Disintegrating Democracy at Work
The shift from manufacturing- to service-based economies has often been accompanied by the expansion of low-wage and insecure employment. Many consider the effects of this shift inevitable. InDisintegrating Democracy at Work, Virginia Doellgast contends that high pay and good working conditions are possible even for marginal service jobs. This outcome, however, depends on strong unions and encompassing collective bargaining institutions, which are necessary to give workers a voice in the decisions that affect the design of their jobs and the distribution of productivity gains.
Doellgast's conclusions are based on a comparative study of the changes that occurred in the organization of call center jobs in the United States and Germany following the liberalization of telecommunications markets. Based on survey data and interviews with workers, managers, and union representatives, she found that German managers more often took the \"high road\" than those in the United States, investing in skills and giving employees more control over their work. Doellgast traces the difference to stronger institutional supports for workplace democracy in Germany. However, these democratic structures were increasingly precarious, as managers in both countries used outsourcing strategies to move jobs to workplaces with lower pay and weaker or no union representation. Doellgast's comparative findings show the importance of policy choices in closing off these escape routes, promoting broad access to good jobs in expanding service industries.

Engineering Trust: Reciprocity in the Production of Reputation Information
Reciprocity in feedback giving distorts the production and content of reputation information in a market, hampering trust and trade efficiency. Guided by feedback patterns observed on eBay and other platforms, we run laboratory experiments to investigate how reciprocity can be managed by changes in the way feedback information flows through the system, leading to more accurate reputation information, more trust, and more efficient trade. We discuss the implications for theory building and for managing the redesign of market trust systems.

Backtesting Expected Shortfall: Accounting for Tail Risk
The Basel Committee on Banking Supervision (BIS) has recently sanctioned expected shortfall (ES) as the market risk measure to be used for banking regulatory purposes, replacing the well-known value at risk (VaR). This change is motivated by the appealing theoretical properties of ES as a measure of risk and the poor properties of VaR. In particular, VaR fails to control for “tail risk.” In this transition, the major challenge faced by financial institutions is the unavailability of simple tools for evaluation of ES forecasts (i.e., backtesting ES). The main purpose of this paper is to propose such tools. Specifically, we propose backtests for ES based on cumulative violations, which are the natural analogue of the commonly used backtests for VaR. We establish the asymptotic properties of the tests, and investigate their finite sample performance through some Monte Carlo simulations. An empirical application to three major stock indexes shows that VaR is generally unresponsive to extreme events such as those experienced during the recent financial crisis, whereas ES provides a more accurate description of the risk involved.

Sustainable Supply Chain Management Integration: A Qualitative Analysis of the German Manufacturing Industry
Firms are increasingly integrating sustainability into their supply chain management (SCM) practices. The goal is to achieve sustainable flows of products, services, information and capital to provide maximum value to all corporate stakeholders. Prior research on SCM integration has insufficiently addressed sustainability. The objective of this research is to provide for a coherent and testable model of sustainable supply chain management integration (SSCMI). By drawing on four cases from the German manufacturing industry, we seek to identify the most important factors that enable or impede the integration of sustainability into SCM.

Consumers’ Responses to Moral Transgressions in the Fashion Industry: Comparative Insights from Western Developed and Southeast Asian Emerging Markets
Using an institutional perspective, this paper investigates how consumers in Western developed and Southeast Asian emerging markets respond to fashion brands’ moral transgressions and how consumers’ moral rationalization tendencies vary across the two markets. The study employs multimethod analyses, including cross-national secondary data from 12 countries and experimental data from 940 German and Vietnamese consumers. In a non-transgression context, the multivariate analyses show that Western developed-market consumers embrace higher ethical standards (Study 1A), tend to seek collective action against prevalent immoral behaviors in society (Study 1B), and are more critical in evaluating fashion brand ethicality than Southeast Asian emerging-market consumers (Study 2). However, in a transgression context, the moderated mediation analyses reveal that consumers largely do not differ in their direct devaluation of fashion brand ethicality and subsequent price considerations (Study 3) across six transgression scenarios (i.e., worker abuse, child labor, racist advertising, weight discrimination, climate change, and environmental pollution). Interestingly, moral rationalization processes appear to be more frequent and consequential in the Southeast Asian emerging market, while they either do not occur or are significantly weaker in the Western developed market. The results provide theoretical and practical implications for ethical business practices in the fashion industry based on market differences in regulatory frameworks, cognitive considerations, and social norms.

Collaborative research in healthcare: uncovering the impact of industry collaboration on the service innovativeness of university hospitals
In the face of the challenges of rising demand and increasing economic pressure, medical service innovations and university hospitals are becoming increasingly important as cornerstones for the continuous development of medical care. Simultaneously, increasing technological complexity, scarce funding, and resource-intensive technology development are forcing university hospitals to open up their internal innovation processes. Numerous studies have highlighted the beneficial effects of cross-sectoral collaboration on the innovation performance of industrial entities, while neglecting the perspective of academic institutions. The impact of industry collaborations on the service innovativeness of university hospitals in particular has not been addressed in previous research. Although the potential for nonlinear effects of university-industry collaborations has been discussed in research, adequate evidence, particularly in the healthcare context, has not been provided. Therefore, this study addresses the questions: (1) What is the impact of university-hospital-industry collaboration (UHIC) on the service innovativeness of university hospitals? (2) Can a nonlinear relationship between UHIC and university hospitals' service innovativeness be empirically verified? The hypotheses are tested based on an unbalanced panel data set, which combines three distinct data sources and comprises annual observations from 2011 until 2019 of all German university hospitals. The findings indicate that the UHIC intensity has a positive effect on university hospitals’ service innovativeness with a one-year time lag. Furthermore, a negative quadratic UHIC effect was found. In doing so, this study complements existing research and opens the black box by uncovering the downside of cross-sectoral collaboration for a more complete understanding of the underlying dynamics of this growing area of research, with a particular focus on university hospitals.

Knowledge proximity and firm innovation
We analyse the geographic proximity of innovative firms to different types of knowledge sources in an urban environment on a microgeographic scale. Based on a comprehensive panel data set of manufacturing and service firms in the German capital city Berlin, we investigate the characteristics of firms’ knowledge environment while differentiating by the type of innovation. Geocoded firm locations at the level of individual addresses allows us to describe the knowledge environment of firms on a very fine microgeographic scale. We find that innovative firms are located in places with higher numbers of same-sector firms, more start-ups and a higher inflow of other firms. They also locate in closer proximity to universities and research institutes. These differences decay rapidly within a few metres (50–250 m), indicating a truly microgeographic scope of knowledge sources in urban environments.
我们在微观地理尺度上分析创新企业与城市环境中不同类型知识来源的地理接近程度。基于德国首都柏林的制造和服务公司的综合面板数据集，我们在区分创新类型的基础上研究了企业知识环境的特征。单个地址层面的地理编码公司位置使我们能够以非常精细的微观地理尺度描述公司的知识环境。我们发现，创新型企业位于同行业公司数量较多、初创企业较多、其他企业流入较多的地方。它们也位于离大学和研究机构更近的地方。这些差异在数米（50-250米）内迅速衰减，表明了城市环境中知识来源地理辐射范围真实的微观特性。

Bank Bailouts and Moral Hazard: Evidence from Germany
We use a structural econometric model to provide empirical evidence that safety nets in the banking industry lead to additional risk taking. To identify the moral hazard effect of bailout expectations on bank risk, we exploit the fact that regional political factors explain bank bailouts but not bank risk. The sample includes all observed capital preservation measures and distressed exits in the German banking industry during 1995—2006. A change of bailout expectations by two standard deviations increases the probability of official distress from 6.6% to 9.4%, which is economically significant.

Industry 4.0 and Beyond: A Review of the Literature on the Challenges and Barriers Facing the Agri-Food Supply Chain
In recent years, the Industry 4.0 concept has gained considerable attention from professionals, researchers and decision makers. For its part, the COVID-19 pandemic has highlighted the importance of managing the agri-food supply chain to ensure the food that the population needs. Industry 4.0 and its extensions can address the needs of the agri-food supply chain by bringing new features such as security, transparency and traceability in line with sustainable development goals. This study aims to systematically analyze the literature to address the challenges and barriers against the application of industry 4.0 and its related technologies in the management of an agri-food supply chain. Currently, despite the large number of publications, there is no clear agreement on what Industry 4.0 is, and even less its extensions. The next revolution that includes new technologies and improves several existing technologies brings additional conceptual and practical complexity. Consequently, in this work we first determine the main components of I 4.0 and their extensions by studying the literature, and then, in the second step, define the agri-food supply chain on which I 4.0 technologies are applied. Two well-known databases—Web of Science and Scopus—were chosen to extract data for the systematic review of the literature. For the final evaluation, we identified 24 of 100 reviewed publications. The results provide an exhaustive analysis of the different I 4.0 technologies and their extensions that are applied in regards to the agri-food supply chain. In addition, we find 15 challenges that are classified into five major themes in the agri-food supply chain: technical, operational, financial, social and infrastructure. The four most important challenges identified are technological architecture, security and privacy, big data management and IoT (internet)-based infrastructure. Only a few articles addressed sustainability, which reaffirms and demonstrates a considerable gap in terms of the sustainable agri-food supply chain, with waste management being the one that has attracted the most attention. This review provides a roadmap for academics and practitioners alike, showing the gaps and facilitating the identification of I 4.0 technologies that can help address the challenges facing the efficient management of an agri-food supply chain.
