Key Concepts and Formulas (Cheat Sheet Section)

Let’s delve into the core content that should populate your AP Macro *cheat sheet*. Remember, the goal is to distill the most important information into a concise and easily accessible format. The following sections outline the areas you should cover, and how to best present the information.

Basic Economic Concepts

At the heart of macroeconomics lie fundamental economic concepts. These are the building blocks upon which all other principles are based.

Scarcity and Opportunity Cost: Begin by solidifying your understanding of scarcity, the fundamental economic problem. Highlight that resources are limited, forcing us to make choices. Define opportunity cost – the value of the next best alternative forgone. Include example scenarios such as a student choosing between going to class versus working at a job.

Production Possibility Frontier (PPF): Illustrate the PPF visually, explaining how it represents the maximum possible combinations of two goods or services that an economy can produce with its available resources. Clearly label the concepts of efficiency (points on the curve), inefficiency (points inside the curve), and unattainable points (points outside the curve). Explain the effects of economic growth on the PPF. Include the formula for calculating opportunity cost from a PPF.

Supply and Demand: This is a cornerstone of microeconomics which is essential for Macroeconomics. The laws of supply and demand will assist your understanding of the AP Macro questions. Include diagrams of supply and demand curves, clearly labeling the axes (price and quantity). Emphasize the factors that shift both the supply and demand curves, such as changes in consumer income, tastes, expectations, the price of related goods, input costs, and the number of sellers. Show how these shifts lead to changes in equilibrium price and quantity.

Elasticity: Include a concise summary of price elasticity of demand, price elasticity of supply, income elasticity of demand, and cross-price elasticity of demand. Provide the formulas for calculating each type of elasticity. Explain what the different elasticity values (e.g., elastic, inelastic, unit elastic) mean and their implications. Include examples of each.

Circular Flow Model: Draw the circular flow model, clearly illustrating the flow of goods, services, and money between households and firms. Explain the roles of factor markets (where factors of production are exchanged) and product markets (where goods and services are exchanged). Include a visual representation.

National Income and Price Determination

Understanding how to measure a nation’s economic performance and how prices are set is vital for success.

Gross Domestic Product (GDP): Define GDP as the total market value of all final goods and services produced within a country’s borders in a specific time period (typically a year). Outline the different approaches to calculating GDP: the expenditure approach (GDP = C + I + G + NX), the income approach, and the output approach. Explain the components of the expenditure approach (Consumption, Investment, Government Spending, Net Exports). Explain the difference between nominal and real GDP and how to calculate them. Explain the GDP deflator.

Inflation: Define inflation as a sustained increase in the general price level. Explain how to calculate the Consumer Price Index (CPI). Give the formula for calculating the inflation rate, and provide the formula to determine the percentage change. Discuss the different types of inflation: demand-pull inflation (caused by excess demand) and cost-push inflation (caused by rising production costs). Discuss the effects of inflation, including the distribution of income.

Unemployment: Define unemployment, and describe the Labor Force. Define the unemployment rate and the labor force participation rate and their corresponding formulas. Explain the different types of unemployment: frictional (short-term unemployment from job transitions), structural (mismatch between worker skills and available jobs), and cyclical (unemployment due to economic downturns). Explain the relationship between unemployment and the business cycle.

Business Cycles: Describe the different phases of the business cycle: expansion (growth), peak (highest point), contraction (recession), and trough (lowest point). Discuss the characteristics of each phase and their impact on economic variables like employment, inflation, and output.

Financial Sector

The financial sector plays a pivotal role in the overall economy.

Money Supply: Define money and discuss the different measures of the money supply (M1, M2). Explain the components of each measure.

The Money Market: Illustrate the money market with a graph, showing the supply of money (vertical line, controlled by the central bank) and the demand for money (downward-sloping). Explain what determines the demand for money, and what factors shift the demand and supply curves. Show how changes in interest rates affect the money market.

The Loanable Funds Market: Illustrate the loanable funds market, showing the supply of loanable funds (typically upward-sloping, from savings) and the demand for loanable funds (typically downward-sloping, from borrowing). Discuss the factors that affect the supply and demand of loanable funds. Explain how the equilibrium interest rate is determined in this market.

Banking: Explain the concept of fractional reserve banking. Explain the role of the central bank and its influence on the money supply. Explain reserve requirements. Show how the money multiplier works and provide the formula.

Stabilization Policies

Governments and central banks use stabilization policies to influence the economy.

Fiscal Policy: Define fiscal policy as the use of government spending and taxation to influence the economy. Explain expansionary fiscal policy (increasing government spending or decreasing taxes) and contractionary fiscal policy (decreasing government spending or increasing taxes). Discuss the impact of fiscal policy on aggregate demand, output, employment, and the price level. Explain the concept of the multiplier.

Monetary Policy: Define monetary policy as the use of the money supply and interest rates to influence the economy. Describe the tools of monetary policy: reserve requirements, the discount rate, and open market operations. Explain how each tool works. Explain expansionary monetary policy (increasing the money supply, lowering interest rates) and contractionary monetary policy (decreasing the money supply, raising interest rates). Discuss the impact of monetary policy on aggregate demand, output, and the price level.

Aggregate Demand-Aggregate Supply (AD-AS) Model: Draw the AD-AS model, illustrating the aggregate demand curve (downward sloping), the short-run aggregate supply curve (upward sloping), and the long-run aggregate supply curve (vertical). Explain the factors that shift the AD and AS curves. Show how the model is used to analyze the impact of fiscal and monetary policies. Explain short-run and long-run equilibrium.

International Trade and Finance

Global interconnectedness is a crucial aspect of modern economies.

Balance of Payments: Define the balance of payments as a record of all economic transactions between a country and the rest of the world. Explain the components of the balance of payments: the current account (trade in goods and services, investment income, and transfers) and the capital account (investment flows). Explain how surpluses and deficits in the current account can be financed.

Exchange Rates: Define exchange rates and explain how they work. Explain the concepts of currency appreciation and depreciation. Discuss the factors that influence exchange rates, such as interest rate differentials, inflation rates, economic growth rates, and speculation.

Trade Barriers: Define trade barriers, such as tariffs and quotas. Explain the effects of tariffs and quotas on prices, quantities, and trade. Explain the concept of free trade and its benefits.

Economic Growth

Understanding the factors that drive long-run economic growth is critical.

Productivity: Define productivity as output per worker or output per hour. Explain the factors that influence productivity, such as technological advancements, investment in capital, and human capital.

Determinants of Economic Growth: Identify the key factors that drive economic growth: technological progress, increased capital investment, human capital accumulation (education and skills), and institutional factors (property rights, the rule of law, stable political environment).

Tips for Using the Cheat Sheet Effectively

Simply creating an AP Macro *cheat sheet* is not enough. You need to know how to utilize it effectively.

How to Create Your Own Cheat Sheet:

Personalization is key. Don’t just copy information from a textbook. Rewrite definitions in your own words and use diagrams and tables that you understand.

Prioritize essential information. Focus on the core concepts, formulas, and definitions that you find most challenging or are most frequently tested.

Organize logically. Use clear headings, subheadings, and bullet points. Consider using color-coding or highlighting to make the information easier to find and remember. Use mnemonics to recall essential items.

Strategies for Exam Preparation:

Practice problems are your best friends. Work through numerous practice problems to apply the concepts you have learned and to get used to the exam format.

Flashcards help to memorize the key terms. Create flashcards with definitions, formulas, and important diagrams.

Form study groups. Discuss concepts with classmates, quiz each other, and work through practice problems together.

Time management in the exam:

Practice is vital. Take practice tests under timed conditions to simulate the exam environment.

Allocate time wisely. Develop a strategy for answering the multiple-choice questions and the free-response questions.

Start with what you know best. Tackle the questions you feel most comfortable with first, then come back to the more challenging ones.

Practice Problems and Examples

Let’s put theory into practice. Here are examples of the type of questions you can expect on the AP Macro exam.

Multiple-Choice Questions

Example 1: If the government increases spending, what is the most likely short-run effect? (A) Decrease in aggregate demand (B) Decrease in the price level (C) Increase in real GDP (D) Decrease in the unemployment rate

Answer: (C) Increase in real GDP. Government spending is a component of aggregate demand. An increase in government spending increases aggregate demand, which leads to an increase in real GDP.

Example 2: A country has a comparative advantage in the production of a good if it can produce that good at: (A) A higher opportunity cost than another country. (B) A lower opportunity cost than another country. (C) A higher price than another country. (D) A lower price than another country.

Answer: (B) A lower opportunity cost than another country.

Free Response Questions (FRQs)

Understanding the Structure: FRQs typically require you to apply economic concepts to real-world scenarios. They often involve analyzing graphs, explaining relationships, and providing recommendations based on economic principles.

Analyze the Prompts. Carefully read each part of the question and identify what the question is asking. Underline the keywords.

Use Clear Labels and Explanations Always clearly label all graphs, with appropriate curves and axes. Use definitions to explain the concepts being applied.

Answer Examples:

Scenario: Suppose the Federal Reserve decides to increase the money supply.

(a) Draw a correctly labeled graph of the money market and show the effect of this action on the interest rate.

(b) Explain the effects of the interest rate change on investment.

(c) Explain how this action will affect output, employment, and price levels.
