Is the Erosion Thesis Overblown? Alignment from Without in Germany

It is sometimes alleged that collective bargaining coverage in Germany is understated because uncovered firms “orient” themselves toward sectoral agreements. In fact, although orientation has grown as sectoral bargaining has declined, their joint frequency has fallen. Further, where orientation occurs at firms that leave a sectoral agreement, it provides only partial compensation. The small deficits involved, in conjunction with some indirect evidence on joiners, suggest some modest attenuation of the undoubted decline in collective bargaining.     

Rationality in supplier selection decisions: The effect of the buyer's national task environment

Our study sheds light on two fundamental questions in supply management: First, does adherence to highly rational decision processes help buyers make better supplier selection decisions? Second, is the influence of procedural rationality on decision effectiveness moderated by buyers’ (differently dynamic) task environments? We empirically test these questions using a sample of 150 supplier selection decisions taken in China and 150 decisions taken in Germany, countries that expose buyers to dynamic decision environments and stable decision environments, respectively. Our findings suggest that the influence of decision process rationality is stable across decision makers’ task environments. Both in China and in Germany, such process rationality is positively related with higher decision quality, and no significant differences in relationship strengths emerge between the two country samples.     

Inference on impulse response functions in structural VAR models

Skepticism toward traditional identifying assumptions based on exclusion restrictions has led to a surge in the use of structural VAR models in which structural shocks are identified by restricting the sign of the responses of selected macroeconomic aggregates to these shocks. Researchers commonly report the vector of pointwise posterior medians of the impulse responses as a measure of central tendency of the estimated response functions, along with pointwise 68% posterior error bands. It can be shown that this approach cannot be used to characterize the central tendency of the structural impulse response functions. We propose an alternative method of summarizing the evidence from sign-identified VAR models designed to enhance their practical usefulness. Our objective is to characterize the most likely admissible model(s) within the set of structural VAR models that satisfy the sign restrictions. We show how the set of most likely structural response functions can be computed from the posterior mode of the joint distribution of admissible models both in the fully identified and in the partially identified case, and we propose a highest-posterior density credible set that characterizes the joint uncertainty about this set. Our approach can also be used to resolve the long-standing problem of how to conduct joint inference on sets of structural impulse response functions in exactly identified VAR models. We illustrate the differences between our approach and the traditional approach for the analysis of the effects of monetary policy shocks and of the effects of oil demand and oil supply shocks.     

Overcoming the main barriers in initiating and using purchasing-BSCs

The Balanced Scorecard (BSC), as a strategic management and control tool with an integrated set of leading and lagging performance measures, can secure successful implementation of purchasing strategies. However, the quality of the BSC itself as well as the effectiveness of the process to set up, implement, and use the BSC are crucial. Recognizing the growing importance of the purchasing-BSC (P-BSC) combined with the problems companies are facing, the authors emphasize the necessity for a better management process for purchasing strategies, introduce the P-BSC concept as a means to improve implementation success, and study the main barriers companies are facing when they initiate and use P-BSCs. This study and the recommendations how to overcome these barriers are based on seven in-depth case studies which derived from an action research project with European multinational firms.     

Revisiting the Relevance of International Trade Theory

Probably one of the most controversial contributions to the literature of international trade theory was offered by the late social economist John Culbertson. In his view, low wage competition among corporations in a world characterized by capital mobility and massive trade deficits undermines the foundation trade theory based on David Ricardo’s celebrated notion of comparative advantage. Instead, there are several good reasons to believe that international trade with China, India, Vietnam, etc. will be governed by absolute advantage. The current essay is dedicated to the virtually ignored work of Culbertson, and it is meant as an invitation for social economists to critically evaluate the argument and in the process make an attempt to point out where it goes wrong.     

What are the top five journals in economics? A new meta-ranking

We construct a meta-ranking of 277 economics journals based on 22 different rankings. The ranking incorporates bibliometric indicators from four different databases (Web of Science, Scopus, Google Scholar, and RePEc). We account for the different scaling of the bibliometric indicators by standardizing each ranking score. We run a principal component analysis to assign weights to each ranking. In our meta-ranking, the top five journals are given by: Quarterly Journal of Economics, Journal of Financial Economics, Journal of Economic Literature (JEL), Journal of Finance, and Econometrica. Additionally, leaving out the JEL as a survey journal and the finance journals in our top 10 list we confirm the perceived top five journals in the economics profession.     

Reference Publication Year Spectroscopy (RPYS) with publications in the area of academic efficiency studies: what are the historical roots of this research topic?

In this study, we explore the historical roots of the relatively new topic in scientometrics of academic efficiency assessments. We are interested in the contributions of researchers from the past which have been revealed as important for the topic in the long run. The technique of Reference Publication Year Spectroscopy (RPYS) has been recently introduced which is based on the analysis of the frequency with which references are cited in the publications of a specific research field (here: academic efficiency assessments). The study is based on papers conducted for a systematic review of empirical articles on technical efficiency in academic research production: 60 papers (published between 1992 and 2012) and 1314 cited references. Results indicated that 5 peaks are clearly identifiable until 2000. They correspond, respectively, to the years 1957 (The founding article of Farrell), 1978 (Proposition of a new promising approach: the Data Envelopment Analysis (DEA) by Charnes et al.), 1988 (Research-teaching multi-output model and integration of quality indicators), 1990 (DEA in the service of Research Assessment Exercise) and 1997 (Introduction of weight restrictions in DEA). The peaks are described with the underlying publications and recent developments (since 2000) in the area of academic efficiency studies are outlined.     

The Coevolution of Relationship Dominant Logic and Supply Risk Mitigation Strategies

How and why do risk mitigation strategies evolve? And which resources are needed for engaging in such changes? This paper contributes to the understanding of risk management in supply chains by developing theory about the interplay between supply risk mitigation strategies and the purchasing team's relationship dominant logic (RDL), which we define as the purchasing team's orientation toward and shared cognitive map of the management of its supply chain relationships. Specifically, we propose that RDL and supply risk mitigation strategies are fundamentally intertwined. Following a Straussian approach to grounded theory, this study analyzes data generated from the purchasing teams of Western green‐tech firms trying to mitigate supply risk for technically indispensable rare earth metals from China. Our findings from this context that is heavily shaped by state‐influenced supply chain members show that the firms chose their mitigation strategies in line with their RDL. Human capital, social capital, and financial capital seem to moderate the link between RDL and mitigation strategies. We link our findings with the strategic management literature in deriving theoretical propositions concerning these relationships.     

Works Councils and Plant Closings in Germany

This paper is the first study to investigate the impact of workplace representation on plant closings in Germany, using data from a nationally representative establishment panel. Across all establishments in our sample, we find evidence of a positive association between works council presence and plant closings. There is the contrary suggestion that industry‐wide collective bargaining plays a neutral to benign role. As for the interaction between collective bargaining and workplace representation, this appears strongest for establishments with fewer than 50 employees: such plants are much more likely to close if they have a works council and are not covered by a collective agreement.
