ANALYSIS OF MEAT DEMAND IN MALAYSIA: MODEL CHOICE BETWEEN ROTTERDAM AND AIDS

Maria Divina S. Paraguas et al.

Abstract


Aggregated time series data for differentiated meat products namely,
beef, pork, poultry and mutton were used to estimate and analyze
Malaysian market demand for meats. The study aimed to select the
most appropriate demand model between the equally popular
Rotterdam model and tlre first difference Linear Approximate Almost
Ideal Demand System (LAIAIDS) model by using a non-nested test-
Both models were accepted, but further diagnostic tests revealed that
the first difference LA/AIDS represents more appropriately the
Malaysian market demand for meat than the Rotterdam model. Also,
the elasticities from the first difference LAIAIDS were found to be
more reliable than the Rotterdam model.
