learning wage dynamics and firm specific human capital we introduce a dynamic and fully strategic model of wage determination in the presence of firm specific human capital in this model human capital is interpreted as information we show that equilibrium exists and is efficient and that it gives rise to a unique distribution of the social surplus we show further that the equilibrium wage is determined by three factors consideration of these factors allows us to determine when and how the market mechanism enables the worker to capture some of the returns to firm specific human capital we relate our findings to the ongoing empirical debate concerning the return to tenure

does financial education impact financial literacy and financial behavior and if so when in a meta analysis of 126 impact evaluation studies we find that financial education significantly impacts financial behavior and to an even larger extent financial literacy these results also hold for the subsample of randomized experiments rcts however intervention impacts are highly heterogeneous financial education is less effective for low income clients as well as in low and lower middle income economies specific behaviors such as the handling of debt are more difficult to influence and mandatory financial education tentatively appears to be less effective thus intervention success depends crucially on increasing education intensity and offering financial education at a teachable moment

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

liquid biofuels in china current status government policies and future opportunities and challenges abstract china like many other countries is promoting the development of liquid biofuel including bioethanol and biodiesel the chinese government has set biofuel development targets for the coming decade and sanctioned a series of supportive policies this paper provides a comprehensive overview of current liquid biofuel development in china related government policies and the potential opportunities and challenges for its future expansion our assessment is based on two rounds of in depth fieldwork and a thorough literature review the assessment shows that the prevailing concern on food security has pushed china to move from cereal based to non cereal based biofuel production emphasis has also been put on utilizing new marginal land for feedstock production our assessment indicates that the targets of china s biofuel development are cautious and feasible but on the other hand there are still severe challenges for the sustainability of such development a better understanding of china s experience in striking a balance between energy security food security and environmental protection would inform the debates across country boundaries and contribute to the efforts for global sustainability

changing energy intensity of economies in the world and its decomposition abstract this paper decomposes energy intensity change across countries into five components attributable to technological catch up technological progress and changes in capital energy ratio labor energy ratio and output structure it is found that 1 technological progress capital accumulation and output structure change contributed to the decline of energy intensity from 1980 to 2010 2 changes in labor energy ratio drove up energy intensity and 3 spatial and temporal heterogeneity existed regarding relative importance of the five components

economic assessment of eucalyptus spp for biomass production as alternative crop in southern italy the increase in energy prices and the stagnation of sales prices of the main agricultural commodities required a rethinking of farm production strategies since during the last years thanks to a series of policies aimed at promoting renewable sources it has been a rapid diffusion of lignocellulosic biomass species this paper aimed at evaluating the economic feasibility of the introduction of eucalyptus eucalyptus spp as energy crop for farmers of southern italy by comparing it with traditional crop rotations in particular economic analysis has been carried out in a representative case study located in the sicilian hilly hinterland where in 2013 it has been built a biomass plant for energy production however results showed that introduction of eucalyptus for biomass production is less profitable for farmers than traditional crops considering the incompressibility of production costs and the actual market price of woodchips

women s schooling home teaching and economic growth the hypothesis that increases in the schooling of women enhance the human capital of the next generation and thus make a unique contribution to economic growth is assessed on the basis of data describing green revolution india estimates are obtained that indicate that a component of the significant and positive relationship between maternal literacy and child schooling in the indian setting reflects the productivity effect of home teaching and that the existence of this effect combined with the increase in returns to schooling for men importantly underlies the expansion of female literary following the onset of the green revolution

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

intergenerational transmission of abilities and self selection of mexican immigrants building on borjas 1993 i develop an intergenerational model of self selection of migration and education that allows for a complex selection mechanism in particular it allows for the possibility that agents are selected differently depending on the schooling level they choose as in mayer 2005 i assume that agents are endowed with two abilities manual and intellectual and use the intergenerational structure of the model to infer potential earnings of a person for different levels of education and in different countries this makes it possible to quantify the self selection bias of estimates of the return to education and migration the model is estimated using data on mexicans in the us from the cps and on mexicans residents in mexico from the mexican census the findings are that there is a significant loss of human capital faced by immigrants that is not transmitted to their children while immigrants are observed to earn less because they find it difficult to adapt their skills to the host country their children earn more because they can inherit all the abilities of their parents including that part that could not be used for producing earnings moreover in the case of immigrants parents with larger amounts of intellectual ability migrate more and tend to choose to remain high school educated however they migrate with the expectation of their children becoming college educated therefore measures that rely on the earnings performance and educational attainment of immigrants underestimate the amount of human capital they bring into the host country

agro energy districts contributing to environmental and social sustainability in rural areas evaluation of a local public private partnership scheme in greece abstract the current economic downturn has put public budgets under pressure reducing investments and revenues for local stakeholders to cope among other things with contemporary demands of environmental protection local based partnerships may provide an efficient tool by adopting integrating and implementing actions based on awareness and participation of a set of different players this need is even more evident in rural areas in which a proposed decentralized bio energy production model established in agro energy districtscan provide incentive and create a comfortable ground for the development of an energy production plant based on a mixed public private partnership drawing on the implementation of a european co funded research project the paper presents the efforts being made to build a partnership at a local level in order to cover the lack of an institutional plan and public investment for handling biomass production our aim is not primarily to present the best technical solution to bio energy production but rather to illustrate the networking between different players the public consultation and the agreements being made under the form of public private partnerships as well as the levels of commitment and the risks taken the gist of this study is that despite the civic engagements the inconsistent administrative environment the dominance of the public sector and the state intervention through legislation and different political decisions makes it still difficult for local partnerships to exercise their power and turn from government to governance in order to cope with the environmental challenges and tackle inequalities faced in rural areas

economics of pooling small local electricity prosumers lcoe self consumption abstract the arrival of small scale decentralized energy installations coincides with the emergence of so called prosumers entities households that are producer and consumer of energy in one this research focuses on an electricity prosumer model in the context of the uk market levelized cost of electricity lcoe for photovoltaic pv and wind energy will be modeled for six uk sites additionally self consumption levels for two different load profiles and technologies will be estimated per site the simulations are modeled with homer software and multiple inputs will be varied including natural resource equipment cost maintenance cost equipment life expectancy cost of capital project life and load profiles the modeled self consumption levels show significant differences and varied between 31 and 72 depending on load profile itself and re technologies mixes modeled the pooling of prosumers implied by lower load profile volatility proved to be beneficial to self consumption levels in the modeled scenarios up to 17 6 lcoe showed significant ranges depending on the input parameters and their combination 10 55 p kw h for pv and 2 19 p kw h for wind the combination of these factors is decisive for the final lcoe and the negative effects of less benign factors can be compensated by other parameters when compared to current electricity retail prices of around 15 p kw h around 97 of wind sites and around 4 of pv scenarios implied lcoe reached grid parity the self consumption levels and lcoe analysis indicate the viability of electricity prosumer models

a design of experiments response surface methodology approach to study the economic sustainability of a 1 mwe photovoltaic plant abstract to obtain a rigorous investment analysis for photovoltaic power generation plants a dynamic business plan has been studied it allows us to determine in real time the investment parameters net present value internal rate of return return on investment etc starting from the technical economical financial and positional data the business plan provides as output the exact values of the parameters dependent variables or objective functions basing on the exact values of the input variables independent variables by suitably varying the independent variables it is possible to obtain a sensitivity analysis on the dependent variables due to which different evaluations about the investment in multiple pre set scenarios can be obtained on the other hand by using the business plan as data creator and then applying the response surface methodology techniques it has been possible to obtain mathematical functions regression meta models which are able to explain the link among dependent and independent variables in the definition range this approach allows to generate a sort of k dimensional state equation of order n for the different investigated economic parameters these equations provide in the chosen dimensional space two or three dimensional a view of the dependent variable behaviour e g net present value internal rate of return while changing one or two independent variables e g government incentives discount rate the descriptive ability of this approach has a higher level in terms of quality and reliability than a traditional sensitivity analysis in this paper a case study about a 1 mwe photovoltaic plant located in liguria north italy and a comparison with a similar plant located in sicily south italy are also presented

birth order schooling and earnings birth order effects are posited by many to affect earnings and schooling we show how such effects can be interpreted to shift either the earnings possibility frontier for siblings or parental preferences we find empirical evidence for birth order effects on age adjusted schooling and on earnings for young u s adults though the latter is not robust for all specifications the examination of intrahousehold allocations suggests that these birth order differences occur despite parental preferences or prices by birth order favoring later borns apparently because of stronger endowment effects that favor firstborns

profitability of wind energy investments in china using a monte carlo approach for the treatment of uncertainties abstract china is the global leader in terms of installed wind capacity further wind energy development is expected for the next years and decades to meet the continuously increasing electricity demand and the need of using clean domestic energy since 2009 china is divided into four geographical regions each assigned with a different benchmark on grid tariff moreover the existing infrastructures are not equally developed throughout the country making investment decisions more complicated and risky the scope of this paper is to apply an innovative methodology and evaluate the attractiveness of each region for wind energy development by taking into consideration all relevant investment risks such as wind potential wind curtailment access to the grid and macroeconomic parameters to this purpose a monte carlo simulation approach integrated into a typical financial model is implemented in each of the four regions performing many hundreds of iterations each characterized by a randomly selected set of the examined uncertain parameters this approach intends to provide information to private investors doing a first exploratory research in the huge country s area in order to decide whether and where to invest as well as to policy makers to help them assess critical policy parameters and investigate different scenarios of wind energy development the evaluation of the current framework for wind energy development in china verifies that the existing system of feed in tariffs in china is very effective for the balanced deployment of wind energy in the whole country however it is shown that the risk of curtailment and grid accessibility may significantly reduce the potential profitability of wind energy investments in all four regions priority for development of infrastructures should be given in isolated northern windy areas with high accumulation of wind farms

how financial literacy affects household wealth accumulation this study isolates the causal effects of financial literacy and schooling on wealth accumulation using a new household dataset and an instrumental variables iv approach financial literacy and schooling attainment are both strongly positively associated with wealth outcomes in linear regression models whereas the iv estimates reveal even more potent effects of financial literacy they also indicate that the schooling effect only becomes positive when interacted with financial literacy estimated impacts are substantial enough to imply that investments in financial literacy could have large wealth payoffs

cognitive constraints on valuing annuities this paper documents consumers difficulty valuing life annuities using a purpose built experiment in the american life panel we show that the prices at which people are willing to buy annuities are substantially below the prices at which they are willing to sell them we also find that buy values are negatively correlated with sell values and that the sell buy valuation spread is negatively correlated with cognition this spread is larger for those with less education weaker numerical abilities and lower levels of financial literacy our evidence contributes to the emerging literature on heterogeneity in financial decision making abilities particularly regarding retirement payouts jel d14 d91 g11 h55

financial literacy and participation in the derivatives markets we set out in this study to determine whether individuals with higher levels of financial literacy are more likely to be active participants in the derivatives markets our empirical results based upon an official national survey undertaken by the financial supervisory commission of taiwan reveal that even after controlling for stock market participation rates financial literacy represents a significant benefit to individuals since it helps them to lower the entry barriers to purchasing complex derivatives products we also find that household wealth gender residential location and diverse sources of information have significant effects on participation rates in the derivatives markets furthermore when taking into consideration issues of accessibility or measurement error the positive effects of financial literacy on derivatives market participation are found to remain largely unchanged

grid parity and self consumption with photovoltaic systems under the present regulatory framework in spain the case of the university of jaen campus abstract the cut off of any subsidy or feed in tariff that incentives the installation of new renewable energy systems which are close to the grid parity is a reality in most of the european countries but in the recent years the grid parity has worsened because of the global economic crisis in the case of spain in addition to the economic problems the photovoltaic sector has been dramatically damaged through a changeable regulatory framework an excessive bureaucracy and the inclusion of additional fees or possible back up tolls that are very prejudicial for the deployment of this sector nowadays the current spanish legislation mentions the possibility of self consumption totally or partially of the electricity generated by pv or any renewable energy systems but up to the date of this work the law that regulates the administrative technical and economic conditions for the net metering of the electrical energy produced within the consumer s network is still under a draft stage in this paper it is analyzed the case of the university of jaen where it has been identified and simulated several pv systems on the roofs and parking lots of the university campus and considering the current electrical tariffs hourly defined for the case of high power and high voltage consumers it has been done a cost and economic analysis as a result it has been obtained an average levelised cost of energy around 0 125 kwh 1 a discount payback time of 17 5 years or less a positive net present value and a nominal internal rate of return of 8 48 in the worst case beyond that it has been carried out a sensitivity analysis of the factors that have more influence in the profitability of these systems like the initial investment cost the pv electricity yield additional taxes and the variations in the electricity price market

financial literacy and mortgage equity withdrawals abstract mortgage equity withdrawals mew are correlated with covariates consistent with a permanent income framework augmented for credit constraints we assess linkages between mew and financial literacy education using the health and retirement study hrs and panel study of income dynamics psid we find that the financially literate are 3 5 percentage points less likely to withdraw housing equity via non home equity loan mortgages using the hrs while college graduates are 5 percentage points less likely than those without a high school degree in the psid among those withdrawing housing equity in the psid college graduates extract significantly less equity and are less likely to have high levels of housing leverage after doing so

does increasing women s schooling raise the schooling of the next generation the positive cross sectional relationship between the schooling of mothers and their children is substantially biased upward due to correlations between schooling and heritable ability as well as assortative mating an increase in the schooling of women would not have beneficial effects in terms of the schooling of children increased maternal schooling leads to reduced home time for mothers anticipating the consequences of investing in women s schooling requires attention to the role that schooling plays in the marriage market as well as to opportunities in the labor market for women

photovoltaic electricity production in brazil a stochastic economic viability analysis for small systems in the face of net metering and tax incentives abstract currently in addition to the search for sustainable development there is increased pressure for a change in consumption and production of energy patterns in brazil in this scenario net metering is an important mechanism fostering dissemination of small photovoltaic pv solar systems as complementary support to net metering a tax exemption is currently being offered in some brazilian states thus the objective of the present study is to analyze the impact of tax exemption on the circulation of goods and services and the returns and risks of the pv microgeneration project in four cities located in different regions of brazil belem petrolina uberaba and uruguaiana the analysis is performed using the monte carlo simulation mcs wherein uncertainties related to the financial and environmental variables are considered the results of the stochastic economic viability analysis allowed us to conclude that the exemption of tax on circulation of goods and services icms is fundamental to make pv microgeneration viable in brazil in the cities analyzed pv microgeneration presented economic unfeasibility to the investor when the icms is charged when considering the icms exemption policy the cities of petrolina and belem obtained high probabilities of viability in relation to the risk analysis pv microgeneration obtained the best results in petrolina both in terms of the condition of collection and exemption of icms there is high potential for harness solar throughout the brazilian territory however due to the current evolution stage and the productive chain of the brazilian pv industry high costs limit the expansion of this clean energy generation technology the findings of this study could assist policymakers in evaluating this incentive program highlighting that this tax exemption directly meets one of the objectives for which the icms was created which is to encourage the development of productive sectors such as pv industry

wage growth and the theory of turnover theories of turnover and wage dynamics have studied the impact of wage levels on turnover but they have failed explicitly to model the role of wage growth in predicting turnover this article presents a theory of turnover that explains why within job wage growth reduces the likelihood of worker firm separations the model determines the evolution of value among jobs that differ systematically in permanent rates of wage growth and shows that the value of high wage growth jobs increases faster with additional assumptions about the search process this proposition implies that high wage growth jobs are less likely to end

the socio technical barriers to solar home systems shs in papua new guinea choosing pigs prostitutes and poker chips over panels this study explores the socio technical barriers to solar home systems shs in papua new guinea the authors collected primary data through semi structured research interviews conducted over the course of february 2010 april 2010 respondents included government officials financiers planners commercial distributors and companies teachers and rural villagers in addition to members of civil society academics consultants and trainers these interviews were supplemented with site visits to port moresby goroka and madang and field research in the villages of akameku asaroka lufa kundiawa okifa simbu and talidig the study draws from these interviews and visits to discuss four types of barriers technical barriers relate to substandard equipment and logistical problems economic barriers include high rates of poverty misconceptions about the role of currency and lack of financing political barriers include poor institutional capacity and a government commitment to fossil fueled grid electrification social barriers encompass unrealistic expectations about what shs can provide along with jealousy theft vandalism and unfamiliarity with solar technology

inflation expectations and behavior do survey respondents act on their beliefs we compare the inflation expectations reported by consumers in a survey with their behavior in a financially incentivized investment experiment the survey is found to be informative in the sense that the beliefs reported by the respondents are correlated with their choices in the experiment more importantly we find evidence that most respondents act on their inflation expectations showing patterns consistent with economic theory respondents whose behavior cannot be rationalized tend to have lower education and lower numeracy and financial literacy these findings help confirm the relevance of inflation expectations surveys and provide support to the microfoundations of modern macroeconomic models

a theory of wage and promotion dynamics inside firms we show that a framework that integrates job assignment human capital acquisition and learning captures several empirical findings concerning wage and promotion dynamics inside firms including the following first real wage decreases are not rare but demotions are second wage increases are serially correlated third promotions are associated with large wage increases fourth wage increases at promotion are small relative to the difference between average wages across levels of the job ladder fifth workers who receive large wage increases early in their stay at one level of the job ladder are promoted quickly to the next

planning and financial literacy how do women fare many older us households have done little or no planning for retirement and there is a substantial population that seems to undersave for retirement of particular concern is the relative position of older women who are more vulnerable to old age poverty due to their longer longevity this paper uses data from a special module we devised on planning and financial literacy in the 2004 health and retirement study it shows that women display much lower levels of financial literacy than the older population as a whole in addition women who are less financially literate are also less likely to plan for retirement and be successful planners these findings have important implications for policy and for programs aimed at fostering financial security at older ages

mother s education and the intergenerational transmission of human capital evidence from college openings we examine the effect of maternal education on birth outcomes using vital statistics natality data from 1970 to 1999 we also assess the importance of four channels through which maternal education may improve birth outcomes use of prenatal care smoking marriage and fertility in an effort to account for the endogeneity of education attainment we use data about the availability of colleges in the womans country in her 17th year as an instrument for maternal education we find that higher maternal education improves infant health as measured by birth weight and gestational age it also increases the probability that a new mother is married reduces parity increases use of prenatal care and reduces smoking suggesting that may be important pathways for the ultimate effect on health our results add to the growing body of literature which suggests that estimates of the returns to education which focus only on increases in wages understate the total return

the effect of electricity consumption from renewable sources on countries economic growth levels evidence from advanced emerging and developing economies abstract this paper uses a sample of 36 countries for the time period 1990 2011 in order to examine the relationship between countries electricity consumption from renewable sources and gross domestic product gdp levels several nonparametric techniques are applied to investigate the effect of electricity consumption from several renewable sources including wind geothermal solar biomass and waste on countries gdp levels when investigating the whole sample ignoring countries economic development status the results reveal an increasing relationship up to a certain gdp level which after that point the effect of electricity consumption on gdp stabilises however when analyzing separately the emerging markets and developing economies and the advanced developed economies the results change significantly for the case of emerging market and developing economies the relationship appears to be highly nonlinear an m shape form indicating that on those countries the levels of electricity consumption from renewable sources will not result on higher gdp levels in contrast for the case of the advanced economies the results reveal an increasing nonlinear relationship indicating that higher electricity consumption levels from renewable sources results to higher gdp levels this finding is mainly attributed to the fact that in the advanced developed economies more terawatts from renewable sources are generated and consumed compared to the emerging market and developing economies which traditionally their economies rely on non renewable sources for power generation and consumption

parental investment in children s human capital in urban china the present study tests the extent of parental forgone consumption used instead to invest in children s human capital by use of intrahousehold resource allocation models using an unusual comprehensive data set for urban china there is more spending on boys aged 13 to 15 but more on girls aged 16 to 18 suggesting that standard human capital theories and traditional perceptions of gender bias do not completely explain educational expenditure decisions the evidence from urban china is consistent though with human capital models which consider parental intertemporal preferences also the findings suggest that the perceived bias in favour of sons exists weakly in contemporary urban china

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

the economic importance of financial literacy theory and evidence this paper undertakes an assessment of a rapidly growing body of economic research on financial literacy we start with an overview of theoretical research which casts financial knowledge as a form of investment in human capital endogenizing financial knowledge has important implications for welfare as well as policies intended to enhance levels of financial knowledge in the larger population next we draw on recent surveys to establish how much or how little people know and identify the least financially savvy population subgroups this is followed by an examination of the impact of financial literacy on economic decision making in the united states and elsewhere while the literature is still young conclusions may be drawn about the effects and consequences of financial illiteracy and what works to remedy these gaps a final section offers thoughts on what remains to be learned if researchers are to better inform theoretical and empirical models as well as public policy jel a20 d14 g11 i20 j26

noncognitive abilities and financial distress evidence from a representative household panel this paper provides evidence of how noncognitive abilities affect financial distress in a representative panel of households we find that people in the bottom quintile of noncognitive abilities are 10 times more likely to experience financial distress than those in the top quintile we provide evidence that this relation largely arises from worse financial choices and lack of financial insight by low ability individuals and reflects differential exposure to income shocks only to a lesser degree we mitigate endogeneity concerns using an iv approach and an extensive set of controls implications for policy and finance research are discussed received september 24 2017 editorial decision september 26 2018 by editor stijn van nieuwerburgh authors have furnished an internet appendix which is available on the oxford university press web site next to the link to the final published paper online

economic guideline about financial utilization of flat plate solar collectors fpscs for the consumer segment in the city of eskisehir abstract solar energy systems yield energy savings relative to conventional systems by considering the ecological balance although it still has barriers the most commonly used system of this type is fpsc in turkey which produces hot water by absorbing solar energy through fpscs this study is a kind of guidance about utilization of fpscs in eskisehir that concentrates on a consumer segment the aim of the study is displaying the necessity of transition to renewable energy systems in the local free markets where the place of domestic resources the data is supplied from an original hand collected survey and turkish governmental institutions such as the central bank of the republic of turkey cbrt and the turkish statistical institute turkstat that is used for a possible scenario to show how these systems can become an extensive investment and financed in the city the most significant finding is purchasing a fpsc device which is a rational and profitable investment decision for households in the economic conditions of eskisehir this type of energy system has certain costs including installation credit and annual maintenance costs however after they have been set up fpsc systems yield many ecological advantages that more than offset the associated costs such as fuel savings over the long term and exemptions from tax payments that apply to other types of fuels these advantages benefit both the environment on a global scale and the region in which the system is constructed therefore the global and local economy can improve its structure by utilizing fpscs

baby boomer retirement security the roles of planning financial literacy and housing wealth abstract we compare wealth holdings across two cohorts of the health and retirement study the early baby boomers in 2004 and individuals in the same age group in 1992 levels and patterns of total net worth have changed relatively little over time though boomers rely more on housing equity than their predecessors most important planners in both cohorts arrive close to retirement with much higher wealth levels and display higher financial literacy than non planners instrumental variables estimates show that planning behavior can explain the differences in savings and why some people arrive close to retirement with very little or no wealth

eu and russian discourse on energy relations the paper explores the dominant interpretations of the eu russian energy relations by identifying three dominant concepts around which these interpretations revolve 1 integration 2 liberalization and 3 diversification building on a detailed discourse analysis of 97 textual units produced by eu leaders and institutions and 104 documents and speeches by russian policy makers the paper argues that these three discourses differ widely in their assessment of the two partners mutual ties both in terms of the relationship s symmetry and the perceived benefits for each partner the paper comes up with two basic arguments first in spite of the shared usage of the three basic notions by both sides the interpretations of each of the discourses are widely different in the eu and in russia which causes continuous frictions and misunderstandings second and surprisingly the discourse of integration is dominant both in the eu and russia which shows that the claims about the alleged securitization of eu russian energy relations are clearly exaggerated

adoption of low cost energy efficiency measures in the tertiary sector an empirical analysis based on energy survey data this paper empirically explores factors driving the adoption of low cost energy efficiency measures in the tertiary sector which mainly consists of public and private services trade commerce and some small industries the measures considered include switching off installations or lighting managing energy use and routinely considering energy efficiency for new purchases our statistical analysis employs single and multivariate probit models relying on more than 1500 observations from a recent representative survey of the tertiary sector in germany the findings suggest that the landlord tenant dilemma holds for the adoption of all low cost energy efficiency measures considered they further imply that financial incentives such as higher energy prices accelerate the diffusion of low cost energy measures our findings also provide some evidence that knowledge transfer from the mother company to a subsidiary enhances the diffusion of low cost energy efficiency measures likewise public sector organizations are more likely to adopt energy management by and large though sectoral heterogeneity appears to have little impact on the adoption of low cost energy efficiency measures

techno economic evaluation of small hydro power plants in greece a complete sensitivity analysis abstract hydropower has by far been the most mature renewable energy resource used for electricity generation in our planet recently the investors interest was whipped up by the mass development of small hydropower shp stations as they are the most prosperous for additional hydropower penetration in developed electricity markets in greece the increasing interest for building shp stations got off the ground since 1994 ever since an enormous number of requests keep piling up in the greek regulatory authority of energy and the ministry of development with the object of creating new shp stations of total capacity over 600 mw the present work is concentrated on the systematic investigation of the techno economic viability of shp stations the study is concluded by a sensitivity analysis properly adapted for the local market financial situation in order to enlighten the decision makers on the expected profitability of the capital to be invested according to the results obtained the predicted internal rate of return irr values are greater than 18 for most shp cases analysed finally as per the sensitivity analysis carried out the installation capacity factor the local market electricity price annual escalation rate and the reduced first installation cost are found to be the parameters that mostly affect the viability of similar ventures

enabling private sector investment in microgrid based rural electrification in developing countries a review access to electricity is widely recognized as an important factor for economic and social development low rates of access particularly in remote rural areas in regions such as sub saharan africa south asia and southeast asia have led developing nations and international organizations to set ambitious goals to expand the reach of electricity decentralized solutions such as microgrids have been proposed as cost effective solutions to reaching communities located far from central grid infrastructure lack of capital from public and donor sources has severely impeded achieving access goals leading to calls for greater private sector participation in electrification activities however due to the high level of risk associated with decentralized electrification projects in low income areas marginal expected returns on investment and a lack of clear and effective public policy the private sector has not shown significant interest in participating in such projects the purpose of this paper is to review barriers to private sector participation in decentralized electrification projects and to identify solutions that have been implemented and proposed to overcome these barriers the barriers discussed include unsecure revenue streams inability to finance projects and long term project risks such as grid encroachment the range of interventions and business models reviewed include methods to secure reliable demand subsidy models risk guarantees and different revenue models this paper does not include an analysis of the effectiveness of the different interventions described future research should evaluate the relative costs and benefits of these interventions in order to provide robust policy guidance to decision makers in developing countries

review of taiwan s climate policy after copenhagen abstract the copenhagen accord in 2009 initiated new opportunities for international cooperation in reducing greenhouse gas ghg emissions the purpose of this study was to review taiwan s current climate policy and in response to the copenhagen accord to deliberate this policy in the light of new strategic thinking the study proposes a two stage approach with a dividing line in 2020 in the first stage from now until 2020 strategy should be based on cost constraints with a suggested reduction cost below 60 t co 2 and implementation of domestic ghg emissions trading scheme and reduction strategies in the second stage from 2020 and beyond action by taiwan should accord with international cooperative actions to link its domestic emissions trading scheme with the international carbon market

which renewable energy policy is a venture capitalist s best friend empirical evidence from a survey of international cleantech investors governments around the world have adopted ambitious targets to increase the share of renewable energy and reduce greenhouse gas emissions they pursue a variety of policy approaches to achieve these targets it has been a popular theme for contributions in energy policy to investigate the effectiveness of such policies this article adds a new perspective to the debate namely looking at the policy preferences of private investors in innovative clean energy technology firms we surveyed 60 investment professionals from european and north american venture capital and private equity funds and asked them to assess the effectiveness of various policies in terms of stimulating their interest to invest in innovative clean energy technologies in addition to quantitative rankings we use qualitative interview data to capture additional information on why investors prefer some policies over others the combined analysis compensates for the inherent limitations of a quantitative ranking using generic policy types the results of this exploratory analysis demonstrate that all other things being equal investors in our sample perceived feed in tariffs to be the most effective renewable energy policy the overall preference for feed in tariffs is even more pronounced among investors based in europe and with higher exposure to clean energy

modelling farmer uptake of perennial energy crops in the uk abstract the uk biomass strategy suggests that to reach the technical potential of perennial energy crops such as short rotation coppice src willow and miscanthus by 2020 requires 350 000 hectares of land this represents a more than 20 fold increase on the current 15 546 hectares previous research has identified several barriers to adoption including concerns over security of income from contracts in addition farmers perceive returns from these crops to be lower than for conventional crops this paper uses a farm level linear programming model to investigate theoretical uptake of energy crops at different gross margins under the assumption of a profit maximising decision maker and in the absence of known barriers to adoption the findings suggest that while src willow at current prices remains less competitive returns to miscanthus should have encouraged adoption on a wider scale than at present this highlights the importance of the barriers to adoption recently announced contracts for miscanthus appear to offer a significant premium to farmers in order to encourage them to grow the crops this raises the question of whether a more cost effective approach would be for government to provide guarantees addressing farmers concerns including security of income from the contracts such an approach should encourage adoption at lower gross margins

on the contribution of external cost calculations to energy system governance the case of a potential large scale nuclear accident abstract the contribution of nuclear power to a sustainable energy future is a contested issue this paper presents a critical review of an attempt to objectify this debate through the calculation of the external costs of a potential large scale nuclear accident in the externe project a careful dissection of the externe approach resulted in a list of 30 calculation steps and assumptions from which the 6 most contentious ones were selected through a stakeholder internet survey the policy robustness and relevance of these key assumptions were then assessed in a workshop using the concept of a pedigree of knowledge overall the workshop outcomes revealed the stakeholder and expert panel s scepticism about the assumptions made generally these were considered not very plausible subjected to disagreement and to a large extent inspired by contextual factors such criticism indicates a limited validity and useability of the calculated nuclear accident externality as a trustworthy sustainability indicator furthermore it is our contention that the externe project could benefit greatly in terms of gaining public trust from employing highly visible procedures of extended peer review such as the pedigree assessment applied to our specific case of the external costs of a potential large scale nuclear accident

the need for improved financial reporting of a developing country energy utility abstract some consideration has been given to regulatory and institutional reforms to facilitate sustainable development in electricity usage in papua new guinea but little attention has been paid to bringing about full compliance of financial reporting expectations of the country s main energy utility examining documentary evidence of the audit reports of the auditor general s office of papua new guinea this study considers the financial reporting compliance of png power for the period 2007 2013 and the means by which compliant reporting may be improved the results of the study reveal that the financial statements of png power are late and receive disclaimers of opinion from the auditor general s office which suggest that png power s stakeholders are not receiving accurate and reliable financial information to make informed decisions about sustainable development of electricity usage and planning in papua new guinea the study reveals that it would take little resources to improve png power s reporting which in turn could enhance national energy policy decision making and energy utility accountability

optimal financial knowledge and wealth inequality we show that financial knowledge is a key determinant of wealth inequality in a stochastic life cycle model with endogenous financial knowledge accumulation where financial knowledge enables individuals to better allocate lifetime resources in a world of uncertainty and imperfect insurance moreover because of how the us social insurance system works better educated individuals have most to gain from investing in financial knowledge our parsimonious specification generates substantial wealth inequality relative to a one asset saving model and one in which returns on wealth depend on portfolio composition alone we estimate that 30 40 percent of retirement wealth inequality is accounted for by financial knowledge

workers trust funds and the logic of wage profiles this paper defines a concept a worker s trust fund which is useful in analyzing optimal age earnings profiles the trust fund represents what a worker loses if dismissed from a job for shirking in considering whether to work or shirk a worker weighs the potential loss due to forfeiture of the trust fund if caught shirking against the benefits from reduced effort this concept is used to show that the implicit bonding in upward sloping age earnings profiles is not a perfect substitute for an explicit up front performance bond or employment fee it is also shown that the second best optimal earnings profile in the absence of an up front employment fee pays total compensation in excess of market clearing in a variety of stylized cases

a critical review of china s rapidly developing renewable energy and energy efficiency policies renewable energy and energy efficiency reee policies have far reaching implications for energy security climate change economic competitiveness pollution and human livelihood for these reasons reee has become a national priority for the chinese government particularly since 2005 this paper aims to critically review china s reee policies in six sectors electricity industry transportation buildings and local government in addition to examining the progress china has made in the development and implementation of reee policies this review also identifies limitations and room for improvement finally five policy recommendations are presented

access to electricity in small island developing states of the pacific issues and challenges abstract energy poverty is widespread in small island developing states sids of the pacific it is estimated that 70 percent of pacific islander households do not have access to electricity which is equivalent to access rates in sub saharan africa and slightly below the average for low income countries pacific sids face unique challenges in expanding access to electricity given that their populations are spread across tens of thousands of islands governments and development partners in pacific sids continue to prioritise development of electricity grids as is evident in ongoing subsidisation of grid based power consumption and the establishment of ambitious grid based renewable energy targets this paper argues that traditional approaches to rural electrification which prioritise grid extension are not suited to the pacific islands region increased funding should be directed by both governments and development partners towards rural electrification especially in off grid areas where isolated systems are more appropriate institutional reform is also important regulatory reform is needed for power utilities to extend electricity grids into rural areas institutional arrangements that facilitate the sustainable operation and maintenance of off grid systems also need to be established past donor and government funded off grid rural electrification projects have rarely been sustainable alternative approaches involving payment of output based subsidies to energy service companies are worth exploring although will only succeed where sound regulatory arrangements are in place

economic and socio economic assessment methods for ocean renewable energy public and private perspectives this paper provides a comprehensive review of the current state of the art of the economics and socio economics of ocean renewable energy ore the many ways in which the viability and impacts of an ore project are assessed and an analysis of the current weaknesses issues or inappropriateness of the metrics and methodologies used in their definition and presentation the outcomes of this paper are anticipated to benefit the ore and wider renewable sector as a whole the review revealed that for the most part the current study of economics and socio economics of ore remain separate and discrete areas of research the economic methods utilised appear to be comprehensive but are limited to project or private investor level the methods identified for socioeconomic assessment fall between traditional and now routine environmental assessment approaches and more novel holistic approaches such as ecosystem services and life cycle assessment the novel section of the paper explored the connectivity between the economics and socio economics of ore in relation to project developments and policy planning a visualisation method was created of concentric rings intersected by related axis of economic socio economic and environment and enabled the examination of the benefits arising from the connectivity between the two spheres the concept of sustainable development process and the integration of environmental assessment for ore was also explored and how it responds to differing stakeholder aspirations and interpretations the analysis revealed that there was a divergence between public and private economic and socioeconomic assessments for ore environmental assessment is primarily a public responsibility but with significant inputs from the private developer involved while economic assessments are conducted primarily by the developer and or investor at their own behest however the two spheres of economic and socio economic for ore are highly connected and synergistic and must be examined in a holistic manner

what accounts for the variation in retirement wealth among u s households even among households with similar socioeconomic characteristics saving and wealth vary considerably life cycle models attribute this variation to differences in time preference rates risk tolerance exposure to uncertainty relative tastes for work and leisure at advanced ages and income replacement rates these factors have testable implications concerning the relation between accumulated wealth and the shape of the consumption profile using the panel study of income dynamics and the consumer expenditure survey we find little support for these implications the data are instead consistent with rule of thumb mental accounting or hyperbolic discounting theories of wealth accumulation jel di d91 e21

are fluctuations in energy consumption per capita transitory evidence from a panel of pacific island countries this study applies the panel stationarity test developed by carrion i silvestre et al 2005 breaking the panels an application to gdp per capita econometrics journal 8 159 175 to examine the stationarity of energy consumption per capita for a panel of 13 pacific island countries over the period 1980 2005 this test has the advantage that it allows for multiple structural breaks at unknown dates that can differ across countries and can account for all forms of cross sectional correlation between countries the conclusion from the study is that energy consumption per capita in approximately 60 of countries is stationary and that energy consumption per capita for the panel as a whole is stationary the study offers several suggestions for modelling energy consumption and policy making in the pacific islands

what do twins studies reveal about the economic returns to education a comparison of australian and us findings conventional estimates of rates of return to education are constrained because they are unable to isolate the returns to schooling from the contribution of individual ability and the influence of family background potentially studies using a sample of twins may overcome these problems monozygotic twins are genetically identical and if they have been reared together share the same family background differences in income between identical twins can therefore be associated with differences in the amount of education they have undertaken in order to estimate the independent influence of education comparisons of such estimates with estimates made from a sample of dizygotic twins who are genetically similar but not identical and who are also reared together may permit evaluation of the biases associated with ability and family background in conventional estimates of the return to education in an important paper jere behrman et al 1977 analyzed data from a sample of male world war ii veteran twins and found that of the overall rate of return to schooling of 8 percent 2 7 percentage points could be attributed to schooling per se 3 2 percentage points could be attributed to genetic factors and 2 1 percentage points could be attributed to shared family environment in a recent paper however orley ashenfelter and alan krueger 1994 have estimated the economic returns to education using data on a new sample of twins which permitted them to adjust their estimate for omitted ability variables and measurement error on this basis they find that family and genetic effects make virtually no contribution to the returns to schooling measurement error however biases the estimated return to schooling downward the findings of ashenfelter and krueger 1994 are very different from previous work in this field and there is now some confusion as to what analysis of twins data really reveals about the economic returns to schooling ashenfelter and krueger s results are based on analysis of data for a sample of 298 individuals 149 pairs of identical twins who attended a twins festival in 1991 they remark at the end of their paper only additional data collection is likely to lead to better estimates of the returns to schooling p 1171

economic evaluation of short rotation coppice systems for energy from biomass a review abstract since economic profitability is the most important factor for the adoption of short rotation coppice src for energy from biomass our objective was to analyze and summarize published knowledge about the economic evaluation of src of 37 studies 43 reported economic viability of src in comparison to a reference system whereas 19 stated economic disadvantages of src and 38 reported mixed results depending on the underlying assumptions we found a wide variety of underlying assumptions underlying costs process chains and methods used to evaluate src systems of the 37 studies 8 used static approaches of capital budgeting 84 used dynamic approaches and 8 applied approaches in which uncertainties were taken into account due to the long term nature of investment in src and therewith the uncertain development of sensitive assumptions approaches which consider uncertainties were best suited for economic evaluation the profitability of src was found to be most sensitive to the price for biomass and biomass yield but site specific biomass data was lacking despite the wide variation within each cost unit costs for land rent harvesting chipping and establishment consistently made up the largest proportion of overall costs and should therefore be chosen carefully we close with suggestions for improving the economic evaluation of src and enhancing traceability and comparability of calculations

an investigation of the labor market earnings of panamanian males evaluating sources of inequality this paper presents empirical evidence on the determinants of labor market earnings and inequality for males in panama using newly available microdata we estimate earnings equations based on the measurement framework of mincer 1974 and compare them with those for other countries at various stages of economic development we present evidence on two aspects of inequality in less developed economies labor market segmentation and social stratification we present tests of the segmentation hypothesis including several of the dual labor market hypotheses and discuss their inherent ambiguity we also present evidence on the importance of family background for earnings determination and educational attainment

asset life and pricing the use of electricity transmission infrastructure in chile abstract beyond the different approaches to set regulated prices for the use of infrastructure a key parameter to determine regulated tariffs is the concept of asset life and how it changes with changes in the economic and regulatory context which determines the optimal infrastructure investment and replacement policies in this paper we look at the effects that changes in demand the presence of substitutes and complements the regulatory framework both a pro or an anticompetitive framework scale economies and the investment planning horizon have on the economic service life of an asset and the tariffs for its use we find that as the electric industry becomes more competitive a negative effect on the economic service life of electric electricity transmission should be expected also numerical experiments illustrate an inverse relation between scale economies on investment and the esl of electricity transmission infrastructure further we look at the biases on optimal investment that happen when optimal plans do not observe the life cycle of the investments and the esl of the equipment as well as the inconsistency and biases on optimal investment and replacement policies that might result when the social planner optimal investment plan lacks of a long term commitment

endowments and the allocation of schooling in the family and in the marriage market the twins experiment 03 we show how comparisons between the within twin correlations of human capital outcomes across identical and nonidentical twins can be used to identify the variability in the individual specific component of endowments and the responsiveness of schooling to individual specific endowments in the family and in the marriage market even when schooling is measured with error estimates from two twins samples indicate that 27 42 percent of the variance in log earnings obesity is due to variability in individual specific endowments allocations of schooling reinforce specific endowments and individual specific earnings endowments of men and their wives schooling are negatively associated

the politico economics of electricity planning in developing countries a case study of ghana abstract off grid technologies are increasingly being proposed as a way of ensuring cost efficient universal access to electricity in many developing countries however many un electrified communities would prefer access to electricity via the national grid rather than off grid technologies electricity planning based on cost efficiency alone could therefore be undermined by political pressure from discontented communities that are assigned off grid technologies using a case study of un electrified communities in ghana we develop an electricity planning algorithm based on hierarchical lexicographic programming and consider specifications where the priorities are adjusted to give weight to 1 cost efficiency and 2 political economy considerations so that communities with larger populations and therefore votes are given priority in terms of grid electrification the results emphasise the need to incorporate the political economy considerations in the national planning of universal electrification showing significant regional differences in terms of where grid extensions ought to be placed incorporating a political economy perspective in national planning also suggests that the most important policy trade offs shift from considering the grid versus off grid balance to focussing more on the effectiveness of grid investment in providing universal access

the analysis on photovoltaic electricity generation status potential and policies of the leading countries in solar energy abstract energy which is the main agenda of our world is crucially important for the people many countries frequently held meetings and discussions with energy agenda these countries are working to balance the energy demand and supply for finding the solution are researched researches should be attempted to present a more efficient way to use energy as well as renewable energy resources effectively photovoltaic energy power systems take place as the most dominant source among renewable energy technologies the most important reason is that it is unlimited and clean energy of the solar power systems many studies show that photovoltaic power systems will have an important share in the electricity of the future in this study to generate electricity from solar energy using photovoltaic systems have a leading position in some european countries united states of america china and japan s current status and future policies will be analyzed in various comments were made

energy policy and cooperation in southeast asia the history challenges and implications of the trans asean gas pipeline tagp network this article explores the proposed multibillion dollar trans asean gas pipeline tagp network in southeast asia focusing on the interests that have promoted the tagp and why based on extensive field research textual analysis of government reports and more than 100 research interviews at government institutions multilateral development banks universities consulting firms energy companies and nongovernmental organizations this article assesses the challenges facing the tagp in terms of promotion implementation and operation it explores the genesis of the tagp project and the drivers pushing southeast asian investment in natural gas with a special emphasis on the development needs of the region it also investigates the numerous technical economic legal political social and environmental impediments to the tagp project the article concludes that the rhetoric of regional energy cooperation touted by the association of southeast asian nations asean does not match its actual practice and that in many cases discussions of regionalism and energy security are intended to obscure opportunistic thinking within individual countries

independent regulatory agencies and rules harmonization for the electricity sector and renewables in the mediterranean region the paper analyses the existing regulatory framework for the electricity and renewables sectors and the role of regulatory agencies in northern africa and middle east countries under the promotion by the european union using data collected through an original survey directed at regulators ministry departments and energy companies of the southern mediterranean the study is aimed at assessing the extent of agencies independence looking at three main dimensions of independence regulatory instruments available to regulators and decision making autonomy regulators organizational autonomy and regulators accountability results show that those countries having established an independent regulator have a more credible regulatory framework than those countries in which such a body does not exist in particular the analysis shows that turkey croatia and jordan have defined a regulatory framework that limits administrative expropriation and consequently creates an environment more suitable for attracting investments in the electricity and renewables sector on the institutional ground this is probably related with the harmonization of regulatory standards promoted by the european union through the neighboring policy for the jordan case and the membership perspective in the turkish and croatian cases

energy and economic analysis for large scale integration of small photovoltaic systems in buildings the case of a public location in southern spain abstract the integration of grid connected pv systems into buildings or public areas is one of the most usual applications of the photovoltaic solar energy in developed countries and it is being highly promoted by several european governments in this paper it has been evaluated the photovoltaic potential of the campus of the university of jaen and it has been defined possible areas where the pv systems could be installed according to power requirements space possibilities the electrical configuration of the campus and some social integration requirements too the definition of the pv potential together with a technical analysis for the calculation of the energy generated is the previous step for carrying out an economic and cost analysis in order to certify the profitability of these systems in general particularizing the study for the case of this university located in southern spain the pv electricity cost generated has been calculated through the concept levelised cost of electricity lcoe where in our case is estimated to be around 0 13 0 14 kwh 1 the results obtained in this economic analysis recommend the implementation of pv grid connected systems pvgcs as the internal rate of return reaches a maximum value of 6 21 the net present value is positive and the discounted payback time is around 16 years an additional sensitive analysis shows the influence that some parameters have on the lcoe specially the initial investment the energy yield and the nominal discount rate

reform despite politics the political economy of power sector reform in fiji 1996 2013 abstract attempts to reform the electricity sector in developing countries have achieved mixed results despite the implementation of similar reforms in many developed countries and concerted effort by donors to transfer reform models in many cases political obstacles have prevented full and effective implementation of donor promoted reforms this paper examines the political economy of power sector reform in fiji from 1996 to 2013 reform has been pursued with political motives in a context of clientelism policy inconsistency and reversal is explained by the political instability of ethnic based politics in fiji modest success has been achieved in recent years despite these challenges with fiji now considered a model of power sector reform for other small islands developing states sids in the pacific the experience demonstrates that reform is possible within difficult political environments but it is challenging takes time and is not guaranteed the way in which political motives have driven and shaped reform efforts also highlights the need for studies of power sector reform to direct greater attention toward political drivers behind reform

risk adjusted financial costs of photovoltaics recent research shows significant differences in the levelised photovoltaics pv electricity cost calculations the present paper points out that no unique or absolute cost figure can be justified the correct solution is to use a range of cost figures that is determined in a dynamic power portfolio interaction within the financial scheme support mechanism and industry cost reduction the paper draws attention to the increasing role of financial investors in the pv segment of the renewable energy market and the importance they attribute to the risks of all options in the power generation portfolio based on these trends a former version of a financing model is adapted to project the energy mix changes in the eu electricity market due to investors behaviour with different risk tolerance aversion the dynamic process of translating these risks into the return expectation in the financial appraisal and investment decision making is also introduced by doing so the paper sets up a potential electricity market trend with the associated risk perception and classification the necessary risk mitigation tasks for all stakeholders in the pv market are summarised which aims to avoid the burden of excessive risk premiums in this market segment

the effects of education and family planning programs on fertility in indonesia abstract numerous studies indicate that female education is a major determinant of fertility and that the estimated effects are large relative to other variables including family planning program variables there are however two serious deficiencies in the research relating educational attainment to fertility that could give rise to invalid inferences first many public programs including health and family planning programs may influence a woman s decisions about education and these indirect programmatic effects might be large second nearly all existing studies of the impacts of education on fertility assume that a woman s educational attainment is exogenous education could be serving as a proxy for such unobservable determinants as ability motivation and parental background as these factors most likely are important determinants of a woman s educational attainment we use the 1993 indonesian family life survey to compare the estimated impacts of education on fertility from a simple model tha

economic analysis of pv systems on buildings in sicilian farms abstract the photovoltaic sector in italy in recent years has experienced a rapid growth also in the primary sector thanks to substantial incentives guaranteed by energy policies simultaneous reduction of investment costs and tax benefits in order to better understand the growth of the pv industry in italian primary sector the aim of this paper has been to evaluate the economic convenience of four pv systems on farm buildings located in four different farms of the north western coast of sicily and realized during the second and fourth italian feed in schemes for each feed in scheme it has been considered a pv plant that sells the electricity to the grid and another in which the energy generated is consumed entirely by the farm the results show a clear convenience to the realization of investments both with the current market conditions and at the variation of the feed in tariff or the investment costs

the diagnosis of an electricity crisis and alternative energy development in pakistan abstract the electricity sector in pakistan is currently facing the formidable challenges of an insufficient installed capacity a suboptimal infrastructure circular debt and revenue shortage all of these problems hamper socioeconomic activities this paper diagnoses the overall condition of the electricity sector as well as the potential and recent progress in the implementation of alternative energy projects in the context of the targets set in the national energy security plan nesp the assessment reveals the unsatisfactory overall progress of the implementation of the nesp in general and alternative energy in particular we assess that if the short term measures contained in the nesp have been adequately executed were enough to bridge the existing electricity supply demand gap and the country might not be facing an ongoing electricity crisis further we investigated the specific alternative energy policy issues that hinder this sector s development in pakistan we conclude that fuel diversification by means of the maximum utilisation of alternative energy resources would help in solving the crisis and would also furnish the long term energy needs of the country finally we recommend a comprehensive strategy for revamping the electricity sector and developing the alternative energy resources needed to tackle the ongoing electricity crisis in pakistan

economic evaluation of miscanthus production a review this paper reviews the peer reviewed literature dealing with the economics of miscanthus cultivation to identify factors influencing the adoption of miscanthus and to reveal shortcomings in research in total 51 studies have been identified for this review the majority of these publications are recent i e the majority is published after 2009 and concern case studies in europe particularly the uk and ireland and north america this review reveals that the economic viability of miscanthus depends on largely uncertain assumptions especially concerning yields 10 48 t dry matter per ha and prices 48 134 t dry matter but also concerning the lifespan 10 20 years and different cost items a lack of established markets high establishment costs and uncertainties arising to a large extent from the long term commitment are identified as major barriers to miscanthus adoption in addition the level of support for miscanthus production e g via subsidies is identified as crucial for miscanthus profitability but is found to be highly heterogeneous across countries next to diversity in agronomic and economic assumptions also the assessment criteria and research techniques used to investigate the profitability of miscanthus differ widely while the net present value criterion was most frequently used we identify a lack of approaches that account for risks and uncertainties which seem to potentially play a critical role in the uptake of miscanthus by farmers

the framing of unconventional natural gas resources in the foreign energy policy discourse of the russian federation the advent of unconventional resources of natural gas has altered the order on global as well as continental gas markets with rising liquidity the position of established dominant suppliers is eroding we focus on the initial response of russia the leading supplier of natural gas to europe to the new situation building the research on unit level constructivism and discourse analysis we use frame analysis to reveal what image of unconventional resources was constructed in russian foreign energy policy discourse fepd in the period between 2009 and 2011 when the unconventional revolution did not yet have any sharp contours we conclude that in russian fepd the unconventionals are considered as a distinctive and inferior source of energy compared to conventional natural gas emphasis is put on their economic irrationality and environmental hazards the bottom line of the discourse is the idea that there is a choice between conventional and unconventional sources with this choice being framed as one between good and bad or right and wrong

reserve reporting in the united states coal industry united states energy policymaking can be better supported with accurate and consistent data on coal reserves both in the public and private sectors in particular reserve data for coal and other energy resources should be directly comparable so that decision makers can easily understand the relationship among available resources long term policy and investment choices regarding energy security the environment and resource allocation depend on accurate information but existing and easily available data on the magnitude of geologically environmentally economically socially and legally accessible coal reserves are of insufficient quality to guide such decisions even still these data are often presented for use in policy and energy analysis currently coal reserves are overstated relative to competitor energy resource reserves in part because coal reporting standards have historically been more liberal and vague than standards for resources like natural gas overstating the marketable coal resource could lead to inefficient allocation of limited capital investment that can be difficult to reverse us government bodies like the energy information administration united states geological survey securities and exchange commission and bureau of land management can help correct deficiencies by clarifying standards and collecting data that are relevant for decision makers such as energy based reserve information

the effects of perceived and actual financial literacy on financial behaviors a combined measure of financial literacy that includes both a test score of actual financial literacy and a self rating of overall financial literacy is used in this study we find that the combined measure appears to provide greater understanding about how financial literacy affects financial behaviors a large national survey of u s adults and households n 28 146 was used to investigate how this overall financial literacy is likely to change financial behaviors across five financial topics credit cards investments loans insurance and financial advice for each topic we include 4 5 financial behaviors 22 in total to demonstrate the consistency of the findings within and across topics although we are unable to identify a causal relationship the results from the probit analysis show that both actual and perceived financial literacy appear to influence financial behaviors and that perceived financial literacy may be as important as actual financial literacy jel d14 g00
