    1. 1. EC2204- Economics of Enterprise 1: Goals of the Firm
    2. 2. Learning OutcomesUpon completing this section, you should be able to:• Describe the four dimensions to the business environment (PEST).• Illustrate and describe the decision-making process.• Describe the objectives of the firm.• Explain the shareholder wealth maximization model of the firm.• Differentiate between the various theories of profit.• Describe the goals in the not-for-profit sectors of the economy.• Identify the criteria used in estimating expenditures in the public sector.• Calculate profit maximization and cost minimization levels of output for the firm.• Distinguish between economic and accounting cost.
    3. 3. What Is Business Economics?• It deals with the application of microeconomic reasoning to real- world decision-making problems faced by private, public, and not-for-profit institutions.• It extracts from microeconomic theory the concepts and techniques that enable a decision maker to select strategic direction, to allocate efficiently the resources of the organization, and to respond effectively to tactical issues.Economics of Enterprise aims to:• To identify the alternative means of achieving given objective(s), and• To select the alternative that accomplishes the objective(s) in the most resource efficient manner, talking into account the constraints and the likely actions and reactions of interdependent rival decision makers.
    4. 4. The Business Environment (PEST Analysis)• There are generally 4 dimensions to the business environment:1. Political/legal, (P)2. Economic, (E)3. Social/cultural and (S)4. Technological (T)
    5. 5. 1. Political/legal factors (P)• Firms will be directly affected by the actions of government and other political events - These might be major events affecting the whole of the business community, such as the collapse of communism, global banking/financial crisis, the Gulf War or a change of government.• Alternatively, they may be actions affecting just one part of the economy - for example, an anti-smoking campaign by the government will affect the tobacco industry.• Similarly, businesses will be affected by the legal framework in which they operate - Examples include industrial relations legislation, product safety standards, regulations governing pricing in the privatised industries and laws preventing collusion (Anti-thrust) between firms to keep prices up.
    6. 6. 2. Economic factors (E)A firm typically operates a two levels:• The microeconomic environment – which includes the economic factors that are specific to a particular firm operating in its own particular market. Thus one firm may be operating in a highly competitive market, whereas another may not; one firm may be faced by rapidly changing consumer tastes (e.g. a designer clothing manufacturer), while another may be faced with a virtually constant consumer demand (e.g. a potato merchant); one firm may face rapidly rising costs, whereas another may find that costs are constant or falling.• The macroeconomic environment. This is the national and international economic situation in which business as a whole operates. Business in general will fare much better if the economy is growing than if it is in recession. Taxation- corporate tax rate influence FDI, interest rates influence investment and exchange rates have a major impact on firms competiveness especially exporters [€1 = $1.38 Sept 2011]
    7. 7. 3. Social/cultural factors (S)• Social attitudes and values include attitudes towards working conditions and the length of the working day, equal opportunities for different groups of people (whether by ethnicity, gender, physical attributes, etc.), the nature and purity of products, the use and abuse of animals, and images portrayed in advertising.• The social/cultural environment also includes social trends, such as an increase in the average age of the population, or changes in attitudes towards seeking paid employment while bringing up small children.• In recent times, various ethical issues, especially concerning the protection of the environment, have had a big impact on the actions of business and the image that many firms seek to present.
    8. 8. 4. Technological factors (T)• Over the last decade the pace of technological change has quickened leading to a huge impact not only on how firms produce products, but also on how their business is organised.• The use of robots (FIAT factory in Turin) and other forms of computer-controlled production has changed the nature of work for many workers.• It has also created a wide range of new opportunities for businesses, many of which are yet to be realised.• The information-technology revolution is also enabling much more rapid communication (e-mail) and making it possible for many workers to do their job from home or while travelling.
    9. 9. The Firm• The traditional (neoclassical) theory of economics defined the firm as a collection of resources that is transformed into products demanded by consumers.• The costs at which the firm produces are governed by the available technology, and the amount it produces and the prices at which it sells are influenced by the structure of the markets in which it operates.• The difference between the revenue it receives and the costs it incurs is profit - it is the aim of the firm to maximize its profit.
    10. 10. The Decision-Making Model•The ability to make good decisions is the key to successfulmanagerial performance.•In the private sector decisions have to be made on pricing,product choice, cost control, advertising, capital investments,dividend policy etc.•In the not-for-profit sectors decisions must be made on budgetallocation - The Head of College has to make decisions on academic programs,timetabling, computer facilities, number of lectures required etc .•All decision making shares several common elements.•The decision maker must establish or identify the objectives ofthe organization.•The failure to identify organizational objectives correctly canresult in the complete rejection of an otherwise well-conceivedand well-implemented plan.

    12. 12. The Decision-Making Model In 2008, INO took industrial action against the HSE INO objectives Establish Enter talks with HSE1.

    13. 13. Objectives of the FirmAssuming that the objective of the firm is to maximize profits, marginal (incremental) decision rules provide guidelines for making resource-allocation decisions - for example, if marginal cost is defined as the change in total cost resulting from a decision, and if marginal revenue is defined as the change in total revenue resulting from a decision, then any business decision is profitable if one of these results occurs:1. It increases marginal revenue (MR) more than marginal costs (MC), (MR > MC)2. It decreases some MC’s more than it increases others (assuming revenues remain constant).3. It increases some MR’s more than it decreases others (assuming costs remain constant).4. It reduces MC’s more than MR, (MC < MR)
    14. 14. The Shareholder Wealth-Maximization Model• Shareholder wealth is a measure of the value of a firm.• Shareholder wealth is equal to the value of a firms common stock, which, inVturn, is equal to the present value of all future cash returns expected to he generated by the firm for the 0 benefit of its owners. i. V * Shares Outstanding = = (1.1)where V is the current (present) value of a share of stock,π , represents the profits expected in each of the future periods, andke equals the investors required rate of return.i.e. Share Price * No. of Shares issues = Sum of Future Profits/ investors requiredrate of return
    15. 15. The Shareholder Wealth-Maximization ModelAdditional insight regarding the achievement of the shareholder wealth-maximization goal canbe gained by decomposing the profit concept, Π, into its important elements.Profit (π) is equal to total revenue (TR) minus total costs (TQ), π = TR – TC (1.2)Similarly total revenue equals price per unit (P) times the number of units of output sold (Q)or TR = P * Q (1.3)Total cost equals variable cost (VC) times the number of units of output sold (Q) plus fixedcosts (FC) or TC = VC * Q + FC (1.4)By combining equations 1.2, 1.3 and 1.4 with equation 1.1, we getV * Shares Outstanding = (1.5) V * Shares Outstanding = (1.6)
    16. 16. The Role of Profits• Economic profit is the difference between total revenue and total economic cost.• Total revenue is measured as the sales receipts of a firm, that is, price times quantity sold.• The economic cost of any activity may be thought of as the highest valued alternative opportunity that is forgone. - To attract economic resources to some activity, the firm must pay a price for these factors (labour, capital, and natural resources) that is sufficient to convince the owners of these resources to sacrifice other alternatives and commit the resources to this use.• Thus, economic costs may be thought of as opportunity costs, or the costs of attracting a resource from its next best alternative use. - The term economic cost refers to all costs, both explicit and implicit, including a normal return (profit) for owners of the financial resources.
    17. 17. Theories of Profits• The existence of profits determines the type and quantity of goods and services that are produced and sold, as well as the demand for various factors of production—labour, capital, and natural resources.• Because of the important role played by profits in our system, we will review the following theories of profit:1. Risk-Bearing Theory of Profit2. Dynamic Equilibrium (Friction) Theory of Profit3. Monopoly Theory of Profit:4. Innovation Theory of Profit5. Managerial Efficiency Theory of Profit
    18. 18. Risk-Bearing Theory of Profit• Risk-Bearing Theory of Profit is the economic profits above a normal rate of return are necessary to compensate the owners of the firm for the risk they assume when making their investments.• Because a firms share­holders are not entitled to a fixed rate of return on their investment—that is, they are residual claimants to the firms resources—they need to be compensated for this risk in the form of a higher rate of return.• The risk-bearing theory of profits is explained in the context of normal profits, where normal is defined in terms of the relative risk of alternative investments. Normal profits for a high-risk firm, such as a casino operator, should be higher than normal profits for firms of lesser risk, such as water utilities.
    19. 19. Dynamic Equilibrium (Friction) Theory of Profit• All firms should tend to earn a long-run equilibrium normal rate of profit (adjusted for risk).• At any point in time an individual firm or the firms in a specific industry might earn a rate return above or below this long-run normal return level.• This can occur because temporary shocks in various sectors of the economy - For example, firms that produced oil and natural gas experienced a dramatic increase in profits in response to supply shortages following the invasion of Kuwait by Iraq in 1990 a during the general strike in Venezuela in 2002, and also in 2008 (Price of barrel of crude oil in June 2008 = $138). Rates of return rose substantial However, those high returns declined shortly after the war and strike ended, when market conditions led to excess supplies.• Similarly, if a new, inexpensive, and readily available energy source were to be discovered, oil prices would decline substantially - Over time, some producers would leave this increasingly unprofitable market until a normal rate of profit was restored for the remaining firms. The inability of our economic system to adjust instantaneously to changes in market conditions may result in short-term profits above below normal levels.
    20. 20. Monopoly Theory of Profit• In some industries, one firm is effectively able to dominate the market (Guinness in the stout market, Intel in microprocessor industry) and potentially earn above-normal rates of return for a long period time.• This ability to dominate the market may arise from economies of scale (a situation in which one large firm can produce additional units of output at a lower cost than can smaller firms), control of essential natural resources (Bord na Mona), control of critical patents (Pfizer with Viagra) or governmental restrictions that prohibit competition.• The conditions under which monopolist can earn above-normal profits are discussed in depth later.
    21. 21. Innovation Theory of Profit• The innovation theory of profit suggests that above-normal profits are the reward for successful innovations.• Firms that develop unique high-quality products (such as Microsoft in the computer software industry] firms that successfully identify unique market opportunities (such as Federal Express are rewarded with the potential for above- normal profits.• Indeed, the patent system is designed to ensure that these above-normal return opportunities furnish strong incentives for continued innovation.
    22. 22. Managerial Efficiency Theory of Profit• Closely related to the innovation theory the managerial efficiency theory of profit.• This theory maintains that above-normal profits can arise because of the exceptional managerial skills of well-managed firm.• The ability to earn above-normal profits by exercising high- quality managerial skills is a continuing incentive for greater efficiency in any economic system.
    23. 23. Not-For-Profit Sectors• There are 3 characteristics of NFP organizations that distinguish them from for-profit enterprises and influence decision making in the enterprise:1. First, no one possesses a right to receive profit or surpluses in an NFP enterprise. The absence of a profit motive can have a serious impact on the incentive to be efficient.2. NFP enterprises are exempt from taxes on corporate income.3. Many NFP enterprises benefit from the fact that donations to them are tax deductible. These tax benefits give NFP enterprises an advantage when competing with for-profit enterprises.Not-for-profit organizations include performing arts groups, museums, libraries,hospitals, churches, volunteer organizations, cooperatives, credit unions, labourunions, professional societies, foundations-Westgate,
    24. 24. Not-For-Profit ObjectivesFor NFP organizations, such as GOAL, Trocaire, etc. that rely heavily on external contributions, the over-riding objective is to satisfy current and prospective contributors. It is common to find NFP organization that seeks to satisfy its contributors by:(1) Efficiently managing its resources,(2) Increasing its capacity to supply high-quality goods or services and(3) Providing a rewarding work environment for its administrators.
    25. 25. Accounting Versus Economic Costs• Accountants have been primarily concerned with measuring costs for financial reporting purposes. As a result, they define and measure cost by the historical outlay of funds that takes place in the exchange or transformation of a resource.• Economists include some additional costs that are typically not reflected in the cost figures appearing in the financial reports of the firm.• Both the accounting cost and the economic cost of a product will include such explicit costs as labor, raw materials, supplies, rent, interest, and utilities.
    26. 26. Accounting Versus Economic Costs• Economists also include several implicit costs.• The implicit costs consist of the opportunity costs of time and capital that the owner-manager has invested in producing the given quantity of output.• The opportunity cost of the owners time is measured by the most attractive salary or other form of compensation that the owner could have received by operating or managing a similar kind of firm for another investor.• The opportunity cost of the capital employed in producing the given quantity of output is measured by the profit or return that could have been received if the owner had chosen to employ capital in the best alternative investment of comparable risk.
    27. 27. Profit MaximisationSuppose the profit, π, of the ESB can be represented as a function of the output level Q usingthe expression π = -40 + 140Q – 10Q2 we wish to determine the profit maximising level of output for the ESB = 0, Q = 7 How do we know if a maximum or a minimum? , because , we know that a maximum-profit has been obtained Profit is maximised at Q = 7Note: if > 0, if the 2nd derivative is positive, a minimum point is obtained.Calculate the profit at the profit maximising level of output? π = -40 + 140(7) – 10(7)2 π = 450 at Q = 7
    28. 28. Cost MinimisationSuppose the variable costs, VC, of the ESB can be represented as a function of the outputlevel Q using the expression VC = 200Q – 9Q2 + 0.25Q3 FC = 150 TC = 200Q – 9Q2 + 0.25Q3 + 150 we wish to determine the cost minimising level of output for the ESB δTC = 200 – 18Q + 0.75Q2 = Marginal Cost Function δQ δMC = -18 + 1.5Q δQ Q = 12 nd δ 2 MC 2 derivative = 1.5 δQ 2 δ 2 MC because > 0, we know its a minimum cost at Q =12. δQ 2Calculate the total cost at the cost minimising level of output? TC = 200(12) – 9(12)2 + 0.25(12)3 + 150 TC =1,686
    29. 29. Calculating Present and Future Values• The technique of discounting is used to determine the current value of an asset or business. PV = FV / (1 + r) n where PV = Present value, FV = Future value, r = rate of interest, n = number of yearsWhat is the Present Value of an investment that is expected to £500,000 in 5 years if the constant rate of interest over the period is 6%?• The technique of compounding is used to determine the Future value of an asset or business. FV = PV * (1 + r) nwhere PV = Present value, FV = Future value, r = rate of interest, n = number of yearsWhat is the Future Value of a business in 5 years if £500,000 is invested and the constant rate of interest over the period is 6%?It is important to note that this formula can only be used if
    30. 30. Discounting - bringing an amount backwards in time• PV = FV / (1+r)n What is the present value of one million pounds in benefits from a current project that will occur in 10 years if the discount rate of interest is expected to be 4%?• PV = £1,000,000 / (1.04)10• PV = £675,564.17• If average interest rates increase to 6%, how will this affect the outcome?• PV = £1,000,000 / (1.06)10• PV = £558,394.78• (So if Interest rates are higher the PV of a Project or investment is lower)• Implication for Economic Policy – More investment likely if interest rates are lower.
