Surprise!! Prices Have Been Falling For Years

I wonder how many people in countries like Switzerland, Brazil, Canada, Russia, and China, and the United States would be surprised to learn that prices of products and services in their countries have become much less expensive over the years.
Say what? You must be crazy, you say! Prices are rising way too fast!
Yes, most citizens see their purchases as becoming more expensive when, in actuality, things are becoming less expensive. Of course, the paradox is that although nominal prices (the actual price tag) are, in fact, increasing, nominal income (the average wage or salary) has been growing faster. This is a topic that in economics is called “real income” or a measurement that compares a nation’s income growth relative to the growth in prices that the same income buys.
Let’s take some specific facts for the United States:
In the United States real median household income grew from $41,318 to $50,811 from 1970 through 2006 for a total percentage gain of 23% (source: Pew Research Center). Both of the aforementioned median household incomes are stated in 2008 or current dollars which makes the comparison valid. Median household income is an attempt to quantify the progress that the “middle American” family or typical family has made. So, in short, the median household in America can buy 23% more with their income today than they could in 1970. In other words, relative prices are lower to income.
If we look at the same United States income data over the same period for real average household income, there is real income growth of nearly 60%. The higher growth (60%) in real incomes for the average household versus the median (middle) growth rate (23%) is explained by the fact that much of the growth in United States’ real incomes has accrued disproportionately to the college educated & entrepreneurs driving up real income growth rates much faster for the average than the median or middle household. (Hint: continue your education!)
Now let’s get back to the main premise of the title of this blog and the opening assertion that prices are lower than ever. What we are really saying is that you have to benchmark price increases to income increases to really understand whether things are becoming more expensive. The vast majority of products & services are cheaper today in all nations than they have ever been before, which helps explain, excluding the effects of the current recession, why more citizens than ever before can afford to own their own houses, drive more and better cars, and are likely to have cable, cell phones, and computers. The reason we are led to believe differently is because we are victims of our own human nature, which often causes us to focus on the problem areas (rising prices) and not the benefits (incomes that are rising faster). Most citizens’ focus expands out to the last dollar of their incomes and they quickly notice those select products that are rising faster than others like health care, gasoline prices, and education! Hey, even gasoline prices are not at an all relative price high. If gasoline prices in the United States are restated for inflation, or set to comparable 2009 dollars, they are $2.60 per gallon today vs. $3.17 in 1981 and $3.50 in 1918!
Now, you may say to yourself that statistics can lie or mislead and you are sure in your gut that things are getting more expensive relatively. You can try to validate that incorrect “gut feeling” by examining whether your country’s middle class is enjoying less or more products and services. “Real income” really is just a measurement of the quantity and quality of products and services that you have. For example, the average American household has larger homes, more cars, more air conditioning, more gadgets, and better healthcare & prescription drugs than, say, 20 years ago.
But let’s end this blog with a concern. Although everything noted above is accurate, the pace of real income growth has been relatively slow over the last 10 years, especially for the middle class in the United States. Most of that growth in real income mentioned above has occurred up until this current decade. For the last 10 years, median family income growth in the U.S. has been very small and the average income growth has been higher but below the U.S. historical experience. There are many reasons for this slowdown in real income growth, but three big reasons are that

1. the U.S. has now had two recessions this decade (2001 and 2007-current, versus our historical average of only 1 per decade), and
2. energy and health care prices have risen much faster, and
3. foreign labor competition and technology advancement has kept the uneducated/unskilled U.S. workers real income relatively stagnant. More than ever before, a good education is the ticket to your economic future!

Discussion Questions:

1. Inflation is bad, right? Well, what if average prices rise by 2% a year but average incomes rise by 3%. What happens to real income in this situation? Is the average household better or worse off in such a scenario?
2. How have trade and globalization contributed to rising real wages in America and Swizerland?
3. How have trade and globalization contributed to falling nominal wages in America and Switzerland?
4. How do improvments in technology contribute to rising real wages in both developed and developing economies? What about health and education?
5. What types of policies can government pursue to help raise the real wages of the nation’s workers?

GDP Made Simple

Just a few weeks ago, the U.S. Government’s Commerce Department provided its first estimate of the country’s 3rd quarter (July-September 2009) gross domestic product or GDP, announcing an estimated annualized quarter over quarter growth of 3.5%. GDP reports are of special interest to countries since they provide an important macroeconomic measurement of how much an economy’s goods & services supply and income has grown, or recessed, compared to the last three calendar months.
Let me try and make the concept of GDP easy to understand and why it is considered perhaps the most important, single macroeconomic measurement.
GDP is simply a calculation that measures the market value (final price) of all the final goods and services produced within the borders of our country. Thus, U.S. GDP includes Toyotas produced in Alabama but excludes Cadillac’s made in Canada. GDP includes all U.S. exports but excludes all U.S. imports since imports, by definition, imports are produced in some other country and are a more direct employment benefit of the foreign country’s GDP.
If you think about it, ultimately our country’s economic satisfaction is best measured by the goods and services that are produced and that we have access to, which is why GDP is the measurement that is synonymous with “economic growth” or growth in goods & services for its citizens. In addition, rising GDP (more goods and services) is the ultimate economic goal of any economy which can best be accomplished through the means of the two other key macroeconomic measurements of employment and productivity, which are not the subject of this particular blog.
Let’s describe how the GDP calculation is made. Each quarter, the Government compares the final value of the domestic goods produced and services rendered in the current quarter to the final value of the goods produced and services rendered in the previous quarter. The calculation then takes the percentage gain, current quarter versus previous quarter, and annualizes the percentage. The comparison is always restated for inflation so that the figures are comparable from one period to the next. For purists, we call this “real GDP” which is the only GDP reported by the media, even though the word “real” is almost always dropped to avoid confusion with the average citizen. For example, the third quarter 2009 U.S. GDP report highlighted a 3.5% GDP annualized growth rate. This means that the second quarter final value of goods and services produced was approximately .87% or 3.5%/4.
Now let me get to my favorite point on GDP, which even many economists lose sight of. GDP growth is precisely the same as income growth! For example, in the second quarter of 2009 we can say that incomes for American households and American citizens grew by 3.5% restated for inflation. Said another way, our country’s purchasing power grew by 3.5% which represents the income to produce the increasing supply of goods and services. You probably never thought about it this way but every time you purchase something, every dollar you spend is going to someone as income, whether it is the workers as wages or benefits, the landlords as rent, a bank that has made a loan as interest income, or to the owners of the business as profits. I tell my students that Real GDP = Real Income and the only question is how that real income is dispersed among owners (profits), workers (employee wages and benefits), lenders (interest), and lessors (rent). Many citizens are unaware that the Government calculates GDP both in terms of the final market value of the goods and services PRODUCED (the “expenditure method”, which is the version that the media uses, as well as how that same production value under the “expenditure method” translates to higher incomes in a GDP version called the “income method”.
I find the preceding paragraph, GDP = Income, to be a break through moment for a lot of citizens, or first time economic students, in truly understanding the value of the GDP measurement. It is easier for most to think in terms percentage growth in income in lieu of a fuzzier wording like GDP percentage growth. Most citizens are surprised to find that our national incomes or GDP, restated for inflation, increased by 17.4% from 2000 – 2007, just prior to the onset of this current recession. This 7-year growth rate in GDP or incomes still equates to a below average historical average performance. More specifically, over the last 7 years our average annual GDP or income growth rate was only 2.2% versus our historical average growth rate of 3.2%. However, the final point of caution is that the GDP or income growth rate is a collective average, thus the growth in GDP or incomes does not indicate how those income gains are accruing to the various socioeconomic classes or professions. That is also a topic of a future blog on “income distribution” or equality.
Discussion Questions:

1. Have you ever thought about substituting the word “income” for “GDP” to understand GDP more simply? Why are the concepts of income and GDP inter-changeable?
2. Which four groups earn the income generated by the production of goods and services?
3. Although GDP has still risen this decade, despite the current severe recession, many analyses show that our nation’s middle class has made virtually no real income gains this decade. How could this be so if GDP = Income and our GDP has grown this decade?

Booms and Busts - The Business Cycle

 Share

The business cycle is an economic phenomenon which describes changes in the level of economic output compared to a long run average. A simple set of data illustrating the business cycle is shown below. The level of Real GDP in most countries increased by a positive rate each year from 2000 – 2008, before the Global Financial Crisis caused the most significant recession and then recovery in recent history.

In Macroeconomics we can model changes in the level of economic activity using the Aggregate Demand and Aggregate Supply model. This theoretical idea is shown on the following diagram, which explains the link between the business cycle and the level of aggregate demand and aggregate supply in the economy.
When the actual GDP line is above the potential GDP line the economy is said to have a positive output gap as at the peak point. Aggregate Demand exceeds the potential capacity thus shortages occur and prices rise (inflation) also called an inflationary gap. Factors of production such as labor, land and capital are fixed in the short run, and wages can not change. Therefore the inflationary gap will remain in the short run.

When the actual GDP line is below the potential GDP line the economy has a negative output gap as in a recession. At this point there is spare capacity, higher then average unemployment leading to less inflationary pressures in the aggregate economy.  Also called a recessionary gap. We can relate this concept back to the Real GDP data, which explains a dramatic fall in the level of economic activity in 2009.
Each of these two simple scenarios is caused by changes in Aggregate Demand. As we studies last week, changes in Aggregate Demand can be caused by a variety of factors which influence each component

Components of Aggregate Demand (AD)
C – Consumer Spending
I – Investment
G – Government Spending
(X-M) – Net Export Receipts

The two following videos highlight changes to the level of Aggregate Demand and the resulting inflationary and recessionary gaps. The first video explains how the Chinese government is boosting aggregate demand by increasing government spending and investment. It is a likely response to boost economic activity, and to reduce unemployment.
The second video is a quick look at the UK government budget. A government budget explains the countries spending and taxation decisions for the coming year. The UK was forced to reduce government spending due to the countries very high levels of public debt. The UK has been forced to borrow money to pay for current spending, which increases the nations debt to the rest of the world.

Discussion Questions and Activities:

1. Explain any changes to Aggregate Demand that would result in an inflationary gap occurring?
2. When a country is experiencing an inflationary gap, what happens to price levels and the level of unemployment?
3. Video 1: What are the impacts on level of economic activity due to the government investment? Evaluate if you think this is an effective form of investment.
4. Video 2: The UK government is planning to increase VAT tax rates and decrease spending on national defence. Explain the likely effect of the level of economic activity (Real GDP), unemployment and the price level using the AD/AS model.
5. In your notes draw an AS/AD model to explain the impacts of the events shown in each video. Be careful to fully label each diagram with any changes.
