A tariff / quota has two effects

  1. Increase in domestic production, decrease in domestic consumption

  2. Less is consumed, leading to lower gains for trade

New cards
2

Tariffs for ya bitch ass

The tariff reduces consumer surplus, increases producer surplus, creates new
government revenue, and creates deadweight loss (areas B and D). Area D shows
that some mutually beneficial trades go unexploited. Area B shows that tariffs
cause some of the economy’s resources to be wasted on inefficient production.

relates supply and demand to an individual's rationality and his or her
ability to maximize utility or profit.

New cards

Behavioral Economics

The study of psychology as it relates to the economic decision-making
processes of individuals and institutions. The two most important
questions in this field are:
1. Focusing on the mental process behind decisions
2. Improving outcomes by improving decision-making.

New cards
21

Bounded rationality

Making a choice that is close to but not exactly the one that gives you the best payoff—the “good enough” method of decision making.
Choosing the best option requires mental effort, and if it’s too costly, it might
make sense to choose a “good enough” option

New cards
22

Framing bias

the tendency to make a decision based on how the
choices are presented

New cards
23

Status quo bias

a) encouraged consumers to drive less than they otherwise would.
b) encouraged consumers to drive at times when traffic congestion is less of

$350

New cards
60

The optimal consumption bundle


is the one that maximizes a consumer’s total utility

given their budget constraint

New cards
61

Utility Maximizing Rule

Consumer allocates his or her income so that
the last dollar spent on each product yields the same amount of extra
(marginal) utility.

MU / P = MU / P

New cards
62

An increase in the price of good X while holding income and the price of good Y constant will

a) increase the marginal utility provided by good X.
b) increase the marginal utility per dollar spent on good Y.
c) decrease the marginal utility per dollar spent on good X.
d) reduce the individual’s preference for good X

New cards
63

The substitution effect of a good

....of a change in the price of a good is the change in the quantity consumed of that good as the consumer substitutes the good that has become relatively more expensive for the good
that has become relatively less expensive.

New cards
64

The income effect of a good

...of a change in the price of a good is the change in the quantity consumed of a good that results from a change in the consumer’s purchasing power (or real income) due to the change in the price of the good

New cards
65

Giffen good

A very rare inferior good for which the income effect outweighs the substitution effect, and the demand curve slopes upward.

New cards
66

An increase in the price of good X while holding
income and the price of good Y constant will:

have a negative substitution effect, leading the consumer to decrease consumption of good X because of the decrease in the marginal utility per dollar spent on good X

Which consumption bundle is her optimal consumption bundle?

First Step:

Calculate MU of each product

Second Step:

Calculate MU / P of each product

Third Step:

Allocate budget accordingly

Lin has $24. The goal is to allocate her budget to get the most utility per dollar spent.

  • First, buy 1 cowboy hat (cost = $12) and 1 bottle of suntan lotion (cost = $6). This leaves her with $6.

  • With the remaining $6, she should buy another bottle of suntan lotion (since it provides the next highest MU per dollar, which is 20).

When the price of a normal good increases, consumers will decrease their consumption of that good because the good has become more expensive relative to other goods

This effect, called the substitution effect, holds for inferior goods, as well.

Physical capital:

often referred to simply as “capital”—consists of manufactured productive resources such as equipment, buildings, tools, and machines

Suppose the marginal cost of hiring an additional unit of labor is $10 and the value of the marginal product from hiring this additional unit of labor is $12. To maximize profit, this firm should hire

more labor

New cards
77

The equilibrium wage rate is $18. A perfectly competitive firm sells widgets for $8. Suppose the marginal product of the sixth unit of labor is three widgets and the marginal product of the ninth unit of labor is two widgets. This firm should hire:

more than six but fewer than nine units of labor.

New cards
78

Three main causes of shifts in the
factor demand curves:

1. changes in prices of output
2. changes in supply of other factors
3. changes in technology

New cards
79

Efficiency wages

 Refer to employers paying higher than the minimum wage to retain
skilled workers, increase productivity, or ensure loyalty
 A type of incentive scheme to motivate workers to work hard and
to reduce worker turnover.

New cards
80

The substitution effect:


A rise in the wage rate raises the opportunity cost

of leisure. There is an incentive to work more, because leisure is relatively
more expensive than working or consumption.

New cards
81

The income effect:


A rise in the wage rate makes you richer. There is an incentive to work less and buy yourself more leisure, because leisure is a normal good

New cards
82

When an individual’s labor supply curve is downward-sloping, this implies that the individual’s income effect is:

stronger than the individual’s substitution effect.

New cards
83

Asymmetric Information

A situation where one party to a market transaction has much more information
about a product or service than the other. The result may be an under- or over-
allocation of resources

New cards
84

Asymmetric Information ex

 Hiring
 Banks Underwriting Loans
 Health Insurance
 Securities Industry

New cards
85


Adverse selection

When information known by the first party to a contract or agreement is not known by the second and, as a result, the second party incurs major costs

New cards
86

How to Mitigate Adverse Selection

  1. Screening: describes the efforts of the less informed party (insurance
    company, employer) to gather information about the more informed
    party (consumers, employee)

  1. Signaling: Describes the efforts of the more informed parties
    (consumers, employees) to reveal information about themselves to
    the less informed party (insurance company, employer

Moral hazard

The moral hazard problem is the tendency of one party to a contract or
agreement to alter her or his behavior, after the contract is signed, in ways that
could be costly to the other party.

New cards
88

Moral hazard ex

 Private firms that go public
 Too big to Fail
 Car insurance
 State Budgets

New cards
89

SOLUTIONS FOR MORAL HAZARD

 Deductible: a sum that the insured individual must pay before
being compensated for a claim.
 Insurance companies deal with moral hazard by requiring a
deductible: they compensate for losses only above a certain amount,
so that coverage is always less than 100 percent
