A production possibility frontier that is a straight line sloping down from left to right suggests that:

the opportunity costs of the products are constant.

If an economy has to sacrifice only one unit of good X for each unit of good Y produced throughout the relevant range, then its production possibility frontier has:

a constant negative slope.

Look at the figure Strawberries and Submarines. Suppose the economy now operates at point C. Moving to point E would require that the

eliminate its production of strawberries.

The simplest circular-flow model shows the interaction between households and firms. In this model:

firms supply goods and services to households, which in turn supply factors of production to firms.

The importance of an economic model is that it allows us to:

focus on the effects of only one change at a time.

The production possibility frontier illustrates that:

if all resources of an economy are being used efficiently, more of one good can be produced only if less of another good is produced.

Look at the figure Comparative Advantage. Eastland has a comparative advantage in producing:

oranges only.

Look at the figure Comparative Advantage. Westland has a comparative advantage in producing:

peaches only.

Look at the figure Production Possibilities and Circular-Flow Diagram. Assume the two figures represent the same economy. Suppose that in the circular-flow diagram capital that used to flow to firms producing coconuts now flows to firms producing fish. This adjustment in the economy would be best represented in the production possibilities figure by a move from point A toward:

point B (a decrease in coconut production and an increase in fish production).

Look at the figure Production Possibilities and Circular-Flow Diagram. Assume the two figures represent the same economy. Suppose that in the circular-flow diagram there is a significant decrease in the amount of labor flowing to the firms that produce coconuts. If all other variables remain unchanged, this adjustment in the economy would be best represented in the production possibilities figure by a move from point A toward:

point C (a decrease in coconut production).

Look at the figure Production Possibilities and Circular-Flow Diagram. Assume the two figures represent the same economy. Suppose that in the circular-flow diagram most firms undergo a significant increase in productivity. This results in a significant increase in the output of both coconuts and fish. If all other variables remain unchanged, then the adjustment in this economy would be best represented in the production possibilities figure by a movement from point A toward:

point D (an outward shift of the entire curve).

The table shows the combinations of study and leisure time that can be produced in the 16 waking hours of each day. If a student decides to consume one additional hour of leisure time, how many hours of study time must she give up?

Laurence; programs

Which of the following is FALSE about the circular-flow diagram?

Money flows from households to firms as households offer factors of production for sale.

In a single day, Sarah can produce 10 hamburgers, and Abe can produce 5 hamburgers. Therefore, _____ has a(n) _____ advantage in making hamburgers.

Sarah; absolute

If they produce only hamburgers, in a single day Sarah can produce 10 hamburgers, and Abe can produce 5 hamburgers. If they make milkshakes only, in a single day Sarah can produce 10 milkshakes, and Abe can produce 4 milkshakes. Therefore, _____ has an absolute advantage and a comparative advantage in making _____.

Sarah; milkshakes

US Wheat production: 100 0 US Aluminum product: 0 100 Grmny wheat product: 50 0 Grmny Aluminum product: 0. 100 Look at the table Wheat and Aluminum. The United States and Germany can produce both wheat and aluminum. The table shows, in tonnage, the maximum annual output combinations of wheat and aluminum that can be produced. Which of the following choices represents a possible trade based upon specialization and comparative advantage?
