large scale deployment of renewables for electricity generation comparisons of resource assessments suggest that sufficient renewable energy resources are available to allow for large scale deployment of renewable energy technologies economic analysis identifies barriers to the adoption of renewable energy sources resulting from i market structure ii competition in an uneven playing field and iii various non marketplace barriers however even if these barriers are removed the problem of technology lock out remains the key policy response is strategic deployment coupled with increased r d support to accelerate the pace of improvement through market experience this paper suggests significant contributions from various technologies are possible but does not assess their optimal or maximal market share copyright 2005 oxford university press

the renewables portfolio standard in texas an early assessment texas has rapidly emerged as one of the leading wind power markets in the united states this development can be largely traced to a well designed and carefully implemented renewables portfolio standard rps the rps is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation though replacing existing renewable energy policies with an as of yet untested approach in the rps is risky early experience from texas suggests that an rps can effectively spur renewables development and encourage competition among renewable energy producers initial rps targets in texas were well exceeded by the end of 2001 with 915 mw of wind installed in that year alone rps compliance costs appear negligible with new wind projects reportedly contracted for well under 3 us cent k wh in part as a result of a 1 7 us cent kwh production tax credit an outstanding wind resource and an rps that is sizable enough to drive project economies of scale obliged retail suppliers have been willing to enter into long term contracts with renewable generators reducing important risks for both the developer and the retail supplier finally the country s first comprehensive renewable energy certificate program has been put into place to monitor and track rps compliance c 2002 published by elsevier science ltd less

an analysis of feed in tariff remuneration models implications for renewable energy investment recent experience from around the world suggests that feed in tariffs fits are the most effective policy to encourage the rapid and sustained deployment of renewable energy there are several different ways to structure a fit policy each with its own strengths and weaknesses this paper presents an overview of seven different ways to structure the remuneration of a fit policy divided into two broad categories those in which remuneration is dependent on the electricity price and those that remain independent from it this paper examines the advantages and disadvantages of these different fit models and concludes with an analysis of these design options with a focus on their implications both for investors and for society

cost competitive incentives for wind energy development in china institutional dynamics and policy changes abstract this paper presents an overview of the development of wind power in china the factors that affect the directions of wind power development are analyzed it examines the economics of windfarm development and compares it with conventional energy sources the major constraints in wind technology development and defects of the current policies are discussed it points out that wind power development should be subject to rational policy change and institutional adjustment it discusses the incentive mechanisms and institutional frameworks for future development particular importance is attributed to market incentives for wind power to reach the objectives of industrialization and commercialization a number of cost competitive incentive measures and policies are recommended i introducing market based mechanisms through standard power purchase agreement ii establishing effective investment policies and regulations to attract private investment iii promoting localization of wind turbine production iv adjusting tax and subsidy policies and v reforming governmental institutions to make clear rules and responsibilities for policymaking and enhancing communication coordination between relevant government agencies in order to formulate uniform and effective policies

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

determinants of donations in private nonprofit markets abstract we estimate the responsiveness of donations to a number of economic variables including price advertising and the availability of revenue from such other sources as government grants and program service sales utilizing a set of irs data on individual nonprofit organizations in each of seven industries including hospitals and higher education for the years 1982 1994 we find distinct overall patterns as well as notable variation across industries a nonprofit organization s fundraising expenditures are estimated to exert two countervailing effects on donations the direct advertising and information effect augments donations while the indirect effect on the price of donating has a negative effect we do not find evidence that fundraising is carried to the profit maximizing levels in some industries fundraising is substantially short of that level while in other industries it is excessive implying that the marginal return to fundraising is exceeded by the cost focusing on whether revenue from other sources affects donations to a nonprofit organization we find evidence that revenue from either government grants or from the organization s own program sales activity generally does not crowd out private donations to the contrary in most industries there are significant positive effects

global wind power development economics and policies abstract existing literature indicates that theoretically the earth s wind energy supply potential significantly exceeds global energy demand yet only 2 3 of global electricity demand is currently derived from wind power despite 27 annual growth in wind generating capacity over the last 17 years more than 95 of total current wind power capacity is installed in the developed countries plus china and india our analysis shows that the economic competitiveness of wind power varies at wider range across countries or locations a climate change damage cost of us 20 tco 2 imposed to fossil fuels would make onshore wind competitive to all fossil fuels for power generation however the same would not happen to offshore wind with few exceptions even if the damage cost is increased to us 100 tco 2 to overcome a large number of technical financial institutional market and other barriers to wind power many countries have employed various policy instruments including capital subsidies tax incentives tradable energy certificates feed in tariffs grid access guarantees and mandatory standards besides climate change mitigation policies such as the clean development mechanism have played a pivotal role in promoting wind power despite these policies intermittency the main technical constraint could remain as the major challenge to the future growth of wind power

public policy supports and export performance of bioenergy technologies a dynamic panel approach abstract this study investigates the effects of public policy supports on the export performance of bioenergy technologies it uses panel data from 18 countries from the 1992 to 2008 period panel unit root and cointegration tests are applied taking into account the results of structural break tests for each time series and testing for the presence in the panel of cross sectional dependence time series data on public supports and exports are integrated and cointegrated the results of dynamic ordinary least squares indicate that in the long term public r d expenditures have a positive effect on the exports the contribution of bioenergy to the total energy supply has a negative effect on the exports and gdp has a positive effect on the exports the contribution of bioenergy to total energy supply responds to deviations in the previous period from the long term equilibrium additionally blundell bond system generalized methods of moments estimations are made to determine dynamic causality in a panel vector error correction mechanism setting evidence of a positive strong and short term relationship from exports to r d expenditures and of a positive short term causality from exports to the contribution of bioenergy to total energy supply is found a positive strong bidirectional relationship between gdp and exports is also uncovered there is a positive strong bidirectional and short term relationship between gdp and the contribution of bioenergy to total energy supply finally some policy implications based on the results of this study are offered

government funded renewable energy innovation in china abstract with the rapid development of the economy china is facing pressures caused by traditional energy deficiency and environmental pollution in recent years which has forced the chinese government to start to pay attention to the development and utilization of renewable energy re this article based on data and statistics available up to 2008 studies features of china s re technology innovation and problems thereof it finds that national science and technology programs are the main aspect of china s re technology innovation and most of r d funds for the re technology come from china s three main national programs besides the overall expenditures on re technology innovation constitute only a small proportion of china s total domestic r d funding and seem not enough this paper also finds that compared with research and development stages of re technology the demonstration and diffusion of re technology in china are given less attention and thus are relatively less sufficient furthermore influenced by china s traditional scientific research system there appears lack of sufficient incentives and opportunities for private sectors to fully participate in re technology innovation because most national programs are undertaken by universities or research institutes

the role of transnational dimensions in emerging economy technological innovation systems for clean tech the technological innovation system tis framework and its system functions have become a popular analytical tool for the study of clean tech innovation there is increasing attention for the role of emerging economies in global clean tech innovation but the applicability of tis to emerging economies cases is not entirely straightforward a key issue is the limited geographical considerations in particular transnational dimensions in tis whereas earlier perspectives on innovation in emerging economies have stressed the role of such transnational dimensions this paper elaborates transnational tis actor networks and institutions categorizes these in relation to tis functions and describes their potential to induce or block tis development in emerging economies we draw on insights from the perspectives of national learning systems international technology transfer and global production networks for this purpose we conclude that the potential effects of these transnational dimensions may be accurately grasped by the existing list of system functions lending credence to its further application of the tis framework on emerging economy case studies policy makers in emerging economies should recognize these transnational dimensions and seek to optimize their potential effect on domestic tis development taking in to consideration a realistic assessment of its role in the global tis

weighing what s practical proxy means tests for targeting food subsidies in egypt abstract despite achieving a significant cost reduction over the past two decades the absolute cost of food subsidies in egypt is still high relative to the benefits received by the poor there is scope for better targeting these food subsidies in particular for targeting cooking oil and sugar ration cards both because reforms in this area are perceived to be far less politically sensitive than adjusting subsidy policy for bread and wheat flour and because higher income groups presently receive a significant percentage of the benefits targeting the high subsidy green ration cards to the poor and the low subsidy red ration cards to the nonpoor will require identification of both poor and nonpoor households an international food policy research institute research team in egypt in collaboration with the egyptian ministry of trade and supply developed a proxy means test for targeting ration cards the paper describes the process of moving from the optimal income predicting model to the final model that was both administratively and politically feasible an ex ante evaluation of the levels of accuracy of the proxy means testing model indicates that the model performs quite well in predicting the needy and nonneedy households an effective and full implementation of this targeting method would increase the equity in the ration card food subsidy system and at the same time the total budgetary costs of rationed food subsidies would decline moreover the experience gained under this reform would facilitate targeting future social interventions to reduce and prevent poverty in egypt

towards improved policy processes for promoting innovation in renewable electricity technologies in the uk this paper analyses recent current and potential future relations between policy processes and substantive outcomes in uk low carbon innovation policy focussing on policies relating to renewable electricity generation technologies it examines the development of policy processes relating to the adoption and implementation of the renewables obligation and how these may affect the current and likely future success of the obligation in promoting low carbon innovation it examines the new policy and institutional processes put in place in the 2003 energy white paper and argues that these are unlikely to provide the strategic long term framework needed to realise the ambitious goals for uk energy policy set out in the white paper finally it outlines some suggestions for further development of policy processes to facilitate improved delivery of these goals based on guiding principles for sustainable innovation policy processes developed by the authors and their colleagues

germany s solar cell promotion dark clouds on the horizon abstract this article demonstrates that the large feed in tariffs currently guaranteed for solar electricity in germany constitute a subsidization regime that threatens to reach a level comparable to that of german hard coal production a notoriously outstanding example of misguided political intervention yet as a consequence of the coexistence of the german renewable energy sources act eeg and the eu emissions trading scheme ets the increased use of renewable energy technologies does not imply any additional emission reductions beyond those already achieved by ets alone similarly disappointing is the net employment balance which is likely to be negative if one takes into account the opportunity cost of this form of solar photovoltaic pv support along the lines of the international energy agency iea 2007 energy policies of iea countries germany 2007 review international energy agency oecd paris p 77 we recommend the immediate and drastic reduction of the magnitude of the feed in tariffs granted for solar based electricity ultimately producing electricity on this basis is among the most expensive greenhouse gas abatement options

financial incentives to mobilise local citizens as investors in low carbon technologies a systematic literature review abstract mobilising greater levels of private finance through local citizen investment in low carbon technologies can help bridge the capital shortfall to meeting climate objectives while also building societal support for the low carbon transition within this context we undertake a systematic review of literature assessing the impact of technology specific economic and financial incentives promoting greater levels of investment in low carbon technologies from local citizen investors both individuals and community groups we focus in particular on the impact of feed in tariffs compared to quota schemes grants tax incentives and soft loans the analysis suggests that local citizen investors do not necessarily act in an economically rational manner in response to these incentives it underscores the importance of understanding the preferences of target demographics the local context as well as the characteristics of the technologies in question and suggests interventions should be considered as part of wider policy packages while identifying challenges to be overcome through instrument design we find that feed in tariffs grants and tax incentives can be successful in mobilising greater levels of investment from local citizen investors but that soft loans tend to be less effective as a stand alone instrument the review identifies areas meriting further exploration in this emerging field of research

prospects for global market expansion of china s wind turbine manufacturing industry abstract emerging economies are increasingly contributing to global innovation including clean tech innovation the development of china s wind power sector has often been used to illustrate this point china s domestic wind power market is the largest in the world and is largely supplied by domestic manufacturers competition for market share in the domestic market may pressure firms to innovate which consecutively improves prospects for global expansion this paper reviews developments in china s domestic wind turbine market using the technological innovation system framework we analyze the pressure to innovate arising from market competition and assess the prospects for global expansion of chinese wind turbine manufacturers we conclude that domestic customers are not pressured or incentivized to perform with respect to power output such that turbine manufacturers are not pressured to perform with respect to turbine efficiency or maintenance needs pressure to innovate is further reduced by formalizing connections between wind farm developers and turbine manufacturers chinese turbine manufacturers cannot yet compete with leading global brands in technological leadership the prospects for exports are improved however by the preferential supply of project financing from institutional investors such as the china development bank from chinese utilities that seek global expansion and from the manufacturers themselves

regulatory design for res e support mechanisms learning curves market structure and burden sharing drawing from relevant experiences in power systems around the world this paper offers a review of existing policy support mechanisms for res e with a detailed analysis of their regulatory implications while recent studies provide an account of current res e support systems in this paper we focus on some of the impacts these mechanisms have on the overall energy market structure and its performance given the rising importance of res e in systems everywhere these impacts should no longer be overlooked

can fao s measure of chronic undernourishment be strengthened abstract in its sixth world food survey released at the 1996 world food summit the food and agriculture organization of the united nations fao reported that 841 million people in developing countries are chronically undernourished this number and its country and regional level disaggregations have proved tremendously useful to countless development aid agencies and researchers in the context of a recent wave of new nationally representative household food consumption and expenditure surveys this paper examines the estimation methodology underlying the food insecurity measure which relies on national aggregate measures of food availability and distribution the paper finds that the measure largely reflects national food availabilities and does not adequately capture people s ability to gain access to food the ultimate key to food security the implications for the indicator s use by policy makers in geographical targeting and tracking changes in food insecurity over time are drawn out the paper concludes by arguing that the time has come to review the potential for employing the new household survey data along with new methods to strengthen the empirical foundations of fao s measure

a methodology for measuring food poverty applied to kenya abstract this paper proposes a new way of establishing a food poverty line taking into account regional food preferences and prices it uses this poverty line to derive a food poverty measure which satisfies the desirable fundamental properties of such measures and has the additional advantage of being additively decomposable the measurement of food poverty is further generalized to heterogeneous groups of households facing different sets of relative prices and exhibiting different food preferences finally the above methodology is applied to the empirical estimation of food poverty among kenyan smallholders and the results contrasted with those obtained by two other methods

demand pull technology push and government led incentives for non incremental technical change abstract rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations how well does this notion of demand pull apply to non incremental technological change when demand is largely attributable to actions by governments in this case inventors of the most important inventions did not respond positively to strong demand pull policies filing of highly cited patents declined precipitously just as demand for wind power created a multi billion dollar market three explanations for this apparent inconsistency with the demand pull hypothesis played a role 1 the rapid convergence on a single dominant design limited the market opportunity for non incremental technical improvements 2 even though the policies implemented were stringent enough to stimulate demand uncertainty in their longevity dampened the incentives for inventions that were likely to take several years to pay off and 3 alternative explanations such as declining r d funding and weakening presidential engagement on energy appear to have been important

electricity prices and industrial competitiveness a case study of final assembly automobile manufacturing in the united states and canada this paper studies the real and perceived impacts of electricity pricing on competitiveness in the united states and canada financial analysis is combined with interviews to explore whether and how the cost of electricity affects competitiveness in one of north america s most important sectors automobile manufacturing the cost of electricity in top automobile manufacturing jurisdictions in canada and the us is captured over a six year period starting in 2010 at between approximately us 2 00 and 11 00 per vehicle the paper finds that the per vehicle gap between electricity costs in the most expensive automobile making jurisdiction in north america ontario and all others is quite small how then to explain the preoccupation of industry actors with electricity costs in ontario several reasons are suggested including media coverage the relatively narrow inventory of issues under local management control and mechanics of the pricing system itself the paper explains how the pricing system causes manufacturers to make decisions that depart from core mandates making things and generates the unintended effect of heightened scrutiny a combination of factors that has the effect of aggravating tension around electricity pricing and damaging perceived competitiveness

the uk s levy control framework for renewable electricity support effects and significance there is a long standing debate over price vs quantity approaches to supporting the deployment of renewable electricity technologies in the context of a a recent shift from quantity to price based support the uk has also introduced a new form of budgetary framework the levy control framework lcf the introduction of the lcf has been very important for investors but has received relatively little attention in the academic literature the paper gives an overview of the lcf explores its effects on renewables policy on consumers and on investor confidence arguing that an unintended consequence of its introduction has been to increase uncertainty through interactions with underlying support mechanisms a number of problems with the current scope and design of the lcf are noted it is argued that the lcf is best understood as aimed at avoiding a political backlash against renewable support policy in a context where the benefits of such policy are concentrated economically and socially the paper concludes by placing the lcf within a wider context of a shift towards greater budgetary control over renewable energy support policy across european countries

food energy intake and cost of basic needs measuring poverty in bangladesh past estimates of poverty in bangladesh based on the food energy intake method found decreasing poverty over time and similar poverty in urban and rural areas using the cost of basic needs method we find increasing poverty for 1984 92 and higher poverty in rural than urban areas examples of lack of consistency in past estimates are highlighted a method is introduced to assess the gap narrowing and re ranking impacts on poverty measures of changes in poverty lines the article also estimates the marginal impact of household characteristics such as household size education occupation and land ownership on the probability of being poor

local demand pull policy and energy innovation evidence from the solar photovoltaic market in china abstract market demand is an important driver for inducing innovation with many empirical studies supporting the demand induced innovation hypothesis critiques of such studies however emphasize that new empirical evidence that can address existing empirical challenges is needed furthermore existing literature disagrees about whether the locus of demand pull policy matters in this paper we use empirical evidence from the distributed solar photovoltaic pv market in china to address the following questions 1 is there evidence of demand induced innovation 2 does the effect of local demand pull policy differ from the effect of non local demand pull policy on demand induced innovation to address these questions we develop and analyze an original database of pv balance of system bos patents in the distributed pv market filed between 2005 and 2014 in china our results support the demand induced innovation hypothesis and suggest that only local demand significantly induces pv bos innovations in the distributed pv market in china the different effects of local demand and non local demand emphasize the importance of local markets and local policies lending some support to bottom up approaches to clean energy governance

social capital and coping with economic shocks an analysis of stunting of south african children abstract south african households live in an environment characterized by risks and many face a significant probability of experiencing economic losses that threaten their daily subsistence using household panel data that include directly solicited information on economic shocks and employing household fixed effects estimation we explore how well households cope with shocks by examining the effects of shocks on child nutritional status unlike in the idealized village community some households appear unable to insure against risk particularly when others in their communities simultaneously suffer large losses households in communities with more social capital however seem better able to weather shocks

an evaluation of the importance of subsistence food production for assessments of poverty and policy targeting evidence from romania a representative survey of romanian households highlights the importance of subsistence food production to consumer welfare estimates of the incidence of poverty are sensitive to the valuation of subsistence production particularly for certain sub groups the characteristics of those engaged in subsistence food production are profiled and sub groups identified using a combination of factor and cluster analysis the factor analysis identifies three dimensions of indicators to characterise households rurality financial resources and time dedicated to main activity based on these factors four clusters of romanian households are identified the two poorest groups are the most rural and dependent on subsistence production and the assessment of the latter s value is most important to these groups in terms the numbers classified as poor poverty alleviation strategies for each sub group are discussed

poverty and household size the widely held view that larger families tend to be poorer in developing countries has influenced research and policy the scope for size economies in consumption cautions against this view we find that the correlation between poverty and size vanishes in pakistan when the size elasticity of the cost of living is about 0 6 this turns out to be the elasticity implied by a modified version of the food share method of setting scales by contrast some measures of child nutritional status indicate an elasticity of unity consideration of the weight attached to child versus adult welfare may help resolve the non robustness of demographic profiles of poverty excerpt

renewable energy and the environment in south africa a way forward the need to mitigate the adverse environmental impacts of fossil fuel usage the volatility of fuel prices and enhancement of national energy security have largely driven a phenomenal growth around the world in renewable energy re generation particularly grid connected over the past two decades the necessity to apply policy support instruments to promote the dissemination of these technologies is now a universally accepted norm different countries and societies depending on the prevailing socio economic environment draft and apply their policy frameworks differently and debates abound as to which mechanisms should have been most suitable under which circumstance most of these debates however assume the existence of an intrinsic political environment in favour of the process in south africa the current political environment is not very conducive to the development of a sustainable re industry this paper explores some of the anomalies and barriers and suggests possible options for a way forward to a viable re industry in the country

agricultural technology risk and gender a cge analysis of mozambique abstract interactions between agricultural technology improvements risk reducing behavior and gender roles in agricultural production in mozambique are examined the analysis employs a computable general equilibrium cge model that explicitly incorporates key features of the economy these include detailed accounting of marketing margins home consumption risk and gender roles in agricultural production our results show that agricultural technology improvements benefit both male and female occupants of rural households due to economic interactions agricultural technology improvements are particularly compelling when combined with marketing system improvements moreover technological change in cassava appears to be a particularly strong lever for increasing female and overall household welfare especially when risk is considered

measuring food insecurity the frequency and severity of coping strategies abstract defining and interpreting food security and measuring it in reliable valid and cost effective ways have proven to be stubborn problems facing researchers and programs intended to monitor food security risks this paper briefly reviews the conceptual and methodological literature on food insecurity measurment describes a particular method for distinguishing and measuring short term food insecurity at the household level and discusses ways of generalizing the method the method developed enumerates the frequency and severity of strategies relied on by urban households when faced with a short term insufficiency of food this method goes beyond more commonly used measures of caloric consumption to incorporate vulnerability elements of food insecurity as well as the deliberate actions of household decision makers when faced with food insufficiency

on the trade off between real time pricing and the social acceptability costs of demand response abstract dynamic tariff policies have become an essential feature of modern electric grid design the successful implementation of such policies usually depends on overcoming the resistance of end users to real time pricing and its political implications in this paper we review the literature on the social acceptability costs of implementing demand response programs and we discuss the key features of implementing a real time price to energy although the literature acknowledges the existence of a social acceptability cost it does not propose an explicit approach to dealing with this issue a model for investigating the implications of the social acceptability cost is thus introduced and through it we discuss thoroughly the joint impact of the elasticity and externality parameters on the tariff design of a demand response program we explore how the increases in elasticity and in externality effects influence price changes in such programs and how the social acceptability cost could be reduced as a function of pricing policies we conclude by discussing the policy design mechanisms in line with demand elasticity and their role in decreasing price variations to cope with the minimum volatility principle in the presence of policies that penalize high prices there is an even further decrease in price variations

international cooperation on climate friendly technologies we examine international cooperation on technological development as an alternative to international cooperation on emission reductions we show that without any r d cooperation r d in each country should be increased beyond the non cooperative level if i the technology level in one country is positively affected by r d in other countries ii the domestic carbon tax is lower than the pigovian level or iii the domestic carbon tax is set directly through an international tax agreement we also show that a second best technology agreement has higher r d higher emissions or both compared with the first best outcome the second best subsidy always exceeds the subsidy under no international r d cooperation further when the price of carbon is the same in the second best technology agreement and in the case without r d cooperation welfare is highest r d is highest and emissions are lowest in the second best r d agreement

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

estimating utility consistent poverty lines with applications to egypt and mozambique abstract a fundamental premise of absolute poverty lines is that they represent the same level of utility through time and space disturbingly a series of recent studies in middle and low income economies show that even carefully derived poverty lines rarely satisfy this premise this article proposes an information theoretic approach to estimating cost of basic needs cbn poverty lines that are utility consistent applications to date illustrate that utility consistent poverty measurements derived from the proposed approach and those derived from current cbn best practices often differ substantially with the current approach tending to systematically overestimate underestimate poverty in urban rural zones

a participatory approach to sustainable energy strategy development in a carbon intensive jurisdiction the case of nova scotia the need for governments to reduce the exposure of energy consumers to future increases in fossil fuel prices places urgent pressure on policy makers to deliver fundamental transformations in energy strategies particularly in jurisdictions with high dependency on fossil fuel sources dorian et al 2006 this transformation is unlikely without a high level of stakeholder engagement in the policy development process this paper describes two policy development processes recently undertaken in nova scotia in which the inclusion of stakeholder views was central to the approach the first delivered a new institutional framework for electricity energy efficiency involving the inception of an independent performance based administrator the second required the delivery of a strategy to significantly increase renewable energy generation in the province it involved recommendations for changes in institutional arrangements financial incentives and technological options this process was followed by new commitments to renewable energy developments new infrastructure for the importation of hydro electricity and the announcement of fits for ocean energy in both cases recommendations were made by an independent academic institution and the government responded directly to a majority of recommendations the paper concludes with a discussion of lessons learned and the implications for future energy policy making in carbon intensive jurisdictions

a review on promoting share of renewable energy by green trading mechanisms in power system abstract in order to promote the development of renewable energy power generation many countries have issued corresponding policies meanwhile some green trading mechanisms have been implemented in power industry and this paper has mainly presented a review on promoting share of renewable energy by green trading mechanisms in power system with a focus on promotion effects of three mechanisms feed in tariff renewable portfolio standard and emission trading scheme apart from a review summaries comparisons and an outlook for future study are also presented our review suggests that feed in tariff and renewable portfolio standard can effectively increase the share of renewable energy power and lead to renewable resource diversity in addition emission trading also provides stimulus for development of renewable energy besides mitigation of carbon emission

wind turbine manufacturing in china a review abstract domestic wind turbine manufacturing sector in china has experienced development stages starting from scratch to mass production during the 11th fyp period 2006 2010 the main goal of wind power policy in china is to promote the commercialization of wind power by large scale deployment of wind farms this goal has been realized to a great extent and now the cost of wind power generation is nearly comparable to coal fired power generation in china the industry policy which devotes to mass production of domestic wind turbines is also largely successful the purpose of the paper is to provide an overview on wind turbine manufacturing sector in china the policy evolution in different stages achievements and challenges pertinent to the sector are addressed in the paper key findings are that the misleading industry policy which provides strong incentive to blind entrance and competition for scale and price and restrains innovation as well is the key obstacle for the sustainable development of the sector deficient technology standard and qualification system and the misplaced franchise bidding system also indulge vicious competition and oversupply creating a level playground for all turbine supplies providing strong incentive to innovative manufacturers establishing thorough and practicable standard and qualification system and fine tuning the directive of the franchise bidding system towards technology and service are the primary policy implications proposed by our study

social acceptance of renewable energy innovation an introduction to the concept this paper introduces the special issue on social acceptance of renewable energy innovation it is a collection of best papers presented at an international research conference held in tramelan switzerland in february 2006 while there are ambitious government targets to increase the share of renewable energy in many countries it is increasingly recognized that social acceptance may be a constraining factor in achieving this target this is particularly apparent in the case of wind energy which has become a subject of contested debates in several countries largely due to its visual impact on landscapes this paper introduces three dimensions of social acceptance namely socio political community and market acceptance factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects the third dimension market acceptance has received less attention so far and provides opportunities for further research particularly from management scholars

joint r d in low carbon technology development in china a case study of the wind turbine manufacturing industry abstract china faces the dual challenges of climate change and increased energy demand these challenges in turn increase the demand for wind energy development along with rapid growth in manufacturing capacity chinese companies have aspired to increase their innovation capacity in order to enhance their competitiveness in the market joint research and development r d is an attractive path for chinese companies striving to advance their r d capacity this paper examines joint r d between chinese wind turbine manufacturing companies and foreign design firms assessing the performance of joint r d activities in china using the structure conduct performance scp framework the study found that joint r d has improved chinese companies technical capacity human resources and financial growth however the effect on chinese companies innovation capacity is still limited because of unequal technical capacities of the two sides in collaboration as well as their preference for augmenting profits rather than technical capacity current joint r d mode is only the extension of licensing mode in wind turbine manufacturing industry

policies to accelerate the growth of offshore wind energy sector in india abstract india s power generation capacity needs to be augmented to support the growing demands for electricity india which has predominantly used fossil fuels to power its generators need to make a switch to clean energy fuels but renewable sources form a miniscule portion 26 gw 12 of india s overall installed power capacity 210 gw there is no contribution from offshore wind farms to the energy basket for india as there is no policy framework to encourage the development of offshore wind farms several european countries have tapped the offshore wind energy potential to reduce their dependence on adopted by these countries to identify the core components 21 of them of robust policy intervention a detailed questionnaire was administered to 181 stakeholders of wind energy in india to seek their feedback on these building blocks these core components variables in research parlance are then subjected to factor analysis to understand the underlying structure of the variables the factor analysis logically reduces these 21 variables into five factors government support fiscal and quota based incentives availability of local expertise capital for investments and building an enabling r d ecosystem which are then fed into a logistic regression model as independent variables to predict the probability of growth of offshore wind energy dependent variable in the country the logistic regression model gives the weight the impact of these independent variables in influencing the growth of offshore wind energy in india it emerges that government support fiscal and quota based incentives and building an enabling r d ecosystem have a much higher impact on the growth of offshore wind energy for india this paper fills the gap of absence of an empirically tested framework on offshore wind energy policy for india

brother can you spare a dime peer pressure in charitable solicitation abstract while the effects of peer pressure in charitable giving have been of considerable interest to social scientists there is little empirical evidence on the magnitude of these effects a correlation between giving or volunteering by one s peers and one s own giving can be driven by self selection into groups common shocks that inspire both the solicitor to ask and the individual to give or social influence using data from a university this paper analyzes whether alumni are more likely to give and give larger amounts when they are solicited by someone with whom they have social ties freshman year roommate assignments and the structure of the university s giving campaigns are used to overcome problems of selection and common shocks social ties play a strong causal role in the decision to donate and the average gift size additionally a solicitor s request is much more effective if he or she shares characteristics such as race with the alumnus being solicited

consistent poverty comparisons and inference building upon the cost of basic needs cbn approach an integrated approach to making consumption based poverty comparisons is presented this approach contains two principal modifications to the standard cbn approach the first permits the development of multiple poverty bundles that are utility consistent the second recognizes that the poverty line itself is a random variable whose variation influences the degree of confidence in poverty measures we illustrate the empirical importance of these two methodological changes for the case of mozambique with utility consistency imposed estimated poverty rates tend to be systematically higher in rural areas and lower in urban areas we also find that the true confidence intervals on the poverty estimates those incorporating poverty line variance tend to be considerably larger than those that ignore poverty line variance finally we show that these two methodological changes interact specifically we find that imposing utility consistency on poverty bundles tends to tighten confidence intervals sometimes dramatically on provincial poverty estimates we conclude that this revised approach represents an important advance in poverty analysis the revised approach is straightforward and directly applicable in empirical work

design of an economically efficient feed in tariff structure for renewable energy development abstract evidence suggests albeit tentatively that feed in tariffs fits are more effective than alternative support schemes in promoting renewable energy technologies rets fits provide long term financial stability for investors in rets which at the prevailing market price of electricity are not currently cost efficient enough to compete with traditional fossil fuel technologies on the other hand if not properly designed fits can be economically inefficient as is widely regarded to have been the case under the public utility regulatory policies act of 1978 purpa under purpa too high a guaranteed price led to the creation of so called purpa machines poorly performing generating units that could survive financially only because of heavy subsidies that came at the expense of retail customers similarly because of their adverse impacts on retail electricity rates german fits have been subject to increasing political pressure from utilities and customers in this paper we propose an innovative two part fit consisting of both a capacity payment and a market based energy payment which can be used to meet the renewables policy goals of regulators our two part tariff design draws on the strengths of traditional fits relies on market mechanisms is easy to implement and avoids the problems caused by distorting wholesale energy markets through above market energy payments the approach is modeled on forward capacity market designs that have been recently implemented by several regional transmission organizations in the usa to address needs for new generating capacity to ensure system reliability

energy security in china a quantitative analysis and policy implications abstract this study aims to examine how china s energy security has changed over 30 years of reform and the opening period it constructs a 4 as quantitative evaluation framework the availability of energy resources the applicability of technology the acceptability by society and the affordability of energy resources the quantitative results show that china s energy security was at its best during the sixth fyp period 1981 1985 but then deteriorated until it hit higher levels between 1995 and 2005 however it was still lower than the level reached during the sixth fyp period during the eleventh fyp period 2006 2010 the energy security situation deteriorated again differences in policy priority over the study period appear to affect the country s energy security status this study suggests that china needs to develop renewable energy resources on a large scale and pay more attention to emissions control to reverse the downward trend in energy security

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

between fragmented authoritarianism and policy coordination creating a chinese market for wind energy abstract the chinese grid connected wind energy sector has undergone a number of fundamental changes during its 20 years of existence the scope of this article is to track the reforms of the energy bureaucracy and its policy approach on the one hand and changes in wind energy installations on the other by comparing three historically distinct phases of wind energy in china it is shown how policy reforms have changed largely from a state of fragmented authoritarianism towards policy coordination in the initial phase 1986 1993 wind energy was expanding very slowly with disjointed policy making and in the incremental phase 1994 1999 the energy authorities were in dispute over the strategy and launched conflicting policy initiatives with poor results in wind energy output the latest coordinated phase 2000 2006 however developed a coherent renewable energy agenda and policy regime for the wind power sector it is found that this phase with coordinated market regulations and incentives has helped give birth to a take off in chinese wind energy installations and substantial cost reductions although the latter is threatening the profitability of wind farms the article contributes to the academic debate over the role of policy making in renewable energy development and argues that china should continue and improve the coordination of regulations and incentives

an overview of incentive policies for the expansion of renewable energy generation in electricity power systems and the brazilian experience abstract energy production from renewable sources is already a reality in many countries and with that different strategies for incentivizing investments in renewable energy generation have been proposed and used over the years in this study long term policies that have been applied in several countries such as feed in tariffs shares with commercialization of certificates auctions and net metering are overviewed and discussed the main advantages and disadvantages of these incentive strategies are emphasized focusing on applications some of these strategies that have already been applied in brazil are analyzed in greater depth emphasizing the potentialities and fragilities of these mechanisms observed within the country even though it is a country that stands out in relation to other latin american countries regarding electricity generation from non hydro renewable sources brazil still faces barriers that prevent a utilization compatible with its potential moreover the trend for renewable sources such as wind and solar power is to represent an energy capacity reserve to cover hydrological risks and also to contribute to a distributed generation spread through electricity distribution networks

wind farm investment risks under uncertain cdm benefit in china abstract china has set an ambitious target to increase its wind power capacity by 35 gw from 2007 to 2020 the country s hunger for clean power provides great opportunities for wind energy investors however risks from china s uncertain electricity market regulation and an uncertain energy policy framework mainly due to uncertain clean development mechanism cdm benefits prevent foreign investors from investing in china s wind energy the objectives of this paper are to 1 quantify wind energy investment risk premiums in an uncertain international energy policy context and 2 evaluate the impact of uncertain cdm benefits on the net present values of wind power projects with four scenarios this study simulates possible prices of certified emissions reductions cers from wind power projects project net present values npvs have been calculated the project risk premiums are drawn from different and uncertain cer prices our key findings show that uncertain cdm benefits will significantly affect the project npvs this paper concludes that the chinese government needs revising its tariff incentives most likely by introducing fixed feed in tariffs fits and re examining its cdm granting policy and its wind project tax rates to facilitate wind power development and enable china to achieve its wind energy target

renewable energy gathers steam in south africa abstract south africa s renewable energy independent power producers procurement programme the rei4p is an extensive initiative to install 17 8 gw of electricity generation capacity from renewables wind solar biomass biogas and hydropower over the period 2012 2030 although at the outset the rei4p seemed an expensive option designed only to deflect criticism of south africa s high carbon footprint and excessive dependence on coal based electricity generation the escalating costs of the latter the rapidly falling costs of photovoltaic and wind power and the increasingly competitive bidding process of the rei4p have changed this prospect at the conclusion of round three the weighted cost of energy has reached a 23 discount to the cost of new coal based generation and a 28 discount to global renewable energy prices the bidders commitments to local employment creation have similarly increased from 11 to 18 jobs mw the programme is now well placed to deliver on a broad range of objectives including regional development and black economic empowerment however maximum benefit from the rei4p will not be secured without some revision to aspects of the bidding and procurement process more specifically the local content provisions need to be tightened to drive higher levels of local manufacturing

food poverty profile applied to kenyan smallholders that can be used to test conflicting hypotheses this paper analyzes data from the first kenyan integrated rural survey irs i household expenditure data collected by the central bureau of statistics to estimate the magnitude distribution of and factors associated with food poverty among kenyan small farmers the analysis uses a new methodology with three improvements over previous empirical studies 1 food poverty is estimated using an additively decomposable measure that allows poverty to be distributed among population subgroups 2 the food poverty line is based on observed dietary preferences in response to regional food prices and 3 the food poverty measure is adjusted to use regional food poverty lines without sacrificing its theoretical properties or decomposability this paper consists of two main parts section ii reviews the methodology underlying the setting of the regional food poverty line on the basis of a detailed integrated rural survey of kenyan smallholders the cost of food consumption corresponding to the recommended dietary allowance rda of calories is computed since this food poverty line was calculated on the basis of the observed diet consumed it presumably reflects the prevailing regional food preferences and prices faced by households consuming around the calorie rda level the next part of section ii presents a food poverty measure that in addition to satisfying the major fundamental properties of such measuresis decomposable and allows regional food poverty deprivation to be estimated

policies and market factors driving wind power development in the united states abstract in the united states there has been substantial recent growth in wind energy generating capacity with growth averaging 24 percent annually during the past five years about 1700 mw of wind energy capacity was installed in 2001 while another 410 mw became operational in 2002 during 2003 development activity has remained strong with an estimated 1600 mw of capacity installed with this growth an increasing number of states are experiencing investment in wind energy projects currently about half of all states host at least one wind power project this paper explores the key factors at play in the 12 states in which a substantial amount of wind energy capacity has been developed or planned some of the factors that are examined include policy drivers such as renewable portfolio standards rps federal and state financial incentives as well as market drivers such as consumer demand for green power natural gas price volatility and wholesale market rules

charity donations in the uk new evidence based on panel data abstract this paper presents a set of panel data estimates for 159 of the most prominent uk charities for the period 1983 1990 in evaluating alternative specifications we settle on a fixed effects estimation social welfare charities are shown to fund raise short of the point at which net revenues are maximized whereas health and overseas charities are found to net revenue maximize religious charities maximize total revenues estimates of price and fund raising elasticities are presented for charities overall and for four cohorts for alternative income sources no evidence of crowding out is found

has regulation of charitable foundations thrown the baby out with the bath water abstract regulations to curb tax avoidance and evasion through charitable foundations have been in place since the tax reform act of 1969 newly compiled longitudinal data makes it possible to estimate the effects of these regulations by comparing affected and unaffected foundations before and after the reform donations and entry dropped precipitously proxy variables suggest significant deterrence of abuses but half of the decline in donations can be explained by the increased cost of running a foundation the results highlight the potential for large reductions in the benefits of regulation when the cost of compliance affects externality producing actions such as charitable giving

dynamic income progressive taxes and the timing of charitable contributions using an econometric model of charitable giving and a 10 year panel of tax return data i find that previous studies have underestimated the effects of permanent income and overestimated the effects of permanent changes in tax prices the significant statutory tax changes that occurred during the 1980s especially in 1986 serve to identify the key model parameters my results imply that people smooth their giving when transitory income changes but also time their giving to exploit transitory changes in tax prices the results also raise questions about how effectively the tax incentives permanently influence the level rather than just the timing of charitable giving by individuals

how robust is a poverty profile comparison of poverty such as when poverty is greatest typically matter far more for policy choices than do aggregate measures of poverty such as how many people are deemed poor the authors examine alternative methods for constructing poverty profiles focusing on their internal consistency and appropriateness for guiding policy none is perfect but some methods appear to be preferable to others when the aim is to inform policies for fighting absolute consumption poverty a case study on indonesia reveals that the country s regional and sectoral poverty profile is highly sensitive to some aspects of measurement but quite robust to others

optimal tax treatment of private contributions for public goods with and without warm glow preferences abstract tax favored contributions for financing some public goods may be a useful part of optimal nonlinear income tax and expenditure policy there are two sides to the potential gain from subsidized donations first for a given level of public good provision higher private donations from high earners than low earners eases the incentive compatibility constraint for donors and so can raise social welfare this follows since considering a lower paid job includes a perception of a drop in public good provision second private donation reduces consumption easing the resource constraint this paper explores optimal policy using first a model with standard preferences and then a model with a warm glow of giving in addition to showing the conditions for the level of public goods the paper considers the pattern of optimal subsidization across earnings levels analysis of optimal taxation with warm glow preferences is sensitive to the choice of preferences that are relevant for a social welfare evaluation after considering optimal rules with formulations of social welfare which do and do not include warm glow utility the paper considers the choice of normative criterion like the earlier literature this paper assumes that organizing private donations is costless while tax collection has a deadweight burden since private charitable fundraising is very far from costless the paper is an exploration of economic mechanisms not a direct guide to policy

the robustness of poverty profiles reconsidered poverty measures and profiles are used increasingly to guide antipoverty policies in low income countries an essential element in these analyses is the specification of a poverty line however there are many different methods for setting poverty lines and different methods can yield strikingly different results with correspondingly different policy implications using recent household survey data from mozambique this paper explores the differences that occur using the most common poverty line methodologies the food energy intake fei and the cost of basic needs cbn methods over different levels of geographic specificity we find that regional and provincial rankings of foster greer and thorbecke poverty indices are not robust to the method of poverty line determination but that the characteristics of the poor are reasonably similar under all methods the fei poverty lines often yield counterintuitive results whereas the family of cbn poverty lines was more robust food consumption patterns of the poor show a high degree of substitution among basic staples from one region to another which is consistent with observed differences in relative food prices indicating that cbn poverty lines that allow for regional variation in the food consumption bundle may be most appropriate in these settings

alternatives to coal and candles wind power in china china is in a unique position to be able to exploit her vast wind resources to satisfy both the rapidly growing energy demand which fuels her economy as well as needs of approximately 72 million people who live in rural areas and have no access to conventional electricity services china mainly through the e orts of the inner mongolia autonomous region has already successfully disseminated over 150 000 small scale wind electric generators which power households in rural areas through a well coordinated combination of local research and development technology transfer industry support end user incentives and an infrastructure for information dissemination and technical training in this paper we review china s utilization of wind energy and discuss how it can be increased for both rural electri cation and the rapidly growing power sector we nd that novel approaches in technical implementation of wind power use may help to better meet china s needs use of hybrid systems may help to provide higher quality more reliable power for rural households and villages than is currently provided through wind only systems grid connected wind power which currently is more costly and less reliable than coal power can become cost competitive and more reliable through local mass production of wind turbines combined with storage systems we examine governmental support through policy infrastructure development and nancial incentives that have fostered the successes of dissemination of small scale wind turbines and also the support or lack thereof that has hindered commercial development of large scale wind power we nd that a better policy and regulatory framework is the most important measure that china can take to increase the use of this indigenous clean resource 2000 elsevier science ltd all rights reserved

is there an intrahousehold flypaper effect evidence from a school feeding programme are public transfers targeted toward children neutralised by the household as the theory of altruism implies or is there an intrahousehold flypaper effect whereby such transfers stick to the child this paper studies the impact of a school feeding programme on child caloric intake in the philippines using a quasi experimental methodology the empirical results confirm an intrahousehold flypaper effect indeed they indicate virtually no intrahousehold reallocation of calories in response to the feeding programme in poorer households however children s gains from the programme appear to be taxed more heavily

a two part feed in tariff for intermittent electricity generation abstract as electricity generation from intermittent energy sources wind sun tides is gaining momentum it becomes increasingly important to price these electricity sources efficiently conventional flat feed in tariffs ignore the heterogeneity of these sources taking into account the degree of substitutability or complementarity of these sources with respect to each other and with respect to stochastic demand variations this paper derives optimal pricing instruments composed of a feed in tariff fit and a capacity augmentation tariff cat an empirical analysis looks at wind and solar farms operating in ontario in order to determine the optimal use of fit cat pricing the magnitude of optimal price differentiation turns out to be economically significant furthermore the emergence of grid scale electricity storage underscores the need to price energy and capacity separately

explaining the evolution of poverty the case of mozambique we provide a comprehensive approach for analyzing the evolution of poverty using mozambique as a case study bringing together data from disparate sources we develop a novel back casting framework that links a dynamic computable general equilibrium model to a micro simulation poverty module this framework provides a new approach to explaining and decomposing the evolution of poverty as well as to examining rigorously the coherence between poverty economic growth and inequality outcomes finally various simple but useful and rarely applied approaches to considering regional changes in poverty rates are presented copyright 2012 oxford university press

the large scale solar feed in tariff reverse auction in the australian capital territory australia abstract feed in tariffs fits offer renewable energy developers significant investor certainty but sometimes at the cost of being misaligned with generation costs reverse fit auctions where the fit rights for a predetermined capacity are auctioned can overcome this problem but can be plagued by non delivery risks particularly of competitively priced proposals in 2012 and 2013 the australian capital territory act government in australia conducted a fit reverse auction for 40 mw of large scale solar generating capacity the first such auction undertaken in the country the auction was highly competitive in relation to price and demonstrating low delivery risks proposal capital costs particularly engineering procurement and construction costs as well as internal rates of return were lower than expected the auction process revealed limited land availability for large scale solar developments in the act as well as a significant perceived sovereign risk issue the auction process was designed to mitigate non delivery risk by requiring proposals to be pre qualified on the basis of delivery risk before considering fit pricing the scheme is likely to be used by the act government to support further large scale renewable energy development as part of its greenhouse gas reduction strategy which is underpinned by a 90 per cent by 2020 renewable energy target

review of china s wind power firms internationalization status quo determinants prospects and policy implications abstract in recent years an increasing number of chinese wind power firms have been going international in search of global market for development channels by employing qualitative research and case study methods this paper examines the export scale and markets of china s wind turbines the market entry modes and location choices of china s outward foreign direct investment fdi in the wind power sector identifies the determinants and prospects of chinese wind firms internationalization as well as provides policy implications it is found that chinese wind power firms has chosen to internationalize very differently from the uppsala model in that the exports and fdi of chinese wind power firms both took place around 2008 and the exports and fdi of chinese wind power firms are closely linked the determinants of chinese wind firms internationalization are the competitive advantages of leading chinese wind firms and the intensified domestic market competition followed by chinese government support for internationalization and the attractive overseas market the prospects of chinese wind firms internationalization are bright but challenging drawn on this analysis conclusions and three policy implications are provided at the end of the paper this paper contributes to the study of china s wind power sector from a new perspective

an affinity to commons model of public support for environmental energy policy abstract as atmospheric co 2 continues to rise above 450 ppm policymakers struggle with uncertainty concerning predictors of citizen support for environmental energy policies eeps and preferences for their design topics which have received limited attention in empirical literature we present an original model of policy support based on citizens affinity to commons pathways by which individuals enjoy natural public goods that in turn shape preferences between alternative policy mechanisms we evaluate this model using a survey of southern california electricity customers with results indicating the model s utility in predicting public support of eep stronger community ties are associated with preferences for pull type subsidies whereas stronger connections to natural commons are linked to support for both pull and push type sanctions findings have implications for coalition building as advocates may engender support for green energy policy by framing sanctions as protecting natural commons and framing subsidies either in this same way and or as producing benefits for communities

are experience and schooling complementary evidence from migrants assimilation in the bangkok labor market abstract this paper models the assimilation process of migrants and shows evidence of the complementarity between their destination experience and upon arrival human capital bayesian learning is assessed using panel data of wages from bangkok thailand it is found that i schooling returns are lower for migrants than for natives ii the accumulation of destination experience raises wages for migrants iii the experience effect is greater for more educated agents and iv the complementarity increases as destination experience accumulates the results imply that more educated migrants have higher learning efficiency and can perform tasks of greater complexity ultimately yielding higher wage growth in the destination market

long term effects of feed in tariffs and carbon taxes on distribution systems in deregulated electricity sector climates such as in ontario the production of clean or renewable energy by small power producers through distributed generation dg is encouraged this paper examines the policies that can be used to encourage dg investment and incorporates them into a mathematical model this model is then used to create scenarios for examining the economic and environmental supply side effects of policies to a distribution system over a ten year period the policies analyzed include a combination of feed in tariffs co2 tax and cap and trade schemes the results are discussed in the context of the ontario market and its standard offer program implemented on a 32 bus radial distribution system

trust membership in groups and household welfare evidence from kwazulu natal south africa unfortunately these two literatures have remained largely unconnected the group and network literature concludes that participation has important economic benefits even when the stated function of the group is noneconomic in most cases however the mechanisms by which groups and networks achieve this are unclear the determinants of trust and participation in groups literature highlights the importance of income and social homogeneity what remains less understood is whether and how trust can be generated for example via participation in groups this article links the empirical literatures referenced above by exploring the relationship between membership in groups and trust specifically using longitudinal data from kwazulu natal province south africa we examine 1 the importance of trust in the decision to join groups 2 the subsequent ability of groups to generate trust and 3 the effect of group membership and trust on a measure of well being per capita household income in addition we disaggregate groups into financial and nonfinancial and we categorize trust in people by agent or actor therefore we can explore whether trust in different kinds of actors is important for participation in different kinds of groups and whether participation in different kinds of groups is important for generating trust in different kinds of actors excerpt

poverty in egypt modeling and policy simulations abstract poverty profiles are a useful way of summarizing information on the levels of poverty and the characteristics of the poor in a society but they are limited by the bivariate nature of their informational content using the 1997 egypt integrated household survey eihs this article estimates models of household consumption in the first stage and then predicts poverty rates corresponding to changes in potential policy variables the key results of the study point to the important instrumental role of education parental background land redistribution and access to health facilities in alleviating poverty in egypt

a tale of two market failures technology and environmental policy abstract market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies these combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives and can be cost effectively harnessed through the use of economic incentive based policy in the presence of weak or nonexistent environmental policies investments in the development and diffusion of new environmentally beneficial technologies are very likely to be less than would be socially desirable positive knowledge and adoption spillovers and information problems can further weaken innovation incentives while environmental technology policy is fraught with difficulties a long term view suggests a strategy of experimenting with policy approaches and systematically evaluating their success

fostering a renewable energy technology industry an international comparison of wind industry policy support mechanisms this article examines the importance of national and sub national policies in supporting the development of successful global wind turbine manufacturing companies we explore the motivations behind establishing a local wind power industry and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders this is done through a cross country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries we find that in many instances there is a clear relationship between a manufacturer s success in its home country market and its eventual success in the global wind power market whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market which in turn will be influenced by the annual size and stability of that market consequently policies that support a sizable stable market for wind power in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally are most likely to result in the establishment of an internationally competitive wind industry

energy policymaking in denmark implications for global energy security and sustainability denmark is arguably the most energy secure and sustainable country in the organization of economic cooperation and development oecd the country has reduced its dependence on foreign sources of energy to zero and become self sufficient in its own energy production and use offering important lessons for other nations around the world this study explores the core of denmark s successful approach a commitment to energy efficiency prolonged taxes on energy fuels electricity and carbon dioxide and incentives for combined heat and power chp and wind turbines through these commitments the study shows how denmark transitioned from being almost 100 percent dependent on imported fuels such as oil and coal for their power plants in 1970 to becoming a net exporter of fuels and electricity today the country leads the world in terms of exportation of wind energy technology with a hold on roughly one third of the world market for wind turbines it was able to phase out the use of virtually all oil fired power plants in less than five years and implemented a progressive moratorium on future coal fired power plants in the 1990s their most recent strategy seeks to achieve 30 percent of total energy supply from renewable energy by 2025

international technology oriented agreements to address climate change much discussion has surrounded possible alternatives for international agreements on climate change particularly post 2012 among these alternatives technology oriented agreements toas are perhaps the least well defined we explore what toas may consist of why they might be sensible which toas already exist in international energy and environmental governance and whether they could make a valuable contribution to addressing climate change we find that toas aimed at knowledge sharing and coordination research development or demonstration could increase the overall efficiency and effectiveness of international climate cooperation but are likely to have limited environmental effectiveness on their own technology transfer agreements are likely to have similar properties unless the level of resources expended is large in which case they could be environmentally significant technology specific mandates or incentives could be environmentally effective within the applicable sector but are more likely to make a cost effective contribution when viewed as a complement to rather than a substitute for flexible emissions based policies these results indicate that toas could potentially provide a valuable contribution to the global response to climate change the success of specific toas will depend on their design implementation and the role they are expected to play relative to other components of the policy portfolio

the politics of renewable energy policies the case of feed in tariffs in ontario canada designing and implementing a renewable energy policy involves political decisions and actors yet most research on renewable energy policies comparatively evaluates instruments from an economic or technical perspective this paper presents a case study of ontario s feed in tariff policies between 1997 and 2012 to analyze how the political process affects renewable energy policy design and implementation ontario s policy although initially successful has met with increasing resistance over time the case reveals key political tensions that arise during implementation first high level support for a policy does not necessarily translate into widespread public support particularly for local deployment second the government often struggles under asymmetric information during price setting which may weaken the policy s legitimacy with the public due to higher costs third there is an unacknowledged tension that governments must navigate between policy stability to spur investment and adaptive policymaking to improve policy design fourth when multiple jurisdictions pursue the same policies simultaneously international political conflict over jobs and innovation may occur these implementation tensions result from political choices during policy design and present underappreciated challenges to transforming the electricity system governments need to critically recognize the political dimension of renewable energy policies to secure sustained political support

dynamics of energy technologies and global change technological choices largely determine the long term characteristics of industrial society including impacts on the natural environment however the treatment of technology in existing models that are used to project economic and environmental futures remains highly stylized based on work over two decades at iiasa we present a useful typology for technology analysis and discuss methods that can be used to analyze the impact of technological changes on the global environment especially global warming our focus is energy technologies the main source of many atmospheric environmental problems we show that much improved treatment of technology is possible with a combination of historical analysis and new modeling techniques in the historical record we identify characteristic l such network e ects yield high barriers to entry even for superior competitors these simple observations allow three improvements to modeling of technological change and its consequences for global environmental change one is that the replacement of long lived infrastructures over time has also replaced the fuels that power the economy to yield progressively more energy per unit of carbon pollution from coal to oil to gas such replacement has d they also include endogenous generation of s we show that doing so can yield projections with lessened environmental impacts without necessarily incurring negative e ect on the economy arriving on that path by the year 2100 depends on intervening actions such as incentives to promote greater diversity in technology and lower barriers to entry for new infrastructures that could accelerate historical trends of decarbonization 1999 elsevier science ltd all rights reserved
