L24-Public Policies towards Pollution

Here are some optional readings and videos.

1. This article reports that the Pope's encyclical on climate change states, "The strategy of buying and selling emissions credits can give rise to a new form of speculation and would not serve to reduce the global emission of polluting gas. This system seems to be a quick and easy solution with the appearance of a certain commitment to the environment, which however does not imply by any means a radical change in the scale of circumstances. Thus, it may become an expedient that supports continued excessive consumption by certain countries and sectors."
2. Watch MRUniversity A Deeper Look at Tradeable Allowances. It includes a nice comparison of using taxes to reduce pollution with using cap and trade. EcoGeek on cap and trade, carbon. He discusses some of the common arguments against cap and trade.
3. Environmental defense fund on cap and trade, sulfur dioxide. It doesn't describe how the government creates the cap. It does discuss that cap and trade achieves a given reduction in pollution at a lower cost than command and control.
4. This article is a nice summary of carbon taxes around the world.
5. This article is a nice definition of a carbon tax and its effects.
6. Video: Carbon Tax from Australia,
7. Clip on cap and trade. It talks about how the UN distributes permits to emit CO2 to countries who signed the Kyoto Protocol. The US did not sign the Kyoto Protocol.
8. Annie Leonard is not a fan of cap and trade

TOPICS: Internet

SUMMARY: Computing hardware has long served as the critical backbone of business operations. Today, the Internet economy is powered by an infrastructure that has become virtual, and is controlled by a small handful of tech giants.

CLASSROOM APPLICATION: Students can evaluate the effect of economies of scale and network externalities (which are not mentioned in the article) on barriers to entry and ultimately the market power of the noted tech companies.

QUESTIONS: 
1. (Introductory) Evaluate this statement in terms of economies of scale and barriers to entry into the relevant industries: "All of these companies are operating in industries where scale is rewarded and where there is a very high level of capital intensity required to even hope to compete," said Karl Keirstead a senior analyst with Deutsche Bank Securities.

2. (Advanced) Evaluate this statement in terms of the market power of tech firms: "These companies are delivering online search, messaging, advertising, applications, computing and storage on demand-which has positioned them not only to empower business but to extract extraordinary value as it grows." Interpret "positioned them" in terms of economies of scale and barriers to entry.

3. (Advanced) Define "natural monopoly" and "network externalities." Do economies of scale and network externalities in the noted tech industries drive barriers to entry and ultimately the market power of the established players in these industries?

A good example of a near monopoly (80% market share)

Luxottica produces about 80% of the frames for sun- and eye glasses. Moreover, it has achieved this dominant position with little help from the government, as far as I can tell. Here is an excellent account of the predictable effects: http://www.forbes.com/sites/anaswanson/2014/09/10/meet-the-four-eyed-eight-tentacled-monopoly-that-is-making-your-glasses-so-expensive/.

The California electricity crisis

Here is a a nice description of the California electricity crisis: https://en.wikipedia.org/wiki/California_electricity_crisis. Here are some money quotes.

"California had a shortage of electricity supply caused by market manipulations, illegal shutdowns of pipelines by the Texas energy consortium Enron, and capped retail electricity prices." (Highlight added from emphasis.)

"the Death Star group of scams played on the market rules which required the state to pay 'congestion fees' to alleviate congestion on major power lines". Who set and enforced the market rules? Answer: a regulatory board in CA.

Cronyism v. Free Markets

This report is an excellent description of the differences between what I mean when I talk about the market system and what most people mean when they talk about crony capitalism. If the market system = capitalism, then crony capitalism not = capitalism.

Product differentiation

This episode from Planet Money is a good introduction to product differentiation. Is differentiation based merely on brand or perception different than differentiation based on differences in physical characteristics or performance?

Can truth in advertising deceive?

This article reports that the FCC plans to fine ATT for advertising that its data plan was "unlimited" when the plan slowed down data speeds after the customer hit 5GB in the billing cycle.

1. Was the claim that the plan was unlimited true?
2. Was the ad informative?
3. Was the ad deceptive?
4. Did the ad help the consumers make better choices?

A cute example of product differentiation

Rule of Law

http://www.wsj.com/articles/rule-of-law-is-necessary-for-capitalist-prosperity-1446231687

This letter to the editor of the WSJ does a good job stating that Adam Smith's statement that 'By pursuing his own interest [an individual] frequently promotes that of the society more effectually than when he really intends to promote it' "really only works in societies that are dominated by a 'rule of law' mindset."

I am not sure if I agree with the writer's statements about the cultural divide between rule of men and rule of law. They are intriguing.
