price discrimination in broadway theater a common thread in the theory literature on price discrimination has been the ambiguous welfare effects for consumers and the rise in profit for firms relative to uniform pricing in this study i resolve the ambiguity for consumers and quantify the benefit for a firm i describe a model of price discrimination that includes both second degree and third degree price discrimination using data from a broadway play i estimate the structural model and conduct various experiments to investigate the implications of alternative pricing policies the observed price discrimination may improve the firm s profit by approximately 5 relative to uniform pricing while the difference for aggregate consumer welfare is negligible also i show that the gain from changing prices in the face of fluctuating demand is small under the observed price discrimination

nonlinear pricing in an oligopoly market the case of specialty coffee firms that use nonlinear pricing may distort product characteristics away from their efficient levels this paper offers the first empirical study of this issue using data from a specialty coffee market i estimate a structural utility model to compute consumers benefits from changing products sizes i then compare the estimated benefits to cost data design distortions are relatively large for products not targeted to the highest demand consumers distortions decrease toward zero with drink size for products with the largest profit margins these results support some of the central predictions from nonlinear pricing theory including no distortion at the top

inflation uncertainty and growth in a cash in advance economy abstract this paper analyzes the effects of inflation variability on economic growth in a model where money is introduced via a cash in advance constraint in this setting we find that inflation adversely affects long run growth even when the cash in advance constraint applies only to consumption at the same time we find that inflation and growth are positively related in the short run furthermore variability increases average growth through a precautionary savings motive since inflation and inflation variability tend to be highly correlated the presence of uncertainty attenuates the negative long run relationship between inflation and real growth it also provides a partial rationale for the apparent lack of robustness in cross country regressions of growth and inflation

price discrimination copyright law and technological innovation evidence from the introduction of dvds u s copyright law effectively prevents direct price discrimination for copyright holders that sell to different markets in response these firms can engage in indirect price discrimination i derive theoretical predictions about the use of indirect price discrimination and i analyze how optimal pricing strategies differ for different products using data on vhs and dvd movie distribution i find that firms pricing choices are consistent with the predictions of theory and that firms use of indirect price discrimination benefits consumers but harms ancillary retailers finally i examine what optimal pricing strategies might look like in a legal environment that permits direct price discrimination

inflation output growth and nominal and real uncertainty empirical evidence for the g7 abstract we use univariate garch models of inflation and output growth and monthly data for the g7 covering the 1957 2000 period to test for the causal effect of real and nominal macroeconomic uncertainty on inflation and output growth and the effect of inflation on inflation uncertainty our evidence supports a number of important conclusions first inflation is a positive determinant of uncertainty about inflation second output growth uncertainty is a positive determinant of the output growth rate third there is mixed evidence regarding the effect of inflation uncertainty on inflation and output growth hence uncertainty about the inflation rate is not necessarily detrimental to economic growth finally there is not much evidence supporting the hypothesis that output uncertainty raises inflation

inflation and asset returns in a monetary economy postwar u s data are characterized by negative correlations between real equity returns and inflation and by positive correlations between real equity returns and money growth these patterns are closely matched quantitatively by an equilibrium monetary asset pricing model the model also implies negative correlations between expected asset returns and expected inflation and it predicts that the inflationasset return correlation will be more strongly negative when inflation is generated by fluctuations in real economic activity than when it is generated by monetary fluctuations the co movements of real asset returns inflation and money growth have been studied extensively over the past fifteen years table i displays some of the statistical properties of these series using quarterly u s data from 1959 to 1990 note first the significantly negative correlation between real equity returns and inflation note also the negative correlation between inflation and the ex post real return to nominally riskless bonds while this fact is not particularly surprising numerous studies conclude that the correlations between ex ante real asset returns and expected inflation are also negative 2 in contrast to these patterns the correlation between money growth and real equity returns is weakly positive in the data while the correlation between money growth and the real bond return is virtually zero initially these empirical patterns were viewed as anomalies negative correlations between inflation and ex post real stock returns contradict the traditional view that equities ought to act as an inflation hedge 3 negative correlations between expected inflation and ex ante real returns violate the

difficulty is critical the importance of social factors in modeling diffusion of green products and practices abstract despite the very positive as measured by market surveys attitude towards eco innovations and sustainability in general the actual market penetration of green products and practices generally falls behind the expectations in this paper we argue that considering difficulty of engagement as used in the campbell paradigm is of critical importance when modeling diffusion of eco innovations such a notion of difficulty possesses three desired properties i parsimony it is represented by a single value ii interpretability it can be regarded as an estimator of the otherwise complex notion of behavioral cost and iii applicability it can be easily measured through market surveys in an extensive simulation and analytical study involving empirically measured difficulty and an agent based model spanned on different social network structures we show that innovation adoption may exhibit abrupt changes in market penetration as a result of even small changes in difficulty the latter may be of particular interest to policy makers who have to make strategic decisions when introducing socially but not necessarily individually desired products and practices like dynamic or green electricity tariffs

vertical contracts in the video rental industry a large body of theoretical work has explored the channels through which vertical contracts can induce efficiency improvements however it is also important to study vertical contracts empirically in order to gain insight into the relative size of different types of efficiency gains in this paper i empirically analyse a contractual innovation in the vertically separated video rental industry prior to 1998 video stores obtained inventory from movie distributors using simple linear pricing contracts in 1998 revenuesharing contracts were widely adopted i investigate the effect of the introduction of revenue sharing contracts on firms profits and consumer welfare i analyse a new panel data set of home video retailers that includes information on individual retailers contract and inventory choices as well as rentals and contract terms for 246 movie titles and 6137 retailers in the u s during each week of 1998 and 1999 and the first half of 2000 a structural econometric model of firms behaviour is developed that describes the nature of firms contract choices estimates from this model indicate that both upstream and downstream profits increase by 10 under the revenue sharing contract for popular titles for less popular titles the effects can be even larger i also estimate that consumers benefit when revenue sharing contracts are adopted

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

fiscal deficits and inflation abstract macroeconomic theory postulates that persistent fiscal deficits are inflationary yet empirical research has had limited success in uncovering this relationship this paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory unlike previous studies we model inflation as non linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic using panel techniques that explicitly distinguish between short and long run effects of fiscal deficits results spanning 107 countries over 1960 2001 show a strong positive association between deficits and inflation among high inflation and developing country groups but not among low inflation advanced economies

stock returns and inflation with supply and demand disturbances we account for the relation between stock returns and inflation with two independent disturbances supply shocks and demand shocks supply shocks reflect real output shocks and cause a negative relation between stock returns and inflation while demand shocks are mainly due to monetary shocks and generate a positive relation between stock returns and inflation we show both theoretically and empirically that the stock return inflation relation varies over time and across countries depending on the relative importance of the two types of shocks our empirical evidence is based on pre and postwar periods in the united states as well as the postwar period in the united kingdom japan germany article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

financial development financial fragility and growth the authors study the apparent contradiction between two strands of the literature on the effects of financial intermediation on economic activity on the one hand the empirical growth literature finds a positive effect of financial depth as measured by for instance private domestic credit and liquid liabilities for example levine loayza and beck 2000 on the other hand the banking and currency crisis literature finds that monetary aggregates such as domestic credit are among the best predictors of crises and their related economic downturns for example kaminski and reinhart 1999 the authors account for these contrasting effects based on the distinction between the short and long run impacts of financial intermediation working with a panel of cross country and time series observations they estimate an encompassing model of short and long run effects using the pooled mean group estimator developed by pesaran shin and smith 1999 their conclusion from this analysis is that a positive long run relationship between financial intermediation and output growth coexists with a mostly negative short run relationship the authors further develop an explanation for these contrasting effects by relating them to recent theoretical models by linking the estimated short run effects to measures of financial fragility namely banking crises and financial volatility and by jointly analyzing the effects of financial depth and fragility in classic panel growth regressions

community perspectives of wind energy in australia the application of a justice and community fairness framework to increase social acceptance decisions concerning the siting of infrastructure developments or the use of natural resources have the potential to damage a community s social well being if the outcomes are perceived to be unfair justice is accepted as central to the well functioning of society with fairness being an expectation in day to day interactions outcomes that are perceived to be unfair can result in protests damaged relationships and divided communities particularly when decisions are made which benefit some sections of the community at the perceived expense of others through empirical research using a wind farm pilot study community perceptions of a community consultation process are explored using procedural justice principles to evaluate fairness findings from the pilot study indicate that perceptions of fairness do influence how people perceive the legitimacy of the outcome and that a fairer process will increase acceptance of the outcome a key research finding was that different sections of a community are likely to be influenced by different aspects of justice namely by outcome fairness outcome favourability and process fairness based on this finding a community fairness framework was developed which has potential application in community consultation to increase social acceptance of the outcome

foreign direct investment and intellectual property rights evidence from hollywood s global distribution of movies and videos abstract traditional thinking about intellectual property rights ipr suggests that as a country strengthens its ipr standards firms will move their governance structures away from equity based institutions such as foreign direct investment fdi towards more market based relations such as licensing agreements this hypothesis is explored by examining the behavior of hollywood studios in both the feature film and video markets in 40 foreign countries the analysis reveals that the behavior of hollywood studios is more complex than this although moderate iprs are associated with a high degree of licensing both high and low standards of ipr encourage more integrated governance structures

the intertemporal consequences of unauthorized reproduction of intellectual property in an intertemporal framework the harm to firms from unauthorized reproduction of their products may be significantly greater than that predicted by most static models copying by some consumers reduces the appropriable surplus from all consumers including those consumers lacking any propensity to copy somewhat paradoxically however the commitment value of copies may also imply that profits are higher with copying than without copying it is therefore suggested that firms may prefer differential copyright enforcement and that the commitment value of copies may offer a strategic explanation for free giveaways of abridged versions of intellectual property and vertical product differentiation more generally

analysis of the effectiveness of national renewable energy policies a case of photovoltaic policies abstract although fossil fuels are the main sources of power generation they are losing their advantages because of their limitations and environmental and economic concerns as an alternative the development of renewable energy technologies is one of the important strategies therefore governments have been encouraging the deployment of renewable energy resources however there are gaps between achievements and targets as most of the national renewable energy development policies are formulated in the entire country equally the outputs and achievements are different depending on the geographical characteristics social and economic capabilities of the regions the purpose of the present study is the analysis and the evaluation of the effectiveness of the equal national renewable energy policy in the different regions of a country this research focuses on the idea that whether the codification of energy policies according to the local circumstances of each region can result in a greater efficiency of such policies an innovative framework is presented to categorize the government policies based on the geographical technical and socio economic indicators to examine the presented framework it is implemented as a case study

selling costs and switching costs explaining retail gasoline margins recent theoretical work has shown that price discrimination can take place in imperfectly competitive as well as monopoly markets the persistence of higher retail margins on unleaded than on leaded gasoline during the 1980s suggests that discrimination may occur even in very competitive markets this article studies a number of cost based explanations for such gasoline pricing as well as the possibility of price discrimination the analysis indicates that gas stations discriminate against groups of customers who are less likely to switch to another station the conclusions highlight the influence of shopping or search costs on pricing decisions even in markets thought to be quite competitive

monopoly with incomplete information recent theoretical research on principal agent relationships has emphasized incentive problems that arise when the parties involved are constrained by either asymmetric information or their inability to monitor each other s actions here we concentrate on the former constraint and consider the case of a single principal the monopolist the main contribution is to show that under a separability assumption strong conclusions can be drawn about the nature of optimal incentive schemes although the primary focus is on optimal quantity discounts in a monopolized market the results also shed light on related topics such as optimal income taxation and commodity bundling

the relation between stock prices and inflationary expectations the international evidence this paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971 80 the fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world using interest rates as a proxy for expected inflation our data provide consistent support for the geske and roll model whose basic hypothesis is that stock price movements signal negative revisions in inflationary expectations finally a weak real interest rate effect was found for some of these countries

the stock return inflation puzzle and the asymmetric causality in stock returns inflation and real activity abstract in this paper we use a modified concept of granger non causality in reconsidering the negative correlation between stock returns and inflation known in the literature as stock return inflation puzzle based on the quarterly data for germany including stock returns inflation rates and growth rates of gross domestic production it turns out that the proxy causality between stock returns and inflation may be regarded as an asymmetric one and the indicative role of stock returns may be also asymmetrically granger causal to the growth rates of gross domestic production

inflation uncertainty and interest rates is the fisher relation universal this paper tests the validity of the fisher hypothesis which establishes a positive relation between interest rates and expected inflation for the g7 countries and 45 developing economies for this purpose we estimate a version of the garch specification of the hypothesis for all countries included in the sample we also test the augmented fisher relation by including the inflation uncertainty in the equation the simple fisher relation holds in all g7 countries but in only 23 developing countries there is a positive and statistically significant relationship between interest rates and inflation uncertainty for six of the g7 and 18 of the developing countries and this relationship is negative for seven developing countries

social acceptance of renewable energy innovation an introduction to the concept this paper introduces the special issue on social acceptance of renewable energy innovation it is a collection of best papers presented at an international research conference held in tramelan switzerland in february 2006 while there are ambitious government targets to increase the share of renewable energy in many countries it is increasingly recognized that social acceptance may be a constraining factor in achieving this target this is particularly apparent in the case of wind energy which has become a subject of contested debates in several countries largely due to its visual impact on landscapes this paper introduces three dimensions of social acceptance namely socio political community and market acceptance factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects the third dimension market acceptance has received less attention so far and provides opportunities for further research particularly from management scholars

monetary regimes and the relation between stock returns and inflationary expectations this paper analyzes the impact of changes in monetary policy regimes on the relation between stock returns and changes in expected inflation post war evidence from four countries reveals a direct link between these relations and the central banks operating targets i e money supply or interest rates specifically the post war negative relations between stock returns and changes in expected inflation are significantly stronger during interest rate regimes

inflation and real stock returns revisited i introduction this article empirically reinvestigates the relationship between real stock returns and inflation according to fisher 1930 1 in an efficient market real stock returns should reflect expectations only about real factors such as growth in output and time preference of savers such that real stock returns and inflation should vary independently in other words on average investors are fully compensated for erosions in purchasing power over time however this so called generalized fisher hypothesis has received little empirical support while kaul 1990 boudoukh and richardson 1993 solnik and solnik 1997 madsen 2005 and ryan 2006 find positive or weakly positive correlation between stock returns and inflation most empirical studies including nelson 1976 fama 1981 1983 geske and roll 1983 gultekin 1983 kaul 1987 and solnik 1983 uncover a negative effect of inflation anticipated and or unanticipated on real or nominal stock returns these apparent inconsistencies between the data and the predictions of economic theory have been termed as the stock return inflation puzzle and cited as evidence of monetary nonsuperneutrality or irrationality and market inefficiency 2 to reconcile the seemingly conflicting contributions danthine and donaldson 1986 provide a rational expectations equilibrium model in which a negative relation between stock returns and inflation arises from non monetary sources e g a real output shock and a positive relation is driven by purely monetary sources stulz 1986 marshall 1992 and bakshi and chen 1996 also assert that stock returns may be negatively correlated with inflation especially when the source of inflation is related to nonmonetary factors evidently hess and lee 1999 khil and lee 2000 and lee 2003 find that while monetary shocks drive a positive correlation real fiscal or real output shocks result in a negative correlation between stock returns and inflation from a different perspective kaul 1987 1990 argues that the relation between these two variables depends on both the money demand and the money supply specifically while the combination of money demand effects with a countercyclical monetary response accentuates a negative correlation money demand shocks along with a procyclical monetary response lead to a neutral or positive correlation between real stock returns and inflation similar arguments can be found in day 1984 kaul and seyhun 1990 boudoukh richardson and whitelaw 1994 and gallagher and taylor 2002 and are supported by compelling empirical evidence see e g kim 2003 lee 1992 as an alternative this article models the real stock return inflation relationship as intrinsically dynamic explicitly distinguishing between the short run and the long run such a distinction is crucial because imperfect information rigidity and or contractual obligations are more prevalent in the short run than in the long run in that sense the response of real stock returns to inflation could differ in the short run versus long run moreover we assess the long and short run impacts of inflation uncertainty on real stock returns as argued the real costs of inflation are associated with its uncertainty greater inflation uncertainty resulting from higher inflation may lead to economic inefficiency lower real investment and unemployment thereby reducing economic growth thus it is interesting to see if there are independent effects of inflation uncertainty on real stock returns both in the short run and in the long run in so doing this article uses an innovative econometric technique to explore the long and short run relationships between real stock returns and inflation both anticipated and unanticipated and the relationships with inflation uncertainty it departs from earlier work and complements recent evidence in at least three aspects

public attitudes regarding large scale solar energy development in the u s abstract using data collected from both a national sample as well as an oversample in u s southwest we examine public attitudes toward the construction of utility scale solar facilities in the u s as well as development in one s own county our multivariate analyses assess demographic and socio psychological factors as well as context in terms of proximity of proposed project by considering the effect of predictors for respondents living in the southwest versus those from a national sample we find that the predictors and impact of the predictors related to support and opposition to solar development vary in terms of psychological and physical distance overall for respondents living in the u s southwest we find that environmentalism belief that developers receive too many incentives and trust in project developers to be significantly related to support and opposition to solar development in general when southwest respondents consider large scale solar development in their county the influence of these variables changes so that property value race and age only yield influence differential effects occur for respondents of our national sample we believe our findings to be relevant for those outside the u s due to the considerable growth pv solar has experienced in the last decade especially in china japan germany and the u s

the inclusion of social aspects in power planning a b s t r a c t this paper overviews previous research addressing the inclusion of the social dimension of sustainable development on power systems planning consequences of the recent energy policies and strategies are already being felt in developed countries power systems with the integration of rising quotas in renewable energy technologies however while the tools that aid decision making on power planning show that economic and environmental issues are easily quantifiable and thus modeled social concerns have been addressed in a less extensive and more subjective way implying in most cases expert participation on multi criteria decision aid techniques a survey of recent papers providing public perceptions on electricity generation technologies and projects is presented these papers were chosen and reviewed in order to present a representative array of methodologies that are used to assess social acceptance of technologies according to some of the reviewed papers this issue is suggested to be fundamental to increase project success as a conclusion stands the fact that further discussion is still needed in order to achieve solid agreement among experts over what are the positive and the negative drivers to social sustainability otherwise models will not be able to translate reality and improve it under this point of view

sustainability assessment of electricity production using a logic models approach the topic sustainable development has brought a wide discussion across a number of sectors in our society namely in power systems given the need to address other concerns than the economic ones decision makers must take into account the rationale that lies beneath strategic choices such as investing in generation technologies using renewable energy or rather doing business as usual and installing fossil fuel power plants in this paper logic models were used as a decision aid supporting tool with the aim of contributing to the assessment of the possible impacts of different power plants in terms of sustainable development the analyzed electricity generation technologies were grouped in thermal renewable energy sources ress and nuclear the literature review fed the construction of three relational diagrams to allow the visualization of environmental social and economic causes and effects of the three groups of technologies departing from these initial diagrams a set of interviews with experts was conducted to enrich and validate the logic models the results of the literature review and of these interviews allowed to conclude that the use of res has wider positive social impacts on the long run despite their short term higher costs compared to the traditional groups nuclear and thermal these logic models revealed to be a useful tool providing a valuable starting approach for an impact assessment of the ongoing change that power systems have been going through

measuring consumerwelfareinthe cpu market anapplication of the pure characteristics demand model in this article i estimate demand for the personal computer central processing unit and measure consumer welfare using the pure characteristics demand model the model is based on a quasilinear utility function with multiplicative random variables and does not have the idiosyncratic logit error term so that consumer welfare directly reflects consumers valuation of product characteristics welfare calculations show that consumer surplus comprises approximately 90 of total social surplus and that large welfare gains have resulted from the introduction of new products

the fisher hypothesis and the interaction between share returns inflation and supply shocks abstract recent tests reject the fisher hypothesis even when expected income growth is accommodated in the estimates this paper suggests that the coefficient of expected inflation is biased downwards when supply shock variables are omitted from standard tests of the fisher hypothesis because they simultaneously affect inflation and real profits using data for 16 oecd countries over the past four decades it is shown that the fisher hypothesis cannot be rejected when supply shock variables are accommodated in the estimates

use of multicriteria decision analysis methods for energy planning problems most decision making requires the consideration of several conflicting objectives the term multiple criteria decision analysis mcda describes various methods developed for aiding decision makers in reaching better decisions energy planning problems are complex problems with multiple decision makers and multiple criteria therefore these problems are quite suited to the use of mcda a multitude of mcda methods exists these methods can be divided in three main groups value measurement models goal aspiration and reference level models and outranking models methods from all of these groups have been applied to energy planning problems particularly in the evaluation of alternative electricity supply strategies each of the methods has its advantages and drawbacks however we cannot conclude that one method generally is better suited than the others for energy planning problems a good alternative might be to apply more than one method either in combination to make use of the strengths of both methods or in parallel to get a broader decision basis for the decision maker until now studies of mcda in energy planning have most often considered energy networks with only one energy carrier more advanced energy systems with multiple energy carriers have been neglected even though this field ought to be suitable for use of mcda due to its high complexity many decision makers and many conflicting criteria

the welfare implications of unauthorized reproduction of intellectual property in the presence of demand network externalities this paper finds that unauthorized reproduction of intellectual property in the presence of demand network externalities can not only induce greater firm profits relative to the case where there is no copying it can lead to a pareto improvement in social welfare ceteris paribus when network externalities are present firms have a greater incentive to expand output because marginal revenue is higher and or they may wish to create preemptive installed bases this paper suggests that unauthorized copying can be a relatively efficient means of achieving this by allowing the firm in effect to price discriminate among different classes of consumers copyright 1994 by blackwell publishing ltd

relative price variability real shocks and the stock market in this paper we investigate the effects of relative price variability on output and the stock market and gauge the extent to which inflation proxies for relative price variability in stock return inflation regressions the evidence shows that the negative stock returninflation relations proxy for the adverse effects of relative price variability on economic activity particularly during the seventies when the u s experienced oil supply shocks hence it appears that inflation spuriously affects the stock market in two ways the aggregate output link of fama 1981 and the supply shocks reflected in relative price variability a number of papers have attempted to explain the anomalous negative relations between stock returns and inflation witnessed in the post war period one hypothesis that has held up well in light of empirical evidence suggests that the negative relation between stock returns and unexpected inflation simply reflects the more fundamental positive relation between stock returns and future real variables see e g fama 1981 geske and roll 1983 and kaul 1987 1989 in this paper we investigate the effects of relative price variability on output and the stock market and gauge the extent to which inflation proxies for relative price variability in stock return inflation regressions first relative price variability can have detrimental effects on output and employment see e g friedman 1977 and barro 1976 second absolute relative price confusion models of the lucas 1973 type suggest that monetary shocks can induce a positive relation between inflation and relative price variability see e g cukierman 1983 hence the negative stock return inflation relations could simply be a reflection of the negative effects of relative price variability on the stock market we use data for the 1947 1985 period to test the various links of our hypothesis the results indicate that relative price variability is positively related to both expected and unexpected inflation measures relative price variability also has a significant negative effect on output and the stock market more importantly

copying and indirect appropriability photocopying of journals creators and owners of intellectual properties are alarmed by the growth of technologies that ease the tasks of copying these properties this paper however shows that the unauthorized copying of intellectual properties need not be harmful and actually may be beneficial the empirical impact of photocopying on publishers of journals is examined in an attempt to discover if publishers can indirectly appropriate revenues from users who are not original purchasers the evidence indicates that publishers can indirectly appropriate revenues from users who do not directly purchase journals and that photocopying has not harmed journal publishers 18 references 1 table

five capital impact assessment appraisal framework based on theory of sustainable well being abstract this paper sets out to formulate an appraisal approach in context with sustainable development in conventional project appraisal such as energy undertakings most emphasis is placed on financial flows and rate of return on infrastructure investments although current greenhouse gas emissions are estimated to pose large costs on future generations these emissions are generally not estimated as part of the investment cost other public goods may also be omitted because their value is not recognized we review conventional cost benefit assessment and propose a new broader evaluation this new evaluation approach is based on the theory that five capital value types support long term well being rather than economic growth alone the theory states that humans depend on the size of stocks and flows from natural manufactured human social and financial capital we describe the five capitals to illustrate the value categories and outline an approach to evaluate all these in the context of energy development

how to model different socio economic and environmental aspects of biomass utilisation case study in selected regions in slovenia and croatia abstract wood biomass is an important renewable source of energy especially in countries with traditional dependency on forestry resources in these countries wood biomass can have numerous positive socio economical and environmental effects this paper presents a new model score model for estimation of 15 socio economic and environmental aspects of increased use of biomass from the forests the presented model enables selected estimation of different aspects in the whole chain of biomass production preparation and use namely the model enables the estimation of net labour income net profit regional public finance income net direct jobs net indirect jobs net induced jobs total net jobs contribution to forest management impact on wood waste utilisation impact on other woody biomass utilisation avoided costs of landfill saving co2 emissions possible impact on regional unemployment avoided costs of unemployment additional jobs for farmers additional activities on farms from indirect and induced jobs and self sufficiency in electricity production the score model was tested in selected regions in slovenia and croatia and apart from a good understanding of the socio economic and environmental aspects it also enables an overview of the economy of wood biomass production given that it includes the economic analysis of wood biomass production and use the model is not intended for a detailed economic analysis of separate phases of wood biomass production processing and use but particularly to show advantages or disadvantages that can result from planned and existing biomass systems

real interest rates and inflation an ex ante empirical analysis we develop a method of measuring ex ante real interest rates using prices of index and nominal bonds employing this method and newly available data we directly test the fisher hypothesis that the real rate of interest is independent of inflation expectations we find a negative correlation between ex ante real interest rates and expected inflation this contradicts the fisher hypothesis but is consistent with the theories of mundell and tobin darby and feldstein and stulz we also find that nominal interest rates include an inflation risk premium that is positively related to a proxy for inflation uncertainty

industry returns and the fisher effect we investigate the cross sectional relation between industry sorted stock returns and expected inflation and we find that this relation is linked to cyclical movements in industry output stock returns of noncyclical industries tend to covary positively with expected inflation while the reverse holds for cyclical industries from a theoretical perspective we describe a model that captures both i the cross sectional variation in these relations across industries and ii the negative and positive relation between stock returns and inflation at short and long horizons respectively the model is developed in an economic environment in which the spirit of the fisher model is preserved the fisher model states that expected nominal rates of return on assets should move one for one with expected inflation this belief is generally attributed to irving fisher s 1930 work on interest rates in particular to his view that the real and monetary sectors are causally independent in an apparent contradiction to the fisher hypothesis however it is a common empirical finding that stock returns are negatively related to both expected and realized inflation 1 this negative correlation is especially surprising for stocks which as claims against real assets should compensate for movements in inflation we provide two main contributions to the existing literature on the relation between stock returns and inflation the first contribution of the article is to provide a theoretical description of the cross sectional relation between stock returns and expected inflation we describe an asset pricing model that predicts cross sectional variation in the coefficients of expected inflation across various industry portfolios an interesting feature of the model is that it synthesizes some of the more palatable features of existing explanations of the negative relation between inflation and returns of special interest is the development of the model in a money neutral world so that the basic premise underlying fisher s work is maintained since most theoretical models of the

indexation and the effect of inflation uncertainty on real gnp this article examines the combined effects of inflation uncertainty and indexation on the growth rate of real gross national product gn p the evidence suggests that greater indexation partially reduces t he adverse effect of inflation uncertainty on real gnp growth over time it also indicates that in contrast to earlier findings regarding th e effect of inflation uncertainty on employment the overall effect of inflation uncertainty on real gnp growth may be permanent a preliminary assessment of whether the discrepancy is the result of in flation uncertainty permanently affecting the growth rate of the capi tal stock is inconclusive copyright 1988 by the university of chicago

assessment of sustainability indicators for renewable energy technologies the non combustion based renewable electricity generation technologies were assessed against a range of sustainability indicators and using data obtained from the literature the indicators used to assess each technology were price of generated electricity greenhouse gas emissions during full life cycle of the technology availability of renewable sources efficiency of energy conversion land requirements water consumption and social impacts the cost of electricity greenhouse gas emissions and the efficiency of electricity generation were found to have a very wide range for each technology mainly due to variations in technological options as well as geographical dependence of each renewable energy source the social impacts were assessed qualitatively based on the major individual impacts discussed in literature renewable energy technologies were then ranked against each indicator assuming that indicators have equal importance for sustainable development it was found that wind power is the most sustainable followed by hydropower photovoltaic and then geothermal wind power was identified with the lowest relative greenhouse gas emissions the least water consumption demands and with the most favourable social impacts comparing to other technologies but requires larger land and has high relative capital costs

evidence of the fisher effect from u k indexed bonds newly available data from the u k market for indexed securities are used to test the fisher hypothesis for monthly observations of interest rates at 14 maturities the hypothesis that the after tax nominal interest rate is a constant plus anticipated inflation proves to be a reasonable approximation of reality for longer maturities the coefficients on the expected rate of inflation are approximately equal to one the mundell tobin effect is in evidence for shorter maturities the inverted fisher effect is in evidence for shorter maturities the inverted fisher effect is decisively rejected the evidence suggests that past difficulties encountered in trying to prove the fisher effect have been due to the lack of a direct measure of inflation expectations and real interest rates copyright 1992 by mit press
