Who is a Consumer
An individual who buy products or services for personal use
and not for manufacture or resale. A consumer is someone who can make the decision
whether or not to purchase an item at the store, and someone who can be
influenced by marketing and advertisements. Any time someone goes to a store
and purchases a toy, shirt, beverage, or anything else, they are making that
decision as a consumer.
Types of Economic
Goods
Consumer good, in
economics, any tangible commodity
produced and subsequently purchased to satisfy the current wants and perceived needs of the buyer. Consumer goods are
divided into three categories: durable goods, nondurable goods, and services.
Consumer durable goods have a
significant life span, often three years or more (although some authorities
classify goods with life spans of as little as one year as durable). As with
capital goods (tangible items such as buildings, machinery, and equipment
produced and used in the production of other goods and services), the
consumption of a durable good is spread over its life span, which tends
to create demand for a series of maintenance services. The similarities in the
consumption and maintenance patterns of durable and capital goods sometimes
obscure the dividing line between the two. The longevity and the often higher
cost of durable goods usually cause consumers to postpone expenditures on them,
which makes durables the most volatile (or cost-dependent) component of
consumption. Common examples of consumer durable goods are automobiles,
furniture, household appliances, and mobile homes. (See also capital.)
Consumer nondurable
goods are purchased for immediate or almost immediate consumption and
have a life span ranging from minutes to three years. Common examples of these
are food, beverages, clothing, shoes, and gasoline.
Consumer services are intangible products or actions that are typically
produced and consumed simultaneously. Common examples of consumer services are
haircuts, auto repairs, and landscaping.
Supply and Demand
Supply and demand is perhaps one of the most
fundamental concepts of economics and it is the backbone of a market economy. Demand
refers to how much (quantity) of a product or service is desired by buyers. The
quantity demanded is the amount of a product people are willing to buy at a
certain price; the relationship between price and quantity demanded is known as
the demand relationship. Supply represents how much the market can offer. The
quantity supplied refers to the amount of a certain good producers are willing
to supply when receiving a certain price. The correlation between price and how
much of a good or service is supplied to the market is known as the supply
relationship. Price, therefore, is a reflection of supply and demand.
The relationship between demand and supply underlie the forces behind the
allocation of resources. In market economy theories, demand and supply theory
will allocate resources in the most efficient way possible. How? Let us take a
closer look at the law of demand and the law of supply.
A. The Law of Demand
The law of demand states that, if all other factors remain equal, the higher
the price of a good, the less people will demand that good. In other words, the
higher the price, the lower the quantity demanded. The amount of a good that
buyers purchase at a higher price is less because as the price of a good goes
up, so does the opportunity cost of buying that good. As a result, people will
naturally avoid buying a product that will force them to forgo the consumption
of something else they value more. The chart below shows that the curve is a
downward slope.
A, B and C are points on the demand curve. Each point on the curve reflects a
direct correlation between quantity demanded (Q) and price (P). So, at point A,
the quantity demanded will be Q1 and the price will be P1, and so on. The
demand relationship curve illustrates the negative relationship between price
and quantity demanded. The higher the price of a good the lower the quantity
demanded (A), and the lower the price, the more the good will be in demand (C).
B. The Law of Supply
Like the law of demand, the law of supply demonstrates the quantities that will
be sold at a certain price. But unlike the law of demand, the supply
relationship shows an upward slope. This means that the higher the price, the
higher the quantity supplied. Producers supply more at a higher price because
selling a higher quantity at a higher price increases revenue.
A, B and C are points on the supply curve. Each point on the curve reflects a
direct correlation between quantity supplied (Q) and price (P). At point B, the
quantity supplied will be Q2 and the price will be P2, and so on. (To learn how

Time and Supply
Unlike the demand relationship, however, the supply relationship is a factor of
time. Time is important to supply because suppliers must, but cannot always,
react quickly to a change in demand or price. So it is important to try and
determine whether a price change that is caused by demand will be temporary or
permanent.
Let's say there's a sudden increase in the demand and price for umbrellas in an
unexpected rainy season; suppliers may simply accommodate demand by using their
production equipment more intensively. If, however, there is a climate change,
and the population will need umbrellas year-round, the change in demand and
price will be expected to be long term; suppliers will have to change their
equipment and production facilities in order to meet the long-term levels of
demand.
C. Supply and Demand Relationship
Now that we know the laws of supply and demand, let's turn to an example to
show how supply and demand affect price.
Imagine that a special edition CD of your favorite band is released for $20.
Because the record company's previous analysis showed that consumers will not
demand CDs at a price higher than $20, only ten CDs were released because the
opportunity cost is too high for suppliers to produce more. If, however, the
ten CDs are demanded by 20 people, the price will subsequently rise because,
according to the demand relationship, as demand increases, so does the price.
Consequently, the rise in price should prompt more CDs to be supplied as the supply
relationship shows that the higher the price, the higher the quantity supplied.
If, however, there are 30 CDs produced and demand is still at 20, the price
will not be pushed up because the supply more than accommodates demand. In fact
after the 20 consumers have been satisfied with their CD purchases, the price
of the leftover CDs may drop as CD producers attempt to sell the remaining ten
CDs. The lower price will then make the CD more available to people who had
previously decided that the opportunity cost of buying the CD at $20 was too
high.
D. Equilibrium
When supply and demand are equal (i.e. when the supply function and demand
function intersect) the economy is said to be at equilibrium. At
this point, the allocation of goods is at its most efficient because the amount
of goods being supplied is exactly the same as the amount of goods being
demanded. Thus, everyone (individuals, firms, or countries) is satisfied with
the current economic condition. At the given price, suppliers are selling all
the goods that they have produced and consumers are getting all the goods that
they are demanding.
As you can see on the chart, equilibrium occurs at the intersection of the
demand and supply curve, which indicates no allocative inefficiency. At this
point, the price of the goods will be P* and the quantity will be Q*. These
figures are referred to as equilibrium price and quantity.
In the real market place equilibrium can only ever be reached in theory, so the
prices of goods and services are constantly changing in relation to
fluctuations in demand and supply.
E. Disequilibrium
Disequilibrium occurs whenever the price or quantity is not equal to P* or Q*.
1. Excess Supply
If the price is set too high, excess supply will be created within the economy
and there will be allocative inefficiency.
At price P1 the quantity of goods that the producers wish to supply is
indicated by Q2. At P1, however, the quantity that the consumers want to
consume is at Q1, a quantity much less than Q2. Because Q2 is greater than Q1,
too much is being produced and too little is being consumed. The suppliers are
trying to produce more goods, which they hope to sell to increase profits, but
those consuming the goods will find the product less attractive and purchase
less because the price is too high.
2. Excess Demand
Excess demand is created when price is set below the equilibrium price. Because
the price is so low, too many consumers want the good while producers are not
making enough of it.
In this situation, at price P1, the quantity of goods demanded by consumers at
this price is Q2. Conversely, the quantity of goods that producers are willing
to produce at this price is Q1. Thus, there are too few goods being produced to
satisfy the wants (demand) of the consumers. However, as consumers have to
compete with one other to buy the good at this price, the demand will push the
price up, making suppliers want to supply more and bringing the price closer to
its equilibrium.
