Testing for Shape Invariance of Semiparametric Equivalence Scales
نویسندگان
چکیده
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. ∗The first author would like to acknowledge SSHRC of Canada for financial support.

Estimates of Semiparametric Equivalence Scales
Within the semiparametric framework introduced by Pendakur (1999) we introduce a new loss function to estimate equivalence scales. This loss function uses all available information from the total expenditures of both the reference and nonreference households and as such it produces more reliable estimates. We also use the correlation coefficient to directly test the hypothesis of shape invarian...
متن کاملSemiparametric Estimation of Consumption Based Equivalence Scales: The Case of Germany
Consumption based equivalence scales are estimated by applying the extended partially linear model (EPLM) to the 1998 Income and Consumption Survey (EVS) of Germany. The chosen flexible semiparametric specification is able to capture a large variety of functional forms of household expenditure shares; it yields √ N−consistent parameter estimates and is consistent with consumer theory. The model...
متن کاملSemiparametric Estimation of Lifetime Equivalence Scales
Pashardes (1991) and Banks, Blundell and Preston (1994) use parametric methods to estimate lifetime equivalence scales. Their approaches put parametric restrictions on the differences in within-period expenditure needs across household types, the intertemporal allocation of expenditure, and the shapes of commodity demand equations. This paper puts parametric structure only on the differences in...
متن کاملTesting the measurement equivalence of personality adjective items across cultures
Although previous research has examined cross-cultural differences in personality, many of these studies neglected to first establish that the measures being used were equivalent in meaning across cultures. Using samples of Chinese, Greek, and American respondents, the measurement equivalence of the Big Five Mini-Markers [Saucier, G. (1994). Mini-markers: A brief version of Goldberg’s unipolar ...
متن کاملHypothesis testing in semiparametric additive mixed models.
We consider testing whether the nonparametric function in a semiparametric additive mixed model is a simple fixed degree polynomial, for example, a simple linear function. This test provides a goodness-of-fit test for checking parametric models against nonparametric models. It is based on the mixed-model representation of the smoothing spline estimator of the nonparametric function and the vari...
