AP Macro Cheat Sheet 2020: Your Ultimate Study Guide
When it comes to conquering AP Macroeconomics in 2020, having a reliable cheat sheet isn't about cheating on the exam—it's about having a concise, mentally organized framework that encapsulates the entire curriculum. This AP Macro cheat sheet 2020 is designed to distill complex economic concepts into digestible, memorable points, ensuring you can recall key terms, formulas, and relationships under pressure. Let's dive into the core components that every student needs to master.
Foundational Concepts and Key Definitions
Macroeconomics begins with understanding the broader picture. Start by wrapping your head around Gross Domestic Product (GDP), the total market value of all final goods and services produced within a country's borders in a given period. Distinguish between Nominal GDP (current prices) and Real GDP (adjusted for inflation). Inflation itself, a sustained increase in the general price level, is tracked via the Consumer Price Index (CPI). The Unemployment Rate, identified through surveys like the Household Survey, measures the percentage of the labor force actively seeking but unable to find employment. Crucially, grasp the distinctions between frictional, structural, and cyclical unemployment—a favorite topic for multiple-choice questions.
AD/AS Model: Shifts vs. Movements. This is non-negotiable. A change in the price level of all goods in the economy (causing movement along the curve) is distinct from a change other factors (causing a shift of the entire curve). For Aggregate Demand (AD), shifts are triggered by changes in consumption, investment, government spending, or net exports. Aggregate Supply (AS) shifts due to changes in resource prices, technology, or expectations.
The Core Models: AD/AS and the Money Market
The Aggregate Demand-Aggregate Supply (AD/AS) model is the backbone of your AP Macro graphing. A recessionary gap occurs when Real GDP is below potential GDP, often linked to high unemployment. An inflationary gap indicates Real GDP has surpassed potential, leading to demand-pull inflation. The Multiplier Effect is crucial here: an initial change in spending (like government investment) leads to a magnified increase in GDP. The Money Market graph, where the interest rate is on the vertical axis and the quantity of money on the horizontal, illustrates how the Federal Reserve's actions influence borrowing costs and, ultimately, the broader economy. An increase in the money supply (via open market purchases or lowering the reserve requirement) lowers the interest rate, stimulating investment and shifting AD to the right.
Fiscal and Monetary Policy Levers
Fiscal policy, controlled by the government, involves changes in taxation and spending. Expansionary fiscal policy (increasing G or decreasing T) aims to close a recessionary gap by boosting Aggregate Demand. Conversely, contractionary fiscal policy combats inflation. The Federal Reserve implements monetary policy. Expansionary monetary policy (lowering the federal funds rate or buying bonds) increases the money supply, lowering interest rates and encouraging investment. Understanding the transmission mechanism—how Fed actions ripple through the economy—is essential. Remember the relationship between bond prices and interest rates: when the Fed buys bonds, bond prices rise, and interest rates fall, further fueling investment.
Multiplier, Rules, and International Trade
Don't overlook the spending multiplier. This concept explains how an initial injection of government spending results in a magnified change in GDP. Furthermore, the Phillips Curve shows the short-run trade-off between inflation and unemployment, though long-run expectations can shift this curve. Regarding international trade, appreciate how exchange rates are determined by supply and demand in the foreign exchange market. A stronger domestic currency makes exports more expensive and imports cheaper, impacting net exports and AD. The balance of payments summarizes all economic transactions between a country and the rest of the world, encompassing the current account (goods/services) and financial account (assets).
Formulas and Quick Review
- Spending Multiplier = 1 / (1 - Marginal Propensity to Consume)
- GDP = C + I + G + (X - M)
- Unemployment Rate = (Unemployed / Labor Force) * 100
- Real Interest Rate = Nominal Interest Rate - Inflation Rate
