estimating households vulnerability to idiosyncratic and covariate shocks a novel method applied in madagascar households in developing countries are frequently hit by severe idiosyncratic and covariate shocks leading to high consumption volatility a household s currently observed poverty status might therefore not be a good indicator of the household s general vulnerability to poverty in the recent years there has been an emerging literature on the concept and empirical analysis of vulnerability but because of strong data requirements for vulnerability analysis and limited availability of panel and shock data for developing countries static poverty analysis still dominates empirical vulnerability studies in this paper we propose a simple method to empirically assess the impact of idiosyncratic and covariate shocks on households vulnerability which can be applied in a wide context as it relies on more commonly available cross sectional or short panel data we empirically illustrate our approach for madagascar we show that covariate shocks have a relatively higher impact on rural households whereas idiosyncratic shocks have a relatively higher impact on urban households vulnerability

a cost benefit analysis of generating electricity from biomass abstract a key challenge internationally is the design of future electricity systems which will bring about emissions savings and fuel security at least cost peat is used to generate electricity in several eu countries mainly to take advantage of indigenous resources and increase fuel mix diversity the irish government has introduced a target of 30 cofiring of peat and biomass by 2015 this paper assesses the feasibility of achieving this target by calculating the available indigenous biomass resource capable of being cofired the cost of meeting the target the benefits in terms of carbon abatement and finally the present value in economic terms of meeting the target results demonstrate that ireland has only half the necessary resource to meet the 30 target and that the net cost of doing so is greater than the cost of what is currently being paid for peat in all of the scenarios considered thus it is concluded that while it may be technically possible to meet the target by combining national resources with imported biomass this is never the least cost option and as a result the targeted focus of government policy may need to be reconsidered

bioenergy policy and market development in finland and sweden abstract the use of biomass in finland and sweden has steadily increased over the past 25 years up to approximately 20 of the primary energy supply in 2001 in both countries most biomass originates from forests forest biomass is now an integral part of modern energy systems although primarily in industry and in the heating sector for example biomass accounts for 7 9 and 53 of the fuel mix in district heating in finland and sweden respectively the general energy policy of both countries has supported biomass for energy over the entire period although specific policies have changed with time research development and demonstration has been continuously supported and some subsidy schemes have been applied in particular for district heating systems dhs and combined heat and power heavy taxation of competing fossil fuels seems to have been the most effective policy instrument although this has been directed mainly at the heat and transportation fuel markets electricity taxes are imposed on consumption industry is largely exempt and do not discriminate significantly between the sources of electricity starting in 2003 sweden will have a quota based system a renewable portfolio standard which is expected to increase biomass based electricity production both countries possess vast and not fully exploited biomass resources in the form of forests and have a history of rational and large scale forestry strong actors exist both with regard to forest ownership and the industrial processing of forest products the user side in particular represented by dhs can also be characterised by strong and professional management over time structures have developed that facilitate an increased use of biomass for energy for example the forest industry infrastructure and extensive district heating actors within these structures have had the ability to react to policies resulting in a stable growth in biomass use

social accountability 8000 standard certification analysis of worldwide diffusion abstract this study analyzes the worldwide diffusion of the social accountability 8000 standard certification in sixty five countries and sixty six activity sectors from 1999 to 2011 the logistic curve model is used to assess the current situation on both a global scale and a local scale additionally instability and concentration indices are used to analyze whether the diffusion process developed in a homogeneous manner across countries and economic sectors the results i increase the understanding of sa8000 s diffusion ii provide an exploratory descriptive analysis of the current sa8000 diffusion worldwide in both macro and microanalyses compared with other standards and iii identify future trends in sa8000 diffusion concluding that currently sa8000 follows a similar pattern than other standards and in consequence a growing trend is expected in next years these findings suggest some challenges and opportunities the standard must be more flexible to accommodate the differing perspectives of cultures increase the dialogue with stakeholders and include more small companies from developing countries

prices versus quantities comparing economic efficiency of feed in tariff and renewable portfolio standard in promoting renewable electricity generation abstract in order to promote renewable electricity generation several countries have been adopting a feed in tariff fit or a renewable portfolio standard rps of these two renewable energy policies investigating which one has better performance is a subject of debate this study comparatively analyzes the economic efficiency of fit and rps in the south korean renewable energy market fit was implemented from 2002 to 2011 while rps has been in force since 2012 hence a comparative analysis of the two policies is ideal the benefit cost ratio and net present value were measured from two different perspectives the government and energy producers the results showed that rps was more efficient for photovoltaic energy from the government s perspective whereas fit for non photovoltaic energy such as wind power bio energy and fuel cells however from the energy producers perspective fit was more efficient for photovoltaic energy while rps was more efficient for non photovoltaic energy

credit markets in northern nigeria credit as insurance in a rural economy this article addresses the issues of imcomplete markets and imperfect information in the context of credit markets in rural northern nigeria in much recent theoretical literature the problems of moral hazard and adverse selection are assumed to be decisive for the organization of agrarian institutions in contrast it is found that in the four villages surveyed credit transactions take advantage of the free flow of information within rural communities information asymmetries between borrower and lender are unimportant and their institutional consequences the use of collateral and interlinked contracts are absent credit transactions play a direct role in pooling risk between households through the use of contracts in which the repayment owed by the borrower depends on the realization of random production shocks by both the borrower and the lender

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

improving social responsibility in rmg industries through a new governance approach in laws developing countries need to reform legislation to ensure the global supply firms in ready made garment rmg industry is adequately addressing obligations of social responsibility literature typically focuses on strategies for raising responsible standards in global buying firms within the rmg industry but fails to focus on implementing strategies for suppliers in developing countries this article addresses this gap by specifically focusing on the rmg industry in bangladesh the home of the third largest rmg supplier in the world it concentrates on analysing how and to what extent the law can assist in developing social responsibility performance of the rmg manufacturing firms in developing countries it ultimately concludes that a new governance approach in laws can effectively increase the social responsibility practice standards of an industry where global buying firms are profit driven and governmental agencies are either inadequate or corrupt

welfare and competition effects of electricity interconnection between ireland and great britain this study analyzes the effects of additional interconnection on welfare and competition in the irish electricity market i simulate the wholesale electricity markets of the island of ireland and great britain for 2005 i find that in order for the two markets to be integrated in 2005 additional interconnection would have to be large the amount of interconnection decreases for high costs of carbon since this causes the markets to become more similar this suggests that in the absence of strategic behavior of firms most of the gains from trade derive not from differences in size between countries but from technology differences and are strongly influenced by fuel and carbon costs social welfare increases with interconnection although at a decreasing rate as the amount of interconnection increases there are also positive effects on competition in ireland the less competitive of the two markets finally it is unlikely that private investors will pay for the optimal amount of interconnection since their returns are significantly smaller than the total social benefit of interconnection

methodologies and perspectives in research on labour relations in global agricultural production networks a review the integration of global south actors into the global agricultural economy has attracted research on labour effects this is because global south actors are often integrated at the level of produc

risk sharing across communities this paper studies cross community risk sharing there is now a large body of theoretical and empirical work on informal insurance where people mitigate risk by sharing income a consistent empirical finding is that risk sharing is not complete within villages often the observed sets of individuals 2 one reason researchers suspect is that risk sharing does not take place at the village level but between individuals and families 3 we build a theoretical model where risksharing takes place between pairs of agents there are idiosyncratic shocks to individual income and community level shocks we consider how the opportunity for cross community links affects the shape and efficiency of risk sharing arrangements we find that when links across villages form there can be less risk sharing within a village welfare is higher for those directly or indirectly connected across villages but lower for those with no path connecting them to the other village overall welfare can be higher thus empirical findings that insurance within a village is not complete is not necessarily evidence of an inefficient pattern of risk sharing relations rather the finding is consistent with risk sharing patterns that involve cross community relations and such patterns may yield higher aggregate welfare despite incomplete insurance within a village this paper makes two contributions first it demonstrates the importance of a network analysis by examining pairwise incentives to form relations and the resulting pattern we can see new risk sharing outcomes second with this network model we show how informal risk sharing across communities has both aggregate and distributional effects to study network outcomes we posit a simple two stage model first we provide a benchmark model for risk sharing for a given network then working backwards we consider incentives to form risk sharing links 4 to illustrate consider a rural population and ask how people might link

augmenting the world bank s estimates ireland s genuine savings through boom and bust abstract the world bank computes estimates of genuine savings gs a leading indicator of sustainable development for most countries a well established literature has called for methodological enhancement this paper presents augmented estimates of irish gs throughout a period of unprecedented economic expansion and decline 1990 2016 a time series constructed predominantly from national sources includes the most comprehensive coverage of pollutants in the literature surveyed we apply a novel method to aid the property rights designation assessment required for transboundary pollutant accounting in sharp contrast to the world bank s estimates our findings suggest that a modern developed economy can exhibit signs of unsustainability furthermore extended environmental damages drive these results suggesting expanded country specific gs may diverge considerably from the world bank s estimates we find rapid economic development and rapid declines in environmental damages can occur concurrently and on the transition away from an unsustainable path

determinants of income diversification amongst rural households in southern mali abstract household level panel data from a representative sample of rural households in southern mali describing the different sources of household income are used to examine the determinants of income diversification a conditional fixed effects logit model is employed in the analysis to control for household specific effects we find evidence that poorer households have fewer opportunities in non cropping activities such as livestock rearing and non farm work and hence less diversified incomes this appears to reflect their relative lack of capital which makes it difficult for them to diversify away from subsistence agriculture the results also indicate that households in remote areas are less likely to participate in the non cropping sector than their counterparts closer to local markets while households with educated heads are more likely to participate in the non farm sector than those with illiterate heads the significance of entry constraints in explaining portfolio diversification suggests that the role of government in making assets as well as improved infrastructure available to poorer households is still essential in promoting income diversification

migration risk and liquidity constraints in el salvador abstract this article utilizes panel data from el salvador to investigate the use of transnational migration as an ex post risk management strategy i show that adverse agricultural conditions in el salvador increase both migration to the united states and remittances sent back to el salvador i show that in the absence of any agricultural shocks the probability that a household sent members to the united states would have decreased on average by 24 26 i also show that the 2001 earthquakes reduced net migration to the united states a one standard deviation increase in earthquake damage reduced the average probability of northward migration by 37 11 the evidence suggests that the effects of the earthquakes had more to do with households retaining labor at home to cope with the effects of the disaster than with the earthquakes disrupting migration financing

current and future financial competitiveness of electricity and heat from energy crops a case study from ireland abstract it has been demonstrated that miscanthus and willow energy crop cultivation could be economically competitive with current agricultural land uses at a farm gate biomass price ranging from 70 to 130 t 1 dry matter styles d thorne f jones m b in review energy crops in ireland an economic comparison of willow and miscanthus production with conventional farming systems biomass and bioenergy may 2006 this paper uses the same farm gate prices to calculate the economic competitiveness of energy crop electricity and heat production using a net present value npv approach 20 year period 5 discount rate direct and gasified co firing of willow wood with coal would result in electricity generation 30 or 37 more expensive than coal generation at current coal and co 2 allowance prices and a farm gate biomass cost of 100 t 1 break even co 2 allowance prices are 33 and 37 t 1 respectively however co firing of miscanthus with peat is close to economic competitiveness and would require a co 2 allowance price of 16 t 1 to break even against a current price of 12 t 1 npv analyses indicate that wood heat is significantly cheaper than oil gas or electric heat excluding existing wood boiler installation subsidies discounted annual savings range from 143 compared with gas to 722 compared with electric heating at the domestic scale and from 3454 to 11 222 at the commercial scale inclusion of available subsidies improves the comparative economics of domestic wood heat substantially the economic advantage of wood heat is robust to variation in fuel prices discount rates and heat loads the greatest obstacles to energy crop utilisation include i a reluctance to consider long term economics ii possible competition from cheaper sources of biomass iii the need for a spatially coordinated supply and utilisation network

the demand side of social protection lessons from cambodia s labour rights experience summary in fragile states recent efforts to advance the social protection agenda have focused primarily on loosening supply side constraints but the resulting kaleidoscope of donor driven projects has often overlooked the need to create a sense of ownership by beneficiaries in part this is because it is unclear what political and social structures effectively facilitate activism in situations where state society relations are contentious we use cambodia s unusual success creating and sustaining a labor rights regime to illustrate the dynamics behind one type of social regime change that has opened up governance over worker protections in a sustainable and potentially replicable way

the macroeconomic consequences of disasters abstract natural disasters have a statistically observable adverse impact on the macro economy in the short run and costlier events lead to more pronounced slowdowns in production yet interestingly developing countries and smaller economies face much larger output declines following a disaster of similar relative magnitude than do developed countries or bigger economies a close study of the determinants of these adverse macroeconomic output costs reveals several interesting patterns countries with a higher literacy rate better institutions higher per capita income higher degree of openness to trade and higher levels of government spending are better able to withstand the initial disaster shock and prevent further spillovers into the macro economy these all suggest an increased ability to mobilize resources for reconstruction financial conditions also seem to be of importance countries with more foreign exchange reserves and higher levels of domestic credit but with less open capital accounts appear more robust and better able to endure natural disasters with less adverse spillover into domestic production

biomass direct fired power generation system in china an integrated energy ghg emissions and economic evaluation for salix abstract to gain a better understanding of the options of biomass power generation in china this study presented an integrated energy environmental and economic evaluation for salix in china and a typical salix direct fired power generation system sdpgs in inner mongolia was selected for case study a tiered hybrid life cycle assessment lca model was developed to calculate the planting to wire ptw energy consumption greenhouse gas ghg emissions and economic cost and profit of the sdpgs including feedstock cultivation power plant construction and operation and on grid price with without government subsidies the results show that the ptw energy consumption and ghg emissions of salix are 0 8 mj kwh and 114 g co2 eq kwh respectively indicating an energy payback time epbt of 3 2 years the sdpgs is not economically feasible without government subsidies the ptw costs are dominated by feedstock cultivation the energy saving and ghg mitigation benefits are still robust even when the power plant runs at only 60 design capacity for future development of biomass power in china scientific planning is necessary to guarantee a sufficient feedstock supply in addition technology progress mature industrial chains and reasonable price setting policy are required to enable potential energy and environmental advantages of biomass power moving forward

post disaster aid and development of the manufacturing sector lessons from a natural experiment in china abstract we adopt a disaggregate approach to study the link between aid and dutch disease dynamics using a natural experiment in china specifically we examine whether post disaster aid provided to a subsample of chinese counties devastated by an earthquake in 2008 affects the sectoral composition of local economies using different methods we consistently find that counties receiving more aid even nearby counties not directly damaged by the earthquake tend to suffer from a contraction of the manufacturing sector innovative features of the paper include its regional perspective its identification strategy resting on a special provision in chinese policy pairwise aid and its focus on dutch disease effects in the context of post disaster aid

using weather variability to estimate the response of savings to transitory income in thailand this paper measures the extent to which farmers are able to use savings and dissavings to smooth consumption in response to unexpected shocks to income time series information on regional rainfall is used to construct estimates of transitory income due to rainfall shocks the relationship between these measures of transitory income and savings indicates that farm households save a significantly higher fraction of transitory income than nontransitory income jel d91 016 the incomes of farm households in developing countries are notorious for being both low and uncertain policies that increase the incomes of farmers may well be different

risk aversion and land allocation between annual and perennial crops in semisubsistence farming a stochastic optimization approach this article analyzes the effect of production uncertainty on farmland allocation decisions between perennial and annual crops focusing on a representative farmer s attitude toward risk a dynamic stochastic optimization model that considers net planting the difference between new plantings and removals of perennial crops that achieve full production cycle is used the effect of uncertainty on the representative farmer s decisions to increase or decrease perennial crops acreage on the optimal path is examined our results reveal that the response of optimal path of net planting to uncertainty related to perennial crop production is highly affected by the farmer s attitude toward risk a risk averse or a low risk loving farmer tends to reduce land allocation to perennial crops under uncertainty while a high risk loving farmer will do exactly the opposite also due to disutility of farming the farmer tends to reduce land allocation to perennial crops when prices are high enough for him to attain a desired income level expectation one implication of this research is the need for mechanization in sub saharan countries in particular that increases per acreage yield and output in semisubsistence agriculture

economic and social upgrading in global value chains and industrial clusters why governance matters the burgeoning literature on global value chains gvcs has recast our understanding of how industrial clusters are shaped by their ties to the international economy but within this context the role played by corporate social responsibility csr continues to evolve new research in the past decade allows us to better understand how csr is linked to industrial clusters and gvcs with geographic production and trade patterns in many industries becoming concentrated in the global south lead firms in gvcs have been under growing pressure to link economic and social upgrading in more integrated forms of csr this is leading to a confluence of private governance corporate codes of conduct and monitoring social governance civil society pressure on business from labor organizations and non governmental organizations and public governance government policies to support gains by labor groups and environmental activists this new form of synergistic governance is illustrated with evidence from recent studies of gvcs and industrial clusters as well as advances in theorizing about new patterns of governance in gvcs and clusters

land tenure and investment incentives evidence from west africa abstract the existing literature on the relationship between property rights in land and agricultural investment in africa has given results that are often confusing and contradictory i make two clarifying contributions to this literature first i pull together existing studies and investigate whether the results they find have been affected by research methods or local contexts studies with small sample sizes those that use binary investment measures and those that control for household fixed effects are less likely to find a statistically significant link between land tenure and investment self reported tenure security has been a poor predictor of investment outcomes second i test for a relationship between land tenure and agricultural investment in nine data sets from west africa while the link between tenure and investment is significant for fallow and tree planting it is less robust for labor use and other inputs such as manure or chemical fertilizer

shocks and asset dynamics in ethiopia abstractthis article uses household survey panel data of 416 rural households to study asset dynamics in the northern highlands of ethiopia and the response of assets to shocks the period under examination 1996 2003 was marked by severe environmental shocks including a series of droughts the article empirically studies the nature of household asset paths over time using as the point of departure the theory on precautionary savings behavior results indicate that the response of assets to weather shocks the differential effect of these shocks on liquid and less liquid forms of wealth holdings and the nature of asset dynamics are all consistent with the implications of a precautionary motive for holding wealth

natural disasters and labor markets abstract while it is clear that natural disasters have serious welfare consequences for affected populations less is known about how local labor markets in low income countries adjust to such large shocks combining data from the indonesia family life survey the desinventar database the u s geological survey and district level employment indicators this paper explores how a large earthquake in indonesia affected labor market outcomes in particular the evolution of wages across sectors i find that the earthquake had a positive effect on wage growth for workers who were employed in the agricultural sector at baseline i propose two mechanisms for this result a higher growth rate of the price of rice and a downward shift in the supply of workers in the agricultural sector i show that evidence mainly supports the latter labor shifted out of the agricultural sector into the construction sector raising the marginal product of labor in agriculture

pathology of path dependency the ilo and the challenge of new governance using archival sources the authors study strategic and organizational change in the international labour organization ilo over the last twenty years they focus specifically on the ilo s efforts to incorporate certain elements of the new governance model into its policies and organizational practices which include the shift from standards expressed as detailed legal norms to soft law the active involvement of civil society organizations other than trade unions and employer associations in regulatory activities and the introduction of quantitative indicators of compliance with labor standards they argue that the efforts of the ilo leadership have been waylaid by the organization s corporatist structure which gives employer associations and trade unions veto power over policy developments at a time in which these actors are increasingly unable to agree on concrete policy measures finally the authors ask whether this corporatist structure accurately reflects the ilo s self defined mission prov

combining global and local forces the case of labor rights in cambodia summary an innovative policy experiment in cambodia links improvement of workers rights with increased orders and market access for the products of the country s garment factories the policy originated with the us cambodia textile agreement which awarded cambodia higher garment export quotas into the us market in return for improved working conditions and labor regulations it has continued even after the expiration of the global garment quota system at the end of 2004 the agreement s effectiveness has depended on the international labor organization acting as a compliance monitor and government intervention preventing some apparel producers from free riding on others improvements

emissions trading and investment decisions in the power sector a case study in finland abstract organizations which consider investment in or divestment of power production licences capacity within the european community are exposed to the impacts of the european union emission allowance trading scheme eu ets in this paper the consequences of the eu ets on investment decisions are explored in a country specific setting in finland first we review the general mechanisms through which the eu ets influences size timing and cashflows of an investment next we discuss the projected changes in finnish power producers investment environment and examine the financial impacts due to the eu ets on a case investment decision a hypothetical condensing power plant 250 mwe the standard discounted cash flow dcf analysis is extended to take into account the value of two real options the option to wait and the option to alter operating scale in a quantitative investment appraisal the impact of emissions trading not only depends on the expected level of allowance prices but also on their volatility and correlation with electricity and fuel prices the case study shows that the uncertainty regarding the allocation of emission allowances is critical in a quantitative investment appraisal of fossil fuel fired power plants

imperfect commitment altruism and the family evidence from transfer behavior in low income rural areas in this paper we examine empirically whether risk pooling is more advantageous among altruistic compared to selfish agents in a framework where individuals cannot make binding commitments in particular we incorporate altuism into a model of risk sharing under imperfect commitment and use simulation methods to establish tests of the roles of both altruism and commitment problems in determining the extent of insurance and the intertemporal movements in interhousehold transfers the tests are carried out using three panel data sets from two countries of rural south asia that provide detailed information on transfers and enable the measurement of income shocks the estimates provide strong support for the notion that imperfect commitment substantially constrains informal transfer arrangements whether kin based or not but also provide evidence that altruism plays an important role in ameliorating commitment constraints and thus in increasing the gains from income pooling
