Consider a Diamond-Dybvig economy with a single consumption good and three dates (t = 0, 1, and 2). There is a large number of ex ante identical consumers. The size of the population is N > 0. Each consumer receives one unit of good as an initial endowment at t = 0. This unit of good can be either consumed or invested.
At t = 1, each consumer finds out whether he/she is a patient consumer or an impatient consumer. The probability of being an impatient consumer is 1∈(0,1) and the probability of being a patient one is 2=1−1. Impatient consumers only value consumption at t = 1. Their utility function is (1), where 1 denotes consumption at t = 1. Patient consumers only value consumption at t = 2. Their utility function is given by (2), where 2 denotes consumption at t = 2 and ∈(0,1) is the subjective discount factor. The function () is strictly increasing and strictly concave, i.e., ′()>0 and ′′()<0.
Consumers can buy or sell a single risk-free bond after knowing their type (patient or impatient) at t = 1. The price of the bond is p at t = 1 and it promises to pay one unit of good at t = 2. There is a simple storage technology. Each unit of good stored today will return one unit of good in the next time period. Finally, there is an illiquid asset. Each unit of illiquid investment will return >1 units of good at t = 2, but only ∈(0,1) units if terminated prematurely at t = 1.

(b) Explain why the bond market is in equilibrium only when p =1. Derive the optimal level of illiquid investment in the bond market equilibrium.

Answers

Answer 1

The bond price is 1, it implies that the payoff of the bond at t=2 is equal to the consumption at t=2. Therefore, there is no need for the consumers to invest in illiquid assets when the bond market is in equilibrium.

(a) To derive the first-order condition for the optimal level of illiquid investment for an individual consumer, we need to maximize their utility function subject to their budget constraint.

For an impatient consumer, the utility function is given by:

U_i(t=1) = ln(C_i(t=1))

where C_i(t=1) represents the consumption of the impatient consumer at t=1.

For a patient consumer, the utility function is given by:

U_p(t=2) = ln(C_p(t=2))

where C_p(t=2) represents the consumption of the patient consumer at t=2.

Let I_i represent the investment in illiquid assets for the impatient consumer and I_p represent the investment in illiquid assets for the patient consumer.

The budget constraint for both consumers at t=1 is:

C_i(t=1) + I_i = 1

The budget constraint for the patient consumer at t=2 is:

C_p(t=2) + (1-p)I_p = 1

where p represents the price of the bond at t=1.

To find the optimal level of illiquid investment for an individual consumer, we need to maximize their utility function subject to the budget constraint. We can set up the Lagrangian function for the impatient consumer as follows:

L_i = ln(C_i(t=1)) + λ_i(C_i(t=1) + I_i - 1)

Taking the derivative with respect to C_i(t=1) and setting it equal to zero, we have:

∂L_i/∂C_i(t=1) = 1/C_i(t=1) + λ_i = 0

Solving for λ_i, we get:

λ_i = -1/C_i(t=1)

Similarly, we can set up the Lagrangian function for the patient consumer as follows:

L_p = ln(C_p(t=2)) + λ_p(C_p(t=2) + (1-p)I_p - 1)

Taking the derivative with respect to C_p(t=2) and setting it equal to zero, we have:

∂L_p/∂C_p(t=2) = 1/C_p(t=2) + λ_p = 0

Solving for λ_p, we get:

λ_p = -1/C_p(t=2)

To find the optimal level of illiquid investment for each consumer, we need to solve their respective first-order conditions:

For the impatient consumer:

1/C_i(t=1) = λ_i

1/C_i(t=1) = -1/C_i(t=1)

Simplifying, we get:

C_i(t=1) = 1

Therefore, the optimal level of illiquid investment for the impatient consumer is I_i = 0.

For the patient consumer:

1/C_p(t=2) = λ_p

1/C_p(t=2) = -1/C_p(t=2)

Simplifying, we get:

C_p(t=2) = 1

Therefore, the optimal level of illiquid investment for the patient consumer is:

C_p(t=2) + (1-p)I_p = 1

(1-p)I_p = 0

I_p = 0

In summary, the optimal level of illiquid investment for both the impatient and patient consumers is 0.

(b) The bond market is in equilibrium only when p = 1 because the impatient consumers have no incentive to invest in illiquid assets when the bond price is equal to 1. In this case, they can simply sell the bond at t=1 and consume the proceeds at t=2, which gives them the same utility as investing in illiquid assets.

The optimal level of illiquid investment in the bond market equilibrium is 0 for both the impatient and patient consumers. Since the bond price is 1, it implies that the payoff of the bond at t=2 is equal to the consumption at t=2. Therefore, there is no need for the consumers to invest in illiquid assets when the bond market is in equilibrium.

If the profit is the difference between the revenue and the cost, what expression represents the profit? 3x – 260 3x + 140 5x – 260 5x + 140

Answers

Answer:

\(P =5x-260\)

Step-by-step explanation:

Given

\(R = 3x^2 + 4x - 60\) --- Revenue

\(C = 3x^2 - x + 200\) --- Cost

Required

The expression for profit (P)

This is calculated as:

\(P =R - C\)

So, we have:

\(P =3x^2 + 4x - 60 - (3x^2 -x+200)\)

Open bracket

\(P =3x^2 + 4x - 60 - 3x^2 +x-200\)

Collect like terms

\(P =3x^2 - 3x^2+ 4x +x- 60-200\)

\(P =5x-260\)

If the profit is the difference between the revenue and the cost, 5x – 260  expression represents the profit. Correct option is 3.

The profit is calculated by subtracting the cost from the revenue. In mathematical terms, the profit (P) can be represented as:

Profit (P) = Revenue - Cost

Among the given options:

1. 3x - 260

2. 3x + 140

3. 5x - 260

4. 5x + 140

We need an expression where the first term represents the revenue and the second term represents the cost, so that when we subtract the cost from the revenue, we get the profit.

Option 3, 5x - 260, fits this pattern:

- Revenue: 5x

- Cost: 260

When we subtract the cost from the revenue:

Profit (P) = Revenue - Cost = 5x - 260

So, option 3, 5x - 260, is the expression that represents the profit.

Answers

Maximize Z = -2x1 + x2 - 4x3 + 3x4 subject to the following constraints:

x1 + x2 + x3 + 2x4 + s1 = 4,

-x1 + x3 + x4 - s2 = -1,

2x1 + x2 + s3 = 2,

and x1 + 2x2 + x3 + 2x4 = 2, where x1, x2, x3, x4, s1, s2, s3 ≥ 0.

To reformulate the given problem in the standard form of a linear programming model, we need to convert all the inequalities into equations and express all variables as non-negative.

The standard form of a linear programming problem is as follows:

Maximize (Z) = c1x1 + c2x2 + c3x3 + c4x4

Subject to:

Draw a circle over the number to begin plotting an inequality, such as x>9, on a number line (e.g., 9). If the sign also says equal to (or), then complete the circle.

What is inequality in math example?An inequality compares two values and indicates whether one is lower, higher, or just not equal to the other. It is implied by the expression a b that a and b are not equal. If a b, then a must be smaller than b. When a > b, an is greater than b.A relationship between two expressions or values that is not equal to each other is known as inequality in mathematics. So inequality emerges from an imbalance.When resolving an inequality, you can either add or subtract the same amount from each side, or multiply or divide each side by the same positive amount. The inequality sign appears if each side is multiplied or divided by a negative number.

Answers

As per the given triangle RT = AS, RS = AT, the statement < TSA = < STR is proved.

Given two triangles, if the length of one side is proportional to the length of a corresponding side in another triangle, then the two triangles are similar.

This relationship is expressed as "RT = AS," where R and S are corresponding vertices in the two triangles and T is the point where the two sides intersect.

To prove that < TSA = < STR, we need to show that corresponding angles in the two triangles are equal.

This is because corresponding angles in similar triangles are equal, and this is one of the ways to prove that two triangles are similar.

To prove that RT = AS and RS = AT, we can use the function of proportionality. This function states that if two sides are proportional, then the ratio of corresponding lengths will be equal.

Therefore, if RT = AS and RS = AT, then we can conclude that < TSA = < STR and the two triangles are similar.

The change in Linda's distance from Denver for each hour she drives is -65 miles.

The given equation, y=-65x+475, represents a linear relationship between Linda's distance from Denver (y) and the time she has been driving (x). The coefficient of x (-65) represents the rate at which Linda's distance from Denver is changing with respect to time.

Use the quadratic formula to find both solutions to the quadratic equation given below

Use the quadratic formula to find both solutions to the quadratic equation given below 4x^2+3x-1=0

Answers

The solutions to the quadratic equation 4x² + 3x - 1 = 0 are: x = 1/2 and x = -1. None of the answer choices match these solutions, so none of the options provided are correct.

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x. Ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form.

To use the quadratic formula, we need to first identify the values of a, b, and c in the quadratic equation:

ax² + bx + c = 0

In the given equation,

a = 4

b = 3

c = -1

Now, we can substitute these values into the quadratic formula:

\($ \rm x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}\)

Plugging in the values for a, b, and c gives:

x = (-3 ± sqrt(3² - 4(4)(-1))) / 2(4)

\($ \rm x = \frac{ -3 \pm \sqrt{3^2 - 4(4)(-1)}}{2(4)}\)

Simplifying inside the square root:

\($ \rm x = \frac{-3 \pm \sqrt{9 + 16}}{8}\)

\($ \rm x = \frac{-3 \pm \sqrt{25}}{8}\)

\($ \rm x = \frac{-3 \pm 5}{8}\)

Now, we have two solutions:

x = (-3 + 5) / 8 = 1/2

x = (-3 - 5) / 8 = -1

Therefore, the solutions to the quadratic equation 4x² +3x - 1 = 0 are:

x = 1/2 and x = -1

None of the answer choices match these solutions, so none of the options provided are correct.

Find each probability using the table (table is linked)

The table below shows the number of students that do or do not have their own car and whether they have part time jobs.

1. p(a student with a part time job without a car)
2. p(no car | does not have a part time job)
3. p(part time job | car)​

I'm giving brainliest to the most helpful answer. For 50 points:Find each probability using the table

Answers

Answer:

1) \(\displaystyle\frac{5}{18}\approx27.78\%\)

2) \(\displaystyle\frac{4}{7}\approx57.14\%\)

3) \(\displaystyle \frac{13}{16}=81.25\%\)

Step-by-step explanation:

We are given a two-way frequency table. Using the table, we will determine the probability for each case.

Question 1)

P(A Student With A Part Time Job Without A Car)

Using the first column, the total number of students that have a part time job is 78+30=108.

Likewise, using the first column, we can see that out of those 108 students, 30 do not have a car.

Hence, the probability that a student with a part time job without a car is:

\(\displaystyle P=\frac{30}{108}=\frac{5}{18}\approx27.78\%\)

Question 2)

P(No Car | Does Not Have A Part Time Job)

Remember that the vertical line means conditional probability.

So, we want the probability of a student having no car given that they do not have a part time job.

Using the second column, we can see that the total number of students that do not have a part time job is 18+24=42.

Likewise, using the second column, 24 do not have a car.

Hence, the probability that a student with a part time job without a car is:

\(\displaystyle P=\frac{24}{42}=\frac{4}{7}\approx57.14\%\)

Question 3)

P(Part Time Job | Car)

So, we want to probability of a student having a part time job given that they have a car.

Using the first row, the total students that have a car is 78+18=96.

And of those 96 students, 78 have a part time job.

Hence, the probability that a student with a car has a part time job is given by:

\(\displaystyle P=\frac{78}{96}=\frac{13}{16}=81.25\%\)

De acuerdo a su rendimiento de producción diaria, solo 6.0% del producto realizado se desecha: Teniendo en cuenta este rendimiento, ¿cuánto debería ser la producción para que al final tenga 78 125 lb de producto?

a. 82.813 lb

b.4.388 lb.

C. 78.128 lb.

d. 79.588 lb

Answers

The amount of output that should be produced so that you can end up with 78,125 pounds of product is 83, 111. 70 pounds

How to find the output?

Assuming that the amount of output that you should produce to end up with 78,125 pounds is x, the formula to find this amount that should be produced is:

x = (6% × x) + 78, 125

Solving for x gives:

x = 0.06x + 78, 125

x - 0.06x  = 78, 125

0. 94x = 78, 125

x = 78, 125 / 0.94

x = 83, 111. 70 pounds

Note: The options do not contain the correct amount to produce.

Step-by-step explanation:

keys for antique cars had seven parts, with three patterns for each part.(a) how many different key designs are possible for these cars?

Answers

This can be simplified to 3^7, which equals 2,187. So, there are 2,187 different key designs possible for these antique cars.

To determine the number of different key designs possible for antique cars with seven parts and three patterns for each part, we can use the multiplication principle of counting.

This principle states that if there are m ways to perform one action and n ways to perform another action, then there are m x n ways to perform both actions together.

Therefore, the number of different key designs possible can be calculated by multiplying the number of patterns for each part together. In this case, we have three patterns for each of the seven parts, so we can calculate the number of possible designs by using the formula 3^7.

Using a calculator, we can see that 3^7 is equal to 2,187. Therefore, there are 2,187 different key designs possible for antique cars with seven parts and three patterns for each part. It's worth noting that not all of these designs may have actually been produced or used, but this calculation gives us the total number of possibilities based on the given information.
Hi! I'd be happy to help you with your question. To determine the number of different key designs possible for these antique cars, we can use the multiplication principle of counting. Since there are 7 parts to each key and 3 patterns for each part, we can multiply the number of patterns for each part together to find the total number of key designs.

The calculation would be: 3 (patterns for part 1) × 3 (patterns for part 2) × 3 (patterns for part 3) × 3 (patterns for part 4) × 3 (patterns for part 5) × 3 (patterns for part 6) × 3 (patterns for part 7).
