The Nature and Method of Economics Chapter One
Economics • Social science concerned with the efficient use of scarce resources to achieve maximum satisfaction of economic wants.
Economic Perspective • Economists view things through a unique perspective: • This way of thinking has several critical and closely interrelated features. • Scarcity & choice • Rational behavior • Marginalism: benefits and costs
Scarcity and Choice • Since human and property resources are scarce (limited), the goods and services we produce must also be limited. • Scarcity limits our options. As a result, we must make choices.
Rational behavior • Individuals will make different choices under different circumstances which will increase their utility (satisfaction). • Rational decisions may change as costs and benefits change.
Marginal Analysis: Benefits & Costs • “marginal” – means extra, additional, or a change in. • Each decision made involves marginal benefits and costs. • As long as the marginal (additional) benefits exceeds the cost, you should pursue that choice.
