Emissions trading

Weather trading is just one example of "negative commodities", units of which represent harm rather than good.
"Economy is three fifths of ecology"[cite this quote] argues Mike Nickerson, one of many[who?] economic theorists who holds that nature's productive services and waste disposal services are poorly accounted for. One way to fairly allocate the waste disposal capacity of nature is "cap and trade" market structure that is used to trade toxic emissions rights in the United States, e.g. SO2. This is in effect a "negative commodity", a right to throw something away.
In this market, the atmosphere's capacity to absorb certain amounts of pollutants is measured, divided into units, and traded amongst various market players. Those who emit more SO2 must pay those who emit less. Critics of such schemes argue that unauthorized or unregulated emissions still happen, and that "grandfathering" schemes often permit major polluters, such as the state governments' own agencies, or poorer countries, to expand emissions and take jobs, while the SO2 output still floats over the border and causes death.
In practice, political pressure has overcome most such concerns[citation needed] and it is questionable whether this is a capacity that depends on U.S. clout: The Kyoto Protocol established a similar market in global greenhouse gas emissions without U.S. support.

Commodity markets and protectionism

Developing countries (democratic or not) have been moved to harden their currencies, accept IMF rules, join the WTO, and submit to a broad regime of reforms that amount to a "hedge" against being isolated. China's entry into the WTO signalled the end of truly isolated nations entirely managing their own currency and affairs. The need for stable currency and predictable clearing and rules-based handling of trade disputes, has led to a global trade hegemony - many nations "hedging" on a global scale against each other's anticipated "protectionism", were they to fail to join the WTO.
There are signs, however, that this regime is far from perfect. U.S. trade sanctions against Canadian softwood lumber (within NAFTA) and foreign steel (except for NAFTA partners Canada and Mexico) in 2002 signalled a shift in policy towards a tougher regime perhaps more driven by political concerns - jobs, industrial policy, even sustainable forestry and logging practices.

Proliferation of contracts, terms, and derivatives

However, if there are two or more standards of risk or quality, as there seem to be for electricity or soybeans, it is relatively easy to establish two different contracts to trade in the more and less desirable deliverable separately. If the consumer acceptance and liability problems can be solved, the product can be made interchangeable, and trading in such units can begin.
Since the detailed concerns of industrial and consumer markets vary widely, so do the contracts, and "grades" tend to vary significantly from country to country. A proliferation of contract units, terms, and futures contracts have evolved, combined into an extremely sophisticated range of financial instruments.
These are more than one-to-one representations of units of a given type of commodity, and represent more than simple futures contracts for future deliveries. These serve a variety of purposes from simple gambling to price insurance.

[edit] Oil
Building on the infrastructure and credit and settlement networks established for food and precious metals, many such markets have proliferated drastically in the late 20th century. Oil was the first form of energy so widely traded, and the fluctuations in the oil markets are of particular political interest.
Some commodity market speculation is directly related to the stability of certain states, e.g. during the Persian Gulf War, speculation on the survival of the regime of Saddam Hussein in Iraq. Similar political stability concerns have from time to time driven the price of oil. Some argue that this is not so much a commodity market but more of an assassination market speculating on the survival (or not) of Saddam or other leaders whose personal decisions may cause oil supply to fluctuate by military action.
The oil market is an exception. Most markets are not so tied to the politics of volatile regions - even natural gas tends to be more stable, as it is not traded across oceans by tanker as extensively.

Regulation of commodity markets

Cotton, kilowatt-hours of electricity, board feet of wood, long distance minutes, royalty payments due on artists' works, and other products and services have been traded on markets of varying scale, with varying degrees of success.[citation needed] One issue that presents major difficulty for creators of such instruments is the liability accruing to the purchaser:
Unless the product or service can be guaranteed or insured to be free of liability based on where it came from and how it got to market, e.g. kilowatts must come to market free from legitimate claims for smog death from coal burning plants, wood must be free from claims that it comes from protected forests, royalty payments must be free of claims of plagiarism or piracy, it becomes impossible for sellers to guarantee a uniform delivery.
Generally, governments must provide a common regulatory or insurance standard and some release of liability, or at least a backing of the insurers, before a commodity market can begin trading. This is a major source of controversy in for instance the energy market, where desirability of different kinds of power generation varies drastically. In some markets, e.g. Toronto, Canada, surveys established that customers would pay 10-15% more for energy that was not from coal or nuclear, but strictly from renewable sources such as wind.[citation needed]
In the United States, the principal regulator of commodity and futures markets is the Commodity Futures Trading Commission.

[edit] Size of the market

The trading of commodities consists of direct physical trading and derivatives trading.The commodities markets have seen an upturn in the volume of trading in recent years. In the five years up to 2007, the value of global physical exports of commodities increased by 17% while the notional value outstanding of commodity OTC derivatives increased more than 500% and commodity derivative trading on exchanges more than 200%.[citation needed]
The notional value outstanding of banks’ OTC commodities’ derivatives contracts increased 27% in 2007 to $9.0 trillion. OTC trading accounts for the majority of trading in gold and silver. Overall, precious metals accounted for 8% of OTC commodities derivatives trading in 2007, down from their 55% share a decade earlier as trading in energy derivatives rose.
Global physical and derivative trading of commodities on exchanges increased more than a third in 2007 to reach 1,684 million contracts. Agricultural contracts trading grew by 32% in 2007, energy 29% and industrial metals by 30%. Precious metals trading grew by 3%, with higher volume in New York being partially offset by declining volume in Tokyo. Over 40% of commodities trading on exchanges was conducted on US exchanges and a quarter in China. Trading on exchanges in China and India has gained in importance in recent years due to their emergence as significant commodities consumers and producers. [1]

Early history of commodity markets

Historically, dating from ancient Sumerian use of sheep or goats, or other peoples using pigs, rare seashells, or other items as commodity money, people have sought ways to standardize and trade contracts in the delivery of such items, to render trade itself more smooth and predictable.
Commodity money and commodity markets in a crude early form are believed to have originated in Sumer where small baked clay tokens in the shape of sheep or goats were used in trade. Sealed in clay vessels with a certain number of such tokens, with that number written on the outside, they represented a promise to deliver that number. This made them a form of commodity money - more than an "I.O.U." but less than a guarantee by a nation-state or bank. However, they were also known to contain promises of time and date of delivery - this made them like a modern futures contract. Regardless of the details, it was only possible to verify the number of tokens inside by shaking the vessel or by breaking it, at which point the number or terms written on the outside became subject to doubt. Eventually the tokens disappeared, but the contracts remained on flat tablets. This represented the first system of commodity accounting.
However, the Commodity status of living things is always subject to doubt - it was hard to validate the health or existence of sheep or goats. Excuses for non-delivery were not unknown, and there are recovered Sumerian letters[citation needed] that complain of sickly goats, sheep that had already been fleeced, etc.
If a seller's reputation was good, individual "backers" or "bankers" could decide to take the risk of "clearing" a trade. The observation that trust is always required between market participants later led to credit money. But until relatively modern times, communication and credit were primitive.
Classical civilizations built complex global markets trading gold or silver for spices, cloth, wood and weapons, most of which had standards of quality and timeliness. Considering the many hazards of climate, piracy, theft and abuse of military fiat by rulers of kingdoms along the trade routes, it was a major focus of these civilizations to keep markets open and trading in these scarce commodities. Reputation and clearing became central concerns, and the states which could handle them most effectively became very powerful empires, trusted by many peoples to manage and mediate trade and commerce.

History

The modern commodity markets have their roots in the trading of agricultural products. While wheat and corn, cattle and pigs, were widely traded using standard instruments in the 19th century in the United States, other basic foodstuffs such as soybeans were only added quite recently in most markets.[citation needed] For a commodity market to be established, there must be very broad consensus on the variations in the product that make it acceptable for one purpose or another.
The economic impact of the development of commodity markets is hard to overestimate. Through the 19th century "the exchanges became effective spokesmen for, and innovators of, improvements in transportation, warehousing, and financing, which paved the way to expanded interstate and international trade."[citation needed]

Financial economics

Main article: Financial economics
Financial economics is the branch of economics studying the interrelation of financial variables, such as prices, interest rates and shares, as opposed to those concerning the real economy. Financial economics concentrates on influences of real economic variables on financial ones, in contrast to pure finance.
It studies:
Valuation - Determination of the fair value of an asset
How risky is the asset? (identification of the asset appropriate discount rate)
What cash flows will it produce? (discounting of relevant cash flows)
How does the market price compare to similar assets? (relative valuation)
Are the cash flows dependent on some other asset or event? (derivatives, contingent claim valuation)

[edit] Behavioral finance

Behavioral Finance studies how the psychology of investors or managers affects financial decisions and markets. Behavioral finance has grown over the last few decades to become central to finance.
Behavioral finance includes such topics as:
Empirical studies that demonstrate significant deviations from classical theories.
Models of how psychology affects trading and prices
Forecasting based on these methods.
Studies of experimental asset markets and use of models to forecast experiments.
A strand of behavioral finance has been dubbed Quantitative Behavioral Finance, which uses mathematical and statistical methodology to understand behavioral biases in conjunction with valuation. Some of this endeavor has been lead by Gunduz Caginalp (Professor of Mathematics and Editor of Journal of Behavioral Finance during 2001-2004) and collaborators including Vernon Smith (2002 Nobel Laureate in Economics), David Porter, Don Balenovich, Vladimira Ilieva, Ahmet Duran, Huseyin Merdan). Studies by Jeff Madura, Ray Sturm and others have demonstrated significant behavioral effects in stocks and exchange traded funds. Among other topics, quantitative behavioral finance studies behavioral effects together with the non-classical assumption of the finiteness of assets

Corporate finance

Managerial or corporate finance is the task of providing the funds for a corporation's activities. For small business, this is referred to as SME finance. It generally involves balancing risk and profitability, while attempting to maximize an entity's wealth and the value of its stock.
Long term funds are provided by ownership equity and long-term credit, often in the form of bonds. The balance between these forms the company's capital structure. Short-term funding or working capital is mostly provided by banks extending a line of credit.
Another business decision concerning finance is investment, or fund management. An investment is an acquisition of an asset in the hope that it will maintain or increase its value. In investment management – in choosing a portfolio – one has to decide what, how much and when to invest. To do this, a company must:
Identify relevant objectives and constraints: institution or individual goals, time horizon, risk aversion and tax considerations;
Identify the appropriate strategy: active v. passive – hedging strategy
Measure the portfolio performance
Financial management is duplicate with the financial function of the Accounting profession. However, financial accounting is more concerned with the reporting of historical financial information, while the financial decision is directed toward the future of the firm.

[edit] The main techniques and sectors of the financial industry

An entity whose income exceeds its expenditure can lend or invest the excess income. On the other hand, an entity whose income is less than its expenditure can raise capital by borrowing or selling equity claims, decreasing its expenses, or increasing its income. The lender can find a borrower, a financial intermediary such as a bank, or buy notes or bonds in the bond market. The lender receives interest, the borrower pays a higher interest than the lender receives, and the financial intermediary pockets the difference.
A bank aggregates the activities of many borrowers and lenders. A bank accepts deposits from lenders, on which it pays the interest. The bank then lends these deposits to borrowers. Banks allow borrowers and lenders, of different sizes, to coordinate their activity. Banks are thus compensators of money flows in space.
A specific example of corporate finance is the sale of stock by a company to institutional investors like investment banks, who in turn generally sell it to the public. The stock gives whoever owns it part ownership in that company. If you buy one share of XYZ Inc, and they have 100 shares outstanding (held by investors), you are 1/100 owner of that company. Of course, in return for the stock, the company receives cash, which it uses to expand its business; this process is known as "equity financing". Equity financing mixed with the sale of bonds (or any other debt financing) is called the company's capital structure.
Finance is used by individuals (personal finance), by governments (public finance), by businesses (corporate finance), as well as by a wide variety of organizations including schools and non-profit organizations. In general, the goals of each of the above activities are achieved through the use of appropriate financial instruments and methodologies, with consideration to their institutional setting.
Finance is one of the most important aspects of business management. Without proper financial planning a new enterprise is unlikely to be successful. Managing money (a liquid asset) is essential to ensure a secure future, both for the individual and an organization.
