This article describes how the management and organization of the South African 2010 FIFA World Cup stadium program shaped the current legacy of an oversupply of overdesigned and underutilized stadiums. The article identifies seven key factors that explain the differences between expected benefits and the actual legacy. Identification of these factors contributes to the increasing academic interest in explaining the poor legacy outcomes of mega‐events. In conclusion, we recommend that future host country governments defragment their stadium programs by establishing a World Cup Delivery Authority (WCDA), with responsibility for the leadership and coordination of the stadium program.  相似文献

In this paper, we analyze the labor market impacts of immigration under flexible and rigid labor market regimes. A general equilibrium framework is developed, accounting for skill heterogeneity and labor market frictions, where unemployed medium‐skilled manufacturing workers are downgraded into low‐skilled service jobs, while low‐skilled service workers might end up unemployed. The analytical analysis shows that medium‐skill immigration decreases low‐skilled unemployment under the flexible regime, indicating a complementarity effect, while the rigid regime induces a substitution effect, leading to low‐skilled unemployment. Moreover, it leads to wage polarization. In a numerical analysis, the economic effects of different migration scenarios are quantified.  相似文献

This study develops a moderation model to examine the role of a proactive environmental strategy on eco‐innovation. Drawing upon the perspectives of contingency theory, this study argues that the impacts of sustainability strategy on eco‐innovation depend on market demand, innovation intensity and government subsidy. The sample used to test the hypotheses is obtained from the Community Innovation Survey in Taiwan. A total of 2955 manufacturing firms are included in the final sample. A logit moderating regression is adopted to analyze the models. The results reveal that market demand and government subsidy positively moderate the relationship between environmental strategy and eco‐innovation. Specifically, firms are more likely to adopt a proactive environmental strategy to improve eco‐innovation under high levels of market demand and government subsidy. Furthermore, the results indicate that innovation intensity affects the effect of environmental strategy on eco‐innovation, but the direction of the influence varies with different categories of eco‐innovation.

This article examines the transferability of the concept of gentrification away from its Anglo‐American heartland to the cities of Asia Pacific and specifically Hong Kong. An epistemological argument challenges such theoretical licence, claiming that conceptual overreach represents another example of Anglo‐American hegemony asserting the primacy of its concepts in other societies and cultures. Past research suggests that if gentrification exists in Asia Pacific cities it bears some definite regional specificities of urban form, state direction and, most surprising from a Western perspective, a potentially progressive dimension for some impacted residents. Closer examination of urban discourse in Hong Kong is conducted through analysis of English and Chinese language newspapers. In both instances, gentrification is barely used to describe the pervasive processes of urban redevelopment, which otherwise receive abundant coverage. Interviews with local housing experts confirm the marginality of gentrification in academic and public discourse, and the power of a local ideology that sees urban (re)development unproblematically as a means of upward social mobility. However, in the decade‐long housing bust after 1997, growing inequality has encouraged a nascent class analysis of the property market, an ontological awakening that may prove more favourable to the identification of gentrification in an Asia Pacific idiom.  相似文献

The increasing use of demand‐side management, as a tool to reliably meet electricity demands at peak time, has stimulated interest among researchers, consumers and producer organiza‐tions, managers, regulators and policymakers. This research reviews the growing literature on models which are used to study demand, customer base‐line (CBL) and demand response in the electricity market. After characterizing the general demand models, the CBL, based on which the demand response models are studied, is reviewed. Given the experience gained from the review and existing conditions, the study combines an appropriate model for each case for a possible application to the electricity market; moreover, it discusses the implications of the results. In the literature, these aspects are studied independently. The main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent. The review is expected to enhance the understanding of the demand, CBL and demand response in the electricity market and their relationships. The objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times. This enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability.  相似文献

In this paper we analyze whether cross‐sector partnerships enable companies to respond to the specific conditions at the base of the pyramid (BOP). We develop three hypotheses in which we argue how cross‐sector partnerships support companies to face unfamiliar conditions in these markets. We test the developed hypotheses against the data of 103 companies operating in BOP‐markets. The results show that companies rely on organizations from the civil society sector in order to meet customer needs. Partners from the business sector are supportive when responding to restrictive market conditions. Institutional partnerships should be considered when companies aim at responding to the regulatory environment. We outline theoretical and managerial implications and reflect some limitations of the study. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment.  相似文献

Drawing on the contextual perspective, this study provides novel empirical evidence on how the organisational context (specifically, the firm's human resource strategy) has an effect on employee proactivity. We use matched data from managers and employees in 102 Spanish professional service firms to examine how high performance work systems contribute to enhance employee proactive behaviours through two motivational variables: role breadth self‐efficacy and flexible role orientation. Results of a multilevel study demonstrate that role breadth self‐efficacy mediates between HPWS and employee proactivity, but flexible role orientation does not mediate this relationship.  相似文献

This tutorial provides an introduction to Palm distributions for spatial point processes. Initially, in the context of finite point processes, we give an explicit definition of Palm distributions in terms of their density functions. Then we review Palm distributions in the general case. Finally, we discuss some examples of Palm distributions for specific models and some applications.  相似文献

This paper investigates volatility spillover in the Nigerian sovereign bond market arising from oil price shocks, using Vector Autoregressive Moving Average ‐ Asymmetric Generalized Autoregressive Conditional Heteroscedasticity (VARMA‐AGARCH) model. The paper covers the period March 22, 2011 to April 14, 2016 and makes use of the daily data of the Nigerian Sovereign Bond, Brent oil and West Texas Intermediate (WTI), respectively. We endogenously and sequentially detect structural break points using the test of Bai and Perron (2003) framework. In order to accurately estimate the model, we modify it by incorporating the break points into the VARMA‐AGARCH model, a process which if ignored would lead to model misspecification. The results obtained demonstrate a significant cross‐market volatility transmission between oil and sovereign bond market with ample sensitivity to structural breaks. The study also computes optimum weight portfolio and hedge ratio both with and without structural breaks and results equally indicate sensitivity to structural breaks.  相似文献
