The central problem of economics is to satisfy the peoples and nations wants.
The problem we are faced with is that our resources, here identified as money, are __1__. The only way we can resolve our problem is to make choices. After looking at our resources, we must examine our list of __2__ and identify the things we need immediately, those we can postpone, and __3__ we cannot afford. As individuals, we face the central problem involved in economics-deciding just how to allocate our limited our limited resources to provide __4__ with the greatest satisfaction of our wants.
Nations face the same problem. As a countrys population ___5__, the need for more goods and services grows correspondingly. Resources necessary to production may increase, but there __6__ are enough resources to satisfy the total desires of a nation. Whether the budget meeting is taking place in the family living room, in the conference room of the corporation __7__ of directors, or in the chamber of the House of Representatives in Washington, the basic problem still exists. We need to find __8__ of allocating limited resources in order to satisfy unlimited wants.
A short time ago economists divided goods into two categories, free and economic. The former, like air and water, were in __9__ abundance that economists had no concern for them. After all, economics is the __10__ of scarcity and what to do about it. Today many of these free goods are __11__ very expensive to use. Pollution has made clean air and water expensive for producers extra costs, and __12__ taxpayers who pay for the governments involvement in cleaning the environment.
In the 1990s, almost all goods are __13__. Only by effort and money __14__ obtained in the form people wish.
Meeting needs of people and the demands from resource available __15__ the basic activity of production. In trying to meet unlimited wants from limited economic goods, production leads to new problems in economics.
