green market expansion by reducing information asymmetries evidence for labeled organic food products abstract we investigate how the provision of objective information about the environmental and health impact of organic labels by policy makers can influence the willingness to pay of consumers for labeled organic apples in flanders belgium using a stated choice experiment we initially find that flemish consumers are willing to pay a positive price premium of some 33 eurocent per kilogram for labeled organic apples after the provision of information on the actual environmental and health effects of organic apple production this price premium becomes even more pronounced and increases to 57 eurocent per kilogram using a conditional logit model with covariates and a mixed logit model we find evidence of preference heterogeneity also the effect of information provision is more pronounced for certain groups of consumers such as non vegetarians infrequent buyers of organic products and members of a nature protection organization as such this paper illustrates that there is a role for policy makers and csr producers in providing more accurate and reliable information about socially responsible production processes moreover it is important to take the observed preference heterogeneity into account and tailor policies to specific consumer groups

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

optimal execution with regime switching market resilience abstract in this paper we study the optimal placement of market orders in a limit order book lob market when the market resilience rate which is the rate at which market replenishes itself after each trade is stochastic more specifically we establish a tractable extension to the optimal execution model in obizhaeva and wang 2013 by modelling the dynamics of the resilience rate to be driven by a markov chain when the lob replenishes itself stochastically through time the optimal execution strategy becomes state dependent and is driven linearly by the current remaining position and the current temporary price impact with their linear dependence based on the expectation of the dynamics of future resilience rate a trader would optimally place more aggressive respectively conservative market orders when the limit order book switches from a low to a high resilience state respectively from a high to a low resilience state our cost saving analysis indicates that the incremental execution costs can be substantial when the agent ignores the stochastic dynamics of the market resilience rate by adopting the state independent strategies

heterogeneity in preferences for woody biomass energy in the us mountain west abstract millions of acres of public forest in the us mountain west are substantially degraded and are in need of restoration mechanized restoration treatments can improve forest health and reduce the likelihood of severe wildfire these treatments produce some timber and substantial amounts of forest residues that can be used to generate renewable energy and displace fossil fuels using the choice modeling method this study investigates social preferences for generation of energy with woody biomass produced by restoration treatments on public forests in the mountain west both multinomial logit and latent class logit lcl models are fit to the data and used to estimate marginal willingness to pay mwtp for increased amounts of woody biomass energy generation and important associated co benefits and costs positive and statistically significant mwtp is found for the number of homes powered with wood the extent of healthy forests avoiding increases in the number of large wildfires and local air quality significant heterogeneity was found in respondent preferences for the attributes the heterogeneity can be explained in part by sociodemographic and attitudinal characteristics of respondents the lcl revealed four classes of respondents with distinct preferences revealing conflicting viewpoints toward forest management for woody biomass energy generation

assessing the impact of renewable energy deployment on local sustainability towards a theoretical framework renewable energy sources res have a large potential to contribute to the sustainable development sd of specific territories by providing them with a wide variety of socioeconomic and environmental benefits however the existing literature has put much emphasis on the environmental benefits including the reduction of global and local pollutants while socioeconomic impacts have not received a comparable attention these include diversification of energy supply enhanced regional and rural development opportunities creation of a domestic industry and employment opportunities with the exception of the diversification and security of energy supply these benefits have usually been mentioned but their analysis has been too general i e mostly at the national level and a focus on the regional and even more so the local level has been lacking at most studies provide scattered evidence of some of those regional and local benefits but without an integrated conceptual framework to analyse them this paper tries to make a contribution in this regard by developing an integrated theoretical framework which allows a comprehensive analysis of the impact of renewable energy on local sustainability and which can be empirically applied to identify these benefits in different territories

renewables portfolio individual preferences and social values towards res technologies abstract the massive deployment of renewable energy sources represents a high priority for greece in order to comply with the directive 2009 28 ec on the promotion of the use of energy from renewable sources by 2020 in this perspective aegean islands especially lesvos are endowed with a considerable potential of a portfolio of renewables a fact that the entrepreneurial interest has already been targeted however regulatory attempts for a massive penetration of renewables do not take seriously into account preferences and risk perceptions of local communities where the proposed projects are to be installed the aim of this study is to investigate individual preferences and social values towards specific technologies of renewables in lesvos island we apply an open ended contingent valuation survey in order to analyze factors shaping public attitudes towards a portfolio of renewable technologies and estimate the economic welfare willingness to pay of the preferred technologies we argue that such information is relevant for energy policy design and the establishment of effective measures for the promotion of renewable energy sources

accounting for local impacts of photovoltaic farms the application of two stated preferences approaches to a case study in portugal abstract renewable energy sources for electricity generation are unequivocally more environmentally friendly than the traditional sources but are not impact free given the potential for solar photovoltaic energy to contribute to the energy mix in some countries it is timely to carefully consider the potential environmental costs of operation of photovoltaic farms which are experienced by the local population while the general benefits accrue to all we apply the contingent valuation method to a sample of local residents close to three selected photovoltaic farms in portugal also we design a discrete choice experiment to elicit the valuation of specific adverse impacts of electricity generation through photovoltaic energy by national residents our results show that the value elicited in the vicinity of the photovoltaic farms is non negligible on the other hand national residents ponder the trade offs implied by the choice sets and value positively the different adverse local impacts both of these estimates in conjunction or independently can be used to fully account for this often neglected cost of solar energy furthermore we argue that when studying the public acceptance of renewables using stated preference methods explicitly presents the trade offs between negative impacts and costs contributing to more realistic portrayal of public opinion

analysing future trends of renewable electricity in the eu in a low carbon context the aim of this paper is to analyse the situation and trends of electricity from renewable energy sources res e in the eu up to 2030 taking into account several drivers and barriers and different maturity levels for the renewable energy technologies the methodology is based on the results of simulation models providing insights on future outlooks complemented with an analysis of regulations and other drivers and barriers regarding the most mature renewable electricity technologies the main drivers will be public policies carbon prices and support schemes and the expected up ward trend in fossil fuel prices and the main barriers are related to grid access administrative procedures and the exhaustion of places with the best wind resource for those already commercial but expensive technologies the main driver is support schemes but not carbon prices allowing the exploitation of the large potential for investment cost reductions barriers are mostly related to their high investment costs finally for those technologies which are emerging and immature further technical improvements as a result of r d efforts will be needed and they cannot be expected to significantly penetrate the european electricity market until 2030

publics knowledge attitudes and behavioral toward the use of solar energy in yemen power sector abstract this paper presents the information of the public s views on the solar energy use in yemen it examines the public knowledge of attitudes and behavioral intentions that include the variables willingness to pay willingness to change and willingness to invest and then compare them a personal interview with 348 urban household and 258 rural household was performed the descriptive statistics chi square for independence odds ratios mann whitney and kruskal wallis tests were the statistical tools employed in the analysis the results showed that the citizens in both areas have a moderate level of knowledge about renewable energy resources the benefits and drawbacks of solar energy use in the power sector and the solar power technologies despite that they have highly positive attitudes towards the use of renewable energy particularly solar energy and its technologies they also accept to engage in the renewable energy activities which aim to improve the quality of the electrical service provided in the country the findings also indicate 66 55 7 and 78 4 of urban citizens are willing to pay to change and to invest compared to 70 55 4 and 75 6 of rural citizens the place of residence factor affected significantly the citizens knowledge level about renewable energy wind biomass and geothermal energy renewable energy resources the drawbacks of solar energy use in the power sector and the solar power technologies it also affected significantly the citizens attitudes towards the use of solar power technologies at home the implications for the policymakers are that elevating the knowledge and awareness of the citizens by formal and informal education and enacting effective supportive policies assists in encouraging the citizens to use renewable energies in their daily lives would lead to achieve the country s renewable energy targets for 2025

residential willingness to pay for deep decarbonization of electricity supply contingent valuation evidence from hong kong abstract motivated by the government s proposed target of reducing co2 emissions by 30 of the 2005 level in the year 2020 we estimate the residential willingness to pay wtp for deep decarbonization of hong kong s electricity supply which is heavily dependent on coal fired generation our contingent valuation survey conducted in 2016 of 1460 households yields dichotomous choice data based on the respondents answers to a series of closed ended questions such data are less susceptible to the strategic bias that often plagues self stated wtp data obtained by direct elicitation via open ended questions using binary choice models we find that average wtp is 48 51 relative to current bills if the decarbonization target is achieved via natural gas generation and renewable energy however estimated wtp declines to 32 42 when decarbonization entails additional nuclear imports from china as the projected bill increase caused by the target s implementation is 40 our wtp estimates support the government s fuel mix policy of using natural gas and renewable energy to displace hong kong s coal generation

wind farm externalities and public preferences for community consultation in ireland a discrete choice experiments approach abstract in ireland the deployment of onshore wind turbines has become progressively more difficult in some areas because of the potential negative externalities associated with their operation using a discrete choice experiment dce we employ a willingness to accept framework to estimate the external effects of wind turbines on local residents with the inclusion of community consultation and to quantify the compensation required to permit wind farms to be built in ireland our findings reveal that the majority of respondents are willing to make monetary tradeoffs to allow for wind power initiatives and we find that respondents require less compensation if provision is made for a community representative and setback distance is increased

learning information processing and order submission in limit order markets by introducing a genetic algorithm learning with a classifier system into a limit order market this paper provides a unified framework of microstructure and agent based models of limit order markets that allows traders to determine their order submission endogenously according to market conditions it examines how traders process and learn from market information and how the learning affects limit order markets it is found that measured by the average usage of different group of market information trading rules under the learning become stationary in the long run also informed traders pay more attention to the last transaction sign while uninformed traders pay more attention to technical rules learning of uninformed traders improves market information efficiency but not necessarily when informed traders learn opposite to the learning of informed traders learning makes uninformed traders submit less aggressive limit orders and more market orders furthermore private values can have significant impact in the short run but not in the long run one implication is that the probability of informed trading pin is positively related to the volatility and the bid ask spread

backward and forward looking shadow prices in inclusive wealth accounting an example of renewable energy capital abstract attaching weights to the list of capital assets is crucial in inclusive wealth accounting and sustainability assessments these weights or shadow prices can be constructed in theory by looking prospectively at future social profits that the capital in question is expected to yield in practice however both backward and forward looking shadow prices are used this study confirms that these two approaches are theoretically equivalent under strong assumptions and reviews how and why the two approaches are taken the two approaches are then applied to renewable energy capital rec which has rarely been done in either produced or natural capital accounting and sustainability assessments renewable energy capital provides an ideal example with which to compare the two approaches as it is a class of produced capital that substitutes both produced and natural capital the numerical results of both approaches demonstrate that renewable energy capital starts to account for as large a share as natural capital does if not produced capital or inclusive wealth in those countries where natural capital is poorly endowed and investment in renewable energy capital has been witnessed

valuation of environmental and societal trade offs of renewable energy sources abstract use of renewable energy sources is one solution to decrease green house gas emissions and the use of polluting fossil fuels renewables differ in their environmental and societal impacts and to design sound renewable energy policy societies need to assess the trade offs between alternative sources to enable the evaluation and comparison of renewable energy production alternatives in finland this paper applies the choice experiment to elicit the monetary information on people s preferences for four renewable energy sources wind power hydro power and energy from crops and wood and considers four impacts of energy production effects on biodiversity local jobs carbon emissions and household s electricity bill the nested logit analysis reveals that higher income male gender young age and pro environmental attitude increase the probability to choose renewable energy instead of the current energy mix wind power is on average the most popular renewable energy technology but regional differences exist biodiversity deterioration should be avoided the national aggregate willingness to pay based on stated preferences rather than preferences revealed by actual market behavior for a combination of renewable energy technologies that corresponds to finland s climate change and energy policy is over 500 million euros

willingness to pay for ancillary benefits of climate change mitigation assessing the willingness to pay wtp of the general public for climate change mitigation programmes enables governments to understand how much taxpayers are willing to support the implementation of such programs this paper contributes to the literature on the wtp for climate change mitigation programmes by investigating in addition to global benefits the ancillary benefits of climate change mitigation it does so by considering local and personal benefits arising from climate change policies the contingent valuation method is used to elicit the wtp for ancillary and global benefits of climate mitigation policies in the basque country spain results show that wtp estimates are 53 73 higher when ancillary benefits are considered

limit orders depth and volatility evidence from the stock exchange of hong kong we investigate the role of limit orders in the liquidity provision in a pure orderdriven market results show that market depth rises subsequent to an increase in transitory volatility and transitory volatility declines subsequent to an increase in market depth we also examine how transitory volatility affects the mix between limit orders and market orders when transitory volatility arises from the ask bid side investors will submit more limit sell buy orders than market sell buy orders this result is consistent with the existence of limit order traders who enter the market and place orders when liquidity is needed

the impact of foreign direct investment on new firm survival in the uk evidence for static versus dynamic industries the paper examines the impact of foreign direct investment fdi on the survival of business start ups fdi has potential for both negative displacement competition effects as well as positive knowledge spillover and linkage effects on new ventures we find a net positive effect for the whole dataset however a major contribution of the paper is to outline and test an argument that this effect is likely to be comprised of a net negative effect in dynamic industries high churn firm entry plus exit relative to the stock of firms alongside a net positive effect in static low churn industries we find evidence to support this view the results identify new effects of globalisation on enterprise development with associated challenges for industrial policy

valuing the visual impact of wind farms an application in south evia greece abstract this study presents an application of the contingent valuation method cvm for valuing the landscape externalities associated with the large scale exploitation of wind power at the local level the survey was undertaken in south evia greece which is a region with rich wind energy potential and a considerable number of wind farms in operation during the period of the study the results showed that 57 of the households are not willing to contribute financially in order to implement interventions to mitigate the visual impact of wind farms he mean willingness to pay per household to avoid the visual impact attributed to the installation of new wind farms in the area in question was estimated at 41 6 year taking into account all households of the sample this estimate is relatively lower compared to the results of other relevant studies as shown by a meta analysis developed based on these studies this is mainly attributed to the great recession in greece and the reduced available income of households

low energy efficiency in rental properties asymmetric information or low willingness to pay abstract asymmetric information may explain low energy efficiency in rented properties energy ratings while a solution to the information problem will only lead to higher efficiency levels if renter s willingness to pay wtp exceeds landlord s investment costs using a sample of renters from one university this paper estimates this wtp using a discrete choice experiment where respondents choose from a hypothetical set of single bedroom apartments that differ according to a number of attributes including the energy rating results show that there is a strong disutility associated with the least efficient properties and that renters will pay significantly more for efficiency improvements at the lower end of the efficiency scale importantly our wtp estimates are calculated in a setting where respondents were informed about the energy rating system prior to choosing and where the rating was shown for every property therefore in order to maximise the impact of energy rating systems policymakers are encouraged to ensure that both these informational characteristics are in place

random preferences towards bioenergy environmental externalities a case study of woody biomass based electricity in the southern united states article i nfo this paper contrasts alternate methodological approaches of investigating public preferences the random parameter logit rpl where tastes and preferences of respondents are assumed to be heterogeneous and the conditional logit cl approach where tastes and preferences remain fixed for individuals we conducted a choice experiment to assess preferences for woody biomass based electricity in arkansas florida and virginia reduction of co2 emissions and improvement of forest habitat by decreasing risk of wildfires and pest outbreaks were presented to respondents as attributes of using green electricity the results indicate that heterogeneous preferences might be a better fit for assessing preferences for green electricity all levels of both attributes were positive contributors to welfare but they were no statistically significant respondents expressed a positive mean marginal willingness to pay wtp for each attribute level the total wtp for green electricity per kilowatt hour was 0 049 kwh or 40 5 per capita year 1 when converted into future total annual expenditures

the spatial evolution of the british automobile industry does location matter this article aims to describe and explain the spatial evolution of the automobile sector in great britain from an evolutionary perspective this analysis is based on a unique database of all entries and exits in this sector during the period 1895 1968 collected by the authors cox regressions show that spinoff dynamics agglomeration economies and time of entry have had a significant effect on the survival rate of automobile firms during the period 1895 1968

new firm survival new results using a hazard function a limitation of audretsch s 1991 study of new firm survival was the level of aggregation to industries this precluded linking establishment specific characteristics such as organizational structure and size to post entry performance the purpose of this paper is to relate the post entry performance of individual establishments not only to their technological and market structure environments but also to establishment specific characteristics we do this by estimating a hazard duration function for more than 12 000 individual establishments in u s manufacturing started in 1976 by tracking their subsequent performance over a ten year period we conclude that establishment specific characteristics which audretsch was not able to capture in his earlier study play an important role in shaping the exposure to risk confronting new establishments copyright 1995 by mit press

using conjoint analysis to quantify public preferences over the environmental impacts of wind farms an example from spain this paper focuses on the effect on people s utility of the potential environmental impacts of wind farm developments we report on research designed to provide insight into their preferences and we show how two alternative choice modelling techniques can be used to estimate them our results show that significant social costs in the form of environmental impacts can be associated with wind farm developments as relative environmental values are revealed by these methods it would be possible to develop wind farms in such a way that minimises the total social costs of the investment and which maximises its net benefits

choice modelling approaches a superior alternative for environmental valuation in this paper we examine some popular choice modelling approaches to environmental valuation which can be considered as alternatives to more familiar valuation techniques based on stated preferences such as the contingent valuation method a number of choice modelling methods are consistent with consumer theory and its focus on an attribute based theory of value permits a superior representation of many environmental management contexts however choice modelling surveys can place a severe cognitive burden upon respondents and induce satisficing rather than maximising behavioural patterns in this framework we seek to identify the best available choice modelling alternative and investigate its potential to solve some of the major biases associated with standard contingent valuation we then discuss its use in the light of policy appraisal needs within the eu an application to the demand for rock climbing in scotland is provided as an illustration

a closer look at the effect of market growth on industries profits everybody talks about the relation of industries profit rates to their markets rates of growth but nobody does anything about it specifically researchers have confirmed the effect of the growth of nominal output on profits in many multivariate studies without specifying closely the hypothesis under test or the measure of demand growth appropriate to test it a profits growth relationship could stem from several mechanisms the lagged adaptation of capacity to unexpected changes in demand reactions of oligopolists to disturbances in their consensus etc these mechanisms how and where they work hold their own normative interest therefore knowing what behavior and what structure lying behind it accounts for the profits growth relationship should do more than improve the specifications of our studies of allocative efficiency it should also expand our knowledge of adaptive processes that are important and hard to observe directly in this paper we shall synthesize the available explanations of why changes in market demand should affect an industry s profits then present a statistical test of the relative significance of the competing explanations

what determines urban households willingness to pay for co2 emission reductions in turkey a contingent valuation survey abstract this paper explores turkish urban households willingness to pay wtp for co2 emission reductions expected to result from improvements in power production a face to face questionnaire with a contingent valuation cv module prepared using the double bounded dichotomous choice elicitation framework was administered to 2422 respondents representative of urban turkey a developing country with low but rapidly increasing greenhouse gas emissions the determinants of wtp were identified by considering not only the impact of standard socio economic factors but also the effects of environmental knowledge attitudes and behaviour the relevance of the identity of the collection agent national versus international institutions in terms of trust people have towards them and the degree of perceived participation of others in the realization of the project our study confirms the existing literature in demonstrating that wtp figures reported by young and educated people that are active on environmental issues and who also possess material security and environmental knowledge are more likely to be high however their willingness to make contributions is hampered significantly by their belief that their fellow citizens will not contribute and the general lack of trust in institutions overall this study may be taken as a call to eliminate governance related uncertainties in climate change deals

do agglomeration externalities affect firm survival abstractdo agglomeration externalities affect firm survival regional studies this paper analyses the impact of spatial agglomeration externalities on italian start up firms survival italy represents a relevant case study given the well known role of firm clusters in the country s economic development results obtained support the hypothesis that industry variety reduces the likelihood of firm exit specifically related variety which contributes to the generation and diffusion of new knowledge has a positive effect on firm survival in manufacturing sectors while unrelated variety which may work as a portfolio strategy plays a positive role in services sectors localization economies positively influence firm survival only in services sectors finally urban density is not robust to the control for firm characteristics

a latent class approach to investigating demand for genetically modified banana in uganda this study explores consumer acceptance and valuation of a genetically modified gm staple food crop in a developing country prior to its commercialization we focus on the hypothetical introduction of a disease resistant gm banana variety in uganda where bananas are among the most important staple crops a choice experiment is used to investigate consumer preferences for various attributes related to the banana such as bunch size technology producer benefit and price and examine their opinions on gm foodstuff choice data come from 421 banana consuming households randomly selected from three regions of uganda a latent class model is used to investigate the heterogeneity in consumers preferences for selected attributes related to the banana and to profile consumers who are more or less likely to accept gm bananas our results reveal that there is significant heterogeneity in consumer preferences across our sample gm bananas are valued the most by poorer households located in the rural areas of the eastern region these food insecure households would experience the highest benefits i e welfare gains from the commercial release of gm bananas in contrast urban consumers are less accepting of gm bananas and they would experience significant welfare losses if gm banana is released according to our welfare estimates both the total welfare benefits acquired by the gainers and the total welfare losses borne by the losers of this technology are significant and large these results suggest the need for further investigation of the overall welfare effects of the introduction of gm bananas on the ugandan society as a whole

dynamic trading policies with price impact abstract in this paper we analyze the optimal policy for a risk averse agent who wants to sell a large block of shares of a risky security in the presence of price impact and transactions costs our framework reduces to the standard merton portfolio problem in the absence of any market frictions optimal liquidation results in revenue distributions which are substantially different from those generated by a naive strategy the main tradeoff involves choosing between revenue distributions which have high means versus those which have low variances furthermore our results suggest that the effective liquidity of a security depends on its return distribution and on the characteristics of the agent carrying out the trade as well as on the price impact function

urban economic structure technological externalities and intensive land use in china based on theories about the influences of urban economic structure on intensive land use this study analyses the impacts of two main types of urban economic structure in china specialized economy and diversified economy on intensive urban land use using spatial panel techniques and large scale urban panel data the results indicate that there is significant spatial correlation in urban economic structure as well as intensive land use in every city a diversified economy has a significant positive effect on the improvement of intensive land use whereas the effect of a specialized economy is not significant the effects of the diversified and specialized economies on intensive land use through technological externalities are either negative or positive depending on city size while the threshold effect the minimum threshold population for the economy to stimulate intensive land use is about 496 700 people for the specialized economy and about 546 000 people for the diversified economy

spatial agglomeration and firm exit a spatial dynamic analysis for italian provinces the paper investigates the effect of spatial agglomeration on firm exit in a dynamic framework using a large dataset at the industry province level for italy 1998 2007 we estimate a spatial dynamic panel model via a gmm estimator and analyze the short run impact of specialization and variety on firm exit specialization negatively affects firm exit rates in the short run the effect is particularly significant for low tech firms the impact of variety on firm mortality rates at the industry level is instead less clear although still negative and significant for low tech firms

is specialization good for regional economic development kemeny t and storper m is specialization good for regional economic development regional studies debates about urban growth and change often centre on specialization however arguments linking specialization to metropolitan economic development contain diverse and sometimes conflicting claims is it better to be highly specialized or diversified does specialization refer to the absolute or relative scale of an activity in a region does specialization have static or evolutionary effects this paper investigates these questions in theoretical and empirical terms by analysing local agglomerations over time it is found that growing absolute specialization is positively linked to wages while changes in relative concentration are not significantly associated with wage dynamics

investment preferences for wood based energy initiatives in the us abstract the forest sector is poised to become a major supplier of wood based energy in the us prospects for growth in energy demand and higher prices can create opportunities for private investments in renewable energy industries a conjoint analysis examined individuals willingness to invest in wood based energies following a random utility model the study design included three investment attributes annual returns on investment type of investment and location of investment three ordinal models that also included demographic and attitudinal characteristics indicate that wood based energy is less preferred among potential investors compared to the stock market and solar wind renewable energy investments expected returns and location of energy investments within the us are also major drivers of investment preferences favorable attitudes towards forestry and wood based energy could enhance prospects for a greater number of potential investors

valuing climate protection through willingness to pay for biomass ethanol abstract this study uses a multi part split sample contingent valuation method cvm and fair share fs survey to better understand the public s valuation of mitigating global climate change through its willingness to pay for biomass or cellulosic ethanol in addition to a basic cvm question a related scenario was developed that asked half of the survey respondents to state their fair share cost to lessen a potential food shortage in the next decade also through the expanded use of cellulosic ethanol three alternative biomass feedstocks were assessed farming residues forestry residues and paper mill wastes and municipal solid wastes overall a slightly larger proportion of respondents were wtp extra for cellulosic ethanol in the basic cvm scenario than in the fs scenario though no significant differences were found in the wtp for the different feedstocks bid curve lognormal regression results for the two models were similar supporting the idea that asking a fs rather than a conventional wtp question may be justifiable in some circumstances such as in cases of a national emergency

multilevel approaches and the firm agglomeration ambiguity in economic growth studies empirical studies in spatial economics have shown that agglomeration economies may be a source of the uneven distribution of economic activities and economic growth across cities and regions both localization and urbanization economies are hypothesized to foster agglomeration and growth but recent meta analyses of this burgeoning body of empirical research show that the results are ambiguous recent overviews show that this ambiguity is fuelled by measurement issues and heterogeneity in terms of scale of time and space aggregation growth definitions and the functional form of the models applied alternatively in this paper we argue that ambiguity may be due to a lack of research on firm level performance in agglomerations this research is necessary because the theories that underlie agglomeration economies are microeconomic in nature hierarchical or multilevel modeling which allows micro levels and macro levels to be modeled simultaneously is becoming an increasingly common practice in the social sciences as illustrated by detailed dutch data on firm level productivity employment growth and firm survival we argue that these approaches are also suitable for reducing the ambiguity surrounding the agglomeration firm performance relationship and for addressing spatial sectoral and cross level heterogeneity

rural versus urban preferences for renewable energy developments development of renewable energy resources such as wind farms and hydro electric schemes are being promoted as a new method of expanding and diversifying employment in rural areas however such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities such as those based on nature tourism the authors use a choice experiment to quantify peoples preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of scotland focussing in particular on any differences between the preferences of urban and rural dwellers and on heterogeneity within these groups rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration

choice experiment study on the willingness to pay to improve electricity services abstract modern forms of energy are an important vehicle towards poverty alleviation in rural areas of developing countries most developing countries households rely heavily on wood fuel which impacts on their health and socio economic status to ease such a dependency other modern forms of energy namely electricity need to be provided however the quality of the electricity service namely reliability is an important factor in reducing this dependency this paper discusses a choice experiment valuation study conducted among electrified rural households located in kisumu kenya in which the willingness to pay wtp to avoid power outages or blackouts was estimated a mixed logit estimation was applied to identify the various socio economic and demographic characteristics which determine preferences in reducing power outages among a household s users in conclusion several of the socio economic and demographic characteristics outlined in this paper were identified and can assist service differentiation to accommodate the diverse households preferences towards the improvement of the electricity service
