Study Notes

Modern Economics

Modern economics focuses on individual, firm, and government choices regarding resource use.
The study of economics involves trade-offs driven by scarcity (limited resources.)
Five core economic concepts include trade-offs, incentives, exchange, information, and distribution.

Trade-offs

All choices require trade-offs, stemming from scarcity.
Scarcity involves limited resources, money, and time.

Incentives

Incentives motivate decision-making, such as rewards and costs reflected in prices.
Individual choices are influenced by returns anticipated from various activities.

Exchange

Exchange involves the trade of goods and services.
Voluntary exchange in markets dictates which goods to produce.
A market is any location where exchange occurs.

Information

Informed choices require information.
Information is similar to other goods/services, but unique in its properties.

Distribution

Markets determine which goods individuals receive based on demand and supply of resources (goods, labor and capital).
Markets also determine who receives the produced goods.

The Three Major Markets

The product market facilitates exchanges of final goods and services.
The labor market involves workers selling labor and firms hiring workers.
The capital market encompasses saving and fund-raising by individuals, companies, and governments.

The Two Branches of Economics

Microeconomics explores the decision-making processes of households and firms in specific industries, focusing on prices and production.
Macroeconomics focuses on the overall economy by studying aggregate variables' behavior.

The Science of Economics

Economics is a social science.
It involves assumptions (hypotheses) and derived conclusions.
Theories are logical reasoning that connect assumptions to conclusions.
The accuracy of conclusions is reliant on accurate assumptions.

Positive and Normative Economics

Positive economics describes the economy's functional aspects (facts), using "is" statements.
Normative economics evaluates the economy's value and suggests alternative paths (what should be), using "should be" statements.

Thinking Like an Economist (Chapter MI2)

The basic competitive model assumes rational consumers, profit-maximizing businesses, and competitive markets.
The role of government is disregarded for initial analysis and exploration of models.

Rational Individuals

Scarcity necessitates choices.
Rationality in economics assumes self-interest in decision-making.
Individuals rationally weigh costs and benefits.
Individuals with differing interests explain different decisions.
Economists don't judge preferences but rather accept them.

Competitive Markets

Competitive markets involve numerous firms offering identical products to multiple consumers.
Firms in competitive markets act as price takers.
Firms produce output matching demand.
Firms are small relative to the market size.
Firms charging higher prices lose all customers.
Market price consistency is essential for firms operating in the market.

The Basic Competitive Model as a Benchmark

The basic competitive model blends rational consumers with profit-maximizing firms in a competitive market to illustrate production and allocation.
It addresses fundamental questions about production quantity, production methods, recipient determination, and the decision-making process.
This model isn't a flawless representation of actual economies.

Efficiency in the Basic Competitive Model

The basic competitive model signifies Pareto efficiency, meaning no resource waste.
Efficiency implies maximizing output without sacrificing other goods.
Efficiency implies that maximizing one individual's wellbeing necessarily disadvantages someone else.

Opportunity Sets

Opportunity sets represent possible goods combinations, impacted by resource limitations (budget, time constraints).
All combinations are not attainable due to scarcity.
Budget or time constraints define opportunity sets.

Budget Constraint

Budget constraints involve limited spending ($120) on goods (pens, books) with specific prices ($10 per pen, $20 per book.)
Constraints limit achievable combinations.

Time Constraint

The constraint on daily time (24 hours) limits the achievable activities which may impact decisions.

The Production Possibilities Curve (PPC)

The PPC shows the trade-offs between goods possibilities given resources and technology.
PPC is curved due to different required input mixes.
It illustrates production possibilities for a firm or society.

The Production Possibilities Curve, cont.

Guns and butter illustrate opportunity costs (the next best option sacrificed).
The fixed trade-offs in the PPC scenario showcase these costs.

Optimal Production on the PPC

Points inside the PPC indicate underemployment of resources, thus lower production possibilities.
Optimal production output would fall on the curve.
Inefficient points are located inside the curve, implying resource underutilization.

Principle of Diminishing Returns

Increasing inputs progressively produces progressively smaller output increments, assuming other inputs are held constant.
Adding consistent units of inputs to fixed inputs leads to a decreasing rate of additional output growth.

Opportunity Costs

Opportunity cost refers to the value of the next best alternative option sacrificed by choosing a particular action.
Resource use is constrained by the resources' value.
Opportunity cost is depicted by the PPC and time/budget limitations.

Opportunity Costs, cont.

Education opportunity costs comprise tuition, room and board, books, travel, and foregone earnings.

Sunk Costs

Rational decision-makers disregard sunk costs (past unrecoverable investments).
Previous investments don't influence future decisions.

Marginal Costs

Marginal cost is the incremental cost of producing or consuming one additional unit.

Basic Steps of Rational Choice

Identify opportunity sets.
Categorize trade-offs.
Calculate costs accounting for opportunity costs and marginal costs (ignoring sunk costs.)
