The economist Adam Smith defines capital as, "that part of man's stock which he expects to afford him revenue. Ever-improving capital is important because of what follows its production: cheaper and more bounteous goods.
Note that money is not included among the factors of production. While money facilitates trade and is an effective measure of a good's value, individuals cannot eat, wear, or be sheltered by money itself. The ultimate aim of economic activity, work, and trade is to acquire goods, not money. Money is a means to afford goods. Better capital goods allow people to travel farther, communicate faster, eat better foods, and save enough time from labor to enjoy leisure.
Many countries have printed and inflated their way into poverty by losing focus on savings, investment, and capital equipment in favor of increasing their money supply by printing more of their currency. Before a factory can be built or a car can be manufactured, someone must have saved enough resources to be able to survive the production process.
This involves forgoing present consumption in favor of greater future consumption. Every capital production process starts with savings. Savings help by generating investments. Investments eventually lead to finished goods and services. Traditionally, it is the role of the capitalist to first save and then assume risk by employing people in production processes before revenue is generated from the finished goods.
All of the factors of production interact with one another. Natural resources are transformed into capital goods by human labor and subjected to market risk through entrepreneurial activity.
Each factor of production is able to contribute to production processes and earn an income based on its use. The income for land is usually called rent. Labor receives wages. Employed capital goods and equipment receive interest, normally through their investment.
Successful entrepreneurs receive profits. Business Essentials. Actively scan device characteristics for identification.

For example, one factor that may have affected Australia is its isolation from Europe, which may have insulated the country from the effects of the global recession.
Even small changes in the rate of growth, when sustained and compounded over long periods of time, make an enormous difference in the standard of living. Consider Table 3 , in which the rows of the table show several different rates of growth in GDP per capita and the columns show different periods of time.
Assume for simplicity that an economy starts with a GDP per capita of The table then applies the following formula to calculate what GDP will be at the given growth rate in the future:. Table 3 shows that even a few percentage points of difference in economic growth rates will have a profound effect if sustained and compounded over time.
Rapid rates of economic growth can bring profound transformation. See the following Clear It Up feature on the relationship between compound growth rates and compound interest rates. The formula for growth rates of GDP over different periods of time, as shown in Figure 2 , is exactly the same as the formula for how a given amount of financial savings grows at a certain interest rate over time, as presented in Choice in a World of Scarcity. Both formulas have the same ingredients:.
Recall that compound interest is interest that is earned on past interest. It causes the total amount of financial savings to grow dramatically over time. Similarly, compound rates of economic growth, or the compound growth rate , means that the rate of growth is being multiplied by a base that includes past GDP growth, with dramatic effects over time. Productivity, the value of what is produced per worker, or per hour worked, can be measured as the level of GDP per worker or GDP per hour.
The United States experienced a productivity slowdown between and Since then, U. It is not clear whether the current growth in productivity will be sustained.
Over decades and generations, seemingly small differences of a few percentage points in the annual rate of economic growth make an enormous difference in GDP per capita. An aggregate production function specifies how certain inputs in the economy, like human capital, physical capital, and technology, lead to the output measured as GDP per capita.
Compound interest and compound growth rates behave in the same way as productivity rates. Seemingly small changes in percentage points can have big impacts on income over time.
Skip to content Chapter Economic Growth. Learning Objectives By the end of this section, you will be able to:. How are compound growth rates and compound interest rates related? Both formulas have the same ingredients: an original starting amount, in one case GDP and in the other case an amount of financial saving; a percentage increase over time, in one case the growth rate of GDP and in the other case an interest rate; and an amount of time over which this effect happens.
Self-Check Questions Are there other ways in which we can measure productivity besides the amount produced per hour of work? Assume there are two countries: South Korea and the United States. What will the incomes of the United States and South Korea be in 20 years?
How do gains in labor productivity lead to gains in GDP per capita? Critical Thinking Questions Labor Productivity and Economic Growth outlined the logic of how increased productivity is associated with increased wages. Detail a situation where this is not the case and explain why it is not.
Change in labor productivity is one of the most watched international statistics of growth. This is a value-added process that can effectively raise living standards through decreasing the required monetary investment in everyday necessities and luxuries , making consumers wealthier in a relative sense and businesses more profitable.
From a broader perspective, increased productivity increases the power of an economy through driving economic growth and satisfying more human needs with the same resources. Increased gross domestic product GDP and overall economic outputs will drive economic growth, improving the economy and the participants within the economy. As a result, economies will benefit from a deeper pool of tax revenue to draw on in generating necessary social services such as health care, education, welfare, public transportation and funding for critical research.
The benefits of increasing productivity are extremely far-reaching, benefiting participants within the system alongside the system itself.
To expand upon this, there are three useful perspectives in which to frame the value in improving productivity within a system from an economic standpoint:. The final important consideration in assessing productivity potential is the production-possibility frontier PPF , which essentially outlines the maximum production quantity of two goods in the scope of our current technological capacity and supply. This demonstrates the confinement of productivity, and thus is well captured in the Leontief production function.
The critical takeaway here is that the production function will generally be affected by two things: overall supply and technological capabilities. Note that demand does not come into account in altering the production function or overall productivity potential.
The illustration in the following figure demonstrates an increase in PPF, thus affecting the production function. Production-Possibility Frontier Expansion : In this graph, the prospective production-possibility frontier shifts to the right, implying a higher supply or improved technological production ability of the two goods being discussed in this case guns and butter.
Productivity is represented by production functions, and is the amount of output that can be generated from a set of inputs. Productivity, in economic terms, measures inputs and outputs to derive overall production efficiency within a system.
Simply put, it measures how much can you get out of what you put into a given system. Increased productivity means more output is produced from the same amount of inputs. In order to generate meaningful information about the productivity of a given system, production functions are used to measure it. Understanding the way in which productivity metrics function, one can more comprehensively grasp the concept and employ it in a meaningful way. From an economic standpoint, the production function demonstrates the tangible output created as a result of a production process including all tangible inputs.
The objective in employing this perspective is to pursue allocative efficiency within the process as opposed to technical or logistical efficiency, as engineers or supply chain managers may be pursuing.
This means that the production function identifies optimal inputs and consequent outputs to satisfy the needs of a given population via a particular production process. While different economic perspectives often identify different factors of production i.
Conceptually, the production function makes certain assumptions of the maximum potential production, availability of inputs and demand for outputs to create a boundary of potential production. This will include the derivation of a marginal product for each factor see , or essentially the extra output that can be created for each additional unit of input.
Naturally, this is theoretically subjected to the concept of diminishing marginal returns, where the marginal product of a given input in the figure we are illustrating labor will fall as the starting points for quantity rise.
