G-8: The common abbreviation for the Group of Eight, which includes the seven of the most advanced and industrialized nations of the world known as the G-7--the United States, Britain, France, Italy, Canada, Germany, and Japan--plus Russia. That is, the G-8 is the G-7 plus Russia, which effectively replaced the G-7 in 1998. They meet regularly to coordinate fiscal and monetary policies. Their actions are based on the proposition that our global economy and the individual countries are better off through cooperation than conflict.

The process of investigating economic phenomena in a systematic manner. In one sense, this is the heart and soul of the economic discipline. While economists spend an ample time identifying economic concepts, the end result of this discovery process is usually aimed at combining these concepts in such a way as to evaluate or analyze alternative consequences.
For example, economists seek to understand the notions of demand and supply. But this is not the end result of their analytical quest. They are more interested in analyzing how a change in buyers' income, as a demand determinant, affects the demand for a good like gasoline and subsequently its price. Or how technological improvements, as a supply determinant, affects the supply of a good like computers and subsequently the quantity sold.

One important aspect of economic analysis is that it is typically performed "at the margin," meaning that economists are usually more concerned with small, incremental changes than with overall totals. For example, economists are more interested in how many additional computers are sold because of the technological advance than in the total sales of computers.

The reason for this "marginal" obsession is that consumers, producers, and other economic decision-makers usually make choices "at the margin." Consumers decide whether or not to buy another hot fudge sundae today (having eaten dozens this year). They do not decide in January how many to purchase for the entire year. They decide each hot fudge sundae purchase one at a time. And so it goes for many economic decisions.
