会计准则的产生与制定权归属的经济学解释——来自企业所有权理论的观点

本文从新制度经济学的企业所有权理论出发,对会计准则的产生及其制定权的归属提出经济解释。会计准则的产生与制定权的归属缘于降低交易费用的需要。为什么可以降低交易费用,有学者从索取权出发进行了分析,本文则从控制权的角度进行了讨论:为了遏制经理的“特定控制权收益”,政府拥有了会计准则的制定权,而经理仅拥有了在会计准则框架内作出会计判断的权力。本文认为控制权角度的解释在以股份公司为主的经济环境中是更加有力的。

Urban Economic Openness and IPO Underpricing

This paper represents a first attempt to employ a macroeconomic approach to explain the high and varying IPO underpricing within a single emerging market. We examine the empirical impact of trade openness on the short-run underpricing of initial public offerings (IPOs) using city-level data. Particularly, we argue that urban economic openness (UEO) has a significant impact on the productivity and on prices of both direct and indirect real estate due to productivity gains of companies in more open areas. This in turn positively affects the firm’s profitability, enhancing the confidence in local real estate markets and future company performance, hence decreasing the uncertainty of the IPO valuation. As a result, issuers have less incentive to underprice IPO shares. We use a sample of Chinese real estate IPOs, which offer a suitable laboratory thanks to their strong geographic investment patterns focused locally and a country with a highly heterogeneous openness across regions. Controlling for traditional firm- and issuing-specific characteristics of IPOs that are used for developed markets and Chinese-related features (i.e. listing location and state ownership), we find the evidence that companies investing in economically more open areas experience less IPO underpricing. Our results show great explanatory power and are robust to different specifications.

Assessment of innovation and foreign direct investment: An investigation of OECD countries

Using a panel cointegration method incorporating structural breaks and cross-sectional dependence, this paper explores the long-run equilibrium relationship between innovation and foreign direct investment (FDI) in 30 OECD countries. The results from the panel stationary test show that FDI and innovation variables follow a stationary process with several structural breaks over the period 1999–2018. The results also suggest an equilibrium relationship with structural breaks between FDI and innovation in OECD countries. The panel dynamic OLS model with breaks further reveals that FDI is positively associated with innovation performance and vice versa in OECD countries. Therefore, this paper sheds light on the relationship between FDI and innovation in OECD countries.     

KIBS企业—顾客交互创新中知识整合的权变机制

引入过程互依性和项目不确定性,探讨了KIBS企业-顾客交互创新中知识整合的权变机制。基于338份服务创新项目问卷数据进行实证研究,结果显示:在KIBS企业-顾客交互四要素中,除规则正式化负向影响外部知识整合以外,决策集体化、资源共享和任务协作均正向影响内、外部知识整合;过程互依性增强了规则正式化、决策集体化和任务协作对内部知识整合的影响,但对资源共享与内部知识整合间关系的调节作用不显著;项目不确定性增强了规则正式化、资源共享和任务协作对外部知识整合的影响,但对决策集体化与外部知识整合间关系的调节作用不显著。     

业绩考核制度如何影响央企现金持有?——基于《考核办法》第三次修订的准自然实验

本文基于2010—2017年我国A股上市公司数据,以十八大后推行的业绩考核办法优化修订为准自然实验,选用双重差分模型检验2013年新的《考核办法》实施对中央企业的现金持有的影响,研究发现:与不受该制度影响的民营企业相比,新的《考核办法》显著正向提升央企的现金持有水平,且这一结果均通过平行趋势、控制组调整、变量替换、PSM-DID和安慰剂检验等稳健性检验;通过机制分析发现,业绩考核制度通过发挥抑制央企因超额持现所诱发的过度投资而提升央企现金持有;进一步地,业绩考核还促使央企权衡增持的现金资源二次配置策略,缩减超额持现的股利支付且转而将其用于创新活动,进而提升中央企业现金持有价值。上述结果意味着,业绩考核制度既可以抑制过度投资的无效耗费行为促使央企增持现金,又将增持现金用于“多创新,少股利”的长期价值创造权衡配置,优化增持现金利用效率,提高企业创新能力,进而提升企业价值,这为十八大以来有关中央企业高质发展和国资监管体制建设而进行改革的政策预期效果提供经验证据,同时为进一步全面深化国资监管、积极深入推进业绩考核制度优化修订提供理论依据和经验证据。     

CLOSED FORM PRICING FORMULAS FOR DISCRETELY SAMPLED GENERALIZED VARIANCE SWAPS

Most of the existing pricing models of variance derivative products assume continuous sampling of the realized variance processes, though actual contractual specifications compute the realized variance based on sampling at discrete times. We present a general analytic approach for pricing discretely sampled generalized variance swaps under the stochastic volatility models with simultaneous jumps in the asset price and variance processes. The resulting pricing formula of the gamma swap is in closed form while those of the corridor variance swaps and conditional variance swaps take the form of one‐dimensional Fourier integrals. We also verify through analytic calculations the convergence of the asymptotic limit of the pricing formulas of the discretely sampled generalized variance swaps under vanishing sampling interval to the analytic pricing formulas of the continuously sampled counterparts. The proposed methodology can be applied to any affine model and other higher moments swaps as well. We examine the exposure to convexity (volatility of variance) and skew (correlation between the equity returns and variance process) of these discretely sampled generalized variance swaps. We explore the impact on the fair strike prices of these exotic variance swaps with respect to different sets of parameter values, like varying sampling frequencies, jump intensity, and width of the monitoring corridor.
