7. The quantity demanded for this good has decreased from 505 to 495. What is the percentage decrease in quantity based on the mid-point formula?
8. Calculate the price elasticity of demand for this good.
The percentage decrease in quantity demanded for this good can be calculated using the mid-point formula, which is the percentage change in quantity divided by the average of the initial and final quantities. Thus, the percentage decrease in quantity is calculated as: (505 - 495) / (505 + 495) / 2 = 10 / 1000 = 0.01 = 1%.
The price elasticity of demand for this good can be calculated by dividing the percentage change in quantity demanded by the percentage change in price. In this case, the price elasticity of demand is calculated as: -1% / 1% = -1.
This indicates that the demand for the good is relatively inelastic, meaning that a 1% increase in price would cause a 1% decrease in quantity demanded. This shows that the demand for the good is relatively insensitive to price changes, and that the good would need to have a significant decrease in price to drive an increase in quantity demand.

In a math class with 21 students, a test was given the same day that an assignment was due. There were 12 students who passed the test and 13 students who completed the assignment. There were 5 students who failed the test and also did not complete the assignment. What is the probability that a student who passed the test completed the homework?
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.

Explain and draw a supply and demand curve for a normal good showing the equilibrium point. Explain the difference between moves along the curves and shifts in the curves. Give examples of what would cause movement and what would cause shifts and show the movement on your graph. 2)The government gets involved in the marketplace for many reasons. One reason is to ensure the welfare of the public. To help people they sometimes put in price ceilings and price floors. Use the examples of minimum wage and rent control to explain the benefits and detriments of government involvement. Include graphs of each one to show how they work. 3) Draw a demand curve from the accompanying demand schedule. Show where the curve is elastic, inelastic and unit elastic. Use different points on the curve to prove your answer by using the mid-point method. Explain what the different types of elasticity means. Why are firms interested in the type of elasticity of demand? Demand Schedule Price 10987 6 5 4 3 2 1 Quantity 2 46 8 10 1214 16 18 20 4) Why is a Pigovian tax different from a traditional tax? What effect does each have on the marketplace? What do economists prefer when trying to curb an externality, a tax or a regulation? Explain and use graphs
1) A supply and demand curve for a normal good is an economic model that shows the relationship between the quantity of goods and services supplied and the quantity of goods and services demanded in a market.
The equilibrium point is the point at which the two curves intersect and the quantity demanded equals the quantity supplied. The curves can either move along (the amount of goods and services supplied/demanded changes but the curves stay the same) or shift (the curves move either right or left).
2) Price ceilings and price floors are government-imposed price controls. Price ceilings are set at the maximum price that a product or service can be sold at, while price floors are set at the minimum price that a product or service can be sold at.
The benefit of these price controls is that they can help to increase fairness in the marketplace, but the downside is that they can lead to shortages in the market and could reduce the incentive for producers to supply goods and services.
3) The accompanying demand schedule and demand curve are shown below. On the demand curve, elasticity is measured by the slope of the curve. When the slope is steep, the curve is inelastic, when the slope is flat, the curve is unit elastic, and when the slope is somewhere in between, the curve is elastic.
Elasticity is important for firms to know because it affects the amount of money they will make when they adjust the price of their good or service.
4) A Pigovian tax is a type of tax that is imposed on a certain product or service that is causing a negative externality (a cost or benefit to someone other than the consumer or producer of a good or service). The purpose of a Pigovian tax is to internalize the externality and make the consumer or producer pay for the cost of the negative externality.
Traditional taxes are imposed to generate revenue for the government, whereas Pigovian taxes are imposed to reduce or prevent the negative externality. Economists generally prefer the use of taxes over regulations to curb externalities because taxes are more efficient, allow for flexibility, and can lead to higher economic growth.

States has been
A.
such that recessions barely exist.
B.
less than a year.
C.
between 1 and 2 years.
D.
greater than 2 years.
The average length of a recession in the United States since 1950 is less than a year. The correct option is B.
A recession is typically defined as two consecutive quarters of negative economic growth, or a significant decline in economic activity.
During a recession, businesses can experience reduced demand and decreased production, leading to fewer jobs, lower wages, and weaker consumer confidence. This can have a ripple effect on the economy, as consumers have less money to spend, leading to further economic decline.
Recessions can last anywhere from a few months to several years. During the Great Recession, which began in 2007, the US economy experienced an extended period of contraction, lasting from late 2007 until mid-2009. This was the longest recession since the Great Depression, with a total length of 18 months.
Since the 1950s, the majority of recessions have been relatively brief, with most lasting less than two years. During this period, the average recession lasted for around 10 months. While some recessions were as short as 6 months, others lasted for up to 16 months.
It is important to note that the duration of a recession can vary greatly, depending on various factors.
Some recessions can be mild, while others can be severe and prolonged. In addition, recessions can differ in terms of their cause and impact on the economy. Understanding these factors can help policy makers and businesses plan for and manage recessions.

(b) Assuming that men propose, apply the Gale-Shapley algorithm to find a marriage market equilibrium – a stable matching. [45 marks]
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 use of multiple housing in urban economics results in less per-capita land use than single-family housing, allowing for the efficient use of urban land. Multiple housing in urban economics allows for a diverse range of housing types to be constructed, catering to a variety of income levels.
Examples of multiple housing in urban economics
1. Apartments
2. Townhouses
3. Duplexes
4. Condominiums
5. Row houses
These are some examples of multiple housing in urban economics. Apartments, for example, are used all over the world to provide affordable housing for people in cities.

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

This will help reduce the amount of time it takes for goods to be transported, reducing the likelihood of congestion and delays. Increasing the use of technology: Technology can help improve the visibility of supply chain processes. This can be achieved by implementing digital tracking systems, which will provide real-time information about the location and status of goods. This will help identify bottlenecks in the supply chain and enable companies to take corrective measures in a timely manner.
Increasing inventory levels: By increasing inventory levels, companies can reduce the impact of supply chain disruptions. This will ensure that there is an adequate supply of goods even in the event of delays or other issues. Implementing risk management strategies: Companies can implement risk management strategies, such as diversifying their supplier base, to minimize the impact of supply chain disruptions. This will ensure that there are alternative sources of supply available in the event of disruptions, reducing the likelihood of delays and shortages.
