我国天然气产业发展面临的不确定性因素

随着世界石油市场格局发生深刻变化,油价下行,国内GDP增速放缓,我国天然气市场发展的内外部条件正在发生变化。国内天然气生产能力、消费需求以及价格改革等因素存在不确定性,实现《能源发展战略行动计划(2014-2020年)》发展目标面临较大挑战。我国天然气行业已经具备一定的发展基础,但在产业政策导向、税收和价格调控、监管体系建设以及对技术创新的激励和支持等方面仍存在诸多问题。     

Labor Unions and Forms of Corporate Liquidity

We examine how the presence of labor unions affects a firm's choice of corporate liquidity between bank lines of credit and corporate cash holdings. We find that firms in industries with higher unionization rates hold a higher fraction of corporate liquidity in the form of bank lines of credit. We divide the firms into sub‐groups and find that this positive relationship holds for firms that are not in a state with right‐to‐work legislation and for firms that are financially constrained. Our findings are consistent with the hypothesis that a firm chooses the forms of corporate liquidity to take advantage of the bargaining benefits associated with bank lines of credit.     

Does reputation of sponsors matter in IPO? Evidence from Hong Kong

Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.     

Azéma martingales for Bessel and CIR processes and the pricing of Parisian zero‐coupon bonds

In this paper, we study the excursions of Bessel and Cox–Ingersoll–Ross (CIR) processes with dimensions . We obtain densities for the last passage times and meanders of the processes. Using these results, we prove a variation of the Azéma martingale for the Bessel and CIR processes based on excursion theory. Furthermore, we study their Parisian excursions, and generalize previous results on the Parisian stopping time of Brownian motion to that of the Bessel and CIR processes. We obtain explicit formulas and asymptotic results for the densities of the Parisian stopping times, and develop exact simulation algorithms to sample the Parisian stopping times of Bessel and CIR processes. We introduce a new type of bond, the zero‐coupon Parisian bond. The buyer of such a bond is betting against zero interest rates, while the seller is effectively hedging against a period where interest rates fluctuate around 0. Using our results, we propose two methods for pricing these bonds and provide numerical examples.     

Auditors' Responses to Workload Imbalance and the Impact on Audit Quality*

Using detailed data for fieldwork hours and audit hours by rank from audit engagements in Korea, we examine whether audits conducted under workload imbalance, proxied by busy‐season audits, impair audit quality, and how auditors adjust staff assignments for busy‐season audits. We generally find that busy‐season audits are associated with lower audit quality, and that audit firms reduce the involvement of senior auditors during busy‐season audits. In addition, the greater the involvement of senior auditors and junior auditors, the lesser the deterioration in audit quality. Finally, although there is no increase in interim audits in response to workload imbalance during busy seasons, increasing interim audits can mitigate the negative impact of busy‐season audits on audit quality. Our results are relevant to auditors and regulators, who have expressed concerns about the adverse effects of workload imbalance on audit quality.

Gender Diversity in the Boardroom and Risk Management: A Case of R&D Investment

Increasing gender diversity in the boardroom has been promoted as a way to enhance corporate governance and risk management. This study empirically examines whether boards with more female directors play a role in reducing R&D risk. We first show that female directors help to reduce the positive relationship between R&D investment and future performance volatility. We then report that firms with more gender-diverse boards exhibit a lower adverse effect of R&D on the cost of debt. These results are robust to endogeneity analysis, alternative measures of gender diversity and risky investment, and other sensitivity tests. Overall, our results suggest that female directors improve board effectiveness in risk management with respect to R&D investment.

产权流动是国有传媒机构改革的根本出路

产权流动是市场经济改革深化的重要形式之一,是按市场规律发展的必然趋势。通过国际视野的对照与案例分析可以看出,中国国有传媒机构的产权流动是一个急迫的现实问题,由于所有制的限制、行政干预过多等原因,国有传媒机构进行产权流动应将决策权、执行权和监督权分开而独立,探索国有传媒机构的产权改革,着力改变"发展惰性",进行有限创新,全面探索多元资本进入机制。
