Essential Questions

What are the components of gross investment?

Posted on April 16, 2014 at 10:50 AM Comments comments (0)

In economics courses, investment generally refers to business expenditures on capital goods. There are three components to gross investment when calculating the gross domestic product:


1. Fixed investment on capital goods (tools, machinery)

2. Residential and nonresidential investment (houses, apartments, stores)

3. Adjustments to inventories (accounting for unsold goods produced in the current year)


Net Investment = Gross Investment - Depreciation (AKA Consumption of Fixed Capital)

How do you calculate the real interest rate?

Posted on April 16, 2014 at 10:45 AM Comments comments (0)

To calculate the real or nominal interest rate, we can use the Fisher equation. The real interest rate accounts for changes in the price level and is very important for businesses interested in investment spending. When real interest rates are low, businesses will increase spending. When real interest rates are high, businesses are less likely to invest.


Real Interest Rate = Nominal Interest Rate - Inflation Rate

(or)

Nominal Interest Rate = Real Interest Rate + Inflation Rate

How do you calculate the inflation rate?

Posted on April 16, 2014 at 10:35 AM Comments comments (0)

The inflation rate measures the percentage increase in consumer prices over a period of time. To calculate the inflation rate, we use a consumer price index (CPI). The consumer price index tracks the prices of goods and services that the typical household buys using a market basket sample (CPI = Market Basket of Specific Year / Market Basket of a Base Year).


The No Bull Review diagram below shows the formula for calculating the inflation rate when you have the CPIs.

What is real GDP per capita?

Posted on April 16, 2014 at 10:30 AM Comments comments (0)

Real GDP per capita is one way to measure economic growth and a nation's general economic well-being. It represents the output per person within an economy.


Real GDP per capita = Real GDP / Population

What is the difference between real GDP and nominal GDP?

Posted on April 16, 2014 at 10:20 AM Comments comments (0)

Real GDP is output that has been adjusted to hold the price level constant. This way we can measure the level of goods and services that are produced over a period of time without worrying about changes in the price level.


Nominal GDP has not been adjusted for changes in the price level and reflects the market value of all goods and services in the year everything was produced.


 

Therefore, real GDP is more important than nominal GDP for measuring economic growth.


How to calculate the Real GDP:

Real GDP = Nominal GDP / GDP Price Index

What is the difference between demand-pull inflation and cost-push inflation?

Posted on April 16, 2014 at 10:10 AM Comments comments (0)

Demand-pull inflation is caused by an increase in aggregate demand. This means that buyers are pulling up the general price level of goods and services within an economy.


Cost-push inflation is caused by a decrease in short-run aggregate supply. This means that an increase in production costs (resource prices) have caused an increase in the general price level.

What is a business cycle?

Posted on April 16, 2014 at 10:05 AM Comments comments (0)

The business cycle shows the upturns and downturns of economic activity. It contains four parts:


1. Expansions (real GDP increases, unemployment falls)

2. Peaks (real GDP is at its max, resources are fully employed)

3. Contractions (real GDP declines, unemployment rises)

4. Troughs (real GDP is at its lowest point, unemployment is near its highest point)


The No Bull Review diagram below illustrates the four key parts along with an upward sloping line which demonstrates the long term trend of economic growth.

What are the three types of unemployment?

Posted on April 16, 2014 at 9:55 AM Comments comments (0)

There are three types of unemployment that make up the rate of unemployment in a given economy.


1. Frictional unemployment (temporary, seasonal): includes recent graduates and people who quit their job to find something better.

2. Structural unemployment (skills no longer needed): includes people who are replaced by technology or new industries (creative destruction). These people need to retrain or move to find work.

3. Cyclical unemployment (due to recession): includes people who are laid off because the economy is weak (downturn in the business cycle).


This No Bull Review video discusses the three types of unemployment and the natural rate of unemployment.

How do you calculate the unemployment rate?

Posted on April 14, 2014 at 4:20 PM Comments comments (0)

The unemployment rate measures the percentage of people in the labor force that are actively looking for employment.


To calculate the rate of unemoployment, take the number of people that are unemployed and looking for work and divide by the number of people that are working plus the number of people looking for work.


Unemployment Rate = Quantity of people unemployed / Quantity of people in the labor force
