TRUE or FALSE: Efficiency means everyone in the economy should receive an equal share of the goods and services produced.
False - this is the definition of equality.
TRUE or FALSE: A rational decision maker takes an action if and only if the marginal cost exceeds the marginal benefit.
False - a rational decision maker would only take action if the marginal cost was lower than the marginal benefit.
TRUE or FALSE: The invisible hand ensures that economic prosperity is distributed equally.
False - The invisible hand works through the price system: The interaction of buyers and sellers determines prices. Each price reflects the good's value to buyers and the cost of producing the good. Prices guide self-interested households and firms to make decisions that, in many cases, maximize society's economic well-being.
TRUE or FALSE: Productivity is defined as the quantity of goods and services produced from each unit of labor input.
True - Productivity is defined as the amount of goods and services produced per unit of labor
One tradeoff society faces is between efficiency and equality. Define each term. If the U.S. government redistributes income from the rich to the poor, explain how this action affects equality as well as efficiency in the economy.
Efficiency is the property of society getting the most it can from its scarce resources. Equality is defined as the property of distributing economic prosperity fairly among the members of society. Often, these two goals conflict. When the government redistributes income from the rich to the poor, it reduces the reward for working hard. Fewer goods and services are produced and the economic pie gets smaller. When the government tries to cut the economic pie into more equal slices, the pie gets smaller. Policies aimed at achieving a more equal distribution of economic well-being, such as the welfare system, try to help those members of society who are most in need. The individual income tax asks the financially successful to contribute more than others to support the government.
Explain how an attempt by the government to lower inflation could cause unemployment to increase in the short-run.
To lower inflation, the government may choose to reduce the money supply in the economy. When the money supply is reduced, prices don't adjust immediately. Lower spending, combined with prices that are too high, reduces sales and causes workers to be laid off. Hence, the lower price level is associated with higher unemployment.

d. the government collects less revenue in total.
C. People work less and produce fewer goods and services
Making rational decisions "at the margin" means that people
a. make those decisions that do not impose a marginal cost.
b. evaluate how easily a decision can be reversed if problems arise.
c. compare the marginal costs and marginal benefits of each decision.
d. always calculate the marginal dollar costs for each decision.
C. compare the marginal costs and marginal benefits of each decision.
