Economics

Economics is the social science that studies the production, distribution, and consumption of goods and services. The term economics comes from the Greek for oikos (house) and nomos (custom or law), hence “rules of the house (hold).”

A definition that captures much of modern economics is that of Lionel Robbins in a 1932 essay: “the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.” Scarcity means that available resources are insufficient to satisfy all wants and needs. Absent scarcity and alternative uses of available resources, there is no economic problem. The subject thus defined involves the study of choices as they are affected by incentives and resources.

Areas of economics may be divided or classified into various types, including:

· microeconomics and macroeconomics

· positive economics (“what is”) and normative economics (“what ought to be”)

· mainstream economics and heterodox economics

· fields and broader categories within economics.

One of the uses of economics is to explain how economies, as economic systems, work and what the relations are between economic players (agents) in the larger society. Methods of economic analysis have been increasingly applied to fields that involve people (officials included) making choices in a social context, such a crime, education, the family, health, law, politics, religion, social institutions, and war.

Costs

Fixed Costs – Also referred to as overhead costs, these represent costs the marketing organization incurs that are not affected by level of production or sales. For example, for a manufacturer of writing instruments that has just built a new production facility, whether they produce one pen or one million they will still need to pay the monthly mortgage for the building. From the marketing site, fixed costs may also exist in the form of expenditure for fielding a sales force, carrying out an advertising campaign and paying a service to host the company’s website. These costs are fixed because there is a level of commitment to spending that is largely not affected by production or sales levels.

Variable Costs – These costs are directly associated with the production and sales of products and, consequently, change has the level of production or sales changes. Typically variable costs are evaluated on a per-unit basis since the cost is directly associated with individual terms. Most variable costs involve costs of terms that are either components of the product (e.g. parts, packaging) or are directly associated with creating the product ((e.g. electricity to run an assembly line). However, there are also marketing variable costs such as coupons, which are likely to cost the company more as sales increase (i.e., customers using the coupon). Variable costs, especially, for tangible products, tend to decline as more units are produced. This is due to the producing company’s ability to purchase product components for lower prices since component suppliers often provide discounted pricing for large quantity purchases.
