Diseconomies of scale

What is  diseconomies of scale ?

The cost disadvantages that economic actors incur as a result of a growth in organizational size or in output, resulting in the production of goods and services at higher per-unit costs, are known as diseconomies of scale in microeconomics. Economies of scale are opposed by the idea of diseconomies of scale. Diseconomies of scale[1] are the characteristics of a business that cause average costs to rise when it expands past a particular size.

To add, price elasticity of demand (PED or Ed) is a measure used in economics to show the responsiveness, or elasticity, of the quantity demanded of a good or service to a change in its price, ceteris paribus.

Final answer:

The price elasticity of demand refers to the ratio of the percentage change in the quantity demanded of a good or service to the percentage change in the price. It helps us understand how sensitive the demand for a product is to changes in its price.

Explanation:

The price elasticity of demand refers to the ratio of the percentage change in the quantity demanded of a good or service to the percentage change in the price of that good or service.

For example, if the price of a product increases by 10% and the quantity demanded decreases by 5%, the price elasticity of demand would be -0.5.

Mario and luigi want to open up a pizza place. they have determined that the rent will cost them $2,000 per month and administrative salaries will cost $3,000 per month. the variable cost per pizza will be $7.00. mario and luigi estimate they will sell 850 pizzas per month. if mario and luigi sell all 850 pizzas and the only costs they incur are the ones listed above, what is their breakeven price per pizza?

Answers

To determine Mario and Luigi's breakeven price per pizza, sum the fixed costs of rent and salaries ($5,000) and divide by the number of pizzas they plan to sell (850), resulting in a breakeven price of approximately $5.88 per pizza.

Mario and Luigi's breakeven price per pizza can be calculated by adding their fixed costs (rent and salaries) and dividing the sum by the number of pizzas they estimate to sell. The fixed costs include a monthly rent of $2,000 and administrative salaries of $3,000. Adding these together gives us a total fixed cost of $5,000 per month. Since they estimate selling 850 pizzas per month, the breakeven price per pizza is calculated by dividing the total fixed costs by the number of pizzas:

Total Fixed Costs = Rent + Salaries = $2,000 + $3,000 = $5,000

Breakeven Price per Pizza = Total Fixed Costs / Estimated Number of Pizzas Sold = $5,000 / 850 pizzas

Thus, the breakeven price per pizza for Mario and Luigi would be approximately $5.88.

True or false: it doesn’t matter whether you compute marginal cost using total cost or variable cost.

Answers

It is TRUE. Marginal cost is the amount added when there is an additional unit of product or service produced. Meanwhile, the total cost, as defined in accounting, is composed of the total fixed costs and its total variable costs. Fixed cost is not affected by the number of output a company produced. Thus it won’t affect the marginal cost.

When the central bank decides to increase the discount rate, the:?

Answers

Final answer:

Increasing the central bank's discount rate leads to a decrease in commercial banks' borrowing from the central bank, resulting in a reduction of the money supply and a rise in market interest rates as part of monetary policy.

Explanation:

When the central bank decides to increase the discount rate, it affects commercial banks by discouraging them from borrowing reserves from the central bank. Instead, these commercial banks may call in loans to replenish their reserves, leading to a reduction in the overall availability of loans. As a result, the money supply contracts and market interest rates tend to rise. This is a method of conducting monetary policy that directly impacts the economy by controlling the lending capacity of commercial banks.

In recent periods, however, the Federal Reserve has seldom made discount loans, and most banks prefer other borrowing sources before resorting to the Federal Reserve's discount window. While changing the discount rate has become a less predominant tool in impacting banking behavior, it remains a significant symbol of the direction of the Federal Reserve's monetary policy. Particularly, open market operations have emerged as a more effective tool for achieving desired monetary outcomes.

Final answer:

The global recession of 2008 forced firms into bankruptcy, highlighting the impact of external factors on strategic planning. However, this does not confirm that external factors are more important than internal factors.

Explanation:

In strategic planning, both internal and external factors play a crucial role. The global recession of 2008 forced thousands of firms into bankruptcy, indicating the significant impact of external factors on strategic planning. However, this fact alone does not confirm that external factors are more important than internal factors in strategic planning. External factors such as economic downturns, market conditions, and government policies can certainly have a profound effect on businesses. However, internal factors like organizational structure, management decisions, and competitive advantage also play a vital role in shaping a firm's strategic planning.

Pinnacle corporation is a manufacturing company operating numerous machines. these require regular maintenance to keep them operational. the fixed portion of maintenance costs are $3,000 per month. maintenance costs are also incurred at the rate of $5 per setup and $0.50 per unit produced. the company produced 23,000 units in 800 batches during a particular month. what will be the total cost of maintenance for this month?

Answers

Final answer:

The total maintenance cost for Pinnacle Corporation for the month is calculated by adding the fixed maintenance costs, setup costs, and production costs together, which gives a total of $18,500.

Explanation:

To calculate the total maintenance costs for Pinnacle Corporation, we need to take into account the fixed monthly costs, the cost per setup, and the cost per unit produced. The fixed maintenance cost is given as $3,000. The variable costs include $5 per setup and $0.50 per unit.

Therefore, the total cost for the setups can be calculated as:

Setup costs = Number of setups × Cost per setup

Setup costs = 800 × $5

Setup costs = $4,000

Similarly, the total cost for the units produced can be calculated as:

Production costs = Number of units produced × Cost per unit

Production costs = 23,000 × $0.50

Production costs = $11,500

Adding the fixed costs, setup costs, and production costs together:

Total maintenance costs = Fixed costs + Setup costs + Production costs

Total maintenance costs = $3,000 + $4,000 + $11,500

Total maintenance costs = $18,500

The total maintenance cost for the month is $18,500.

In the __________ decision-making method, group members voice their feelings and opinions, but the final decision is made by the boss or leader. authority consensus majority rule unanimous

Answers

The authority decision-making method allows group members to express their opinions, but the leader makes the ultimate decision.

In the authority decision-making method, group members are invited to voice their feelings and opinions, but the boss or leader makes the final decision. This method differs from other common decision-making techniques such as majority rule, where a simple majority is enough to make a decision, and consensus rule, which requires unanimous agreement among all group members before a decision can be finalized.

Authority decision-making can be efficient in terms of time-saving, as it does not require the lengthy process of achieving consensus or majority. However, it also means that the needs and wants of the majority can be overlooked if the authority's decision does not align with them. This method is most effective when the designated authority or expert is highly respected or when the group members lack the knowledge or expertise in the matter at hand.

The marginal cost is the difference between the overall cost of manufacturing and contributing one more unit to a batch. Identifying the point at which a company can attain scale advantages in order to enhance productivity and overall operations is beneficial.

Divide the variation in manufacturing costs from the variation in quantity to determine the marginal cost. The producer may make money if the cost to manufacture one extra unit is lower than the price per unit.
