a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

european schemes for promoting renewables in liberalised markets abstract the paper describes possibilities and problems for penetration of supply systems based on renewable energy sources in liberalised markets the analysis is based on recent development in eu with different models for support of installations based on renewable energy these include feed in models with guaranteed minimum tariffs tender models for different bands of technologies and green certificates trading models with obligatory consumer quota the paper describes the market situation in selected european countries including germany the uk holland and denmark an eu directive from september 2001 has postponed the decision on a possible harmonisation of promotional models until at least 2005 in order to obtain more practical experience with the different support schemes a critical evaluation is given in this paper of the different models with proposals for a balanced development between environmental and trading concerns it is argued that too much emphasis is presently given to the side of free trade at the expense of long range planning for a sustainable energy development

progress along the path evolving issues in the measurement of genuine saving more than 10 years since a practical linkage between sustainable development and a measure of national wealth expanded to include natural and environmental resources was first posited the empirical estimation of adjusted net savings dubbed genuine saving has evolved considerably in this paper we take stock of both progress achieved and the challenges that remain we begin by recalling the key points made in pearce and atkinson 1993 ecol econ 8 103 which presented the first cross country estimates of savings rates adjusted to reflect depletion and degradation of the environment we then briefly summarise the evolution of the theoretical argument linking savings and sustainability however the main focus of this paper is an aspect that concerned david pearce greatly namely the evolution of the measurement of genuine savings we identify and consider the empirical evidence with regard to two particular measurement issues the valuation of exhaustible resources and environmental degradation common to the both issues are concerns about measuring changes in national wealth in real world economies

an experimental validation of hypothetical wtp for a recyclable product using a within subject experiment we compare hypothetical andreal willingness to pay wtp for an improvement in therecyclability of a product subjects are faced with a real paymentscenario after they have responded to a hypothetical question contrary to most of the results obtained in similar studies at apopulation level there are no significant median differencesbetween actual and hypothetical stated values of wtp however within subject comparisons between hypothetical and actual valuesindicate that subjects stating a low high hypothetical wtp tendto underestimate overestimate the value of their actualcontributions

testing genuine savings as a forward looking indicator of future well being over the very long run genuine savings gs have been much used in recent years as an indicator of a country s sustainability according to some theorists e g arrow et al 2012 under certain conditions a country with a positive level of gs should experience non declining future utility given the assumption of unlimited substitutability among all forms of capital sometimes called weak sustainability this paper reports the first very long run tests of gs also called comprehensive investment or adjusted net savings as a forward looking indicator of future well being we assemble data for british capital back to 1765 and construct several net investment measures which are used as indicators of two alternative measures of future well being consumption per capita and real wages an allowance for a value of time due to exogenous technological progress is included in some gs measures and we demonstrate the importance of this measure and the choice of discount rate over the very long run on the whole our results do not reject the postulated relationship between gs and future well being and show gs can be a forward looking indicator of future well being for periods of up to 100 years

induced value tests of the referendum voting mechanism abstract an induced value laboratory experiment is conducted testing the incentive compatibility of the referendum voting mechanism for eliciting willingness to pay for public goods although errors were observed at the individual level aggregate results suggest incentive compatibility in both hypothetical and real referenda

status effects and environmental externalities abstract this paper examines a static competitive economy where the production of a consumption good generates pollution that adversely affects human welfare preferences are defined over consumption leisure pollution and economic status each person s status increases with her own consumption but decreases with the average consumption of society the achievement of a pareto efficient resource allocation requires a consumption tax to offset the incentive to overconsume in the pursuit of enhanced status in contrast with standard prescriptions the efficient pollution tax generally exceeds the sum of individuals marginal willingness to pay for pollution abatement these findings remain unaltered when preferences are modified to incorporate altruistic concern for others well being altruism however suggests a potential role for government intervention to achieve a desirable i e pareto efficient distribution of welfare between individuals

historical wealth accounts for britain progress and puzzles in measuring the sustainability of economic growth we thank the leverhulme trust for funding this research under the project history and the future

valuation of landmass degradation using fuzzy hedonic method a case study of national capital region a hedonic model to determine the revealed willingness to pay for landmass of different suitability classes based on landmass functional characteristics obtained through subjective assessments is developed for the national capital region in india the inherent non specificity involved in subjective evaluation is minimized using fuzzy logic based regression technique the proposed fuzzy regression involves regression using central values of triangular fuzzy number and minimization of non specificity using linear programming the revealed willingness to pay for landmass of different suitability classes is used for valuation of disbenefits due to urban expansion on landmass of different agricultural suitability classes in national capital territory of delhi appropriate pricing policies to prevent the future inappropriate landuse practices are developed using the landmass valuation

money income prices and interest rates including data from the 1980s sharply weakens the postwar time series evidence indicating significant relationships between money however defined and nominal income or between money and either real income or prices separately focusing on data from 1970 onward destroys this evidence altogether evidence indicating cointegration of real income and real money balances with due allowance for the effect of interest rates also deteriorates when the sample extends through the 1980s a positive finding is that the spread between the commercial paper rate and the treasury bill rate consistently contains highly significant information about future movements in real income copyright 1992 by american economic association

do reminders of substitutes and budget constraints influence contingent valuation estimates a test is performed of the recommendation by the noaa panel on contingent valuation that respondents be reminded about other substitute resources and their budget constraint prior to answering the willingness to pay wtp question the context for this experiment is a cvm study of the benefits from reducing fire hazards to old growth forests in oregon the test was performed using two mail surveys that were otherwise identical except for the inclusion of reminder statements prior to the wtp question the dichotomous choice logit equations were not statistically different between versions and the mean wtp results were identical

flight to quality in banking and economic activity abstract recent explanations of the transmission mechanism of monetary policy have emphasized that riskier lower net worth borrowers are more dependent on bank lending than larger less risky borrowers evidence from the federal reserve s survey on terms of bank lending indicates that the proportion of relatively high quality new loans safe moves countercyclically and granger causes gdp and inventory investment in the aftermath of a tightening of monetary policy the safe variable increases and in turn policy tends to relax once safe has risen

analysis of genuine saving and potential green net national income portugal 1990 2005 abstract the context of this paper is the measurement of welfare and weak sustainability defined as non declining utility in dynamic economies i e comprehensive or green accounting we estimate green net national income gnni and genuine saving gs for portugal for the years 1990 to 2005 accounting for the disamenity of air pollution emissions the depreciation of commercial forests and the value of time discussing the implications of the assumptions underlying the inclusion of these terms in the green accounting model the influence of short run cycles is analyzed by estimating gnni excluding business cycles our results suggest that business cycles affect the sustainability message of gnni we find that potential gnni is growing and gs is positive in the analyzed period thereby not indicating a weak sustainability problem in portugal although both depict a trend towards unsustainability excluding technological progress there is a contradiction in the sustainability message of gnni and gs

a learning design for reducing hypothetical bias in the contingent valuation method over the last few years a great deal of research has focussed on hypothetical bias in value estimates obtained with the contingent valuation cv method and on means for ameliorating if not eliminating such bias to date efforts to eliminate hypothetical bias have relied on calibration techniques or on word smithing of one kind or another to induce subjects to provide responses to hypothetical questions that mimic responses made by subjects facing actual payments in the valuation experiment this paper introduces a different approach for eliminating hypothetical bias a design for a cv survey format is presented which provides subjects with the opportunity to learn how the cv institution works sequential referenda are conducted where respondents gain experience in cv settings by participating in both hypothetical and real referenda the logic of this learning design is a straightforward application of the trials process used in experimental economics we demonstrate that the learning design is effective in eliminating hypothetical bias in surveys concerning donations to two different public goods

sustainability and technical progress a rigorous model connects together the following three basic concepts 1 sustainability meaning the generalized future power of an economy to consume over time 2 green nnp meaning a current measure of national income that subtracts off from gnp not just depreciation of capital but also more generally depletion of environmental assets evaluated at current efficiency prices 3 technological progress meaning a projection onto the future of the so called solow residual a simple general formula is derived some crude calculations suggest a possibly strong effect of the residual which hints that our best present estimates of long term sustainability may be largely driven by predictions of future technological progress

willingness to pay for renewable energy primary and discretionary choice of british households for micro generation technologies this paper documents the policy context of renewable energy production in the european union the research adopts a choice experiment approach to investigate households wtp for these renewable energy technologies in the uk the micro generation technologies comprise solar photovoltaic micro wind solar thermal heat pumps and biomass boilers and pellet stoves the study compares the results from conditional and mixed logit models which estimate the distribution of utility coefficients and then derives wtp values as a ratio of the attribute coefficient to the price coefficient with a model in which the wtp distribution is estimated directly from utility in the money space the results suggest that whilst renewable energy adoption is significantly valued by households this value is not sufficiently large for the vast majority of households to cover the higher capital costs of micro generation energy technologies

in search for yield survey based evidence on bank risk taking abstract monetary policy can have an impact on economic and financial stability through the risk taking of banks falling interest rates might induce investment into risky activities this paper provides evidence on the link between monetary policy and bank risk taking we use a factor augmented vector autoregressive model favar for the us for the period 1997 2008 besides standard macroeconomic indicators we include factors summarizing information provided in the federal reserve s survey of terms of business lending stbl these data provide information on banks new loans as well as interest rates for different loan risk categories and different banking groups we identify a risk taking channel of monetary policy by distinguishing responses to monetary policy shocks across different types of banks and different loan risk categories following an expansionary monetary policy shock small domestic banks increase their exposure to risk large domestic banks do not change their risk exposure foreign banks take on more risk only in the mid 2000s when interest rates were too low for too long

renewable energy support mechanisms in the gulf cooperation council states analyzing the feasibility of feed in tariffs and auction mechanisms renewable energy will be a crucial ingredient in the transition to a more sustainable future the renewable energy sector requires a variety of financial support mechanisms in order to further consolidate and expand currently the most prominent renewable energy support mechanisms are feed in tariffs and renewable energy auctions although these mechanisms have been used and analyzed extensively in western countries and more recently economies in transition they have rarely been examined in the arab gulf region yet particularly the gulf cooperation council gcc states have undertaken important steps towards renewable energy adoption which could be greatly facilitated with the use of financial support mechanisms this paper analyzes the feasibility of feed in tariffs and renewable energy auctions adoption in gcc based on an extensive meta analysis of the literature on these two mechanisms in both developed and developing countries the paper identifies a set of conditions necessary for success and evaluates the presence of favorable these conditions in the gcc context our findings reveal that while conditions that would ensure political feasibility are largely absent for both types of mechanisms auctions could be a more successful strategy at the moment

air pollution and green accounts a simple model treating air emissions as cumulative pollutants is used to derive measures of green net national product the model implies that pollution emissions are properly valued at their marginal social costs in the measurement of green nnp the level of genuine savings net savings less the value of resource depletion and pollution emissions is shown to provide a useful indicator of sustainable development recent figures on the social costs of fuel cycles are used to derive genuine savings measures for the uk and other european nations several countries had negative genuine savings during the 1980s

bank competition and credit standards this article offers an explanation for the substantial variation of credit standards and price competition among banks over the business cycle as the economic outlook improves the average default probabilities of borrowers decline this affects the profitability of screening and causes bank screening intensity to display an inverse u shape as a function of economic prospects low screening activity in expansions creates intense price competition among lenders and loans are extended to lower quality borrowers as the economic outlook worsens price competition diminishes and credit standards tighten significantly deposit insurance may contribute to the countercyclical variation of credit standards copyright 2004 oxford university press

the dynamics of credit markets in a model with learning abstract a dynamic credit market is modeled in which the production and processing of information leads to alternating and persistent periods of growth and contraction in the model the number of projects engaged in determines the precision of estimates of future returns obtained from current investment shocks to underlying returns to risky projects are magnified and prolonged by the learning process multiple equilibria may exist and the magnification effect may be even larger since shocks can move the credit market to a new equilibrium the allocation of credit is generally not a constrained pareto efficient allocation

monetary policy and bank lending in the euro area is there a stock market channel or an interest rate channel abstract in this paper i compare a traditional demand oriented model of bank lending with its focus on short term interest rates in the money market to a non traditional capital budgeting model of bank lending based on movements in share valuations for the euro area using non nested hypothesis tests omitted variables tests and granger causality tests i reject the traditional demand oriented model of bank lending and fail to reject the capital budgeting model of bank lending for monetary financial institutions mfi s in the euro area even though europe is a bank based financial system it appears the stock market plays a key role in the lending decisions and allocation of resources in europe one possible policy implication of this research is that the central bank should try and stabilize stock prices in order to achieve their goal of stabilizing bank lending and the economy

well being and or quality of life in eu countries through a multidimensional index of sustainability abstract the aim of my paper is to demonstrate that sen s theory of well being can be applied to make the concept of sustainable human development operational through the building of a multidimensional index of sustainability which takes into account at the same time economic social and environmental variables this index may be considered an alternative to the current measures of welfare sustainability since not only conventional measures such as gdp but also multi attribute indices such as human development index hdi genuine savings index of sustainable economic welfare isew etc are found to be inadequate to make the concept of sustainable development operational therefore the limitations of these measures of welfare sustainability justify the search for a new index of sustainability this index will show at the operational level how sen s theory of well being can be useful to sustainable development it was applied to eu countries using the standardised deviation methodology being the closest and most suitable methodology to be adopted for building multidimensional indices the factor analysis methodology will also be used in my paper lastly the comparison between sen s trend of sustainability and gdp trend index number which are both of them applied to italy will show how much the criticisms and the limitations directed towards the indicator of gdp are founded

the role of technological progress in testing adjusted net savings evidence from oecd countries abstract in this paper we investigate the relationship between comprehensive measures of savings and changes in future consumption in oecd countries this relationship is at the basis of the interpretation of adjusted net savings as a weak sustainability indicator and so evidence of its validity provides support to the use of this indicator we construct various measures of comprehensive savings for 20 oecd countries to include depletion from non renewable resources human capital investment and technological progress given their importance especially for rich countries we focus on the role of technical progress and human capital in the form of changes in education level we do not find strong evidence in favor of including green adjustments in the conventional net savings however we find compelling evidence for the inclusion of technological progress since this involves a forward looking term the above result suggests that to construct an indicator of weak sustainability from conventional net savings some estimate of future technological progress is needed

the social cost of carbon and its policy implications the shadow price or social cost of carbon is an important indicator of the global incremental damage done by emitting greenhouse gases today cost benefit analysis would set the optimal amount of greenhouse gas emission reduction at the point where this social cost just equals the incremental cost of controlling emissions the higher the value for the social cost of carbon the more control is warranted this comparison assumes that cost benefit analysis is the correct way of determining climate change policy and many believe this is not the case because of the very long term irreversible and potentially catastrophic nature of global warming but in the short run at least a comparison of cost and benefits is required and in any event all decisions imply costs and benefits but what is the right figure for the social cost of carbon this paper reviews the uk government s assessment of the cost and concludes that it has been set far too high because of a misreading of the integrated assessment models used to balance costs and benefits moreover adoption of the uk government s shadow price would have formidable implications for energy policy in the uk and for policies on afforestation copyright 2003 oxford university press

does nnp growth indicate welfare improvement abstract we show that instantaneous increases in real nnp over time are an accurate indicator of true dynamic welfare improvements this highlights a connection between the theory of green or comprehensive national income accounting and the theory of real price indices

trade credit and the effect of macro financial shocks evidence from u s panel data using disaggregated panel data we examine how firms change trade credit in response to a monetary tightening we find that both accounts payable and accounts receivable increase with tighter monetary policy implying that trade credit helps firms absorb the effect of a credit contraction further both s p 500 firms and a comparison group of smaller firms increase net trade credit accounts receivable minus payable making up for the reduced liquidity associated with tighter policy however we find no evidence that large firms play this role more actively than smaller firms

how capital regulation and other factors drive the role of shadow banking in funding short term business credit abstract this paper empirically analyzes how capital regulation risk and other factors altered the relative use of shadow banking funded short term business debt since the early 1960s results indicate that the share was affected over the long run not only by changing information and reserve requirement costs but also by shifts in relative regulation of bank versus nonbank credit sources such as basel i in 1990 and reregulation in 2010 in the short run the shadow bank share rose when deposit interest rate ceilings were binding on traditional banks the economic outlook improved or risk premia declined and fell when event risks arose

renewable energy sector development in the caribbean current trends and lessons from history island regions and isolated communities represent an understudied area of not only clean energy development but also of innovation caribbean states have for some time shown interest in developing a regional sustainable energy policy and in implementing measures which could help to protect its member states from volatile oil markets while promoting reliance on local resources here we examine four case studies of renewable energy advancements being made by public utility companies and independent energy companies in the caribbean we attempt to locate renewable energy advances in a broader historical framework of energy sector development indicating a few policy lessons we find that different degrees of regulatory and legislative sophistication have evolved in different islands islands should have specialized policy focus contrasting the ad hoc nature of current regional energy policy discussion we also conduct a cost benefit analysis which shows that these early innovative alternative energy projects show themselves to be both profitable and significant sources of emissions reduction and job creation this lends support to the potential benefits of regional energy policy

entrepreneurial moral hazard and bank monitoring a model of the credit channel abstract this paper develops a model of the choice between bank and market finance by entrepreneurial firms that differ in the value of their net worth the monitoring associated with bank finance ameliorates a moral hazard problem between the entrepreneurs and their lenders the model is used to analyze the different strands of the credit view of the transmission of monetary policy in particular we derive the empirical implications of a broad credit channel and compare them to those obtained when the model is extended to incorporate some elements of the bank lending channel

power sector reform in small island developing states what role for renewable energy technologies abstract due to various pressures and desires more and more developing countries embark on power sector reform programmes yet there are a wide range of reform options and at present insufficient evidence is available as to which path will deliver best the desired objectives presently most small island developing states sids are dependent on high cost fossil fuel imports for power generation in spite of evidence that harnessing abundant domestic renewable sources of energy can deliver environmental social and economic benefits however depending on the type of power sector reform the transition towards renewable energy technologies rets can be either undermined or facilitated the specific focus on sids is justified because they have inherent characteristics that limit the degree to which the power sector can be transformed in comparison to larger continental developing countries with specific reference to sids this manuscript reviews the drivers and desires for power sector reform as well as presenting the available reform options and their implications on the up take of rets in addition to elaborating aspects of market governance other barriers to the consideration of rets such as financial bias in investment human capacity and environmental policy are discussed in view of this discussion which is based on evidence from recent reform programmes and theoretical academic literature recommendations are formulated that discourage full privatisation of the power sector as well as proposing less dogmatic lending conditions by international assistance bodies

one sided sustainability tests with amenities and changes in technology trade and population abstract if an economy with multiple consumption goods including environmental amenities uniquely maximises present value with constant discounting it is unsustainable at some time if either of two measures augmented net investment or the change in augmented green net national product are zero or negative then augmented denotes that time is treated as a productive stock which includes in each measure the value of future exogenous changes in technology or terms of trade adjustments are found to make each measure a test for individual sustainability when population grows exogenously the practical and philosophical rationale for testing sustainability in a present value maximising and therefore fully prescribed development path is discussed

gender specific starting point bias in choice experiments evidence from an empirical study abstract in this paper we test whether preferences and willingness to pay estimates obtained in a choice experiment study are susceptible to starting point bias as is often the case in dichotomous choice contingent valuation studies on the basis of a multinomial probit model we find that preferences are indeed susceptible to starting point bias in a split sample design our results suggest that varying the price levels displayed in a so called instructional choice set presented prior to the actual preference eliciting choice sets significantly impacts respondents preferences and willingness to pay for protecting danish nature areas from new motorway development in particular our results show that the bias is gender specific only female respondents are significantly affected results further reveal that the impact of the starting point bias decays as respondents evaluate more and more choice sets this supports the discovered preference hypothesis and on the basis of this we suggest a number of ways to potentially mitigate the starting point bias

bank assets liquidity and credit cycles abstract we study how bank collateral assets and their pledgeability affect the amplitude of credit cycles to this end we develop a tractable model where bankers intermediate funds between savers and borrowers if bankers default savers acquire the right to liquidate bankers assets however due to the vertically integrated structure of our credit economy savers anticipate that liquidating financial assets i e loans is conditional on borrowers being solvent on their debt obligations this friction limits the collateralization of bankers financial assets beyond that of real assets i e capital in this context increasing the pledgeability of financial assets eases more credit and reduces the spread between the loan and the deposit rate thus attenuating capital misallocation as it typically emerges in credit economies a la kiyotaki and moore 1997 we uncover a close connection between the collateralization of bank loans macroeconomic amplification and the degree of procyclicality of bank leverage

review of barriers to the dissemination of decentralized renewable energy systems abstract this paper reviews the available literature dealing with the barriers to the dissemination of decentralized renewable energy systems decentralized renewable energy systems may face a range of technical economic institutional socio cultural and environmental barrier to their dissemination in the paper barriers impeding the dissemination of decentralized renewable energy systems have been identified and assessed in addition appropriate remedial measures and corresponding responsibility centers as reported in the literature have also been discussed inappropriateness of technology unavailability of skilled manpower for maintenance unavailability of spare parts high cost lack of access to credit poor purchasing power and other spending priorities unfair energy pricing lack of information or awareness and lack of adequate training on operation and maintenance of decentralized renewable energy systems are found to be the most critical barriers long term conducive policies appropriate regulatory framework financial incentives capital subsidies and soft loans to users technology and skill development internalization of externalities in the cost of energy withdrawal of subsidies presently being given to fossil fuels development of specialized institutions cooperation with international agencies participation of local community and awareness generation have been recommended for increased dissemination of decentralized renewable energy systems

green net value added as a sustainability metric based on life cycle assessment an application to bounty paper towel abstract sustainability measurement in economics includes assessment of environmental and economic effects in an integrated manner in this study system level economic data are integrated with environmental impacts determined from a life cycle assessment lca of a common product we adopt a costing methodology that captures conventional costs but additionally incorporates externality costs to present a convenient easily interpretable metric green net value added gnva is a type of full cost accounting that incorporates total revenue the cost of production depreciation and environmental externalities we present externality costs disaggregated by upstream sectors full cost of production and gnva to evaluate the relative sustainability of bounty paper towels manufactured at two production facilities we found that the longer running more established line had a higher gnva the predominant components contributing to externality costs come from the stationary sources in the supply chain electricity generation 27 35 refineries 20 21 pulp and paper making 15 23 health related externalities from particulate matter pm2 5 and carbon dioxide equivalent co2e emissions are to a great extent driven by electricity usage and emissions by the facilities followed by pulp processing and transport supply chains for other facility purchases product distribution and end of life management contribute the least to the environmental health related costs

genuine savings and sustainability genuine savings gs has emerged as the leading economic indicator of sustainable economic development at the country level it derives from the literatures on weak sustainability wealth accounting and national income accounting we discuss the theoretical underpinnings of gs focusing on the relationship between changes in a nation s extended capital stock and the future path of consumption the indicator has entered widespread use propelled by the world bank s publications despite its varying performance as a predictor for future consumption notwithstanding the extensive body of literature reviewed promising future research avenues are identified

information and bank credit allocation abstract private information obtained by lenders leads to borrower capture to the extent that such information cannot be communicated credibly to outsiders we analyze how this capture affects the loan portfolio allocation of informed lenders first we show that banks charge higher interest rates and finance relatively less creditworthy borrowers in market segments with greater information asymmetries second when faced with greater competition from outside lenders banks reallocate credit toward more captured borrowers flight to captivity third if borrower quality and captivity are sufficiently correlated an increase in the competitiveness of uninformed lenders can worsen the informed lender s overall loan portfolio the model explains observed consequences of financial liberalizations

walk in my shoes nudging for empathy conservation abstract the traditional policy approaches to encourage conservation including offering monetary incentives and direct regulation may lead to unintended consequences which may undermine their effectiveness in this paper we experimentally test the effectiveness of complementing financial nudging incentives with nudging for empathy our framed experiment models a situation in which an upstream farmer influences the water quality downstream by choosing the level of conservation financial nudging is represented by a crop insurance subsidy conditional on conservation compliance consistent with the 2014 farm bill policy empathy nudging is represented by a downstream water user sending a message to the upstream farmer encouraging the latter to walk in the shoes take the perspective of the former we found that empathy nudging can counteract the elimination of financial incentives however it is less effective than financial nudging empathy nudging coupled with financial incentives has a synergic effect and conservation increased significantly compared to using one of the nudges alone furthermore the combination of empathy and financial nudging was particularly effective in low initial conservation cases we argue that policy makers and the public should encourage empathy conservation and that the environmental policy narrative should appeal to empathy and call for farmers to join the cause for conservation and environmental protection

envisaging feed in tariffs for solar photovoltaic electricity european lessons for canada abstract while it is widely agreed that support schemes need to be put in place to promote the use of renewable electricity there is less consensus as to what are the best kinds of strategies to use what is attracting increasing attention in canada is a system of renewable portfolio standards in this all power suppliers are under an obligation to ensure that a certain percentage of the electricity they generate is from renewable resources they can either generate that electricity themselves or purchase green certificates from those who have used renewables to generate electricity recent experience from europe however suggests that a whole hearted commitment to this single strategy could be premature and potentially damaging for the development of all kinds of renewable electricity in canada solar photovoltaics included on the other side of the atlantic ocean the use of so called feed in tariffs that is an obligation for utilities to purchase at a set price the electricity generated by any renewable energy resource is widely credited with accelerating the development of renewable electricity in many countries the purpose of this article is to reflect upon this european experience with feed in tariffs to stimulate discussions regarding what promise they might hold for the development of solar photovoltaic electricity in canada the article is divided into three main sections in the first section policies to promote renewable electricity presently in place in different parts of canada are reviewed attention is then focused more specifically in the second section of this article upon feed in tariffs after defining and describing this alternative system experiences in the countries of the european union are reviewed the main strengths and weaknesses of feed in tariffs in the european experience are also examined the focus then moves back to canada in the third section of the article in this a system of feed in tariffs is proposed for the province of ontario in order to provide just one example of the kind of support that could be forthcoming

financial crisis and credit crunch in korea evidence from firm level data abstract this paper analyzes the credit crunch following the recent financial crisis in korea using enterprise level data we find that there were big differences in the magnitude of the credit contraction across different types of firms in particular chaebol conglomerate affiliated firms appeared to have lost the preferential access to credit that they had enjoyed in the pre crisis period and credit appears to have been reallocated in favor of more efficient firms this suggests that the credit crunch suffered by certain sectors can be attributed to the adjustment by banks and enterprises to the restructuring of the financial sector rather than tight monetary policy or an external credit constraint

comparing augmented sustainability measures for scotland is there a mismatch we estimate and compare two empirical measures of the weak sustainability of an economy for the first time the change in augmented green net national product gnnp and the interest on augmented genuine savings gs yearly calculations are given for each measure for scotland during 1992 1999 augmentation means including using projections to 2020 changed production possibilities enabled by exogenous technical progress or changing oil prices the change in augmented gnnp and the interest on augmented gs are both always positive showing no sustainability problem for scotland then according to the assumptions underlying our weak sustainability calculations however the former greatly exceeds the latter even when macroeconomic fluctuations are taken into account this is a mismatch which poses an unresolved problem with the theory resolving it may require respecifying the utility functions used in mainstream growth theory

augmenting the world bank s estimates ireland s genuine savings through boom and bust abstract the world bank computes estimates of genuine savings gs a leading indicator of sustainable development for most countries a well established literature has called for methodological enhancement this paper presents augmented estimates of irish gs throughout a period of unprecedented economic expansion and decline 1990 2016 a time series constructed predominantly from national sources includes the most comprehensive coverage of pollutants in the literature surveyed we apply a novel method to aid the property rights designation assessment required for transboundary pollutant accounting in sharp contrast to the world bank s estimates our findings suggest that a modern developed economy can exhibit signs of unsustainability furthermore extended environmental damages drive these results suggesting expanded country specific gs may diverge considerably from the world bank s estimates we find rapid economic development and rapid declines in environmental damages can occur concurrently and on the transition away from an unsustainable path

renewable energy in russia markets development and technology transfer abstract five potential markets in russia offer commercial opportunities for renewable energy that are nearly cost competitive with conventional forms of energy grid connected electricity from wind power electricity for villages and small settlements from hybrid wind diesel and biomass district heating for buildings from biomass hot water for buildings from solar thermal and electricity and heat from geothermal over the last several decades the soviet union conducted research and development on several forms of renewable energy technological infrastructure scientific and technical knowledge engineering and technical skills and factories and equipment are all well developed assets but the translation of these assets into commercial renewable energy technologies and markets is a problem because associated market oriented skills and institutions are still lacking many barriers also exist including lack of information and demonstration experience lack of long term commercial financing a perceived climate of high investment risk technology acceptance some direct and indirect energy price subsidies most energy prices have risen to market levels utility monopolies and the absence of operational regulatory frameworks for independent power producers and historical enterprise specialization market intermediation is very important for renewable energy investments and technology transfer providing the knowledge information skills services financing and analysis that is necessary to overcome barriers joint ventures with foreign multinational corporations represent another important means for overcoming barriers one that takes advantage of russian technological capabilities four case studies illustrate the most prominent examples of renewable energy technology transfer with russia ukraine and the baltic states during the period 1992 1996

a framework for evaluating wtp for bipv in residential housing design in developing countries a case study of north cyprus this paper explores people s preferences for a built in photovoltaic bipv renewable energy system to be integrated into housing construction a novel methodology was developed to study the case of northern cyprus for better understanding of possibilities that abound in bipv integration the methodology incorporates building information modeling bim as a real time design and economic assessment tool for bipv choices this serves to benefit both the construction companies and potential house owners in their decision making in addition it uses a contingent valuation cv method to assess the willingness to pay wtp and the willingness to accept wta compensation the results indicate that the capital cost of pv is not instrumental in choice and a lower feed in tariff could be acceptable

on evaluation costs in strategic factor markets the implications for competition and organizational design this paper uses a formal model to study how evaluation costs affect competition for resources in strategic factor markets it finds that relative scarcity may not always benefit resource sellers rather when competition among resource investors passes a certain threshold intensity miscoordination among investors increases to the point that sellers expected profits decline this paper extends the model to consider how investors organize to overcome managerial agency in resource evaluation two organizational designs are considered a incentivization wherein a lower level manager is motivated by an incentive contract to evaluate resources for an investor and b supervision wherein evaluation is either handled directly or closely monitored by headquarters the model suggests that competition among investors will be associated with a greater use of supervision and that investors using supervision will tend to make lower offers this paper also finds that supervision will be more common when valuable resources are rare this paper was accepted by bruno cassiman business strategy

do increases in energy efficiency improve environmental quality and sustainability governments world wide increasingly see energy efficiency as an important aspect of sustainability however there is a debate in the literature as to whether the impact of improved energy efficiency on reducing energy use might be partially or more than wholly offset through rebound and backfire effects this paper clarifies the theoretical conditions under which such effects would occur and explores their likely significance using a computable general equilibrium cge model of the scottish economy we find that for scotland a general improvement in energy efficiency in the production sectors of the economy initially produces rebound effects that eventually grow into backfire energy use ultimately increases in response to an efficiency gain and the ratio of gdp to co2 emissions falls the economic factors underpinning rebound effects are straightforward energy efficiency improvements result in an effective cut in energy prices which produces output substitution competitiveness and income effects that stimulate energy demands however the presence of strong rebound or even backfire does not mean that efficiency enhancing policies are irrelevant rather it suggests that such policies operating alone are insufficient to generate environmental improvements the implication is that a co ordinated portfolio of energy policies is required

measuring sustainability a time series of alternative indicators for scotland this paper presents results from a time series analysis of seven alternative measures of sustainability for scotland the measures chosen are green net national product genuine savings ecological footprint environmental space net primary productivity the index of sustainable economic welfare and the genuine progress indicator these are all measures at the national or macro level we note arguments in the literature that no one single measure of sustainability is likely to be sufficient however very different messages concerning the sustainability of scotland over the period in question 1980 1993 emerge from these measures chosen we also argue that different indicators provide different insights for policy making

harmonization of renewable electricity feed in laws in the european union this paper focuses on the harmonization of feed in laws in the european union as a support mechanism for the promotion of renewable electricity in particular it proposes a methodology for harmonization based on a feed in law with a modular and transparent premium for renewable electricity producers this premium considers technology costs some grid services political incentives and national priorities the proposed approach includes flexibility mechanisms to update and revise premiums to avoid windfall profits for producers and to share technology innovation benefits with electricity consumers while maintaining incentives for innovation our approach is based on the review of the main features of the german and spanish feed in laws and takes into account other necessary considerations for harmonization such as grid access funding definitions and standards ownership of rights derived from renewables and exceptions for small non commercial producers and energy intensive industries

heterogeneous borrowers liquidity and the search for credit abstract we develop a general equilibrium model of credit formation where borrowers and lenders must search for matches and where the composition of borrowers adjusts to satisfy equilibrium entry conditions when market liquidity dries up as a result of fundamental shocks to the system fewer borrowers will participate in the credit market with low quality borrowers suffering disproportionately because of a flight to quality however less liquid credit markets need not be associated with lower social output because the effect of higher average quality may outweigh that of reduced market participation depending crucially on the source of the liquidity shock

policy instruments fostering wind energy projects a multi perspective evaluation approach abstract during the last decade a large number of policy instruments have been developed and implemented all over europe aiming at supporting renewable energy project development however the success of the different policy approaches varies significantly given the very different mechanisms of the diverse instruments the design or the selection of appropriate instruments may cause methodological difficulties in order to support instrument selection economists have developed several evaluation criteria however this paper states that most of the typically proposed and applied criteria catalogues still neglect the interests and requirements of important stakeholder groups this paper therefore proposes a more integrated evaluation approach taking into account the different interests of all relevant stakeholder groups in the three fields renewable energy business especially wind industry policy making and conventional power business

world bank gef solar home systems projects experiences and lessons learned 1993 2000 abstract twelve projects provide energy services to off grid rural households in developing countries by enhancing markets for solar home systems and by removing barriers to their dissemination project approaches are reviewed along with early implementation experience and lessons suggested by experience most projects incorporate the following features pilot private sector and ngo delivery models pilot consumer credit delivery mechanisms pay first cost subsidies and offer affordable system sizes support policy development and capacity develop codes and standards and establish certification testing and enforcement institutions and conduct consumer awareness and marketing programs most projects are just beginning implementation a few are almost completed lessons from early experience suggest that solar home system delivery firms face a myriad of difficulties operating in rural areas credit risk is a serious concern of both financiers and dealers and makes credit sales particularly challenging technical performance of systems is becoming well proven customers desire a range of component options and service levels and can benefit from even small systems projects must recognize the link between rural electric grid extension and solar home system demand and marketing campaigns can be extremely costly and time consuming in rural areas challenges are to demonstrate sustainable and replicable business models develop regulatory models for energy service concessions and integrate rural electrification policy with solar home system delivery

trade credit for supply chain coordination abstract trade credit is a seller s short term loan to the buyer allowing the buyer to delay payment of an invoice it has been the largest source of working capital for a majority of business to business firms in the united states numerous theories have been proposed to explain trade credit mainly from finance perspectives it has also been an important issue in supply chain management surprisingly most literature in supply chain management has examined the retailer s stocking policies given a supplier s trade credit this paper attempts to shed light on trade credit from a supplier s perspective and presents it as a tool for supply chain coordination specifically we explicitly assume firms financial needs for inventory following a newsvendor framework we assume that the supplier grants trade credit and markdown allowance given the supplier s offer the retailer determines order quantity and the financing option for the inventory either trade credit or direct financing from a financial institution our result shows that the supplier s markdown allowance alone cannot fully coordinate the supply chain if the retailer employs direct financing positive financing costs call for trade credit in order to subsidize the retailer s costs of inventory financing using trade credit in addition to markdown allowance the supplier fully coordinates the retailer s decisions for the largest joint profit and extracts a greater portion of the maximized joint profit

the context for substitutes in cvm studies some empirical observations abstract the purpose of this paper is to report results from a set of experiments that provide data to test the noaa 13 panel recommendation that subjects be reminded of budgetary substitutes when providing values the results suggest that simply reminding subjects of alternative environmental goods does not affect the distribution of values for a specific good such values are affected however whenever subjects simultaneously value alternative goods

policy measures to promote the widespread utilization of renewable energy technologies for electricity generation in the maldives abstract this study adopts a stakeholder based approach to understand the size and nature of the market and financial barriers to the widespread utilization of renewable energy technologies rets in the maldives in light of these barriers and the interests of relevant stakeholders this study evaluates different policy options in terms of their suitability to develop a domestic market for rets in the maldives evaluating the different policy instruments it was found that pricing laws that regulate market access are more suitable than quota systems provided that the current subsidies for conventional energy are removed or shifted towards rets as for the other financial incentives rebates on investments and low interest loans should be provided to ret project developers to overcome the high initial project costs in addition to these measures the limited institutional capacity suggests that policy support should also focus on enabling the steady development of regional institutions rather than on supporting individual ret projects these institutions should enable islands in each atoll to take advantage of efficient management and access to financial capital this will allow the development of sustained renewable energy projects that in turn will result in increased renewable capacity and decreased costs

filling the gaps policy supports and interventions for scaling up renewable energy development in small island developing states abstract sids have both opportunities and challenges economic social and environmental vulnerability for low carbon development economically they are highly dependent on international trade they have limited domestic markets too small to provide significant scale economies their exports are constraint by their isolation and remote location we provide an overview of current energy situation in sids their goals to adopt low carbon economic development paths policies already in place or required to achieve the goals and challenges to implement their plans and strategies the focus is on energy policy landscape that needs to be addressed in order to scale up renewable energy technologies needed to stimulate low carbon economic growth we find that sids face four key barriers to renewable energy development information to improve the energy information network by strengthening existing information systems and building awareness of renewable energy financing mechanisms for renewable energy projects including regional loan structures and technical assistance to banks policy supports to implement regulatory frameworks that enable renewable energy development and building technical capacity among players in the renewable energy field we recommend policy enablers that underlie what could positively impact on renewable energy goals and more broadly energy efficiency and climate change

renewable energy adoption in an ageing population heterogeneity in preferences for micro generation technology adoption abstract many countries are endeavouring to supply more of their energy from renewable resources such countries are also experiencing an aging population with a greater proportion of people aged 65 years this demographic shift may reduce the uptake of renewable energy if older person households are less inclined to accept change and adopt new technologies this paper assesses whether such households have different behavioural responses to energy efficiency compared to the rest of society and investigates whether micro generation renewable energy technologies are less likely to be adopted by these households it uses conditional logit and mixed logit models to investigate the impact of age of household on primary heating adoption and also to assess the impact of older households on the installation of discretionary micro generation technologies solar thermal solar voltaic and wind power to supplement existing heating and lighting systems results indicate that primary heating choice is not affected but that older person households are less inclined to adopt micro generation technologies

assessment of the theory of comprehensive national accounting with data for portugal we present time series tests of the quality of genuine savings and green net national income for predicting welfare changes these tests check the validity of the theory of comprehensive national accounting and more broadly of the theory of economic growth the value of technological progress is included as well as the effects of business cycles we use estimates for portugal as inputs overall our results indicate that both genuine savings and changes in green net national income have the same sign as changes in welfare but reject the hypothesis that the estimated comprehensive national accounting measures coincide with the theoretical expressions the results also suggest that comprehensive accounting indicators perform better than conventional national accounting indicators implying that in general the corrections proposed by the comprehensive accounting theory add explanatory power to conventional measures the exception is the inclusion of education expenditures and technological progress which decrease explanatory power excluding business cycles from green net national income increases the agreement with the theory comparing both indicators in general genuine savings presents better results

measuringincome and measuring sustainability we examine what interpretation can be given to inclusive income understood to be consumption plus the value of the net increase in all relevant capital stocks we introduce the concept of instantaneously constant value income defined as the maximum amount the economy can consume at a moment of time and keep the expected present value of utility of current and future generations constant we argue that this income concept captures some of the concerns underlying sustainability our main result is that inclusive income equals instantaneously constant value income we show that this result holds in a very general setting and in particular carries over to models incorporating technological progress when such progress can be captured by augmented stocks of knowledge an important implication of our main result is that it provides a very simple method for deriving inclusive income which does not involve any linearization of the hamiltonian

learning and fatigue effects revisited investigating the effects of accounting for unobservable preference and scale heterogeneity using multiple choice tasks per respondent in discrete choice experiment studies increases the amount of available information however respondents learning and fatigue may lead to changes in observed utility function preference taste parameters as well as the variance in its error term scale they need to be controlled to avoid potential bias a sizable body of empirical research offers mixed evidence in terms of whether these ordering effects are observed we point to a significant component in explaining these differences we show how accounting for unobservable preference and scale heterogeneity can influence the magnitude of observed ordering effects

natural resources national accounting and economic depreciation abstract the current value hamiltonian in an aggregate optimal growth problem with heterogeneous capital stocks including exhaustible renewable and environmental stocks is the nnp function routine substitutions reveal that the using up of natural resource stocks is representable as easy to interpret economic depreciation magnitudes we obtain true nnp inclusive of natural resource stock diminution implications for actual national accounting practices are also discussed

resolving questions about bias in real and hypothetical referenda despite 10 years of research on behavior in hypothetical referenda conflict remains in the literature on whether or not the mechanism generates biased responses compared to real referenda and the nature and source of any such bias almost all previous inquiry in respect of this issue has concentrated on bias at the aggregate level this paper reports a series of three experiments which focuses on bias at the individual level and how this can translate to bias at the aggregate level the authors argue that only an individual approach to hypothetical bias is consistent with the concept of incentive compatibility the results of these experiments reflect these previous conflicting findings but go on to show that individual hypothetical bias is a robust result driven by the differing influence of pure self interest and other regarding preferences in real and hypothetical situations rather than by a single behavioral theory such as free riding in a hypothetical situation these preferences cause yea saying and non demand revealing voting this suggests that investigation of individual respondents in other hypothetical one shot binary choices may also provide us with insights into aggregate behavior in these situations

resource depletion and sustainability in small open economies abstract exogenous price changes affect the amount that a small country exporting natural resource commodities must invest to sustain its consumption level the necessary amount is given by the difference between hotelling rent and the discounted sum of future terms of trade effects capital gains the latter term is found to be large relative to the former in the case of petroleum depletion in indonesia this suggests that resource rich countries will need to invest more than previously expected to sustain their consumption levels if natural resource prices continue their long term historical decline

using ex ante approaches to obtain credible signals for value in contingent markets evidence from the field while contingent valuation remains the only option available for measurement of total economic value of nonmarketed goods the method has been criticized due to its hypothetical nature we analyze field experimental data to evaluate two ex ante approaches to attenuating hypothetical bias directly comparing value statements across four distinct referenda hypothetical cheap talk consequential and real our empirical evidence suggests two major findings hypothetical responses are significantly different from real responses and responses in the consequential and cheap talk treatments are statistically indistinguishable from real responses we review the potential for each method to produce reliable results in the field

credit reallocation deleveraging and financial crises this paper studies how the process of reallocation of credit across firms behaves before and after financial crises applying the methodology typically used for measuring job reallocation we track credit reallocation across korean firms for over three decades 1980 2012 the credit boom preceding the 1997 crisis featured a slowdown of credit reallocation after the crisis and the associated reforms the creditless recovery deleveraging masked a dramatic intensification and increased procyclicality of credit reallocation the findings suggest that the intensification of reallocation was efficiency enhancing

empirical testing of genuine savings as an indicator of weak sustainability a three country analysis of long run trends genuine savings has emerged as a widely used indicator of sustainable development this approach to conceptualising what sustainability is about has strong links to work published by anil markandya and colleagues over 20 years ago in this paper we use long term data stretching back to 1870 to undertake empirical tests of the relationship between genuine savings gs and future well being for three countries britain the usa and germany our tests are based on an underlying theoretical relationship between gs and changes in the present value of future consumption based on both single country and panel results we find evidence supporting the existence of a cointegrating long run equilibrium relationship between gs and future well being and fail to reject the basic theoretical result on the relationship between these two macroeconomic variables this provides some support for the gs measure of weak sustainability

wind electricity in denmark a survey of policies their effectiveness and factors motivating their introduction this paper surveys the development of the policies supporting the introduction of wind electricity in denmark in the last 15 years with special attention to the new policy introduced after a 2 year long debate the aim of this paper is to explore the roles of financial support policy certainty and planning constraints in the diffusion of wind electricity in denmark and the reasons prompting the change of the system in the current decade it is discovered that political uncertainty has badly affected the effectiveness of the feed in law in the years immediately after its introduction with regard to the new system it is concluded that the change has been prompted by generous conditions under the feed in law and by the desire to facilitate the modernisation of old turbines it is also concluded that incentive based systems can be more effective than tradable quotas in promoting the modernisation of renewable plants this finding is relevant to the development of energy policy in countries such as germany and spain where the average age of wind turbines is much younger than those existing in denmark

sustainability constraints versus optimality versus intertemporal concern and axioms versus data sustainable sustained or survivable development are defined here as distinct sustainability constraints on intertemporal distribution in a context which ignores uncertainty environmental and intratemporal concerns such constraints are neither self contradictory nor redundant for they can conflict with maximizing the present value of utility optimality nor inferior since the axioms underlying optimality are ethically arbitrary and refuted by empirical psychological data axiomatic arguments may clarify but cannot resolve debates about intertemporal concerns data suggest that sustainability constraints are not respected and that intertemporal welfare functions containing a preference for sustained improvement may better reflect what bodies politic mean by sustainability

does realism matter in contingent valuation surveys the importance of stressing the realism or policy relevance of a contingent valuation cv survey is commonly recognized by cv researchers this paper focuses on the relationship between the probability that a subject s response will result in real consequences and the subject s accurate reporting of willingness to pay results from experiments support the argument that efforts to make contingent valuation surveys real are important however our results also suggest that the connection between the survey and the likelihood of a payment must be rather powerful before surveys generate accurate reporting of willingness to pay for a public good

the money market meltdown of the great depression consistent with theories of financial frictions this study finds that higher corporate risk premia and flight to quality events contributed to the increased use of a collateralized form of business lending bankers acceptances in real levels and relative to that of noncollateralized commercial paper which plunged during the great depression these short lived instruments are more timely measures of credit availability than are bank business failures and bank loan outstandings these shifts in the composition of external finance were large supporting the view that financial frictions rose and credit availability fell during the great depression

the changing structure of local credit markets are small businesses special abstract in many countries consolidation in the banking industry has reduced the number of small banks and led to significant shifts in market shares deregulation has fostered entry in local credit markets and the expansion of branch networks increasing competition in local markets small businesses are believed to be more vulnerable to these changes since they are more dependent on credit from local banks in this paper we investigate the consequences of consolidation and entry for these borrowers compared with those for large firms we employ a data set for italy which provides information on volumes of loans and bad loans by size of borrower with a detailed geographical partition we find that mergers are followed by a temporary reduction in outstanding credit to all sizes of borrowers and by an increase in bad loans most likely due to the reassessment of banks portfolios entry has a relatively persistent negative impact on credit supply to small and medium sized firms our results also show that concentration branch density and the share of branches of small banks affect the volumes of credit and bad loans of small borrowers
