the role of local nonfarm activities and migration in reducing poverty evidence from ethiopia kenya and uganda by using cross sectional data from ethiopia kenya and uganda this article estimates the determinants of the participation in local nonfarm activities and migration at the individual level and then estimates the determinants of farm and nonfarm income the results indicate that schooling and local language ability increase participation in local nonfarm activities and migration schooling also is found to increase nonfarm income at the household level but not farm income we also find that farm household members from low potential agricultural areas are more likely to participate in local nonfarm activities and migration than those from high potential agricultural areas thus the results suggest that local nonfarm activities and migration offer employment opportunities for workers from low potential agricultural areas indeed the nonfarm activities and migration is likely to provide an important pathway to reduce poverty in low potential agricultural areas in east africa

semi nonparametric estimates of interfuel substitution in u s energy demand abstract this paper focuses on the demand for crude oil natural gas and coal in the united states in the context of two globally flexible functional forms the fourier and the asymptotically ideal model aim estimated subject to full regularity using methods suggested over 20 years ago by gallant and golub gallant a ronald and golub gene h imposing curvature restrictions on flexible functional forms journal of econometrics 26 1984 295 321 and recently used by serletis and shahmoradi serletis a shahmoradi a 2005 semi nonparametric estimates of the demand for money in the united states macroeconomic dynamics 9 542 559 in the monetary demand systems literature we provide a comparison in terms of a full set of elasticities and also a policy perspective using for the first time parameter estimates that are consistent with global regularity

sustainable development and corporate performance a study based on the dow jones sustainability index the goal of this paper is to examine whether business performance is affected by the adoption of practices included under the term corporate social responsibility csr to achieve this goal we analyse the relation between csr and certain accounting indicators and examine whether there exist significant differences in performance indicators between european firms that have adopted csr and others that have not the effects of compliance with the requirements of csr were determined on the basis of firms included in the dow jones sustainability index djsi and specific accounting indicators were applied to measure performance for the purposes of this study we selected one group of firms belonging to the djsi and another comprised of firms quoted on the dow jones global index djgi but not on the djsi the sample was made up of two groups of 55 firms studied for the period 1998 2004 empirical analysis supports the conclusion that differences in performance exist between firms that belong to the djsi and to the djgi and that these differences are related to csr practices we find that a short term negative impact on performance is produced

weighing the costs and benefits of state renewables portfolio standards in the united states a comparative analysis of state level policy impact projections abstract state renewables portfolio standards rps have emerged as one of the most important policy drivers of renewable energy capacity expansion in the u s as rps policies have been proposed or adopted in an increasing number of states a growing number of studies have attempted to quantify the potential impacts of these policies focusing primarily on cost impacts but sometimes also estimating macroeconomic risk reduction and environmental effects this article synthesizes and analyzes the results and methodologies of 31 distinct state or utility level rps cost impact analyses completed since 1998 together these studies model proposed or adopted rps policies in 20 different states we highlight the key findings of these studies on the projected costs of state rps policies examine the sensitivity of projected costs to model assumptions evaluate the reasonableness of key input assumptions and suggest possible areas of improvement for future rps analyses we conclude that while there is considerable uncertainty in the study results the majority of the studies project modest cost impacts seventy percent of the state rps cost studies project retail electricity rate increases of no greater than 1 nonetheless there is considerable room for improving the analytic methods and therefore accuracy of these estimates

rural income dynamics and poverty reduction in thai villages from 1987 to 2004 this article aims to examine the factors contributing to the increase in household income and the corresponding reduction in poverty in rural thai villages from 1987 to 2004 by employing household panel data it is found that there has been a significant structural shift of household income away from farm to nonfarm income sources as well as a reduction in the income gap and the difference in poverty incidence between favorable and unfavorable regions such decreases in poverty and its regional gap have been associated with the declining importance of income accrued to farm land measured by farm size and the availability of irrigation and with the increasing importance of human capital measured by the proportion of working members who have graduated from post lower secondary schools such findings indicate that the success in rural poverty reduction in thailand has resulted from the development of the rural nonfarm sector coupled with the improvement of the schooling levels of the rural population

the value relevance of reputation for sustainability leadership this study investigates whether the market valuation of the two summary accounting measures book value of equity and net income is higher for firms with reputation for sustainability leadership when compared to firms that do not enjoy such reputation the results are interpreted through the lens of a framework combining signalling theory and resource based theory according to which firms signal their commitment to sustainability to influence the external perception of reputation a firm s reputation for being committed to sustainability is an intangible resource that can increase the value of a firm s expected cash flows and or reduce the variability of its cash flows our findings are according to expectations and show that the net income of firms with good sustainability reputation has a higher valuation by the market when compared to their counterparts

economic mobility and poverty dynamics in developing countries this study provides an introduction to this special issue of the journal of development studies on economic mobility and poverty dynamics in developing countries in addition to providing a conceptual framework it outlines how the contributions fit into the extant literature a series of regularities emerge across these studies the poor consist of those who are always poor poor at all dates and those who move in and out of poverty with the latter group tending to be strikingly large such movements in and out of poverty are apparent when looking at poverty in either absolute or relative terms changes in returns to endowments can be a potent source of increased incomes finally seemingly transitory shocks can have long term consequences the study concludes by drawing out the policy implications of these regularities

separability functional form and regulatory policy in models of interfuel substitution abstract counter intuitive results such as positive own price elasticities have been found in some studies of interfuel substitution this paper examines three possible reasons for this problem first including energy materials in petroleum and coal aggregates is found to contribute to incorrect signs second the mathematical properties of the translog function contribute to concavity violations in contrast the linear logit model of cost shares is found to provide more sensible estimates of own price elasticities across alternative model specifications finally natural gas curtailment policies and environmental regulations are found to be significant factors influencing us industrial fuel demand although omission of these factors does not directly contribute to curvature violations

green revolution land reform and household income distribution in the philippines income of agricultural households consists of returns to labor capital and land from farming supplemented mainly by labor earnings from nonfarm sources agricultural technology affects farmers income through its effect on factor demands and factor prices which in turn induce changes in the allocation of farmers own resources to different uses income from farming is also affected by village institutions such as land tenure which governs the distribution of income between landlords and tenants as well as resource allocations

impact of deployment of renewable portfolio standard on the electricity price in the state of illinois and implications on policies abstract the renewable portfolio standard rps of the state of illinois specifies a schedule for the fraction of electricity produced from wind to be phased in through 2025 the price of electricity due to implementation of rps in order to achieve a six year payback on investment on new wind farms was estimated for six scenarios that examined the effect of electricity consumption growth rate production tax credit of 0 022 kw h or unrestricted investment tax credit of 30 and projected changes in installed project costs in all cases the electricity price was found to be dominated by the installed project cost capital cost thus any policy that affects the capital cost directly or indirectly would have a significant effect on the electricity price whereas investment tax credit has a direct effect policies that encourage technology improvement and improve transmission lines would have a similar effect of lowering the capital cost carbon tax on the other hand would increase the electricity price to the consumers although it offers other benefits

a dynamic analysis of interfuel substitution in u s industrial energy demand using data for 1960 92 to analyze interfuel substitution in the u s industrial sector a dynamic linear logit model is shown to provide superior global properties than a comparable dynamic translog model confirming earlier static results by t j considine 1989 the linear logit model provides a direct unbiased estimate of the rate of dynamic adjustment indicating a median response lag of less than two years excluding fuels used for nonenergy purposes yields larger estimates of the price elasticities for coal and oil and indicates generally greater potential for interfuel substitution than when using aggregate data

can deployment of renewable energy put downward pressure on natural gas prices abstract high and volatile natural gas prices have increasingly led to calls for investments in renewable energy one line of argument is that deployment of these resources may lead to reductions in the demand for and price of natural gas many recent us based modeling studies have demonstrated that this effect could provide significant consumer savings in this article we evaluate these studies and benchmark their findings against economic theory other modeling results and a limited empirical literature we find that many uncertainties remain regarding the absolute magnitude of this effect and that the reduction in natural gas prices may not represent an increase in aggregate economic wealth nonetheless we conclude that many of the studies of the impact of renewable energy on natural gas prices appear to have represented this effect within reason given current knowledge these studies specifically suggest that a 1 reduction in us natural gas demand could lead to long term average wellhead price reductions of 0 8 2 and that each megawatt hour of renewable energy may benefit natural gas consumers to the tune of at least 7 5 20

cost effectiveness as energy policy mechanisms the paradox of technology neutral and technology specific policies in the short and long term when choosing policy mechanisms to design and deploy energy policies policymakers typically seek cost effective ones linking cost effectiveness to the lowest cost of support for res e generation and or consumer costs the objectives of this paper are to analyze the cost effectiveness of renewable portfolio standards rps feed in tariffs fit and auctions in the short and long term considering both technology neutral and technology specific approaches results show that rps and auctions are more cost effective than feed in tariffs fit in the short term if cost effectiveness is defined as minimizing consumer costs also if one or more emerging technologies with higher levelized life cycle costs lcc low cumulative production and high experience elasticity are considered in the pool of res e policy design a technology neutral approach in the short term could lock out these emerging technologies avoiding a long term lcc reduction in this case a technology specific policy used in the short term would reflect lower total generation policy costs in the long term if compared with a technology neutral policy in both short and long term this paper calls this phenomenon the paradox of technology neutral and technology specific policies in the long term considering the results this paper suggests a mix of technology neutral and technology specific policies using rps or auction mechanisms to promote res e

a dynamic analysis of interfuel substitution for swedish heating plants abstract this paper estimates a dynamic model of interfuel substitution for swedish heating plants we use the cost share linear logit model developed by considine and mount considine t j mount t d 1984 the use of linear logit models for dynamic input demand systems review of economics and statistics 66 434 443 all estimated own price elasticities are negative and all cross price elasticities are positive the estimated dynamic adjustment rate parameter is small however increasing with the size of the plant and time indicating fast adjustments in the fuel mix when changing relative fuel prices the estimated model is used to illustrate the effects of two different policy changes

do sustainable companies have a better financial performance a study on brazilian public companies abstract increasingly companies are taking initiatives to mitigate the negative social and environmental impacts to address the emerging needs of society in the financial realm stock markets created indices to offer investors the option to prioritize sustainable companies in brazil the initiative came from the sao paulo stock exchange by releasing the corporate sustainability index in this paper we analyze the financial and economic performance of companies listed in the corporate sustainability index in comparison with the performance of companies listed in the sao paulo stock exchange index for that profitability and liquidity ratios were calculated and statistical tests specifically cluster and nonparametric analysis were performed to validate possible trends similarities or differences observed in each group of companies based on our analysis we found no evidence of economic and financial performance differences between companies from each of the studied indices in fact our findings show that other characteristics such as sectorial classification have more influence on firms economic and financial performance than their investments in sustainable initiatives the research contributes to the body of knowledge in the field of corporate sustainability by utilizing a different methodology than similar studies have used incorporating different accounting ratios and new statistical analyses of data from the emerging brazilian market

the role of energy conservation and natural gas prices in the costs of achieving california s renewable energy goals abstract this paper develops an econometric forecasting system of energy demand coupled with engineering economic models of energy supply the framework is used to quantify the energy and environmental impacts of renewable and natural gas based electricity power generation in california considering the role of on going energy conservation efforts and incorporating different natural gas price scenarios over the forecast horizon 2011 2035 the results indicate that relative to a business as usual scenario of continuing to rely on imported electricity to meet future demand california s renewable portfolio standard rps of 33 renewables by 2020 will increase electricity rates by over 10 however the rps will also provide substantial annual savings in carbon dioxide emissions equal to 40 million metric tons in 2020 continuing non price induced energy conservation at the historical rate will only result in a marginal reduction in electricity rates although lower electricity use means that substantial savings are nonetheless achieved in electricity expenditures in addition continuing trend energy conservation leads to substantial savings in carbon dioxide emissions like the rps developing domestic natural gas generation also leads to rate increases and reductions in carbon dioxide emissions relative to the baseline however these impacts are minor compared to the rps scenario

interfuel substitution a meta analysis interfuel substitutability has been of longstanding interest to the energy economics and policy community however no quantitative meta analysis has yet been carried out of this literature this paper fills this gap by analyzing a broad sample of studies of interfuel substitution in the industrial sector manufacturing industry or subindustries or macro economy of a variety of developed and developing economies publication bias is controlled for by including the primary study sample size in the meta regression results for the shadow elasticities of substitution between coal oil gas and electricity for forty six primary studies show that at the level of the industrial sector there are easy substitution possibilities between all the fuel pairs with the exception of gas electricity and coal electricity substitution possibilities seem more constrained at the macro level and less constrained in sub industries estimates also vary across countries publication bias does not seem to be present but model and data specification issues very significantly affect the estimates derived by each individual study estimates from cross section regressions are generally largest fixed effects panel estimates intermediate in magnitude and time series estimates are mostly much smaller econometric research suggests that the fixed effects estimates are likely the best among the existing studies though biased downwards

implementing renewable energy portfolio standards the good the bad and the ugly in a two state comparison abstract understanding how household practices with regard to energy usage change and how to most effectively encourage the adoption of technologies that utilize renewable energy sources at the residential scale are important issues for addressing the environmental impacts of energy use here the social practices model spaargaren 2003 is applied to examine solar technology adopters in two u s states who were interviewed about adopting residential solar electric technology and specifically about their experiences with the rebate and incentive programs available to them examining the policies and interrogating their potentially unintended consequences from the perspective of the user sheds light on how residential solar incentive programs act as systems of provision shaping the practices of solar technology adopters in hopes of improving these incentive programs and effectively encouraging increased residential solar technology adoption findings suggest that feed in tariffs offer additional positive outcomes related to broadening the context for adoption and encouraging future energy conservation while size restrictions wholesale pricing in net metering agreements and inconsistent policy mechanisms across utilities in the same state all have potentially unintended negative consequences utilizing a perspective attentive to social practice offers a means of improving the design and implementation of energy policy

the associations of soil fertility and market access with household income evidence from rural uganda abstract this study attempts to identify the major factors affecting farm and nonfarm income by using panel data of 894 rural households interviewed in 2003 and 2005 in rural uganda we supplement the panel data with household level soil fertility data and road distance data to the nearest urban center on three road types tarmac loose surface and dirt roads the results suggest that soil fertility measured by the soil organic matter som content is positively associated with crop income but not with livestock and nonfarm income we also find that the total road distance to the nearest urban center and the road quality have strong negative associations with the crop income

transformation of the rural economy in the philippines 1988 2006 abstract this research explores the changing structure of the rural economy in the philippines from 1988 to 2006 we found that the expansion and upgrade of infrastructure such as electricity and roads and investment in secondary and tertiary education are important factors that induced the economic transformation of the rural economy the importance of higher education as an entry requirement to the nonfarm labor market has declined over time indicating that the rural nonfarm sector has been increasingly providing employment opportunities to the unskilled and the uneducated who form the bulk of the rural poor

the economic costs of reducing greenhouse gas emissions under a u s national renewable electricity mandate the electricity sector is the largest source of greenhouse gas emissions ghgs in the u s many states have passed and congress has considered renewable portfolio standards rps mandates that specific percentages of electricity be generated from renewable resources we perform a technical and economic assessment and estimate the economic costs and net ghg reductions from a national 25 percent rps by 2025 relative to coal based electricity this policy would reduce ghg emissions by about 670 million metric tons per year 11 percent of 2008 u s emissions the first 100 million metric tons could be abated for less than 36 metric ton however marginal costs climb to 50 for 300 million metric tons and to as much as 70 metric ton to fulfill the rps the total economic costs of such a policy are about 35 billion annually we also examine the cost sensitivity to favorable and unfavorable technology development assumptions we find that a 25 percent rps would likely be an economically efficient method for utilities to substantially reduce ghg emissions only under the favorable scenario these estimates can be compared with other approaches including increased r d funding for renewables or deployment of efficiency and or other low carbon generation technologies

the use of linear logit models for dynamic input demand systems this paper demonstrates that a linear logit model with appropriate constraints can be used to specify a system of cost share equations that satisfy neoclassical economic conditions unlike many other flexible functional forms the logistic function is particularly well suited for incorporating dynamic adjustment mechanisms the empirical results suggest that the use of static models overstates short run own price elasticities and understates the corresponding long run price effects

optimal design of subsidy to stimulate renewable energy investments the case of china this paper proposes a real options model for estimating the optimal subsidy for renewable energy power generation project by using stochastic process to describe the market price of electricity co2 price and investment cost two indicators i e project value and threshold value are used to derive the optimal subsidy the least squares monte carlo simulation method is used to solve the model the proposed model is used to empirically evaluate the optimal level of subsidy for solar photovoltaic power generation in china the results show that carbon emission trading scheme helps reduce subsidy unit generating capacity market price of electricity co2 price and the volatility of investment cost are negatively related with subsidy whereas investment cost and the volatility of electricity price and co2 price are positively related with subsidy it is suggested that chinese governments take some measures e g promoting technological progress establishing a nationwide carbon emission trading market promoting the competition in renewable energy industry as well as maintaining the stability of co2 price and electricity price to reduce the required subsidy

signaling sustainability leadership empirical evidence of the value of djsi membership we explore the relationship between corporate sustainability reputation and firm value by asking whether signaling sustainability leadership through membership on a recognized sustainability index is value generating increasingly stakeholders are demanding that firms demonstrate their commitment to sustainability one signal that companies can send to stakeholders to indicate that they are sustainability leaders is membership on a recognized best in class sustainability index this article explores both the short term and the intermediary impact on north american firms of being included or removed from the dow jones sustainability world index djsi our results provide evidence that being added to the djsi results in a sustained increase in a firm s share price suggesting that the benefits of being included on the djsi outweigh the costs associated with applying this article also notes a temporary decrease in the value of firms for the first 10 days after their removal from the djsi however this effect is eliminated within the next ten trading days

cash crop choice and income dynamics in rural areas evidence for post crisis indonesia in this article we investigate the factors affecting levels and growth of incomes in rural indonesia following the crisis of 1997 1998 in particular we investigate the relative roles of nonfarm incomes and productivity improvements achieved via changes in crops versus improvements on the same crops on income dynamics framing the article in the context of an optimal labor allocation model relying on unique household panel data from central sulawesi and using advanced panel econometric methods we find that local innovations related to the adoption and intensification of new cash crop varieties more specifically the shift from coffee to cocoa production can explain a substantial part of the observed post crisis developments causal estimates of the effect of growing cocoa suggest that households were on average able to achieve about 14 higher income levels during the post crisis period compared to the planting of other crops most notably coffee also our results demonstrate the importance of engagement in nonfarm activities for household income growth comparative analyses using a nationally representative survey suggest that similar processes are at play in other parts of indonesia

singularity and autoregressive disturbances in linear logit models the implications of including autoregressive disturbances in linear logit models of demand systems are explored it is argued that the normality assumption of the error terms is more appropriate in the linear logit model than in a share equation model with additive disturbances commonly found in the literature autoregressive disturbances and their implications for model estimation are discussed in that context both theoretical arguments and empirical evidence are presented in favor of the logit specification given the presence of serial correlation

new evidence on stock price effects associated with changes in the s p 500 index since october 1989 standard and poor s has when possible announced changes in the composition of the s p 500 index one week in advance because index funds hold s p 500 stocks to minimize tracking error index composition changes since this date provide an opportunity to examine the market reaction to an anticipated change in the demand for a stock using post october 1989 data the authors document significantly positive negative postannouncement abnormal returns that are only partially reversed following additions deletions these results indicate the existence of temporary price pressing and downward sloping long run demand curves for stocks and represent a violation of market efficiency copyright 1997 by university of chicago press

the rural non farm sector issues and evidence from developing countries abstract the rural non farm sector has traditionally been viewed as a low productivity sector which produces low quality goods it is often expected to wither away as a country develops recent years have seen a shift away from this position towards recognition that the rural non farm sector can and often does contribute to economic growth rural employment poverty reduction and a more spatially balanced population distribution this paper reviews the literature on the conceptual and empirical underpinnings of this more recent perspective focussing on the experience in developing countries the paper documents the size and heterogeneity of the sector pointing to evidence that in many countries the sector is expanding rather than declining the issues associated with measuring the sector s economic contribution are discussed followed by empirical assessments for several countries and regions the distributional impact of non farm earnings is examined and it is found that a pro poor impact while by no means inevitable can be considerable the sector s trajectory over time in different settings is reviewed and the scope for and experience of various policy interventions is discussed

the cost of solar centric renewable portfolio standards and reducing coal power generation using arizona as a case study abstract this paper develops an econometric forecasting system of energy demand coupled with engineering economic models of energy supply the framework is used to quantify the impact of a state level renewable portfolio standard rps achieved predominately with solar generation we perform the analysis using arizona s rps as a case study over the period 2012 2035 we find if arizona implements its rps when supplying future electricity demand there will be an increase in electricity rates relative to a business as usual scenario of reliance on gas fired generation extending the current regime of tax credits greatly reduces this increase at the taxpayers expense we find that by 2025 arizona s rps will implicitly abate carbon dioxide emissions at a cost between 58 and 82 per metric ton and by 2035 abatement costs are between 22 and 69 per metric ton depending on the future evolution of nature gas prices the rps always leads to a negative impact on social welfare under low gas prices but after 2029 the welfare impact is positive under high gas prices in contrast phasing out arizona s existing coal fired generation always has positive welfare impacts

global standards and ethical stock indexes the case of the dow jones sustainability stoxx index the increased scrutiny of investors regarding the non financial aspects of corporate performance has placed portfolio managers in the position of having to weigh the benefits of holding the market against the cost of having positions in companies that are subsequently found to have questionable business practices the availability of stock indexes based on sustainability screening makes increasingly viable for institutional investors the transition to a portfolio based on a socially responsible investment sri benchmark at relatively low cost the increasing share of socially responsible investments may play a role in providing incentives towards a continuous upgrading of sustainability standards to the extent that their performance is not systematically inferior to that of the other funds this article examines whether these incentives have been so far detectable with particular reference to the dow jones sustainability stoxx index djssi that focuses on the european corporations with the highest csr scores among those included in the dow jones stoxx 600 index the aim of the article is twofold first we analyse the performance of the djssi over the period 2001 2006 compared to that of the surrogate complementary index sci a new benchmark that includes only the components of the dj stoxx 600 that do not belong to the ethical index to evaluate more correctly the size of possible divergent performances second we perform an event study on the same data set to analyse whether the stock market evaluation reacts to the inclusion deletion in the djssi in both cases the results suggest that the evaluation of the csr performance of a firm is a significant criterion for asset allocation activities

interfuel substitution in the united states in this paper we use the locally flexible translog functional form to investigate the demand for energy and interfuel substitution in the united states and to provide a comparison of our results with most of the existing empirical energy demand literature motivated by the widespread practice of ignoring theoretical regularity we follow barnett s 2002 suggestions and estimate the model subject to theoretical regularity using methods developed by diewert and wales 1987 and ryan and wales 2000 in an attempt to produce inference consistent with neoclassical microeconomic theory moreover we use the most recent data published by the u s energy information administration eia and in addition to investigating interfuel substitution possibilities in total u s energy demand we follow serletis et al 2009 and also examine interfuel substitution possibilities in energy demand by sector moreover we test for weak separability with the objective of discovering the structure of the functional form in total energy demand as well as energy demand by sector

weaving together the normative and regulative roles of government how the norwegian sovereign wealth fund s responsible conduct is shaping firms cross border investments based on institutional theory i extend research on the regulative role of national government in society and suggest that government exerts important influences on firms actions through the diffusion of norms i suggest that the norwegian government by instituting an ethical council that publicly censors and certifies the cross border investments of the norwegian sovereign wealth fund government pension fund global contributes to the professionalization of responsible investment principles and thus plays a normative role in shaping firms investments employing a quasi natural experiment i find that focal norwegian firms are more likely to make responsible cross border investments following the formation of the council on ethics in 2004 and its associated censorship announcements further i find that the normative pressure for responsible investments is mediated by firms imitation or overlap with the norwegian sovereign wealth fund s investments however the mediated effect of normative pressure on responsible investments becomes weaker for government owned firms these findings highlight the importance of normative mechanisms through which government can influence firms behavior especially in contexts where regulatory authority may not hold moreover these findings reveal the interplay among the normative mimetic and regulative pressures and the heterogeneity in the extent to which firms within the same country demonstrate institutional isomorphism

estimating the value of wind energy using electricity locational marginal price abstract there is an increasing interest in adding renewables such as wind to electricity generation portfolios in larger amounts as one response to concern about atmospheric carbon emissions from our energy system and the resulting climate change most policies with the aim of promoting renewables e g rps fit do not explicitly address siting issues which for wind energy are currently approached as the intersection of wind resource land control and transmission factors this work proposes the use of locational marginal price lmp the location and time specific cost of electricity on the wholesale market to signal locations where generation can address electricity system insufficiency after an examination of the spatial and temporal behavior of lmp in michigan over the first two years of wholesale market operation this work combines lmp with wind speed data to generate a value metric high value sites in michigan tend to be sites with higher wind speeds with the bulk of value accruing in the fall and winter seasons

introduction to the special issue on the role of nonfarm income in poverty reduction evidence from asia and east africa in this special issue we present seven studies that collectively attempt to investigate the role of non farm income in long term and short term poverty reduction in asia and africa the first four studies out of the seven use long term panel data over two decades in the philippines thailand bangladesh and india these studies show drastic increases in non farm income shares and corresponding declines in poverty levels over time especially in the philippines and thailand education levels of household members and returns to education also increased significantly in these countries the remaining three studies use cross sectional and short term panel data from ethiopia kenya and uganda these african studies show high proportions of poor households and low shares of non farm income that are somewhat comparable to the situation in the 1980s described in the asian studies without the green revolution that provided stable farm income and potential financial resources to invest in children education in asia it is not clear if african farm households can follow the asian examples

a critical review of sustainable business indices and their impact most studies into the performance of socially responsible investment vehicles have focused on the performance of sustainable or socially responsible mutual funds this research has been complemented recently by a number of studies that have examined the performance of sustainable investment indices in both cases the majority of studies have concluded that the returns of socially responsible investment vehicles have either underperformed or failed to outperform comparable market indices although the impact of sustainable indices to date has been limited the recent launch of sustainable indices by dow jones and ftse suggests that more attention is being paid to the subject by financial markets investors and companies this development raises a number of important issues which are reviewed in this article a the performance of indices compared with their benchmark indices b the methodologies employed in compiling the indices and c the impact of the indices on companies and the investment community the article concludes with a number of suggestions for areas that merit future research

prices technology development and the rebound effect abstract energy efficiency is the critical parameter for policies that aim at reducing energy consumption while maintaining or even boosting economic growth the two main options to influence energy efficiency are changes in relative prices i e raising the price of energy through economic instruments or to introduce new technologies which increase the productivity of each unit of energy this paper is based on the notion that in an equilibrium economy the marginal economic productivity is identical for all factors i e energy labour knowledge and capital from this premise two main conclusions can be drawn first any change in price or technology will have an impact on the whole economy by creating feedbacks through the substitution of factors of production and goods as well as increased wealth second the two policy approaches changing relative prices and technology development are not opposite to each other they are the two faces of the same reality and should be developed and promoted simultaneously and consistently

cost effectiveness of renewable electricity policies we analyze policies to promote renewable sources of electricity a portfolio standard rps raises electricity prices and primarily reduces gas fired generation a knee of the cost curve exists between 15 and 20 goals for 2020 in our central case and higher natural gas prices lower the cost of greater reliance on renewables a renewable energy production tax credit lowers electricity price at the expense of taxpayers which limits its effectiveness in reducing carbon emissions and it is less cost effective at increasing renewables than a portfolio standard neither policy is as cost effective as a cap and trade policy for achieving carbon emission reductions

price and volume effects associated with changes in the s p 500 list new evidence for the existence of price pressures attempts to identify price pressures caused by large transactions may be inconclusive if the transactions convey new information to the market this problem is addressed in an examination of prices and volume surrounding changes in the composition of the s p 500 since these changes cause some investors to adjust their holdings of the affected securities and since it is unlikely that the changes convey information about the future prospects of these securities they provide an excellent opportunity to study price pressures the results are consistent with the price pressure hypothesis immediately after an addition is announced prices increase by more than 3 percent this increase is nearly fully reversed after 2 weeks the efficient market hypothesis emh predicts that security prices reflect all publicly available information therefore one corollary of the emh is that you can sell or buy large blocks of stock at close to the market price as long as you can convince other investors that you have no private information 1 this statement assumes that securities are near perfect substitutes for each other if so the excess demand for a single security will be very elastic and the sale or purchase of a large number of shares will have no impact on price in contrast to the emh scholes 8 kraus and stoll 5 hess and frost 4 and others propose two hypotheses which predict that a large stock sale purchase will cause the price to decrease increase even if no new information is associated with the transaction the imperfect substitutes hypothesis ish also known as the distribution effect hypothesis assumes that securities are not close substitutes for each other and hence that long term demand is less than perfectly elastic under this hypothesis equilibrium prices change when demand curves shift to eliminate excess demand price reversals are not expected because the new price reflects a new equilibrium distribution of security holders the price pressure hypothesis pph assumes that investors who accommodate demand shifts must be compensated for the transaction costs and portfolio risks that they bear when they agree to immediately buy or sell securities which they otherwise would not trade these passive suppliers of liquidity are attracted by immediate price drops rises associated with large sales purchases they are compensated for their liquidity service when prices rise drop to their fullinformation levels the pph like the emh assumes that long run demand is

market reactions to corporate environmental performance related events a meta analytic consolidation of the empirical evidence research on the relationship between corporate environmental performance cep and corporate financial performance cfp has consistently grown and is gaining widespread attention given the vast body of cep cfp studies recently scholars have begun to take stock of the cumulative results however no study so far has meta analyzed the findings yielded by event studies assessing the stock market reactions to corporate environmental performance related events cep related events this paper sets out to close this gap by synthesizing previous empirical results regarding the stock market impact of positive and negative cep related events results indicate a positive relationship across studies in terms of positive market reactions to positive events and negative reactions to negative events furthermore the findings show that the market reactions are stronger for negative events than for positive events i e asymmetry in the stock market reaction finally this study examines whether methodological artifacts i e differences in the study designs may explain the differences in the findings of the analyzed event studies

the price response to s p 500 index additions and deletions evidence of asymmetry and a new explanation we study the price effects of changes to the s p 500 index and document an asymmetric price response there is a permanent increase in the price of added firms but no permanent decline for deleted firms these results are at odds with extant explanations of the effects of index changes that imply a symmetric price response to additions and deletions a possible explanation for asymmetric price effects arises from the changes in investor awareness results from our empirical tests support the thesis that changes in investor awareness contribute to the asymmetric price effects of s p 500 index additions and deletions the long held assumption that stocks have perfect substitutes and the perfect elasticity of demand that follows from it is central to modern finance theory if securities have almost perfectly elastic demand then any supply or demand shocks that are devoid of information should have no effect on the prevailing price early empirical research on whether price changes occur in the absence of new information focused on block trades equity issues and stock splits but was unable to exclude information effects around these events since there is no obvious reason to believe ex ante that index changes contain new information they constitute a natural framework for testing whether stocks have almost perfectly elastic or horizontal demand curves a stock s excess return around such changes could be consistent with a downward sloping demand curve with the advent of indexed mutual funds in 1976 and the public announcement of s p index changes in the same year there is much evidence that such announcements are accompanied by an increase in price for firms added to the index if stocks have a short term downward sloping demand curve the price should be momentarily affected by a demand shock due to indexing but that effect

event studies in management research theoretical and empirical issues we examined the use of event studies in management research and found that there was inadequate attention paid to theoretical and research design issues this lack of attention may lead to false in

dynamic translog and linear logit models a factor demand analysis of interfuel substitution in us industrial energy demand abstract we compare and contrast two popular dynamic flexible functional forms for cost functions the translog and the logit j bus econ stat 8 1990 347 353 using data on us industrial energy demand from 1960 to 1992 which has been analysed by previous studies energy econ 11 1989 89 94 appl econ 21 1989 931 945 j bus econ stat 13 1995 459 465 we show the crucial role played by different dynamic formulations of the translog in this analysis of factor demands with respect to rates of dynamic adjustment and substitution possibilities we conclude that the poor performance of the dynamic translog relative to the dynamic logit cannot be explained solely by dynamic model mis specification or the inclusion of price unresponsive non energy fuel use data our most robust empirical result is that coal and oil are substitutes

nonfarm employment agricultural shocks and poverty dynamics evidence from rural uganda this article examines the role of off farm employment in poverty reduction over a short period of time by using panel data from 894 rural ugandan households in 2003 and 2005 taking advantage of the unique off farm labor supply and income data we analyzed how households respond to negative agricultural shocks especially through off farm labor supply and income to mitigate crop income loss our analysis indicates that the flexibility of labor time allocation varies across off farm jobs and that only low skilled and low wage jobs tend to be used to mitigate negative shocks especially among the asset poor

how does the market value corporate sustainability performance this study provides empirical evidence on how corporate sustainability performance csp as proxied by membership of the dow jones sustainability index is reflected in the market value of equity using a theoretical framework combining institutional perspectives stakeholder theory and resource based perspectives we develop a set of hypotheses that relate the market value of equity to csp for a sample of north american firms our preliminary results show that csp has significant explanatory power for stock prices over the traditional summary accounting measures such as earnings and book value of equity however further analyses suggest that we should not focus on corporate sustainability itself our findings suggest that what investors really do is to penalize large profitable firms with low level of csp firms with incentives to develop a high level of csp not engaging on such strategy are thus penalized by the market

non farm activity household expenditure and poverty reduction in rural vietnam 2002 2008 summary diversifying into non farm activities has been suggested as an effective way out of poverty for rural households in developing countries using the vietnamese household living standards surveys of 2002 2004 2006 and 2008 we test this claim and investigate the effect of non farm sector involvement on poverty and expenditure growth our endogeneity corrected estimates show that an additional household member involved with non farm activity reduces the probability of poverty by 7 12 and increases the household expenditure by 14 over a two year period our findings also indicate that non farm involvement reduces the hours worked on farm but not the household agricultural income

state renewable energy electricity policies an empirical evaluation of effectiveness over the past decade state governments have emerged as us energy policy leaders across the country states are adopting policy instruments aimed at carbon mitigation and renewable energy deployment one of the most prevalent and innovative policy instruments is a renewable portfolio standard rps which seeks to increase the share of renewable energy electrification in the electricity market this analysis evaluates the effectiveness of state energy programs with an empirical investigation of the linkage between state rps policy implementation and the percentage of renewable energy electricity generation across states we use a variant of a standard fixed effects model referred to as a fixed effects vector decomposition with state level data from 1998 to 2006 results indicate that rps implementation is not a significant predictor of the percentage of renewable energy generation out of the total generation mix yet for each additional year that a state has an rps policy they are found to increase the total amount of renewable energy generation these findings reveal a potentially significant shortcoming of rps policies political institutions natural resource endowments deregulation gross state product per capita electricity use per person electricity price and the presence of regional rps policies are also found to be significantly related to renewable energy deployment

csr transparency and the role of intermediate organisations transparency is a crucial condition to implement a csr policy based on the reputation mechanism the central question of this contribution is how a transparency policy ought to be organised in order to enhance the csr behaviour of companies governments endorsing csr as a new means of governance have different strategies to foster csr transparency in this paper we discuss the advantages and disadvantages of two conventional policy strategies the facilitation policy and the command and control strategy using three criteria efficiency freedom and virtue we conclude that both strategies are defective most attention is paid to the facilitation strategy since governments nowadays mainly use this in evaluating this strategy we analyse the dutch case as an alternative we introduce a third government policy the development of a self regulating sub system by construing an analogy with the historical development of corporate financial disclosure we point out that the vital step in the creation of a self regulating subsys tem is the creation of strong informational intermediate organisations

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
