Core Concepts Covered
Before diving into the details, let’s take a brief look at the core topics that will be covered in this AP Macro cheat sheet. Think of this as a roadmap, guiding you through the key areas of study:
- Basic Economic Concepts: This foundational section lays the groundwork for understanding the entire course. We’ll explore concepts like scarcity, opportunity cost, and the production possibilities curve.
- National Income and Price Determination: Here, we’ll delve into how national income is measured, the factors that influence aggregate supply and demand, and the determinants of price levels.
- The Financial Sector: This section examines the role of money, banking, and the Federal Reserve in shaping the economy.
- Stabilization Policies: We’ll explore the tools that governments and central banks use to stabilize the economy, including fiscal and monetary policy.
- Economic Growth: This section examines the factors that drive long-term economic growth and the policies that can promote it.
- International Trade and Finance: Finally, we’ll delve into the world of international trade, exchange rates, and the balance of payments.
Basic Economic Concepts
Economics, at its heart, is about making choices in the face of scarcity. Scarcity means that our wants and needs are unlimited, but the resources available to satisfy them are finite. This fundamental constraint forces us to make choices, and every choice has an *opportunity cost*. The opportunity cost is the value of the next best alternative that you give up when making a decision.
The *Production Possibilities Curve (PPC)* is a graphical representation of the trade-offs involved in allocating resources between two goods. It shows the maximum amount of each good that can be produced, given the available resources and technology. Points inside the PPC represent inefficient use of resources, while points outside the PPC are unattainable with current resources.
When discussing production, it’s important to distinguish between *absolute advantage* and *comparative advantage*. Absolute advantage refers to the ability to produce more of a good or service than another producer, using the same amount of resources. *Comparative advantage*, on the other hand, refers to the ability to produce a good or service at a lower opportunity cost than another producer. Comparative advantage is the basis for trade.
The *Circular Flow Model* provides a simplified representation of the flow of goods, services, and money between households and firms in an economy. It highlights the interdependence between these two groups and the role of markets in coordinating their activities.
National Income and Price Determination
*Gross Domestic Product (GDP)* is the most widely used measure of national income. It represents the total market value of all final goods and services produced within a country’s borders during a specific period of time. GDP can be calculated using the expenditure approach, which sums up consumption (C), investment (I), government spending (G), and net exports (NX): GDP = C + I + G + NX.
It’s important to distinguish between *nominal GDP* and *real GDP*. Nominal GDP is measured in current prices, while real GDP is adjusted for inflation. Real GDP provides a more accurate measure of economic growth. The *GDP deflator* is a measure of the overall price level in the economy and can be used to calculate the percentage change in the overall price level.
The *Aggregate Supply (AS) and Aggregate Demand (AD) model* is a powerful tool for analyzing macroeconomic fluctuations. The AD curve shows the relationship between the overall price level and the quantity of goods and services demanded in the economy. The AS curve shows the relationship between the overall price level and the quantity of goods and services supplied in the economy. The intersection of the AD and AS curves determines the *equilibrium* price level and output.
The AS curve has two distinct sections: the short-run aggregate supply (SRAS) curve and the long-run aggregate supply (LRAS) curve. The SRAS curve is upward sloping, reflecting the fact that firms can increase output in the short run by using existing resources more intensively. The LRAS curve, on the other hand, is vertical, reflecting the fact that in the long run, output is determined by the economy’s productive capacity, not by the price level.
*Fiscal policy*, which involves changes in government spending and taxes, can be used to influence aggregate demand. Expansionary fiscal policy (increased government spending or lower taxes) shifts the AD curve to the right, leading to higher output and prices. Contractionary fiscal policy (decreased government spending or higher taxes) shifts the AD curve to the left, leading to lower output and prices.
The Financial Sector
*Money* serves as a medium of exchange, a unit of account, and a store of value. *Fractional reserve banking* is the system in which banks are required to hold only a fraction of their deposits in reserve, lending out the rest. This system allows banks to create money through the *money multiplier* effect. The money multiplier is calculated as one divided by the reserve requirement.
The *Federal Reserve (The Fed)* is the central bank of the United States. It plays a crucial role in regulating the money supply and maintaining the stability of the financial system. The Fed has several tools at its disposal, including *open market operations* (buying and selling government bonds), the *discount rate* (the interest rate at which banks can borrow directly from the Fed), and the *reserve requirement* (the fraction of deposits that banks are required to hold in reserve).
The *Money Market* illustrates the supply and demand for money, determining the nominal interest rate. Changes in the money supply or the demand for money can affect the interest rate, which in turn affects investment and aggregate demand.
The *Fisher Equation* shows the relationship between nominal interest rates, real interest rates, and inflation: Nominal Interest Rate = Real Interest Rate + Inflation. The *Loanable Funds Market* illustrates the supply and demand for loanable funds, determining the real interest rate.
Inflation, Unemployment, and Stabilization Policies
*Inflation* is a sustained increase in the overall price level. *Demand-pull inflation* occurs when there is too much money chasing too few goods. *Cost-push inflation* occurs when there is an increase in the costs of production.
The *unemployment rate* measures the percentage of the labor force that is unemployed and actively seeking work. There are different types of unemployment, including *frictional unemployment* (occurs when people are temporarily between jobs), *structural unemployment* (occurs when there is a mismatch between the skills of workers and the requirements of available jobs), and *cyclical unemployment* (occurs during recessions).
The *Phillips Curve* shows the inverse relationship between inflation and unemployment in the short run. However, in the long run, the Phillips Curve is vertical at the natural rate of unemployment.
Both *fiscal policy* and *monetary policy* can be used to stabilize the economy. *Government spending* and *taxes* make up fiscal policy. Expansionary fiscal policy aims to boost the economy, while contractionary fiscal policy aims to slow it down. *Monetary policy* involves manipulating the money supply and interest rates. Expansionary monetary policy aims to lower interest rates and increase the money supply, while contractionary monetary policy aims to raise interest rates and decrease the money supply.
*Crowding out* occurs when government borrowing leads to higher interest rates, which in turn reduces private investment.
Economic Growth
*Economic growth* refers to an increase in the production of goods and services over time. It’s driven by factors such as technological progress, increased resources, and improved human capital. The *Production Function* shows the relationship between inputs (labor, capital, resources) and output. Policies that promote technological innovation, education, and investment in capital can foster economic growth.
International Trade and Finance
The *Balance of Payments* tracks all transactions between a country and the rest of the world. It consists of two main accounts: the current account (which includes trade in goods and services, as well as income and transfers) and the financial account (which includes investments).
*Exchange rates* determine the value of one currency relative to another. An *appreciation* of a currency means that it becomes more valuable relative to other currencies, while a *depreciation* means that it becomes less valuable. Exchange rates affect *net exports* and the balance of payments.
