pushing the boundaries of climate economics critical issues to consider in climate policy analysis abstract climate policy choices are influenced by the economics literature which analyses the costs and benefits of alternative strategies for climate action this literature in turn rests on a series of choices about the values and assumptions underlying the economic analysis the methodologies for treating dynamics technological change risk and uncertainty and the assumed interactions between economic systems society and the environment including institutional constraints on climate policy we identify and discuss such critical issues pushing at the boundaries of current climate economics research new thinking in this area is gathering pace in response to the limitations of traditional economic approaches and their assumptions on economic behaviour ecological properties and socio technical responses we place a particular emphasis on the role of induced technological change and institutional setups in shaping cost effective climate action that also promotes economic development and the alleviation of poverty

modelling the redirection of technical change the pitfalls of incorporeal visions of the economy this paper discusses attempts to represent the role of r d in the transition towards a low carbon economy through models with no meaningful granularity to inform the studied phenomenon by means of a critical analysis of acemoglu et al 2012 we show that the advantage of these models their analytical tractability does not make up for their disadvantages lack of control over policy implications and questionable numerical results on the one hand a comprehensive analysis of the results of acemoglu et al 2012 shows that even research subsidies do not pave the way for ambitious climate policies with low transitory costs thus contradicting their policy message on the other hand critical parameters such as the elasticity of substitution between clean and dirty technologies carbon sinks or the productivity of researchers are not in accordance with existing scientific knowledge we show that using more realistic parameters leads to even more pessimistic conclusions and that their model provides no leeway for overcoming them we suggest that a too highly aggregated model can only describe an incorporeal economy and comes to a deadlock we propose a more promising route for economic research in order to break this deadlock

market share market value and innovation in a panel of british manufacturing firms this paper examines the empirical relationship between technological innovations market share and stock market value new developments in the estimation of dynamic count data models are used to control for unobserved firm specific heterogeneity we find a robust and positive effect of market share on observable headcounts of innovations and patents although increased product market competition in the industry tends to stimulate innovative activity furthermore the impact of innovation on market value is larger for firms with higher market shares we argue that our results are consistent with models where high market share firms have incentives to pre emptively innovate

the use and impact of business advice by smes in britain an empirical assessment using logit and ordered logit models this study assesses the effect of differences in types of client on the use and impact of business advice by smes in britain using new survey evidence from the cambridge esrc centre for business research survey of 1997 the survey covering over 2500 respondents is the largest and most definitive assessment available in britain moreover the survey allows an assessment of the full range of providers of external advice the private sector business associations and various public sector bodies as well as the fields of advice using multivariate logit models it is found that size of firm rate of growth and innovation appear to be the main variables influencing the likelihood of firms seeking external advice both from different sources and from different fields other variables which are investigated include age profitability skill levels manufacturer services and exporter nonexporter ordered logit models of the impact of the advice demonstrate that there are significant differences between client

welfare specifications and optimal control of climate change an application of fund the sensitivity of the optimal control of carbon dioxide emissions to the specification of the social welfare function is systematically explored using the fund model increasing risk aversion emphasises climate change damages relative to emission reduction costs but at the same time increases the discount rate of consumption without international co operation the discount rate effect dominates so that optimal control decreases with increasing risk aversion with international co operation optimal control first increases then decreases with increasing risk aversion since climate change falls heaviest on the poor optimal control increases with increasing inequity aversion full fledged intergenerational welfare functions on the one hand emphasise climate change damages but on the other hand place more weight on current poorer generations in fund the two tendencies almost cancel

the induced innovation hypothesis and energy saving technological change we develop a methodology for testing hicks s induced innovation hypothesis by estimating a product characteristics model of energy using consumer durables augmenting the hypothesis to allow for the ine uence of government regulations for the products we explored the evidence suggests that i the rate of overall innovation was independent of energy prices and regulations ii the direction of innovation was responsive to energy price changes for some products but not for others iii energy price changes induced changes in the subset of technically feasible models that were offered for sale iv this responsiveness increased substantially during the period after energy efficiency product labeling was required and v nonetheless a sizable portion of efficiency improvements were autonomous

the energy efficiency paradox revisited through a partial observability approach the present paper examines the energy efficiency paradox demonstrated in greek manufacturing firms through a partial observability approach the data set used has resulted from a survey carried out among 161 energy saving technology firm adopters maximum likelihood estimates that arise from an incidental truncation model reveal that the adoption of the energy saving technologies is indeed strongly correlated to the returns of assets that are required in order to undertake the corresponding investments the source of the energy efficiency paradox lies within a wide range of factors policy schemes that aim to increase the adoption rate of energy saving technologies within the field of manufacturing are significantly affected by differences in the size of firms finally mixed policies seem to be more effective than policies that are only capital subsidy or regulation oriented

sme growth the relationship with business advice and external collaboration the paper presents multivariate analysis of the relationship of sme growth with the acquisition of external business advice whilst controlling for the influence of sme characteristics of age manufacturing services high technology innovator level of skill of the workforce exporter and number of competitors the relationship of external business advice with sme performance is statistically significant for only a small number of sources and fields obtaining external advice in fields such as business strategy and staff recruitment is associated with positive firm performance the main positive relationships of advice and performance are dominated by private sector sources such as lawyers suppliers customers and business friends relatives collaborative arrangements with suppliers nationally internationally have a strong positive relationship with employment and turnover growth collaboration with local suppliers has a strong positive relationship with growth in profitability there is little evidence of statistically significant relationships between government backed providers of business advice such as business link and firm performance

are the economic costs of stabilising the atmosphere prohibitive abstract macro economic studies of the costs of reducing co2 emissions generally estimate the global cost of stabilising the atmospheric concentrations of co2 in the range 350 550 ppm in trillions of usd this creates the impression that the cost of co2 reductions is so large that it threatens economic development but presented in another way a completely different picture emerges there is widespread agreement amongst the more pessimistic macro economic studies that stringent carbon controls are compatible with a significant increase in global and regional economic welfare even if the cost of co2 abatement rises to 5 of global income per year by the end of this century this reduction is minor compared with the tenfold increase in global income that is expected since income is assumed to grow by a couple of percent per year the trillion usd cost could also be expressed as a few years delay in achieving an order of magnitude higher income levels similar observations can also be made as regards near term abatement targets such as the kyoto protocol a more widespread recognition of the fact that carbon abatement policies will only marginally affect economic growth is likely to increase the willingness to introduce carbon abatement policies

determinants of the incidence and scale of seed capital investments by venture capital firms employing both behavioral decision making and agency theories our study seeks to identify those factors that influence a venture capital vc firm s decision to undertake seed capital investments and subsequently the scale of such activity using data on the investments made by 2949 vc funds raised worldwide between 1962 and 2002 we find investor age timing of investment and fund location to be of importance in addition the size of the fund and the existing number of portfolio firms exert opposite influences on the level of seed capital activity of the vc firm these results suggest that seed activity is a valuable source of market intelligence for leading vc firms seeking proactively to identify and invest in novel technologies

technology imports and r d efforts of korean manufacturing firms abstract this paper analyzes the relationship between technology imports and r d efforts of korean manufacturing firms by a two stage method in the first stage using a sample representing the whole population of firms the paper shows that firms importing technology tend to commit themselves to r d efforts through having formal r d institutes in the second stage it shows that among firms with formal r d institutes technology imports have non complementary relationship with r d efforts moreover when technology imports are considered interactively with international inventive activity they turn out to have rather a substitutive relationship with r d efforts

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

employment change in independent owner managed high technology firms in great britain there is a growing volume of literature that points to the potential for small technology based firms to achieve substantial employment growth as a direct consequence of such work this sector of any economy has attracted increasing attention from national and local governments concerned with finding ways of revitalising economically deprived localities and creating employment opportunities this paper provides up to date empirical evidence surrounding the ability of small high technology firms to create additional jobs in great britain in addition key founder and business characteristics are isolated which are significantly associated with employment change in growing high technology firms over the 1986 to 1992 period with respect to factors influencing these high levels of employment growth a high firm size in 1986 was found to act positively on employment growth as was a graduate level education for the key founder on the finance side firms which had access to and used a multiplicity of sources of start up finance tended to grow faster futher on the basis of our results we would suggest and recommend a government policy which at the firm level actively encourages high technology firm start ups who record higher rates of survival than firms in more conventional sectors as well as providing support for existing high technology firms who have already demonstrated the inclination and ability to grow in employment size

gasoline demand revisited an international meta analysis of elasticities meta analysis is used to determine if there are factors that systematically affect price and income elasticity estimates in studies of gasoline demand four econometric models are estimated using long run and short run price and income elasticity estimates from previous studies as the dependent variables explanatory variables include functional form lag structure time span national setting estimation technique and other features of the model structure elasticity estimates are found to be sensitive to the inclusion or exclusion of some measure of vehicle ownership static models appear to overestimate short run elasticities underestimate long run price elasticities but pick up the full long run income responsiveness there is variation in the elasticity of demand across countries especially in the short run and gasoline demand appears to be getting more price elastic and less income elastic over time

finance for smes a u k perspective this paper provide an overview of recent trends in the financing of smaller businesses in the u k it refers in particular to the findings of a major recent programme of work in this area funded by the economic and social research council in which the author participated this programme included the first national survey to address these issues since the bolton report of 1971 as well as a range of projects covering the finance of ethnic businesses and hi tech firms as well as the market for informal venture capital on the basis of this work and of the results of more recent follow up surveyors it is concluded that the evidence for general equity or debt gaps in the u k is weak if anything sme funding was too easy in the boom of the late 1980s it is argued that consideration could be given to the promotion through seedcorn funding of sme co operative or mutual guarantee schemes to reduce information asymmetry in u k credit markets

the transition from dirty to clean industries optimal fiscal policy and the environmental kuznets curve abstract this paper investigates privately and socially optimal patterns of economic development in a two sector endogenous growth model with clean and dirty goods we consider a second best fiscal policy framework in which distortionary taxes jointly influence economic growth and environmental quality in this policy setting three conditions produce an environmental kuznets curve ekc i dirty output is bounded ii clean output grows endogenously and iii growth in the dirty sector reduces growth in the clean sector these conditions do not arise with a consumption externality but can emerge with a production externality endogenous labor supply implications are also investigated although not necessary for producing an ekc endogenous labor supply provides additional linkages that produce an ekc under circumstances in which it would otherwise not appear

sustainable development with extractive and non extractive use of the environment in production this paper considers an economy in which the environment plays a role both in welfare and production an endogenous growth model which allows for abatement activities is formulated in order to study the impact of pollution on welfare and long term growth conditions for optimal and balanced economic growth are discussed and a numerical example is given to provide some insight in the mechanisms at work in the model

a model of technological breakthrough in the renewable energy sector abstract models with induced technological change in the energy sector often predict a gradual expansion of renewable energies and a substantial share of fossil fuels remaining in the energy mix through the end of our century however there are historical examples where new products or technologies expanded rapidly and achieved a high output in a relatively short period of time this paper explores the possibility of a technological breakthrough in the renewable energy sector using a partial equilibrium model of energy generation with endogenous r d our results indicate that due to increasing returns to scale a multiplicity of equilibria can arise in the model two stable states can coexist one characterized by a lower and one by higher supply of renewable energy the transition from the low output to the high output equilibrium is characterized by a discontinuous rise in r d activity and capacity investments in the renewable energy sector the transition can be triggered by a rise in world energy demand by a drop in the supply of fossil fuels or by policy intervention under market conditions the transition occurs later than in the social optimum hence we identify a market failure related to path dependence and technological lock in that can justify a strong policy intervention initially paradoxically well intended energy saving policies can actually lead to higher emissions as they reduce the incentives to invest in renewable energies by having a cushioning effect on the energy price hence these policies should be supplemented by other instruments that restore the incentives to invest in renewable energies finally we discuss the influence of monopoly power in the market for innovations we show that market power can alleviate the problem of technological lock in but creates a new market failure that reduces static efficiency

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

rebound directed technological change and aggregate demand for energy abstract we analyse the long run role of energy in aggregate production the factor share of energy has been remarkably constant despite the relative decline in the price of energy we analyse possible explanations for this observation ruling out the idea that endogenous directed technological change has led to a failure of energy augmenting technology to keep pace with labour augmenting technology instead we propose a model in which a combination of income and substitution effects has driven both shifts in consumption patterns towards existing energy intensive goods and the emergence of new such goods

the eclectic paradigm of international production a restatement and some possible extensions this article reviews some of the criticisms directed towards the eclectic paradigm of international production over the past decade and restates its main tenets the second part of the article considers a number of possible extensions of the paradigm and concludes by asserting that it remains a robust general framework for explaining and analysing not only the economic rationale of economic production but many organisational and impact issues in relation to mne activity as well

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

generational welfare under a climate change policy with induced innovation we develop a climate economy model with generational heterogeneity and the potential for climate policy induced technological change we use the model to assess the distributional implications of climate policies and of policy designs which recycle generated revenues to finance research and development r d we model only innovation in the energy generated per unit of fossil fuels so the quantitative results we derive are small our emphasis is on the distributional impacts of redistributing climate policy rents to enhance r d we show that while investments of climate policy rents to accelerate innovation are likely to be welfare improving as long as significant market failures exist they are also likely to exacerbate the distributional inequities created across generations by climate change policies the political feasibility of climate policies may be harmed by rent transfers to r d as these transfers can increase the costs borne by agents alive today while increasing benefits to generations born far into the future

are the economic costs of non stabilising the atmosphere prohibitive a comment in a recent paper in this journal azar and schneider present carbon abatement costs as a few years delay in an increasing path of welfare and they suggest the adoption of stricter abatement policies to avoid climate change we show that the same argument can be used to derive the opposite conclusion in most studies not only abatement costs but also climate change costs represent a small loss in future welfare the reason for this is the implicit assumption of perfect long term substitutability between man made and environmental goods that many of these models adopt we argue that instead of downplaying the costs of abatement measures we should try to better understand the substitutability possibilities between man made and environmental goods that is the character of long term costs of climate change

changing use of external business advice and government supports by smes in the 1990s bennett r j and robson p j a 2003 changing use of external business advice and government supports by smes in the 1990s reg studies 37 795 811 this paper uses cross sectional surveys of 1991 and 1997 a panel survey of firms surviving between 1991 and 1997 and comparison with a further cross sectional survey in 1999 to compare the levels of use by smes of external business advice the resource based theory of the firm indicates that smes seek advice in order to increase their competitive capacity over time increasing competition between smes is expected to lead to increasing use of advice however the paper demonstrates that only modest changes over time have occurred in aggregate use of external advice by smes and these are not statistically significant this suggests that earlier growth in external business advice services may now have plateaued there are some significant changes of use by source increasing for advertising personnel and recruitment new technology and computer servic

economic growth international competitiveness and environmental protection r d and innovation strategies with the warm model abstract it is often argued that policies designed to protect the environment may harm economic growth moreover if introduced unilaterally by a given country they may reduce the competitiveness of domestic firms these arguments are generally based on the assumption that environmental protection has to be achieved through the introduction of emission charges e g a carbon tax however three issues need to be raised first the tax is not the only policy instrument and is not the most efficient one that can be used to reduce polluting emissions secondly even when a tax policy is implemented it is important to assess the feedback effects induced by recycling the tax revenue thirdly and most importantly the role of technical progress cannot be neglected therefore there may exist a policy mix that provides firms with the correct incentives to adopt energy saving technologies and to invest in environment friendly r d the first two issues have partly been explored both in the theoretical and empirical literature the third issue i e the role of incentives to technical progress still lacks adequate quantitative assessment this is why a new model has been developed which endogenizes technical progress and its effects and feedbacks on economic energy and environmental variables using warm an econometric general equilibrium model for the european union and for each member country this paper presents simulation results up to 2015 of the effects of some industrial environmental policies which are aimed at protecting the environment without necessarily damaging competitiveness and economic growth the results show that policies that stimulate environmental r d technological innovation and diffusion may provide firms with the correct incentives to avoid damaging the environment while preserving their competitiveness in the market moreover such a policy based both on r d subsidies and on innovation incentives may not worsen the public sector budget balance as a result of the positive effects on economic growth

internal and international migration in mexico 1995 2000 using micro data from mexico and us 2000 population censuses and following a multi choice variant of roy s 1951 model this article pools into one model the determinants of internal and international migration in mexico while paying explicit attention to the potential problem of self selection the results reveal that ignoring multiple destinations in the migration decision might lead to erroneous inferences about the determinants of migration and the type of selection after controlling for wage differences the results suggest that single adult men with low schooling levels tend to migrate to the us while married women and men with higher levels of schooling tend to migrate within mexico we also found that there are strong differences between domestic and international social networks

the informal venture capital market aspects of scale and market efficiency abstract risk capital is a resource essential to the formation and growth of entrepreneurial ventures in a society that is increasingly dependent upon innovation and entrepreneurship for its economic vitality the performance of the venture capital markets is a matter of fundamental concern to entrepreneurs venture investors and to public officials this article deals with the informal venture capital market the market in which entrepreneurs raise equity type financing from private investors business angels the informal venture capital market is virtually invisible and often misunderstood it is composed of a diverse and diffuse population of individuals of means many of whom have created their own successful ventures there are no directories of individual venture investors and no public records of their investment transactions consequently the informal venture capital market poses many unanswered questions the author discusses two aspects of the informal venture capital market questions of scale and market efficiency the discussion draws upon existing research to extract and synthesize data that provide a reasonable basis for inferences about scale and efficiency private venture investors tend to be self made individuals with substantial business and financial experience and with a net worth of 1 million or more the author estimates that the number of private venture investors in the united states is at least 250 000 of whom about 100 000 are active in any given year by providing seed capital for ventures that subsequently raise funds from professional venture investors or in the public equity markets and equity financing for privately held firms that are growing faster than internal cash flow can support private investors fill gaps in the institutional equity markets the author estimates that private investors manage a portfolio of venture investments aggregating in the neighborhood of 50 billion about twice the capital managed by professional venture investors by participating in smaller transactions private investors finance over five times as many entrepreneurs as professional venture investors 20 000 or more firms per year compared to two or three thousand the typical angel backed venture raises about 250 000 from three or more private investors despite the apparent scale of the informal venture capital market the author cites evidence that the market is relatively inefficient it is a market characterized by limited information about investors and investment opportunities furthermore many entrepreneurs and private investors are unfamiliar with the techniques of successful venture financing the author s scale and efficiency inferences coupled with evidence documenting gaps between private and social returns from innovation prompt questions about public as well as private initiatives to enhance the efficiency of the informal venture capital market the article concludes with a discussion of venture capital network inc vcn an experimental effort to enhance the efficiency of the informal venture capital market vcn s procedures and performance are described followed by a discussion of the lessons learned during the first two years of the experiment

climate policy and induced r d how great is the effect abstract carbon taxes or tradable permit systems to address climate change may induce research and development in energy related technologies we construct a single knowledge stock model of r d growth and climate to assess the importance of this effect the contribution of induced r d is shown to be very sensitive to i the duplication externality ii the feasibility of dedicated research subsidies to internalize inter firm knowledge spillovers iii the opportunity cost of r d iv the initial level of research expenditure and v the elasticity of substitution between energy and other factors of production in contrast the direction and scale of the inter temporal research spillover are of secondary importance we find strong support for rezai s 2011 argument that when the business as usual scenario no policy is modeled appropriately all externalities treated as external sacrifices for early generations associated with optimal climate policy are minor or non existent employing our preferred selections for the parameters we find that adding an induced r d component to the model increases the welfare impact of the first best policy optimally chosen carbon tax and research subsidies by an average value of more than 400 and of the second best policy carbon tax alone by approximately 22

estimating country specific environmental kuznets curves from panel data a bayesian shrinkage approach designing an efficient global climate policy turns out to be a difficult yet crucial task since there are noteworthy cross country differences in energy and carbon intensities in this article the environmental kuznets curve ekc hypothesis is tested for carbon dioxide co2 emissions and as a modelling technique the iterative bayesian shrinkage procedure is employed to handle the cross country differences the results suggest that first the ekc hypothesis is rejected for 47 out of the 51 countries considered when the heterogeneity in countries energy efficiencies and cross country differences in the co2 emissions trajectories are accounted for second a classification of the results with respect to the development levels of the countries concerned reveals that the emergence of an overall inverted u shaped curve is due to the fact that in high income countries increase in gross domestic product gdp decreases emissions while in low income countries emissions and gdp are positively correlated

transitional impacts of environmental policy in an endogenous growth model to explore the link between a tighter environmental policy and economic growth the authors employ an endogenous growth model with endogenous technological progress in abatement technologies the environment which is modelled as a renewable resource acts both as a public consumption good and as a public input into production the entire transition towards a new balanced growth path after a tightening of environmental policy is computed analytically the authors find sharp contrasts between short run and long run effects whereas the level and the growth rate of output may decline in the short run income growth may improve in the long run copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

funding for innovation in small firms the role of government abstract this paper examines some of the issues facing innovative small firms the shortage of enterprise funding for such small firms can be explained by the uncertainty associated with such ventures uncertainty which is magnified in the case of hightechnology firms we characterise the uncertainty as an information gap both technological and commercial which is exacerbated by an asymmetry of interest between the founders of a firm and private sector sources of finance we explore the sources of this uncertainty and examine the effect that one government scheme the small firms merit awards for research and technology smart has had in offsetting such problems some suggestions for improvements in policy in the light of the experience of smart are put forward

induced innovation and energy prices this paper uses u s patent data from 1970 to 1994 to study the impact of energy prices on energy efficient innovations theories of technological change have focused both on demand side factors which spur innovative activity by increasing the value of new innovations and supply side factors such as scientific advancements that make new innovations possible data on demand side factors are easily obtained but data on supply side factors that influence innovation are not readily available this paper uses patent citations as a measure of the usefulness of the existing base of scientific knowledge citations to previous patents are used to construct productivity estimates which measure the usefulness of the existing stock of knowledge to inventors in a given energy field for any given year these estimates are then combined with data on demand side factors to estimate a model of induced innovation in energy technologies the results indicate that both energy prices and the supply of knowledge have strongly significant positive effects on innovation the paper concludes with a discussion of the implication of this work for environmental policy

industrial strategy a missing link in british economic policy this paper critically analyzes the potential and limitations of economic instruments for environmental protection it presents a general framework for analyzing environmental issues along with a taxonomy for classifying different approaches to environmental protection a key contribution of the paper is to identify critical steps in marketing economic incentive approaches for environmental protection the challenge to researchers is to design tools that will help achieve environmental goals more effectively this means taking careful account of political technical and economic constraints in system design copyright 1993 by oxford university press

external ownership and innovation in the united kingdom this paper examines the impact of ownership and a variety of other variables on the likelihood of innovation and the presence of an r d function within a national sample of uk defence related firms it is shown that foreign ownership has a negative indirect impact upon innovation mixed support is found for the schumpeterian approach to innovation involvement in export markets technological opportunity and r d collaboration are shown to have a positive impact on innovation

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

environmental policy in the presence of induced technological change we examine the hypothesis that induced technological change itc can dramatically lower the cost of a carbon tax in a static optimal tax model the research and development sector is represented by an aggregate stock of energy saving technology which acts as a weak substitute with a polluting resource in the energy generation sector using this model we analytically show how itc occurs and affects the cost of a carbon tax applying quantitative estimates of the size of itc to numerical simulations calibrated to the us economy we find that existing empirical evidence can reduce the welfare cost of environmental tax reform by 12 our tests of alternative parameters show that this result is highly sensitive to the assumptions used suggesting that itc could result in much larger reductions in cost

government advice networks for smes an assessment of the influence of local context on business link use impact and satisfaction business link in britain is one of the main recent government initiatives to support smes in the eu the paper uses a 1997 survey of smes to determine how business link use impact and satisfaction are influenced by firm characteristics local partnership characteristics local geographical context service intensity and other explanatory variables the paper presents econometric estimates based on logit and ordered logit models a key finding of the paper is to demonstrate that local context is not very significant to service use impact or satisfaction but local business link management and adviser performance are important influences on the impact and satisfaction major differences in the way smes use government backed services are also found there are high volumes of use of gateway information services producing only low impact and low volumes but high impacts and satisfaction with intensive advice services governed by contracts between the clients and the adviser implications for the small bus

post the washington consensus economic governance and industrial strategies for the twenty first century recent events in the global economy have led to a growing dissatisfaction with the neo liberal economic paradigm that has dominated economic policy over the last 30 years and the increasing concentration of and abuse of economic power within the corporate sector that has ensued however amidst calls for a new approach to economic management there is a danger that a new policy framework may overlook underlying economic governance structures that exist and may evolve within the economy such oversight has implications for development this paper seeks to demonstrate that the long run efficacy of industrial strategy depends upon designing appropriate economic governance structures that serve the wider public interest it does so by exploring past experiences of industrial strategy drawing lessons from the usa the uk japan the third italy and the emerging and transition economies we also offer some suggestions for ways forward

the creation and growth of small business service firms in post industrial britain since 1980 the united kingdom has experienced a dramatic growth in firms and employment in information intensive business services such as management consultancy and market research this article reports the results of the first substantial nation wide investigation into the nature and causes of small professional business service firm growth in britain undertaken in 1991 it reveals marked differences in the characteristics markets and competitive requirements of such firms compared with small manufacturing firms the demand for their services comes predominantly from large companies and is more focussed on financial and other services and government but small firms are also making increasing use of business services specialised expertise reputation and educational and professional qualifications are essential prerequisites for the establishment of new business service firms their success is also being enhanced by increasing use of informal networking collaborative partnerships and subcontracting

technological change and the timing of mitigation measures we use a coupled carbon cycle and energy systems engineering model to analyze the future time path of carbon emissions under an illustrative co2 concentration stabilization limit of 550 ppm our findings confirm the emission pattern as found by wre global emissions rise initially pass through stabilization in order to decline in the second half of the 21st century we show that for a given co2 concentration target emission trajectories within an intertemporal optimization framework depend mainly on two factors the discount rate and the representation of technological change as either static or dynamic we obtain a similar near term emission time path as wre when using a model with static technology and a discount rate of 7 we obtain a trajectory with lower emissions in the near term when using a lower discount rate and or treating technology dynamics endogenously in the model we briefly outline a model that endogenizes technological change through learning curves we then compare differences in emission trajectories between alternative model formulations of technological change they are sufficiently small as to be of secondary importance when compared to treating co2 concentration stabilization as an inter temporal optimization problem or not whereas our results confirm the computational results of wre we arrive nonetheless at different policy conclusions if long term emission reduction is the goal we cannot follow business as usual even in the short term action needs to start now action does not necessarily mean aggressive short term emission reductions but rather enhanced r d and technology demonstration efforts that stimulate technological learning these are the necessary preconditions that long term reduction targets can be met with improved technology and at costs lower than today we close by pointing out two further critical issues uncertainty and the possible mismatch between the world of economic models and that of climate policy

are business startups debt rationed using a large random sample of u k start ups and a rich data set the paper demonstrates that human capital is the true determinant of survival and that the correlation between financial capital and survival is spurious provision of finance is demand driven with banks supplying funds elastically and business requests governing take up firms self select for funds on the basis of the human capital endowments of the proprietors with better businesses more likely to borrow a reason why others have seemingly identified start up debt gaps may be the failure to test a sufficiently rich empirical model copyright 1996 by royal economic society

modelling small business growth and profitability this paper develops a simple structural model relating small business performance to firms market position and the characteristics of their owner managers attention focuses on two questions what determines firms choice of business strategy and how does strategy choice change subsequent business performance taking into account both relationships the paper examines the links between the performance of a large group of irish small businesses over the 1993 94 period and their market and owner managers characteristics in 1991 the analysis suggests three main empirical results first firms turnover growth and return on assets are only weakly related in the short term above average growth rates are therefore no guarantor of high profitability moreover a number of characteristics of firms market position and their owner managers are found to have the opposite effects on profitability and growth rates secondly our data provides no evidence of the persistence of turnover growth rates above or below the average above average profit rates were also found to persist only in the very short term thirdly small firm performance is shown to depend strongly on strategy choice with turnover growth being particularly strategy dependent this highlights the importance for small firms of making the correct strategy choices a point emphasised by the negative profitability and growth effects of some strategy choices one strategy choice that had positive effects on both profitability and growth was the development of new export markets

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

firm size and technical change in a dynamic context this article investigates relationship between firm size and technical change the relationship between firm size and technical change has long been a pre occupation in the literature preceding the flurry of macroeconomic studies which followed the discovery of the residual factor by solow dennison and others although this concern goes back at least to the writings of marx it was schumpeter who first emphasized the relationship between firm size and technical change for some years the assertion of schumpeter s was widely accepted but then a number of detailed empirical studies were undertaken resting on 1950s data these began to suggest that beyond a certain size inventive activity rose less than proportionately with bigness by contrast rothwell and zegveld assembled a variety of country studies some of which suggest that small and medium sized firms are relatively invention and innovation intensive in some sectors and in some countries the purpose of this paper is to argue by illustration with a single sector computer aided design cad that the above mentioned studies reach their varying conclusions in a largely static framework thus whilst there is always a tendency towards concentration in capitalism the relationship between firm size and technical change is a dynamic one ensuring that static generalisations at any single point of time are not very helpful the article is divided into sections by section iii describes the market structure in the cad sector and analyse how this has changed over the past decade section iv analyses the nature of the barriers to entry in this sector and illustrate how these are typical of other emerging software intensive microelectronic based sectors finally section v is a return discussion on the relationship between firm size and inventive activity

locational and organizational determinants of r d employment in high technology firms felsenstein d and shachar a 1988 locational and organizational determinants of r d employment in high technology firms reg studies 22 477 486 a causal model is presented that predicts the relationship between the organizational structure and location of the high technology firm on the one hand and its r d employment intensity on the other the organizational structure of the firm is treated in two ways the intra organizational internal structure of the firm is analysed and found to be significantly and negatively related to the level of r d employment in the firm this is contrary to the hypothesisied direction of relationship variables representing the inter organizational environment of the firm however are found to be associated with r d employment intensity in the manner expected the results further show that r d employment intensity is positively associated with metropolitan location unmediated by the effects of firm size this suggests that small high technology firms due to their liab

product innovation and the decision to invest in fixed capital assets evidence from an sme survey in six european union member states abstract this work explores the relationship between product innovation and the decision to invest in fixed capital assets among a sample of smes in six european union countries located in both peripheral and more central areas we find that the presence of product innovation reduces the probability to invest a firm s size exerts a direct inverted u shape effect on the probability to invest and an indirect effect through the linear effect of size on the probability to innovate the gap in the probability to invest between innovative and non innovative firms increases with size

a climate change policy induced shift from innovations in carbon energy production to carbon energy savings abstract we develop an endogenous growth model with capital labor and carbon energy as production factors and three technology variables that measure accumulated innovations for carbon energy production carbon energy savings and neutral growth all markets are complete and perfect except for research for which we assume that the marginal social benefits exceed the marginal private benefits by factor four the model constants are calibrated so that the model reproduces the relevant global trends over the 1970 2000 period the model contains a simple climate module and is used to assess the impact of induced technological change itc for a policy that aims at a maximum level of atmospheric co2 concentration 450 ppmv itc is shown to reduce the required carbon tax by more than a factor 2 and to reduce costs of such a policy by half when we do not constrain aggregate r d expenditures to benchmark levels costs are further reduced numerical simulations show that knowledge accumulation shifts from energy production to energy saving technology we discuss reasons for differences between our results and earlier results reported in the literature

the importance of equity finance for r d activity this article analyzes the importance of equity finance for the r d activity of small and medium sized enterprises we use information on almost 6 000 german smes from a company survey using the intensity of banking competition at the district level as an instrument to control for endogeneity we find that a higher equity ratio is conducive to a higher r d intensity owners may only start r d activities if they have the financial resources to sustain them until successful completion we find a larger influence of the equity ratio for young companies equity may be more important for young companies which have to rely on the original equity investment of their owners since they have not yet accumulated retained earnings and can rely less on bank financing

endogenous technological change in climate change modelling this article investigates the impact on optimal co2 abatement and carbon tax levels of introducing endogenous technological change in a macroeconomic model of climate change we analyse technological change as a function of cumulative capacity as incorporated recently in energy systems models our calculations confirm that including endogenous innovation implies earlier emission reduction to meet atmospheric carbon concentration constraints however the effect is stronger than suggested in the literature moreover the development of non fossil energy technologies constitutes the most important opportunity for emission reductions optimal carbon tax levels reducing fossil energy use are lower than usually advocated
