The imperfect hiding : some introductory concepts and preliminary issues on modularity

In this work we present a critical assessment of some problems and open questions on the debated notion of modularity. Modularity is greatly in fashion nowadays, being often proposed as the new approach to complex artefact production that enables to combine fast innovation pace, enhanced product variety and reduced need for co-ordination. In line with recent critical assessments of the managerial literature on modularity, we sustain that modularity is only one among several arrangements to cope with the complexity inherent in most high-technology artefact production, and by no means the best one. We first discuss relations between modularity and the broader (and much older within economics) notion of division of labour. Then we sustain that a modular approach to labour division aimed at eliminating technological interdependencies between components or phases of a complex production process may have, as a by-product, the creation of other types of interdependencies which may subsequently result in inefficiencies of various types. Hence, the choice of a modular design strategy implies the resolution of various tradeoffs. Depending on how such tradeoffs are solved, different organisational arrangements may be created to cope with ‘residual’ interdependencies. Hence, there is no need to postulate a perfect isomorphism, as some recent literature has proposed, between modularity at the product level and modularity at the organisational level

Defence firms facing liberalization: innovation and export in an agent-based model of the defence industry

The paper presents an agent-based simulation model of the defence industry. The model resembles some of the key characteristics of the European defence sector, and studies how firms in this market will respond to the challenges and opportunities provided by a higher degree of openness and liberalization in the future. The simulation analysis points out that European defence firms will progressively become more efficient, less dependent on public procurement and innovation policy support, and more prone to knowledge sharing and inter-firm collaborations. This firm-level dynamics will in the long-run lead to an increase in the industry’s export propensity and a less concentrated market.Defence industry; liberalization; EU; export; innovation; agent-based simulation model

Escaping Satiation in an Evolutionary Model of Structural Economic Dynamics

This paper presents the problem of satiation in relation to a model of evolutionary endogenous growth. The model represents an attempt to provide an evolutionary economic micro foundation to Pasinetti's scheme of the structural economic dynamics of a labour economy. Like this scheme the model deals with an economic system with a varying number of sectors, each of which is producing a consumption good. The goods are produced within consumer-producer firms which organise both production and consumption for their workers. Through innovative activities firms increase their productivity with respect to individual goods. The long-run consequence of this is that labour becomes available for the production of new consumption goods. If such goods are not provided to a sufficient degree, "technological unemployment" will emerge. If there is slow productivity development in the production of new goods, the overall rate of growth will slow down irrespectively of productivity growth in old sectors. Thus, to enhance long-term growth there is a need of "anticipatory R&D", i.e. R&D which produces designs for novel consumption goods and increases productivity in the production of these goods.Evolutionary modelling, endogenous growth and development, structural economic dynamics, satiation of demand, Robinson Crusoe.

The Publisher's final version can be found by following the DOI link.Purpose The experience of successful firms has proven that one of the most important ways to promote co-learning and create successful networked innovations is the proper application of inter-organizational knowledge mechanisms. This study aims to use a resource-action-performance framework to open the black box on the relationship between networking capability and innovation performance. The research population embraces companies in the Iranian automotive industry. Design/methodology/approach Due to the latent nature of the variables studied, the required data are collected through a web-based cross-sectional survey. First, the content validity of the measurement tool is evaluated by experts. Then, a pre-test is conducted to assess the reliability of the measurement tool. All data are gathered by the Iranian Vehicle Manufacturers Association (IVMA) and Iranian Auto Parts Manufacturers Association (IAPMA) samples. The power analysis method and G*Power software are used to determine the sample size. Moreover, SmartPLS 3 and IBM SPSS 25 software are used for data analysis of the conceptual model and relating hypotheses. Findings The results of this study indicated that the relationships between networking capability, inter-organizational knowledge mechanisms and inter-organizational learning result in a self-reinforcing loop, with a marked impact on firm innovation performance. Originality/value Since there is little understanding of the interdependencies of networking capability, inter-organizational knowledge mechanisms, co-learning and their effect on firm innovation performance, most previous research studies have focused on only one or two of the above-mentioned variables. Thus, their cumulative effect has not examined yet. Looking at inter-organizational relationships from a network perspective and knowledge-based view (KBV), and to consider the simultaneous effect of knowledge mechanisms and learning as intermediary actions alongside, to consider the performance effect of the capability-building process, are the main advantages of this research

The role of technology, organisation, and demand in growth and income distribution

The paper proposes a model that explains cross-country growth divergences over time for different aspects of structural change. The model formalises the links between production technology, firm organisation (functional composition of employment) on the supply side and the endogenous evolution of income distribution and consumption patterns on the demand side. Wage distribution is the main channel between the organisation of firms and consumption patterns, and firm selection is the main trigger of investment in new capital, productivity gains and cumulative growth. The model is able to reproduce empirical stylised facts on growth and income inequality associated with different stages of growth. We use VARs to estimate the causal relations between the three aspects of structural change. We then analyse the effect of the parameters that define the structure of an economy – and the way in which this unfolds through time – on growth and income distribution via numerical simulation. Product variety, differences in consumption preferences, organisational complexity and production technology determine whether the economy experiences a take-off or a stagnating growth, and the associated distribution of income

Jostling for Advantage or Not: Choosing Between Patent Portfolio Races and Ex Ante Licensing

Complex high technology industries are increasingly affected by patent thickets in which firms’ patents mutually block the use of important technologies. Firms facing patent thickets patent intensively to acquire bargaining chips and use licensing to ensure freedom to operate. Such licensing allows rivals to either avoid or resolve hold-up from blocking patents. R&D incentives depend on whether licensing takes place ex ante or ex post. We model the choice between ex ante licensing and entry into patent portfolio races leading to ex post licensing. It is shown that higher degrees of blocking lead firms to license ex post, while stronger product market competition leads firms to license ex ante. Empirical results support these theoretical predictions

Evolution of Supply Chain Collaboration: Implications for the Role of Knowledge

Increasingly, research across many disciplines has recognized the shortcomings of the traditional “integration prescription” for inter-organizational knowledge management. This research conducts several simulation experiments to study the effects of different rates of product change, different demand environments, and different economies of scale on the level of integration between firms at different levels in the supply chain. The underlying paradigm shifts from a static, steady state view to a dynamic, complex adaptive systems and knowledge-based view of supply chain networks. Several research propositions are presented that use the role of knowledge in the supply chain to provide predictive power for how supply chain collaborations or integration should evolve. Suggestions and implications are suggested for managerial and research purposes

R&D Subsidization effect and network centralization. Evidence from an agent-based micro-policy simulation

This paper presents an agent-based micro-policy simulation model assessing public R&D policy effect when R&D and non-R&D performing companies are located within a network. We set out by illustrating the behavioural structure and the computational logic of the proposed model; then, we provide a simulation experiment where the pattern of the total level of R&D activated by a fixed amount of public support is analysed as function of companies’ network topology. More specifically, the suggested simulation experiment shows that a larger “hubness” of the network is more likely accompanied with a decreasing median of the aggregated total R&D performance of the system. Since the aggregated firm idiosyncratic R&D (i.e., the part of total R&D independent of spillovers) is slightly increasing, we conclude that positive cross-firm spillover effects - in the presence of a given amount of support - have a sizeable impact within less centralized networks, where fewer hubs emerge. This may question the common wisdom suggesting that larger R&D externality effects should be more likely to arise when few central champions receive a support

Evolutionary models’ comparative analysis. Methodology proposition based on selected neo-schumpeterian models of industrial dynamics

A methodology of comparative analysis of evolutionary models is proposed. The main aim of this proposition is to identify to what extend different models can be called âevolutionary onesâ. Each model is analysed by searching for answers to following questions:  Is the model dynamical one?  Is it focused on far-from-equilibrium analysis?  What are a unit of evolution and a unit of selection?  Is diversity and heterogeneity of economic agents and their behaviour observed?  Is search for innovation based on a concept of hereditary information (knowledge)?  What kinds of innovation does the model describe?  Does selection process lead to diversified rate of growth and spontaneity of development?  How economic agents set prices?  What kind of products are described by the model?  Are decision making procedures and investment procedures present in the model? Outline of selected schumpeterian models is accompanied by identification of crucial evolutionary characteristics of each model and a short indication of phenomena explained by that model.Evolutionary economics, neo-schumpeterian models, simulation

An evolutionary model for the dynamics of vertical integration and network-based production

The concept of modularity has gained recently a growing attention in the management literature as a key to explain the contemporary trends of industrial dynamics. A stronger exploitation of external «networkbased» economies with respect to internal «bureaucracy-based» economies is one of the major consequences of the diffusion of flexible production systems and of modular architectures for products. To explain this connection, in this paper a model is presented which tries to explain the co-evolution of technology and organization as the outcome of a complex evolutionary process. In particular, through a set of exploratory agent-based simulations we try to show the existence of qualitatively different dynamic processes in coincidence of different phases and specific conditions of product and technology development, as well as the existence of a relationship between this dynamics and other competitive factors, determining a wide set of structurally different dynamical patterns in coincidence of different combinations of factors.modularity, modular networks
