Quantity demanded

Of a good or service is the amount that consumers plan to buy at a particular price.

Opportunity cost

Opportunity cost of something is that must be given up to get it.

Rise in the price (quantity demanded)

Other things remaining the same, brings a decrease in the quantity demanded and a movement up along the demand curve.

Fall in the price (quantity demanded)

Other things remaining the same, brings an increase in the quantity demanded and a movement down along the demand curve.

The Law of Supply

Other things remaining the same, the higher the price of a good, the greater is the quantity supplied. The lower the price of a good, the smaller is the quantity supplied.

Scarcity

Our inability to satisfy all our wants

Entrepreneurship (factor of production)

Profit -The human resource that organizes land, labor, and capital.

Demand Function

Qd = a (b*p) Dependent variable = Qd Independent variable = P

Supply function

The benefit from pursing an additional increase in an activity, is its marginal benefit. MB is usually downward sloping.

Marginal cost (MC)

The cost from pursing an additional increase in an activity is its marginal cost. MC is usually upward sloping.

Demand decreases

The demand curve shifts leftward.

Demand increases

The demand curve shifts rightward.

Fall in price (quantity supplied)

The good brings a decrease in the "quantity supplied" and causes the movement down along the supply curve.

Rise in price (quantity supplied)

The good brings an increase in the "quantity supplied" and causes the movement up along the supply curve.

The Law of Demand

The higher the price of a good, the smaller is the quantity demanded.

Microeconomics

The study of choice that households & firms make, the way those choices interact in the market, and the influence of the government

Macroeconomics

The study of the performance of national and global economies, such inflation, unemployment, oil price, exchange rate, interest rate,...

Supply decreases

The supply curve shifts leftward

Supply increases

The supply curve shifts rightward

Complement in production

Two goods must produce together. -Positive relationship

Substitute in production

Two goods using same resources. -Negative relationship

Labor (factor of production)

Wages

Inferior good

When income increases, demand on the normal good decreases.

Normal good

When income increases, demand on the normal good increases.

Expected future price

When the expected future price of the good increases... negative related

Prices of factors of production

When the factors of production increases... decrease or negative related

Income Effect

When the price of a good or service rises relative to income, people cannot afford all the things they previously bought, so the quantity demanded of good or service decreases.

Substitute Effect

When the relative price of a good or service rises, people seek for substitutes for it, so the quantity demanded of the good and services decreases.

If MB>MC

Your choice is to do more of that activity.
