The time required to start a business is the number of calendar days needed to complete the procedures to legally operate a business. This chart is from 2017 statistics.

Business is the practice of making one's living or making money by producing or buying and selling products (such as goods and services). It is also "any activity or enterprise entered into for profit."

A business entity is not necessarily separate from the owner and the creditors can hold the owner liable for debts the business has acquired. The taxation system for businesses is different from that of the corporates. A business structure does not allow for corporate tax rates. The proprietor is personally taxed on all income from the business.

A distinction is made in law and public offices between the term business and a company such as a corporation or cooperative. Colloquially, the terms are used interchangeably. (Full article...)

Economics (/ˌɛkəˈnɒmɪks, ˌkə-/) is a social science that studies the production, distribution, and consumption of goods and services.

Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyses what is viewed as basic elements within economies, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and investment expenditure interact, and factors affecting it: factors of production, such as labour, capital, land, and enterprise, inflation, economic growth, and public policies that have impact on these elements. It also seeks to analyse and describe the global economy. (Full article...)

Microsoft Corporation, or often just MS, is an American multinational computer technology corporation with 79,000 employees in 102 countries and global annual revenue of US $51.12 billion as of 2007. It develops, manufactures, licenses and supports a wide range of software products for computing devices. Headquartered in Redmond, Washington, USA, its best selling products are the Microsoft Windows operating system and the Microsoft Office suite of productivity software. These products have prominent positions in the desktop computer market, with market share estimates as high as 90% or more as of 2003 for Microsoft Office and 2006 for Microsoft Windows, in line with Bill Gates's vision "to get a workstation running our software onto every desk and eventually in every home".

Founded to develop and sell BASIC interpreters for the Altair 8800, Microsoft rose to dominate the home computer operating system market with MS-DOS in the mid-1980s. The company released an initial public offering (IPO) in the stock market, which, due to the ensuing rise of the stock price, has made four billionaires and an estimated 12,000 millionaires from Microsoft employees. Throughout its history the company has been the target of criticism for various reasons, including monopolistic business practices—both the U.S. Justice Department and the European Commission, among others, brought Microsoft to court for antitrust violations and software bundling.

Microsoft has footholds in other markets besides operating systems and office suites, with assets such as the MSNBC cable television network, the MSN Internet portal, and the Microsoft Encarta multimedia encyclopedia. The company also markets both computer hardware products such as the Microsoft mouse and home entertainment products such as the Xbox, Xbox 360, Zune and MSN TV. Known for what is generally described as a developer-centric business culture, Microsoft has historically given customer support over Usenet newsgroups and the World Wide Web, and awards Microsoft MVP status to volunteers who are deemed helpful in assisting the company's customers.

A supermarket, a large form of the traditional grocery store, is a self-service shop offering a wide variety of food and household products, organized into aisles. It is larger in size and has a wider selection than a traditional grocery store, but is smaller and more limited in the range of merchandise than a hypermarket or big-box market.

Selected quote

"This essay has been devoted to an exposition and elaboration of a single syllogism: given that the structure of an econometric model consist of optimal decision rules of economic agents, and that optimal decision rules vary systematically with changes in the structure of series relevant to the decision maker, it follows that any change in policy will systematically alter the structure of econometric models.

For the question of short-term forecasting, or tracking ability of econometric models, we have seen that this conclusion is of only occasional significance. For issues involving policy evaluation, in contrast, it is fundamental; for it implies that comparisons of the effects of alternative policy rules using current macro-econometric models are invalid regardless of the performance of these models over the sample period or in ex-ante short-term forecasting."

Robert Lucas, Econometric Policy Evaluation: A Critique, 1976
