Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification.  相似文献

This paper reviews the results of a structural decomposition analysis in which the annual changes in a number of air pollutants and solid waste are decomposed according to their causes. The analysis in this paper is applied with the help of the so-called National Accounting Matrix including Environmental Accounts (NAMEA) for the Netherlands, covering annual data for the period 1987-1998. In a sensitivity analysis it is shown that the average of any pair of so-called 'mirror image' decomposition forms will substantially reduce the variation in the estimates. These mirror image couples are approximately just as reliable as the full average of all decomposition forms. Besides reliable results, the full average also foresees the mutual comparability between the distinguished change factors and is therefore applied in the empirical analyses presented in this paper. The results of these analyses contain the macro-economic developments, results on the industry level as well as a comprehensive overview of the origin and destination of pollution in the Dutch economy that includes the environmental consequences of consumption and international trade.  相似文献

This research presents the results of a multiple method study exploring the future competence requirements for purchasing and supply management (PSM) professionals in the face of increasing demand for innovative and sustainable product and service solutions. Data collection consisted of four stages: first, a World Café was held to gather experts’ insights into PSM skills, which helped to refine a first survey round of eleven open-ended questions. A second survey round then followed, presenting four scenarios based on the results of the initial round. Finally, interviews were conducted to explore the results in detail. The participants in all stages were senior PSM experts from a variety of sectors, including manufacturing and service organisations, as well as academic institutions, consulting firms and non-governmental organisations. The results show that the expected changes in the future business environment mainly concern the application of digital technologies, increasing supply chain flexibility and transparency, sustainability performance and the need to build soft skills to support interpersonal relationships as well as hard skills to support supply chain design.  相似文献

This study investigates the performance of socially controversial companies during a financial crisis. Companies are usually considered controversial if they are involved in controversial businesses such as alcohol, tobacco, firearms, nuclear etc. The results show that controversial firms exhibit higher firm value as well as better accounting performance during the Great Recession than otherwise similar, albeit non-controversial, firms. The results are consistent with the notion that the demand for controversial products remains relatively stable even during a stressful time. Further analysis confirms the results, including random-effects analysis, GMM dynamic panel data analysis, and instrumental-variable (IV) analysis. The results of this paper are particularly relevant to portfolio management, where controversial firms may be added to portfolios to inoculate them from a negative shock brought about by an economic crisis.  相似文献

The purpose of this paper is to present the methodology and results of an experiment performed with a group of public agency executives in order to capture an agency-wide priorityutility function. A method based on the Churchman-Ackoff-Arnoff successive comparisons approach was developed for easy administration to the policy makers. The results produced high levels of concordance among the individual executives; the use of the results as input for other decision-making, such as resource allocation or the relative effectiveness of programs, is discussed.  相似文献

ABSTRACT

The paper investigates the value relevance of accounting information in the Czech Republic in 1994–2001. Value relevance is understood as the ability of financial statement information to capture or summarise information that affects share values and empirically tested as a statistical association between market values and accounting values. The objective of the study is to investigate the validity of the value relevance methodology by finding an accounting setting where the results of value relevance tests might be predicted unambiguously. If the results of these tests confirm the predicted results, the validity of the value relevance methodology might be assumed. A transition economy represented by the Czech Republic provides such an institutional and accounting setting. It might be assumed that value relevance of accounting information is lower in a transitional economy than in a well-developed market economy. It can also be assumed that the value relevance increases over time as a result of the progress in transition. The results of the study confirm these predicted results and give thus supportive evidence of the validity of the value relevance methodology.  相似文献

Two experiments were carried out to test the theory of reasoned action of Fishbein and Ajzen. The measurements were done using two category scales and two psychophysical scales. No consistent difference in results was found between the four modalities. However, if the latter were used as multiple indicators for the model components in a latent variables model, the parameter values did increase as compared to those in single indicator models. A multitrait-multimethod model allowed for correction of method effects. Though the results of the multiple indicator models did not differ significantly from the results of the single indicator models, the increase in explained variance of intention by 17% in the first experiment and 15% in the second experiment can not be ignored in applied research. Psychophysical scales are attractive because they are well suited for use as multiple indicators.  相似文献

The main aim of this contribution is to present and discuss critically some of the results from the longitudinal analysis carried out in eight cities in five European countries within the general framework of the ESOPO project. In particular I will use these results in order to understand what longitudinal analysis can tell us as soon as we compare different citizenship systems using process-produced data from social assistance schemes as a relevant indicator. The contribution is divided into three sections. The first section will address some methodological issues and illustrate the driving hypothesis. The second section will present some main results from the longitudinal analysis carried out in the ESOPO project. The third section will highlight the institutional dimension and its role in shaping clients' recipiency dynamics, paying particular attention to the development of an interpretative framework.  相似文献

This paper reviews, and synthesises within a uniform framework, a number of analytical results on the built‐in flexibility of taxation. Established results for income taxes are reviewed and integrated with recent results for consumption taxes. These help to provide a better understanding of the determinants of the revenue responsiveness properties of different taxes. They also provide convenient expressions for the calculation of tax revenue elasticities in practice. It is shown that the magnitude of revenue elasticities can be expected to differ substantially for alternative taxes, for different forms of the same tax, and for the same tax over time as incomes change relative to tax thresholds and as consumption patterns change. These results are especially relevant for the many industrialised countries which have undertaken major fiscal reforms in recent years with, often unintended, consequences for revenue elasticities.  相似文献

Brodie and de Kluyver have reported empirical results in which simple naive models have produced forecasts as accurate as those derived from econometric models. I apply some recent theoretical results to show that these findings are plausible. I also suggest some general conditions under which econometric models will outperform naive models.  相似文献

The idea of an urban renaissance — based on a celebration of city life and its possibilities — is timely given half of the world's population now resides in urban areas. Yet, as appealing as this prospect may be, both in principle and planning theory, it remains at odds with the desires of many residents who seek ‘lifestyle living’ in low‐density suburban or ex‐urban settings. This article presents the results of a qualitative investigation of what it means to ‘live on the edge’ in a peri‐urban village, as understood by residents living in those settings. These results are evaluated in light of phenomenological literature on authentic and inauthentic places, and the myriad reasons so‐called amenity migrants choose the peri‐urban village as their preferred residential location. The results of in‐depth interviews with 28 residents are presented as a four‐part typology of ‘active’ lifestylers and those searching for community, and ‘passive’ speculators and those seeking a civilized society. Though prior work suggests people are attracted to the peri‐urban village for its bio‐physical environmental features, this research suggests socioeconomic factors and opportunities for active place‐making experiences are as, if not more, important.  相似文献

The method of generalized confidence intervals is proposed as an alternative method for constructing confidence intervals for process capability indices under the one-way random model for balanced as well as unbalanced data. The generalized lower confidence limits and the coverage probabilities for three commonly used capability indices were studied via simulation, separately for balanced and unbalanced cases. Simulation results showed that the generalized confidence interval procedure is quite satisfactory both in the balanced and unbalanced cases. Examples are provided to illustrate the results.  相似文献

When employees work in teams, the whole organization benefits with better results and increased profits. But what benefits do employees get as a result of teamwork? How can their attention be properly focused on the kinds of results the organization needs? And, how should they be rewarded for producing the desired results? Let's explore the options.  相似文献

Nurse turnover has been a serious challenge to the efficiency and effectiveness of any health-care delivery system. Various antecedents of turnover are examined in this study in attempt to identify the most critical causes of the problem. One hundred and eighty nurses from a large hospital in Singapore participated in the survey. The results show that a) stress strikes throughout different stages in turnover development; b) professional commitment is a significant cause of turnover cognition, but not turnover intention; and c) organizational commitment and supervision satisfaction are among the top predictors of turnover intention. These results deviated from the apprehension of many health administrators about the causes of the nursing turnover, thus provided clues as to how to mitigate the problem. And, as they were compatible with the results of studies on Canadian and American nurses, these results contributed to the empirical generalization process. The implication of the findings is discussed in the paper.  相似文献

This paper provides a set of results on the econometric identifiability of binary choice models with social interactions. Our analysis moves beyond parametric identification results that have been obtained in the literature to consider the identifiability of model parameters when the distribution of random payoff terms is unknown. Further, we consider how identification is affected by the presence of unobservable payoff terms of various types as well as identification in the presence of certain forms of endogenous group membership. Our results suggest that at least partial identification may be achieved under assumptions that in certain contexts may be plausible.  相似文献

Using banking sector and stock market development indicators, we examine the effect of institutional quality on financial development in developed and developing countries. Empirical results are based on dynamic system generalized method of moments estimations and demonstrate that a high-quality institutional environment is important in explaining financial development, specifically for the banking sector. However, the stock market development-institution relationship is contingent one, characterized by a non-monotonic pattern. The results are robust to two measurements of institutions and governance indicators, as well as estimation methods.  相似文献

Supply chains need specific investments for improved performance in terms of lead‐time, cost, and quality. We study the contractual choice of a coordinator to either centralize or delegate the investment decision in a three‐stage chain. The analysis derives closed‐form results for the economic performance of three decentralized contracting schemes under asymmetric information on investment cost, as well as the optimal full revelation results. The results show that the observed practice of tier‐1 delegated investments leads to relatively poor performance because of underinvestment. We illustrate the findings with the Boeing 787 debacle.
