Beyond the Ceteris Paribus Assumption: Modeling Demand and Supply Assuming Omnia Mobilis
Date Written: December 30, 2009
Abstract
This paper is concerned with the application of multi-dimensional graphs in visualizing and modeling total change in a dependent variable in response to changes in any or all of the (many) independent variables affecting it. Previous literature has used the ceteris paribus assumption to obtain total change as a cumulative effect of the effect of the individual parts. The multi-dimensional graph applied to demand and supply shows that under the Omnia Mobilis (everything is moving) assumption, the quantity sold in the market is a joint function of all the independent variables that affect supply and demand.
