The case deals with forecasting the market demand for a leading brand of vegetable oil called "Vanaspati." The problem is viewed from the point of view of a company that controls a substantial market share of this product in India. Students are asked to prepare a longterm forecast of the company's market share. To be able to do this, they must first estimate the national demand for "Vanaspati" for the target year. A logarithmic model using income as the independent variable is the main tool of analysis. The students are exposed to the concepts of income elasticity, price elasticity and cross elasticity.
