Economics, Business Law, and Career/Workplace Readiness
Economics
Economics studies scarcity and choice. Opportunity cost is the value of the next-best alternative. Demand and supply determine equilibrium price and quantity; a change in price moves along a curve, while changes in income, tastes, expectations, or related-good prices shift the curve. Elasticity measures responsiveness. Market structures range from perfect competition to monopoly. Macro indicators include GDP, inflation, and unemployment; fiscal policy uses government spending and taxation, while monetary policy uses money supply and interest rates.
Law and careers
Contracts require offer, acceptance, consideration, capacity, and legality. Torts are civil wrongs independent of contract. Agency, employment law, intellectual property, and consumer protection frequently appear. Career readiness includes resumes, interviews, professionalism, teamwork, ethics, and digital citizenship. Traps: confusing a shift in demand with a movement along it; mixing fiscal and monetary policy; treating every breach as a tort; and misclassifying employees as independent contractors.
Worked example
Nominal GDP is $220 billion and the price deflator is 110. Real GDP = nominal GDP ÷ (deflator ÷ 100) = 220 ÷ 1.10 = $200 billion. Rule of thumb: real values remove price-level changes; nominal values do not. If nominal GDP rises 10% while prices rise 10%, real output is unchanged.
