    Discrete Choice Labor Supply: Conditional Logit vs. Random Coefficient Models

    Estimating labor supply functions using a discrete rather than a continuous specification has become increasingly popular in recent years. On basis of the German Socioeconomic Panel (GSOEP) I test which specification of discrete choice is the appropriate model for estimating labor supply: the standard conditional logit model or the random coefficient model. To the extent that effect heterogeneity is ...

    Growth and Inflation Forecasts for Germany: An Assessment of Accuracy and Dispersion

    Based on a panel of German professional forecasts for 1970 to 2002 we find that growth and inflation forecasts are unbiased and weakly, but not strongly efficient. Besides the effect of diverging forecasting dates, no other substantial differences in forecasting quality are found among forecasters. We argue that is not always advisable to listen to the majority of forecast-ers. The dispersion of forecasts ...

    Social Identity and Group Lending

    The success of joint liability programs depends on nature and composition of borrowing groups. Group formation is a costly process and in our model these costs vary with the social identity of group partners. We show that risk heterogeneity in a borrowing group may arise due to the social identity of the agents. The presence of caste and gender bias may not resolve the adverse selection and moral hazard ...

    Rating Companies with Support Vector Machines

    The goal of this work is to introduce one of the most successful among recently developed statistical techniques - the support vector machine (SVM) - to the field of corporate bankruptcy analysis. The main emphasis is done on implementing SVMs for analysing predictors in the form of financial ratios. A method is proposed of adapting SVMs to default probability estimation. A survey of practically and ...

    Valuation for Sustainable Development: The Role of Multicriteria Evaluation

    Multikriterienmethoden erweisen sich als nützlich, um die Entscheidungsfindung in komplexen Situationen - wie solche eine nachhaltige Entwicklung betreffend - zu unterstützen und um mit Konflikten in einer strukturierten und transparenten Art umzugehen. Zunehmend wird multikriterielle Bewertung auch als konstruktive Antwort aufdie Kritik der Kosten-Nutzen-Analyse gesehen. Die multikriterielle Bewertung ...

    Measuring State Dependence in Individual Poverty Status: Are there Feedback Effects to Employment Decisions and Household Composition?

    Using a sample of prime-aged men from the German Socio-Economic Panel (GSOEP), this paper examines the effects of past poverty experience on future poverty status, future employment status and household composition. The empirical results suggest that even after controlling for observed and unobserved characteristics, past poverty experience increases the poverty risk of future periods. Moreover, there ...
