failures in financial regulation and supervision ○ Dramatic failures of corporate governance and risk management at many systemically important financial institutions ○ Excessive borrowing, risky investments, and lack of transparency ○ Inconsistent response of an ill prepared government ○ Collapsing mortgage­lending standards and the mortgage securitization pipeline ○ Over­the­counter derivatives contributed significantly ○ Failures of the credit rating agencies were essential cogs in the wheel of financial destruction ● 10 essential causes identified by the dissenters: ○ Credit bubble ○ Housing bubble ○ Nontraditional mortgages ○ Credit ratings and securitization ○ Financial institutions concentrated correlated risks ○ Leverage and liquidity risk ○ Risk of contagion ○ Common shock (the fall in housing prices) ○ Financial shock and panic ○ Financial crisis causes economic crisis TARP, Bailouts, and the Stimulus ● The Bush administration and Congress created the Troubled

2005 by 10 northeastern U.S. states ○ To operate a cap­and­trade system for reducing greenhouse gases emissions ○ Auctioned 86 percent of the allowances generating $790 million through 2010 ● Supported by companies that benefited from the funds generated by the auctions ○ Other companies argued that it drove up costs and drove jobs away The Environmental Protection Agency (EPA) ● An independent agency located in the executive branch ● Headed by an administrator appointed by the president and confirmed by the Senate ● Responsible for administering the major environmental acts Enforcement ● The EPA enforcement process requires: ○ Filing of a notice of a complaint and a hearing before an administrative law judge Standards Setting and Engineering Control ● EPA regulation has largely been command and control ○ Uniform rules or standards are ordered and then enforced ● The EPA sets emissions standards and air quality standards ● EPA has increasingly used incentive approaches: ○ Credits and offsets Superfund ● Administered by the EPA ○ For the cleanup of existing toxic waste disposal sites ● EPA attempts to identify the source of the dumping and force it to clean the site The Nature of Environmental Politics ● Environmental issues are complex because of: ○ Scientific uncertainty about the consequences of pollution ○ Incomplete information about the costs and benefits of environmental protection ○ Disagreements about alternative approaches, such as liability versus regulation, to protection ○ Differing perspectives about the protection of entitlements Judicial Politics ● Politics of environmental protection often moves into judicial arenas ● Environmental groups have succeeded in inserting citizen provisions in environmental statutes Advocacy Science ● Much remains unknown about environmental hazards and their control ○ This scientific uncertainty is a source of contention in environmental politics ○ It provides an opportunity to use advocacy science as a component of a private politics strategy Distributive Politics ● Environmental politics is motivated by: ○ Distributive consequences of environmental policy ○ Costs of environmental protection ○ Benefits from the reduction in pollution and hazards Private and Public Politics ● Many environmental NGOs active in public politics at the federal, state, and local levels

operational level to: ○ Achieve performance goals ○ Address challenges ○ Seize opportunities Investment Decisions ● In making their decisions, investors assess: ○ Opportunities and risks associated with firms ○ Quality of their management ● The assessment of managerial quality depends on: ○ A firm’s leadership and market strategy ○ A firm's nonmarket strategy ○ The ability of management to anticipate and deal effectively with the emergence and development of nonmarket issues The Environment of Wind and Solar Power ● Long­term opportunities for wind and solar power were enormous ○ Supply costs were falling ○ Demand for renewable power was expected to continue to grow ○ Demand growth had been led by Europe as a result of generous subsidies ■ As the subsidies were reduced, growth slowed ○ At the same time demand grew in China and the United States ■ More countries began to support wind and solar power ○ Demand was expected to grow substantially in China and developing nations ● Growth hinged on government support and the cost of other energy sources Markets and Government Involvement ● Retail electricity prices varied greatly across the states ○ Both solar and wind power were quite variable ■ Solar power output depended on the weather ■ Wind power was most attractive in locations where the wind blows hard and steadily ○ Solar/wind power faced nonmarket opposition because of: ■ The cost of subsidization ■ Environmental NIMBY Market Signal ● Market for solar panels in Europe and the United States slowed to a crawl in 2010 ○ Market in China grew at a rapid pace Economic Rationale for Subsidization ● Economic rationales for the subsidization of renewable power: ○ Based on positive externalities ■ Subsidization provides environmental improvements by displacing carbon­based power generated from coal or natural gas ■ Subsidization provides security benefits to the extent that it reduced the dependence on imported fuels ○ Intended to achieve cost efficiencies and increased output ■ Subsidies could enable producers to realize economies of scale that would reduce costs and allow output to expand Political Rationale for Subsidization ● Positive externalities for the environment and security benefitted constituents ● Subsidization generated pork: ○ Recipients of the subsidies and their suppliers earned rents from the economic activity stimulated by the subsidization The Costs of Subsidization ● Direct costs of subsidies are the corresponding government budget expenditures and liabilities ○ Examples ­ Grants and loan guaranties Solyndra Inc ● In 2008 Solyndra and Solar Power, Inc., a leading installer of solar panels, agreed to a supply arrangement for$325 million of solar panels over the 2008–2012 period ● Market risks: Prices and costs ● Non
