monitoring changes in economy wide energy efficiency from energy gdp ratio to composite efficiency index since the 1973 world oil crisis monitoring trends in energy efficiency at the economy wide level has been an important component of energy strategy in many countries to support this effort various energy efficiency related indicators have been developed we examine some classical indicators which are often found in national and international energy studies in the 1970s and 1980s we then describe the recent developments in using the index decomposition analysis to give an economy wide composite energy efficiency index based on a bottom up approach this composite index is superior to the classical indicators as an economy wide energy efficiency measure and has lately been adopted by a growing number of countries for national energy efficiency trend monitoring

energy efficiency vs economic efficiency new zealand electricity sector reform in the context of the national energy policy objective abstract in this article i review the diverse commentaries on new zealand s ongoing electricity sector reform process within the context of the government s energy policy objective in doing so my purpose is to highlight the interactions between the concepts of energy efficiency and economic efficiency in particular i ask how do the various commentators on reform define these concepts what indicators do they use to measure them and what level of each do they prescribe as appropriate my main objective is not to decide whether any commentator is right or wrong rather i seek to identify the distinct world views or paradigms underlying the commentaries with respect to both energy efficiency and economic efficiency i conclude that economic efficiency is consistent with a supply side paradigm valuing economic growth whereas those who value energy efficiency over economic efficiency subscribe to a demand side paradigm recognising the limits to growth such a paradigm derives from the ethic of sustainability i close by posing the as yet unanswered question are these paradigms mutually exclusive

innovation in services the purpose of this article is to lay the foundations of a theory that can be used to interpret innovation processes in the service sector the hypothesis underpinning this article is based on lancaster s definition of the product in both manufacturing and services as a set of service characteristics the article follows the example of those who have sought to apply lancaster s work to technological phenomena various modes of innovation in the service sectors are highlighted and illustrated

energy conservation investment do consumers discount the future correctly we argue that the apparently high discount rates attributed to investors making energy conservation investments are not irrational or the result of some market failure rather they may result from an investor recognizing that many conservation investments entail substantial sunk costs in the presence of these costs and uncertainty over future conservation savings consumers should use a higher hurdle rate for investment than if there were no uncertainty simulations suggest that the hurdle rate should be about four times greater than the standard rate an implication of our model is that tax subsidies for the purchase of conservation capital are likely to be ineffective we discuss alternative policy approaches which are more likely to increase energy efficient investment namely mandatory efficiency standards and energy taxes

servitization in mergers and acquisitions manufacturing firms venturing from emerging markets into advanced economies abstract we investigate servitization by manufacturing firms that have ventured from emerging markets into advanced economies through mergers and acquisitions m a the study seeks to answer two questions a what is the relationship between m as and servitization in the case of manufacturing firms and b what are the factors influencing the configuration of servitization strategies and their implementation the study provides a nuanced and contextualized understanding of servitization in m as existing research on servitization has paid insufficient attention to collaborative partnerships there is a need to examine the role of servitization in the context of collaborative partnerships our empirical setting consists of chinese manufacturing firms acquisitions in germany using qualitative research methods we reveal a typology of servitization strategies adding utilizing and reconfiguring that underpin the combined influences of different levels of services of both acquirer and target firms in the m a we identify integration mode and absorptive capacity as factors influencing service capability development our findings contribute to the literature on alternative approaches to servitization by firms from emerging markets venturing into advanced economies we discuss the theoretical and managerial implications and suggest future research directions for servitization in collaborative partnerships in general and in m a in particular

development of the wind power in brazil political social and technical issues abstract this paper aims to present a review of the increasing contribution of wind power to the brazilian electric matrix and an analysis of the main impact on technical political and social aspects this work takes into account the state of art of the wind power technology the wind resource potential and the evolution of installed capacity in the country the institutional programs and the fiscal incentives provided by the brazilian government are also discussed in this paper including its impacts on the society we have reviewed national and international reports and relevant scientific papers to realize this work the analysis shows that electric crisis in 2001 led the brazilian government to develop new energy policies that supported the rapid growth of the wind industry from imported technology later on in the year 2004 the government mandated that the technology be developed within the country it is expected that from 2011 of approximately 1500 mw until 2021 the installed wind capacity would increase by a factor of 600 however the national technology acquisition and development is still incipient it is important to produce locally wind turbine components and is highly desirable to increase collaboration between industries and universities in the country

customer satisfaction productivity and profitability differences between goods and services there is widespread belief that firms should pursue superiority in both customer satisfaction and productivity however there is reason to believe these two goals are not always compatible if a firm improves productivity by downsizing it may achieve an increase in productivity in the short term but future profitability may be threatened if customer satisfaction is highly dependent on the efforts of personnel if so there are potential tradeoffs between customer satisfaction and productivity for industries as diverse as airlines banking education hotels and restaurants managers in these types of service industries as well as goods industries in which the service component is increasing need to understand whether or not this is the case for example if efforts to improve productivity can actually harm customer satisfaction and vice versa the downsizing of u s and european companies should be viewed with concern it follows that developing a better understanding of how customer satisfaction and productivity relate to one another is of substantial and growing importance especially in light of expected continued growth in services throughout the world economy the objective of this paper is to investigate whether there are conditions under which there are tradeoffs between customer satisfaction and productivity a review of the literature reveals two conflicting viewpoints one school of thought argues that customer satisfaction and productivity are compatible as improvements in customer satisfaction can decrease the time andeffort devoted to handling returns rework warranties and complaint management while at the same time lowering the cost of making future transactions the second argues that increasing customer satisfaction should increase costs as doing so often requires efforts to improve product attributes or overall product design a conceptual framework useful in resolving these contradictory viewpoints is developed the framework serves in turn as a basis for developing a theoretical model relating customer satisfaction and productivity the model predicts that customer satisfaction and productivity are less likely to be compatible when 1 customer satisfaction is relatively more dependent on customization the degree to which the firm s offering is customized to meet heterogeneous customers needs as opposed to standardization the degree to which the firm s offering is reliable standardized and free from deficiencies and 2 when it is difficult costly to provide high levels of both customization and standardization simultaneously to move forward from the model s propositions to the development of testable hypotheses we argue that services are more likely than goods to have the preceding characteristics hence tradeoffs between customer satisfaction and productivity should be more prevalent for services than for goods although this classification is not precise many services are standardizable and many goods have a service component it has the advantage of allowing an initial test of the propositions the empirical work employs a database matching customer based measures of firm performance with traditional measures of business performance such as productivity and return on investment roi the central feature of this database is the set of customer satisfaction indices provided by the swedish customer satisfaction barometer scsb the scsb provides a uniform set of comparable customer based firm performance measures and offers a unique opportunity to test the study s hypotheses the findings indicate that the association between changes in customer satisfaction and changes in productivity is positive for goods but negative for services in addition while both customer satisfaction and productivity are positively associated with roi for goods and services the interaction between the two is positive for goods but significantly less so for services taken together the findings suggest support for the contention that tradeoffs are more likely for services hence simultaneous attempts to increase both customer satisfaction and productivity are likely to be more challenging in such industries of course this does not imply that such firms should not seek improvements in both productivity and customer satisfaction for example appropriate applications of information technology may improve both customer satisfaction and productivity simultaneously the findings should provide motivation for future research concerning the nature of customer satisfaction and productivity as well as appropriate strategy and tactics for each one it is worth emphasizing that this is an issue that is not only important today but certainly will become even more important in the future as the growth of services continues and world markets become increasingly competitive the importance of customer satisfaction will also increase to compete in such a world firms must strike the right balance between their efforts to compete efficiently and their efforts to compete effectively

economies of scale and economies of scope in multiproduct financial institutions a study of british columbia credit unions this paper investigates the production technology facing computerized credit unions in canada a full system of translog cost equations is estimated in order to test for economies of scale economies of scope and other production characteristics in a multiproduct context the regression results indicate that most of the credit unions in our sample experience significant increasing returns to scale as they expand their level of output there is also evidence of cost complementarity or economies of scope in their mortgage and other lending activities as a result legislation which limits the ability of credit unions to grow and diversify will likely raise the operating costs of this important group of financial institutions additional structural tests of the most general translog specification suggest that none of the restrictive production conditions commonly imposed by other researchers using cobb douglas and ces specifications provide a valid representation of credit union technology the results of many earlier studies are therefore open to question this paper presents a number of structural tests of the production technology facing large computerized credit unions in canada a full system of translog cost equations is estimated using detailed cross sectional data on british columbia credit unions the parameter estimates obtained from our multiproduct specification allow us to test for economies of scale economies of scope and factor substitution unlike many earlier studies the present paper introduces the various outputs as separate variables instead of crudely proxying them with a single output measure such as total assets the total number of loans or the number of depositors by explicitly recognizing the multiproduct nature of the intermediation process we are able to address more interesting production questions and remove some of the bias caused by misspecification and measurement error in simpler approaches the flexible translog specification allows us to estimate the sensitivity of costs to proportionate increases in all outputs economies of scale as well as the cost savings firms realize by producing several outputs jointly rather than specializing in the production of one economies of scope the test results reported in the latter part of the paper suggest that increasing returns to scale exist in almost all of the credit unions in our sample though

demand side management overcoming market barriers or obscuring real costs abstract this paper compares two approaches to estimating the net benefits of a demand side management program that subsidizes the purchase of efficient equipment the total resource cost trc test suggests net benefits of us 6 9 million estimates based on consumer s surplus yield an estimated net loss of us 6 3 million this gap is due to differences in estimates of participants net benefits market failures do not appear to be significant and thus cannot explain much of the gap the more plausible explanation is that the trc uses a lower discount rate than participants use for themselves and it omits some costs

markets for energy efficiency exploring the implications of an eu wide tradable white certificate scheme recent developments in european energy policy reveal an increasing interest in implementing the so called tradable white certificate twc schemes to improve energy efficiency based on three evaluation criteria cost effectiveness environmental effectiveness and distributional equity this paper analyses the implications of implementing a european wide twc scheme targeting the household and commercial sectors using a bottom up model quantitative results show significant cost effective potentials for improvements ca 1400 twh in cumulative energy savings by 2020 with the household sector gas and space heating representing most of the twc supply in terms of eligible sector fuel and energy service demand respectively if a single market price of negative externalities is considered a societal costeffective potential of energy savings above 30 compared to the baseline is observed in environmental terms the resulting greenhouse gas emission reductions are around 200mt co2 eq by 2010 representing nearly 60 of the eu kyoto target from the qualitative perspective several embedded ancillary benefits are identified e g employment generation improved comfort level reduced fuel poverty security of energy supply whereas an eu wide twc increases liquidity and reduces the risks ofmarket power autarky compliance strategies may be expected in order to capture co benefits nationally cross subsidies could occur due to investment recovery mechanisms and there is a risk that effects may be regressive for low income households assumptions undertaken by the modelling approach strongly indicate that high effectiveness of other policy instruments is needed for an eu wide twc scheme to be cost effective less

us residential energy demand and energy efficiency a stochastic demand frontier approach this paper estimates a us frontier residential aggregate energy demand function using panel data for 48 states over the period 1995 to 2007 using stochastic frontier analysis sfa utilizing an econometric energy demand model the in efficiency of each state is modeled and it is argued that this represents a measure of the inefficient use of residential energy in each state i e waste energy this underlying efficiency for the us is therefore observed for each state as well as the relative efficiency across the states moreover the analysis suggests that energy intensity is not necessarily a good indicator of energy efficiency whereas by controlling for a range of economic and other factors the measure of energy efficiency obtained via this approach is this is a novel approach to model residential energy demand and efficiency and it is arguably particularly relevant given current us energy policy discussions related to energy efficiency

the persistence of profits a european comparison this paper is concerned with modeling the movements in profits of firms over time at the heart of the emp irical model is a latent variables problem which arises from the fact that entry and imitation do not actually have to occur to have an ef fect on profits a solution to this problem is explored and then emp irical results are presented comparing a sample of firms from the uni ted kingdom france and west germany copyright 1988 by royal economic society

economies of scale in services a study of multinational insurers this study investigates whether multinational insurers achieve economies of scale using a time series cross sectional design it analyzes the relationship between expenses and output of multinational insurers the study finds that multinational insurers achieve economies of scale only up to a point and rather than benefitting from scale the most internationally diverse insurers suffer diseconomies the conclusion is that the benefits of extensive foreign acquisitions by insurers are questionable

measuring market power in the ready to eat cereal industry the ready to eat cereal industry is characterized by high concentration high price cost margins large advertising to sales ratios and numerous introductions of new products previous researchers have concluded that the ready to eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense nonprice competition this paper empirically examines this conclusion in particular i estimate price cost margins but more importantly i am able empirically to separate these margins into three sources i that which is due to product differentiation ii that which is due to multi product firm pricing and iii that due to potential price collusion the results suggest that given the demand for different brands of cereal the first two effects explain most of the observed price cost margins i conclude that prices in the industry are consistent with noncollusive pricing behavior despite the high price cost margins leading firms are able to maintain a portfolio of differentiated products and influence the perceived product quality it is these two factors that lead to high price cost margins

barriers within firms to energy efficient investments abstract many investments in energy efficiency fail to be made despite their apparent profitability internal hurdle rates are often set at levels higher than the cost of capital to the firm reasons for these practices include bounded rationality principal agent problems and moral hazard the policy implication is that government can simultaneously improve overall energy efficiency and increase private sector productivity by providing informational and organizational services that go beyond the traditional regulatory framework

been top down so long it looks like bottom up to me abstract while technologists emphasize suboptimal choices by individuals and organizations many economists have ignored behavior exhibiting technical inefficiency this paper selectively discusses efforts by some economists to identify and measure technical inefficiency as applied to the energy efficiency gap bottom up economics would seek to measure significant departures from best practice technology distinguish between inefficiency that is more less wasteful of energy than other inputs and focus on developing testable hypotheses about technical inefficiency support for widespread intervention in energy use decisions may not necessarily follow from such an inquiry

dynamic capabilities what are they this paper focuses on dynamic capabilities and more generally the resource based view of the firm we argue that dynamic capabilities are a set of specific and identifiable processes such as product development strategic decision making and alliancing they are neither vague nor tautological although dynamic capabilities are idiosyncratic in their details and path dependent in their emergence they have significant commonalities across firms popularly termed best practice this suggests that they are more homogeneous fungible equifinal and substitutable than is usually assumed in moderately dynamic markets dynamic capabilities resemble the traditional conception of routines they are detailed analytic stable processes with predictable outcomes in contrast in high velocity markets they are simple highly experiential and fragile processes with unpredictable outcomes finally well known learning mechanisms guide the evolution of dynamic capabilities in moderately dynamic markets the evolutionary emphasis is on variation in high velocity markets it is on selection at the level of rbv we conclude that traditional rbv misidentifies the locus of long term competitive advantage in dynamic markets overemphasizes the strategic logic of leverage and reaches a boundary condition in high velocity markets copyright 2000 john wiley sons ltd

estimating bounds on the economy wide effects of the cef policy scenarios abstract the scenarios for a clean energy future study relied primarily on bottom up technology based methods to estimate costs associated with its scenarios these methods however do not allow for calculation of economy wide or general equilibrium effects of the policies considered we propose and apply a means of combining the bottom up estimates with estimates of the costs associated with a carbon charge obtained from computable general equilibrium models our approach is based on the concept of production inefficiency the economy lies within its production frontier with respect to the provision of energy services the cef technology policies are interpreted as moving the economy toward its frontier as well as moving the frontier outward while the carbon charge induces a substitution effect along the frontier this perspective allows a synthesis of the two sets of calculations

measurement of energy efficiency based on economic foundations abstract energy efficiency policy is seen as a very important activity by almost all policy makers in practical energy policy analysis the typical indicator used as a proxy for energy efficiency is energy intensity however this simple indicator is not necessarily an accurate measure given changes in energy intensity are a function of changes in several factors as well as true energy efficiency hence it is difficult to make conclusions for energy policy based upon simple energy intensity measures related to this some published academic papers over the last few years have attempted to use empirical methods to measure the efficient use of energy based on the economic theory of production however these studies do not generally provide a systematic discussion of the theoretical basis nor the possible parametric empirical approaches that are available for estimating the level of energy efficiency the objective of this paper therefore is to sketch out and explain from an economic perspective the theoretical framework as well as the empirical methods for measuring the level of energy efficiency additionally in the second part of the paper some of the empirical studies that have attempted to measure energy efficiency using such an economics approach are summarized and discussed

trade imbalance in international message telephone services an econometric model is estimated to identify determinants of trade imbalance in international message telephone services markets results indicate that asymmetric market structure is important in explaining bilateral market imbalances for high income country pairs for low and high income country pairs gdp per capita is the dominant cause of traffic imbalances the findings suggest that telecommunications liberalization policies are effective in reducing distortions in international traffic flows and settlement payments however liberalization should be accompanied by developmental programmes that enhance income per capita and telecommunications network investment in developing countries such programmes may be effective in providing a more equitable distribution of the gains from telecommunications reform across countries

can neoclassical economics underpin the reform of centrally planned economies te here s a curious symmetry between the arguments propounded over the last century in advocacy of socialism and the present popular discussion of the reform of centrally planned economies in those old discussions the vision of socialism was utopian which was contrasted with the dickensian realities of capitalism now the disasters of central planning are contrasted with the benefits flowing from perfectly functioning markets in the conventional wisdom of reform the vision of markets is utopian and that of central planning concentrates on the awful reality what is largely missing in the conventional wisdom is a satisfactory attempt to come to grips with the central question that should be answered in formulating reform plans how does one explain the differences in performance of market capitalist and centrally planned economies of course capitalism has outperformed central planning the developed west is therefore an obvious source of ideas for reforms but the institutions of capitalism come in many varieties and cannot be put in place instantaneously there are many alternative reform paths depending upon the importance attributed to each of these institutions thus there remains the problem of tracing the source of the superiority of capitalist economies to specific characteristics this point was made clear to me on hearing a vietnamese official justify single party rule by noting the economic success of taiwan and singapore reformers need a filter that interprets the experience of capitalist and socialist systems this is exactly where economic theory plays a vital role

do markets differ much this essay reports the results of a crosssection study of differences in accounting profitability that sheds light on some basic controversies in industrial economics most previous cross section studies in this field have been concerned with testing hypotheses about structural coefficients in models meant to apply to essentially all markets as we have learned more about the difficulties of constructing such general models and of performing tests on their structural parameters properly structural cross section analysis has fallen out of fashion in contrast to most of the cross section literature the analysis reported here is fundamentally descriptive it does not attempt directly to estimate or to test hypotheses about structural parameters i hope to show by example that one can perform illuminating analysis of cross section data without a host of controversial maintained hypotheses cross section data can yield interesting stylized facts to guide both general theorizing and empirical analysis of specific industries even if they cannot easily support full blown structural estimation one can view the sort of search for stylized facts conducted here as either a replacement for or an input to interindustry structural estimation depending on one s feeling about the long run potential of that research approach this study also departs from much of the cross section literature by being fundamentally concerned with the importance of various effects not just with coefficient signs and t statistics in particular this essay provides estimates of the relative importance of firm market and market share differences in the determination of business unit divisional profitability in u s manufacturing using 1975 data from the line of business program of the u s federal trade commission ftc i find support neither for the existence of firm effects nor for the importance of market share effects moreover while industry effects apparently exist and are important they appear to be negatively correlated with seller concentration in these data section i relates firm market and share effects to current issues and controversies in industrial economics and thus supplies the motivation for our empirical analysis the remainder of the essay treats the data and

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

diffusion of renewable heating technologies in households experiences from the norwegian household subsidy programme abstract a sample of 896 norwegian households participating in a subsidy programme was surveyed in order to evaluate the success of the programme the programme subsidised investments in new heating technologies including heat pumps and pellet stoves the success of the programme was measured by the degree of overall satisfaction with the investment by the sampled households theories on diffusion of innovations and planned behaviour motivate the empirical modelling of the investment satisfaction the economic return on the investment varied substantially both within and between the two heating technologies with heat pumps outperforming pellet stoves in this respect still the economic return showed no explanatory power toward the investment satisfaction of the household among the economic variables only the electricity price had any influence on investment satisfaction technical quality indoor climate and heat comfort and the availability of the supplier of the heating equipment were the most important explanatory variables

does uniqueness in banking matter abstract we investigate whether and how the uniqueness of banking activities affects the performance and systemic risk of u s banks we find that banks performing more unique activities exhibit higher profitability and lower risk controlling for size diversification and other key characteristics we further find that banks sensitivity to systemic risk displays an inversely u shaped relation with activity uniqueness we interpret the impact of uniqueness in analogy to recent theories showing that systemic diversity promotes financial stability our study highlights the role of uniqueness in banking and has important implications for policy makers and banking regulators

services and the business models of product firms an empirical analysis of the software industry some product firms increasingly rely on service revenues as part of their business models one possible explanation is that they turn to services to generate additional profits when their product industries mature and product revenues and profits decline we explore this assumption by examining the role of services in the financial performance of firms in the prepackaged software products industry standard industrial classification code 7372 from 1990 to 2006 we find a convex nonlinear relationship between a product firm s fraction of total sales coming from services and its overall operating margins as expected firms with a very high level of product sales are most profitable and rising services are associated with declining profitability we find however that additional services start to have a positive marginal effect on the firm s overall profits when services reach a majority of a product firm s sales we show that traditional industry maturity arguments cannot fully explain our data it is likely that changes in both strategy and the business environment lead product firms to place more emphasis on services this paper was accepted by christoph loch r d and product development

risk aversion and willingness to pay for energy efficient systems in rental apartments abstract this paper uses a random utility model to estimate consumers valuation of energy efficient insulation and ventilation systems in rental apartments given consumers limited experience in residential buildings and the perceived uncertainty about their comfort benefits and resulting energy savings these relatively new technologies might be undervalued by risk averse consumers using the concept of certainty equivalence this paper proposes a model to assess the consumers risk aversion for adopting energy efficient systems these systems are treated as risky assets while conventional commodities are assumed to be risk free the curvature of the utility function is interpreted as a measure of aversion to perceived risks as opposed to explicit risks measured by observed variances the proposed formulation is applicable in stated preference data with qualitative variables the model is applied to data from a choice experiment conducted among 264 apartment tenants in switzerland the estimated curvatures reject the risk neutrality hypothesis the range of the estimated risk premiums suggests that risk considerations remain a central issue in dealing with energy efficiency in residential buildings the analysis also indicates that assuming same risk attitudes toward new and conventional systems could bias the estimates of the willingness to pay especially when the system is comprised of several components

when is servitization a profitable competitive strategy abstract although servitization has emerged as a new competitive strategy for manufacturers there has been little research about product level servitization we investigate the competition between two channels one separately providing both goods and services and the other providing inseparable servitized goods through a game theoretic approach two critical parameters to understand competition between the two channels will be proposed 1 service dependency a degree of dependency of physical goods upon services and 2 channel substitutability a degree of substitution between conventional channels and servitized one the study reveals that the servitization strategy is a better choice for a manufacturer selling physical goods only when the goods require a higher level of service i e high service dependency and when the competition between the two channels is more severe i e high channel substitutability in addition obtaining cost efficiency is found to be an important factor to achieve higher competitive advantage over the other channel
