Q

How to explain this observed pattern of specialization and hence the pattern of interregional/international trade?

A

Economic research focuses on three influences:
− Absolute advantage (section 3.1)
− Comparative advantage (section 3.2)
− Economics of scale and head starts (section 3.3)

Q

Absolute advantage of trade

A

A country has an absolute advantage over another one in the production of a good if it can produce it with fewer resources than the other country.

=In other words, higher absolute productivity in the production of a specific good is a reason for an absolute advantage of a specific country in the production of this good.

Q

consumer surplus

A

Consumer surplus is an economic measurement of consumer benefits resulting from market competition. A consumer surplus happens when the price that consumers pay for a product or service is less than the price they’re willing to pay. It’s a measure of the additional benefit that consumers receive because they’re paying less for something than what they were willing to pay.

Q

producer surplus

A

Producer surplus is the difference between how much a person would be willing to accept for a given quantity of a good versus how much they can receive by selling the good at the market price. The difference or surplus amount is the benefit the producer receives for selling the good in the market.

Q

Absolute advantage gain (problem)

A

-The existence of gains (win win situation) from trade does not suggest that both countries will have the same level of gains from trade
-The total gains from trade for a country as a whole do not suggest that everyone within a country will gain from trade.

Q

Autarky

A

is a situation in which a country does not trade with other countries.
In autarky, each country would have to produce all goods for its own demand

Q

Absolute advantage and trade policy

A

The principle of absolute advantage is a policy suggestion that countries should import goods from other countries where they are produced more efficiently. These countries should then deploy scarce resources to produce goods that they can produce more efficiently.

Q

Explanation Comparative advantage

A

A country has a comparative advantage over another in the production of a good if it can produce it at a lower opportunity cost: i.e. if it has to forgo less of other goods than the other country.

Q

why does trade benefits each country (comparative advantage)

A
  1. they specialize in the production and exporting of goods in which they have a comparative advantage compared to the other country and
  2. The international trade ratio is between the pre-trade (autarky) relative prices. This is the law of comparative advantage.

Q

Total Gains from Trade and the International Trade Ratio

A

-The general effect of specialization and trade is that each country can consume more than it did under autarky

-The gains from trade for countries involved are not the same in size

-The gains from trade depend on the international trade ratio. They are c.p. higher for a country involved when the international trade ratio for its export good is closer to the pre-trade price ratio of the import country

-When both countries fully specialize in the production of the good with a comparative advantage, the world production of both goods and the trade volume is the highest possible, and so are the total gains from trade for each country.

Q

Who benefits the most (comparatif advantages) ?

A

Small Countries :
Smaller countries that open up to trade with larger partners have little ability to lower the relative price of their exports (their terms of trade) through higher supply or to raise the price of their imports through higher demand on the world market

consequence: their trade terms refer to the pre-trade exchange ratio of the largest trading partner

Q

Domestic Adjustments and Gains from Trade

A

-displaced workers (from one industry to another industry)
-more labor –> new workers can become as productive as the old ones, over time, the structural shift in the economy will make everybody better off

real-world adjustment

A

adjustment might take time and face opposition as people are not only consumers who profit from lower prices, but also producers who care about their current jobs.

Q

short-rum (adjustment comparative advantage)

A

-the ability of factors to move between output sectors is limited
–> The workers, plants and equipment cannot switch instantaneously to the expanding export industry for reasons related their specific qualifications and spatial immobility

-factors of production which are specific for the import-competing industry experience a fall in real income and/or employment, whereas factors specific for the export industry win in real income

Q

relative labor Productivity

A

= opportunity cost

29
Q

Comparative Advantage and the Relative Labor Productivity

A

-the key reason for international differences in opportunity costs are differences in relative (not absolute) labor productivity

30
Q

in the reality why ricardian model (comparative advantages) are not applied

A

-Transportation costs reduce or prevent trade, which may cause each country to produce the same good or service. Due to high transportation costs (think about haircuts and auto repairs) non-traded goods and services exist.

-National trade policies allow import-competing industries to survive

-Sector-specific factors of production raise opportunity costs

31
Q

why the concept of comparatives advantage is important

A

-There is broad empirical evidence (for various countries and periods) of the importance of relative productivity for international trade structure)

-The concept of comparative advantage helps explain why countries with overall low productivity develop strong exports in some industries

32
Q

Are low wages a source of a comparative advantage?

A

lower wages abroad are not the source of comparative advantage, but rather the effect of lower labor productivity

–> in contrary wages rise as productivity rises

33
Q

Labor productivity (calculate)

A

is measured by the value of GDP per worker, and wages are measured by the hourly compensation of the average worker.

34
Q

The Heckscher-Ohlin Trade Theory

A

model of international trade based on comparative advantage due to international differences in factor endowments.
–> focuses on trade with many goods and on reasons why one country might be more productive than another in a particular line of production

35
Q

factor endowments

A

The main economic factors of production are land (and other natural resources), labor, real capital, and human capital

donation factorielle : designe l’ensemble des capacités existante de production d’un pays

36
Q

factor’s proportion theorem

A

The country that is abundant in a factor exports the good whose production is intensive in that factor.

37
Q

The Stolper-Samuelson theorem

A

derived from the H-O model
It states that international trade changes distribution of income (in relation to autarky) in each trading country:
1. Owners of the country’s abundant factors of production gain higher relative and real income from trade, but owners of a country’s scarce factors lose
2. Factors of production that are used intensively by the import-competing industry are hurt by the opening to trade

38
Q

Conflict of interest within countries

A

There is a considerable survey evidence that unskilled workers in rich countries are more protectionist than skilled workers and owners of capital, but unskilled workers in poor countries are more in favor of trade than skilled workers.

39
Q

Empirical evidence on the HO model

A

-common technologies across countries
-countries producing the same set of goods with only 2 factors of production
-costless trade which equalizes prices of goods across countries
=direction for the prediction of HO

40
Q

The International Product Life Cycle

A

He pointed out that many manufactured products go through a product life- cycle in which the input requirements and the location of production change over time

41
Q

3 stage of international product life cycle

A
  1. early-stage = new product stage
    –> the production takes place in an innovating firm’s country which is a (high-income) human-capital-abundant country.
  2. middle stage = maturing product stage
    –> The production shifts to other capital-abundant industrialized countries with high demand which become exporters
  3. late stage = standardized product stage
    –> competition from other firms selling similar products pressures companies to shift production to low-cost locations, mostly labor-abundant countries which export this good now to the rest of the world.
42
Q

Shifting Comparative Advantage

A

implies that patterns of comparative advantage are not stable over time. Countries may lose and gain comparative advantage in different products.

43
Q

Product Life Cycle (definition)

A

As products move from a stage of innovation to one of standardization, their factor-intensity changes. This shifts the pattern of comparative advantage. This may change the geography of production and the regional pattern of trade.

44
Q

Economic Development:

A

As countries develop, their relative factor abundance changes towards higher relative abundance of skilled labor and real capital. This might be another reason for a shift in the pattern of comparative advantage, the geography of production and the regional pattern of trade.

45
Q

China’s Export … (where ? )

A

Patterns to the USA

46
Q

In the most recent years, the greatest share of exports is (china to USA)

A

In the most recent years, the greatest share of exports is transacted in the highest skill-intensity sectors, whereas exports were concentrated in the lowest skill-intensity sectors in the earlier years.

47
Q

china’s grows

A

becomes relatively more skill-abundant, the concentration of exports in high-skill sectors steadily increases over time.

48
Q

inter-industry trade

A

international exchange of products between two different industries (like cloth for wheat)
–> with comparative advantage

49
Q

intra-industry trade

A

international trade of similar products made within the same industry (like domestic cars for foreign cars). This trade takes place between similar countries without comparative advantage.

50
Q

the new trade theory

A

was developed by E. Helpman and P. Krugman

New trade theory (NTT) refers to modern economic theory that explains international trade based on economies of scale, network effects, and first-mover advantage

51
Q

most of the world trade is intra or inter-industry ?

A

Intra industry
–> growing importance of intra- industry trade for industrialized developed countries
–> rapidly industrializing developing countries forced economists to elaborate a new set of models

52
Q

economies of scale

A

The production of many goods, is characterized by decreasing average production costs

53
Q

2 types of economies of scale

A

internal and external economies of scale

54
Q

Internal economies of scale

A

A firm’s average cost of production decreases the more output it produces.

55
Q

reason internal economies of scale ( A firm’s average cost of production decreases the more output it produces)

A

-the rent pay for the office, the building, energy cost: they do not double when we double the production
-fix cost: employees
-transportation cost per unit of output will become lower

–> related to the size
–> higher size of the experience, will improve the production

56
Q

Internal Economies of Scale and Imperfect Competition

A

The presence of internal economies of scale is the reason why firms want to grow: size confers a competitive advantage.

57
Q

Oligopoly

A

a handful of firms produce the entire market output, with each firm
formulating its strategies in response to those of its competitors

58
Q

Monopolistic competition

A

each firm produces a slightly different product which is a (imperfect) substitute for another variety. Product differentiation ensures that each firm has a monopoly in its particular product variety within industry, but takes the prices charged by its rivals as given.
Unlike under pure monopoly, competition among many firms exists.

59
Q

Internal economies of scale are important cause of international trade:

A

It pays to concentrate production in only a few locations, so each location has a large level of output. But that also means that production occurs in only a few locations/countries that export the good to other locations/countries

60
Q

The Gains from International Trade with Internal Economies of Scale

A

International trade increases market size for exporting firms and improves the welfare of the individual nations for a number of reasons:

  1. Increase in consumer choices
    2.Lower prices
    3.Overall productivity gains

–> A smaller country tends to gain more from these integration effects than a larger country.

61
Q

external economies of scale

A

are business-enhancing factors that occur outside a company but within the same industry.

62
Q

when firms occur external economies of scale

A

They occur when firms become more productive (have lower average costs) as the size of the entire industry (number of firms or total industry output) increases, but not necessarily the size of any one firm.

63
Q

A cluster

A

is a geographically proximate group of interconnected companies and associated institutions in a particular field, linked by commonalities and complementarities (external economies of scale)

64
Q

origin of external economy of scale

A

dates back to Marshall (1890). Krugman (1991) stated that external economies of scale lead to regional concentration of firms (spatial clusters) and to international trade without comparative advantages.

65
Q

example of spatial Clusters

A

-Tourism and wine
-Semiconductor industry and life science
-Silicon Valley

66
Q

Reasons for External Economies of Scale

A
  1. Specialized suppliers
    2.Labor market pooling
    3.Knowledge spillovers (informal exchange of information, reverse-engineering and sharing ideas by workers of different firms become easier)
67
Q

Dynamic External Economies of Scale Reinforce Regional Concentration

A

1.Geographical concentration may be self-reinforcing:
-The region with an initial small head start in attracting firms may over time
develop significant economies of scale before other regions.
-dynamic increasing returns to scale could arise if the average cost of production depends on the accumulation of knowledge and experience (learning), which depend on the production process over time.

2.a move toward clustering may cause a chain reaction, resulting in a massive industrial agglomeration

  1. An initial small head start may turn into a permanent competitive advantage for firms in one region over another.
68
Q

Trade and Welfare with External Economies

A

1.gains to the world economy by concentrating production of
each industry with external economies

2.opening to trade will lead to specialization and prices that are lower than the prices in either country before trade.

3.Countries that start as large producers in certain industries with external economies tend to remain large producers and exporters even if another country could potentially produce more cheaply.

4.Each country wanting to reap the benefits of housing an industry with economies of scale creates trade conflicts.
