Within the field of green supply chain management (GSCM), an interest in supply chain cooperation to create sustainable competitive advantage, i.e. the collaborative paradigm, has made researchers turn their attention to information related aspects of the supply chain. This study contributes to an understanding of a suboptimal use of environmental information, which is critical for all collaborative efforts aiming at sustainable competitive advantage. The aim of this article is to describe the use of environmental information at different stages of the Swedish food supply chain. The results from this case study of the Swedish food supply chain indicate that environmental information is perceived and used differently by purchasers in the supply chain depending on where (in the supply chain) they are situated in relation to other chain actors. The main contribution of this study is the suggestion of a stage‐dependent connection between perceived environmental cost and perceived environmentally informed consumer demand, which are barriers to GSCM practice discussed in recent GSCM literature. The missing link between information sharing and (environmental) performance of supply chains is explained as distance to end‐consumer in terms of supply chain stages. Implications for GSCM practice and theory are discussed. Copyright © 2009 John Wiley & Sons, Ltd and ERP Environment. 相似文献

The Malmquist Productivity Index (MPI) suggests a convenient way of measuring the productivity change of a given unit between
two consequent time periods. Until now, only a static approach for analyzing the MPI was available in the literature. However,
this hides a potentially valuable information given by the evolution of productivity over time. In this paper, we introduce
a dynamic procedure for forecasting the MPI. We compare several approaches and give credit to a method based on the assumption
of circularity. Because the MPI is not circular, we present a new decomposition of the MPI, in which the time-varying indices
are circular. Based on that decomposition, a new working dynamic forecasting procedure is proposed and illustrated. To construct
prediction intervals of the MPI, we extend the bootstrap method in order to take into account potential serial correlation
in the data. We illustrate all the new techniques described above by forecasting the productivity index of 17 OECD countries,
constructed from their GDP, labor and capital stock. 相似文献

Are labor markets more turbulent now than thirty years ago? Most job and worker flows imply that the answer is “no”, with one exception: occupational mobility, which increased substantially in the United States. This paper remedies the lack of comparable evidence by focusing on France for the years 1982 to 2009. After correcting for various statistical biases and discrepancies that affect the measurement of occupational mobility, it documents this reallocation process overall and in different subgroups. The data reveal that, over the period considered, the fraction of workers switching occupation exhibits no trend in the aggregate because changing demographics mask increases in mobility within several age and education groups. After taking these composition effects into account, occupational mobility increased sharply in France as well. 相似文献

This paper investigates the reliability of SVARs in identifying the dynamic effects of news shocks. Using a simple but insightful model with a non-fundamental representation, we show analytically under which conditions SVARs are likely to be successful at identifying news shocks. We find that the dynamic responses to news shocks identified using a short-run restriction are biased. However, this bias is smaller if news shocks account for most of the variability of the endogenous variable and the economy exhibits strong forward-looking behavior. Our simulation experiments confirm this finding and further suggest that the number of lags in the VAR and the anticipation horizon are key ingredients for the success of the VAR setup. 相似文献

By adopting the “reasonable value” notion applied to the labor relationship as proposed by John R. Commons, I study the way in which labor legislation in China can be understood as the search for a status of employment security for rural migrant workers. However, the Chinese labor market is experiencing growth in a particular form of informal labor: delegated and temporary labor. I analyze this contradiction not as a failure of the legislation itself, but as the product of a particular institutional context which provides a way to skirt the law, and thereby diminish its effectiveness. Finally, in a non-democratic state, labor law — which has been instrumentalized and mobilized within a form of state corporatism — reveals that very significant challenges exist for building a truly secure status for employees. 相似文献

Consumers try to avoid temptation when exposed to appetizing foods by diverting their attention away from their senses (e.g., sight, smell, mouthfeel) and bodily states (e.g., state of arousal, salivation) in order to focus on their longer term goals (e.g., eating healthily, achieving an ideal body weight). However, when not including sensations in their decision‐making processes, consumers risk depleting their self‐regulatory resources, potentially leading to unhealthy food choices. Conversely, based on the concept of “embodied self‐regulation,” the suggestion is made that considering bodily states may help consumers regulate their food choices more effectively. A new model is proposed that facilitates understanding observed consumer behavior and the success or failure of self‐control in food intake. It is argued that bodily states and sensory information should be considered when modeling consumer behavior and developing health‐related advocacy and communication campaigns. The model proposed here leads to new perspectives on consumer consumption behavior and health policy research and strategies. 相似文献

Abstract We consider an investment fund whose unit value is modeled by a geometric Brownian motion. Different forms of dynamic investment fund protection are examined. The basic form is a guarantee that instantaneously provides the necessary payments so that the upgraded fund unit value does not fall below a protected level. A closed form expression for the price of such a guarantee is derived. This result can also be applied to price a guarantee where the protected level is an exponential function of time. Moreover, it is explicitly shown how the protection can be generated by construction of the replicating portfolio. The dynamic investment fund protection is compared with the corresponding put option, and it is shown that for short time intervals the ratio of the prices approaches 2. Finally, a more exotic guarantee is considered, where the protected level is a given percentage of the maximal observed fund unit value. Assuming that the protected level remains constant once the payments have started, we obtain a surprisingly simple formula for the price of a perpetual guarantee. Several numerical and graphical illustrations show how the theoretical results can be implemented in practice. 相似文献

Microfinance institutions (MFIs) lend to the poor. However, microfinance clients suffer from high interest rates, a type of poverty penalty. This article analyses the margin determinants in MFIs. A banking model has been adapted to microfinance. This model has been tested using 9-year panel data. Some factors explaining bank margin also explain MFI margin, with operating costs being the most important factor. Specific microfinance factors are donations and legal status, as regulated MFIs can collect deposits. It has also been found that MFIs operating in countries with a high level of financial inclusion have low margins. 相似文献

In this paper, we analyze how the possibility of conflict between natives and immigrants shapes income redistribution in developed democracies. This possibility can generate income redistribution towards immigrants even if they have no voting rights. We show that the threat of conflict between natives and immigrants lowers vertical income redistribution (from the rich to the poor) as the level of immigration increases. The opposite holds for horizontal income redistribution (from natives to immigrants), which increases with the level of immigration. Income inequality weakens the negative effect of immigration on vertical redistribution, but it also reduces horizontal redistribution. These theoretical predictions are consistent with the results of our empirical analysis on data from 29 European countries: larger immigrant populations are associated with more redistribution towards immigrants and lower vertical redistribution. 相似文献
