| ''Testing for Shape Invariance of Semiparametric Equivalence Scales'' |
| ( 2007, Vol. 4 No.21 ) |
| |
| |
| Within a semiparametric framework we propose a test of shape invariance of Engel curves, which is a necessary condition for base independence. Using Canadian family expenditure data for 1996 we reject shape invariance for the fuel and clothing share equations. |
