Leader‐Member Exchange Relationships and Follower Outcomes: The Mediating Role of Perceiving Goals as Invariable

In the present study, we investigated whether perceiving goals as invariable mediated the link between leader‐member exchange (LMX) relationships and role overload, turnover intention, and work performance. Perceiving goals as invariable refers to the extent to which followers believe that the goals in a performance management system represent the absolute standards that they must meet without exception, even if they think other factors are more important (e.g., situational factors or factors that are not associated with goals). In Study 1, perceiving goals as invariable mediated the relationships between LMX and role overload and turnover intention, such that a high‐quality LMX relationship was negatively associated with perceiving goals as invariable, which in turn was positively related to both role overload and turnover intention. In Study 2, social LMX was negatively associated and economic LMX was positively associated with perceiving goals as invariable, which in turn was negatively related to work performance. Furthermore, perceiving goals as invariable mediated the relationship between social LMX relationships and work performance. Theoretical and practical implications and directions for future research are discussed. © 2017 Wiley Periodicals, Inc.     

Tourists’ hotel event experience and satisfaction: an integrative approach

ABSTRACT

Tourists’ hotel event experiences have received little attention in tourism research. By proposing an integrated model of expectation–confirmation theory (ECT) and the experience economy concept, this research explores the relationship between tourists’ event experience and their satisfaction regarding the hotel event setting. The hypothesized model was empirically validated using a sample of 663 tourists who experienced a holiday event at a resort hotel. Results confirmed that the integration of the experience economy and ECT provided a better understanding of tourists’ post-satisfaction in a pleasure-driven setting. This affective–cognitive approach advances the knowledge of tourists’ experiences and satisfaction at hotel events.

生物质能源可利用潜力评价*——以黑龙江省重点国有林区为例

[目的]生物质能源具有污染少、可再生等特点,合理地对其开发利用是黑龙江省重点国有林区经济转型发展的一种探索。通过对黑龙江省重点国有林区生物质能源资源量的计算,明确了生物质能源的可利用潜力及变化趋势,以期为其产业发展的政策制定提供理论参考。[方法]文章利用自下而上估算法,以林木生物质的资源量和农作物秸秆的产量为原始数据,对2005—2015年黑龙江省重点国有林区生物质能源可利用潜力进行评价。[结果](1)研究期间,黑龙江省重点国有林区林木生物质资源可利用潜力小幅下降,农作物秸秆资源可利用潜力稳步上升。(2)林木生物质资源中,商品林采伐剩余物可利用潜力骤降,森林抚育剩余物可利用潜力增加;农作物秸秆资源中,粮食作物秸秆可利用潜力逐年上升。(3)黑龙江省重点国有林区生物质能源可利用潜力随着国家"天保工程"和"重点国有林区全面禁止天然林商业性采伐"政策的实施而发生变化。[结论]黑龙江省重点国有林区生物质能源丰富,可利用潜力较大,其中农作物秸秆资源可利用潜力增速较快。     

四川省重点生态功能区有机农业生产效率研究——基于三阶段DEA模型的实证分析

[目的]有机农业为我国农业绿色发展起到良好的带动作用,但我国有机农业发展中,西部贫困地区较为滞后。针对西部贫困地区有机农业生产效率进行定量分析,揭示影响有机农业生产效率的主要因素,旨在提高该地区有机农业生产效率,丰富区域视角下的有机农业生产研究。[方法]采用三阶段DEA模型对2014年四川省重点生态功能区有机农业生产效率进行量化分析,识别环境变量对有机农业生产效率的影响。[结果]环境因素和随机误差对四川省重点生态功能区有机农业生产效率产生了显著的影响。环境因素中,农民人均纯收入的增加有利于促使农机、耕地等资源的有效利用,但同时也导致化肥投入冗余增加;城镇化率的提高会降低耕地、劳动力、化肥、农药等使用效率,从而对有机农业生产效率产生不利影响;财政支出占GDP比重的增加有利于提高农机使用效率,但同时也导致化肥和农药投入冗余增加;粮食播种面积占耕地面积比重对有机农业生产效率产生了不利影响。剔除环境因素和随机误差的影响后,四川省重点生态功能区各县平均技术效率和规模效率有所下降,纯技术效率则略有提升。基于纯技术效率和规模效率,四川省重点生态功能区各县有机农业生产效率可分为"双高型""高低型""低高型"和"双低型"等4种类型。[结论]三阶段DEA模型有效剔除了环境因素和随机误差对有机农业生产效率的影响,估计的效率值更真实地反映了四川省重点生态功能区有机农业生产效率水平。针对四川省重点生态功能区各县有机农业生产效率的不同特征,应结合地方实际,通过扩大要素投入规模或改进要素配置效率和使用效率,提高有机农业生产效率。

The Price Impact of Lending Relationships

This study analyzes the impact of bank relationships on a firm's borrowing costs. We find that a firm's borrowing costs decrease with relationship strength, proxied by the share of bank debt provided by the lender. Borrowing costs, however, rise with relationship length. While the increase over time is weak on average, bank‐dependent borrowers face a substantial premium after several relationship years. Switching the lender initially leads to only a small price discount on average. However, the discount is considerable for borrowers that switch and had a strong relationship with their previous lender. Our results suggest that close lending relationships lead to benefits for the firm, but may also imply hold‐up costs in the long term.     

Migration,Unemployment, and Skill Downgrading

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.
