Equips us to answer questions Explain irregularity in our everyday lives Provide the background for other economic
disciplines Knowledge of basic economic theory Application of basic economic theory Gain insight in social and economic events
WHY?
Help us predict what is likely to happen
WHAT IS MICROECONOMICS?

THEMES OF MICROECONOMICS
![Page 17: MICROECONOMICS ECS201](https://reader036.vdocument.in/reader036/viewer/2022081420/568168e1550346895ddfdbe3/html5/thumbnails/17.jpg)
Optimal Trade-Off
Consumers- Limited income
- Trade-off for maximized well-being
Workers- When to enter
workforce- Work or
education?
Firms- What to produce?
- Resource available
THEMES OF MICROECONOMICS- TRADE-OFFS
Theory of the firm
Consumer Theory

•Trade-offs•e.g. Labour: Work for pleasure•Centrally planned economy = Prices set by government•Market economy = Prices determined by consumers, workers, firms
Prices
•Interactions to determine price

LIMITED RESOURCESTHEORIES AND MODELS
Theories = Explanations & Predictions
Model = Mathematical representation
![Page 20: MICROECONOMICS ECS201](https://reader036.vdocument.in/reader036/viewer/2022081420/568168e1550346895ddfdbe3/html5/thumbnails/20.jpg)
LIMITED RESOURCESPOSITIVE AND NORMATIVE
ANALYSIS
Positive- Central to microeconomics
- Explanations and predictions
- Describe relationships of cause and effect
Normative- Go beyond explanations
and predictions- “What is best?”
- Examine questions of what ought to be

MARKET
Definition: Collection of buyers and sellers Through actual or potential interactions Determine price of a product Or, set of products
Market = More than an industry Industry: Collection of firms that sell
same/closely related products. Potential interactions & actual interactions Arbitrage:
Significant difference in price of commodity Practice of buying low @ one location & sell
high at another location

MARKET
Competitive marketPerfectly competitive: Many buyers and
sellers e.g. agricultural markets Noncompetitive market
Many producersCartel: Group of producers act collectively
Market price:Competitive market = Single price = market
priceNot perfectly competitive = Different prices
Average price = Market price

MARKET
Market Definition:Buyers and sellers
Extent of the market:Determine which buyers and sellersBoundaries of a marketGeographical and i.t.o. range of products
Market definition importance:1. Understand who is actual and potential
competitors2. Public policy decisions

REAL VS NOMINAL PRICES
Nominal prices:Absolute price“Current-dollar”
Real prices:Price relative to aggregate measure of
prices“Constant-dollar”
Consumer Price Index Producer Price Index

IMPOTANT CONCEPTS CETERIS PARIBUS
Assumption used when designing models.Meaning: All variables other than the one
economist use will remain unchanged.Latin expression: “All other things being
equal” EQUILIBRIUM
Important in economic theoryA situation, once it has been reached, tends
to persistAll factors in balance.
