Managerial economics is a branch of economics involving the application of economic methods in the managerial decision-making process. Economics is the study of the production, distribution and consumption of goods and services. Managerial economics involves the use of economic theories and principles to make decisions regarding the allocation of scarce resources.
Managers use economic frameworks in order to optimise profits, resource allocation and the overall output of the firm, whilst improving efficiency and minimising unproductive activities. These frameworks assist organisations to make rational, progressive decisions, by analysing practical problems at both micro and macroeconomic levels. Managerial decisions involve forecasting (making decisions about the future), which involve levels of risk and uncertainty, however, the assistance of managerial economic techniques aid in informing managers in these decisions.
The two main purposes of managerial economics are:
The core principles that managerial economist use to achieve the above purposes are:
In order to optimize economic decisions, the use of operations research, mathematical programming, strategic decision making, game theory and other computational methods are often involved. The methods listed above are typically used for making quantitate decisions by data analysis techniques.
The theory of Managerial Economics includes a focus on; incentives, business organization, biases, advertising, innovation, uncertainty, pricing, analytics, and competition. In other words, managerial economics is a combination of economics and managerial theory. It helps the manager in decision-making and acts as a link between practice and theory. Furthermore, managerial economics provides the device and techniques for managers to make the best possible decisions for any scenario.
Some examples of the types of problems that the tools provided by managerial economics can answer are:
Managerial economics is sometimes referred to as business economics and is a branch of economics that applies microeconomic analysis to decision methods of businesses or other management units to assist managers to make a wide array of multifaceted decisions. The calculation and quantitative analysis draws heavily from techniques such as regression analysis, correlation and calculus.
Microeconomics is the dominant focus behind managerial economics, some of the key aspects include:
The law of supply and demand describes the relationship between producers and consumers of a product. The law suggests that price set by the producer and quantity demanded by a consumer are inversely proportional, meaning an increase in the price set is met by a reduction in demand by the consumer. The law further describes that sellers will provide a large quantity of the good if it sells at a high price.
Excess demand exists when the quantity of a good demanded is greater than the quantity supplied. Where there is excess demand, sellers can benefit by increasing the price. The converse applies to excess supply.
Production theory describes the quantity of a good a business chooses to produce due to multiple factors. These factors include; raw material inputs, labor, machinery costs, capital, etc. The production theory states that a business will strive to employ the cheapest combination of inputs to produce the quantity demanded. The production function can be described by the function where Q denotes production from a firm, L is the variable inputs, and K is the fixed inputs.
The opportunity cost details the costs and benefits of each action the business is considering pursuing, and the cost of choosing one activity over another. The decision-maker is then in the position to choose the action with the highest payoff.
The principle uses the conjecture of supply and demand to set an accurate price for a good. The aim of the price theory is to allocate a price for a good such that the supply of a good is met with equal demand for the product. If a manager sets a price to high for the good, the consumer may think it is not worth the cost and decide not to purchase the good, hence creating an excess in supply. The opposite occurs when the price is set too low, this causes demand for a good to be larger than the supply.
Capital is the most critical factor in an enterprise, this theory prevails in the rational allocation of funds and decisions of organizations to invest in profitable projects or enterprises in order to improve the efficiency of organizations. The rational allocation of funds may include acquiring business, investing in equipment, whether investment will improve the business at all.
The elasticity of demand is a prominent concept in managerial economics. Alfred Marshall in his own words described elasticity of demand as ‘The elasticity of demand in a market is great or small according to as the amount demanded increases much or little for a given fall in price and diminish much or little for a given rise in price.
The microeconomic principles are useful principles for managers to make decisions, Managerial economics entails the use of all of these analysis tools to make informed business decisions.
The price elasticity of demand is a highly useful tool in managerial economics as it provides managers with the predicted change in demand associated with an increase in the price charged for its goods and services. The price elasticity principle also outlines the changes in demand for goods with changes in the income of a populous.
Where is the change in demand for the respective change in price , with Q and P representing the quantity and price of good before a change was made. The price elasticity is important for managerial economics as it aids in the optimization of marginal revenue of firms.
In economics, margin is the change in revenue and cost by producing one extra unit of output. Both the marginal cost and marginal revenue are extremely important in marginal economics as profit of a firm is maximized when the marginal cost is equal to the marginal revenue. Managers can make business decisions on the output level based on the analysis, in order to maximize profit of the firm.
In the development of economics and management, more and more econometric analysis methods are applied. The use of differential calculus is a powerful tool in managerial economics.
By taking the derivative of a function the maximum and minimum values of the function are very easily determined by setting the derivative equal to zero, an example of this is finding a quantity of production that maximizes the profit of the firm. This concept is important for managers to understand in order to minimize costs or maximize profits.
The main applications of mathematical models:
Managerial economics to a certain degree is prescriptive in nature as it suggests a course of action to a managerial problem. Managerial economics aims to provide the tools and techniques to make informed decisions to maximize the profits and minimize the losses of a firm. Managerial economics has use in many different business applications, although the most common areas of its focus are in relation to the Risk, Pricing, Production and Capital decisions a manager makes.
The decision making steps, which are guided by the tools of managerial economics, include;
It is important to understand what pricing decisions should be made regarding the products and services of the firm, as efficient pricing is required to maintain desired levels of revenue and profit, whilst also maintaining customer satisfaction. Setting a price too low reduces profitability, negatively affects the perceived quality of the product, and sets an expectation of price for the consumer. Setting a price too high may negatively affect the image of an organisation from the perspective of the consumer.
Managers may price using intuitive or technocratic decision-making styles. A technocratic approach relies on quantitative analysis and optimisation, and typically involves a compensatory method of evaluation. Compensatory evaluation allows one attribute to compensate for another attribute. For example, a manager may price a product at a lower price to compensate for its lower quality. Intuitive decision-making relies on consumer heuristics, defined as cognitive processes of fast decision-making, which occur by limiting the amount of information analysed.
Economic concepts such as competitive advantage, market segmentation, and price discrimination are relevant to pricing strategy. In order to set a price that drives sales and firm performance, managers must understand the economic environment in which they are operating.
Price discrimination involves selling the same good at different prices to different consumer segments. Consumer segments are separated by a significant variation in the amount they are willing to pay. In order for price discrimination to occur, organisations must be able to separate customer segments so that consumers are not aware of price differences.
In order to successfully make organisational decisions, management must have an understanding of consumer behaviour and decision-making. Consumer behaviour relates to buying, using and selling goods, services, time and ideas by decision-making units.
Rational Choice Theory is a decision-making theory, also known as the law-and-economics theory, which applies the assumption that people will try and maximise their outcomes, have well-defined preferences and are consistently rational decision-makers. This theory develops on the Economic Man Theory, which assumed that people respond to stimuli (external factors) to generate a response (outcome). Rational Choice Theory builds on this theory by understanding that the consumer is an information processing decision-maker, however it fails to incorporate psychological literature and empirical findings on the psychology of human-behaviour.
Rational Choice Theory makes the following assumptions:
These assumptions do not account for circumstances of human error where consumers misinterpret information, or only consider portions of relevant information. The assumption of rational choice theory that when provided with all the required information, consumers will make a rational decision is limited.
Consumer preferences depend on the state the consumer is in when making the decision. Simple examples of states influencing decision making are food tasting better when you are hungry or going being more enjoyable when not sick. Most models of state-dependant preferences make the assumption that people are aware of the influence of their particular state on the preferences they are making in that moment, however empirical studies suggest this is not always true.
Projection bias occurs when consumers predict that their future tastes will represent their current tastes.
Attribution bias occurs when consumers consider past experiences in deciding whether to repeat a previously performed consumption activity. This bias can lead to systematic errors in economic decisions.
Cognitive bias, or status quo bias, occurs when consumers would rather follow previous procedures, or buy previously used products, without evidence that this choice is better than alternatives. This bias opposes the basic law of human nature, that the most adaptable species is the one to survive, and is in opposition with positive views on change expressed in business literature. Cognitive bias can cause interference with the effectiveness of public policies and successful application of relevant policies and choices.
Monetary and non-monetary incentives are used by managers to motivate employees to achieve results aligned with firms' objectives. The outcome of incentives depends on the design and the implementation process of the incentives, their interaction with intrinsic and social motivations, and the behavioural effects of their removal.
In a field experiment analyzing the effects of performance-based monetary incentives, it was shown that productivity improved in line with employees' ability, however there was an increase in neglect of non-incentivised tasks.
Monetary incentives generally have two kinds of effects, known as the standard direct price effect, and the indirect psychological effect. Standard direct price effect makes incentivised behavior more attractive; and the indirect psychological effect makes incentivised behavior less appealing, due to incentives containing information relayed from the principal (manager) to the agent (worker), which can provoke unexpected behavioural outcomes.
Agents receive information from both the size and existence of incentives. For example, offering members of the community high monetary compensation to be in the presence of a nuclear waste site, indicates that there are high risks involved with the plant, making community members less willing to accept the plant even in the presence of monetary incentives. Contrarily, in an experiment, a childcare introduced a fee of $3 for parents who picked their children up late. The information conveyed to the parents from this incentive was that the small fine indicated being late is not too bad, and in the short run the number of late pick-ups increased. This information persisted when the fee was removed, and parents who had experienced the fine were more likely to pick their child up late than those who had not received the information given by the incentive.
As a general rule however, where incentives are high enough, the standard direct price effect tends to take precedence over the indirect psychological effect, unless incentives are so high that agents form a negative inference of the circumstances.
Where workers are paid at a substantially lower rate to their peers, outputs and attendance can fall out of alignment with organisational objectives. Pay disparity can cause harm to an organisations social culture, cohesion and cooperation, and alter the workplace dynamic significantly. In developing countries where social interactions are heavily relied upon for economic activity, these effects are particularly undesirable. It has been proven that these consequences can be avoided by clearly justifying pay inequality to workers. Potentially due to self-serving bias, workers are unwilling to believe that they perform at a lower standard than their peers unless shown undeniable evidence. Particularly in settings where employees do not trust their managers, workers may be inclined to suspect favouritism until they are given evidence and justifications.
Tournament theory is used to describe why different pay levels exist between different roles in the business hierarchy. The idea of tournament theory is that agents who put in effort to achieve promotions are rewarded with a higher, non-incremental, pay rate. The reward of a higher pay rate incentivizes behavior that leads to promotions. This behavior is often lucrative and therefore ideal for the business. Tournaments can be very powerful at incentivizing performance. Empirical research in economics and managements have shown that tournament-like incentive structure increases the individual performance or workers and managers in the workplace.
Demand forecasting assists management in predicting future sales, which informs operations decisions, marketing decisions, and allows revenue projection to occur, which assists the firm in future financial planning. The process of demand forecasting often uses business analytics, particularly predictive analytics, with respect to historical data and other analytical information to make an accurate estimation. For example, using an estimate of a firm's capital expenditure and cash flow, managers can create forecasts which assist in financial planning and improve the financial health of the firm.
Effective demand management considers factors which are both within and without the firms control, such as disposable income, competition, price, advertising and customer service.
Consumer choice is highly influential on demand analysis, as each consumer aims to maximise their satisfaction with a combination of goods and services, subject to the limitation of funds available.
Production costs directly affects a firm's profitability. Managerial economics involves identifying the out put level for a firm, with respect to minimizing the production cost, where marginal cost equals marginal revenue, in order to maximize its profit. Most common types of costs:
Profitability management is understanding what makes a firm profitable, and what can be done to improve its profitability. It integrates finance and sales, and aims to optimize sales revenue and marginal cost of the firm. Profit management is technology enabled, as firms must be quick to respond to rapid changing market and to know the true economic cost of its products and services. Management needs to drive cooperation between different functions of the firm such as sales, marketing, and finance, to ensure the teams recognize the importance of coordinated effort. Proper planning and profitability management is key to good business management.
Capital management is the planning, monitoring, and controlling of the assets and liabilities of a firm, particularly, in an effort to maintain cash flow to meet the firm's short-term and long-term financial obligations. Proper capital management is important to the financial health of a firm, with efficient resource allocation through capital management, firms can improve its cash flow and profitability. Capital management involves tracking various ratios within the firm, most important ones include:
Rate of return and cost of capital (i.e. interest rate) are important factors of capital management.
When making decisions, managerial economics is used to analyze the micro and macroeconomic environments relating to an organization. Microeconomics considers the actions of individual firms surrounding utility maximization, whereas in comparison, Macroeconomics considers the actions and behaviour of the economy as a whole. As such, both area of economics have influence in the development of managerial economics frameworks.
With regard to macroeconomic trends, the forecasting and analysis of areas such as output, unemployment, inflation and societal issues are essential in managerial economics. This is because these areas in the macroeconomy have the ability to provide an overview of global market conditions, which can be imperative for managers to understand. An example of managerial economics using macroeconomic principles is a manager choosing to hire new staff rather than training old ones in a time where the rate of unemployment is high, as the possible talent pool would be very large. The political structure of a country (whether authoritarian or democratic), political stability and attitudes towards the private sector can also affect the growth and development of organizations. This can be seen through the influence different government policies can have on management quality. In particular, policies around product market competition has been seen to significantly impact collective management practices in countries by either reducing or supporting poorly managed firms. A clear understanding of relevant markets and their different conditions is a vital task for a managerial economist, as even with market instability and fluctuations the goal is to always steer the company to profits.
Microeconomics is closely related to Managerial economics through areas such as; consumer demand and supply, opportunity cost, revenue creation and cost minimization. Managerial economics inculcates the application of microeconomics application and makes use of economic theories and methods in analyzing a business and its management. Moreover, managerial economics combines economic tool and technique to solve the managerial problems.
Microeconomics also gives indication on the most effective allocation of resources the business has available to it. These microeconomic theories and considerations are used via managerial economics to make decisions regarding the business. By understanding the principles of microeconomics, managers can be well informed to make accurate decisions regarding the form.
An example of managerial economics using microeconomic principles is the decision of a manager to increase the price of the goods being sold. A manager should evaluate the price elasticity of the product to equate the respective demand of the product after the price change.
From a management perspective, managerial economics techniques are useful in many areas regarding business decision-making, most commonly including:
At its core managerial economics is a decision-making process, by taking two or more options and optimizing a business decision while considering fixed resources to the function.
