Elicitability and identifiability of set-valued measures of systemic risk

Using Polynomial Regression Analysis and Response Surface Methodology to Make a Stronger Case for Value Congruence in Place Marketing

Values are an important concept in marketing because they comprise part of peoples’ identity and can thus help marketers separate and target different audiences. Unsurprisingly, places and their marketing initiatives increasingly try to appeal to (potential) residents’ identity by communicating core values. While the notion of value congruence is not novel, most empirical methods in marketing to date only account for the degree rather than the level of congruence. To address this issue, the present article utilizes polynomial regression and response surface methodology (Edwards & Parry, 1993 ) in the context of place marketing. Accordingly, the first study shows that the perceived congruence of residents’ own values and the values of stereotypical city inhabitants significantly affect residents’ feelings about their own cities (N = 1257), but with different effects for different values and levels of congruence. This finding holds not only for popular target groups such as the “creative class” but also across all groups. The second study (N = 449) shows that city slogans can effectively communicate specific values and that value congruence leads to a more positive evaluation of the city brand. Finally, the article discusses the benefits of differentiating between levels of congruence both in marketing research in general, and place brand management in particular.     

Bayesian inference in a correlated random coefficients model: Modeling causal effect heterogeneity with an application to heterogeneous returns to schooling

We consider the problem of causal effect heterogeneity from a Bayesian point of view. This is accomplished by introducing a three-equation system, similar in spirit to the work of Heckman and Vytlacil (1998), describing the joint determination of a scalar outcome, an endogenous “treatment” variable, and an individual-specific causal return to that treatment. We describe a Bayesian posterior simulator for fitting this model which recovers far more than the average causal effect in the population, the object which has been the focus of most previous work. Parameter identification and generalized methods for flexibly modeling the outcome and return heterogeneity distributions are also discussed.Combining data sets from High School and Beyond (HSB) and the 1980 Census, we illustrate our methods in practice and investigate heterogeneity in returns to education. Our analysis decomposes the impact of key HSB covariates on log wages into three parts: a “direct” effect and two separate indirect effects through educational attainment and returns to education. Our results strongly suggest that the quantity of schooling attained is determined, at least in part, by the individual’s own return to education. Specifically, a one percentage point increase in the return to schooling parameter is associated with the receipt of (approximately) 0.14 more years of schooling. Furthermore, when we control for variation in returns to education across individuals, we find no difference in predicted schooling levels for men and women. However, women are predicted to attain approximately 1/4 of a year more schooling than men on average as a result of higher rates of return to investments in education.     

Validating an innovative real-time Delphi approach - A methodological comparison between real-time and conventional Delphi studies

A novel and innovative real-time Delphi technique is introduced in order to address previously identified weaknesses of the conventional Delphi method, such as complicated facilitator tasks, lack of real-time presentation of results, and difficulties in tracking progress over time. We demonstrate how the real-time (computer-based) method increases the efficiency of the process, accommodates expert availability, and reduces drop-out-rates. Modifications in the Delphi procedure (e.g. change of iteration principle) not only increase efficiency but also change the nature and process of the survey technique itself. By identifying and analysing three individual effects (initial condition effect, feedback effect, and iteration effect) we examine whether the modifications in the survey process cause deviations to the survey results. Empirical data obtained from both conventional as well as real-time Delphi studies is analysed based on multiple statistical analyses. The research findings indicate that significant differences between the two Delphi survey formats do not exist and final survey results are not affected by changes in the survey procedure.     

Prävention und Management von Staatsinsolvenzen in der Europäischen Währungsunion

Der Umgang mit den Schuldenkrisen in einigen Eurol?ndern steht derzeit ganz oben auf der Tagesordnung der EWU-Gremien. Der Rettungsschirm zur aktuellen Krisenbew?ltigung ist allerdings bis 2013 befristet. Danach sollte ein dauerhafter Krisenpr?ventions- und Krisenmanagementmechanismus eingesetzt werden. Wie ein solcher Mechanismus zu gestalten ist, erl?utern die Autoren in diesem Beitrag.     

The paradox of tie strength in customer relationships for innovation: a longitudinal case study in the sports industry

Current literature argues that firms should have strong ties to customers to benefit from increased customer retention and loyalty. Strong ties, however, have also shown to prevent innovation, suggesting that firms should also develop weak ties to other customer groups. This paper focuses on the potential for strong ties to facilitate, rather than prohibit, innovation. It is based in a 7‐year longitudinal research project with Adidas, a global sporting goods company. From the case, we find that the paradox of tie strength results from an overly simplified view of the nature of company–customer relationships. Contrary to the established literature, we find that strong ties in the Adidas case supported significant innovation. In fact, the involvement resulted in the development of a new product with a radically different product architecture and led to one of the most successful product launches in the company's history. To explain these findings, we introduce the nature of customer participation in a firm's value creation processes as a new dimension of the constitution of firm–customer ties and discuss how such a kind of relationship can develop.     

Are family‐friendly workplace practices a valuable firm resource?

We study the determinants and consequences of family‐friendly workplace practices (FFWP) using a sample of over 450 manufacturing firms in Germany, France, U.K., and U.S. We find a positive correlation between firm productivity and FFWP. This association disappears, however, once we control for a measure of the quality of management practices. We further find that firms with a higher proportion of female managers and more skilled workers, as well as well‐managed firms, tend to implement more FFWP. Conversely, a firm's environment does not have a significant impact on the FFWP it provides. © 2010 The Authors. Strategic Management Journal published by John Wiley & Sons, Ltd.
