When Paul Samuelson switched from physics to economics, Robert Solow is said to have remarked that the average IQ in
both disciplines went up. A bystander responded that Solow's claim must be wrong because it implies that the average IQ
for academia as a whole (which is a weighted average of the average IQ levels for each discipline) must also have gone
up as a result of the switch, which is clearly impossible.
Was the bystander right?
A) Yes. If the average in both disciplines goes up then the population average must also rise.
B) No. There is not enough information about the average IQ for the population.
C) Yes. The weights may change so that the population average also increases.
D) No. If those in physics had IQs above average and those in economics has IQs below average, then the population
average need not have changed.
The production possibilities frontier (PPF) is a simplified economic model that illustrates the different combinations of two products that an economy can produce given the resources it has available. Assume the country of Turkey can produce only apples or oranges and answer each of the following questions
A if a flood destroyed 20% of the farmland used to grow apples and oranges, which direction will Turkey's PPF shift /your answer should be "outwards" or "inwards") and why?
B. Turkey decides to begin increasing, the production of oranges. Explain the implications of this using the term "opportunity cost"
C An advancement in organic pesticide has allowed for less fruit to be damaged by pests. Explain how this change would alter the PPF.
Introduction to the Production Possibilities Curve (PPC)
As you know, the basic economic problem is scarcity. Since we do not have enough scarce resources to satisfy
everyone's needs and wants, we all have to make choices. We must choose how to spend our time, our energy, our
money, and our material possessions, and for every choice that is made, a cost is suffered.
The relationship between choice and cost can be shown in a graph called a production possibilities curve, or PPC. For
example, consider a student who has 4 hours of free time in the evening. He or she can choose to spend some, all, or
none of those 4 hours studying for a test the following day. He or she could also use the time to catch up on sleep.
These choices can be graphed:
Choice A - spend all 4 hours studying
Choice B- spend 2 hours studying, and 2 hours getting extra sleep
Choice C- spend all 4 hours sleeping
Of course, other combinations of the 4 hours exist.
The student could study for 3.5 hours, and get an extra…

- Which of the below statements DOES NOT capture Economics? Group of answer choices Economics tells us that there is no theoretical limit to how well we can live or how widely our wealth can spread. The economic prosperity of an economy requires that every person in that economy have a Ph.D. degree. Wheelan argues that the free market system does not make poverty inevitable. Economic development is not a zero-sum game. Even the most prosperous economy will contiue to require certain manual tasks that do not require advanced college degrees. These tasks cannot be replaced with automation. Expecting Ph.D.s or people with professional education to do such tasks will have a high opportunity cost.arrow_forwardLike a good economist, you calculated the cost of getting your college degree, including the opportunity cost. Suppose that at your university, you will pay $15,000 each year for tuition, $3,000 each year for textbooks, and $8,000 per year for room and board. Before you left for college, your boss at your high-school job offered you a job paying $15,000 per year.Assume that if you decided not to go to college, your parents would let you live at home for free.Including the opportunity cost, what is the cost of attending four years of college? $arrow_forwardLike a good economist, you calculated the cost of getting your college degree, including the opportunity cost.

- "Vernon Smith started a series of experiments to see whether basic predictions of the standard economic model about markets would prove correct. [...] Basically, the predictions proved good. A stunning result! Maybe, therefore, it doesn't matter if people are not like homo oeconomicus; the standard economic model can still work." (quote shortened, source: Edward Cartwright in his textbook "Behavioral Economics" (3rd edition, p. 8)). What kind of criticism of the standard economics model does Cartwright refer to? Explain why Vernon's findings can be used to support and uphold the standard model of microeconomics despite unrealistic assumptions?arrow_forwardAssume there are only two goods in the world: pizza and electric fans. Draw a production possibility frontier (PPF) illustrating the trade-off between the two (specific numbers are not needed – we are only looking for the basic shape of the PPF). On the same graph, draw new frontiers showing 1) what happens if a major plague reduced worldwide population significantly, and 2) if a machine is invented which doubles the number of fans that can be made in a day (but is irrelevant in the production of pizza).arrow_forwardLocal government bans on plastic grocery bags due to environmental concerns have led to increased emergency room visits and deaths related to harmful bacteria such as E. coli, as many people do not wash their bags after each use. Which of the following best characterizes the statement? The statement demonstrates that even when government policies are enacted with good intentions, they do not always guarantee good outcomes due to unintended consequences and secondary effects. The statement demonstrates that normative economics is often confused with positive economics. The statement is an example of the fallacy of composition because all foods do not contain harmful bacteria. The statement shows that all environmental regulations have benefits that exceed the costs.arrow_forward
