LEGAL TYPES: The three primary types of legal firm organizations are: (1) proprietorship, (2) partnership, and (3) corporation. One primary difference between these three legal types are number of owners -- proprietorship has one, partnership has two or more (but usually a small number), and corporation can have anywhere from one or to millions. A second difference is the liability of the owners -- proprietorship and partnership owners have unlimited liability and corporation owners have limited liability. Three newer firm types include (1) limited partnership, (2) S corporation, and (3) limited liability company. Each of these three are hybrids, with characteristics of proprietorship, partnership, corporation.

                           VARIABLES: Quantities, usually represented as symbols, that can take on one of a set of values. A variable is "variable" because its value can "vary." A primary goal of economic analysis is to determine the specific value that a variable takes on under specific circumstances. Variables are allowed to vary, to take on different values. Models combine variables in a systematic manner (based on the underlying theory). The basic purpose of a model is then to identify different, specific values for the variables.For example, the two key variables in a market model are price and quantity. Analysis of the market model then identifies specific values for price and quantity. Endogenous and ExogenousIn the analysis of a model, variables generally take one of two forms -- endogenous (or dependent) and exogenous (or independent).- Endogenous: The values of endogenous or dependent variables are identified within the workings of the model. For example, price and quantity are endogenous variables for the market model. Endogenous variables are, in essence, the "output" of the model. Their identification is what the model is all about.
- Exogenous: The values of exogenous or independent variables are established outside the workings of the model. For example, income or the cost of a productive resource are common exogenous variables for the market model. Exogenous variables are the "input" of the model. They are pre-determined or "given" to the model.
InteractionThe interaction among endogenous and exogenous variables is key to the analysis of a model. Endogenous variables in a model are identified based on the pre-determined values of exogenous variables. Should these exogenous variables take on different values, then the endogenous variables also generally take on different values.For example, endogenous price and quantity variables identified in a market model are, in part, based on the exogenous variable--the income of the buyers. Should buyers have more or less income, then their demand is likely to change and so too are price and quantity.

Today, you are likely to spend a great deal of time going from convenience store to convenience store hoping to buy either arch supports for your shoes or an AC adapter that works with your MPG player. Be on the lookout for empty parking spaces that appear to be near the entrance to a store.
