cleaner energy for sustainable future this special issue of the journal of cleaner production focuses on energy for sustainable future it is designed to mirror the increasing relevance of renewable energy sources and improved efficiency as crucial topics for practitioners in industry for governmental policy makers as well as for civic service providers researchers and educators the purpose of this special issue is to serve as a catalyst for dialogue the global warming related to co2 emissions coupled with steeply rising energy prices and the recent global financial institutional melt down are causing massive societal concerns and give rise to increasing demand for ways to improve societal and individual energy efficiency and for ways to shift increasingly to alternative low or non carbon based energy systems until recently industrial energy efficiency improvements have focused on improvements on efficiency rather than on the integration of renewable sources the aim of this special issue is the identification of policies to support the development and implementation of technologies and management approaches we can employ to make the transition to more sustainable societies the collection of papers in this special issue provide a foundation for students researchers scholars practitioners and policy makers interested in making sustainable development more than a metaphor the papers include focus upon ways for a improving industrial process to achieve improvements in energy efficiency b minimising waste disposals and reducing their impact through better management c reducing co2 emissions by making progress toward lower carbon renewable energy based systems d improving production of biofuels and hydrogen production systems facilitated by employing cleaner production and novel lca tools e improving integration of advanced materials and energy efficient equipment in different industrial sectors current and future developments in national and world economies are closely connected to sustainable efficient and safe usage of raw materials and upon energy based on cleaner production concepts and approaches that are ecologically and economically appropriate for the short and for the long term future of society these challenges have received considerable attention in the media and scientific journals over the last several years the idea of developing a specialised conference focussed upon them was put forward on various occasions focus upon them became reality on the 5th and 6th may 2008 in the historic castle of veszprem hungary the current premises of the hungarian academy of science which hosted the workshop the workshop was a stimulating event and an overwhelming success with nearly 100 contributors from africa north america asia and europe representing 28 countries after a comprehensive selection and thorough reviewing procedure 11 papers were selected for this special issue

the bond old bond spread abstract i document the profits on a trade that is long the old 30 year treasury bond and short the new 30 year treasury bond and is rolled over every auction cycle from june 1995 to november 1999 despite the systematic convergence of the spread over the auction cycle the average profits are close to zero the difference in repo market financing rates between the two bonds is a significant cost of carry in this trade i show that variation in the bond old bond spread is driven by the treasury supply of 30 year bonds as well as aggregate factors affecting investors preference for liquid assets

energy security and renewable electricity trade will desertec make europe vulnerable to the energy weapon abstract solar power imports to europe from the deserts of north africa as foreseen in the desertec concept is one possible way to help decarbonising the european power sector by 2050 however this approach raises questions of threats to european energy security in such an import scenario particularly in the light of increasing import dependency and russia s use of the energy weapon in recent years in this paper we investigate the threat of north african countries using the desertec electricity exports as an energy weapon we develop and use a new model to assess the interdependence the bargaining power symmetry operationalised as costs of a disruption in a future renewable electricity trade between north africa and europe if europe maintains current capacity buffers some demand response capability and does not import much more than what is described in the desertec scenario it is susceptible to extortion and political pressure only if all five exporter countries unite in using the energy weapon europe is not vulnerable to extortion by an export cut from only one country as the european capacity buffers are sufficient to restore the power supply no single exporter country would have sustained bargaining power over europe

too big to ignore hedge fund flows and bond yields abstract this paper investigates the information content of aggregate hedge fund flow and its predictive power with respect to bond yields using a sample of 9725 hedge funds from 1994 to 2012 we find that fund flow is negatively related to the changes in 10 year treasury and moody s baa bond yields one month ahead this relation is still pronounced after controlling for other determinants of yield changes including the amount of arbitrage capital available in the economy suggesting a non trivial effect of flow induced hedge fund trading on bond yields flow impact on corporate bonds is further amplified during periods of decreasing market liquidity consistent with a fire sale hypothesis hedge fund flow also predicts convergence between constant maturity swap rate and constant maturity treasury rate as well as between the tips and treasury bond yields suggesting that hedge funds exploit arbitrage opportunities in these fixed income markets

new keynesian models durable goods and collateral constraints abstract econometric evidence suggests that in response to monetary policy shocks durable and non durable spending co move positively and durable spending exhibits a much larger sensitivity to the shocks a standard two sector new keynesian model with perfect financial markets is at odds with these facts the introduction of a borrowing constraint where durables play the role of collateral assets helps in reconciling the model with the empirical evidence

an expository note on individual risk without aggregate uncertainty abstract in economies where agents bear some risk the analysis would often be facilitated by the assumption that the risks are i i d and disappear in the aggregate a formal appeal to the law of large numbers requires the consideration of a sequence of finite economies in an economy with a continuum of agents there are countable families of sets for which it is impossible for a law of large numbers to be valid with countably many agents and a finitely additive measure independence is compatible with the law of large numbers

habit formation in consumer preferences evidence from panel data this paper tests for the presence of habit formation using household data a simple model of habit formation implies a condition relating the strength of habits to the evolution of consumption over time when the condition is estimated with food consumption data from the panel study on income dynamics the results yield no evidence of habit formation at the annual frequency this finding is robust to a number of changes in the specification it also holds for several proxies for nondurables and services consumption created by combining psid variables with weights estimated from consumer expenditure survey data

notes on the theory and evidence on aggregate purchases of durable goods the basic implications of the frictionless permanent income hypothesis for durable goods purchases are strongly rejected by the data at the aggregate level there is too much inertia at the macroeconomic level purchases are too infrequent and lumpy in principle these rejections can be simultaneously rationalized by the presence of fixed costs of adjustment at the microeconomic level this article provides a simplified overview of recent developments attempting to formalize and measure the implications of models of fixed cost of adjustment for microeconomic and especially aggregate behavior of expenditure on durable goods it contends that these efforts have paid off in terms of methodological and empirical improvements copyright 1994 by oxford university press

permanent and transitory movements in labor income an explanation for excess smoothness in consumption many have argued that if labor income is difference stationary the permanent income hypothesis predicts that consumption should be relatively volatile in u s aggregate data labor income is well characterized as having a unit root however consumption turns out to be relatively smooth this anomaly is known as deaton s paradox i resolve deaton s paradox by providing decompositions of labor income into permanent and transitory components these preserve the univariate dynamic properties of labor income however when agents distinguish permanent and transitory movements in their labor income as the rational expectations hypothesis asserts they should the permanent income hypothesis correctly predicts the observed smoothness in consumption

consumer durables and inertial behaviour estimation and aggregation of s s rules for automobile purchases the s s model originally introduced in the study of inventories see arrow et al 1951 scarf 1959 has recently received renewed attention both in the durable consumption and in the investment and labour demand literatures caballero 1993 for instance appeals to these type of models to explain the time series properties of durable expenditure and in particular the persistence or slow adjustment of such a variable in this paper i model the purchase behaviour of automobiles by u s households as an s s rule i estimate a flexible specification of such a rule using a large microeconomic data set and study some of the aggregate implications of this type of inertial behaviour the paper is one of the first attempts at estimating directly the parameters of an s s rule using micro data because of this some of the methodological issues concerning the specification and the estimation of s s rules are relevant for many potential applications furthermore the paper is one of the first to discuss and quantify the aggregate implications of an s s rule estimated on micro data in the presence of non convex transaction costs a full and consistent characterization of individual behaviour is very hard and typically requires strong restrictions grossman and laroque 1991 prove that an s s rule is optimal for a consumption and investment problem under very special circumstances some of their results were extended by eberly 1991 and beaulieu 1993a b eberly 1991 in particular has derived some closed form solutions for durable consumption in the presence of transaction costs while caballero and engel 1994 construct a model of investment where an s s rule is optimal the main problem with these theoretical results is that it is only possible to show optimality of s s rules under very stringent conditions in particular a necessary condition to derive them is that the optimization problem faced by an individual consumer can be reduced to a problem with a single state variable unfortunately as pointed out by bar ilan and blinder 1992 even simple generalizations are extremely difficult to analyse

slow information diffusion and the inertial behavior of durable consumption this paper studies the aggregate dynamics of durable and nondurable consumption under slow information diffusion sid due to noisy observations and learning within the permanent income framework we show that sid can significantly improve the model s predictions on the joint behavior of income durable consumption and nondurable consumption at the aggregate level specifically we find that sid can significantly improve the model s predictions for i smoothness in durable and nondurable consumption ii autocorrelation of durable consumption and iii contemporaneous correlation between durable and nondurable consumption furthermore we discuss that incorporating a fixed cost into our sid model does a better job of reproducing the infrequent adjustments of durable consumption at the individual level and the slow adjustments at the aggregate level

permanent income liquidity and adjustments of automobile stocks evidence from panel data a recent article by bernanke 1984 tests the rational expectations permanent income hypothesis using panel data on automobile expenditures he finds no evidence refuting the hypothesis this paper incorporates a threshold adjustment process into bernanke s model estimations based on a subset of the data used by bernanke reveal evidence that resale market imperfections and credit market constraints have important effects on automobile expenditures

development of supersmart grids for a more efficient utilisation of electricity from renewable sources abstract if europe is serious about reaching its target to keep global mean temperature increase below 2 c it must strive for a 100 renewable electricity system by 2050 the supersmart grid approach combines what is often perceived as two exclusive alternatives wide area power generation and decentralised power generation we argue that by combining these in fact complementary measures it is possible to address the crucial issue of renewable generation fluctuating supply in a comprehensive as well as in a technologically and economically viable manner thus the supersmart grid simultaneously can contribute to energy security climate security social security and national security

expenditure on durable goods a case for slow adjustment for more than a half a decade the fact that expenditure on durables can be well approximated by a random walk has remained a hidden puzzle challenging almost any theory in which agents smooth the use of their wealth this paper shows that once a nonparsimonious approach is used or lower frequencies of the data are examined the fact itself disappears changes in expenditures on durables reveal a degree of reversion consistent with the permanent income hypothesis pih although this reversion occurs at a rate significantly slower than what is suggested by a frictionless pih model

the tips treasury bond puzzle we show that the price of a treasury bond and an inflation swapped treasury inflation protected securities tips issue exactly replicating the cash flows of the treasury bond can differ by more than 20 per 100 notional treasury bonds are almost always overvalued relative to tips total tips treasury mispricing has exceeded 56 billion representing nearly 8 of the total amount of tips outstanding we find direct evidence that the mispricing narrows as additional capital flows into the markets this provides strong support for the slow moving capital explanation of arbitrage persistence

electricity capacity investment under risk aversion a case study of coal gas and concentrated solar power the policy instrument many economists favor to reduce greenhouse gas emissions and to shift new investment towards low carbon technologies is the tradable allowance system experience with this instrument has been mixed with a crucial design issue being the choice of whether to auction allowances to firms or to grandfather them based on historical emissions in this paper we examine the changing incentives of investment in different technologies when investors are risk averse and are expecting an allowance system with a certain allocation rule but do not know if the policy is going to take place in the near future investors also cannot fully predict future investment costs for the low carbon technology we apply a game theoretic model to examine the combined effects of uncertainty and risk aversion on the actions of potential investors into high and low carbon generating capacity under both allocation rules and uncertain costs we find that uncertainty and risk aversion do have implications towards investment incentives we discuss policy implications of these findings

an econometric model of serial correlation and illiquidity in hedge fund returns the returns to hedge funds and other alternative investments are often highly serially correlated in sharp contrast to the returns of more traditional investment vehicles such as long only equity portfolios and mutual funds in this paper we explore several sources of such serial correlation and show that the most likely explanation is illiquidity exposure i e investments in securities that are not actively traded and for which market prices are not always readily available for portfolios of illiquid securities reported returns will tend to be smoother than true economic returns which will understate volatility and increase risk adjusted performance measures such as the sharpe ratio we propose an econometric model of illiquidity exposure and develop estimators for the smoothing prole as well as a smoothing adjusted sharpe ratio for a sample of 908 hedge funds drawn from the tass database we show that our estimated smoothing coecien ts vary considerably across hedge fund style categories and may be a useful proxy for quantifying illiquidity exposure

energy management on industrial parks in flanders in the race against climate change aiming for low carbon competitiveness flanders has initiated a carbon neutrality strategy on industrial parks building towards energy efficient buildings and processes acting as a stimulus for the production and consumption of green electricity however premises and internal process optimisation on industrial parks is not considered sufficient to limit greenhouse emissions in flanders structural transition is called for aiming for industrial clustering and energy autonomy based on renewables therefore the concept of industrial symbiosis is analysed to determine how it could improve the energy related carbon management on industrial parks this article explores the literature on industrial symbiosis and eco industrial parks searching for specific energy strategies and is illustrated with case studies energy management on industrial parks can be integrated in the entire development process and park management maximising efficiency is a promising local optimisation issue in which business should be engaged stimulated and facilitated by clustering buildings and processes by energy exchange collective production and joint contracting of energy services local synergies can be intensified yet uncertainty and variability in time of energy consumption can keep developers from tailoring industrial park design and utilities instead flexibility and solidity could be gained and the offer of business space could be diversified supported by a persevering issuing procedure to join similar and matching energy profiles energy management on industrial parks in flanders has only recently started but is expected to gain professionalism however further research is needed on this flexible design and thermal planning

margins and hedge fund contagion funding risk measures the extent to which a fund can borrow money by posting collateral using a novel measure of funding risk based on futures margins we are able to empirically identify the mechanism by which changes in funding risk affect the likelihood of contagion an increase in margins of the order of magnitude observed during the subprime crisis increases the probability of contagion among certain types of funds by up to 34 our analysis shows that some types of hedge funds are more vulnerable to contagion than others our results also suggest that policies that limit the magnitude of changes in margins over short periods of time may reduce the likelihood of contagion among hedge funds

potential capability estimation for real time electricity demand response of sustainable manufacturing systems using markov decision process abstract electricity demand response has been considered as a critical methodology to realize the strategy of sustainable development for manufacturing enterprises by effectively reducing the increasing electricity demand and greenhouse gas emissions most existing studies about the electricity demand response implementation focus on either the supply side management e g policy making price setting or the customer side applications for the end users in residential and commercial building sectors as for the industrial sector only a few papers utilizing the long term scheduling methodology to reduce the electricity consumption during peak periods are available little work has been implemented on the decision making for the real time electricity demand response in industrial manufacturing systems considering system throughput constraint in this paper an analytical model is established to identify the optimal energy control actions and estimate the potential capacity of power demand reduction of typical manufacturing systems during the period of demand response event without compromising system production markov decision process is used to model the complex interaction between the adopted demand control actions and the system state evolutions a numerical case study on a section of an automotive assembly line is used to illustrate the effectiveness of the proposed approach

clean and secure power supply a system dynamics based appraisal abstract across the world the electricity industry is changing with the advent of renewable energy sources such as solar and wind power as these are exposed to intermittency seasonality and global climate variation policy makers concerns are now shifting towards security of supply in fact the industry confronts three conflicting goals security of supply competitive prices to customers and environmental protection in this context and given the multiple uncertainties of technology transformation this paper uses modelling based scenario analysis to investigate different extreme and plausible futures simulation is used to analyse policies aimed at increasing the penetration of renewables and to explore how these energy sources may affect system reliability this paper explores the effect of incorporating renewables in colombia where a large hydroelectric component has led to insufficient electricity being available during droughts and to high electricity price volatility though not intuitive at first glance this paper shows that renewables may contribute to i increased security of supply through complementarity e g it does not rain when the sun shines ii reduced price volatility in the medium term and iii increased industry sustainability

solar power investment in north africa reducing perceived risks abstract climate protection targets for mid century imply a need to scale up european renewable power production to a level that may exceed the available land area within europe s borders one attractive solution from a cost and feasibility perspective is the development of large scale concentrating solar power plants in north africa and the middle east however these developments are seen by many people as risky in terms of both european energy security and in terms of the risks faced by project developers in this paper we focus on the latter of theses issues first we examine the risks that project developers are most concerned about and identify these as being associated not with terrorism and rogue state behavior but rather with corruption and inefficient and unpredictable bureaucracies second we identify a range of policy approaches that can reduce these risks either by mitigating their consequences or by seeking to eliminate their underlying causes third we investigate the financial benefits of taking such steps to reduce or eliminate investment risks we find the potential savings to european electricity consumers to exceed 200 billion

do hedge fund managers misreport returns evidence from the pooled distribution we find a significant discontinuity in the pooled distribution of monthly hedge fund returns the number of small gains far exceeds the number of small losses the dis continuity is present in live and defunct funds and funds of all ages suggesting that it is not caused by database biases the discontinuity is absent in the 3 months culminating in an audit suggesting it is not attributable to skillful loss avoidance the discontinuity disappears when using bimonthly returns indicating a reversal in fund performance following small gains this result suggests that the discontinuity is caused at least in part by temporarily overstated returns

performance characteristics of hedge funds and commodity funds natural vs spurious biases it is well known that the pro forma performance of a sample of investment funds contains biases these biases are documented in brown goetzmann ibbotson and ross 1992 using mutual funds as subjects the organization structure of hedge funds as private and often offshore vehicles makes data collection a much more onerous task amplifying the impact of performance measurement biases theis paper reviews these biases in hedge funds we also propose using funds of hedge funds to measure aggregate hedge fund performance based on the idea that the investment experience of hedge fund investors can be used to estimate the performance of hedge funds

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

macroeconomic expectations of households and professional forecasters economists have long emphasized the importance of expectations in determining macroeconomic outcomes yet there has been almost no recent effort to model actual empirical expectations data instead m acroeconomists usually simply assume that expectations are rational this paper shows that while empirical household expectations are not rational in the usual sense expectational dynamics are well captured by a model in which households views derive from news reports of the views of professional forecasters which in turn may be rational the model s estimates imply that people only occasionally pay attention to news reports this inattention generates stickyness in aggregate expectations with important macroeconomic consequences

a theory of demand shocks this paper presents a model of business cycles driven by shocks to consumer expectations regarding aggregate productivity agents are hit by heterogeneous productivity shocks they observe their own productivity and a noisy public signal regarding aggregate productivity the public signal gives rise to noise shocks which have the features of aggregate demand shocks they increase output employment and inflation in the short run and have no effects in the long run numerical examples suggest that the model can generate sizable equilibrium dsge models of the business cycle include a large number of shocks to technol ogy monetary policy preferences etc but typically do not include expectational shocks as independent drivers of short run fluctuations 1 this paper explores the idea of expectation driven cycles looking at a model where technology determines equilibrium output in the long run and consumers receive noisy signals about technology in the short run the presence of noisy signals produces expectational errors this paper studies the role of these expectational errors in gener ating volatility at business cycle frequencies the model is based on two ingredients first consumers take time to recognize permanent changes in aggregate fundamentals although they may have good information on the current state of the individual firm or sector where they operate they have only limited information regarding the long run determinants of aggregate activity second consumers have access to public information that is relevant to estimate long run productivity this includes news about technological innovations publicly released macroeconomic and sectoral statistics financial market prices and public statements by policy makers however these signals provide only a noisy forecast of the long run effects of technological innovations this opens the door to noise shocks which induce consumers to temporarily overestimate or underestimate the productive capacity of the economy

simple rule for management of thermal loads with real time prices abstract the integration of renewable energies and therefore the generation of a clean and sustainable energy is a current demand by society the use of real time pricing offers advantages for integrating renewable resources into the electrical grid this is because users enhance the flexibility of their own energy demand thanks to planning loads with accumulation capacity the aim of the present work is to equip users to manage their energy demands with simple planning systems for this a simple rule is proposed to help a greater number of users to gain the capacity to manage their demand the new rule based on a geometric progression of real time pricing of energy and intrinsic characteristics of the load provides valuable information for the user to decide whether or not to accumulate energy in the load this rule provides good results by the simulation of a simple thermal load

variability of durable and nondurable consumption evidence for six o e c d countries the author estimates consumption variability ratios for both durable and nondurable consumption using data for six oecd countries his methodology which relies on a long run restriction implied by the consumer s intertemporal budget constraint overcomes many of the problems inherent to previous approaches some important departures from the permanent income model emerge 1 nondurable consumption shows mild excess smoothness in the united states and italy and mild excess volatility in japan and france and 2 durable consumption shows extreme excess smoothness in all countries alternative factors capable of generating the differences in volatility across types of goods are discussed copyright 1993 by mit press

socio economic acceptability for smart grid development a comprehensive review abstract a deep transformation of the electrical grid system at the global level is expected in the near future with new economic relations between energy suppliers and consumers this is the smart grid framework which can integrate the behavior of all connected users who become prosumers to ensure a sustainable energy supply in an efficient economical and safe manner smart grid projects have a significant impact on electricity consumers through shifts in consumer behavior culture and lifestyle the aim of this paper is to explore the degree of investigation of the main socio economic features in terms of private and social costs which are relevant for smart grids development and public acceptance to this aim a literature review of 148 peer reviewed scientific journal articles on smart grids has been conducted developing an original taxonomy for the socio economic features in terms of private direct costs directly associated with the monetary costs paid by consumers and social indirect costs constituted by consumers perception privacy cyber security and regulation the importance of the analysis of social costs arising from externalities is that they may hinder the deployment of specific technologies even if these technologies appear to be useful based on private costs the results reveal that the explored literature mainly deals with private costs although an emerging literature starts to address the social costs that may hamper smart grids deployment the paper reviews new opportunities and challenges for further research bridging the gap between engineering and socio economic research areas including business organizational applications policy and security issues the resulting enrichment of interdisciplinary know how can be the basis for the sustainable development of current and future generations

optimizing the production scheduling of a single machine to minimize total energy consumption costs abstract the rising cost of energy is one of the important factors associated with increased production costs at manufacturing facilities which encourages decision makers to tackle this problem in different manners one important step in this trend is to reduce the energy consumption costs of production systems considering variable energy prices during one day this paper proposes a mathematical model to minimize energy consumption costs for single machine production scheduling during production processes by making decisions at machine level to determine the launch times for job processing idle time when the machine must be shut down turning on time and turning off time this model enables the operations manager to implement the least expensive production scheduling during a production shift to obtain near optimal solutions genetic algorithm technology has been utilized furthermore to determine whether the heuristic solution provides the minimum cost and the best possible schedule for minimizing energy costs an analytical solution has also been run to generate the optimal solution next a comparison between the analytical solution and heuristic solutions is presented for larger problems the heuristic solution is preferable the results indicate that significant reductions in energy costs can be achieved by avoiding high energy price periods this minimization process also has a positive environmental effect by reducing energy consumption during peak periods which increases the possibility of reducing co 2 emissions from power generator sites

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

the potential and economics of bioenergy in finland abstract this article summarises the results from four studies on the potential of bioenergy and one study on the economic feasibility of distributed renewable energy production in ostrobothnia finland the scope of the studies was to explore the degree of energy self sufficiency that could be achieved and the economic implications and benefits the results suggest that a great majority of rural areas have the potential for being self sufficient in their energy production through bioenergy alone but other renewable energy sources res including for example wind and solar power will make an even greater contribution in the future this applies to areas especially outside the largest population centres and most energy intensive industries indeed in peripheral regions the renewable energy potential far exceeds the energy demand and the spatial coverage of energy self sufficiency is huge other european and global studies also show tremendous res potential the economics of small scale power generation units here represented by biogas plants are already feasible despite the technology still being at an early developmental phase diffusion of these technologies depends on a number of factors but single and separate units are emerging all the time the adoption of res based energy management systems will however be a long social process the results give rise to an expectation for more res based energy generation in ostrobothnia and finland and even in europe and globally in a time frame of 20 30 years this development may result in structural changes across the whole energy sector this comprehensive movement can only be understood and supported by multi and cross scientific approaches and it will in future be a challenge for forthcoming research
