Consider the following model which relates the fraction (weight) of a household's budget spent on alcoholic beverages (BSALC) to total expenditure (BUDGET), age of the household head (AGE), and the number of children in the household (NKIDS). E(BSALC) = B1 + Bzln(BUDGET) + B3AGE + BANKIDS BSALC budget share (fraction) for alcohol expenditure BUDGET total household BUDGET (rounded to the nearest 10 UK pounds sterling) AGE age of household head NKIDS number of children 8 The value of coefficient b2 =. . This implies . a if BUDGET increases by 1%, the alcohol share will increase by 0.000265. b if BUDGET increases by 1%, the alcohol share will increase by .0265. C if BUDGET increases by 1 unit, the alcohol share will increase by 0.0265. d Both b and c are correct
