children as collective goods and divorce settlements the failure of many divorced fathers to comply with court mandated child support awards has been identified as a major reason why a growing number of children live in poverty in female headed households this paper presents a model that seeks to explain why so many divorced fathers allow their children s welfare to suffer as a consequence of divorce the point of departure is the recognition that children are collective consumption goods from the point of view of the father and mother within marriage proximity and altruism serve to overcome the free rider problem associated with the provision of public goods however on divorce the noncustodial parent suffers a loss of control over the allocative decisions of the custodial parent and it is not feasible for the couple to achieve a pareto optimal allocation of their joint resources a model of optimal marriage contracts is constructed in which a couple decides on the allocation of resources within marriage and on the terms of a settlement in the event

universities as strategic actors in the knowledge economy the university plays a particular role in the global knowledge economy as provider of both public and private goods related to education research and societal impacts at the same time universities in the plural play many different roles and exhibit a rich experimentation in organizational forms and knowledge foci adapting to local and global conditions there is also an aspect of uneven regional development and agglomeration of competencies as the individuals and organizations must also balance local interests and stakeholders with global networks in science technology and innovation thus we can identify empirically that universities are changing their strategies organizational structures and competencies in order to respond to new external demands and internal management practices bonaccorsi and daraio 2007 the question is how to explain this theoretically and identify empirical trends and pathways little previous research has focused upon how universities are learning to compete and why they try to act strategically this article as well as the selected articles in the special issue focus upon how and why this transition is occurring as well as the impacts for understanding universities as strategic actors in the knowledge economy section 2 provides an overview it introduces the three themes and articles collected in this special issue providing a summary of the main contributions section 3 then provides our perspective on how to analyze and understand universities as strategic actors it discusses relevant literature as a way of beginning to provide our perspective of the necessity and elements involved in a more united theoretical and empirical understanding this includes statement of predictions as well as empirical evidence that these trends are occurring section 4 concludes with relevant research themes for the future

reforming residential electricity tariff in china block tariffs pricing approach the chinese households that make up approximately a quarter of world households are facing a residential power tariff reform in which a rising block tariff structure will be implemented and this tariff mechanism is widely used around the world the basic principle of the structure is to assign a higher price for higher income consumers with low price elasticity of power demand to capture the non linear effects of price and income on elasticities we set up a translog demand model the empirical findings indicate that the higher income consumers are less sensitive than those with lower income to price changes we further put forward three proposals of chinese residential electricity tariffs compared to a flat tariff the reasonable block tariff structure generates more efficient allocation of cross subsidies better incentives for raising the efficiency of electricity usage and reducing emissions from power generation which also supports the living standards of low income households

determinants of import demand for non renewable energy petroleum products empirical evidence from nigeria abstract this study estimated determinants of import demand for refined petroleum products in nigeria for the period 1984 2013 it employed the autoregressive distributed lag ardl bounds test cointegration method and analysed both long run and short run determinants of import demand for total and specific petroleum products in the long run aggregate and sectoral incomes are significant determinants of import of refined kerosene further real effective exchange rate reer aggregate income gdp manufacturing sector s income domestic energy production dep and population growth rate pgr are drivers of import of refined motor spirit moreover reer dep and manufacturing sector s income are propellers of import of refined distillate fuel also reer and total output of petroleum products are major drivers of total import of refined petroleum products short run results show that previous period gdp pgr and manufacturing and service sectors incomes are determinants of import demand for refined kerosene moreover reer gdp previous pgr and manufacturing sector s income exert significant effects on the import of refined motor spirit further significant effects of reer dep previous pgr domestic output of the product and manufacturing and service sectors incomes on the import demand for distillate fuel were found policy implications of the foregoing are articulated in the paper

price and income elasticities of electricity demand evidence from jamaica abstract jamaica s electricity sector faces supply side challenges demand side policies have the potential to improve electricity use efficiency and reduce the likelihood of electricity disruptions in this paper i use the bounds testing approach to cointegration to obtain long run price elasticity of demand estimates for the period 1970 2014 the analysis focuses on aggregate electricity demand and three categories of consumers residential commercial and industrial the findings suggest that residential and industrial consumers are most responsive to price changes with long run price elasticities of demand of 0 82 and 0 25 respectively price based approaches are likely to be more successful in slowing electricity demand growth in these sectors

marriage divorce and asymmetric information we use data on people s valuations of options outside marriage and beliefs about spouses options the data demonstrate that in some couples one spouse would be happier and the other spouse unhappier outside of some marriages suggesting that bargaining takes place and that spouses have private information we estimate a bargaining model with interdependent utility that quantifies the resulting inefficiencies our results show that people forgo some utility in order to make their spouses better off and in doing so offset much of the inefficiency generated by their imperfect knowledge thus we find evidence of asymmetric information and interdependent utility in marriage

moving innovation systems research to the next level towards an integrative agenda the concept of innovation systems has been a guiding paradigm of innovation research and strongly influenced research and innovation policy since the early 1990s in spite of this success criticisms have been raised in recent years about whether it is still a suitable framework for addressing the innovation related challenges of the future in the present paper we claim that systemic explanations of innovation success have still a very important role to play in order to address the rising criticism however we have to reconsider the conceptual core of the family of innovation systems is approaches and sketch out a path for renewal the paper retraces the conceptual roots of is approaches assesses their uptake in different policy circles around the world discusses the conceptual core and explanatory ambition and finally formulates a future oriented research agenda for a more integrative innovation systems framework

the demand for residential electricity in south africa abstract this paper examines the residential demand for electricity in south africa as a function of real gross domestic product per capita and the price of electricity during the period 1978 2005 we make use of the bounds testing approach to cointegration within an autoregressive distributed framework suggested by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 3 289 326 following the literature we use a linear double logarithmic form using income and price as independent variables in the empirical analysis in the long run we find that income is the main determinant of electricity demand while electricity price is insignificant

cross subsidy in electricity tariffs evidence from india the recent reforms in india have been equated to the reduction of cross subsidization in electricity tariffs examining the usefulness of cross subsidies in electricity tariffs in india i have argued that they are prone to considerable inefficiencies and should be discontinued i have also formally examined the viability of above cost tariffs in the industrial sector to allow subsidized domestic and agricultural consumption finally i have used data from a distribution company in the state of uttar pradesh india to estimate industrial demand for electricity and have found that the policy of cross subsidy may have indeed gone overboard in india

consequences of a carbon tax on household electricity use and cost carbon emissions and economics of household solar and wind abstract the study was conducted to determine the consequences of a carbon tax equal to an estimated social cost of carbon of 37 2 mg on household electricity cost and to determine if a carbon tax would be sufficient to incentivize households to install either a grid tied solar or wind system u s department of energy hourly residential profiles for five locations 20 years of hourly weather data prevailing electricity pricing rate schedules and purchase prices and solar panel and wind turbine power output response functions were used to address the objectives two commercially available household solar panels 4 kw 12 kw two wind turbines 6 kw 12 kw and two price rate structures traditional meter smart meter were considered averaged across the five households the carbon tax is expected to reduce annual consumption by 4 4 552 kwh year for traditional meter households and by 4 9 611 kwh year for households charged smart meter rates the carbon tax increases electricity cost by 19 202 year for a household cost of 202 year the carbon tax is expected to reduce social costs by 11 annual carbon tax collections of 234 household are expected adding the carbon tax was found to be insufficient to incentivize households to install either a solar panel or wind turbine system installation of a 4 kw solar system would increase the annual cost by 1546 247 and decrease co 2 emissions by 38 2526 kg valued at 94 household the consequence of a carbon tax would depend largely on how the proceeds of the tax are used

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

dynamic demand for residential electricity in taiwan under seasonality and increasing block pricing abstract this paper studies the dynamic demand for residential electricity in taiwan employing a monthly panel data set composed of 19 counties and spanning the period from 2007 01 to 2013 12 the partial adjustment model used addresses the endogeneity of the electricity price that results from the increasing block pricing the estimated results show that there is a significant seasonal difference in the demand for electricity between the summer and non summer periods both the adjustment speed and own price elasticity during the summer months are found to be lower than those in the non summer months due to the hot weather in summer it is easier for consumers to adjust their electricity consumption in response to the changes in electricity pricing during the non summer time the estimated inelastic short run and long run income effects show that electricity is a necessity for consumers moreover the controversial electricity conservation policies are found to be ineffective measures for reducing electricity consumption in taiwan

the dynamics of electricity demand in pakistan a panel cointegration analysis abstract this paper examines the dynamics of electricity demand in pakistan at the aggregate and sectoral levels over the period 1978 2012 panel cointegration test and fully modified ordinary least squares method is employed to determine the long run relationship between electricity consumption real income real price of electricity and domestic price of non energy products the results reveal that electricity demand is more responsive to changes in income than changes in prices at the aggregate and disaggregate levels short run and long run income elasticities are positive and statistically significant supporting the conservation hypothesis it appears from the results that long run price elasticities are negative and significant at the aggregate level and for the agriculture commercial residential sectors and public utilities the short run price elasticities are significant but low in magnitude which implies that changes in electricity price exert minimal effect on the electricity consumption in pakistan the domestic price of non energy products is positive and significant for aggregate sample in the short run the domestic price of non energy products exert significant negative positive impact on electricity demand in the agriculture industrial sectors the results thus provide important information to the agents operating in the electricity market regarding the income and pricing policies and helps in planning the future strategy of electricity demand management

what is new in the new industrial policy a manufacturing systems perspective this paper explores the recent evolution of manufacturing related policies in leading oecd economies germany japan the united kingdom and the united states a novel framework the industrial policy matrix is introduced and then used to illustrate and compare policy approaches in terms of factor inputs intervention levels and degrees of coordination while approaches adopted in different countries vary reflecting their respective contexts there is some evidence of a convergence on the effectiveness of particular programmes and organizations as well as on the characteristics that support the competitiveness of national manufacturing systems including coordination and alignment of related policies partnerships with industry and longer term investment and planning

transfers among divorced couples evidence and interpretation we analyze divorce settlements made by a cohort of whites who graduated from high school in 1972 the effects of spouses incomes on the divorce transfer are estimated and used to simulate the welfare effects of divorce on husbands wives and children under alternative assumptions about marriage contracts and the ability of a couple to continue coordinating resources in the aftermath of divorce we find a positive negative relationship between divorce transfers and the growth of husband s wife s earnings during marriage the estimated expenditure on children in the divorce state is only half the accustomed level during marriage

household and industrial electricity demand in europe abstract this paper examines the electricity demand and its determinants in 29 european countries during the liberalization of the electricity market based on panel data for these countries for the years 1995 2015 and using a dynamic partial adjustment model price elasticities are estimated for both residential and industrial electricity demand these elasticities and effects of other variables on electricity consumption are estimated using both gmm generalized method of moments and ml maximum likelihood approaches it is found that the price elasticities are very small especially in the short run while the income elasticities are relatively large especially for households and in the long run

electricity demand for south korean residential sector abstract this study estimates the electricity demand function for the residential sector of south korea with the aim of examining the effects of improved energy efficiency structural factors and household lifestyles on electricity consumption in the study time series data for the period from 1973 to 2007 is used in a structural time series model to estimate the long term price and income elasticities and annual growth of underlying energy demand trend uedt at the end of the estimation period the result shows a long term income elasticity of 1 33 and a long term price elasticity of 0 27 with 0 93 as the percentage growth of uedt at the end of the estimation period this result suggests that in order to encourage energy efficiency in the residential sector the government should complement the market based pricing policies with non market policies such as minimum energy efficiency standards and public enlightenment

intra household allocation of resources inferences from non resident fathers child support payments a large proportion of divorced and separated fathers form new partnerships the new partner s preferences are not likely to put much weight on expenditures on the man s children from his previous union thus his own and his partner s income would have different impacts on his child support payments if partners relative incomes affect bargaining power in household decisions this article exploits within father variation in the british household panel survey 1991 2005 to estimate the impacts of the intra household income distribution on child support payments and the father s welfare we find that a higher share of father s income in household income increases the probability of paying child support and its amount relative to household income

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

examining behavioral patterns in household fuel consumption using two stage budgeting framework for energy and environmental policies evidence based on micro data from pakistan abstract prime objective of this study is to analyze fuel consumption patterns at national as well as at provincial level for pakistan dynamic patterns in household fuel choices have been examined under two stage budgeting framework through quadratic approximation of almost ideal demand system quaids using hies data for year 2015 16 to obtain reliable estimates of price and budget elasticities quadratic engel estimates reflect households energy expenditures allocation decisions while the probit estimates explore how alternate fuels are chosen by households for consumption the engel estimates highlight that the share of fuel expenditures in total household expenditures is higher in rural areas than in urban areas the computed compensated price elasticities suggest that firewood and kerosene are relatively more price inelastic in rural areas as compared to the urban areas furthermore our estimates also indicate that cleaner fuels are more price inelastic in urban areas than in rural areas with inter provincial variations in computed elasticities these estimates can be used as an effective policy making tool for transition towards cleaner fuels energy policy simulations to evaluate taxation and subsidy frameworks and energy system forecasting to prevent environmental degradation

modeling industrial energy demand in greece using cointegration techniques abstract this paper attempts to shed light on the determinants of industrial energy demand in greece for this purpose we used cointegration analysis in order to capture short run and long run elasticities for oil and electricity industrial demand respectively the sample spans the period 1970 2004 from the empirical analysis and the johansen s maximum likelihood procedure we found cointegration for oil and electricity demand the results suggest that industrial energy demand is inelastic both in the short and the long run while electricity and oil are substitutes also oil and electricity prices are weakly exogenous both in the short and the long run

a general model of r d competition and policy this article constructs a model of r d with heterogeneous firms each firm s probability of success is a function of its sunk and recurrent r d expenditures the social gains from an innovation are not fully captured by the successful firm the comparison of the social optimum and the market equilibrium involves balancing spillover and crowding effects pigovian corrective policies as well as strategic policies for a subset of colluding firms are discussed

triggers of change structural trajectories and production dynamics the transformation of production structures has been at the centre of the historical dynamics of capitalist economies since the first industrial revolution the article concentrates on production processes as principal loci of structural economic dynamics along increasing and decreasing returns trajectories these trajectories are triggered by structural opportunities and constraints embedded in production systems and their historical realisation is subject to different institutional configurations production units at different levels of aggregation the approach envisioned suggests the possibility of governing economic dynamics by structural policies working on the technological and organisational conditions of production as well as on the configuration of production processes within production units capitalist economies have to rely on a mix of co ordination devices across different production units and aggregation levels for capturing structural opportunities and avoiding structural constraints

systems thinking market failure and the development of innovation policy the case of australia innovation policy is increasingly informed from the perspective of a national innovation system nis but despite the fact that research findings emphasize the importance of national differences in the framing conditions for innovation policy prescriptions tend to be uniform justifications for innovation policy generally relate to notions of market failure that are applicable in all nations in all conditions in this paper we develop a broad framework for nis analysis involving free market coordination and complex evolutionary system approaches within this framework we explore the evolving relationship between market failure and systems approaches to innovation policy in the case of australia drawing on information and analysis collected for a major review of australia s nis and the government s 10 year plan in response to it we show how the free market trajectory of policy making of past decades is being extended complemented and refocused by new approaches to complex evolutionary system thinking these approaches are shown to emphasize the importance of systemic connectivity evolving institutions and organizational capabilities nonetheless despite the fact that there has been much progress in this direction in the australian debate the predominant logic behind policy choices still remains one of addressing market failure and the primary focus of policy attention continues to be science and research rather than demand led approaches we discuss how the development and elaboration of notions of systems failure rather than just market failure can further improve policy making in the future

carbon taxes and joint implementation an applied general equilibrium analysis for germany and india germany has committed itself to reducing its carbon emissions by 25 percent in 2005 as compared to 1990 emission levels to achieve this goal the government has recently launched an environmental tax reform which entails a continuous increase in energy taxes in conjunction with a revenue neutral cut in non wage labor costs this policy is supposed to yield a double dividend reducing both the problem of global warming and high unemployment rates in addition to domestic actions international treaties on climate protection allow for the supplementary use of flexible instruments to exploit cheaper emission reduction possibilities elsewhere one concrete option for germany would be to enter joint implementation with developing countries such as india where germany pays emission reduction abroad rather than meeting its reduction target solely by domestic action in this paper we investigate whether an environmental tax reform cum joint implementation ji provides employment and overall efficiency gains as compared to an environmental tax reform stand alone etr we address this question in the framework of a large scale general equilibrium model for germany and india where germany may undertake joint implementation with the indian electricity sector our main finding is that joint implementation offsets adverse effects of carbon emission constraints on the german economy ji significantly lowers the level of carbon taxes and thus reduces the total costs of abatement as well as negative effects on labor demand in addition ji triggers direct investment demand for energy efficient power plants produced in germany this provides positive employment effects and additional income for germany for india joint implementation equips its electricity industry with scarce capital goods leading to a more efficient power production with lower electricity prices for the economy and substantial welfare gains

the market failure and the systemic failure rationales in technological innovation systems abstract in this paper we analyse the conceptual relationship between the market failure rationale and the systemic failure rationale as justifications for policy intervention within an innovation systems is analytical framework current policy analyses in the is literature are characterised by two contrasting theoretical positions regarding the way in which both rationales are conceptually interrelated in one strand of the literature the market failure rationale is considered as a valid although insufficient justification for policy intervention that therefore needs to be complemented by the arguments put forward by the systemic failure rationale this perspective implicitly presents the systemic failure framework as a more general approach than the market failure perspective on the other hand a number of is policy contributions explicitly reject the market failure approach and consider it a flawed argument for government intervention in this theoretical view the systemic failure approach is thus proposed as a more appropriate alternative innovation policy rationale despite their relevance as the theoretical bases that currently underpin actual innovation policy design an analysis of the robustness and conceptual coherence of these contrasting perspectives has not been provided so far in this work we set the analytical steps we deem required for this analysis and investigate under which premises the relationship between the market failure and the system failure rationales proposed by these two policy perspectives is valid from a theoretical point of view

the relation between energy and non energy inputs in india s manufacturing industries the purpose of this paper is to examine the substitution possibilities among energy inputs and other non energy factors of production in response to price changes we relate this study to india s manufacturing industries this is of special interest since in the recent years indian industries have been gradually moving towards a high energy intensive structure of production in 1970 71 the mining and the manufacturing sector accounted for 52 9 per cent of the total commercial energy consumed in india in coal equivalent terms 8 p 1301 in this study we compute cross and own price elasticities of demand for all inputs a knowledge of the substitution possibilities is of paramount importance in economic planning consider for instance three situations first the effect of rising energy prices will tend to raise the demand for capital if capital and energy are substitute inputs second if energy and capital are complements the higher price for energy will tend to reduce the demand for both new capital equipment and energy thus the availability of cheap and ample supply of energy is significant in determining capital intensity and the future rates of capital formation in the literature on economic development this aspect of the choice of techniques has been by and large neglected third if there are limited substitution possibilities between energy and other inputs the adjustment by industry to higher prices of energy may be quite difficult and costs of production may rise precipitously necessitating a drastic change away from energy based production techniques in section ii of this paper we discuss the technique of analysis and describe the sources of data section iii presents the results and section iv is confined to the concluding remarks

technical change growth and trade new departures in institutional economics this article analyses the main theoretical and policy issues emerging from the literature on the evolutionary institutional economics of technical change the four distinguishing characteristics of which are that technology is often proprietary in nature only a part of knowledge is codifiable in handbooks blueprints patents and so on there are fundamental variations in the above two points across different technological fields and the evolution of knowledge is highly path dependent

analyzing the functional dynamics of technological innovation systems a scheme of analysis various researchers and policy analysts have made empirical studies of innovation systems in order to understand their current structure and trace their dynamics however policy makers often experience difficulties in extracting practical guidelines from studies of this kind in this paper we operationalize our previous work on a functional approach to analyzing innovation system dynamics into a practical scheme of analysis for policy makers the scheme is based on previous literature and our own experience in developing and applying functional thinking it can be used by policy makers not only to identify the key policy issues but also to set policy goals

elasticities of electricity demand in urban indian households abstract in the past several electricity demand studies have been published for india based on aggregate macro data at the country or sub national state level since the underlying theory of consumer demand is based on the behaviour of individual agents the use of micro data which reflects individual and household behaviour more closely can shed greater light on the nature of consumer responses in this paper seasonal price and income elasticities of electricity demand in the residential sector of all urban areas of india are estimated for the first time using disaggregate level survey data for about 30 000 households three electricity demand functions have been econometrically estimated using monthly data for the winter monsoon and summer season in order to understand the extent to which factors like income prices household size and other household specific characteristics influence variations observed in individual households electricity demand the results show electricity demand is income and price inelastic in all three seasons and that household demographic and geographical variables are significant in determining electricity demand

one price doesn t fit all an examination of heterogeneity in price elasticity of residential electricity in india abstract although well designed consumer electricity pricing can improve access contribute to higher metering increase penetration of energy efficient technologies limit extent of the rebound effect and influence viability of electricity distribution utilities in india there has been no comprehensive policy relevant assessment of price elasticities of electricity demand in the country the objective of this study is to estimate price elasticity of residential electricity consumption and disaggregate it by state rural and urban residence and income categories to provide evidence for electricity tariff setting in india we combine survey data from five rounds of nationally representative household consumption expenditure surveys covering the period 2005 2012 with administrative data on electricity deficit and improve on methods applied in previous studies by estimating price elasticities using a quadratic form to account for constraints in electricity supply we find that while the average price elasticity at the national level is 0 39 95 confidence interval 0 46 0 31 it varies significantly by state rural and urban residence and income categories our results indicate that a one price fits all policy may not be an effective approach to electricity tariff setting in india and a data driven understanding of heterogeneities in price elasticities can better inform residential electricity tariff design in the country

from simplistic to complex systems in economics the applicability of complex systems theory in economics is evaluated and compared with standard approaches to economic theorising based upon constrained optimisation a complex system is defined in the economic context and differentiated from complex systems in physio chemical and biological settings it is explained why it is necessary to approach economic analysis from a network rather than a production and utility function perspective when we are dealing with complex systems it is argued that much of heterodox thought particularly in neo schumpeterian and neo austrian evolutionary economics can be placed within a complex systems perspective upon the economy the challenge is to replace prevailing simplistic theories based in constrained optimisation with simple theories derived from network representations in which value is created through the establishment of new connections between elements

marital investments time consistency and emotions abstract a benchmark model of a married couple s educational investment yields an inefficient outcome due to the possibility of opportunistic divorce motivated by findings in social psychology i use psychological game theory to incorporate belief dependent guilt feelings multiple equilibria become possible some marriages have inefficient under investment some have efficient outcomes and preclude divorce if guilt is sufficiently important a life long efficient marriage is implied because a spouse may signal a trust so strong as to force the partner to hold beliefs that make divorce unattractive

energy models for demand forecasting a review abstract energy is vital for sustainable development of any nation be it social economic or environment in the past decade energy consumption has increased exponentially globally energy management is crucial for the future economic prosperity and environmental security energy is linked to industrial production agricultural output health access to water population education quality of life etc energy demand management is required for proper allocation of the available resources during the last decade several new techniques are being used for energy demand management to accurately predict the future energy needs in this paper an attempt is made to review the various energy demand forecasting models traditional methods such as time series regression econometric arima as well as soft computing techniques such as fuzzy logic genetic algorithm and neural networks are being extensively used for demand side management support vector regression ant colony and particle swarm optimization are new techniques being adopted for energy demand forecasting bottom up models such as markal and leap are also being used at the national and regional level for energy demand management

the australian growth miracle an evolutionary macroeconomic explanation an evolutionary macroeconomic approach is applied to explain economic growth in australia from 1901 to 2008 support is found for the hypothesis that there were two distinct developmental phases before and after world war ii the evidence suggests that in each phase growth followed an innovation diffusion trajectory made possible by a growing capital stock in the first phase capital equipment seems to have augmented labour while in the second it reduced labour inputs replaced by cheap fossil fuel inputs this allowed significant transfers of labour into an expanding service sector strong economies of scale were operative in both phases with labour hour inputs dominating in the first phase and fossil fuel consumption in the second the results indicate that the australian economy currently has very strong growth potential over the coming decade although its heavy reliance on fossil fuels is viewed as a threat in the medium term

modelling energy demand of developing countries are the specific features adequately captured abstract this paper critically reviews existing energy demand forecasting methodologies highlighting the methodological diversities and developments over the past four decades in order to investigate whether the existing energy demand models are appropriate for capturing the specific features of developing countries the study finds that two types of approaches econometric and end use accounting are commonly used in the existing energy demand models although energy demand models have greatly evolved since the early seventies key issues such as the poor rich and urban rural divides traditional energy resources and differentiation between commercial and non commercial energy commodities are often poorly reflected in these models while the end use energy accounting models with detailed sectoral representations produce more realistic projections as compared to the econometric models they still suffer from huge data deficiencies especially in developing countries development and maintenance of more detailed energy databases further development of models to better reflect developing country context and institutionalizing the modelling capacity in developing countries are the key requirements for energy demand modelling to deliver richer and more reliable input to policy formulation in developing countries

internalisation of external costs in the polish power generation sector a partial equilibrium model this paper presents a methodical framework which is the basis for the economic analysis of the mid term planning of development of the polish energy system the description of the partial equilibrium model and its results are demonstrated for different scenarios applied the model predicts the generation investment and pricing of mid term decisions that refer to the polish electricity and heat markets the current structure of the polish energy sector is characterised by interactions between the supply and demand sides of the energy sector the supply side regards possibilities to deliver fuels from domestic and import sources and their conversion through transformation processes public power plants public chp plants industry chp plants and municipal heat plants represent the main producers of energy in poland demand is characterised by the major energy consumers i e industry and construction transport agriculture trade and services individual consumers and export the relationships between the domestic electricity and heat markets are modelled taking into account external costs estimates the volume and structure of energy production electricity and heat prices emissions external costs and social welfare of different scenarios are presented results of the model demonstrate that the internalisation of external costs through the increase in energy prices implies significant improvement in social welfare

stable partnerships matching and local public goods abstract in the presence of local public goods differences in tastes are an important determinant of the way in which partnerships are formed heterogeneity in tastes for private vs public goods produces a tendency to positive assortment and partnerships of couples with similar tastes heterogeneity in tastes for different public goods brings about partnerships of couples with similar tastes only if there is a significant overlap in the distribution of tastes of the two groups to be matched we show that with two public goods we may get negative assortment pure positive assortment being only one of many possibilities

government policy university strategy and the academic entrepreneur the case of queensland s smart state institutes significant new university initiatives are usually analysed from the perspectives of government policy university strategy or the entrepreneurship of particular individuals but rarely from the view of their interdependencies this paper reports on the creation of four smart state institutes at the university of queensland in australia and the concatenation of circumstances decisions and actions that led to their formation in the course of just over a decade these institutes addressing biotechnology nanotechnology neuroscience and the molecular and cellular basis of disease have developed into a cluster of scientific research of global significance raising over 1 billion in investment and employing 1300 staff

household energy elasticities and policy implications for pakistan abstract this study estimates fuel expenditure and price elasticities of household fuels in pakistan the burning of biomass is harmful to health and the environment and may cause preventable morbidity and mortality it is important to investigate how households fuel choices are linked to prices so that governments can consider appropriate steps to enhance the consumption of clean fuels using three pooled cross sectional surveys from pakistan and applying the linear approximate almost ideal demand system la aids model we found that all fuel types except natural gas were price inelastic at the national level and for urban households in rural areas natural gas and lpg were found to be more price elastic compared to urban areas simple policy simulations based on our results suggest that in order to reduce indoor air pollution by encouraging the adoption of clean fuels lpg and piped natural gas governments should subsidies clean fuels rather than imposing taxes on solid fuels moreover in the case of pakistan a subsidy for lpg should be preferred over a subsidy for piped natural gas as it produces a more cost effective reduction in solid fuel use

changing the rules midway the impact of granting alimony rights on existing and newly formed partnerships this article analyses the effect of a reform granting alimony rights to cohabiting couples in canada a collective household model with a matching framework predicts that changes in alimony laws would affect existing couples and couples to be differently for existing couples it benefits the intended beneficiary but for couples not yet formed it generates offsetting intra household transfers and lower intra marital allocations for the beneficiary our empirical analyses confirm these predictions among couples united before the reform obtaining the right to petition for alimony led women to lower their labour force participation but not among newly formed cohabiting couples

review of key international demand elasticities for major industrializing economies abstract this paper conducts a selective review of various estimates for energy demand responses focused specially upon lower income industrializing economies rather than richer mature nations it emphasizes recent trends from empirical studies that have been published after 2000 emphasis is placed on the five major emerging or transitional economies in brazil china india mexico and russia although other important nations like chile and south korea are also discussed when studies are available the review focuses attention on the long run responses to changes in prices and income after capital stock turnover has been completed the terminology often refers to elasticities or the percentage change in energy use divided by the percentage change in price or income holding constant all other factors that could influence energy use decisions estimates cover petroleum products natural gas and electricity although the available studies often ignore coal they also include the economy wide impacts real gdp to price changes most studies have focused upon household and transportation use of liquid fuels many fewer studies have investigated fuels used by industry or commerce or for electric generation based upon the available estimates price and income elasticities for liquid fuels are generally less than one unity for many countries and sectors except for the long run income effect for transportation purposes which can range widely by country between 0 24 and 1 75 while averaging 0 94 for all countries

dynamic female labor supply the increase in female employment and participation rates is one of the most dramatic changes to have taken place in the economy during the last century however while the employment rate of married women more than doubled during the last 50 years that of unmarried women remained almost constant to empirically analyze these trends we estimate a female dynamic labor supply model using an extended version of eckstein and wolpin 1989 to compare the various explanations in the literature for the observed trends this dynamic model provides a much better fit to the life cycle employment pattern than a static version of the model and a standard static reduced form model heckman 1979 the main finding using the dynamic model is that the rise in education levels accounts for about 33 percent of the increase in female employment and the rise in wages and narrowing of the gender wage gap account for another 20 percent while about 40 percent remains unexplained by observed household characteristics we show that this unexplained portion can be empirically attributed to cohort specific changes in preferences or the costs of child rearing and household maintenance finally the decline in fertility and the increase in divorce rates account for only a small share of the increase in female employment rates

learning innovation increasing returns and resource creation luigi pasinetti s original sin of and call for a post classical economics we draw on the seminal contribution to economics by luigi pasinetti respond to his call to reverse what he saw as the original sin of classical economists exacerbated by neoclassical economists namely the assumption of non increasing returns to scale and move towards building a post classical economics we outline the contours of a post classical framework that draws on key themes and contributions from pasinetti on learning technical progress increasing returns resource creation trade and catching up and contributions from within and without economics that are in line with lend support to and challenge it we advocate the pressing need and opportune timing for a concerted effort to revitalise ideas from the once vibrant cambridge school of economics and help develop a fresh more pluralist and inclusive post classical economics that cuts across divides and opens up opportunities for a less dismal science

elasticities of electricity demand in india abstract the paper examines econometric relationship between electricity consumption and variables like income price of electricity and diesel used in for captive power generation to meet the shortages and reliability of power supply from utilities in five major consumer categories in india these categories are residential commercial agriculture small and medium industries and large industries income and price elasticities of electricity consumption are estimated at the national level for these consumers by pooling data across 19 states spread over 9 years 1985 86 1993 94 the results show that electricity consumption in commercial and large industrial sectors are income elastic 1 while residential agricultural and small and medium industries are income inelastic

technology systems and technology policy in an evolutionary framework the central purpose of this paper is to outline an evolutionary theory of technology policy and to connect it with the emerging literature on national systems of innovation any understanding of technology policy must be based on a clear understanding of the nature of technology and the important differences between science and technology technology can be treated in terms of knowledge skills and artifacts and in each case there are different variety generating mechanisms different selection processes and different institutional structures for policy purposes the degree of connection between these different dimensions of technology is at the core of technology policy c 1995 academic press inc copyright 1995 by oxford university press

evolution roots and influence of the literature on national systems of innovation a bibliometric account the literature on the national systems of innovation nsi is a relatively new field of research that has spread remarkably in the past 20 years this article offers a complementary quantitative description of the state of the art of the literature based on bibliometric methods by explicitly addressing the roots evolution and influence of nsi literature the exercise shows that over time the rate of published articles was quite irregular and that contributions on nsi have not yet converged to an integrated analytical framework although historically detailed descriptions on nsi showed a noticeable increase in the more recent period 2006 2010 analyses using more formal and diversified quantitative methodologies for assessing the performance of nsi remained lacking reflecting its persisting methodological weaknesses the roots of the nsi literature can be found at the core of innovation studies by certain well known scholars in the area of economics of innovation and science policy research even though publications on nsi are falling in relative importance and are highly concentrated on a small set of countries united kingdom denmark and the united states their influence is global they are cited by authors affiliated in organisations around the world notably in latin america and asia such an influence goes far beyond the area of innovation studies and has resonated in fields such as economic geography environmental studies international business and managerial sciences this demonstrates that the nsi literature is not self referential

the functions of technology infrastructure in a competitive economy abstract governments of industrialized nations play varied but important roles in providing the diverse technology infrastructure that supports a modern competitive economy an understanding of the structure and impacts of these roles as well as efficiency differences among alternative implementation schemes is particularly important at this time as competing industrialized nations are revamping their technology infrastructures in response to major shifts in thescope as well as the content of their growth strategies these shifts in scope can be described as evolutionary changes from single stage to multi stage strategies in that several modes of technology based competition are simultaneously pursued that is whereas an economy may have focused on innovation manufacturing high volume or niche markets etc most if not all of these must be pursued together in the future in order to diversify risk and achieve economies of scope effective implementation of the more complex multi stage growth strategy requires a consensus model of the appropriate functions for infrastructure and its institutions such a consensus model is necessary to efficiently guide strategic planning in both industry and government in particular a conceptual basis is needed for defining the critical interfaces between the government and industry roles including effective long range planning communication and cooperation the required technology infrastructure policy model is derived from a microeconomic model of the typical technology based industry existing national strategies have demonstrated the importance of efficiency at the production and market development stages as well as at the r d stage but the trend is towards promoting simultaneous efficiency at all these stages that is the model and the derived infrastructure functions must cover all stages and interfaces in the technology and related product life cycles

the evolution of technologies and investment in innovation the proposition that old knowledge is an input in the production of new knowledge is itself old knowledge in a general sense we all know that current innovations derive partly from past innovations and will themselves influence future ones but within a technology is there a time dependent pattern to innovations more specifically do the characteristics of innovations change systematically when compared to those that precede or follow them and are returns to investment in innovation and the consequent level of such investment dependent in a consistent way on the location of innovative effort in the evolution of a technology our analysis is partly motivated by an unresolved controversy in the economic literature between what may be characterised as the kuznets and the schmookler views of technical change it may therefore be helpful to review briefly the content of this debate kuznets i 930 and burns i 934 and later salter i 960 among others saw technological opportunities as declining over the life cycle of a new product or industry each new technology is limited in the extent to which it can be developed and the most promising opportunities for development are exploited first both kuznets and burns explained the eventual decline in the growth in output of new industries by a decline in the rate of technical change as a given technology matures kuznets stressed the role of price reducing changes in production processes as a force generating growth in output a reduction in the rate of such change he argued leads to a decline in the negative rate of change of the relative price of a new product and a consequent decline in the rate of growth of its output a parallel argument can be made for quality enhancing product innovations which contribute to the growth in demand for a new product as opportunities for the most important quality improvements are exhausted the growth rate in demand declines and the industry gradually approaches obsolescence as newer technologies emerge at the macroeconomic level it follows that both the rate of change in productivity and the growth of the economy depend upon the combination of new versus old industries that account for aggregate output this view of the evolution of technologies has been sharply criticised by schmookler i966 given the cost required to produce an innovation the profitability it contributes increases with market size the larger the demand the greater is the revenue collected from a new product or alternatively the larger is the aggregate cost saving from a superior production process it follows ceteris paribus that a larger market leads to an increase in investment in inno

developing science technology and innovation indicators what we can learn from the past the science technology innovation system is one that is continuously and rapidly evolving the dramatic growth over the last twenty years in the use of science technology and innovation sti indicators appears first and foremost the result of a combination between on the one hand the easiness of computerized access to an increasing number of measures of sti and on the other hand the interest in a growing number of public policy and private business circles in such indicators as might be expected in societies which increasingly use organised science and technology to achieve a wide variety of social and economic objectives and in which business competition is increasingly based on innovation as highlighted on the basis of 40 years of indicators work frontiers and characteristics that were important last century may well no longer be so relevant today and indeed may even be positively misleading

complex innovation policy systems towards an evaluation mix abstract the mix of contemporary innovation policies impacting on a given territory are typically characterised by quite different underlying rationales and instruments complexity is further increased by multi level considerations thus policies with different characteristics and from different administrative levels are continually interacting with one another in complex policy systems these interactions significantly complicate the evaluation of individual policies and raise a series of difficult questions around how their respective evaluation processes should interact to facilitate learning around the performance of policy systems this paper contributes with a simplified definition of an innovation policy system as the conjuncture of policy mix and multi level dimensions from which a series of steps are proposed for arriving at an evaluation mix relevant for the specific characteristics of a given policy space these ideas are explored with respect to the case of the basque country region of spain and signal an agenda for further applied policy research

estimation of urban residential electricity demand in china using household survey data abstract this paper uses annual urban household survey data of sichuan province from 2007 to 2009 to estimate the income and price elasticities of residential electricity demand along with the effects of lifestyle related variables the empirical results show that in the urban area of sichuan province the residential electricity demand is price and income inelastic with price and income elasticities ranging from 0 35 to 0 50 and from 0 14 to 0 33 respectively such lifestyle related variables as demographic variables dwelling size and holdings of home appliances are also important determinants of residential electricity demand especially the latter these results are robust to a variety of sensitivity tests the research findings imply that urban residential electricity demand continues to increase with the growth of income the empirical results have important policy implications for the multistep electricity price which been adopted in some cities and is expected to be promoted nationwide through the installation of energy efficient home appliances

short and long run electricity demand elasticities at the subsectoral level a cointegration analysis for german manufacturing industries in this paper we use multivariate cointegration analysis to estimate electricity demand elasticities at the subsectoral industry level this enables us to reap the benefits of lower heterogeneity within the electricity consuming sectors investigated and of retaining additional information otherwise blurred by aggregation the annual data set used covers eight subsectors of the german economy for the period 1970 2007 by employing a cointegrated var model specification and accounting for structural breaks we find cointegration relationships for five of the eight subsectors studied the long run elasticities range between 0 70 and 1 90 for economic activity and between 0 52 and zero for the price of electricity the short run elasticities are estimated by single equation error correction modeling and found to be between 0 17 to 1 02 for economic activity and 0 57 to zero for electricity price granger causality tests indicate that in the long term causality runs from both economic activity and electricity price to electricity consumption while granger causality from electricity price and electricity consumption to economic activity is detected in only two subsectors electricity price is found to be granger caused neither in the long nor the short run finally an impulse response analysis yields plausible results confirming the usefulness of the approach adopted

divorce and the cognitive achievement of children children of divorced parents exhibit lower test scores and educational attainment have these correlations a causal interpretation parents who divorce may be less likely to invest in their children while together or they may divorce to shield their children from the effects of marital conflict i study the relationship between children s achievement and the marital status of their parents within a dynamic framework in which partners decide on whether to remain married how to interact with or without conflict and child investments i then assess whether a child whose parents divorced would have been better off had divorce not occurred

the welfare effects of unprecedented electricity price hikes in zambia abstract this paper simulates the real household expenditure effects of large electricity price increases in zambia first we find that electricity subsidies are highly regressive the richest household quintile receives over 60 of the subsidies while the poorest quintile receives less than 1 second our partial equilibrium simulations of the welfare effects of a 75 electricity price increase show that the poorest households would experience a 3 times larger percentage loss in real expenditure compared to the wealthiest households naturally these adverse effects lead to an increase in poverty however we find that transferring the fiscal savings realised from the complete elimination of electricity subsidies to the poor reduces extreme poverty significantly this budget neutral strategy is particularly attractive for zambia and other sub saharan economies currently battling the twin challenges of widening budget deficits and high extreme poverty

a stackelberg model of child support and welfare this article models the child support and welfare decisions of never married parents on welfare as a stackelberg game the mother chooses whether to exit welfare report paternity and to obtain a formal child support order if a child support order is obtained the father chooses whether to comply with the order simulation results from the structural parameters indicate that increasing the child support disregard increases paternal compliance slightly and affects maternal paternity reporting more significantly effects are limited however by low paternal incomes results also indicate that high award amounts can decrease expected child support payments to women on welfare

regionally varying and regionally uniform electricity pricing policies compared across four usage categories the objective of our research is to predict how electricity demand varies spatially between status quo regionally uniform electricity pricing and hypothetical regionally varying electricity pricing across usage categories we summarize the empirical results of a case study of electricity demand in south korea with three key findings and their related implications first the price elasticities of electricity demand differ across usage categories specifically electricity demands for manufacturing and retail uses are price inelastic and close to unit elastic respectively while those for agricultural and residential uses are not statistically significant this information is important in designing energy policy because higher electricity prices could reduce electricity demands for manufacturing and retail uses resulting in slower growth in those sectors second spatial spillovers in electricity demand vary across uses understanding the spatial structure of electricity demand provides useful information to energy policy makers for anticipating changes in demand across regions via regionally varying electricity pricing for different uses third simulation results suggest that spatial variations among electricity demands by usage category under a regionally varying electricity pricing policy differ from those under a regionally uniform electricity pricing policy differences in spatial changes between the policies provide information for developing a realistic regionally varying electricity pricing policy according to usage category

estimation of elasticity price of electricity with incomplete information abstract the sharp increase in energy prices and growing concern for environmental issues among other things are behind the renewed interest in energy demand estimation however there is scarce academic literature that takes real situation of energy suppliers into account high quality but incomplete data in this paper we propose a useful and rather simple instrument for estimating electricity demand with the incomplete and or imperfect data currently available to suppliers in particular using real expenditure and consumption data on electricity we employ a model of random effects for panel data to estimate residential and industrial electricity demand in spain

sectoral systems of innovation and production the concept sectoral system of innovation and production provides a multidimensional integrated and dynamic view of sectors it is proposed that a sectoral system is a set of products and the set of agents carrying out market and non market interactions for the creation production and sale of those products a sectoral systems has a specific knowledge base technologies inputs and demand agents are individuals and organizations at various levels of aggregation they interact through processes of communication exchange co operation competition and command and these interactions are shaped by institutions a sectoral system undergoes change and transformation through the co evolution of its various elements 2002 elsevier science b v all rights reserved

independence of allocative efficiency from distribution in the theory of public goods when is the pareto optimal amount of public goods independent of income distribution subject to some regularity conditions the answer is when preferences of every individual i can be represented by a utility function of the form u x i y a y x i b i y where x i is i s consumption of private goods and y is the amount of public goods

competitiveness and industrial policy from rationalities of failure towards the ability to evolve this article elaborates a dynamic rationale of industrial policy focusing on how to strengthen the socio economic system s ability to evolve i e how to achieve high real income together with qualitative change it highlights that the ubiquitous rationalities of failure be it of markets governments or systems are rooted in a peculiar habit of accepting hypothetical perfect states as normative benchmarks in contrast a dynamic logic of intervention should start from the question what the system aims to accomplish combining the structuralist ontology of micro meso and macro with the functional principles of evolutionary change the paper proposes a general typology of economic policies based on their respective contributions to the system s ability to evolve

the family as the health producer when spouses act strategically the grossman model has been extended recently in order to take account of the fact that most people lead their lives in a family using frameworks in which family members respectively a have common preferences and b are nash bargainers these models however do not consider individual incentives for behaving strategically in the model presented in this paper spouses interact strategically both in the production of own health and in the production of health of other family members we analyse inter alia the impact on the distribution of health of changes in family policies such as child allowance and custody rules

demand elasticities in oecd dynamical aspects abstract four models with different lag structures are used to express final energy demand in oecd from 1960 1982 as a function of real gdp and average energy price the income and long run price elasticities are not significantly dependent on the model specification but the koyck lag scheme estimated in its distributed lag form is found to give the most satisfactory results the statistical properties of the data together with evidence of trends in the elasticities both suggest that the period of falling real prices prior to 1971 is not comparable to the present period for the period after 1971 an income elsticity of 1 02 and a long run price elasticity of 0 37 are obtained

testing viability of cross subsidy using time variant price elasticities of industrial demand for electricity indian experience abstract indian electric tariffs are characterized by very high rates for industrial and commercial classes to permit subsidized electric consumption by residential and agricultural customers we investigate the viability of this policy using monthly data for 1997 2003 on electric consumption by a few large industrial customers under the aegis of a small distribution company in the state of uttar pradesh for a given price cost ratio it can be shown that if the cross subsidizing class electricity demand is sufficiently elastic increasing the class rates fail to recover incremental cross subsidy necessary to support additional revenues for subsidized classes this suboptimality is tested by individually estimating time variant price elasticities of demand for these industrial customers using box cox and linear regressions we find that at least for some of these customers cross subsidy was suboptimal prior to as late as october 2001 when rates were changed following reforms

public policies and changing boundaries of firms in a history friendly model of the co evolution of the computer and semiconductor industries in this paper we explore the effects of alternative policies ranging from antitrust to public procurement open standards information diffusion and basic research support on the dynamics of two vertically related industries in changing and uncertain technological and market environments the two industries are a system industry and a component industry and the evolution of these industries is characterized by periods of technological revolutions punctuating periods of relative technological stability and smooth technical progress we have been inspired by the co evolution of the computer and component industries from their inceptions to the 1980s on the basis of that evolution we have developed a history friendly model this co evolution in sum this paper has stressed that various types of policies may sometimes have contrasting effects on the industry mainly on concentration and technical change and innovation it has also shown that the consequences of policies may spillover from one industry to another and from one type of firms to another policies that aim at a specific industry may provoke major changes in a related industry through the product market the changing boundaries of firms or knowledge and technological interdependencies the policy maker has to be aware of that finally a major point of the paper regards the unintended consequences of policies

goodwin cycles and the bopc growth paradigm a macrodynamic model of growth and fluctuations abstract the paper builds a non linear macrodynamic model to study the relation between the functional distribution of income technological progress and economic growth in the short term the interaction between the productivity regime the demand regime and the distributive conflict generates cyclical paths a la goodwin in the long term output growth rate is constrained by the balance of payments a la thirlwall in which the elasticities of foreign trade are modeled as a function of the complex relation between the wage share and the innovation capabilities of theeconomy

evolutionary economics and technology policy in this brief paper i propose to explore the economics of technology policy from an evolutionary perspective as with any evolutionary argument the central concern is with the mechanisms of economic change in this case in relation to the development of new technologies and patterns of organisation and their spread into the wider economic system in this sense we build upon one of the major stylized facts of modern growth structural change at all levels from the microeconomic to the macroeconomic to any observer of the policy making process let alone a practitioner the contrast between the theory which underpins policy and the implementation of policy will seem acute as nelson and winter i982 have rightly insisted research into policy is shaped by policy questions not by an agenda relating to how economic theory can be developed to deal with innovation setting priorities designing instruments and evaluating outcomes do not link easily with the general ideas dealt with below among the general points we will stress two will be of critical importance first that the innovation activities of firms involve a wider range of other institutions supplying the knowledge and skills which underpin the efforts of individual firms we term this the systems perspective on innovation nelson i993 secondly it is not helpful to treat innovation and the diffusion of innovation as separate categories in fact they are inseparable with feedback from diffusion being one of the critical elements shaping how a technology is developed we begin with a brief review of the familiar market failure perspective on policy and build from this into a brief overview of the evolutionary approach the paper concludes with an outline of the systems perspective on technology policy it is taken as read that virtually any economic policy can have implications in principle for the process of innovation however we treat technology policy in a narrow sense even though it spills over into questions of education policy science policy and competition policy

structural cycles and industrial policy alignment the private public nexus in the emilian packaging valley the article investigates changes in the interaction between business organisations local governments and public technology intermediaries resulting from business organisations shifts towards higher value product segment opportunities specifically we analyse how local governments can or not align their industrial policies to the industrial transformations both technological and organisational underpinning firms value creation capture dynamics the concept of structural cycle is introduced here to study the two interdependent processes of technology transition and organisational reconfiguration characterising those firms shifting towards higher value product segments this private public nexus is investigated in the emilian packaging valley context the mixed method study focuses on the case of ima spa its shifts from the food to the pharmaceutical value product segment of the packaging machine industry and its changing relationships with regional public policies and institutions a number of industrial policy implications for sustainable value creation dynamics in local production systems are finally derived

innovation policy rationales lessons and challenges innovation policy has emerged as a new field of economic policy during the last few decades this paper explores the rationales for national innovation policies as laid out in the existing literature on the subject and considers what the lessons and challenges for theory and practice in this area are innovation policy attempts to influence innovation activity often with the purpose of increasing economic growth but it can also have more specific aims such as preventing unwarranted climate change improving national health and so on the increasing attention given to innovation policy at the national level from the 1990s onwards went hand in hand with the development of a new systemic understanding of innovation which in a better way than before accounted for the stylised facts of innovation activity as identified by empirical work the system approach as the paper shows came to have a significant influence on the subsequent policy discourse drawing on recent advances in innovation systems theory a synthetic framework for the analysis of innovation policy is developed and used to highlight issues of particular relevance for the conduct of innovation policy and future scholarly work in this area less

estimating short and long term residential demand for electricity new evidence from sri lanka this study investigates the short run dynamics and long run equilibrium relationship between residential electricity demand and factors influencing demand per capita income price of electricity price of kerosene oil and price of liquefied petroleum gas using annual data for sri lanka for the period 1960 2007 the study uses unit root cointegration and error correction models the long run demand elasticities of income own price and price of kerosene oil substitute were estimated to be 0 78 0 62 and 0 14 respectively the short run elasticities for the same variables were estimated to be 032 0 16 and 0 10 respectively liquefied petroleum lp gas is a substitute for electricity only in the short run with an elasticity 0 09 the main findings of the paper support the following 1 increasing the price of electricity is not the most effective tool to reduce electricity consumption 2 existing subsidies on electricity consumption can be removed without reducing government revenue 3 the long run income elasticity of demand shows that any future increase in household incomes is likely to significantly increase the demand for electricity and 4 any power generation plans which consider only current per capita consumption and population growth should be revised taking into account the potential future income increases in order to avoid power shortages ill the country

evolutionary approaches for sustainable innovation policies from niche to paradigm fostering technological innovation is considered as an important element of policies towards sustainable development in the past 10 years evolutionary policy approaches have been increasingly advocated for several reasons they seem well equipped to underpin sustainable innovation policies they focus on dynamics of change and their drivers they allow for a substantive perspective on technologies beyond mere input output relations taking into account trajectories and different characteristics of innovation and they are able to describe circumstances under which established technologies might persist even when they are to some extent inferior to their new competitors lock in however the policy effectiveness of evolutionary approaches in cases in which radical or systemic changes are involved is not yet proven in this paper we assess the theoretical rationale instrumental aspects and the coping with policy constraints of three evolutionary policy approaches which have also been used in empirical studies strategic niche management transition management and time strategies each approach has its strengths and specific problems and all three have to be further developed and tested out but they hold promise for contributing to non incremental change with economic and environmental benefits by shaping processes of variation selection and retention with the outcomes feeding back into policy they may also be used in other areas in which innovation direction is important for instance health care or food

universities technology and innovation centres and regional development the case of the north east of england the paper examines the role of technology and innovation centres tics in bridging the gap between the university research base and industry in order to foster economic development in a lagging industrial region the context is provided by an academic literature on the role of universities in regional innovation systems some of which casts doubt on the capacity of universities to operate in this domain particularly within a lagging region the empirical case reports on a bold experiment initiated by the regional development agency in the older industrial region of the north east of england to create and support new tics in the fields of process innovation in high value manufacturing and new and renewable energy and on the engagement of a regionally committed university with these centres the evidence presented suggests that while there are links between the university and the centres both are principally operating in a national science and technology system in which contributing to addressing uneven regional economic development is a secondary concern copyright the author 2012 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

investigating a neglected part of schumpeter s creative army what drives new to the market innovation in micro enterprises schumpeterian arguments related to creative destruction place small entrepreneurial firms at the centre of the innovation process the exclusion of micro enterprises with less than 10 employees from most innovation surveys means however that we know relatively little about innovation among this group of firms here using new survey data on a thousand micro enterprises we explore the determinants of new to the market innovation the basis for the schumpeterian creative destruction cd process our results provide strong support for the interactive nature of micro enterprise innovation and suggest the potential value of a model of interactive creative destruction icd contrary to some other recent evidence market based and supplier based collaboration both prove important for new to the market innovation our results suggest the importance of micro enterprises as sources of new to the market innovation and the potential value of including such firms in future innovation studies
