understanding innovation an analysis of persistence for spanish manufacturing firms abstract this study focuses on the persistence of innovation in a panel of spanish manufacturing firms for the period 1990 2008 in particular we analyse whether persistence in firms innovation activities over time is the result of previous experience the dynamic capabilities of the firm or industry market related characteristics we find that r d input and innovation output are highly persistent at the firm level after controlling for unobserved heterogeneity and initial conditions and by using a dynamic random effects probit we conclude that there are similar determinants of persistence in r d and innovative activities among external environmental factors market dynamism affects r d and innovation regarding firm specific characteristics size and outsourcing also have a positive impact on both processes past innovative behaviour is clearly more decisive in explaining the current state of r d and innovation activities than external factors or firm level heterogeneity

forms of trust and conditions for their stability of the three principal approaches to trust we decided to investigate in greater detail the one in which trust is regarded as a belief that the individuals involved hold about a relationship trust was defined as a delegatory relationship based on anticipation of the delegatee s behaviour we reached four main conclusions first the solution to the problem posed by the indeterminacy of trust lies in the differentiation and hierarchisation of the various forms of trust contractual organisational and tacit on the basis of their degree of irreversibility and stability second contractual trust is unstable because it comes up against the problem of guarantees of individual intentions this leads to the third conclusion rational evaluation by individuals cannot by itself establish trust which is based on collective beliefs practices and rules fourth we identified two conditions for the stability of trust the creation of irreversibilities through adherence to a rule and the creation of a confidence interval within which different interpretations of contradictory individual strategies are tolerated thus the viability of the various forms of trust depends on the ability of institutions and organisations to create rules that are likely when applied to produce an interval in which tolerance of mutual intentions is the norm these analyses of trust hence highlight the role of time and period of time in the notion of trust

technological discontinuities and the challenge for incumbent firms destruction disruption or creative accumulation the creative destruction of existing industries as a consequence of discontinuous technological change is a central theme in the literature on industrial innovation and technological development established competence based and market based explanations of this phenomenon argue that incumbents are seriously challenged only by competence destroying or disruptive innovations which make their existing knowledge base or business models obsolete and leave them vulnerable to attacks from new entrants this paper challenges these arguments with detailed empirical analyses of the automotive and gas turbine industries we demonstrate that these explanations overestimate the ability of new entrants to destroy and disrupt established industries and underestimate the capacity of incumbents to perceive the potential of new technologies and integrate them with existing capabilities moreover we show how intense competition in the wake of technological discontinuities driven entirely by incumbents may instead result in late industry shakeouts we develop and extend the notion of creative accumulation as a way of conceptualizing the innovating capacity of the incumbents that appear to master such turbulence specifically we argue that creative accumulation requires firms to handle a triple challenge of simultaneously a fine tuning and evolving existing technologies at a rapid pace b acquiring and developing new technologies and resources and c integrating novel and existing knowledge into superior products and solutions

environmental policy and stable collusion the case of a dynamic polluting oligopoly we show that the imposition of a markovian tax on emissions that is a tax rate which depends on the pollution stock can induce stable cartelization in an oligopolistic polluting industry this does not hold for a uniform tax thus accounting for the feedback effect that exists within a dynamic framework where pollution is allowed to accumulate into a stock over time changes the result obtained within a static framework moreover the cartel formation can diminish the welfare gain from environmental regulation such that welfare under environmental regulation and collusion of firms lies below that under a laissez faire policy

common property resources storage facilities and ownership structures a cournot model of the oil market during the last decade economists have tried hard to convince meadows and his followers that market forces do not tend to exhaust our natural resources too rapidly as compared with the requirements of an intertemporal pareto optimum it is well known now that under well defined property rights and correct price expectations a competitive extraction industry brings about a pareto optimal depletion path and it has been shown that oligopolistic and monopolistic market structures may even produce a bias towards conservation 1 it is still an unresolved issue however which extraction path will result if property rights are imperfectly defined following the pioneering work of gordon 1954 there has been a large body of literature demonstrating that in the extreme case of free entry and myopic profit maximization there are strong reasons for excessive extraction 2 but this literature hardly yields reliable conclusions for the perhaps more realistic case where firms derive their behaviour from intertemporal optimization and where there is a common ownership but limited access to the resource the basic intuition behind the common pool problem is that the individual agent chooses an extraction policy other than the one he would choose under well defined property rights since he is afraid that part of the resource he leaves underground will be extracted and sold by others 3 despite the simplicity of this intuition there does not seem to be any publication that analyses it within an intertemporal equilibrium model with rational and far sighted agents this is the motivation for the present approach the approach studies the common pool problem in the context of an oligopolistic world market for oil it posits a given number of identical firms extracting oil from holdings between some of which there is mutual seepage the firms sell the extracted oil in the same market or they store it in privately owned seepage proof tanks each firm derives its behaviour from intertemporal optimization under perfect foresight of the time paths of the model variables but cournotesque conjectures about the reactions of its competitors except for the assumption of storage facilities this specification is closely related to models previously studied by khalatbari 1977 and kemp and long 1980 essay 10 4 the two models are very similar but they yield strikingly different conclusions while kemp and long find that the extraction path chosen by the firms is pareto optimal i e that the price of the resource rises at a rate given by the market rate of interest khalatbari contends that there is over extraction kemp and long convincingly demonstrate that khalatbari s model suffers from an inconsistency in the way the individual firm expects its rivals to respond to its own actions and they argue that this inconsistency is the reason for the divergence in results thus the casual reader gets the

persistence of innovative activities sectoral patterns of innovation and international technological specialization abstract in this paper we focus on the role of persistence and heterogeneity of innovative activities at the level of the firm in determining the patterns of technological change in different industries and countries we ask are persistence and heterogeneity associated with higher degrees of concentration in innovative activities stability in the ranking of innovators and lower degrees of entry and exit in the population of innovators or do the patterns of innovation depend on other variables like firm size and industrial concentration moreover what are the relationships between the patterns of innovative activities their determinants and the technological specialization of countries we compute indicators of persistence and heterogeneity using the otaf spru patent database at the firm level for five european countries over the period 1969 1986 for 33 technological classes then we estimate the relationships between our indicators of the sectoral patterns of innovative activities and international technological specialization on the one hand and our indicators of persistence heterogeneity and market structure on the other results show that persistence and asymmetries are important and strongly related phenomena that affect the patterns of innovative activities across countries and sectors while the role of market structure variables is less clear finally international technological specialization is associated to a competitive core of persistent innovators

persistence of innovation in unstable environments continuity and change in the firm s innovative behavior abstract the concept of persistence is generally used to define the positive relationship between past and present innovations which is explained by feedback and accumulation processes triggered by the firm s past results this paper states that changes in the economic or institutional conditions of the environment impact on the type of profitable innovations and past innovations might not be suitable for the new environment as a result firm s innovative behavior might change which means that the firm s set of decisions about engaging in the seek for innovations or not and if so the set of investments and capabilities it allocates to innovate could be modified empirical evidence is provided to reject the persistence hypothesis and to show that past innovations do not necessarily impact present ones this paper examines the relationship between past and present innovations for a group of argentinean firms during 1998 2006 which coincides with a period of macroeconomic instability results suggest that persistence has to be analyzed in terms of a dynamic firm s innovative behavior regardless of its results and how it allows the firm to accumulate competences and resources which increases the odds of successfully responding to changes in the environment and continuing to innovate

foreign direct investment and total factor productivity growth new macro evidence although the role of foreign direct investment fdi in facilitating technology transfer is well known in the literature empirical evidence regarding the effect of fdi on growth is mixed the contradictory results in the literature may be due to the failure to account for endogeneity and for the abortive capacity of the hosting countries using panel data for 49 countries over the period 1974 2008 and the existence of investment promotion agencies in the receiving countries as an instrument our results show that increased fdi stock leads to higher productivity growth we also find a significant positive effect on the interaction between fdi stock and distance to the technological frontier suggesting that the ability of technologically backward countries in absorbing technologies developed at the frontiers increases as more fdi stock is accumulated

phasing the operation mode of foreign subsidiaries reaping the benefits of multinationality through internal capital markets the lifetime of foreign equity partnerships is often limited research suggests that mncs abandon their local partners when the need for sharing ownership in foreign subsidiaries has diminished this study shows that mncs may abandon their local equity partners to reap the benefits of multinationality as mncs gain a competitive advantage from leveraging resources across borders they will initially benefit from sharing ownership with a local firm to embed their foreign subsidiaries in the local environment and access local resources more effectively later they will benefit from taking over the local partner s equity share to better embed their subsidiaries in the parent organization and transfer locally accessed resources to the mnc s other locations moderated mediation regressions provide evidence of such practice in the context of cross border transfers of capital resources this strategy seems to work as a corollary of our model panel regressions suggest that sharing ownership with local firms in a host country with a capital resource advantage is associated with appropriating more capital resources from the local debt market while abandoning these partner firms later is associated with transferring more capital resources from this host country via internal capital markets to other parts of the mnc

expectations the commons and optimal group size abstract this article derives a formula for the optimal number of exploiters of a commons whose output is sold in an imperfectly competitive market and whose exploiters hold nonzero or non nash conjectures we express the optimal number of exploiters in terms of the conjecture the elasticity of input productivity and the price elasticity of market demand consistent conjectures those that agree with reality imply the full tragedy of the commons and zero profits for the exploiters

simple solutions to the initial conditions problem in dynamic nonlinear panel data models with unobserved heterogeneity i study a simple widely applicable approach to handling the initial conditions problem in dynamic nonlinear unobserved effects models rather than attempting to obtain the joint distribution of all outcomes of the endogenous variables i propose finding the distribution conditional on the initial value and the observed history of strictly exogenous explanatory variables the approach is flexible and results in simple estimation strategies for at least three leading dynamic nonlinear models probit tobit and poisson regression i treat the general problem of estimating average partial effects and show that simple estimators exist for important special cases copyright 2005 john wiley sons ltd

the dynamic capabilities of firms an introduction an expanded paradigm is needed to explain how competitive advantage is gained and held firms resorting to resource bas ed strategy attempt to accumulate valuable technology assets and employ an aggressive intellectual property stance however winners in the global marketplace have been firms demonstrating timely responsiveness and rapid and flexible product innovation along with the management capability to effectively coordinate and redeploy internal and external competences this source of competitive advantage dynamic capabilities emphasizes two aspects first it refers to the shifting character of the environment second it emphasizes the key role of strategic management in appropriately adapting integrating and re configuring internal and external organizational skills resources and functional competences toward changing environment 3 only recently have researchers begun to focus on the specifics of developing firm specific capabilities and the manner in which competences are renewed to respond to shifts in the business environment the dynamic capabilities approach provides a coherent framework to integrate existing conceptual and empirical knowledge and facilitate prescription this paper argues that the competitive advanis tage of firms stems from dynamic capabilities rooted in high performance routines z operating inside the firm embedded in the firm s processes and conditioned by its history it offers dynamic capabilities as an emerging paradigm of the modern business j firm that draws on multiple disciplines and advances with the help of industry studies in the usa and elsewhere

the commons and the optimal number of firms the problem of the commons is a frequently cited example of market failure in which exploiters pursuit of profits does not lead to the attainment of a social or pareto optimum in particular a free access equilibrium induces an unrestricted number of exploiters or firms to equate the variable input s average product instead of its marginal product to the input s real rental rate hence the rents of the variable input are driven to zero haveman 1973 1 when the number of firms in a commons is unrestricted the scarce factor e g the fishery the hunting ground is not imputed a rent a social optimum can be achieved if a single firm exploits a commons and sells its output in a perfectly competitive market weitzman 1974 the purpose of this note is to derive an expression for the optimal number of firms exploiting a commons when the resulting output is sold in an imperfectly competitive market 2 since demand inelasticity due to monopoly power leads to overconservation while an increase in the number of exploiting firms typically leads to underconservation a finite number of firms for a commons can be found corresponding to a social or pareto optimum in particular the optimum number of firms depends directly on the elasticity of the input productivity and inversely on the price elasticity of market demand

innovation strategies as a source of persistent innovation an important topic in the recent literature on firms innovation is the question of whether and to what extent firms which innovate once have a higher probability of innovating again in subsequent periods this phenomenon is called the persistence of innovation although the literature has established that innovation persistence is indeed important from an empirical point of view relatively little attention has been paid to identifying the reasons why this is the case in this article we contribute to the literature by proposing that differences in innovation strategies across firms are an important driving force behind innovation persistence we analyses this issue using a panel database constructed from r d and community innovation surveys in norway empirical measures of five innovation strategies are identified by means of an inductive method ad hoc supplier based market driven r d intensive and science based a dynamic random effects probit model is used to estimate whether and to what extent these innovation strategies are a source of persistent innovation the results support the idea that the differences in innovation strategies across firms are an important determinant of the firms probability to repeatedly innovate more concretely we found that firms pursuing the strategies market driven r d intensive and science based were more likely to be persistent innovators we also distinguish the effects of strategy differences on the persistence of product and process innovation in all firms and within high tech versus low tech firms

common pool resource appropriation under costly cooperation abstract in addition to the usual fixed costs we introduce variable costs in a community s effort to cooperate in extracting from a common pool resource using a standard supervision mechanism these variable costs are shown to be an increasing function of individual members incentives to default the model explains why we frequently observe communities that all cooperate and have relatively similar resource endowments and yet achieve very different levels of extraction

technological regimes and the persistence of first mover advantages this article investigates first mover and early entrant advantages in terms of market share and its growth by analyzing a unique panel data set of korean manufacturing firms specifically this article examines the existence and persistence of first mover and early entrant advantages across different technological regimes we find that these advantages are influenced by characteristics of the firms as well as of the technological regimes under which they operate in general early entry into a market benefits a firm in terms of the size and growth rate of its market share early entrants including first movers have higher market shares except in regimes with high technological opportunity and low r d appropriability however first movers are disadvantaged in terms of market share growth except in regimes with low technological opportunities and high r d appropriability we also find that firm specific competences in r d and advertising help to maintain attenuate first mover and early entrant advantages disadvantages copyright 2011 the author 2011 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

foreign direct investment co2 emissions nexus in middle east and north african countries importance of biomass energy consumption abstract this study examines the association between foreign direct investment fdi and carbon emissions for the middle east and north african mena region in 1990 2015 including biomass energy consumption as an additional determinant of carbon emissions we apply the generalized method of moments gmm to validate the existence of the pollution haven hypothesis phh the n shaped association is also validated between fdi and carbon emissions the link between economic growth and carbon emissions is inverted u and n shaped that is it satisfies the environmental kuznets curve ekc hypotheses biomass energy use lowers carbon emissions and the causality analysis reveals that fdi causes co2 emissions clearly the results confirm the existence of a feedback effect between economic growth and carbon emissions the connection between biomass energy use and co2 emissions is also bidirectional the empirical findings suggest policy makers to design comprehensive trade and energy policies by targeting the cleaner production practices for not only to ensure environmental sustainability but also to fulfil the objectives of sustainable development goals

what happens to gazelles the importance of dynamic management strategy the starting point of this study is gibrat s law which is contrasted with strategic management this logic is subsequently applied to a group of remarkably dynamic high growth firms gazelles strategic management theory emphasises the importance of firms adjusting strategies in response to changes in the external environment in our study it is used to explain several key empirical findings using a novel british data set containing information on more than 100 gazelles these findings help explain 1 why gibrat s law of random firm growth processes does not generally hold 2 which strategy and environmental variables have a predictable influence on firm performance and 3 why routine application of best practice strategies is unlikely to foster firm growth in a changing economic environment in so doing this paper contributes to the large body of literature on small firm growth

efficiency inducing tax for a common property oligopoly the author characterizes the markov perfect tax that induces a common property oligopoly to extract efficiently a nonrenewable resource for linear and isoelastic demand he provides closed form expressions of the unique specific tax industry profits may be higher or lower in the oligopoly with the tax relative to the competitive equilibrium with property rights for linear or isoelastic demand there exists no feasible open loop tax that induces efficient extraction in this case the policymaker gains no advantage from being able to make binding commitments copyright 1992 by royal economic society

fdi and economic growth new evidence on the role of financial markets this study uses a threshold regression model and finds new evidence that the positive impact of fdi on growth kicks in only after financial market development exceeds a threshold level until then the benefit of fdi is non existent

international capital mobility and unemployment dynamics empirical evidence from oecd countries we use a panel of 20 oecd countries over a 30 year period to estimate the implications of international capital mobility for unemployment we nd that the increase in capital ows since the mid 1980s has contributed to an ampli cation of the impulse response of unemployment to country speci c shocks and to a fall in the persistence of unemployment in response to the same shocks

remittances and financial development empirical evidence from heterogeneous panel of countries remittances are the second largest source of external finance after foreign direct investment in the developing economies in this study we analyse the role of incoming remittances on financial de

is energy security a driver for economic growth evidence from a global sample abstract this study examines whether energy security contributes to economic growth for a global sample of 74 countries covering the period from 2002 to 2013 the benchmark model is built based on an extended version of the cobb douglas production function ten measures of energy security are employed to capture five aspects of energy security including availability accessibility acceptability affordability and develop ability besides the whole sample we also conduct the panel data analysis on subsamples of countries based on different income levels using panel corrected standard errors pcse and feasible generalized least squares fgls techniques that correct for heterogeneity and autocorrelation and produce robust standard errors the empirical results appear to be relatively robust to these two estimation techniques overall we find that energy security enhances economic growth for both the whole sample and subsamples of countries meanwhile energy insecurity measured by energy intensity and carbon intensity variables has a negative impact on economic growth the results vary across subsamples for several cases the findings imply that at the global level energy for economic development energy security and climate change mitigation should be pursued as integrated themes since there are linkages among these three agendas

theorizing path dependence a review of positive feedback mechanisms in technology markets regional clusters and organizations the concept of path dependence has often been criticized as vague and only narrowly applicable although we can find some very refined definitions of the concept we also find a wide range of empirical phenomena being described as path dependent we argue that more detailed accounts of the positive feedback mechanisms that form paths can take path dependence beyond this state of being overdetermined but under specified reviewing three well described cases of path dependent dynamics in technology markets regional clustering and organizations we define a core set of positive feedback mechanisms that constitute path dependence at different analysis levels and clarify the relationship between positive feedback and increasing returns we show that path dependent processes that is processes driven by positive feedback that veer toward rigidity or lock in can be but do not have to be found under many labels including structural inertia coevolution or institutional persistence we conclude that a precise definition of path dependence does not need to be at odds with the concept s widespread use in understanding organizational and industrial development processes copyright 2013 the author 2012 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

inefficient standard adoption inertia and momentum revisited i introduction since the establishment of the theory of network effects economists have been concerned with the question of whether a market with network effects will tend to settle on the socially optimal standard it has been postulated that markets may exhibit excess inertia once a technological standard is in place a new superior standard may not displace it because of installed base effects alternatively markets may exhibit excess momentum consumers may adopt a new standard too quickly ignoring the stranding effect they are having on previous users similar issues arise in the adoption of language and social norms the literature has investigated various conditions under which one of these inefficiencies arises such inefficiencies are of particular concern for open technologies such as the qwerty and dvorak keyboards 1 the situation is somewhat different when individual firms own standards in that case a simple argument seems to indicate that there is no possibility that an inefficient standard will persist if a new standard is superior in any objective sense there are gains to be made from switching to it once the standard has been adopted the firm can appropriate these gains therefore the firm has incentive to lower the initial price enough to induce adoption of the standard the preceding argument is made in liebowitz and margolis 1999 and repeated in spulber 2002 spulber expresses a general skepticism about the likelihood of inefficiencies when property rights are defined and markets exist critics might claim that previous models that imply inefficient standard adoption are unrealistic in some way and that if such models were modified slightly the inefficiency would disappear i reconsider the issue of inefficient standard adoption using a parsimonious yet compelling model assuming only that there are successive generations of finitely lived consumers that preferences are heterogeneous and that there are network effects among users adoption decisions can be inefficient this is true even if consumers can coordinate efficiently within a generation and a firm can act as a coordinating device across generations the model presented here generates some of the same results found in other papers collectively but in a more general setting and with more robust results if there is an established standard and a superior alternative emerges no single generation of consumers will be willing to switch to the new standard if the switching cost the loss of network benefit from breaking with past users is too high it may be that the benefits to future generations of consumers are large enough that from a social standpoint it would be efficient for one generation to adopt the new standard even if it is privately optimal for that generation to retain the old standard on the other hand the current generation considers only its own switching cost and not the cost it imposes on the previous generation leading to potential overadoption of new technology even for proprietary standards it is not clear that the incentive of the firm to induce adoption matches the social incentive in particular if consumer preferences are heterogeneous the firm will not be able to price in such a way to extract all of the additional surplus gained from the new standard on the other hand the firm will be able to appropriate some of the surplus generated by the network effect itself which is present for any standard and thus does not affect the social incentive to change standards it is not possible to address this issue with a two period model as in some of the previous literature see for example choi 1994 choi and thum 1998 katz and shapiro 1986 if a new technology is introduced in the second period but then the game ends the welfare of future generations of consumers is neglected 2 this article also differs from previous infinite horizon models of technology adoption

institutional quality thresholds and the finance growth nexus using an innovative threshold estimation technique this study examines whether the growth effect of financial development in countries with distinct levels of institutional development differs the results demonstrate that there is a threshold effect in the finance growth relationship specifically we found that the impact of finance on growth is positive and significant only after a certain threshold level of institutional development has been attained until then the effect of finance on growth is nonexistent this finding suggests that the financial development growth nexus is contingent on the level of institutional quality thus supporting the idea that better finance i e financial markets embedded within a sound institutional framework is potent in delivering long run economic development

are differences in firm size transitory or permanent an erratum for this article has been published in journal of applied econometrics 18 2 2003 249 previous empirical work on corporate growth rates using cross section or short panel econometric techniques suggests that growth rates are random but that some degree of mean reversion exists this means that size differences between firms are transitory another more natural way to explore the long run distribution of firm sizes is to examine data on the growth of particular firms over long periods of time using a sample of 147 uk firms observed continually for more than 30 years our conclusions are that growth rates are highly variable over time and that differences in growth rates between firms do not persist for very long further firms show no tendency to converge to either a common size or to a pattern of stable size differences over time these results are compared and contrasted with standard approaches that suggest that firms reach and maintain stable positions in a skewed size distribution copyright 2002 john wiley sons ltd

mitigating the tragedy of the commons through cooperation an experimental evaluation abstract in a commons each firm s costs rise with industry output this externality can be mitigated if firms jointly restrict harvests but higher prices result repeated interaction usually facilitates cooperation that lowers harvest rates increased cooperation suggests there should be more firms in the socially optimal market structure using experimental markets with two to five firms we observe the influence of industry size on harvest rates cooperation increases the socially optimal number of firms in markets when there are static externalities but not for dynamic externalities finally even when the initial stock is low there is little tendency toward resource extinction

harvesting preemption industrial concentration and enclosure of national marine fisheries this paper explores how harvesting technology can affect firms internalisation of common pool externalities and the incentives for expanding firm s size focusing on supply side non pecuniary externalities our closed entry harvesting competition model suggests that when marginal harvesting costs are weakly sensitive to common pool externalities atomistic competition is likely to remain other things equal as the predominant industrial structure in the fishery the avenue for increasing industrial concentration is modelled via stackelberg leadership which offers the option of preempting rivals production in our static modelling a fishery subject to stackelberg signalling results in higher overfishing versus the case of a highly decentralised harvesting sector proxied by the use of nash conjectures given that static optimising behaviour could be interpreted as a result of entry controls and other fishing regulations being widely perceived as ineffective controls the obtained overfishing ranking suggests that in fisheries where strategic preemption in production is feasible but where entry controls and other important regulations on fishing effort are considered to be ineffective overfishing is likely to remain the predominant outcome even if other incentives promote evolution towards a more concentrated industry structure when the fishery is already overpopulated by numerous small firms whatever advantages large firms may have in terms of profitability numerous small scale fishermen tend to make up for in the political arena this imposes constraints on the politically feasible fishing regulations we use a second best welfare benchmark to illustrate resulting policy trade offs

is there persistence in innovative activities abstract this paper examines firm innovative persistence using patent applications of 577 uk manufacturing firms non parametric techniques show the empirical distributions of patents are neither geometric nor poisson there exists a threshold effect represented by the first patent the probability to go from zero to one patent is uniformly much lower than from n to n 1 patents with n 1 transition probability matrices show little persistence in general but strong persistence among great innovators that account for a large proportion of patents requested innovative activities at least which are captured by patents are persistent there is heterogeneity across industrial and size classification

productivity growth persistence firm strategies size and system properties this paper investigates the dynamics of productivity in a large sample of italian manufacturing firms focusing on the determinants of firm level persistence in time of high total factor productivity tfp growth rates relative to the corresponding sectoral distributions in particular we assess the impact of both the internal characteristics of companies including size and management strategies and external systemic conditions including business cycles and regional innovation performance in order to disentangle the effects of the mix of internal and systemic factors in shaping firm level persistence we implement both transition probability matrices and dynamic probit models results reveal the presence of significant persistence in tfp growth rates such persistence turns out to be path dependent since it is shaped by a number of complementary and contingent factors that locally affect the dynamics of the process

outsourcing in a global economy we study the determinants of the location of subcontracted activity in a general equilibrium model of outsourcing and trade we model outsourcing as an activity that requires search for a partner and relationship specific investments that are governed by incomplete contracts the extent of international outsourcing depends inter alia on the thickness of the domestic and foreign market for input suppliers the relative cost of searching in each market the relative cost of customizing inputs and the nature of the contracting environment in each country

the optimal number of firms in the commons a dynamic approach we consider a common property resource sold in imperfectly competitive markets there is a dynamic externality current harvests lower future stocks raising future harvest costs and a static crowding externality increasing industry size raises costs but lowers prices thus it has ambiguous welfare effects the optimal industry size typically changes over time so that a first best outcome cannot be obtained with a fixed number of firms single firm exploitation is optimal only under special circumstances the socially optimal open loop steady state industry size corresponds to the static optimum both generally differ from the closed loop steady state optimum

the persistence of innovative activities abstract this paper examines the persistence of innovative activities at the firm level in a comparative perspective a new data set is used composed of six panel data one for each of the following countries france germany italy uk japan and the usa for each country we use data on patent applications to the european patent office in the period 1978 1993 by 1200 1400 manufacturing firms using a transition probability matrix tpm approach we find evidence for the existence of persistence in innovative activities although it is not very high in the aggregate and it declines as time goes by however both great innovators and non innovators have a high probability to remain in their state and persistent innovators originate a disproportionate share of innovative activities in this sense persistence in innovative activities is quite strong these tendencies apply to all countries considered here although clear country specific properties are observed moreover there is heterogeneity also across industrial and size classification intersectoral differences are invariant across countries suggesting that persistence is at least partly a technology specific variable persistence tends to increase with firm size but the relationship between firms size and persistence is strongly country specific and it is not a simple one

the causality between fdi and sector specific production in turkey evidence from threshold cointegration with regime shifts abstractthis article considers bidirectional nonlinear cointegration relation between fdi and industrial output in turkey the data cover the monthly period 2005 1 2013 10 for the time series of total industrial production 36 sub industrial sectors production and fdi following nonlinear threshold cointegration and vecms the article yields that i total industrial production and nine sub industrial productions have positive long run impact on fdi with significant error corrections ii six sub industrial productions have short term influence on fdi iii fdi has long run positive impulse on total industrial production and nine sub industrial productions with some significant error corrections and iv fdi affects four sub industrial productions in the short run as well as in the long run the results of vecms from i also reveal that the all short term adjustment parameters are found significant and powerful in 10 typical regimes regime 1s and in 5 extreme regimes regime 2s finally the outcom

innovation persistence survey and case study evidence abstract evidence on the persistence of innovation sheds light on the nature of the innovation process and can guide appropriate policy development this paper examines innovation persistence in ireland and northern ireland using complementary quantitative and case study approaches panel data derived from innovation surveys is used and suggests very different results to previous analyses of innovation persistence primarily based on patents data product and process innovation are found to exhibit strong general persistence but we find no evidence that persistence is stronger among highly active innovators our quantitative evidence is most strongly consistent with a process of cumulative accumulation at plant level our case studies highlight a number of factors which can either interrupt or stimulate this process including market volatility plants organisational context and regulatory changes notably however the balance of influences on product and process innovation persistence differs with product innovation persistence linked more strongly to strategic factors and process changes more often driven by market pressures

service offshoring and productivity evidence from the us the practice of sourcing service inputs from overseas suppliers has been growing in response to new technologies that have made it possible to trade in some business and computing services that were previously considered non tradable this paper estimates the effects of offshoring on productivity in us manufacturing industries between 1992 and 2000 it finds that service offshoring has a significant positive effect on productivity in the united states accounting for around 10 per cent of labour productivity growth during this period offshoring material inputs also have a positive effect on productivity but the magnitude is smaller accounting for approximately 5 per cent of productivity growth

entry deterrence and overexploitation of the fishery abstract two stackelberg game models open access and restricted entry of a poaching fishery situation are proposed only the long run noncooperative solution of managing resource stocks is assumed feasible the optimal stock under open access for poachers is shown to be lower than under restricted entry and the latter to be lower than under exclusive ownership deterrence is completely successful under open access but is partially successful only under restricted entry the game models considered are shown to be equivalent to a constrained ownership fishery control problem or its surrogate

on the existence of cournot equilibrium this paper examines the existence of n firm cournot equilibrium in a market for a single homogeneous commodity it proves that if each firm s marginal revenue declines as the aggregate output of other firms increases which is implied by concave inverse demand then a cournot equilibrium exists without assuming that firms have nondecreasing marginal cost or identical technologies also if the marginal revenue condition fails at a potential optimal point there is a set of firms such that no cournot equilibrium exists the paper also contains an example of nonexistence with two nonidentical firms each with constant returns to scale production
