Meaning :Is a Discipline that deals with the application of Economic Concepts ,Theories and methods to the practical problem ofthe Business to formulate rational Management decision.Problems may be relating to costs,prices,forecasting the future market,human resource management, profits etc. It is the attempt to optimize business decisions given the firms objectives and given constraints imposed by scarcity.
Scope: Wherever there are scarce resources, managerial economics ensures that managers make effective and efficient decisions concerning customers, suppliers, competitors as well as within an organization.Helps in the following : Demand Analysis and Forecasting : Cost Analysis : Production And Supply Analysis: Pricing Decisions

Why Do Profits among Firms Vary ? Disequilibrium Profit Theories: Markets are sometimes in disequilibrium because of unanticipated changes in demand or cost conditions. Profits are sometimes above or below normal because of factors that prevent instantaneous adjustment to new market conditions. Monopoly profits exist when firms are sheltered from competition by high barriers to entry. Economies of scale, high capital requirements, patents, or import protection, among other factors, enable some firms to build monopoly positions that allow above-normal profits for extended periods. Compensatory Profit Theories: Innovation profit theory, describes the above‑normal profits that arise following successful invention or modernization. As in the case of frictional or disequilibrium profits, innovation profits are susceptible to the onslaught of competition from new and established competitors. Compensatory profit theory describes above‑normal rates of return that reward firms. Superior firms provide goods and services that are better, faster or cheaper than the competition.
ROLE OF BUSINESS IN SOCIETY : Why Firms Exist ? Business contributes significantly to social welfare. These contributions stem directly from the efficiency of business in serving the economic needs of customers. Social Responsibility of Business: The firm can be viewed as a collaborative effort on the part of management, workers, suppliers, and investors on behalf of consumers. Taxes and restrictions on firms are taxes and restrictions on people associated with the firm.

Economic Concepts Demand: Refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between Price and quantity demanded is called as Demand Relationship. Supply: Represents how much the market can offer. The quantity supplied refers to the amount of a certain good producers are willing to supply when receiving a certain price. The correlation between price and how much of a good or service is supplied to the market is known as the supply relationship.
The Law of Demand The law of demand states that, if all other factors remain equal, the higher the price of a good, the less people will demand that good. In other words, the higher the price, the lower the quantity demanded. The amount of a good that buyers purchase at a higher price is less because as the price of a good goes up, so does the opportunity cost of buying that good. As a result, people will naturally avoid buying a product that will force them to forgo the consumption of something else they value more.
Types of Demand: Individual demand: Market demand: Joint demand: Composite demand: Number of Uses. Competitive demand: close substitutes . Derived demand: Variation in demand: Direct demand:
Exceptions to the Law of Demand: Speculative Market: Inferior goods: Increase in Purchasing Power. Prestige goods: Status Attached ( Veblen effect) Price Illusions: Quality related to price. Demonstration effect: Snob Effect: In the Above cases the Demand curve is Upward showing a positive relationship between Price and demand.
Chief Characteristics Of Demand: Inverse Relationship: Price ,an Independent while Demand is Dependant Variable: Other Things remaining Constant: Determinants of Demand: Income: Price: Weather Conditions: Fashion: Money Circulation: Advertisement and salesmanship:
Price Elasticity of Demand Meaning: Definition: (PED or Ed)“ The degree of responsiveness of quantity demanded to a change in price”Formula : Proportionate change in quantity demanded _______________________________________________ Proportionate change in Price
Types of Elasticity of Demand Income Elasticity:Demand for a good is the ratio of the percentage change in the amount spent on the commodity to a percentage change in the consumer’s income. Proportionate change in the quantity purchased _____________________________________________ Proportionate change in Income
Cross Elasticity :A change in the price of one good causes a change in the demand for another. Proportionate change in purchases of commodity X ---------------------------------------------------------------------- Proportionate change in the price of commodity Y Complementary Goods: Substitutes:
Perfectly Elastic Demand: Where No Reduction In price is Needed to Increase Demand.Perfectly Inelastic Demand: Where Change in Demand results in no change in price .Demand with Unity Elasticity: Equal ChangeRelatively Elastic Demand: Reduction in price leads to relatively more change in demand.Relatively inelastic Demand: Where reduction in price leads to less change in demand.
Determinants Of PED Availability of substitute goods: Income: Necessity: Brand loyalty: Who pays: Proportionate of Income spend:
Opportunity Cost:Is meant the sacrifice of alternatives required by that decision.Ex: Funds, Time. Production functionIs a function that specifies the output of a firm, an industry, or an entire economy for all combinations of inputsQ = f(X1,X2,X3,...,Xn)where:Q = quantity of outputX1,X2,X3,...,Xn = quantities of factor inputs (such as capital, labour, land or raw materials)
The law of supply This Law demonstrates the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases revenue.Factors Effecting Supply: Input prices – Technology - Expectations -
Law of Demand The Law of Demand A, B and C are points on the demand curve. Each point on the curve reflects a direct correlationbetween quantity demanded (Q) and price (P).So, at point A, the quantity demanded will be Q1 and the price will be P1, and so on. The demandrelationship curve illustrates the negative relationship between price and quantity demanded.The higher the price of a good the lower the quantity demanded (A), and the lower the price, themore the good will be in demand (C)
Law of Supply Supply (s) P3 Supply Relationship P2 P1 Q1 Q2 Q3A, B and C are points on the supply curve. Each point on the curve reflects a direct correlationbetween quantity supplied (Q) and price (P). At point B, the quantity supplied will be Q2 and the pricewill be P2, and so on

Pricing Methods:1. Cost + Pricing methods: Advantages of cost-plus pricing : Easy to calculate. Minimal information requirements. Easy to administer. Ethical advantages. Simplicity. It is readily available. Price increases can be justified in terms of cost increases .
Disadvantages : Provides no incentive for efficiency. Tends to ignore the role of consumers. Tends to ignore the role of competitors. Ignores Opportunity costs.
2.Target rate of return pricing :3. Value-based pricing: Important concepts: Customers are value conscious rather than price conscious e.g. some customers will pay extra for prompt delivery. Customers assign a personal value to a product or service e.g. a teenager is willing to pay a premium price for a concert performed by his idol. The selling price is based on customers’ perceived value rather than on the vendor’s costs.
