the action mechanism analysis of environmental pressures on the development of environmentally friendly technologies using a neo schumperian model in order to analyze the action mechanism of environmental pressures on the development of environmentally friendly technologies efts this paper constructs a neo schumpeterian simulation model containing firms production pricing pollution abatement investment environmental r d entry exit decision making and consumer choice behavior the objective of this paper is to investigate the influence of consumer demand preferences and environmental policies on firms environmental investment decision making as well as the development of eft results showed that consumers prefer product price a market based instrument mbi combined with an information oriented instrument ioi can promote the development of eft while mbi applied alone will reduce environmental investment under scenarios that consumers prefer product quality a command and control environmental policy cac can promote the development of eft to a greater extent but it inhibits environmental investment and damages the average profit rate of profit of the industry if consumers prefer environmental performance of firms cac or ioi is advantageous to the change of eft however in such a case environmental investment and consumer utility are reduced

the empirical analysis of the determinants for environmental technological change a research agenda abstract technological change is usually considered a necessary albeit not sufficient condition for a transition to sustainability however the empirical analysis of the determinants to environmental technological change has not received too much attention in the environmental ecological economics literature and many open questions remain in this context based on a careful review of the literature this paper argues that further analysis should address several issues at different levels i e regarding the conceptual framework the thematic scope of the studies some methodological issues and other aspects related to the environmental policy variable first an integrated conceptual framework which takes into account the interplay between relevant variables influencing environmental technological change i e factors internal and external to the firm and characteristics of the environmental technologies and all the stages of this process with a greater emphasis on the invention stage should be developed other aspects should then be tackled including a focus on several themes i e a greater attention to cross sectoral technologies the barriers to different types of environmental technologies the international dimension of environmental technological change and environmental technological change in small and medium size enterprises methodological issues combination of case studies and econometric modelling and several issues related to the environmental policy variable

pricing and green level decisions of a green supply chain with governmental interventions under fuzzy uncertainties abstract environmental issues make green manufacturing become inevitable and fuzzy uncertainty prevails in supply chain management in order to further promote the development of green supply chain according to channel leadership scenario we develop three game models of a green supply chain with governmental interventions under fuzzy uncertainties of both manufacturing cost and consumer demand we study how prices green levels and expected profits are influenced by channel leadership and governmental interventions green level sensitivity and fuzzy degree of parameters are considered analytical results indicate that manufacturer stackelberg scenario is the inferior structure than other scenarios and retailer stackelberg scenario is superior to other scenarios for all players under the strong governmental interventions then when governmental interventions increase the green level will increase but the tendency of retail price depends on channel leadership governmental interventions are not always beneficial to the green supply chain and the manufacturer further although the government s subsidy is offered to the manufacturer the retailer benefits from it ultimately and further becomes the main puller of the development of green products in addition a relatively high green level floor for subsidy results in the manufacturer s first mover disadvantage

design for the environment a quality based model for green product development green product development which addresses environmental issues through product design and innovation as opposed to the traditional end of pipe control approach is receiving significant attention from customers industries and governments around the world in this paper we develop a quality based model for analyzing the strategic and policy issues concerning the development of products with conflicting traditional and environmental attributes on the demand side of the problem we use the framework of conjoint analysis to structure the preferences of the ordinary and green customers on the supply side we apply the theories in optimal product design and market segmentation to analyze the producer s strategic decisions regarding the number of products introduced and their prices and qualities on the policy side we evaluate the effects of environmental standards on the economic and environmental consequences of green product development by jointly considering the interactions among the customers preferences the producer s product strategies and the environmental standards imposed by governments we present some interesting findings that can be used to manage and regulate the development of green products two major findings show that green product development and stricter environmental standards might not necessarily benefit the environment

job creation process in a transition economy in many european countries sme policy is close to being a synonym for job creation most empirical research on the job generation potential of small firms over the last decade has been done in the stable and favorable economic conditions of market economies the paper investigates the role of small firms in more difficult circumstances on an empirical data set for slovenia the paper tries to show that small firms have been the most important employer during the transition period a finding that very likely can be extrapolated for other european transition economies over the last decade slovenia has transformed from a labor managed economic system to a market oriented economy if we compare the firm size structure in a socialist like economy to the firm size structure in a mature market economy close to equilibrium we notice a typical absence of small and medium sized firms with the exception of craft shops that was how slovenia appeared in the early nineties charac terized by the removal of administrative barriers transition encouraged a spontaneous entrepreneurial wave through an expanding small business sector the ensuing changes in employment distribution changed the firm size structure

job creation and job destruction in great britain in the 1980s using data from the workplace industrial relations surveys of 1980 1984 and 1990 the authors investigate processes of job creation and job destruction in britain they find that rates of employment growth job creation and job destruction were higher at the end of the 1980s than at the beginning bothjob creation and job destruction were extremely concentrated about 50 of each was accounted for by just 4 of continuing establishments employment growth was apparently more variable in manufacturing plants than in private service sector workplaces some variables negatively related to employment growth were unionization establishment size establishment age and location in the private manufacturing sector versus private service sector

toward a theoretical model of voluntary overcompliance abstract we explain why some firms voluntarily overcomply with environmental regulation in our model all consumers value environmental quality but differ in their willingness to pay which depends on their income levels publicly available information on environmental performance of firms enables consumers to identify clean firms firms participate in a two stage duopoly game where they first choose their levels of cleaning technology and next engage in price competition the market gets segmented by income levels a minimum standard binding on the dirty firm has the effect of improving the performance of the cleaner firm a subsidy obtains the same competitive outcome

customer regulatory and competitive pressure as drivers of environmental innovation we develop an economic analysis in order to examine the effects of consumer regulatory and competitive pressure on firm investments in environmentally friendly production specifically we ask why do firms vary in their levels of environmental innovation under what conditions are such pressures effective in bringing about environmental innovation we first consider a monopolist who faces the twin pressures of reduced customer demand and regulatory penalties as a result of its emissions in response to these pressures the firm has the opportunity to make a costly investment in reduction of emissions secondly we consider a competitive scenario in which two firms compete for environmentally sensitive customers solving our model we find that pressure has the intended effect as long as the firm s initial level of emissions is below a certain threshold if the emissions are above this threshold we find that pressure might have an adverse effect on the firm s environmental investment and that subsidies that support environmental innovation can be a better alternative we also show that competition over environmentally sensitive customers can improve the effectiveness of environmental pressures

environmental innovation and environmental performance abstract by estimating a simultaneous panel data model of environmental innovation and toxic air pollution this paper identifies bi directional causal links between the two we study a panel of 127 manufacturing industries over the period 1989 2004 pollutant emissions are an implicit measure of policy stringency and environmental patent counts are used to measure environmental innovation after accounting for the joint endogeneity we find that environmental innovation is an important driver of reductions in us toxic emissions conversely we find that tightened pollution targets induce environmental innovation however our estimates indicate that the environmental policy multiplier the proportionate contribution of induced innovation to long run emission reduction is small

jobs and the business life cycle in the uk there have been a number of statistical studies in recent years of the firm life cycle its effects on employment and the role of small firms in the job generation process they have all followed the changes which take place in a population of firms through time birch based his usa national analysis on the dun and bradstreet computer files for 5 6 million establishments covering 80 of all private sector employment and some of his findings were of a controversial nature most british studies to date have been limited to single regions looking at aspects of job generation in detail there is now a series of local studies for the regions of glasgow the midlands cleveland manchester and merseyside the dti ganguly 1982a has carried out an important national study based on vat data and a sectoral study macey 1982 of manufacturing the study described here used the data of dun and bradstreet uk the commercial credit rating market research and information company to estimate job generation pe

why has the investment performance of technology specialist european venture capital funds been so poor abstract this paper seeks to identify and model the key parameters which impact on the commercial performance of a specialist technology focused early stage venture capital fund using both input costs and output expected values data provided by a number of specialist independent venture capital firms a spreadsheet model of a 10 year term fund is developed these figures are used to generate internal rate of return irr and net present value npv performance calculations for the investment commitments of both the institutional limited partners and venture capitalist general partner the generically defined model allows the user to address both conceptual and pragmatic questions regarding the relationship between fund structure and performance the model is further developed to determine the effect on fund performance of two venture capital related indirect state support schemes guarantee and leverage options iterative interrogations of the model demonstrate the sensitivity of economic returns to the scale of the investment activity state supported schemes mitigate but do not remove the negative performance consequences of small fund size a fund with under 15 million us 25 million or ecu21 million under management is of increasing economic vulnerability

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

the manufacturing sector s environmental motives a game theoretic analysis what motivates manufacturing companies to make costly investments in producing in an environmentally clean manner the traditional argument is that such behaviour is value reducing and that therefore firms must be forced by regulation to invest in green production processes a counter argument is that firms have an incentive to make environmental investments in an attempt to attract green consumers and investors hence gaining competitive advantage over their rivals in this paper we employ a game theoretic approach that demonstrates that competing firms incentives to make voluntary investments in environmental clean up are affected by the size of the investment costs and the extent of consumer and investor green awareness we argue that an increase in green behaviour can be induced by a combination of governmental subsidies for firms that invest in environmentally clean production processes together with an education program that promotes green awareness amongst consumers investors and the managers themselves

the pass through effects of oil price shocks on china s inflation a time varying analysis abstract using a time varying parameter structural vector autoregression with stochastic volatility tvp svar sv model we decompose the structural shocks of oil price fluctuations into four types oil supply shocks global demand shocks domestic demand shocks and oil specific demand shocks we then analyze the time varying effects of these oil price shocks on china s inflation at the import production and consumption stages using monthly data from january 1999 to december 2016 the results show that the pass through effects of the four types of oil price shocks on china s inflation at each stage are time varying and that there are significant differences at different time horizons and points in time the analysis of the variance decomposition shows that the effects of oil price shocks on china s inflation at each stage are incomplete and decrease along the price chain the increase in oil prices driven by oil specific demand shocks is the most important cause of china s inflation at the import and production stages during the full sample period while china s inflation at the consumption stage is mainly affected by domestic demand shocks in addition the inflationary effects of oil price shocks have been dramatically weaker since the international financial crisis compared with before the crisis

evolutionary framework design in formulation of decision support models for production emissions and net profit of firm implications on environmental concerns of supply chains abstract there have been increased investments in cleaner technologies and adoption of a voluntarily limit on transportation emissions by the global firms to handle the environmental concerns of supply chains and to increase demand for finished goods consequences are the reduction in net profit for the firm to address this trade off between the net profit and environmental concerns the formulation and optimization of a compact model are needed development of these models requires a thorough understanding of the nature of the impact of three inputs investment coefficient penalty per unit emission and customer s emission elasticity on production emissions and net profit past studies revealed that a compact model comprising the interactive effect of these inputs on the production emissions and net profit is not yet formulated therefore this study illustrates the development of an evolutionary framework of an advanced multi gene genetic programming in the formulation of functional expressions for the net profit and production emissions based on the three inputs investment coefficient penalty per unit emission and customer s emission elasticity of the monopolist firm the sensitivity and parametric based 2 d analysis determine the relationships and found that the penalty per unit emission is dominant input for reducing emissions and maintaining net profit simultaneously the contribution of this work lies in designing of an evolutionary framework in the development of empirical explicit expressions which can easily be optimized analytically to keep production emissions and net profit balanced

the impact of environmental management on firm performance environmental management has the potential to play a pivotal role in the financial performance of the firm many individuals suggest that profitability is hurt by the higher production costs of environmental management initiatives while others cite anecdotal evidence of increased profitability a theoretical model is proposed that links strong environmental management to improved perceived future financial performance as measured by stock market performance the linkage to firm performance is tested empirically using financial event methodology and archival data of firm level environmental and financial performance significant positive returns were measured for strong environmental management as indicated by environmental performance awards and significant negative returns were measured for weak environmental management as indicated by environmental crises the implicit financial market valuation of these events also was estimated cross sectional analysis of the environmental award events revealed differences for first time awards and between industries first time award announcements were associated with greater increases in market valuation although smaller increases were observed for firms in environmentally dirty industries possibly indicative of market skepticism this linkage between environmental management and financial performance can be used by both researchers and practitioners as one measure of the benefits experienced by industry leaders and as one criterion against which to measure investment alternatives

employment change in the small business sector evidence from five manufacturing industries this paper examines the scale and nature of employment flows into and out of the small business sector sbs in five united kingdom manufacturing industries over the period 1979 85 it first provides a taxonomic framework for analysing these flows it then draws on specially prepared analyses from the annual census of production acop for the uk to show that the sbs in each industry has experienced very substantial turbulence although the sbs across all five industries lost only four per cent of 1979 employment over the period movement in and out each represented about half of 1979 employment most gains and losses were in the very small size bands the paper also briefly explores the relationship between births and deaths and industrial characteristics across the five industries the study raises questions about the causes and costs of high turbulence in the sbs it also demonstrates the potential value of the acop data base for longitudinal studies of business in the uk 1

environmentally responsible inventory models non classical models for a non classical era abstract mathematical models of inventory typically include the three inventory associated costs of surplus shortage and ordering these classic inventory models are then analysed so as to choose inventory parameters that usually minimise the total cost of operating the inventory system being investigated unfortunately classic inventory models do not provide a meaningful basis for analysing many real and increasingly important practical inventory problems and situations it is therefore not surprising that over recent years several authors have discussed these issues in broad terms and suggested that a new paradigm needs to be developed this paper develops some specific aspects of this discussion in particular the paper identifies a range of inventory problems that are not covered appropriately by traditional inventory analysis one of these is to design responsible inventory systems i e systems that reflect the needs of the environment the paper then examines the importance of inventory planning to the environment in greater detail for example packaging is important not only because of its costs and the protection that it provides to the inventory items but also because of its eventual effects on the environment in terms of the use of resources and potential landfill for similar reasons waste which can result from poor inventory management is highly important the location of stores is important because location affects transport costs thus the influence of the secondary aspects of most inventory models packaging waste and location are important but even more important are the inter relations with the total system in particular the location of the manufacturing plants and the effect that inventory planning has on the logistics chain potentially have considerable environmental implications inventory is part of a wider system however until the cost charged for an activity reflects the true environmental cost of that activity it is likely that decisions will be made on the basis of erroneous data in that situation we are faced with either determining the environmental cost of specific actions or to use environmental costs that are somewhat contrived in which case it may be more sensible to use very different performance measures and models the paper discusses these ideas and ways in which inventory policies may reassure us with our environmental concerns

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

determinants of environmental innovation in us manufacturing industries abstract this paper provides new evidence on the determinants of environmental innovation we employ panel data models to study how environmental innovation by us manufacturing industries responded to changes in pollution abatement expenditures and regulatory enforcement during the period 1983 through 1992 we find that 1 environmental innovation as measured by the number of successful environmental patent applications granted to the industry responded to increases in pollution abatement expenditures however 2 increased monitoring and enforcement activities related to existing regulations did not provide any additional incentive to innovate we also find some empirical evidence that environmental innovation is more likely to occur in industries that are internationally competitive

tax subsidy policies in the presence of environmentally aware consumers abstract we study policy measures to improve environmental quality in the presence of environmentally aware consumers we consider two sets of policy instruments uniform policies for the firms and policies that discriminate between the firms based on their environmental quality for the latter set either the better performer is rewarded with a subsidy or the worse performer is punished with a tax we find that while a uniform subsidy policy improves average environmental quality a uniform tax policy worsens it further while a discriminatory subsidy policy reduces total pollution and enhances aggregate welfare a discriminatory tax policy may increase total pollution and may reduce aggregate welfare

the growth of uk companies and their contribution to job generation 1985 1987 theories of firm growth are reviewed and various models examined the firm growth and job generation process in the uk over the period 1985 87 is examined empirically by using the very large data files of the dun and bradstreet credit rating organisation in the analysis four computer processes were carried out the sorting and matching of files the cleaning of the data the validation of the cleaned data and the scaling up the results the final adjusted data were grossed up to provide an overview of the growth and job generation potential of uk firms this is compared with past results for the periods 1971 81 and 1982 84 small firms performed well providing 48 of all new jobs although consisting of only 21 of all employment in 1985 the 1000 employee range provided only 13 of all new jobs over the period although consisting of 37 of all employment in 1985 an overall trend of positive performance in smaller firms and negative in larger firms was apparent the 20 49 employee cohort performed unusually poorly in firm and job creation against the expected pattern the effect of takeovers mergers and rationalisations on employment was examined as expected there was negligible restructuring of small firms but over 5 of employees in the largest 1000 cohort were involved in some form of reorganisation
