Exploiting a unique conditional disclosure mandate on management earnings forecasts (MEFs) in China, we examine the differential effects of voluntary and mandatory MEFs on the cost of debt. We find that firms providing voluntary MEFs have lower cost of debt than do mandatory forecasters and nonforecasters. The results of the channel analyses reveal that voluntary forecasters have greater commitment to voluntary MEFs in future periods than do mandatory forecasters and nonforecasters, and the precision, accuracy, and timeliness of MEFs are higher for voluntary forecasters than for mandatory forecasters. Additional analyses show that the differential effects of voluntary and mandatory MEFs on cost of debt are stronger for voluntary forecasters operating in opaque information environments, issuing high-quality and confirming forecasts, controlled by private shareholders, and operating in highly competitive product markets. Overall, our results indicate that, compared with mandatory MEFs, voluntary MEFs are more informative for credit investors, particularly for firms facing greater information risk and operating uncertainty.  相似文献

产学研协同创新是推动技术创新的一条重要路径,但创新成本分摊机制是影响产学研协同合作的一个重要问题。通过构建充分竞争市场下的多阶段博弈模型,从成本分摊机制角度探究了如何有效推进产学研协同创新。通过模型扩展与求解,获得成本分摊后的帕累托改善以及产学研协同创新的可行路径。结果表明:企业和学研方基于自身收益最大化而进行的成本分摊协商无法实现帕累托最优,而轮流出价博弈模型下的成本分摊形成机制能够有效改善各方收益,并使整体收益达到帕累托最优,因此是一条现实可行的帕累托改善路径,其中,各方获得的收益增量与耐心程度的对比有关。  相似文献

Abstract

This research investigates the persistence of price–cost margin (PCM) and technical efficiency (TE) of firms and the relation between these two factors in 44 subsectors of the Indonesian food and beverage industry in the period 1980–2014. Data envelopment analysis with a bootstrapping approach is applied to estimate TE. An autoregressive model, accounting for endogeneity, is applied to estimate the persistence coefficients of PCM and TE. A cross-sectional regression model is also applied to estimate the relation between the persistence of the PCM and the persistence of TE. The results show that for these food and beverage firms, high PCM and low TE persist. Furthermore, the persistence of PCM negatively affects the persistence of TE in the industry.  相似文献

Operating cash flow (CFO) asymmetric timeliness occurs when CFO reflects bad news more quickly than good news. We examine the presence and determinants of CFO asymmetric timeliness in Australia, where substantial differences in reporting requirements of cash flow components, in characteristics of listed companies and in the degree of conservative financial reporting produce contrasting findings to those in the United States. We find supportive evidence for the novel ‘sticky cost behaviour’ explanation and also the product-pricing strategy, but not the life cycle hypothesis. These findings are useful for investors and analysts concerned with forecasting the future values of companies.  相似文献

We investigate the effect of politically connected boards (both supervisory boards [SBs] and boards of directors [BODs]) on cost of debt and equity capital of listed companies in Indonesia which has established a two-tier corporate governance system. The results, based on 250 firms, suggest that companies with politically connected SBs experience lower cost of debt and equity capital, whereas politically connected BODs have no association with cost of either debt or equity. Furthermore, we find that family firms and firms belonging to business groups with politically connected SBs enjoy lower cost of debt and equity capital. Our main results are robust to alternative measures and to tests for endogeneity.  相似文献

We document a robust pattern of beta declining over the age of a firm. We find that changes in systematic risk via firm characteristics and life-cycle stages are insufficient to explain this pattern. Moreover, standard proxies for the quantity and quality of information also explain this pattern only partially. To fully explain this pattern we rely on the increasingly important role of familiarity in financial decision making: familiarity is a determinant of beta and firm age is a proxy for the degree of familiarity that investors feel toward individual stocks. To illustrate the implication of our findings, we document that when we control for firm age there is support for the CAPM and its use as an input for the cost of equity capital calculation.  相似文献

港口物流企业长期以来没有足够重视成本管理,现已存在诸多问题,如成本信息失真、经营责任制不够完善、成本与生产经营脱节等,所以改变现行成本管理方法显得尤为迫切。基于此,引入作业成本法为港口物流企业的成本管理提供理论和实践上的指导。结果表明,作业成本管理更具有优越性和精准性,适用于港口物流企业。最后根据结论,对港口物流企业如何进行成本管理提出了相关对策建议。  相似文献

本文运用双重差分法考察以《物权法》出台为标志的担保物权制度改革是否降低了企业的债务成本。实证结果显示,《物权法》出台后,与固定资产占比较高的企业相比,固定资产占比较低企业的债务成本显著降低。进一步,与《物权法》出台通过扩大可抵押资产范围、加强债权人保护等渠道降低企业债务成本的经济直觉一致,三重差分检验结果表明,担保物权制度改革对企业债务成本的降低作用表现出丰富差异性:其一,与法律制度环境较好地区相比,《物权法》对企业债务成本的降低作用在法律制度环境较差地区相对更大;其二,与金融市场化程度较高地区相比,《物权法》对企业债务成本的降低作用在金融市场化程度较低地区相对更大;其三,与融资约束较弱企业相比,对于融资约束较强的企业而言,《物权法》对债务成本的降低作用相对更强。这些基于中国经济实践的经验证据识别并揭示出了担保物权制度改革促使企业债务成本下降的作用机理,从而对有效缓解企业融资难、融资贵等问题具有借鉴意义。  相似文献

This paper investigates the driving factors behind the transition to a low carbon economy. Here, we offer a two-part analysis: First, we examine the factors leading to the current level of cleantech development. To do so, we examine the impact of country-level economic variables (real GDP, market return, and turnover) and country-level institutional variables on patent intensity. Results from this analysis show that cleantech patenting activity is fostered by a supportive institutional environment that promotes innovation and low-carbon development through carbon pricing policies, country-level public R&D expenditure and human capital. Second, we extend the notion of ‘path creation’ to map out different pathways for cleantech development on a country-level within a real options framework, and offer a corresponding valuation of cleantech patents. Our estimates of total wealth creation through the development of cleantech patents by 2050 range from US$10.16 to US$15.49 trillion dollars (13%–20% of the world GDP in 2017) with investment growth from US$2.93 to US$3.71 trillion (3.7%–4.7% of the world GDP in 2017). The results from our analysis suggest that market forces will drive the transition to a cleantech economy.  相似文献

在构建以国内大循环为主体、国内国际双循环相互促进的新发展格局下,高效协同的区域创新体系有助于将粤港澳大湾区三地建设成为具有全球影响力的科技创新中心。通过构建创新生态系统综合评价指标体系,采用耦合协调模型和空间计量模型,实证检验大湾区10个城市2007-2019年创新生态系统内部耦合协调水平、时空跃迁特征以及收敛性。研究发现,大湾区整体及各城市耦合协调度呈上升趋势,基本实现从失调衰退区到协调过渡区的转化,具体可划分为4个等级层次;大湾区创新生态系统协调耦合度存在显著的绝对β与条件β收敛趋势,即最终收敛于同一稳态水平,且城市间差距逐渐缩小。其中,经济发展水平、对外交流水平、人力资本水平对创新生态系统协调耦合度起显著正向作用。  相似文献
