P. Elhorst M. Abreu P. Amaral A. Bhattacharjee L. Corrado B. Fingleton 《Spatial Economic Analysis》2016,11(3):249-252
This editorial summarizes and comments on the papers published in issue 11(3) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper proposes spatial and a-spatial indicators to describe the networks of airline companies around the world. The second paper sets forth a two-regime gravity-type model with an endogenous threshold parameter to assess the effect of labour market conditions on interregional migration flows. The third paper utilizes micro-data to explain student migration flows to higher education institutions. The fourth paper is among the first to make use of simulation-based location quotients in a multiregional input–output model. Finally, the last paper provides a purely economic–theoretical model on cooperative limit pricing in the context of spatial competition. 相似文献

This editorial summarizes and comments on the papers published in issue 11(4) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper deals with common factors and spatial dependence in the error term specification of a production function model. The second paper sets forth a New Economic Geography (NEG) model with production activities that vary in their complexity, so as to analyse the impact on specialization patterns across different regions. The third paper measures the efficiency of local public investments using a relatively unknown econometric technique in which the time span over which the variables in the regression equation are measured is increased by one time period every run. The fourth paper adopts a conditional quantile regression approach to determine the impact of people employed in informal jobs on the wage distribution in Colombia and five of its regions. Finally, the last paper proposes and tests two new Bayesian variable selection approaches for spatial econometric models. 相似文献

Information systems are a kind of service systems and they are throughout every element of a modern industrial and business system, much like blood in our body. Types of information systems are heterogeneous because of extreme uncertainty in changes in modern industrial and business systems. To effectively manage information systems, modelling of the work domain (or domain) of information systems is necessary. In this paper, a domain modelling framework for the service system is proposed and its application to the enterprise information system is outlined. The framework is defined based on application of a general domain modelling tool called function-context-behaviour-principle-state-structure (FCBPSS). The FCBPSS is based on a set of core concepts, namely: function, context, behaviour, principle, state and structure and system decomposition. Different from many other applications of FCBPSS in systems engineering, the FCBPSS is applied to both infrastructure and substance systems, which is novel and effective to modelling of service systems including enterprise information systems. It is to be noted that domain modelling of systems (e.g. enterprise information systems) is a key to integration of heterogeneous systems and to coping with unanticipated situations facing to systems. 相似文献

In this article we strive to reconcile equivocal findings about the effects of top leader succession and prior leadership experience on postsuccession organizational performance. In doing so, we draw on insights from theories of human capital, learning, and asymmetric information to better understand the conditions under which leaders increase or decrease postsuccession performance. Employing a sample of 119 newly appointed leaders in the English Premier League (1996–2010), we find the following results. First, relating to the succession event, outside leaders that directly move between leadership positions are associated with higher postsuccession performance while the departure of a prior leader to a leadership position in another organization has a negative effect on postsuccession performance. Second, relating to prior leadership experience, leaders with domestic top leader experience are associated with lower postsuccession performance, while leaders with foreign top leader experience are associated with higher postsuccession performance. © 2015 Wiley Periodicals, Inc. 相似文献

Zimmer (‘The role of copulas in the housing crisis’, Review of Economics and Statistics 2012; 94 : 607–620) provides an interesting case study of the pitfalls of using parametric copulas to understand the US housing crisis in the latter part of 2000s. The original study by Zimmer (2012) employs a finite‐mixture copula to illustrate that the symmetry of the Gaussian copula may not be tenable, especially for US housing price data during the time period from 1975:Q2 to 2009:Q1. We undertake a replication of his study in a wide sense. First, we replicate the study by incorporating revised data and then extending the dataset to include the most recent data. Second, we implement a nonparametric copula estimator recently proposed by Racine (‘Mixed data kernel copulas’, Empirical Economics forthcoming) to the parametrically filtered data used in Zimmer (2012). Our replication finds that the application of the nonparametric copula to the same and extended filtered data provides an alternative flexible specification for copulas. However, the overall cautionary message of the flexible‐form copula espoused in Zimmer (2012) remains. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

We consider efficient estimation in moment conditions models with non‐monotonically missing‐at‐random (MAR) variables. A version of MAR point‐identifies the parameters of interest and gives a closed‐form efficient influence function that can be used directly to obtain efficient semi‐parametric generalized method of moments (GMM) estimators under standard regularity conditions. A small‐scale Monte Carlo experiment with MAR instrumental variables demonstrates that the asymptotic superiority of these estimators over the standard methods carries over to finite samples. An illustrative empirical study of the relationship between a child's years of schooling and number of siblings indicates that these GMM estimators can generate results with substantive differences from standard methods.

Empirical Tests of the Pollution Haven Hypothesis When Environmental Regulation is Endogenous 总被引:1,自引:0,他引:1 下载免费PDF全文
The pollution haven hypothesis (PHH) posits that production within polluting industries will shift to locations with lax environmental regulation. While straightforward, the existing empirical literature is inconclusive owing to two shortcomings. First, unobserved heterogeneity and measurement error are typically ignored due to the lack of a credible, traditional instrumental variable for regulation. Second, geographic spillovers have not been adequately incorporated into tests of the PHH. We overcome these issues utilizing two novel identification strategies within a model incorporating spillovers. Using US state‐level data, own environmental regulation negatively impacts inbound foreign direct investment. Moreover, endogeneity is both statistically and economically relevant.

Resource based relative value scale: a new challenge and opportunity for health care cost management
Beginning in 1992, the use of resource based relative value scale (RBRVS) will greatly change the way physicians are reimbursed for services to Medicare patients. This new system will also have implications for trust funds and corporate providers of health care benefits. 相似文献

This paper uses a newly developed economic return model to estimate the real (inflation adjusted) costs of supply, and rates of return, for the electricity systems in three States over very long time periods. It is shown that because of a combination of public ownership and the use of historical cost accounts, the real return on capital tends to fall with the onset of rapid inflation such as occurred in the mid 1970s In NSW in particular the rapid growth in demand for electricity in the 1970s due to falling real electricity prices and considerable increases in other energy prices has given rise to a major investment program and rapidly developing excess capacity. Higher real electricity prices in the 1980s, combined with the economic slump of 1982, resulted in low or negative growth rates in demand Much of the boom I bust mentality evident in all three States may have been avoided or ameliorated had the electrical supply authorities been required to earn even a very modest real rate of return of (say) 4 or more per cent p.a. which is considerably below the (pre-tax) return earned in the corporate sector. 相似文献
