Where: ***, **, * denote 1%, 5% and 10% statistical significance.
The demand function has the form: LogQrice = f(log(X))
LogQrice denotes natural logarithm of demanded quantity of beans
X is a matrix including beans price, maize price, gari price, yam price, rice price,

household size, household income.
a. Analyze:
- The effects of each determinant on demanded quantity of beans (2 points)


- The effect of price of beans on the demanded quantity of other goods? (1 point)
