One of the most robust stylized facts in macroeconomics is the forecasting power of the term spread for future real activity. We propose a possible causal mechanism for the forecasting power of the term spread, deriving from the balance sheet management of financial intermediaries and the “risk‐taking channel of monetary policy.” Monetary tightening leads to the flattening of the term spread, reducing net interest margin and credit supply. We provide empirical support for the risk‐taking channel.  相似文献

The centrality of cross‐functional integration (CFI) to supply chain theory and practice has long been recognized. Yet researchers continue to struggle with consistently defining or measuring the CFI construct, thus limiting the utility of CFI research. This research develops (1) a comprehensive definition of CFI that synthesizes previous supply chain research and (2) a valid set of scale items that measure the conceptual domain outlined by this definition. The goal is to build a common foundation for extending knowledge on CFI's antecedents and consequences, and ultimately to improve scholars’ ability to guide a broader practitioner community still struggling to achieve integration in their organizations.  相似文献

This study investigated the training effect of multiple job holding on the activity of main jobs. First, we developed a dual-labor supply model by adding the training effect of working second jobs. The theory showed that workers with unconstrained hours hold second jobs when they develop skills via the experience of second jobs. To verify the hypotheses from the theoretical model, the causal relationship between holding a second job and the wage rate of a main job was estimated using the Keio Household Panel Survey. Difference generalized method of moments was adopted to remove time-invariant individual effects and endogenous bias. Moreover, the estimations showed heterogeneity of main jobs in terms of length of working hours, tasks, and job turnover. Full-time workers engaged in intelligent tasks and those who did not change their jobs secured training effects from second jobs but only when the comparison group was the workers allowed to hold second jobs by their employers. It was presumed that employers paid to restrict employees’ activities. On the contrary, part-time workers engaged in physical tasks were exhausted by second jobs, which decreased the wage rate of their main jobs.  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

在2020年暴发的新冠肺炎疫情中,中美本应借机缓和前期的贸易冲突危机,但美国不仅没有缓和与中国的关系,反而从医疗产品进口、供应链转移、舆论战等方面,加大与中国的分歧,这背后的原因包括:美国对中国的战略打压、借机转移国内矛盾、中美发展模式之争,以及科技竞争加剧等。为此,本文建议中美之间增进相互信任,中国应谨防陷入美国的话语陷阱,专注于解决自身国内问题,以及加强底线思维,做好最坏打算。  相似文献

A demand function of online shopping supply chain based on online-to-offline (O2O) fusion degree is proposed by considering the low-carbon awareness of online shoppers in view of the low-carbon decision making of supply chain in combination with the O2O operation background. On this basis, a low-carbon decision-making model based on online stores and their suppliers is established, and the application of the model is analyzed. Results show that the promotion of low-carbon operation is efficient when the consistency of online and offline operations of online stores and their suppliers is high. In addition, the decision making considering the cost of carbon information release is highly conducive to improving the low-carbon awareness of online shoppers if the low-carbon level of online shopping goods is lower than the low-carbon standard. Accordingly, the low-carbon operation of online shopping supply chain will be promoted.  相似文献

Managing the distribution of fuel in theater requires Army fuel planners to forecast demand at the strategic level to ensure that fuel will be in the right place, at the right time, and in the amounts needed. This work presents a simulation approach to forecasting that accounts for the structure of the supply chain network when aggregating the demand of war fighters across the theater over the forecasting horizon. The resulting empirical distribution of demand at the theater entry point enables planners to identify forecast characteristics that impact their planning process, including the amplitudes and temporal positions of peaks in demand, and the estimated lead time to the point of use. Experimentation indicates that the forecasts are sensitive to the pattern of war fighter demand, the precise structure of the in-theater supply chain network, and the constraints and uncertainty present in the network, all of which are critical planning considerations.  相似文献
