Unit 4: Primary Product Dependency

Copper mine in Kenya
Many lower-income developing nations still relying on specializing in and exporting low value added primary commodities. The prices of these goods can be volatile on world markets.

When prices fall, an economy will see a sharp reduction in export incomes, an adverse movement in their terms of trade, risks of a higher trade deficit and a danger that a nation will not be able to finance investment in education, healthcare and core infrastructure.

Here are some examples of export dependence for a selection of countries in Sub-Saharan Africa: The data shows the % of total exports in 2010:

1.Angola: 97% oil
2.Ghana: 39% gold, 26% oil, 17% cocoa
3.Kenya: 19% tea, 12% horticulture
4.Nigeria: 90% oil
5.Senegal: 11% fish, 11% phosphate
6.Tanzania: 37% gold
7.Uganda: 18% coffee
8.Zambia: 84% copper

Sub-Saharan Africa (SSA) is often cited as a region where primary sector dependence is very high. SSA’s share in global manufacturing trade remains extremely low.

Questions for discussion:

What are the advantages of focussing on one product?
What are the issues?
Is this the same for every primary product?

What has happened to the Terms of Trade over the last 20 years for SSA?

Opportunity Cost

Opportunity Cost is the BENEFIT forgone when choosing the next best alternative.

Opportunity Cost despite its name is about the benefits or the positive things that you may lose out on if you choose an alternative course of action.

In this video, the opportunity cost of getting a grade A in a test was a happy girlfriend. Both options are positives - the opportunity cost of a grade A is not an unhappy girlfriend. He has to give up a happy girlfriend to get an A in the test. This is why the definition of opportunity cost is the benefit forgone (given up).
Think of it as opportunity lost...





Unit 4; Economic Development

The Economic Development section of Unit 4 was answered relatively badly by the Y13's last year. As a result I am determined to improve the delivery of this by adding more resources for you to look at.

May I suggest that, although we won't be looking at this until after xmas, you read this now and digest the implications.

Developing Countries: Similarities & Differences

Of the 192 member states of the United Nations, only 52 are currently classified as high-income countries. In other words, 140 countries (73 per cent) are still considered developing economies.


The number of people living on less than US$1.25 a day is projected to be 883 million in 2015, compared with 1.4 billion in 2005 and 1.8 billion in 1990. However, much of this progress reflects rapid growth in China and India, while many African countries lag behind

World Bank Income Classification (2012)

As of 1 July 2012, the World Bank income classifications by GNI per capita are as follows:

1.Low income: $1,025 or less
2.Lower middle income: $1,026 to $4,035
3.Upper middle income: $4,036 to $12,475
4.High income: $12,476 or more

Diversity between developing countries
· No two less economically developed countries are the same!
· There is a huge amount of diversity between them
· Think about some of the key structural economic differences between nations – for example:

1.The size of an economy (i.e. population size, basic geography, annual level of national income)
2.Historical background including years since independence from colonial rule
3.Natural resource endowment
4.The age structure of the population
5.Ethnic and religious composition
6.Relative size / importance of public and private sectors of the economy
7.Structural of national output (e.g. primary, secondary, tertiary and quarternary sectors)
8.Structure of international trade (both geographical and the commodity pattern of trade)
9.Political stability, strength of democratic institutions, transparency of government
10.Ethnic and gender equality and tolerance
11.The ease with which new businesses can be created and sustained
12.Other competitiveness indicators including the relative size and strength of high-knowledge / high-technology industries

There are also some common characteristics of developing countries – the list below is not meant to be an exhaustive one, but here these characteristics might include:

1.Relatively low incomes per capita compared to richer advanced nations
2.Lower absolute levels of productivity (labour and capital)
3.A higher dependency on export incomes from primary commodities / low rates of export diversification
4.They have a large share of the population living in rural areas and employed in agriculture
5.A higher than normal “informal” sector of the economy for example in partial subsistence farming
6.Many industries in low-income developing countries tend to be some distance from the technological frontiers reached in rich advanced nations.
7.Relatively fast growth of population and a younger average age – giving a different shape to the population pyramid
8.Weaknesses in critical infrastructure such as telecommunications, transport, ports, water and sanitation and institutions such as stable government, a well functioning civil service and money and capital markets

Unit 1: Positive & Normative Statements

This is an introductory blog note for new students of AS microeconomics. It focuses on positive and normative economics. The cartoon has more to do with Supply & Demand, but I thought it would grab your attention. (You should all read Calvin & Hobbes...brilliant!

Positive Statements

A positive statement is a statement about what is and contains no indication of approval or disapproval. A positive statement can be wrong; it can be tested by objective use of evidence. The tools of positive economics are reason, logic and empiricism.

Normative Statements

A normative statement expresses a value judgment about whether a situation is desirable or undesirable.

"The British economy would be a lot stronger if Sarah Meeajan was Governor of the Bank of England"

is a normative statement because it expresses a judgment about what ought to be. Statements that include indicator words such as: should, ought, or prefer are likely to be normative rather than positive Decide whether the following statements are positive or normative:

Statement


Positive or Normative?

1 The government can reduce obesity by offering a subsidy to low income families when they buy fresh vegetables in the supermarket

2 Luxuries should be taxed more heavily than necessities

3 A rise in the value of the exchange rate will reduce the number of overseas tourists visiting London

4 The Minimum Wage needs to be replaced with a Living Wage of £8 per hour

5 Taxpayers should not have to pay for bail outs to a failing Greek economy

6 Drought in the United States should lead to a rise in the world price of grain

7 Reducing the top rate of income tax to 45% will increase relative poverty in Britain

8 It is right that the European Union has introduced a system of carbon trading as a way of cutting CO2 emissions

9 A reduction in the standard rate of VAT ought to bring about a recovery in consumer spending on many goods and services

10 A rise in the price of petrol will lead to an increase in the demand for rail transport

11 An increase in the rate of inflation will lead inevitably to an increase in unemployment

12 Unemployment is more harmful than inflation

13 The Government might target unemployment rather than inflation in order to achieve an improvement in economic growth

14 As a general rule, people are happier in more equal societies

15 Despite a large increase in income per head, people are no happier today than they were 50 years ago

16 The promotion of happiness is a more important goal than the maximisation of production

Year 12 Challenge..

Hello!

This week your task is to learn/ refresh your memories on Production Possibility Frontiers!

You have two lessons to go over the theory in your groups. In the third lesson we will be having a quiz(!) to see which group has used their time and resources efficiently!

These are the points you need to go over..


  • Definitions/purpose of PPF curves
  • Using PPF curves to illustrate OPPORTUNITY COST NUMERICALLY!
  • How to identify efficient and inefficient allocation of resources
  • How to shift the PPF curve - 8 different ways researched in detail!
  • What influences the shape of the PPF curve and why are some straight lines?

Here are some resources to help you out on your challenge..
