Trade Policy

This chapter looks at the policies which either facilitate or impede free trade in the world!

As economists, we usually are in favor of free trade. We recognize that free trade offers many benefits to different countries!

Why is free trade a good idea?
-The law of comparative advantage
-When there is regional specialization and trade, the world production of all products rises
-This maximizes the world's average standard of living (world GDP per capita)

On the other hand, some countries may attempt to instill protectionist policies (policies which counteract free trade in order to protect domestic firms from international competition). These can include both TARIFFS and NON TARIFF BARRIERS (NTBs, such as quotas, customs procedures, anti-dumping duties and countervailing duties).

Why might nation choose certain degrees of protectionism?

REASONS WHICH RELATE TO MAXIMIZING NATIONAL INCOME

1: To improve the terms of trade! If a country is large enough, it can force the world price downward for goods it imports by imposing a Tariff

2: Infant Industry Protection. Some countries may set up trade barriers in order to protect domestic firms from international competition, with the hopes that these industries will grow to the point where they can realize economies of scale. The idea here is that under protection, infant industries will eventually "grow up" to the point where they will be able to compete on the international market without need of protectionism. A problem with this is that not all industries develop to this level of competency while under protection. Canada's national policy of 1876 was an example of infant industry protection directed at improving Canadian manufacturing.

3: Learning by doing. This sort of goes along with infant industry protection, but along with protecting developing industries from international competitors, protectionism can also simply give those industries time to operate, which gives personnel time to gain mastery over certain procedures. In this way, countries can turn comparative disadvantages into comparative advantages.

PROBLEM! Not every industry which gets chosen for protection will ultimately grow up to be an international "winner", so each time the government placed an industry under protection, they are effectively gambling (as protectionism exacts economic costs) on their choice. If governments do this frequently, statistically, they are likely to choose more losers than winners, which would be quite costly.

=(

4: Protectionism can allow certain key industries to earn economic profits and thus innovate more. As such, Canada has strategic trade policy in place with regards to Bombardier (if you remember, they're the company which made the olympic torches)

OTHER REASONS

1: There are advantages from diversification. Countries which are only specialized in a narrow range of products may use protectionism in order to diversify their economies (which gives local firms a "safe space" to expand into new industries, thus increasing the range of products produced domestically). This can be useful in that it buffers the volatility and risk posed by price changes and new technologies by spreading production to several different sectors. The idea here is not to "put all of your eggs in one basket" (although, often, this is more of a political argument than an economic argument)

2: Protectionism lets governments protect favored groups! In Canada, competitive advantage favors skilled labour over unskilled labour, and as a result, free trade may lower the wages of unskilled laborers (who are now competing with wage slaves from overseas). Here, protectionism can redistribute income to certain productive groups, but at the expense of the collective standard of GDP. There is a deadweight loss!

USUALLY, HOWEVER, PROTECTIONISM IS FOR POLITICAL OR FALLACIOUS ECONOMIC REASONS!!!!!!!!! >=(

HERE ARE SOME FAULTY ARGUMENTS WHICH PEOPLE WILL OFTEN POSE IN ORDER TO SUPPORT PROTECTIONISM!

1: "We've got to keep our money at home"
The Premise: If I buy a domestic good, by country will have both the good AND the money used to buy that good
Why it's incorrect: Domestic money is only useful for buying domestic goods. If you are buying foreign products, the money you spend on those products eventually gets used to buy Canadian products- it flows between the two trading countries

2: "We've got to protect ourselves from low-cost foreign labour"
The Premise: Low wage foreign goods will eliminate domestic goods from the market, and thus lower the domestic standard of living.
Why it's incorrect: This goes against the law of comparative advantage. Even if a foreign country can produce all goods at a lower cost than Canada, it would still be advantageous to trade, as trade will lower the opportunity cost of having certain products.

3: "Exports are good, and imports are bad"
The Premise: Exports add to domestic GDP, while imports take away from domestic GDP
Why it's incorrect: Standard of living is dependent on consumption, not production. If a country exports a lot of goods, but derives its comparative advantage by paying its workers very low salaries, then those workers will not be able to consume very many products, on average, and thus that country's standard of living will probably be quite low.

4: "Protectionism creates local jobs"
The Premise: Protecting the domestic market can help save local jobs, and thus combat unemployment
Why it's incorrect: Protectionism reduces employment in other sectors which may have local comparative advantages, and thus, while it may increase employment in one sector, the overall economic effect is inefficient.

-----------------

METHODS OF PROTECTIONISM

TARIFFS: Import Duties- these are a tax on imports. They increase costs for domestic consumers, but benefit domestic producers (who can sell at higher than the world price) and the government (who receives tax revenue). Tariffs create a deadweight social loss for the economy as a whole.


Originally, at the world price, Canada will import 1500 units of this product, and domestic producers will supply the other 500 units needed to satisfy demand.

Once the tariff raises the prices, Canada only imports 500 units of the product, and domestic producers supply the other 1000 units needed to satisfy domestic demand (as you can see, demand has decreased due to the higher price).

Consumer lose surplus represented by sections C, D, E, & F due to the Tariff
Producers gain surplus represented by section C due to the Tariff (the increase in price times the increase in production, minus the costs incurred by increasing production)
The government gains section E due to the Tariff (the quantity of foreign imports at the Tariff price, multiplied by the amount of the Tariff)

SECTIONS D & F REPRESENT A DEADWEIGHT SOCIAL LOSS, HOWEVER! (tragic, isn't it!?)

--------------------------------

QUOTAS AND VOLUNTARY EXPORT RESTRICTIONS (VERs)
An import quota is like a quantity ceiling- it restricts the quantity of products which a country will import
With a voluntary export restriction, the exporter agrees to limit the amount of exports it will send to any one country.
This incurs costs for domestic consumers, but benefits domestic producers
The net result is a deadweight social loss which is greater than that which results from a Tariff!



At the world price, Canada will import Q4 - Q1, and domestic producers will supply Q1
Let's say that a quota restricts domestic imports to Q3 - Q2. If this happens, then the domestic price must rise to P1, where the quota exactly satisfies the excess demand which domestic producers cannot meet.

Consumers lose surplus equal to E, F, G, H, & I due to the quota,
Producers gain surplus equal to E due to the quota
Since there is no taxation here, the higher price on the quota goods causes foreign producers to gain surplus equal to G & H

THERE IS A DEADWEIGHT LOSS EQUAL TO SECTIONS F & I due to the quota! >=(

Usually, in trade barrier situations, exporters prefer a quota (so they can gain the extra revenue section) while importing governments prefer a tariff (so they can gain the extra revenue section).

----------------------------------------

NON-TARIFF BARRIERS

1: Antidumping Duties
-Dumping is the practice of selling a good in a foreign country at a price below domestic prices at a reason other than costs
-This is like price discrimination (remember from micro) but on an international level
-Usually, it is only temporary, in order to sell off excess supply, or to weaken local industries and force reliance on foreign imports
-It is seen as anti-competitive, and many people believe that it is an unfair form of competition
-Antidumping duties (taxes to bring "dumped" imports back up to the domestic price level) are often used to compensate for this
-Recently, however, these have been abused and used as a non-trade barrier
-When Antidumping Duties are used, the domestic price becomes the price floor, regardless of the foreign price (which can lead to an inflexibility in domestic prices compared to the world price)
-As such, if the world price falls below the average costs for domestic producers, they are protected
-Often, the system requires foreign accusers to prove that dumping is occurring in order for antidumping duties to be instated

2: Countervailing duties: a tariff imposed as a trade remedy to counteract foreign governments subsidizing their industries
-Governments wishing to impose countervailing duties must prove that there is a foreign subsidy being used to bolster a certain foreign industry, and that it is significantly harming the prospects of domestic producers
-The U.S. is currently placing countervailing duties on Canadian softwood lumber.

-----------------------

IMPORTANT ORGANIZATIONS AND TERMS

GATT- The general agreement on trades and tariffs: an effort to reduce international protectionism

The Uruguay Round- reduced tariffs by 40%, but failed to deal with European and Canadian agricultural subsidies (eventually, they ended quotas, but replaced them with Tariffs in a process called Tariffication)

WTO- World trade organization- it has 148 members, it is a global organization which deals with the rules of trade, and it endeavors to lower trade and non-trade barriers. It also includes a formal dispute settlement mechanism

Doha Round- tried to reduce agricultural subsidies

The Battle for Seattle- People protested that human, labour, and environmental rights were not being addressed by the WTO. Interestingly, 3rd world countries often argue against considering these in trade deals

MAI- Multilateral agreement on investment: similar to WTO, but for investments

Free trade Area- Goods and services may move freely among member countries, but each member nation still sets barriers against foreign imports on an individual basis (like NAFTA) PROBLEM: Certain Tariffs have grandfather clauses, and thus persist despite agreements.

Customs Union- A free trade area, but with a common set of barriers against foreign imports (like Mercosur: Brazil, Uruguay, Paraguay, and Argentina)

Common Market- A customs union in which factors of production (i.e., workers) may move freely among member nations (like the EU)

THAT'S ALMOST ALL!!!

Gains from International Trade

OKAY! Let's talk turkey about international trade.



Over time, while world GDP had been increasing at a fairly constant rate, world trade has increased exponentially!

Canada is, itself, involved in quite a bit of international trade (we export and import quite a lot of goods)

David Rciardo was an economist of lore (1772-1823), and he was a major proponent of international trade. He wrote "Current comparative advantage is a major determinant of trade under free-market conditions."

Economists who advocated world trade often promoted teachings which led to real changes, such as England repealing its corn laws and moving towards a more open economy (an open economy is one which engages in international free trade, and realizes certain advantages from this, known as the gains from trade).

GAINS FROM TRADE: These are increases in total economic output due to efficiency advantages resulting from local economies engaging in specialization and trade of goods in which they have a comparative advantage.

COMPARATIVE ADVANTAGE: A situation where one local economy can produce a certain good at a lower opportunity cost than other economies (i.e., if it is less expensive for Canada to grow wheat than it is for Haiti to grow wheat, then we would state that Canada has a comparative advantage in wheat)

WHAT IS THE LOGIC BEHIND INTERNATIONAL TRADE? It's the same logic which states that interpersonal trade will be beneficial!
-When there is no trade on an interpersonal level, each individual has to be self-sufficient: they must provide for all of their own needs
-Trade allows individuals to specialize in providing goods and services which they can produce or provide efficiently, and then trade those for goods and services which they are less proficient at providing.

For an example, if I am a Doctor, I could be very very good at fixing coronary blockages, but terrible at fixing pipes. Trade means that I can simply make money by acting as a doctor, and then trade this money to "borrow" a trained plumber, thus saving me hours of frustration and reading complicated instructions. In this situation, both me and the plumber are providing the services which we are most efficient in, and because I don't have to waste time learning how to fix pipe and he doesn't have to waste time memorizing human anatomy, the overall economic output between the two of us is higher! We are more efficient when we can divide and conquer! =D

Well... interregional and international trade follows the same logic!

There are two different sources of gains from international trade:

1- The fact that different local economies have different resource endowments (and therefore can benefit from specializing in producing products which fit well with regional endowments, both natural and acquired)

2- The fact that international trade leads to a larger market for products means that local firms can realize reductions in production costs due to increased production (they are able to achieve economies of scale)

---------------------------------

ABSOLUTE ADVANTAGE: This is when one country (or economy), compared to another, can produce more of a good from the same inputs

So, lets say that given the same inputs...

Canada can produce 10 bushels of wheat or 6 lengths of cloth
England can produce 5 bushels of wheat or 10 lengths of cloth

Canada has an absolute advantage over England in terms of wheat, and England has an absolute advantage of Canada in terms of cloth. Here, we have a situation of reciprocal advantage (each country is more adept at producing a different good), and thus it will be advantageous for England and Canada to trade!

WHY?!

Because each unit of input which Canada switched from cloth production to wheat production leads to 6 fewer cloths, but 10 more wheat. Similarly, each unit of input which England switched from wheat production to cloth production leads to 5 fewer wheat and 10 more cloth. The net effect of this is that the world production of both wheat and cloth has increased if both the countries specialize in what they are best at producing: there are worldwide gains from specialization.

But English and Canadian consumers want to purchase both goods... so unless these countries are able to trade, this specialization would not be practical.

----------------------------

THE LAW OF COMPARATIVE ADVANTAGE

Lets say that using one unit of input...

Canada can produce 100 bushels of wheat or 60 lengths of cloth
England can produce 5 units of wheat or 10 length of cloth

Here, Canada has can absolute advantage in both wheat and cloth (so Canada is more efficient at producing either of these products). Some people might think that Canada should thus not engage in trade... but they would be WRONG! Dead WRONG!

Canada can produce 20 times as much wheat at England, but only 6 times as much cloth using one unit of input. From this, we can surmise that Canada has a COMPARATIVE ADVANTAGE in wheat, while England has a comparative advantage in cloth.

Each country should trade goods in which it has a comparative advantage. Trade, in this case, increases the world's per-capita GDP. Comparative advantage is a necessary and sufficient condition for trade. Absolute advantages (in the absence of comparative advantages) do no lead to gains from trade.

How do we figure out which product a country has a comparative advantage in?

Easy! You just calculate the opportunity cost of producing any one good. Given the previous example, the OC of producing 100 bushels of wheat in Canada is 60 lengths of cloth, so the opportunity cost of each bushel of wheat is 0.6 lengths of cloth. Similarly, the OC of producing is length of cloth is 1.67 bushels of wheat for Canada. The opportunity cost for England of producing 1 length of cloth is 0.50 bushels of wheat, and the opportunity cost for England of producing 1 bushel of wheat is 2 lengths of cloth!

The opportunity cost of wheat is lower in Canada than in England, so Canada has a comparative advantage in wheat
The opportunity cost of cloth is lower in England than in Canada, so England has a comparative advantage in cloth

The point: opportunity cost depends on relative costs, no absolute costs!

WHENEVER OPPORTUNITY COSTS DIFFER, SPECIALIZATION AND TRADE CAN INCREASE THE WORLD PRODUCTION OF BOTH COMMODITIES, WHICH LEADS TO INCREASED CONSUMPTION POSSIBILITIES

*to note: increased production does not necessarily lead to increased consumption, and standard of living depends on consumption rather than production (so a country could produce a whole lot of products, but if its workers make very low factor incomes, and are hence unable to consume many goods, that country's standard of living may still be extremely low.)

ABSOLUTE ADVANTAGE DOES NOT LEAD TO GAINS FROM TRADE!

If Canada can produce 100 wheats or 60 cloths given one unit of input
and England can produce 10 wheats or 6 cloths given one unit of input

Canada has the same absolute advantage of England in terms of both products, but each country has the same opportunity costs in terms of producing each good. Because of this, specialization and trade will NOT lead to any gains for either country, nor will it increase world output of either product.

There are other reasons in addition to comparative advantage that can make it beneficial to engage in specialization and trade

Basically, whenever OC's differ for the same products between different countries, specialization (and subsequent trade) leads to an increase in net production of goods, and as a result, a decrease in costs, because of...

1: Economies of Scale- Trade creates a larger market for domestic producers (who, after international trade, provide products for consumers around the world instead of just domestically)

2: Product Differentiation- A large international market for any type of product leads to further specialization, or product differentiation. For an example, in Europe, each country specializes in intra-industry trade. Between Canada and the U.S., each country specializes in a different type of car.

3: Learning by doing- Larger international markets lead to specialization, which leads to "accumulated experience". For an example, the silicon valley area of the United States has gained a reputation for computerized innovation, and as a result of that specialization, people from that area gain experience over time, and become better-equiped to compete in that industry.

Economies of Scale = Production moves to the bottom of the LRAC
Learning by Doing = The entire LRAC shifts downward, so any level of production costs less

-------------------------------------

SOURCES OF COMPARATIVE ADVANTAGE:

1: Natural Factor Endowments
-This is how traditional economists explained comparative advantages
-What each country is "born with"
-This includes both natural resources and climates, as well as social patterns and institutional set-ups
-This natural resource advantage translates into cost advantages (i.e., a very fertile country will not incur as many costs growing food as an arid country)

2: Acquired Comparative Advantages
-This is a newer idea: what each country DEVELOPS can lead to a comparative advantage in certain products
-For an example, social fixtures such as education, healthcare, and social services can create more productive workers
-Research and development can also lead to innovations and localized experience which gives certain nations comparative advantages in certain sectors (like Canada and aerospace engineering, or Korea and shipbuilding)

-------------------------

PATTERNS OF INTERNATIONAL TRADE:

We know that countries should specialize and then trade in goods in which they have a comparative advantage.

So... do countries actually export those goods in which they have a comparative advantage? The answer is YESSSSSSS!

THE LAW OF ONE WORLD PRICE: Internationally traded goods sell at the same price, regardless of which country they are sold in, assuming
-zero transport costs
-it is actually the same good
-competitive markets
-the good is tradable

World price simply equates global supply and demand for any product to determine the equilibrium price

So.........

If one country has a comparative advantage in a certain product which would potentially lead to a lower domestic price for this product than the world price level, instead of simply selling the product at the domestic price level, that country will sell that product on the world market at the (higher) world price level: the domestic excess supply will get sold off on the international market.

THE THEORY OF COMPARATIVE ADVANTAGE IS STILL RELEVANT~!! Sources of those competitive advantages may have changed over the years, but the basic premise of this theory still holds true!

------------------------------------

TERMS OF TRADE: These determine how the gains from trade are shared- in other words, how will the gains in world per-capita GDP be shared among the trading nations.

The Terms of Trade = the ratio of (the price of exports / the price of imports)
OR
The relative international price of imports (how many imports can be purchased per unit of export)

If the terms of trade increase, this is favorable for the nation in question, because they are able to get more imports per export. The reverse is true if the terms of trade decrease.

Unfavorable terms of trade will not be conducive to trade! Basically, if the terms of trade make it so that the OC of obtaining imports is equal to or greater than the OC of producing a product domestically, the country in question will not trade for that product! There needs to be a win-win situation (terms of trade which allow for both countries to enjoy lowered OCs) in order to trade to occur.

-----------------------

International Trade and the PPC:



When there is trade, consumption can differ from production! This means that trade can facilitate changes in production which allow for patterns of consumption which lie outside the PPC!

The slope of the dotted line = the terms of trade (tt)

Basically, given any point on the original PPC, international trade allows that country to trade products with another country at a rate which differs from that given on the PPC (which is usually convex). As you can see, if the country in the diagram specializes and trades, it can reach point B!

By specializing (changing production), countries can optimize their production in order to best take advantage of good terms of trade!

NOTE: Which country wins depends on the terms of trade (the slope of the line). Also, the consumption pattern (the point on the CPC) which each country settles into will depend on their preferences between the two products being compared.
Also, most countries have increasing OCs with increased specialization, and thus they have convex PPCs


That's all for now!
