = 0

g) Complete the following statement to demonstrate how the drop in i affects the money supply, then I, then Y, then C.

As i decreases -> ΔM (Select One) -> ΔI (Select One) -> ΔY (Select One) -> ΔC (Select One)

Consider the following growth function for fish given by F( X ) = rX(1 − X/K) where the intrinsic growth rate r = 0.2 and the carrying capacity K = 100 tons of fish. Let the harvest function be given by H = qEX where the catchability coefficient be q = 0.01 and H is harvest in tons of fish.

Compute the following:

a. The maximum yield of fish at the steady state.

b. Effort and Harvest when the price of fish is $1 per ton and the unit cost of effort is $0.5.

c. Determine the supply of fish under Open Access and a Managed Fishery. Consider the price of fish as $0.5, $1 and $2 per ton.

d. Plot these functions on a graph.

using polymorphyism , create an inheritance hierarchy for the following types of insurance :

Home, vehicle , life

2 member functions should be included:

- calcpremium

   - Home- 0.5% of the value of the home

   - Life- 1% of the value of the policy

   - Vehicle - 0.5% of the value of the policy

calcCommission

Home- 0.2% of the value of the home

Life- 1% of the value of the policy

Vehicle - 0.5% of the value of the policy

in main

   1. instantiate an object for each type of insurance policy.

       - Home: value is $457,999.00

       - Life: policy value $1,000,000.00

       - Vehicle: policy value is $25,000.00

   2. Call a global function ( exercising polymorphism) to print out the premium

   and commission for each policy.

   3. make sure that objects of the base class cannot be instantiated.

How much ethanol (d = 0.789 g/mL), in liters, must be dissolved in water to produce 200.0 L of a 1.85 M solution?

Convert the concentration of ethanol in question 3A to ppm. Assume the density of the final solution is 1.00 g / mL. Describe why, or why not, parts per million is a useful unit to use for this particular system.

ACS grade 90. wt% Nitric Acid (d = 1.48g/mL) contains no more than 0.2 ppm Fe. What is the mass of iron in a 2.50 L bottle of nitric acid? If for an experiment you dilute the stock nitric acid above so that the concentration of iron is 4.0 ppb, what is the ratio of acid to total final volume needed?

Air enters a counterflow heat exchanger operating at steady state at 22°C, 0.1 MPa and exits at 7°C. Refrigerant 134a enters at 0.2 MPa, a quality of 0.33, and a mass flow rate of 30 kg/h. Refrigerant exits at 0°C. There is no significant change in pressure for either stream.

Let T₀ = 22°C, p₀ = 0.1 MPa, and ignore the effects of motion and gravity.

You purchase an expensive O2 microelectrode and use it to measure the dissolved O2 profile in a sediment core that you obtained from Long Island Sound. You find that the O2 concentration on the water-sediment interface is 240 mol/L, and it sharply drops to 40 mol/L at 0.2 cm deep in the sediment. If the corresponding dissolved O2 diffusion coefficient (Ds) in porewater seawater is 1.0 × 10-5 cm2 /s. The porosity () of sediment is approximately constant over the sampled interval with  = 0.9. Calculate the diffusive flux of O2 across the sediment – water interface assuming Fick’s First Law of diffusion for porous media in 1-dimension. Make sure that you indicate the sign of the flux (into or out of the sediment).

The working range of the total phenol test is 0-5.00 mg/L. You have at your disposal multiple 500 ± 0.2 mL and 100 ± 0.15 mL volumetric flasks for calibration standard preparation, a 2L Winchester of 99.95% phenol, unlimited distilled/deionized water, and standard 5 ± 0.015, 10 ± 0.025, 25 ± 0.05 mL pipettes:

You are out fishing, when you go to reach for the cooler, when you clumsily knock it into the water. The cooler is in the shape of a cube with a side-length 0.2 meters. The cooler plus sandwiches inside weigh 6 pounds (26.7 N).

a) How deep below the water's surface is the bottom of the cooler, assuming it floats stationary with the top and bottom level with the water's surface?

b) When the cooler was just sitting on the boat, there was actually a buoyant force on it from air. How big is the buoyant force of air on the cooler? How many times smaller is that force than the weight of the cooler? Assume you are at sea level where the density of air is 1.225 kg/m^3
