Factors of production, at Answers.com
Classical economics distinguishes between three factors:
- Land or natural resource—naturally-occurring goods such as soil and minerals that are used in the creation of products. The payment for land is rent.
- Labor—human effort used in production which also includes technical and marketing expertise. The payment for labor is a wage.
- Capital goods—human-made goods (or means of production) which are used in the production of other goods. These include machinery, tools and buildings. In a general sense, the payment for capital is called interest....

Lower birthrates and longer life lead to "population aging" (i.e., more elderly people and fewer children). Population aging is most rapid, and has gone farthest, in the developed world....

Natural Resources, from the Concise Encyclopedia of Economics
The earth's natural resources are finite, which means that if we use them continuously, we will eventually exhaust them. This basic observation is undeniable. But another way of looking at the issue is far more relevant for assessing social welfare. Our exhaustible and unreproducible natural resources, if measured in terms of their prospective contribution to human welfare, can actually increase year after year, perhaps never coming anywhere near exhaustion. How can this be? The answer lies in the fact that the effective stocks of natural resources are continually expanded by the same technological developments that have fueled the extraordinary growth in living standards since the industrial revolution....
Human Capital, from the Concise Encyclopedia of Economics
To most people capital means a bank account, a hundred shares of IBM stock, assembly lines, or steel plants in the Chicago area. These are all forms of capital in the sense that they are assets that yield income and other useful outputs over long periods of time.
But these tangible forms of capital are not the only ones. Schooling, a computer training course, expenditures of medical care, and lectures on the virtues of punctuality and honesty also are capital. That is because they raise earnings, improve health, or add to a person's good habits over much of his lifetime. Therefore, economists regard expenditures on education, training, medical care, and so on as investments in human capital....

Gender Gap, from the Concise Encyclopedia of Economics
When economists speak of the "gender gap," these days they usually are referring to systematic differences in the outcomes that men and women achieve in the labor market. These differences come in the percentages of men and women in the labor force, the types of occupations they choose, and the difference in the average incomes of men and women. These economic gender gaps have been a major issue in the women's movement and a major issue for economists....

A Little History: Primary Sources and References
Capital and Interest A Critical History of Economical Theory, by Eugen von Böhm-Bawerk
It is generally possible for any one who owns capital to obtain from it a permanent net income, called Interest.
This income is distinguished by certain notable characteristics. It owes its existence to no personal activity of the capitalist, and flows in to him even where he has not moved a finger in its making. Consequently it seems in a peculiar sense to spring from capital, or, to use a very old metaphor, to be begotten of it. It may be obtained from any capital, no matter what be the kind of goods of which the capital consists: from goods that are barren as well as from those that are naturally fruitful; from perishable as well as from durable goods; from goods that can be replaced and from goods that cannot be replaced; from money as well as from commodities. And, finally, it flows in to the capitalist without ever exhausting the capital from which it comes, and therefore without any necessary limit to its continuance. It is, if one may use such an expression about mundane things, capable of an everlasting life....

Frank Knight, biography from the Concise Encyclopedia of Economics
Knight's final contribution was his work on capital theory in the thirties. Knight criticized Böhm-Bawerk's view that capital could be measured as a period of production (see Böhm-Bawerk). Knight was seen to have won the debate over the Austrian concept of capital.
The Positive Theory of Capital, by Eugen von Böhm-Bawerk
There is scarcely a system or a text-book of Political Economy which does not, at some point or other, bring in discussions of matters belonging to the physical sciences. Usually these are introduced in the chapter on Production. There we are taught that to create new goods does not mean to create new material, since matter is constant and cannot be increased. We learn what nature contributes to the work of production in the shape of materials and powers; what is done by the mechanical, what by the chemical, and what by the organic powers of nature; what importance climate, heat, moisture have on the development of production; on what physical and technical foundations the working of machinery rests; and many things of this sort....
