Economists predict economic performance by studying past and current performance of the economy. They use measures to track such things as: What's the total economic output of the country? How much money did businesses and individuals make last year, and are they making more this year? Are prices for things going up or down? How many people are working and how many are looking for work?
Let’s take a look at some of the tools economists use to measure these statistics. You may have heard of some of these measures in the news, but didn't know what they were, or how they were used.
Economists use the following indicators to measure the economic performance of countries:
All of these measurements are reflected in the business cycle, which is the movement, whether upward or downward, of economic activity in a nation. Let's look at each of the measurements of economic activity in-depth first. Once you understand how economists use these tools, we'll look at how they all fit together in the business cycle. Once you're done with these presentations and practices, you'll understand how all these numbers have a concrete impact on your life.

The Business Cycle
As you already learned, consumers decide whether or not to buy something based on how secure they feel about the economy. For example, if they constantly hear on the news that the nation is in a recession and people are losing jobs, they feel less secure about their finances due to a weak economy, and thus are less likely to make a lot of purchases. This in turn will make the economy even weaker. On the other hand, if consumers are confident the economy is doing well, they will buy more, and make the economy grow.
Take a moment to read the following scenarios. Which situation would make you want to spend more money?
Scenario A | Scenario B |
---|---|
You work in an electronics store and your supervisor congratulates you on having a twenty percent increase in your sales since last year. As a result you get more hours, and you notice the store is having difficulty keeping its shelves stocked. | You work in a retail store, and your supervisor meets with you to explain how sales are down thirty percent since last year. As a result every employee's hours will be cut back. |
In Scenario A, consumer confidence is spreading. You are therefore more likely to have high economic confidence and buy more. The more consumers buy, the more economic growth will occur - this contributes to consumers buying even more products. In Scenario B, consumer confidence is decreasing. You are therefore less likely to have economic confidence and buy less. Companies will be forced to lay off employees, and this lack of confidence will spread as fewer and fewer people buy goods.
Phases of the Business Cycle
As demonstrated by the above scenarios, consumer confidence can cause changes in the economy. Neither positive nor negative changes will go on forever. Rather, it's a cycle commonly referred to as the business cycle. In this interactivity, you will examine a hypothetical business cycle. As you explore the phases, think about how the business cycle is like a roller coaster. Click the player button to begin.
