This paper provides families of time-separable, twice continuously di?erentiable, and strictly concave utility functions of a group of consumers that are both su?cient and necessary in order to have linear aggregation in a single-commodity-type deterministic dynamic environment, in the presence...

A distinguishing feature among households is whether adult members work or not, since the occupational status of adults affects their 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...

Different family types may have a fixed flow of consumption costs, related to subsistence needs. We use a survey method 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 a?ects 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...

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...

We study the impact of uncertainty on the strategies and dynamics of symmetric noncooperative games among players who exploit a non-excludable resource that reproducesunder uncertainty. We focus on a particular class of games that deliver a unique Nash equilibrium in linear-symmetric strategies...

Increasing marginal tax rates and making payments to the poor reduce inequality and introduce savings dis-incentives. Using a heterogeneous agent model with incomplete markets, we show that higher taxes (and transfers) decrease consumption inequality but also mean savings and mean consumption....

Um die Arbeitsanreize und die Verteilungsgerechtigkeit des Arbeitslosengeldes II (ALG II) zu analysieren, ist eine Quantifizierung des Arbeitsleides und des Wertes der Haushaltsproduktion in verschiedenen Haushaltstypen notwendig. Da diese Größen nicht direkt beobachtbar sind, verwendet die...

Raising children demands a considerable amount of parental time, obliging working parents either to reduce their leisure time further or to buy childcare services in the market. Parents may face additional opportunity costs upon deciding to participate in the labor market, but these are...
