Economies of Resource Accumulation 资源积累经济
Pub Date : 2012-12-12 DOI: 10.2139/ssrn.2188284
Karel O. Cool, Ingemar Dierickx, Luís Almeida Costa
This paper discusses when firms may expect economies in the accumulation of resources (asset mass efficiencies). Specifically, we describe situations in which the accumulation of a resource benefits from a “success breeds success” dynamic that creates an exponentially growing gap between resource levels of early movers and imitators. Early movers can expect such an advantage where products or services have high evaluation costs, durability, trial costs, network value and cost, impulse characteristics, and dependence on complementary products. Where the accumulation of one resource depends on the level of another resource, accumulation economies may also be expected. The mechanisms are illustrated using stylized stocks-flows simulations with the iThink software.
本文讨论了企业在资源积累(资产质量效率)中何时可以预期经济。具体来说,我们描述的情况是,资源的积累受益于“成功孕育成功”的动态,这种动态会在先行者和模仿者的资源水平之间造成指数级增长的差距。如果产品或服务具有较高的评估成本、耐用性、试用成本、网络价值和成本、冲动特性以及对互补产品的依赖,那么先行者可以期望获得这样的优势。当一种资源的积累依赖于另一种资源的水平时,积累经济可能也会出现。这些机制是用iThink软件的程式化股票流动模拟来说明的。

Pub Date : 2012-08-31 DOI: 10.2139/ssrn.2139385
Karel O. Cool, Ingemar Dierickx, Luís Almeida Costa
This paper discusses the concept of time compression diseconomies and its importance to the sustainability of competitive advantage. It focuses on a key driver of time compression costs, the time-dependency of resource accumulation, and illustrates the effects of three characteristics of this accumulation process (productivity, cycle time and absorption constraints). The effects are illustrated using a stylized stocks-flows simulation with the iThink software.

Group Decisions Under Ambiguity: Convergence to Neutrality 模糊性下的群体决策:趋同到中立
Pub Date : 2012-04-16 DOI: 10.2139/ssrn.2040655
Steffen Keck, Enrico Diecidue, D. Budescu
This paper focuses on decisions under ambiguity. Participants in a laboratory experiment made decisions in three different settings: (a) individually, (b) individually after discussing the decisions with two others, and (c) in groups of three. We show that groups are more likely to make ambiguity-neutral decisions than individuals, and that individuals make more ambiguity-neutral decisions after discussing the decisions with others. This shift toward higher ambiguity neutrality in groups and after a group discussion is associated with a reduction in the rates of both ambiguity aversion and ambiguity seeking. We suggest that the results might be driven by effective and persuasive communication that takes place in groups.
本文主要研究模糊情况下的决策问题。在一项实验室实验中,参与者在三种不同的环境下做出决定:(a)单独做出决定,(b)与另外两个人讨论决定后单独做出决定,(c)三人一组。我们发现,群体比个人更容易做出模糊中立的决策,而个人在与他人讨论决策后会做出更多模糊中立的决策。在小组中以及小组讨论后,这种向更高的模糊性中立的转变与模糊性厌恶和寻求的比率降低有关。我们认为,这些结果可能是由有效的、有说服力的群体沟通所驱动的。

The Impacts of Financial Policies on Inflation Rates in Sudan (1989-2010) 金融政策对苏丹通货膨胀率的影响(1989-2010)

The main focus of the present paper is to analyze the impacts of financial policy on inflation rates. The analysis depended on time series data and was divided into theoretical and applied analytical framework. An econometric model was utilized to reflect the relations between financial policy and inflation. Thus, more lights are shed on the fact that the first has great effects on the economic performance within the frame of economic policy and macroeconomic parameters. The analytical framework assumed that there are positive relationships between the independent variables of financial policy components represented in governmental expenditure and taxation and the dependant variable inflation. The results show that there is a negative correlation between total taxation and inflation rates. That means that raising taxes reduces inflation rate which is assumed by suppressing total consumption. However, in underdeveloped economies which already have entrenched poverty such consumption rates are minimized beyond the norms. Moreover, the results show that there is positive correlation between governmental expenditure and inflation rates. Deficit financing is a futile solution for the government to cover gaps between actual resources and the required ones. That instigates the conclusion that reducing inflation rates process should start by minimizing governmental expenditures and adopting austerity measures. The results coincides with the economic theory whereas inflation is correlated with the budgetary formulation which depends on deficit financing factor that may create real gaps between assumed and actual resources for the public budget.
本文的主要重点是分析金融政策对通货膨胀率的影响。分析依赖于时间序列数据,分为理论分析框架和应用分析框架。运用计量经济模型来反映财政政策与通货膨胀之间的关系。因此,更多地揭示了这样一个事实,即第一个因素在经济政策和宏观经济参数的框架内对经济表现有很大影响。分析框架假设政府支出和税收所代表的财政政策组成部分的自变量与因变量通货膨胀之间存在正相关关系。结果表明,总税收与通货膨胀率之间存在负相关关系。这意味着提高税收可以降低通货膨胀率,这是通过抑制总消费来假设的。然而,在已经根深蒂固的贫穷的不发达经济体中,这种消费率被降到最低,超出了标准。结果表明,政府支出与通货膨胀率之间存在正相关关系。赤字融资是政府弥补实际资源与所需资源之间差距的一种徒劳的解决方案。这促使人们得出结论,降低通货膨胀率的过程应该从最小化政府支出和采取紧缩措施开始。结果与经济理论一致,而通货膨胀与预算制定相关,预算制定取决于赤字融资因素,这可能会在公共预算的假设资源和实际资源之间造成真正的差距。

Filling or Abusing the Institutional Void? Ownership and Management Control of Public Family Businesses in an Emerging Market 填补还是滥用制度空白?新兴市场公共家族企业的所有权与管理控制
Pub Date : 2012-02-14 DOI: 10.2139/ssrn.2005101

Despite increased attention given to family firms in the theory of organization and management, the value of family governance in emerging markets is not clearly understood. We draw insights from agency and institutional economics perspectives to address the debate on whether family governance fills or abuses the void left by weaker market and legal institutions. We propose a dual focus on the pattern of family control and weak institutions to reconcile these opposed assessments. We analyze how various combinations of family control over ownership, strategy, and operations yield different benefits and costs for the operational performance of firms in the absence of strong market and legal institutions. The uneven development of market institutions across industries and the impact of independent directors reinforce the importance of separating different patterns of family control. We find support for our hypotheses when tested on a data set consisting of all publicly listed firms in Taiwan between 1996 and 2005. Our study contributes to a deeper understanding of family businesses in emerging markets, highlights the importance of weak institutions in shaping relative agency costs, and illuminates the differential effects of independent directors.
尽管在组织管理理论中,家族企业受到越来越多的关注,但在新兴市场中,家族治理的价值并没有得到明确的认识。我们从机构经济学和制度经济学的角度汲取见解,以解决关于家族治理是否填补或滥用较弱的市场和法律制度留下的空白的辩论。我们建议对家庭控制模式和薄弱的制度进行双重关注,以调和这些对立的评估。我们分析了在缺乏强大的市场和法律制度的情况下,家族对所有权、战略和运营的各种控制组合如何为企业的经营绩效带来不同的收益和成本。跨行业市场制度发展的不平衡以及独立董事的影响,强化了分离不同家族控制模式的重要性。在1996年至2005年台湾所有上市公司的数据集上,我们发现我们的假设得到了支持。我们的研究有助于加深对新兴市场家族企业的理解,强调了弱势制度在形成相对代理成本方面的重要性,并阐明了独立董事的差异效应。

Demand Uncertainty and Excess Supply in Commodity Contracting 商品契约中的需求不确定性与供给过剩
Pub Date : 2012-01-27 DOI: 10.2139/ssrn.1993003
Dana G. Popescu, S. Seshadri
We examine how different characteristics of product demand and market impact the relative sales volume in the forward and spot markets for a commodity whose aggregate demand is uncertain. In a setting where either the forward contracts are binding quantity commitments between buyers and suppliers or the forward production takes place before the uncertainty in demand is resolved, we find that a combination of factors that include market concentration, demand risk, and price elasticity of demand will determine whether a commodity will be sold mainly through forward contracts or in the spot market. Previous findings in the literature show that when participants are risk neutral, the ratio of forward sales to spot sales is a function of market concentration alone; also, the lower the concentration, the higher this ratio. These findings hold under the assumption that demand is either deterministic or, if demand is uncertain, all production takes place after uncertainty is fully resolved and production plans can be altered instantaneously and costlessly. In our setting, however, we find that even a low level of demand risk can reverse the nature of supply in a highly competitive (low concentration) market, by shifting it from predominantly forward-driven to predominantly spot-driven supply. In markets with high concentration, the price elasticity of demand will determine whether the supply will be predominantly spot-driven or forward-driven. Our analysis suggests various new hypotheses on the structure of supply in commodity markets. This paper was accepted by Martin Lariviere, operations management.
我们研究了产品需求和市场的不同特征如何影响总需求不确定的商品在远期和现货市场的相对销售量。无论是远期合约是买方和供应商之间的约束性数量承诺,还是在需求不确定性解决之前进行远期生产,我们发现,市场集中度、需求风险和需求价格弹性等因素的组合将决定一种商品是主要通过远期合约还是在现货市场销售。先前的研究结果表明,当参与者是风险中性时,远期销售与现货销售的比率仅是市场集中度的函数;同样,浓度越低,这个比值越大。这些发现是在需求是确定性的假设下成立的,或者,如果需求是不确定的,那么所有的生产都是在不确定性完全消除之后进行的,生产计划可以在瞬间无成本地改变。然而,在我们的设定中,我们发现即使是低水平的需求风险也可以通过将其从主要的前瞻性驱动转变为主要的现货驱动,从而扭转高度竞争(低集中度)市场中的供应性质。在高度集中的市场中,需求的价格弹性将决定供应主要是现货驱动还是远期驱动。我们的分析提出了关于商品市场供给结构的各种新假设。这篇论文被运营管理的Martin Lariviere接受。

Identity Challenges of Women Leaders: Antecedents and Consequences of Identity Interference 女性领导者的身份挑战:身份干扰的前因后果
Pub Date : 2011-12-21 DOI: 10.2139/ssrn.1975243
Natalia Karelaia, L. Guillén
We explore the antecedents and consequences of women leaders’ identity interference related to the perceived conflict between their roles as both women and leaders. Drawing on identity development and organizational demography research, we propose that leadership experience reduces women leaders’ identity interference, whereas women’s numerical underrepresentation in organizations exacerbates it. Moreover, we hypothesize that identity processes related to collective self-esteem—personal regard for one’s collective identity and the perception of others’ views of it—mediate these effects. A sample of 722 women leaders representing a diverse range of countries and industries supported our hypotheses. We also demonstrate that identity interference reduces the psychological well-being of women leaders and undermines their affective motivation to lead. In contrast, perceived conflict between leader and female identities enhances women’s sense of duty to assume leadership roles. Importantly, women leaders’ personal regard for their female identity buffers the detrimental effect of identity interference on life satisfaction. We discuss the implications of our results for women’s advancement in organizations and the development of their identity as leaders.
我们探讨了女性领导者身份干扰的前因和后果,这些干扰与女性角色和领导者角色之间的感知冲突有关。根据身份发展和组织人口统计学研究,我们提出领导经验减少了女性领导者的身份干扰,而女性在组织中的人数不足则加剧了这种干扰。此外,我们假设与集体自尊相关的认同过程——个人对集体认同的关注和他人对集体认同的看法——介导了这些影响。来自不同国家和行业的722名女性领导人的样本支持了我们的假设。我们还证明,身份干扰降低了女性领导者的心理健康,破坏了她们领导的情感动机。相反,领导者和女性身份之间的冲突增强了女性承担领导角色的责任感。重要的是,女性领导者对女性身份的个人尊重缓冲了身份干扰对生活满意度的有害影响。我们讨论了我们的结果对女性在组织中的进步和她们作为领导者的身份发展的影响。

Venturing into New Territory: Career Experiences of Corporate Venture Capital Managers and Practice Variation 开拓新领域:企业风险投资经理的职业经验与实践变化
Pub Date : 2011-12-08 DOI: 10.2139/ssrn.1969861
V. Gaba, Gina Dokko
When organizations adopt new practices, the practices are often modified to fit the new context. We argue that managers who implement new practices modify them, and that the extent of practice variation is determined by these managers’ career experience with the practice itself, and career experience that enables fit assessment between the practice and the adopting firm. We test these arguments by observing information technology firms’ modification of venture capital practices within corporate venture capital units. This study contributes to diffusion research by developing and testing a framework for understanding the role of individuals in practice variation.
当组织采用新的实践时,实践经常被修改以适应新的环境。我们认为,实施新实践的管理者对新实践进行了修改,实践变化的程度取决于这些管理者与实践本身的职业经验,以及能够对实践与采用实践的企业之间的契合度进行评估的职业经验。我们通过观察信息技术公司在公司风险投资部门内对风险投资实践的修改来检验这些论点。本研究通过开发和测试一个框架来理解个体在实践变化中的作用,从而有助于扩散研究。

Partnering with Competitors - An Empirical Analysis of Airline Alliances and Multimarket Competition 与竞争者合作——航空公司联盟与多市场竞争的实证分析
Pub Date : 2011-11-10 DOI: 10.2139/ssrn.1761211
Jun Li, Serguei Netessine
Competition has become an important theme in the operations management literature and, according to recent theoretical and empirical work, the key finding is that firms tend to overstock or overproduce under competition. Following this prediction, one would expect that, after airlines start a multifaceted collaboration by forming an alliance, their networks would be consolidated and capacity redundancies would be eliminated, as intensity of competition decreases among alliance partners. Surprisingly, we find exactly the opposite: in the post-alliance era, alliance partners seek to overlap their networks more and they increase capacities on the markets in which two partners are already present. At the same time, average prices in those markets increase by about $11 per one-way segment coupon. We explain these results using predictions based on the theory of multimarket competition: as firms seek out opportunities to establish multimarket contact to strengthen mutual forbearance, they have incentives to increase overlap even though this decision may not seem optimal or efficient locally or in the short term. We examine other plausible competing mechanisms built on theories of capacity and service competition and commonly cited benefits of airline alliances but ultimately we conclude that our findings are most likely driven by the multimarket competition. This paper therefore underscores the importance of going beyond simple bilateral competition models whose predictions may not hold when firms compete operationally in multiple markets, a phenomenon which is widespread in many operations-intensive industries.
竞争已成为运营管理文献中的一个重要主题,根据最近的理论和实证工作,关键发现是企业在竞争下往往会积压或生产过剩。根据这一预测,人们可以预期,在航空公司通过组建联盟开始多方面的合作后,随着联盟伙伴之间竞争的激烈程度降低,它们的网络将得到巩固,运力冗余将被消除。令人惊讶的是,我们发现情况恰恰相反:在后联盟时代,联盟伙伴寻求更多地重叠他们的网络,并在两个合作伙伴已经存在的市场上增加运力。与此同时,这些市场的单程票票平均价格上涨了约11美元。我们使用基于多市场竞争理论的预测来解释这些结果:当企业寻找机会建立多市场联系以加强相互容忍时,它们有动机增加重叠,即使这个决定在局部或短期内似乎不是最优或有效的。我们研究了基于容量和服务竞争理论的其他合理的竞争机制,以及通常被引用的航空公司联盟的好处,但最终我们得出结论,我们的发现最有可能是由多市场竞争驱动的。因此,本文强调了超越简单的双边竞争模型的重要性,当企业在多个市场上进行运营竞争时,这种模型的预测可能不成立,这种现象在许多运营密集型行业中普遍存在。

We explain these results using predictions based on the theory of multimarket competition: as firms seek out opportunities to establish multimarket contact to strengthen mutual forbearance, they have incentives to increase overlap even though this decision may not seem optimal or efficient locally or in the short term. We examine other plausible competing mechanisms built on theories of capacity and service competition and commonly cited benefits of airline alliances but ultimately we conclude that our findings are most likely driven by the multimarket competition. This paper therefore underscores the importance of going beyond simple bilateral competition models whose predictions may not hold when firms compete operationally in multiple markets, a phenomenon which is widespread in many operations-intensive industries.","PeriodicalId":122208,"journal":{"name":"INSEAD Working Paper Series","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131134502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide a critical review of the process called the “internationalization of higher education institutions” (HEI) with a closer look at the case of business schools. After offering an alternative definition of this phenomenon and examining the forces that drive international initiatives, we explain what we call the “internationalization paradox”: the observation that despite evidence that many of these initiatives fail to deliver what they promise, they nevertheless remain at the top of the agenda of heads of HEIs. We then develop a framework that identifies alternative models of internationalization. Based on this framework we sketch out a model of the truly global HEI whose mission is to learn from the world rather than teach the world what the institution knows. Our central thesis is that it is unlikely that HEIs will be able to transform themselves into truly global HEIs because of historical and organizational barriers rather than a shortage of resources or a lack of visionary leadership. We conclude that most HEIs should refrain from claiming that their aim is to become global institutions. They should instead focus on the successful implementation of an import-export model of internationalization that calls for initiatives such as the internationalization of the curriculum, the creation of student and faculty exchange programs, and the participation in international academic and research partnerships. Any attempt to transform themselves into truly global institutions is unlikely to succeed and may divert them from their fundamental mission to educate their home-based students and help them become effective global citizens.
我们对所谓的“高等教育机构国际化”(HEI)过程进行了批判性回顾,并对商学院的案例进行了更深入的研究。在对这一现象给出了另一种定义,并考察了推动国际倡议的力量之后,我们解释了我们所谓的“国际化悖论”:尽管有证据表明,许多这些倡议未能实现它们的承诺,但它们仍然是高等教育机构负责人议程的首要任务。然后,我们开发了一个框架来识别国际化的替代模型。基于这一框架,我们勾勒出一种真正的全球性高等教育模式,其使命是向世界学习,而不是向世界传授该机构所知道的东西。我们的中心论点是,由于历史和组织障碍,而不是资源短缺或缺乏有远见的领导,高等教育机构不太可能将自己转变为真正的全球性高等教育机构。我们得出的结论是,大多数高等教育机构不应宣称它们的目标是成为全球性机构。相反,他们应该把重点放在成功实施一种国际化的进出口模式上,这种模式呼吁诸如课程国际化、创建学生和教师交流项目以及参与国际学术和研究伙伴关系等举措。任何将自己转变为真正的全球机构的尝试都不太可能成功,而且可能会使它们偏离自己的基本使命,即教育以家庭为基础的学生,帮助他们成为有效的全球公民。
