64
Q

Phillips Curve

A

A Keynesian theory about the correlation between unemployment and inflation; as unemployment goes down, inflation goes up, and vice versa.

65
Q

Life-cycle hypothesis

A

Modigliani’s idea that rational individuals don’t consume blindly, but look to the future and develop expectations about how much they need to save toward old age. When they’re older, they use up their savings, trying to keep consumption constant, smoothing its path over time.

66
Q

Permanent income hypothesis

A

Friedman’s theory that people smooth their consumption over time around their permanent income (an expectation of future earnings based mostly on current wealth). Any extra income is transitory and will be saved.

68
Q

Fundamental theorems of welfare economics

A
  1. Any pure free market economy in equilibrium is Pareto efficient, a weak ethical criterion.

71
Q

A

A voting system that truly reflects the preferences of the electorate is impossible. He proposed fairness criteria for an ideal voting system.

Q

Two prisoners, if they agree to stay silent get a brief sentence, if one stays silent and the other betrays then one goes free and the other gets a severe sentence, and if both betray they both get a medium sentence.

93
Q

Lucas critique

A

If individuals’ expectations do adjust with policy, this means that the whole structure of the economy alters with changes in policy. The effects of policy are not always those that are intended.

94
Q

Expected utility

A

The amount of expected satisfaction

Q

Ellsberg paradox/ ambiguity aversion

All investors have access to the same publicly available information as their rivals, so the prices of stocks fully reflect all the knowledge available. No one can know what new information will be released, so it should be almost impossible for investors to make a profit without insider trading.
