The senator’s tale: the development of Bremen’s bourgeoisie in the post-1945 era

Were members of the German bourgeoisie capable of forming the foundation for a new self-understanding of post-1945German society? Or did they prove to be unsuited as agents of Germany’s new beginning? This article seeks to answer these questions by focusing on historical developments in the early phase of the Federal Republic of Germany as reflected in the biography of one prominent representative of the German bourgeoisie. Theodor Spitta, who was born in 1873, was elected in 1911as a senator for life in the government of the Free Hanse City of Bremen. Spitta was an outstanding representative of a generation socialized under the last German Kaiser, a generation which perceived itself as part of a politically liberal Bremen bourgeoisie. He feared the gradual decline, indeed the disintegration of his class. None the less – or perhaps for that very reason – he committed himself to the goal of restoring a regionally specific form of bourgeois life in the city of Bremen. Although Spitta declared a ‘farewell to the bourgeoisie’ in his autobiographical texts, that did not prevent him from actively pursuing the revival of a unique urban-bourgeois ‘spirit’. This spirit was to serve as a tool in promoting Bremen’s central political goal in post-1945Germany: the preservation of the city-state’s unique status within Germany’s federal system.     

Assessing the impact of initial nonresponse and attrition in the analysis of unemployment duration with panel surveys

We show how register data combined at person-level with survey data can be used to conduct a novel type of nonresponse analysis in a panel survey. The availability of register data provides a unique opportunity to directly test the type of the missingness mechanism as well as estimate the size of bias due to initial nonresponse and attrition. We are also able to study in-depth the determinants of initial nonresponse and attrition. We use the Finnish subset of the European Community Household Panel (FI ECHP) data combined with register panel data and unemployment spells as outcome variables of interest. Our results show that initial nonresponse and attrition are clearly different processes driven by different background variables. Both the initial nonresponse and attrition mechanisms are nonignorable with respect to analysis of unemployment spells. Finally, our results suggest that initial nonresponse may play a role at least as important as attrition in causing bias. This result challenges the common view of attrition being the main threat to the value of panel data.     

HAC Corrections for Strongly Autocorrelated Time Series

Applied work routinely relies on heteroscedasticity and autocorrelation consistent (HAC) standard errors when conducting inference in a time series setting. As is well known, however, these corrections perform poorly in small samples under pronounced autocorrelations. In this article, I first provide a review of popular methods to clarify the reasons for this failure. I then derive inference that remains valid under a specific form of strong dependence. In particular, I assume that the long-run properties can be approximated by a stationary Gaussian AR(1) model, with coefficient arbitrarily close to one. In this setting, I derive tests that come close to maximizing a weighted average power criterion. Small sample simulations show these tests to perform well, also in a regression context.     

Efficient Institutions and Effective Deterrence: On Timing and Uncertainty of Formal Sanctions

Journal of Risk and Uncertainty - Economic theory suggests that the deterrence of deviant behavior is driven by a combination of severity and certainty of punishment. This paper presents the first...     

Risk Assessment for Interconnected Electrical Power Grids

Using an analogy with costs, risk is split into a fixed and a variable contribution. Based on this concept, the total risk of an interconnected electrical power grid is minimized. The theoretical foundations of the method are explained and illustrated by model calculations.     

Second modernity as a research agenda: theoretical and empirical explorations in the 'meta-change' of modern society

In this article we are reformulating the theory of reflexive modernization as an empirical research programme and summarize some of the most recent findings which have been produced by a research consortium in Munich (integrating four universities, funded by the German Research Society (DFG)). On this basis we reject the idea that Western societies at the beginning of the twenty-first century move from the modern to the post-modern. We argue that there has been no clear break with the basic principles of modernity but rather a transformation of basic institutions of modernity such as the nation-state and the nuclear family. We would suggest, therefore, that what we are witnessing is a second modernity. Finally, we reform the theory of reflexive modernization in reaction to three uttered objections.     

Bayesian predictive power: choice of prior and some recommendations for its use as probability of success in drug development

Bayesian predictive power, the expectation of the power function with respect to a prior distribution for the true underlying effect size, is routinely used in drug development to quantify the probability of success of a clinical trial. Choosing the prior is crucial for the properties and interpretability of Bayesian predictive power. We review recommendations on the choice of prior for Bayesian predictive power and explore its features as a function of the prior. The density of power values induced by a given prior is derived analytically and its shape characterized. We find that for a typical clinical trial scenario, this density has a u‐shape very similar, but not equal, to a β‐distribution. Alternative priors are discussed, and practical recommendations to assess the sensitivity of Bayesian predictive power to its input parameters are provided.

Nature and role of customer satisfaction in the solution business

The paper focuses on the solution business. Here we argue that the strategy can only lead a company to perform better if it encompasses a direct and positive effect on satisfaction with a supplier’s consulting capabilities. Hence we introduce the concept of consulting satisfaction, identify antecedents and analyze its consequences. To do so, we apply a mixed-methods approach. Content analysis from open interviews with company professionals yields a list of antecedents of consulting satisfaction used to devise a set of hypotheses. The latter was translated into a questionnaire based measurement instrument in order to first collect and then analyze data from a larger sample survey. Since three of the antecedents could not be supported by our study, possible explanations are presented. With our approach we tap new dimensions of solutions research. First, we inaugurate research on buying behavior within the field of solutions. Second, we stress the role of capabilities in this field and extend service–profit chain thinking. And third, we present consulting satisfaction as a lever to translate the S-D logic of marketing into more practical applications. To our knowledge this is a novel insight and can help industry decision makers better prepare for the solution business.     

Noise and bias in eliciting preferences

In the context of eliciting preferences for decision making under risk, we analyse the features of four different elicitation methods—pairwise choice, willingness-to-pay, willingness-to-accept, and the Becker-DeGroot-Marschak mechanism—and estimate noise, bias and risk attitudes for two different preference functionals, Expected Utility and Rank-Dependent Expected Utility. It is well-known that methods differ in terms of the bias in the elicitation; it is rather less well-known that methods differ in terms of their noisiness. It has also been reported that risk attitudes are not stable across different elicitation methods. Our results suggest that elicited preferences should only be used in the context in which they were elicited, and the bias in the certainty-equivalent methods should be kept in mind when making predictions based on the elicited preferences. Moreover, conclusions should be moderated to take into account the various methods’ noise, which is generally lowest in the case of pairwise choice.
