Chapter 1 the fundamental of managerial economics Managerial economics provides useful insights into every facet of the business and nonbusiness world in which we live-including household decision making. The manager A manager is a person who directs resources to achieve a stated goal. The definition includes all individuals who (1) directs the efforts of others, including those who delegates tasks within organization such as a firm, a family, or a club; (2) purchase inputs to be used in the production of goods and services such as the output of the firm, food for the needy, or shelter for the homeless; or (3) are in charge of making other decisions, such as product cost or quality. A manager generally has responsibility for his or her own actions as well as for the actions of individuals, machines, and other inputs under the manger’s control. Economics Economics is a science of making decisions in a presence of scare resource. Economic decisions thus involve the allocation of scare resources, and a manger’s task is to allocate the scare resources so as to best meet the manager’s goals. Managerial economics defined Managerial economics, therefore, is a study of how to direct scare resource in a way that most efficiently achieves a managerial goal. The key to making sound decisions is to know what information is needed to make an informed decision and then to collect and process the data. The economics of effective management An effective manager must (1) identify goals and constraints; (2) recognize the nature and importance of profits; (3) understand incentives; (4) understand markets; (5) recognize the time value of money; and (6) use marginal analysis. Identify goals and constraints. www.notesolution.com The first step in making sound decision is to have a well-defined goal because achieving different goals entails making different decisions. Decision makers face constraints that affect the ability to achieve a goal. Constraints are an artefact of scarcity. Recognize the nature and importance of profits. Here’s we mean economic profits. Economic profit is the difference between the total revenue and total cost of producing a firm’s goods and services. The opportunity cost of using a resource includes both explicit (or accounting) cost and implicit cost of giving up the best alternative use of resource. The opportunity cost of a good or service generally is higher than accounting cost because it includes both dollar value of cost (accounting cost) and any implicit costs. Economic cost is opportunity cost, it includes both implicit cost and explicit cost. The role of profit By pursuing its self-interest-the goal of maximizing profits-a firm ultimately meets the need of society. Profits signal the owners of resources where the resources are most highly valued by society. By moving scare resources towards the production of goods most valued by society, the total welfare of society is improved.
