Principles of Microeconomics: First Homework

Subject 1: Introduction

1.Keynes’s Fallacy of Composition states that although economic policies may be good for one system, they could be harmful when applied to a different system. An example would be an individual saving money. It would be beneficial to the individual, because he wouldn’t spend all of their income, however it would be bad for the economy since there wouldn’t be money being re-infused. Macroeconomics looks at the behavior of economic aggregates on a national scale (aggregate, GDP). Microeconomics looks at the behavior of individual decision-making, and examines the economic activities of individual consumers and producers (households and business firms).

Subject 2: Demand, Supply, and Market Equilibrium

3. The Law of Demand states that there is an inverse relationship between price and quantity demanded. The main objective for consumer demand is to maximize utility, which is satisfying power. Therefore the consumer would like to pay the lowest price.

4. There are five determinants for consumer demand: taste, income, and price, prices of substitutes and complements, and future expectations. If you have a taste for a certain product, you are more likely to buy more. If you have a low income, you may not be able to buy an expensive product. Also, if a product of a substitute is cheaper, consumers may switch to a new product. Finally, future expectations may influence a consumers demand for a certain product because if it will be cheaper in the future, they may hold off on buying it until the price goes down.

5. Substitutes are goods that can serve as alternatives for one another. When the price of one increases; demand for the other increases. An example would be Pizza Hut and Dominos Pizza. Complements are goods that go together, a decrease in the price of one would result

...Costs of Going to School Melissa Olson Rasmussen College Author Note: This paper is being submitted for Professor Sherwood’s G204 Microeconomics course. Costs of Going to School I had a good idea of what I was getting into when I signed up for classes at Rasmussen. I knew that I wanted to pursue a career in accounting, and in order to do that, I would need to complete schooling and get some sort of degree. When deciding the path I wanted to take, Rasmussen was one of my options. The thing that I liked most about Rasmussen was the flexibility of their online courses. Most people who took them still worked full time jobs and some even had families of their own to take care of. I knew that since I still needed to work full time in order to make student loan payments, that Rasmussen was my best bet. I signed up for courses, and began to look at the accelerated schedules. The reason that I chose this path was because I knew that I could handle a big workload and could take on up to six courses per quarter. The graduation date was also much sooner than if I were to take the regular scheduled courses. I knew there would be late nights, busy weeks, and a hectic finals week, but I also knew that I could handle it. Some of the specific opportunity costs that I have faced since starting my school career are less ‘free’ nights. I try to spread my schoolwork out evenly, so I don’t get too overwhelmed when it comes closer to my assignment due dates. There have been nights where...

Revenue Management

...Decision Sciences HOMEWORK: REVENUE MANAGEMENT BY A RENTAL CAR COMPANY:1 You are a consultant hired by a major national rental car company that is seeking to improve its pricing strategy. In particular, it is considering adopting a strategy of customized pricing tailored to the underlying micro-markets that it might face. In the rental car business (as in the hotel and resort business), price customization is known as revenue management. As a test case, your client is considering a pricing experiment at Lambert Airport in St. Louis, Missouri, a location at which your client has dominant market share and thus can safely ignore possible reactions of competitors. Careful market research has revealed that the St. Louis market is composed of two micromarkets. The first comprises business travelers; the second comprises vacation travelers. The demand curves for these two micro-markets are given below: Micro-market Business travelers Vacation travelers Demand curve equation Q1= 3,600 – 20P Q2= 3,000 – 30P In the table above, P is the daily rental rate, while Q1 and Q2 are the numbers of vehicles rented per day by business travelers and vacation travelers, respectively. Like airlines, the rental car business is one in which the marginal cost of serving an extra customer is nearly zero. For this reason, throughout this exercise, we will assume that your client’s MC = 0. (Of course, your client has fixed costs, but as an astute practitioner of microeconomics, you know that these...

...Long-Term Investment Decisions Tiffant Lewis Strayer University Dr. Xiaodong Wu ECO 550 March 9, 2014 Introduction One of the most important long term decisions for any business relates to investment. Investment is the purchase or creation of assets with the objective of making gains in the future. Typically investment involves using financial resources to purchase a machine/building or other asset, which will then yield returns to an organization over a period of time. Planning investments involves thinking about a range of issues that have a bearing on where you ultimately decide to put your money. These issues will vary according to your particular age, circumstances and attitude to risk, and thinking about them carefully before you start making commitments will help you avoid some potentially costly mistakes. 1.

...Homework Practice Questions: Microeconomics/Macroeconomics The following questions are for homework practice only. They are to be answered in detail, so it can be used for practice and future reference. 1. Suppose you are hired to manage a small manufacturing facility that produces Widgets.  (a.) You know from data collected on the Widget Market that market demand and market supply have both increased recently. As manager of the facility, what decisions should you make regarding production levels and pricing for your Widget facility? The increase in supply is likely the result of the increased demand, which created economic profit for firms because of higher prices. Depending on whether the increase in supply has expanded sufficiently to causes prices to fall and economic profits to disappear, your firm could profit by expanding output and increasing prices. This can be determined by seeing if prices are higher than they were before the increase in demand. The price per unit tells you the marginal revenue per unit sold. Output decisions should then be based on setting output so that marginal cost is equal to marginal revenue. In this case, the manager would increase the supply and price; but is should increase both in a controlled environment so that the total revenue profits does not drop (for example, raising price beyond a certain price might decrease the demand thus reducing overall profit) Also, the supply should be increased so that Marginal Cost< Marginal...

...INTRODUCTION There is little doubt that no two people study the same way, and it is a near certainty that what works for one person may not work for another. However, there are some general techniques that seem to produce good results. So I decided to concentrate on working for this research because it’s very important for the readers to read this so that they have to step up in learning styles. My purpose of doing this research is to develop myself and to serve this thing as stepping stone to make a thesis and in consideration in making a book. Now I am making this just to show you how the proper process of learning is. The purpose of this research is to provide us significant ideas about real learning styles, study skills and thinking skills in analyzing some neither questions nor problems that we don’t know and to improve and enhance our memory in studying some lessons in a book. It also improves us to organize our studies, express our ideas clearly and effectively and how to communicate with others clearly and fluently. The first part of this research is focused on defining the three bodies of skills and you will know the utilization of effective language-learning strategy is. These three bodies of skills approaches us to have more experience on how to learn to be critical to success in school, considered essential for acquiring new good grades and useful for learning through out’s life. Of course this convinces us that these skills can be applied in other areas...
