The document provides an overview of key concepts in applied economics for a class including rules, grading system, learning objectives, and definitions of terms like scarcity, needs vs wants, trade-offs, opportunity costs, supply, demand, and the branches of economics. Scarcity exists because resources are limited while wants are unlimited, and economics studies how people deal with scarcity. Trade-offs are options given up when making a choice, and the most desirable alternative given up is the opportunity cost. Supply refers to the total goods available for sale, while demand is the total needs and wants of customers. Applied economics applies economic principles to real-world problems at the micro or macro level.

and applied science in terms of nature
and scope

Economics
5. Scarcity
Scarcity is the condition in which
our needs and wants are greater
than our limited resources.
6. Why is SCARCITY linked to
Economics?
Scarcity is the reason why people have to study and
practice economics.
Economics studies how people distribute or divide their
limited resources in order to satisfy their unlimited
wants. Or simply, it is the study of how individuals and
societies deal with scarcity.
7. NEED vs. WANT
Needs are the things we can’t live
without.
Wants are the things we can live
without.
8. Trade-offs
When making choices, there are things
that we need to give up.
Trade-offs consist of all the options that
we give up when we make a choice.
9. Opportunity Costs
Among all your trade-offs, the most desirable
alternative that you gave up is called the opportunity
cost.
The key to making the best possible decision is to
minimize your opportunity cost by selecting the
option that gives you the largest benefit.
10. The Branches of Economics
Microeconomics is a branch of economics that is
concerned with the decision-making done by smaller
economic units such as individuals or consumers, firms
and industries.
Macroeconomics on the other hand is the study of the
large economy as a whole or the aggregate economy.
11. SUPPLY
Supply refers to the total number of goods or services available for
sale. These goods or services are produced by making use of the
factors of production consisting of land, labor and capital.
- Land refers to all natural resources or any raw materials coming
from the ground that is used to produce supply.
- Labor is the work done by people or human resources.
- Capital does not only mean money as this can be in the form of
man-made tools or objects that may be used to produce supplies.
12. DEMAND
Demand refers to the aggregate or the
totality of the needs and wants of the
customers.
NOTE: Balancing supply & demand is one of the
goal of Economics so that scarcity is eliminated.
13. Applied Economics
It is the application of the principles of supply,
demand, trade-offs, opportunity-costs, and
other economic theories to solve real-world
problems. It may be practiced in the
microeconomic or macroeconomic level.

Editor's Notes
Quick background of what applied economics is: scarcity, trade offs, opportunity costs, factors of production, law of supply and demand, market structures, how to achieve balance or equilibrium in the economy, unemployment, underemployment, competition, etc.
Cite instances of scarcity.
Since we are unable to have everything we desire, we must make choices on how we will use our limited resources.
Who can differentiate. Give examples?
you planned to spend your limited allowance to buy 2 pieces of siopao and softdrinks to satisfy your hunger. Your other option is to pay for a heavy value meal at 120 pesos or buy your favorite meal combo at 115 pesos. You gave these options up since you can only afford to pay for the siopao and drinks. The choices that you’ve given up are your trade-offs.
No matter what choice you make, there is an opportunity cost, or next- best alternative, that must be sacrificed. Opportunity cost is the highest- valued alternative that must be sacrificed in order to get something else.
