Economic model Representations of the real world, which omit all variables that are not relevant to the specific issue the model was designed to address. Marginal analysis The study of the consequences of small changes in a variable. Marginal utility The change in total utility derived from a one unit increase in consumption. Production function The functional relationship that indicates how inputs are transformed into outputs in the most efficient way. Economic analysis Economic models are representations of the real world, which omit all variables that are not relevant to the specific issue the model was designed to address. Models represent the relationships between different variables. They can be used to make predictions in the form of 'if... then ...' statements. Models, by definition, are able to make predictions about the effect of a change in one particular variable, while all other variables remain unchanged. The assumption that all other variables remain unchanged is referred to as the ceteris paribus assumption
