Q

The Coase Theorem

A

The Coase Theorem is a proposition that if private parties can bargain without cost over the allocation of resources, they can solve the problem of externalities on their own.

But:

  • Each party tries to hold out for a better deal.
  • Asymmetric Information and Irrational Behaviour.
  • Transaction costs are incurred in the process of agreeing to and following through on a bargain.

Q

Adverse Selection

A

When buyers and sellers have different information, it is known as a state of asymmetric information. Traders with better private information about the quality of a product will selectively participate in trades which benefit them the most, at the expense of the other trader. A textbook example is Akerlof’s market for lemons.

Q

Prospect theory

A

Prospect theory is a behavioral economic theory that describes the way people choose between probabilistic alternatives that involve risk, where the probabilities of outcomes are known. The theory states that people make decisions based on the potential value of losses and gains rather than the final outcome, and that people evaluate these losses and gains using certain heuristics.

Q

2 Important differences between monopolistic competition and perfect competition

A
  1. Excess Capacity
  • In monopolistic competition, output is less than the efficient scale of perfect competition.
    2. Mark-up Over MC
  • For a monopolistically competitive firm, price exceeds marginal cost.
32
Q

2 Externalities of entry into a monopolistically competitive market

A
  1. Product Variety for consumers
  2. Stealing Customers from Other businesses
33
Q

Pros and Cons of advertising

A

Cons:

  • Firms advertise in order to manipulate people’s tastes.
  • It impedes competition by implying that products are more different than they really are.

Pros:

  • The willingness of a firm to spend advertising dollars can be a signal to consumers about the quality of the product being offered.
  • Greater Information and Competition
34
Q

Theory of Contestable markets (Baumol, Panzar and WIllig, 1982)

A

Firms are influenced by the threat of new entrants into a market. Therefore firms try to limit this threat:

  • Entry limit pricing is a situation where a firm will keep prices lower than they could be in order to deter new entrants.
  • Predatory pricing
  • Competittive advantage
  • Aggressive marketing
  • Hit ‘n’ Run
35
Q

What are coordination games?

A

A game is a coordination game if players wish to make mutually consistent decisions.

Coordination games can lead to inefficient outcomes when players either miscoordinate, or if they coordinate on actions which do not yield the highest payoffs.

36
Q

Q

Happenstance data

A

the by-product of (uncontrolled) naturally occurring economic activity e.g. inflation, GDP, interest rates

  2. Random (changes over time so you might end up working with a stranger)
  3. Perfect-Random
41
Q

Between vs. Within Subject Design

A

A within-subjects design is a type of experimental design in which all participants are exposed to every treatment or condition.

(+) the best control group

(-) all of the above pros, plus it requires tests for sequencing effects

Between subject design is often called an independent measures design because every participant is only subjected to a single treatment.

(+) unaware of other treatments (reveal goal), subjects not influenced by other treatment (status quo), time to run more repetitions

(-) control group is not identical

42
Q

What did Keynes mean by the Beauty Contest?

A

Keynes believed that similar behavior was at work within the stock market. This would have people pricing shares not based on what they think their fundamental value is, but rather on what they think everyone else thinks their value is, or what everybody else would predict the average assessment of value to be.

43
Q

Why do people reject under 40% propositions in an ultimate games?

A
  1. Inequality aversiion

2 NEgative reciprocity

44
Q

3 Axioms of Ratonal Choice

A

™Completeness:

  • –If we have two bundles of goods, A and B then we can compare them to each other and get a stable preference ordering – i.e. either A is preferred to B, or B is preferred to A, or they are equally preferred.

™Transitivity:

  • –If bundle A is preferred to bundle B, and if bundle B is preferred to bundle C, then bundle A is preferred to bundle C (think about it!).

™Monotonicity (more is better):

  • –If bundles A and B contain the same types of goods (e.g. both are composed of Snickers bars and Starbucks coffees), and bundle A has more of at least one good than bundle B (and not less of either), then bundle A is preferred to bundle B.
45
Q

Anchoring

A

™In many situations, people make decisions by first referring to a known starting point or anchor and then adjusting this anchor up or down according to what they think is right.

There are two types: Internal + External

46
Q

Availability Heuristic

A

™Availability is a heuristic whereby the likelihood of a particular outcome occurring (e.g. the probability of a terror attack) is assessed by the ease with which you can recall examples of the outcome actually happening.

47
Q

Salience

A

™Salience is when information that stands out, seems novel, or seems relevant is more likely to affect our thinking and actions (Dolan et al, 2010).

48
Q

Representativeness bias

A

™Representativeness is when we try to assess the likelihood of something occurring by looking at its similarity to other known occurrences.

49
Q

The law of small numbers

A

–the law of small numbers, whereby people often reach conclusions from observing only a small sample of occurrences, without analysing in any further detail (which takes time and effort).

50
Q

Framing Effect

A

The framing effect is an example of cognitive bias, in which people react to a particular choice in different ways depending on how it is presented; e.g. as a loss or as a gain.

51
Q

Dynamic Inconsistency

A

™Dynamic Inconsistency: When an individual’s preferred or optimal choice at one point in time is no longer his/her preferred option at another point in time. This leads to a misalignment or inconsistency of preferences over time (almost as though you’re a completely different person at different points in time).

52
Q

Long-run economic growth is due to:

A

– Increases in the labour supply.

– Accumulation of physical capital.

– Accumulation of human capital.

– Discovery of natural resources.

– Technological progress.

53
Q

Recession vs Depression

A

A recession is defined as two consecutive quarters of negative economic growth.

A depression is a severe recession (the definition of a depression is subjective).

54
Q

Business Cycles

A

Fluctuations in economic growth around the trend growth rate

  • Procyclical variables (Move in the same direction as GDP)
  • Countercyclical variables (Move in the opposite direction)
55
Q

Leading vs Lagging vs Coincident Indicators

A

A leading indicator is a variable which changes before the change in economic activity. E.g. Stock market performance

A lagging indicator is a variable which changes after the change in real GDP. E.g. Debt relative to Income

A coincident indicator is a variable which changes at the same time as real GDP. E.g. Personal Income

56
Q

Why does the Short-Run AS slope upwards?

A
  1. Sticky wage theory
    - This implies that an unexpected change in the overall price level may not be immediately met by a change in the wage rate.
  2. Sticky Price theory
  • If the overall price level in the economy falls unexpectedly, some firms might lag behind and will be stuck with prices that are “too high.”
    3. Misperceptions Theory
  • Changes in the overall price level temporary mislead suppliers into increasing/decreasing their production due to misperception of why the prices have changed.
57
Q

Theory of Liquidity prefernces

A

– The demand for money comes from households and firms, who choose how much of their wealth to hold in the form of money.

– The supply of money is determined by the central bank.

– For any given price level, the interest rate adjusts to balance the supply and demand for money.

58
Q

Crowding-out effect

A

The crowding out effect is the offset in aggregate demand that results when an increase in government spending raises the interest rate (therefore lower investment).

59
Q

Inside vs Outside lags

A

An inside lag is the amount of time that it takes for policymakers to respond to shocks.

An outside lag is the amount of time that it takes for a policy to have the intended effect on the economy.

60
Q

Benefits of Common Currency Areas

A

– Political benefits

– Transplanted price stability

– No need to hold reserves of each other’s currency

– A common currency is more likely to be a global reserve currency

– Reduction in price discrimination

– Elimination of transaction costs

– Reduction in foreign exchange volatility

61
Q

Costs of joining a currency union

A
  • One-off costs
  • More difficult to cope with economic fluctuations

A

Push factors = Negative incentives that push people away from their country of origi.

Pull Factors = Positive incentives that pull people towards a new country.

64
Q

Stay vs Stay Away (Economic Immigration)

A

Stay = Positive factors that make people want to stay in their country of origin

65
Q

Formal Entry/Exit Barriers (Economic Immigration)

A

Entry = Visa

Exit = North Korean Snipers

66
Q

Costs of Moving (Economic Immigration)

A

67
Q

Possible costs of immigration

A

– Fiscal strains on the host country’s government.

– Lower wages in the host country in certain sectors.

– Lower overall incomes in the source country.

– Social tension.

68
Q

VMPL Curve

A

Marginal Product of Labour x Price = VMPL

  • Downward sloping because of diminshing marginal product of labour
69
Q

Labour Supply curve (Economics of immigration)

A

Assumed Vertical because of ambiguity.

70
Q

Labour Market Model of Immigration Graph and Show which area = $ received by the worker and which are = $ received by the capital owner

A
71
Q

Implications of the Labour Market Model of Immigration

A
  1. Immigration tends to increase wages in the origin country and lower wage in the destination country
  2. Economic forces which create wage differences will also create migration
  3. Immigration creates winners and losers
    - e.g. Capital owners win from immigration
72
Q

Immigration surplus

A
  • Total benefit to the citizens in the destination country = larger than the cost of employing the new workers.
73
Q

Ways immigrants stimulate indirect growth

A
  1. Immigrant = Consumer
  2. Immigrant = Innovator (Knowledge + Right Personalities)
74
Q

Indirect costs of immigration

A
  1. Remittances (Money back to home countries)
    - Depends how they are used
    - Dutch Disease (Increase in recipient country’s exchange rate)
  2. Brain Drain
    - Fiscal repercussions (High-skilled workers tended to pay most tax)
    - Long-term development implications
75
Q

3 Factors that mitigate the negative effects of a brain drain

A
  1. Remittances
  2. Increase in expected returns of human capital investment
  3. Technological transfers (due to social ties)
76
