When most of us think of economics, we think of money. But the world of economics is far more complex than just cash. Every culture has an economy and it is this economy that influences many decisions and elements of each culture. Currency, natural resources, trade, scarcity, credit, and supply/demand are all around us each day and play a central role in our culture. To varying extents, the economy of a given culture is one of its primary concerns and helps dictate elements of life for all members of a society. Unfortunately for us, the world of economics is highly complex and very abstract making it really difficult to understand. However, we can cover and learn the basics because having general knowledge and vocabulary will help us to better understand cultures from all around the world.

Glossary of Terms

Supply and Demand

Supply (S): the amount of a good or service which producers are willing and able to produce at a given price.

Demand (D): the amount of a good or service which consumers are willing or able to buy at a given price.

Producers: Those who are on the selling side and create the supply of a given product.

Consumers: Those who are on the buying side and directly influence the demand of a given product.

  1. Producers are willing to produce more of a good or service when prices are high.

  2. Consumers are willing to buy more of a good or service when prices are low.

  3. Equilibrium Price (E): is the point at which both consumers and producers have found a middle ground. It is the price at which the amount produced and the amount demanded are the same.

  4. When the price goes above the equilibrium price then consumers will demand less than producers supply. Producers will then have to lower their prices to appeal to the consumers or else they will end up with surplus. To unload surplus they need to lower prices so that consumers will be more apt to buying.

Market Clearing Price (MCP): the highest price that a seller can charge and still sell all of his or her products. This clears the seller out of the supply. It also clears out the demand because the MCP is low enough for the buyers to buy as much of the product as they want. Under the MCP the supply perfectly satisfies the demand. This is the point at which the equilibrium is established.

    1. a. A rise in demand causes the price and the supply to rise.
    2. b. The rise in supply causes the demand to fall.
    3. c. The fall in price causes demand to rise.
  2. Market: the market for a product is the combination of all the demanders and all of the suppliers of a product.

  3. Supply and Demand Cycle:

To make money in this cycle one must increase supply as demand starts to rise, and cut price as demand starts to fall. If one can increase supply to meet the rising demand, one can satisfy the demand and make money.

  1. Customer Preference: this is the most basic source of demand. If one wants a specific product or service then someone will sell it. The smartest sellers look for changes in customer preference, and gets a supply of what the customer wants. When supply exceeds the total preference of the customer, then price drops. When supply is below customer preference, than the price increases. Price increases and decreases relative to the scarcity of the good or service, and the preference or demand of the customer.

Other Terms

Competition: In general, the actions of two or more rivals in pursuit of the same objective is considered competition. In the context of markets, the specific objective is either selling goods to buyers or alternatively buying goods from sellers. When several companies compete with one another to get the attention of consumers, it both lowers price and increases quality. When companies compete they strive to outdo one another thus inspiring more inventiveness and ingenuity and lower price since consumers are always looking for the lowest price possible. Competition generally benefits consumers but it also leads to better products which benefits everyone.

When one producer completely dominates an industry or product thus eliminating competition. If this producer possesses the means for production of the product and has no direct competition, it allows this producer to increase prices as much as it wants because no one competes for price. Monopolies can really only exist when the product is one that is needed by consumers. Gasoline, phone service, and electricity are all examples of products/industries that are susceptible to monopoly.

The promise of future payment in exchange for money, goods, services, or anything else of value. Car loans, mortgages, credit cards, and government securities are all forms of credit. In fact, credit is an extremely wide-spread and critical part of our economy. About one-third of the stuff consumers buy, and nine-tenths of business expenditures are completed with credit. Most business capital, and consumer car and home purchases would be impossible without credit.

Interest: It is important to note that with credit the lender generally charges interest as payment for loaning a consumer the money. For example, if I have been using my Visa card often I could accumulate a balance on that card for $1,000. If I donÕt have $1,000 to pay Visa to eliminate the balance, Visa will charge me interest. If Visa charges 10% interest per month, then if I have a balance of $1,000, I will have to pay Visa $100 per month as a fee for lending me the money. Credit works well for consumers because it allows them to purchase more expensive items without paying for them all at once. Purchases of homes, boats, and other very expensive items are sold more often as a result. At the same time, creditors (the lenders, i.e. Visa) also make a profit.
