How do we rank countries?

Economic Growth and Happy Electorate

Economic growth did not necessarily translate into a happy electorate.  

  • Political leaders around the world in the late 2010s were stunned to see that economic growth did not necessarily translate into a happy electorate.  Many political leaders were seeing public approval ratings reach record lows.
  • On the other hand, many authoritarian leaders of countries with declining economies were reelected with record levels of support.


GDP and GNP

GDP is the traditional measure of the total output of goods and services per year.  Basically, GDP adds up the money we as consumers and companies and government entities spend over the course of the year.

GNP - gross national product - picks up where GDP leaves off and includes international expenditures in its summary of economic growth.  

  • Money coming from foreign sales of products or services, make GNP a broader summary of a given economy.  
  • Also included are payments and income from foreign stocks or interest payments on bonds that one country's government has sold to another.  This is an important consideration in the twenty-first century economy, where exporting nations like China and Saudi Arabia hold trillions of dollars in U.S. Treasury bonds.


GNP>GDP or  GDP>GNP

Sometimes GNP is bigger than GDP, and sometimes it is the other way around.  

  • Countries like Ireland, which has a lot of foreign-owned companies, tend to give the country smaller GNP than GDP because the payments to foreign owners are deducted from the GDP figures.  
  • On the other hand, since British, U.S. and Swiss residents tend to own a lot of companies abroad, their GNP is usually larger than their GDP because it includes income from foreign production that is not included in the domestic summary.


How do you compare GDP among countries with different currencies?  

It is difficult, because the value of economic activity in each country is denominated in currencies that are constantly changing in value.  

One method is simply take the value of each country's GDP at the end of the year and translate it into one common currency using official exchange rates.

  • Unfortunately, using official currency exchange rates gives a skewed idea of many countries economic health.  
  • Since the cost of similar goods and services isn't the same in every country, the total value of each countries' goods and services can vary widely.

Most economists and statisticians, try to adjust each country's GDP using a "real world" exchange rate.  

  • This is commonly referred to as purchasing power parity or PPP.  
  • It is an important calculation for anyone wanting to get a clear understanding of the real economic value of every country.  
  • To determine which economy is the biggest in the world, for example, you have to adjust nominal GDP figures using PPP; otherwise the figures are of little value.


PPP is a simple calculation.  

One country's currency, such as the U.S. dollar, is chosen as the base currency.  

The dollar value of a selected basket of goods and services is then compared to the value of the same items in another country using traditional exchange rates.  In most cases, the two values won't be the same.

It is often difficult to come up with a perfectly reliable PPP.  The choice of items to be included in the basket used to determine PPP has to be made carefully.


The Big Mac Index

The Economist magazine, somewhat jokingly, came up with a PPP using the costs of Big Macs around the world.  

Since the Big Mac is identical in every country, and sold all over the world, the Big Mac Index has now become a reliable tool to see how prices vary around the world.


GDP per capita

It can also be useful to relate a country's total GDP to the number of inhabitants, giving us a more realistic view of how wealthy a country really is.  

GDP per capita, is often used to compare economic power among countries.  

By dividing each country's total economic output by the number of people living in the country, we get a more accurate idea of who is richer.  


Impossible to capture the complete picture

No measure of economic growth and economic power, however, is able to capture the complete picture.  

Quality of life

Quality of life, for example, isn't included in traditional measures of GDP.  

The GNP does not allow for the health of our children, the quality of their education, or the joy of their play.  

Neither GNP nor GDP gives us a truly complete picture of our economic health.  


UNHDI measures of Economic well-being (most popular)

The most popular accepted measure of economic well-being is the United Nations Human Development Index (UNHDI), which rates countries according to their levels of health, education, and income. 

The UNHDI measures such areas as 

  • life expectancy, 
  • access to education and adult literacy, 
  • years of schooling, 
  • equitable distribution of income, 
  • GDP per person adjusted by PPP, 
  • health care and 
  • gender equality.  
Countries that pay a lot of attention to quality-of-life issues like education and health care - like Norway, Australia and Switzerland - appear high on the list.


Gross National Happiness Index

Some countries, such as Bhutan, have tried to look less at tangible measures and more at happiness, instituting a Gross National Happiness measure in 1972.  

Although happiness and well-being are notoriously difficult to measure, tracking opinion polls, search request data, and social media activity give us valuable information that can be used to determine which country can justifiably chant, "We're number one!"

Currencies trading are very difficult.

Currencies trading are very difficult. They are more difficult than stocks and certainly more difficult than interest rates.

You need to learn by looking at price behaviour in the past, but trying to understand what currencies have done even recently is tough. There have been some big moves.

Take the US dollar versus euro rate, for example. It has ranged over the last few years from around 85 to 130. How is it possible that the currencies of the world's two largest economies can change in relative value by over 50%?

These types of currency moves are intriguing.
  • The first thing to be aware of, is that you are looking at two economies. With stocks and interest rates, youj basically have only one economy to figure out.
  • However, the second and bigger challenge is that currencies are largely driven by market sentiment, and the reason is that there is absolutely no successful benchmark for the pricing of a currency.

1. Purchasing price parity (PPP) is not much use

This theory suggests that currencies should tend towards the level where a collection of goods and services costs the same amount in different countries. PPP would suggest that if they are too expensive in one country, then that country's currency should fall.

The famous McDonald's Big Mac index is sometimes published in the Economist magazine, and it applies this analysis, to the price of the burgers in various countries.

The problem is that in reality PPP does not seem to have much impact on currency level. Perhaps it is for the same reason that people living in tiny but very expensive apartments in Tokyo do not migrate to Sydney or LA and buy a huge house. If they did, perhaps currencies would be easier to evaluate.


2. Market sentiment has the most impact

Since there are no reliable benchmarks, market sentiment is the huge factor that dominates events.

In 2005, the US dollar has been out of favour, despite an improving US economy and rising US dollar interest rates. The market is more worried about the US current account deficit. But is that econmies or fashion? There's the difficulty.


Conclusion

You need not avoid currency trading completely.

There are occasional opportunities such as the big market moves that you have seen in the major currencies during the last few years.

You should only be involved when you have a very firm grip on what's driving the market. That doesn't happen too often for any of us!
