In order to control the time to market and manufacturing costs, companies produce and purchase many parts and components before receiving customer orders. Consequently, demand forecasting is a critical decision process. Using modular product design and super bills of materials are two effective strategies for developing a reliable demand forecasting process. They reduce the probability of stockouts in diversified production contexts. Furthermore, managing and controlling safety stocks for pre-assembled modules provide an effective solution to the problem of minimizing the effects of forecast errors. This paper develops, evaluates, and applies innovative cost-based analytical models so that the optimal safety stock of modular subassemblies and components in assembly to order and manufacturing to order systems, respectively, can be rapidly quantified. The implementation of the proposed models in two industrial case applications demonstrates that they significantly reduce the safety stock inventory levels and the global logistical cost. 相似文献

It is generally acknowledged that the cuts in government funding for research implemented in several European countries will induce academic researchers to increase their interaction with non academic entities to promote the acquisition of external funding for research. Indirectly this implies that there will be a shift in the focus of academic scientific activity from basic to applied research via private research contracts and consultancy work. The aim of our paper is to assess the extent of the trade-off between basic research and applied activity in academic research departments. We use data for the universe of Italian academic departments over the period 2006–2011 and estimate whether increased applied activity is substituting or complementing basic research activity. We provide empirical evidence of a strong substitution effect for life sciences departments and, to a lesser extent, for engineering and technology departments, while there does not seem to be evidence of a substitution effect for departments whose scientific activity revolves around basic science. 相似文献

The aim of the present study is to examine the role of ethical dimensions and product personality in the purchasing intention
of organic food products. The Prospect method (Caprara et al. in Test Psicomet Metodol 7(3–4):113–128, 2000), which integrates the Five factors model of personality (cf. Digman in Annu Rev Psychol 41(1):417–440, 1990) and the Theory of planned behavior (Ajzen in Organ Behav Hum Decis Process, 50(2):179–211, 1991) extended to an ethical dimension, was employed, by using a Structural Equation Modeling approach. Results showed that moral norms—i.e., personal beliefs regarding what is right or wrong (Parker et al. in Br J Soc Psychol, 34(2):127–137, 1995)—can be considered the main motivator of purchasing intention, and they are, in turn, affected by subjective norms and product personality traits of Naturalness and Authenticity. Marketing implications for firms operating in the organic food industry are discussed, in their intent to shift from a “niche”
market to a broader diffusion of these products. 相似文献

The erosion of preferences due to multilateral tariff reductions is a long-standing concern for many developing countries. This paper focuses on the erosion of the preferences granted by the EU in the rice industry. Since 2004 there has been a sharp decrease in border protection for the EU rice industry. Because the EU grants trade preferences to a considerable number of rice exporting developing countries, the reform implied preference erosion as well. By addressing the impact of preference erosion on developing countries rice exports to the EU, this paper contributes two original insights to the literature: first, by proposing a new empirical approach to compute the preference margin when tariff rate quotas are in force which is based on the assumption of the existence of fixed costs and economies of scale in international trade; second, by estimating the trade elasticities of preferences by means of a dynamic panel gravity equation to deal with the issues of endogeneity of preferences and persistency in bilateral trade flows. The results show that the way preference margins are calculated matters significantly when assessing the existence and extent of their erosion and the values of trade elasticities. Finally, the estimations highlight the fact that the impact of preferences is still very strong for some of the countries concerned. 相似文献

The paper presents the results of an extensive study on the determinants of customer satisfaction for a retail bank. In doing so, it uses a revised version of the traditional analyses based on derived measures of attribute importance. The need for a revised methodology is prompted by the insights of the two- and three-factor theories of customer satisfaction, such as Kano's framework. Indeed, the evidence from 5000 customers of a prominent Italian bank confirms a non-linear and asymmetric relationship between attribute performances and overall customer satisfaction. The results from both a traditional and our revised approach are compared. While this approach can be applied across different industries, it should not be assumed that the numerical results presented in the paper apply to contexts with substantially different underlying characteristics. General trends and implications for banking services are reported in the conclusions. 相似文献

Under numerical fiscal rules, such as those underpinning EMU,governments have strong temptations to use accounting tricksto meet the fiscal constraints. Given these political incentives,fiscal variables that in the past were regarded as a mere residualacquire a strategic role. This is the case of the so-calledstock-flow adjustment (SFA) which reconciles deficit and debtdevelopments. We develop a simple theoretical model where deficitsand two distinct SFA components (one that could be used to reducethe deficit figures and the other to impact debt figures instead)are determined as a result of a constrained optimisation byfiscal authorities. Econometric evidence provides results consistentwith the model findings. The SFA component related to the purposeto hide deficits rises with the recorded deficit, while thesales of financial assets designed to keep the debt under controlrise with both debt and deficit. When deficits are in excessof the 3 percent limit, accounting gimmicks become more sensitiveto the size of deficits. The SGP per se does not appear to increasethe extent to which higher deficits trigger more accountinggimmicks. However, the SGP seems associated with a more intenseuse of accounting gimmicks irrespective of the level of deficit.Such accounting practices have greatly contributed to the lossof credibility of Economic and Monetary Union's fiscal rules.If properly implemented, the reformed Pact, which stresses durableadjustment and long-run sustainability, should help curb suchperverse incentives.

Why do we observe some developing countries objecting to the prospect of a Multilateral Agreement on Investment (MAI), even though they have been keen to liberalize investment in preferential agreements in recent years? In this paper, we analyze the issue of MAI implementation and assess the welfare consequences of such kind of agreements. In our model, participation to MAI involves a tradeoff between less rent extraction from multinational firms (MNEs) and more abundant FDI inflows. At equilibrium, either all countries enter MAI, or all countries stay out, or only some of them enter. Coordination problems may induce multiple equilibria: the three types of equilibria may coexist. So, the implementation of MAI may depend not only on structural factors but also on the general “political climate.” When all countries join MAI, world welfare is maximized because this minimizes the hold‐up problem faced by MNEs and stimulates investment. However, in an asymmetric world, welfare gains are not guaranteed for all countries. 相似文献

This paper addresses the issue of how to estimate by contingentvaluation methods the maximum price consumers are willing topay when a new quality is available for a market good for whichquantity adjustments are possible. We argue that current practice,which typically does not specify a quantity when asking consumersthe price they are willing to pay for a new quality product,fails to identify prospective consumers' behaviour when theyare free to adjust the quantity purchased. Theoretical modelsare discussed for assessing the maximum price consumers arewilling to pay in these cases, and econometric approaches toaddress these situations are discussed. 相似文献

In this paper, we carry out an econometric analysis on the adoption and effective use of Information and Communication Technologies (ICTs) among a sample of Italian SMEs. An important result is that, in order to understand the main factors that drive SMEs to the adoption of ICTs, it is useful to divide the available technologies according to a taxonomy based on their typical function. Along with general-use ICTs (e-mail and Internet access), we identify two groups of technologies (labelled production-integrating and market-oriented ICTs) the use of which is associated with different firm characteristics. In both cases, however, the availability of highly educated workers turns out to be a key factor. Policy implications are also discussed. 相似文献
