What are the 3 building blocks in the economic way of thinking? • scarcity & choice • model building • pitfalls of economic reasoning
What is theeconomic problem? Providing for people’s wants and needs in a world of scarcity
What is meant by scarcity? The condition in which wants are forever greater than the available supply of time, goods, and resources
What does scarcity force us to do? It forces us to make choices
What are resources? The basic categories of inputs used to produce goods and services
What are the three categories of resources? Land Labor Capital
What is aland resource? A shorthand expression for any natural resource provided by nature
What is labor? The mental and physical capacity of workers to produce goods and services
What is capital? The physical plants, machinery, and equipment used to produce other goods
What isfinancial capital? The money used to purchase capital
What is entrepreneurship? The creative ability of individuals to seek profits by combining resources to produce innovative products.
Labor Land Capital Entrepreneurship organizes resources to produce goods and services
What is economics? The study of how society chooses to allocate its scarce resources to the production of goods and services in order to satisfy unlimited wants
What is macroeconomics? The branch of economics that studies decision-making for the economy as a whole
What is microeconomics? The branch of economics that studies decision-making by a single individual, household, firm, industry, or level of government
What is the purpose of an economic model? To forecast or predict the results of various changes in variables
What is thescientific method? • Problem identification • Model development • Testing a theory
Identify the problem Develop a model basedon simplified assumptions Collect data andtest the model
What are the two common pitfalls in understanding how the economy works? • failing to understand the ceteris paribus assumption • confusing association with causation
What assumption is always made when testing a model? ceteris paribus
What isceteris paribus? A Latin phrase that means that while certain variables can change, “all other things remain unchanged”
What is the difference between association and causation? We cannot always assume that when one event follows another, the first caused the second
Why do some economists disagree? The answer lies in understanding the difference between positive and normative economics
What ispositive economics? An analysis limited to statements that are verifiable
What isnormative economics? An analysis based on value judgement

Scarcity is the fundamental economic problem that human wants exceed the availability to time, goods, and resources. Individuals and society therefore can never have everything they desire.
Resources are factors of production classified as land, labor, and capital. Entrepreneurship is a special type of labor. An entrepreneur combines resources to produce innovative products.
Economics is the study of how individuals and society choose to allocate scarce resources in order to satisfy unlimited wants. Faced with unlimited wants and scarce resources, we must make choices among alternatives.
Society Chooses Resources Scarcity Unlimited wants
Macroeconomics applies an economy wide perspective that focuses on such issues as inflation, unemployment, and the growth rate of the economy.
Microeconomics examines individual decision-making units within an economy. Microeconomics studies such topics as a consumer’s response to changes in the price of coffee and the reasons for changes in the market price of personal computers.
Models are simplified descriptions of reality used to understand and predict economic events. An economic model can be stated verbally or in a table, graph, or equation. If the evidence is not consistent with the model, the model is rejected.
Collect data and test the model Develop a model based on assumptions Identify the problem
Ceteris paribus holds “all other factors unchanged” that might affect a particular relationship. If this assumption is violated, a model cannot be tested. Another reasoning pitfall is to think association means causation.
Positive economics uses testable statements. Often a positive argument is expressed as an “if-the” statement. Normative economics is based on value judgments or opinions and uses words such as good, bad, oughtto, and ought not to.
