Economists like to use the Gross Domestic Product (GDP) as an indicator for how well a country is doing. In order to make predictions regarding the future of countries and the industries that support the country it is essential to be able to evaluate just what makes the GDP vary so dramatically over time and across countries.

Over the past 130 years the output of countries has dramatically improved in a good portion of the world. Some countries have improved much better than others. Many studies have been done to determine what the factors are that influence the growth of the GDP. We will briefly touch on the major factors that have the most influence and then explain in a little more detail the important factors that have helped stable, mature industrial economies sustain long-term growth. After that we will discuss why the majority of these factors will not sustain continued growth in established economies and finally we will offer a solution for providing real sustained growth over the long term.

THE BUSINESS CYCLE

All businesses and economies, just like a stock market, have trends. There are also fluctuations to these trends over short term. These fluctuations above and below the output trend are known as business cycles. It is believed that over short-term analysis business cycles do affect output, however when one looks at the long-term, these cycles, or deviations from the trend (average), tend not to be as influential in the level of output as we would think. The long-term output tends to be the average of the peaks and troughs of the cycles of business.

FACTORS THAT GO INTO THE GDP (OUTPUT)

The GDP per capita is a function of the (hourly productivity) x (the average hours worked per person) x (the employment rate) x (the participation rate).

Hourly Productivity is dependent on many different factors: the physical infrastructure in which the worker works (buildings and machinery); education, skills, technology level and efficiency of the worker and more.

We could further subdivide this "hourly productivity" into two more categories:

Physical Capital Stock (buildings and machinery), and "Other" (education, skills, technology level and efficiency, etc.).

In economics terms, this "other" is known as Total Factor Productivity (TFP).

Now if we look at the equation, we can see that GDP (output) is affected by Physical Capital, Labour, and TFP.

GDP = Capital x Labour x TFP.

DECREASING MARGINAL PRODUCT CAPITAL (DPK)

Decreasing marginal product capital (DPK) tells us that as each new machine is added to the system; it boosts productivity less than the previous machine until at one point the last machine added offers no boost in productivity. This line is the point of equilibrium for productivity beyond which we no longer have positive results. As long as the net investment is positive a company will continue to invest, but as soon as it crosses over the line of positive output growth, they will no longer invest.

PHYSICAL CAPITAL EQUILIBRIUM STATE

We can accumulate physical capital and thereby allow the worker to work more efficiently. Capital includes machinery and buildings in which to work. Usually there is a depreciation factor in these physical products therefore over time, their value works toward equilibrium, such that the input of capital equals exactly the same value as the depreciation. It is at this steady state point that capital ceases to provide increased growth output. All companies and industries eventually move toward this steady state position. If all companies achieve this steady state, as shown in Figure 4.12 on page 71 of our text, they will converge to the same posit
