2. Suppose that there are five different lemonade stands in the same neighborhood. Explain
how the lemonade stands meet most of the conditions of perfect competition

Answers

Answer:

Eventually prices will equalize at all five lemonade stands.

Explanation:

Perfect competition is accomplished when, in an appropriate business, all firms have identical price arrangements and there is an adequately substantial amount of these same firms so that the production arrangement of any one firm has no obvious influence on the cost at which it commodity is marketed.

The lemonade made are similar in taste, thus they are identical products. Thus, if a lemonade seller increases the price of their good, buyers can patronise another lemonade seller. As a result, the price of lemonades would be the same among the five sellers.

Also, there is little or no barriers to entry for lemonade sellers.

A perfect competition is a market were there are numerous buyers and sellers of homogenous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.

Imagine your 16-year-old daughter wants to attend a Friday night high school party, and you do not know who will be attending. Using three parenting styles discussed in the lesson, how would an authoritarian parent respond? A democratic parent? A permissive parent? Construct a list of the five most important things a person should do to prepare for parenthood. Discuss which one is most important to you.

Answers

Answer:

Follows are the solution to this question:

Explanation:

The authoritarian parent would probably respond to her daughter from the above situation. So, they will not enable themselves to go to the party because they would focus on the idea of just not understanding who's going to a party with an authoritative parent who expects their children not to be interested in some danger. Its progressive parent in the other party will vote to encourage his daughter to join the party since they do not know who is present will probably speak to your daughters about the situation and think over whether or not it is acceptable. Eventually, a permissive parent will not matter and encourage only his daughter to join throughout the party. Since the type of parenting is low or offers just a few guidelines, it's indeed possibly a friend instead of a mom.

List:

It provides adequate income to maintain the child. It becomes prepared, specifically if he/she needs you most, to be there for the kid. It lives in healthy conditions. It secures an automobile ride. We think the most significant one would be the number two because the kid can never remember when it or she wants mommy and daddy a most, and it wasn't there to help him and her and direct him or her having a child healthy crib, with diapers, diapers, formulation, etc.

How would you explain the large increase in 2019 dividends? The large increase in free cash flow from 2018 to 2019 explains the large increase in 2019 dividends. The large increase in net income from 2018 to 2019 explains the large increase in 2019 dividends. The large increase in EBIT from 2018 to 2019 explains the large increase in 2019 dividends. The large increase in sales from 2018 to 2019 explains the large increase in 2019 dividends. The large increase in retained earnings from 2018 to 2019 explains the large increase in 2019 dividends.

Answers

Answer: The large increase in free cash flow from 2018 to 2019 explains the large increase in 2019 dividends

Explanation:

Dividends are the rewards that are given to the shareholders of a company which can be in form of cash, stock etc.

The dividend for the company in 2018 was lower while the 2019 dividend was much higher. The reason for the large increase in the 2019 dividend is due to the increase in the free cash flow from 2018 to 2019.

It should be noted that free cash flow simply means the cash that remains when the company has paid for its expenditures. In this case, since the amount left is large, it also invariably resulted in a larger dividend in 2019.

Which tool of monetary policy allows the Federal Reserve to increase the
money supply?
A. Increasing the discount rate on short-term loans
B. Selling treasury securities on the open market
C. Reducing the reserve requirement on banks
D. Raising interest on reserves paid to banks

Answers

Answer:

C. Reducing the reserve requirement on banks

The Federal Reserve( Fed) expects commercial banks to maintain a percentage of customer deposits in their custody. The amount that the banks keep is known as reserves. The Fed sets the percentage of deposits to be held as reserves. The Fed may adjust this percentage in line with its monetary objectives.

By reducing the reserve requirements percentage, commercial banks remain with a bigger portion of deposits that they lend out. It means banks will issues out more loans to customers. An increase in lending adds more money to the economy. Reducing the reserve requirement increases the money supply in the country.

Why does a business often reach a point at which adding more resources does not increase productivity or profits at the same rate it used to? (diminishing returns, stages of production)

Answers

Answer:

diminishing returns,

Explanation:

The law of diminishing marginal returns claims that the returns from the input will first increase at an increasing rate until production reaches an optimal level. After the optimal level, and holding the other factors constant, the returns from the output will start diminishing and eventually turn negative.

Diminishing returns concepts apply in the short term, where only variable inputs can change. For example, in a factory setting, the optimal production capacity is fixed in the short-run. Additional usage of a variable such as labor increase returns until the factor reaches its optimal capital. Additional hiring of labor results in diminishing returns in labor output.

The law of diminishing marginal returns claims that the returns from the input will first increase at an increasing rate until production reaches an optimal level. After the optimal level, and holding the opposite factors constant, the returns from the output will start diminishing and eventually turn negative.

Diminishing returns

Diminishing returns concepts apply within the short term, where only variable inputs can change. for instance, in a very factory setting, the optimal production capacity is fixed within the short run. Additional usage of a variable like labor increase returns until the factor reaches its optimal capital. Additional hiring of labor leads to diminishing returns of parturient output.

Answers

Answer:

Real GDP - measure of economic output adjusted to inflation or deflation

Nominal GDP -  measure of economic output before adjusting for inflation

Gross National Product - right measure of a country's economic output produced all over the world

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export

Explanation:

Suppose you are an analyst in the oil refinery industry and are responsible for estimating the equilibrium price and quantity of home heating oil. To do so, you must consider factors that can affect the supply of and demand for heating oil. Determinants of the demand for heating oil include household income, the price of an oil furnace (a complementary good for heating oil), and the price of natural gas (a substitute good for heating oil). Determinants of the supply of heating oil include the cost of crude oil and the cost of refining crude oil into home heating oil.

Answers

Please find attached full question

Answer and Explanation:

Equilibrium price refers to the price in the market at which quantity demanded equal to quantity supplied. The price is indicated by the price level where the demand and supply curve intersect. We see that the price in our graph is $40 where demand and supply intersect

Equilibrium quantity is the quantity in the market where the quantity demanded is equal to quantity supplied. This is indicated by the quantity that meets the intersection in the graph. Our equilibrium quantity is therefore 80000 barrels
