This article uses both cross‐sectional and longitudinal methods to evaluate the national industrial relations systems of 30 Organisation for Economic Co‐operation and Development (OECD) countries from 1993 to 2005. We adopt a pluralistic view of industrial relations that gives equal weight to efficiency and equity, along with a general systems model consisting of input, process and output. We rank each country in terms of a combined score of efficiency and equity. We find that the 30 OECD countries can be separated into three distinct groups (high on both equity and efficiency; high on efficiency but low on equity; moderate on equity and low on efficiency), and that these groups exhibit considerable stability over time.  相似文献

在大力探索生态产品价值实现背景下,生态旅游作为公共产品,为推动生态产品价值实现和中国特色生态文明建设新模式的形成提供有力支撑。本研究选取南山国家公园线路为案例,以S-O-R理论为基础,构建生态旅游产品购买意愿模型,探究生态旅游产品在微信朋友圈购买意愿的内在机制。研究发现:(1)生态旅游产品在微信朋友圈的购买意愿存在“营销媒体特征—感知功利价值—购买意愿”和“社交媒体特征—感知享乐价值—购买意愿”两种形成机制;(2)生态旅游产品在微信朋友圈的购买意愿同时受到功利性因素和享乐性因素的影响,但功利性因素的影响占主导作用;(3)生态旅游产品的价格和产品图片的美观性对感知功利价值的影响较强;(4)微信朋友圈的社交存在感和微信好友的能力对感知享乐价值的影响较强;(5)不同人口学特征下,被调查者的购买意愿有显著差异。建议开展组合式营销、改善营销信息的内容和质量、保持高度的用户粘性、重视“专业形象”打造、针对主要客源市场“有的放矢”营销等实践,以促进南山国家公园生态旅游产品的价值实现。  相似文献

Health insurance reform in Massachusetts lowered the cost of both pregnancy (by increased coverage of pregnancy‐related medical events) and pregnancy prevention (by increasing access to reliable contraception). We empirically examine fertility responses and find no overall effect from increased coverage due to the Massachusetts reform. This finding, however, masks substantial heterogeneity. For married women aged 20 to 34—with high latent fertility and pregnancy wantedness—fertility increased by approximately 1%. For unmarried women in the same age range—for whom pregnancies are typically unwanted—fertility declined by 8%. (JEL I13, I18, J13)  相似文献

While monetary easing and increasing participation of financial institutions in commodity trading have enhanced the financialization of commodity markets, this paper investigates empirically whether the impact of global liquidity on commodity prices has grown since the crisis. For each commodity group, this paper uses a structural vector autoregression (SVAR) model to address the short‐run relationship between global liquidity and commodity prices. The key finding is that the effect of global liquidity on commodity prices becomes more salient since the global financial crisis. This paper also suggests a price‐based liquidity indicator has a greater explanatory power for the commodity price dynamics than monetary aggregates.  相似文献

This paper argues that trade union activism within the new era of information and communication technologies (ICTs) offers the potential for unions to become more inclusive of under‐represented groups. Traditional conceptions of activism, participation and democracy within trade unions require physical presence at meetings at times and in spaces incompatible with caring responsibilities and atypical hours of work. This restricts the participation of women and other ‘atypical’ workers in trade unions. The paper explores the complexities of electronic forms of union activism in practice, indicating that while some positive features are experienced, there are also a range of obstacles, barriers and possible negative consequences.  相似文献

This paper investigates relationship conflict amongst Taiwanese adolescents. The data was taken on Taiwanese adolescents aged 15–17 who attended 16 high schools which are located in north, middle, south, and the east of Taiwan. They were invited to participate in the study during the 2010 school year. This paper explores the patterns among relationship conflict including its impact, the social dimensions, the time aspects, the psychological implications, the physical dimensions, and the performance and overall risks involved in group atmospheres. The ways relationship conflict handling styles correlate with the group atmosphere were also explored. Each one of the risk variables’ correlations and relationship conflict were explored. As part of this study upon correlating each one of the risk variables and relationship conflict, the researchers studied the correlations between the risk variables and the group atmosphere.  相似文献

This article assesses the impact of armed conflict on the drinking water service of Basrah from 1978 to 2013 through an ‘urban warfare ecology’ lens in order to draw out the implications for relief programming and relevance to urban studies. It interprets an extensive range of unpublished literature through a frame that incorporates the accumulation of direct and indirect impacts upon the hardware, consumables and people upon which urban services rely. The analysis attributes a step‐wise decline in service quality to the lack of water treatment chemicals, lack of spare parts, and, primarily, an extended ‘brain‐drain’ of qualified water service staff. The service is found to have been vulnerable to dependence upon foreign parts and people, ‘vicious cycles’ of impact, and the politics of aid and of reconstruction. It follows that practitioners and donors eschew ideas of relief–rehabilitation–development (RRD) for an appreciation of the needs particular to complex urban warfare biospheres, where armed conflict and sanctions permeate all aspects of service provision through altered biological and social processes. The urban warfare ecology lens is found to be a useful complement to ‘infrastructural warfare’ research, suggesting the study of protracted armed conflict upon all aspects of urban life be both deepened technically and broadened to other cases.  相似文献

This paper investigates the impact of governance mechanisms on small and medium‐sized enterprise (SME) cash holdings from 2000 to 2009, employing static and dynamic panel data analyses. We find no evidence that firm governance index and insider ownership affect cash holdings. This might indicate that governance mechanisms in SMEs are relatively weak. We also report that chief executive officer compensation has a positive effect on cash holdings. Firm‐specific factors such as firm size, leverage, and liquidity negatively affect cash holdings, whereas the research and development ratio and operating risk are positively associated with them. Finally, SMEs have target cash holdings and adjust to these.  相似文献

This study examines the relationship between expected stock returns and volatility in the 12 largest international stock markets during January 1980 to December 2001. Consistent with most previous studies, we find a positive but insignificant relationship during the sample period for the majority of the markets based on parametric EGARCH-M models. However, using a flexible semiparametric specification of conditional variance, we find evidence of a significant negative relationship between expected returns and volatility in 6 out of the 12 markets. The results lend some support to the recent claim [Bekaert, G., Wu, G., 2000. Asymmetric volatility and risk in equity markets. Review of Financial Studies 13, 1–42; Whitelaw, R., 2000. Stock market risk and return: an empirical equilibrium approach. Review of Financial Studies 13, 521–547] that stock market returns are negatively correlated with stock market volatility.  相似文献
