Lecture 31 Summary and Notes

From the Plundered Planet Book Group...

Plundered Planet Paul Collier

General message:
How to use natural assets: nature + technology + regulation = prosperity
- Without regulation, you get plunder
- Without technology, you get hunger

The book sets out to try to solve the dilemmas that arise from natural assets in low-income countries. He writes that economics and environmental studies need each other and can be compatible.

Part I: Resource curse
Studies have found that countries with higher amounts of natural resources have slower economic growth than countries that do not; similarly, the absence of resources in democratic societies increased economic growth, and democratic countries with an abundance of resources have more economic troubles. So, are resources a curse?
It seems that resources are a curse in countries that have deeper issues. Remember the difference between Sierra Leone and Botswana and Nigeria and Norway.
countries with a comparative advantage should specialize it should use it to trade with other countries; some countries specialize in resource extraction which hinders other developments
Basically, weak or corrupt governance and non-agricultural resources make the asset of natural resources into a curse because there is no proper regulation of the extraction and distribution of natural resources.

Part II: Discovering natural assets
Natural assets lack owners so they can be plundered more easily. Collier divides the world into four quadrants: OECD: Russia/China/satellite nations; Emerging economies; Countries of the bottom billion
What is surprising about the poorer countries is that they tend to be resource-rich countries at present. This isn’t because the land has a greater amount of natural resources (because Africa was not naturally endowed with as many subsoil resources). The difference is that richer countries have been extracting resources for a longer period of time.
Collier highlights that for the bottom billion it is important to think of assets are an opportunity
Problems with natural assets in these countries:
- Tend to be located disproportionately in “difficult” territories
- Only ¼ of natural assets have been discovered in the botton bill compared to rich countries which means something mustve gone wrong
- Discovering what’s underground = EXPENSIVE
Collier’s solution: think of searching for assets as a public good
- Best to allow one entity to make search, let foreign enterprise perform the search b/c it’s so expensive (or even donors like the World Bank or the IMF and these donors could help multiple countries but it’s hard to get them to do this b/c they want to do more “picturesque” jobs like schools)
- Make geological info available as a public good
- Info clarifies what the resources/geological territories are worth so the gov can know how to sell these plots of land

Part III: Capturing Natural Assets
The problems that arise in the phase of capturing natural assets are corruption and underdevelopment.
- Corruption: extraction/discovery relies on extraction companies and the government to get revenues from resources to the country/its people
- Underdevelopment: revenue isn’t used domestically so the country can’t be improved and there is no increase in money in their market
Collier’s solutions:
- Transparency is needed when discovering resources (publish what you pay/EITI)
- Auction off rights to the resources (4 companies competing, will get true value of the resources, eliminates asymmetric info problem)
Extra hindrance:
- Taxes create problems: inefficiency in government and economy; creates uncertainty for companies who want to extract resources; companies try to dodge funky taxes which hurts the country’s revenue
o Contingencies: try to solve inefficiency; agree on a system of taxes ahead of time
o Royalties: reduces asymmetric info; tax on revenue
Overall solution Government should use tax structure w/ contingencies; transparency of companies and government; use royalties b/c they are observable (should be in tax code); legally-binding tax code

Part IV: Selling the Family Silver
Problem: How do we make sure the revenues are being used within the country (benefit future and present generations)
- Governments must balance consumption and savings
- Try to sustain economy with sustainable infrastructure rather than depleting resources
Solution: yield rate of return while the asset is still in the ground
- At what rate should we spend, save, invest (domestically and abroad)
o Norway invest 100% into capital markets and consume less at the beginning of extraction of natural resources
o Ghana spent too early and too much once they discovered early
o Boom and bust cycles: use savings in bust cycles; save a lot during boom cycles
o Long-term infrastructure deals are good but they should be made public for rights to resource extraction

Part V: Investing in Investing
- Most difficult part, but also must important
- Invest in public goods
o Get rid of corruption/ improve management of investment
o Need to promote big-scale projects
- Encourage private investment
o Lessens risk on government
o Mobility in market
- Lower price of capital goods
o Suggests trying to reach trade agreements with other countries or partnering with neighboring countries
- Use examples like Botswana and Malaysia rather than Norway

Lecture 30 Summary and Notes

Some questions for the day...

1. What are the two different types of diamond deposits? How do they differ from the viewpoint of a prospector? How does the morphology of the mine differ based on type of deposit? Which type of deposit depends on the high density of diamonds relative to most other common crustal materials?

2. What is the evidence that there has been a kimberlite eruption in Rockbridge County? How can you be certain that this kimberlite is not diamondiferous?

3. What is unique/special about the formation processes, physical properties, and societal valuation of diamonds out of all of the gems, and other MSI that we have and will discuss in this class?

4. How has the advertising of diamonds evolved since the origin of the "A Diamond is forever" campaign in the late 1940s. How is the marketing/advertising of diamonds an example of a manufactured desire? How does the role of a diamond in the US engagement ritual factor in this manufactured desire? What was the average retail price for a diamond engagement ring in 2011? What is the "standard" equation used in the the calculation of how much should be spent on a diamond engagement ring? Who created this standard and why was the standard created in the first place? According to www.engagementringcalculator.com, will a proposal in which one (or more) parties is pregnant require a more or less expensive ring?

5. What are the 4 Cs? How do two of the Cs describe the composition of the diamond at different scales? How has the inflation-adjusted, wholesale price per carat changed over the past 50 years? What is the current wholesale price for a 1.00 carat, colorless (D), internally flawless, brilliant (round) cut diamond? What about the retail price for the same diamond?

6. What is the Kimberley Process Certification Scheme? What was the reason that Global Witness cited for leaving the Kimberly Process in late 2011?

7. What are conflict diamonds? Why are conflict diamonds an American problem? According to the WDC, what percent of blood diamonds currently come from conflict zones? According to the UN, what percent of blood diamonds currently come from conflict zones? Why is there such a wide gulf in between these two estimates? What were the respective roles of Sierra Leone and Liberia in the diamonds that helped to fund the WTC attacks on 9/11? Why are the DRC and Zimbabwe considered two potential sources for conflict/illegally traded diamonds? What are some of the things that you should look for when trying to source (or avoid sourcing) smuggled diamonds?

8. Is the statement by World Diamond Counsel chairman Eli Izhakoff that the industry knew nothing of the conflict-diamond trade until 1999-2000 indicative of willful deceit or stunning incompetence?

9. Can you use smuggleability in a sentence?

Lecture 25 Summary and Notes

Some questions for the day...

1. What pollutants (general categories)will the new mercury standards (MATS) for US power plants regulate? Why is this new regulation significant? How many power plants are expected to retire as a result of the new regulations? What are the expected effects of the MATS on the consumer price of electricity? What are the benefits that are predicted by the EPA?

2. Coal, NG, oil, and biomass can all be used to generate steam to make electricity. What are the differences between these different combustion sources in terms of "peaking" ability, CO2 flux per unit electricity generated, potential pollutants, US reserve volume, and price?

What are some of the mechanisms through which carbon move from reservoir to reservoir? How does the combustion of fossil fuels affect (disturb) the carbon cycle? Where does the carbon that used to be in fossil fuels end up after combustion? Why is more carbon in the ocean a problem? Why is more carbon in the atmosphere a problem?

4. Why is the regulation of CO2 pollution so difficult? How is our classical thinking about defining 'acceptable' risk largely inadequate for dealing with CO2 pollution? How would the predefined probability approach be applied for CO2 pollution? How would the 'currently tolerated approach to defining 'acceptable' risk be applied to CO2 pollution? How would economic approaches like cost-benefit and cost-utility analysis- particularly in a multi-risk assessment be applied for CO2 pollution? In such a scenario, who bears the cost of pollution reduction? Who benefits from risk reduction related to pollution reduction?
