Unlike more stable industries, high-tech firms must constantly be in a strategy development phase. These companies are in desperate need of assistance in strategy formulation. This paper introduces a quantitative (rather than subjective) approach to help high-tech firms to understand their position in the technology adoption life cycle using some of the principles and tools of Chaos and Complexity theories. This approach is demonstrated by using data sets of three case studies in the hard drive, microprocessor, and server high-tech industries.  相似文献

We distinguish non-normality from non-linearity in G7 real exchange rate dynamics by correcting the critical values of the Kapetanios et al. [Kapetanios, G., Shin, Y., Snell, A., 2003. Testing for a unit root in the non-linear STAR framework. Journal of Econometrics, 112, 359–379] test for non-normality using the wild bootstrap. Our findings validate non-linear Purchasing Power Parity net of non-normality effects.  相似文献

This study investigates the impact of uncertainty shocks on macroeconomic activity in Korea. For this purpose, a Smooth Transition VAR model is employed to document the state-dependent dynamics of two distinct types of uncertainty shocks, namely, financial market based and news-based. When non-linearity is allowed to play a role in our model, quantitatively very different asymmetric dynamics are observed. Following inflation targeting, the responses tend to be smoother and less pronounced. Our empirical results support the view that the link between uncertainty and macroeconomic activity is clear over both recessions and expansions. Furthermore, the impact of uncertainty shocks is more pronounced when economic activity is depressed especially after shocks originate from the financial market, and not from news-based policy uncertainty in Korea.  相似文献

In dynamic economic models derived from optimization principles, the forward equilibrium dynamics may not be uniquely defined, while the backward dynamics is well defined. We derive properties of the global forward equilibrium paths based on properties of the backward dynamics. We propose the framework of iterated function systems (IFSs) to describe the set of forward equilibria and apply the IFS framework to a one- and a two-dimensional version of the overlapping generations (OLG)-model. We show that if the backward dynamics is chaotic and has a homoclinic orbit (a “snap-back repeller”), the set of forward equilibrium paths converges to a fractal attractor. Forward equilibria may be interpreted as sunspot equilibria, where a random sunspot sequence determines equilibrium selection at each date.  相似文献

This paper argues that UK monetary policymakers did not respond to the inflation rate during most of the “Great Moderation” that ran from the early 1990s to the mid-2000s. We derive a generalisation of the New Keynesian Phillips curve in which inflation is a non-linear function of the output gap and show that the optimal response of the policy rule to inflation depends on the slope of the Phillips curve; if this is flat, manipulation of aggregate demand through monetary policy does not affect inflation and so policymakers cannot affect inflation. We estimate the monetary policy rules implied by a variety of alternative Phillips curves; our preferred model is based on a Phillips curve that is flat when output is close to equilibrium. We find that policy rates do not respond to inflation when the output gap is small, a situation that characterised most of the “Great Moderation” period.  相似文献

Economic orthodoxy has but a minimal interest in methodology.Heterodoxy is suspicious of dialectics. As exemplified recentlyin a book by John Rosenthal, even Marxism likes to eschew thenotion of any more than a residual Hegelian influence in Marxand Marxist discourse. Bouncing off Rosenthal's argument, thispaper argues for the legitimacy of a pragmatic post-Hegelianmethod for critical political economy.  相似文献

The art of rhetoric may be defined as changing other people's minds (opinions, beliefs) without providing them new information. One technique heavily used by rhetoric employs analogies. Using analogies, one may draw the listener's attention to similarities between cases and to re-organize existing information in a way that highlights certain regularities. In this paper we offer two models of analogies, discuss their theoretical equivalence, and show that finding good analogies is a computationally hard problem.  相似文献

Compendious and thorough solutions to the existence of a linear price equilibrium problem, the second welfare theorem, and the limit theorem on the core are provided for exchange economies whose consumption sets are the positive cone of arbitrary ordered Fréchet spaces—dispensing entirely with the assumption that the vector ordering of the commodity space is a lattice. The motivation comes from economic applications showing the need to bring within the scope of equilibrium theory vector orderings that are not lattices, which arise in the typical model of portfolio trading with missing options. The assumptions are on the primitives of the model. They are bounds on the marginals of non-linear prices and for ω-proper economies they are both sufficient and necessary.  相似文献

The paper offers a novel interpretation and affirmation of theopening arguments of Capital, answering the fundamental butneglected question of why labour is the substance of value.Marx's arguments require that two philosophical threads, oftenseparated in the literature on value, be woven together. Theargument that value is the intrinsic ‘content’ makingcommodities exchangeable employs the thread of realism. Theargument that abstract labour is the emergent ‘socialsubstance’ of value employs the thread of dialectics.This interpretation develops the materialist and dialecticalphilosophy of E.V. Ilyenkov and deepens the approach to valuetheory initiated by Ben Fine.  相似文献

突破性创新是刺激技术跨越发展,推动产业转型升级的重要引擎,揭示其形成原理为攻克关键技术“卡脖子”问题提供了理论借鉴。基于突变理论凝练出突破性创新形成机理模型,认为突破性创新“积累-演化-临界-跃迁”的形成路径主要取决于内外部知识资源的聚合程度,从知识协同视角出发构建动力学模型以系统性地揭示知识资源到创新突破的动态过程。研究发现:外部知识资源的顺利引入是企业实现突破性创新的首要驱动因素,这对解决企业突破性创新的路径依赖和资源约束问题具有重要意义;吸收能力与聚合能力是推动企业形成突破性创新的关键性能力,然而,过高的组织记忆和知识惯性会僵化组织运营模式,遏制突破性创新的形成。研究结论为企业成功实施突破性创新提供了可操作的方法论,有助于技术行为从原始技术轨道成功过渡到新技术轨道。  相似文献

金融发展的倒U型增长效应与最优金融规模   总被引:2,自引:0,他引:2  
金融发展能够促进经济增长,但是其作用是非线性的。由于金融发展是有成本的,当金融过度发展时,其机会成本将大于潜在的收益,反而会阻碍经济增长。因此,经济中存在最优的金融发展规模。本文用金融部门就业占总就业的比重作为度量金融发展的指标,为避免内生性偏误,实证研究采用系统的GMM进行估计。结果表明:金融发展对经济增长的影响不是线性的,而是一个倒U型。潜在的最优金融规模主要由经济发展水平和人力资本存量决定。  相似文献

利用尖点突变理论来解释知识型员工组织承诺演化的动力学机制及其特征,把组织承诺作为状态变量,把能有效预测组织承诺的工作满意度和组织支持作为控制变量,针对武汉IT企业调研数据,利用cuspfit软件定量地拟合出了尖点突变模型。通过分析发现,工作满意度作为正则因子、组织支持作为分歧因子,共同影响组织承诺的突变机制:①组织承诺由建立到破坏的突变是源于工作满意度和组织支持变量穿过分歧集合时产生的自组织相变;②承诺一旦被破坏就很难重新建立起来,是源于这种突变机制的滞后效应;③当工作满意度和组织支持取值在分歧集合内部时,组织承诺演化均衡态的选择(建立或者破坏)取决于员工承诺的初始水平。  相似文献

The aim of this paper is to analyze the selection of routines inside an organizational structure characterized by different cognitive representations and facing hierarchical pressure leading to either truce or conflict. After a brief discussion of the role of hierarchy and the related problems of organizational practice selection in the evolutionary literature, we model the interactions between different groups within a firm trying to interfere with its coordination mechanisms in order to support their own practices. Numerical simulations highlight the different learning abilities present in various organizational set-ups and their related knowledge distribution. It is shown that networking designs are the most profitable organizational configurations because of their dynamics of learning, though they are very sensitive to the truce problem.JEL Classification: L14, L20, L22, B52, D83Correspondence to: Nathalie Lazaric  相似文献

Nash equilibrium is often interpreted as a steady state in which each player holds the correct expectations about the other players' behavior and acts rationally. This paper investigates the robustness of this interpretation when there are small costs associated with complicated forecasts. The model consists of a two-person strategic game in which each player chooses a finite machine to implement a strategy in an infinitely repeated 2×2 game with discounting. I analyze the model using a solution concept called Nash Equilibrium with Stable Forecasts (ESF). My main results concern the structure of equilibrium machine pairs. They provide necessary and sufficient conditions on the form of equilibrium strategies and plays. In contrast to the “folk theorem,” these structural properties place severe restrictions on the set of equilibrium paths and payoffs. For example, only sequences of the one-shot Nash equilibrium can be generated by any ESF of the repeated game of chicken.  相似文献

The aim of this paper is to analyse technology-knowledge networks, especially the aspects relating to management control. The management of technology knowledge in a network is characterised by a number of special features that are typical of this form of organization, on the basis of which, we point out the main obstacles and disadvantages that condition the achievement of efficiency of their management. We will analyse management in these networks in light of the experience of various European institutions that actively participate in networks for the development of technological projects. The principal mechanisms used for the control of management will be obtained from the empirical study. Finally, on the basis of the empirical verification, we will consider the development of certain general principles for control in order to achieve greater efficiency in the management of knowledge in these networks.  相似文献
