Age-specific dynamic labor demand and human capital investment

To study the optimal age-specific labor demand and human capital investment at the firm level we extend the standard dynamic labor demand model by introducing ‘age’ as a second dynamic variable and distinguish between two types of workers: ‘low skilled’ and ‘high skilled’. Applying an age-structured optimal control model we derive qualitative features of the optimal age-specific hiring and training effort. For the case of a linear revenue and production function we prove that firms do not anticipate changes in adjustment costs in their optimal decisions. This result no longer holds if a nonlinear revenue or production function is considered.     

管理创新的"力场"分析

管理创新是在各种力的交互作用下产生的一种不规则性活动,只有当管理创新的动力大于阻力并取得支配地位时,管理创新行为才可能发生.管理创新的动力主要来源于需求拉力、竞争压力、利益内驱力、科技推力及政策激励力五个方面,而管理创新的阻力则主要来源于人的因素、组织的因素以及物质技术条件等.只有明确管理创新的"力场"构成,才能有目的地增强动力、克服阻力,实现增"正"减"负",从而推动管理创新活动的顺利进行.

Communication externalities in cities

To identify communication externalities in French cities, we exploit a unique survey recording workplace communication of individual workers. Our hypothesis is that in larger and/or more educated cities, workers should communicate more. In turn, more communication should have a positive effect on wages. By estimating both an earnings and a communication equation, we find evidence of communication externalities. In larger and more educated cities, workers communicate more and in turn this has a positive effect on their wages. Depending on the estimates, we find that 13 to 22% of the effects of a more educated and larger city on wages percolate through this channel.     

The Effects of Auditor Social and Human Capital on Auditor Compensation: Evidence from the Italian Small Audit Firm Market

Abstract

This study examines whether social and human capital influence the compensation of individual auditors in the small audit firm market. We employ a sample of Italian auditors and use measures from the network and auditing literatures to capture their professional connections, representing social capital, and their industry expertise, representing human capital. Our findings show a positive and economically meaningful association between these individual attributes and auditor compensation. We run several tests to address potential endogeneity issues in our research design. Our results suggest that, in the small audit market, clients perceive as valuable those auditors with higher social and human capital, and as a result, are willing to pay a premium for these specific auditor attributes.     

Camouflaged Indicators of Earnings Management†

Abstract

We argue that, in response to increased scrutiny and greater attention to accruals versus sales, firms become more likely to engage in accrual conversion (AC) cash management aimed at aligning cash and accruals with earnings and sales (e.g. by factoring of receivables). In doing so, they reduce the statistical power of standard indicators of accrual-based earnings management – in effect, camouflaging their earnings management activity. This proposition is of interest because many influential papers on earnings management have utilized accrual-based indicators to reach their conclusions. Our results indicate that firms indeed became more likely to engage in AC cash management after the passage of the Sarbanes-Oxley Act (SOX), and that this tendency was particularly pronounced among firms with strong incentives (or enhanced ability) to perform and hide earnings management. In particular, our findings suggest that the post-SOX decrease in standard measurements of accrual-based earnings management, identified in prior research, is partially attributable to firms’ increased engagement in AC cash management activity.

加强社保基金管理，提高投资收益

2006年上海社保基金案东窗事发，涉案金额达百亿人民币，由于社保基金牵涉老百姓日后生计，关系到社会稳定，一时之间，该案成为社会关注的焦点。但不可否认，在我国社保资金存在巨大缺口的压力下，将社保基金用于投资赚取收益并没有错。这一案件提醒我们，不能因为社保基金的特殊性，就忽略社保基金的投资管理。随着我国社保基金规模不断变大，投资领域和方式的不断出新，加强社保基金投资管理，非常关键。     

对国有企业管理问题的深层思考

国有企业一直存在着对管理既重视又落后的矛盾现象。其主要原因就在于国有企业在管理思想、管理体制和管理模式等方面还存在着一系列问题。主要表现在思想上存在着将管理务虚化、庸俗化、条件化和理想化的误区；在管理体制上存在着经济组织行政化、管理制度不规范的现象；在管理模式上存在着靠感觉行事、靠经验管理的粗放型色彩。这些深层次的矛盾和问题，直接影响着国有企业的经济效益和市场竞争能力。     

资源约束与地区经济收敛——基于资源稀缺性与资源配置力的考察

本文从资源稀缺性出发,提出并运用资源配置力这一新的分析工具,对2003年以来中国所面临的经济增长、资源约束与区域经济变动状况作了分析。结果表明,市场供求关系变化导致资源稀缺的结构性变迁与地域性转移,使地区资源配置力与经济竞争力发展相应变动。东部沿海能源与矿产等资源短缺地区备受资源约束递增的压力;中西部尤其是能源与矿产等资源富集地区资源配置力与经济竞争力明显递增,从而出现地区经济收敛趋势。
