Gale-Shapley algorithm for the marriage market can be used to find a stable matching. This algorithm uses a sequence of iterations, with each iteration consisting of a set of proposals. In each iteration, each man proposes to his preferred woman who has not yet rejected him.

The Gale-Shapley algorithm follows a simple procedure, which is as follows:

Step 1: Initialize all men and women to be free.

Step 2: While there is a free man m who has not proposed to all women, do the following: Let w be the woman m proposes to who has not rejected him. If w is free, then they are engaged. Else, suppose w is currently engaged to another man, m'. If w prefers m to m', then she accepts m's proposal and becomes engaged to m. m' becomes free. If w prefers m' to m, then she rejects m's proposal, and remains engaged to m'.

The algorithm can be applied to the given problem by following these steps:

Step 1: Initialize all men and women to be free.

Step 2: Let's start with Man 1. He will propose to his preferred partner. Man 1 will propose to Woman 3 because his utility from Woman 3 is higher. Woman 3 is now engaged to Man 1.

Step 3: Since Woman 3 has been engaged, Man 2 will propose to his preferred partner. Man 2 will propose to Woman 1 because his utility from Woman 1 is higher. Woman 1 is now engaged to Man 2.

Step 4: Man 3 will propose to Woman 4 because his utility from Woman 4 is higher. Woman 4 is now engaged to Man 3.

Step 5: Man 4 will propose to Woman 2 because his utility from Woman 2 is higher. Woman 2 is now engaged to Man 4. The final matching is Man 1 - Woman 3, Man 2 - Woman 1, Man 3 - Woman 4, and Man 4 - Woman 2.

The paper "Is the price right?

The role of economic tradeoffs in explaining reactions to price surges" written by Julio J. Elias, Nicola Lacetera, and Mario Macis is about understanding the behavior of consumers towards the price changes of goods and services in different contexts.

The paper discusses how consumers react to price surges in various scenarios and what economic tradeoffs are involved in their decision-making process.

The broader context of the paper is the field of behavioral economics, which aims to understand how psychological, social, and emotional factors influence economic decisions. The paper draws from previous research in this field to examine the impact of price changes on consumer behavior.

The authors argue that consumers' reactions to price surges are not solely based on their economic value but also on other factors like fairness, trust, and social norms. They analyze different case studies to demonstrate how these factors play a role in consumer behavior and provide suggestions for policymakers and businesses to better understand and address these issues.

The relevance of this paper for day-to-day lives is significant as it sheds light on how consumers make decisions about purchasing goods and services. It suggests that price changes may not be the only factor that influences consumer behavior, and other factors like social norms and fairness also play a role.

Therefore, businesses and policymakers should consider these factors when making decisions about pricing and marketing. Consumers can also benefit from understanding these factors and making more informed decisions about their purchases.

Overall, this paper provides valuable insights into the complexities of consumer behavior and its implications for the economy and society.

Answer:12/17

Explanation:Using the formula for conditional probability, we have:

P(B|A) = P(A and B) / P(A)

We can find P(A and B) by noticing that there are 12 students who passed the test and completed the assignment. Therefore:

P(A and B) = 12/21

To find P(A), we need to consider all the students who passed the test, regardless of whether they completed the assignment or not. This includes the 12 students who passed the test and completed the assignment, as well as the 5 students who failed the assignment but did not complete it. Therefore:

P(A) = (12 + 5)/21

Now we can plug these values into the formula for conditional probability:

P(B|A) = (12/21) / ((12 + 5)/21)

Simplifying this expression, we get:

P(B|A) = 12/17

Therefore, the probability that a student who passed the test completed the homework is 12/17.

The statement "that one out of every three collisions results in an injury" is generally true. However, this statistic can vary greatly depending on the type of road and the type of vehicles involved.

For example, accidents on rural roads tend to be more severe than those on highways, and collisions involving large vehicles like trucks and buses are more likely to result in injuries than collisions between two cars.

Injuries resulting from car accidents are also affected by the speed of the vehicles. The faster the cars are going, the more force is exerted during the collision and the more likely an injury will result. Even at lower speeds, people can still be injured, especially if the cars are heavier or if the drivers are not wearing seatbelts.

In addition, the severity of an injury resulting from a car accident can depend on the type of vehicle. For instance, cars are designed to absorb impact, but motorcycles and bicycles are not, making their riders more vulnerable in a crash.

Overall, the statement that one out of every three collisions results in an injury is an accurate reflection of the current state of traffic accidents. However, the actual likelihood of injury can vary depending on the circumstances of the accident, such as the type of road, speed of the vehicles, and type of vehicles involved.

Both games feature a stag hunter as a successful approach. As a result, it can be described as an asymmetric game.

According to game theory, the stag hunt is a game that highlights a conflict between individual safety and group unity.

                                  Assurance game, coordination game, and trust conundrum are some of the various names for it or its variants. According to Jean-Jacques Rousseau's account of the scene, two people go hunting.

We are aware that the Nash equilibrium presumes that there are two or more participants in a non-corporative game. This means that no player would benefit from changing their playing style because one person knows the equilibrium strategy of all the other players.

1. Each player will hunt the stag if they all lean toward hares by a factor of 1/10. The primary tactic in this situation is the hunt for the stag.

2. Mixed-approach Nash equilibrium (MSNE): The tracker of the stag tends to chase the stag with a probability of 1/7 and the hunter of the hares with a probability of 1/8.

As a result, in both games, the stag hunter makes a winning strategy. As a result, it might be considered an asymmetrical game.

The partial first derivatives of z with respect to x and y are βy²/x + γ/x + 3δy and 2βxy + 3δx, respectively.

The given expression is,

z= αx + βxy² + γ ln(x) + δ3xy

where α, β, γ, δ are constants.

To find the partial first derivatives of z with respect to x and y, we apply the following formulas:

∂z/∂x = α + βy²/x + γ/x + 3δy

∂z/∂y = 2βxy + 3δx

Therefore, the partial first derivative of z with respect to x is:

∂z/∂x = α + βy²/x + γ/x + 3δy

Here, α, β, γ, and δ are constants. Thus, their derivatives with respect to x are zero.

Therefore,

∂z/∂x = βy²/x + γ/x + 3δy

Now, the partial first derivative of z with respect to y is:

∂z/∂y = 2βxy + 3δx

Here, α, β, γ, and δ are constants. Thus, their derivatives with respect to y are zero.

Therefore,

∂z/∂y = 2βxy + 3δx

The total cost of becoming a homeowner in the first year is:$14,400 - $1,500 = $12,900. The cost of becoming a homeowner in the first year is $12,900.

The cost of becoming a homeowner the first year can be calculated by determining the amount of interest paid on the mortgage and the amount earned from the savings account.

Let us solve it using the given information.

Bank lend = $240,000

Interest rate = 6%

Annual interest = 6% of $240,000 = $14,400

In this case, the homeowner has a savings account with the same bank that pays 2.5% interest per year. Thus, the savings account will earn an interest of 2.5% on the initial savings account balance that is equal to the $300,000 house price minus the $240,000 loan amount.

We know: Savings account interest rate = 2.5%Savings account balance = $300,000 - $240,000 = $60,000Annual interest earned = 2.5% of $60,000 = $1,500
