Semiparametric Estimation of Regression Functions Under Shape Invariance Restrictions
Wilke, Ralf A. - 2003
This paper considers the shape invariant modelling approach in semiparametric regression estimation. Nonparametric functions of similar shape are linked by parametric transformations with unknown parameters. A computationally convenient estimation procedure is suggested. √N- consistency of the...

Semiparametric Estimation of Consumption Based Equivalence Scales: The Case of Germany
Wilke, Ralf A. - 2004
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...

Consumption and nutrition: age - intake profiles for Czechoslovakia 1989 - 1992
Miquel, Ruth; Laisney, François - 2000
This paper provides non-parametric estimates of the relation between nutrient intake and age for Czechoslovak individuals, as a function of characteristics of both the individual and the household she lives in, on the basis of household purchases. Results show no significant difference between...

Semiparametric Estimation of Consumption Based Equivalence Scales: The Case of Germany
Wilke, Ralf A. - 2005
Consumption based equivalence scales are estimated by applying the extended partially linear model (EPLM) to the 1998 Income and Consumption Survey (EVS) carried out in Germany. In this model the equivalence scales are identified by virtue of nonlinearities in household demand. Therefore, the...

Age and productivity: Sector differences?
Göbel, Christian; Zwick, Thomas - 2011
In most industrialised countries, the workforce is ageing rapidly. If ageing workforces affect sectors differently, the … possibilities to compensate deficits in skills differ between sectors. We investigate differences in the age-productivity profiles … between the (metal) manufacturing and services sectors. However, in our preferred specification that controls for several …
