Although exam scores are reported using numerical values, their measurement scale is ordinal: They depend on the difficulty distribution of the questions in the exam. Hence, population groups or countries should not be ranked according to average exam scores because there may exist an admissible...

Different family types may have a fixed flow of consumption costs related to subsistence needs. We use a survey approach in order to identify and estimate such a fixed component of spending for different families. Our method involves making direct questions about the linkup between aggregate...

A distinguishing feature among households is whether adult members work or not, since the employment status affects a household's available time for home activities. Using a survey method in two countries, Belgium and Germany, we provide household incomes that retain the level of well-being...

Household consumption exhibits economies of scale as the number of household members increases. We collect survey data from two countries, Germany and France, in order to obtain direct subjective estimates of household consumption economies of scale, and, in particular, to examine an additional...

The book presents a new survey method for assessing equivalence scales. While previous surveys have frequently been accused of providing data which are substantially biased by respondents' personal characteristics and other subjective biases the new method keeps bias to an absolute minimum....

Equivalence Scales are a tool for removing the heterogeneity of household sizes in the measurement of inequality, and affect poverty assessments and poverty lines. We address the disadvantage that poor households may suffer due to their reduced ability to share goods within the household. This...

Recent studies in high-income industrialized countries have shown that equivalence scales are income-dependent. We investigate whether this dependence also holds in poorer, services oriented countries, by considering the example of Cyprus. We also examine whether household economies of scale and...

Micro-econometric intra-cohort profitability analyses of pay-as-you-go (PAYG) pension contributions are rare. We use representative employment histories of a birth cohort of German PAYG pension insurants retiring in year 2005 to econometrically examine the determinants of the profitability of...
