regulatory reform in britain regulatory reform in britain john kay and john vickers major sectors of the british economy are currently undergoing far reaching regulatory reform deregulation removal of barriers to competition and the introduction of new methods of regulation are occurring notably in financial services some of the professions and in utility industries such as telecommunications gas and electricity this paper gives an economic assessment of these developments the authors examine the root causes of market failure that call for regulation externalities monopoly and information problems and the pros and cons of various regulatory responses a broad distinction is drawn between structural regulation the determination of which firms or types of firms can engage in which activities and conduct regulation the control of how firms behave in their chosen activities recent examples of deregulation plus re regulation in britain are seen in part as a shift from structural to conduct regulation the relative merits of the two modes of regulation are complex to assess but it is argued that some recent regulatory reforms are placing undue reliance on conduct regulation as well as assessing individual industries the authors draw general conclusions about the desirability of regulatory solutions that make full use of market forces

network externalities technological progress and the competition of market contracts abstract network externalities are used to describe the fact that many modern products become more valuable the more users adopt products of the same technology where network externalities and technological progress exist the various kinds of inefficiencies discussed in the recent literature can be explained by different types of contracts the main categories analysed are simple market contracts update contracts and service contracts it is shown that these types of contract emerge endogenously from the incentive structure of profit maximizing firms competition between these contracts may substantially reduce inefficient allocations caused by network externalities

competition and social influence the diffusion of the sixth generation processor in the global computer industry1 when is a social actor most strongly influenced by its peers this article addresses this question by clarifying when computer firms were most strongly affected by the choices of their structurally equivalent rivals to adopt a well known technology intel s sixth generation processor the core hypothesis is that the effect of adoptions by structurally equivalent firms increases with the competitive pressure that a focal firm faces in its market position the results show that a chosen firm is most strongly influenced by comparable others when it faces scale based competition and is diversified the implications of this study are twofold a social actor s sensitivity to the conduct of others may depend not only on its place in a hierarchy but also on the nature of its ties to an external audience and a contingent theory of social influence may be necessary to characterize diffusion processes correctly particularly when external and time varying nonnetwork factors have significant effects

tying and innovation a dynamic analysis of tying arrangements this paper analyses the effects of tying arrangements on r d incentives it shows that tying is a means through which a firm can commit to more aggressive r d investment in the tied goods market tying also has the strategic effect of reducing rivals incentives to invest in r d the strategy of tying is a profitable one if the gains via an increased share of dynamic rents in the tied goods market exceed the losses that result from intensified price competition in the market the welfare implications of tying and consequently the appropriate antitrust policy are discussed

the eu 2020 innovation indicator a step forward in measuring innovation outputs and outcomes in october 2013 the european commission presented a new indicator intended to capture innovation outputs and outcomes and thereby support policy makers in establishing new or reinforced actions to remove bottlenecks that prevent innovators from translating ideas into products and services that can be successful on the market this article aims to evaluate the usefulness of the new indicator against the background of the difficulties in measuring innovation outputs and outcomes we develop a unique conceptual framework for measuring innovation outcomes that distinguishes structural change and structural upgrading as two key dimensions in both manufacturing and services we conclude that the new indicator is biased towards a somewhat narrowly defined high tech understanding of innovation outcomes we illustrate our framework proposing a broader set of outcome indicators capturing also structural upgrading we find that the results for the modified indicator differ substantially for a number of countries with potentially wide ranging consequences for innovation and industrial policies

breakthrough china s and india s transition from production to innovation summary china and india have become major producers of products and services for global markets this article explores to what extent they are also building up innovation capabilities it draws on a combination of approaches innovation systems global value chains and professional networks to analyze four of the most dynamic industries we find that mounting innovation efforts only rarely materialized in cutting edge innovations but suggest that if capital accumulation proceeds at the current pace innovation capabilities will rapidly be built up in china and with a time lag india we conclude by setting out the implications for both the developed and the developing world

build or buy strategies in the local loop we provide a dynamic model to study how the presence of the option to buy the incumbent local exchange carrier s ilec facilities via local loop unbundling affects the competitive local exchange carriers clecs incentives to build alternative infrastructures we show that an unregulated incumbent sets a rental path for its local loop which delays technology adoption compared to the case in which there is no unbundling we also characterize the equilibrium rental path set by the unregulated incumbent it is prohibitively high at the initial phases when there is no effective threat of entry with alternative technologies and it is decreasing over time in later phases the decrease in the rental price follows the rise of the entrant s opportunity cost of leasing lines we also argue that neither allowing higher prices for unbundled elements over time nor setting a sunset clause would suffice to induce facility based competition by studying the unregulated ilecs decision regarding unbundling we challenge the implicit assumption behind the sunset clauses which is that the ilec would either deny unbundling or charge too high a price for its network elements in the absence of regulation we claim that the ilecs that initially resist unbundling requirements would tend to charge attractive access prices relative to the entrants alternatives for their infrastructure which become less essential over time this abstract was borrowed from another version of this item

promoting network competition by regulating termination charges abstract this paper contributes to the policy debate about the optimal termination charge when penetration rates are explicitly taken into account although lowering termination charges towards cost leads to more efficient usage its impact on consumer surplus is ambiguous since it induces an increase in fixed subscription fee through the so called waterbed effect we show that a reduction in termination charge below cost has two opposing effects on consumer surplus it softens competition but also helps to internalize network externalities hence it can decrease or increase penetration depending on whether or not the first effect dominates the second we show that the first effect dominates the second when networks are weak substitutes or the penetration rate is high

policies and international trade agreements on technical compatibility for industries with network externalities abstract the paper considers a country home in which consumers have heterogeneous preferences over ex ante incompatible domestic and imported products and benefit from a network externality we analyze the cases with trade under perfect competition and the international duopoly in which both governments strategically use policies toward compatibility but cannot use conventional trade policies in both cases the equilibrium outcome of the non cooperative game depends upon the strength of the network externality effect and involves either an excessively high equilibrium level of compatibility in combination with either too much or too little trade or very low equilibrium levels of both compatibility and trade the paper concludes with the analysis of the international agreements on policies toward compatibility and evaluates the existing provisions in the wto legal system aimed at minimizing the trade inhibiting impact of standards and regulations in the area of technical compatibility

managing technological development lessons from the newly industrializing countries this survey looks at the technological development of the newly industrializing countries to draw some important lessons for firms and governments in other developing countries first inventing products and processes is not at the center of the technological development needed for successful industrialization it is at the fringe what is at the center is acquiring the capabilities needed for efficient production and investment second some countries have overemphasized the drive for technological self sufficiency and paid a high price in poor productivity what makes the best economic sense is to combine foreign and local technological elements and to do this in a way that progressively develops local capabilities in areas where they can be more efficient third the acquisition of technological capability does not come merely from experience though experience is important fourth the economic environment through its influence on the technological efforts of firms is very important in determining the productivity of a country s resources

tools of the trade the socio technology of arbitrage in a wall street trading room to analyze the organization of trading in the era of quantitative finance we conduct an ethnography of arbitrage the trading strategy that best exemplifies finance in the wake of the quantitative revolution in contrast to value and momentum investing we argue arbitrage involves an art of association the construction of comparability across different assets in place of essential or relational characteristics the peculiar valuation that takes place in arbitrage is based on an operation that makes something the measure of something else associating securities to each other the process of recognizing opportunities and the practices of making novel associations are shaped by the specific socio spatial and socio technical configurations of the trading room calculation is distributed across persons and instruments as the trading room organizes interaction among diverse principles of valuation

optimal bundling of technological products with network externality for many high tech and internet related products utility to consumers depends in part on the size of the user base a phenomenon called network externality a firm with a portfolio of these and other products that are often asymmetric in their degree of network externality or marginal cost may have to look beyond the traditional strategies of pure components pure bundling and mixed bundling one such strategic alternative in a two product case would be a so called mixed bundling 1 under which the bundle and product 1 are offered but the other product can only be purchased in a bundled form the purpose of this study is to compare and contrast the impact of such asymmetry or symmetry in direct network externality and cost on the choice of bundling strategies we model a monopolist firm that has a product in each of two categories and faces heterogeneous consumers results suggest that pure bundling is more profitable when both products have low marginal costs or high network externality whereas pure components or mixed bundling 1 is more profitable when the products diverge in their costs and network externality e g only one product has network externality traditional mixed bundling is optimal in other instances

corruption federalism and policy formation in the oecd the case of energy policy we investigate whether the effect of government corruption is conditional on a country s institutional structure federal systems have an additional layer of government making lobbying relatively more costly we investigate whether the effect of government corruption on environmental policy in the form of restrictions on energy use is conditional on a federal system being in place using 1982 96 data from 11 industry sectors in 12 oecd economies we find that while greater government corruption reduces the stringency of environmental policy the effect declines in federal systems

environmental policies and innovation a knowledge based perspective on cooperative approaches the purpose of this article is to analyse to growing interest in the field of the environment for new cooperative approcahes that make use of negotiated instruments such as voluntary agreements using an interpretation framework that puts the emphasis on collective learning and monitoring devices we highlight the value of this type of approach in situations of great uncertainty where a coordinated process of innovation is required to achieve ambitious environmental targets the implementation of this theoretical approach in the end of life vehicles elv case which has been the subject of several voluntary agreements in europe offers a fuller understanding of the characteristics and driving forces of the collective innovation process in action as well as the obstacles that have still to be overcome in particular we explain why monitoring of innovation by the authorities focusing on coordination mechanisms is a crucial issue on which further research should be carried out

stimulating different types of eco innovation in the uk government policies and firm motivations in this paper we adopt a recent oecd framework and examine the role of external policy tools and internal firm specific factors for stimulating three different types of eco innovations that range on a spectrum of lower to higher technological and environmental impacts end of pipeline pollution control technologies integrated cleaner production technologies and environmental r d using a novel firm level dataset from a defra survey we estimate a tobit model which provides empirical evidence showing that these eco innovations are motivated by different external policy tools and internal firm specific factors our findings indicate that end of pipeline technologies and integrated cleaner production technologies are mainly driven by equipment upgrade motives with a view of improving efficiency while environmental regulations are effective in stimulating the end of pipeline technologies and environmental r d interestingly alongside government induced regulations we find that market factors mainly motivated by cost savings are effective in driving environmental r d finally iso14001 certification is effective in strengthening the positive impact of environmental management systems on both end of pipeline technologies and environmental r d while csr policies have no significant impact on motivating any of the eco innovations

reciprocity and resistance to comprehensive reform comprehensive reforms often fail despite being beneficial to society politicians may block comprehensive reforms in an attempt to form vote trading coalitions in which they benefit from a piecemeal reform at the expense of others because formal commitment devices for vote trading are frequently missing trust and reciprocity among legislators can play an important role for vote trading we investigate in a laboratory experiment whether legislators will impede comprehensive reforms in an attempt to form vote trading coalitions even if formal commitment devices for vote trading after reform failure are missing we find that open ballots allow for vote trading without commitment based on trust and reciprocity in turn legislators frequently reject efficient comprehensive reforms in such institutions

diffusion of a new product under network effects the us dvd market we formulate a model that captures the inter dependence between hardware demand and software supply indirect network effect in the dvd industry the identification of the network effect comes from the difference in software availability across two different formats vhs and dvd we find that a 1 increase in the number of dvd titles raises the demand for dvd players by 0 87 simultaneously a 1 increase in video player ownership leads to a 0 14 increase in the variety of video titles our simulations show that hardware manufacturers might be able to internalize the network externality to increase total industry revenues

business to business bargaining in two sided markets abstract bargaining regularly takes place on the business to business side of two sided markets however little is known about the consequences of these negotiations in this paper we allow the platform or a policy maker to choose between a standard design offering posted prices to both sides or a design with bargaining offering a posted price to consumers and negotiating with at least some firms we find that the platform pursues negotiations when it has a strong bargaining position and does so by targeting firms with the largest network effects while this behavior may appear exploitive we show that profits and welfare often align across platform designs this alignment stems from how bargaining incentivizes the platform greater platform bargaining power allows the platform to extract more of the network surpluses since it can convert more of the firm surplus into profits and this incentivizes the platform to draw in greater participation generating greater welfare these results suggest that platform and policy maker preferences often align in this setting

grabber holder dynamics and network effects in technology innovation abstract economists and marketing researchers have examined how network effects can have an impact on the adoption of technology and products and how an intrinsic inferior product or technology may dominate the market however their studies have not explained how a producer could create network effect for a new product and how after successfully creating the network effect for this product the producer could lose it in a short period of time while these studies provide insight into technology innovation after it happened they fail to shed light on understanding many of the surprises that we experience in the process the objective of this paper is to present a fundamental framework that helps us understand most of the surprising outcomes that we have seen in technology innovation processes especially the winners and losers in an innovation process the framework is built on a grabber holder dynamic model that captures how all the intelligent agents involved in an innovation shape the forces that either induce a strong network effect or destroy a network effect that is already in place the model can be used to explain many surprising events that have happened in technology innovation in this paper i apply the model to the personal computer innovation

the size distribution of innovating firms in the uk 1945 1983 a survey of 4 378 significant innovations shows that firms with fewer than 1 000 employees commercialized a much larger share than is indicated by their share of r and d expenditures innovations per employee have been consistently above average in firms with more than 10 000 employees and have become so in firms with fewer than 1 000 intersectoral variation in the size distribution of innovating firms can be explained as a function of r and d based technological opportunities and of technological ease of entry by user firms with principal activities outside the sector copyright 1987 by blackwell publishing ltd

network effects software provision and standardization in this paper we examine the software provision decision of software firms the provision decision by software firms determines the value and hence the market share of competing hardware technologies we show how the provision decision by software firms determines whether multiple hardware technologies are supported in equilibrium or whether there is de facto standardization with only one hardware technology supplied with software in equilibrium we show that when consumers place a high value on software variety there is a suboptimal amount of standardization by the market

entry in monopoly market this paper develops new empirical models of market concentration from game theoretic models of entry we construct our models from inequality conditions that describe entrants equilibrium strategies in simultaneous move and sequential move games and use them to study the effects of entry in isolated monopoly markets for new automobiles from estimates of the market size necessary to support one and two dealers we conclude that monopoly dealers do not block the entry of a second dealer we also find that entry does not cause price cost margins to fall by much

exclusionary pricing in markets with interdependent demands in this paper i use a simple model to study the competitive effects of exclusionary pricing involving two markets related by a positive demand externality it is shown that below cost pricing on one of these markets can allow an incumbent firm to exclude from both markets a more efficient rival which does not have a customer base yet however when exclusion occurs it is always socially optimal in addition under some circumstances there is inefficient entry the entrant wins both markets while the social optimum would require the incumbent to win them

competing by restricting choice the case of search platforms we show that a two sided matching platform can successfully compete by limiting the number of choices it offers to its customers while charging higher prices than platforms with unrestricted choice we develop a stylized model of online dating where agents with different outside options match based on how much they like each other starting from these microfoundations we derive the strength and direction of indirect network effects and show that increasing the number of potential matches has a positive effect due to larger choice but also a negative effect due to competition between agents on the same side agents resolve the trade off between these competing effects differently depending on their outside options for agents with high outside options the choice effect is stronger than the competition effect leading them to prefer an unrestricted choice platform the opposite is the case for agents with low outside options who then have higher willingness to pay for a platform restricting choice as

bottom up estimation of industrial and public r d investment by technology in support of policy making the case of selected low carbon energy technologies abstract this paper discusses a bottom up approach to estimate the level of r d investment by technology in areas where data are scarce it develops a four step methodology for the estimation of corporate r d investments at technology level this approach can overcome gaps in existing data by combining publicly available information in a novel way even though it introduces some uncertainty this is illustrated for a set of low carbon energy technologies that were identified as key for meeting europe s long term energy and climate objectives by the european strategic energy technology plan the paper finds that the aggregated r d investments dedicated to these technologies amounted to 3 3 billion in the eu in 2007 including public funding from european union member states and at eu level and industrial research activities from companies with headquarters registered in the eu the results allow conclusions on the european energy research policy to be drawn such as the dominance of industrial funds and have provided significant input to the european policy making in this field the paper ends with suggestions on how to further enhance the accuracy of the approach and how to widen its application to other sectors

production and innovation when techniques are tacit the case of education abstract the central theme of this paper is that the conventional economic theory of production does not hold even approximately in a field like education after examining the result of input output studies in education and the effect of government attempts to enhance education effectiveness we provide a sketch of a new production theory for sectors where techniques are poorly articulated and idiosyncratic

can voluntary approaches ever be efficient abstract despite their growing use only a few theoretical descriptions on the efficiency of voluntary approaches can be found this paper summarises the findings in this field so far it analyses the efficiency of voluntary approaches in three different ways 1 voluntary approaches as a bargaining process over abatement levels 2 voluntary approaches as a way to diminish informational asymmetries and 3 voluntary approaches as a voluntary over compliance mechanism from the models it seems as if the efficiency of voluntary approaches depends on several factors public supply of information auditing and the exchange of information between the negotiating parties are important elements further positive and negative inducements by the regulator can create incentives for the industry to engage in voluntary approaches also consumers demand for environmental quality can affect the environmental performance by industry either by the lobbying of interest groups or by a demand for products produced under environmental considerations

social capital for hire mobility of technical professionals and firm influence in wireless standards committees the movement of personnel between firms has been shown to have important implications for firms yet there has been little direct investigation of the underlying mechanisms we propose that in addition to their human capital mobile individuals carry social capital affecting the outcomes of the firms they join and leave by altering the patterns of interaction between firms in this study we examine how job mobility affects firm influence in a technical standards setting committee for u s wireless telecommunications we hypothesize and find that hiring individuals who are richer in social capital increases firm influence in technical standards setting committees by increasing the hiring firm s social capital we also find the benefits of hiring social capital are attenuated when an interfirm relationship is maintained by multiple individuals in contrast we find that the loss of personnel does not affect a firm s social capital or influence over standards directly but that it does have an effect on firm social capital and influence contingent on changes in the firm s business strategy in advancing these arguments we address the broader question of individuals as carriers of social capital and the conditions under which interpersonal connections are appropriable by firms

systems thinking market failure and the development of innovation policy the case of australia innovation policy is increasingly informed from the perspective of a national innovation system nis but despite the fact that research findings emphasize the importance of national differences in the framing conditions for innovation policy prescriptions tend to be uniform justifications for innovation policy generally relate to notions of market failure that are applicable in all nations in all conditions in this paper we develop a broad framework for nis analysis involving free market coordination and complex evolutionary system approaches within this framework we explore the evolving relationship between market failure and systems approaches to innovation policy in the case of australia drawing on information and analysis collected for a major review of australia s nis and the government s 10 year plan in response to it we show how the free market trajectory of policy making of past decades is being extended complemented and refocused by new approaches to complex evolutionary system thinking these approaches are shown to emphasize the importance of systemic connectivity evolving institutions and organizational capabilities nonetheless despite the fact that there has been much progress in this direction in the australian debate the predominant logic behind policy choices still remains one of addressing market failure and the primary focus of policy attention continues to be science and research rather than demand led approaches we discuss how the development and elaboration of notions of systems failure rather than just market failure can further improve policy making in the future

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

ecological economics and scientific controversies lessons from some recent policy making in the eec abstract contrasting the very limited scientific evidence on the forest dieback issue with the sudden adoption of policies on air pollution decided in the frg 1983 1984 and extended to the european community 1985 we propose an interpretative framework for the real internalization process at work in what was tantamount to a social crisis for public opinion the media and political actors we conclude that open scientific controversies on some environmental issues effects causes solutions pave the way for some actors to use the issue for their own techno industrial strategies quite alien to ecological constraints in cases of very high uncertainties on impacts it becomes impossible to apply conventional social cost benefit analysis scba as an optimizing tool we propose to develop economic analysis as a negotiation language and to give pride of place to the value of learning time and to the crucial role of technological pluralism as a condition for flexibility in the future

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

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

waves in consumption with interdependence among consumers this paper presents a model to analyze the development of consumption patterns when there are social interactions among consumers in particular a consumer in this model recognizes three reference groups a peer group of similar consumers with whom the consumer wishes to share consumption activities a distinction group from which the consumer wishes to distinguish him or herself and an aspiration group to which the consumer does not belong but wishes that he she did and with whom the consumer would like to share consumption activities the interplay of aspiration and distinction can lead to waves in consumption these can happen when for example the avant garde consumption of up market pioneers is copied by other types of consumer as the latter aspire to emulate the former the former in turn seek to distinguish themselves from these unwelcome companions by varying their consumption in consequence a particular consumption activity may start up market an then gradually proceed down the social spectrum more complex patterns with continuing cycles in consumption can also be found the paper argues that this model is not only applicable to the consumption behaviour of an elite or would be elite but is relevant in a wide range of consumption settings

globalizing carbon lock in this paper extends the arguments surrounding carbon lock in elaborated in unruh energy policy 28 2000 817 30 2002 317 to countries currently undergoing industrialization it argues that for numerous reasons industrializing countries are unlikely to leapfrog carbon intensive energy development on the contrary carbon lock in may be globalizing and could further constrain climate change mitigation options it is then argued that many policy recommendations ignore carbon lock in possibly limiting their potential for successful implementation the paper then discusses four policy approaches that appear to have advantages given lock in conditions it is recognized however that relative ease of implementation does not necessarily equate with superiority instead it is merely a path dependent outcome of past development decisions pursuing policies on the basis of relative implementation ease may help address the issue of climate change but could also result in sub optimal outcomes along other dimensions of sustainable development

from exogenous to endogenous economic networks internet applications economic agents behaviour is affected by their position in a network either exogenous or endogenous in which they interact with a sub set of neighbours only the network s links which may be generated by vertical and or horizontal relations or by more complex morphologies may explain the transition between dynamic equilibria and the instability of economic aggregates moreover networks shape strategic interaction among agents by determining their strategies the problem of access and interconnection particularly relevant in the internet is perhaps the best example a two way feedback between strategies and network structures arises instead when links are endogenous those features are clearly shown in the mechanism underlying the formation of peering links an dr d networks

a positive theory of fiscal deficits and government debt this paper considers an economy in which policymakers with different preferences alternate in office as a result of elections government debt is used strategically by each policymaker to influence the choices of his successors if different policymakers disagree about the desired composition of government spending between two public goods the economy exhibits a deficits bias that is debt accumulation is higher than it would be with a social planner the equilibrium level of debt is larger the larger is the degree of polarization between alternating governments and the less likely it is that the current government will be re elected

a global game with strategic substitutes and complements abstract we study a global game in which actions are strategic complements over some region and strategic substitutes over another region an agent s payoff depends on a market fundamental and the actions of other agents if the degree of congestion is sufficiently large agents strategies are non monotonic in their signal about the market fundamental in this case a signal that makes them believe that the market fundamental is more favorable for an action may make them less likely to take the action because of the risk of overcrowding

growth incentives to invest in a network externality environment firms that operate in the telecommunications industry often have to make large and risky investments in digital infrastructure this paper examines how firm size affects the incentive to invest in infrastructure projects in industry environments that incur substantial network externalities we suggest that in the presence of network externalities a firm s rate of growth first declines and then increases with the size of its user base an implication of this result is that firms may benefit from making investments in emerging digital infrastructure early enough to achieve a substantial user base and to gain that user base before other firms investments pre empt them the results mean that firms that undertake earlier successful investment may achieve preemption very quickly the sources of network externalities contribute to the incidence of strategic alliances in network industries particularly when coupled with the pressures of technical uncertainty copyright 1998 by oxford university press

social learning and dynamic pricing of durable goods we analyze the impacts of social learning sl on the dynamic pricing and consumer adoption of durable goods in a two period monopoly consumers can make either early uninformed purchases or late but potentially informed purchases as a result of social learning several results are derived first we identify the market conditions under which ex ante homogeneous consumers may choose to purchase at different times second equilibrium adoption may demonstrate inertia where all adopt late or frenzy where all adopt early in particular adoption inertia appears when sl intensity is reasonably high but may vanish when sl intensity exceeds a certain threshold third firm profits and social welfare first weakly decrease in sl intensity and may then jump up by a lump sum amount at the threshold sl intensity level mentioned above last we show that the firm potentially benefits from informative advertising or investing to cultivate more social learning

speeding up the internet regulation and investment in european fiber optic infrastructure in this paper we study how the coexistence of access regulations for legacy copper and fiber networks shapes the incentives to invest in network infrastructure to this end we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous entrants and test its main predictions using panel data from 27 eu member states over the last decade our theoretical model extends the existing literature by among other things allowing for heterogeneous entrants in internet access markets as we consider both other telecom and cable tv operators as entrants in the empirical part we use a novel data set including information on physical fiber network investments legacy network access regulation and recently imposed fiber access regulations our main finding is that more stringent access regulations for both the legacy and the fiber networks harm investments by incumbent telecom operators but in line with our theoretical model do not affect cable tv operators

social preferences and voting on reform an experimental study debating over efficiency enhancing but inequality increasing reforms accounts for the routine business of democratic institutions fernandez and rodrik 1991 hold that anti reform bias can be attributed to individual specific uncertainty regarding the distribution of gains and losses resulting from a reform in this paper we experimentally demonstrate that anti reform bias arising from uncertainty is mitigated by social preferences we show that paradoxically many who stand to lose from reforms vote in favor because they value efficiency while many who will potentially gain from reforms oppose them due to inequality aversion

the unequal benefits of fuel subsidies a review of evidence for developing countries summary this paper reviews evidence on the impact of fuel subsidy reform on household welfare in developing countries on average the burden of subsidy reform is substantial and is approximately neutrally distributed across income groups a 0 25 decrease in the per liter subsidy results in a 5 decrease in income for all groups more than half of this impact arises from the indirect impact on prices of other goods and services consumed by households fuel subsidies are a costly approach to protecting the poor due to substantial benefit leakage to higher income groups in absolute terms the top income quintile captures six times more in subsidies than the bottom

the influence of regulations on innovation a quantitative assessment for oecd countries abstract regulatory framework conditions have been identified as important factors influencing the innovation activities of companies industries and whole economies however in the empirical literature the impacts of regulation have been assessed as rather ambivalent for innovation different types of regulations generate various impacts and even a single type of regulation can influence innovation in various ways depending on how the regulation is implemented the endogenous growth approach developed by carlin and soskice 2006 and empirically applied by crafts 2006 which determines endogenously the rate of technological progress and therefore innovation allows a conceptual analysis of the influence of different types of regulation on innovation in general the negative effect of compliance costs should be compared with the more dynamic effect of regulations generating additional incentives for innovative activities based on this approach we derive hypotheses on the impact of different specific regulations on innovation we differentiate between economic social and institutional regulations following the oecd taxonomy on regulations existing economic analyses are surveyed which are characterised by rather heterogeneous approaches data bases and results the paper aims to apply a comprehensive and comparative approach to investigate quantitatively the innovation impacts in 21 oecd countries using panel data for the period between 1998 and 2004 in summary the empirical results confirm the hypotheses derived from the conceptual theoretical framework determining technical progress and innovation endogenously and allowing a distinction between short term and long term effects consequently the theoretical approach is an appropriate starting point for the empirical analysis of the influence of different regulations on innovation

coordinating adoption decisions under externalities and incomplete information abstract a monopolist sells a good whose value depends on the number of buyers who adopt it as well as on their private types the seller coordinates the buyers adoption decisions based on their reported types and charges them the price based on the number of adoptions we study ex post implementable sales schemes that are collusion proof and show that under the revenue maximizing scheme more buyer types are willing to adopt when there are more adoptions and the number of adoptions is maximized subject to the participation constraints

rational incompatibility with international product standards abstract international product standardization enables traditional price based competition but the existence of redesign costs or network effects creates market frictions that diminish the incentive to standardize if there already exists a different technology in an established market this leads to multi attribute competition between products and will generally reduce trade flows not only do incumbent firms using a different technology have an incentive to deviate from an international standard but a host country government concerned for its consumers welfare has no incentive to enforce the international standard and may even value deviation from the international standard through technical barriers to trade

the diffusion of clean technologies a review with suggestions for future diffusion analysis abstract this article gives an overview of the literature on clean technology diffusion followed by suggestions for future analysis findings from diffusion analysis are presented in the form of 10 stylised facts helping the reader to see the forest for the trees the overall conclusion is that the diffusion of clean technology same as the diffusion of normal innovations is governed by endogenous mechanism epidemic learning and learning economies and by exogenous mechanisms policy is important for clean technology diffusion but other factors are important too the characteristics of the clean technology absorptive capacities of potential adopters and the age structure of capital it is often overlooked that companies have a choice they can choose between an end of pipe solution a process change adaptation and a change of process substitution this means that the diffusion and evolution of one clean technology will be at the expense of the diffusion of another clean technology something overlooked in studies on clean technology diffusion further research is needed on the influence of public policy on clean technology choice expectations about learning economies and prices adjustment costs network externalities and complementary innovations on clean technology adoption choices

the development and use of machine tools in historical perspective abstract improvements and diffusion of machine tools have had a major impact on productivity in manufacturing industry since the industrial revolution the impact has been both direct and indirect the direct impact consists of rising labor productivity through the use of faster more accurate more mechanized machines and of the higher capital productivity through higher operating rates greater reliability and higher utilization rates the indirect impact arises as the use of new or improved machine tools has necessitated or facilitated organizational changes affecting both labor capital raw materials and energy the magnitude of these impacts has varied over the years with the areas of application as new production methods have made possible entirely new products or lowered the cost of existing products sufficiently to create new markets the first part of the paper contains a review of the historical development of machine tool technology since the industrial revolution paying particular attention to the role of interaction between producers and users of machine tools the second part focuses on the way in which recent development differs from that in earlier periods in particular it is found that the major changes in machine tool technology from the so called american system of manufactures in the early 19th century to the development of detroit automation in the 1950s have tended to improve mass production methods by contrast the development of numerical control beginning in 1948 has opened up the possibility of extending industrial production methods and automation to areas previously characterized more by handicraft methods even though this technology is not yet fully utilized it is clear that the economics of industrial production has been revolutionized by the cost reduction of small scale production relative to large scale and the degree of flexibility offered by the technology the third section of the paper deals with the present development trends particularly discussing the increasing importance of flexibility and the shifting emphasis from development of individual pieces of machinery to integration and control of entire manufacturing processes i a through the use of industrial robots the reasons for the need for greater flexibility in manufacturing are also identified

the market value of rarity abstract most theories of demand assume that consumers value the characteristics of products but are unconcerned with how many other consumers also consume the product however several theories of demand argue that consumers can value the exclusivity of possessing a rare object we test this implication on a particular collectible rare coins our paper examines the case of coins of a given type and identical quality that have mintages in different quantities this allows us to exclude the common case in which rarity or price itself is an indicator of quality for our sample rarer coins command higher prices rarity in the form of original mintage more strongly influences the market price than does collectibility as represented by the rarest coins of each mint mark or year we also point out that here may be other goods such as automobiles for which rarity may influence market demand

local network externalities and market segmentation this paper models interaction between groups of agents by means of a graph where each node represents a group of agents and an arc represents bilateral interaction it departs from the standard katz shapiro framework by assuming that network benefits are restricted only amongst groups of linked agents it shows that even if rival firms engage in bertrand competition this form of network externalities permits strong market segmentation in which firms divide up the market and earn positive profits the analysis also shows that some graphs or network structures do not permit such segmentation while for others there are easy to interpret conditions under which market segmentation obtains in equilibrium c 2009 elsevier b v all rights reserved

the politics of government decision making a theory of regulatory capture the paper develops an agency theoretic approach to interest group politics and shows the following 1 the organizational response to the possibility of regulatory agency politics is to reduce the stakes interest groups have in regulation 2 the threat of producer protection leads to low powered incentive schemes for regulated firms 3 consumer politics may induce uniform pricing by a multiproduct firm 4 an interest group has more power when its interest lies in inefficient rather than efficient regulation where inefficiency is measured by the degree of informational asymmetry between the regulated industry and the political principal congress

developing science technology and innovation indicators what we can learn from the past the science technology innovation system is one that is continuously and rapidly evolving the dramatic growth over the last twenty years in the use of science technology and innovation sti indicators appears first and foremost the result of a combination between on the one hand the easiness of computerized access to an increasing number of measures of sti and on the other hand the interest in a growing number of public policy and private business circles in such indicators as might be expected in societies which increasingly use organised science and technology to achieve a wide variety of social and economic objectives and in which business competition is increasingly based on innovation as highlighted on the basis of 40 years of indicators work frontiers and characteristics that were important last century may well no longer be so relevant today and indeed may even be positively misleading

economic instruments and induced innovation the european policies on end of life vehicles abstract the paper addresses the mechanisms by which specific economic instruments based on the producer responsibility principle prp can influence innovation when environmental policy has impact on very complex industrial subsystems we consider the eu policy on end of life vehicles directive 2000 53 ec on elvs as a representative case study of multiple industry prp instrument dynamic efficiency problems in order to achieve ambitious policy targets on elv recovery recycling reuse interrelated sequences of single innovations in both upstream car making and downstream car recycling recovery should take place we explore the extent to which the introduction of a free take back ftb instrument can influence industrial actors in contributing to innovation paths that are still marked by technological uncertainty evolving capabilities and different cost benefit balances for actors themselves we conclude that differently from static approaches in which the ei and its formulation is neutral with respect to policy effectiveness the dynamic efficiency of eis in elv like problems depends both on where along the production to waste chain and how in terms of net cost allocation the specific incentive is introduced consequently in order to generate a policy desired innovation path the way in which the ei related incentive allocated to a certain industry is transmitted to other industries whether upward or downward along the chain is also relevant disregarding these effects can imply a dissipation of innovation incentives and the generation of regulation induced rents for some actors cannot be ruled out policies based on prp should consider eis in conjunction with enforceable voluntary agreements

configuring value for competitive advantage on chains shops and networks building on thompson s 1967 typology of long linked intensive and mediating technologies this paper explores the idea that the value chain the value shop and the value network are three distinct generic value configuration models required to understand and analyze firm level value creation logic across a broad range of industries and firms while the long linked technology delivers value by transforming inputs into products the intensive technology delivers value by resolving unique customer problems and the mediating technology delivers value by enabling direct and indirect exchanges between customers with the identification of alternative value creation technologies value chain analysis is both sharpened and generalized into what we propose as a value configuration analysis approach to the diagnosis of competitive advantage with the long linked technology and the corresponding value chain configuration model as benchmark the paper reviews the distinctive logic and develops models of the value shop and the value network in terms of primary activity categories drivers of cost and value and strategic positioning options 1998 john wiley sons ltd

to segregate or to integrate education politics and democracy how is the quality of public education affected by the presence of private schools for the rich theory and evidence suggest that the link depends crucially on the political system we develop a theory that integrates private education and fertility decisions with voting on public schooling expenditures we find that the presence of a large private education sector benefits public schools in a broad based democracy where politicians are responsive to low income families but crowds out public education spending in a society that is politically dominated by the rich the main predictions of the theory are consistent with state level data and micro data from the u s as well as cross country evidence from the programme for international student assessment study

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

network effects market structure and industry performance abstract this paper analyzes oligopolistic markets with network externalities exploiting a minimal complementarity structure on the model primitives that allows for pure network goods we prove existence of non trivial fulfilled expectations equilibrium we formalize the concept of industry viability investigate its determinants and show that it improves with more firms in the market and or by technological progress these results enlighten some well known conclusions from case studies in the management strategy literature we also characterize the effects of market structure on industry performance which depart substantially from ordinary markets the approach relies on lattice theoretic methods supplemented with basic insights from nonsmooth analysis

prospective voluntary agreements for escaping techno institutional lock in the paper looks for evolutionary policy responses to techno institutional lock in a persistent state that creates systemic market and policy barriers to technological alternatives we address the coordination role for authorities rather than corrective optimisation and elaborate three evolutionary policy objectives including fostering of i the diversity of technological options ii common vision for the implementation of technological alternatives and iii changes in social and physical networks we use these objectives to analyse documented experiences from environmental voluntary agreements and foresight activities we argue that combining the virtues of these tools into a new policy tool named prospective voluntary agreement can help facilitate an escape from techno institutional lock in the merit of the prospective voluntary agreement lies with the enhancement of collaborative policy cultures and inter sectoral and interdisciplinary stakeholder learning that creates commitment to desired action for escaping lock in d 2005 elsevier b v all rights reserved

a positive theory of flexibility in accounting standards abstract we develop a positive theory of accounting standards when standards generate network externalities and differ in the amount of reporting discretion or flexibility they provide firms we evaluate expected value maximizing firms preferences between two standards regimes rigid and flexible as the number of firms subject to each standard varies as the organization of the securities market varies and as the mapping from the underlying economics of the firms transactions to the accounting reports produced under the two standards vary we also compare firms preferences between the two regimes to the preferences of profit maximizing traders in the firms securities

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

testing political economy models of reform in the laboratory a fast growing theoretical literature on the political economy of reform has provided a sizable collection of models that have deepened our understanding concerning how distributional conflict manifests itself in the political process and can prevent efficiency enhancing economic reform from taking place see e g allan drazen 2000 ch 10 13 for an insightful review unfortunately systematic empirical work that provides direct tests of the validity and significance of the mechanisms articulated in these models has been limited as torsten persson and guido tabellini 2000 p 481 note in their evaluation of the larger political economy literature the gap between theory and evidence is a final weakness of the existing literature w hen there is empirical work its ties to the underlying theory are often loose and are not tied well to the extensive form games or theoretical predictions in theoretical work ideally we would like more empirical work derived from theory as opposed to informed by theory one reason for the lack of such empirical studies is that most of these often gametheoretic models explain policy outcomes as a result of strategic interaction of forward looking agents direct tests of these models using field data are subject to the same difficulties that researchers have faced when testing gametheoretic models in other areas such as industrial organization since qualitative features of the equilibria often depend sensitively on the specific assumptions of the game structure see richard schmalensee 1988 pp 675 76 gilles saint paul 2000 in addition the politicaleconomy literature of reform explains policy outcomes using political variables such as the distribution of voters preferences and the nature of political institutions see e g drazen 2000 stephan haggard 2000 the time variation of these variables is often limited leading to a classic identification problem and making direct tests of theoretical models difficult saint paul 2000 laboratory studies allow the researcher to manipulate explanatory variables of a theory as treatment variables so such studies should be helpful in partially overcoming these difficulties and can complement field empirical work on reform the study of reform also poses new challenges to experimental economists and a dialogue between political economists and experimental economists can enable both sides to capture gains from trade this paper aims to illustrate this using an experimental study of the model in the influential paper by raquel fernandez and dani rodrik 1991

toward prospective voluntary agreements reflections from a hydrogen foresight project abstract there is substantial interest in promoting the emergence of a hydrogen based energy economy if successful this would represent a policy led discontinuous transition away from existing fossil fuel based systems such a move has few precedents and few policy tools exist to manage such a complex and uncertain endeavour furthermore existing hydrocarbon energy systems can be considered techno institutional complexes tic which have developed through the path dependent co evolution of physical technologies and social institutions these complexes have numerous structures that ensure their perpetuation and create important barriers to the implementation of alternatives like hydrogen based systems the authors explore the application of prospective voluntary agreements pva as a policy tool process that can help facilitate a move towards a hydrogen based economy through foresight and negotiation from this perspective we look at the recent case of the nordic hydrogen energy foresight project for evidence

product compatibility as a signal of quality in a market with network externalities abstract in this paper i consider the compatibility decision as a signaling device of the quality of a newly introduced technology of which users are not informed provided that firms are located sufficiently far apart in hotelling s 0 1 interval i find separating equilibria where low compatibility signals high quality this possible separation is due to the fact that low compatibility is more advantageous to the high quality entrant than to the low quality entrant since it can prevent users of the established technology from enjoying network benefits from the new technology very much

the emergence of an educational tool industry opportunities and challenges for innovation in education the paper addresses two issues one concerns the general conditions and procedures involved in the emergence of a tool industry tool industries emerge and evolve as a collection of capital goods and tool inventors and manufacturers one of our goals is to use some of the works on historical cases to build a heuristic framework concerning the main conditions for the emergence and development of tool industries the other issue is more factual and involves the question whether a tool industry is today emerging in the area of education the paper describes the emergence of a population of firms specialised in developing and commercialising educational tools and instructional technologies and discuss whether this trend can be seen as part of the solution to the innovation deficit and cost disease problems in this sector

technical compatibility and the mode of foreign entry with network externalities we examine the preferences of a foreign firm and a local government over two modes of foreign direct investment de novo entry and acquisition of the domestic incumbent two crucial features of the model are network externalities and partial incompatibility between the domestic and the foreign technology the relative welfare impact of the two entry modes depends on the degree of market competition and the strength of the network externality the clash between the foreign firm s choice and the local government s ranking of the two entry modes can motivate limits on the degree of foreign ownership of the local firm ce texte examine les preferences d une firme etrangere et d un gouvernement du pays hote quant a deux modes d investissement direct de l etranger entree de novo de la firme etrangere versus acquisition d une firme domestique en place deux facteurs pris en compte sont la presence d externalites de reseau et d incompatibilite partielle entre la technologie locale et celle introduite par la firme etrangere l impact relatif des modes d entree sur le mieux etre local depend du degre de concurrence sur le marche et de l importance des externalites de reseau le conflit entre les preferences de l entreprise etrangere et les preferences du gouvernement local peuvent etre a la source de politiques qui limitent le degre de proprieteetrangere permis

how to play the names game patent retrieval comparing different heuristics patent statistics represent a critical tool for scholars statisticians and policy makers interested in innovation and intellectual property rights many analyses are based on heterogeneous methods delineating the inventors or firms patent portfolios without questioning the quality of the method employed we assess different heuristics in order to provide a robust solution to automatically retrieve inventors in large patent datasets patstat the solution we propose reduces the usual errors by 50 and casts doubts on the reliability of statistical indicators and micro econometric results based on common matching procedures guidelines for researchers ttos firms venture capitalists and policy makers likely to implement a names game or to comment on results based on a names game are also provided

the perils of polarization economic performance in the postcommunist world perhaps the most striking feature of the postcommunist transformation is the tremendous variation in rates of economic growth across countries to account for these differences this article develops an alternative to the j curve and partial reform views that currently dominate discussions of the politics of economic reform this approach treats economic performance as a political struggle between ex communist and anticommunist factions engaged in a war of attrition over economic and political resources using a pooled time series analysis of economic growth across twenty five postcommunist countries for the period 1990 98 it finds that political polarization between ex communist and anticommunist factions has had a devastating effect on economic growth where these competing factions have had roughly equal power and have struggled over the economic rules of the game as in bulgaria or ukraine economic growth has been slow in contrast where either ex communist or anticommunist factions have dominated the political scene as in estonia or uzbekistan economic performance has been much better in addition economic growth has followed the electoral calendar in polarized countries as elections approach and the odds of a change in economic policy increase growth rates have plummeted in polarized countries these findings have implications for studies of the postcommunist transformation the political business cycle and the politics of economic reform more generally

polarizing information and support for reform abstract we examine whether political polarization is an obstacle to common value reforms we conduct experiments in two ideologically polarized countries the united states and egypt subjects vote between enacting a reform which yields higher expected financial payoffs than the costs of implementation for all but has indirect differential benefits for supporters of only one group of voters versus not enacting the reform and everyone receiving lower payoffs we find that when the groups are polarized ideologically subjects are less likely to vote for reform when informed that another political group would differentially benefit and more likely to support reform should their own group benefit more when subjects are told that one group will differentially benefit from reform they are significantly more likely to explain their vote as being influenced by their own group membership in contrast we find that when subjects are organized into nonpolarized groups group membership predicts reform support less and when there are no differential benefits for a particular group the effect of membership on support is significantly reduced hence we find that the effect of polarization on support for common value reform is contingent on the existence of indirect differential benefits and the degree of ideological polarization of the groups who receive those benefits
