Answer:
The correct answer is option a.
Explanation:
The full-employment level of output is $2,000.
The current level of output is $1,900.
The current aggregate demand is $1,850.
There is a need to increase the aggregate demand by $150 to reach full employment level.
The government increases purchasing by $30.
1 - MPC = 
MPC = 1 - 0.2
MPC = 0.8
Answer:
42 days.
Explanation
Note: The full question is attached as picture below
Account receivable turnover ratio = $612,000 / $70,422
Account receivable turnover ratio = 8.69
Account collection period = 365 / 8.69
Account collection period = 42.00230.
Thus, the firm’s sales uncollected for year is 42 days.
There are three ways to cope up with the problem of scarcity:
a. Economic growth.
b. Improvement of use of available resources.
c. Reduction of wants.
Explanation: Economic growth mean the ability if an economy to produces products and services. Using the products wisely can improve the usage and helps in saving the resources. Society can improve the use their existing or available resources in order to reduce the scarcity by: Efficiency in productivity, efficient allocation of resources, full employment with minimum wastage and equity.
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.
