sustainability in light of competitiveness abstract there is cause for concern that many current practices in the strategic use of advanced manufacturing technologies are unsustainable since they lead to increased resource consumption in the aggregate this article examines the ways the current generation of production technologies structure the formation and growth of product markets and explains why firms driven to stay competitive are adopting manufacturing strategies based on reducing the time it takes to develop and manufacture new products as experience in the use of advanced manufacturing technologies has accumulated distinctive patterns in market organization have emerged which in turn cause more firms to adopt these technologies in effect the markets and productions systems have co evolved faster product cycles presage new product variants and faster product obsolescence linked to intensified customers needs this interdependency of market needs and the strategic use of manufacturing technologies has significance for drafting sustainable consumption policy

transforming the energy sector the evolution of technological systems in renewable energy technology this paper analyses the development and diffusion of technologies that utilize renewable energy sources in germany sweden and the netherlands the analysis enlarges the life cycle model of industry evolution to one where the focus is on the formation and evolution of new technological systems particular focus is on explaining success and failures in shifting from a formative phase into one characterized by positive feedbacks a set of challenges is identified for policy makers attempting to influence the process of transforming the energy sector

technology shocks technological collaboration and innovation outcomes in the early to mid 1990s technology alliances suddenly surged to unprecedented levels roughly 300 growth per year from 1990 to 1995 and then declined just as precipitously this massive increase in alliance activity caused the crystallization of a giant component in the global technology network that connected a large portion of the world s firms government labs universities and other organizations however when alliance activity declined the component disintegrated what caused this spike in alliance activity and did this large but transient change in collaboration activity leave any enduring effect the data here suggest that a major technology shock may have provoked this alliance surge a technology shock may simultaneously unleash significant innovation opportunities while creating great uncertainty in the economic environment though it is well known that firms often use alliances both to respond to uncertainty and facilitate innovation little is known about how technology shocks affect the collaboration behavior of firms and how these two factors separately influence innovation outcomes i integrate an inductive study of collaboration activity and a technology shock with existing research on economics alliances and networks to build a set of arguments about how technology shocks will influence alliance behavior how changes in alliance behavior will influence the global technology collaboration network and about how each of these changes is likely to influence the innovative outcomes of firms i then explore the separate and joint effects of the technology shock and collaboration activity on innovation using a large sample panel study of patenting by north american firms

a prelaunch diffusion model for evaluating market defense strategies this paper describes the development and application of a marketing model to help set an incumbent s defensive marketing strategy prior to a new competitor s launch the management problem addressed is to assess the market share impact of a new entrant in the residential australian long distance telephone call market and determine the factors that would influence its dynamics and ultimate market appeal the paper uses probability flow models to provide a framework to generate forecasts and assess the determinants of share loss we develop models at two levels of complexity to give both simple robust forecasts and more detailed diagnostic analysis of the effect of marketing actions the models are calibrated prior to the new entrant s launch enabling preemptive marketing strategies to be put in place by the defending company the equilibrium level of consideration of the new entrant was driven by respondents strength of relationship with the defender and inertia while trial was more price based continued use of the defender depends on both service factors and price the rate at which share loss eventuates is negatively related to the defender s perceived responsiveness saving money being the only reason to switch and risk aversion prelaunch model forecasts validated six months after launch using both aggregate monthly sales data and detailed tracking surveys are shown to closely follow the actual evolution of the market the paper provides a closed form multistate model of the new entrant s diffusion a methodology for the prelaunch calibration of dynamic models in practice and insights into defensive strategies for existing companies facing new entrants

competitive strategies for late entry into a market with a dominant brand this paper considers optimal positioning advertising and pricing strategies for a firm contemplating entry in a market dominated by an entrenched competitor drawing on behavioral research on consumer preference formation we develop an individual level model that reflects differing consumer responses to similar products offered by the dominant brand and later entrants an effect we term asymmetric preferences from the resulting aggregate market response model we derive several competitive implications notably 1 that preference asymmetry can make a differentiated late entry strategy optimal even if preferences would appear to dictate otherwise and 2 that me too strategies are not equilibrium late entry strategies more generally our analysis suggests that preference asymmetry can contribute to the persistent competitive advantage of dominant brands

explaining the attacker s advantage technological paradigms organizational dynamics and the value network abstract understanding when entrants might have an advantage over an industry s incumbent firms in developing and adopting new technologies is a question which several scholars have explained in terms of technological capabilities or organizational dynamics this paper proposes that the value network the context within which a firm competes and solves customers problems is an important factor affecting whether incumbent or entrant firms will most successfully innovate in a study of technology development in the disk drive industry the authors found that incumbents led the industry in developing and adopting new technologies of every sort identified by earlier scholars at component and architectural levels competency enhancing and competency destroying incremental and radical as long as the technology addressed customers needs within the value network in which the incumbents competed entrants led in developing and adopting technologies which addressed user needs in different emerging value networks it is in these innovations which disrupted established trajectories of technological progress in established markets that attackers proved to have an advantage the rate of improvement in product performance which technologists provide may exceed the rate of improvement demanded in established markets this mismatch between trajectories enables firms entering emerging value networks subsequently to attack the industry s established markets as well

speciation through entrepreneurial spin off the acorn arm story abstract can the concept of speciation explain evidence on how technologies branch and advance can evidence on innovation through spin off usefully inform the concept of speciation these questions are addressed through a case study of detailed processes enabling the shift of technology to new domains of application an innovative it firm developed its own semiconductor technology to remedy supplier deficiencies but it required a joint venture with a completely new business model to adapt and move the technology into new market domains we propose the concept of techno organizational speciation to delineate this phenomenon competing perspectives on speciation compatibility niche and lineage approaches are found to illuminate the evidence while complementarities between these conceptual dimensions are revealed by the case causal processes uncovered include the following 1 techno organizational speciation through spin off may be needed to launch a dominant technical standard compatible with multiple applications 2 this can be achieved through niche creation from which develops a new business ecosystem 3 inherited knowledge together with organizationally based learning foster the branching and renewal of technological lineages

defensive marketing strategies this paper analyzes how a firm should adjust its marketing expenditures and its price to defend its position in an existing market from attack by a competitive new product our focus is to provide usable managerial recommendations on the strategy of response in particular we show that if products can be represented by their position in a multiattribute space consumers are heterogeneous and maximize utility and awareness advertising and distribution can be summarized by response functions then for the profit maximizing firm it is optimal to decrease awareness advertising it is optimal to decrease the distribution budget unless the new product can be kept out of the market a price increase may be optimal and even under the optimal strategy profits decrease as a result of the competitive new product furthermore if the consumer tastes are uniformly distributed across the spectrum a price decrease increases defensive profits it is optimal at the margin to improve product quality in the direction of the defending product s strength and it is optimal at the margin to reposition by advertising in the same direction in addition we provide practical procedures to estimate 1 the distribution of consumer tastes and 2 the position of the new product in perceptual space from sales data and knowledge of the percent of consumers who are aware of the new product and find it available competitive diagnostics such as the angle of attack are introduced to help the defending manager this article was originally published in marketing science volume 2 issue 4 pages 319 360 in 1983

towards a dynamic schumpeterian welfare economics knowledge plays an increasingly important role in shaping the dynamics of an economy a static paretian welfare economics is therefore inadequate and needs to be supplemented by a dynamic schumpeterian welfare theory a dynamic welfare economics acknowledges the role of knowledge and communication as knowledge develops cumulatively in a social environment knowledge may not be readily diffused or exchanged different costs of communication need to be considered each affecting the creation of new knowledge recent developments in intellectual property right ipr law are evaluated to determine the extent to which they affect communication costs and thus future economic welfare

an equilibrium analysis of defensive response to entry using a coupled response function model we determine the optimal response to competitive entry in a market characterized by a market share attraction model the response of an incumbent is limited to changes in prices advertising and distribution expenditures brand positions are assumed to be fixed we also assume that the entrant s position is chosen exogenously and that the sales potential of the market is constant after proving the existence of a unique nash equilibrium we show that the optimal response depends on the relative market share of the incumbents the response by nondominant brands with market shares less than 50 mirrors the prediction by decoupled response function models reduce price advertising and distribution spending for the dominant brand having a market share of 50 the response is to reduce price and increase marketing spending this finding explains previous empirical results that could not be addressed by the decoupled models

can guest workers solve japan s fiscal problems the labor force in japan is projected to fall from 64 million in 2014 to 20 million in 2100 signaling unprecedented tax transfer adjustments to achieve fiscal sustainability in this paper we develop a quantitative overlapping generations model to measure the impact of guest worker programs in japan against a baseline general equilibrium transition in which the consumption tax adjusts to achieve fiscal sustainability we compute alternative transitions with guest worker programs depending on the size and skill distribution of guest workers these programs may mitigate japan s fiscal imbalance problem with a relatively manageable increase in the consumption tax jel e2 e6 h5 j11 j15

light emitting diodes and the lighting revolution the emergence of a solid state lighting industry emergence of new industries from evolving technologies is critical to the global economy yet has been relatively understudied due to the paucity of available data this study draws lessons on industry emergence by analyzing how a solid state lighting ssl industry grew out of light emitting diode led technologies that evolved for half a century with participation by tens of thousands of researchers in universities national laboratories and firms using data on publications patents and firms combined with business history we trace the evolution of ssl through a succession of market niches at times a few researchers with unorthodox research approaches made breakthroughs that greatly advanced particular technology trajectories and pushed led research in unexpected directions a succession of led market niches advanced the technology and provided profits to incentivize continuing research while reducing cost and improving efficacy of leds innovating firms developed a thicket of patents and captured substantial profit but were embroiled in extensive litigation that was ultimately resolved through cross licensing a major new generation of lighting products is now disrupting the traditional lighting industry although the leading incumbent lighting firms all invested early and heavily in ssl the industry s future leadership is uncertain

predicting the path of technological innovation saw vs moore bass gompertz and kryder competition is intense among rival technologies and success depends on predicting their future trajectory of performance to resolve this challenge managers often follow popular heuristics generalizations or laws such as moore s law we propose a model step and wait saw for predicting the path of technological innovation and we compare its performance against eight models for 25 technologies and 804 technologies years across six markets the estimates of the model provide four important results first moore s law and kryder s law do not generalize across markets neither holds for all technologies even in a single market second saw produces superior predictions over traditional methods such as the bass model or gompertz law and can form predictions for a completely new technology by incorporating information from other categories on time varying covariates third analysis of the model parameters suggests that i recent technologies improve at a faster rate than old technologies ii as the number of competitors increases performance improves in smaller steps and longer waits iii later entrants and technologies that have a number of prior steps tend to have smaller steps and shorter waits but iv technologies with a long average wait time continue to have large steps fourth technologies cluster in their performance by market

comments on competitive responsiveness marketing science features many and diverse articles that analyze competitive responsiveness although recent marketing science editorials e g shugan 2002 suggest that competitive responsiveness is only a part of a comprehensive competitive marketing strategy it remains a vital part for that reason and many others marketing science is particularly proud of this special issue edited by david j reibstein and dick r wittink before introducing and vigorously applauding both the editors and authors of this excellent special issue we emphasize that competitive responsiveness raises numerous issues including whether one can forecast outcomes of new policies based on past observations made under old policies i e the lucas critique and decisions regarding which variables should be considered endogenous shugan 2004 i e determined within the model perhaps normative models are inherently perishable evolution in market structure requires modifications over time also although complete consistency within the world of the model is aesthetically pleasing imposing industry specific exogenous constraints that might appear unrelated to the modeling assumptions is sometimes necessary

towards alternative trajectories reconfigurations in the dutch electricity regime abstract in the early 2000s dutch electricity companies are increasingly investing in technologies that enable them to replace coal with biomass replacing large amounts of coal up to 40 requires the companies to invest in technological trajectories alternative to the ones they have supported over the past decades this paper aims to understand why these incumbent firms in the dutch electricity regime are developing alternatives the second aim of the paper is to provide a way for assessing the potential of innovations the paper does so by bringing together insights from literature on socio technical regimes and insights from literature on technological and market niches strategic niche management the main conclusion is that both niche processes at the level of experimenting with alternatives and changes in the incumbent regime are necessary for understanding the innovation journey of a new technology a two by two matrix is developed that can be used for both analysis and governance purposes

who invests in renewable electricity production empirical evidence and suggestions for further research transforming energy systems to fulfill the needs of a low carbon economy requires large investments in renewable electricity production res e recent literature underlines the need to take a closer look at the composition of the res e investor group in order to understand the motives and investment processes of different types of investors however existing energy policies generally consider res e investments made on a regional or national level and target investors who evaluate their res e investments according to least cost high profit criteria we present empirical evidence to show that res e investments are made by a heterogeneous group of investors that a variety of investors exist and that their formation varies among the different types of renewable sources this has direct implications for our understanding of the investment process in res e and for the study of motives and driving forces of res e investors we introduce a multi dimensional framework for analyzing differences between categories of investors which not only considers to the standard economic dimension which is predominant in the contemporary energy literature but also considers the entrepreneurship innovation adoption and institutional dimensions the framework emphasizes the influence of four main investor related factors on the investment process which should be studied in future research motives background resources and personal characteristics

determining the appropriate depth and breadth of a firm s product portfolio abstract some firms have broad product lines others have lean product lines to determine the appropriate number of entries in a specific firm s product line the author develops a model that balances the benefits of increased revenue from a broad product line against production and engineering costs two innovations were central in the development of the model 1 redefining how products are scored on various product attributes so that attribute scores vary normally across the population of products and 2 redefining how the number of entries in a product portfolio is calculated in order to discount the significance of entries that are highly similar to existing products the author also introduces the notion of a centroid time to more easily adjust sales and total development costs for product life cycle and investment life cycle effects these redefinitions enable a firm s profit to be modeled as a simple function of its effective number of product entries the effective number of competitors entrie

anniversary article the strategy field from the perspective of management science divergent strands and possible integration we reflect on the evolution of the strategy field as seen through the window ofmanagement science reflecting the diverse disciplinary roots of strategy research we identify a broad ranging body of work that varies with respect to the assumptions made regarding individual rationality and the level of analysis at which the research is carried out we argue that recent developments begin to delineate a potentially unifying conceptual framework for treating the field s defining questions the conceptual apparatus of evolutionary economics we conclude by laying out important challenges for evolutionary economics if it is to serve as a foundation for both the positive and the normative research agendas of the strategy field

the dynamics of innovative activity and competitive advantage the case of australian retail banking 1981 to 1995 this study examines the adoption of new products and processes in the australian retail banking industry over the 1981 to 1995 period our analysis demonstrates that the vast majority of observed innovative activity was based on ideas sourced from outside the focal firm and that innovations diffused very quickly across competing banks as such there were no periods during which any bank had proprietary possession of a major product or process innovation we therefore ask how the banks innovative activity could affect their relative financial performance positions we answer this question by developing a set of hypotheses that relate specific features of their histories of innovative activity to their current financial performance these hypotheses are tested using a detailed data set describing 1 297 modifications made to products and services distribution technologies and back office processes within a sample of australian retail banks over the sample period our results provide support for the general position that establishing an attractive competitive position depends on the specific history of a firm s innovative activity banks that undertook more innovative activity that were more consistent in that activity and whose composition of activity was somewhat differentiated from the industry norm tended to display superior financial performance rather than looking solely for internally generated inimitable innovations to deliver competitive advantage these results suggest that active and consistent innovative activity that is somewhat differentiated from competitors can also deliver superior financial performance

factor markets actors and affordances in this article we challenge the notion of the efficiency of factor markets and provide an alternative we specifically identify both the environment and actor related origins of heterogeneity in markets we first discuss how environments have an exaptive nature where new uses and possibilities emerge continuously and are poised for the taking we then highlight how actor perceptions result in heterogeneous outcomes and how the identification of novel affordances new uses or functions for factors is a central origin of heterogeneity we also discuss the existence of actor and environment related pressures toward homogeneity and seeming market efficiency in conclusion we highlight the implications of our arguments for the strategy and innovation debate and for our understanding of the nature of markets and economic activity

the effect of immigrant peers in vocational schools abstract this paper provides new evidence on how the presence of immigrant peers in the classroom affects native student achievement the analysis is based on longitudinal administrative data on two cohorts of vocational training students in italy s largest region vocational training institutions provide the ideal setting for studying these effects because they attract not only disproportionately high shares of immigrants but also the lowest ability native students we adopt a value added model and exploit within school variation both within and across cohorts for identification our results show small negative average effects on maths test scores that are larger for low ability native students strongly non linear and only observable in classes with a high top 20 immigrant concentration these outcomes are driven by classes with a high average linguistic distance between immigrants and natives with no apparent additional role played by ethnic diversity

commentary defensive marketing strategies for every new product and service entrant there are usually many incumbents who must defend their positions in the market hence defensive strategy is as least as critical as new product strategy our 1983 article argued that defensive strategy critically depends on the distribution of buyer preferences and the position of the new entrant relative to the position of the incumbent in a multidimensional attribute space since the appearance of our 1983 article in marketing science research in defensive strategy has progressed in both prescriptive and descriptive directions subsequent research on defensive strategy has also addressed empirical methodological theoretical and substantive issues today defensive strategy is more important than ever with shorter new product life cycles persistent service innovation remarkable technological change global competition and the invention of new channels of distributions

response to competitive entry a rationale for delayed defensive reaction empirical studies examining responses to new product entries come to the puzzling conclusion that in general an incumbent reacts to a new entrant after a significant delay even easy to implement price cuts are observed after significant lag following entry these findings seem to contradict the existing literature that either implicitly assumes or strongly advocates immediate defensive responses to limit competitive encroachment when a competing firm enters the market consumers may be uncertain about the entering firm s product quality the incumbent firm through rigorous tests may fully know the entrant s quality suppose the incumbent aggressively lowers price this may cause the consumers to wonder if indeed the entrant s quality is high in other words an incumbent s reaction may cause the consumers to make inferences about the entrant s quality such strategic implications of the incumbent s reactions have to be carefully analyzed before determining the optimal response by the incumbent in this paper we propose a conceptual framework for understanding differences in the magnitude and timing of incumbents responses to competitive entries we consider a model in which a monopolist incumbent firm faces competitive entry the incumbent firm knows the true quality of the entrant with certainty although consumers are aware of the incumbent s product quality through their prior experience they are initially uncertain of the entrant s product quality in such a situation a high quality entrant has the incentive to signal her true quality through her strategic price choice however the uncertainty about the entrant s quality is favorable to the incumbent in the sense that consumers believe with a high probability that the entrant s quality is low as a result the strategic incentives facing the incumbent and the entrant oppose each other while the entrant wants to signal her high quality the incumbent wants to prevent her from doing so we demonstrate that one way the incumbent can prevent the quality signaling is to select a higher than his optimal competitive duopoly price in other words the incumbent can prevent or jam the entrant s quality signaling by choosing a price higher than his optimal competitive price when consumers are fully informed about the entrant s true quality though the signal jamming price is lower than the monopoly price the price is substantially higher than the competitive price this marginal reduction in the incumbent s price from the pre entry monopolistic price represents a muted or lack of response by the incumbent to the competitive entry however once the entrant s quality gets revealed in subsequent periods through consumer usage and word of mouth the entrant has no incentive to engage in quality signaling and the incumbent has no incentive to jam it therefore the market reverts to the complete information competitive prices and the incumbent lowers his price considerably this temporal pattern of muted price reduction in the first period followed by a sharp price reduction in the second period corresponds to a delayed defensive reaction in our model although the empirical studies suggest that the delayed reaction may arise due to factors such as managerial inertia or indecision we demonstrate that such a behavior is indeed an optimal strategy for a profit maximizing firm thus our model reconciles empirical results with the equilibrium outcome of a strategic analytical framework furthermore in an experimental setting we test the predictive power of our framework and establish that consumers indeed form conjectures about the entrant s quality based on the incumbent s reactions in the first experimental study we find strong support for the notion that the incumbent s price reaction may indicate entrant s quality in a follow up study we observe that whenever the incumbent lowers prices respondents judge the quality of the entrant to be higher as compared to the case when prices are the same or increased the managerial implication of this paper is that well established incumbent firms should be cautious in the implementation of their defensive responses to product introductions of uncertain quality by competitors of particular concern are situations where the reactions are easily observable by consumers a strong reaction may suggest that the incumbent takes the competitive threat seriously leading consumers to believe in the quality of the competitor s product

competitive reactions to advertising and promotion attacks how do competitors react to each other s price promotion and advertising attacks what are the reasons for the observed reaction behavior we answer these questions by performing a large scale empirical study on the short run and long run reactions to promotion and advertising shocks in over 400 consumer product categories over a four year time span our results clearly show that the most predominant form of competitive response is passive in nature when a reaction does occur it is usually retaliatory in the same instrument i e promotion attacks are countered with promotions and advertising attacks are countered with advertising there are very few long run consequences of any type of reaction behavior by linking reaction behavior to both cross and own effectiveness we further demonstrate that passive behavior is often a sound strategy while firms that do opt to retaliate often use ineffective instruments resulting in spoiled arms accommodating behavior is observed in only a minority of cases and often results in a missed sales opportunity when promotional support is reduced the ultimate impact of most promotion and advertising campaigns depends primarily on the nature of consumer response not the vigilance of competitors

immigration and public finances in oecd countries abstract this paper shows that the macroeconomic and fiscal consequences of international migration are positive for oecd countries and suggests that international migration produces a demographic dividend by increasing the share of the workforce within the population the estimation of a structural vector autoregressive model on a panel of 19 oecd countries over the period 1980 2015 reveals that a migration shock increases gdp per capita through a positive effect on both the ratio of working age to total population and the employment rate international migration also improves the fiscal balance by reducing the per capita transfers paid by the government and per capita old age public spending to rationalize these findings an original theoretical framework is developed this framework highlights the roles of both the demographic structure and intergenerational public transfers and shows that migration is beneficial to host economies characterized by aging populations and large public sectors

competing technologies and market dominance standard battles in the local area networking industry the rise of fast ethernet as the dominant standard for high speed connection in the local area networking industry is chosen to study the interaction between increasing returns to adoption and technical change in innovation diffusion contrary to most of the empirical papers on diffusion with increasing returns which study competition between an entrenched technology and a new competitor the focus is on the case in which several and different versions of a new technology are competing at the same time for market dominance within this context this article studies under which conditions an early technology may fail to capitalise on its initial time advantage and a new version without a clear early lead may become dominant in particular we will consider a case in which the initial time advantage is made ineffective by consistently adverse technological expectations then we analyse how the arrival on the market of different categories of buyers sensitive to specific applications further contribute to weaken the early leader and strengthen a competing version this is more likely to occur when buyers are highly familiar with the characteristics of that specific version copyright 2008 oxford university press

intergenerational hybrids spillbacks spillforwards and adapting to technology discontinuities during technological discontinuities incumbents frequently develop hybrids of competing technical generations although some prior work implies that such intergenerational hybrids may be the result of organizational dysfunction we propose that in some cases hybrids may be sophisticated learning tools that shape organizational adaptation to a technological discontinuity in this paper we suggest two mechanisms through which intergenerational hybrids may affect organizational adaptation spillbacks and spillforwards in an empirical test among the population of automobile carburetor manufacturers during a technological discontinuity we observe that organizations developing intergenerational hybrids capture spillback benefits knowledge spillovers from an emerging technology generation to the current generation furthermore we find that these same organizations also capture spillforwards spillover benefits from developing higher performing intergenerational hybrids that improve their product performance in the future technology generation these results suggest that intergenerational hybrids may be stepping stones for organizations to learn about and adapt to technology discontinuities

defensive marketing strategies an equilibrium analysis based on decoupled response function models the entry of a new product attacker into a competitive market is likely to provoke responses from some or all of the existing products defenders this paper investigates the development of optimal defensive strategies based on an understanding of the possible reactions of all the defenders to an optimal attack following lane lane w j 1980 product differentiation in a market with endogenous sequential entry bell j econom 11 1 spring 237 260 we assume that n products each enter sequentially with perfect foresight on subsequent entry then based on new technology an unanticipated attacker enters the n defenders respond in price but not position according to lane s model once this equilibrium is obtained advertising and distribution response functions scale sales we show that under these decoupled response function models of advertising and distribution uniformly distributed tastes and nonincreasing market size the optimal defense for all existing brands is to decrease their respecti

evolutionary chimeras a woesian perspective of radical innovation this article proposes a novel perspective of technological change based on the woesian model of cell evolution to study technological change and in particular the origins of radical innovation the model identifies horizontal gene transfer hgt as a critical force that drives evolution and complements the darwinian theory of vertical inheritance building on this model we highlight the key role of the horizontal transfer of functional modules in generating radical innovation as well as strengthening the analogy between biological and technological evolution we use the turbojet revolution to illustrate the main features of the model and elucidate the conditions under which horizontal transfer is a crucial evolutionary force leading to radical innovation we then elaborate on the implications of the model for how firms should search for radical innovation as well as emphasize the importance of a firm s replicative integrative capability that is the ability to replicate with modifications existing functional modules and integrate them into a novel architecture in shaping the generation of radical innovation

prescribing product upgrades prices and production levels over time in a stochastic environment abstract competitive pressures cause the price of high technology products to erode over time the purpose of this paper is to describe a decision support tool to maximize profit by prescribing three related decisions product upgrading pricing and production levels a stochastic dynamic programming dp model prescribes when to upgrade a product and what new technologies to incorporate to maintain product competitiveness and profit margins it deals with the two major sources of risk demand and the lead time required to complete an upgrade the objective of the dp model is to maximize expected profit over a given planning horizon decision variables prescribe which alternative upgrades to implement and when pricing and production levels benchmarking computational tests are described along with an example demonstrating model application managers can use this dp model to coordinate decisions related to product upgrading pricing and operations management to better meet business objectives

technological pre adaptation speciation and emergence of new technologies how corning invented and developed fiber optics this article investigates how established firms innovate and even initiate new technological trajectories we build on and expand the notion of technological speciation to describe how a new technology emerges when a firm leverages its technological knowledge into a new application domain current research on technological speciation does not investigate how firms accumulate the technological knowledge which they eventually redeploy into different domains nor does it clarify the precise role of luck historical accidents and foresight strategy in shaping the overall process this requires a finer grained investigation of the microprocesses and evolutionary forces underlying the dynamics of technological speciation to this end we use a longitudinal case study of corning s invention and development of fiber optics technology we focus less on testing theory and more on describing a phenomenon to generate new theoretical insight

analyzing the fiscal impact of u s immigration this paper reconsiders the fiscal impact of immigrants over time in the us by using the technique of generational accounting introduced by auerbach et al generational accounting considers not only the net contribution of immigrants to fiscal balance but also the size of this impact in relation to the overall balance it further compares changes in immigration policy to other policies from the analysis three conclusions were formulated 1 whether immigration contributes to or helps alleviate fiscal stress depends on the future generations if the entire fiscal imbalance currently estimated for the us is placed on future generations then the presence of new immigrants reduces the burden of the natives 2 fiscal gain from immigration is reduced when a policy of fiscal responsibility is followed the gain is dependent on the extent to which government purchases rise with the immigrant population 3 the impact of immigration on fiscal balance is extremely small in relation to the size of the overall imbalance itself thus immigration should not be perceived as a major source of the existing imbalance or as a potential solution to it

the slow pace of rapid technological change gradualism and punctuation in technological change discussions of technological change have offered sharply contrasting perspectives of technological change as gradual or incremental and the image of technological change as being rapid even discontinuous these alternative perspectives are bridged using the punctuated equilibrium framework of evolutionary biology using this framework it is argued that the critical event is not a transformation of the technology but speciation the application of existing technology to a new domain of application as a result of the distinct selection criteria and the degree of resource abundance in the new domain a new technological form may emerge the new technological form may be able to penetrate other niches and in particular may precipitate a process of creative destruction and out compete prior technologies this framework is applied to an historical study of wireless communication from the early experimental efforts of hertz to the modern development of wireless telephony

the effect of immigration on public finances the impact of immigration on the public finances is an important influence on public opinion this study aims to provide a thorough conceptual survey pointing out the complexities of a full understanding and the relevance of indirect effects and covering both static perspectives and longer run dynamic issues it considers simple accounting approaches which are relatively neglectful of behavioural responses but also tries to bring out the complexities in the nature of the relationship between immigration and the public exchequer that come with more sophisticated modelling of its economic effects

when shakeout doesn t occur the evolution of the turboprop engine industry abstract a careful case study of the history of the turboprop engine industry 1948 1997 is offered as an example of non shakeout pattern the persistence of high concentration is not associated with the exit of smaller manufacturers but instead a stable coexistence of generalist and specialist strategies emerges in sharp contrast to the pattern observed in the otherwise similar jet engine industry this paper identifies the relevant variables of a more general theory of industry life cycle by taking into account the lack of creation of significant increasing returns in r d manufacturing or marketing all of which are commonly found in industries that produce systemic products

division of labor organizational coordination and market mechanisms in collective problem solving abstract this paper builds upon a view of economic organizations as problem solving arrangements and presents a simple model of adaptive problem solving driven by trial and error learning and collective selection institutional structures and in particular their degree of decentralization determine which solutions are tried out and undergo selection it is shown that if the design problem at hand is complex in terms of interdependencies between the elements of the system then a decentralized institutional structure is unlikely ever to generate optimal solutions and therefore no selection process can ever select them we also show that nearly decomposable structures have in general a selective advantage in terms of speed in reaching good locally optimal solutions

the system dynamics of collective knowledge from gradualism and saltationism to punctuated change abstract the economics of localized technological change provides an original framework to model the dynamics of technological innovation as the result of the interaction between the inducement to change the technology generated by the mismatch between plans and expectations and the characteristics of the system the interplay between networking costs and knowledge supermodularity can explain both punctuated and gradual change small variations in the parameters can generate either gradual or discontinuous changes punctuated technological change is likely to take place when the interplay between positive and negative knowledge externalities leads to the creation of commons of collective knowledge and hence new technological systems

socio technical inertia understanding the barriers to electric vehicles it is widely accepted that electrification of the transport sector is one of several technological trajectories that could redress some of the environmental issues associated with the growth in travel demand including climate change and oil demand at a global scale and air quality and noise pollution at the urban scale electric vehicles have been considered a promising technology at repeated intervals over the last century but this promise has not been realised this paper is a contribution to understanding the key tools and strategies that might enable the successful introduction of new technologies and innovations by exploring the key barriers to electric vehicles encountered in two countries uk and germany where the automobile industry has been historically significant the study evaluates stakeholders opinions on relevant regulation infrastructure investment r d incentives and consumer incentives the key findings of the research are that the introduction and penetration of evs is confronted by several barriers that inhibit a larger market penetration under current conditions which in turn casts doubt on the assumptions of strategic niche management and transitions theory

estimating the impact of immigrants on the host country social security system when return migration is an endogenous choice in this paper i examine the impact of immigrants on the social security system in germany when return migration is an endogenous choice for this purpose i develop a dynamic stochastic model of joint return migration and saving decisions that accounts for uncertainty in future employment and income and estimate this model using a longitudinal dataset on immigrants from five different source countries i find that immigrants make positive net contributions to both the pension and unemployment insurance systems in germany regardless of their country of origin and age at entry moreover the magnitudes of the net contributions are remarkable for certain groups return migration plays a critical role in generating these positive net contributions in a counterfactual i examine how much exogenous modeling of the return decision which has been the practice of the literature so far changes immigrants net contributions such a restriction causes a serious misestimation of net contributions i also examine the impact of a counterfactual policy experiment in which financial bonuses are provided conditional on return to certain unemployed immigrants such a policy turns out to be ineffective in a number of dimensions
