Question 1 Economics

What is absolute advantage?

Changes in income, tastes, prices of related goods (substitutes/complements), expectations, or number of buyers shift the demand curve; price changes cause movement along the curve. Nominal GDP uses current prices; real GDP adjusts for inflation using base-year prices to measure actual output changes. Comparative advantage is the ability to produce a good at a lower opportunity cost than others, basis for beneficial trade. Absolute advantage occurs when a country produces more of a good using the same resources than another.

Question 2 Economics

What is comparative advantage?

Comparative advantage is the ability to produce a good at a lower opportunity cost than others, basis for beneficial trade. Contractionary fiscal policy decreases spending or raises taxes to cool an overheating economy and curb inflation. Opportunity cost is the value of the next best alternative forgone when making a choice. It highlights the trade-offs inherent in decision-making. Aggregate supply shows total output firms produce at different price levels; short-run AS slopes up, long-run is vertical.

Question 3 Economics

Describe the supply curve.

Absolute advantage is producing more with same resources; comparative focuses on lower opportunity cost. Price elasticity of demand measures responsiveness of quantity demanded to a price change: (%ΔQd / %ΔP). Elastic if >1, inelastic if <1, unit if =1. The supply curve shows the quantity of a good producers are willing to sell at different prices, typically upward-sloping due to higher incentives at higher prices. Consumer surplus is the difference between what consumers are willing to pay and what they actually pay, represented by the area above the equilibrium price and below the demand curve.

Question 4 Economics

Define unemployment rate.

Cross-price elasticity measures how quantity demanded of one good responds to price changes in another: positive for substitutes, negative for complements. Market equilibrium occurs where supply equals demand, determining the equilibrium price and quantity with no shortage or surplus. The unemployment rate is the percentage of the labor force without jobs but actively seeking work. Business cycles are fluctuations in economic activity: expansion, peak, contraction (recession), trough.

Question 5 Economics

What are the three methods to calculate GDP?

Aggregate demand is total spending on goods/services at different price levels: AD = C + I + G + NX. GDP can be calculated via expenditure (C+I+G+NX), income (wages+profits+rents+interest), or production (value added at each stage). Economics is the study of how individuals, businesses, governments, and societies allocate scarce resources to satisfy unlimited wants. It examines production, distribution, and consumption of goods and services. Utility measures satisfaction from consuming goods; consumers maximize it subject to budget constraints.

Question 6 Economics

Distinguish between microeconomics and macroeconomics.

The tragedy of the commons occurs when individuals overuse shared resources (e.g., fisheries) due to no private incentives to conserve. Microeconomics studies individual markets, households, and firms, while macroeconomics examines the economy as a whole, including growth, inflation, and unemployment. Aggregate supply shows total output firms produce at different price levels; short-run AS slopes up, long-run is vertical. The law of supply states that, ceteris paribus, as the price of a good rises, the quantity supplied increases.

Question 7 Economics

What is the difference between positive and normative economics?

The tragedy of the commons occurs when individuals overuse shared resources (e.g., fisheries) due to no private incentives to conserve. Positive economics describes 'what is' using facts and testable statements, while normative economics involves 'what ought to be' based on opinions and value judgments. Utility measures satisfaction from consuming goods; consumers maximize it subject to budget constraints. Income elasticity of demand measures how quantity demanded responds to income changes: positive for normal goods, negative for inferior goods.

Question 8 Economics

What is Gross Domestic Product (GDP)?

Changes in income, tastes, prices of related goods (substitutes/complements), expectations, or number of buyers shift the demand curve; price changes cause movement along the curve. Perfect competition features many buyers/sellers, identical products, free entry/exit, perfect information; firms are price takers earning zero economic profit long-run. Positive economics describes 'what is' using facts and testable statements, while normative economics involves 'what ought to be' based on opinions and value judgments. GDP measures the total market value of all final goods and services produced within a country's borders in a given period.

Question 9 Economics

What is marginal analysis?

The law of supply states that, ceteris paribus, as the price of a good rises, the quantity supplied increases. Aggregate supply shows total output firms produce at different price levels; short-run AS slopes up, long-run is vertical. Marginal analysis compares marginal benefits and costs of decisions; rational choices occur where MB = MC. A monopoly is a market with one seller, high barriers to entry, price-setting power; it produces less and charges more than competitive markets.

Question 10 Economics

Define monetary policy.

The Federal Reserve conducts U.S. monetary policy, supervises banks, maintains financial stability, and provides banking services. Perfect competition features many buyers/sellers, identical products, free entry/exit, perfect information; firms are price takers earning zero economic profit long-run. Monetary policy is the central bank's actions to control money supply and interest rates to achieve goals like stable prices and full employment. Microeconomics studies individual markets, households, and firms, while macroeconomics examines the economy as a whole, including growth, inflation, and unemployment.

Question 11 Economics

Explain the tragedy of the commons.

The unemployment rate is the percentage of the labor force without jobs but actively seeking work. The tragedy of the commons occurs when individuals overuse shared resources (e.g., fisheries) due to no private incentives to conserve. The Phillips curve shows an inverse short-run relationship between unemployment and inflation rates. Tools include open market operations (buy/sell bonds), discount rate, and reserve requirements to influence money supply and interest rates.

Question 12 Economics

What is a monopoly?

Changes in income, tastes, prices of related goods (substitutes/complements), expectations, or number of buyers shift the demand curve; price changes cause movement along the curve. Inflation is a sustained increase in the general price level of goods and services over time, eroding purchasing power. A monopoly is a market with one seller, high barriers to entry, price-setting power; it produces less and charges more than competitive markets. Producer surplus is the difference between what producers receive and their minimum willingness to sell, shown by the area below the equilibrium price and above the supply curve.

Question 13 Economics

What is scarcity?

CPI measures the average change in prices paid by urban consumers for a market basket of goods and services. Scarcity refers to the fundamental economic problem that resources are limited while human wants are unlimited, forcing choices about resource allocation. Marginal analysis compares marginal benefits and costs of decisions; rational choices occur where MB = MC. Changes in input prices, technology, number of sellers, expectations, or government policies (taxes/subsidies) shift the supply curve; price changes cause movement along it.

Question 14 Economics

Describe business cycles.

Consumer surplus is the difference between what consumers are willing to pay and what they actually pay, represented by the area above the equilibrium price and below the demand curve. Business cycles are fluctuations in economic activity: expansion, peak, contraction (recession), trough. In floating exchange rates, supply and demand for currencies determine value, influenced by trade, interest rates, and speculation. The law of supply states that, ceteris paribus, as the price of a good rises, the quantity supplied increases.

Question 15 Economics

What is the law of demand?

The law of demand states that, ceteris paribus, as the price of a good rises, the quantity demanded falls, illustrated by a downward-sloping demand curve. Contractionary fiscal policy decreases spending or raises taxes to cool an overheating economy and curb inflation. A PPF is a curve showing the maximum possible output combinations of two goods or services an economy can produce with available resources and technology. Points inside indicate inefficiency; outside are unattainable. The natural rate is frictional plus structural unemployment at full employment, excluding cyclical effects.

Fiscal policy involves government spending and taxation to influence the economy, managed by Congress and the executive.

Question 17 Economics

What is monopolistic competition?

A monopoly is a market with one seller, high barriers to entry, price-setting power; it produces less and charges more than competitive markets.

Question 18 Economics

What causes demand-pull inflation?

Nominal GDP uses current prices; real GDP adjusts for inflation using base-year prices to measure actual output changes. Demand-pull inflation occurs when aggregate demand exceeds supply, pulling prices up, often from increased spending.

Question 22 Economics

What is a price ceiling?

A price ceiling is a legal maximum price set below equilibrium, often causing shortages as quantity demanded exceeds quantity supplied. Public goods are non-excludable and non-rivalrous, like national defense; markets underprovide them, requiring government intervention. The law of supply states that, ceteris paribus, as the price of a good rises, the quantity supplied increases. Microeconomics studies individual markets, households, and firms, while macroeconomics examines the economy as a whole, including growth, inflation, and unemployment.

Question 23 Economics

What is aggregate demand (AD)?

Externalities are unintended side effects of production/consumption on third parties: positive (benefits) or negative (costs). An oligopoly has few interdependent sellers dominating the market, often leading to collusion or strategic behavior like price wars.
