Gini coefficient

Gini coefficient
Gini coefficient of national income distribution around the world. This is based on 1989 to 2009 data, estimated by the CIA. Some are pre-tax and transfer, others post-tax income. The Gini coefficient (also known as the Gini index or Gini ratio) (/dʒini/) is a measure of statistical dispersion intended to represent the income distribution of a nation's residents. The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income). There are some issues in interpreting a Gini coefficient. Definition[edit] Graphical representation of the Gini coefficient The graph shows that the Gini coefficient is equal to the area marked A divided by the sum of the areas marked A and B. that is, Gini = A / (A + B). The Gini coefficient is usually defined mathematically based on the Lorenz curve, which plots the proportion of the total income of the population (y axis) that is cumulatively earned by the bottom x% of the population (see diagram). where and

Global governance Global governance or world governance is a social movement toward political integration of transnational actors aimed at solving problems that affect more than one state or region when there is no power of enforcing compliance. The modern question of world governance exists in the context of globalization. In response to the acceleration of interdependence on a worldwide scale, both between human societies and between humankind and the biosphere, the term "world governance" may also be used to designate laws, rules, or regulations intended for a global scale. Definition[edit] In a simple and broad-based definition of world governance, the term is used to designate all regulations intended for organization and centralization of human societies on a global scale.[1] Traditionally, government has been associated with "governing," or with political authority, institutions, and, ultimately, control.

Listen, Little Man! What Does Your Body Language Say About You? How To Read Signs and Recognize Gestures - Jinxi Boo - Jinxi Boo Art by LaetitziaAs we all know, communication is essential in society. Advancements in technology have transformed the way that we correspond with others in the modern world. Because of the constant buzz in our technological world, it's easy to forget how important communicating face-to-face is. Body language is truly a language of its own. 10% from what the person actually says40% from the tone and speed of voice50% is from their body language. Lowering one's head can signal a lack of confidence. Pushing back one's shoulders can demonstrate power and courageOpen arms means one is comfortable with being approached and willing to talk/communicate The lowering of the eyes can convey fear, guilt or submissionLowered eyebrows and squinted eyes illustrate an attempt at understanding what is being said or going onA lack of confidence or apprehensiveness can be displayed when you don't look another person in the eyesOne tends to blink more often if nervous or trying to evaluate someone else

Globalization Globalisation (or globalization) is the process of international integration arising from the interchange of world views, products, ideas, and other aspects of culture.[1][2] Advances in transportation and telecommunications infrastructure, including the rise of the telegraph and its posterity the Internet, are major factors in globalization, generating further interdependence of economic and cultural activities.[3] Though scholars place the origins of globalization in modern times, others trace its history long before the European age of discovery and voyages to the New World. Some even trace the origins to the third millennium BCE.[4][5] In the late 19th century and early 20th century, the connectedness of the world's economies and cultures grew very quickly. Overview[edit] Humans have interacted over long distances for thousands of years. Airline personnel from the "Jet set" age, circa 1960. Etymology and usage[edit] Sociologists Martin Albrow and Elizabeth King define globalization as:

Stock trades to exploit speed of light, says researcher 23 March 2011Last updated at 03:20 By Jason Palmer Science and technology reporter, BBC News, Dallas Optimal high-frequency trading locations (blue) exist for pairs of major financial exchanges (red) Financial institutions may soon change what they trade or where they do their trading because of the speed of light. "High-frequency trading" carried out by computers often depends on differing prices of a financial instrument in two geographically-separated markets. Exactly how far the signals have to go can make a difference in such trades. Alexander Wissner-Gross told the American Physical Society meeting that financial institutions are looking at ways to exploit the light-speed trick. Dr Wissner-Gross, of Harvard University, said that the latencies - essentially, the time delay for a signal to wing its way from one global financial centre to another - advantaged some locations for some trades and different locations for others.

Why powerful people -- many of whom take a moral high ground -- don't practice what they preach 2009 may well be remembered for its scandal-ridden headlines, from admissions of extramarital affairs by governors and senators, to corporate executives flying private jets while cutting employee benefits, and most recently, to a mysterious early morning car crash in Florida. The past year has been marked by a series of moral transgressions by powerful figures in political, business and celebrity circles. New research from the Kellogg School of Management at Northwestern University explores why powerful people - many of whom take a moral high ground - don't practice what they preach. Researchers sought to determine whether power inspires hypocrisy, the tendency to hold high standards for others while performing morally suspect behaviors oneself. The research finds that power makes people stricter in moral judgment of others - while being less strict of their own behavior. The research was conducted by Joris Lammers and Diederik A.

Externality In economics, an externality is the cost or benefit that affects a party who did not choose to incur that cost or benefit.[1] Implications[edit] External costs and benefits Voluntary exchange is considered mutually beneficial to both parties involved, because buyers or sellers would not trade if either thought it detrimental to themselves. However, a transaction can cause additional effects on third parties. From the perspective of those affected, these effects may be negative (pollution from a factory), or positive (honey bees kept for honey that also pollinate neighboring crops). A voluntary exchange may reduce societal welfare if external costs exist. On the other hand, a positive externality would increase the utility of third parties at no cost to them. There are a number of potential means of improving overall social utility when externalities are involved. Examples[edit] Negative[edit] Barry Commoner commented on the costs of externalities: Positive[edit] Positional[edit]

Jevons paradox The Jevons paradox has been used to argue that energy conservation may be futile, as increased efficiency may increase fuel use. Nevertheless, increased efficiency can improve material living standards. Further, fuel use declines if increased efficiency is coupled with a green tax or other conservation policies that keep the cost of use the same (or higher).[3] As the Jevons paradox applies only to technological improvements that increase fuel efficiency, policies that impose conservation standards and increase costs do not display the paradox. History[edit] The Jevons paradox was first described by the English economist William Stanley Jevons in his 1865 book The Coal Question. Jevons observed that England's consumption of coal soared after James Watt introduced his coal-fired steam engine, which greatly improved the efficiency of Thomas Newcomen's earlier design.

Are you in career transition? Been laid off? Want a new job? | VocationVacations® Gross domestic product Gross domestic product (GDP) is defined by the Organisation for Economic Co-operation and Development (OECD) as "an aggregate measure of production equal to the sum of the gross values added of all resident, institutional units engaged in production (plus any taxes, and minus any subsidies, on products not included in the value of their outputs)."[2] GDP estimates are commonly used to measure the economic performance of a whole country or region, but can also measure the relative contribution of an industry sector. This is possible because GDP is a measure of 'value added' rather than sales; it adds each firm's value added (the value of its output minus the value of goods that are used up in producing it). The more familiar use of GDP estimates is to calculate the growth of the economy from year to year (and recently from quarter to quarter). History[edit] The history of the concept of GDP should be distinguished from the history of changes in ways of estimating it. Determining GDP[edit]
