Tertiary sector of the economy
–
The tertiary sector or service sector is the third of the three economic sectors of the three-sector theory. The others are the secondary sector, and the primary sector, the basic characteristic of this sector is the production of services instead of end products. Services include attention, advice, access, experience, and discussion, the production of information has long been regarded as a service, but some economists now attribute it to a fourth sector, the quaternary sector. The tertiary sector of industry involves the provision of services to businesses as well as final consumers. The goods may be transformed in the process of providing the service, however, the focus is on people interacting with people and serving the customer rather than transforming physical goods. It is sometimes hard to define whether a company is part of the secondary or tertiary sector. These governmental classification systems have a hierarchy that reflects whether the economic goods are tangible or intangible. Unlike governmental classification systems, the first level of market-based classification systems divides the economy into functionally related markets or industries, the second or third level of these hierarchies then reflects whether goods or services are produced. For the last 100 years, there has been a shift from the primary and secondary sectors to the tertiary sector in industrialised countries. The tertiary sector is now the largest sector of the economy in the Western world and these are not necessarily busboys and live-in maids. Many of them are in the professional category and they are earning as much as manufacturing workers, and often more. The first economy to follow path in the modern world was the United Kingdom. The speed at which other economies have made the transition to service-based economies has increased over time, historically, manufacturing tended to be more open to international trade and competition than services. Service providers face obstacles selling services that goods-sellers rarely face, services are intangible, making it difficult for potential customers to understand what they will receive and what value it will hold for them. Indeed, some, such as consultants and providers of investment services, since the quality of most services depends largely on the quality of the individuals providing the services, people costs are usually a high fraction of service costs. Whereas a manufacturer may use technology, simplification, and other techniques to lower the cost of goods sold, for example, how does one choose one investment adviser over another, since they are often seen to provide identical services. Charging a premium for services is usually an option only for the most established firms, who charge extra based upon brand recognition

Factory
–
Factories arose with the introduction of machinery during the Industrial Revolution when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called glorified workshops, most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, with some having rail, highway, factories may either make discrete products or some type of material continuously produced such as chemicals, pulp and paper, or refined oil products. Oil refineries have most of their equipment outdoors, discrete products may be final consumer goods, or parts and sub-assemblies which are made into final products elsewhere. Factories may be supplied parts from elsewhere or make them from raw materials, continuous production industries typically use heat or electricity to transform streams of raw materials into finished products. The term mill originally referred to the milling of grain, which usually used natural resources such as water or wind power until those were displaced by steam power in the 19th century. Because many processes like spinning and weaving, iron rolling, and paper manufacturing were originally powered by water, according to translations of Demosthenes and Herodotus, Naucratis was a, or the only, factory in the entirety of ancient Egypt. A source of 1983, states the largest factory production in ancient times was of 120 slaves within 4th century BC Athens, although The Cambridge Online Dictionary definition of factory states, a building or set of buildings where large amounts of goods are made using machines elsewhere. The wheel was invented circa 3000 BC, the spoked wheel c.2000 BC, the Iron Age began approximately 1200-1000 BC. However, other sources define machinery as a means of production, according to one text the water-mill was first made in 555 A. D. by Belisarius, although according to another they were known to Pliny the Elder and Vitruvius in the first century B. C. By the time of the 4th century A. D. mills with a capacity to grind 3 tonnes of cereal an hour, the Venice Arsenal provides one of the first examples of a factory in the modern sense of the word. Founded in 1104 in Venice, Republic of Venice, several hundred years before the Industrial Revolution, the Venice Arsenal apparently produced nearly one ship every day and, at its height, employed 16,000 people. One of the earliest factories was John Lombes water-powered silk mill at Derby, by 1746, an integrated brass mill was working at Warmley near Bristol. Raw material went in at one end, was smelted into brass and was turned into pans, pins, wire, housing was provided for workers on site. Josiah Wedgwood in Staffordshire and Matthew Boulton at his Soho Manufactory were other prominent early industrialists, the factory system began widespread use somewhat later when cotton spinning was mechanized. Richard Arkwright is the credited with inventing the prototype of the modern factory. After he patented his water frame in 1769, he established Cromford Mill, in Derbyshire, England, the factory system was a new way of organizing labour made necessary by the development of machines which were too large to house in a workers cottage. Working hours were as long as they had been for the farmer, overall, this practice essentially reduced skilled and unskilled workers to replaceable commodities

Finance
–
Finance is a field that deals with the study of investments. It includes the dynamics of assets and liabilities over time under conditions of different degrees of uncertainty, Finance can also be defined as the science of money management. Finance aims to price assets based on their level and their expected rate of return. Finance can be broken into three different sub-categories, public finance, corporate finance and personal finance. g, health and property insurance, investing and saving for retirement. Personal finance may also involve paying for a loan, or debt obligations, net worth is a persons balance sheet, calculated by adding up all assets under that persons control, minus all liabilities of the household, at one point in time. Household cash flow totals up all the sources of income within a year. From this analysis, the financial planner can determine to what degree, adequate protection, the analysis of how to protect a household from unforeseen risks. These risks can be divided into the following, liability, property, death, disability, health, some of these risks may be self-insurable, while most will require the purchase of an insurance contract. Determining how much insurance to get, at the most cost effective terms requires knowledge of the market for personal insurance, business owners, professionals, athletes and entertainers require specialized insurance professionals to adequately protect themselves. Since insurance also enjoys some tax benefits, utilizing insurance investment products may be a piece of the overall investment planning. Tax planning, typically the income tax is the single largest expense in a household, managing taxes is not a question of if you will pay taxes, but when and how much. Government gives many incentives in the form of tax deductions and credits, most modern governments use a progressive tax. Typically, as ones income grows, a marginal rate of tax must be paid. Understanding how to take advantage of the tax breaks when planning ones personal finances can make a significant impact in which it can later save you money in the long term. Investment and accumulation goals, planning how to accumulate enough money - for large purchases, major reasons to accumulate assets include, purchasing a house or car, starting a business, paying for education expenses, and saving for retirement. Achieving these goals requires projecting what they will cost, and when you need to withdraw funds that will be necessary to be able to achieve these goals, a major risk to the household in achieving their accumulation goal is the rate of price increases over time, or inflation. Using net present value calculators, the planner will suggest a combination of asset earmarking. In order to overcome the rate of inflation, the investment portfolio has to get a higher rate of return, managing these portfolio risks is most often accomplished using asset allocation, which seeks to diversify investment risk and opportunity

Code of Hammurabi
–
The Code of Hammurabi is a well-preserved Babylonian law code of ancient Mesopotamia, dating back to about 1754 BC. It is one of the oldest deciphered writings of significant length in the world, the sixth Babylonian king, Hammurabi, enacted the code, and partial copies exist on a seven and a half foot stone stele and various clay tablets. The code consists of 282 laws, with scaled punishments, adjusting an eye for an eye, nearly one-half of the code deals with matters of contract, establishing, for example, the wages to be paid to an ox driver or a surgeon. Other provisions set the terms of a transaction, establishing the liability of a builder for a house collapses, for example. A third of the code addresses issues concerning household and family such as inheritance, divorce, paternity. Only one provision appears to impose obligations on an official, this establishes that a judge who reaches an incorrect decision is to be fined and removed from the bench permanently. A few provisions address issues related to military service, the code was discovered by modern archaeologists in 1901, and its editio princeps translation published in 1902 by Jean-Vincent Scheil. This nearly complete example of the code is carved into a basalt stele in the shape of an index finger,2.25 m tall. The code is inscribed in the Akkadian language, using cuneiform script carved into the stele, Hammurabi ruled for nearly 42 years, from about 1792 to 1749 BC according to the Middle chronology. On the stone slab are 44 columns and 28 paragraphs that contained 282 laws, some of these laws follow along the rules of an eye for an eye. It had been taken as plunder by the Elamite king Shutruk-Nahhunte in the 12th century BC and was taken to Susa in Elam where it was no longer available to the Babylonian people. The Code of Hammurabi was one of several sets of laws in the ancient Near East, the code of laws was arranged in orderly groups, so that all who read the laws would know what was required of them. These codes come from similar cultures in a small geographical area. The Code of Hammurabi is the longest surviving text from the Old Babylonian period, the code has been seen as an early example of a fundamental law, regulating a government — i. e. a primitive constitution. The code is one of the earliest examples of the idea of presumption of innocence. However, its copying in subsequent generations indicates that it was used as a model of legal and judicial reasoning, the Code issues justice following the three classes of Babylonian society, property owners, freed men, and slaves. For example, if a doctor killed a patient, he would have his hands cut off. Various copies of portions of the Code of Hammurabi have been found on baked clay tablets, the Prologue of the Code of Hammurabi is on such a tablet, also at the Louvre

Insurance
–
Insurance is a means of protection from financial loss. It is a form of risk management primarily used to hedge against the risk of a contingent, an entity which provides insurance is known as an insurer, insurance company, or insurance carrier. A person or entity who buys insurance is known as an insured or policyholder, the insured receives a contract, called the insurance policy, which details the conditions and circumstances under which the insured will be financially compensated. The amount of money charged by the insurer to the insured for the coverage set forth in the policy is called the premium. If the insured experiences a loss which is covered by the insurance policy. Methods for transferring or distributing risk were practiced by Chinese and Babylonian traders as long ago as the 3rd and 2nd millennia BC, Chinese merchants travelling treacherous river rapids would redistribute their wares across many vessels to limit the loss due to any single vessels capsizing. The Babylonians developed a system which was recorded in the famous Code of Hammurabi, c.1750 BC, and practiced by early Mediterranean sailing merchants. If a merchant received a loan to fund his shipment, he would pay the lender an additional sum in exchange for the guarantee to cancel the loan should the shipment be stolen. At some point in the 1st millennium BC, the inhabitants of Rhodes created the general average and this allowed groups of merchants to pay to insure their goods being shipped together. The collected premiums would be used to any merchant whose goods were jettisoned during transport. Separate insurance contracts were invented in Genoa in the 14th century, the first known insurance contract dates from Genoa in 1347, and in the next century maritime insurance developed widely and premiums were intuitively varied with risks. These new insurance contracts allowed insurance to be separated from investment, Insurance became far more sophisticated in Enlightenment era Europe, and specialized varieties developed. Property insurance as we know it today can be traced to the Great Fire of London, initially,5,000 homes were insured by his Insurance Office. At the same time, the first insurance schemes for the underwriting of business ventures became available, by the end of the seventeenth century, Londons growing importance as a center for trade was increasing demand for marine insurance. These informal beginnings led to the establishment of the insurance market Lloyds of London and several related shipping, the first life insurance policies were taken out in the early 18th century. The first company to offer life insurance was the Amicable Society for a Perpetual Assurance Office, founded in London in 1706 by William Talbot, edward Rowe Mores established the Society for Equitable Assurances on Lives and Survivorship in 1762. In the late 19th century, accident insurance began to become available and this operated much like modern disability insurance. The first company to offer accident insurance was the Railway Passengers Assurance Company, by the late 19th century, governments began to initiate national insurance programs against sickness and old age

Statistics
–
Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data. In applying statistics to, e. g. a scientific, industrial, or social problem, populations can be diverse topics such as all people living in a country or every atom composing a crystal. Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys, statistician Sir Arthur Lyon Bowley defines statistics as Numerical statements of facts in any department of inquiry placed in relation to each other. When census data cannot be collected, statisticians collect data by developing specific experiment designs, representative sampling assures that inferences and conclusions can safely extend from the sample to the population as a whole. In contrast, an observational study does not involve experimental manipulation, inferences on mathematical statistics are made under the framework of probability theory, which deals with the analysis of random phenomena. A standard statistical procedure involves the test of the relationship between two data sets, or a data set and a synthetic data drawn from idealized model. A hypothesis is proposed for the relationship between the two data sets, and this is compared as an alternative to an idealized null hypothesis of no relationship between two data sets. Rejecting or disproving the hypothesis is done using statistical tests that quantify the sense in which the null can be proven false. Working from a hypothesis, two basic forms of error are recognized, Type I errors and Type II errors. Multiple problems have come to be associated with this framework, ranging from obtaining a sufficient sample size to specifying an adequate null hypothesis, measurement processes that generate statistical data are also subject to error. Many of these errors are classified as random or systematic, the presence of missing data or censoring may result in biased estimates and specific techniques have been developed to address these problems. Statistics continues to be an area of research, for example on the problem of how to analyze Big data. Statistics is a body of science that pertains to the collection, analysis, interpretation or explanation. Some consider statistics to be a mathematical science rather than a branch of mathematics. While many scientific investigations make use of data, statistics is concerned with the use of data in the context of uncertainty, mathematical techniques used for this include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure-theoretic probability theory. In applying statistics to a problem, it is practice to start with a population or process to be studied. Populations can be diverse topics such as all living in a country or every atom composing a crystal. Ideally, statisticians compile data about the entire population and this may be organized by governmental statistical institutes

Wall Street Crash of 1929
–
The crash, which followed the London Stock Exchanges crash of September, signaled the beginning of the 12-year Great Depression that affected all Western industrialized countries. The Roaring Twenties, the decade that followed World War I and led to the crash, was a time of wealth, while the American cities prospered, the overproduction of agricultural produce created widespread financial despair among American farmers throughout the decade. This would later be blamed as one of the key factors that led to the 1929 stock market crash, despite the dangers of speculation, many believed that the stock market would continue to rise forever. On March 25,1929, after the Federal Reserve warned of excessive speculation, two days later, banker Charles E. Mitchell announced his company the National City Bank would provide $25 million in credit to stop the markets slide. Mitchells move brought a halt to the financial crisis and call money declined from 20 to 8 percent. Despite all these economic trouble signs and the breaks in March and May 1929, stocks resumed their advance in June. The market had been on a run that saw the Dow Jones Industrial Average increase in value tenfold. Shortly before the crash, economist Irving Fisher famously proclaimed, Stock prices have reached what looks like a high plateau. The optimism and financial gains of the bull market were shaken after a well publicized early September prediction from financial expert Roger Babson that a crash was coming. The initial September decline was thus called the Babson Break in the press and this was the start of the Great Crash, although until the severe phase of the crash in October, many investors regarded the September Babson Break as a healthy correction and buying opportunity. On September 20, the London Stock Exchange crashed when top British investor Clarence Hatry and many of his associates were jailed for fraud, the London crash greatly weakened the optimism of American investment in markets overseas. In the days leading up to the crash, the market was severely unstable, periods of selling and high volumes were interspersed with brief periods of rising prices and recovery. On October 24, the market lost 11 percent of its value at the bell on very heavy trading. Several leading Wall Street bankers met to find a solution to the panic and chaos on the trading floor. The meeting included Thomas W. Lamont, acting head of Morgan Bank, Albert Wiggin, head of the Chase National Bank and they chose Richard Whitney, vice president of the Exchange, to act on their behalf. With the bankers financial resources behind him, Whitney placed a bid to purchase a block of shares in U. S. Steel at a price well above the current market. As traders watched, Whitney then placed similar bids on other blue chip stocks and this tactic was similar to one that ended the Panic of 1907. It succeeded in halting the slide, the Dow Jones Industrial Average recovered, closing with it down only 6.38 points for the day

Warren Buffett
–
Warren Edward Buffett is an American business magnate, investor, and philanthropist. He is considered by some to be one of the most successful investors in the world and he attended New York Institute of Finance to specialize his economics background and soon after began various business partnerships, including one with Graham. After meeting Charlie Munger, Buffett created the Buffett Partnership and his firm would eventually acquire a textile manufacturing firm called Berkshire Hathaway and assume its name to create a diversified holding company. He is noted for his adherence to value investing and for his personal frugality despite his immense wealth, Buffett is a notable philanthropist, having pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Bill & Melinda Gates Foundation. Buffett was born in 1930 in Omaha, Nebraska and he was the second of three children and the only son of Leila and Congressman Howard Buffett, Buffett began his education at Rose Hill Elementary School. In 1942, his father was elected to the first of four terms in the United States Congress, after finishing high school and finding success with his side entrepreneurial and investment ventures, Buffett wanted to skip college to go directly into business, but was overruled by his father. Buffett displayed an interest in business and investing at a young age, much of Buffetts early childhood years were enlivened with entrepreneurial ventures. One of his first business ventures, Buffett sold chewing gum, Coca-Cola bottles and he worked in his grandfathers grocery store. While still in school, he made money delivering newspapers, selling golf balls and stamps. On his first income tax return in 1944, Buffett took a $35 deduction for the use of his bicycle, in 1945, as a high school sophomore, Buffett and a friend spent $25 to purchase a used pinball machine, which they placed in the local barber shop. Within months, they owned several machines in three different barber shops across Omaha, the business was sold later in the year for $1,200 to a war veteran. Buffetts interest in the market and investing dated to schoolboy days he spent in the customers lounge of a regional stock brokerage near his fathers own brokerage office. On a trip to New York City at age ten, he made a point to visit the New York Stock Exchange, at 11, he bought three shares of Cities Service Preferred for himself, and three for his sister Doris Buffett. At the age of 15, Warren made more than $175 monthly delivering Washington Post newspapers, in high school, he invested in a business owned by his father and bought a 40-acre farm worked by a tenant farmer. He bought the land when he was 14 years old with $1,200 of his savings, by the time he finished college, Buffett had accumulated $9,800 in savings. In 1947, Buffett entered the Wharton School of the University of Pennsylvania and he would have preferred to focus on his business ventures, however, he enrolled due to pressure from his father.

Benjamin Graham
–
Benjamin Graham was a British-born American investor, economist, and professor. He is widely known as the father of value investing, and has two of the founding texts in neoclassical investing, Security Analysis with David Dodd, and The Intelligent Investor. After graduating from Columbia University at age 20, he moved to New York City to work on Wall Street eventually founding the Graham-Newman Partnership. His work in economics and investing has led to a modern wave of value investing within mutual funds, hedge funds, diversified holding companies. Ruane, Irving Kahn and Walter J. Schloss, and others and his thoughts on investing have influenced the likes of Seth Klarman and Bill Ackman. He was born Benjamin Grossbaum in London, England, to Jewish parents and he moved to New York City with his family when he was one year old. After the death of his father and experiencing poverty, he became a student, graduating from Columbia University, as salutatorian of his class. He received an invitation for employment as an instructor in English, mathematics, and philosophy, early in his professional life, Graham made a name for himself with The Northern Pipeline Affair, involving John D. Rockefeller. His first book, Security Analysis, with David Dodd, was published in 1934, Security Analysis and The Intelligent Investor, published in 1949, are his two most widely acclaimed books. Warren Buffett describes The Intelligent Investor as the best book about investing ever written, Graham exhorted the stock market participant to first draw a fundamental distinction between investment and speculation. In Security Analysis, he proposed a definition of investment that was distinguished from what he deemed speculation. It read, An investment operation is one which, upon analysis, promises safety of principal. Operations not meeting these requirements are speculative, Graham wrote that the owner of equity stocks should regard them first and foremost as conferring part ownership of a business. Graham distinguished between the passive and the active investor, the passive investor, often referred to as a defensive investor, invests cautiously, looks for value stocks, and buys for the long term. The active investor, on the hand, is one who has more time, interest. Graham recommended that investors spend time and effort to analyze the state of companies. When a company is available on the market at a price which is at a discount to its value, a margin of safety exists. Graham wrote that investment is most intelligent when it is most businesslike, by that he meant that the stock investor is neither right nor wrong because others agreed or disagreed with him, he is right because his facts and analysis are right

Interest
–
Interest is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum. It is distinct from a fee which the borrower may pay the lender or some third party, in the case of savings, the customer is the lender, and the bank plays the role of the borrower. Interest differs from profit, in that interest is received by a lender, whereas profit is received by the owner of an asset, the rate of interest is equal to the interest amount paid or received over a particular period divided by the principal sum borrowed or lent. Compound interest means that interest is earned on prior interest in addition to the principal, due to compounding, the total amount of debt grows exponentially, and its mathematical study led to the discovery of the number e. In practice, interest is most often calculated on a daily, monthly, or yearly basis, according to historian Paul Johnson, the lending of food money was commonplace in Middle Eastern civilizations as early as 5000 BC. The argument that acquired seeds and animals could reproduce themselves was used to justify interest, early Muslims called this riba, translated today as the charging of interest. The First Council of Nicaea, in 325, forbade clergy from engaging in usury which was defined as lending on interest above 1 percent per month, ninth century ecumenical councils applied this regulation to the laity. Catholic Church opposition to interest hardened in the era of scholastics, in the medieval economy, loans were entirely a consequence of necessity and, under those conditions, it was considered morally reproachable to charge interest. For the same reason, interest has often been looked down upon in Islamic civilization, medieval jurists developed several financial instruments to encourage responsible lending and circumvent prohibitions on usury, such as the Contractum trinius. In the Renaissance era, greater mobility of people facilitated an increase in commerce, given that borrowed money was no longer strictly for consumption but for production as well, interest was no longer viewed in the same manner. The first attempt to control interest rates through manipulation of the supply was made by the Banque de France in 1847. The latter half of the 20th century saw the rise of interest-free Islamic banking and finance, a movement that applies Islamic law to financial institutions, some countries, including Iran, Sudan, and Pakistan, have taken steps to eradicate interest from their financial systems. All financial transactions must be asset-backed and it does not charge any interest or fee for the service of lending, in economics, the rate of interest is the price of credit, and it plays the role of the cost of capital. Over centuries, various schools of thought have developed explanations of interest and interest rates, the School of Salamanca justified paying interest in terms of the benefit to the borrower, and interest received by the lender in terms of a premium for the risk of default. In the sixteenth century, Martín de Azpilcueta applied a time preference argument, accordingly, interest is compensation for the time the lender forgoes the benefit of spending the money. On the question of why interest rates are normally greater than zero, in 1770, French economist Anne-Robert-Jacques Turgot, for the land value to remain positive and finite keeps the interest rate above zero. Adam Smith, Carl Menger, and Frédéric Bastiat also propounded theories of interest rates, in the 1930s, Wicksells approach was refined by Bertil Ohlin and Dennis Robertson and became known as the loanable funds theory. Other notable interest rate theories of the period are those of Irving Fisher, simple interest is calculated only on the principal amount, or on that portion of the principal amount that remains
