ANALYSIS OF A GRAVITY DEMAND MODEL

A GRAVITY MODEL IS DESCRIBED FOR ESTIMATING RETAIL EXPENDITURE AT SHOPPING CENTERS. THE GRAVITY MODEL MAKES ASSUMPTIONS ABOUT THE RELATIVE ATTRACTIVENESS OF SHOPPING CENTERS IN A GIVEN REGION WITH A GIVEN TOTAL LEVEL OF EXPENDITURE. THE MODEL SUGGESTS THAT AN EQUILIBRIUM SOLUTION EXISTS, SUCH THAT WHEN IT IS REACHED THERE IS NO TENDENCY FOR THE SALES AT ANY CENTER TO GROW OR TO DECLINE. THE NATURE OF THIS SOLUTION IS ANALYZED. IT IS SHOWN THAT IN SOME CASES THE MODEL WILL INDICATE THAT THE VALUE FOR THE EQUILIBRIUM SOLUTION FOR SALES AT A CENTER IS ZERO. FURTHERMORE, IT IS SHOWN THAT, EXCEPT UNDER SPECIAL CONDITIONS, THIS EQUILIBRIUM SOLUTION IS UNIQUE. AN EXAMPLE WITH TWO SHOPPING CENTERS AND TWO EXPENDITURE ZONES IS FULLY ANALYZED AND GRAPHS AND MAPS ARE DRAWN TO ILLUSTRATE THE SOLUTIONS OBTAINED. /AUTHOR/
