directed matching and monetary exchange we develop a model of monetary exchange where as in the random matching literature agents trade bilaterally and not through centralized markets rather than assuming they match exogenously and at random however we determine who meets whom as part of the equilibrium we show how to formalize this process of directed matching in dynamic models with double coincidence problems and present several examples and applications that illustrate how the approach can be used in monetary theory some of our results are similar to those in the random matching literature others differ significantly

declining values and the afternoon effect evidence from art auctions we study the order of sale in art auctions the final bid relative to the auctioneer s estimated price declines throughout the course of an auction a theoretical model shows that in an auction ordered by declining valuation even in the presence of risk neutral strategic bidders the price received relative to the estimate for later items in an auction should be less than the price relative to the estimate for earlier items furthermore ordering heterogeneous items by value maximizes revenue for the auctioneer

evaluation of european lighting programmes utilities finance energy efficiency abstract the beginning of least cost utility planning in europe is marked by 42 recent programmes offering financial incentives to encourage the use of energy efficient compact fluorescent lamps cfls programmes have been conducted in six countries and manufacturers retailers and governments played active roles most of the programmes targeted residential consumers but eight were available to commercial or industrial customers incentives included various combinations of give aways direct installation rebates wholesale discounts and schemes in which consumers can gradually pay for their lamps via the utility bill during the programmes almost six million eligible households acquired two million cfls the average societal cost of conserved electricity was c2 1 kwh including 0 3 kwh for indirect administrative promotional and evaluation costs these programmes were cost effective compared to the price of electricity or to the cost of new electric power plants increased demand for cfls has helped to lower post programme retail lamp prices by 20 to 50 for all consumers the programme experiences shed light on a number of challenges for planners and policymakers

sequential auctions price trends and risk preferences abstract we analyze sequential auctions in a general environment where bidders are heterogeneous in risk exposures and exhibit non quasilinear utilities we derive a pure strategy symmetric equilibrium for the sequential dutch and vickrey auctions respectively with an arbitrary number of identical objects for sale when bidders are risk averse preferring the equilibrium price sequences must be downward upward drifting the declining price anomaly is thus evidence of bidder risk aversion in this general environment these results derive from a key assumption that bidders marginal utilities are log supermodular in payment and type

sequential auctions with informational externalities and aversion to price risk decreasing and increasing price sequences a large body of empirical research has shown that prices of identical goods sold sequentially sometimes increase and often decline across rounds this article introduces a tractable form of risk aversion called aversion to price risk and shows that declining prices arise naturally when bidders are averse to price risk when there are informational externalities there is a countervailing effect which pushes prices to raise along the path of a sequential auction even if bidder s signals are independent the article shows how to decompose the effect of aversion to price risk from the effect of informational externalities

determinants and welfare of the environmental regulatory stringency before and after regulatory capture abstract the enforcement of environmental regulation relies on the willingness and capacity of the regulator the willingness could be disabled by regulatory capture which is widespread and that how many public resources should be invested in environmental regulation is always debatable we develop a 3 stage game to analyze the nonlinear effects and mechanism of regulatory capture and regulatory capacity on environmental regulatory welfare our model suggests that the importance of the regional economy to government the firm size and the customer s disutility on pollution emissions will influence the possibility of regulatory capture furthermore the dynamic research suggests that when the regulatory capture is controlled with the improvement of governmental regulatory capacity the regulator s and customer s welfare continues to grow until the capacity achieves a threshold beyond the threshold the regulatory capacity will be redundant

testing for price anomalies in real estate auctions this paper reports on the results of an auction sale of 83 condominium apartment units in new jersey at the auction every unit was hammered down but unknown to the 2 348 registered bidders 40 of the sales fell through prices in the subsequent sale of condominium units in face to face negotiations resulted in identical units selling for 13 less than they fetched at auction and the discount was largest for those units hammered down early in the auction these results are inconsistent with the usual predictions from the theory of common value auctions and suggest that uninformed bidders in this auction may have been the subject of a winner s curse which generated considerable profit for the seller this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from ano this abstract was borrowed from another version of this item

economic analysis of upgrading aging residential buildings in china based on dynamic energy consumption and energy price in a market economy abstract this article employed a standard lcc to conduct economic analysis of upgrading the aging residential buildings in china according to the current situation an interest rate of 6 an inflation rate of 3 an increase rate of annual energy savings of 2 and an increase rate of electricity price of 2 were assumed in the method the results indicated that only relying on gradually increasing electricity price and governments subsidies was not enough after detailed analysis of the energy saving measures and the distribution of all benefits from building energy retrofit it was found that actually only 1 3 of original cost was spent only for energy savings the second 1 3 for both energy savings and good facade appearance and occupants should share the last 1 3 because even if without energy retrofit they would have to pay the part too the corresponding results proved that the first 1 3 of investment cost could be drawn back within the residue life cycle and so the investment could be accepted in a sheer market economy in the end a model about distribution of investment cost of and benefits was proposed to adapt the market economy to overcome the financial problems in china

region division of china s carbon market based on the provincial municipal carbon intensity abstract the difference of carbon trading prices among emission trading scheme pilots may hinder the unified carbon market that china s government plans to establish in 2017 to achieve this goal this study develops a regional carbon market mode based on the similarity of thirty provinces municipalities carbon intensity by the aid of logarithmic mean divisia index autoregressive and dynamic time warping models according to the dynamic clustering result we divide these provinces municipalities into three sub markets that are the western eastern and central markets furthermore we propose the carbon emission modes corresponding to each sub market namely the energy dependence mode western market sustainable economy mode eastern market and industrial upgrading mode central market briefly we suggest that the unified market should be firstly divided into some sub markets finally we propose some critical routes as well as corresponding managerial implications for establishing such unified market

the role of economic and policy variables in energy efficient retrofitting assessment a stochastic life cycle costing methodology abstract energy saving is a major policy objective worldwide and in the eu in particular evaluating the convenience of energy efficient investments however is complex this paper aims to apply stochastic life cycle costing to assess the economic value of energy efficient building retrofitting investments the proposed approach investigates how macroeconomic variables affect such an evaluation by explicitly taking into account their interdependent stochastic nature consequently the economic evaluation of an investment is itself stochastic thus expressing both its expected value and its inherent uncertainty and risk on this basis an illustrative case study is presented where alternative designs of the energy saving intervention are compared and a sensitivity analysis performed to identify the determinants of the lcc outcome and of its variability in terms of policy implications a tool providing a sounder evaluation of the convenience of such investments can suggest when and to what extent incentives may be appropriate to facilitate these investments and what possible financial instruments could be put forward in order to reduce the associated risk

electricity conservation policies and sectorial output in pakistan an empirical analysis abstract government of pakistan has taken several measures in recent years for conserving electricity to reduce its electricity shortfall in this context this study attempts to quantify the impact of different electricity conservation policies on value added of industrial and services sectors in pakistan results indicate that unanticipated shocks to electricity consumption and technical efficiency form a positive relationship while electricity price has a negative relationship with value added in industrial and services sectors in the long run direct electricity conservation policies and policies that aim at increasing electricity prices will have an adverse impact on value added of both the sectors policies that induce improvements in energy efficiency will have a positive impact on the sectorial output in the long run therefore the government should not pursue direct consumption curtailment polices to mitigate the electricity crisis rather steps should be taken to enhance energy efficiency in the economy this can be done by setting targets for reducing energy intensity in both the sectors moreover energy efficiency should be incorporated in the mainstream of energy policy and specific laws should be enacted to establish institutions and develop methods to help in effective conservation and efficient consumption of limited energy resources

techno economic analysis of a coal fired chp based combined heating system with gas fired boilers for peak load compensation abstract combined heat and power chp plants dominate the heating market in china with the ongoing energy structure reformation and increasing environmental concerns we propose gas fired boilers to be deployed in underperforming heating substations of heating networks for peak load compensation in order to improve both energy efficiency and environmental sustainability however due to the relatively high price of gas techno economic analysis is required for evaluating different combined heating scenarios characterized by basic heat load ratio therefore we employ the dynamic economics and annual cost method to develop a techno economic model for computing the net heating cost of the system considering the current state of the art of cogeneration systems in china the net heating cost is defined as the investment costs and operations costs of the system subtracted by revenues from power generation we demonstrate the model in a real life combined heating system of daqing china the results show that the minimum net heating cost can be realized at 0 75 with a cost reduction of 16 8 compared to coal heating alone since fuel cost is the dominating factor sensitivity analyses on coal and gas prices are discussed subsequently

a note on sequential auctions this note provides an explanation for the declining price anomaly in sequential second price auctions we illustrate how the average winning bids of risk neutral agents bidding for objects with valuations drawn from independent identical distributions are lower in later auctions than in earlier auctions when the objects are not identical we determine the optimal order in which they should be auctioned

economic analysis of energy saving renovation measures for urban existing residential buildings in china based on thermal simulation and site investigation abstract energy saving renovations of existing residential buildings have proven to be very helpful in alleviating the pressure of energy shortages and co 2 emission but an economic analysis of the measures by using a life cycle cost lcc method is very important and necessary to determine whether to implement them or not based on thermal simulation and site investigation the paper uses one urban existing residential building in hangzhou city of china as the subject building and analyzes the economic benefits from the energy saving renovation measures through the lcc method the findings clearly show that the investigation of the factual electricity consumption of the subject building is very important to predict accurately the energy saving effects and financial benefits of the measures for the building because of the great discrepancy between in fact and in thermal simulation of the heating and cool loads and the too cheap electricity price may hamper the development of energy saving implementations in residential sector in china

sequentially optimal auctions abstract in auctions where a seller can post a reserve price but if the object fails to sell cannot commit never to attempt to resell it revenue equivalence between repeated first price and second price auctions without commitment results when the time between auctions goes to zero seller expected revenues converge to those of a static auction with no reserve price with many bidders the seller equilibrium reserve price approaches the reserve price in an optimal static auction an auction in which the simple equilibrium reserve price policy of the seller mirrors a policy commonly used by many auctioneers is computed journal of economic literature classification numbers c78 d44 d82

envisioning shared goals for humanity a detailed shared vision of a sustainable and desirable usa in 2100 economics has been defined as the science of allocation of scarce resources towards alternative ends this definition implies that the first step in economic analysis is to determine what ends are desirable for society most sectors of the society would agree that sustainability is a desirable end but there is little agreement as to what a sustainable future would look like the university of maryland institute for ecological economics sponsored a democratic future search process designed to create a relatively detailed shared vision of a sustainable and desirable usa in the year 2100 this paper presents the vision developed at that conference examines the resources required to achieve the vision and assesses the suitability of market mechanisms for allocating the required resources towards the desired ends we find that markets are not efficient mechanisms for allocation in this case and propose the institutions of a strong democracy as a promising alternative 2002 elsevier science b v all rights reserved

the declining price anomaly abstract data from wine auctions indicate that identical products sold sequentially typically follow a decreasing pattern of prices known as the declining price anomaly this is explained for both first and second price auctions by appealing to risk averse bidders earlier bids are then equal to expected later prices plus a risk premium associated with the risky future price we show that this logic rests on the assumption of nondecreasing absolute risk aversion which is necessary for pure strategy equilibrium bidding functions to exist thus decreasing absolute risk aversion implies ex post inefficiency with positive probability data from wine auctions are used to confirm the existence of the declining price anomaly journal of economic literature classification numbers d43 d44 d81 d82 l81

risk aversion and optimal reserve prices in first and second price auctions abstract we analyze the effects of buyer and seller risk aversion in first and second price auctions in the classic setting of symmetric and independent private values we show that the seller s optimal reserve price decreases in his own risk aversion and more so in the first price auction the reserve price also decreases in the buyers risk aversion in the first price auction thus greater risk aversion increases ex post efficiency in both auctions especially that of the first price auction at the interim stage the first price auction is preferred by all buyer types in a lower interval as well as by the seller

a dynamic school choice model this paper inspires from a real life assignment problem faced by the mexican ministry of public education we introduce a dynamic school choice problem that consists in assigning positions to overlapping generations of teachers from one period to another teachers can either retain their current positions or choose a preferred one in this framework a solution concept that conciliates the fairness criteria with the individual rationality condition is introduced it is then proved that a solution always exists and that it can be reached by a modified version of the deferred acceptance algorithm of gale and shapley we also show that the mechanism is dynamically strategy proof and respects improvements whenever the set of orders is lexicographic by tenure

catalogue vs order of sale effects in sequential auctions theory and evidence from a rare book sale we examine bidding in a rare book sequential auction that has features of a natural experiment lots were arranged in alphabetical order the reserve set non strategically and half the bids placed by mail in bidders we distinguish between the effects induced by the print order of the catalogue from those by the sequential nature of the sale we document the existence of distinct catalogue effects on prices number of bids and price variability and determine their causes we demonstrate that these catalogue effects also influence floor bidder behaviour we derive a theoretical model that generates key aspects of floor bidder behaviour copyright 2004 royal economic society

economic potential of energy efficient retrofitting in the swiss residential building sector the effects of policy instruments and energy price expectations the aim of this paper is to analyse the profitability of energy efficient retrofit investments in the swiss residential building sector from the house owner s perspective different energy price expectations policy instruments such as subsidies income tax deduction and a carbon tax as well as potential future cost degression of energy efficiency measures were taken into account the discounted cash flow method was used for the investment analysis of different retrofit packages applied to a model building scheduled for renovation i e a single family house constructed between 1948 and 1975 the results show that present swiss policy instruments push investments for energy efficient retrofitting to profitability cost degression has a minor significance for investment profitability however the most relevant factor for the investment analysis is the expected energy price expecting a future fuel oil price at the level of 2005 efficiency investments are close to profitability even without policy support if higher energy prices were expected energy efficient retrofitting would be an attractive investment opportunity

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

perfect equilibria in budget constrained sequential auctions an experimental study this article presents an experimental study of bidding behavior in sequential auctions in which there are budget constraints and perfect information our experiments test both the properties of such auctions and the predictive power of a refinement of the nash equilibrium concept we find that budget constraints affect the behavior of bidders and that the trembling hand perfect equilibrium is generally a good predictor of prices

uniqueness of equilibrium in sealed high bid auctions abstract for the case of two buyers we show that equilibrium in the sealed high bid auction is unique when i buyers reservations prices are drawn independently from distributions with finite support and positive mass at the lower endpoint ii buyers have private values and iii buyers preferences are log supermodular for more than two buyers we obtain the same result under the additional assumptions that iv buyers with the same reservation price have the same preferences v buyers are risk neutral or risk averse with non increasing absolute risk aversion and vi the supports of the different buyers distributions of reservation prices have the same upper endpoint

a new unified approach to evaluate economic acceptance towards main green technologies using the meta analysis the aim of this paper is to analyze the main determinants of the economic acceptability of four green technologies gts alternative fuel vehicles energy savings in residential buildings smart meters and renewable electricity using a meta analysis on a sample of 35 selected papers which provided 245 primary data this approach allows detecting relationships across heterogeneous studies avoiding the subjectivity of qualitative surveys we implement a new two step procedure first we compute a measure of the implicit price for a kilogram of co2 avoided pco2 homogenizing the usable information for the gts considered second we conduct a meta regression using the computed pco2 values to estimate the socio economic determinants impact in general our results show a wide degree of acceptability for gts which is stronger among european citizens in particular it emerges that on average the estimated pco2 is positive for the gts considered and additional positive effects exist when respondents are confronted with an explicit reference to quantitative targets in terms of co2 abatement a clear proposal for payment timing and a specific renewable electricity mix these results indicate that information and transparency are crucial to spur gts deployment therefore to support gts market penetration public and private institutional stakeholders have to provide ad hoc information to the end users setting a clear and suitable system of prices to increase the economic value end users place on gts

the shading and distancing of commerce when internalization is not enough abstract a political economy of degradation and of sustainability should account not only for the full range of production costs but the sources of those costs it should consider how the pursuit of wealth can deliberately or not lead to uncounted costs and unaccountable actors this article explores the conditions of cost generation and externalization especially those that are largely unintended and inadvertent it shows how the pursuit of wealth the expansion of markets the mobility of capital and the entanglements of production processes can lead to the unwitting generation and displacement of costs it analyzes competitive business strategy and patterns of production and consumption for their contribution to such costs business strategy and state policy tend to create a never ending search for frontiers however simulated and however unecological they may be the costs generated in those frontiers are a function of shading that is obscuring of costs and distancing the separation of production and consumption decisions both of which impede ecological and social feedback and create cognitive institutional and ethical lags between initial benefits and eventual full costs as distance increases along dimensions of geography culture bargaining power or agency negative feedback loops are severed stakeholders expand while decision making contracts environmental problems are displaced and shading and cost externalization increase the likelihood of sustainable resource use increases as distance is lowered as institutions locate decision authority in those who receive negative ecological feedback and who have the capacity and incentives to act on that feedback and as the burden of proof for economic interventions shifts to the interveners

efficiency effectiveness and implementation feasibility of energy efficiency rebates the renove plan in spain abstract state sponsored incentive policies frequently include subsidies or rebates for the purchase of more efficient appliances however more research is required into the effects of this tool in isolation a case in point is the so called renove plan in spain first the inefficiency losses dead weight losses associated with energy efficiency rebates must be taken into account such a policy may also encourage the large scale purchasing of energy efficient appliances which may finally result in an increase in electricity consumption rebound effect furthermore although a subsidy is more widely accepted than other tools from social and political viewpoints especially than taxes the fiscal consolidation challenge faced by many countries reduces the scope for environmental policy measures on the expenditure side of the budget and strengthens the need to use taxes to meet the agreed policy objectives this paper shows that the current application of the spanish renove plan with rebates on the dishwasher market for energy efficient appliances generates some welfare losses a rebound effect and a considerable deficit in public budgets the paper examines and assesses the effect of different combinations of taxes and rebates in the case of dishwashers in spain based on their performance in terms of economic efficiency environmental effectiveness and implementation feasibility

an imbalanced development of coal and electricity industries in china china s coal and electricity industries have a strong reliance on each other however because of excessive invasion of government it is difficult for these two industries to form a stable reasonable and transaction cost saving relationships but long run disputes and quarrels this paper discusses the pricing policies and transaction relationship between these two industries from the historical perspective it begins with the discussion of coal coal market has become competitive since 1980 due to the system of dual track approach but coal sold to electricity was still tightly controlled by government guided pricing then the paper examines electricity investment and tariff reform unlike coal entry to electricity generation sector was gradually relaxed but generation and retailing tariffs are still strictly regulated as energy demand and prices soared after 2002 coal and electricity enterprises are all unsatisfied with the rule of price setting of coal sold to electricity industry this paper concludes that the deliberate low coal price policy does protect electricity industry from fuel cost fluctuation but harm coal industry allocative and productive efficiency are difficult to achieve in the long run

firm size government capacity and regional environmental regulation theoretical analysis and empirical evidence from china abstract the size and number of firms in a region represent key characteristics of that regional economic ecosystem but few studies have linked such characteristics with the stringency of local environmental regulation in this study we discuss the effects of local firm scale on environmental regulation and its mechanism and the optimal strategic choices theoretically and empirically for environmental regulation in regions with different firm scale we find that when government capacity is insufficient regional environmental regulation will be relatively more stringent when dealing with fewer but larger firms because of the government scale effect when government capacity is sufficient firm size has no influence on environmental regulation our results are robust and offer insights for government decision makers to improve local environmental regulation efficiency

time horizons lattice structures and welfare in multi period matching markets abstract we analyze a t period two sided one to one matching market without monetary transfers under natural restrictions on agents preferences which accommodate switching costs status quo bias and other forms of inter temporal complementarity dynamically stable matchings exist we propose a new ordering of the stable set ensuring that it forms a lattice we investigate the robustness of dynamically stable matchings with respect to the market s time horizon and frequency of rematching opportunities

facilitating the transition to sustainable construction china s policies abstract china faces a challenge to balance its future urbanization process with resource conservation and environmental protection promoting sustainable construction is identified by the chinese government as an important strategy to tackle such challenges to promote sustainable construction the chinese government has released a large number of laws policies and regulations this paper investigates the policy system in china which aims to facilitate the transition to sustainable construction the related laws policies and regulations are analyzed and three main functions are identified namely regulation and control economic incentives and supporting activities the results show that the behaviours of various participants in the construction industry including the government developers builders suppliers and designers are regulated and controlled by these laws and regulations subsidy policies award policies and economic innovation policies are adopted by the government to promote renewable energy applications in buildings and infrastructure construction the key supporting activities for sustainable construction include strengthening technology innovation improving standards and evaluation establishing demonstration projects and publicity two emerging challenges of the current policy system are also identified they are a lack of considering social and economic dimensions of sustainable construction and the ineffectiveness of some key policies such as the environmental impact assessment policy this paper provides a useful reference for construction corporations and policy makers in china to facilitate sustainable construction in future urbanization process similarly policy makers in other emerging economies can understand how sustainable construction is promoted in china

how does germany s green energy policy affect electricity market volatility an application of conditional autoregressive range models abstract based on a dynamic model for the high low range of electricity prices this article analyses the effects of germany s green energy policy on the volatility of the electricity market using european energy exchange data from 2000 to 2015 we find rather high volatility in the years 2000 2009 but also that the weekly price range has significantly declined in the period following the year 2009 this period is characterised by active regulation under the energy industry law enwg the eu emissions trading directive etd and the renewable energy law eeg in contrast to the preceding period price jumps are smaller and less frequent especially for day time hours implying that current policy measures are effective in promoting renewable energies while simultaneously upholding electricity market stability this is because the regulations strive towards a more and more flexible and market oriented structure which allows better integration of renewable energies and supports an efficient alignment of renewable electricity supply with demand

analysis of existing building energy saving policies in japan and china building sector accounts for a large percentage of the total national energy consumption in most of the countries thus it is critical to formulate and implement appropriate energy saving policies in the building sector this paper focuses on energy saving policies in the building sector by conducting a comparative study between japan and china the exiting building energy saving bes policies actual effectiveness of policy implementation and obstacles to the effective policy implementation are compared in sequence related policies are categorized into four groups control and regulatory instruments economic market based instruments fiscal instruments and information and voluntary actions policy effect analysis identifies that bes policies have promoted building energy saving in both japan and china obstacles comparison reveals that japan and china shared many obstacles including high transaction costs and lack of applicable methodology compared with japan china is suffering more obstacles such as inefficient enforcement insufficient levels of information and awareness and immature financial regulation system based on the previous findings common suggestions for overcoming these obstacles of bes policies in japan and china are presented such as the accurate methods of baseline identification and emission accountings innovative incentives and more capacity building activities distinct suggestions for japan and china are also added by considering their own situations so that both countries can further improve their bes policies

3 d sustainability an approach for priority setting in situation of conflicting interests towards a sustainable development abstract this paper aims to provide a new approach to objectively assess hierarchies and priority setting in the relationship between environmental social and economic sustainability within sustainable development after a literature review several widely used conceptual figures diagrams describing this relationship were assessed using swot analyses in order to identify the major weaknesses in these pictorial descriptions based on the findings a new concept called 3 d sustainability has been developed and is presented visually as well as is described in the text this concept introduces and ranks criteria for the assessment of hierarchies within and conflicts of interests between social environmental and economic sustainability the three dimensions of sustainability these criteria are applied to several existing hierarchies and solutions to conflicts of interests based on the swot analyses the main shortcomings of the widely used conceptual figures were identified as 1 misinterpretation of embeddings 2 misjudgement of equity between the three dimensions of sustainability 3 a lack of expression of limitations and 4 lack of adequate decision support these shortcomings are overcome theoretically and in practice by 3 d sustainability a slightly more complex but conceptually richer figure than the widely used conceptual figures assessed in particular the shift of the burden of proof within the three sustainability dimensions is argued as a main solution the application of the criteria of 3 d sustainability to several real examples indicates its usefulness in decision support while justifying more sustainable hierarchies and solutions in the settlement of conflicts of interests within the three sustainability dimensions

energy performance of dwelling stock in iceland system dynamics approach abstract despite the significant energy use in dwellings buildings have the highest energy savings potential among all sectors one of the main analytical challenges is how to capture the impact from inertia driven by the current dwelling stock thus a dwelling stock model was established to study the impacts of physical processes e g aging as well as the effect of social processes e g household energy conservation behaviors on energy demand for space heating in the icelandic dwelling stock the model is initialized in the year 2000 and then calibrated with datasets on the icelandic dwelling stock and hot water consumption for residential space heating analysis of the base scenario confirms that the improvement in the average energy intensity of total dwelling stock with regular turnover of the dwelling stock is insignificant and gradual which relates to the inertia of the existing stock the comparison of the results from two policy scenarios with the base case illustrates that the aggressive demolition is more effective compared to the aggressive construction in reducing the total energy demand for space heating the results of this analysis can support policy makers by providing insights regarding the potential impact of building energy efficiency policies ensuring an effective policy package

technological progress and sustainable development what about the rebound effect abstract sustainability concepts that rest on the idea of resource or energy efficiency improvements due to technological progress tend to overestimate the potential saving effects because they frequently ignore the behavioral responses evoked by technological improvements efficiency improvements also affect the demand for resources and energy and often an increase in efficiency by 1 will cause a reduction in resource use that is far below 1 or sometimes it can even cause an increase in resource use this phenomenon is commonly labeled the rebound effect which is well known among energy economists but never attracted much attention in ecological economics the paper starts with the traditional neoclassical analysis of the rebound effect in a partial equilibrium framework that concentrates on the demand of one particular energy service such as mobility or room temperature it also provides an overview of some of the main empirical studies based on this model that mostly confirm the existence of the rebound effect but are controversial about its actual importance however we have to go beyond the neoclassical single service model in order to take care of the variety of possible feedback affecting energy use the paper presents two important expansions of the single service model in order to show the potential relevance of the rebound effect to ecological economics first it is shown that in a multi services model it proves to be difficult to make general statements about the relevance of the rebound effect in this case the overall effect of an increase in energy efficiency on total energy use depends on the on the assumptions about the substitutability between the services considered and the direction of the income effect second the paper also tries to take care of the fact that changes in resource use or energy use are frequently just side effects of other forms of technological progress especially technological change of a time saving nature can have a large influence on energy use as many time saving devices for example faster modes of transport require an increase in energy consumption that is frequently reinforced by a rebound effect with respect to time this effect will be especially strong when wages are high and at the same time energy prices are low as is currently the case in most industrialized countries consequently the paper also provides a strong argument for the introduction of energy taxes

residential energy consumption in urban china a decomposition analysis abstract residential energy consumption rec is the second largest energy use category 10 in china and urban residents account for 63 of the rec understanding the underlying drivers of variations of urban rec thus helps to identify challenges and opportunities and provide advices for future policy measures this paper applies the lmdi method to a decomposition of china s urban rec during the period of 1998 2007 at disaggregated product activity level using data collected from a wide range of sources our results have shown an extensive structure change towards a more energy intensive household consumption structure as well as an intensive structure change towards high quality and cleaner energy such as electricity oil and natural gas which reflects a changing lifestyle and consumption mode in pursuit of a higher level of comfort convenience and environmental protection we have also found that china s price reforms in the energy sector have contributed to a reduction of rec while scale factors including increased urban population and income levels have played a key role in the rapid growth of rec we suggest that further deregulation in energy prices and regulatory as well as voluntary energy efficiency and conservation policies in the residential sector should be promoted

voluntary emission trading potential of turkey abstract climate change is likely to cause serious market failures and carbon trading as a market instrument can help correct its negative impacts the global carbon markets established to combat climate change include regulatory and voluntary markets turkey cannot utilise regulatory carbon markets under the kyoto protocol as a result of her unique position in the unfccc some offsetting projects in turkey have benefitted only voluntary emission trading for the reduction of ghg emissions due to on going climate change negotiation under the unfccc it seems that turkey will not use the current regulatory carbon markets thus turkey should promote the use of and participation in voluntary carbon markets in this article emission reduction potential via energy efficiency renewable energy and solid waste management and corresponding offsetting of credits with their estimated prices is investigated for the period between 2013 and 2020 the emission reduction potential for energy efficiency renewable energy and solid waste management projects are estimated at 403 312 and 356 million tons of co 2 equivalent emissions respectively totalling 1 071 million tons of co 2 equivalent the total revenue of the carbon certificates are estimated in the range of 19 775 33 386 million us dollars for the same period

polices for increasing energy efficiency thirty years of experience in oecd countries energy efficiency improvement was an important phenomenon in the global energy balance over the past 30 years without energy efficiency improvements the oecd nations would have used approximately 49 more energy than was actually consumed as of 1998 this paper first reviews energy intensity trends for the major oecd nations since 1973 considering how much of the overall reduction in e gdp was due to energy efficiency improvement and how much was due to structural change the bulk of the paper examines the energy efficiency policies and programs adopted in japan united states and western europe commenting on their effectiveness and energy savings impacts where possible the paper also reviews the energy efficiency policies and programs adopted in california this experience shows that well designed policies can result in substantial energy savings as demonstrated in the united states where nine specific policies and programs reduced primary energy use in 2002 by approximately 11 substantial energy savings also occurred in japan some european countries and in the electricity sector in california

prices technology development and the rebound effect abstract energy efficiency is the critical parameter for policies that aim at reducing energy consumption while maintaining or even boosting economic growth the two main options to influence energy efficiency are changes in relative prices i e raising the price of energy through economic instruments or to introduce new technologies which increase the productivity of each unit of energy this paper is based on the notion that in an equilibrium economy the marginal economic productivity is identical for all factors i e energy labour knowledge and capital from this premise two main conclusions can be drawn first any change in price or technology will have an impact on the whole economy by creating feedbacks through the substitution of factors of production and goods as well as increased wealth second the two policy approaches changing relative prices and technology development are not opposite to each other they are the two faces of the same reality and should be developed and promoted simultaneously and consistently

sequential auctions of interdependent objects israeli cable television licenses in israel area cable television catv licenses were auctioned sequentially this paper provides evidence that i there were interdependencies among many of the franchises and that ii subscriber fees for the interdependent franchises decreased over time in this auction

sequential second price auctions with private budgets abstract we study an auction game in which two units of a good are sold via two second price auctions sequentially to three or more bidders who have private budgets that limit their spending in the auctions we characterize the unique symmetric equilibrium in equilibrium while bidders bid the minimum of their valuations and budgets in the second auction their aggression in the first round depends on two factors the competition from other bidders as measured by the probability of facing high budget bidders and the option value from participating the second auction as measured by the budget difference between various bidders the former factor makes bidders more aggressive and the latter makes them less aggressive in particular when the competition factor dominates the sequential auctions generate higher revenue in expectation than the uniform price auction

matching with contracts we develop a model of matching with contracts which incorporates as special cases the college admissions problem the kelso crawford labor market matching model and ascending package auctions we introduce a new law of aggregate demand for the case of discrete heterogeneous workers and show that when workers are substitutes this law is satisfied by profit maximizing firms when workers are substitutes and the law is satisfied truthful reporting is a dominant strategy for workers in a worker offering auction matching algorithm we also parameterize a large class of preferences satisfying the two conditions

carbon dioxide co2 emissions during urbanization a comparative study between china and japan as the world s largest emitter of co2 china is facing increasing domestic and international pressures on emissions mitigation considering japan s leading position in energy conservation this paper conducts a comparative study between china and japan at the urbanization stages to analyze the similarities as well as differences of influencing factors of co2 emissions results indicate that although co2 emissions in japan and china showed the similar characteristics of rigid growth during the urbanization processes significant differences exist in factors such as co2 emissions per capita energy structure and energy intensity between the two countries which are the determinants for co2 emissions growth a cointegration model is constructed to examine the long run equilibrium relationship between co2 emissions and factors including gdp urbanization level energy intensity and cement manufacture empirical results show that there is a quadratic relationship between income growth and co2 emissions granger causality test is then adopted to explore the causal relationships among the variables the future co2 emissions and emission reduction potentials in china are estimated based on scenario analysis finally japan s valuable experience of reducing energy intensity and optimizing energy structure is concluded to provide important policy implications for china s strategic low carbon planning and low carbon transition

bottom fishing and declining prices in sequential auctions abstract we study standard sequential auctions in which the seller chooses the order of sale and right to choose auctions in which the winner chooses her preferred item from the remaining items empirically prices in sequential auctions tend to decline and sellers often hold right to choose auctions in our setting the right to choose format guarantees declining prices and efficiency in the standard auction a buyer may submit a low bid for the first item bottom fishing despite its being her less preferred item an example shows that the standard auction has declining prices is inefficient and gives lower expected revenue than the right to choose journal of economic literature classification numbers d44 d82

perspectives on implementing energy efficiency in existing swedish detached houses in this study we first analyse energy efficiency measures in existing electrically heated houses in sweden from a societal economic perspective measures to a house envelopes and to energy supply chains are evaluated through a system analysis approach and we include the external costs of climate change and the effect of different swedish climatic zones we find that in a typical house from the 1970s conversion from electric heating is highly motivated since the mitigation cost of conversion is lower than the estimated external costs of emitted co2 both conversions and house envelope measures are more motivated in the northern part of the country where there is a higher heat demand a successful implementation of changes requires them to be attractive for consumers to adopt we therefore secondly analyse the economic conditions for swedish house owners to implement societal economic cost efficient measures we include the economic influence of an investment subsidy for heating system conversion an income tax deduction for changing windows customer electricity tax real estate tax and of the cost of purchased energy from different energy suppliers apart from the economics several other factors affect a house owner s decision to change heating systems we therefore thirdly analyse house owners perceptions of different heating supply alternatives based on the results of two comprehensive questionnaires these different perspectives are combined in a discussion whether the studied policy instruments encourage house owners to implement changes in accordance with the energy efficiency goals of decision makers we find that the investment subsidy could be useful to break the lock in effect of resistance heaters which house owners seemed to experience the electricity tax makes heating systems in line with national goals more competitive and efficiency measures to the house envelope more profitable the reduction of the electricity tax in the northern part of the country has the opposite effect also the increase in real estate tax when implementing energy efficiency measures gives a contradictory message the price differences between energy suppliers has a larger impact on the house owners economic conditions than both subsidies and tax rate changes and possibly also affect the house owner s attitudes towards various systems

risk aversion and the choice between risky prospects the preservation of comparative statics results most results in what can be termed the comparative statics of risk aversion are obtained when there is only one source of uncertainty the primary example which originally motivated the definition of risk aversion is that more risk averse people are willing to pay a higher premium for insuring against risk it is known that the results do not generally carry over when there is another source of uncertainty the paper develops conditions under which comparative statics results are robust against the introduction of additional sources of uncertainty

sequential auctions of stochastically equivalent objects abstract we show that in sequential auctions of a large enough number of stochastically equivalent objects with bounded values prices will on average have a downwards trend

searching for sustainability the poverty of spontaneous order abstract traditional approaches to sustainability rely on models that depend upon judgments of welfare across future generations right prices and some sense as to what future persons will find giving of utility these models both accept the spontaneous order of market processes and rely on that order to derive optimal consumption paths into the future sustainability is however not a problem of divining optimal paths predicated upon right prices rather sustainability to be operational requires a prior constructed order predicated upon rights for future persons and duties for those now living who sit in a position as dictator over the settings and circumstances that will be passed on to future persons rights based approaches to sustainability do not rely upon unknowable preferences of future persons but rather upon an environmental regency in which those now living agree to preserve settings and circumstances for the future this reminds us that the issue of sustainability concerns not how much to preserve but what to preserve

the strategy structure of two sided matching markets we study two sided markets in which agents are buyers and sellers or firms and workers or men and women the agents are to form partnerships which provide them with satisfaction and at the same time make monetary transfers e g salaries or dowries the core of this market game is shown to have a particularly nice structure so that precise answers can be given to questions concerning comparative statics and manipulability the idea of using walrasian equilibrium as a mechanism for making allocations with desirable properties of fairness and efficiency has been studied extensively the scheme involves having agents specify their supply and demand functions the competitive equilibria are then calculated and allocations are made accordingly in general this procedure may run into two difficulties first nonuniqueness if there are several equilibria there may be no fair way to decide which one should be implemented and second manipulability if there is only one equilibrium an informed agent may be able to influence it by suitably falsifying his demand data however as we will show here using the walrasian mechanism does work remarkably well for a certain class of important markets these are the matching markets of our title and they include markets for single items like houses where it is assumed that traders do not wish to acquire more than one item they also include labor markets in which it is desired to match workers with jobs at suitable salaries academic markets in which students are to be assigned to educational institutions marriage markets where men and women are matched through negotiating of dowries it turns out that in these markets both the problems of nonuniqueness and manipulability can be resolved in a

how carbon offsetting scheme impacts the duopoly output in production and abatement analysis in the context of carbon cap and trade abstract in the context of addressing climate change the carbon emission trading scheme has become one of the main measures adopted by many countries and regions to achieve emission reduction goals noticing this current lack of research based on a duopoly model this paper quantitatively explores the impact of carbon offsetting scheme on both emission trading participants profits and industry s output by drawing on advanced experience of carbon offsetting scheme from developed countries such as us switzerland and eu and thus provides a perspective for government to design optimal aggregate standard for carbon cap and trade results show a negative correlation between enterprises carbon intensity and their equilibrium output in the product market and indicate a threshold for the relative magnitude of the duopoly enterprises carbon intensity above which their absolute output will differ dramatically the incorporation of carbon offsetting scheme into a non offset quota trading scheme will reduce its equilibrium carbon price thereby mitigate its negative impact on industry s total output in the product market by an either linear or quadratic form depending on the design for the proportion ceiling of offsetting quota

sustaining the emerging carbon trading industry development a business ecosystem approach of carbon traders abstract this paper explores how carbon traders nurture the business ecosystem to sustain the emerging carbon trading industry development we collected primary data from a multinational carbon trader and its ecosystem partners in china through the construction of interviews and documentary the research findings show the carbon trading industry has experienced four stage evolution with different driving forces the carbon trader attracted and organized ecosystem partners to facilitate the cdm project owners to create carbon credits and trade them a systematic business ecosystems approach through the lens of context cooperation and configuration initiated by carbon traders has facilitated the industry development our findings also implicate to industrial practitioners and policymakers for sustaining the emerging industry development at both the current and the post kyoto protocol periods

sustainable growth criteria minimum benchmarks and scenarios for employment and the environment abstract the relationship of economic growth and environmental impact has spurred fierce debates between growth optimists referring to the phenomenon of the environmental kuznets curve and pessimists referring to the limits to growth however no operational set of simple criteria has been developed so far to assess the sustainability of a given growth pattern this is all the more true for measures combining environmental and social criteria the paper undertakes to sketch out such criteria and to assess them by applying them to transdiciplinary sustainability scenarios and model simulations with panta rhei one of the most complex models of the german economy theoretical considerations as well as the empirical work with the model demonstrate that there are indeed trade offs between economic growth and environmental impacts and a positive correlation of growth and employment nonetheless it is still possible to develop carefully orchestrated strategies that combine economic competitiveness low unemployment rates and an easing of the pressure on the environment social and technical innovation reduced working time a modernised social security system green taxes and salary increases proportional to labour productivity growth are essential parts of any such strategy the triple effectiveness of such strategies regarding environmental social and economic sustainability is demonstrated by the model runs

bidding with securities auctions and security design we study security bid auctions in which bidders compete for an asset by bidding with securities that is they offer payments that are contingent on the realized value of the asset being sold the value depends on investment by the winner thus creating the possibility of moral hazard such auctions are commonly used both formally and informally in formal auctions the seller generally restricts bids to an ordered set such as an equity share or royalty rate by restricting the bids standard auction formats such as first and second price auctions can be used in informal settings with competing buyers the seller does not commit to a mechanism upfront rather bidders offer securities and the seller chooses the most attractive bid based on his beliefs ex post we characterize equilibrium payoffs and bidding strategies in this setting and show that an informal mechanism yields the lowest possible revenues across all mechanisms we also determine the optimal formal mechanism and show that the security design is more important than the auction format we show that the revenue equivalence principle that expected revenues are independent of the auction format holds if the set of permissible securities is ordered and convex such as equity otherwise it need not hold for example when bidders offer standard debt securities a second price auction is superior on the other hand if bidders compete on the conversion ratio of convertible debt a first price auction yields higher revenues finally we examine how different forms of moral hazard impact our results

monotone comparative statics under uncertainty this paper analyzes monotone comparative statics predictions in several classes of stochastic optimization problems the main results characterize necessary and sufficient conditions for comparative statics predictions to hold based on properties of primitive functions that is utility functions and probability distributions the results apply when the primitives satisfy one of the following two properties i a single crossing property which arises in applications such as portfolio investment problems and auctions or ii log supermodularity which arises in the analysis of demand functions affiliated random variables stochastic orders and orders over risk aversion

modelling decisions on energy efficient renovations a review the buildings sector accounts for more than 30 of global greenhouse gas emissions despite the well known economic viability of many energy efficient renovation measures which offer great potential for reducing greenhouse gas emissions and meeting climate protection targets there is a relatively low level of implementation we performed a citation network analysis in order to identify papers at the research front and intellectual base on energy efficient renovation in four areas technical options understanding decisions incentive instruments and models and simulation the literature was reviewed in order to understand what is needed to sufficiently increase the number of domestic energy efficient renovations and to identify potential research gaps our findings show that the literature on energy efficient renovation gained considerable momentum in the last decade but lacks a deep understanding of the uncertainties surrounding economic aspects and non economic factors driving renovation decisions of homeowners the analysis indicates that the socio economic energy saving potential and profitability of energy efficient renovation measures is lower than generally expected it is suggested that this can be accounted for by the failure to understand and consider the underpinning influences of energy consuming behaviour in calculations homeowners decisions to renovate are shaped by an alliance of economic and non economic goals therefore existing incentives typically targeting the economic viability of measures have brought little success a deeper understanding of the decisions of homeowners is needed and we suggest that a simulation model which maps the decision making processes of homeowners may result in refining existing instruments or developing new innovative mechanisms to tackle the situation

new directions for household energy efficiency evidence from the uk the market rarely delivers energy efficiency improvements spontaneously as there is no market push consumers are not providing a pull towards energy efficiency usually because they are ignorant of or indifferent to the range on the market or the energy implications of their purchases whilst consumers are concerned about climate change and generally understand the causal role of fossil fuels they believe either that they have done everything or that one person cannot make a difference without a positive design focus from manufacturers or a clear demand from consumers no part of the market will deliver energy efficiency naturally policy has to provide the drive within the uk the opportunities to introduce policies based on higher energy prices are constrained by the impact these have on low income households this means that product policy market transformation has to be the main delivery mechanism for domestic energy efficiency in the uk the policies adopted so far in the uk and eu have been successful with existing products but have not prevented the development of new profligate equipment this limited success demonstrates the need for european policy to be more forceful and for policy to involve engagement with manufacturers about the products they are planning to introduce to motivate consumers policy should focus on carbon and incorporate feedback without these developments and considerably more activity by the european commission and member states energy efficiency will not contribute its potential to the uk target of 60 reduction in carbon dioxide emissions by 2050

scenario analysis of energy saving and co2 emissions reduction potentials to ratchet up japanese mitigation target in 2030 in the residential sector abstract this paper assesses to what extent co 2 emissions from electricity in the residential sector can be further reduced in japan beyond its post 2020 mitigation target known as intended nationally determined contribution indc the paper examines the reduction potential of electricity demand and co 2 emissions in the residential sector by conducting a scenario analysis electricity consumption scenarios are set up using a time series regression model and used to forecast the electricity consumption patterns to 2030 the scenario analysis also includes scenarios that reduce electricity consumption through enhanced energy efficiency and energy saving measures the obtained results show that japan can reduce electricity consumption and co 2 emissions in the residential sector in 2030 more than the japanese post 2020 mitigation target indicates at the maximum the electricity consumption could be reduced by 35 twh which contributes to 55 4 mtco 2 of emissions reduction in 2030 compared to 2013 if the voluntarily targeted co 2 intensity of electricity is achieved the result implies that japan has the potential to ratchet up post 2020 mitigation targets discussed under the paris agreement of the united nations framework convention on climate change unfccc

ends in view the capabilities approach in ecological sustainability economics while traditional scientific endeavor seeks to avoid the problem ecological economics and the broader emergent field of sustainability economics e se are explicitly grounded in a particular ethico moral assertion one that defines sustainability as a normative notion about the way how humans should act towards nature and how they are responsible towards one another and future generations baumgartner and quaas 2010 p 445 thus e se is neither a purely positive science nor is it a purely normative endeavor but it is what has been called relevant science baumgartner and quaas 2010 p 447 a key objective of e se is therefore said to be to study how ecosystems and human activity interrelate in terms that extend beyond functional and descriptive analysis of this interrelationship and towards explicitly incorporating this normative vision the result that is aimed for is a discipline that is constituted as the best possible approach to the science and management of sustainability

sequential auctions of endogenously valued objects two completely informed but possibly asymmetric bidders buy or sell identical claims in sequential auctions they subsequently receive monetary prizes that depend upon the final allocation of claims iterated elimination of weakly dominated strategies leaves a unique nash equilibrium for any prize schedule prices weakly decline as the auctions progress and points of strict decline have a simple characterization for one class of prize schedules which arises naturally if duopolists bid for a scarce input the equilibrium is completely characterized many initial allocations generate the same final unequal division of claims which may be interpreted as the natural market structure journal of economic literature classification numbers d43 d44 l11

high bids and broke winners abstract this paper analyzes auctions where budget constrained bidders have options to declare bankruptcy it predicts a bidding equilibrium that changes discontinuously in a borrowing rate available to bidders when the borrowing rate is above a threshold high budget bidders win and the likelihood of bankruptcy is low when the borrowing rate is below the threshold the winner is the most budget constrained bidder and is most likely to declare bankruptcy this result explains the high bids and broke winners anomaly in the c block fcc spectrum auction based on its equilibrium analysis the paper proves that a seller can profit from offering to finance the highest bidder at a below market interest rate even with default risk journal of economic literature classification numbers d44 d45 d82 g33 l96

the declining price anomaly in dutch dutch rose auctions in symmetric independent private value auctions of a single object with risk neutral bidders the english second price auction has strategic simplicity it is optimal for bidders to reveal their valuation of the object and make bids accordingly in that case the auction is won by the person with the highest valuation who pays a price equal to the second highest valuation in a dutch first price auction this simplicity vanishes here winning bidders have to pay their bid to make a profit they shade their bids and bid below their valuation of the object somewhat loosely one may state that an english auction is truth revealing whereas a dutch auction requires strategic behavior the simple structure of the one unit english auction vanishes if two identical objects are auctioned sequentially now in the first round it is optimal for bidders to shade their bids to account for the option value of participating in the subsequent second round robert j weber 1983 bidders with a higher valuation also have a higher option value therefore they shade their bids in the first round by a greater amount than do bidders with a lower valuation as the auction proceeds the number of bidders decreases over the sequence of auctions the number of objects decreases as well the first fact has a negative effect on the competition for an object and the second has a positive effect both effects cancel out and prices follow a martingale as a result all gains to waiting are arbitraged away and the expected prices in both rounds are the same the latter result also holds for sequential auctions of more than two objects and does not depend on whether the auction is english or dutch this neat theoretical result is not supported by empirical research which usually finds price declines orley ashenfelter 1989 found a mild price decrease in sequential auctions of identical units of wine mcafee and daniel vincent 1993 also present empirical evidence on sequential wine auctions they found that on average the second unit of wine was sold at a price 1 4 percent lower than the price of the first unit victor ginsburgh 1998 uses data from wine auctions in which the auctioneer acted as an agent for bidders who were not present at the auction he found price declines but apparently the absent bidders entered bids that did not fit with the theory empirical studies by ashenfelter and david genesove 1992 see also jean jacques laffont 1997 and alan beggs and kathryn graddy 1997 concern heterogeneous objects they also detected price declines because of the contradiction between theory and empirical studies the declining price phenomenon is regarded to be an anomaly

carbon trading current schemes and future developments abstract this paper looks at the greenhouse gas ghg emissions trading schemes and examines the prospects of carbon trading the first part of the paper gives an overview of several mandatory ghg trading schemes around the world the second part focuses on the future trends in carbon trading it argues that the emergence of new schemes a gradual enlargement of the current ones and willingness to link existing and planned schemes seem to point towards geographical temporal and sectoral expansion of emissions trading however such expansion would need to overcome some considerable technical and non technical obstacles linking of the current and emerging trading schemes requires not only considerable technical fixes and harmonisation of different trading systems but also necessitates clear regulatory and policy signals continuing political support and a more stable economic environment currently the latter factors are missing the global economic turmoil and its repercussions for the carbon market a lack of the international deal on climate change defining the post kyoto commitments and unfavourable policy shifts in some countries cast serious doubts on the expansion of emissions trading and indicate that carbon trading enters an uncertain period

precautionary bidding in auctions we analyze bidding behavior in auctions when risk averse buyers bid for a good whose value is risky we show that when the risk in the valuations increases dara bidders will reduce their bids by more than the appropriate increase in the risk premium ceteris paribus buyers will be better off bidding for a more risky object in first price second price and english auctions with affiliated common interdependent values this precautionary bidding effect arises because the expected marginal utility of income increases with risk so buyers are reluctant to bid so highly we also show that precautionary bidding behavior can make dara bidders prefer bidding in a common values setting to bidding in a private values one when risk neutral or cara bidders would be indifferent thus the potential for a winner s curse can be a blessing for rational dara bidders

empirics on the long run effects of building energy codes in the housing market we study the effectiveness of building energy codes taking a long run perspective the focus is on regulation s impact on energy demand in both high and low quality residences in other words the diffusion and the entry of green buildings in the housing market we develop a measure for regulation intensity and apply this to a panel error correction regression model for energy requirements of a large sample of german apartment houses built between 1950 and 2005 we show that regulation is effective in saving energy in particular regulation pushes investors in the low quality housing market segment toward the technological frontier indirectly it also affects the high quality segment jel q41 r52

the impacts of energy prices on energy intensity evidence from china in this paper we present a review of the deregulation of energy prices in china between 1985 and 2004 and assess the impacts of changes in energy prices on aggregate energy intensity and coal oil electricity intensity we used time series data to provide estimates of energy price elasticities empirical results showed that 1 the own price elasticities of coal oil and aggregate energy were negative in periods both before and after 1995 implying that higher relative prices of different energy types lead to the decrease in coal oil and aggregate energy intensities however the positive own price elasticity of electricity after 1995 probably indicates that the price effect was weaker than other factors such as income effect and population effect 2 the impacts of energy prices were asymmetric over time 3 sectoral adjustment also drove the decrease in aggregate energy intensity although raising energy prices to boost efficiency of energy use seems to be an effective policy tool other policy implications concerned with energy prices such as energy supply security and fuel poverty must also be considered
