Freight demand elasticity studies vary significantly in terms of the demand measure, data type, estimation method, commodity type, etc. This wide variation makes it difficult to compare empirical estimates when the differences may arise in part from the methods and data used. In this paper we conduct a comparative analysis to identify systematic sources of influence on direct price elasticity estimates in the context of freight transport, distinguishing between road, rail, and sea transport, using published direct price elasticities from 12 elasticity-derivative studies from five countries. The study focuses on revealed preference elasticities defined by the freight rate for tonnes and tonne kilometres of inter-city freight movements. Systematic sources that explain differences in direct price elasticities include the demand elasticity measure, mode, commodity class, model estimation form, country, and temporal nature of data (e.g., cross-section). Analysts can utilise the model outputs to adjust the empirical evidence from specific studies to control for differences that impact on the behavioural implications of comparative evidence. 相似文献

A bstract . This article examines two mechanisms through which social networks are related to job mobility: (1) access to diverse sources of information about job openings and (2) nonredundant sources of influence. Using data on job changing and social networks among television station managers, we assess the extent to which job information and influence variables mediate the relationship between social network structure and getting a better job. Results indicate that there is an association between job mobility and having nonredundant contacts, but our measures of the information and influence mechanisms are not significant mediators. We conclude by reexamining the network-resource model that forms the basis for much of the research on the relationship between social networks and job mobility. 相似文献

In this paper, we estimate a three-equation recursive model of the rate-of-return phase of the regulatory hearing process. Separate equations are estimated for the firm's requested rate of return, the staff's recommended rate of return, and the commission's approved rate of return. The sample used in this estimation contains 122 observations of actual rate cases that were decided between 1980 and 1984. There are 73 electric companies and 37 states represented in this sample. The model differs from prior work in this area by (1) incorporating a separate equation to explain the commission staff's recommended rate of return, and (2) including the regulated companies' actual expenditures on the hearing process as a variable in all three equations. 相似文献

Punishment,counterpunishment and sanction enforcement in a social dilemma experiment 总被引:1,自引:0,他引:1
We present the results of an experiment that explores the sanctioning behavior of individuals who experience a social dilemma.
In the game we study, players choose contribution levels to a public good and subsequently have multiple opportunities to
reduce the earnings of the other members of the group. The treatments vary in terms of individuals’ opportunities to (a) avenge
sanctions that have been directed toward themselves, and (b) punish others’ sanctioning behavior with respect to third parties.
We find that individuals do avenge sanctions they have received, and this serves to decrease contribution levels. They also
punish those who fail to sanction third parties, but the resulting increase in contributions is smaller than the decrease
the avenging of sanctions induces. When there are five rounds of unrestricted sanctioning, contributions and welfare are significantly
lower than when only one round of sanctioning opportunities exists, and welfare is lower than at a benchmark of zero cooperation.

Industrial manufacturers are innovating their business models by shifting from selling products to selling outcome-based services, where the provider (manufacturer) guarantees to deliver the performance outcomes of the products and services. This form of business model innovation requires a profound yet little understood shift in how value is created, delivered, and captured. To address this research gap, our study examines two successful and four unsuccessful cases of this shift. We find that effectiveness in business model innovation hinges on the three process phases that unfold in collaboration with the customers: value proposition definition, value provision design, and value-in-use delivery. We also find that that success is determined by the alignment of specific value creation and value capture activities in each phase: identifying value creation opportunities—agreeing on value distribution in value proposition definition, designing the value offering—deciding on the profit formula in the value provision design, and finally refining value creation processes—regulating incentive structures in the value-in-use delivery. Our process model contributes to the literature and practice on business model innovation by providing a thorough understanding of how alignment of value creation and value capture processes is ensured, whilst paying special attention to their interdependence and the interactions between provider and customer. 相似文献

This article applies a labor process analysis to the issue of employment rights in the particular context of gender inequality
and unlawful discrimination in the recruitment process. It criticizes conventional perspectives on employee rights for their
failure to examine critically managerial power and prerogative and its implications for gender inequality. The article outlines
two particular labor process theories of gender divisions and inequality. In exploring the strengths and weaknesses of these
more critical perspectives, the article highlights the analytical significance that they ascribe to power asymmetries in the
labor process and labor market. Building on this perspective, the analysis then presents empirical data on gender discrimination
in the selection practices of contemporary UK organizations. The research material reveals how gender discrimination can be
reproduced, rationalized, and resisted. These empirical findings are theorized through a combined labor process analysis of
power, knowledge, and identity in recruitment practices. We conclude that labor process analysis facilitates our understanding
of the deep-seated barriers that continue to impede the protection of employee rights in workplace practices. 相似文献

Cooperation or resistance? Representing workers' health and safety in a hazardous industry 下载免费PDF全文

This study considers the actions of worker health and safety representatives in coalmines in Queensland, where there is little evidence of the facilitating role of management previous studies have associated with the successful operation of worker representation in occupational health and safety. It examines how worker representatives deliver their pluralist representational role in a context characterised by essentially unitary thinking amongst their employers and the effectiveness of the strategies they use. 相似文献
