A model without any simplifying assumptions:

1 answer:

4 0

The answer is C.: Is highly complex and likely unworkable
The simplifying assumption is a method that helps us to understand a certain complex system on a much more simpler point of view.
The purpose of creating a model is to make a smaller prototype of an actual system, not the ystem itself. (for example, in a model of Galaxy, it won't include the complex gravitational pulling between the planets)

Why didn’t worldcom try to structure the transactions to get a “step-up” in the tax bases of mci’s assets(?

Alex Ar [27]

I believe that the answer to the question provided above is worldcom try to structure the transactions to get a “step-up” in the tax bases of mci’s assets because he doesn't have enough influence to do so.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.

Trade will take place: A. if the maximum that a consumer is willing and able to pay is less than the minimum price the producer

Lubov Fominskaja [6]

Answer: (B.) If the maximum that a consumer is willing and able to pay is greater than the minimum price the producer is willing and able to accept for a good.

Explanation:

A producer will only sell goods and services if the consumer is willing to pay as much as the asking price. i.e. The price that the producer is asking. For this to happen the consumer's willingness to pay must be greater than the minimum price.

Therefore , the trade will take place if the maximum that a consumer is willing and able to pay is greater than the minimum price the producer is willing and able to accept for a good.

Asset A and B have expected returns of 5% and 3% per year respectively. Their annual volatilities are both 20% and the correlati

Novay_Z [31]

Answer:

1. Weight of A=0.5, Weight of B= 0.5

2. Asset A has the highest shape ratio. The weight of A and B in the optimal risky portfolio that has the highest shape ratio is:

Weight of A= 0.105, Weight of B= 0.895

Explanation:

Expected return of Asset A= 5%Expected return of Asset A= 5%

Expected return of Asset B= 3%

Annual volatilities of Asset A= 20%

Annual votalities of Asset B= 20%

1. Correlation coefficient = 30% = 0.3 < 1

Risk Free Rate = 1% =0.01

1. Weight of A and B in portfolio with minimal risk is:

Weight of A= β^2B - Cov (XAXB) /β^2A + β^2B - 2Cov (XAXB)

Therefore,

CovXAXB = PAB (Volatility of A) (Volatility of B)

= 0.3 × 0.2 × 0.2

= 0.012

Hence,

Weight of A= (0.2)^2 - 0.012 / (0.2)^2 + (0.2)^2 - 2(0.012)

Weight of A= 0.04 - 0.012 / 0.04 + 0.04 - 0.024

= 0.028/ 0.08 - 0.024

= 0.028/ 0.056

=0.5

Weight of A = 0.5

Weight of B= 1 - Weight of A

Weight of B= 1 - 0.5

Weight of B= 0.5

2. Shape ratio of A= RA - Rf / β

= 0.05 - 0.01 / 2

= 0.04/2

= 0.02 =20%

Shape ratio of B= RB - Rf / β

= 0.03 - 0.01/ 2

0.02 / 2

=0.01 = 10%

So, Asset A has the highest shape ratio

Cov (XAXB) = PAB (Volatility of A) (Volatility of B)

= 0.03 × 0.2 × 0.1

= 0.006

Weight of A= β^2B - Cov (XAXB) /β^2A + β^2B - 2Cov (XAXB)

Weight of A = (0.1)^2 - 0.006 / (0.2)^2 + (0.1)^2 - 2(0.006)

= 0.01 - 0.006 / 0.04 +0.01 - 0.012

= 0.004/ 0.05 - 0.012

= 0.004/ 0.038

= 0.105

Weight of A = 0.105

Weight of B= 1 - 0.105

Weight of B= 0.895

Trout farming is a perfectly competitive industry and all trout farms have the same cost curves.

Diano4ka-milaya [45]

Answer:

(i) The farm can cover its revenue using its total variable cost, therefore the farm will continue producing 200 units

(ii) The farm cannot cover its revenue using its total variable cost, therefore the farm will shut down

(iii) The two relevant points on supply curve will be: (Price = $12 & Quantity = 0) and (Price = $25 & Quantity = 200)

Explanation:

(i)According to given data, When output is 200 but price is $20, this price is equal to ATC, so the farm breaks even. But since this price is higher than AVC of $15, the farm can cover its revenue using its total variable cost, therefore the farm will continue producing 200 units.

(ii) When output is 200 but price is $12, this price is equal to ATC, so the farm makes economic loss. Also, this price is lower than AVC of $15, so the farm cannot cover its revenue using its total variable cost, therefore the farm will shut down.

(iii) The farm's supply curve is the portion of its Marginal cost (MC) curve above the minimum point of AVC. Since price equals MC, the two relevant points on supply curve will be: (Price = $12 & Quantity = 0) and (Price = $25 & Quantity = 200).
