What is overfill Capacity?

Excess volume (or unutilized capacity) occurs when a certain operates or is creating output at less than the optimum level. That can take place when over there is a industry recessionRecessionRecession is a term offered to represent a slowdown in general financial activity. In macroeconomics, recessions are officially recognized after two consecutive quarters of negative GDP expansion rates. Or increased competition, where demand declines and also firms are forced to alleviate capacity to decrease costs.

To boost demand, companies generally decrease prices when there is excess capacity in the industry. Excess volume is figured out using the minimum long-run mean cost; hence, that is no a short-run occurrence.

Economists generally study excess capacity in the context of industry structures – perfect competitionPerfect CompetitionIn a industry with perfect competition, both producers and consumers space price-takers. Together a characteristic suggests production and also and monopolistic competition – which us will study below.


Excess volume is a instance where a firm walk not produce at optimum or best capacity – mainly because of reduced demand.Excess volume is calculated making use of the minimum long-run mean cost; hence, that is no a short-run occurrence.There is no excess volume in the long run for perfectly competitive markets.

Excess capacity Under Perfect Competition



LAC – Long-run median costLMC – Long-run marginal costAR – typical revenueMR – Marginal revenueOP – PriceOQ – QuantityE – Equilibrium point

Conditions of full equilibrium in a perfect competitive market structure room reached as soon as the demand curve (AR) is tangential come the long-run average price curve (LAC) in ~ its minimum point. This is additionally the point where the LMC = AR = grandfather = LAC.

The equation signifies the in the long run, regardless of the entrance of new firms in the market, existing that company make efficient use of accessible resources to operate at the lowest point of the LAC.

Therefore, in the long run, the optimum output is OQ, and also at the equilibrium allude (E), all firms earn typical profits; abnormal profits are unattainable.

At E, wherein price (OP) and optimum output at the effective scale (OQ), grandfather = LMC – AR = LAC. Consequently, there is no excess volume in the long run for perfectly competitive markets.

Excess volume Under Monopolistic Competition

Excess capacity is more defined under monopolistic competition due to the nature that the industry structure.

Unlike perfectly competitive industries where the need curve is horizontal, monopolistic compete markets display a downward sloping demand curve. The need curve cannot be tangential come the LAC at its minimum point.


Conditions that equilibrium are reached at E, whereby LMC = LAC at the minimum point of the latter. That company in monopolistic vain are most likely to see excess capacity, together there is no motivation to create optimum calculation at a greater long-run marginal cost (LMC) the is higher than marginal revenue (MR).

Firms in monopolistic vain operate below optimum capacity; hence, lock are smaller in size, large in regards to population, and work under conditions of excess capacity.

Firms under monopolistic competition run at the equilibrium suggest E1, where output OQ1 is produced, and the need curve is tangent to the LAC at point A. That is the allude where the LMC curve intercepts with the mr curve.

Firms carry out not run at equilibrium (E), whereby the LMC curve intercepts the LAC curve in ~ its lowest point, and optimum output (OQ) is produced. Beyond OQ1, that company will start making losses as LMC is better than MR. Thus, excess capacity is produced as represented by Q1Q.

The graph also reveals the in the lengthy run, calculation is lower, and also price is greater under monopolistic competition, compared to perfectly competitive industries where calculation is higher and price is lower.

Chamberlin’s see on overfill Capacity

The ide was explained by Prof. Chamberlin. He shown that under monopolistic competition, whereby there is liberty of entry and price competition, the tangency that the need curve and the long-run average price curve would cause optimum output and no excess capacity.

Furthermore, consumers space willing to salary a greater price for distinguished products and also the rise in a selection of goods. Excess volume occurs due to non-price competition regardless of the liberty of entry in a monopolistic competition industry structure.

Chamberlin shown that firms usage the cost of production rather than demand when pricing their products, and they will aim to earn common profits. That company are generally unwilling to mitigate product prices.

In addition, firms emphasis on product differentiation come dissuade fist from price competition. Some will also be led by organization ethics to avoid cut-throat price competition.

Chamberlin’s Assumptions

Prof. Chamberlin excess capacity concept assumes the following:

A big number of that company in the marketFirms produce comparable products independently of each other and also can charge reduced prices to tempt customers from other firms or charge greater prices and lose customers.Consumer choices are evenly distributed across product varieties.No product syndicate by any firmLong-run price curves room U-shaped for every firmsFreedom of entry and also exit


Firms knife abnormal revenues at initial short-run equilibrium suggest S and also price (OP), i beg your pardon is above the long-run average expense (LAC) curve. However, the entry of brand-new firms in the market will ultimately wipe away abnormal profits.

Imaginary demand curve dd is of no product importance if there is no price competition. The entrance of new firms will press the demand curve DD come the left, wherein it i do not care D1D1 and also is likewise tangent to the LAC curve at suggest G.

At this point, every firms will currently be earning normal profits at price (OP) and also output (OQ). Come note, however, is that OQ is output achieved in the lack of price competition.

The optimum output is OQ1, where excess capacity does not exist as each firm’s demand curve d2d2 is tangent to the LAC at allude H, the lowest feasible point top top the curve under price competition.

However, every firm produces OQ in the absence of price competition. Therefore, output OQ1 signifies excess capacity as result of non-price competition. In the long run, prices and also costs room governed by excess fertile capacity.

Chamberlin suggested that although optimum calculation is better than actual calculation under monopolistic competition, it must not it is in termed as inefficient, however it is the price paid because that product differentiation through the consumer.

He more outlined the the difference between OQ and also OQ1 is a measure up of the cost of product differentiation quite than overfill capacity. Hence, the conditions for optimum output under monopolistic compete are liberty of entry and also non-price competition.

Excess capacity is frequently caused by solved prices, but when prices room flexible, the entry of brand-new firms causes rise in price elasticity the demand, which lowers price and, subsequently, profits. Prices will be much more than costs, and profits are most likely to continue to be at the same level if customer apathy exists.

The level of excess volume is generally dependent on:

Elasticity that demandThe rate of autumn of long-run average cost (LAC)Degree the the preferred product differentiationPresence of price competition

The absence of price competition in between firms has various reasons, as given by Chamberlain and also include the following:

Policy the live and also let liveFormal and also tacit agreementsFear of low price being perceived as identified to low-quality productsProfessional ethicsMasked price cuts in the kind of rebates or free maintenance

These factors often cause excess volume in imperfect markets.

Causes of overabundance Capacity

There are two main causes of excess capacity under monopolistic competition:

1. Downward-sloping demand curve or median revenue (AR) curve

The need curve have the right to only it is in tangential to the LAC once the LAC is falling. Hence, only the horizontal need curve under perfect competition have the right to be tangential come the LAC at its lowest point.

The downward-sloping shape of the need curve is caused by product differentiation. Hence, the greater the elasticity of need for a for sure under monopolistic competition, the much less the excess capacity. Under perfect competition, where need is perfect elastic, over there is no overfill capacity.

2. Entry of brand-new firms in the industry

It also causes excess capacity in the lengthy run, as shown by Chamberlin. Brand-new entrants are attracted through abnormal earnings earned by that company in the quick run.

As firms continue to go into the market, the sector is diminished to earning normal profits. Each firm produces much less than that optimum capacity because of the share of industry demand.

Benefits of excess Capacity

Excess volume under monopolistic vain is caused by product differentiation the leads to product range and quality, i m sorry is valuable to consumers. Consumers typically do not favor homogenous products. Technically, excess capacity increases consumer satisfaction.

Real-World worries on overabundance Capacity

Excess capacity in manufacturing sectors of established economies is caused by demand or it is provided factors. It is mainly attributable to need factors because of reduced demand globally or from home since of company cycles and other demand-induced factors.

However, excess volume can additionally be attributable come supply-side factors such as ongoing rapid development in fixed-asset investment, which boosts manufacturing capacity and crowds the end consumption.

The relationship in between supply and also demand weakens, and also this outcomes in overinvestment and also excess capacity. Common remedies for eliminating excess capacity in the real civilization are together follows:

Boosting domestic need to absorb overabundance capacityBoosting external demand through a global strategyEnforcing environmental and also energy-efficient criter to minimize capacity

How come Monetize overabundance Capacity

Monetizing excess volume is a prudent means of unlocking revenue for the firm, and also it is also good for society. The key strategy is concentrating on non-cash transactions, and also the use of technology. Below is a list of ways to monetize overfill capacity:

Renting out, selling, or commerce excess volume – Amazon’s computing power and also storage are supplied to full capacity during the festive season rush. The remainder of the months, Amazon leas out the computing capability to various other firms and government agencies.Excess office room and industrial machinery can be sold, rented out, or traded come firms. Overabundance industrial tools can it is in traded for much-needed equipment.Excess restaurant food is commonly wasted – through the assist of applications such as Too good To Go, Karma, and YWaste, i m sorry facilitate the revenue of excess restaurant food at lessened prices.
