Auditing Goodwill in the Post‐Amortization Era: Challenges for Auditors

The elimination of goodwill amortization in 2001 brought about significant change in how companies are required to account for goodwill. This change in accounting also brought with it new challenges for auditors, namely evaluating the reasonableness of management's assumptions related to goodwill valuation. In addition to introducing technical challenges, this task is particularly difficult given the misalignment in incentives it creates between managers who likely prefer to avoid recording an impairment and auditors who seek to minimize the bias in management's impairment testing. This study focuses on the consequences of the misaligned incentives that auditors face under the current goodwill assessment process. We find that the decision to record a goodwill impairment is associated with an increase in the probability of auditor dismissal. Consistent with the presence of significant friction with clients, our results also indicate that the likelihood of auditor dismissals is negatively related to the favorability of the impairment decision. Furthermore, we find that companies impairing goodwill prior to dismissing auditors subsequently employ auditors that are, on average, more favorable to clients in their impairment decisions.     

我国应对“非市场经济地位”问题的对策

我国的"非市场经济地位"间接地加大了我国应对反倾销的成本,为国外向我国征收高额反倾销税或确定倾销成立提供了便利,是国外对华滥用反倾销起诉的一个客观因素,但"非市场经济地位"并没有影响到我国外贸大局。就"非市场经济地位"问题的利弊得失,本文探讨了我国目前应对"非市场经济地位"问题的具体策略。     

THE IMPACT OF GREATER AUTONOMY ON EFFICIENCY OF WORK AND QUALITY OF SERVICES IN PUBLIC SERVICE PROVIDERS: A CASE OF VOCATIONAL EDUCATION INSTITUTIONS

ABSTRACT: The paper analyses impact of greater autonomy on efficiency of work and quality of services in public service institutions. Autonomy is one of the key principles of New Public Management that, according to the theory, increases performance in public service providers. However this assumption has been scarcely researched in practice. To narrow this gap, the experimental reform that implemented greater managerial and financial autonomy in 13 Lithuanian state vocational schools was chosen for research. In order to analyse the impact of autonomy after the reform, maximally similar institutions (those that underwent the reform and that did not) are compared using quantitative (incl. counterfactual analysis) and qualitative methods. The results indicate that institutions that have been reformed tend to have better efficiency and quality of services, even though this relationship is not causal. Moreover, the research challenges the notion that such results came from greater autonomy. Finally, the logic of the NPM of as to why more autonomous institutions perform better is also challenged.

Using choice experiments to value catchment and estuary health in Tasmania with individual preference heterogeneity*

Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of estuary values. The CE study described in this paper aims to analyse community preferences for NRM options in the George catchment, Tasmania. Catchment health attributes were: the length of native riverside vegetation; the number of rare native animal and plant species in the George catchment; and area of healthy seagrass beds in the Georges Bay, which was used as a measure of estuary condition. Mixed logit models with interactions between socio‐economic variables and the choice attributes were estimated to account for systematic and random taste heterogeneity across respondents. Results reveal considerable variation in preferences towards the attributes and show that value estimates are significantly impacted by the way in which we account for preference heterogeneity. Preference heterogeneity thus needs to be considered when estimating community willingness‐to‐pay for environmental changes. This study further shows little responsiveness to the presented changes in estuary seagrass area.     

试论我国现行预算会计的改革

预算会计作为我国会计体系的一个分支,与企业会计的发展相比,已到了必须改革的关键时刻.建立我国的政府与非营利组织会计体系,在政府会计中引入"权责发生制"等,是我国预算会计将面临的又一次重大改革.     

试论构建非公企业和谐劳动关系

在公有制为主体的条件下发展非公有制经济,是社会主义初级阶段生产力发展的客观要求.但是,在现实劳动关系中,非公企业不法经营、欺压劳工相当普遍,克扣、拖欠工资并造成企业员工的合法权益受侵犯的问题在某些地方还相当严重.在激烈的市场竞争中,是否构建和谐劳动关系,直接关系非公企业核心竞争力以及自身的生存与发展.构建非公企业和谐劳动关系,对于非公企业实现法治管理,以及发挥行业自律作用都有推进作用.非公企业劳动关系和谐模式的构建,可以划分为精神层、制度层和物质层.应从以下方面把握:建设和谐文化,培育和谐精神;诚实守信,不为欺诈行为;符合利益相关者的利益,实行民主管理;管理者与被管理之间相互尊重,以人为本;依靠和谐理念,增强管理的非权力影响.     

Flexibility in the gig economy: managing time on three online piecework platforms

Gig economy platforms seem to provide extreme temporal flexibility to workers, giving them full control over how to spend each hour and minute of the day. What constraints do workers face when attempting to exercise this flexibility? We use 30 worker interviews and other data to compare three online piecework platforms with different histories and worker demographics: Mechanical Turk, MobileWorks, and CloudFactory. We find that structural constraints (availability of work and degree of worker dependence on the work) as well as cultural‐cognitive constraints (procrastination and presenteeism) limit worker control over scheduling in practice. The severity of these constraints varies significantly between platforms, the formally freest platform presenting the greatest structural and cultural‐cognitive constraints. We also find that workers have developed informal practices, tools, and communities to address these constraints. We conclude that focusing on outcomes rather than on worker control is a more fruitful way to assess flexible working arrangements.     

混合股权制衡度与真实盈余管理行为

混合所有制改革形成了非国有股与国有股相互制衡的股权结构。通过研究国有企业中非国有股权和国有股权相互制衡的程度与真实盈余管理行为的关系发现：混合股权制衡度显著抑制了国有企业的真实盈余管理行为,但当国有性质股权占比小于非国有性质股权占比时上述抑制作用减弱。另外,参与混合所有制改革的金融类、外资类股权相比民营类股权制衡度,对真实盈余管理行为发挥了更显著的治理作用。机制检验发现,混合股权制衡一方面通过提升业绩,提高对真实盈余管理动机的抑制作用,从而缓解了真实盈余管理行为;另一方面通过提升内部控制对真实盈余管理的抑制作用,降低了真实盈余管理行为。以上结论有助于深化国有企业混合所有制改革,为提升混改中的审计监管质量提供参考。
