Understanding the dynamics between supervisor‐follower social capital,work engagement,and employees' creative work involvement

This study examines the previously unexplored mediating role of work engagement in the link between creative work involvement and the relational resources embedded in supervisor‐follower exchanges. We studied three relational resources inherent to the exchanges between followers and their supervisors: trust in supervisor, goal congruence, and relationship informality. Data were captured from IT professionals working at four well‐established IT companies in Ukraine. The findings show that relationship informality and goal congruence positively affect employees' creative work involvement, yet these effects are less pronounced when controlling for work engagement. The significance and implications of these findings for research and practice are discussed. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd.     

浅析Java 8中的集合遍历

Java平台提供了多种方式遍历对象的集合，其中包括今年3月19日发布的Java 8中引入的新特性。本文回顾了迭代器，着重分析了主动式迭代器和被动式迭代器之间的差异，研究了Java 8的foreach（）方法和Stream API如何改进和并行化Java迭代器的行为，然后对主动迭代、流和并行流这三种方法进行了性能比较。总之，Java 8的迭代器可读性更好，不易出错，也更容易并行化。     

新准则下的资产减值

新准则颁布之前,我国没有专门的资产减值准则,新《企业会计准则第8号—资产减值》,对资产减值作出了更具体的规范,有了较大的完善与进步,但在实施过程中仍暴露了一些不足方面。本文通过阐述我国资产减值准则的适用范围、基本特点、实施过程中存在的问题及解决途径,使我们对资产减值准则中的重点和难点问题有一个更全面和清晰的认识。     

Has SOX Enhanced Non–Big 4 Auditors' Ability to Deal with Client Pressure?

We investigate whether non–Big 4 auditors have enhanced their ability to resist client pressure over accrual reporting following the Sarbanes‐Oxley Act (SOX). Regressing abnormal accruals on proxies for economic bonding, we find that changes in the association, defined as (Post–Pre), are significantly negative, implying an improvement in auditor independence after SOX. Among non–Big 4 auditors, only Tier 3 auditors compromised reporting objectivity before SOX, but neither Tier 2 nor Tier 3 auditors yielded to client pressure after SOX. Evidence that these two groups of non–Big 4 auditors differ in the way they cope with client pressure in a loose regulatory regime highlights the importance of assessing the efficacy of SOX separately for subsets of auditors and contributes to an understanding of the underresearched, but inherently important, segment of the audit market served by non–Big 4 auditors. Further analysis indicates that the low pre‐SOX audit quality observed in the full sample is driven by non–PCAOB registrants.     

Adverse selection in credit markets and regressive profit taxation

In many countries, taxes on businesses are less progressive than labor income taxes. This paper provides a justification for this pattern based on adverse selection that entrepreneurs face in credit markets. Individuals choose between becoming entrepreneurs or workers and differ in their skill in both of these occupations. I find that endogenous cross-subsidization in the credit market equilibrium results in excessive (insufficient) entry of low-skilled (high-skilled) agents into entrepreneurship. This gives rise to a corrective role for differential taxation of entrepreneurial profits and labor income. In particular, a profit tax that is regressive relative to taxes on labor income restores the efficient occupational choice.     

Investment dynamics with common and private values

We study a dynamic investment game with two-dimensional signals, where each firm observes its continuously distributed idiosyncratic cost of investment and a discrete signal correlated with common investment returns. We demonstrate that the one-step property holds and provide an equilibrium existence/characterization result. “Reversals” are possible, where a large number of firms investing in a given round becomes bad news about investment returns. Welfare is compared to static and rigid-timing benchmarks, and computed for large economies.     

Information aggregation in financial markets with career concerns

What are the equilibrium features of a dynamic financial market in which traders care about their reputation for ability? We modify a standard sequential trading model to include traders with career concerns. We show that this market cannot be informationally efficient: there is no equilibrium in which prices converge to the true value, even after an infinite sequence of trades. We characterize the most revealing equilibrium of this game and show that an increase in the strength of the traders' reputational concerns has a negative effect on the extent of information that can be revealed in equilibrium but a positive effect on market liquidity.     

Investment responses to Japanese tax reforms: A cross-industry comparison

This paper examines the investment responses to past Japanese tax reforms for individual industries. To identify the tax effect, this paper estimates investment functions by using a covariate of the change in tax-adjusted q caused by tax reform. This method alleviates the measurement error problem and enables the derivation of estimates indicating the valid adjustment cost of investment. Moreover, the findings suggest that firms’ investment responded significantly to tax reforms in the 1980s in general. Also, investments of only a few industries responded to those in the late 1990s, implying that the manner of investment response slightly differs among industries.     

Expenditure Inequality in Indonesia, 2008–2010: A Spatial Decomposition Analysis and the Role of Education

Based on the 2008–2010 Susenas panel data, this study examines expenditure inequality from spatial perspectives in Indonesia, using three decomposition methods: (i) a conventional Theil index decomposition; (ii) an alternative Theil index decomposition proposed by Elbers et al. (2008); and (iii) the Blinder?Oaxaca decomposition. Our results show that overall inequality in per capita expenditure increases between 2008 and 2010, which coincides with a rising trend in the official Gini coefficient. The contribution of inequality within urban and rural areas to total inequality is larger than that of inequality between urban and rural areas. Looking within urban and rural areas, urban inequality is significantly higher than rural inequality. Java‐Bali in particular records very high urban inequality. Overall, urban inequality increases, urban–rural inequality remains stable, rural inequality decreases, and inequality at the national level increases. Although urban–rural inequality has a relatively low share in overall inequality, the share is not small enough to ignore its impact. Furthermore, when using the alternative decomposition method, the contribution of urban–rural inequality increases substantially. The present study also found that educational differences appear to have played an important role in expenditure inequality within urban areas and between urban and rural areas.
