Since the early 1990s, the US natural gas sector is characterized by substantial industry restructuring as a result of regulatory requirements following a liberalization objective. Accordingly, firms have chosen different strategies as a reaction of regulatory constraints, such as acquisitions, forming holding companies, or joint venture investment. In order to contribute to the success of business strategies driven by the regulatory framework, the purpose of this paper is to provide first evidence for the impacts of business strategies on a firm's efficiency within the gas transmission business.

The approach taken is a stochastic frontier analysis.

The results highlighted significant effects of acquisitions, holding structures, and joint ventures within the industry on the firms' technical efficiency estimates. The paper finds evidence for efficiency improvements caused by the new shareholder. The results suggested those holdings to be successful which have great experience in the construction and operation of oil pipelines. In the case that firms formed a joint venture to construct and operate a gas transportation pipeline, the empirical analysis showed a negative impact of such a joint venture on technical efficiency of the pipeline company.

The paper provides evidence for the missing link between operating performance and the evaluation of different business strategies in terms of efficiency within the natural gas interstate pipeline industry.

Waiting for a bus may represent a period of intense exposure to traffic particles in hot and noisy conditions in the street. To lessen the particle load and tackle heat in bus stops a shelter was equipped with an electrostatic precipitator and a three-step adiabatic cooling system capable of dynamically adjust its operation according to actual conditions. This study evaluates the effectiveness of the Airbitat Oasis Smart Bus Stop, as the shelter was called, to provide clean and cool air.

The particle exposure experienced in this innovative shelter was contrasted with that in a conventional shelter located right next to it. Mass concentrations of fine particles and black carbon, and particle number concentration (as a proxy of ultrafine particles) were simultaneously measured in both shelters. Air temperature, relative humidity and noise level were also measured.

The new shelter did not perform as expected. It only slightly reduced the abundance of fine particles (−6.5%), but not of ultrafine particles and black carbon. Similarly, it reduced air temperature (−1 °C), but increased relative humidity (3%). Its operation did not generate additional noise.

The shelter's poor performance was presumably due to design flaws induced by a lack of knowledge on traffic particles and fluid dynamics in urban environments. This is an example where harnessing technology without understanding the problem to solve does not work.

It is uncommon to come across case studies like this one in which the performance and effectiveness of urban infrastructure can be assessed under real-life service settings.

The purpose of this paper is to explore drivers of alliance formation in a specialized supply chain from a manager’s perspective, focussing on firm-specific resources, resources embedded in inter-firm relationships and capabilities under the control of the focal firm.

This paper focusses on the resource-based view to obtain insights from the analysis of a manager survey conducted in Canada’s beef sector, applying a logistic regression approach to study alliance formation.

In identifying significant roles for resource richness and diversification of resource usage, the analysis highlights the importance of resource characteristics underlying factor market imperfections as drivers of alliance formation in a single primary input supply chain. The results suggest that resource heterogeneity is important for alliance formation and organizational success in specialized supply chains.

If previous alliance-related experience of managers, controlled for in the underlying cross-sectional survey, serves as an approximation for persistent unobservables impacting the alliance formation decision, we may face spurious state-dependence.

Managers interested in building compatible alliances in specialized single primary input supply chains may benefit from an improved understanding of the differential role of resource characteristics and resource heterogeneity for alliance formation, as these can function as a source of competitive advantage.

The analysis provides new insights from an individual manager’s perspective on alliance formation drivers in a specialized agri-food supply chain, thereby solidifying extant findings on alliance formation obtained in other sectors. The study contributes to the understanding of the role of resources in alliance formation with regard to prior relationship experience, resource heterogeneity and thus causal ambiguity, thereby also contributing to the debate of the role of relational capabilities vs firm-internal resources for sustained competitive advantage.
