governmental intervention approaches to promote renewable energies special emphasis on japanese feed in tariff abstract almost all countries have issued laws and regulations to promote renewable energy re however the applications and motivations of such laws as well as achievements have been different currently the japanese government has announced its targets to expand the electricity feed in tariff scheme for solar power along with other energy sources within two years to meet the goal set by the japanese prime minister who in the 15th united nations climate change conference cop15 held in september 2009 proclaimed to cut 25 of greenhouse gas ghg emissions from the 1990 levels by 2020 in this paper the current japanese energy policies and measures for promoting re in comparison to popular methods followed worldwide are explored furthermore a least cost feed in tariff lcfit simulation model for japanese case was developed to calculate the optimal mix of technologies to reach certain targets the lcfit also calculates the tariff that should be proposed for each technology and the total cost for the program with and without a carbon tax and estimates the premium added to the bill of the customer every month

price determination in the eu ets market theory and econometric analysis with market fundamentals abstract we investigate the price determination of the european union emission allowance eua of the european union emissions trading scheme eu ets we postulate an uncertain permit price and risk averse firms which have the possibility to hedge in the forward market the firms produce final goods abate their emissions and trade permits in the permit market the dependence of the equilibrium permit price on exogenous variables is studied in a permit market model we test our theoretical findings with empirical data from 2005 to 2010 in the eu ets market we use daily forward prices of eua as our dependent variable we use several econometric models with multiple stationary time series to discover that there is a strong relationship between the fundamentals such as german electricity prices and gas and coal prices with the price of eua we find that the eua forward price depends on fundamentals especially on the price of electricity as well as on the gas coal difference in a statistically significant way

marketable pollution permits in oligopolistic markets with transaction costs in this paper we present a variational inequality framework for the modeling qualitative analysis and computation of equilibrium patterns in multiproduct multipollutant oligopolistic markets with marketable pollution permits in the presence of transaction costs the model deals explicitly with spatial differentiation and also guarantees that the imposed environmental quality standards are met through the initial allocation of licenses an algorithm is proposed with convergence results to compute the profit maximized quantities of the oligopolistic firms products and the quantities of emissions along with the equilibrium allocation of licenses and their prices numerical examples are included to illustrate this approach

china s carbon emissions trading overview challenges and future because china has emerged as the largest greenhouse gas ghg emitter in total annual emissions to accelerate the pace of ghg emission reduction in china is important to the success of global efforts in addressing climate change carbon trading is a market mechanism and key instrument in the mitigation of climate change this paper explores the policy process and development state to date of china s carbon trade market to understand the emergence and development of that market and to understand what barriers are hampering china s carbon trade market development to achieve this goal this paper introduces and analyzes china s status in the international market examines the factors driving carbon market launching by the chinese government and traces the development of mandatory carbon emission trading and voluntary emission trading it is argued that china s carbon trading market is confronted with challenges such as the absence of a functional carbon trading market inaccuracy of the quota allocation an imperfect trading mechanism and lagging legislation at the present stage shortcomings such as having no real time carbon price and dominated spot transactions differentiate china s trade market substantially from a functional system a quick market integration of china s carbon market appears remote it is suggested that specific measures be taken to promote the development of the chinese carbon trading market

assessing the combined effect of the diffusion of solar rooftop generation energy conservation and efficient appliances in households abstract there is a growing worldwide concern regarding emissions of energy related greenhouse gases ghgs policy technology and human awareness provide opportunities for offsetting these effects through energy conservation efficient appliances and solar generation in households as these have been the subject of increasing attention across the world in recent years solar rooftop generation in particular could deliver significant efficiency improvements and reductions of co2 emissions through its diffusion which also avoids losses in electricity transmission and distribution systems energy efficiency contributes to the achievement of a sustainable future because it reduces the energy infrastructure needs increases competitiveness and improves consumer welfare conservation would also reduce co2 emissions in households the purpose of this paper is to assess the combined effect of the diffusion of solar rooftop generation energy efficiency and electricity conservation in the residential sector in colombia simulation results for different policy scenarios indicate that rooftop generation energy efficiency and conservation can together lead under certain conditions to important reductions in both electricity prices and emissions

agent based computational transaction cost economics this article explores the use of agent based computational economics ace for modelling the development of transactions between firms transaction cost economics neglects learning and the development of trust ignores the complexity of multiple agents and assumes rather than investigates the efficiency of outcomes efficiency here refers to minimum cost or maximum profit we model how co operation and trust emerge and shift adaptively as relations evolve in a context of multiple interacting agents this may open up a new area of application for the ace methodology a simulation model is developed in which agents make and break transaction relations on the basis of preferences based on trust and potential profit profit is a function of product differentiation specificity of assets economy of scale and learning by doing in ongoing relations agents adapt their trust in a partner as a function of his loyalty exhibited by his continuation of a relation they also adapt the weight they attach to trust on the basis of realized profit the model enables an assessment of the efficiency of outcomes relative to the optimum as a function of trust and market conditions we conduct a few experiments to illustrate this application of ace

heuristic learning and the discovery of specialization and exchange abstract i develop and calibrate an agent based model of boundedly rational adaptive agents in a two good production and exchange economy to replicate human subject outcomes in the same eight person experimental economy to test agents ability to capture human behavior i extend the model and use its output to make predictions about a second experimental environment in which the group of eight agents is slowly constructed by merging smaller groups this environment improves human subject performance in the specialization and exchange task and commensurate improvement emerges for some parameterizations of the agent based model this iterative process yields incremental improvement of decision level theories about economic discovery

will markets direct investments under the kyoto protocol lessons from the activities implemented jointly pilots under the kyoto protocol countries can meet treaty obligations by investing in projects that reduce or sequester greenhouse gases elsewhere prior to ratification treaty participants agreed to launch country based pilot projects referred to collectively as activities implemented jointly aij to test novel aspects of the project related provisions relying on a ten year history of projects we investigate the determinants of aij investment our findings suggest that review agency preferences related to national political objectives and possibly deeper cultural ties influenced project selection and limited the number of aij projects bilateral ties also appear to have affected investment decisions directly possibly because of related transaction costs the results suggest an investment process different from the assumptions that underlie well known estimates of cost savings related to the protocol s flexibility mechanisms we conclude that if approaches developed under the aij programs to approve projects are retained the scale of investment under kyoto s flexibility provisions and their cost savings will be less than what is generally anticipated and the pattern of investment less driven by abatement costs

agency relationships in family firms theory and evidence does owner management necessarily eliminate the agency costs of ownership drawing on agency literature and on the economic theory of the household we argue that private ownership and owner management expose privately held owner managed firms to agency threats ignored by jensen s and meckling s 1976 agency model private ownership and owner management not only reduce the effectiveness of external control mechanisms they also expose firms to a self control problem created by incentives that cause owners to take actions which harm themselves as well as those around them jensen 1994 p 43 thus shareholders have incentive to invest resources in curbing both managerialand owner opportunism we extend this thesis to the domain of the family firm after developing hypotheses which describe how family dynamics and specifically altruism exacerbate agency problems experienced by these privately held owner managed firms we use data obtained from a large scale survey of family businesses to field test our hypotheses and find evidence which suggests support for our proposed theory finally we discuss the implications of our theory for research on family and other types of privately held owner managed firms

second best taxation as a game second best theory usually lies in the realm of normative analysis it focuses attention on the best solutions which still can be obtained in problems where constraints of various natures forbid the attainment of first best pareto optimal situations its central concern is the characterization of such second best solutions and a large part of the literature concentrates on the optimal design of taxes or of policies of public firms taking a second best problem we try in this paper to shift the emphasis from normative to positive considerations the solution we are interested in is not optimal with respect to some a priori given social welfare function embodying justice objectives but it is supposed to reflect the power of the different agents in a negotiation process clearly the conceptual tools required for such an analysis are to be found in game theory and it is actually a game theoretical approach that we follow here the model we are looking at is presented in section ii it formalizes one of the simplest second best problems that can be imagined we have a twogood economy with one private good and one public good agents have different wealth in private good and the public good is financed through a wealth tax this latter fiscal system is clearly not flexible enough to adjust contributions with marginal willingnesses to pay so that we actually face a second best situation there is one decision variable in the society the tax rate which determines the public good production about which the agents have conflicting desires to this problem we associate a game which provides a precise framework for the analysis of the power of the agents the positive outcomes of the negotiation process are supposed to belong to the core of this game sections iii and iv concentrate on the analysis of the core the results strongly contrast with those obtained in the classical studies of the core of 67 0022 053 l 81 040067 25 02 00 o

willingness to pay for car safety evidence from sweden this study estimates a marginal willingness to pay wtp function for a road mortality risk reduction observed marginal wtp from the swedish car market is used and found to be positively correlated with the baseline risk of the cars no statistically significant relationships between examined owner attributes e g wealth and background risk and marginal wtp are found when comparing the estimated monetary value of a non marginal risk reduction derived from the integral of the marginal wtp function with an estimate based on marginal wtp we find in line with expectations that the difference between the estimates is negligible for smaller risk reductions and small 4 10 also for relatively large risk reductions

equilibrium and reinforcement learning in private information games an experimental study abstract this paper examines the abilities of standard game theoretic solution concepts static nash equilibrium and a simple model of individual learning to describe subject behavior in an experiment involving private information games with mixed strategy nash equilibrium outcomes the experimental data are compared in several ways with the predictions of static nash equilibrium and the quite different predictions of the learning model which is based on the models of roth and erev 1995 games and economic behavior special issue nobel symposium vol 8 pp 164 212 nash equilibrium does not adequately describe subject behavior whereas the learning model performs well in describing aspects of the evolution in behavior over time

complexity and the character of stock returns empirical evidence and a model of asset prices based on complex investor learning empirical evidence on the distributional characteristics of common stock returns indicates 1 a power law tail index close to three describes the behavior of the positive tail of the survivor function of returns pr r x x a reflection of fat tails 2 general linear and nonlinear dependencies exist in the time series of returns 3 the time series return process is characterized by short run dependence short memory in both returns as well as their volatility the latter usually characterized in the form of autoregressive conditional heteroskedasticity and 4 the time series return process probably does not exhibit long memory but the squared returns process does exhibit long memory we propose a model of complex self referential learning and reasoning amongst economic agents that jointly produces security returns consistent with these general observed facts and which are supported here by empirical results presented for a benchmark sample of 50 stocks traded on the new york stock exchange the market we postulate is populated by traders who reason inductively while compressing information into a few fuzzy notions that they can in turn process and analyze with fuzzy logic we analyze the implications of such behavior for the returns on risky securities within the context of an artificial stock market model dynamic simulation experiments of the market are conducted from which market clearing prices emerge allowing us to then compute realized returns we test the effects of varying values of the parameters of the model on the character of the simulated returns the results indicate that the model proposed in this paper can jointly account for the presence of a power law characterization of the positive tail of the survivor function of returns with exponent on the order of three for autoregressive conditional heteroskedasticity for long memory in volatility and for general nonlinear dependencies in returns

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

emissions reduction and economic implications of renewable energy market penetration of power generation for residential consumption in the mena region this paper examines the implications of renewable energy re deployment in power generation for residential consumption in the middle east and north africa mena region under various re penetration targets a comparative assessment revealed a great heterogeneity among countries with turkey dominating as the highest emitter at the sub regional level the middle east sub region contributes more than double the ghg emissions estimated for the gulf and north africa sub regions with all sub regions achieving reductions in the range of 6 38 depending on the re target penetration and promising up to 54 savings on investment excluding positive externalities associated with the offset of greenhouse gas ghg emissions savings

transaction costs and institutional performance in market based environmental water allocation policy reforms in the columbia basin spurred water rights reallocation for ecological recovery transaction costs have caused implementation to lag this paper examines transaction costs and institutional performance in environmental water allocation it evaluates spatial and temporal performance trends in watershed cases along three dimensions of adaptive efficiency water recovery transaction costs and program budgets performance trends demonstrate intrastate variability and volatility over time due to the importance of local institutional capacity which is uneven within states higher levels of water recovery may coincide with moderate to high transaction costs and program budgets particularly during initial implementation efforts this finding reflects investments in multilevel policy reform to strengthen enabling conditions and adapt to unintended consequences jel q25 q58

transaction costs in pollution markets an empirical study this paper studies a market in pol lution permits launched in los angeles in 1994 this tradable permit market has been projected to lead to substantial cost savings due to the flex ibility it provides firms in terms of compliance with environmental regulation this paper shows that transaction costs can play an important role in the initial years of the program the transac tion cost variables have been defined to include search costs and information costs these costs are significant in explaining non participation of some firms in the market the study also draws policy implications for the development of future emissions trading programs jel q28 q25

exploring the effect of cap and trade mechanism on firm s production planning and emission reduction strategy abstract cap and trade mechanism has a significant effect on firm s production and operation decisions and carbon emissions this study develops a mathematical model to examine the effect of cap and trade mechanism on firm s production planning and emission reduction strategy based on the model the firm s critical production planning decisions such as the optimal production quantity optimal allowance selling price and the maximum profit under the cap and trade mechanism are derived firstly then based on the cost benefit analysis the conditions under which the firm makes the optimal emission reduction strategy between buying carbon allowance from the carbon trading market and conducting low carbon processing are identified the result suggests that when the low carbon processing cost is greater than the potential opportunity benefit the firm is inclined to purchase carbon allowance from the carbon trading market and vice versa finally a numerical analysis is conducted to investigate the effects of relevant factors such as carbon quotas carbon emission rate low carbon processing cost and transaction cost on firm s production and operation decisions the results indicate that under the cap and trade mechanism the transaction cost has a positive effect on allowance selling price the firm s optimal production quantity and maximum profit is positively related to carbon quotas while negatively related to carbon emission rate and low carbon processing cost this research contributes to enrich related literature and knowledge with regard to carbon emissions reduction at the firm level and highlight the critical importance of cap and trade mechanism in reducing carbon emissions

when to pollute when to abate intertemporal permit use in the los angeles nox market we study intertemporal trading of nitrogen oxides permits in southern california s reclaim program we model reclaim s distinct intertemporal features two overlapping permit cycles and two overlapping compliance cycles in the model competitive equilibrium is cost effective and firms have an incentive to delay abatement from 1994 to 2006 reclaim facilities traded intertemporally by using permits of the opposite cycle we test two theoretical propositions delayed abatement and trading across cycles with a difference in differences estimator and show weak though inconclusive support of the theory the theoretical and empirical results are relevant to cap and trade programs with potential for overlapping permit cycles jel q58

club networks with multiple memberships and noncooperative stability modeling club structures as bipartite directed networks we formulate the problem of club formation with multiple memberships as a noncooperative game of network formation and identify conditions on network formation rules and players network payoffs sufficient to guarantee that the game has a potential function our sufficient conditions require that each player choose freely and unilaterally those clubs he joins and also his activities within those clubs subject to feasibility constraints we refer to our conditions on rules as noncooperative free mobility we also require that players payoffs be additively separable in player specific payoffs and externalities and that payoff externalities a function of club membership club activities and crowding be identical across players externality homogeneity we then show that under these conditions the noncooperative game of club network formation with multiple memberships is a potential game over directed club networks and we discuss the implications of this result

the impact of attribute preferences on adoption timing the case of photo voltaic pv solar cells for household electricity generation we are concerned with micro generation individual households generating electricity using a renewable technology we focus on modeling the adoption probability of photo voltaic solar panels by households using data from ontario canada where a generous feed in tariff is available to households generating electricity from solar panels we measure household level preferences for panels and use these preferences along with household characteristics to predict adoption time intentions we use discrete choice experiments to measure household level preferences and establish a causal link between the attributes of the technology and adoption time intentions using discrete time survival mixture analysis significant preferences included lower cost greater energy savings and lower fossil fuel inflation the conditional hazard probability of adoption at a particular time given no previous adoption showed that the attribute preferences had intuitively reasonable effects the hazard probabilities allow us to compute the cumulative probability of adoption over a 10 year period per household technology awareness has a significant effect on the adoption probability reinforcing the need for effective education our approach indicates the level of heterogeneity in preferences particularly high for investment criteria and co2 emissions these findings suggest that education campaigns should explain more about investment criteria feed in tariffs and environmental effects

seller incentive properties of epa s emission trading auction abstract the new clean air act amendments instruct the environmental protection agency epa to conduct annual sealed bid offer auctions of emission allowances the auction pricing rules are discriminative and sellers with the lowest asking prices receive the highest bids this paper assesses the seller incentives of this auction and demonstrates that the auction rules cause sellers to choose asking prices that under reveal their cost of emission control furthermore increasing the number of sellers intensifies this misrepresentation if the number of buyers remains fixed the epa s rules can therefore generate significantly biased price signals and reduce the efficiency of the allowance trading market

the effect of allowance allocations on cap and trade system performance abstractan implication of the coase theorem is that under certain conditions the market equilibrium in a cap and trade system will be cost effective and independent of the initial allocation of tradable rights that is the overall cost of achieving a given aggregate emission reduction will be minimized and the final allocation of permits will be independent of the initial allocation we call this the independence property this property is important because it means that the government can establish the overall pollution reduction goal for a cap and trade system by setting the cap and leaving it up to the legislature to construct a constituency in support of the program by allocating the allowances to various interests without affecting either the environmental performance of the system or its aggregate social costs we examine the conditions under which the independence property is likely to hold both in theory and in practice

assessment of government support for the household adoption of micro generation systems in korea abstract this paper investigates how korean government support affects household adoption of renewable energy based micro generation systems by analyzing household preferences in relation to the costs and benefits of system installation and different kinds of government support the research adopts a discrete choice experiment approach and focuses on two micro generation technologies solar voltaic and solar thermal our empirical analysis revealed firstly that households prefer micro generation systems that have low installation costs but high energy saving benefits and long warranty periods and secondly that households prefer direct subsidies to low interest loans however we also found that households are reluctant to install photovoltaic or solar thermal systems in reality because they see the cost of system installation as being higher than the benefits they would receive from such installation in short while existing government supports are somewhat effective in promoting household adoption of micro generation systems there also exists the obstacle that the majority of households are unwilling to install such systems despite government support thus several policy improvements which focus on increasing the benefits and decreasing the installation costs of micro generation systems are suggested in this paper

genetic algorithm learning and the cobweb model this paper presents the cobweb model in which competitive firms in a market for a single good use a genetic algorithm to update their decision rules about next period production and sales the results of simulations show that the genetic algorithm converges to the rational expectations equilibrium for a wider range of parameter values than other algorithms frequently studied within the context of the cobweb model price and quantity patterns generated by the genetic algorithm are also compared to the data of experimental cobweb economies it is shown that the algorithm can capture several features of the experimental behavior of human subjects better than three other learning algorithms that are considered

economic prescriptions for environmental problems how the patient followed the doctor s orders o ne of the dangers with ivory tower theorizing is that it is easy to lose sight of the actual set of problems which need to be solved and the range of potential solutions as one who frequently engages in this exercise i can attest to this fact in my view this loss of sight has become increasingly evident in the theoretical structure underlying environmental economics which often emphasizes elegance at the expense of realism in this paper i will argue that both normative and positive theorizing could greatly benefit from a careful examination of the results of recent innovative approaches to environmental management the particular set of policies examined here involves two tools which have received widespread support from the economics community marketable permits and emission charges pigou 1932 dales 1968 kneese and schultze 1975 both tools represent ways to induce businesses to search for lower cost methods of achieving environmental standards they stand in stark contrast to the predominant command and control approach in which a regulator specifies the technology a firm must use to comply with regulations under highly restrictive conditions it can be shown that both of the economic approaches share the desirable feature that any gains in environmental quality will be obtained at the lowest possible cost baumol and oates 1975 until the 1960s these tools only existed on blackboards and in academic journals as products of the fertile imaginations of academics however some countries have recently begun to explore using these tools as part of a broader strategy for managing environmental problems

tradable permits and unrealized gains from trade with the advent of tradable permit programs for bad outputs e g so2 emissions concerns arose over whether the theoretical gains from trade would be realized we will employ a methodology that calculates the potential gains accruing to coal fired electric power plants from implementing a tradable permit program the magnitude of the potential gains in a plant s kilowatt hour output from a tradable permit program relative to its observed production provides insights into the existence of intertemporal allocative inefficiencies and spatial allocative inefficiencies after the implementation of a tradable permit program

a support strategy for the promotion of photovoltaic uses for residential houses in korea various policies such as feed in tariffs quota obligations and capital subsides were enacted to expand the uses of renewable energy re in many countries this study examined whether capital subsidies are cost effective in relation to the installation of solar photovoltaic pv facility to do this the capacity factor which is one of the crucial factors for determining the unit cost of electricity from a solar pv system was estimated from the monthly average clearness index data collected at various cities in korea thermoeconomic analysis was applied to calculate the unit cost of electricity based on the calculated capacity factor of the solar pv system instead of subsidizing the same percent of the capital cost of each pv system installation it is reasonable for the government to adopt a measure to match the subsidy paid to the payback period of the initial investment for all 5 million potential solar pv users in korea

the emissions trading paradox abstract this article considers the price history of co2 allowances in the eu emission trading scheme since european emissions trading started in 2005 the prices of allowances have varied between less than one and thirty euro per ton of co2 this previously unpredicted volatility and more notably a significant price crash in may 2005 led to the hypothesis that electricity producers might use their market power to influence the prices of allowances besides market power the combination of information asymmetry and price interdependencies between prices of primary goods especially electricity and allowances plays an important role in explaining the emissions trading paradox the model presented will show that banking can lead to such a price crash if market participators act rationally furthermore in such a scenario banking can be profitable for sellers at the cost of buyers

a natural experiment approach to contingent valuation of private and public uv health risk reduction strategies in low and high risk countries we present the results of a natural experiment to test how variations in exogenous risk levels affect resultant willingness to pay wtp for risk reduction the case study presented considers wtp for reductions in the skin cancer risks associated with exposure to solar uv radiation a common design contingent valuation survey is conducted in four countries across which variation in geographical latitude and genetic mix mean that exogenous risks differ substantially survey respondents were presented with both a private and public good route for affecting risk reduction in both cases results confirm that once adjustment had been made for expected relationships with other covariates such as income and risk averting behaviour valuation responses for both goods conformed to expectations with the ordering of values across countries reflecting the ordering of scientifically established health risks this suggests that links between values and objective health risks may be observed within such situations and provides a justification for continuing research into more natural representations of risk and risk reductions in order to yield consistent and robust measures of associated values

equilibria in a model with partial rivalry abstract in this paper we show that a non cooperative game with a finite set of players and common finite strategy sets possesses a strong nash equilibrium in pure strategies whenever individuals preferences satisfy independence of irrelevant choices anonymity and partial rivalry moreover if any of these assumptions is violated then even a pure strategy nash equilibrium may fail to exist further more we demonstrate that even with a continuum of players the same three assumptions yield the existence of a pure strategy strong nash equilibrium and in addition the equivalence of the sets of nash and strong nash equilibria in pure strategies journal of economic literature classification numbers c72 d62

the market for sulfur dioxide emissions the 1990 clean air act amendments initiated the first large scale use of the tradable permit approach to pollution control the theoretical case for this approach rests on the assumption of an efficient market for emission rights the authors empirical analysis shows that the emission rights market created by the 1990 amendments had become reasonably efficient by mid 1994 they also show that the auctions specified in the amendments to jump start trading had become a small part of the overall market finally the authors demonstrate that the strategic bidding behavior discussed in the literature has had no effect on market prices copyright 1998 by american economic association

transaction costs and tradeable permits abstract tradeable permit systems are at the center of current interest and activity in market based reforms of environmental policy because these systems can offer significant advantages over conventional approaches to pollution control unfortunately claims made for their relative cost effectiveness have often been exaggerated transaction costs which may be significant in these markets reduce trading levels and increase abatement costs in some cases equilibrium permit allocations and hence aggregate control costs are sensitive to initial permit distributions providing an efficiency justification for politicians typical focus on initial allocations

renewable energy policies in europe converging or diverging abstract nations today are urgently challenged with achieving a significant increase in the deployment of renewable energies in europe that need has given rise to a debate about the most effective and efficient support strategy whilst the different interests debate whether full european harmonisation or strengthening of national support policies for electricity from renewable energy sources res e is the best way forward individual national support schemes are rapidly evolving this study investigates how the eu member states have applied support policy types over the last decade by identifying predominant developments in the application of feed in tariffs premiums tradeable green certificates tax incentives investment grants and financing support for specific technologies wind biomass pv this study shows that europe is currently experiencing certain tendencies towards a bottom up convergence of how national policy makers design res e policy supports while some outliers remain the policy supports of most countries become more similar in the policy types applied dominance of feed in tariffs and in their scope of implementation differentiation for installation sizes and stacking of multiple instruments these trends in national decision making which show tendencies of convergence could make an eu driven top down harmonisation of support either dispensable or at least depending on the agreement less controversial

analysis of prices in tradable emission markets an empirical study of the regional clean air incentives market in los angeles the regional clean air incentives market is an emissions trading programme which is expected to help in reducing oxides of nitrogen and sulphur from stationary sources in the los angeles area this paper uses econometric techniques to determine the factors that can explain the development of the price of emission permits by controlling for various characteristics of the trades the regression results allow one to isolate the impact of each factor and conduct a detailed analysis of the implications of this factor on price the results show that the price of permits is affected by institutional factors such as the trading rules and regulations governing the permit programme the permits are priced higher in the coastal zone higher for trades recorded in 1997 as compared to 1994 or 1995 and are affected by the trader category brokers are involved in well over half of the trades and have acquired a substantial inventory of permits facilities buying from brokers pay higher prices than if they buy from ano

the political economy of pollution markets historical lessons for modern energy and climate planners this article explores some of the central economic and political problems with the use of tradable permits to solve environmental problems drawing from transaction cost economics political economy and market theory it does so by looking at the history of three programs for curbing pollution in the united states the clean air act the leaded gasoline phase out and water permits in wisconsin the article begins by briefly summarizing the history of each of these programs before looking at a host of challenges related to political compromises in program design transaction costs spatial distortions such as geographic sensitivity and wrong way trading of credits temporal distortions such as the episodic nature of pollution and volatility of market prices and market abuses these concerns are raised with an eye for how historical experience may inform the current debate about how to design effective market mechanisms to respond to climate change and other forms of energy related environmental degradation

a learning to forecast experiment on the foreign exchange market with a classifier system abstract this paper reports on an experiment of learning and forecasting on the foreign exchange market by means of an artificial intelligence methodology a classifier system which simulates learning and adaptation in complex and changing environments the experiment has been run for two different exchange rates the us dollar d mark rate and the us dollar yen rate representative of two possibly different market environments a fictitious artificial agent is first trained on a monthly data base from 1973 to 1990 and then tested out of sample from 1990 to 1992 its forecasting performance is then compared with the performance of decision rules which follow the prescription of various economic theories on exchange rate behaviour and the performance of forecasts given by var estimations of the exchange rate s determinants

fishing quota markets abstract in 1986 new zealand responded to the open access problem by establishing the world s largest individual transferable quota itq system using a 15 year panel dataset from new zealand that covers 33 species and more than 150 markets for fishing quotas we assess trends in market activity price dispersion and the fundamentals determining quota prices we find that market activity is sufficiently high in the economically important markets and that price dispersion has decreased we also find evidence of economically rational behavior through the relationship between quota lease and sale prices and fishing output and input prices ecological variability and market interest rates controlling for these factors our results show a greater increase in quota prices for fish stocks that faced significant reductions consistent with increased profitability due to rationalization overall this suggests that these markets are operating reasonably well implying that itqs can be effective instruments for efficient fisheries management

how vulnerable is the emissions market to transaction costs an abms approach abstract the impact of transaction costs on the early emissions trading market is examined by applying an agent based model and simulation abms approach for a realistic model set up bounded rationality stochastic characteristics and learning by doing are considered in our search processes marginal abatement cost parameters are obtained from yoo et al 2010 which is an experimental study on the emissions trading in the korean power sector sensitivity analyses are performed on market performance indices with regard to transaction cost parameters which represent scales and the learning elasticities of transaction costs a total of 960 simulations were run in this sensitivity analysis sensitivity analysis results consistently show that higher transaction costs worsen market performance the most remarkable finding in these results is that welfare performance of all the transactions decreases by up to 50 as the scale parameters of transaction costs increase implying that welfare gain from introducing emissions trading disappears significantly however with learning curve effect welfare performance could be regained by up to 26 in sum although transaction costs significantly encroach upon trade gains at the early stage based on our simulation results the welfare loss by way of transaction costs is lessened as the knowledge of market participants progresses

sequestration offsets versus direct emission reductions consideration of environmental co effects abstract atmospheric greenhouse gas accumulation and consequential temperature increase can be remedied by emission reductions or agricultural carbon sequestration both options have direct and external environmental effects this paper examines the magnitudes of existing estimates of corresponding external co effects and how they could affect optimal combination of emission reductions and agricultural carbon sequestration we discuss whether government intervention in the form of taxation subsidization is justified for internalizing the externalities considering their relative magnitudes implementation costs and potential benefits that could be derived from such intervention we conclude that the existing estimates of external benefits from sequestration and emission reduction do not provide enough support for allocating resources to alter the market mix of carbon sequestration and direct emission reduction strategies

what do emissions markets deliver and to whom evidence from southern california s nox trading program a perceived advantage of cap and trade programs over more prescriptive environmental regulation is that enhanced compliance flexibility and cost effectiveness can make more stringent emissions reductions politically feasible however increased compliance flexibility can also result in an inequitable distribution of pollution we investigate these issues in the context of southern california s reclaim program we match facilities in reclaim with similar california facilities also located in non attainment areas our results indicate that emissions fell approximately 24 percent on average at reclaim facilities relative to our counterfactual furthermore we find that observed changes in emissions do not vary significantly with neighborhood demographic characteristics

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

do transaction costs influence firm trading behaviour in the european emissions trading system this study is one of the first to empirically investigate firm trading behaviour and the importance of permit trading transaction costs such as information costs and search costs in the first phase of the european union s emissions trading system eu ets the signs and significance of our constructed transaction costs proxy variables indicate for a presence of these costs in the initial years of the eu ets in particular this paper shows that ets firms with the smaller number of installations and with less trading experience were less likely to participate in the european emissions trading market and traded the lower quantities of permits furthermore these firms chose to trade permits indirectly via third parties this study also supports the concerns that transaction costs could be excessive for smaller participants and firms operating in the new eu member states

comparative economic analysis of supporting policies for residential solar pv in the united states solar renewable energy credit srec potential numerous studies and market reports suggest that the solar photovoltaic markets rely heavily if not entirely upon governmental support policies at present unlike in other countries where these policies are enacted at a national level the 50 states in the us pursue different policies in an attempt to foster the growth of renewable energy and specifically solar photovoltaics this paper provides an economic and financial analysis of the us federal and state level policies in states with solar targeted policies that have solar renewable energy credits srec markets after putting a value on srecs this study further compares solar carve outs with other incentives including the federal tax credit net metering and state personal tax credits our findings show that srec markets can certainly be strong with new jersey delaware and massachusetts having the most potential despite their strong potential as effective renewable policies the lack of a guaranteed minimum and the uncertainty attached are major drawbacks of srec markets however the leveraging of this high value offers hope that the policies will indeed stimulate residential solar photovoltaic markets

an experimental investigation of the seller incentives in the epas emission trading auction the clean air act requires the epa to conduct annual auctions of emission allowances under the discriminative auction rules sellers with the lowest asking prices receive the highest bids this paper studies an inverted version of this auction in which buyers face the same incentives as sellers in the epa auction consistent with theoretical predictions buyers bid above their valuation auction outcomes are inefficient and increasing the number of buyers increases bids buyers facing human opponents compete more aggressively than the risk neutral prediction but bids do not differ systematically from this prediction when buyers face computerized nash robots copyright 1995 by american economic association

fuzzy inductive reasoning expectation formation and the behavior of security prices abstract this paper extends the santa fe artificial stock market model sfasm studied by lebaron arthur and palmer 1999 journal of economic dynamics and control 23 1487 1516 in two important directions first some might question whether it is reasonable to assume that traders are capable of handling a large number of rules each with numerous conditions as is assumed in the sfasm we demonstrate that similar results can be obtained even after severely limiting the reasoning process we show this by allowing agents the ability to compress information into a few fuzzy notions which they can in turn process and analyze with fuzzy logic second lebaron et al have reported that the kurtosis of their simulated stock returns is too small as compared to real data we demonstrate that with a minor modification to how traders go about deciding which of their prediction rules to rely on when making demand decisions the model can in fact produce return kurtosis that is comparable to that of actual returns data

uncertain health and survival effects on end of life consumption this article analyzes the impact of health and survival uncertainty on the saving and consumption decisions of retirees a dynamic programming approach is used to model the household s planning problem the utility parameters are estimated using panel data we find that a fall into poor health raises the marginal utility from consumption simulations are used to indicate the effects of falling into poor health and loss of spouse they reveal a large transfer from the healthy to the sick partner and a strong dependence of saving on the survivor benefits suggesting that concern about the surviving spouse is an important motive for saving

weighted congestion games with separable preferences abstract players in a congestion game may differ from one another in their intrinsic preferences e g the benefit they get from using a specific resource their contribution to congestion or both in many cases of interest intrinsic preferences and the negative effect of congestion are additively or multiplicatively separable this paper considers the implications of separability for the existence of pure strategy nash equilibrium and the prospects of spontaneous convergence to equilibrium it is shown that these properties may or may not be guaranteed depending on the exact nature of player heterogeneity

genetic algorithms and inflationary economies abstract this paper studies overlapping generations economies in which agents use genetic algorithms to learn correct decision rules the results of computer simulations show that a genetic algorithm converges to the unique monetary steady state in case of a constant money supply policy and to the low inflation stationary equilibrium in case of a constant real deficit financed through seignorage features of the genetic algorithm adaptation are compared to the performance of other learning algorithms and to the behavior observed in experiments with human subjects in the same olg environments

on the existence of a pure strategy nash equilibrium in group formation games abstract this paper provides sufficient conditions for the existence of pure strategy nash equilibrium in a class of games of group formation the use of potentials allows for a characterization of such an equilibrium

designing more efficient markets lessons from los angeles smog control market based approaches for environmental protection are beginning to take root around the world this article attempts to improve our understanding of the performance of environmental markets by constructing and evaluating an information base on trades in los angeles which includes the first detailed data on trading prices the analysis suggests that trading activity has been shaped by the detailed regulations governing the market in addition transaction costs have played a crucial role we argue that the move toward adopting market based approaches for environmental protection needs to be accompanied by a vigorous effort to assess the properties of these systems as they are actually implemented

multi agent simulations to explore rules for rural credit in a highland farming community of northern thailand thanks to recent advances in the field of distributed artificial intelligence agentbased models abm can now be used to run simulations of social phenomena based on their computerized representations and to apply experimental methods in social sciences axelrod 1997 gilbert and troitzsch 1999 jager 2000 in the field of renewable resource management and environmental sciences several abm simulation platforms offer the possibility to explore interactions between social and ecological dynamics costanza and ruth 1998 bousquet et al 1998 lansing 2002 in these complex systems the social and economic dynamics can be viewed as a set of interactions among heterogeneous agents generating aggregate phenomena that are different from the behaviour of groups of average individuals considered in classical economic thinking rouchier and bousquet 1998 such a view was adopted in the research presented here

crises and confidence systemic banking crises and depositor behavior abstract we show that individuals who have experienced a systemic banking crisis are 11 percentage points less likely to use banks in the u s than otherwise similar individuals who emigrated from the same country but did not live through a crisis this finding is robust to controlling for exposure to other macroeconomic events and to various methods for addressing potential bias due to migrant self selection consistent with the view that personal experience plays an important role in decision making the effects are larger for individuals who were older and more likely to have had wealth entrusted to the banking system at the time of the crisis and for people who experienced crises in countries without deposit insurance

distributing pollution rights in cap and trade programs are outcomes independent of allocation standard economic theory predicts that if property rights to pollute are clearly established equilibrium outcomes in an efficient emissions permit market will be independent of how the emissions permits are initially distributed this so called independence property has important implications for policy design and implementation past studies document a strong positive correlation between the initial permit allocation and firm level emissions raising concerns that the independence property is failing to hold in real world settings we exploit the random assignment of firms to different permit allocation cycles in southern california s reclaim program in order to test the independence of permit allocation and emissions our results lend empirical support to the independence hypothesis

a tale of two water markets in australia lessons for understanding participation in formal water markets water markets are promoted as a demand management strategy for addressing water scarcity although there is an increasing literature on the institutional preconditions required for successful formal water markets there has been less focus on understanding what drives participation after establishment of the basic enabling conditions participation can be measured in terms of either trading activity conducting either a permanent or temporary water trade and or trade volumes across time and market products australia s water markets in the southern and northern basins of the murray darling basin provide a notable example of a tale of two water markets offering insights about the economic policy levers that can drive participation across different hydrological irrigation and socioeconomic contexts key lessons include distribution of initial property rights in resource allocation the need to prepare for and seize opportunities to strengthen property rights and robust monitoring and compliance requirements all of which will reduce transaction costs and increase participation
