The Business and economics Portal
In the social sciences
is the study of human choice
behavior and the methodology used to make associated investment and production decisions; in particular, though not limited to, how those choices and decisions determine the allocation of scarce resources and their effect on production
, and consumption
. The word "economics" is from the Greek
], meaning "family, household, estate", and νόμος [nomos
], or "custom, law", and hence literally means "household management" or "management of the state". An economist
is a person using economic concepts and data in the course of employment, or someone who has earned a university degree
in the subject. Economics undergraduate courses always cover at least the two main branches:
- Microeconomics studies the behavior of individual households and firms in making decisions on the allocation of limited resources. Microeconomics applies to markets where goods or services are bought and sold. It examines how decisions and behaviors affect the supply and demand for goods and services, which determines prices, and how prices, in turn, determine the quantity supplied and quantity demanded of goods and services.
- Macroeconomics deals with the performance, structure, behavior, and decision-making of an economy as a whole, rather than individual markets. This includes national, regional, and global economies.
However, there are also others sub-field of economics (see JEL classification codes).
In economics, economic systems is the study and analysis of organizing production, distribution, consumption and investment and the study of optimal resource allocation and institutional design. Traditionally the study of economic systems was based on a dichotomy between market economies and planned economies, but contemporary studies compare and contrast a number of different variables, such as ownership structure (Public, Private or Collective), economic coordination (planning, markets or mixed), management structure (Hierarchy versus adhocracy), the incentive system, and the level of centralization in decision-making. A business, also known as an enterprise or a firm, is an organization involved in the trade of goods, services, or both to consumers. Businesses are prevalent in capitalist economies, where most of them are privately owned and provide goods and services to customers in exchange of other goods, services, or money. Businesses may also be not-for-profit or state-owned. Management in business and organizations is the function that coordinates the efforts of people to accomplish goals and objectives using available resources efficiently and effectively. Management comprises planning, organizing, staffing, leading or directing, and controlling an organization or initiative to accomplish a goal. Management is also an academic discipline, and is traditionally taught at business schools. An economy can be analyzed in terms of its economic sectors, the classic breakdown being into primary, secondary and tertiary. Economic policy refers to the actions that governments take in the economic field. It covers the systems for setting interest rates and government budget as well as the labor market regulations, national ownership, trade policy, monetary policy, fiscal policy, regulatory policy, anti-trust policy and industrial policy. In economics, sustainable development refers to development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
The slate industry in Wales began during the Roman period when slate was used to roof the fort at Segontium, modern Caernarfon. The slate industry grew slowly until the early 18th century, from when it expanded rapidly and reached its peak output in the late 19th century, at which time the most important slate producing areas were in north-west Wales. These included the Penrhyn Quarry near Bethesda, the Dinorwig Quarry near Llanberis, the Nantlle Valley quarries and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. The Great Depression and the Second World War led to the closure of many smaller quarries, and competition from other roofing materials, particularly tiles, resulted in the closure of most of the larger quarries in the 1960s and 1970s. Slate production continues on a much reduced scale.

The 1933 double eagle is a United States 20-dollar gold coin. Although 445,500 specimens of this Saint-Gaudens double eagle were minted in 1933 none were ever officially circulated and all but two were melted down. Supposedly, 20 found their way into the hands of collectors, but 19 of these were subsequently seized or voluntarily turned in to the Secret Service, who destroyed nine of them, making this one of the world's rarest coins. Five are still missing out of the 20.
Jesus Cleanses the Temple
"15 And they came to Jerusalem. And he entered the temple and began to drive out those who sold and those who bought in the temple, and he overturned the tables of the money-changers and the seats of those who sold pigeons. 16 And he would not allow anyone to carry anything through the temple. 17 And he was teaching them and saying to them, “Is it not written, ‘My house shall be called a house of prayer for all the nations’? But you have made it a den of robbers.” 18 And the chief priests and the scribes heard it and were seeking a way to destroy him, for they feared him, because all the crowd was astonished at his teaching. 19 And when evening came they went out of the city."
