a simple estimator for simultaneous models with censored endogenous reggressors this paper presents a simple two step estimator for models with censored endogenous regressors and sample selection bias the approach unifies the literature on censored endogenous regressors and sample selection bias and provides extensions the procedure employs generalized residuals to adjust for the inconsistency caused by the endogeneity of the censored regressors the paper also provides two new tests of weak exogeneity an empirical example examining the trade off between fringe benefits and wages indicates that the estimation procedure works well a monte carlo experiment suggests that the proposed tests have good power properties copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

corporate environmental responsiveness in india lessons from a developing country abstract we examine corporate environmental responsiveness in business organizations in india based on theoretically informed case analysis we operationalize corporate environmental responsiveness as a two order construct we find that level one the lower level responsiveness is driven by pressures arising out of powerful supply chain customers and institutional pressures resulting from internationalization the drivers for organizations at level two the higher level responsiveness are associated with organizational identities and cultures rooted in a long history of social responsiveness

old problems in the new solutions politically motivated allocation of program benefits and the new fertilizer subsidies summary fertilizer subsidies have been reinstituted in many african countries with innovations seeking to avoid the downsides of past programs the new subsidy paradigm however does not address how to curtail political manipulation which exacerbated inefficiencies of previous programs this paper analyzes whether politics affected voucher allocations in ghana s 2008 fertilizer subsidy program we find that more vouchers were targeted to districts that the ruling party had lost in the previous presidential elections and more so in districts that had been lost by a higher percentage margin this evidence shows that a significant threat to the efficiency of fertilizer subsidies remains

a trait based model of the potential demand for a genetically engineered food crop in a developing economy we predict the potential demand of smallholder farmers for genetically transformed varieties of a food crop the cooking banana of the east african highlands farmer demand for planting material is derived in an agricultural household model that accounts for variety traits and missing markets the demand for candidate host varieties is predicted using a zero inflated poisson zip regression system the fitted model is used to illustrate the sensitivity of farmer demand for improved planting material to a investments in research and development represented by the effectiveness of gene insertion and expression and b other public investments in education extension and market infrastructure that support diffusion by comparing the characteristics of agricultural households we demonstrate that the choice of host variety can have social consequences favoring one rural population compared with another clients for transgenic banana planting material are likely to be poorer subsistence oriented farmers in areas greatly affected by biotic constraints a model of this type might be useful in assessing the investments needed to support the systematic dissemination of improved planting material the approach can be generalized to other crop biotechnologies for smallholder farming systems particularly in developing economies

dis incentivizing sustainable intensification the case of zambia s maize fertilizer subsidy program abstract poor and declining soil fertility is a major constraint to increased cereal yields in sub saharan africa while input subsidy programs isps for inorganic fertilizer are a popular and expensive tool used by african governments to increase smallholder farmers cereal yields far fewer resources are devoted to promoting other soil fertility management sfm practices that can improve soil health increase cereal yield response to inorganic fertilizer and support sustainable agricultural intensification moreover little is known about how isps affect farmers use of such sfm practices we examine whether and to what extent household participation in zambia s maize fertilizer subsidy program affects the household s use of fallowing intercropping crop rotation and animal manure using nationally representative panel survey data from zambian smallholder farm households we find that zambia s maize fertilizer subsidy program reduces the probability and extent of fallowing and intercropping of maize with other crops in addition we find some evidence that the program induces an increase in continuous maize cultivation on the same plot over time however the weight of the evidence suggests no statistically significant isp effects on the use of animal manure the analysis uses the mundlak chamberlain device to control for time invariant unobserved heterogeneity and addresses concerns related to the endogeneity of selection into the subsidy program with an instrumental variables control function approach overall our results suggest that zambia s maize fertilizer subsidy program may have dis incentivized sustainable intensification rather than promoted it

low carbon growth for indian iron and steel sector exploring the role of voluntary environmental compliance abstract india s move towards low carbon growth will be successful only when the industries assume responsibilities of climate change previous studies argue that voluntary compliance by firms being business led initiative is appropriate for developing nations however provides little empirical evidence the present study investigates the role of voluntary compliance in improving firms environmental performance in indian iron and steel sector using sample of 76 firms over years 2006 07 to 2011 12 environmental performance is measured by co2 emissions in absence of emission data at firm level we quantify co2 emissions from energy consumption using intergovernmental panel on climate change ipcc reference approach voluntary compliance is indicated by presence of voluntary environmental management standards iso 14001 the study finds that 33 of sample firms comply with iso 14001 further the empirical results based on panel data econometric suggests that there is a significant positive relationship between voluntary compliance and improvement in environmental performance even after addressing simultaneity issues and including other firm characteristics thus voluntary compliance may be used as supplementary policy tool to achieve low carbon growth in industries additionally there is a need to disseminate information about iso 14001 by government as well as firms to create awareness

creating integrated business and environmental value within the context of china s circular economy and ecological modernization abstract this paper investigates the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between economic growth and environmental stewardship in the context of china s emerging circular economy policy paradigm and based on ecological modernization theoretic approaches based on three company case studies in the information technology and electronic industries in china we identify and demonstrate how a blended business and environmental value can be created from adopting a sustainable supply chain management approach the adoption of a sustainable supply chain management approach is rapidly becoming a key business challenge and opportunity in china and other large emerging economies around the world where our greatest environmental management challenges currently reside and will continue to exist for many years to come the value creation framework proposed in research focuses on evaluating three case study companies who appear in various stages of an electronic industry supply chain value creation within a supply chain can provide the impetus for organizations to adopt circular economy sustainable supply chain practices for competitive reasons in addition we describe how a value proposition can be evaluated at two levels of analysis a more specific micro level and a more general meso level of analysis the four major business value dimensions include cost reduction revenue generation resiliency and legitimacy and image the initial findings are that a variety of opportunities exist for electronic firms in emerging and developing countries while results from this study provide an important scholarly foundation to develop and refine sustainable supply chain management practices in emerging and developing economies

corporate strategy and international environmental policy this paper analyzes the interactions between international environmental policy and multinational corporate strategy the main contribution is building a new conceptual framework to analyze the type of corporate strategy developed in the presence of both national an international environmental regulations this framework distinguishes between firm level compliance with environmental obligations and the development of resource based green capabilities it also classifies major environmental regulations and incorporates a discussion of public policy

sustainable competitive advantage combining institutional and resource based views this article suggests that the context and process of resource selection have an important influence on firm heterogeneity and sustainable competitive advantage it is argued that a firm s sustainable advantage depends on its ability to manage the institutional context of its resource decisions a firm s institutional context includes its internal culture as well as broader influences from the state society and interfirm relations that define socially acceptable economic behavior a process model of firm heterogeneity is proposed that combines the insights of a resource based view with the institutional perspective from organization theory normative rationality institutional isolating mechanisms and institutional sources of firm homogeneity are proposed as determinants of rent potential that complement and extend resource based explanations of firm variation and sustainable competitive advantage the article suggests that both resource capital and institutional capital are indispensable to sustainable competitive advantage 1997 john wiley sons ltd

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

can crop purchase programs reduce poverty and improve welfare in rural communities evidence from the food reserve agency in zambia the last decade has seen a resurgence of parastatal crop marketing institutions in sub saharan africa many of which cite improving food security and incomes as key goals however there is limited empirical evidence on the welfare effects of these programs this article considers one such program the zambian food reserve agency fra which purchases maize from smallholder farmers at a pan territorial price that typically exceeds maize market prices in surplus production areas using both fixed effects and an instrumental variables approach combined with correlated random effects we estimate the effects of the fra s maize marketing activities on smallholder farm household welfare results suggest that fra activities have positive direct welfare effects on the small minority of smallholder households that are able to sell to it however the results also suggest negative indirect fra effects as higher levels of fra activity in a district are associated with higher levels of poverty

taking stock of the local impacts of community owned renewable energy a review and research agenda abstract a growing literature suggests that community owned renewable energy cre projects have the potential to deliver a range of environmental and local socio economic benefits there is relatively little empirical evidence to substantiate this with few systematic efforts to assess social and environmental impacts or to understand the context in which given impacts arise in this paper we review and conceptualise the local impacts commonly cited in the literature and dissect the empirical evidence currently available to support their occurrence having assessed the quality of evidence and pinpointed knowledge gaps we draw on methodological literature to identify approaches necessary to improve our understanding of the local impacts of cre and explore their patterns of occurrence we find a lack of robust survey and statistical evidence across all the seven impact categories identified of the impacts identified empowerment and access to affordable energy are found to be the least studied in addition several impacts are associated only with specific types of community energy projects we argue that the paucity of consistent evidence for direct impacts associated with the development processes and direct outcomes of projects suggests that the most substantial local impacts result from medium to long term indirect project outcomes and the investment of project revenues in the local community as such collective funding pools and negotiation processes around their distribution towards private versus public goods play a crucial role in determining transformative local impacts of cre

ex post analysis of economic impacts from wind power development in u s counties wind power development has surged in recent years in the united states policymakers and economic development practitioners to date have typically relied upon project level case studies or modeled input output estimates to assess the economic development impacts from wind power often focusing on potential local state wide or national employment or earnings impacts building on this literature we conduct an ex post econometric analysis of the county level economic development impacts of wind power installations from 2000 through 2008 in a large wind rich region in the country taking into account factors influencing wind turbine location we find an aggregate increase in county level personal income and employment of approximately 11 000 and 0 5 jobs per megawatt of wind power capacity installed over the sample period of 2000 to 2008 these estimates appear broadly consistent with modeled input output results and translate to a median increase in total county personal income and employment of 0 2 and 0 4 for counties with installed wind power over the same period

impacts of subsidized hybrid seed on indicators of economic well being among smallholder maize growers in zambia we test the hypotheses that subsidies on hybrid seed change maize production total household income the severity of poverty and relative deprivation among smallholder maize growers in zambia the analysis contributes to the literature by measuring the quantitative effects of seed as compared to fertilizer subsidies on indicators of household well being rather than input demand we apply a combination of econometric approaches to a nationally representative balanced panel of smallholder maize growing households and invoke the chain rule to generate quantitative estimates of impacts per kilogram of subsidized seed our findings demonstrate that in the initial years of the program subsidized seed enhanced the well being of smallholder maize growers according to each indicator but by small magnitudes simple calculations suggest high private and social benefit cost ratios when benefits are measured in terms of household income although magnitudes are sensitive to seed price and administrative costs

markets and pro poor agricultural growth insights from livelihood and informal rural economy models in malawi this article presents the development of a set of programming models describing the major features of different rural livelihoods and of the informal rural economy they together make up in malawi the models allow for differentiated responses by different household types to change and for the partial equilibrium effects of consequent supply demand and price adjustments in labor and grain markets the models provide insights into the relations between own farm and nonown farm activities in different households livelihoods and in the informal rural economy as a whole and are used to investigate possible impacts of increasing cash crop prices and of a more open rural economy impacts of these changes on the poor are found to be critically dependent upon supply and demand elasticities in labor and grain markets but the poor could potentially suffer significant losses from increased openness of the local economy leading to increased expenditure by less poor households on imported goods and services

firm self regulation through international certifiable standards determinants of symbolic versus substantive implementation international certifiable management standards that have been advocated as a governance mechanism for firm self regulation of corporate social responsibility issues are effective only if certified firms comply with the requirements of the standards our empirical analysis shows that iso certified firms in china strategically select their level of compliance depending on customer preferences customer monitoring and expected sanctions by customers our findings have implications for the effectiveness of a global system of self regulation based on certifiable standards research on certifiable standards and for practicing managers who require suppliers to obtain standard certifications

determinants of proactive environmental management practices in indian firms an empirical study abstract the present study aims to empirically determine the primary factors that have a major influence on adoption of environmental management practices in indian firms for this purpose a theoretical framework has been proposed based on previous studies and a pilot survey that provides broad and specific variables that might have an impact of these practices this impact has been investigated by conducting factor analysis and stepwise regression analysis in order to collect the primary data a questionnaire has been designed for which 104 valid responses 8 5 response rate have been obtained the study reveals that internal holder ship and employees and market commercial buyers and suppliers of goods and services pressures are the significant drivers who govern the adoption of proactive environmental management practices however the external pressures from regulatory and societal stakeholders were not found to be important in the indian context the analysis further showed that firm s characteristic also play a significant role in defining the positive behavior of firms as large firms are more proactively engaged in environmental management initiatives moreover firms in the manufacturing chemical and agriculture sector are likely to have more comprehensive environmental management practices compared to the service sector

zambia s input subsidy programs over the last decade subsidies for fertilizer and hybrid maize seed have re emerged as a cornerstone of the government of the republic of zambia s grz s agricultural development and poverty reduction strategies this article reviews the farmer input support programme fisp and other grz input subsidy programs since structural adjustment it then synthesizes existing and presents new empirical evidence on the programs targeting outcomes and effects results suggest that although 73 of smallholder households cultivate less than 2 hectares of land and that these households constitute 78 of the smallholder farms below the us 1 25 capita day poverty line the majority 55 of fisp fertilizer goes to households that cultivate larger areas other factors constant wealthier households receive more subsidized inputs subsidized fertilizer promotes maize intensification and extensification at the expense of fallow land but an additional kg of subsidized fertilizer only raises maize output by 1 88 kg on average as a result of low maize fertilizer response rates poor targeting crowding out and diversion of fertilizer intended for the program financial benefit cost ratios for fisp fertilizer are well below one the article concludes with recommended reforms to fisp including that it be downsized and the savings invested in known drivers of pro poor agricultural growth

an economic assessment of windfarm power generation in scotland including externalities abstract this paper uses cost benefit analysis to assess the economic feasibility of a large scale windfarm project taking into account positive and negative externalities of generation the issue of non use value i e a welfare change among those who will never visit the area and see the windfarm is addressed with reference to the study by bergmann et al 2006 valuing the attributes of renewable energy investments energy policy 34 1004 1014 which determined a social cost of 19 40 per household for the non use disamenity associated with a large scale windfarm in scotland this paper demonstrates the extent to which this estimate affects the economic feasibility of the project we find that for all but one of the 16 scenarios considered the project returns a positive net present value despite the inclusion of this non use value thus suggesting that in these cases the windfarm delivers a net welfare gain to society

determinants of pollution abatement in developing countries evidence from south and southeast asia abstract developing countries pa ticularly those in asia are fast adopting industrial pollution control standards similar to those in developed countries formal regulation has been greatly hampered however by the absence of clear and legally binding regulations limited institutional capacity lack of appropriate equipment and trained personnel and inadequate information on emissions one would predict highly pollution intensive production under such conditions our research however has uncovered strongly contradictory evidence despite weak or nonexistent formal regulation there are many clean plants in the developing countries of south and southeast asia of course there are also many plants which are among the world s most serious polluters what explains such extreme interplant variation this paper reviews evidence drawn from three empirical studies of plant level abatement practices conducted 1992 1994 the analyses test the importance of plant characteristics economic considerations and external pressure in determining environmental performance the results consistently show that pollution intensity is negatively associated with scale productive efficiency and the use of new process technology it is strongly and positively associated with public ownership but foreign ownership has no significant effect once other plant characteristics are taken into account among external sources of pressure community action or informal regulation emerges as a clear source of interplant differences in all three studies the results suggest that local income and education are powerful predictors of the effectiveness of informal regulation they also show that existing formal regulation has measurably beneficial effects even when it is quite weakly developed

historic paths and future expectations the macroeconomic impacts of the offshore wind technologies in the uk abstract offshore wind power osw plays a key role within the uk strategy for a transition towards a low carbon economy offering vast potential for establishing a high tech manufacturing industry previous experiences in the onshore sector owp suggest the uk might fail in fully capturing these macroeconomic benefits in this work we investigate the history of uk renewable policies comparing its national strategy to those of other major osw export countries through the use of a numerical general equilibrium model we quantify the macroeconomic impacts under three scenarios a baseline which relies on previous estimates and foresee limited local content a contamination scenario where the uk content reaches the same levels of owp and a non myopic scenario where investors expect governmental support to decrease or disappear replicating a common path of past renewable policies we identify the uk as a fdi oriented country our results suggest that increasing the share of locally sourced capital goods in osp to owp level could generate larger income and employment effects in the uk economy we find that under forward looking investors the economic benefits are significantly lower than the case of myopic agents our results show an inherent conflict with stated purposes of uk policy for osw

disrupting demand for commercial seed input subsidies in malawi and zambia summary this study uses nationally representative household level panel data from malawi and zambia to identify the determinants of subsidized maize seed and fertilizer receipt and to estimate how input subsidies affect households commercial purchases of improved maize seed varieties in both countries we find that households in areas where the ruling party won the last presidential election acquire significantly more subsidized inputs than other households results also indicate that each additional kilogram of subsidized maize seed acquired by a household reduces its commercial improved maize seed purchases by 0 58 kg in malawi and by 0 49 kg in zambia on average

the effect of household wealth on the adoption of improved maize varieties in zambia abstract production and price risks that could render input use unprofitable sometimes prevent rural households from benefiting from input technological change the household s ability to cope with such risks and hence benefit from input technological change is often positively related to its wealth or stock of productive assets empirical evidence however suggests a non linear relationship between wealth and adoption of new agricultural technologies so that within a rural community households on the lower wealth continuum behave differently from those on the higher level using farm level data collected from 300 randomly selected households in three districts of zambia in 2004 2005 crop season this paper first stratifies households into poorly and well endowed households based on their access to productive assets and estimates separate double hurdle models for the adoption of improved high yielding maize ihym varieties for each group the results show that factors influencing the adoption and use intensity of ihym varieties differ between the two groups this draws attention to the need for recommending wealth group specific interventions to increase the adoption and use intensity of such varieties and their subsequent impacts on food security and general livelihoods of the households the explicit testing for the possibility that differences in household wealth affect the way in which other variables influence adoption decisions is the paper s unique contribution to the adoption literature

is there a case for community based equity participation in scottish on shore wind energy production gaps in evidence and research needs abstract this paper considers the potential rural development benefits of community ownership or co ownership or equity participation of on shore wind energy developments and argues for further research to assess the case for enhanced policy support for such ownership structures previous authors have argued that if communities are given a stake in renewables enterprises this will support the scottish government s community empowerment agenda increase economic activity in rural scotland and provide substantial benefits to rural communities others have argued that community ownership schemes may decrease community resistance to on shore wind developments and set beneficiary communities on a low carbon development pathway through stimulating energy citizenship however empirical evidence to support all of these claims remains limited focussing on scotland where the growth of on shore wind has been strong in recent years the paper reviews the current policy environment and governance context before reviewing evidence in relation to the various arguments for community ownership or shared equity in the case of on shore wind energy it identifies several areas where further research is urgently required to guide policy makers so as to ensure that both rural development objectives and renewable energy targets are met

the economics of distributed energy generation a literature review the uk electricity system is likely to face dramatic technical and institutional changes in the near future current uk energy policy focuses on the need for a clean affordable and secure energy supply decentralisation of the electricity system is recognised as one means of achieving efficient and renewable energy provision as well as addressing concerns over ageing electricity infrastructure and capacity constraints in this paper we provide a critical literature review of the economics of increased penetration of distributed energy generation we find that there exists a large volume of research considering the financial viability of individual distributed generation technologies and we are necessarily selective in our review of these studies given the wide variety of technologies that the definition of distributed generation encompasses however there are few studies that focus on the pure economics of individual or groups of distributed energy generators and even fewer still based on the economy wide aspects of distributed generation in view of this gap in the literature we provide suggestions for future research which are likely to be necessary in order adequately to inform public policy on distributed generation and its role in the future of uk energy supply

what are the effects of input subsidy programs on maize prices evidence from malawi and zambia an important hypothesized benefit of large scale input subsidy programs in africa is that by raising maize production the subsidies should put downward pressure on retail maize prices to the benefit of urban consumers and the rural poor who tend to be net food buyers to inform debates related to this rationale for input subsidies this study estimates the effects of fertilizer subsidies on retail maize prices in malawi and zambia using market or district level panel data covering the 2000 2001 to 2011 2012 maize marketing years results indicate that roughly doubling the size of malawi s subsidy program reduces maize prices by 1 2 2 5 on average in zambia roughly doubling the scale of the country s subsidy program reduces maize prices by 1 8 2 8 on average the results are robust across countries and model specifications and indicate that the fertilizer subsidy programs in malawi and zambia have had a minimal effect on retail maize prices

greening regional development employment in low carbon and renewable energy activities abstractgreening regional development employment in low carbon and renewable energy activities regional studies the promotion of low carbon and renewable energy lc re activities has become an important element of development policy in many regional economies in practice defining and measuring these activities presents conceptual methodological and operational challenges this paper illustrates these difficulties using three recent estimates of lc re jobs for scotland it proposes that information on the lc re sector should be embedded in a set of input output accounts this would facilitate the planning implementation and monitoring of lc re based regional development policy

does storage technology affect adoption of improved maize varieties in africa insights from malawi s input subsidy program abstract to date there is limited knowledge of how having access to post harvest storage technology affects a smallholder african farmer s decision to adopt higher yielding improved maize varieties this is a key issue because higher yielding varieties are known to be more susceptible to storage pests than lower yielding traditional varieties we address this question using panel data from malawi and incorporating panel estimation techniques to deal with unobserved heterogeneity our results indicate that acquiring chemical storage protectants after the previous harvest is associated with a statistically significant and modest positive impact on the probability of adopting improved maize total area planted to improved maize varieties and share of area planted to improved maize varieties in the next planting season we also find that the storage chemical subsidy is associated with significant crowding out of commercial storage chemical purchases as farmers who acquire subsidized chemicals are more than 50 percentage points less likely to purchase commercial chemicals on average these findings have implications for maize adoption and input subsidy policies and they indicate that researchers extension staff and policy makers should consider post harvest issue when promoting adoption of improved varieties

do input subsidy programs crowd in or crowd out commercial market development modeling fertilizer demand in a two channel marketing system many governments in developing countries distribute fertilizer at subsidized prices in an effort to stimulate small farmers agricultural productivity and food security prior fertilizer demand studies have largely failed to account for the effects of government programs on farmers commercial purchases using a double hurdle model and nationally representative rural household panel data in zambia we distinguish between these sources and measure the contemporaneous crowding in and crowding out effects of government input programs on commercial fertilizer sales where the private sector is relatively active and average wealth is higher areas seemingly more likely to be targeted by government programs results indicate that subsidies have substantially crowded out the private sector in some cases to the point that such programs could actually lower overall fertilizer use on the other hand in poorer areas where the private sector is relatively inactive subsidies help to generate demand and crowd in private sector retailers empirical studies explicitly modeling farmers fertilizer purchase behavior within a dual marketing framework can provide important insights for agricultural policy discussions in developing countries

exploring new ways of assessing the effect of regulation on environmental management abstract studies indicate that while a variety of factors positively influence voluntary environmental management regulatory pressures are among the most important however most research examines samples representing large manufacturers or single industries essentially assuming a level of regulatory constraint using a sample of heterogeneous facilities this study finds that facilities can be classified according to the level of regulatory constraint and that group membership impacts the choice of environmental management strategy when assessed within a utility maximization framework more extensively regulated facilities implement more individual environmental management practices but participate in fewer formal voluntary environmental programs veps compared to other facilities

understanding community benefit payments from renewable energy development abstract it is increasingly common for renewable energy projects to make financial or in kind payments to local communities these arrangements are variously described as benefits payments or compensation schemes similar approaches are now being recommended for other forms of development with potential to engender opposition from local communities e g nuclear power and fracking while such payments are common the level of payment the institutional frameworks involved and the nature of discourse varies greatly existing literature has sought to record rather than explain the diversity of arrangements to a large extent this diversity is rooted in the power dynamic between developer and community three uk case studies are used to highlight the diversity of arrangements meanings and power balances within benefits arrangements finally a typology is developed to illustrate the spectrum of potential arrangements this typology gives insight into why various arrangements emerge in response to their specific contexts

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item

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

cropland allocation effects of agricultural input subsidies in malawi summary we measure the impacts of malawi s farm input subsidy program on the cropland allocation decisions of farmers in kasungu and machinga districts in central and southern malawi using a two step regression strategy to control for endogenous selection into the program we find positive correlations between participation in the program and the amount of land planted with maize and tobacco furthermore results suggest that participating households simplified crop production by allocating less land to other crops e g groundnuts soybeans and dry beans our findings have implications for policies aimed at promoting both food self sufficiency and crop diversification in low income settings 2011 elsevier ltd all rights reserved
