ABSTRACTThis paper addresses a road transport policy of allowing high capacity vehicles (HCVs) on the roads. The purpose is to examine the effect reduced road transport costs from HCVs can have on a modal shift. Two studies of HCV implementation in Sweden were combined. A micro-based case study modelled the distribution network of a major retailer in scenarios based on actual cost and flow data. A macro analysis was conducted of the cross-elasticity between rail and road combined with detailed price changes for lorries considering the product characteristics in different industries. The results show the long-term effects of HCVs on the modal shift for heavier, and heavier and longer vehicles. The combined approach triangulates the results and highlights the effects of logistics decision-making, transport network characteristics, and time. It emphasises linkages between modal shift and road transport efficiency, price reductions, geographical characteristics, product types, train organisation, and the capacity of HCVs. 相似文献

While an area of importance and concern to managers, international purchasing remains an under researched phenomenon, especially in the context of small and medium-sized firms. Therefore, this article presents a study of the international purchasing market entry processes of 10 industrial SMEs. The findings indicate that managers of SMEs are often reluctant to source abroad. Purchasing markets entries are generally more reactive than proactive, occurring as a consequence of needs for certain products that cannot be found domestically, high domestic costs, unsolicited opportunities and pressures from owners and customers. Nearby purchasing markets typically dominate throughout the process unless cost savings motivate firms to explore more remote markets. 相似文献

Regulating a Polluting Firm Under Asymmetric Information 总被引:1,自引:3,他引:1
This paper reinterprets the Laffont-Tirole model of regulation under asymmetric information to cover the case of pollution control. The asymmetry of information concerns the firm's cost of lowering its pollution. The regulator has three objectives: Ensuring an efficient abatement level, generating 'green taxes' and securing the survival of the firm. We show that when optimal abatement is important relative to tax generation, the regulator cannot use the policy of offering the firm a set of linear tax schemes from which to choose. By contrast, this policy is optimal in the Laffont-Tirole model under certain not very restrictive assumptions. We proceed to establish a simple rule for when to shut-down inefficient types. In an example with specific functional forms, we derive the optimal tax function both analytically and graphically. We show the effect on the optimal tax system of a change in a technological parameter. 相似文献

It has recently been argued that giving is spontaneous while greed is calculated (Rand et al., in Nature 489:427–430, 2012). If greed is calculated we would expect that cognitive load, which is assumed to reduce the influence of cognitive processes, should affect greed. In this paper we study both charitable giving and the behavior of dictators under high and low cognitive load to test if greed is affected by the load. This is tested in three different dictator game experiments. In the dictator games we use both a give frame, where the dictators are given an amount that they may share with a partner, and a take frame, where dictators may take from an amount initially allocated to the partner. The results from all three experiments show that the behavioral effect in terms of allocated money of the induced load is small if at all existent. At the same time, follow-up questions indicate that the subjects’ decisions are more impulsive and less driven by their thoughts under cognitive load. 相似文献

Based on firm level data from 16 Sub-Saharan African countries we show how three different measures of credit constraints lead to three different estimates of gender differences in manufacturing firms’ credit situation. Using a perception based credit constraint measure female owned firms appear relatively more constrained than male owned firms. Using formal financial access data we find no gender effect. Finally, using direct information on credit constraints, male owned small firms appear disadvantaged. Furthermore we show a strong size gradient in the gender gap for the two measures for which we find significant gender differences. 相似文献

Packaging affects the logistical and environmental efficiency of supply chains. The purpose is to increase knowledge of the current state, trade-offs and improvement potential of packaging logistics in supply chain practice. The research is based on 22 cases, each of which consists of supply chain mapping and structured interviews with three supply chain actors (manufacturer, distributor and retailer). The paper identifies and explains improvement areas, trade-offs and gaps in packaging systems from a supply chain perspective for the whole packaging system, each packaging level and each actor. The results highlight a supply chain potential of better incorporating the packaging system requirements from actors not responsible for developing or selecting packaging. The paper discusses models for cost and benefit sharing and for identification and decision-making about trade-offs in packaging systems. Companies should collaborate, apply an integrated approach and find new approaches to integrate customers and suppliers into the packaging development process. 相似文献

Psychological studies are frequently cited in the business and finance literature to bolster claims that various kinds of economic disasters, from the large proportion of start-ups that quickly go out of business to the exaggerated confidence of financial investors, can be attributed to overconfidence. This article reviews some of the problems associated with concluding that people overestimate the accuracy of their judgments based on observed overconfidence measured as the difference between mean subjective probability and proportion correct. Methodological and statistical artifacts, such as regression, can explain many of the observed instances of apparent overconfidence. 相似文献
