Testing Separability In A Generalized Ordinary Differential Demand System: The Case Of Nigerian Demand For Meat


  • Ogunyinka, Ebenezer
  • Marsh, Thomas L.


This study investigates consumer demand for meat products in Nigeria and tests if any of the meat products are separable from one another. Estimating a generalized nested demand system, the Rotterdam model was selected using an adjusted likelihood ratio test. Results indicate that mutton and pork are more elastic than beef and poultry. Only pork was found to be separable from other meat types.
