Small economy I think or up close economy
Answer:
c. It depends on the appraisal problem. The appraiser should apply all appropriate units of comparison, explain differences in wide variation in the results, and choose the most reliable unit.
Explanation:
The three (3) main methods used for the valuation or appraisal of real-estate properties are;
I. Income approach.
II. Cost approach.
III. Sales comparison approach.
A sales comparison approach can be defined as a real-estate appraisal technique that is typically based on comparing a property to other recently sold real-estate properties with similar characteristics. Thus, this appraisal method or technique requires that the real-estate property being appraised should be in current use and fall within the same area or locality as the other recently sold real-estate properties.
In the sales comparison approach, the appraised property should mimic the market behavior of other real-estate properties sold recently.
Answer:
C. A country can specialize in producing that for which it has a comparative advantage and then trade for other needed goods and services.
Explanation:
<em>Comparative advantage</em> is simply evaluating the opportunity cost of other benefits or costs, if the country is opting to choose for a specific category of goods for production purposes.
For example, let's say US can produce 20 Television (TV) sets and 50 Air Conditioners in a month. Here, the opportunity cost of producing 1 TV set is 50/20 i.e. 2.5 Air Conditioners. Similarly, the opportunity cost of producing 1 Air Conditioner (AC) is 20/50 i.e. 0.4 TV set. Hence, US should produce Air Conditioners over TV sets as per <em>Comparative Advantage</em> concept.
Take another example, let's say UK can produce 50 Television (TV) sets and 20 Air Conditioners in a month. Hence, the opportunity cost of producing 1 TV set is 20/50 i.e. 0.4 Air Conditioner. On the other hand, the opportunity cost of producing 1 AC is 50/20 i.e. 2.5 TV sets. Thus, UK should produce TV sets over AC's as per <em>Comparative Advantage </em>model.
Hence, US should export AC's to UK and import TV sets from UK to gain from specialization and trade.
<em> In this way nations can gain from specialization and trade by making use of Comparative Advantage theory</em>.
It is to be noted that <em>Absolute Advantage model </em>of Adam Smith is also good as it highlights production of that good by a country, which it can produce in large quantities with fewer resources and minimal time than any other nation in the world. But the <em>Comparative Advantage Model </em>developed by David Ricardo considers opportunity cost and is much more refined than Absolute Advantage Model.
