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

environmental regulation industrial innovation and green development of chinese manufacturing based on an extended cdm model abstract as for the academics and policymakers more attention has been given to the issue on how to drive green development of the manufacturing through regulations and innovations we construct the extended crepon duguet mairesse cdm model and employ the panel data of chinese manufacturing industries during 2003 2014 to examine the effects of environmental regulation on industrial innovation and green development the findings reveal that 1 in the long term environmental regulation has crowded out r d investment 2 environmental regulation has inhibited patent outputs so that the weak version of porter hypothesis is not underpinned 3 in the short term environmental regulation has promoted the improvements of labor productivity energy efficiency and environmental efficiency in the manufacturing industry excluding green total factor productivity gtfp whereas in the long term environmental regulation only has increased energy efficiency while it has obstructed labor productivity which provides no support for the strong version of porter hypothesis 4 different innovation outputs have distinct influences on labor productivity energy efficiency environmental efficiency and gtfp finally this paper provides pertinent policy implications

optimal retailer investments in green operations and preservation technology for deteriorating items abstract this paper examines the impact of dynamic retailer investments in green operations while considering the reference price effect a replenishment problem based on joint pricing dynamic investment in green operations preservation technology and optimal replenishment times for deteriorating items is considered as a way to maximize retailer profit in this problem the demand rate depends on the sales and reference prices as well as green concern level optimal control theory is employed to obtain a dynamic investment rate and a simulated annealing algorithm is used to find the solution of the nonlinear constraint optimization problem which determines the price preservation technology investment and replenishment cycle time in addition computational simulations and sensitivity analyses are carried out to offer managerial insights the findings suggest that continuous investment in green operations and preservation technology can significantly improve the retailer s financial performance the consumer reference price is an important influence on the retailer s decision to invest in green operations furthermore results show that the higher price sensitivity of the market always discourages the retailer from investing in green operations the retailer needs to invest more in green operations for products with relatively high unit value

uncertainty and the timing of an urban congestion relief investment the no land case we analyze the impact of population uncertainty on the socially optimum timing of a congestion relief project in a linear monocentric city with fixed boundaries where congestion pricing cannot be implemented this project requires time to bear fruit but no urban land under certainty we show that utility maximization is roughly equivalent to a standard benefit cost analysis bca under uncertainty we derive an explicit optimal threshold for relieving congestion when the urban population follows a geometric brownian motion if the time to implement the project is short we show analytically that deciding on the timing of congestion relief based on a bca could lead to acting prematurely the reverse holds if project implementation is long and uncertainty is large enough

changes in returns to education in latin america the role of demand and supply of skills using micro data for the urban areas of argentina brazil chile colombia and mexico the authors document trends in men s returns to education during the 1980s and the 1990s and estimate the role of supply and demand factors in explaining the changes in skill premia they propose a model of demand for skills with three production inputs corresponding to workers with primary secondary and university level education further the authors demonstrate that an unprecedented rise in the supply of workers having completed secondary level education depressed their wages relative to workers with primary level education throughout latin america this supply shift was compounded by a generalized shift in the demand for workers with tertiary education

the effect of clean water regulation on profitability testing the porter hypothesis previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability this study provides empirical evidence on this debated effect by testing the strong version of the porter hypothesis we employ panel data analysis to examine the effect of water regulation as measured by permitted wastewater discharge limits on the profitability of publicly held firms operating within the chemical manufacturing industries we find that tighter water regulation meaningfully lowers profitability by reinterpreting profitability in terms of sales and costs the results demonstrate that tighter water regulation increases costs conditioned on a given level of sales

jobs versus amenities in the analysis of metropolitan migration abstract this paper demonstrates that jobs and wages are considerably more important than location specific amenities in explaining net metropolitan migration of employed persons these results which are derived mainly from a unique set of annual migration data differ considerably from the earlier findings of p e graves j urban econom 6 135 147 1979 that show amenities to be powerful contributors to the analysis of net metropolitan migration several hypotheses are offered and tested to explain the appreciable difference between graves s results and those of the present study but the importance of economic factors as opposed to amenities persists the findings of this study are generally consistent with the earlier findings of muth southern econom j 37 295 306 1971

migration theories and evidence an assessment abstract this paper presents a critical survey of theories of migration their welfare and policy implications and their empirical relevance we also develop some extensions to the theory beginning with the harris and todaro ht model in particular the ht model is extended to examine risk averse behaviour within families where the migration of members of families serves to diversify risk the welfare implications of the individual migration decision and government intervention in the form of employment subsidies are examined recent evidence on international migration is presented it is shown that migration does not flow automatically in response to wage differentials characteristics of migrants and the process of self selection are found to be important determinants of the rate of migration

technology and the us labor market evidence from the sectoral and regional decomposition of the change in the us workforce skill mix abstract researchers have found indirect evidence supporting the role of technology in changing the workforce skill mix in the us by decomposing the change in the skill mix into within between industry components this paper provides additional support for the role of technology by extending the decomposition analysis into both the sectoral and the regional dimensions

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

understanding the puzzling risk return relationship for housing standard theory predicts a positive relationship between risk and return yet recent data show that housing returns vary positively with risk in some markets but negatively in others this paper rationalizes these cross market differences in the risk return relationship for housing and in so doing explains the puzzling negative relationship the paper shows that when the current house provides a hedge against the risk associated with the future housing consumption households are willing to accept a lower return to compensate for risk thus weakening the positive risk return relationship further in markets with less elastic housing supply and a growing population hedging incentives can be sufficiently strong to make the relationship negative the empirical analysis confirms these predictions suggesting that hedging incentives housing supply and urban growth are indeed central to understanding the risk return relationship for housing the author 2013 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press

beyond the question does it pay to be green how much green and when abstract this research investigates the relationship between green management and performance in italian firms the analysis compares innovation and productivity of firms with similar features but different environmental activities firms are matched on a rich set of covariates extending the coarsened exact matching to survey data matched data are analysed with parametric and non parametric tests and endogenous treatment regression the analysis shows that the relationship between green management and performance is u shaped green firms are performing no better than firms with no environmental activity especially in energy intensive sectors among green firms more advanced environmental management is associated with higher performance overall the results suggest that green management has strong sectoral patterns and no linear relationship with performance findings suggest that green managers should pursue a comprehensive environmental management system sectoral specific policies to promote environmentally friendly activities are needed when green activities are not paying off

testing the present value relation for housing prices should i leave my house in san francisco abstract we examine the efficiency of residential housing markets by examining price rent and cost of capital indices generated from a transactions level data base for alameda and san francisco counties in northern california we can reject both constant and nonconstant discount rate versions of the housing price present value relation in the short run long run results are consistent with the housing price present value relation when we adjust the discount factor for changes in both tax rates and borrowing costs that characterize our 1970 1988 sample period our preferred explanation for the short run rejection of but long run consistency with the present value model is the high transaction costs that characterize the housing market however we cannot rule out the possibility that deviations of actual and present value price are due to asset market bubbles or nonrational expectations

regional labor markets and the determinants of wage inequality from 1972 to 1990 the united states experienced the largest increase in wage inequality of any developed country the spread in log wages between the 90th and 10th percentiles of the male wage distribution increased by about 60 points and inequality increased within virtually every demographic or skill category of the labor force see chinhui juhn et al 1993 various explanations have been offered including changes in the relative demand for skill intensive goods international trade immigration of less skilled workers and increased labor force participation of women yet attempts to quantify the relative importance of these factors have not met with much success this leaves skill biased technical change as the residual claimant that rationalizes the data this paper uses regional differences in the evolution of wage inequality to provide new evidence on the determinants of relative wages using a model of factor demand in geographic markets i isolate contributions of i changing skill ratios in the labor force ii increased participation of women iii technical change and iv changes in the industrial composition of labor demand the data indicate that changing skill ratios and women s labor supply have affected the wages of low skilled men in the west the data indicate that increased immigration of less skilled hispanic and asian workers has adversely affected the wages of natives causing a greater increase in inequality there than in any other region of the country i modeling wage inequality in regional markets

strategic control of growth in a system of cities abstract this paper provides an analysis of the supply restriction model of growth controls growth controls in such a model harm consumers while enriching landowners and they will only be adopted if landowners have political power in the model this power is manifested in the city government s use of a social welfare that takes both landlord and consumer welfare into account since cities cannot be small if the supply restriction inherent in growth controls is to have an impact strategic interactions must be considered in the analysis of city choices a general model is presented and an extended example based on leontief preferences is then considered comparative static analysis of nash equilibria in the leontief case shows that perturbations of preferences or other characteristics of a single city can have important spillover effects that alter the choices of all cities in the region

the dynamic capabilities of firms an introduction an expanded paradigm is needed to explain how competitive advantage is gained and held firms resorting to resource bas ed strategy attempt to accumulate valuable technology assets and employ an aggressive intellectual property stance however winners in the global marketplace have been firms demonstrating timely responsiveness and rapid and flexible product innovation along with the management capability to effectively coordinate and redeploy internal and external competences this source of competitive advantage dynamic capabilities emphasizes two aspects first it refers to the shifting character of the environment second it emphasizes the key role of strategic management in appropriately adapting integrating and re configuring internal and external organizational skills resources and functional competences toward changing environment 3 only recently have researchers begun to focus on the specifics of developing firm specific capabilities and the manner in which competences are renewed to respond to shifts in the business environment the dynamic capabilities approach provides a coherent framework to integrate existing conceptual and empirical knowledge and facilitate prescription this paper argues that the competitive advanis tage of firms stems from dynamic capabilities rooted in high performance routines z operating inside the firm embedded in the firm s processes and conditioned by its history it offers dynamic capabilities as an emerging paradigm of the modern business j firm that draws on multiple disciplines and advances with the help of industry studies in the usa and elsewhere

agricultural profits and farm household wealth recent decades especially since 1973 have been an era of decreasing production profits that threaten the survival of many midand small sized american farms blank 2003 normally the survival of a firm depends on its profitability both in absolute and relative terms to remain viable a firm must offer returns that are both sufficient to cover the owner s financial obligations and competitive with returns from alternative investments if a firm is profitable the wealth of its owners can increase over time an unprofitable firm on the other hand reduces owners wealth yet american agriculture is full of firms that routinely earn low or negative returns on equity from production operations blank 2002 thus complicating the evaluation of the industry s economic health and prospects this suggests that macro level forecasts of american agriculture s future structure and performance require a micro level understanding of the relationship between farm profits and owner wealth this paper addresses that relationship

sustainable production and consumption systems cooperation for change assessing and simulating the willingness of the firm to adopt develop cleaner technologies the case of the in bond industry in northern mexico abstract over the last decade literature on the greening of industry and environmental policy has provided numerous important insights into the determinants of the firm s innovative behaviour in cleaner technologies however this literature still lacks empirically tested theoretical models this paper contributes to fill this gap proposing a definitional system that enables the testing of hypotheses of dependence between willingness to innovate in cleaner technologies and its determinants and to explore the conditions under which the firms innovative behaviour could be fostered regression and simulation outcomes indicate against the general wisdom that stringent environmental regulation without consideration to the dynamics of technical change and environmental and economic risk perceptions in the part of firms would play against the promotion of innovation in cleaner production

a resource based perspective on corporate environmental performance and profitability drawing on the resource based view of the firm we posited that environmental performance and economic performance are positively linked and that industry growth moderates the relationship with the returns to environmental performance higher in high growth industries we tested these hypotheses with an analysis of 243 finns over two years using independently developed environmental ratings results indicate that it pays to be green and that this relationship strengthens with industry growth we conclude by highlighting the study s academic and managerial implications making special reference to the social issues in management literature

lead markets and regulation a framework for analyzing the international diffusion of environmental innovations abstract environmental regulations are often intended to stimulate the generation and adoption of eco efficient innovations an important argument in the public debate is also the creation of new markets for environmentally benign products processes and services in other countries and the generation as a result of export opportunities for the pioneering country lead markets research on lead markets has not however focused on environmental innovations to date we therefore extend the lead market model to environmental innovations and take particular account of the peculiarities of such innovations in particular the public good character of environmental benefits and the role of regulations this approach is applied to two case studies wind energy and fuel efficient passenger cars in both cases the innovation was initially adopted in one country other countries subsequently adopted the same innovation design favored by the lead market which in turn developed into a large exporter in the wind generation and car industries respectively we discuss the regulations employed and the reasons for the international success of the innovations induced by them our findings demonstrate that when supported by global demand or regulatory trends strict regulation results in the creation of lead markets finally we provide recommendations on how our model could be used for further research and in the development of a coordinated environmental and innovation policy

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

immigrants minorities and labor market competition this paper investigates the extent of labor market competition among immigrants minorities and the native population an analysis of 1980 u s census data reveals that immigrants tend to be substitutes for some labor market groups and complements for others the effects of shifts in immigrant supply on the earnings of native born men are however very small on the other hand increases in the supply of immigrants do have a sizable impact on the earnings of immigrants themselves an increase of 10 percent in the supply of immigrants for example reduces the immigrant wage by about 10 percent

it pays to be green a premature conclusion it has been claimed that good environmental performance can improve firms economic performance however because of e g data limitations the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings we discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of norwegian plants a pooled regression where observable firm characteristics like e g size or industry are controlled for confirms a positive effect of environmental performance on economic performance however the estimated positive effect could be due to omitted unobserved variables like management or technology when the regression model controls for unobserved plant heterogeneity the effect is generally no longer statistically significant hence although greener plants tend to perform economically better the analysis provides little support for the claim that it is because they are greener these empirical findings further indicate that a conclusion that it pays to be green is premature

the dynamics of technological substitution the case of eco innovation diffusion of surface cleaning products some eco innovations have already reached a mature state but they diffuse slowly there is little known about the importance of various factors on the diffusion process of eco innovations the aim of this research is to propose a conceptual model for eco innovation diffusion where particular case study of eco innovation micro fibre cloth mfc for surface cleaning purposes is given the work will study the relative importance of various motivations on diffusion processes as well as the influence of information campaigns this novel methodology has been developed under the system dynamics framework and is coupled with the logistic regression model structural validation tests were done for the proposed model the methodology is proposed then the integrated empirical study and system dynamics model are completed the results of the logistic regression models show that the overall attitudes and social influence has the most dominant impact on intention to use the studied eco innovation products the most sensitive parameters in the system dynamics model were found to be the adoption faction of information received by word of mouth households adopting micro fibre cloth at the beginning of the simulation and the contact rate per household the proposed methodology and developed mathematical model can also be used as the basis for other studies of other diffusion processes since system dynamics modelling is a white box modelling approach and the structure of the model can be enhanced with the latest results from other studies

green r d for eco innovation and its impact on carbon emissions and firm performance abstract over the past four decades the results of the debates about the relationship between corporate environmental performance and corporate financial performance have remained inconclusive due to the lack of theoretical underpinning and availability of data this paper examines the impact of green research and development investment for eco innovation on environmental and financial performance the research is based on the resource based view and the natural resource based view which explicitly recognize the importance of resources and capabilities using a sample of japanese manufacturing firms during the period of 2001 2010 the study focuses on green research and development investment as a key proxy of eco innovation and carbon emissions in environmental performance our results show the presence of a negative relationship between green research and development and carbon emissions while green research and development is positively related to financial performance at the firm level our findings explicitly support that in order for firms to adopt a proactive environmental strategy to manage their environmental and financial performance to the best advantage they urgently need to organise unique resources and capabilities the findings of this study provide valuable insights and basis of scientific debate on how firms to engage unique organizational resources and capabilities for superior corporate environmental and financial performance

do corporate global environmental standards create or destroy market value arguments can be made on both sides of the question of whether a stringent global corporate environmental standard represents a competitive asset or liability for multinational enterprises mnes investing in emerging and developing markets analyzing the global environmental standards of a sample of u s based mnes in relation to their stock market performance we find that firms adopting a single stringent global environmental standard have much higher market values as measured by tobin sq than firms defaulting to less stringent or poorly enforced host country standards thus developing countries that use lax environmental regulations to attract foreign direct investment may end up attracting poorer quality and perhaps less competitive firms our results also suggest that externalities are incorporated to a significant extent in firm valuation we discuss plausible reasons for this observation

environmental innovations and profitability how does it pay to be green an empirical analysis on the german innovation survey much of the empirical literature analysing the relation between environmental innovation and competitiveness has focused on the question whether it pays to be green we differentiate between different types of environmental innovations which will be disentangled in those aiming at reducing the negative externalities and those allowing for efficiency increases and cost savings what we analyze is at first the extent to which these two typologies have impacts on firms profitability with opposite signs and secondly whether the motivations driving the adoption of those innovations make the difference in terms of economic gains we find empirical evidence that both the typology of environmental innovation and the driver of their adoption affect the sign of the relationship between competitiveness and environmental performance the empirical strategy is based on a sample of german firms and makes use of a merge of two waves of the mannheim innovation panel in 2011 and 2009 that allow overcoming some endogeneity issues which may arise in a cross section setting

the open eco innovation mode an empirical investigation of eleven european countries this paper deals with the open innovation mode in the environmental realm and investigates the effects that knowledge sourcing has on the environmental innovations eis of firms using the community innovation survey cis 2006 2008 we refer to the firm s probability of both introducing an ei and extending the number of ei typologies adopted we estimate the impact of the depth and breadth of knowledge sourcing in addition we test for the moderating role of the firm s absorptive capacity knowledge sourcing has a positive impact on both types of ei performance however a broad sourcing strategy reveals a threshold above which the propensity to introduce an ei diminishes cognitive constraints in processing knowledge inputs that are too diverse may explain this result absorptive capacity generally helps firms to turn broadly sourced external knowledge into ei however internal innovation capabilities and knowledge socialization mechanisms seem to diminish the ei impact of knowledge sourced through deep external interactions the possibility of mismatches between the management of internal and external knowledge and of problems in distributing the decision makers attention between the two may explain this result

the driving forces of process eco innovation and its impact on performance insights from slovenia this study endeavors to explore the driving forces of process eco innovation and its effect on company performance by adopting an integrative approach we focus on process eco innovation which pertains to technological and non technological solutions that result in a reduction of material and energy costs for companies in this regard the study sheds light on the drivers and outcomes of process eco innovation adoption using data collected from 223 slovenian companies the results reveal that certain determinants i e competitive pressure customer demand managerial environmental concern command and control instrument and economic incentive instrument are conducive to the deployment of process eco innovation empirical evidence reveals competitive pressure as the most influential driving force of process eco innovation followed by managerial environmental concern and customer demand effectiveness in spurring process eco innovation is also found to be a command and control instrument and an economic incentive instrument while expected benefits do not spur process eco innovation pertaining to the outcomes of process eco innovation adoption we can conclude that it pays to be eco process eco innovation is worthwhile in terms of company profitability growth and competitive benefits these findings suggest several courses of action for both policy makers and companies hence we conclude by providing implications for both

aspects of growth in a system of cities abstract this paper explores and develops the modeling of growth in a system of cities in two alternative settings first we examine a large growing economy with a fully developed system of cities with perfectly malleable private and public capital local scale economies in production and diseconomies in consumption in equilibrium offset each other at the margin so that from a national point of view we have a constant returns to scale economy we show that at the steady state the number of cities grows exponentially at the rate of growth of the population we then examine the impact of technological change considering a case where public capital is not perfectly malleable in the second setting we consider the problem of growth for a small economy and discuss problems associated with the transition to the steady state we modify the previous model to describe a system of cities that is just starting to develop investment in public infrastructure capital is subject to sharp indivisibilities and as a result new cities are built at discrete points in time

investigating policy and r d effects on environmental innovation a meta analysis in the last decades a wide research effort has been devoted at the analysis of the determinants of environmental innovation ei whereas agreement seemed to emerge around a cluster of determinants mainly technology push market pull policy push pull and firm specific factors empirical analyses have failed to provide strong confirmation on the relevance of some core variables after a qualitative discussion of this literature we empirically assess it by exploiting meta regression analysis techniques to test the effectiveness of two determinants policy and r d our findings are clear as for the first we show that only certain types of policy have proven to affect ei in particular regulatory stringency as for r d we show that the use of estimation methods is not neutral to the outcome of the primary studies

development and utilization of energy related technologies economic performance and the role of policy instruments the present study investigates the effects of energy related technologies on economic performance at firm level we distinguish clearly between adoption and use of energy related technologies process innovation in the broad sense and product innovation in energy related fields we take into consideration four energy related policy instruments and expected demand for energy related new products and services we investigate the possibility of indirect effects of policy on performance via adoption or innovation by interacting adoption and innovation variables with policy instrument dummies we test our hypotheses not only for the pooled data but also separately for the three countries austria germany switzerland that are taken into consideration in this study we find a positive direct effect of investment expenditures for energy related technologies on labour productivity that measure intensity of adoption of energy related technologies and a positive indirect effect of energy taxes via investment in energy related technologies further we find positive direct and indirect effects of regulation standards and voluntary agreements via the adoption of production related technologies and for technologies for the generation of renewal energy sources we find neither direct nor indirect effects of the sales of innovative energy related products that measure product innovation in energy related products on labour productivity no differences among the three countries could be detected with respect to investment in energy related technologies and sales of innovative energy related products the indirect effects of regulation and standards and voluntary agreements can be primarily traced back to german firms

eco innovation and regulatory push pull effect in the case of reach regulation empirical evidence based on survey data abstractnumerous theoretical and empirical studies provide evidence of a positive correlation between eco innovation and environmental regulation however few analyses explain how environmental policies drive eco innovation this article studies eco innovation friendly mechanisms in the design of european reach registration evaluation authorization of chemicals regulation the aim of reach which became effective in 2007 is to ensure a high level of protection of human health and the environment while improving competitiveness and innovation which makes it appropriate and original for analysing the relationship between environmental regulation and eco innovation the primary contribution of this article is to provide a new theoretical and empirical perspective on eco innovation by showing how design regulation is able to push and pull the environment innovation based on an original survey related to reach regulation the econometric model shows that 1 regulatory push mechanisms seem to be more

the innovation effects of environmental policy instruments a typical case of the blind men and the elephant abstract in this paper we examine the innovation effects of environmental policy instruments in four literatures theoretical models on incentives for eco innovation econometric studies based on observed data survey analysis based on stated information and technology case studies the aim of this paper is to critically examine the methods and the results we argue that the case studies literature even when its results are specific and difficult to generalise is a necessary source of empirical evidence about policy impacts and the factors responsible for these impacts pointing to issues that are neglected in the theoretical and econometric literature such as the specifics of the innovation context and policy interaction effects the paper states five synthesised findings and makes a plea for multi method analysis one other important synthesised finding is that the influence of market based instruments on innovation such as emission trading and taxes is far weaker than assumed

general wisdom concerning the factors affecting the adoption of cleaner technologies a survey 1990 2007 abstract cleaner technologies ct have recently received much attention in diverse media and policy agendas this comes out of the clear role they play in environmental protection and sustainability and the large potential to contribute to economic growth and competitiveness the realization of both potentials depends on the level diffusion and exploitation achieved today very low this article presents a selective survey of papers that today represent the general wisdom concerning the factors affecting adoption as a primary condition to diffusion and exploitation of ct the paper helps to clarify the challenges facing diffusion modelers and policy makers when dealing with policy design assessing the levels of diffusion achieved as well as the factors affecting diffusion of a particular technology the paper ends outlining further research need in the field

environmental innovations in services manufacturing services integration and policy transmissions abstract this paper investigates the relevant factors behind the almost unexplored realm of environmental innovation in services using a dataset of 8161 italian service firms specifically we test whether manufacturing services integration matters for environmental innovations in addition taking account for the heterogeneity of the service industries we analyse whether environmental policies for manufacturing transmit induced innovation effects to services our findings show that i the drivers of environmental innovations related to carbon abatement and energy efficiency differ across industries and ii cooperation training environmental management systems and public funding play key roles in these processes the integration of services and manufacturing through push and pull effects and the environmental policy transmission effect from manufacturing to services generally do not seem to have a positive impact on the diffusion of environmental innovations

the effect of income taxes on household income research on the distribution of income during the 1980s has identified a trend towards increasing inequality which may be the continuation and acceleration of trends spanning several decades this paper explores to what extent behavioral responses to the tax changes during the 1980s may also explain the rising inequality the 1986 tax reform act is used as a natural experiment to explore the roles played by both taxes and a variety of nontax factors our principal finding is that both tax rates and nontax factors appear to have had significant effects on relative income growth during the late 1980s

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

the stochastic city abstract this paper analyzes a simple model of an urban area with growth and uncertainty household income rents and prices for land follow stochastic processes even though investors are risk neutral uncertainty affects both land rents and land prices in equilibrium because the conversion of land from agricultural to urban use is irreversible growth on the other hand affects urban and agricultural land prices but not the level of rents we show that uncertainty i delays the conversion of land from agricultural to urban use ii imparts an option value to agricultural land iii causes land at the boundary to sell for more than its opportunity cost in other uses and iv reduces equilibrium city size

does environmental performance affect financial performance a meta analysis abstract what do we know about the impact of environmental regulations performance on firm performance after more than three decades of theoretical as well as empirical research the results seem to remain inconclusive some papers suggest that regulations harm firms while others claim that regulations may contribute positively and give an impetus to innovations therefore i examine the heterogeneity in financial environmental performance nexus empirically carrying out a meta regression analysis of 64 outcomes from 37 empirical studies to uncover the underlying factors which can influence the observed variation in the empirical results the results suggest both that the empirical method used matters for the nexus and that the likelihood of finding a negative link between environmental and financial performance significantly increases when using simple correlation coefficients instead of more advanced econometric analysis the results also indicate that the portfolio studies tend to report a negative link between environmental and financial performance this likely reflects the omitted factors in portfolio studies the positive link is found more frequently in common law countries than in civil law countries the results also point to the importance of appropriate time coverage to establish a positive link between environmental and financial performance

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

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

the decline of welfare benefits in the u s the role of wage inequality welfare benefits in the u s have experienced a much studied secular decline since the mid 1970s we explore a new hypothesis for this decline related to the increase in wage inequality in the labor market and the decline of real wages at the bottom of the distribution we posit that voters prefer benefits which are tied to low skilled wages we test the hypothesis using a 1969 1992 panel of state level data an additional contribution of our analysis is the use of general social survey data on voter preferences for welfare which we combine with current population survey data to determine the voter in each state who has the median preferred welfare benefit level our analysis reveals considerable evidence in support of a role for declining real wages in the decline of welfare benefits

relationships between eco innovation and financial performance evidence from publicly traded companies in poland and hungary while the analysis of the linkages between eco innovative activities and financial performance is a popular topic in the existing body of literature many questions about these relationships especially in transition economies in central and eastern europe cee remain unanswered in this paper we explore four types of eco innovation product process market and sources of supply and their impact on accounting based measurers of financial performance using the data on polish and hungarian publicly traded companies from the years 2006 2013 our results indicated that eco innovators were generally characterized by higher returns on assets and equity and lower earnings retention additionally companies that introduce eco innovation were also significantly larger more likely to face lower financial risk exposure and more likely to possess greater free cash flow than conventional firms the findings suggest that strong asset and financial capabilities are relevant pre conditions for the development of eco innovativeness and that there is a need for environmental policy to create clear incentives for smes to increase activities in that area overall this study extends the understanding of financial performance implications of innovation by focussing on the area of environmental innovation

differences in metropolitan and nonmetropolitan u s family income inequality a cross county comparison abstract u s family income inequality is examined using 1990 cenus of population data for the 3109 counties and independent cities in the 48 contiguous states use of counties as the unit of analysis extends previous research on u s income inequality that relied on national state or metropolitan level data in addition including both metropolitan and nonmetropolitan counties allows us to determine whether income inequality differs between them after controlling for a variety of labor market demographic and regional characteristics as another innovation we also consider whether counties that experienced recent structural changes in industry composition have higher income inequality

aggregation bias in elasticities of substitution and the minimum wage paradox while the employment effects of minimum wages are usually reported to be small suggesting low substitutability between skill types direct estimates suggest a much larger degree of substitutability this article argues that this paradox is largely due to a bias induced by the aggregation of skill types into broad categories an assignment model is applied where skilled workers have a comparative advantage in complex jobs the implied pattern of substitutability reveals the sources of the bias estimation results for the united states show elasticities of complementarity to be underestimated by up to a factor 2 5 the methods laid out likewise can be applied to other markets where different quality types are close substitutes such as the housing market

environmental regulation and the export dynamics of energy technologies abstract the pollution haven hypothesis affirms that an open market regime will encourage the flow of low technology polluting industries toward developing countries because of potential comparative advantages related to low environmental standards in contrast the hypothesis suggested by porter and van der linde claims that innovating firms operate in a dynamic competitive situation which allows global diffusion of environmental friendly technologies environmental regulation may represent a relevant mechanism through which technological change is induced in this way countries that are subject to more stringent environmental regulations may become net exporters of environmental technologies this paper provides new evidence on the evolution of export flows of environmental technologies across different countries for the energy sector advanced economies particularly the european union have increasingly focused on the role of energy policies as tools for sustaining the development path the kyoto protocol commitments together with growing import dependence on energy products have brought attention to the analysis of innovation processes in this specific sector the analysis uses a gravity model in order to test the determinants and the transmission channels through which environmental technologies for renewable energies and energy efficiency are exported to advanced and developing countries our results are consistent with the porter and van der linde hypothesis where environmental regulation represents a significant source of comparative advantages what strongly emerges is that the stringency of environmental regulation supplemented by the strength of the national innovation system is a crucial driver of export performance in the field of energy technologies

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

simon kuznets sectoral shares in labor force a different explanation of his i s a ratio in estimating intersectoral productivity differences kuznets concludes that per worker product in agriculture is significantly lower than in industry and services agriculture s productivity backlog is explained by labor market failure especially in developing countries structural dualism however by analyzing agriculture as an economic activity organized by farm households competing with off farm and household production efficient allocation of resources in agriculture can be demonstrated therefore productivity measurements based on the concept of the farm as a firm are misleading a model of the farm household and empirical evidence are presented in his seminal book economic growth of nations simon kuznets 1971 has systematically analyzed intersectoral productivity differences to be observed in almost all countries with respect to labor productivity in agriculture a as compared to industry and services i s he has found out that per worker product in the a sector is significantly lower than in the i s sector and intersectoral inequality in per worker product is greatest at the low per capita product levels and smallest at the high per capita product levels p 236 hollis chenery and moises syrquin 1975 p 53 have confirmed but somewhat modified kuznets findings by explaining that relative labor productivity in the primary sector falls from about 70 percent to 50 percent at an income level of 500 and then gradually rises as agricultural technology is modernized and the surplus agricultural labor is absorbed by the rest of the economy as far as developing countries are concerned kuznets p 156 illustrates this explanation by the most plausible combination of economic determinants affecting an absolute decline in per worker product in the a sector resulting from increased pressure of population on land under conditions of relatively stagnant agricultural technology and some rise in per worker product in the i s sector resulting from a growth of modern components in industry and services in discussing several explanations of intersectoral differentials in per worker product p 238 kuznets finally comes to the conclusion that whatever the formulation the discussion tended justifiably to emphasize various aspects of duality in structure in the less developed countries p 247 he thereby confirms the dogma of structural dualism as the main source of disguised unemployment in agriculture seen as the cornerstone of the theory of development of underdeveloped countries since the 1940s according to paul rosenstein rodan 1957 p 1 already in 1954 arthur lewis has generated a micro model of agriculture within economic development with unlimited supplies of labour 1954 which during following years has been extended and modified by various development economists 2 with respect to developed professor of agricultural economics university of gottingen federal republic of germany platz der gottinger sieben 5 d 3400 gottingen the author acknowledges helpful comments of two unknown referees to an earlier draft of this article wide ranging international differences in intersectoral productivity discrepancies have been already observed and discussed mainly with respect to agriculture by marc latil 1956 j r bellerby 1956 and colin clark 1957 but none of them has provided a consistent explanation therefore clark p 254 had to admit that no immediate deductions can be drawn from the data more recent information on far reaching sectoral productivity differences between oecd countries are provided by oecd see table 1 2various models of agriculture in a dual economy are discussed inter alia by hans bemd schafer 1983

green technologies and environmental productivity a cross sectoral analysis of direct and indirect effects in italian regions abstract this paper provides empirical investigation of the effects of environmental innovations eis on environmental performances as proxied by the environmental productivity ep measure we focus on sectoral environmental productivity of italian regions by exploiting the regional accounting matrix including environmental accounts regional namea patent applications have been extracted by the patstat database and assigned to the environmental domain by adopting different international classifications of green technologies the latest release of the oecd env tech indicators and the union of this with the previously established wipo green inventory econometric results outline that regions sectors characterized by higher levels of green technologies gts are those facing better environmental performance these positive effects directly stem from the introduction of gt in the same sector as well as from the introduction of gt in vertically related sectors

equilibrium and migration in dynamic models of housing markets abstract this paper presents a model of a regional housing market where households choose among competing employment opportunities offered by cities within a given system the equilibrium requirement imposed in the model requires that households be indifferent among all locations both within their current city and other cities within the region rather than in terms of exogenously determined utility or populations this construction allows the characterization of equilibrium in terms of potentially observable variables related to household income given that equilibrium can be defined in this more general manner it is natural to identify ways in which the predictions will differ from those generated by existing models capozza and helsley s j urban econ 28 1990 180 203 model of land conversion is evaluated in this context in this setting the option value associated with the ability to delay development depends directly on the degree to which the income processes are correlated across cities also increased idiosyncratic income risk does not necessarily lead to larger option values

regional income dynamics abstract this paper uses time series techniques to explore interregional links in regional per capita income growth the study examines annual data for the period 1929 to 1990 for the eight bureau of economic analysis bea regions impulse response functions and variance decompositions from an estimated structural vector autoregression reveal that important and highly persistent interregional spillovers exist moreover these spillovers tend to be geographically dispersed

environmental innovations and firm profitability unmasking the porter hypothesis we examine impacts of different types of environmental innovations on firm profits following porter s sci am 264 4 168 1991 hypothesis that environmental regulation can improve firms competitiveness we distinguish between regulation induced and voluntary environmental innovations we find that innovations which do not improve firms resource efficiency do not provide positive returns to profitability however innovations that increase a firm s resource efficiency in terms of material or energy consumption per unit of output have a positive impact on profitability this positive result holds for both regulation induced and voluntary innovations although the effect is greater for regulation driven innovation we conclude that the porter hypothesis does not hold in general for its strong version but depends on the type of environmental innovation our findings rest on firm level data from the german part of the community innovation survey 2008 cis 2008
