It's the first chapter in the text for a course that most of your students wish they did not have to take. My class opens with an admission that I am very aware of this fact, and have a big job responsibility – to explain why it was worthwhile to spend my life working with economics and that it will pay them to learn why.

Chapter 1 is about how economists think, and why they think that way. In my opinion the most important concepts to convey are:

1 Why economists use models instead of collecting facts in an ad hoc manner. The emergency room algorithm seems to work fairly well, possibly because it immediately turns a popular fable (the importance of personalized medical relationships) on its head. The doctor is more likely to make a correct diagnosis when time and information are scarce by treating you as a random sample from the population, asking you questions known to reliably distinguish heart attacks from other conditions, and asking no other questions. That's the same reason you start with supply and demand when faced with a problem in a market you have not encountered before.

2 The most basic ideas of rationality and choice under constraints, plus a refresher on opportunity cost, marginal reasoning, and competition in general.

3 The importance of limited and costly information in models and life. Most students believe that knowledge is power, but only because they have heard it mindlessly repeated by so many authorities. I like the example of the expensive industry newssheet whose value stems in large part from its ability to destroy information that the reader is likely to find irrelevant or false.

4 You should bring up examples of phenomena that economists have problems explaining with a rational choice model like the R-rated movie paradox. It makes you more human to the students and is…...

...Marginal Analysis 1 | Consumer Products, Inc. | Memo To: CPI Board Member From: Kristi Richardson, CEO Date: 9/2/2012 Re: Marginal Analysis of Impending Expansion MARGINAL ANALYSIS Marginal Analysis is a method used in microeconomics in which small variations in specific variables are considered in relation to the effect on related variables and the system as a whole (WebFinance, 2012). Understandably after the last presentation many board members were curious as to how the company’s impending expansion would impact the company’s profitability specifically in the toothpaste division. As we are all aware the market is impeccably competitive and the current price as it stands is $42.00 per case of toothpaste. CPI has marginal cost of MC=.006Q, we now must specify the amount the company needs to produce. To capitalize on our profits the marginal cost must be equivalent to the marginal profits. We know that we have $42.00 = .006Q. The Q (quantity) is 7000 (42/.006). So currently CPI produces 7000 cases of toothpaste to maximize revenues. If we choose to raise prices exclusively in the toothpaste market, CPI could potentially lose consumer demand to other market competitors. The current conditions are considered to be perfect because no one company or consumers for that matter can influences prices the market does that. In perfect competition there are several producers and consumers, there is similarity of goods, there is perfect information and there......

According to Flamand, 1999-2011, “an ethical dilemma is situations were in moral precepts or ethical obligations conflict in such a way as to make any possible resolution to the dilemma morally intolerable”(para.1). “In other words, an ethical dilemma is any situation in which guiding moral principles cannot determine which of course an action that is right or wrong”( Flamand, 1999-2011, para.1). Dilemmas in the work force are quite common and require some sort of ethical explanation. Both employees and employers have to face dilemmas in any type of undersized or large organization. Some conflicts are bond to rise at even given moment because of gender, age, education, race, religion, and employment statues. The most common dilemmas I have experienced at work include honesty, power, loyalty, authority, and confidentiality. The Experience/Analyze Sometimes making a right decision can be difficult because as I think about my personal values and what they mean to me.

...4. Within the limitations of the data that have been provided, it’s safe to say that the president was probably correct in being concerned about the profitability of the products. However, the problem appears to be with the specialty product line rather than the standard product line. Conventional overhead cost assignment using a volume based measure has resulted in the high volume product subsidizing the low volume product. Consequently, unit costs for both products are misleading. These misrepresentative costs have had a major impact on different areas of the business. These include but are not limited to management’s pricing policies and their perception of the margin being attained on each product. The specialty briefcases are seemingly being sold at a loss even without considering the available manufacturing costs. The excerpted table below showcases the exact values. Gross Margin of CarryAll Products Description | Selling Price Per Unit | Unit Product Cost | Gross margin and/or loss per unit | Standard Briefcases | $36 | $29.98 | $6.02 | Specialty Briefcases | $40 | $45.09 | ($5.09) | Based on the table above, the company should not shift its resources entirely to the production of the specialty briefcases. Whether or not the specialty briefcases can be made profitable depends on a number of factors. One of those factors being the sensitivity of the market to an increase in the selling price of the specialty line of briefcases. 5. Sally Henrie stated......

...Homework Assignment #3 1. What is the effect of universal health care, where the patients pay a price of zero at the point of service and the doctors get paid by a third party (either the government or the insurance companies). Make sure you address the impact of such a policy on (a) availability of services, (b) the poor patients, and (c) quality of services. Explain all your answers. In doing so, use a Demand/Supply diagram to help with your explanations… at least for (a). When patients pay a price of zero at the point of service, that means the supply quantity goes down when the demand quantity goes up (P=0 => QD>QS, so we will have a shortage, which means more patients when the quality of service will decrease, the quality of service will be bad, the availability of service will decrease, less and less supply. Poor patients probably will benefit from this effect of universal health care on a short period of time, but on a long term when the quantity of the demand will exceed the quantity supplied, resulting in a shortage, means the universal health care is not going to meet the demand of the patients, the availability of service and the quality of service will also decrease. 2. (a) Read Ch. 4 and 5 (Public Works Mean Taxes and Taxes Discourage Production – I am being coerced to put the titles here!!) (b) Find an article praising some public work and summarize what it says. (c) Criticize it by what you learn from the reading. (d) If we......

... Name Professor Subject Date Global Managerial Economics The small and medium-sized enterprises (SMEs) form a crucial part of the U.S. economy. The SMEs create the most jobs in the country; they target the ordinary Americans for employment thus making them a very important component of the economy. Without the SMEs, the economy will bleed millions of jobs, adversely affecting the economy. This is the reasoning behind the drive by President Obama to give this sector newly acquired impetus and promote it to create more jobs for Americans and grow the economy. The target of the National Export Initiative (NEI) is to boost the export capacity of the SMEs in the U.S. by supporting them; the administration reasons that this will result in the creation of two million jobs. The intention is good, but the challenge lie in the operationalization of the policy and ensuring it works in the actual market (Audretsch, 100). The international market and the export market is often dominated by the big corporations with many resources to invest; this makes them strong and gives them the ability to compete with the big corporations that are players in the international market. The SMEs form the U.S. lack, the resources, know how, and the experience to compete with the established world trade players form the Europe Union, China, and India. This is where the Export Promotion Cabinet steps in to help the U.S. SMEs succeed in the competitive export market (Audretsch, 101). The cabinet should take...

...1.0 Why is operations management important for organisation you have selected? Operations Management explores the way organizations produce and distribute goods and services. Everything you wear, eat, sit on, use or read comes to you courtesy of the operations managers who organized its production and distribution. Goods such as automobiles, airplanes, computers and houses, must be produced, as do the services provided by hospitals, ski resorts, trucks, and airlines. It's the job of an operations manager to make sure these activities occur when and how they are planned. Operations Management is the systematic development and control of the processes that transform inputs into goods and services. The operations function comprises a significant percentage of the employees and physical assets in most organizations. Operations Managers are concerned with each step in providing a product or service. They determine what should go into an operating system, such as equipment, labour, facilities, materials, energy, and information, to produce the output. Operations Managers are also responsible for critical activities such as materials management, capacity planning, purchasing, scheduling and quality. The importance of Operations Management has increased dramatically in recent years. Significant competition, shorter product and service life cycles, better educated and quality-conscious consumers, and the capabilities of new technology have placed pressures on the operations......

...Zanab Al-Hilali Type Lab Proposal Assignment # 2 I am writing in regards to a solution to an issue in my Learn to Type lab. The problem is that my books and software are outdated. I highly suggest that you order new books and new updated software to be used for my Learn to Type lab. Please look over my proposal this week so that we may get new software and get the books ordered for the new term starting next week. Having new books and software will advance my students typing skills and increase their grades. The issue with the current software & books In the beginning of the new term, I will be teaching five Learn to Type labs each day. There are 20-28 students in each of my classes. The books that we have are outdated and they are the same ones that we have been using for the past 15 years. The information in the textbooks is no longer relevant. In fact, these are the same old typing books we used when we had typewriters to teach keyboarding. We are lacking the updated new software to help teach the students typing skills. The typing program we have does not work most of the time. The program does not fallow the book because it is newer than the book. Another difficulty with these books is that the information is very basic and does not create a challenge. The books do not comprise information about word processing or computer applications because they are so old. The only thing in the books is simple typing for typewriters. We only use......

...Q. How is GDP measured and what are its limitations as a measure of the quality of life? A. Gross Domestic Product (GDP) can be defined as the annual value of output produced by factors of production within a nation’s border. In other words, it is the sum of all incomes earned by the country’s residents when producing goods and services with resources located inside that country. GDP is not to be confused with Gross National Product (GNP), which measures the flow of output produced with resources, which are owned by the nation wherever they might be located. The difference between GDP and GNP is net property income from abroad. The word “gross” in both of these measures of national income, indicates that no account has been taken of depreciation. There are 3 methods of calculating GDP: the product/output method, the income method and the expenditure method. In theory, because they all claim to measure the same aggregate, they should all give the same total. This is shown below in the circular flow of income: However, in practice, this is unlikely to be the case. This is because extremely large sums arising out of millions of transactions paid over different time periods are being dealt with and it would therefore be very unlikely if all 3 measures coincided. The first way of measuring GDP is to add up annually all the value of the goods and services produced in the country, industry by industry. This is known as the output or......
