Estimation of Nonlinear Models with Measurement Error

This paper presents a solution to an important econometric problem, namely the root n consistent estimation of nonlinear models with measurement errors in the explanatory variables, when one repeated observation of each mismeasured regressor is available. While a root n consistent estimator has been derived for polynomial specifications (see Hausman, Ichimura, Newey, and Powell (1991)), such an estimator for general nonlinear specifications has so far not been available. Using the additional information provided by the repeated observation, the suggested estimator separates the measurement error from the “true” value of the regressors thanks to a useful property of the Fourier transform: The Fourier transform converts the integral equations that relate the distribution of the unobserved “true” variables to the observed variables measured with error into algebraic equations. The solution to these equations yields enough information to identify arbitrary moments of the “true,” unobserved variables. The value of these moments can then be used to construct any estimator that can be written in terms of moments, including traditional linear and nonlinear least squares estimators, or general extremum estimators. The proposed estimator is shown to admit a representation in terms of an influence function, thus establishing its root n consistency and asymptotic normality. Monte Carlo evidence and an application to Engel curve estimation illustrate the usefulness of this new approach.     

The hidden majority/minority consensus: Minorities show similar preference patterns of immigrant support as the majority population

The acceptance of new arrivals has become an important topic regarding the social cohesion of the receiving countries. However, previous studies focused only on the native population's drivers of attitudes towards immigrants, disregarding that immigrant-origin inhabitants now form a considerable part of the population. To test whether the drivers for the willingness to support immigrants are the same for natives and immigrants and their descendants, we rely on a vignette study conducted in a representative German online panel (N = 3149) which contains an overrepresentation of immigrant-origin respondents. We presented participants with three vignettes of potential immigrants, varying, amongst other factors, economic prospects, safe and war-ridden countries of origin (to capture deservingness), as well as religious identity. While we find that minority members are generally slightly more welcoming towards immigrants than majority members, at their core are the same factors that drive attitudes to immigrants in both groups: economic cost, cultural similarity, and deservingness. However, we observe differences at the margins: Immigrant-origin respondents take into account economic prospects to a lesser degree than majority members do, and by trend, they are less likely to distinguish between immigrants from war-ridden and safe countries of origin. Furthermore, we can show that the preference for immigrants with the same religious identities not only occurs among majority members but also among minority members.     

Well-being and Mobility: A Theoretical Framework and Literature Review Focusing on Older People

There is an increasing attention for how mobility is associated with well-being amongst people in general and older adults in particular. Comparisons across research projects and articles are, however, hampered by the different understandings and conceptualisations of well-being that are employed. We, firstly, develop a heuristic framework for understanding the concept of well-being, and secondly, use this to explore possible linkages between well-being and mobility and to critically examine the various conceptualisations of well-being in research on mobility in later life. It is argued that future work on well-being and mobility should consider both the objective and the subjective and the hedonic and eudaimonic dimensions of well-being, and should pay detailed attention to the multiple ways in which well-being and its linkages to mobility are context-dependent and shaped by the particularities of time and place.     

THE EFFECTS OF FINANCIAL AND RECOGNITION INCENTIVES ACROSS WORK CONTEXTS: THE ROLE OF MEANING

We manipulate workers' perceived meaning of a job in a field experiment and interact meaning of work with both financial and recognition incentives. Results show that workers exert more effort when meaning is high. Money has a positive effect on performance that is independent of meaning. In contrast, meaning and recognition interact negatively. Our results provide new insights into the stability of incentive effects across important work contexts. They also suggest that meaning and worker recognition may operate via the same motivational channel. (JEL C93, J33, M12, M52)     

K?nnen Studienbeitr?ge die Lehre in der BWL verbessern?

The introduction of tuition fees by some German universities raised fears about possible negative effects, which scientific research has not substantiated, though. Meanwhile, little attention has been paid to positive effects tuition fees might entail. This is surprising as universities are obliged to use tuition fees to improve study conditions. Business programs are highly frequented with limited academic staff. More assistance would therefore improve study conditions substantially. Tutorials funded by fees can be introduced quickly and, unlike faculty positions, do not tie up money in the long run. This makes them ideal to cope with the one-time enrollment peak due to the shortening of secondary education. We show that tutorials improve both satisfaction and study outcomes. We use data from an introductory course characteristic of business programs, where tutorials have been introduced. This course is attended by about 750 students per term and the data cover several terms. We control for a number of effects, including general academic ability. Increased satisfaction and improved study outcomes show that tutorials enhance both the objective and perceived study conditions. This makes tutorials an example of how tuition fees can be used to produce positive effects.     

Situation-based measurement of the full range of leadership model — Development and validation of a situational judgment test

In response to calls for context-specificity in leadership research, we developed and validated a Situational Judgment Test of the Full Range of Leadership Model (SJT-FRLM). Three consecutive studies were conducted following the typical steps of test development. Study 1 served measure development and pilot testing: item stems were generated empirically, item responses were developed with a theory-driven approach, and pilot testing was based on a leader sample. Study 2 served to analyze construct- and criterion-related validity of the instrument. Moreover, an empirical scoring key was developed that weights each item response according to its relation with leadership effectiveness in each situation. In Study 3, we demonstrated incremental validity and interrater agreement. The test fills an important gap in literature because it not only has predictive validity above and beyond established measures, but also takes into account the contextual element of leadership.     

Transformational leadership,job satisfaction,and team performance: A multilevel mediation model of trust

In spite of calls for deliberate differentiation between individual and team levels of analysis, leadership research based on well-grounded theory referring to multiple levels is scarce. We seek to fill this gap by analyzing the relations between transformational leadership, trust in supervisor and team, job satisfaction, and team performance via multilevel analysis. Results are based on a sample of 360 employees from 39 academic teams. Transformational leadership was positively related to followers' job satisfaction at individual as well as team levels of analysis and to objective team performance. The relation between individual perceptions of supervisors' transformational leadership and job satisfaction was mediated by trust in the supervisor as well as trust in the team. Yet, trust in the team did not mediate the relationship between team perceptions of supervisors' transformational leadership and team performance. Implications for theory and research of leadership at multiple levels as well as for practice are discussed.     

A Measure of Accountability: Clients' Perceptions of a University Mental Health Service

Abstract

The University Counseling Center at the State University of New York at Stony Brook has developed a psychodynamic model for brief therapy in order to meet increased demands for service with limited staff resources. Because the center has both a multidisciplinary staff and graduate student training program, the aim of the model was to translate already existing theories of time-limited psychotherapy into practical, usable, teachable techniques. A major issue addressed was the reluctance to accept brief therapy because of its perception of being superficial and amenable only to symptom relief as opposed to “preferred” long-term treatment, seen as providing in-depth change and personality reorganization.

The model developed is based on one or two assessment sessions followed by eight sessions of treatment. The major distinguishing characteristic of the model consists of the explicit setting of two goals with the patient. Goal I is based on an assessment of the presenting problem and is directed toward symptom relief. Goal II is based on a characterological-thematic assessment of the patient and is directed toward major theme-process issues in which the presenting problem is imbedded. The eight treatment sessions are seen as a dynamic whole. Both goals I and II are explicitly contracted for, and each session number is announced by the therapist.

Experience with the model to date has shown that eight sessions produce characteristic initial, middle, and late sessions, with planned termination, a powerful, dynamic feature not usually utilized with many psychotherapies in which natural or calendar events tend to provide motivation for termination. In addition, major characterological changes can begin when the patient participates in the ego-synthesizing function of understanding the thematic issues within which specific behaviors and emotional reactions are a part.     

Differential Reliance on the Duchenne Marker During Smile Evaluations and Person Judgments

When evaluating the smiles of other people (regarding amusement, authenticity, spontaneity, or intensity), perceivers typically rely on Orbicularis oculi activity that causes wrinkles around a target’s eyes. But does this so-called Duchenne marker also impact more generalized judgments of person characteristics (e.g., regarding a target’s attractiveness, intelligence, dominance, and trustworthiness)? To address this issue, the current study asked participants to provide the above smile evaluations and person judgments for a series of Duchenne and non-Duchenne smiles. The results showed that smile evaluations uniformly increased during Duchenne marker presence. The marker’s effect on person judgments, in contrast, was judgment dependent. While attractiveness, dominance and intelligence ratings showed the expected enhancement, trustworthiness ratings remained unaffected by the facial cue of interest. The findings suggest that the Duchenne marker’s role as a cue of social relevance during target perception depends on the type of person inference under consideration.
