total factor productivity and the environmental kuznets curve a comment and some intuition abstract chimeli and braden chimeli ariaster b braden john b 2005 total factor productivity and the environmental kuznets curve journal of environmental economics and management 49 366 380 derive a necessary and sufficient condition under which inter country differences in total factor productivity can yield an environmental kuznets curve they argue that their results emphasize the importance of differences in total factor productivity across countries as well as the need for decreasing returns to scale in pollution abating technologies for the existence of an environmental kuznets curve we show that their proposition 1 is equivalent to proposition 2 in lieb lieb christoph m 2002 the environmental kuznets curve and satiation a simple static model environment and development economics 7 429 448 this implies that even in chimeli and braden s model contemporaneous changes in the marginal rate of substitution between environmental quality and consumption on the demand side and the marginal rate of transformation between these goods on the supply side drive the pollution income relationship this is a very general condition that does not rely on either differences in total factor productivity or decreasing returns to scale in abatement and which is widely applicable

questioning the empirical basis of the environmental kuznets curve for co2 new evidence from a panel stationarity test robust to multiple breaks and cross dependence abstract this paper investigates the time series properties of per capita co2 emissions and per capita gdp levels for a sample of 86 countries over the period 1960 2000 for that purpose we employ a state of the art panel stationarity test which incorporates multiple shifts in level and slope thereby controlling for cross sectional dependence through bootstrap methods our analysis renders clear cut evidence that per capita gdp levels are nonstationary for the world as a whole while per capita co2 is found to be regime wise trend stationary the analysis of country groups shows that for africa and asia per capita co2 is best described as nonstationary while per capita gdp appears stationary around a broken trend in addition we find evidence of regime wise trend stationarity in both variables for the country groups consisting of america europe and oceania the results of our analysis carry important implications for the statistical modelling of the environmental kuznets curve for co2 since the differing order of integration in both variables for the world as a whole and for africa and asia calls into question the validity of panel cointegration techniques which assume that both variables are nonstationary and cointegrated with one another cointegration techniques would not be appropriate either for the case of america europe and oceania which are characterised by per capita gdp and co2 emissions being stationary around a broken trend similar conclusions are reached when we analyse country groups based on levels of development failure to properly characterise the time series properties of the data by not controlling for an unknown number of structural breaks and for cross sectional dependence could be responsible for the fragility and lack of robustness surrounding the estimation of environmental kuznets curves

liberalisation and r d in network industries the case of the electricity industry abstract electricity sector liberalisation has coincided with a significant decline in r d spending this paper reviews the industrial organisation literature on r d and innovation to explore the likely causes of the decline in r d spending in the electricity sector meanwhile r d productivity and innovative outputs in utilities and equipment suppliers appear to have improved however a lasting decline in r d expenditure can have a negative long term effect on technological progress and innovation in the sector we conclude that the decline in r d could have been predicted from the literature we also discuss the need to reorient the post liberalisation technology policy

industrial and residential electricity demand dynamics in japan how did price and income elasticities evolve from 1989 to 2014 abstract this study estimates the price and income elasticities of industrial and residential electricity demand in japan with the annual data from 1989 to 2014 a time varying parameter tvp model with the kalman filter is applied to monitor the evolution of consumer behaviors in the post bubble period given the exogenous shock financial crisis in 2008 and the structural breaks electricity deregulation and fukushima daiichi crisis the tvp model can provide a robust estimation of elasticities and can detect the outliers and the structural breaks the results suggest that both industrial and residential consumers become less sensitive to price after the electricity deregulation and the financial crisis and more sensitive to price after the fukushima daiichi crisis especially the industrial sector is less sensitive to price after the retail deregulation by contrast the income elasticities of industrial and residential sector consumers are stable during the examined period results also indicate that a negative relationship exists between the price elasticity of electricity demand and the price level of electricity after the electric sector deregulation some insights on the further electric sector reform and the environmental taxation in japan are also provided

quality improvements and the incentive to leapfrog abstract in a model of an uncovered market of vertically differentiated products incentives of non identical duopolists to improve the technological maximum quality are analyzed it is assumed that initially firms offer products with different qualities and that the r d cost function changes exogenously this induces a reconsideration of firms quality decisions both firms have the same r d costs for improving the maximum quality quality changes within the existing quality range are assumed to incur only fixed adjustment costs it is shown that the firm which initially is in the low quality position always has a higher incentive to improve industry s quality than its rival if adjustments costs are sufficiently high persistence of dominance may occur for a low degree of initial differentiation low adjustment costs and r d cost functions with a high slope

why and how to subsidise energy r d lessons from the collapse and recovery of electricity innovation in the uk the uk electricity sector liberalisation was a pioneer in the worldwide reform trend and its reform model and outcomes have been the subject of many studies however lesser known are the effects of privatisation market based reforms and incentive regulation of networks on research and development as well as patenting activities in the sector this paper updates our previous studies of this subject and discusses the recent developments in the innovative activities in the uk electricity sector we find that in recent years the initial absence of support policies and the subsequent decline in innovation efforts in the aftermath of the reform has resulted in efforts towards forming an energy technology and innovation policy although we already observe some positive outcomes from these efforts we discuss whether the balance of the innovation efforts are calibrated appropriately and whether the institutional framework can be further improved to promote long term progress

disruption costs learning by doing and technology adoption abstract we study technology adoption in a dynamic model of price competition adoption involves disruption costs and learning by doing because of disruption costs the adopting firm begins in a market disadvantage which may persist if its rival captures the customers that the adopting firm needs to learn the technology the prospect of future rents by the rival results in i a failure to adopt socially efficient technologies ii an equilibrium preference for technologies that are learned faster but have lower social value and iii more technologies being adopted if more firms enter the market

does sticky information affect the locus of innovation evidence from the japanese convenience store industry abstract scholars have long discussed the locus of innovation and its determinants there is empirical evidence that innovations can be developed by those holding any of a number of functional relationships to them such as manufacturers users or materials suppliers past studies have considered two factors important in predicting the functional locus of innovation one is expected profit of a player involved in the innovation and the other is stickiness of innovation related information although some studies have shown empirically the link between an innovator s expected profits and the locus of innovation no research has yet been conducted to test the hypothesized relationship between stickiness of innovation related information and the locus of innovation in the study reported upon here i explore relationships between these two variables via a study of 24 innovations for the japanese convenience store industry my study shows empirically that stickiness of innovation related information does have the hypothesized relationship to the functional locus of innovation i discuss implications of these findings and some directions for future research

energy research and r d indicators an lmdi decomposition analysis for the iea big 5 in energy research abstract the literature has always shown that there are two important factors in the improvement of a country s research output gross domestic product gdp and r d expenditures taking the discussion a step further and in an effort to provide policy recommendations on what is needed to boost research capacity this paper aims at decomposing the change in energy research papers of five countries australia canada germany uk and us into four factors gdp r d intensity ratio of total r d to gdp energy r d rate of return or productivity number of energy related papers per unit of energy r d expenditure and energy r d priority share of energy r d to total r d expenditure the findings show a general trend in the sign of the four effects on research for all five countries energy r d productivity energy r d priority and gdp are mostly found to be positive contributors while the r d intensity a negative one this pattern has exceptions that are more prominent during periods where economic growth is constrained for example during 2008 09 the results have policy implications not only for these five countries but also for developing countries low gdp that aim at contributing more to the energy related research output globally

a model of the evolution of duopoly does the asymmetry between firms tend to increase or decrease this paper is an attempt to identify some of the factors that affect the evolution of market structure in a model of dynamic competition between two firms the stochastic evolution of the state of competition depends on the respective effort rates of the firms the question is whether the current leader works harder than the laggard does the gap between firms tend to increase or decrease we show that several effects are at work the state tends to evolve in the direction where joint payoffs are greater since joint payoffs are related to joint product market profits less joint effort costs there are two classes of effect the joint profit effect and various joint cost effects the latter result in part from the pattern of profits and in part from endpoint effects that give relief from efforts asymptotic expansions illuminate these influences moreover we show by numerical simulation that there is another kind of joint cost effect the pattern of joint effort costs can influence the pattern of evolution of market structure and the evolution of the pattern of market structure can influence the pattern of efforts in a mutually self reinforcing manner in particular there may be equilibria in which this last effect means that the laggard works harder than the leader even though all the other effects work in favour of the leader

competition or predation consumer coordination strategic pricing and price floors in network markets although network effects can make predation more likely to succeed we find that the leading anti predation rules may lower or raise efficiency and consumer welfare in network markets we find that a the extensive debates about the correct measure of cost on which to base price floors are unlikely to be productive b the ordover willig rule that is widely thought to be correct in theory but difficult to apply in practice is in fact incorrect in theory and c efficient price floors would have to depend on consumer expectations and coordination processes that are unlikely to be observable in practice

when do auctions ensure the welfare maximizing allocation of scarce inputs we determine when an unfettered auction will ensure the welfare maximizing allocation of a scarce input that enhances product quality and may reduce production costs a supplier values the input for this use value and for its foreclosure value because once the input is acquired it is unavailable to rivals an unfettered auction often ensures the welfare maximizing allocation of an input increment however it can fail to do so when the input would increase relatively rapidly the competitive position of a rival with a moderate competitive disadvantage bidder handicapping that ensures auctions generate welfare maximizing input allocations differ from standard handicapping policies

innovation performance of the us american and european electricity supply industry abstract using a production function approach based on cobb douglas this analysis relates r d efforts of 32 electric utilities on both sides of the atlantic to their performance in terms of labour productivity we find that higher r d levels generally have a positive impact on revenues however only in the sub sample of 16 electricity suppliers in europe this effect is significant knowledge spill over effects can be estimated for the us american sub sample since us utilities have bundled their r d efforts in a centralized research institution and have to report that data our analysis reveals though that collaborative research efforts do not lead to positive spill overs at the assumption of a time delay of one year

interactions between economic growth and environmental quality in shenzhen china s first special economic zone the relationship between economic development and environmental quality is a debated topic environmental kuznets curve ekc is one prominent hypothesis positing an inverted u shaped development environment relationship here we test this hypothesis using data from shenzhen people s republic of china established in 1980 as the first special economic zone in china shenzhen has developed from a small village into a large urban industrial agglomeration with the highest income level in the country the enormous expansion of infrastructure industrial sites and urban settlements has profoundly changed the local environment we utilize environmental monitoring data from shenzhen on concentration of pollutants in ambient air main rivers and near shore waters from 1989 to 2003 the results show that production induced pollutants support ekc while consumption induced pollutants do not support it c 2006 elsevier b v all rights reserved less

entry and competitive dynamics in the mobile telecommunications market abstract we propose an extension of the gans stern gans j s stern s 2003 the product market and the market for ideas commercialization strategies for technology entrepreneurs research policy 32 2 333 350 framework that includes entry by existing firms an incumbent firm possessing complementary assets and strong appropriability is in a formidable position teece d j 1986 profiting from technological innovation implications for integration collaboration licensing and public policy research policy 15 6 285 305 however a de alio entrant can leverage complementary assets to enter along a new technological trajectory and then develop appropriability we illustrate how several mobile telecommunications firms ericsson nokia and samsung pursued this strategy to catch up with the market leader motorola we also identify several shortcomings in motorola s approach it was too inward looking in developing technologies but ironically not inward looking enough in exploiting its most valuable patents

economics and the self organisation approach alfred marshall revisited the economics of alfred marshall is reassessed in the light of new developments in the natural sciences whereby a nonequilibrium thermodynamic approach is adopted to analyze self organization in dissipative structures it is argued that there is a clear correspondence between marshall s treatment of time irreversibility and this modern approach particularly when the latter is set in an informational context thus his principles is viewed as a very useful starting point in adapting the self organization approach for application in economics the main features of such a post marshallian approach to economics are discussed and compared with the mechanical approach of neoclassicism copyright 1993 by royal economic society

when do stronger patents increase continual innovation under continual innovation greater patent strength expands innovating firms profit against imitation but also shifts profit from current to past innovators we show how the impact of patents on innovation as determined by these two opposing effects varies with industry characteristics when the discount factor is sufficiently high the negative profit division effect is negligible and innovation monotonically increases in patent strength otherwise innovation has an inverted u relationship with patent strength and stronger patents are more likely to increase innovation when the discount factor or the fixed innovation cost is higher we also show how the impact of patents on innovation may change with firms innovation capability and with the intensity of competition from imitators

r d and internal finance a panel study of small firms in high tech industries since joseph schumpeter economists have argued that internal finance should be an important determinant of r d expenditures yet almost without exception previous empirical studies have not found evidence of such a relation using newly available data the authors investigate this puzzle with a panel of 179 small firms in high tech industries under each estimation strategy they employ the authors find an economically large and statistically significant relationship between r d investment and internal finance their results are consistent with the view that because of capital market imperfections the flow of internal finance is the principal determinant of the rate at which small high tech firms acquire technology through r d copyright 1994 by mit press

is the growth of small firms constrained by internal finance this paper examines the long standing theory that the growth of small firms is often constrained by the quantity of internal finance under plausible assumptions when financing constraints are binding an additional dollar of internal finance should generate slightly more than an additional dollar of growth in assets this quantitative prediction should not hold for the relatively small number of firms which access external equity we test these predictions with a panel of more than 1 600 small firms and find that the growth of most firms is constrained by internal finance our results have implications for several different research literatures including models of firm growth

r d investment of electricity generating firms following industry restructuring abstract since electricity market restructuring questions over adequate levels of r d investments persisted using an unbalanced panel data of 70 electricity generating firms across 15 organisations of economic co operation and development countries from 1990 to 2008 this paper empirically examines the impacts of entry liberalization allowing third party access establishing a wholesale market and deregulating a retail market vertical unbundling privatization and firm size on r d investments entry liberalization is associated with a decline in r d investment establishing a wholesale market exhibits the greatest negative effects on r d investment regulated tpa and retail market deregulation also decrease r d the effect of privatization is not independently salient but interacts with a wholesale pool to lower r d investments large firms spend more on r d investment than small firms results indicate that the restructuring of the electricity industry reduces r d investment which may be detrimental to the reliability and the efficiency of the electricity system as well as to the creation and maintenance of the innovation capabilities necessary to address demand and environmental concerns

relationships between water pollutant discharges per capita pdcs and indicators of economic level water supply and sanitation in developing countries abstract water pollutant discharges per capita pdcs as indicators to evaluate quantitatively domestic wastewater pollutant discharges to the ambient water were applied to eight international coastal zones and lakeside regions statistical analyses were conducted to find the relationships between pdcs and water sanitation and economic parameters including purchase power parity based gross national income ppp gni per capita proportions of access to safe drinking water and appropriate sanitation domestic water usage amount and integrated parameters of water sanitation and economic indicators wsei1 2 two of the important findings from the regression analyses results were pdc bod correlated with ppp gni per capita with 3rd order regression and pdc tp correlated with wsei1 positively with 10 significance besides smaller adjusted regression coefficients t values of partial regression coefficients between pdc tp and wsei2 increased in the most analyses cases compared to those between pdc tp and wsei1 which showed improvement of the indices empirical estimations were also conducted based on the regression analyses results and distributions of pdcs and ppp gni per capita on the graphs six components generated by the principle component analysis pca contributed 99 of the parameters the first component represented access to sanitation second one represented household connection of safe drinking water third one represented areal equipment of water supply in urban area fourth one represented domestic water usage amount fifth one represented areal equipment of water supply and sixth one represented income per capita and sanitation although some statistically significances of the multiple linear regression analysis were observed the relationships between pdcs and the water supply parameters were considered as complicated in regards to areal equipment and household connection and in whole country and in urban area possible chronological relationships between pdc bod and water supply equipment were considered based on the results of the multiple linear regression analyses and pca based on the considerations of the water pollutant discharges and the economic related parameters relationships domestic wastewater treatment facility deployments and improvements on pollutant discharges reduction for the water quality improvement in the receiving water bodies were recommended which would lead the relationship curves between the water sanitation and economic related indicators and pdcs to move downward

unintended consequences energy r d in a deregulated energy market abstract many advanced industrialized nations are substantially reducing their national public and private investments in energy research and development r d driven in part by changes occurring as a result of the deregulation of these nations energy sectors in particular funding for strategic energy r d aimed at developing future energy supply options eg fusion fission clean fossil energy renewable energy has been decreased substantially in both the public and private sectors in many of these nations these trends are now starting to be seen in the united states as it moves towards the deregulation of the nation s utilities the magnitude of the reductions in support for energy r d in the public and private sectors and the shift towards decidedly shorter term r d has profound implications for nations approaching deregulation though utility customers may be short term winners from the deregulation of utilities by paying less for energy a national failure to invest in energy r d is very likely to have long term negative impacts on national energy sectors the economies and environmental wellbeing

exploring the environmental kuznets hypothesis theoretical and econometric problems focussing on the prime example of co2 emissions we discuss several important theoretical and econometric problems that arise when studying environmental kuznets curves ekcs an ekc refers to an inverse u shaped relationship between a pollutant and economic activity the dominant theoretical approach is given by integrated assessment modelling which consists of economic models that are combined with environmental impact models we critically evaluate the aggregation model dynamics and calibration aspects and their implications for the validity of the results we then turn to a discussion of several important econometric problems that go almost unnoticed in the literature the most fundamental problems relate to nonlinear transformations of nonstationary regressors and in a nonstationary panel context to neglected cross sectional dependence we discuss the implications of these two major and some minor problems that arise in the econometric analysis of kuznets curves our discussion shows that ekc modelling as performed to date is subject to major drawbacks at both the theoretical and the econometric level

choosing the competition and patent licensing this article examines licensing as a means of choosing the competitors which a patentee monopolist will face in the period after the patent expires the queue of entrants consists of two firms which differ in their relative strengths as competitors for example by size or level of marginal cost by structuring the industry to be composed of weak competitors the incumbent is able to prolong its dominant position in the industry after the patent expires examples are presented in which the evidence suggests that choosing the competition was an important motivation of the licensor s behavior

the perception and measurement of transaction costs the chapter discusses various explanations of how transaction cost minimising corporate configurations come about it contrasts darwinian with rational explanations finding both unsatisfactory what matters rather than computation of fully recognised transaction costs are managerial perceptions of transaction costs these perceptions are not expressed in numbers but in language this is related to arguments derived from bounded rationality and from transaction cost economics the chapter argues that issues of managerial perception must become central to analysis existing academic traditions which accord primacy to perception and to language are drawn upon and argued to be of great relevance to future work

is it a car or a truck managerial beliefs the choice of product architecture and the emergence of the minivan market segment new markets segments are a common setting for studies in technology strategy these studies generally assume that new segments already exist or have formed following the introduction of a product innovation by an entering firm thus theory on the role of established firms in the emergence of new market segments is underdeveloped this study informs current research by explaining the product innovation decisions of established firms during the emergence of a new market segment the results of a case study on the development and commercialization of the minivan at chrysler ford and general motors between 1970 and 1985 indicate that existing theories based on managerial cognition firm capabilities economic incentives and organizational structure are insufficient to explain the decisions this article develops theory based on the interrelationship of these four mechanisms

defending marshall s masterpiece ralph souter s critique of robbins essay we examine ralph w souter s defence in the 1930s of marshall s principles against robbins attempt to recast economics as a purely formal science of implications souter elaborated on marshall s invocations progressively to increase the realism of economic science and contrasted this perspective on marshall with robbins atomistic bias neglect of historical time and irreversibilities arbitrary restrictions on the scope of economic science and emphasis on logical and mathematical form over content souter demonstrates that robbins takes a walrasian inspired perspective on marshall s equilibrium concept whereas the authentically marshallian equilibrium notion generally incorporates potential for endogenous change on this and other matters souter has doctrinal priority in drawing attention to marshall s incipient evolutionary economics

innovation and the persistence of monopoly abstract the auction framework enables us to highlight a crucial feature of many r d races the losing firm can recoup part but not the entirety of its r d investments this feature is shown to account for the marked differences in results obtained by gilbert and newbery and by reinganum when the firm investing the largest amount wins with certainty we establish the existence of a unique equilibrium neither firm employs a pure strategy and the incumbent wins more often than the challenger

the benefits of privatization evidence from mexico critics of privatization often argue that its benefits come at a high cost to society the authors test the validity of this criticism for mexico s privatization program one of the world s largest case by case programs assessing the performance of newly privatized firms in such areas as profitability and efficiency they find that these firms quickly close the gap with their peers in the private sector their findings suggest that the firms profit gains come from productivity gains 52 percent layoffs 33 percent and higher prices 15 percent

the differential impact of uncertainty on investment in small and large businesses we study the impact of profit uncertainty on investment and whether or not this response is different in industries that are dominated by small firms versus those that are dominated by relatively larger firms our key findings are that the sign of the investment uncertainty relationship is negative and that the quantitative negative impact is substantially greater in industries dominated by small firms these results are robust to accounting for potential endogeneity of the uncertainty measure alternate procedures for measuring uncertainty and alternate ways of segmenting industries into small and large firm groups

regulation innovation and the introduction of new telecommunications services i examine the effects of fcc regulation on the innovation and introduction of advanced telecommunications services in the united states an interim of lighter regulation provides an experiment to test the regulatory regime s impact the econometric model comprises an arrival process for service innovation followed by a duration process for regulatory delay the number of services the firms created during the interim is 60 99 higher than the model predicts they would have created if the stricter regulation had still been in place overall firms would have introduced 62 more services to consumers during the study period if the regulation had not been in place

income growth and atmospheric pollution in spain an input output approach abstract the relationships between economic growth and environmental pressures are complex since the early nineties the debate on these relationships has been strongly influenced by the environmental kuznets curve hypothesis which states that during the first stage of economic development environmental pressures increase as per capita income increases but once a critical turning point has been reached these pressures diminish as income levels continue to increase however to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in spain the aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in spain in order to obtain empirical outcomes for this analysis we adopt an input output approach and use namea data for the nine pollutants first we undertake a structural decomposition analysis for the period 1995 2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions and second we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure

persistence of innovation in dutch manufacturing is it spurious this paper studies the persistence of innovation and the dynamics of innovation output in dutch manufacturing using firm data from three waves of the community innovation surveys cis pertaining to the periods 1994 1996 1996 1998 and 1998 2000 we estimate by maximum likelihood a dynamic panel data type 2 tobit model accounting for individual effects and handling the initial conditions problem we find that there is no evidence of true persistence in achieving technological product or process innovations while past shares of innovative sales condition albeit to a small extent current shares of innovative sales

agency costs and innovation abstract stylized facts indicate that small firms are responsible for a disproportionate share of innovative research there are many possible explanations for this fact the paper seeks to understand this phenomenon as the outcome of an optimal assignment of tasks across individuals and organizations it is shown that incentive costs associated with a given task depend on the total portfolio of tasks that an individual or an organization undertakes mixing hard to measure activities innovation with easy to measure activities routine is particularly costly since it will either lead to misallocation of attention across tasks or to misallocation of risk larger firms are at a comparative disadvantage in conducting highly innovative research because of the costs associated with managing a heterogeneous set of tasks it is further argued that optimal organizational responses to coordination and control of routine tasks will lead to bureaucratization within the firm and to financial constraints imposed by capital markets both of which are hostile to innovation

a review of the value of aggregators in electricity systems abstract distributed energy resources ders are being adopted throughout the world aggregators are lauded by some as critical in enabling ders to provide these valuable electricity services at scale in this light regulatory and policy bodies are discussing the role of aggregators and even the need to support their market entry in order to shed light on the economically efficient regulation of aggregators in electricity systems this paper systematically assesses the economic fundamentals of aggregators we perform a critical review of the value of aggregators defining the factors that determine their role in power systems under different technological and regulatory scenarios we identify three categories of value that aggregators may create fundamental transitory and opportunistic fundamental value is intrinsic to aggregation and is independent of the market or regulatory context transitory value can be significant in the near term but may be diminished by technological or regulatory advances finally opportunistic value emerges as a result of regulatory or market design flaws and may endanger the economic efficiency of the power system this paper provides a template for regulators to encourage the efficient development of aggregators while eliminating the potential for economic inefficiencies through opportunistic aggregation

challenges for r d and innovation in energy abstract in recent years there has been a growing interest in the role of r d and innovation in energy efficiency and dealing with climate change to improve our knowledge in these matters a workshop was organized in barcelona spain in january 2014 this introduction to the special issue first presents some insights from the literature on challenges for r d and innovation in energy the second section summarises the articles from this workshop that make up this special issue and that provide new insights into innovation in energy all the articles include energy policy recommendations based on the empirical analyses carried out

invention and innovation under alternative market structures the case of natural resources this paper examines the interactions between market structure and resource allocation over time when there is endogenous technical progress the structures considered are a planned economy pure monopoly and competition with patent rights in an efficient allocation the date of invention coincides with the date of innovation the date at which technology is used this is also true with a pure monopoly but monopoly retards technical progress relative to the efficient level competition for patents rights to a new technology results in excessively rapid technical progress if the resource endowment of the economy is sufficiently large also competition may lead to sleeping patents where invention strictly precedes the date of innovation

price cap regulation and technical change abstract existing analyses of the implications of price cap regulation for the development of cost reducing technologies assume that all r d is done by the regulated industry this is unrealistic we present a simple model of non cooperative r d by a regulated firm and a single external developer under a price cap regime of the sort characterised by cabral and riordan in equilibrium the external developer exerts less r d than is socially optimal the regulated firm may exert more or less a tightening of the regulatory regime impacts the r d incentives of both players though in different ways the optimal regulatory adjustment parameter may be bigger or smaller than that suggested by existing studies despite the scope for duplication of results research by an outsider necessarily enhances welfare

deregulation market competition and innovation of utilities evidence from japanese electric sector this paper explores the determinants of electric utility innovation and examines the impact of electric sector deregulation and market competition on it using a balanced panel database of nine japanese utilities from 1978 to 2014 both input r d expenditure and output patent application number and patent quality aspects of innovations are examined the empirical results indicate that deregulation and market competition decrease the former but increase the latter these results are followed by a discussion on why this scenario occurs the results also suggest that after deregulation utilities focus more on short term business oriented r d projects hence we call for governments to support long term public oriented and environmental research in the electric sector

globalisation and sustainability environmental kuznets curve and the wto abstract economic globalisation is seen by many as a driving force for global economic growth yet opinion is divided about the benefits of this process as highlighted by the wto meeting in seattle in late 1999 proponents of economic globalisation view it as a positive force for environmental improvement and as a major factor increasing the likelihood of sustainable development through its likely boost to global investment these proponents mostly appeal to analysis based on the environmental kuznets curve ekc to support their views about environmental improvement but ekc analysis has significant deficiencies furthermore it is impossible to be confident that the process of economic globalisation will result in sustainable development if weak conditions only are satisfied strong conditions probably need to be satisfied to achieve sustainable development and given current global institutional arrangements these are likely to be violated by the economic globalisation process global political action seems to be needed to avert a deterioration in the global environment and to prevent unsustainability of development this exposition demonstrates the limitations of ekc analysis identifies positive and negative effects of economic globalisation on pollution levels and highlights connections between globalisation and the debate about whether strong or weak conditions are required for sustainable development the article concludes with a short discussion of the position of wto in relation to trade and the environment and the seemingly de facto endorsement of wto of weak conditions for sustainable development it suggests that wto s relative neglect of environmental concerns is no longer politically tenable and needs to be reassessed in the light of recent developments in economic analysis the skew of economic growth e g in favour of developing countries is shown to be extremely important from a global environmental perspective

the history of the theory of the firm from marshall to robinson and chamberlin the source of positivism in economics a widely believed story in the folklore of the economics profession is that the theories of perfect competition and monopoly were well established from the time of marshall or perhaps pigou s economics of welfare and that the role of imperfect or monopolistic competition theory was to fill in the middle ground between these extremes it will be shown in this paper that the folklore conflicts with the historical evidence robinson and chamberlin created the theory of perfect competition in the course of inventing imperfect and monopolistic competition theory robinson and chamberlin between them were concerned with the same issues that concerned marshall the difference is that robinson and chamberlin derived their analyses from a few clear axioms while marshall sought to develop his analysis from a well informed but necessarily impressionistic description of actual business behaviour and dynamic processes along with the introduction of indifference analysis to english speaking economists by hicks and allen robinson and chamberlin gave the theory of value and distribution a complete and logically consistent axiomatic basis because their axioms relating to business motivation and behaviour were amenable to empirical verification the work of robinson and chamberlin rendered the theory of value and distribution open to a new empirical criticism it will be argued that the widespread acceptance of friedman s 195 3 positive methodological position was a necessary response to these empirical criticisms if the new axiomatic foundations of the theory of value and distribution were to be as secure as those previously provided by marshall

strategic behaviour of incumbent firms in the uk abstract the main purpose of this paper is to examine the incidence of strategic behaviour in the uk by means of a questionnaire study performed across three broad manufacturing industries food electrical engineering and chemicals of the strategies which have received substantial theoretical attention r d and advertising appear widely used patenting pricing and excess capacity much less so vertical instruments such as purchasing policy also stand out as important but possibly only a minority of firms in our sample actively pursue strategic instruments

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

differences in the rates of return to r d for european and us young leading r d firms this paper examines the sources of europe s lagging business r d performance relative to the us particularly the role played by missing young leading innovators in high technology intensive sectors in europe it investigates through econometric analysis differences in the rates of return to r d of european and us large r d firms it finds that while in the us young firms succeed in realizing significantly higher rates of return to r d as compared to their older counterparts including in high tech sectors european firms fail to generate significant rates of return even if they are yollies and even if they are in high tech sectors these findings can at least partly explain why europe has less r d intensive young leading innovators in high technology intensive sectors

total factor productivity and the environmental kuznets curve abstract empirical studies support the environmental kuznets curve hypothesis ekc for some pollutants as income increases pollution increases reaches a peak and eventually decreases while relying mostly on cross sectional data the interpretations assert that the ekc is a by product of economic growth over time in doing so and in neglecting the role of important country specific characteristics these studies overlook potential econometric problems and introduce policy misconceptions differences in total factor productivity tfps account for much of the variation in income across countries with important implications for environmental quality we develop a theoretical model where different tfps produce a cross sectional ekc even if the dynamic path of environmental quality to its steady state in individual countries suggest otherwise the cross sectional ekc depends on diminishing returns to scale in environmental protection on the curvatures of the utility function with respect to consumption and of the environmental protection function and the elasticities of steady state consumption and environmental expenditures with respect to variation in tfps

takeover threats and managerial myopia this paper examines the familiar argument that takeover pressure can be damaging because it leads managers to sacrifice long term interests in order to boost current profits if stockholders are imperfectly informed temporarily low earnings may cause the stock to become undervalued increasing the likelihood of a takeover at an unfavorable price hence the managerial concern with current bottom line the magnitude of the problem depends on a variety of factors including the attitudes and beliefs of shareholders the extent to which corporate raiders have inside information and the degree to which managers are concerned with retaining control of their firms

production experiences and market structure in r d competition abstract in the rd and ii the likelihood of persistent leadership increases with the value of being the winner and the value of being a loser but decreases with expected waiting time of r d innovation and the flow of monopoly profits however destructive innovations may still occur even when production experiences are allowed to play an important role in the r d competition

second mover advantages in the strategic adoption of new technology under uncertainty abstract this paper introduces technological uncertainty into a timing game of new technology adoption it is shown that the timing neither necessarily involves first mover advantages in precommitment equilibria reinganum review of economic studies xlviii 1981 395 405 nor rent equalization due to the threat of preemption fudenberg and tirole review of economic studies lii 1985 383 401 rather there may be second mover advantages because of informational spillovers furthermore the model predicts that the equilibrium payoffs will typically be discontinuous and non monotonic in the probability that the new technology is profitable a welfare analysis reveals several market failures and suggests that policy intervention should adequately depend on the nature of uncertainty and the rate of technological progress

the environmental kuznets curve when the environment exhibits hysteresis abstract the relevance and implications of the environmental kuznets hypothesis are examined in the presence of stock effects and non linearities associated with pollution generation stock effects lead to hysteresis and irreversibilities in environmental quality that are overlooked when emphasis is placed on the flow effects of pollutants only it is demonstrated here that an optimal growth plan in the presence of stock effects shifts the focus away from prescribing economic growth as a panacea for environmental ills implications for currently industrializing economies are discussed

nonlinearities and heterogeneity in environmental quality an empirical analysis of deforestation we use a panel data set of 59 developing countries over the 1972 1994 period to study the deforestation process relying on both parametric and semiparametric models we examine nonlinearities and heterogeneity in the deforestation process we first study the existence of an environmental kuznets curve ekc and then analyze determinants of deforestation our data sample provides no evidence of an ekc we also find that political institution failures may worsen the deforestation process in developing countries

growth and the environment are we looking at the right data abstract time series evidence on growth and the environment suggests an environmental kuznets curve ekc whereas longitudinal studies fail to produce robust estimates for the ekc this paper offers a theoretical explanation for these apparently contradicting findings and theoretical guidance for future empirical work

does firm size matter evidence on the impact of liquidity constraints on firm investment behavior in germany abstract this paper examines the link between liquidity constraints and investment behavior for german firms of different sizes from 1970 to 1986 results indicate that medium sized firms appear to be more liquidity constrained in their investment behavior than either the smallest or largest firms in the study suggesting that the unique german infrastructure designed to assist the small firm has indeed succeeded in alleviating to some degree such liquidity constraints findings also support the hypothesis that the emerging competition and internationalism which characterized the german financial markets in the 1980s have been improving access to capital for some groups of firms

review of proposals for practical power sector restructuring and reforms in a dynamic electricity supply industry abstract south africa s electricity supply industry esi remains a vertically integrated monopoly despite global trends towards restructuring the monopolistic nature of the esi could hinder the development of distributed power systems as penetration of renewable electricity increases the research aims to rationalise south africa s esi evolution propose practical power sector restructuring in the short to medium term and to determine their potential impact the research methodology included a single case study instrument with embedded sub units of analysis primary research data was gathered using semi structured interviews with industry experts in addition to which secondary data from government documents and archival records were used for triangulation research results conclude that south africa s esi grew due to techno economic industrialisation factors while apartheid era policies influenced the esi in only some specific respects the vertically integrated status quo was sustained in the post transformation period due to government s focus on social imperatives lack of regulatory policy certainty and conflicts in political ideology south africa did not experience the pre conditions that triggered global power sector reforms in the late 20 th century but these pre conditions are now becoming evident privatisation of eskom generation and introduction of wholesale and retail competition are not practical in the short to medium term proving the infeasibility of the standard model of reform locally the introduction of an independent system and market operator ismo using a single buyer model is seen as the most favourable and practical option with the ismo owning transmission infrastructure the research suggests that esi changes will increase system efficiencies economic performance and private sector involvement but will not reduce electricity tariffs the scenarios challenges and proposals identified in this research are also applicable to other countries in africa and other developing regions of the world that have similar social and political backgrounds ensuring sustainable supply of electricity

monopoly incentives for cost reducing r d abstract it is shown in this paper that there exist cost innovations for which a monopolist has a higher incentive to invest than a social planner this unveils the limits of the claim based on arrow 1959 that a monopoly always has a lower incentive to innovate than a social planner and therefore than is socially desirable in contrast to previous results the comparison of incentives may also depend upon the demand function finally for a restricted domain of analysis a rule for comparing the monopoly and the social planner incentives is derived

and the winner is acquired entrepreneurship as a contest yielding radical innovations new entrants to a market tend to be superior to incumbents in originating radical innovations we provide a new explanation for this phenomenon based on markets for technology it applies in industries where successful entrepreneurial firms or their technologies are acquired by incumbents that then commercialize the innovation to this end we analyze an innovation game between one incumbent and a large number of entrants in the first stage firms compete to develop innovations of high quality they do so by choosing at equal cost the success probability of their rd the bigger the number of entrants the more radical the most radical project generally entrants tend to choose more radical r d approaches and generate the highest value innovation in case of success we illustrate our theoretical findings by a qualitative empirical study of the electronic design automation industry and derive implications for research and management

asymmetric information and the new theory of the firm financial constraints and risk behavior this paper summarizes recent developments in the theory of the firm that have arisen in examining the implications of imperfect information it shows that a wide range of these models have similar implications for the likely reaction of firms to external environmental and policy changes two significant implications are 1 that firms behave as if they are risk averse individuals maximizing a utility function of terminal wealth profitability even when the risks involved are unsystematic and 2 in many circumstances because this utility function is likely to be characterized by decreasing absolute risk aversion firms are likely to respond significantly and positively to changes in cash flow and profitability together these two phenomena are able to account for a wide range of firm behaviors that have been empirically observed both formally and informally and that are difficult to explain in terms of the traditional theory of the firm furthermore the responses of such firms to policy interventions are likely to differ significantly from those of neoclassical firms this abstract was borrowed from another version of this item

analyzing literature based innovation output indicators the italian experience abstract this paper presents the results of a study on the product innovations introduced in the italian market in 1989 and reported in a selected number of trade journals the analysis of data collected by means of this literature based counting procedure confirms that r d oriented industries and large firms do not in italy have a marked competitive advantage in innovation the country appears to be instead characterized by a significant presence of consumer goods industries and small firms in innovation our data indicate a statistically significant association between trade competitiveness and strength in product innovation and show the comparatively higher capacity for product innovation of some of the industries in which italy achieves a positive performance in international trade moreover the presence of spillovers at the regional level from both private and public r d expenditures proves to be positively correlated with the development of product innovations finally small firms with fewer than 50 employees appear to be more innovative than is usually believed to be the case

energy consumption income and carbon emissions in the united states abstract this paper investigates the effect of energy consumption and output on carbon emissions in the united states earlier research focused on testing the existence and or shape of an environmental kuznets curve without taking energy consumption into account we investigate the granger causality relationship between income energy consumption and carbon emissions including labor and gross fixed capital formation in the model we find that income does not granger cause carbon emissions in the us in the long run but energy use does hence income growth by itself may not become a solution to environmental problems

licensees as entry barriers in a more general setting than has been considered hitherto this paper examines how the incumbent in a market threatened by entry can exploit its first mover advantage by licensing its technology not to a potential entrant but to firms that would have remained outside the industry it is shown among other things that the incumbent may subsidize the variable costs of its licensees in order to deter entry even when entry is not deterred it is demonstrated that the incumbent might opt to invite outsiders as licensees

managerial incentives and capital management the paper shows how career concerns rather than effort aversion can induce a natural incongruity in risk preferences between managers and superiors a model based on learning about managerial talent is developed to study second best contractual remedies we show that the optimal wage contract is an option of the value of the manager s human capital for insurance reasons and that consequently rationing of capital is often required to counterbalance the manager s resulting incentive to overinvest rationing is strictly superior to price decentralization offering one reason for the prevalence of centralized capital budgeting procedures

intellectual property rights and the mode of technology transfer abstract transferring technology in an environment where patent protection is uncertain can pose significant risks to an innovating firm s ability to appropriate rents this paper incorporates asymmetric information in a screening game where the innovating firm has the choices of licensing a new product at arm s length to a foreign firm exporting it or licensing it to a subsidiary subsidiary production avoids the risk of imitation but involves higher costs for the innovating firm the gains to the southern country from the lack of intellectual property right protection may be offset by strategic behavior by northern firms who opt for technology transfer via subsidiary or monopoly production

the mecca of alfred marshall alfred marshall is often quoted for his statement that the mecca of the economist lies in economic biology and he is seen as a father of evolutionary economics however the limited character of his evolutionary theory and its close resemblance to t he ideas of herbert spencer are sometimes misunderstood or ignored th e argument in this paper is that marshall saw the value of the biologi cal metaphor for economics but in part the spencerian influence thwarted the development of an adequate evolutionary analysis copyright 1993 by royal economic society
