    Abstract: In der ökonomischen Zufriedenheitsforschung wird ein negativer Effekt von Kindern auf die elterliche Zufriedenheit ermittelt. Dazu werden oftmals Probitmodelle geschätzt. In diesem Papier wird nun ein fixed effects Modell benutzt. Mittels Daten des Sozioökonomischen Panels (SOEP) werden Personen betrachtet, die im Zeitablauf zu Eltern werden. Es ergibt sich ein signifikant positiver Effekt von Kinder im Haushalt. Weiterhin werden Interaktionsterme gebildet, um Effekte individueller Arbeitslosigkeit einzufangen. Bei arbeitslosen Väter sinkt deutschlandweit die Zufriedenheit. Arbeitslose Mütter erleben in den alten Bundesländern einen positiven Zufriedenheitseffekt, in den neuen einen Negativen. Dies wird als Folge von regional unterschiedlichen weiblichen Erwerbsmustern in Deutschland interpretiert.

    Abstract: Taking into account the Swiss experience, this paper considers some aspects of the current reform discussion concerning the German health insurance system. The income dependence of effective premia, their size and their distributional consequences are discussed. The potential role of competition is also considered. It is shown that there are only gradual but no systematic differences between the current German and Swiss systems with respect to their labour market consequences that are central to the present German discussion, while those aspects where the two systems really differ are rarely ever discussed, and the planned new German system will hardly differ in these other dimensions from the old one.

    Abstract: Discussions of health care reforms are always tightly connected with the question of ensuring equity in financing health care. This paper analyses the German health care reform 2007 and its effect on the equity of health care financing. To do this Rawls’ and Nozick’s perceptions of justice will be applied to develop benchmarks to classify new financing options introduced with the reform. These benchmarks are indicated through a differentiation between the two principles „fair compensation for performance“ and „equitable support based on need“ and the extent of income redistribution of the new financing modes. Overall, it can be concluded that the health care reforms have not reduced equity in health care financing neither if Rawls’ perception of justice is applied nor if the conception of justice held by Nozick is applied.

    Abstract: Central question in our analysis is if voluntarily organised Professions, i.e. self-employed Liberal Professions (Freiberufler) in professional organisations, yield a higher income than those not associated to any professional organisation. To answer this question four waves from the German Socio-Economic Panel Survey Study (GSOEP) are used. Descriptive statistics show a positive link of gross monthly income and those who are voluntarily associated in professional organisations. Because gross monthly income is influenced by the amount of actual hours worked, gross hourly income is the central magnitude of interest. The aforementioned positive link is widely confirmed by descriptive statistics of corresponding gross hourly income. To measure causal effects through voluntary membership in professional organisations a fixed-effects-model in consideration of unobserved and time constant heterogeneity is estimated. We find a negative premium in gross hourly income for voluntarily organised Professions which varies between -7,67 und -9,15 %.

    Abstract: It is common sense that the self-employed – as professions and entrepreneurs – are rich by money and, because of their independence and time sovereignty, are rich by time, too. However, time stress and the variety of small businesses sometimes tell another story. This study tries to shed empirically based light on the issue and its dynamics by asking not only about income poverty but also about time poverty within the framework of a new interdependent multidimensional poverty approach. Database is the German Socio-Economic Panel (GSOEP) for the evaluation of the substitution/trade-off of genuine leisure time and income as well as the German Time Use Surveys (GTUS) 1991/92 and 2001/02 for the actual poverty analyses. Main result: The self-employed are more often affected by single income poverty, single time poverty as well as interdependent multidimensional time and income poverty than all other poor employees (“working poor”) for both periods of observation. A remarkable percentage of not income poor but time poor employees in general, and the self-employed in particular, is not able to compensate their time deficit by income. Neglecting the self-employed in the poverty and well-being discussion would disregard an important group of the “working poor”.

    Abstract: Standard international trade lectures normally comprises three central theories: the Ricardian Model, the Heckscher-Ohlin-Samuelson Modell and New Trade Theory à la Krugman 1979 and 1980. Nowadays this trilogy needs to be enhanced with the basic concepts of a new class of trade models: the New New Trade Theory which accounts for firm heterogeneity and market entry costs. The basic objective of this paper is to present the contribution of Marc J. Melitz in Econometrica 2003 which is central to this new class of trade theory. I show how it is embedded in antecedent theory and highlight the new insights for trade patterns stemming from it. --

    Abstract: This paper describes a measurement approach for detecting sympathy and self-confidence based on speech characteristics as investigative personal assessment. The advantages of this automatic real time approach are that obtaining speech data is objective and non obtrusive, and it allows multiple measurement over long periods of time. Different types of acoustic features were computed. In order to identify speech correlates of self-confidence and sympathy, 10 actors were recorded, resulting in 100 segments of speech. 12 raters independently labeled the sympathy and self-confidence impression of the speech segments. Validation strategies reaching recognition rates for 2-class problems of 62.75-76.47 %, in classifying slight from strong sympathy and self-confidence.

    Abstract: This study analyses how different working hours arrangements influence the subjective job satisfaction. The paper contributes to the existing literature dealing with job satisfaction by including information on the flexibility of working hour arrangements and the compensation for working overtime. At first we describe the spread of flexible working hours arrangements over time in Germany. Based on data from the German Socio-economic Panel (SOEP) waves 2005 and 2007 we estimated a fixed-effects model and find a positive effect on job satisfaction of self-determined working hours of full time employees. Considering part time employees we find a clear preference of paid overtime over all other compensation options. Contrary to our expectations there is only little effect of the timing of daily demand on job satisfaction.
