1. Profit-maximizing price for the newspaper is (500 + √(250000 - 20000S)) / 2.

2. Approximately 2,907 copies will be sold at the profit-maximizing price when S = 100.

We need to find the price elasticity of demand (PED) and then use it to calculate marginal revenue (MR).

PED = (% change in quantity demanded) / (% change in price)

[tex]PED = (dQ/Q) / (dP/P)[/tex]

[tex]PED = (1/2)(S^{1/2})(P^{-2}) / (-2)(S^{1/2})(P^{-3})[/tex]

[tex]PED = -P / 4S[/tex]

Now we can calculate MR:

[tex]MR = P(1+1/PED)[/tex]

[tex]MR = P(1 - P/4S)[/tex]

1. To find the profit-maximizing price, we need to set MR equal to marginal cost (MC):

[tex]MR = MC[/tex]

[tex]P(1 - P/4S) = 10 + 0.08P[/tex]

[tex]P - P^2/4S = 125[/tex]

[tex]P^2 - 500P + 5000S = 0[/tex]

Using the quadratic formula, we get:

P = (500 ± √(500² - 4(1)(5000S))) / (2(1))

P = (500 ± √(250000 - 20000S)) / 2

Since we cannot have a negative price, we take the positive square root:

P = (500 + √(250000 - 20000S)) / 2

Therefore, the profit-maximizing price for the newspaper is (500 + √(250000 - 20000S)) / 2.

2. When S = 100, we can substitute it into the demand equation to find the quantity demanded at the profit-maximizing price:

[tex]Q = 12S^1/2P^{-2[/tex]

[tex]Q = 12(100)^{1/2}[(500 + \sqrt{(250000 - 20000(100)} )) / 2]^{-2}[/tex]

Q ≈ 2,907

Therefore, approximately 2,907 copies will be sold at the profit-maximizing price when S = 100.

Intermediate goods are goods that are used to produce other goods. They are goods that are used in the production process and are not bought for direct consumption.

For example, raw materials, components, and machinery are all intermediate goods. GDP excludes the value of intermediate goods because they are already included in the value of the finished goods. The value of the goods that are used to produce the final product is included in the price of the finished goods.

This is why GDP only includes the value of finished goods and services. Including the value of intermediate goods would create double counting and an incorrect measure of economic activity.

iv. Demand in this model:

In this model, demand represents the total investment demand (I) in the economy. It is negatively related to the interest rate (r), as a higher interest rate will increase the cost of borrowing for investment and reduce the total investment demand.

v. Difference in interest rate between Small Open-Economy and Closed-Economy Loanable Funds Model:

In the Closed-Economy Loanable Funds Model, the interest rate is determined solely by the interaction of domestic saving and domestic investment demand. However, in the Small Open-Economy Loanable Funds Model, the interest rate is also influenced by capital inflows from abroad (F) and net exports (NX). If the capital inflows from abroad increase, they will increase the supply of funds available for investment and reduce the interest rate. Similarly, if net exports increase, they will increase the national income (Y) and increase the demand for funds, leading to an increase in the interest rate.

The Fisher Effect explains how there is a one-for-one adjustment of the nominal interest rate to the inflation rate. This means that when there is inflation, the nominal interest rate will adjust to compensate for it.

However, it is important to note that the government should not solely rely on printing money to generate revenue, as this can lead to higher inflation rates. Instead, they should consider other options such as taxation and borrowing. Additionally, the Fisher Effect also explains how higher money supply growth can lead to higher inflation, as an increase in money supply can lead to an increase in demand for goods and services, which can drive up prices.

Based on the provided data, the hospital exhibits scale economies but no scope economies. The correct answer is D) scale economies but no scope economies. E) both scope and scale economies.

Scale economies occur when the cost per unit decreases as production output increase. In this case, the cost of producing both Q1 and Q2 decreases as the quantity produced increases, indicating the presence of scale economies.

Scope economies, on the other hand, occur when the cost per unit decreases as the variety of services offered increases.

However, in this case, the cost of producing both Q1 and Q2 together is higher than the sum of the costs of producing each service separately. This indicates the absence of scope economies.


Economies of scale refer to the cost advantage that occurs when output increases, leading to a decrease in the average cost per unit.

Economies of scope refer to the cost advantage that arises when a firm provides multiple products or services together, rather than separately.

In this case, producing both goods together (Q1 and Q2) results in lower combined costs (120, 240, 380, 540) than producing each good separately (sum of individual costs: 50+60=110, 100+130=230, 160+200=360, 240+280=520). This indicates the presence of scope economies.

Additionally, as the output increases for both goods (from 10 to 20, 20 to 30, and 30 to 40), the average cost per unit decreases (e.g., from 120 to 240, 240 to 380, and 380 to 540). This indicates the presence of scale economies.

a) The fixed costs for Jerome's farm are $4.

b) The expressions for average cost, average variable cost, and marginal cost are:

AC(y) = 4/y + y + 1

AVC(y) = y + 1

MC(y) = 2y + 1

c)AC(y) is at its minimum value when output is 2.

d) MC(y) is $5 at the output level of 2.

e)The marginal cost curve is upward sloping at all output levels.

a) The fixed costs for Jerome's farm can be found by determining the cost of production when the output is zero. So, we substitute y=0 in the cost function to get:

c(0) = 0^2 + 0 + 4 = 4

Therefore, the fixed costs for Jerome's farm are $4.

b) Average cost (AC) is the total cost (TC) divided by the output (y). So,

AC(y) = TC(y) / y

Total cost is the sum of fixed cost (FC) and variable cost (VC):

TC(y) = FC + VC(y)

where,

FC = 4

VC(y) = y^2 + y

Thus, the average cost can be written as:

AC(y) = (FC + VC(y)) / y

= (4 + y^2 + y) / y

= 4/y + y + 1

Average variable cost (AVC) is the variable cost per unit of output:

AVC(y) = VC(y) / y

= (y^2 + y) / y

= y + 1

Marginal cost (MC) is the derivative of the total cost function with respect to output:

MC(y) = dTC(y) / dy

= d/dy (FC + VC(y))

= d/dy (y^2 + y + 4)

= 2y + 1

Therefore, the expressions for average cost, average variable cost, and marginal cost are:

AC(y) = 4/y + y + 1

AVC(y) = y + 1

MC(y) = 2y + 1

c) To find the level of output at which AC(y) is at its minimum value, we take the derivative of AC(y) with respect to y and set it equal to zero:

dAC(y) / dy = -4/y^2 + 1 = 0

Solving for y, we get:

y = 2

Therefore, AC(y) is at its minimum value when output is 2.

d) To find the value of MC(y) at the output level of 2, we substitute y=2 in the expression for MC(y):

MC(2) = 2(2) + 1

= 5

So, MC(y) is $5 at the output level of 2.

e) The marginal cost curve is upward sloping at all output levels. This is because the cost function is a quadratic function, which means the marginal cost curve is a straight line with a positive slope. This can also be seen from the expression for MC(y) which is 2y + 1, indicating that MC increases as output increases.

A prisoner's dilemma is a game in which b) the players' payoffs are smaller when both play their dominant strategy compared to when both play a dominated strategy.

In this type of game, two players face a situation where cooperation would lead to a better outcome for both, but each player is incentivized to betray the other for personal gain. This betrayal leads to a worse outcome for both players, as they receive smaller payoffs than if they had cooperated. The dilemma arises because each player is unable to trust the other, even though cooperation would be mutually beneficial.

This lack of trust results in both players choosing their dominant strategy (betrayal), which ultimately leads to a less desirable outcome for both compared to the dominated strategy (cooperation). The prisoner's dilemma is often used to illustrate challenges in achieving cooperation in real-world situations, such as negotiations, politics, and economics.

The coefficient of own-price elasticity of demand equals 2.25.

Explanation:
The formula for own-price elasticity of demand is:

E = (% change in quantity demanded / % change in price)

Using the information given in the question, we can plug in the values:

E = (90% / -40%) = -2.25

Since we want the absolute value of the coefficient, we drop the negative sign:

E = 2.25

Therefore, the coefficient of own-price elasticity of demand equals 2.25.

To find the coefficient of own-price elasticity of demand, we'll use the formula:

Elasticity of Demand = (Percentage Change in Quantity Demanded) / (Percentage Change in Price)

Given the information in the question:

Percentage Change in Quantity Demanded = 90%
Percentage Change in Price = -40%

Now, plug these values into the formula:

Elasticity of Demand = (90%) / (-40%)

Elasticity of Demand = -2.25

So, the coefficient of own-price elasticity of demand equals -2.25 (rounded to two decimal places).

Option A, where Vijay must decide between Joe's soy ketchup vs. HJ Heinz tomato ketchup, is an example of a consumer-facing switching cost. Switching costs refer to the cost that a consumer incurs when switching from one product to another.

In this case, Vijay must choose between two different types of ketchup, which are likely to have different tastes, textures, and ingredients.

If Vijay has been using one type of ketchup for a long time, it may be difficult for him to switch to a different brand, especially if it means that he will have to give up the taste and quality that he is used to. This creates a switching cost for Vijay, as he must weigh the benefits of trying a new product against the potential cost of losing the taste and quality that he is accustomed to.

Overall, the decision between Joe's soy ketchup and HJ Heinz tomato ketchup represents an example of a consumer-facing switching cost because it requires Vijay to consider the costs and benefits of switching to a different product.
