This paper analyses aggregate labour dynamics during the global financial crisis in Japan and the role of non-standard work using micro data. The analysis proceeds in two steps. First, using comprehensive establishment-level datasets for the period 1991–2009, it provides a detailed portrait of the adjustment behaviour of establishments at the micro level. Second, it compares aggregate labour market dynamics during the global financial crisis with that observed during the 1997 crisis and decomposes the observed differences into components that can be attributed to changes in the micro-adjustment behaviour of Japanese establishments, changes in the incidence of non-standard work and changes in the distribution of shocks across establishments. It finds that the incidence of non-standard work has increased considerably, worker turnover is much higher among non-standard than standard workers and adjustments in working-time are less important for non-standard workers. Counterfactual simulations suggest that the employment response during the global crisis would have been smaller if the incidence of non-standard work remained at the level observed during the 1997 crisis. The relatively small employment response observed during the global financial crisis is therefore driven by factors other than the increase in the incidence of non-standard work.  相似文献

土地出让与城镇化质量作为城镇化的主要依托和核心追求,二者的关系影响到城市的可持续发展。以长江经济带为例,构建土地出让与城镇化质量综合评价指标体系,利用熵值法和耦合协调模型对二者耦合协调的时空差异做出实证研究,并利用ArcGIS将其空间显化。结果表明:研究期内长江经济带土地出让与城镇化质量的协调度呈现先增后减再增趋势;二者的协调度自西向东逐步增加,耦合度无明显分布规律,总体呈高水平耦合状态;土地出让与城镇化质量的协调度在城市群间的差异显著,但城市群内部的差异逐步减小。从土地出让与城镇化质量的耦合协调发展的视角,为实现城市健康可持续的发展提出政策建议。  相似文献

The purpose of this study is to examine the airport service quality dimensions based on the ASQ survey and investigate the best predictor for overall satisfaction. The context of this study is the klia2 terminal passengers, which are predominantly users of the low-cost carriers at Kuala Lumpur International Airport. Secondary data obtained from the airport operator on the 2016 ASQ survey for the klia2 terminal was analysed using the PLS-SEM method. The grouping and impact of the thirty-three service quality elements from the ASQ survey were tested against the overall satisfaction element. The findings indicated that twenty-two out of the thirty-three elements were valid measures for the klia2 terminal users which forms the eight dimensions i.e. access, airport environment, airport facilities, arrival services, check-in, finding your way, passport and security. Airport environment was found as the best predictor in determining passengers’ overall satisfaction at klia2 terminal and should be given particular focus by the airport operator for continuous improvements.  相似文献

The surge in air transport demand and the increasingly competitive and volatile market dynamics due to airline deregulation are rapidly transforming airports’ character into multi-service firms and destinations. As a result, service performance measurement of significant systems and their consequent impact on airport users are crucial in creating better airport service design, operation and management for sustainable competitive advantage. The present study 1) assesses the applicability of the Airport Indicators of Passenger Experience (AIPEX) model on Shanghai Pudong International Airport (PVG), and 2) tests a theoretical model that explores the direct and indirect relationships among airport service quality, passenger affective image and satisfaction, as well as the moderating mechanism of passenger type (travel purpose) in these associations. The results indicate that, the AIPEX model fits the PVG context for airport service performance assessment. Also, the theoretical model suggests robust direct associations among processing/non-processing domains and passenger satisfaction, as well as the processing domain and passenger affective image, except non-processing domain and passenger affective image relation. Moreover, significant mediating and moderating effects of passenger affective image and travel purpose on the significant positive direct associations are found. Further, implications for theory and practice are discussed.  相似文献

This paper empirically examines the effects of export product diversification on overall export quality in a panel data set of 115 countries from 1970 to 2010. It uses the data sets of the overall export quality and three export diversification measures of the International Monetary Fund: the extensive margin (variation in the number of new products exported), the intensive margin (variation in export values among existing exports), and the overall (Theil) index. It finds that export quality has only been increasing with a higher variation in export values among existing exports in low- and lower-middle-income countries. It also observes that export quality has been increasing with both a higher variation in export values among existing exports and new products exported in upper-middle- and high-income countries. The results are robust to the changing measures of controls in the benchmark model, the inclusion of many other controls; i.e. various measures of globalization, country size, factor endowments, macroeconomic stance, etc., and the exclusion of outliers.  相似文献

以城市自来水水质事故致因为研究视角,首先识别供水水质风险因素,并从单、双及多因素角度分析供水水质风险因素间的耦合关系,再借助N-K模型对2008—2017年全国所发生的362起城市重大供水水质风险耦合度进行度量。结果表明:城市自来水供应动态系统中,水质风险率随着参与耦合的风险因素的增多而增加;管理因素风险是水质风险的内因,风险管控是规避水质风险的关键;环境因素风险对水质事故的发生起推动作用。  相似文献

Unlike previous studies in which a single index was used to measure audit quality, this study establishes a new comprehensive index to measure audit quality via Discretionary Accrual, as estimated by Jones’ basic model (1991) and Audit Opinions. The former is used to measure the quality of financial statements, and the latter is used to measure the auditors’ independence in the mainstream international literature. We examine whether and how an auditor’s gender affects the quality of his or her audits under the framework of empathy theory and gender role socialization theory. Using a large sample of 9861 auditor-firm-year observations from Chinese A-share–listed companies from 2011 to 2015, we find that the audit quality of signed auditors shows significant gender differences: these significant gender differences differ from the findings of previous studies that female auditors could provide a higher-quality audit than male auditors; that is, in our study the audit quality of the male auditors exceeds that of the female auditors. After distinguishing the positive and negative directions of the Discretionary Accrual, we find no significant gender differences in audit quality between male and female auditors when the earnings had been adjusted upward by the client; that is, female and male auditors had the same audit risk perception. However, when the client adjusted earnings downward, which indicates a lower audit risk for the auditor, the audit quality of female auditors was significantly lower than that of the male auditors. After controlling for the age and position of the auditors, we also find that the gender differences in the auditors’ audit quality decreased significantly or even disappeared when the auditor’s age exceeded 45?years and/or their position was manager or above. These results are consistent with the empathy theory and gender role socialization theory.  相似文献
