Abstract
This paper is one of a series based on
original research conducted by Christopher Yandle at Lincoln on the New Zealand Meat Market. In the course of this
work the author conducted a questionaire survey of 300
families in Christchurch in which heads of families
were asked to indicate their basic preferences for
different meats, and to record their actual expenditure
on meat along with family income for a given week. This paper deals at a more technical level with the analysis of this
data in particular with the derivative of Engel Curves
showing the relationship between consumers incomes and their purchases of meat. The subject is the estimation of Engel curves from survey data. A review is made of the appropriate economic theory,
and the application of that theory to market generated data.
