Topic: “Elasticity of Demand and Managerial Decision Making”

The demand of a commodity depends on the size of the total market or industry demand for the commodity which in turn is the sum of demands for the commodity of the individual consumers in the market.
The demand for a commodity arises from the consumers’ willingness and ability to purchase the commodity. Consumer Demand Theory postulates that the quantity demanded of a commodity is a function of the price of the commodity, the consumers’ income, the price of the complementary and substitute commodities and the taste of the consumer.
It is also expressed as:
Qdx=f(Px, I, Py, T)
Where
Qdx = Quantity demanded of the commodity X by an individual per time period
Px = Price per unity of commodity Y
I = Consumer income
Py = Price of substitute or complementary commodity
T = Consumer taste

When the firm increases the price of a commodity, sales generally decline. A manager expects an inverse relationship between the quantity demanded of a commodity and its price. On the other hand, when a consumer’s income rises, he/ she usually purchases more of most commodities, known as normal goods. There are some goods and services, however, which the consumer purchases less as income increases, which are termed as inferior goods.
The inverse relationship between the price and the quantity demanded of the commodity per time period is the individual’s demand schedule for the commodity, and the plot of data gives the corresponding individual’s demand curve. The inverse relationship between the price of the commodity and the quantity demanded per time period is referred to as law of demand.
The responsiveness in the quantity demanded of a commodity to a change in its price could be measured by the inverse of the slope of the demand curve.
The price elasticity of a demand (Ep) is given by the…...

Economic Decision Making

...Economic Decision Making Renice Taylor ECO/212 Monday, February 14, 2011 Anusuya Chatterjee Economic Decision Making Today, every individual must make a decision in his or her lifetime. However, every individual does not make decisions in the same manner. In economics, there are four major principles of decision-making: “people face trade-offs”, “the cost of something is what you give up to get it”, “rational people think at the margin”, and “people respond to incentives” (Ten Principles, n.d., pgs. 4-7). “People face trade-offs” is simply the concept of giving up one thing that we like for another. “The cost of something is what you give up to get it” means that cost will always be a factor. However, it should not be the only one. “Rational people think at the margin” refers to individuals thinking in shades of gray. “People respond to incentives” deals with the majority of middle-class citizens. Many individuals will hold on to their money until a sale comes along. Recently, my husband and I were in the process of deciding whether to lease a new sports utility vehicle or finance an older one. The benefits of leasing will be driving a new vehicle. There are no worries of damage done with the previous owner, accidents, etc. However, after looking at the marginal......

Managerial Decision-Making

...describe the concept of managerial decision-making. It will look specifically at the ‘Rational Decision-Making Model’, exploring the shortcomings of this approach, and will suggest possible ways a manager could overcome these issues when striving to make a rational decision that will bring benefit to an organisation. Throughout this essay, empirical research and examples from academic literature will be presented to illustrate the discussion. Decision-making is arguably the single most important process in an organisation, being a basic task at all managerial levels. (Heraclious 1994) Rational Decision Making can be defined as choices that are consistent and value maximising within specified constraints. (Bergman, Coulter, Robbins & Stagg 2008) The ‘Rational Decision-Making Model’ is a structured process for essentially making a logically sound decision. The model is made up of a series of steps, with the details often varying, but generally including; recognition of the decision requirement, diagnosis and analysis of causes, development of alternatives, selection of alternative, implementation, evaluation and feedback. (Heraclious 1994) A person making a rational decision would be logical, fully objective, and would strive to select an alternative that maximises the likelihood of achieving their goal. (Bergman, Coulter, Robbins & Stagg 2008) There are a number of issues surrounding the effectiveness of the model for rational decision-making, and there has been......

Making Economic Decisions

...Making Economic Decisions Econ/212 Making Economic Decisions Individuals make decisions based on three principles. To understand the decision-making principles individuals must first realize that people have limited resources and unlimited wants. Because individuals face scarcity, the first economic principle is that people are rational. The principle of rationality means, “Individuals and firms use all information available to making decisions” (Hubbard & O'Brien, 2010). The second principle of decision-making is that people respond to incentives. This means that people are more likely to make a certain choice if they will receive a benefit from making the choice. Last, most decisions are made at the margin. This means that most decisions are not all or nothing, but rather involve doing more on one thing and less of another. When making the decision to return to school to attain a bachelor’s degree, the marginal benefits and the marginal cost of the decision has to be considered before the final decision could be made. The marginal benefits of returning to schools were the additional income that I would be able to receive from the higher degree, the satisfaction that I would receive from achieving a degree, and the ability to find a job that used more accounting skills. The marginal cost of the decision to return to schools were the decrease in income that I would face by having less time to work, the stress of returning to school and juggling other......

...sort of panacea for bacterial infections that used to kill millions of people every year, are losing their ability to thwart disease. This means that, if the present trend continues, humanity will once again find itself facing the kinds of apocalyptic epidemics that have been man’s curse for all but the last century of history. Bacteria of many ilk, from the relatively innocuous streptococci that give most people a sore throat and a bit of fever, through the often lethal and fast-propagating tuberculosis and e.choli, are becoming resistant to antibiotic treatment. And while many bacterial infections will simply run their course, causing considerable but temporary suffering, others will kill their hosts, or develop a symbiotic relationship, making the human host a perpetual propagator of lethal disease. Here’s the shocking fact: We are the ones creating these super bacteria. While evolution plays a role, we are helping it to strengthen mankind’s number one living enemy. The evolutionary part is simply that some bacteria do survive antibiotic treatment and its drug-resistant genetic material gets passed on to other bacteria. It is precisely because of this that health authorities in developed countries urge us to consume all the pills in a prescription: While we may feel better after a few pills have killed most sieging bacteria, the few that are left behind due to an incomplete treatment are likely to be the strongest, most resistant ones. That batch may lay dormant waiting......

Steve Job was a great entrepreneur, who had follow hub-and-wheel management approach to organize a multinational corporation; on the other hand, Tim Cook is more cooperative than Steve Job and follows the management theory of Taylor’s scientific approach and theory of the human relations approach (Finkelstein, 2013).     Although the management approach of Steve cannot be questioned but he was demanding and aggressive and handled all the planning and decision making processes through a decentralized structure, as his approaches was based on theory of Fayol, as per that manager plans, organizes, commands, co-ordinates and controls all the activities and processes (Adetule, 2011).

Managerial Decision-Making Process

... Mitya, 09/14/2015 Managerial decision-making process. Bias. I was a product manager in my German-Polish company in 2009. The company was supplying building materials to the Polish market. Due to non-satisfactory financial results caused by the financial crisis in 2008 I was instructed by my General Director to increase the sales volume of my product portfolio up to 50% by the end of 2010. The product set consisted of aluminum composite panels, building aluminum profiles, and polycarbonate panels. I made a decision to relocate production lines of aluminum profiles from Germany to Poland by using one of our partners’ plants. My decision was based on the largest aluminum trade margin that allowed me to pursue a more flexible pricing policy. As a consequence, it could lead to increased levels of demand at the local market. At the same time simplicity and low cost of tech manufacturing process made this solution less financially risky in case of my managerial decision failure. My product portfolio did not have another alternative that would help me to increase my turnover index up 50% within 1 year. Therefore, I had no other alternatives except for moving the production line to the local Polish market. Plus, it could provide me with factually reduced cost per unit, cost of logistics and, as a consequence, an increase in sales. Back then I followed the exact rational model of decision making process. I conducted a thorough marketing research project. In 2009, I visited all our 20...

...Economics Decision-Making Process Name Institution Economics Decision- Making Process According to (Anderson & Sweeney, 2000) managers and economists use the decision-making process to analyze economic models. Decision-making process involves selection of the best alternative from many choices. It involves setting goals to make decisions, assessing alternative occupations and gathering information. When analyzing economic models, managers and economists note that there are fundamental assumptions that every model relies on to remain valid. These assumptions are present in all decision circumstances. Everyone in the society, from the small business owner to the billionaire investing in the real estate to the teenager applying a job makes some economic decisions at some point. The basic assumptions are surrounding decision-making process always apply. The primary factors surrounding economic decision making include; maximizing value, working on a budget, cost benefits analysis and rational decision making. The process of making economic decisions is complex as that of consumer decision making. When making decisions, businesses derive most of the critical choices from macroeconomics data, any of the choice made could mean the failure or success of their enterprise. The accuracy, reliability and validity of the information the business uses are of great importance (Tremmel, 2008). My aim in this paper, therefore, is to discuss and identify any decision-making......

Making Economic Decision

...Decision Making in Economic Issues Economics is all about how to manage the limited resources in the society. Resources are scarce; if there could be unlimited resources then there could not be economics issues. So, the study of how society manages their scarce resources is Economics. In other word, the essence of economics is to acknowledge the reality of scarcity and then figure out how to organize society in a way that produces the most efficient use of resources. People need to take right decision in right time. So, how people make economic decisions regarding their buying goods or services at the market, are ruled by four basic principles. They are: 1. People face tradeoffs All decisions involve tradeoffs. Examples: * Going to a party the night before your midterm leaves less time for studying. * Having more money to buy stuff requires working longer hours, which leaves less time for leisure. * Protecting the environment requires resources that could otherwise be used to produce consumer goods. 2. The cost of something is what you give up to get it. * The opportunity cost of any item is whatever must be given up to obtain it (the biggest cost of one of your alternative options). * Making decisions requires comparing the costs and benefits of alternative choices. * It is the relevant cost for decision making. 3. Rational People think at the margin Systematically and purposefully they can do the best to achieve their objectives. The......

Strategy Simulation Game: Economics for Managerial Decision Making

...Introduction This review paper shines a light on how vital the use of economic tools is in making managerial decisions as reflected in the simulation. Decision making process of management is described in different market structures. Just as it pertains to any for-profit business organization, the goal is to cut and maximize profits in each type of market structure. Based on the information provided in the simulation, Quasar Computers were involved in an extensive research in developing a pioneer product “the Optical Notebook.” In 2003, the company launched the first all-optical notebook computer and branded it the “Neutron”. This product is described as an energy saving optical technology with its rechargeable batteries capable of lasting up to three days; hence, transcending it into a leading technological product in its unique class. With the assistance of senior executives in the company, the decisions on operational and business strategies relative to a variety of market conditions are taken and discussed. Monopoly Quasar emerged as the only player in the market for its unique optical notebook computer; therefore, establishing a monopoly market structure. Within this monopolist market structure, maximizing profit tends to occur at the point where marginal cost equals marginal revenue based on the result shown by toggling the demand curve. In the initial scenario, it was presented that Quasar had the patent rights on all-optical technology for three years from the......

Economics Decision Making

...Economic Decision Making Eco/ 212 July 4, 2010 This paper will list and review the four principles of individual decision making. The listed principles are necessary tools each consumer needs in order to make the best informed decision one can regarding his or her needs. Today’s consumers are faced with a constant barrage of financial decisions that today’s economy requires we make. Most consumers today are true economist whether they know it or not. Although many may not realize it, we all make decisions based on the four principles of economics which are: the cost, the incentive, the trade-off, and the margin. Economics is the study of how a society manages the scarce resources it has. When a consumer decides to make a purchase the first principle comes into play, how much will the item cost. The second principle, at least for me, becomes what are the incentives to make the purchase. The third principle for economic decision making is what would be the trade-off for the purchase. A consumer would now begin to question what item or goal would have to be given up or set aside to gain this particular item or goal. The fourth principle is known as the margin. The benefit of an item (marginal benefit) should carry more weight than the cost of an item (marginal cost). Because the benefits should outweigh the cost, this would give the consumer the final margin. Do keep in mind opportunity as well as price, availability, upkeep, re-sale value, and the potential...

First leadership as an organizations or group phenomenon is observed as a set of role behaviors on the part of an individual (called the ‘leader’) when there is a need for influencing and coordinating activities of group members to achieve a common goal. As Cartwright and Zander ( 1968 ), pointed out, leadership consists of such actions as “setting group goals, moving the group toward its goals, improving the quality of the interactions among the members, building cohesiveness of the group, and making resources available to the group” (p. 304). Such actions are learned and volitional acts on the part of a leader, and therefore can be acquired through training. Second, leadership is both a relational and an attribution phenomenon. The existence of a leader depends upon the existence of one or more followers and the kind of status or power relationship that develops between them. It is the followers' perceptions of a leader's behavior, their acceptance of his or her influence attempts and the subsequent attribution of leadership status to the individual that give rise to the phenomenon, (Beckhard, 1996). Without followers' perceptions, acceptance and attributions, the phenomenon would simply cease to exist. Hence, leadership is......

Economics for Decision-Making

...500B Economics for Decision-making Final Research Paper: Oil industry Forecast Background The United States is one of the largest oil reserves’ country in the world. And its proven oil reserves was 227 billion barrels, ranked 11 in the world. More than 80 percent of the country's oil reserves are concentrated in four states: Texas (24 percent), Alaska (22 percent), Louisiana State (20 percent) and California (19%). Today, the oil industry is the largest industry in the world and accounts for over $3 trillion dollars in annual sales. Between 1950 and 1973 the world oil industry grew 9-fold – a rate of increase of 10% per year, sustained over a period of 20 years. During that time period, the world produced over 2.5 billion new motor vehicles, half of which in the United States. The five largest producers of oil are Saudi Arabia (10.37 mbd), Russia (9.27), United States (8.69), Iran (4.09) and Mexico (3.86). And now, International instability and rising demand have severely impacted prices, which reached an all-time high of over $70 per barrel earlier this year. Both domestic and foreign oil producers are relishing in high prices by posting record profits. The growing trade imbalance in favor of oil producing nations jeopardizes American long-term economic health. The current level of US national debt – $8.3 trillion – coupled with the Iraq War places the US in an extremely vulnerable position. Finally, unmentioned as of yet, is the rising threat of global......
