antecedents and outcomes of modular production in the brazilian automobile industry a grounded theory approach our paper focuses on how foreign automobile manufacturers in brazil have implemented and benefited from strategic modularization based on our case studies and in depth interviews we developed a theoretical framework to examine the antecedents and outcomes of strategic modularization our theoretical framework suggests that strategic modularization may help improve a firm s positional advantage by reducing the cost of managing tacit knowledge in addition the adoption of strategic modularization influences the nature of relationships with major suppliers further blurring the boundaries of the firm

information on strikes and union settlements patterns of coverage in a newspaper of record the authors investigate whether the new york times coverage of strikes and non strike wage settlements in large bargaining units changed during the 1980s a time when a transformation of industrial relations is said to have taken place although the total number of new york times articles on such events declined during the 1980s the authors find that when appropriate control variables are included in the analysis the apparent drop in coverage disappears important variables determining the extent of news coverage were occurrence of a strike strike duration number of workers involved occurrence of federal intervention key industry status that is whether the affected industry was among those industries identified as exceptionally important for wage setting and proximity to new york city they speculate that the reduced number of articles may simply reflect a decreased incidence of strikes

meta paradigm change and the theory of the firm many seemingly unrelated debates on the theory of the firm are in fact part of a single deeper transformation of the social sciences as the foundational assumptions of 20th century social science have slowly been shown by science to be false new sub paradigms have emerged which cumulatively drop i theoretical assumptions about markets to explain firms ii epistemological assumptions about knowledge to explain diversity and iii metaphysical assumptions about causality to explain technical change debates occur across each of these levels

contracts as a barrier to entry it is shown that an incumbent seller who faces a threat of entry into his or her market will sign long term contracts that prevent the entry of some lower cost producers even though they do not preclude entry completely moreover when a seller possesses superior information about the likelihood of entry it is shown that the length of the contract may act as a signal of the true probability of entry

ten years of jibs at rutgers graduate school of management with the winter 1984 issue of jibs rutgers graduate school of management completes 2 terms or 10 years of publication of jibs this has been a challenging but rewarding experience for me and my staff at rutgers we take pride in the progress we have achieved after starting with meager and inadequate resources to make the journal of international business studies the outstanding refereed professional journal in the field this achievement was possible only through the dedicated efforts and cooperation of several score of individuals more than we can mention in this note including our small staff members of the editorial board section and other editors other reviewers many officers of the academy of international business authors who submitted manuscripts and various scholars who advised us on the editorial policies and thrust of the journal

assets and actions firm specific factors in the internationalization of u s internet firms by providing a nearly instant connection among parties at opposite corners of the world and enabling a variety of commercial exchanges the internet emerged as the technology expected to create a truly global market space internet firms faced the challenge of capitalizing on this development in this paper we examine what firm specific factors are associated with the propensity of pure u s based internet firms to enhance their international presence on the internet by developing country specific websites despite the assertion that all internet firms are born global our findings show that the pursuit of internationalization by internet firms is related to the levels of their intangible assets and strategic activity two types of intangible assets reputation and website traffic are positively related to the degree of internationalization so are the levels of competitive and cooperative activity and the interaction effects between reputation and competitive and cooperative activity these findings suggest that ideas from both resource based theory and research on competitive dynamics can contribute to understanding the internationalization of internet firms

strategic group formation and performance the case of the u s pharmaceutical industry 1963 1982 the focus of this paper is on three major questions 1 what is the theoretical rationale for the strategic group concept 2 does strategic group membership have performance implications and 3 are strategic groups and membership in strategic groups stable characteristics of industries a statistical procedure is proposed to longitudinally identify strategic groups the empirical setting is the u s pharmaceutical industry over the period 1963 82 while performance differences are found in terms of market share profitability differences between groups are not observed neither are differences found in terms of risk and risk adjusted performance these results are attributed to the existence of performance variation within each strategic group a dynamic model of competitive repositioning is proposed which helps integrate the findings from the study

strike activity worker militancy and productivity change in manufacturing 1961 1981 the author hypothesizes a two way causality between intracontractual strikes and productivity change in u s manufacturing on the one hand strikes during the term of a contract which are thought to reflect more broadly practiced shop floor militancy slow the pace of productivity growth and on the other hand periods of rapid productivity growth provoke increased intracontractual strike activity among other forms of shop floor protest the model is tested with quarterly data from 1961 through 1981 modified two stage least squares estimates support the hypothesis of two way causality a specific finding is that shop floor confrontation played a significant role in the slump in manufacturing productivity that began in the mid 1960s but not in the more precipitous productivity slowdown of the post 1973 years

industrial conflict and its implications for productivity growth the results of a factor analysis support the proposition that there are different dimensions to labor militance and that they behave differently over time further research is needed on the extent to which they are sensitive to changes in unemployment and the extent to which they can explain the behavior of productivity growth in the post war period if economic hard times enable employers to put labor on the defensive then ceteris paribus productivity growth may accelerate the critical implication for policymakers is that any effort to restore growth which does not take into account the distributive impact of increasing productivity will have only a limited success instead of simply exacerbating existing antagonisms between workers and companies policymakers need to address the source of the conflict the effect of increasing productivity on the quality of worklife 13 references 1 figure 2 tables

thorstein veblen and post darwinian economics thorstein veblen is noted for his view that economics should be an evolutionary science however although the term evolutionary has been adopted in general terms by subsequent institutional economists there has been remarkably little detailed exploration informed by biology of what veblen meant by an evolutionary science and the character of the post darwinian economics that he attempted to build this essay explores the reasons for veblen s attachment to darwinism informed by developments in biology itself and identifies some distinctive and enduring features of veblen s evolutionary theory copyright 1992 by oxford university press

patterns of technological competence accumulation a proposition for empirical measurement this article develops a typology that describes and measures different types of technological competence accumulation the notion of accumulation comprises not only the state but also the change in competence and hence it complies with the criticism of the static approaches to competence management the typology of competence accumulation enables a comparison of firm profiles that lead to identification of four groups of firm behavior across the telecommunications industry the relationship between the firm and the industry level is established on the condition that each firm s competence level depends on the firms mutual relationships with other firms in the same industry known as red queen evolution the four groups of firm behaviour are therefore not considered as groups of independent firms that are similar by coincidence but as patterns of behavior within the telecommunications industry which allows for a discussion of more general implications for management of technology copyright 2005 oxford university press

hiring molecules not atoms comobility and wages what role do social connections play in the labor market a vast influential literature has detailed the ways in which ties facilitate the flow of information about job opportunities to workers as well as endorsements or referrals of workers to firms we propose that this role is not constrained to an informational one alone rather relationships between workers can enable a collective job matching process that facilitates the transfer of shared human capital from one organization to another yet comobility has been studied only occasionally and among elite workers in particular industries this study delivers both fieldwork as well as large sample analysis among all nongovernmental workers in denmark finding a 5 5 wage premium for those who move jointly instead of independently both in the full sample as well as when applying strict matching or fixed effects for workers or firms co movers whose skills are related but not identical capture a higher premium and the wage gains associated with comob

an architectural framework for global talent management a unique characteristic of the multinational corporation is that it comprises a geographically dispersed and culturally differentiated workforce that embodies both firm specific and location specific human capital this article takes an architectural approach to describe how different types of human capital develop from the individual level to the unit level and then to the firm level in order to build a talent portfolio for the multinational corporation depending on the company s strategy multidomestic meganational transnational different configurations of the talent portfolio tend to be emphasized and integrated to achieve competitive advantage implications for theory and practice are discussed and a research agenda is introduced

cultural differences mne learning abilities and the effect of experience on subsidiary mortality in a dissimilar culture evidence from korean mnes in a departure from prior studies presuming a beneficial experience effect in foreign direct investment fdi the present paper examines the conditions under which fdi experience may actually harm subsequent subsidiaries we argue that multinational enterprises mnes may draw erroneous inferences and learn incorrectly from their early expansions when new to a dissimilar culture because their learning abilities are eroded by cultural differences we posit that the characteristics of an mne s international expansion including scope pace rhythm and entry mode moderate this negative experience effect by influencing the mne s learning ability in foreign cultures using a data set of fdis by south korean mnes between 1990 and 2006 we find a positive relationship between subsidiary mortality and experience when an mne has a low level of experience in a dissimilar culture this relationship is weaker if the mne s prior fdi has been dispersed across different cultures is stronger if it expanded internationally at a fast pace and becomes negative once the mne has accumulated a high level of experience in the host culture we conclude that when expanding into dissimilar cultures mnes must establish mechanisms to mitigate incorrect learning and reexamine the correctness of inferences drawn from past experience before applying them

fifty years of methodological trends in jibs why future ib research needs more triangulation we analyze methodological trends in empirical research in jibs from 1970 2019 our results point to the prevalence of the following patterns there has been an increase in the use of 1 large scale longitudinal cross national datasets 2 complex analytical techniques including the incorporation of multiple analytical techniques within the same study but 3 a decline in the diversity of methods in use we relate these trends to the underlying social technical and communicative conventions in the journal during the 50 year period the observed patterns are consistent with theory that posits scientific fields entrench a dominant paradigm over time resulting in a restricted set of methodological options being selected such restrictions jeopardize the quality of research because the study of any phenomenon requires the use of multiple methodological procedures to avoid the systematic biases errors omissions and limitations introduced by any single option therefore we propose the use of triangulation as a strategy for building methodological alternatives into research designs institutionalization of this principle in the field of international business has the potential to enhance both the rigor and scope of inquiry of future research

bounded rationality and tacit knowledge in the organizational capabilities approach an assessment and a re evaluation the famous three chapters in nelson and winter s an evolutionary theory of economic change 1982 that focus on firm routines and capabilities are often taken to be solidly founded on an assumption of bounded rationality i argue that in actuality bounded rationality plays a rather limited role in nelson and winter 1982 that the very different assumption of tacit knowledge is much more central and that the links between bounded rationality and routines capabilities are not clear i then argue that the absence in nelson and winter of a clear methodological individualist foundation for notions such as routines capabilities competencies etc has resulted in certain explanatory difficulties in the modern organizational capabilities approach that has taken so much inspiration from their work copyright 2003 oxford university press

veblen s evolutionary programme a promise unfulfilled this article examines in detail the way in which veblen attempted to give theoretical expression to the programme for an evolutionary economics that he outlined in methodological terms in his 1898 essay why is economics not an evolutionary science veblen s conception of darwinian methodological principles led him to attempt to develop a theory of institutional evolution that was purely causal in nature this theory was never satisfactorily developed by veblen at base his theory was one of new technology changing economic conditions and new economic conditions leading to new ways of thinking and to new institutions through a non intentional process of habituation those who attempted to follow veblen such as hoxie and mitchell found difficulties with the key aspects of this theory and both men came to abandon it institutionalism in the interwar period is devoid of attempts to develop veblen s theory and veblen s programme remained a promise unfulfilled

fdi spillovers over time in an emerging market the roles of entry tenure and barriers to imitation in this study we examine how foreign direct investment fdi spillovers to domestic firms in an emerging market occur over time from the organizational learning perspective we propose that as entry tenure of foreign firms in an industry increases domestic firms can learn from the foreign firms over time and improve their productivity we further build upon the competitor imitation argument to propose that this effect will be stronger when barriers to imitation faced by the domestic firms are lower based upon a comprehensive panel dataset on manufacturing firms in china in 1998 2007 our findings strongly support these arguments we find that entry tenure of foreign firms in an industry has a positive relationship with the productivity of individual domestic firms in the same industry albeit at a diminishing rate we also find that this positive relationship is stronger when the foreign firms have lower export intensity lower intangible asset intensity and have followed a more rhythmic i e less irregular entry pattern situations characterizing lower barriers to imitation

the source of optimality in action it is well known that the nature of the information set and the axioms of rational choice are critical in determining the type of ranking on which agents are held to act in economic theory this paper argues that the concept of the optimising agent is also sensitive to the conception of the relation between a ranking of options facing an agent and concrete action what is termed the realisation process three conceptions of the realisation process are examined which are seen to lead to three quite distinct views on the role of agency the enabling conditions under which the concept of the optimising agent may be legitimately applied and the resulting domain of application of optimisation

knowledge transfer capacity and its implications for the theory of the multinational corporation this study updates and extends research on foreign entry modes by examining the impacts of knowledge transfer capacity and knowledge tacitness research on international corporate expansion has long emphasized that deploying intangible knowledge based assets is required for successful international expansion more recently research from a knowledge based perspective has addressed the role of tacitness in constraining a firm s ability to transfer knowledge internationally we combine these perspectives to describe how knowledge tacitness affects the relative suitability of four archetypal entry modes exporting licensing establishing an alliance and wholly owned entry we then examine and develop conceptually a seldom studied firm characteristic knowledge transfer capacity we offer predictions that describe the combined effects of knowledge tacitness and transfer capacity on entry mode choice we distinguish between the transfer capacity of the organization that develops knowledge source transfer capacity and that of the organization that seeks to access that knowledge recipient transfer capacity the discussion addresses how our model generalizes to knowledge seeking strategies and to the study of ongoing multinational networks the study enriches and reconciles multiple theoretical perspectives on entry strategy it brings together the study of knowledge characteristics and firm heterogeneity in the theory of the multinational corporation and in international and strategic management more generally journal of international business studies 2003 34 356 373 doi 10 1057 palgrave jibs 8400037

the future of stakeholder management theory a temporal perspective we propose adding a temporal dimension to stakeholder management theory and assess the implications thereof for firm level competitive advantage we argue that a firm s competitive advantage fundamentally depends on its capacity for stakeholder management related transformational adaptation over time our new temporal stakeholder management approach builds upon insights from both the resource based view rbv in strategic management and institutional theory stakeholder agendas and their relative salience to the firm evolve over time a phenomenon well understood in the literature and requiring what we call level 1 adaptation however the dominant direction of stakeholder pressures can also change namely from supporting resource heterogeneity at the firm level to fostering industry homogeneity and vice versa when dominant stakeholder pressures shift from supporting heterogeneity towards stimulating homogeneity in industry the firm must engage in level 2 or transformational adaptation stakeholders typically provide valuable resources to the firm in an early stage without these resources which foster heterogeneity in line with rbv thinking the firm would not exist at a later stage stakeholders also contribute to inter firm homogeneity via isomorphism pressures in line with institutional theory thinking adding a temporal dimension to stakeholder management theory has far reaching implications for this theory s practical relevance to senior level management in business

location specificity and the transferability of downstream assets to foreign subsidiaries we investigate the effect of firm specific advantages being local in scope and the influence of subsequent location specific disadvantages on the choice of foreign entry mode and subsidiary performance to look into this issue we examine japanese fdi data from the wholesale and retail industries two sectors that have productive activity concentrated in downstream processes and location bound resources our theoretical and empirical analyses demonstrate that in situations where required capabilities must be developed through local experience and where location specific resources were subject to market failure acquisition and joint venture strategies were preferred greenfield entries were successful in industries that permitted the offsetting of location specific disadvantages with firm specific advantages from our results we draw implications for the entry mode literature and offer a perspective on the performance of the entry mode choice

interdependency competition and industry dynamics asystematic understanding of industry dynamics is critical to strategy research because individual firm performance dynamics both reflect and affect change at the industry level descriptive research on industry dynamics has identified a dominant pattern where prices fall output rises and the number of firms rises and then falls over time several models have been advanced to explain these patterns with a particular focus on explaining why a shakeout in the number of firms occurs in the most prominent models shakeout is generated by rising realized heterogeneity among firms that either is assumed to be unrecognized but determined ex ante or is generated by stochastic innovation outcomes coupled with convex adjustment costs and scale advantages in innovation and learning in this paper we develop an alternative model where heterogeneity develops among firms over time leading to a shakeout because firms must make choices about highly interdependent productive activities where the ideal combinations cannot be easily deduced or imitated by combining two established models a cournot model of competition with an nk model of interdependency in production activities we are able to advance an alternative explanation for the observed patterns of industry behavior including shakeout we show that variation in the potential for interdependency in activities among industries is able to explain varying levels of shakeout as well as differing patterns of entry and exit among industries notably the model generates several empirical predictions not apparent in past research and several that directly conflict with the results of prominent alternative models of industry dynamics specifically we show that when the potential for interdependency within an industry is low entry slows down and incumbent survival is all but assured whereas in industries where the potential for interdependencies is high shakeouts are severe and the rates of entry and exit remain high over longer time periods with decreasing survival rates for incumbents

no place like home relocation capabilities and firm survival in the german machine tool industry after world war ii we explore the extent to which organizational capabilities are location specific by studying the location choices and longevity of east german machine tool producers that relocated to west germany after world war ii relocating firms were similar in performance to experienced west german incumbents they outperformed new entrants without prewar industry experience this suggests they were able to build on capabilities acquired before the war even though relocating firms tended lo locate in industry agglomerations and in urbanized regions we find no evidence suggesting that firm performance benefited from agglomeration economies copyright 2011 the author 2010 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

corporate social responsibility product differentiation strategy and export performance this article argues that corporate social responsibility csr may contribute to product differentiation in export markets and thus improve export performance we test this argument by observing a period of decreasing export competitiveness in a leading emerging economy brazil using a large scale survey design with 252 questionnaires completed by medium and large sized brazilian exporters we used structural equations modelling to test our hypotheses the results suggest that csr product differentiation predicts export performance better than product quality differentiation and almost as well as product innovation differentiation multi group analysis further revealed that the positive and significant effect of csr product differentiation on export performance is likely to be contingent on the number and type developing vs developed of countries that are targeted our study contributes to the literature on csr and export performance by developing and empirically validating a model that explains under which conditions csr based product differentiation may lead to improved export performance

reputation and decision making under ambiguity a study of u s venture capital firms investments in the emerging clean energy sector this study examines the role of reputation on decision making under ambiguity drawing on social cognition and behavioral theories we propose that a firm s reputation exerts dual pressures on its decision making under ambiguity on the one hand a firm s reputation increases its aspirations for future performance and promotes its engagement in risky strategies to achieve them on the other hand preserving the already established reputation requires a firm to deliver consistent performance over time which promotes greater use of risk reduction strategies our analyses of the u s venture capital firms investments in the clean energy sector from 1990 to 2008 demonstrate that while reputable firms are more likely to invest in the emerging sector they also employ risk reduction strategies more extensively the sector s legitimation further influences these firms investment decisions both directly and through its interaction with firm reputation

an essay on the origins of entrepreneurial opportunity in this article we apply a process of logical inference to draw conclusions about the origins of entrepreneurial opportunity from existing conversations in the field of strategic management we equate the execution of a competitive strategy as described in the strategic management literature to the exploitation of an entrepreneurial opportunity as described in the entrepreneurship literature given this assumption we survey five extant theories of strategy in an attempt to categorize and describe the circumstances that define how and with what consequence entrepreneurial opportunity exploitation results in future opportunity given this review we characterize the outcomes of strategy execution as a function of the match between strategy and environment in an effort to extend and refine holcombe s holcombe randall 2003 review of austrian economics16 1 25 43 position that entrepreneurial opportunity is born of prior entrepreneurial action let your hook always be cast in the pool where you least expect it there will be a fish ovid a d 17

efficiency gains within firms under voluntary environmental initiatives this paper focuses on efficiency gains that voluntary environmental initiatives may achieve within the firm current debate concerning the extent and significance of inefficiencies within firms is critically important to the progress of energy and environmental policies several recent lines of inquiry in microeconomics help explain the persistence of inefficiencies within firms in addition two of the most prominent new approaches in the field of business strategy resource based strategy and the capabilities perspective focus on the heterogeneity among firms and the resulting pockets of inefficiency within firms they suggest at least three generic strategies for voluntary environmental initiatives challenging outdated organizational routines creating opportunities for differentiation or complementing firms resource investment trajectories these generic approaches suggest that there is considerable scope for further experimentation with voluntary environmental initiatives

the competence based approach veblenian ideas in the modern theory of the firm the author argues that a contemporary stronghold of a number of thorstein veblen s crucial ideas can be found in the emerging competence based approach to the firm e g penrose chandler winter for example the emphasis in this literature on firms as path dependent entities characterized by their heterogenous and group based knowledge bases can be linked with key themes in veblen s work thus the paper presents the competence based approach as a modern veblenian approach moreover the veblenian aspects of the competence based approach are also those aspects that most differentiate it from the other dominant economic approach to the firm the contractual approach e g alchian and demsetz williamson grossman and hart the aim of the paper is both to make this historical point and to present a contemporary body of theory that may with some justice be called veblenian copyright 1998 by oxford university press

don t rest on your laurels reputational change and young technology based ventures abstract we combine resource based theory and social cognition theory to investigate the factors both limiting and related to between period reputational change of young firms in a dynamic technology based industry an analysis of computer graphics chipmakers during the period 1992 2003 provides evidence that operational signals are related to reputational change specifically receiving a product award in the current period is associated with positive change and gaps in product announcements are associated with negative change we find little support for our hypothesis that the reputations of older firms are less likely to change

on the evolution of thorstein veblen s evolutionary economics this article addresses the origins of thorstein veblen s evolutionary economics as announced in his 1898 essay why is economics not an evolutionary science before 1897 and partly under the influence of c lloyd morgan veblen rejected biological reductionism veblen s 1897 endorsement of a critique of marxism by max lorenz shows that he found karl marx s account of human action too limiting by this time veblen had also rejected the idea of either the individual or society as exclusive foundations for social science instead he embraced an evolutionary framework of explanation along darwinian lines involving multiple levels of explanation and emergent properties copyright 1998 by oxford university press

the born global firm an entrepreneurial and capabilities perspective on early and rapid internationalization our 2004 journal of international business studies article innovation organizational capabilities and the born global firm provided a framework for the phenomenon of early and rapid internationalization among young entrepreneurial firms this work can be characterized as an integration of marketing entrepreneurial and capability based thinking around exporting positioned as the born global exporter the article also reported findings from a national study of start up firms that expanded abroad early in their evolution in the present commentary we reflect on the contributions of the 2004 article review the scholarship on the topic over the past decade and offer suggestions for future inquiry while the incidence of early internationalization by firms was a novel concept two decades ago today such firms are found in abundance in many countries yet many unresolved research questions remain including the crucial topic of what happens to born global firms as they grow and mature over time similarly the issue of why some firms internationalize early others late in their evolution and still others choose to remain local is a fundamental question for international business scholarship

an audit of technological innovation capabilities in chinese firms some empirical findings in beijing china abstract recent studies have advocated different technological innovation capabilities tics and discussed their impact on a firm s competitive performance this paper introduces a study framework of innovation audit and examines the relevance of seven tics to building and sustaining the competitiveness of chinese firms empirical data was acquired through a recent study of 213 chinese firms in beijing china regression analysis was employed to examine the correlation between tics and innovation rate sales growth and product competitiveness among these firms the findings verify that r d and resources allocation capabilities are the two most important tics a strong r d capability could safeguard innovation rate and product competitiveness in large and medium sized firms whereas a resources allocation capability would enhance the sales growth in small firms however the impact of learning and organising capabilities on a firm s innovation performance has yet to be investigated the findings of this paper suggest that chinese firms should consider a more balanced focus on their tics harmonising enhancement in order to maintain their sustainable development effectively plan and implement their innovation strategies as well as enhance their whole innovation capability chinese firms should closely relate their tics to the formulation of technology strategy and harmonisation of innovation and r d activities

a dynamic game of r and d patent protection and competitive behavior a theory of dynamic optimal resource allocation to r and d in an n firm industry is developed using differential games this technique represents a synthesis of the analytic methods previously applied to the problem static game theory and optimal control the use of particular functional forms allows the computation and detailed discussion of the nash equilibrium in investment rules this paper addresses the problem of resource allocation to research and development among the important issues that a firm engaging in r and d must evaluate are uncertainty regarding the feasibility and profitability of a particular innovation the possibility of a protracted development period the possibility that a rival firm may innovate first capturing either a patent or a significant share of the new market the possibility that a rival firm may imitate the innovation and appropriate some of the profits in the new market in what follows we will develop a theory of optimal resource allocation to research and development which incorporates the aspects of r and d enumerated above we will use a dynamic game theoretic analysis determining the nash equilibrium strategies for n identical firms the availability of perfect patent protection is shown to accelerate development of the innovation and the effect of increasing rivalry is addressed the impact of increasing rivalry on nash equilibrium investment in r and d depends upon the degree of appropriability of rewards if patent protection is perfect then increasing the number of nash rivals results in increased r and d effort however when imitation is rewarded the opposite may be true finally some notions of competitive and perfectly competitive equilibrium are examined in the context of the model developed below

random walks and sustained competitive advantage strategy is concerned with sustained interfirm profitability differences observations of such sustained differences are often attributed to unobserved systematic a priori differences in firm characteristics this paper shows that sustained interfirm profitability differences may be very likely even if there are no a priori differences among firms as a result of the phenomenon of long leads in random walks even a random resource accumulation process is likely to produce persistent resource heterogeneity and sustained interfirm profitability differences a cournot model in which costs follow a random walk shows that such a process could produce evidence of substantial persistence of profitability the results suggest that persistent profitability does not necessarily provide strong evidence for systematic a priori differences among firms nevertheless since the phenomenon of long leads is highly unrepresentative of intuitive notions of random sequences such evidence may still be persuasive
