The central problem of economics is to satisfy the people's and nation's 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 country's 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 government's 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.
