A buyer's perspective on collaborative versus transactional relationships

This research examines collaborative and transactional relationships in buying firms to determine whether collaborative relationships offer greater benefits than transactional relationships, and to ascertain which relational factors drive satisfaction and performance for both collaborative and transactional relationship types. Factor analysis, t-tests and step-wise regression were used to analyze data from a survey of buying firms. Results show that collaborative relationships offer higher levels of satisfaction and performance than transactional relationships. Satisfaction factored into two separate constructs: satisfaction with the relationship and satisfaction with the results. Of the relational factors examined, trust is the most important predictor of performance and satisfaction with the relationship regardless of the type of relationship examined.     

Investigating the influence of velocity performance on satisfaction with third party logistics service

The Third Party Logistics (3PL) service industry is characterized by customer relationships that can extend over several years, involving multiple instances of service delivery. When services are delivered on an ongoing basis, customers are able to not only evaluate positional (current) performance, but also velocity (rate at which the service changes) performance. This research presents findings from an empirical study utilizing an online survey of 3PL customers to examine the influence of these two types of performance on 3PL service satisfaction. Environmental moderators including market turbulence and competitive intensity are also examined, and results indicate that velocity performance is a more important driver of satisfaction when customers operate in industries characterized by high market turbulence. The findings suggest that 3PL service providers should implement velocity performance metrics, especially for customers operating in rapidly changing environments, and use velocity performance information during the sales process and customer negotiations.     

Supplier traits for better customer firm innovation performance

Previous research on embedded ties with suppliers in an innovation context has ignored the need for customer firms to assess and select suppliers on the basis of market orientation strategies and relationship marketing attributes. To address this void, this study investigates the effects of suppliers' downstream customer orientation and supplier-customer homophily (i.e., similarity of the supplier and the customer) on the customers' innovation performance. Data pertaining to new product development projects with contributions from supplier firms was collected on both sides of the supplier-customer dyad. The analysis shows that downstream customer orientation and supplier-customer homophily have a significant impact on the customer firms' new product efficiency (i.e., project cost and project speed) and new product effectiveness (i.e., innovativeness), which in turn positively influence new product performance in terms of profitability, market share, and growth.     

Survival and dissolution of exporter relationships with importers: A longitudinal analysis

The primary purpose of this paper is to extend knowledge about the survival or dissolution of interorganizational exporter/importer relationships. Based on a conceptual framework, this paper presents a longitudinal analysis of data to explore the relationships between trust, economic performance and the outcome of survival/dissolution of a business-to-business relationship. In addition, two interactions are presented that involve business distance on the outcome of the survival/dissolution of a business-to-business relationship. The results show a significant positive relationship of both trust and economic performance on survival. Findings also reveal a significant negative interaction between business distance and trust on survival. Finally, there is only a marginally significant negative interaction between business distance and economic performance on survival.     

Theory and practice of monetary policy

Summary. We consider an optimally managed renewable resource with stochastic non-concave growth function. We characterize the conditions under which the optimal policy leads to global extinction, global conservation and the existence of a safe standard of conservation. Our conditions are specified in terms of the economic and ecological primitives of the model: the biological growth function, the welfare function, the distribution of shocks and the discount rate. Our results indicate that, unlike deterministic models, extinction and conservation in stochastic models are not determined by a simple comparison of the growth rate and the discount rate; the welfare function plays an important role.Received: 20 October 2004, Revised: 28 February 2005, JEL Classification Numbers: D90, O11, O41, Q32.Santanu Roy: Correspondence toResearch on this paper was completed when the second author visited Cornell University in July, 2003.

Differences in exchange rate pass-through in the euro area

This paper focuses on the pass-through of exchange rate changes into the prices of imports made by euro area countries originating outside the area. Using data on import unit values for 13 different product categories for each country, we estimate industry-specific rates of pass-through across and within countries for all euro members. In the short-run, pass-through rates differ across industries and countries and are less than one. In the long-run neither full pass-through nor equality of pass-through rates across industries and countries can be rejected. Differences exist across euro area countries in the degree that a common exchange rate movement gets transmitted into consumer prices and costs of production indices. Most of these differences in transmission rates are due to the distinct degree of openness of each country to non-euro area imports rather than to the heterogeneity in the structure of imports.     

Embedded industrial production systems: Lessons from waste management in zinc production

To meet the sustainability challenge private companies must implement corporate strategies and adopt novel technologies. The technical and social embeddedness of industrial production systems, however, complicates these systems' transition towards sustainability. In the paper, mechanisms and conditions are reported for the development and implementation of waste management options in embedded industrial production systems. The focus is on the Dutch zinc production industry, which had to deal with a major waste problem; the generation of jarosite. The industry's options were to increase the jarosite waste storage capacity, to develop a jarosite treatment process or to switch to a zinc-ore of low-iron content whereby no jarosite waste would be generated anymore. Required conditions appeared to be a combination of technological capability and technical embedding and favourable economics. Case study research, however, revealed that adequate stakeholder management is crucial to address social pressure exerted and to obtain external acceptance for any transition strategy. Whilst appropriate, internal technological capabilities are important, effective interactions with and enrolment of various firm-external actors are crucial. In the case of zinc, access to the heterogeneous external actor network was critical for the development of the jarosite treatment solution direction. In conclusion, both the technical, organizational and social embedding of new technologies are crucial for successful implementation.     

Optimal design of trade institutions

We model an economy with social institutions that facilitate trade and induce three types of costs: establishment costs, access costs, and use costs. Use costs are specific transaction costs related to the use of these trade institutions. We assume that a trade institution is economically completely determined by the costs it imposes and by the effects on the trades it facilitates. We extend the Pareto efficiency concept to include various modes of organization of social institutions: the costs and benefits of these organizations are expressed in the trades they facilitate.Within this setting we discuss a valuation equilibrium concept, in which all agents use a common conjectural price system that assigns to every trade institution the price vector that would prevail under it. This feature of the equilibrium is important in securing the second welfare theorem, and is new to the analysis of economies with costly trade. Since the use costs can be nonlinear, there are non-convexities that prevent the second welfare theorem from obtaining in a finite economy, but we show it for large economies.Received: 3 April 2002, Accepted: 30 April 2003, JEL Classification: D59, D70, H49Robert P.

Preliminary test estimators of the parameters of simple linear model with measurement error

In this paper, we discuss the properties of preliminary test estimators (PTE) of the parameters of simple linear model with measurement error (ME model) when the slope of the linear model is suspected to be zero. Expressions of the bias, MSE and efficiencies are obtained under conditional as well as unconditional situations with known reliability coefficient. Conditional model results are compared to the standard model without measurement error. We also provide the unconditional model analysis in finite samples. Asymptotic theory under local alternatives is developed when the variance of measurement error or the ratio of the variance of the model error relative to the variance of the measurement error is known. Asymptotic expressions of bias and MSE of the estimators along with their efficiencies are obtained. In every case, it is shown that the measurement error tend to increase the variability of the estimators compared to the estimators without measurement error. Graphs and tables are provided to see these results and to determine optimum level of significance for minimum guaranteed efficiency. Received October 2001 RID="*" ID="*"  A. K. Md. E.

Inpatient nursing unit volume, length of stay, cost, and mortality

Nursing unit volume-outcome relationships exist for patients assigned selected DRGs. This finding suggests that, in some cases, aggregating inpatients with similar clinical conditions may result in lower cost of care, shorter length of stay, and fewer hospital deaths.
