In the face of declining business and growing pressures from low-cost competitors, many business-to-business (B2B) manufacturers have moved from their previously successful product-centric strategies to more service-oriented business models. Yet despite their substantial investments in services, firms fail to understand the performance ramifications of these offerings. With a longitudinal data set (2001–2016) of 227 B2B manufacturers listed in the S&P 1500 index, this study disentangles the simultaneous effects of financial-based mechanisms that link the service ratio (i.e., share of a firm's revenue generated from selling services) to firm value. The findings reveal significant trade-offs across these mechanisms. Although the service ratio monotonously boosts sales growth, it has U-shaped curvilinear relationships with profitability and earnings volatility. These effects also depend on industry- and firm-level factors. Industry maturity positively moderates the effects of the service ratio on sales growth and profitability. However, business scope has an adverse effect on the service ratio–profitability relationship. Finally, industry turbulence negatively moderates the effect of services on earnings volatility. 相似文献

Using elicited expectations of future gross salaries, we evaluate characteristics causing German students to make larger or smaller estimation errors. While students seem to underestimate actual salaries by 18 percent, we show that these errors are highly attributable to misconceptions of the progressive income tax. Developing a suitable adjustment procedure, we correct students’ estimates and find that errors decline by 12 percentage points. Conducting regression analyses, we reveal strong connections with students’ age, gender, work experience, secondary school track, and knowledge about student loans. These results change notably if not controlling for students’ misconceptions of the tax system. 相似文献

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that – due to their position in global value chains – certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers. 相似文献

Additive manufacturing (AM) appears to be a particularly attractive use case for blockchain. This research combines inductive in‐depth interviews with the Delphi method to explore what potentials blockchain technology in AM creates, which adoption barriers firms need to overcome, and how supply chains will be affected by the integration of these two potentially disruptive technologies. The results suggest opportunities that are related to intellectual property (IP) rights management, the monitoring of printed parts throughout their lifecycle, process improvements, and data security. The most important barriers for blockchain adoption in AM are an absence of blockchain‐skilled specialists on the labor market, missing governance mechanisms, and a lack of firm‐internal technical expertise. By addressing important limitations of AM, blockchain is expected to improve the competitiveness of AM in parts’ production, catalyzing the trend toward more decentralized manufacturing resulting in more agile, resilient, and flexible supply chains and reduced logistics costs. Beyond that, blockchain‐based AM platforms are expected to enhance supply chain visibility, drive supply chain digitalization, support supply chain finance, and contribute to the emergence of shared factory systems. 相似文献

A partir de estimaciones de la OIT del empleo en las cadenas mundiales de suministro, se estudia el impacto de las barreras al comercio de bienes y servicios sobre los empleos nacionales. El análisis empírico confirma las predicciones de un modelo teórico calibrado con datos de la WIOD para 2000 y 2011. Las barreras al comercio de bienes y servicios tienen un impacto transfronterizo sobre los empleos del sector directamente afectado y efectos indirectos sobre otros sectores que aumentan con el tiempo. La creciente interconexión entre países y sectores en las cadenas mundiales de suministro implica que las políticas comerciales pueden tener importantes efectos sobre los mercados de trabajo de otros países. 相似文献

Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in recent years, digital platforms have turned into the most important actors in the global sharing economy, turning global corporations, such as AirBnB, Booking, or TripAdvisor into intermediaries controlling and profiting from most transactions. Focused on accommodation, this paper conceptualizes the sharing economy in comparison to the wider collaborative economy, and discusses its social, economic, environmental, and political impacts in comparison to the sustainable development goals. It concludes that the sharing economy has great potential to make very significant contributions to sustainability, though the model is increasingly being replaced by the collaborative economy, which performs as an extension and acceleration of neoliberal economic practices. 相似文献

The German economy experiences a boom period. The leading economic research institutes upgrade their economic balance for 2017 to a growth rate exceeding two per cent and their forecasts for 2018 are equally positive. This optimism is widespread despite the UK’s exit from the EU, the protectionist tendencies and the difficult coalition-building in Germany. Technological innovations look ahead: manufacturing industry and trade sector have to react to digital transformation — i.e. electro-mobility, autonomous driving, the use of artificial intelligence and the spread of online trading. 相似文献

A framework for the detection of change points in the expectation in sequences of random variables is presented. Specifically, we investigate time series with general distributional assumptions that may show an unknown number of change points in the expectation occurring on multiple time scales and that may also contain change points in other parameters. To that end we propose a multiple filter test (MFT) that tests the null hypothesis of constant expectation and, in case of rejection of the null hypothesis, an algorithm that estimates the change points.The MFT has three important benefits. First, it allows for general distributional assumptions in the underlying model, assuming piecewise sequences of i.i.d. random variables, where also relaxations with regard to identical distribution or independence are possible. Second, it uses a MOSUM type statistic and an asymptotic setting in which the MOSUM process converges weakly to a functional of a Brownian motion which is then used to simulate the rejection threshold of the statistical test. This approach enables a simultaneous application of multiple MOSUM processes which improves the detection of change points that occur on different time scales. Third, we also show that the method is practically robust against changes in other distributional parameters such as the variance or higher order moments which might occur with or even without a change in expectation. A function implementing the described test and change point estimation is available in the R package MFT. 相似文献

Learning is often a central element of tourism. Tourists can learn actively, i.e. with a specific purpose, as well as passively through the comparison of values, norms and customs. It has been argued that travel supports active learning that has positive outcomes for sustainability, for instance, in the context of conservation. Yet, the complexity of active and passive learning processes and their outcomes for environmental sustainability and sustainable lifestyles remain insufficiently understood. Against this background, the paper discusses selected learning outcomes for transportation (air travel), accommodation (hotels) and activities (theme park visits). Findings suggest that “desirable” learning (defined as pro-sustainable development learning) in tourism may be very limited, while in particular, passive learning processes which redefine social norms frequently have outcomes that are largely detrimental to sustainable lifestyles. They include forms of moral licensing, the diffusion of responsibilities as well as the attenuation of the negative consequences of travel. Given the economic, social and cultural importance of tourism vís-a-vís its global implications for environmental sustainability, learning outcomes in tourism deserve to be studied in greater detail, while strategies need to be devised to enhance sustainable learning effects. 相似文献
