Neither an Authentic Product nor a Counterfeit: The Growing Popularity of Shanzhai Products in Global Markets

Counterfeits have been a longstanding concern to global brand manufactures. However, recently, a new product category that partly imitates and partly innovates under the term shanzhai has entered into market. Shanzhai products mimic original leading brands through visual or functional similarities and may also provide additional features. Given this new copycat phenomenon, our study for the first time conceptually distinguishes shanzhai products from counterfeits, theoretically compares the values of consumers choosing shanzhai products versus counterfeits, and empirically tests such differences in one integrative model. Specifically, shanzhai buyers value product functional benefits more than counterfeit buyers, while counterfeit buyers value status consumption, yet experience less self‐clarity than shanzhai buyers. Our findings offer important implications for imitative innovation literature as well as for practitioners.     

Target‐Setting,Pay for Performance,and Quality Improvement: A Case Study of Ontario Hospitals’ Quality‐Improvement Plans

This study examines whether difficult targets and quality indicators in executives' pay‐for‐performance (P4P) plans affect performance. The impact of target‐setting and P4P plans on quality improvement in the public sector is unclear. The Ontario government initiated the Quality Improvement Plan (QIP), which requires hospitals to set targets for quality indicators annually and link executive pay to target achievement since 2011. Analyzing Health Quality Ontario's database and hospitals' 2012–2013 QIPs, this study shows greater quality improvement in hospitals with difficult targets than hospitals with easy targets or without assigned targets; however, the positive impact disappears for high‐performance hospitals relative to their peers. We find no significant effect of the use of quality indicators in executives' P4P plans on quality improvement. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

Defining Ownership: An empirical assessment of the ownership measures

Ownership is considered to be one of the crucial governance mechanisms; however, there have been no systematic attempts at validating the construct and measures used to operationalize ownership. We review the current understanding of ownership and the measures used by each perspective, namely blockholder/dispersed shareholder perspective, owner identity perspective, and aggregated ownership perspective. We thereafter critique each of these perspectives, offer hypotheses regarding their validity, and empirically assess each ownership measure vis‐à‐vis firm performance outcomes. We utilize a sample of 3,990 US firms to test our hypotheses and find no consistent results for the blockholder measure, or for the owner identity measure. However, the aggregated ownership measure consistently accounts for significant increases in explanation of variance in firm performance. Copyright © 2018 ASAC.

Geography and capital structure

We investigate the impact of geographic location on firms’ capital structure decisions. We find strong evidence that location of a firm influences its capital structure. In particular, we find that centrally located firms have lower leverage ratios than do remotely located ones. Moreover, consistent with the hypothesis that those remotely located firms face more severe adverse selection problems, the effect of geographic location on capital structure is more pronounced when information asymmetry is higher. We further examine alternative explanations of the negative relation between firm geographic proximity and capital structure and show that the financial constraint effect and industry clustering effect do not explain our results.

‘Get out of Traian Square!’: Roma Stigmatization as a Mobilizing Tool for the Far Right in Timişoara,Romania

Post‐communist Central and Eastern Europe has seen far right movements and parties gain considerable ground by drawing on nativist and ethnic claims to call for a return to an imagined past. In Romania, far right groups have been able to capitalize on a sense of injustice while also playing on historically negative feelings towards the Roma community. These patterns have been observed in Timi?oara, where the group Noua Dreapt? (New Right) has established a foothold over the past decade by emphasizing claims that blame the Roma for loss of built heritage and corruption in the administration of property restitution. The aims of this article are to examine the emergence of Noua Dreapt? and its use of Roma stigmatization, and to consider the ways in which extreme views are normalized by appealing to beliefs and perceptions. The findings of the article show that pre‐existing prejudices can be a powerful force that not only targets marginalized communities, but also challenges administrative practices and builds organizational support. At the level of the city, it is possible to identify the way in which these claims can be more precisely calibrated to draw on concerns that circulate within the community.     

Is job control always beneficial? Exploring its nonlinearity in creativity and in-role performance

This study draws on resource allocation theory to examine the relationship between job control and two kinds of job performance, namely employee creativity and in-role performance, as well as to investigate whether supervisor encouragement of creativity moderates these two potentially nonlinear relationships. To test the proposed model, we collected data from 234 employees in Indonesia. The results show that job control has an inverted U-shaped relationship with employee creativity, but a U-shaped relationship with in-role performance. Supervisor encouragement of creativity moderates both relationships, such that the control–creativity relationship becomes U-shaped, while the control–in-role performance relationship becomes inverted U-shaped when supervisor encouragement of creativity is high. Implications for managers on how to provide resources to employees are discussed.     

明代地方官府赋役核算体系的早期发展

明洪武到弘治年间,州县官府的赋役管理从基本不依赖核算向需要且能够进行核算的状态转变。洪武、永乐时期,在官府体系内部,只有田赋被部分地纳入核算管理,其他赋役征发则完全或绝大部分无法计量,也没有计划性。宣德以降,地方官员吸收民间粮里阶层分担赋役负担的经验,在此基础上进行旨在“均平”的改革,以确保赋役的可持续征发。在探索均平之道的过程中,不同地方官员多采取量化赋役负担、预定征收计划、将派征对象标准化并进行摊派核算的方式。其中,田赋额等开始扮演摊派对象的角色。这开启了州县层面赋役征收核算体系的发展之路,也导致府、州、县与户、工等部及布政使司之间产生了赋役核算信息不对称,出现了二重会计结构。     

Making an exciting brand big: Brand personality,logo size and brand evaluation

This research examines how brand personality (excitement) and logo size used in product design (big versus small) interacts in affecting consumer brand evaluation. We first demonstrate that combining a big logo and a high-excitement brand (versus a small logo combined with a high-excitement brand) leads to high processing fluency, further resulting in more favourable brand evaluation (Study 1). We then determine the consumption situation as a moderator of such an interaction effect: the influence of the big logo and high-excitement-brand combination on brand evaluation is significantly weakened in a private consumption situation (a T-shirt worn at home) compared to a public consumption situation (a T-shirt worn outside, Study 2a), and becomes insignificant for a private product category (slippers, Study 2b).     

论地勘单位财务风险管理

财务风险是资本价值经营的必然产物,地勘单位的财务风险主要是由于地勘单位的财务管理面对复杂多变的宏观环境及地勘单位财务风险的微观因素而产生的。地勘单位加强财务风险管理要采取建立健全财务风险预警机制、充分运用金融衍生工具、做好预算管理、加大内部控制力度、加强财务管理人员财务风险意识等措施。
