technological regimes schumpeterian patterns of innovation and firm level productivity growth the paper investigates the relationships between technological regimes and firm level productivity performance and it explores how such a relationship differs in different schumpeterian patterns of innovation the analysis makes use of a rich dataset containing data on innovation and other economic characteristics of a large representative sample of norwegian firms in manufacturing and service industries for the period 1998 2004 first we decompose tfp growth into technical progress and efficiency changes by means of data envelopment analysis we then estimate an empirical model that relates these two productivity components to the characteristics of technological regimes and a set of other firm specific factors the results indicate that 1 tfp growth has mainly been achieved through technical progress while technical efficiency has on average decreased 2 the characteristics of technological regimes are important determinants of firm level productivity growth but their impacts on technical progress are different from the effects on efficiency change 3 the estimated model works differently in the two schumpeterian regimes technical progress has been more dynamic in schumpeter mark ii industries while efficiency change has been more important in schumpeter mark i markets

improvement of technical efficiency of firm groups abstract cooperation between firms can never improve the technical efficiency of any firm coalition the directional distance function by virtue of its additive nature is a useful tool that outlines this impossibility in this paper the additive aggregation scheme of input output vectors is generalized according to an aggregator accordingly cooperation between firms may increase the technical efficiency of the firm group this improvement is shown to be compatible with nonjoint semilattice technologies that bring out either output or input weak complementarity firm games are investigated to show that firms may merge on the basis of their inputs due to constraints imposed on outputs conversely they may merge with respect to the outputs they can produce because of limitations imposed on inputs

technological activity and survival of firms abstract the paper presents new evidence on the effect of technological activity on the post entry performance of firms by comparing firm survival across technical and non technical products and over stages of differing technological activity it attempts to resolve two seemingly contradictory hypotheses that uncertainty inherent in high technological activity reduces the probability of survival and that technological activity increases the probability of entrant survival the empirical results in the context of the product life cycle framework show that entering firms enjoy a higher probability of survival in stages of high technological activity and in products that are more technical in nature however the hazard function the probability of failure conditional on age is higher for technical products reflecting the adverse effects of technical uncertainty and obsolescence of incumbent knowledge

political aspects of innovation abstract political aspects that enhance but also undermine the positive transformational power of public innovation policies are examined as such this paper follows michal kalecki in his 1943 paper that identifies the political aspects which enhance and undermine the positive transformational power of keynesian full employment policies similarly this paper provides a policy framework that identifies what government and business support as innovation policies the role of innovation stems from schumpeter s long run perspective but incorporates the more dynamic cyclical short term and trend perspectives of kalecki this paper critiques the strategy of public innovation policy in general and derives policy implications

labour market deregulation flexibility and innovation labour flexibility is often portrayed as important to competitive success using evidence from an original survey of uk firms this paper investigates the relationships between firms use of on the one hand various flexible work practices human resource management techniques and industrial relations systems and on the other hand the innovative activities of those firms our results suggest that the sort of low road labour flexibility practices encouraged by labour market deregulation short term and temporary contracts a lack of employer commitment to job security low levels of training and so on are negatively correlated with innovation

business segmentation and location revisited innovation and the terra incognita of large firms hayter r patchell j and rees k 1999 business segmentation and location revisited innovation and the terra incognita of large firms reg studies 33 425 442 this paper revisits ideas about the relationships between business segmentation and location by articulating the characteristics and roles of large firms lfs the well known dual model of business segmentation with its emphasis on the polar cases of small firms and giant multinationals portrays a static exploitative picture of these relationships and does not relate well to the complexity of industrial organization or the size distribution of firms explicit recognition of lfs however draws attention to the processes generating segmentation and to the permeability of segment boundaries in which bargaining and learning are interdependent relationships a triad model of business segmentation based on porter s ideas of competitive strategy is outlined which reveals the vital role of lfs as innovators the model is illustrated heuristical

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

technological regimes and schumpeterian patterns of innovation this paper proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological learning regimes a technological regime is defined by the particular combination of technological opportunities appropriability of innovations cumulativeness of technical advances and properties of the knowledge base building upon the distinction between schumpeter mark i and schumpeter mark ii industries this paper provides empirical estimates of the relationships between indicators of the schumpeterian patterns of innovation concentration of innovative activities stability in the hierarchy of innovators and importance of new innovators and indicators of the variables defining technological regimes

empirical patterns of firm growth and r d investment a quality ladder model interpretation we present a partial equilibrium model of endogenous firm growth with r d investment and stochastic innovation as the engines of growth drawing on the quality ladder models in the macro growth literature and the literature on patent races and the discrete choice models of product differentiation the model fits a number of empirical patterns well including i a skewed size distribution of firms with persistent differences in firm sizes ii firm growth independent of firm size as stated in the so called gibrat s law and iii r d investment proportional to sales

tangible and intangible sunk costs and the entry and exit of firms in a small open economy the case of austria the paper provides evidence on the role of sunk costs as mobility barriers an empirical study of the austrian manufacturing industry explicitly considers sunk costs related to investment in dedicated intangible assets the results confirm the relevance of sunk costs as mobility barriers their symmetry with respect to entry and exit and show that the influence of sunk costs is robust to aggregation

technology and the demand for imports in the pure theory of international trade traded goods are generally viewed as finished products this is in sharp contrast with the fact that the bulk of world trade is in intermediate products to reconcile theory with facts a number of models of trade in intermediate products have been proposed in recent years most of these models have been used to investigate the validity of well known trade theorems in the presence of intermediate products 2 hence most of these models are rather complex generally allowing for two factors of production and two final goods as well as for one or two pure intermediate products 3 another feature common to most of these models and that is borrowed from standard trade theory is the assumption that production is nonjoint in input quantities 4 this assumption leads to a number of remarkable theoretical results but it also greatly increases the number of possible patterns of production and of interindustry flows and it thus adds to the complexity of the models furthermore if the number of goods is larger than the number of factors nonjointness leads to indeterminacy unless additional assumptions are made 6 these assumptions typically are that some goods are not produced domestically 7 or that some goods are not traded internationally 8 this further multiplies the number of possible cases and it explains perhaps why none of the models proposed so far has emerged as the benchmark model much in the same way as for

unobservable industry characteristics and the innovation concentration advertising maze evidence from an econometric study using panel data for manufacturing industries in the frg 1979 1986 in discussing the nexus between innovations and market structure it is often argued that industry characteristics called opportunities might play an important role as determinants of innovation and that simultaneity rather than one way causality prevails we consider a three equation model for innovation advertising and concentration based on pooled cross section time series data for 26 german manufacturing industries we estimate single equation models with and without fixed industry and or time effects to control for unobservable industry or time effects respectively and simultaneous equation systems including fixed effects and controlling for extreme cases outliers or not furthermore we use two different measures for innovations i e the percentage of shipments due to new products and the percentage of firms which classified themselves as innovators our results can be summarized as follows 1 the firm size has no significant effect on innovation one can therefore not conclude from this data set that large firms are more innovative than small ones 2 unobservable industry effects do matter 3 the treatment of outliers does matter 4 simultaneity does matter 5 the way innovations are measured does matter 6 different stories could be told based on the results of the systems of interdependent equations estimated

technological regimes catching up and leapfrogging findings from the korean industries abstract this paper examines the experiences of selected industries in korea to identify the stylized facts in the process of technological capability building and thereby to sort out the conditions for the catching up to occur to explain the process we have built a model of technological and market catching up a special attention has been given to the question of whether there has been a case of leapfrogging in any industry in korea and if so what are the conditions for its incidence in our framework we first measure the degree of catching up in terms of market shares in the world then we focus on catching up in technological capabilities in explaining the different record and prospects of korean industries in market catching up in the model technological capability is determined as a function of both technological effort and the existing knowledge base as determinants of technological effort we look at the technological regimes of the industries such as cumulativeness of technical advances fluidity predictability of technological trajectory and the properties of knowledge base using this model we explain the different technological evolution of the selected industries in korea including the d ram automobile mobile phone consumer electronics personal computer and machine tool industries we find three different patterns of catching ups path creating catching up cdma mobile phone path skipping catching up d ram and automobile and path following catching up consumer electronics personal computers and machine tools we interpret the first two case of catching up as leapfrogging unlike the argument by perez and soete perez c soete l 1988 catching up in technology entry barriers and windows of opportunity in dosi et al eds technical change and economic theory pinter publishers london we find that important r d projects except automobiles where only private r d was involved involved both private and public capacities and that entry was not driven by endogenous generation of knowledge and skills but by collaboration with foreign companies

on the relationship between firm size and export intensity export marketing literature supports the view that firm size is positively related to export intensity although the empirical findings have been mixed a number of theoretical arguments are used to support this proposition i e international marketing economies of scale limited managerial and financial resources of small firms decisionmaker s risk perception based on a large survey of the italian manufacturing industry the article falsifies the proposition and challenges some widely held assumptions in export marketing literature

exports and labor demand searching for functional structure in multi output multi skill technologies to simplify the representation of a technological relationship between inputs and outputs a production unit s technology must typically satisfy some restrictive conditions some of them being well known in the literature this article presents new results for aggregating labor inputs and outputs in terms of restrictions on elasticities of scale and substitution these conditions are then empirically investigated in a framework that is flexible and does not lose its flexibility after separability being imposed the empirical findings of the exact approach to aggregation are found to be rather pessimistic on the possibility of providing a simplified representation

the relationship between firm growth size and age estimates for 100 manufacturing industries this study uses a sample of all firms operating in 100 manufacturing industries to examine some aspects of firm dynamics it finds that firm growth the variability of firm growth and the probability that a firm will fail decrease with firm age it also finds that firm growth decreases at a diminishing rate with firm size even after controlling for the exit of slow growing firms from the sample gibrat s law therefore fails although the severity of the failure decreases with firm size copyright 1987 by blackwell publishing ltd

age size growth and survival uk companies in the 1980s this paper examines growth and survival amongst quoted and unquoted u k companies in the period 1975 85 and compares the results with earlier u k and u s studies an examination of death rates shows that smaller companies had higher death rates but the largest and smallest companies were least vulnerable to takeover careful attention is therefore paid to problems of sample selection bias it is shown that smaller companies grew faster than larger companies that gibrat s law does not hold amongst smaller firms that age is negatively related to growth and that these results are not an artifact of sample selection bias copyright 1994 by blackwell publishing ltd

r d appropriability opportunity and market structure new evidence on some schumpeterian hypotheses one of the largest bodies of literature in the field of industrial organization is devoted to the interpretation and testing of several hypotheses advanced by joseph schumpeter 1950 concerning innovation and industrial market structure one set of hypotheses focuses on the role of firm size as a determinant of r d spending and the rate of technological advance another set focuses on the effect of market concentration on r d and technological advance in this paper we reexamine the latter set of hypotheses at the industry level using new data on r d appropriability and technological opportunity collected by levin et al 1984 in a survey of r d executives in 130 industries

duality theory for variable costs in joint production duality methods for incomplete systems of consumer demand equations are adapted to the dual structure of variable cost functions in joint production this allows identification of necessary and sufficient restrictions on technology and cost so that con ditional factor demands can be written as functions of input prices fixed inputs and cost these are observable when variable inputs are chosen and committed to production hence the identified restrictions allow ex ante conditional demands to be studied using observable data this class of production technologies is consistent with all von neu mann morgenstern utility functions when ex post production and or output prices are un certain

managing innovation the pursuit of competitive advantage and the design of innovation intense environments abstract since the 1970s the field of innovation management has become the dominant policy discourse on the management of technological change specifically servicing the needs of government and business despite its rapid expansion in the 1980s discussion in this discourse has actually narrowed and key implicit assumptions about the nature of innovation and its appropriate management have remained relatively unquestioned in recent years attempts have been made to once again widen discussion this paper contributes to this widening of discussion through an examination of the way in which the pursuit of competitive advantage has shaped the discourse and policy instruments various policy instruments have been presented as bolstering national performance in global economic and technological positioning one of the newest is the innovation intense environment innovation intense environments iies are defined here as special spaces which purportedly increase the rate of innovation and proliferation of new high technology industries iies are referred to in the literature in a variety of ways including science or technology parks science cities or technopolises while there is substantial variation in iie design globally most examples are implicitly shaped by the overall drive for competitive advantage and rely on a very limited definition of innovation this shaping is clearly revealed when two very different kinds of iie designs are examined this paper examines fundamental assumptions made about the nature of innovation and its appropriate management as expressed in contemporary iie design the drive for competitive advantage has come to dominate public sector management of technological change and it is time that other issues were reintroduced into the dominant discourse on innovation management and iie design

non joint technologies the hypothesis of non jointness in input quantities separate production functions is well known and it plays an important role in many areas of economics in this paper we define three additional forms of non jointness which have received little or no attention in the literature and which might be relevant for the firm as well as for the representation of the aggregate technology we characterize all forms of non jointness in terms of variable profit and joint cost functions this yields a number of restrictions which are all testable empirically the assumption that production is non joint in input quantities separate production functions inputs allocated between the different production processes plays a crucial role in many areas of economic theory we need only think of international trade theory public finance macroeconomics growth theory or traded non traded good models of international finance in fact it is safe to say that more often than not production is assumed non joint in input quantities in multiple output models little work has been done to test the empirical validity of the assumption of non jointness in input quantities samuelson 1966 studies the characterization of non joint technologies in terms of the transformation function as pointed out by hall 1973 however samuelson s results do not seem very useful for econometric work hall studies the characterization of non jointness in input quantities in terms of the joint cost function this leads to a number of restrictions which can easily be imposed or tested for and which were used in empirical work by burgess 1976 and by kohli 1981 lau 1972 1978 finally characterizes non jointness in input quantities in terms of the profit function besides non jointness in input quantities lau also examines the case of non jointness in output quantities when an input can be cracked into several outputs in this paper we define two additional cases of non jointness and we characterize them in terms of the joint cost function and the variable or normalized restricted profit function the new forms of non jointness that we define may be useful to describe technologies at the level of the firm and may be even more so at the aggregate level some may be useful concepts in other areas of economics as well such as consumer theory by distinguishing between the various forms of non jointness one obtains a number of testable restrictions on the corresponding joint cost or variable profit functions

dynamics of competing with quality and advertising based goodwill goodwill formation is a complex process and many factors influence the formation of goodwill of a firm the implications of advertising enabled goodwill formation are reported in several articles in the research literature in this paper we extend this stream of research by including quality in the goodwill formation process we adopt a dynamic model of competition utilizing a differential game approach and derive expressions for open loop markovian nash equilibrium investments in advertising and quality the insights gained from the analysis of our model and from the equilibrium solutions are presented in the form of research propositions

technological regimes and firm survival evidence across sectors and over time in addition to the usual variables representing firm and industry specific features that impact the firm s survival this paper uses three r d related variables to reflect two schumpeterian technological regimes creative destruction the entrepreneurial regime and creative accumulation the routinized regime after controlling for age size entry barriers capital intensity the profit margin the concentration ratio the profit cost ratio and entry rates the empirical results confirm the theoretical relationship between technological regimes and the survival rate of new firms new firms are more likely to survive under the entrepreneurial regime moreover this effect is larger within the younger cohorts of firms than within the older ones

economics of scale and scope in multiproduct firms evidence from us railroads recently there has been a surge of interest in analysing scale economies in us railroad firms the analysis of scale economies in existing studies is however limited in view of recent advances in the theory of the multiproduct firm in this paper the previous work is extended to address the issue of scale and scope economies in multiproduct firms the findings show that us railroads experience mild overall economies of scale but rather marked product specific economies of scale with respect to both freight and passenger services however there appear to be diseconomies of scope associated with the joint production of the two services based on these results this study indicates that us railroad firms would have no tendency to behave as a natural monopoly in the absence of regulation

a simple theory of advertising as a good or bad our analysis treats advertisements and the goods advertised as complements in stable metautility functions and generates new results for advertising by building on and extending the general analysis of complements by assimilating the theory of advertising into the theory of complements we avoid the special approaches to advertising found in many studies that place obstacles in the way of understanding the effects of advertising we also use this approach to evaluate advertising from a welfare perspective whether there is excessive or too little advertising depends on several variables the effects on consumer utility the degree of competition in the market for advertised goods the induced changes in prices and outputs of advertised goods and whether advertising is sold to consumers

u s technology and the specific factors model abstract this paper reports empirical estimates of one of the most popular models of internaional trade theory the specific factors model the two outputs consumption goods and investment goods and two factors labor and capital are considered labor is assumed to be mobile between sectors while capital is assumed to be sector specific assuming that the relative supplies of the two types of capital are constant through time the model can be estimated with aggregate data even though the sector specific capital stocks are not observable empirical results show that the model does substantially better than under the heckscher ohlin production structure

non parametric analysis of multi output production with joint inputs we focus on analysing cost minimising production behaviour in multi output settings we distinguish between two approaches for modelling the use of joint inputs the cooperative approach assumes cost minimisation at the aggregate firm level while the non cooperative approach assumes cost minimisation at the level of the individual output division our framework extends the existing non parametric framework for analysing single output production an empirical application to the english and welsh drinking water and sewerage sector shows the practical usefulness of our framework specifically we compare the empirical validity of the cooperative and non cooperative models for describing the observed production behaviour

schumpeterian patterns of innovation using patent data for four countries germany france united kingdom and italy for the period 1968 1986 the authors find that the patterns of innovative activities differ systematically across technological classes while remarkable similarities emerge across countries in the patterns of innovative activities for each technological class this result strongly suggests that technological imperatives and technology specific factors closely linked to technological regimes play a major role in determining the patterns of innovative activities across countries schumpeter proposed two major patterns of innovative activities the first one labelled by nelson and winter 1982 and kamien and schwartz 1982 as schumpeter mark i is proposed in the theory of economic development 1934 in this work schumpeter examined the typical european industrial structure of the late nineteenth century characterised by many small firms according to this view the pattern of innovative activity is characterised by technological ease of entry in an industry and by a major role played by new firms in innovative activities new entrepreneurs come in an industry with new ideas new products or new processes launch new enterprises which challenge established firms and thus continuously disrupt the current ways of production organisation and distribution and wipe out the quasi rents associated with previous innovations the second one labelled schumpeter mark ii is proposed in capitalism socialism and democracy 1942 in this work inspired by the features of the american industry of the first half of the twentieth century schumpeter discussed the relevance of the industrial r d laboratory for technological innovation and the key role of large firms according to this view the pattern of innovative activities is characterised by the prevalence of large established firms and by relevant barriers to entry for new innovators large firms have institutionalised the innovation process with the creation of r d laboratories filled with researchers technicians and engineers with their accumulated stock of knowledge in specific technological areas their advanced competence in large scale r d projects production and distribution and their relevant financial resources they create barriers to entry to new entrepreneurs and small firms

blade runner economics will innovation lead the economic recovery according to schumpeterian theories economic expansions are associated with the introduction of successful new products processes and services while depressions are linked to stagnant periods with few innovations can the economic crisis set in motion in 2008 be explained by the inability to innovate and upgrade production and conversely will an economic recovery require a new stream of innovations drawing on the debate which emerged after the 1970s economic crisis this discussion paper tries to assess whether it is likely that the next long term expansion will be linked to a new stream of innovations while most evidence suggests that icts continue to provide the back bone of economic activities there is the prospect that biotechnology will eventually start to fulfil the promise envisaged over 30 years ago in the film blade runner

coordinating advertising and pricing in a manufacturer retailer channel abstract cooperative advertising is a practice that a manufacturer pays retailers a portion of the local advertising cost in order to induce sales cooperative advertising plays a significant role in marketing programs of channel members nevertheless most studies to date on cooperative advertising have assumed that the market demand is only influenced by advertising expenditures but not by retail price this paper addresses channel coordination by seeking optimal cooperative advertising strategies and equilibrium pricing in a two member distribution channel we establish and compare two models a non cooperative leader follower game and a cooperative game we develop propositions and insights from the comparison of these models the cooperative model achieves better coordination by generating higher channel wide profits than the non cooperative model with these features a the retailer price is lower to consumers and b the advertising efforts are higher for all channel members we identify the feasible solutions to a bargaining problem where the channel members can determine how to divide the extra profits

the voyage of the beagle into innovation explorations on heterogeneity selection and sectors the aim of the paper is to assess heterogeneity of the innovation process using exploratory factor analysis on micro data from the third community innovation survey in 13 countries we identify four patterns that can be interpreted as research user external and production ingredients of innovation all too often it is assumed that how firm innovate can be represented by differences across sectors and or countries to put this proposition under scrutiny we partition variability of the factors scores into components identified by these higher levels sectors and countries matter to a certain extent but far more of the variance is given by heterogeneity among firms within both of them however groups of firms produced by cluster analysis account for much higher share of the variance which indicates that the most relevant stratification of the data cuts across the established sectoral and national boundaries we discuss implications of these findings for understanding of selection in evolutionary economics and for the literature on innovation systems

the globalisation of technology a new taxonomy book synopsis international management of research and development brings together the most influential contributions to managing organising and coordinating r d and innovation on a global scale in addition to papers on the fundamental principles trends and drivers of international r d it covers strategies and operations of global r d it also provides an introduction to modern concepts such as knowledge networks open innovation and virtual innovation it is a key reference collection for professors researchers and practitioners

labour market regulation industrial relations and technological regimes a tale of comparative advantage in this paper we present comparative evidence from oecd countries concerning the impact of labour market institutions and regulations on technological specialization the interplay between the degree of labour market flexibility the system of industrial relations and the knowledge base of different industries determines the viability of different human resource strategies thereby shaping the patterns of comparative advantage our empirical results show that countries with coordinated industrial relations systems and strict employment protection tend to specialize in industries with a cumulative knowledge base we argue that two mechanisms explain these patterns the larger the scope for resorting to internal labour markets the lower the adjustment costs imposed by labour market regulation furthermore employment protection and coordinated industrial relations regimes by aligning workers and firms bjectives encourage firm sponsored training as well as the accumulation of firm specific competencies allowing firms to fully exploit the potential of the internal labour market copyright 2002 oxford university press

mobility and innovation a cross country comparison in the video games industry open labour markets are often seen as a precondition for innovation particularly for new industries however this view ignores two core findings of the economic systems literature first that mobility patterns are institutional microsystems that need to be complementary to other institutions in the labour market and second that new industries may be characterised by incremental and complex innovation based on these considerations we ask how mobility affects innovation in the video games industry in the us and japan we find that inter firm mobility is beneficial for innovation in the us but has negative effects in japan we further find that inter functional mobility is beneficial for innovation in both countries our analysis is based on career histories from the video games industry in the us and japan we present an empirical study based on the game development of 815 video games and the careers of 28 426 video game developers who were involved in the development of games released between 1999 and 2009

rent dissipation and efficient rationalization in for hire recreational fishing abstract recreational fisheries are increasingly important in fisheries management for some species recreational take rivals or exceeds the amount harvested by commercial fishermen most recreational fisheries are regulated with gear restrictions bag limits and time area closures but there is increasing interest in the market based solutions employed in commercial fisheries this despite the lack of an adequate bioeconomic theory of the joint commercial recreational aspects of many recreational fisheries this paper integrates a detailed production specification with traditional bioeconomic tools in order to better understand the implications of rationalization schemes targeted at the charter sector while confirming some of the qualitative conclusions of the commercial fisheries literature on open access and regulated open access our model also generates rich and novel predictions with respect to input choices the number of vessels and congestion externalities we devise a system of instruments that generate efficient outcomes and extensively discuss issues associated with their real world implementation

innovation in firms as the firm is the central mechanism for converting innovation into economic action this paper argues that economists and economic policy makers need to understand how and why firms innovate this is challenging because innovation manifests itself in a wide range of forms and results from diverse organizational processes the paper discusses a number of the practices supporting innovation in firms including positioning connecting protecting organizing and measuring a number of theories explaining innovation in firms are discussed the paper concludes that the determination of the most effective policy levers for encouraging innovation requires staying abreast of current and emerging innovation practices in firms

testing a model of exploration and exploitation as innovation strategies we suggest a structural model that specifies firm growth as a function of firm specific parameters market specific parameters and competition for purchasing power the model distinguishes between two firm innovation strategies exploration and exploitation on the basis of a set of simulations of this model we derive a number of empirically testable hypotheses a subset of these have already found support in the empirical literature we take these as evidence in favor of the explanatory power of the model in addition we are able to derive further testable propositions on the interaction of firm demographic processes innovative behavior and market structure that go beyond the existing literature and that we suggest for further research we conclude that the approach chosen here provides a fruitful pathway for further research

pure strategy nash equilibria in an advertising game with interference abstract two manufacturers produce substitutable goods for a homogeneous market the advertising efforts of the two manufacturers determine the demand for the goods and interfere negatively with each other the demand of each good is a piecewise linear function of the product goodwill and the latter is a linear function of advertising efforts in a game with two competing profit maximizing manufacturers who have access to a set of several advertising media the pure strategy nash equilibria are characterized and their existence is shown

technological diversity of persistent innovators in japan two case studies of large japanese firms we have investigated two large japanese firms with their patent data technological histories and product sales data of over 30 years especially in terms of intra firm technology diversification and interactions between multiple technological trajectories patent data showed the process of emergencies of technological trajectories and interactions cross fertilization between them quantitatively both persistence and diversity of technology have contributed to product diversification and sales growth based on our findings we have demonstrated that taking advantage of economies of scope in technology through persistence and diversification is necessary for a technology based firm if it is to survive and to grow for a prolonged period of time 2003 elsevier b v all rights reserved

the state contingent properties of stochastic production functions this paper develops the state contingent properties of the most frequently used representations of stochastic production in the agricultural economics literature particular attention is paid to the cases of multiplicative and additive uncertainty and to the convolution of multiplicative and additive uncertainty embodied in the just pope stochastic production function state contingent technologies and their associated cost functions are reviewed and that theory is applied to the stochastic production function a generalisation of the just pope technology that has desirable state contingent characteristics is proposed cost functions based upon state contingent technologies are compared with cost functions based on a parametrised distribution representation of production uncertainty

cooperative advertising models in supply chain management a review this paper reviews articles on cooperative advertising a topic which has gained substantial interest in recent years thereby we first briefly distinguish five different definitions of cooperative advertising which can be found in operations research literature after that we concentrate on vertical cooperative advertising which is the most common object of investigation it is understood as a financial agreement where a manufacturer offers to pay a certain share of his retailer s advertising expenditures in total we identified 58 scientific papers considering mathematical modeling of vertical cooperative advertising these articles are then analyzed with regard to their general model setting e g the underlying supply chain structure and design of the cooperative advertising program after that we explain the different demand and cost functions that are employed whereupon we distinguish between static and dynamic models the last dimension of our review is dedicated to the game theoretic concepts which are mostly used to reflect different forms of distribution of power within the channel

sectoral systems of innovation and production the concept sectoral system of innovation and production provides a multidimensional integrated and dynamic view of sectors it is proposed that a sectoral system is a set of products and the set of agents carrying out market and non market interactions for the creation production and sale of those products a sectoral systems has a specific knowledge base technologies inputs and demand agents are individuals and organizations at various levels of aggregation they interact through processes of communication exchange co operation competition and command and these interactions are shaped by institutions a sectoral system undergoes change and transformation through the co evolution of its various elements 2002 elsevier science b v all rights reserved

estimates of marginal discovery costs for oil and gas previous estimates of the finding costs for oil and natural gas reserves have been impeded by the joint cost problem in exploration the solutions have been either to estimate the finding cost for an oil gas aggregate or to allocate total finding costs between oil discoveries and gas discoveries according to rules chosen by the researcher in this paper the joint cost problem is circumvented by estimating a multiple output exploration cost function which is used to calculate the predicted values of marginal finding costs for oil and gas these values are then compared with independent estimates of the shadow prices of reserves for oil and gas to help settle the debate over whether marginal finding costs provide a good measure of rent

the allocation of consumer incentives to meet simultaneous sales quotas an application to u s army recruiting consumer incentives often have a dual role to expand the market and to redistribute the market so as to meet sales targets for a range of products the proper allocation of incentives must recognize and deal with the competitive and cannibalizing effects operating among product classes the presence of environmental factors scale economies and cost per unit for each of the candidate incentive types also must be accounted for this paper develops and illustrates an analytical approach designed to improve the allocation of consumer incentives where sales targets are exogenously set the model generates a system of simultaneous behavioral equations a portion of which is included to reflect attempted cost minimizing behavior the model is applied to fy81 fy86 data from the u s army recruiting command which allocated over 1 billion for special incentives to selected recruits the incentives consist of enlistment bonuses and educational benefits offered to quality recruits who select critical occupational specialties the sales targets are enlistment quotas for each of the occupational specialties that must be simultaneously satisfied the army s goal is to meet these quotas in a postulated recruiting environment at minimum total incentive expenditure results suggest that the army could improve the cost effectiveness of its recruiting effort through a reallocation of the incentives it offers to recruits misallocation during the fy81 fy86 period is estimated to have cost the army approximately 3 5 of its total incentives expended in infantry recruiting recruiting

schumpeterian patterns of innovation are technology specific this paper examines the patterns of innovative activities at the technological and country levels using patent data for 49 technological classes in six countries usa japan germany france united kingdom and italy it is shown that the patterns of innovative activities differ systematically across technological classes but are remarkably similar across countries for each technological class in particular two groups of technological classes are identified schumpeter mark i and schumpeter mark ii in these two groups innovative activities are structured and organized in different ways the first represents a widening pattern concentration of innovative activities is low innovators are of small economic size stability in the ranking of innovators is low and entry of new innovators is high the second represents a deepening pattern concentration of innovative activities is higher than in the first group innovators are of larger economic size stability in the ranking of innovators is greater and entry is lower the former group comprises mechanical technologies and traditional sectors while the latter includes chemicals and electronics this result suggests that technology related factors such as technological regimes defined in terms of conditions of opportunity appropriability cumulativeness and properties of the knowledge base play a major role in determining the specific pattern of innovative activities of a technological class across countries within these constraints country specific factors introduce differences across countries in the pattern of innovative activities for a specific technological class finally the relationships between the specific features of the patterns of innovative activities and international technological specialization are examined technological advantages appear in general to be linked to higher degrees of asymmetries among innovators higher stability of the ranking of innovators smaller economic size of the innovating firms and lower entry rates of new innovators these relationships however are different in the two groups of technological classes in schumpeter mark i widening technological classes international technological specialization is associated with relatively higher degrees of asymmetries among innovators and entry of new innovators as well as smaller firm size while in schumpeter ii deepening technological classes international technological specialization is linked to the existence of a stable but competitive core of persistent innovators

comparative advertising disclosing horizontal match information improved consumer information about horizontal aspects of products of similar quality leads to better consumer matching but also to higher prices so consumer surplus can go up or down while profits rise with enough quality asymmetry though the higher quality and hence larger firm s price falls with more information so both effects benefit consumers this occurs when comparative advertising is used against a large firm by a small one comparative advertising as it imparts more information therefore helps consumers although it also improves the profitability of the small firm overall welfare goes down because of the large loss to the attacked firm

technology and public goods abstract this paper presents a theory of public goods based on production theory where public goods are viewed as inputs to the production process we examine the pure case of public inputs no private inputs as well as the mixed case private and public inputs we show how the case of public inputs is related to certain forms of nonjoint production and we characterize it in terms of variable profit and joint cost functions comparative statics results are derived graphically in the two by two case

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

sectoral patterns of technological activity and export market share dynamics this paper focuses on a selected number of oecd countries and manufacturing sectors and shows the importance of sectoral diversity in the innovative process and in the relation between technology and world market share dynamics the econometric exercise confirms the importance of technological variables in the relation with world market shares in two ways first they are in general statistically significant second the taxonomy of technological classes in terms of r d intensity seems to be meaningful in disentangling the role played by sectoral diversity in the relation between embodied and disembodied investment and competitiveness sectoral diversity emerges in the statistical significance of the coefficients and in the time lag structure moreover the values of estimated r d parameters are correlated with the sectoral r d intensity

technological regimes and sectoral patterns of innovative activities this paper focuses on the relationships between observed patterns of innovative activities within a sector and the related context and underlying microeconomic processes that might account for them it claims that there are some invariant features with respect to relative prices and incentives mechanisms of learning and knowledge accumulation that greatly affect the rate and structure of innovative activity these features are different across sectors the paper proposes that the specific pattern of innovative activity of a sector can be explained as the outcome of different technological regimes that are implied by the nature of technology and knowledge the notion of technological regime provides a synthetic representation of some of the most important economic properties of technologies and of the characteristics of the learning processes that are involved in innovative activities copyright 1997 by oxford university press

the relationship between firm growth and labor demand several american studies have recently estimated models of employment growth from longitudinal data sets of business firms evans 1987 leonard 1986 hall 1987 by and large these studies find that the growth rate of employment is inversely correlated with initial size measured by employment and with age young firms tend to grow more rapidly than old ones these studies have cast considerable doubt on gibrat s law or the assumption of independence between firm size and the rate of growth however departures from gibrat s law are modest especially among firms above minimum size recently a group of researchers has proceeded along similar lines of investigation using data from a panel of italian manufacturing firms located in northern italy the purpose of this paper is to compare our results with those obtained for the u s and to explore in more detail the soundness of this approach our results are similar to the abovementioned american studies we find that departures from gibrat s law are not large
