Document Summary

Economics tells us how to make the best use of our scarce resources. Your opportunity cost is what is your next best option. I would have gone to georgia southern with all my friends from home. When you made the decision, you asked yourself what makes you the most happy. Made the decision that maximized our utility (utility = our happiness) Economics assumes people are rational and self-interested (not the same as selfish, but people make decisions to make themselves happy) Not only because it"s the right thing to do but it makes them happy. When the benefit falls below the marginal cost (i get full) My expected utility from the taco is less than the money it costs me to purchase it. Describe if the following statements are microeconomic or macroeconomic. Describe the trend of the national unemployment rate over the past 10 quarters.

Need help revising, and recommendation for a conclusion.

Throughout this paper is my understanding of what I have learned in class chapters 1-4, expressing my understanding and opinions. Economics is the study of how we deal with scarce resources. Microeconomics specially deals with business in the home country exclusively. This type of economics affects small businesses in the home country only. On the other hand, macroeconomics concerns our national welfare concerning trade and international business.

I believe that many things affect our economy on a microeconomics level. Things such as our understanding of our country in reflection to the world are very important. That is why we study ourselves before we study the macroeconomic principle of the world. Understanding ourselves is what microeconomics teaches us. Working from the inside out. The world is a place where there are differences in our wants and what we get. That is what makes items scarce. That is what positive economics is. Positive economics deals with what is and what we have. The other type of economics is called normative statements. This deals with what we should receive instead of what is and deserved to some extent. It's our scarce resources that determine our allocation of resources and how we use our resources and time. This is where opportunity costs come in, giving up something to do something. A successful business or country never ignores opportunity costs. We must ensure that we have a comparative advantage instead of the absolute advantage. Our resources must be used to achieve maximum output. Comparative is met when we have fewer opportunity costs to make some certain products than the other person or entity.

My initial understanding was scarcity was oil potentially running out, but we have so much of it that you can always find more with techniques such as fracking. Now it's obvious to me, one of our most scarce resources is time. You cannot avoid the 8,760 hours in a year. I understand that people have unlimited wants but limited resources. Everything has a cost and we must make a choice as we don't have unlimited farms, factories workers, etc. scarcity forces choices and this ties in with opportunity cost, for every gun made, a theft from the hungry is made. The opportunity cost not being used to feed the poor, but to make guns. And I find it easy to understand no one can have everything choices must be made on benefits. If I'm going to school, imp giving up making cash, as I'm giving up money for an education, I value education more. Scarcity is also related to the invisible hand. As it's an achievement that leads free markets and capitalism through competition for scarce resources.

My understanding of the invisible hand is a person neither intends to promote public interest and does not know how much he is promoting it. Only intending on his own gain. Without being his intention a person can be lead by the invisible hand to do good for society by pursuing one's own self-interest. Going into equity and efficiency the invisible hand does ensure both equity and efficiency. People work in their selfish ways to maximize profit while also contributing to the economy as a whole. It can also be argued that as the invisible hand wants to ensure efficiency, it cannot guarantee efficiency, because it can fail to produce an efficient allocation of resources, which in turn lead to a market failure. It can also be argued that it can't guarantee equity because not everyone gets a fair price. The way I like to remember efficiency is with a real-life example, like a reduction in the number of workers needed to produce a particular good for a particular amount. Equity refers to the ownership interest in an asset, for example, if a person owns a house with a market value of $800,000 and owes $100,000 on the mortgage leaving a $700,000 equity in the home.

It can be predicted that if the price of beef increases - ceteris paribus-the quantity of beef demanded by buys will decrease. In other words, if the price of beef increases, then the quantity of beef increases, then the quantity of beef demanded will decrease because all things have to be equal. In-class lecture thought me all other things remaining the same. Economists use ceteris paribus to determine the effect of a factor when all other factors have been held the same and helps simplify the study and get a more refined data set.

Economists deal with many issues that pertain to assuring that both a countries domestic output is efficient and that there is an effective trade balance. This means that there are a balance and limit on the amount of imports. Also, this means home production must be able to meet export demands. There are many factors that affect the production of goods and their effect on shifting the production possibilities frontier. This involves evaluating every detail including knowing the products and any close substitutes and compliments. It also involves knowing how an action or other external force will affect demand. This is called price elasticity; Substitutes are products that can replace any given product or service. An example of this would be Coke and Pepsi. The presence of substitutes affects price elasticity because if there are other options, then any change to the price or quality of the product will cause a shift of the demand curve. O course, price is a huge reason why the demand for a product decreases or increases yet it doesn't shift the curve because of the price only. This price change will cause a domino effect that will end with the shifting of the demand curve because it will cause an increase or decrease in demand of the substitute good if the price change is either lower or higher respectively. This price change serves as a catalyst that will change people's desire to spend more money on a more expensive product and that will instead choose to buy the substitute good for cheaper or buy more of the desired product. The change in the price of actual products will not shift the demand curve yet the change of the price of substitutes will because it serves to change people's purchasing behavior. On the other hand, compliments serve to boost demand when there is a decrease in price. The use of complementary goods is dependent upon another product. An example of this would be hot dogs and buns. If the price of hotdogs decreases then, conversely, the demand for hot dog buns will increase because of this change in price. In this scenario, the decrease in price will cause a positive shift in the demand curve because of people's desire and willingness to buy more buns. This is an example of a demand shifter. There are a few other demand shifters. The shifters of the demand curve are changes in expectations, disposable income, price of substitute goods and complements, tastes and preferences, and population size and composition. Changes in income affect the demand curve because if income is lower then people tend to save any extra income instead of wasting it. Disposable income is minimized and spending is lower. This also causes people to see a perceived value of things and distinguishing between what is necessary and what is a relative luxury. The lower the income, the higher the saving and avoidance to spend. An example of this would be if someone needs to buy some medication and it is relatively expensive, that doesn't mean that someone won't buy the medication just because it is expensive. It is necessary. Other factors that contribute to spending and demand are having a price ceiling and price floor. Having a price ceiling is a limit on the price of the product this is a government-imposed idea that is meant to protect consumers from unfair pricing and other conditions that may be malicious or obscure. This affects demand because if there is a price ceiling there is a limit on profit on a unit-to-unit basis. The other factor is the price floor. This price floor was created to encourage competition and affect consumers' willingness to pay because sometimes this new price may be higher than the original price. This causes a negative impact on a product that has a less than wanted perceived value. Many factors contribute to economic prosperity and certainly do help assure that information is analyzed and implemented into an economic and business plan.

Case Study #3

TO WAL-MART OR NOT TO WAL-MART?

Wal-Mart is a $250-billion-a-year retailer. Eighty two percent of U.S. households made a

Wal-Mart purchase in 2002. It is the largest company in the world with a global

workforce of 1.4 million. Where Wal-Mart competes the average grocery prices are 14%

lower. In the past it was General Motors, IBM and other companies that were considered

to be the leaders in industry and the ones to watch. Now it is Wal-Mart that is being

studied in universities around the world.

At Wal-Mart, cost is king. Costs are kept low and this translates into goods being sold

for less. The entire organization is focused on reducing costs and passing those savings

on to the consumer. This allows poor people to buy food and other necessities that they

otherwise might not be able to afford. In the U.S. it dominates sales in a number of

categories : 32% of disposable diapers, 30% of hair products, 26% of toothpaste, 20% of

pet food and 13% of textiles.

Wal-Mart simply has developed the most efficient methods for operating their business.

Their inventory management, through a network of scanners, computers, and at-the-ready

suppliers, makes it the leader in successful turnover of inventory. How can we blame

Wal-Mart for being the efficient cost conscious giant that it is?

The Wal-Mart phenomenon has occurred at the same time that high-paying skilled jobs

are being lost in the manufacturing sector. When these jobs are lost, the alternative often

means being employed at Wal-Mart at a much lower pay scale with reduced benefits

such as medical insurance. Its labor costs are twenty percent less than those at

unionized supermarkets, and sales clerks make less, on average, than the federal poverty

level ($8.50 an hour).

Barbara Ehrenreich* has described the problems faced by the under class, such

as waitresses and Wal-Mart employees. They barely survive on a day-to-day basis, living

from hand to mouth, with no reserves, no safety net, no medical insurance and almost no

prospect of improving their positions in life.

The loss of manufacturing jobs has affected the lifestyles of many people. What they see

is the reality of reduced opportunity with a permanent reduction in wages and standards

of living. They are trapped in a new marketplace, with diminishing expectations and few

alternatives to shopping at Wal-Mart. This is a change in our American culture--the

dreams have now been down-sized.

Is Wal-Mart the hero or the culprit? After all, low prices, competition, and growth have

all been mantras that Americans have been chanting all of our lives. We were

told that if you built a better mouse trap, everyone would come to you. Well, Wal-Mart

has built a better mouse trap. Is there any logic in our looking at Wal-Mart as a

contributor to the loss of some our middle class or is it just jealousy and sour grapes?

For one thing, its hard line on costs has forced many factories to move overseas.

Wal-Mart imported most of the items it sells. Environmental standards

are lower in these countries where these goods are manufactured than they are in the

U.S. This probably results in increased health issues and costs. In addition, shipment of

goods many thousands of miles to their ultimate destinations, involve utilizing the

worldâs limited oil resources. When you add up all this, the cost of the goods may be

greater than if they were produced in this country.

Another issue is that Wal-Mart is a non-union employer paying wages that are below the

poverty level, with minimal health insurance coverage. As many employees cannot

afford the co-payment required for doctors office visits, when a medical crisis occurs they

are forced to use the emergency room facilities of local hospitals. The result is that the

community bears the direct cost of their medical treatment and the indirect, as well as

ancillary costs such as diminished work capacity, child care, etc.

There are other economic ramifications to the Wal-Mart explosion. When Wal-Mart

arrives in a town, âmain streetâ erodes. Neighborhood stores that used to provide goods,

services and paid their workers well, are eliminated, uprooting families and ways of life

in the process. The Wal-Mart decision to saturate Oklahoma City, resulted in the closure

of 30 supermarkets.

If Americans shop with price being the only factor that determines where they

purchase their goods, doesnât this mean the permanent down-sizing of our standard of

living? How can the local retail establishment survive when they canât compete with a

Wal-Mart? Look at what has happened to the local supermarket, bookstore, hardware

and clothing store. The demise of these small business constitutes the loss of a middle

class of society in a community. We need to think: As consumers are we better off

paying a little more to enable the local merchants and their families to survive in order to

preserve the character of our communities and society or should we concern ourselves

with price only?

HERE IS YOUR DILEMMA:

You are the mayor of a small city in the West. You canât worry about the 4,700 workers

at IBM and the other workers at technology companies who lost their jobs. Your problem

is a more local one.

A Wal-Mart representative has approached you about the possibility of building a super-

store within your city limits. The store would serve communities within a twenty-five mile

radius. The land that they intend to build upon would require new zoning. Wal-Mart

would expect a certain amount of property tax and other relief. If your city does not

want a super-store, you are certain that one of the other towns close-by would be happy

to accommodate their needs.

What studies would you require before deciding which way to vote? What ramifications

do you foresee with this new super-store? What would you ask of Wal-Mart before

agreeing to their request? How much input would you seek from the residents of your

city
