Lesson Plan: Sources of Economic Growth and Development

Introduction: In order to understand the goals of economic development, it is useful to examine the characteristics of more economically developed countries and compare them to those of less economically developed countries.

Resources:

Part 1 – Data collection: Using the two websites above, locate the following for TWO COUNTRIES, one from the list of countries with “high human development” and one from the list of countries with “low human development”. Use the tables below to fill in the data for the two countries you have chosen.

Social Indicators:

  • HDI ranking and value
  • Age structure
  • Population growth rate
  • School life expectancy
  • Life expectancy at birth
  • Total fertility rate
  • Education expenditures

Economic Indicators:

  • GDP per capita
  • GDP – composition by sector
  • Unemployment rate
  • Public debt
  • Stock of direct foreign investment – at home:
  • Labor force – by occupation

Social Indicators:

Country with low HDI

GDP per capita

GDP – composition by sector

Unemployment rate

Stock of direct foreign investment – at home:

Household income or consumption by percentage share:

Labor force – by occupation:

Part 2 – Dependency Ratio: A nation’s dependency ratio tells us something about the ability of members of a nation’s workforce to provide necessities to him or herself and his or her dependents. Typically, less economically developed nations will have a higher dependency ratio than more economically developed countries. The lower a nation’s dependency ratio, the greater capacity for its workers to accumulate savings, which leads to investment, accumulation of capital, greater productivity, higher incomes and more economic development.

Calculation the dependency ratio: To calculate a nation’s dependency ratio, you must find demographic information on its population. You may need to do additional research beyond the two websites above to find this data.

Calculate the dependency ratios for:

  1. Your country with high HD:
  2. Your country with low HD:

Part 3 – Lorenz Curve and Gini coefficient:

  • The Lorenz curve is a graphical representation of the income distribution of a country. It plots the percentage of a nation’s total income (GDP) against its total population. The “line of absolute equality” is the 45 degree line, indicating a nation where each quintile (20% of the population) earns exactly the same income as each other quintile. No country is absolutely equal, therefore the line of equality is only used for comparison.
  • The Gini coefficient is the ratio of the area below the line of equality and above a country’s Lorenz curve and the total area of the triangle below the line of equality. A country with perfect income equality would have a Gini coefficient of 0. A country in which the top 1% had controlled all of a nation’s income would have a Gini coefficient of nearly 1.

Example: Australia’s income is distributed across its population in the following way:

  • 1st 20% – 5.9%
  • 2nd 20% – 12%
  • 3rd 20% – 17.2%
  • 4th 20% – 23.6%
  • 5th 20% – 41.3%
  • Gini coefficient = 0.352

Illustrating your countries’ Lorenz Curves: This is another activity that may require research beyond the websites provided above. Try to find data on the share of national income earned by various levels of society. If you cannot find data for the 20% ranges, use the percentage ranges you can find. Draw a Lorenz curve for the two countries you researched.

Part 4 – Conclusions:

Evaluate your findings from the two countries you researched.

  1. What conclusions can you draw about the correlation between GDP, HDI, income equality, social and economic indicators between developed and developing countries?
  2. Does a high HDI correlate with relative income equality? What about low HDI?
  3. Is a high GDP indicative of high levels of human development?
  4. What other conclusions can you draw about economic development, national income, and equality?

To what extent did your country with low HD exhibit the following characteristics?

  1. Low standards of living?
  2. Low incomes?
  3. Inequality?
  4. Poor health?
  5. Inadequate education?
  6. Low levels of productivity?
  7. High rates of population growth and dependency burdens?
  8. High levels of unemployment?
  9. Dependence on agricultural production and primary product exports?
  10. Imperfect markets?
  11. Dependency on foreign developed countries for trade, access to technology, foreign investment and aid?

Surprise! Product prices have been falling for decades!

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?

Tax progressivity in the US: Do the rich pay more than their fair share? The evidence indicates NO!

From today’s New York Times:

Just How Progressive Is the Tax System? – Economix Blog – NYTimes.com

Not as much as you might think. So says Citizens for Tax Justice, which today released an updated analysis of the effective tax rates for Americans at different income levels.

Data released last week by the Congressional Budget Office underscored the progressive nature of the federal tax system. And in an op-ed article today in The Wall Street Journal, Ari Fleischer, who served as President George W. Bush’s press secretary, used that data — in particular, the income tax numbers — to argue that the wealthiest Americans bear an unfair share of the tax burden. Other research has found that many states and local governments have more regressive tax systems, though, that might offset the progressiveness of federal tax rates.

The research from Citizens for Tax Justice — a liberal organization that advocates “fair taxes for middle and low-income families” — uses 2008 data for all federal, state and local taxes combined. It found that the average effective tax rate is 29.8 percent, and that including state and local taxes makes the tax curve look much less steep:

INSERT DESCRIPTION
Horizontal axis shows the income group. Vertical axis shows the percentage of income that the average member of that group pays in taxes. Taxes include all federal, state and local taxes (personal and corporate income, payroll, property, sales, excise, estate, etc.). Incomes include cash income, employer-paid FICA taxes and corporate profits net of taxable dividends.

The group also finds that in 2008 the share of total federal, state and local taxes paid by each income group was relatively close to the share of income that that group brings in, at least as compared to comparable 2006 numbers for effective federal tax rates:

INSERT DESCRIPTION
Horizontal axis shows the income group. Taxes include all federal, state and local taxes (personal and corporate income, payroll, property, sales, excise, estate, etc.). Incomes include cash income, employer-paid FICA taxes and corporate profits net of taxable dividends.

Discussion questions:

  1. Based on the data above, do the rich in America pay an unfair proportion of the total taxes the US government collects? Why or why not?
  2. Why do the richest 5% in America actually pay a lower level of tax on average than the 5% below them?
  3. How much of America’s total income is earned by the richest 1% compared to the poorest 20%? Does America’s progressive tax system destroy the incentive for Americans to work hard and become rich? Why or why not?
  4. Does the gap between the richest and the poorest Americans surprise you? Do you think that America’s tax system is effective at re-distributing the nation’s income? How does it succeed? How could it do better?

GDP made simple…

At the end of this week, the U.S. Government’s Commerce Department will provide its first estimate of the country’s 3rd quarter (July-September 2008) gross domestic product or GDP. This upcoming GDP report is of particular interest to the world since it will provide an important measurement of how much the U.S. economy has slowed or even recessed over the last several months. Many economists predict that the upcoming GDP report will show either no significant economic growth or, very likely, negative growth.

Let me try and make the concept of GDP easy to understand and explain why it is considered 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, are produced in some other country and are a part of that country’s GDP.

If you think about it, ultimately our economic satisfaction is better measured by the goods and services that are produced and that we have access to more so than in any other single measurement, which is why GDP is the measurement that is synonymous with “economic growth”. 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.

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 second quarter 2008 U.S. GDP report highlighted a 2.8% GDP annualized growth rate. This means that the second quarter final value of goods and services produced was approximately .7% higher than the first quarter final value of goods and services produced. Thus, the quarter over quarter growth of approximately .7% was reported at an official 2.8% annual growth rate for the second quarter.

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 2008 we can say that incomes for Americans grew by 2.8% restated for inflation. 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, the landlord 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 GDP = Income and we review how the Government calculates GDP both in terms of the final market value of the goods and services as well as how that same production value is reconciled to the incomes of others.

I find the preceding paragraph, GDP = Income, to be a break through moment for a lot of citizens in truly understanding the GDP measurement. It is easier for most citizens to think in terms of income percentage growth in lieu of GDP growth. Most citizens are surprised to find that incomes or GDP, restated for inflation, have increased by 17.4% from 2000 – 2007. This 8-year growth rate in GDP or incomes still equates to a below average historical average performance. More specifically, over the last 8 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.

How Much Does One Need to be Rich?

CHICAGO, January 7, 2008 – How much money does it take to be considered rich?  It turns out that $1 million just doesn’t cut it, anymore.

In fact, rich today requires at least $5 million, according to a new survey of affluent households, defined as those with investable assets of $500,000 or more.  When asked how much money it takes to be rich, 45% chose $5 million, 25% selected $25 million, and 8% picked $100 million, according to the research by Millionaire Corner (http://www.millionairecorner.com/index.php), a newly launched website powered by Spectrem Group.  Only 22% said $1 million is enough to be rich.

 Achieving such wealth – and holding onto it for generations – is the topic of a new book by Spectrem’s Catherine S. McBreen and George H. Walper, Jr. titled Get Rich, Stay Rich, Pass It On: The Wealth Accumulation Secrets of America’s Richest Families” (http://getrichstayrich.net/).  Published this month by Portfolio and available in bookstores now, the book is based on years of research in addition to interviews with ordinary individuals who were able to amass enough wealth to pass on to future generations. “All you really need is to know how to use the same wealth-building tools Carnegie and du Pont and all the other progenitors of sustainable fortunes used,” McBreen and Walper write.  “They created the model but they didn’t patent it.  It’s available for your use, and this book is the operating manual.” 

The authors found that the proper mix of entrepreneurial activities and income-producing real estate is the key to achieving building perpetual wealth. Get Rich, Stay Rich, Pass It On” walks readers through not only the theory but the practice of building sustainable fortunes.  It not only lays out the model, but provides exercises to help readers bring their own finances into focus and determine what they need to do to develop perpetual wealth of their own.

 

* * *

 The data on how much it takes to be rich are based on 253 telephone interviews conducted in December 2007, with a margin of error of plus or minus 6.2 percentage points.  Interviews were conducted with the financial decision-makers in households with $500,000 or more in investable assets.

Is Switzerland becoming a feudal state?

Switzerland “could become a feudal state” claims an economist. – swissinfo

One Zurich economist thinks so:

In Switzerland 71 per cent of the wealth is concentrated in the hands of just ten per cent of the population – a figure that economist Hans Kissling finds alarming.

Kissling tells swissinfo that the gap between the rich and everyone else is growing and that this could threaten traditional Swiss democracy and the economy. He makes a call for an inheritance tax for the wealthy.

Statistics show that the 300 richest people have become 40 per cent wealthier in the past eight years, whereas most of the population has a lower income than at the beginning of the 1990s

Kissling has nothing against wealth, he just thinks that if someone did not earn their wealth but inherited it instead, they should have to share a bit with the rest of society.

I call for a tax on very high inheritances, from SFr1 million ($900.000) upwards, and only on the excess value of that. I certainly don’t want people to think that they can’t pass on their family home to the next generation.

I’m only interested in trying to stop any creeping feudalisation, to avoid having huge clans like in South America, which threaten the economy and the political world

He’s most concerned that if the gap between rich and middle class continues to widen and the middle class of Switzerland don’t start benefiting from the country’s growing wealth, there could be a dangerous backlash against the free market system.

…the richest one tenth of a percent in Zurich – there are no full Swiss statistics – had 677 times more wealth than an average citizen in 1991. By 2003, 12 years later, the richest one tenth of a percent had 1,027 times more wealth. So the gap has really grown.

The middle classes, unlike the lower classes, have not benefited from any concessions, such as health insurance or childcare allowances. Here they have to use up all their assets before they receive any support. The lower classes have help from the beginning. This is why the middle classes are threatened

Discussion Questions:

  1. Why does a growing gap between rich and middle class threaten social stability in Switzerland?
  2. What would advocates of socialism propose in order to avoid future struggles between the rich and the middle class?
  3. What kind of tax system would help re-distribute the wealth of Switzerland and narrow the enormous gap that exists here?
