Business Conditions and Exit Risks Across Countries

The risk of market exit that business firms face is significant and differs widely across countries. This paper explores the links between countries’ business conditions and the exit risk at the country level. We set up a general equilibrium model which allows us to derive sharp predictions concerning how key factors which shape a country’s business and trade environment impact on the exit risk of firms which operate in these environments. The model is able to explain the negative correlation between countries’ average labor productivity and the perceived risks of exit borne out in the facts and its predictions accord with evidence on country differences in business conditions.

Auswirkungen von betrieblichen Work-Life Balance Maßnahmen auf Unternehmen: Stand der empirischen Forschung

Business practice is generally of the opinion that measures for increasing the employees’ work life balance (WLB) are useful for all parties, i.e. also for the companies. This paper analyzes empirical studies which investigate operational effects of WLB measures in companies. Except of the result of one study, researchers revealed only positive effects of WLB for companies. This statement, however, is insufficient to verify the actual operational effects of WLB measures due to methodical and content deficits. Considering this background, the paper develops implications for future research.     

Conference report: Second conference on political marketing: Judge institute of management studies,university of Cambridge 27–29 March 1996

Sales promotion activity continues to grow in terms of the number, scale and variety of promotional techniques being used by companies in their marketing communication campaigns. Research among marketing academics has yet to catch up with this reality and sales promotion continues to suffer from relative neglect compared to advertising;from a tendency for all promotional tools to be tarred with a rational economic brush; and from being labelled as a set of “tactical” took that lack the strategic brand‐building possibilities offered by advertising. This article builds upon earlier research examining the communication potential of competitions, to test empirically whether the potential marketing communications benefits claimed for competitions are actually recognised and pursued by marketing practitioners.     

Organizational Performance Consequences of Age Diversity: Inspecting the Role of Diversity‐Friendly HR Policies and Top Managers’ Negative Age Stereotypes

This paper seeks to advance the diversity literature by investigating organizational performance consequences of age diversity. Drawing from social‐identity and social‐categorization theory, we theoretically argue that, in age‐diverse companies, age‐based subgrouping processes occur, favouring a shared perception of a negative age‐discrimination climate. This perceived negative age‐discrimination climate in turn negatively relates to organizational performance. As the main contribution, top managers’ negative age‐related stereotypes and diversity‐friendly HR policies are introduced as organizational‐level moderators that increase and attenuate, respectively, the social categorization processes affecting performance in age‐diverse companies. We utilized structural equation modelling (SEM) to test the proposed hypotheses using a multisource dataset comprising 147 companies. The results supported all hypotheses, indicating that low negative top managers’ age stereotypes as well as high diversity‐friendly HR policies are potential organizational factors that can prevent the negative relation of age diversity with organizational performance transmitted through the negative age‐discrimination climate. These results are discussed in light of their contribution to the diversity literature and social‐categorization theory as well as their implication for practitioners.     

Die Bundesbank und ihre Rolle im unbaren Zahlungsverkehr

Die Bundesbank spielt eine bedeutende Rolle im unbaren Zahlungsverkehr in Deutschland und der Eurozone. Sie hat die Aufgabe, einen reibungslosen und insbesondere sicheren Zahlungsverkehr zu gew?hrleisten. Die Besonderheit des Marktes für Zahlungsverkehrssysteme macht es — den Autoren zufolge — notwendig, dass eine unabh?ngige Zentralbank als staatlicher Anbieter im Markt auftritt.

What do we really know? Metrics for food insecurity and undernutrition

In this article, we critically review the three most common approaches of assessing chronic food insecurity and undernutrition: (i) the FAO indicator of undernourishment, (ii) household food consumption surveys, and (iii) childhood anthropometrics. There is a striking and worrying degree of inconsistency when one compares available estimates, which is due to methodological and empirical problems associated with all three approaches. Hence, the true extent of food insecurity and undernutrition is unknown. We discuss strengths and weaknesses of each approach and make concrete suggestions for improvement, which also requires additional research. A key component will be the planning and implementation of more comprehensive, standardized, and timely household surveys that cover food consumption and anthropometry, in addition to other socioeconomic and health variables. Such combined survey data will allow much better assessment of the problems’ magnitude, as well as of trends, driving forces, and appropriate policy responses.     

On the Applicability of the Sieve Bootstrap in Time Series Panels*

In this article, we investigate the validity of the univariate autoregressive sieve bootstrap applied to time series panels characterized by general forms of cross‐sectional dependence, including but not restricted to cointegration. Using the final equations approach we show that while it is possible to write such a panel as a collection of infinite order autoregressive equations, the innovations of these equations are not vector white noise. This causes the univariate autoregressive sieve bootstrap to be invalid in such panels. We illustrate this result with a small numerical example using a simple DGP for which the sieve bootstrap is invalid, and show that the extent of the invalidity depends on the value of specific parameters. We also show that Monte Carlo simulations in small samples can be misleading about the validity of the univariate autoregressive sieve bootstrap. The results in this article serve as a warning about the practical use of the autoregressive sieve bootstrap in panels where cross‐sectional dependence of general form may be present.
