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

a large scale mapping of territorial development dynamics in latin america summary this paper summarizes a study of changes in per capita income monetary poverty and income distribution in 9 045 subnational administrative units of nine latin american countries between the mid 1990s and mid 2000s the results largely support spatial convergence of mean household incomes although the estimates indicate it has been slow territorial inequality is found to be persistent and reduces the pro poor effect of local income growth although national context specific the estimates also indicate that territorial development dynamics are influenced by the structural features of the territories in view of the evidence territorial development policies in latin america seem well warranted

buyer search costs and endogenous product design buyer search costs for price are changing in many markets through a model of buyer and seller behavior i consider the effects of changing search costs on prices both when product differentiation is fixed and when it is endogenously determined in equilibrium if firms cannot change product design lower buyer search costs for price lead to increased price competition however if product design is a decision variable lower search costs for price may also lead to higher product differentiation which decreases price competition in this case the overall effect of lower buyer search costs for price may even be higher prices lower social welfare and higher industry profits the result is especially interesting because recent technological changes such as internet shopping can affect the market structure through lowering buyer search costs

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

a percolation based model explaining delayed takeoff in new product diffusion a model of new product diffusion is proposed in which a site percolation dynamics represents socially driven diffusion of knowledge about the product s characteristics in a population of consumers a consumer buys the new product if her valuation of it formed after her witnessing the product in use among her friends or neighbors is not below the price of the product announced in a given period our model attributes the empirical finding of a delayed takeoff of a new product to a drift of the percolation dynamics from a nonpercolating regime to a percolating regime this drift is caused by learning effects lowering the price of the product or by network effects increasing its individual valuations by consumers both with an increasing number of buyers

grid connected renewable energy in china policies and institutions under gradualism developmentalism and socialism abstract this communication displays some of our on going research on the incompleteness of china s advances toward best practice in policy making and institution building for renewables in particular this paper 1 summarizes how chinese policies and institutions for the deployment of renewable electricity are only partially compliant with what is internationally recognized as best practice and 2 contextualizes chinese policies and institutions for renewables in the broader picture of china s political economy much as a political economy perspective has aided the understanding of why chinese economic reforms were partial and unique the said contextualization might help explain why china s policies and institutions for renewables diverge from best practice further given that china proved successful in promoting its economic growth with partial and unique reforms the partiality and uniqueness of its renewables policies and institutions need not impede the rapid development of renewable electricity this on going research has so far combined a review of specialized literature and the business press with semi structured interviews held with relevant actors in policy business and research related to renewable energies

search costs and investment in quality in this paper we analyze how lower search costs aect rms incentives to invest in quality we identify two con icting eects on the one hand lower search costs increase incentives to invest in quality by eroding the market share of low quality rms and increasing the market share of high quality rms on the other hand by intensifying price competition lower search costs adversely aect high quality rms more than low quality rms the net eect of a change in the search cost on quality is shown to depend on the initial quality distribution there is a critical value such that if the average quality in the market is initially above this value lower search costs lead to lower quality whereas if the initial quality is below this value lower search cost leads to higher quality we show that our results are consistent with a superstar eect

demand and innovation schmookler re examined schmookler s demand pull hypothesis implying that innovation is a function of market demand has been widely accepted re reading schmookler s invention and economic growth we discover a statistical inadequacy re estimating his cross section results in a different way we find somewhat lower coefficients moreover the direction of causality appears to be far from obvious an independent cross sectional test of the schmookler hypothesis in the netherlands based on r d instead of patent data shows similar results the relationship between indicators of demand and innovation turns out to be generally weaker but in most cases still significant and the results suggest that there is a simultaneous relationship between demand and innovation the latter may be explained by the concept of the innovation multiplier which has implications for macro economic modelling 1 re reading schmookler schmookler s 13 finding of a strong relationship between investment in capital goods users industries and patent applications by capital goods producing sectors has been generally accepted by economists as evidence that patenting is a function of effective demand demand pull hypothesis quite a number of case studies have followed schmookier s seminal work but there have been

incentives and uncertainty an empirical analysis of the impact of demand on innovation we study the impact of demand on innovation by focusing on a sample of small and medium sized enterprises in several industries and european countries we analyse how demand stimulates innovation by providing economic incentives and reducing uncertainty considering the size of the market as a proxy for the presence of demand we find support for the idea that the presence of incentives stimulates innovation this is particularly true for process innovation in considering interaction with customers as a way to reduce uncertainty we find that firms that see customers as the most important sources of information for both innovation ideas and completion tend to introduce product innovations firm size r d expenditure and sectoral effects also matter

wind power policy in complex adaptive markets abstract this paper aims to advance research into the effectiveness of policies for encouraging technological transition in the energy sector in general and wind power in particular it contends that the ineffectiveness of wind power development policy in most nations stems from a linear approach to policy design that is unsuited to complex adaptive markets the paper argues that in complex adaptive markets policies are required that foster competition on a level playing field insights are extracted from complexity theory to advance four principles for effective wind power policy in such markets these principles include establishing policy initiatives to encourage technological diversity establish clear and progressive short to medium term targets enhance environmental monitoring systems and establish a malleable policy regime that directly resolves emergent challenges while simultaneously sustaining market momentum to ensure long term targets are met in order to demonstrate the applied relevance of these principles the paper applies these concepts to a historical analysis of denmark s wind power development policies

the effectiveness of china s wind power policy an empirical analysis abstract along with china s rapid industrialization and urbanization challenges in reducing pollution and co 2 emissions are increasing one of the major approaches to coordinate economic growth and environmental protection is to substitute coal fired power with renewable energy since 2003 in order to promote wind power development china has put in place many support policies which fall into either price policy category or non price policy category by using a variable intercept and mixed regression model with provincial panel data during 2001 2013 we analyzed the impacts of both categories on the increase of installed capacity in areas with different wind resources we found that price policy and two non price policies had positive impacts on the increase of wind power installation price policy played a greater role than non price policy did in promoting wind power development and price policy was more effective in areas with poor wind resources whilst non price policy was more effective in areas with rich wind resources built on these findings conclusions and policy recommendations are provided at the end of the paper

hedonic price indexes for spreadsheets and an empirical test for network externalities in this article i first estimate hedonic price equations for computer spreadsheet programs and then use the analysis to empirically test whether network externalities exist in this industry the study shows that consumers are willing to pay a significant premium for spreadsheets that are compatible with the lotus platform and for spreadsheets that offer links to external databases and a similar premium for spreadsheets that offer local area network externalities finally the quality adjusted real price of computer spreadsheets declined by approximately 15 per year from 1986 to 1991

modelling r d expenditure data with zero observations two equation model this article attempts to analyse the determinants of firms research and development r d expenditures in korea by considering the business environment after the economic crisis in 1997 in addition to take into account zero r d expenditure this article employed a two equation model unlike models used in other studies this method incorporates a two level decision structure the participation decision and the decision on the amount to spend once the issue of participation has been decided according to the estimation results while the proposition that larger firms are more active in r d is true the proposition that firms that possess market power are more active in r d is not true for korea technical cooperation among korean firms seems to be less active than in other countries in addition the results indicate that foreign investment stimulates the firms r d expenditure furthermore a number of factors were found to play a role in promoting firms r d activities the external conditions of the f

dynamic competition with network externalities why history matters we consider dynamic competition among platforms in a market with network exter nalities a platform that dominated the market in the previous period becomes focal in the current period in that agents play the equilibrium in which they adopt the focal platform whenever such equilibrium exists yet when faced with higher quality competition can a low quality platform remain focal in the finite horizon case the unique equilibrium is efficient for patient platforms with an infinite time horizon however there are multiple equilibria where either the lowor high quality platform dominates if qualities are stochastic the platform with a better average quality wins with a higher probability even when its realized quality is lower and this probability increases as platforms become more patient hence social welfare may decline as platforms become more forward looking

privatization in eastern europe irreversibility and critical mass effects abstract this paper proposes a model to shed light on two important policy features of privatization in central and eastern europe the idea of a necessary critical mass of privatization on one hand and the great difficulties encountered in the actual privatization process on the other the model incorporates a positive externality related to the size of the private sector multiple equilibria may arise for political and economic reasons policies of free distribution are analysed with the model they may eliminate the danger of policy reversals due to excess unemployment but may at the same time increase the relative cost of restructuring leading in some cases to pareto inferior outcomes

danish and norwegian wind industry the relationship between policy instruments innovation and diffusion this article compares the role of policy instruments in stimulating long term technological change in danish and norwegian wind industry it concludes that although predictability has periodically been low denmark s broad portfolio of policies and measures has been well adapted to the different stages in the development of its wind industry this has contributed to a high degree of innovation successful establishment in niche markets high degree of diffusion and establishment of domestic and international mass markets and in recent years an increasingly successful replacement of senescent technology with new the motivation of norway s wind energy policies and measures at least up until the late 1990s has been to increase power supply rather than to stimulate industrial development and technological change policies and measures have been weaker than in denmark have been less stable over time and stimulated the demand side much less they have not sufficiently covered the wind industry s perceived needs on different stages in the development of new technology and have not sufficiently stimulated continuous improvement learning and new product development dynamic efficiency in industry this has been part of the reason why there has been only a limited extent of innovation and diffusion of wind technology in norway

sectoral patterns of technical change towards a taxonomy and a theory abstract the purpose of the paper is to describe and explain sectoral patterns of technical change as revealed by data on about 2000 significant innovations in britain since 1945 most technological knowledge turns out not to be information that is generally applicable and easily reproducible but specific to firms and applications cumulative in development and varied amongst sectors in source and direction innovating firms principally in electronics and chemicals are relatively big and they develop innovations over a wide range of specific product groups within their principal sector but relatively few outside firms principally in mechanical and instrument engineering are relatively small and specialised and they exist in symbiosis with large firms in scale intensive sectors like metal manufacture and vehicles who make a significant contribution to their own process technology in textile firms on the other hand most process innovations come from suppliers these characteristics and variations can be classified in a three part taxonomy based on firms 1 supplier dominated 2 production intensive 3 science based they can be explained by sources of technology requirements of users and possibilities for appropriation this explanation has implications for our understanding of the sources and directions of technical change firms diversification behaviour the dynamic relationship between technology and industrial structure and the formation of technological skills and advantages at the level of the firm the region and the country

competing technologies the learning curve and rational expectations abstract the problem of choice between several variants of a technology subject to dynamic learning economies is examined in a rational expectations model with overlapping adopters it is shown that even with rational expectations the long term market outcome depends sensitively on the pattern of early chance events and that only one variant of the technology will come to dominate the market in the long run this variant need not be the one which is socially optimal or most promising technically

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

firm size small business presence and sales of innovative products a micro econometric analysis in our generalized tobit analysis we identify a number of variables which have an impact on a firm s innovation output among others we find that larger firms generally have a higher probability of selling some innovative products although this probability increases less than proportionately with firm size given that a firm has some sales of innovative products the share of such products in a firm s total sales tends to be higher in smaller firms moreover a strong small business presence in a sector seems to enhance imitative innovation but has no influence on true innovations whereas market concentration has no influence on innovation output in whatever definition we also find evidence of regional knowledge spill overs furthermore our results are consistent with schmookler s hypothesis that the growth of demand enhances innovation the outcomes about the impact of r d collaboration and technology transfer on innovation remain ambiguous

danish energy reform policy implications for renewables abstract for decades renewables have been promoted in denmark by the feed in model fixed price scheme with favourable tariffs for green electricity this has resulted in successful penetration of wind power covering more than 13 of danish electricity consumption 2001 changing the promotional scheme to a quota based system with tradable green certificates has been on the political agenda since 1999 this article discusses danish energy policy with focus on the implications for the penetration and deployment of renewables it has turned out to be more complicated than anticipated to create an efficient operational system for trade in green certificates and the starting date for trading has been postponed several times the national green certificates market was to be fully operational by the beginning of 2003 however political negotiations in the fall of 2001 seem to postpone the initiation of the certificate market until 2005 transitional rules for green electricity during the period from 2003 to 2005 are under negotiation after a national election in november 2001 this situation has created widespread uncertainty among potential investors in green electricity the article evaluates a number of problems related to the shift in danish energy policy

platform selection in the lab abstract emerging literature explores experimental platform selection games these games converge rapidly on the superior platform under a wide range of conditions we replicate the remarkable results of hossain and morgan 2009 in which such a game tips almost perfectly to the superior platform next we show that platform coordination fails when seemingly innocent increases in out of equilibrium payoffs are introduced the inflated payoffs keep the best reply structure unchanged and do not influence players security levels our design allows control for the explanatory force of risk dominance we find that equilibrium selection theory is unable to account for coordination failure while observed behavior is consistent with non rational learning furthermore and contrary to the literature we find that efficiency suffers when an inferior platform is granted initial monopoly

market versus corporate structure in plant level innovation performance this paper examines the effect which market and corporate structure have on the extent of innovation for a sample of circa 300 manufacturing plants located in scotland innovation is defined as the introduction of a commercially significant new product at the establishment level the theoretical model of geroski 1990 is extended to incorporate plant level variables such as size multiplant operation the presence of r d facilities and external indigenous ownership a distinction is made between the direct and indirect effects of these variables negative binomial estimations indicate that corporate structure influences are more important in determining the number of innovations than market structure and barrier to entry variables plant size foreign ownership and the presence of r d are all positively associated with innovation direct effects greatly outweigh indirect effects tobit estimations on the number of innovations per employee support the findings of acs and audretsch 1988 that smaller enterprises are more innovation intensive than larger enterprises at least up to a limit of around 1200 employees the positive effect of r d arises principally from increasing the probability of a plant becoming an innovator rather than from making a plant more innovation intensive by contrast the importance of size lies principally in encouraging further innovations among plants which are already innovators but less than proportionately with the increase in employment size

biodiversity conservation in a dynamic world may lead to inefficiencies due to lock in effects and path dependence abstract although biodiversity is generally diminishing in some areas its conservation is expanding however the exact path of this expansion is uncertain this can lead to problems of path dependence and lock in effects path dependence describes situations where history strongly influences present decisions and lock in effects refer to situations where an earlier decision provides strong incentives to follow a particular path even if more efficient alternatives are available later on we develop a conceptual ecological economic model to investigate which ecological and economic parameters favour the appearance of efficiency losses in biodiversity conservation due to path dependence and lock in effects in a dynamic two period two region model generally we find that efficiency losses occur if there are signals that guide the first period budget into a region that later turns out to be suboptimal if both time periods had been considered right from the beginning to illustrate the conservation relevance of our findings we present potential efficiency losses through path dependence in the hypothetical case of applying offsets to conserving the endangered maculinea teleius butterfly near the city of landau in germany

competition and the incentive to produce high quality previous literature indicates that when quality is a choice variable firms have an incentive to produce high quality to maintain their reputations with consumers the strategic interaction among firms and competition for market share is not considered this paper finds that when firms compete for market share perfect equilibria in which firms produce high quality goods need not exist competition for customers can eliminate the price premium needed to induce firms to maintain a reputation for high quality production in this case economists and policy analysts should pay greater attention to the interaction among firms and the institutions such as professional associations that structure interfirm relations when considering whether firms have an incentive to produce high quality goods

property rights and the role of the state evidence from the horn of africa this study applies extant theories of property rights change to three land tenure systems in imperial ethiopia two of the areas underwent changes in property rights after experiencing changes in the value of land one did not a data set of litigation over land rights is used in conjunction with case studies to understand the mechanisms motivating or impeding property rights change amendments to the role of the state are suggested and two conclusions are reached 1 that movement towards greater specificity of land rights did not always occur and 2 the changes in property rights that occurred were imposed from above rather than occurring endogenously where property rights changes did not occur they appear to have been blocked by the state which was more concerned with political survival than with revenue maximisation

reputation and competition this paper shows how competition generates reputation building behavior in repeated interactions when the product quality observed by consumers is a noisy signal of firms effort level there are two types of firms and good firms try to distinguish themselves from bad firms although consumers get convinced that firms which are repeatedly successful in providing high quality are good firms competition endogenously generates the outside option inducing disappointed consumers to leave firms this threat of exit induces good firms to choose high effort allowing good reputations to be valuable but its uncompromising execution forces good firms out of the market jel c7 d8

is demand pulled innovation equally important in different groups of firms previous empirical literature has tested the demand pull hypothesis and found that innovation may be driven by output using a balanced panel of 216 italian manufacturing firms 1995 2000 and checking for the path dependent nature of r d we find a role of sales in inducing r d however the demand pull effect plays a varying role for different sub samples of firms exporting firms liquidity constrained firms not subsidised firms and those not heading a group seem to be sensitive to sales in deciding r d these results have been obtained using a least squares dummy variable corrected estimator a recent panel data technique suitable for small samples

adaptation as information restriction the hot stove effect individuals and social systems are often portrayed as risk averse and resistant to change such propensities are characteristically attributed to individual organizational and cultural traits such as risk aversion uncertainty avoidance discounting and an unwillingness to change this paper explores an alternative interpretation of such phenomena we show how the reproduction of successful actions inherent in adaptive processes such as learning and competitive selection and reproduction results in a bias against alternatives that initially may appear to be worse than they actually are in particular learning and selection are biased against both risky and novel alternatives because the biases are products of the tendency to reproduce success that is inherent in the sequential sampling of adaptation they are reduced whenever the reproduction of success is attenuated in particular when adaptation is slowed made imprecise or recalled less reliably the propensity to engage in risky and new activities is increased these protections against the error of rejecting potentially good alternatives on inadequate experiential evidence are costly however they increase the likelihood of persisting with alternatives that are poor in the long run as well as in the short run

managerial incentives and product market competition are imperfectly competitive leibenstein 1966 claims that there may be a substantial amount of x inefficiency where x inefficiency measures the degree to which actual profits depart from the maximum of profits that could be obtained if all operations in the firm were carried out at minimal costs he offers empirical evidence from case studies showing that the welfare loss due to organizational slack is of an order of magnitude bigger than the welfare loss due to monopolistic price distortions on imperfectly competitive markets these results support the common presumption that increasing competition reduces organizational and in particular managerial slack however this early literature does not offer a theoretical explanation for the link between competition and managerial incentives in particular it ignores the fact that managerial incentives can be affected by the design of an incentive scheme in this paper i derive the optimal incentive scheme for a manager as a function of the competitiveness of the environment in which his firm operates the basic impact of increased competition is that it reduces the profits of a firm this has two effects in the model first if a firm has high costs then the reduction of profits may be sufficient to render the firm unprofitable so the probability that it has to be liquidated goes up this unambiguously induces the manager of the firm to work harder for a cost reduction in order to avoid liquidation and to keep his job second the reduction in profits may affect

imperfect competition and reputational commitment abstract competition can both aid and hinder reputational commitments for quality these are self sustaining depending on future profits after maintaining or deviating from the commitment and on current costs of sustaining it competition can affect these three elements at different rates

invention and innovation in the chemical industry demand pull or discovery push abstract this paper describes a study of the determinants of the rate direction and scale of inventive and innovative activity in the chemical industry over the period 1830 1980 statistical data are interpreted in the light of case study material in three major sectors dyestuffs plastics and pharmaceuticals theories of technical change and economic growth particularly those of schmookler and schmpeter are examined in relation to this material on the chemical industry the findings suggest that the importance of demand pull and discovery push factors and the validity of schmookler s and schumpeter s theories vary over an industry s life cycle

the socio political economy of electricity generation in china abstract in addition to providing a review of electricity generation developments in china this paper features the development of a framework for understanding the socio political economy influencing electricity market development it documents and presents a critical evaluation of the social technological economic and political forces which influence electricity generation policy in china the analysis provides insight into why china s electricity generation shopping basket is being filled with both coal and co2 reduced electricity generation technologies it concludes that installed capacity of hydro power wind power nuclear power and solar pv power will outpace government projections due to inter alia a proclivity on the part of the chinese government to set conservative and achievable targets waning apathy toward pollution associated with coal fired power progressive improvements in grid connection and resilience increased economic viability of these alternative energy sources and government support for these industries as strategic commercial sectors

pricing product diversity and search costs a bertrand chamberlin diamond model we study price competition in the presence of search costs and product differentiation the limit cases of the model are the bertrand paradox the diamond paradox and chamberlinian monopolistic competition market prices rise with search costs and decrease with the number of firms prices may initially fall with the degree of product differentiation because more diversity leads to more search and more competition equilibrium diversity rises with search costs while the optimum level falls so entry is excessive the market failure is most pronounced for low preference for variety and high search costs

determinants of environmental innovation new evidence from german panel data sources abstract in most cases empirical analyses of environmental innovations based on firm level data relied on surveys for one point in time these surveys allow for the inclusion of many explanatory variables such as different policy instruments or the influence of pressure groups but it is not possible to address the dynamic character of environmental innovations this paper uses two german panel databases the establishment panel of the institute for employment research iab and the mannheim innovation panel mip of the centre for european economic research zew to explore the determinants of environmental innovations the econometric estimations show that the improvement of the technological capabilities knowledge capital by r d triggers environmental innovations environmental regulation environmental management tools and general organizational changes also encourage environmental innovation a result that has also been postulated by the famous porter hypothesis

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

recent results in measuring innovation output abstract the fraunhofer institut fur systemtechnik und innovationsforschung isi is at present engaged in evaluating a number of technology policy programs designed to promote research development and innovation in small and medium sized firms these studies try to determine the extent to which these programmes have an impact upon the innovative activities of firms in this connection it was also attempted to measure the innovation output the level of innovation of a firm is innovation ouput the level of innovation of a firm is procedure involves a number of problems self assessment of firms in view of insufficient market transparency distortion due to self portraits reflecting the firms own interests we tried to mitigate such distortions by two approaches firstly firms were asked for their technologically new products the term new being applied a to the firm and b to the areas of product application as a result of this two tier procedure firms supplied rather realistic answers secondly supplementary questions were asked about sales figures the competitive technological situation nationally and internationally expenditure on r d patents stages of innovation aims of innovation etc the paper presents the results obtained to date on the innovation output of firms within the framework of an evaluation of the largest programme at present devoted to promoting r d and innovation in small and medium sized firms the results are based on a representative sample of approximately 4 500 small and medium sized firms up to 1 00 employees with r d activities in the federal republic of germany

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

incentive regulation of electricity distribution networks lessons of experience from britain this paper reviews the recent experience of the uk electricity distribution sector under incentive regulation the uk has a significant and transparent history in implementing incentive regulation in the period since 1990 we demonstrate the successes of this period in reducing costs prices and energy losses while maintaining quality of service we also draw out the lessons for other countries in implementing distribution sector reform we conclude by discussing the place of incentive regulation of networks within the wider reform context the required legislative framework the need for appropriate unbundling the importance of quality of service incentives the regulatory information requirements and the role of sector rationalisation

demand dynamics with socially evolving preferences in this work we first identify a few stylized facts concerning microconsumption acts second building on them we develop a simple model of boundedly rational consumers who endogenously evolve their preferences via both innovation and social imitation third we explore some statistical properties of the demand patterns generated by the model which despite its simplicity are surprisingly in line with the empirical evidence these results we suggest bring encouraging support to microfoundations of demand theory based on cognitive and behavioral foundations more in tune with the psychological and sociological evidence based on heterogeneous agents who are much less rational and much more social than in standard theory and who collectively discover along the way what they like within a growing universe of available commodities

search design and market structure the internet has made consumer search easier with consequences for prices industry structure and the kinds of products oered we explore these conse quences in a rich but tractable model that allows for strategic design choices a polarized market structure results where some rms choose designs aimed at broad based audiences while others target narrow niches such an industry structure can arise even when all rms and consumers are ex ante identical we analyze the eect of reduced search costs and nd results consistent with the reported prevalence of niche goods and the long tail and superstar phe nomena in particular the model suggests that long tail eects arise when there is a wide range of potential designs relative to vertical heterogeneity among rms

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

firms motivations for cooperative r d an empirical analysis of spanish firms abstract the aim of this paper is to analyze the motives that have caused industrial firms to cooperate in r d there are many theoretical works devoted to the theme but few empirical studies have been carried out with large samples to analyze the factors which determine why firms cooperate in r d we first review the reasons offered by the literature to explain technological cooperation with this allowing us to determine the conceptual framework and to propose some hypotheses we test these hypotheses with a sample of 1652 spanish firms that have carried out r d activities the results obtained suggest that firms motivations for cooperative r d are the complexity of technology and the fact that innovation is costly and uncertain we find that in order to undertake cooperative r d it is necessary to have certain internal capacities in this area with our results being supported by the theory of absorptive capacity however and by contrast with the results presented in other works questions related to market access and search for opportunities do not appear to exert an influence over cooperative r d besides the large sized firms resort more to cooperation and the reasons for cooperative r d differ as between large and small sized firms

the economics of convention c onventions regulate much of economic and social life yet they have received surprisingly little attention from economists by a convention we mean a pattern of behavior that is customary expected and self enforcing everyone conforms everyone expects others to conform and everyone has good reason to conform because conforming is in each person s best interest when everyone else plans to conform lewis 1969 familiar examples include following rules of the road adhering to conventional codes of dress and using words with their conventional meanings conventions with direct economic implications include species of money and credit industrial and technological standards accounting rules and forms of economic contracts indeed it would scarcely be an exaggeration to say that almost all economic and social institutions are governed to some extent by convention the main feature of a convention is that out of a host of conceivable choices only one is actually used this fact also explains why conventions are needed they resolve problems of indeterminacy in interactions that have multiple equilibria indeed from a formal point of view we may define a convention as an equilibrium that everyone expects in interactions that have more than one equilibrium the economic significance of conventions is that they reduce transaction costs imagine the inconvenience if whenever two vehicles approached one another the important exceptions are sugden 1986 and ullman margalit 1977 the interested reader might also refer to the symposium on social norms that appeared in the fall 1989 issue of this journal with articles by sugden 1989 and elster 1989

wind electricity in denmark a survey of policies their effectiveness and factors motivating their introduction this paper surveys the development of the policies supporting the introduction of wind electricity in denmark in the last 15 years with special attention to the new policy introduced after a 2 year long debate the aim of this paper is to explore the roles of financial support policy certainty and planning constraints in the diffusion of wind electricity in denmark and the reasons prompting the change of the system in the current decade it is discovered that political uncertainty has badly affected the effectiveness of the feed in law in the years immediately after its introduction with regard to the new system it is concluded that the change has been prompted by generous conditions under the feed in law and by the desire to facilitate the modernisation of old turbines it is also concluded that incentive based systems can be more effective than tradable quotas in promoting the modernisation of renewable plants this finding is relevant to the development of energy policy in countries such as germany and spain where the average age of wind turbines is much younger than those existing in denmark

the two faces of market support how deployment policies affect technological exploration and exploitation in the solar photovoltaic industry the recent years have seen a strong rise in policies aiming to increase the diffusion of clean energy technologies while there is general agreement that such deployment policies have been very effective in bringing technologies to the market it is less understood how these policies affect technological innovation to shed more light on this important question we conducted comparative case studies with a global sample of 9 firms producing solar photovoltaic pv modules complemented by in depth interviews with 16 leading pv industry experts we propose that on the one hand policy induced market growth serves as an important catalyst for innovative activity as it raises the absolute level of firm investments in technological exploration on the other hand however deployment policies create an incentive for firms pursuing more mature technologies to shift their balance between exploitation and exploration toward exploitation firms focusing on less mature technologies cannot tap the potentials of exploitative learning to the same extent as those with more mature technologies therefore stimulating strong market growth may raise the barrier to market entry for less mature technologies we conclude that when designing deployment policies great care should be taken to avoid adverse effects on technological diversity and a premature lock in into more established technologies

bad eggs learning by doing and the choice of technology we model long run economic development through technology adoption under scientific uncertainty about environmental effects there are four possible long run equilibria in a socially planned economy high growth adopt rapidly but abandon damaging technologies once revealed ddt cfcs cautious brake the introduction of new technologies to avoid mistakes genetically modified organisms no growth halt technological progress to preserve secondary knowledge and collapse adopt rapidly without ever abandoning damaging technologies in the base parameterization a short sighted social planner chooses the cautious strategy a far sighted planner chooses the high growth strategy unless damages are irreversible in which case the cautious strategy again dominates regulatory options in the market economy are investigated pollution taxes do not affect the firm s level of precaution if they can only be applied after the adopting firm has reaped the benefits however they do encourage the abandonment of damaging technologies liability rules do affect precaution but may lead to excessive caution or even a no growth trap

innovative activity over the business cycle this paper examines cyclical patterns of innovative activity in the united kingdom over the period 1948 83 innovative activity turns out to have many of the properties of a random walk but does show a tendency to cluster during booms there is clear evidence of a long term secular relation between the level of innovative activity and the level of economic activity although this may have changed in the 1980s finally the data provide no reason for thinking that these clusters of innovation cause cyclic variations in economic activity but variations in economic activity do granger cause changes in innovative activity copyright 1995 by royal economic society

true monopolistic competition as a result of imperfect information the paper restates hart s 1985a 1985b definition of large group monopolistic competition distinguishes it from oligopolistic competition and raises the question of whether there are reasonable circumstances that give rise to true monopolistic competition as defined the purpose is to show that consumers imperfect information may create conditions that will turn an otherwise oligopolistic market into a truly monopolistically competitive one
