Climate policy targets in emerging and industrialized economies: the influence of technological differences, environmental preferences and propensity to save

Although emerging economies claim that industrialized countries need to reduce their carbon emissions first, stabilization of the future global climate system requires immediate action by all countries. In a stylized two-country intertemporal general equilibrium model, we derive welfare maximizing emission caps in emerging and industrialized countries, taking account of country differences in technology, environmental preferences and propensity to save. Simultaneous target setting is compared to a sequential one in which the industrialized country commits itself to binding targets first. In the latter case, when the industrialized economy has stronger environmental preferences and a lower relative pollution production share, the industrialized economy can increase its joint economic and environmental welfare by setting a laxer target. On the other hand, when the emerging economy has considerably higher environmental preferences, our results suggest that the industrialized economy will choose a more restrictive target in a sequential setting than in a simultaneous one, contrary to first thought that a first mover is always pursuing a ‘symbolic’ policy with a lax target.     

Womit befassen sich kommunikationswissenschaftliche Abschlussarbeiten?

Transfer is an e-journal of the German academic association of journalism and communication (DGPuK), publishing abstracts of excellent theses in communication in German speaking countries. Since 1999, more than 1.000 abstracts have been collected. This article presents a content analysis of all abstracts published between 1999 and 2008 (n?=?1.056). The objective is to contribute to the ongoing debate about the identity of German speaking communication research and thus adding results to existing studies on journal publications and surveys among researchers. The content analysis examines the issues, the media analyzed, the use of theoretical and empirical approaches and the dominance of public communication as issue – as compared to interpersonal communication – of the studies, based on the abstracts published. Results show that the issues analyzed and the methods applied have not changed much over the years. A somehow alarming result is the fact that only very few abstracts explicitly refer to a theory. This raises the question of the deceasing relevance of theories in today’s communication research.     

A model of task demands,social structure,and leader–member exchange and their relationship to job satisfaction

In the present study, we examine task demands, leader–member exchange, and social structure in their relationship to job satisfaction. Based on the reflections of Seers and Graen in their dual attachment model, in the present study we combined task demands, leader–member exchange, and social structure in a model of antecedents of job satisfaction. The resulting model was tested using structural equation modelling. While task demands and leader–member exchange are related to their respective equivalents in job satisfaction, social structure is positively related to a latent factor job satisfaction, indicating that the social structure of a job has an impact on different facets of job satisfaction. The results are discussed with respect to sample characteristics.

Does North-South horizontal intra-industry trade really exist? An analysis of the toy industry

Does North-South Horizontal Intra-Industry Trade Really Exist? An Analysis of the Toy Industry. — In a combination of a case study approach and econometric analysis, bilateral intra-industry trade between high income countries and low income countries in the toy industry is investigated. In a number of products there is important bilateral intra-industry trade between both groups of countries. Econometric analysis in which a number of the explanatory variables used were quantified on the basis of the information supplied by the industry-spokesmen yields results which strongly support the view that the bilateral IIT between the high income countries and the low income countries in the toy industry is determined significantly by horizontal product differentiation and economies of scale.     

Das Paradox der Medienwirkung auf Nichtnutzer

The article presents data from a secondary analysis of the project »Wählerwanderungen und Politikverdrossenheit« from 1994. The data allow to conduct time series analysis on a day-to-day basis. The focus is agenda setting in combination with a thesis formulated by Marcus Maurer — published in Publizistik 2004 — on the paradox of media effects on non-users. In contrast to Maurer, the paper is not concerned with the methodological but the theoretical paradox: Can there be such a thing as media effects on media non-users? The hypothetical effect is analyzed in comparison of daily and less than daily TV news users. The analyzed models confirm the agenda-setting effect: The media agenda affects the public agenda at later points in time, but the public agenda does not have effects on the later media agenda. In addition, there are indirect effects on people who seldom use TV news. As they do not watch every day, there is no direct immediate effect of the media input on them. But there is a significant effect some days later, which we interprete as a consequence of conversation. The effect of the media on the daily users is passed on to less frequent users by interpersonal communication.     

When less family is more: Trademark acquisition,family ownership,and internationalization

This study examines the relationship between international performance and the orientation of the firm towards trademark acquisition, and discusses family ownership as a moderator of this association. We conceptualize our study along three interrelated lines of ‘openness’ i.e. openness towards external resources, openness of governance, and openness towards international markets. The empirical investigation relies on a panel data analysis over four years, and on a cross-industry sample of European listed companies consisting of 712 observations. Our outcomes reveal that the attitude of the company to enrich the brand portfolio with externally developed trademarks is positively associated with the firms’ international performance. We also find that this relationship is moderated by family ownership. “Less family is more”: we find a positive relationship of openness towards trademark acquisitions with the firms’ international performance, which decreases with the presence of a family in a dominant position.
