What Is Marginal Analysis?

Marginal analysis examines the additional benefits of a business activity, com💯pared to its cos♈ts. Companies use marginal analysis as a decision-making tool to help them maximize their potential profits.

In economics, marginal refers to the incremental cost or benefit of the next unit or individual. For example, a factory might look at the 澳洲幸运5官方开奖结果体彩网:marginal cost of producing one more widget or the 澳洲幸运5官方开奖结果体彩网:marginal profit earned by hiring one more worker.

Understanding Marginal Analysis

Marginal analysis is widely used in 澳洲幸运5官方开奖结果体彩网:microeconomics to analyze how a complex system is affected by marginal manipulation of its comprising variables. In this💯 sense, marginal analysis focuses on examining the results of small changes as the effects cascade across the business as a whol🥀e.

The♔ goal of marginal analysis is to determine if the additional benefits associated with a change in activity will offset its additional costs. Instead of focusing on business output as a whole, marginal analysis focuses on the cost of producing or consuming one more unit of a good.

Marginal analysis can also help in the decision-making process when there are two potential investments to choose from, but only enough funds for one. By compar🤡ing the associated costs and estimated benefits, marginal analysis can help determine if one option will result in higher profits than the other.

Marginal Analysis and Observed Change

From a microeconomic standpoint, marginal analysis can aꦉlso relate to observing the effects of small changes within the standard operating procedure or total outputs.

For example, a business may attempt to increase output by 1% and analyze the positive and negative effects of the c🤪hange, such as changes in overall product quality or how the change impacts the use of resources.

If the results of the chanไge are positive, the🐲 business may choose to raise production by 1% again and reexamine the results. These small shifts and the associated changes can help a production facility determine an optimal production rate.

Marginal Analysis and Opportunity Cost

Managers should also understand the concept of opportunityꦺ cost. Suppose a manager knows that there is room in the budget to hire an additional factory worker. Marginal analysis tells the manager that an additional factory worker provides a net marginal benefit. This does not necessarily make ꧑the hire the right decision.

Suppose the manager also knows that hiriꦅng an additional salesperson yields an even larger net marginal benefit. In this case, hiring a factory worker is the wrong decision because it is sub-optimal.

How to Perform a Marginal Analysis

Marginal analysis is as simple as taking the margin benefit of an outcome and subtracting the marginal cos🐠t. However, this analysis may be difficult to assess as there are many variables and moving parts to consi💃der. To perform a marginal analysis, you should first understand the fixed and variable costs of an activity. Because the fixed costs are not likely to change, your marginal cost will often be equal to your variable expenses.

Next, you can begin marginal anaꦓlysis by finding the marginal cost and the marginal expense of the activity. This will simply be the change in cost (or benefit) for every unit consumed or acquired. Note that while one aspect may remain the same (either the benefit or the cost may be constant), one aspect will often be variable.

Consider the example of consuming pizza at $2/slice. In this example, marginal cost is easy to quantify, as every additional slice of pizza has a marginal cost equivalent to $2. On the other hand, marginal benefit may be more difficult to quantify. If you haven't eaten all day and are hungry, you may state that the first slice of pizza you eat is worth $10 to you. If this is the case, marginal analysis gives the slice a net benefit of $8 ($10-$2).

To continue performing marginal analysis, consider how both the benefit and the cost will change with each slice of pizza consumed. If each slice costs $2, your marginal cost will always be $2. However, as you eat more pizza, you'll become full, reducing the benefit of each additional slice. There will be a point where you may get sick and begin to have negative marginal benefit for each additional slice eaten.

Rules of Marginal Analysis

When performing marginal analysis, there are two profit maximization rules to consider. Thes⛎e two rules dictate the point at which companies should manufac🌼ture goods and allocate resources.

Rule #1: Operate Until Marginal C🌼ost Equals Marginal Revenue

The overarching rule of marginal analysis is that it is usually in a company's best interest to perform an activity as long as the marginal revenue is greater than the marginal cost. When marginal revenue and marginal cost are equal, there is theoretically no financial incentive for the company to continue the activity, though there may be non-financial factors to consider.

Consider a manufacturing example where it costs $2 to make a good whose marginal revenue is $5. For this unit, the company makes $3. If the next unit costs $4 to make, the company still earns a marginal profit because marginal revenue of $5 is greater than the marginal cost. If the next unit were to cost $6 to make, it would no longer be financiallyꦰ feasible to make and sell the good.

The point at which marginal revenue and marginal cost intersect is often called marginal equilibrium. It is the point at which total company profit is maximized, even if unit profit is not at its highest. Using the pizza example above, you should continue to consume pizza as lಞong as you think the marginal benefit of each slice is worth at least $2 per piece.

Rule #♊2: Equalize Marginal Return Across Pro🀅ducts

Another important rule related to marginal analysis relates to companies that have different products. If a company chooses to only dedicate resources to one product, the potential marginal reven🔯ue of the other products is foregone in favor of a product likely with a diminishing marginal profit. To avoid this, every product should have an equal marginal revenue to maximize the benefit obtained, especially if there are resource constraints at play.

Consider the table below outlining the marginal return received from two products. If one unit of Product A is consumed, the consumer receives a marginal benefit of 100. If one unജit of Product B is consumed, the consumer receives a marginal benefit of 50.

Based on the table above, this second rule would dictate that the first unit consumed should be one unit of Product A. However, we now know the marginal return of a second unit of Product A only yields a return of 25. This second rule would call for the consumer to consume units of Product B until the marginal revenue of the two products meet. In this example, the highest return would occur after 1 unit of Product A and 3 units of Product B have been consumed.

Let's return once more to our pizza example. Instead of only consuming pizza, imagine the marginal benefit of having a refreshing drink in between bites or slices. The argument here is instead of trying to maximize the benefit of eating pizza alone, you should try to have the marginal benefit received from the pizza (considering its price) equal to the marginal benefit received from a drink (also considering its price).

Marginal Cost vs. Marginal Benefit

A marginal benefit (or marginal product) is an incremental increase in a consumer's benefit in using an additional unit of something. A marginal cost&nbs🥃p;is an incremental increase in the expense a co🙈mpany incurs to produce one additional unit of something.

Marginal benefits normally decline as a consumer decides to consume more and more of a single good. For example, imagine a consumer who decides that they need a new piece of jewelry for their right hand. They head to the mall and buy the perfect ring for $100, and then they spot another.🧸

Since the customer has no need for two rings, they would be unwilling to spend another $100 on a second one. They might, however, be convinced to purchase that second ring at $ꦕ50. Therefore, the marginal benefit of the second ring falls from $100 to $50.

If a company has 澳洲幸运5官方开奖结果体彩网:economies of scale, the marginal costs decline as the company produces more and more of the s🌼⛎ame good.

For example, imagine a company that makes fancy widgets in high demand. D🤡ue to this demand, the company can afford machinery that reduces the average cost to produce each widget; the more they make, the cheaper they become. On average, it costs $5 to produce a single widget, but because of the new machinery, the 101st widget only costs $1. Therefore, the marginal cost of producing the 101st widget is $1.

Limitations of Marginal Analysis

Marginal analysis derives from the economic theory of marginalism—the idea that human actors make decisions on the margin. Underlying marginalism is another concept: the subjective theory of value. Marginalism is sometimes criticized as one of the "fuzzier" areas of economics. Much of what it proposes is hard to accurately measure, su♔ch as an individual consumer's marginal utility.

Also, marginalism relies on the assumption of (near) perfect markets, wh🔜ich do not exist in the practical world. Still, the core ideas of marginalism are generally accepted by most economic schools of thought and are still used by businesses and consumers to make choices and substitute goods.

Modern marginalism approaches now include the effects of psychology or those areas that now encompass behavioral economics. Reconciling ne🧜oclassical economic principles and marginalism with the evolving body of behavior🐼al economics is one of the emerging areas of contemporary economics.

Since marginalism implies subjectiv𒁏ity, economic actors make marginal decisions based on how valuable they appea🍒r to be. Marginal evaluations might later be considered regrettable or mistaken.

This can be demonstrated in a cost-benefit scenario. A company might make the decision to build a new plant because it anticipates that the future revenues from the new plant will exceed the costs of building it. If the company later discovers that the plant 澳洲幸运5官方开奖结果体彩网:operates at a loss, the🐷n it must be concluded that the company miscalculat💞ed the cost-benefit analysis.

That said, inaccurate calculations reflect inaccuracies in cost-benefit assumptions and measurements. Predictive marginal analysis is limited to human understanding and reason. When marginal analysis is applied reflectively, however, it can be more r💙eliable and accurate.

Example of Marginal Analysis in Manufacturing

When a manufacturer wiꩵshes to expand its operations by adding new product lines or increasing the production of a current product line, it will start by conducting a marginal analysis. It may consider the costs🌃 of any additional manufacturing equipment, the additional employees needed to support an increase in output, the cost of additional manufacturing or storage facilities, and the cost of additional raw materials to produce the goods.

Once all of the costs are identified and estimated, these amounts are compared to the estimated increဣase in sales attributed to the additional production. This analysis takes t♔he estimated increase in income and subtracts the estimated increase in costs. If the increase in income outweighs the cost increases, the expansion may be a wise investment.

For example, consider a hat manufacturer. Each hat produced requires seventy-five cents of plastic and fabric. The🌺 hat factory incurs $100 dollars of fixed costs per month. If you ma✤ke 50 hats per month, then each hat incurs $2 of fixed costs.

In this simple example, the total cost per hat, including the plastic and fabric, would be $2.75 ($2.75 = $0.75 + ($100/50)). But, if you cranked up production volume and produced 100 hats per month, then each hat would incur $1 dollar of fixed costs because fixed costs are spread out across more units of output. The total cost per hat would then drop to $1.75 ($1.75 = $0.75 + ($100/100)). In this situation, increasing production volume causes marginal costs to go down.

How Will I Use This in Real Life?

Even if you never work in business or economics, you are constantly using maꦚrginal analysis to make decisions about your consumption habits. Whenever you decide to consume (or not consume) a particular good, your mind is performing a mental calculation about the benefits of additional consumption in comparison to the costs.

In some cases, the marginal analysis starts before you get out of bed. When your alarm goes off, you may hit the "Snooze" button and sleep for an extra few minutes. In economic terms, the marginal benefit of sleeping a little later is greater than the marginal cost of a rushed morning. With each additional minute of sleep, the marginal benefit decreases and the marginal cost increases, until you decide there is a greater benefit in getting up.

The Bottom Line

Marginal analysis is a critical part of a business and life that dictates 🃏what leve🐼l of activity to operate at. Marginal analysis discovers the point at which marginal revenue equals marginal cost.

If someone operates below this point, they may not be taking advantage of business opportunities. If someone operates above this point, they may lose resources every unit. Marginal analysis drives how many units a company produces and 澳洲幸运5官方开奖结果体彩网:often decides what (and how much) cons⛦umers buy.
