Value creation and business models: Refocusing the intellectual capital debate

There is currently significant debate worldwide regarding business reporting. The concept of the ‘business model’ has entered into the discourse, as has the concept of ‘integrated reporting’, adding to the established debate regarding accounting for intangible assets and, more generally, intellectual capital (IC). Despite the tradition of extensive interdisciplinary borrowing in accounting, relevant literatures on business models and on modern managerial perspectives on competitive advantage have, to date, largely been ignored within the accounting literature. The main contribution of this conceptual paper is to identify and discuss the key features of these literature strands and their linkage to contemporary debates on narrative reporting. These conceptual linkages between IC, value creation and business models are illustrated by means of interview evidence from eleven company cases. It is concluded that the business model concept offers a powerful overarching concept within which to refocus the IC debate. The concept is holistic, multi-level, boundary-spanning and dynamic. The analysis supports the current calls for integrated disclosure around the central business model story. Suggestions for future research are offered.     

American-style options in jump-diffusion models: estimation and evaluation

We propose dynamic programming coupled with finite elements for valuing American-style options under Gaussian and double exponential jumps à la Merton [J. Financ. Econ., 1976, 3, 125–144] and Kou [Manage. Sci., 2002, 48, 1086–1101], and we provide a proof of uniform convergence. Our numerical experiments confirm this convergence result and show the efficiency of the proposed methodology. We also address the estimation problem and report an empirical investigation based on Home Depot. Jump-diffusion models outperform their pure-diffusion counterparts.     

Expropriation risk and technology

This paper develops a unified framework to analyze the dynamics of firm investment in countries with poor legal enforcement. The firm's technology edge over the government generates endogenous property rights. Industry variation in the technology gap predicts a sectoral pecking-order of expropriations. Long-run investment distortions may be Pareto superior relative to persistent investment at the static optimum. The dynamics of investment and transfers depend on whether incentives (backloading) or efficiency (frontloading) concerns dominate at the initial division of surplus. An increase in government efficiency may reduce its welfare. The model provides a technology-driven rationale for the widespread use of conglomerate structures in emerging market countries.     

我国M_2/GDP的动态增长路径、货币供应量与政策选择

本文试图求解我国M2/GDP的动态增长路径,并对与此相关的金融政策选择进行分析。研究发现,我国M2/GDP的变动路径具有Logistic曲线的基本形状,将经历先加速上升后增长速度逐渐减缓,最终趋于稳定状态的变化过程。本文估算了我国M2/GDP的增长上限及其变化拐点。研究还发现,M2/GDP的上升并不必然意味着通胀压力加大,只有M2/GDP偏离动态增长路径时,才会对通货膨胀产生影响。据此本文估算了2005年货币供应量的合理区间。本文认为,应继续实施稳健货币政策,合理确定货币总量增长速度,继续推进体制性改革等措施确保经济金融的稳定运行。     

Markov regime-switching Beta-t-EGARCH

We suggest a Markov regime-switching (MS) Beta-t-EGARCH (exponential generalized autoregressive conditional heteroscedasticity) model for U.S. stock returns. We compare the in-sample statistical performance of the MS Beta-t-EGARCH model with that of the single-regime Beta-t-EGARCH model. For both models we consider leverage effects for conditional volatility. We use data from the Standard Poor’s 500 (S&P 500) index and also a random sample that includes 50 components of the S&P 500. We study the outlier-discounting property of the single-regime Beta-t-EGARCH and MS Beta-t-EGARCH models. For the S&P 500, we show that for the MS Beta-t-EGARCH model extreme observations are discounted more for the low-volatility regime than for the high-volatility regime. The conditions of consistency and asymptotic normality of the maximum likelihood estimator are satisfied for both the single-regime and MS Beta-t-EGARCH models. All likelihood-based in-sample statistical performance metrics suggest that the MS Beta-t-EGARCH model is superior to the single-regime Beta-t-EGARCH model. We present an application to the out-of-sample density forecast performance of both models. The results show that the density forecast performance of the MS Beta-t-EGARCH model is superior to that of the single-regime Beta-t-EGARCH model.

Transforming under deep uncertainty: A strategic perspective on risk management

Companies increasingly face the need for transformation in today’s rapidly changing business environment, characterized by major shifts in technology, regulation, and customer behavior. A lack of strategic risk insight and foresight leaves many incumbents insufficiently prepared in the face of such deep uncertainty. We argue that traditional risk management falls short because it predominantly focuses on strategy execution while leaving strategy formulation largely untouched. Moreover, an administrative-heavy risk management process can create strategic inertia and a misleading sense of control. In today’s dynamic business context, companies must not only increase the speed and impact of their strategy execution but also continuously explore the development of new strategies in response to disruptive events or emerging opportunities. Our research shows how leading companies develop a strategic risk management (SRM) capability to increase their resilience and agility in response to deep uncertainty. SRM takes a strategic, forward-looking perspective and focuses on strengthening processes, people, and practices for purposefully integrating risk into the strategy formulation process. This article offers a framework with three proven configurations of content and timing integration, risk management roles, and leading practices that enable effective SRM.     

Should sequels differ from original movies in pre-launch advertising schedule? Lessons from consumers' online search activity

Sequels have become a profitable strategy in the U.S. motion picture industry because of their strong name recognition. However, while the established positioning of a sequel may help insulate it from competing firms' advertising messages, its familiarity may cause moviegoers to be more easily satiated with advertising from the sequel. Therefore, this study examines how sequels differ from original concept movies in terms of their ad effectiveness. We focus our analysis on pre-launch periods, given these periods' importance in shaping the financial outcomes of motion pictures. We consider the weekly online search volume of a movie as a measure of consumer interest in it, and thus as an intermediate response to pre-launch advertising. We then develop a model that assumes ad effectiveness can decline, due to copy and repetition wearout, and increase, due to forgetting, over time. We find that copy wearout is greater for original movies, while repetition wearout and forgetting are greater for sequels. These findings suggest that sequels should allocate more in early pre-launch periods and less immediately before release, relative to originals, to maximize pre-launch consumer interest.     

核心企业治理能力对模块化组织价值创新的影响

模块化组织中核心企业治理能力直接关系到组织价值创新绩效。构建了核心企业治理能力影响模块化组织价值创新的概念模型,并将环境动态性作为调节变量引入该模型。基于268家以模块化方式运行的样本企业数据开展实证研究发现：核心企业治理能力所包含的系统设计能力、合作主导能力、关系协调能力和知识重构能力均对模块化组织价值创新产生了正向影响。其中,系统设计能力对组织价值创新的促进作用最大,其它依次为关系协调能力、知识重构能力和合作主导能力;在环境动态性的调节作用下,核心企业关系协调能力和知识重构能力会增强对组织价值创新的正向影响,而系统设计能力和合作主导能力会削弱对组织价值创新的正向影响。
