The dynamics of multiple time use in paid work and in household activities with housework, child rearing and DIY of married women are analyzed with a two step procedure: the estimation of the participation decision in intertemporal labor force participation strategies (entering, leaving the...

We present a restriction on the domain of individual preferences that is both necessary and sufficient for the existence of a social choice rule that is continuous, anonymous, and respects unanimity. The restriction is that the space of preferences be contractible. Contractibility admits a...

This study on market and non-market labor supply and taxes is based on a theoretical microeconomic model with multiple labor supply in the formal and informal economy. This multiple time allocation model, which explicitly takes into account taxes, transfer payments, socioeconomic characteristics...

In this paper I describe certain results that were obtained in the UNITAR project based on a model I have specified for studying the relationship between international terms of trade and domestic income distributions of the exporting countries within the South. In particular, I shall concentrate...

In meiner Antrittsvorlesung versuche ich, meine Forschungs- und Lehrvorhaben in drei Themenkomplexen zu umschreiben. Der erste Themenbereich 'Statistik und Freie Berufe', zugleich Denomination meiner Professur, beschreibt nach den Charakteristika Freier Berufe Möglichkeiten und Grenzen der...

We study properties of the solutions to a parametrized constrained optimization problem in Hilbert spaces. A special operator is studied which is of importance in economic theory; sufficient conditions are given for its existence, symmetry, and negative semidefiniteness. The techniques used are...

This paper develops a dynamic model of North-South trade in which environment plays an important role. Our model is based on Chichilnisky North-South model for the macroeconomic interaction between two sectors of the world economy. The latter was introduced in a static context. We introduce...

Oil price behavior has changed dramatically in the last twenty years. These changes can be explained rather simply in terms of the delayed responses of supply and demand to prices, and in terms of changes in the rate of discovery of reserves. This analysis can be used to forecast possible future...

Die Freien Berufe und die staatlich gebundenen Freien Berufe agieren in einem wirtschaftsund gesellschaftspolitischen Spannungsfeld, dessen Pole durch Staat und den freien Markt gekennzeichnet werden. Der vorliegende Beitrag thematisiert Privatisierung und Deregulierung für die Freien Berufe...

As simple as it is, results describing the world are heavily dependent on the quality of the underlying data. One of the very crucial variables in microanalytical analyses of well-being and human resources is income. The more, when the situation of the self-employed is regarded. This paper focus...
