Comparative Statics Analysis Equilibrium analysis provides us with a means of determining the values of endogenous variables when a given set of external conditions exist. As is often the case, we are interested in how those values change when the external conditions vary. Since we are not able to hold other things constant for very long, we need a way of comparing different equilibrium states that are associated with different sets of values for parameters and exogenous variables.

Comparative statics analysis is a means of making such comparisons. In comparative statics we ignore the adjustment process entirely.

Our focus is on comparing the initial prechange equilibrium values for the endogenous variables with the final postchange equilibrium values. The comparative statics approach is essentially one of finding a rate of change; specifically, the rate of change of the value of the endogenous variable with respect to the change in the particular parameter or exogenous variable.

For this reason, the mathematical concept of the derivative takes on a special significance in comparative statics analysis. This notation emphasizes that a derivative measures the rate of change.

It is a measure of the slope of a function at any point and a way to get at the concept of the margin. This is important in economics since marginal analysis is central to the theory of choice behavior.

All economic decisions are made at the margin. Seldom are we faced with "all-or-none" situations. The process of reaching a preferred position involves making tradeoffs; i.

Approaching the static-equilibrium problem from the perspective of the rate of change, we can illustrate the difference equation and how we use calculus to solve equilibrium problems.

To solve the difference equation, first write each equation in terms of the respective prices. Before going into comparative statics models, we must first familiarize ourselves with some of the rules of differentiation. The derivative of a constant k is always zero.Economics is the study of _____.

• Economics is the science of scarcity. • Scarcity is the condition in which our wants are greater than our limited resources. • Since we are unable to have everything we desire, we must make choices on how we will use our resources.
