Chapter 1, Problem 1QFT
To determine
Illustration of twelve principles of economics in each of the given cases.
Concept Introduction:
Principles of Individual Choice:
- “Choice is necessary because resources are scarce”- Resources are always scarce in respect to its use, a single resource can be put to various alternative uses. Therefore, one has to choose between the various uses.
- “The true cost of something is its
opportunity cost ”- The value of any commodity is derived from the forgone cost to get that particular commodity. - “How much is the decision at the margin”- The choice of having something depends on the benefits one receive from that choice.
- “People usually exploit opportunities to make them better off”- People are always fond of alternative incentive, which can make them in better situation as compared to the previous situation.
- “
Gains from trade ”- Individual always gain from trade by selling the product in which they are specialized and purchasing the product in which they are comparatively less specialized. - “Market moves towards equilibrium”- Market always tries to settle down at a point where no individual is comparatively better off in changing his choice.
- “Resources should be used efficiently to achieve society’s goals”- Resources should be used in such a way that will not make any better off by making the other individual worse off.
- “Markets usually lead to efficiency”- People always look for the opportunity, which can make them better off without making any other person worse off, this leads to
efficiency in the market. - “When markets don’t achieve efficiency, government intervention can improve society’s welfare”- Government intervention is required when the market do not correct itself.
- “One person’s spending is another person’s income”- The economy will always go a person earns on because only when the other person spends.
- “Overall spending sometimes gets out of line with the economy’s productive capacity”- The economy can face inflation at the time when spending of whole economy raises all together.
- “Government policies can change spending”- Various fiscal and
monetary policies of government are used to correct the situation of the economy and adjust the spending.
Expert Solution & Answer

Explanation of Solution
- The empty seats of plane and empty beds of hotel were analyzed and alternate action was taken to earn revenue from these seats, therefore in this case the principle used is“The true cost of something is its opportunity cost”.
- Some passengers like to book their seats in advance whereas some like to wait for the last minute;therefore, in this case the principle used is “How much is the decision at the margin”.
- A way found by price line to make everyone better off, including itself;therefore, in this case the principle used is“People usually exploit opportunities to make them better off”.
- The spending of travelers is the earnings for hotel owners;therefore, in this case the principle used is “One person’s spending is another person’s income”.

The graph shows the supply and demand curves of high-fructose corn syrup, a sweetener commonly used in the production of
sweets and soda due to its low cost. In an effort to curb health issues, Congress puts an excise or commodity tax on corn syrup
at $2 per liter.

- 1. A town relies on four different sources for its non-drinking water needs: dam water, reclaimed water, rain water, and desalinated water. The different sources carry different risks and costs. For instance, desalinated water is fully reliable due to abundant sea water, but it is more expensive than other options. Reclaimed water also has relatively lower risk than rain or dam water since a certain amount can be obtained, even during the dry. season, by the treatment of daily generated waste water. Using any of the four options requires an investment in that resource. The return on a particular water source is defined as the amount of water generated by the source per dollar of investment in it. The expected returns and standard deviations of those returns for the four water sources are described in the following table: Water resource Expected return St. Deviation Dam water 2.7481 0.2732 Reclaimed water 1.6005 0.0330 Rain water 0.5477 0.2865 Desalinated water 0.3277 0.0000 Higher…arrow_forward1.

Using the concept of opportunity cost, explain why it most likely has a bowed-out shape. b. Show a point that is impossible for the economy to achieve. Show a point that is feasible but inefficient. c. Imagine that the society has two political parties, called the Hawks (who want a strong military) and the Doves (who want a smaller military). Show a point on your production possibilities frontier that the Hawks might choose and a point the Doves might choose. d.
