Count data models for demographic data∗

Key demographic variables, such as the number of children and the number of marriages or divorces, can only take integer values. This papers deals with the estimation of single equation models in which the counts are regressed on a set of observed individual characteristics such as age, gender, or nationality. Most empirical work in population economics has neglected the fact that the dependent variable is a nonnegative integer. In the few cases where this feature was recognized, the authors advocated the use of the Poisson regression model. The Poisson model imposes, however, the equality of conditional mean and variance, a restriction which is often rejected by the data. We propose a generalized event count model to simultaneously allow for a wide class of count data models and account for over‐ and underdispersion. This model is successfully applied to German data on fertility, divorces and mobility.     

Ordered response models

Summary We discuss regression models for ordered responses, such as ratings of bonds, schooling attainment, or measures of subjective well-being. Commonly used models in this context are the ordered logit and ordered probit regression models. They are based on an underlying latent model with single index function and constant thresholds. We argue that these approaches are overly restrictive and preclude a flexible estimation of the effect of regressors on the discrete outcome probabilities. For example, the signs of the marginal probability effects can only change once when moving from the smallest category to the largest one. We then discuss several alternative models that overcome these limitations. An application illustrates the benefit of these alternatives. We are grateful to an anonymous referee for valuable comments.     

Die Esser-Luhmann-Kontroverse als unbefriedigender Streit um die Grundlagen der Soziologie

The controversy about the foundations of Sociology between Hartmut Esser und exponents of the sociologic systems theory hasn't yet been satisfactorily settled. A basic reason for this point is that there is no systematic analysis from a distant comparative point of view, of what in the conceptions of Esser and Luhmann is meant by ?social“ as their central topic. The consequence is a debate in which both their social theories are discussed in a limited and superficial way. To avoid this kind of limitations and to come to a fruitful dispute, the theories have to be discussed comparatively starting with Esser's ?Model of Sociological Explanation“ and with Luhmann's concept of ?social system“. Starting with such a systematic comparison, not only deficits of the controversy can be detected, but essential problems and errors of the approaches become visible too. From such a starting point something else can be developed: that the controversial positions of their conceptualizing, of what they understand to be the central topic of Sociology, is much less different than is supposed to be. The proposed method can also be used to validate Esser's claim to have integrated in his conception the various theories of Sociology.     

The Polish Peasant in Oberlin and Chicago

This paper examines the historical sources for W. I. Thomas and Florian Znaniecki’s celebrated monograph on The Polish Peasant in Europe and America. It first characterizes the work itself, a monumental interpretive casebook of largely biographical material about individuals and groups. It then seeks the origins of these qualities, looking first at Thomas’s prior work, then at the personal influence of Florian Znaniecki and Robert Park. Since these sources do not sufficiently account for the unique qualities of the work, we then turn to three other important sources: 1) the casebook tradition in the social reform literature and beyond, 2) the psychiatric concept of the life history, and 3) the literary sources that Thomas had taught in his prior career as an English professor. We close by identifying the autobiographical roots of the work in Thomas’s own life history.     

Conspicuous consumption and satisfaction

Traditional tools of welfare economics identify the envy-related welfare loss from conspicuous consumption only under very strong assumptions. Measured income and life satisfaction offers an alternative for estimating such consumption externalities. The approach is developed in the context of luxury car consumption (Ferraris and Porsches) in Switzerland. Results from household panel data and fixed effects panel regressions suggest that the prevalence of luxury cars in the municipality of residence has a negative impact on own income satisfaction.
