The phenomenon of key supply management (KSM) in business companies is far less investigated than the phenomenon of key account management (KAM) which beneficiates, both in practice and in an academic context, from a growing interest. This article is based on the empirical analysis of a sample of 10 international companies which have recently launched KSM programmes or are currently working on launching such programs. It examines the difficulties these companies come up against when implementing such programmes and proposes to organize these difficulties around three dimensions: 1) the difficulties in implementing real supplier portfolio approaches; 2) the narrow view of value co-creation with suppliers, and 3) the persistent lack of integration of the purchasing function with other internal functions within the company. The conclusion of the article is that KSM is far from being a mere symmetric phenomenon of KAM. Several implications are then discussed in relation to the implementation of KSM programmes within companies. 相似文献

Why is invention strongly positively correlated with parental income not only in the United States but also in Finland, which displays low income inequality and high social mobility? Using data on 1.45 M Finnish individuals and their parents, we find the following: (i) the positive association between parental income and off-spring probability of inventing is greatly reduced when controlling for parental education; (ii) instrumenting for the parents having an MSc degree using distance to nearest university reveals a large causal effect of parental education on offspring probability of inventing; and (iii) the causal effect of parental education has been markedly weakened by the introduction in the early 1970s of a comprehensive schooling reform. 相似文献

We empirically study the role of assets held by women in the creation of household wealth using data from rural India. We design a streamlined model of intrahousehold project funding where moral hazard frictions between spouses and women's asset control are the main ingredients. As predicted by the model, the data show that household asset accumulation depends on women's asset control in a non-monotonic way. Results indicate no presence of multiple equilibrium poverty traps, but do show that exogenous negative shocks will trigger assets aggregation within households where both spouses are present. This resilience mechanism is, however, not found in female headed household as these households have a monotonic relationship between women's wealth control and asset creation. We thus argue that policies to support women's empowerment need to distinguish women based on their individual wealth levels and headship status to enhance household well-being in remote Indian communities. 相似文献

Interest: This research analyses the influence of situations on salespersons’ gestures and behaviors. This research contributes to this underresearched field by exploring the impact of stressful versus nonstressful situations on salespersons’ personal behavior.Methods: This research is based on 1,205 gestures observed during 382 sales calls that averaged 11 minutes with 382 salespersons. Half were in stressful situations, and half were in nonstressful situations. This study focuses on pharmaceutical products (drugs) in the medical field, with 95 doctors, 6 judges, 304 average performing salespersons, 39 high performers, and 39 low performers. This study shows how salespersons’ behaviors vary depending on stressful and nonstressful situations. This research also articulates a new field of sales research that is understudied by researchers and suggests new training trends in sales management.Objective: The objective is to answer questions such as “Does stress influence salespersons’ behavior, and what are the gestures most affected by such situations?” To examine the effects of training on gestures, an experiment with 97 salespersons was conducted during a sales training session. This experiment measured whether salespersons trained on gestures behaved differently than those who were untrained.Results: In general, stressful or nonstressful situations caused real differences in gestural behavior. In particular, the best salespersons performed the largest number of gestures during stressful situations. For example, stressful situations increased the mechanical or emotional gestures in leg movements or the number of glances. 相似文献

This paper examines the relative well‐being of Portuguese immigrants in Luxembourg by looking at indicators of material deprivation. We document material deprivation differences between immigrants and nationals—the “deprivation gap”—and measure the extent to which income differentials (and other sociodemographic differences) explain this gap using a combination of non‐parametric methods and a versatile graphical device. We find a large and significant deprivation gap against Portuguese immigrants, whatever the indicator considered. The extent to which the gap is merely a reflection of differences in income, however, depends on what deprivation items are taken into consideration. Income differences almost fully account for material deprivation differences when the latter is measured using the items included in the official EU social indicator of material deprivation. Inclusion of housing condition indicators mitigates this relationship and we then find compelling evidence that the deprivation gap is not entirely accounted for by income differentials. 相似文献

This article examines the efficacy of a ‘defense in participations’ policy consisting of competitors acquiring cross‐equity participations within the same industry to prevent hostile takeovers. This defense in participations strategy provides disincentive for raiders as partial ownerships increase market power of competitors and then reinforce the ‘outsider effect’. Also, we find conditions for a general result, which state that takeovers are less profitable in an industry with participations rather than in an industry without any capital links. We provide information to regulators about the positive social impact of cross participations in the context of mergers and expose an economic dilemma between a ‘laissez‐faire’ and an interventionist approach.

This article assesses the impact of armed conflict on the drinking water service of Basrah from 1978 to 2013 through an ‘urban warfare ecology’ lens in order to draw out the implications for relief programming and relevance to urban studies. It interprets an extensive range of unpublished literature through a frame that incorporates the accumulation of direct and indirect impacts upon the hardware, consumables and people upon which urban services rely. The analysis attributes a step‐wise decline in service quality to the lack of water treatment chemicals, lack of spare parts, and, primarily, an extended ‘brain‐drain’ of qualified water service staff. The service is found to have been vulnerable to dependence upon foreign parts and people, ‘vicious cycles’ of impact, and the politics of aid and of reconstruction. It follows that practitioners and donors eschew ideas of relief–rehabilitation–development (RRD) for an appreciation of the needs particular to complex urban warfare biospheres, where armed conflict and sanctions permeate all aspects of service provision through altered biological and social processes. The urban warfare ecology lens is found to be a useful complement to ‘infrastructural warfare’ research, suggesting the study of protracted armed conflict upon all aspects of urban life be both deepened technically and broadened to other cases. 相似文献

The promotion system for French academic economists provides an interesting environment to examine the promotion gap between men and women. Promotions occur through national competitions for which we have information both on candidates and on those eligible to be candidates. Thus, we can examine the two stages of the process: application and success. Women are less likely to seek promotion, and this accounts for up to 76 percent of the promotion gap. Being a woman also reduces the probability of promotion conditional on applying, although the gender difference is not statistically significant. Our results highlight the importance of the decision to apply. 相似文献

How does the exposure to product market competition affect the investment horizon of firms? We study if firms have an incentive to shift investments toward more short‐term assets when exposed to tougher competition. Based on a stylized firm investment model, we derive a within‐firm estimator using variation across investments with different durabilities. Exploiting the Chinese World Trade Organization (WTO) accession, we estimate the effects of product market competition on the composition of US firm investments. Firms that experienced tougher competition shifted their expenditures toward investments with a shorter durability. This effect is larger for firms with lower total factor productivity. 相似文献

We characterize prior‐by‐prior Bayesian updating using a model proposed by Gilboa, Maccheroni, Marinacci, and Schmeidler (2010) that jointly considers objective and subjective rationality. These rationality concepts are subject to the Bewley unanimity rule and maxmin expected utility, respectively, with a common set of priors and the same utility over consequences. We use this setup with two preference relations to develop a novel rationale for full Bayesian updating of maxmin expected utility preferences. 相似文献
