innovation behaviour and regional indigenous potential meyer krahmer f 1985 innovation behaviour and regional indigenous potential reg studies 19 523 534 this paper has been written in order to present empirical results about some hypotheses not yet very well clarified in innovation oriented regional research the first part relates to one of the assumptions underlying innovation oriented regional policy which is that innovating and non innovating firms have different characteristics with respect to employment product lines and markets in particular the contribution to regional growth made by innovating firms is said to be larger in the second part of the paper the results of a study are presented in which it was attempted to find out empirically the extent of regional differences in indigenous innovation potential in the federal republic of germany reference is made to the innovating firms their performance and behaviour and bottlenecks in innovation as in other recent studies it is confirmed that there exists also in rural regions a sizeab

public research and industrial innovations in germany this paper deals with the effects of publicly funded research at universities polytechnics and federal research labs on industrial innovations in germany we discuss the characteristics of companies that benefit from the findings of public research institutions in questioning 2 300 companies we found that less than one tenth of product or process innovating firms introduced innovations between 1993 and 1995 that would not have been developed without public research these new products amount to approximately 5 percent of all new product sales regressions show that firms own r d support the ability to absorb the findings of public research and turn them into innovations contrary to the widely held opinion that proximity to public research institutions does promote collaboration between firms and public research and increase the amount of received knowledge spillovers we found no higher probability of publicly supported innovations for firms in germany that are located near universities or polytechnics

innovation and regional growth in small high technology firms evidence from britain and the usa oakey r p 1984 innovation and regional growth in small high technology firms evidence from britain and the usa reg studies 18 237 251 this paper examines the varying impact of regional resources on innovation in small high technology firms evidence is drawn from diverse local economies ranging from the development region of scotland through the south east of england to the bay area of california measurement focuses on the key inputs to innovation of research and development and investment capital surprisingly the findings indicate encouraging small firm innovation and growth in scotland an anticipated higher incidence of venture capital funding in the usa is confirmed and quantified with concluding comments on the policy implications resulting from this discrepancy

a non radial dea approach to measuring environmental performance data envelopment analysis dea has gained great popularity in environmental performance measurement because it can provide a synthetic standardized environmental performance index when pollutants are suitably incorporated into the traditional dea framework past studies about the application of dea to environmental performance measurement often follow the concept of radial efficiency measures in this paper we present a non radial dea approach to measuring environmental performance which consists of a non radial dea based model for multilateral environmental performance comparisons and a non radial malmquist environmental performance index for modeling the change of environmental performance over time a case study of oecd countries using the proposed non radial dea approach is also presented it is found that the environmental performance of oecd countries as a whole has been improved from 1995 to 1997

issues in measuring industrial r d abstract effective government science and technology policy requires a reliable database on industrial innovation this paper examines a number of issues concerning the measurement of industrial r d by analyzing the relationship between data reported in the nsf census rd 1 survey the basis for the official government r d statistics and data reported in two other sources firms 10 k reports and a federal procurement database we advance and test a hypothesis which accounts for systematic discrepancies between rd 1 and 10 k based estimates of company r d we also develop estimates of the extent of measurement error reflected in the various measures of r d and suggest some modifications to the rd 1 survey

accounting for change in national systems of innovation a friendly critique based on the u s case abstract this paper advances a friendly critique of the national systems of innovation approach and offers some suggestions for its future development i argue that the approach has difficulty accounting for bounded change in national systems i review three recent changes in the u s innovation system the internet boom and bust of the late 1990s and early 2000s the response to the terrorist attacks of september 11 2001 and the acceleration of productivity growth since the mid 1990s in order to assess the strengths and weaknesses of the framework in this respect future research might be enriched at least in the case of large national innovation systems by absorbing concepts developed in other strands of institutionalist literature such as intercurrence and embeddedness

antitrust and technological innovation in the us ideas institutions decisions and impacts 1890 2000 abstract the history of antitrust policy in the us as it relates to technological innovation exhibits major swings every few decades between favoring concentration and favoring deconcentration this paper sketches for each period the contending ideas that frame antitrust technology policy debates the salience of these ideas in the larger antitrust policy process the institutions for agenda setting and decision making in this area the policy decisions themselves and more speculatively the impacts of these decisions on technological innovation and industrial development the paper concludes with a preliminary attempt to identify the cyclical secular and static processes that have shaped the history of this policy area and to use this analysis to inform future policy makers

solving consumption and portfolio choice problems the state variable decomposition method we develop a new solution method for a broad class of discrete time dynamic portfolio choice problems the method efficiently approximates conditional expectations of the value function by using i a decomposition of the state variables into a component observable by the investor and a stochastic deviation and ii a taylor expansion of the value function we illustrate the accuracy of the method in handling several realistic features of portfolio choice problems such as intermediate consumption multiple assets multiple state variables portfolio constraints non time separable preferences and nonredundantendogenous state variables we finally use the method to solve a realistic large scale life cycle portfolio choice and consumption problem with predictable expected returns and recursive preferences jel g11 g12

dynamic portfolio choice with parameter uncertainty and the economic value of analysts recommendations we derive a closed form solution for the optimal portfolio of a non myopic utility maximizer who has incomplete information about the alphas or abnormal returns of risky securities we show that the hedging component induced by learning about the expected return can be a substantial part of the demand using our methodology we perform an ex ante empirical exercise which shows that the utility gains resulting from optimal allocation are substantial in general especially for long horizons and an ex post empirical exercise which shows that analysts recommendations are not very useful

carbon weighted economic development performance and driving force analysis evidence from china based on a data envelopment analysis framework this study develops an indicator termed as carbon weighted economic development cwed covering the dimensions of energy environment economy and resources to measure the economic development performance in a carbon emission conscious economy as an empirical application the proposed approach is applied to a case study of 30 provinces in china in addition to identify the driving forces underlying low carbon economic development in china we analyze the endogenous interactions and dynamic behaviors between cwed foreign direct investment foreign trade industrial structure local fiscal expenditure and energy consumption structure using a panel vector auto regression model the main findings show that 1 adjusting industrial structure by vigorously developing the service industry and reducing the coal energy share in the primary energy consumption structure are the two most effective approaches to improve cwed in both the short run and long run in return cwed has positive feedback effects on both approaches in the long run 2 increase of the fiscal expenditure has a short term positive effect on cwed 3 fdi has an indirect negative effect on cwed in the long run and foreign trade has an indirect positive effect on cwed in the short term

the eco efficiency of pulp and paper industry in china an assessment based on slacks based measure and malmquist luenberger index abstract china has become the world largest paper and paperboard producer however pulp and paper industry has involved high resource consumption and severe pollution especially for water this research has assessed the eco efficiency of china s pulp and paper industry at the national level and provincial level an overview regarding the cleaner production of china s pulp and paper industry was presented to reveal the measures for reducing environmental impact in the last two decades slacks based measure was used to analyze the efficiency levels of 16 provinces pulp and paper industries to uncover the underlying causes of eco efficiency performance malmquist luenberger index was calculated to discover the drivers of productivity growth of pulp and paper industries our results showed that the pollution treatment of china s pulp and paper industry has made progress in terms of water consumption and water pollution although the absolute amount of pollution discharge is still large chemical oxygen demand emissions are still the first critical influencing factor of pulp and paper industry s inefficiency furthermore efficiency progress was the dominating contribution of the industry s productivity growth between 2010 and 2013 the policies for adjusting the industrial structure of pulp and paper industry have resulted in the scale effects through eliminating backward production capacity and accelerating merger and acquisitions moreover the productivity of pulp and paper industry was underestimated when the undesirable outputs were ignored it indicates that the stricter environmental regulations have positive effects on paper companies to internalize environmental pressures in the production activities through environmental management in the future pulp and paper companies should further internalize the cost of pollution treatment through scale effects and technology improvement

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

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

government r d expenditure and space empirical evidence from five industrialized countries abstract in all industrialized countries several ministries pursue technology policies but only in germany and france are there special ministries for research and technology carrying out explicit technology policy in the usa great britain and france in particular public spending on defense is most relevant technologically in this study this kind of unintended technology policy will be referred to as implicit only a minor part of national r d activity is initiated with regional goals in mind the major part by far aims for national competitiveness the central hypothesis of this paper is that government r d spending generates unintended spatial effects which are far more consequential than the intended ones this study attempts to explain the phenomenon the technology policies of the five major industrialized countries usa germany japan france and great britain will be analyzed and the general tendency of governments to spatially cluster their r d assistance will be discussed the empirical section of this paper focuses on the relationship between government r d spending and employment in the high technology sector

bayes stein estimation for portfolio analysis in portfolio analysis uncertainty about parameter values leads to suboptimal portfolio choices the resulting loss in the investor s utility is a function of the particular estimator chosen for expected returns so this is a problem of simultaneous estimation of normal means under a well specified loss function in this situation as stein has shown the clas sical sample mean is inadmissible this paper presents a simple empirical bayes estimator that should outperform the sample mean in the context of a portfolio simulation analysis shows that these bayes stein estimators provide significant gains in portfolio selection problems

policy review section in this policy review section gerry stoker of the institute of local government studies presents a critical review of the role of urban development corporations udcs in comparing the experience of the udcs consideration is given to the varying nature of the land and property market in each udc area to the relationship with local authorities and other local bodies and the regeneration strategies pursued by the udcs this is followed by an assessment of the impact of the udcs in economic social and political terms in the second article john britton of the university of toronto examines the theoretical case for interventionist public policies to assist the innovation process in small and medium sized enterprises these arguments are supported by a review of the experience of various national support programmes introduced in the uk in particular the manufacturing advisory service introduced in 1978 and the design advisory service launched in 1982

defence spending in the u k regions short j 1981 defence spending in the u k regions reg studies 15 101 110 this paper traces the incidence of defence expenditure in the regions of the united kingdom over the years 1974 1975 1977 1978 inclusive it examines contracts with industry and the expenditure resulting from the deployment of ministry of defence manpower this paper shows that significant differences exist between the levels of defence expenditure in the regions reflecting these two factors it concludes that the scope for using defence expenditure to influence regional income and employment is limited

government and the decentralization of r d abstract the purpose of this article is to show how costs and benefits of geographical decentralization of r d can be identified and compared the benefits for the region that receives r d activities are studied in section 2 they stem from the short run multiplier effect the amelioration of human capital and the possible modernization of the local industrial structure on the cost side examined in section 3 the observable impacts of the decentralization of r d concern the loss of returns to scale and urban economies of the production of the r d output it is shown in section 4 that the flows of costs and benefits must be discounted by the social cost of capital the main conclusion of this article is that the decentralization of r d in a large sparsely populated country entails social costs and this would weaken its competitive position in world commerce on the other hand the issue of decentralization is more crucial for small countries in terms of population and economic size than for large ones like the u s where critical masses of research efforts can be simultaneously attained in many fields and in many places

why firm size matters investigating the drivers of innovation and economic performance in new zealand using the business operations survey abstractthe performance of the new zealand nz economy is something of an enigma although ranked one of 144 countries for four important growth fundamentals nz is middle of the pack when it comes to economic growth productivity and process innovation using four iterations 2005 2007 2009 and 2011 of the business operations survey this research seeks to shed some new light on this conundrum by using a multivariate probit regression mvprobit approach applied to pooled samples in excess of 22 000 unit record observations of nz firms the results suggest that factors including firm size high perceived quality investment research and development rd while many external issues such as those related to geography market structure business environment have little influence at the firm level innovations in nz are highly dependent on the fi

environmental regulations environmental governance efficiency and the green transformation of china s iron and steel enterprises abstract based on micro level enterprise panel data from 2005 to 2014 a slack based global data envelopment analysis dea model and a global malmquist luenberger index model are used to calculate the environmental governance efficiency ege of china s iron and steel enterprises ises then the different effects of two types of environmental regulation on ege of china s ises are analysed the results show that the overall level of ege for china s ises has remained low over the past 10 years the total factor environmental governance efficiency tfege presents a decreasing trend from 2005 to 2014 and the decline in tfege is mainly attributed to the technical progress change index gtpch moreover the bootstrap dea method is used for bias correction and the correction efficiency values are all within the confidence interval improving the accuracy of ege evaluation the regression analysis results show that different types of environmental regulations exert heterogeneous effects on tfege the relationship between market incentive environmental regulation and tfege has an inverted u shaped implying that although market incentive environmental regulation may improve the tfege in the short term continuously increasing this intensity would inhibit it however command control environmental regulation and tfege have a positive but not significant relationship

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

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

equilibrium interest rates and multiperiod bonds in a partially observable economy this paper analyzes the market for financial assets in a production and exchange economy with several realized outputs and a single unobservable source of nondiversifiable risk the paper demonstrates that for a large class of diffusion outputs and preferences optimizing consumers first estimate the realizations of the unobservable factor and then use these estimates to determine portfolio and consumption rules moreover the explicit consideration of this unobservable productivity factor affects equilibrium demands and prices the equilibrium spot rate of interest emerges as the best estimate of the unobservable factor and multiperiod default free bonds arise as the optimal hedge for the unobservable changes of the stochastic investment opportunity set this paper analyzes the market for financial assets in a production and exchange economy with several realized outputs and a single unobservable source of nondiversifiable risk the paper poses and answers three questions 1 how do consumers determine equilibrium demands and prices when their investment opportunities are unobservable 2 in equilibrium what financial assets provide an optimal hedge for the

power industry restructuring and eco efficiency changes a new slacks based model in malmquist luenberger index measurement measuring variations in efficiency and its extension eco efficiency during a restructuring period in different industries has always been a point of interest for regulators and policy makers this paper assesses the impacts of restructuring of procurement in the iranian power industry on the performance of power plants we introduce a new slacks based model for malmquist luenberger ml index measurement and apply it to the power plants to calculate the efficiency eco efficiency and technological changes over the 8 year period 2003 2010 of restructuring in the power industry the results reveal that although the restructuring had different effects on the individual power plants the overall growth in the eco efficiency of the sector was mainly due to advances in pure technology we also assess the correlation between efficiency and eco efficiency of the power plants which indicates a close relationship between these two steps thus lending support to the incorporation of environmental factors in efficiency analysis

undesirable outputs in efficiency valuations abstract efficiency measurement is usually based on the assumption that inputs have to be minimized and outputs have to be maximized in a growing number of applications however undesirable outputs are incorporated into the production model which have to be minimized in this paper various approaches for treating such outputs in the framework of data envelopment analysis dea are discussed and the resulting efficient frontiers are compared new radial measures are introduced which assume that any change of the output level will involve both undesirable and desirable outputs

measuring macroeconomic performance in the oecd a comparison of european and non european countries abstract we study the macroeconomic performance of 19 oecd countries over the period 1970 1990 performance is defined in terms of the ability of a country s macroeconomic managers to provide four services to their citizens a high level of real gdp per capita a low rate of inflation a low rate of unemployment and a favorable trade balance we use linear programming techniques to construct a best practice macroeconomic performance frontier and to measure the performance of each country in each year relative to the frontier we then add two environmental disamenities carbon and nitrogen emissions to the service list and repeat the analysis to see if the performance rankings change throughout the analysis emphasis is placed on a comparison of the performance of 14 european oecd countries with that of five non european oecd countries we find that performance rankings do change and that the relative performance of the european countries declines when the environmental disamenities are added to the service list

federal r and d spending in the united states of america some impacts on metropolitan economies malecki e j 1982 federal r d spending in the unitd states of america some impacts on metropolitan economies reg studies 16 19 35 government r and d spending in the united states of america is highly concentrated in a small number of metropolitan areas the effects of this spending are conceptualized in the context of technological change and in terms of local income effects agglomeration and spin off processes and inter urban subcontracting linkages description of the location pattern of federal r and d spending reveals a highly agglomerated pattern in a few specialized urban regions inter urban linkages through subcontracting for r and d tend to link fewer urban areas than do non r and d linkages reinforcing the concentrated pattern income change in metropolitan regions appears to be negatively influenced by federal r and d suggesting that positive local effects are more likely derived from the more complex processes of agglomeration and spin off

dynamic portfolio optimization with transaction costs and state dependent drift the problem of dynamic portfolio choice with transaction costs is often addressed by constructing a markov chain approximation of the continuous time price processes using this approximation we present an efficient numerical method to determine optimal portfolio strategies under time and state dependent drift and proportional transaction costs this scenario arises when investors have behavioral biases or the actual drift is unknown and needs to be estimated our numerical method solves dynamic optimal portfolio problems with an exponential utility function for time horizons of up to 40 years it is applied to measure the value of information and the loss from transaction costs using the indifference principle

assessing the regional economic impacts of defense activities a survey of methods defense activities exercised in a specific region may alter the region s economic performance an accurate assessment of the potential economic impacts of defense activities is a valuable undertaking to enable regional planners to prepare for changes the variety in the methods among others input output models economic base models keynesian regional multipliers fixed effects estimators and case study approaches inspired by geography sociology and political science can pose a dilemma we detail the historical and theoretical background of each method as well as select exemplary cases where these methods were applied by examining old and new methods we aim to construct a typology that could be valuable to all stakeholders in this sense defense economics can also contribute to the allied social sciences by outlining evaluation methods that may be applicable to other fields

the u s national innovation system origins and prospects for change in recent years the concept of national innovation systems has attained considerable currency and interest although a precise definition of a national innovation system is difficult analyses of the japanese and u s national innovation systems have implicitly defined them as the array of public and private institutions and organizations within an economy that fund and perform rd nelson 1993 interest in national innovation systems stems in part from a growing acknowledgment of the contributions to national economic welfare of superior performance in the commercialization and adoption of new technologies this awareness in turn has been heightened by the innovative and economic strength of postwar japan

malmquist indices of productivity growth during the deregulation of norwegian banking 1980 89 productivity growth during the deregulation of the norwegian banking industry is studied within the framework of data envelopment analysis which explicitly allows for multiple outputs introducing malmquist indices for productivity growth total growth can be decomposed into frontier growth and change in each bank s distance to the frontier both the total growth index and its components can be consistently chained over time we find productivity regress at the average bank prior to the deregulation but rapid growth when deregulation took place deregulation also led to less dispersion of productivity levels within the industry

predictability in financial analyst forecast errors learning or irrationality in this paper we propose a rational learning based explanation for the predictability in financial analysts earnings forecast errors documented in prior literature in particular we argue that the serial correlation pattern in analysts quarterly earnings forecast errors is consistent with an environment in which analysts face parameter uncertainty and learn rationally about the parameters over time using simulations and real data we show that the predictability evidence is more consistent with rational learning than with irrationality fixation on a seasonal random walk model or some other dogmatic belief

are universities and university research under threat towards an evolutionary model of university speciation according to some universities and academic research are under threat as we move towards a more knowledge intensive economy academics face pressures to link their work more closely to economic needs with potentially adverse long term consequences this has been characterised as a fundamental change in the social contract between universities and the state with the latter now having more specific expectations regarding the outputs sought from the former others have described this as a transition from mode 1 to mode 2 knowledge production or in terms of the emergence of a triple helix relationship between universities government and industry this article critically examines these claims setting them in historical context we analyse the history of the university and its evolving functions as it responded to changing external demands adopting an evolutionary model we describe how different university species emerged and co evolved each with different emphases on the functions of teaching research and contributing to the economy and society turning to the current environment facing universities we identify the main drivers for change and assess their likely impact before arriving at conclusions about the future of the university and university research what we are witnessing today appears to be not so much the appearance of a new and hence worrying phenomenon but more a shift back towards a social contract for the university closer to the one in effect before the second half of the twentieth century one which as it did then may bring about the emergence of new university species

renewable energy policy and electricity restructuring a california case study abstract many countries are in the process of deregulating and restructuring their electric power industries although the introduction of retail competition may have negative impacts on the development of renewable energy a number of countries are establishing new programs to support these clean energy technologies in the united states debate has centered on three primary renewables support mechanisms 1 the renewables portfolio standard 2 programs funded by an electricity distribution surcharge and 3 voluntary renewable energy purchases by electricity customers via green power marketing california provides a good case study of the design of renewables support programs within industry restructuring because policymakers considered all three of these options during the state s restructuring proceedings moreover many of the same policy options design issues and political conflicts that have arisen in california are likely to recur in other states and countries some of the most important lessons from the california experience include 1 renewable energy and environmental advocates must clearly articulate the need and rationale for continued support of renewables 2 cost containment and competitive neutrality concerns must be addressed head on 3 combinations of policies are likely to be far more effective than any single renewables policy and 4 the effectiveness of renewable energy policies developed during the restructuring process will be strongly linked to their duration and stability

optimal consumption and portfolio policies when asset prices follow a diffusion process abstract we consider a consumption portfolio problem in continuous time under uncertainty a martingale technique is employed to characterize optimal consumption portfolio policies when there exist nonnegativity constraints on consumption and on final wealth we also provide a way to compute and verify optimal policies our verification theorem for optimal policies involves a linear partial differential equation unlike the nonlinear partial differential equation of dynamic programming the relationship between our approach and dynamic programming is discussed we demonstrate our technique by explicitly computing optimal policies in a series of examples in particular we solve the optimal consumption portfolio problem for hyperbolic absolute risk aversion utility functions when the asset prices follow a geometric brownian motion the optimal policies in this case are no longer linear when nonnegativity constraints on consumption and on final wealth are included by these examples one can see that our approach is much easier than the dynamic programming approach

self selection and analyst coverage this paper examines the relation between analysts information about a stock s future prospects and their decisions to issue investment recommendations and earnings forecasts for that stock and the implications of this relation for the observed distribution of recommendations and earnings forecast errors articles in the financial press have long argued that analysts are reluctant to issue unfavorable investment information perhaps because they fear jeopardizing potential investment banking

effects of government financial incentives on firms innovation performance in china evidences from beijing in the 1990s abstract the purpose of this paper is to investigate the effects of chinese government financial incentives on firms innovation performance during the nation s initial economic transition period in the mid 1990s through a large scale empirical survey of more than 1000 chinese manufacturing firms the empirical evidences show that whereas the major government financial incentives such as special loans and tax credits were positively influential to innovative economic performance of firms direct earmarks not only failed to enhance innovative economic performance it sometimes negatively affected it surprisingly the findings show that all financial incentives of governments were unrelated to the patents of either high tech or general firms and direct earmarks affected the patents of these firms negatively although not to a significant degree this indicates that the centrally planned funding system of the 1990s was ineffective for enhancing technological progress for chinese manufacturing firms the study results imply that the chinese government should further increase the role of market force in its reforms a more market driven model by developing more s t initiatives to match the strategic directions of different enterprises particularly soes is recommended

space time patterns of entrepreneurial expectations and performance nijkamp p rouwendal j and van der ede m 1993 space time patterns of entrepreneurial expectations and performance reg studies 27 1 11 economic research in the past decade has paid much attention to the motives of entrepreneurial behaviour in a neo schumpeterian spirit entrepreneurial decisions are by definition characterized by uncertainty regarding future events rational expectations theories have become a major new line of thought in dealing with future uncertainty in the literature we find mainly attempts to estimate indirectly relationships on observable behaviour and strategies which are derived from postulated expectations of decision makers normally such expectations are not directly observed in our paper we have analysed a set of empirical regional micro data on entrepreneurial expectations regarding their future decisions whilst for the same period the observed and realized data are also available this allows for a test between expectations and realizations the paper develops

a review of literature and hypotheses on new technology based firms abstract this paper examines the existing literature on new technology based firms in an attempt to understand how such companies contribute to the vitality of an economy and to see which variables are critical in enabling them to do so from recent research efforts we have drawn together a set of hypotheses and organized them around four central questions 1 what do new firms contribute to the economy 2 what factors contribute to the success of such enterprises 3 in what cultural contexts do new businesses succeed and 4 which government policies are effective in stimulating and supporting new companies we found that existing studies suggest 1 that new technology based firms contribute significantly to an economy in terms of exports employment taxes paid research and development and innovations 2 that the founders of these new businesses tend to have a strong entrepreneurial heritage a development rather research oriented background and a high need to achieve and are young and highly educated 3 that sector differences may be a more important influence on company location than are regional policies and 4 that no one government program has proven itself to be more than marginally successful in stimulating industrial innovation

route 128 the development of a regional high technology economy abstract a corner of massachusetts not far from boston s route 128 has become a world center of high technology hundreds of enterprises mainly in electronics based industries employ over 250 000 people 75 000 of whom were added between 1975 and 1980 enterprises founded after world war ii have spearheaded growth in the state with a rapid rate of new firm formation continuing through the 1970s this paper examines the state s high tech growth to determine what caused it to happen where it did and assess the special role of new enterprises in promoting it the development is found to have been largely indigenous and spontaneous rather than the result of a concerted effort to attract industry massachusetts distinguished universities and their research laboratories an inherited technological infrastructure the importance of agglomeration externalities and the good fortune of having a home grown firm become the world s leading manufacturer of minicomputers were major contributors to the state s success but the enormous opportunities for new enterprises which the electronics revolution generated and the tendency for such firms to start up mainly as spin offs from other high tech firms or from university laboratories and to remain close to their sources fueled the tendency towards spatial concentration

regularities in the growth of high technology industries in regions abstract this paper aims to identify regularities in the growth of high technology industries in regions or synonymously regional high technology abbreviated as rht hereafter re viewing past studies a number of hypotheses as to what affects the growth of rht are presented and examined by various statistical methods a hypothesis on the self reproductive effect is supported most strongly the relationship of the self reproductive effect with the cumulative advantage effect is discussed as policy implications of the analyses it is advised for local governments 1 to base short term rht policies on the present state of rht or more specifically to expand currently forte fields of ht toward the specialisatin among regions instead of the current trend that every region follows the same rht policy and 2 to maintain or improve intellectual potential in the regions for long term rht policies or more specifically to improve middle education and to form a regional cultural policy rather than costly investment for science technical universities or public r d institutes

government research establishments state capacity and distribution of industry policy in britain heim c e 1988 government research establishments state capacity and distribution of industrial policy in britain reg studies 22 375 386 location decisions concerning government research establishments are examined to understand why defence and civil establishments were concentrated in the south in the late 1940s when regional policy to disperse economic activity was being actively promoted by the labour government world war two while increasing state capacity generally strengthened individual departments within central government with opposing views on regional policy thus having both positive and negative implications for pursuit of particular policies such as distribution of industry defence departments and the department of scientific and industrial research favouring southern locations generally prevailed over the board of trade the major exception the national mechanical engineering laboratory sent to scotland owed its location to political pressure more difficult to mobilize for oth

optimal portfolio choice under incomplete information models of asset pricing generally assume that the variables which characterize the state of the economy are observable however the distributional properties of asset prices that are relevant for portfolio decisions are in general not observable and therefore must be estimated the estimation of expected returns is a particularly difficult problem and estimation errors are likely to be substantial in this light it is reasonable to examine whether the assumption of observability of expected returns and other relevant state variables causes significant mis specification in equilibrium models of asset prices this paper has three main objectives first to derive optimal estimators for the unobservable expected instantaneous returns using observations of past realized returns second to establish that estimation and portfolio choice can be solved in two separate steps third to analyze the impact of estimation error on investment choices the estimators of expected returns are in general not consistent i e the estimation error does not tend to disappear asymptotically the effects of the estimation error therefore cannot be ignored even if realized returns are observed continuously over an infinite time period

the geography of innovation in small and medium sized firms in west germany since the 1980s a more micro economic oriented view has settled the dispute between macro economic theories over the causes of regional development differentiated studies revealed an unequal spatial distribution of r d laboratories and innovating firms and furthermore it was discovered that the innovation behaviour of firms differs between types of regions however these studies still left several questions unanswered

the static and dynamic environmental efficiency of renewable energy a malmquist index analysis of oecd countries abstract in recent years renewable energy and environmental efficiency have been interesting issues for both academics and industry actors when discussing sustainable development against this background the present study examines the environmental efficiency of renewable energy from the static and the dynamic perspective in 31 oecd countries a study conducted to understand the impact of renewable energy across countries as a non parametric methodology data envelopment analysis is used to measure environmental efficiency through multiple inputs and outputs labor capital and renewable energy supply are the three inputs while gdp is the desirable output and carbon emissions are the undesirable output to measure the dynamic environmental efficiency of renewable energy the malmquist productivity index is applied to estimate the average efficiency change from 2004 to 2011 the results demonstrate geographical differences in environmental efficiency across the oecd countries in oecd america have the highest average environmental efficiency and those in oecd europe have the largest standard deviation we also find that dynamic efficiency is influenced by the global financial crisis triggered in the united states further we show that oecd countries implement both catch up and frontier shift strategies to improve environmental efficiency

recent results in measuring innovation output abstract the fraunhofer institut fur systemtechnik und innovationsforschung isi is at present engaged in evaluating a number of technology policy programs designed to promote research development and innovation in small and medium sized firms these studies try to determine the extent to which these programmes have an impact upon the innovative activities of firms in this connection it was also attempted to measure the innovation output the level of innovation of a firm is innovation ouput the level of innovation of a firm is procedure involves a number of problems self assessment of firms in view of insufficient market transparency distortion due to self portraits reflecting the firms own interests we tried to mitigate such distortions by two approaches firstly firms were asked for their technologically new products the term new being applied a to the firm and b to the areas of product application as a result of this two tier procedure firms supplied rather realistic answers secondly supplementary questions were asked about sales figures the competitive technological situation nationally and internationally expenditure on r d patents stages of innovation aims of innovation etc the paper presents the results obtained to date on the innovation output of firms within the framework of an evaluation of the largest programme at present devoted to promoting r d and innovation in small and medium sized firms the results are based on a representative sample of approximately 4 500 small and medium sized firms up to 1 00 employees with r d activities in the federal republic of germany

posterior predictive and utility based approaches to testing the arbitrage pricing theory abstract to provide a framework for judging the economic significance of departures from the arbitrage pricing theory we adopt a utility based metric based on optimal portfolio choices this measure is examined using both predictive and posterior analysis our predictive analysis shows very large and economically significant departures from the model restrictions however the high level of parameter uncertainty suggests that we cannot conclusively either affirm or reject the apt our conclusions differ markedly from other studies which employ traditional significance testing procedures and in many instances fail to reject the apt restrictions

expected life time utility and hedging demands in a partially observable economy this paper analyzes the expected life time utility and the hedging demands in an exchange only representative agent general equilibrium under incomplete information we derive an expression for the investor s expected life time utility and analyze his hedging demands for intertemporal changes in the stochastic unobservable growth of the endowment process and the changing quality of information regarding these changes the hedging demands consist of two components which could work in opposite directions so that a conservative consumer may end up having positive hedging demands our results are qualitatively different from those prevailing under constant growth cf brennan m j 1998 the role of learning in dynamic portfolio decisions european finance review 1 295 306 ziegler a 2003 incomplete information and heterogeneous beliefs in continuous time finance springer berlin chapter 2

eco efficiency outcomes of mergers and acquisitions in the european electricity industry abstract the european electricity industry was recently liberalized in response there was a surge of mergers and acquisitions m as this study addresses the effects of m as on the eco efficiency of european electricity producers in 2005 2013 the environmental production technology comprises co2 emissions as an undesirable output i compute eco efficiency using data envelopment analysis dea and the malmquist luenberger productivity index which are both based on radial directional distance function i observe a decreasing trend in average eco efficiency which contradicts the previously documented moderate efficiency gains of liberalization the effects of m as are isolated using second step fractional regression the domestic horizontal m as which are systematically regulated by the european commission have no impact although one cross border horizontal deal has a same year effect of roughly 3 this effect becomes approximately 1 5 over a two year timespan vertical domestic m as have a short run negative impact of 3 6 that does not persist over time vertical international m as reduce the eco efficiency by 2 1 two years after their completion limited evidence suggests that the conglomerate deals are at least not harmful the policy implication is that the merger regulation should be based on dea eco efficiency measures regulators should devote more attention to cross border m as and particularly to vertical deals

sustainability of energy production and use in iran abstract the issue of oil and gas policies in iran is rather complex in the present investigation it is aimed to formulate plans for increasing the capacity of the country s energy production analysis of energy consumption pattern over last decades is indicative of inefficient usage the low energy prices in iran do not reflect economic costs further distortions exist in the tariff structures of most energy sources and in their relative prices it is recognized that price reform is a key policy element for promotion of energy conservation and fuel substitution with renewable energies mitigation policies in the energy sector are crucial to iran s overall policies emission of greenhouse gases can be reduced from 752 156 to 560 791 gg co 2 equivalents in 2010 by implementing the policies proposed for the energy sub sectors enhancing energy efficiency including combined cycle power generation has proved to be the most economic option for greenhouse gases reduction in energy sector iran s energy consumption pattern is unsustainable and consumption oriented

science technology and regional economic development review and prospects abstract this paper reviews the literature on the location and regional effects of science and technology st these pools of mobile workers are most attracted to large urban areas in only some of these areas however does the spin off process result in the generation of new technology based firms the availability of local venture capital appears to be the principal influence on this variation government policy regarding science and technology has impacts on regions by contributing to the agglomeration of r d government policy also often fails to recognize that s t policy and industrial policy have regional effects that may be long term in nature and most detrimental to those regions whose economies are least competitive finally some priorities for future research on innovation in a regional setting are identified

impacts of government incentives towards industrial innovation an analysis of the federal programme funding r d personnel in the federal republic of germany abstract against a background of deteriorating national and international economic conditions increasing importance is being attached by political administrations to the innovative capacities of small and medium sized firms with respect to the employment situation and to international competitiveness consequently government support of research development and innovation in these companies has taken a marked upward turn since the late seventies both in the federal republic of germany and in other industrialized western countries the actual impacts of some of these programmes are at present under study by the fraunhofer institut fur systemtechnik und innovationsforschung isi this paper is an outline of the results of a study of the largest current programme funding r d and innovation in small and medium sized firms by offering grants towards the costs of r d personnel the impact analysis is being conducted in two rounds the first round of studies which is the subject of this report took place in 1980 1981 and was designed to examine the discernible short term effects and characteristics of the programme the second round is planned for 1983 1984 as a summary of the impacts of the programme over the first five years of its term of effect the subjects of investigation are the quantitative and qualitative changes in r d activities caused by the programme in the firms under study and the contribution the programme can make to strengthen innovative and competitive capabilities the conditions underlying the programme are reviewed critically especially in order to see whether the barriers to innovation and the weak spots assumed did in fact exist in the firms examined the administrative management free rider effects and factors restricting impacts are investigated along with such questions as whether firms located in peripheral regions were reached by the programme to the same extent as firms in conurbation areas furthermore the reasons for non participation of firms are analyzed the example of the federal programme funding r d personnel thus is used in this impact analysis in an attempt to provide empirical data on the significance the range and the limits of such a government instrument promoting r d and innovation in small and medium sized firms

flexibility trap a case analysis of u s and japanese technological choice in the digital watch industry abstract this paper examines the widely shared belief that a flexible system of transactions is faster in adapting to major technological change than an inflexible system borrowing some ideas from elster ulysses and the sirens 1979 explaining technical change 1983 nuts and bolts for social sciences 1989 cambridge university press cambridge this paper contends that the flexible system may lead to a myopic selection of technology because it delays the technological turning point if the important part of the technological evolution is generated by the aggregation of the choice patterns of firms this paper investigates the case history of technological choice in the u s and japanese digital watch industries in the 1970s the paper s conclusions beg a reconsideration of current and previous thinking on industrial policy and technology strategy

asset pricing in a production economy with incomplete information this paper analyzes an economy in which investors operate under partial information about technology relevant state variables it is shown that for gaussian information structures under incomplete observations the consumer s problem can be transformed into an equivalent program with a completely observed state the conditional expectation of the underlying unobservable state variables a consequence of this transformation is that classic results in finance remain valid under an appropriate reinterpretation of the state variables the static capital asset pricing model capm of sharpe 24 lintner 16 and mossin 20 states that the expected premium on any risky asset is proportional to the premium on the market as a whole this theoretical linear relationship however is subject to criticisms on two grounds first it does not seem to be supported by the empirical evidence second it is based on the premises of a constant opportunity set merton 19 subsequently relaxes this assumption and shows that when the opportunity set fluctuates over time due to changes in the state of the economy individual securities are also priced with respect to selected portfolios funds providing a hedge against unanticipated fluctuations 2 more recently breeden 3 has extended merton s results by emphasizing the role of aggregate consumption in pricing relationships in this paper we seek to further our understanding of asset pricing by relaxing the assumption that investors observe the state of the economy in the mertonbreeden framework observed state variables affect the means and variances of asset returns implying deformations of the opportunity set over time from a practical point of view it seems that this complete information assumption is violated investors in financial markets operate under partial knowledge of the microvariables which influence production and the returns on assets their decisions rely mostly on information through noisy channels such as newspapers technical reviews or weather reports in this paper we attempt to model such

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

large firms in the production of the world s technology an important case of non globalisation us patenting by 686 of the world s largest manufacturing firms shows that their share of the world s production of technology is less than their share of r d activities and varies greatly amongst sectors in most cases the technological activities of these large firms are concentrated in their home country the characteristics of which influence the volume and trends in their technological activities much more strongly then the international component of these activities at the same time these large firms are major elements in the volume and the pattern of sectoral specializations in their home countries technological activities

towards an economic theory of the multiproduct firm this paper outlines a theory of the multiproduct firm important building blocks include excess capacity and its creation market imperfections and the peculiarities of organizational knowledge including its fungible and taut character a framework is adopted in which profit seeking firms are seen to diversify in order to avoid the high transactions costs associated with using various markets to trade the services of various specialized assets neoclassical explanations of the multiproduct firm are shown to be seriously deficient

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

eco efficiency analysis of power plants an extension of data envelopment analysis abstract in public discussion on environmental policy the notion of eco efficiency is often used the joint production of goods and undesirable outputs such as pollutants which may not be freely disposable without costs causes difficulties to measure the overall performance of the firm because of the absence of market prices for the undesirable outputs we are not able to estimate the environmental costs some of the measurement and evaluation difficulties can be overcome by employing data envelopment analysis dea as the efficiency measurement vehicle we propose the use of two different approaches in the first approach we start by decomposing the problem into two parts 1 the problem of measuring technical efficiency as the relation of the desirable outputs to the inputs and 2 the problem of measuring so called ecological efficiency as the relation of the desirable outputs to the undesirable outputs separately those two efficiency indicators are then combined in the second approach we treat pollutants as the inputs in the sense that we wish to increase desirable outputs and decrease pollutants and inputs the approaches are applied to the problem of measuring the efficiency of 24 power plants in a european country

dea approach for unified efficiency measurement assessment of japanese fossil fuel power generation this study discusses a new dea data envelopment analysis approach to measure the unified operational and environmental efficiency of energy firms it is widely known that they produce not only desirable good outputs e g electricity but also undesirable bad outputs e g co2 as a result of their plant operations the proposed approach incorporates an output separation desirable and undesirable outputs for the performance evaluation of energy firms in addition to the output separation this study separates inputs into energy and non energy inputs consequently the proposed approach incorporates not only the output separation but also the input separation within a computational framework of dea non radial measurement this study compares the proposed approach with other previous dea approaches used for the performance evaluation of energy firms after the methodological comparison this study applies the proposed approach for measuring the unified efficiency of japanese fossil fuel power generation this empirical study confirms that the implementation of kyoto protocol 2005 has not been effective on the unified efficiency of japanese fossil fuel power generation during the observed period 2004 2008 although the empirical result is inconsistent with the current japanese environmental policy under kyoto protocol it contains policy implications for guiding the future direction of japanese environmental policy on the electric power industry

environmental regulation and environmental productivity the case of china abstract constrained by the dual mission of supporting industrial growth and reducing emissions china s traditional emission reduction oriented environmental policies unavoidably face a dilemma this study adopts the gml index to calculate china s industrial productivity by considering environmental factors in addition based on the assumption of industry heterogeneity the author examines the non linear relationship between china s environmental regulation and environmental productivity and calculated the optimal regulation environment for industries according to this study when impact of undesirable outputs pollutant emissions is considered environmental regulation and environmental productivity are positively correlated which to some degree validates the porter hypothesis at present environmental regulation has significant positive effects on clean production industries but shows a lag effect on pollution intensive industries the degree of environmental regulation and environmental productivity show an inverted u shaped relation and display three thresholds it should be noted however that the relationship between regulation and productivity may vary across industries these findings have clear policy implications rather than continually increasing the level of environmental regulation the government should establish standards for individual industries that emphasize flexibility

u s technological leadership where did it come from and where did it go abstract during the quarter century following the second world war the united states was the world s most productive economy by virtually all measures and the technological leader across a very broad front this paper is concerned with the sources of u s technological leadership during that era and the reasons for the erosion of that leadership it is proposed that there were two distinguishable components of post war u s technological dominance one was a lead in mass production industries and this was of long standing the other was leadership in high technology industries due to massive american investments in science and technology eduction and research and development and this was new the u s advantage in mass production industries eroded when after bretton woods the world became a common market the u s preeminence in high technology industries diminished as other countries matched u s investments in science and technology it is argued that since the late 1960s the major industrial nations are bound together technologically as never before
