AmosWEB means Economics with a Touch of Whimsy!

INCOME-EXPENDITURE MODEL: A macroeconomic model, which captures the essence of Keynesian economics, is based on the equality between total income generated from gross domestic product and total expenditures on gross domestic product. The cornerstone of the income-expenditure model is the consumption function, which relates household consumption expenditures to income and gives rise to the aggregate expenditure line with the addition of investment, government purchases, and net exports. The intersection between the aggregate expenditure line at the 45-degree identifies equilibrium.

SPECIALIZATION:

The condition in which resources are primarily devoted to specific production tasks. This is one of THE most important and most fundamental notions in the study of economics. Civilized human beings have long recognized that limited resources can be more effectively used in the production of the goods and services that satisfy unlimited wants and needs if those resources specialize.
Specialization is closely related to the concept of labor',500,400)">division of labor. To the extent that specific production tasks are divided among different workers, each worker is able to specialize. If every worker performs every task, then specialization is not possible.

Hot Fudge Sundaes

Suppose, for example, that three workers are involved in the production of hot fudge sundaes. Total hot fudge sundae production can be greater through specialization. One worker retrieves the dish, another scoops the ice cream, and a third adds the hot fudge topping. By devoting their energies to learning how to do their respective tasks really, really well, these three workers can produce more hot fudge sundaes than if each performed all required tasks.

More than Labor

Examples of labor specialization are prevalent throughout the economy. However, specialization works for all resources--labor, capital, land, and entrepreneurship.
  • Consider the case of capital. Different tools, machinery, equipment, buildings, factories, and other structures are typically designed for specific purposes. A hammer, for example, is well-suited for driving nails into wood, but it is not well-suited for removing spark plugs from automobile engines. A socket wrench works much better. Special tools work best for specific tasks.

  • Land also tends to be more productive when it specializes. Flat land, in a temperate climate, with abundant sunshine, and periodic rainfall works quite well in agricultural production. However, if it does not contain petroleum reserves or mineral deposits, it does not function well in the mining industry. By contrast, a steep mountain slope atop a rich supply of copper ore is a productive input in the mining industry, but is not well-suited for agricultural production.

Seeking Specialization

When resources, especially labor, specialize in particular production tasks, they tend to become more productive. This can be achieved either naturally or through modification, especially the education and training of workers.
  • Harold "Hair Doo" Dueterman, for example, is a naturally talented and gifted athlete, who specializes in playing center field for the Shady Valley Primadonnas baseball team. He has the natural speed, agility, strength, and hand-eye coordination needed to hit a baseball approaching him at ninety miles an hour. However, his specialization has been enhanced by years of practice and training.

  • The medical building used by Dr. Dowrimple T. Bedside was originally (that is, naturally) constructed for use as medical offices. However, over the years, Dr. Bedside has remodeled his offices to function even more effectively in the provision of medical care.

[What's This?]

Today, you are likely to spend a great deal of time at a going out of business sale wanting to buy either blue cotton balls or a genuine down-filled pillow. Be on the lookout for crowded shopping malls.
Your Complete Scope

This isn't me! What am I?

More money is spent on gardening than on any other hobby.
"You have to find something that you love enough to be able to take risks, jump over the hurdles and break through the brick walls that are always going to be placed in front of you. If you don't have that kind of feeling for what it is you're doing, you'll stop at the first giant hurdle. "

-- George Lucas
