what explains wage gaps between farm and city exploring the todaro model with american evidence 1890 1941 nominal wage gaps between farm and city employment are one of the most pervasive aspects of modern economic growth so much so that they have become a key stylized fact of development economics indeed a good portion of the literature on the third world has focused on this problem at length both in terms of labor market behavior and in terms of policy formation in the face of factor market distortions yet wage gaps are not simply an institutional peculiarity of newly industrializing third world countries since they seem to have been even greater among nineteenthand twentieth century western nations while unskilled full time nominal city wages are about 41 higher than farm wages in the contemporary third world they were about 51 higher among late nineteenth century industrializers they were even higher in england in the 1830s about 73 2 furthermore the evidence suggests that these wage gaps vary substantially over time they rose from 29 to 41 in the american north between the antebellum and postbellum periods and were about 50 by the mid 1890s in the united states as a whole a figure that reached an all time u s high of about 65 by the late 1930s 3 there are three questions that these wage gaps raise not just one first would these nominal full time wage gaps disappear if they were properly measured proper measurement would include the fact that cities are more costly places to live that cities may have greater disamenities that farmers also make in kind payments to their workers and that farm laborers suffer seasonal underemployment elsewhere

market based biogas sector development in least developed countries the case of cambodia in many of the least developed countries the energy security conundrum is how to provide affordable safe and clean energy to a low income rural population household level generation of biogas from animal waste for both cooking and lighting while producing high quality organic fertiliser is increasingly proposed as a viable part of the solution for farming households since the early 1990s international development organisations often in cooperation with the national government have attempted to introduce biogas technologies in many least developed countries but most initiatives failed in this landscape of failed biogas development programmes the national biodigester programme nbp cambodia started in 2006 with the aim to establish a permanent market oriented and self financed biogas sector the results show the development of a sustainable domestic biodigester sector a rapid diffusion of biodigesters among poor rural households but still ambivalences on financial independency from external funding and carbon finance the conclusion is that a pure market model for biogas development in the rural area of the least developed countries will not easily work governmental regulation and coordination will remain needed and carbon finance will not easily fully replace oda and governmental financial support

the value of cooperatives in rural electrification the electricity sectors of many developing countries underwent substantial reforms during the 1980s and 1990s driven by global agendas of privatization and liberalization however rural electrification offered little by way of market incentives for profit seeking private companies and was often neglected as a consequence delivery models for rural electrification need to change this paper will review the experiences of various rural electrification delivery models that have been established in developing countries including concessionary models dealership approaches and the strengthening of small and medium sized energy businesses it will use examples from the usa bangladesh and nepal together with a detailed case study of a nepali rural electric cooperative to explore the role that local cooperatives can play in extending electricity access it is shown that although there is no magic bullet solution to deliver rural electrification if offered appropriate financial and institutional support socially orientated cooperative businesses can be a willing efficient and effective means of extending and managing rural electricity services it is expected that this paper will be of particular value to policy makers donors project planners and implementers currently working in the field of rural electrification

biogas energy from family sized digesters in uganda critical factors and policy implications dependence on fossil energy sources is increasingly becoming unsustainable due to ecological and environmental problems and rapid depletion biogas energy could augment these conventional energy sources but despite its advantages and favourable conditions for its production biogas energy use in uganda remains low due to technical economic and socio cultural impediments based on primary data on households in central and eastern uganda and the use of logistic regression this study analyses factors affecting the adoption of biogas energy in uganda the empirical results suggest that the probability of a household adopting biogas technology increases with decreasing age of head of household increasing household income increasing number of cattle owned increasing household size male head of household and increasing cost of traditional fuels in contrast the likelihood of adoption decreases with increasing remoteness of household location and increasing household land area policy options and recommendations including educational and awareness campaigns on biogas benefits and successes the provision of financial and non financial incentives to households and establishment of an institutional framework could bolster wider biogas energy acceptance in uganda

modern energy access to all in rural india an integrated implementation strategy abstract expanding energy access to the rural population of india presents a critical challenge for its government the presence of 364 million people without access to electricity and 726 million who rely on biomass for cooking indicate both the failure of past policies and programs and the need for a radical redesign of the current system we propose an integrated implementation framework with recommendations for adopting business principles with innovative institutional regulatory financing and delivery mechanisms the framework entails establishment of rural energy access authorities and energy access funds both at the national and regional levels to be empowered with enabling regulatory policies capital resources and the support of multi stakeholder partnership these institutions are expected to design lead manage and monitor the rural energy interventions at the other end trained entrepreneurs would be expected to establish bioenergy based micro enterprises that will produce and distribute energy carriers to rural households at an affordable cost the escos will function as intermediaries between these enterprises and the international carbon market both in aggregating carbon credits and in trading them under cdm if implemented such a program could address the challenges of rural energy empowerment by creating access to modern energy carriers and climate change mitigation

exit and inefficiency the effects of ownership type this study uses data on hospital closures to examine the relation between exit and inefficiency in an industry where for profit not for profit and government firms coexist the likelihood of hospital exit over the period 1986 91 is estimated as a function of hospital relative inefficiency ownership type and other factors where hospital relative inefficiency is measured using residuals from estimation of a stochastic frontier cost function we find that less efficient hospitals were more likely to exit when ownership was for profit or not for profit but that relative inefficiency did not have a significant effect on the probability of exit for government hospitals

cost and efficiency in nursing homes a stochastic frontier approach abstract the average level of cost inefficiency in new york nursing homes is estimated at 29 based on a two year panel of 164 skilled nursing facilities and 443 combination skilled and health related facilities the stochastic frontier cost function is fit to the data utilizing the composed error model wherein statistical noise and allocative and technical inefficiency are jointly estimated there is no change in efficiency between 1987 and 1990 and it does not vary between for profit and not for profit homes excessive managerial and supervisory personnel and diseconomies of size are linked to inefficient operation chronic excess demand is suggested as a cause of the high level of inefficiency

are the energy poor also income poor evidence from india abstract the energy poverty line is defined as the threshold point at which energy consumption begins to rise with increases in household income this approach is applied to cross sectional data from a comprehensive 2005 household survey representative of both urban and rural india the objective is to determine if the energy poor are also income poor and whether and how energy policies help reduce energy poverty independent of income the findings suggest that in rural areas some 57 of households are energy poor versus 22 that are income poor but in urban areas the energy poverty rate is 28 compared to 20 that are income poor that is energy policies are expected to play some roles in mitigating energy poverty we find that reducing energy poverty requires not only support for rural electrification but also more use of modern cooking fuels such as lpg while income growth matters a combination of energy related programs can play an independent and substantial role in reducing energy poverty

drivers barriers and strategies for implementation of renewable energy technologies in rural areas in bangladesh an innovation system analysis abstract bangladesh has good potential for harnessing renewable energy sources such as solar biomass wind and mini hydropower the country has been experiencing a gradual shift towards exploring renewable energy resources as a driving force for rural development a few public sector and non government organizations have started to develop renewable energy technology ret projects in rural areas the lessons learnt from different demonstrations of ret projects reveal that with careful forward planning renewable energy can provide far reaching economic environmental and social benefits to people living in remote rural areas in bangladesh this paper identifies some of the barriers that need to be overcome for the successful development of renewable energy technology sector and betterment of rural livelihoods it does so through a critical review of policy and institutional settings as well as present status and lessons learnt from pilot demonstration of a number of ret projects undertaken by different organizations the study highlights policy implications of the review with the aim of supporting decision makers in formulating renewable energy policies and future plans for bangladesh

the development of renewable energy power in india which policies have been effective abstract the international energy agency has identified the development of renewable energy sources as a key element to mitigate climate change at the same time it has projected india to be the second largest contributor to the increase in global energy demand to 2035 india hence faces a significant challenge to ensure its energy security by diversifying its power generation mix in the wake of the creation of a green climate fund in cancun this paper studies empirically the effect of the introduction of the electricity act 2003 and the tariff policy 2006 as well as the implementation of feed in tariffs and minimum quotas on clean electricity sourcing on the development of grid connected renewable energy power in nine indian states over the period 2001 2009 results suggest that the passing of the tariff policy 2006 state level policies quantity based instruments and a greater participation of the private sector have played a key role in promoting the development of installed capacity from renewable energy power in the nine states of the sample

measuring hospital efficiency with frontier cost functions this paper uses a stochastic frontier multiproduct cost function to derive hospital specific measures of inefficiency the cost function includes direct measures of illness severity output quality and patient outcomes to reduce the likelihood that the inefficiency estimates are capturing unmeasured differences in hospital outputs models are estimated using data from the aha annual survey medicare hospital cost reports and medpar we explicitly test the assumption of output endogeneity and reject it in this application we conclude that inefficiency accounts for 13 6 percent of total hospital costs this estimate is robust with respect to model specification and approaches to pooling data across distinct groups of hospitals

off grid electricity interventions for cleaner livelihoods a case study of value chain development in dhenkanal district of odisha lack of access to electricity in rural areas hinders productive activities which in turn affects sustainable rural development off grid electrification options can offer an alternative but in order to develop productive uses of electricity in off grid area a detailed study of livelihoods and potential areas for improvement in the value chain is required this paper reports such a study where a livelihood baseline survey was undertaken in a cluster of five remote off grid villages in dhenkanal district of odisha india and through a series of interviews focused group meetings and stakeholder interactions the study finds that value added services can be developed through an off grid electrification intervention electrification can support productive activities thereby offering an opportunity for improved income generation and a better quality of life and a transition to cleaner energy sources the study provides a novel value chain framework for linking off grid projects with local livelihoods replicable across multiple geographies ensuring sustainability of these projects

household cooking fuels and technologies in developing economies abstract a major energy challenge of the 21 st century is the health and welfare of 2 7 billion people worldwide who currently rely on burning biomass in traditional household cooking systems this special issue on clean cooking fuels and technologies in developing economies builds upon an iaee workshop on this subject held in istanbul in 2008 foell et al 2008 it includes several papers from that workshop plus papers commissioned afterwards the major themes of that workshop and this special issue are analytical and decision frameworks for analysis and policy development for clean cooking fuels making energy provisioning a central component of development strategies strategies business models of suppliers of modern fuels and technologies analysis of successes failures of past policies and programs to improve access to clean cooking this introductory paper serves as a preamble to the 11 papers in this special issue it provides a brief background on household cooking fuels and technologies including 1 their implications for sustainable development health and welfare gender impacts and environment climate issues 2 options and scenarios for improved household cooling systems and 3 discussions of institutions programs and markets it closes with research and action agendas initially developed during the 2008 workshop

switching costs and sectoral adjustments in general equilibrium with uninsured risk abstract consider a two sector economy subject to recurring technological shocks these affect earnings in the two sectors differently creating incentives for workers to switch occupation switching costs are sunk individuals are risk averse and cannot diversify their income risk we characterize the rational expectations equilibrium of the economy and illustrate the extent to which uncertainty and switching costs increase labor immobility the resulting equilibrium is not even second best optimal even a government that cannot transfer income to achieve insurance can improve matters by speeding up the reallocation of labor across sectors because that reduces relative price variability journal of economic literature classification numbers d52 d62 j62

terms of trade risk with partial labor mobility abstract we examine the welfare consequences of terms of trade risk in a small open economy in which it is costly for workers to move between sectors relocation costs lead to partial labor mobility sectoral wage gaps and income risk exceeding that of an economy in which relocation is costless using observed wage differentials and standard values for volatility and preferences we find that the welfare cost of partial labor mobility alone is unlikely to be very large even in the absence of self insurance arrangements in addition modest consumption substitution elasticities significantly reduce these welfare costs

analysis of the energy access improvement and its socio economic impacts in rural areas of developing countries abstract access to modern energy is one of the most basic requirements for development in rural areas of developing countries there are a large number of people who do not have access to lpg and depend on traditional biomass such as wood crop and dung for cooking in addition energy has numerous and complex links with poverty reduction therefore it is important to estimate the impacts of energy access improvement on socio economic situation in the rural areas of developing countries quantitatively this study focuses on socio economic impacts of cooking demand through changes in stoves adopted by the rural households we have developed an energy economic model of rural areas in india to analyze the links between energy income and health hazard applying both opportunity cost for using fuelwood and exposure to resipirable suspended particulate matter rspm as a result of the analysis there is a positive relation between the opportunity cost and the average rspm exposure of women in the rural areas following to increase in the opportunity cost that is income the cost of an improved wood stove becomes relatively lower first than that of a traditional wood stove and then a gas stove attains price competitiveness it is achieved that the average rspm exposure is below the who and japanese criteria for suspended particulate matter spm 190 and 100 g m3 at the opportunity cost of us 9 and 15 gj respectively

prospects for expanded utilization of biogas in germany the prospects for expanded utilization of biogas systems in german was analysed by identifying the operational and policy factors affecting the complete chain of processes from implementation process for biogas plants through to biogas production and utilization it was found that the renewable energies act eeg and energy tax reliefs provide bases for the support of expanded utilization upgrading of biogas to natural gas quality for utilization in the transportation sector was arguably the most promising technology that could support rapid utilization expansion sustainable deployment of biogas systems in light of the unstable feedstock prices and availability and the need for subsidy free operation in the long term requires enhancement of feedstock flexibility and quality characteristics to maximise gas yield and optimisation of the anaerobic digestion process management assessment of energy balance and potential environmental impacts of the integrated process chain provides a holistic assessment of sustainability the results also support the development and foster of policies and framework for development of biogas as environmentally friendly energy resource among a mix of renewable energy sources hence compete favourably with fossil fuels to enhance the prospects for expanded utilization

welfare gains from international risksharing abstract this paper uses consumption data to compute yet unexploited welfare gains that can be achieved through risksharing among twenty oecd countries there is both aggregate national consumption risk and nondiversifiable individual specific risk countries engage in an optimal risksharing arrangement to pool risk associated with the aggregate consumption endowment streams welfare gains are associated with reduced consumption variability and with the international pricing of the consumption streams of individual countries the paper considers the standard vnm time additive preferences as well as nonexpected utility and habit formation preferences large unexploited gains are found under all sets of preferences leading to an international risksharing puzzle

understanding the political economy and key drivers of energy access in addressing national energy access priorities and policies abstract globally 1 5 billion people lack access to electricity and nearly 3 billion lack access to modern cooking energy options of the world s energy poor 95 are in asia and sub saharan africa within asia almost 80 of electricity deprived and 86 of biomass dependent populations are in the big 5 countries bangladesh china india indonesia and pakistan in this paper we discuss the broad contours of the political economy of energy access in these countries the political economy is assessed through an examination of three sustainability objectives accessibility of physical infrastructure energy service delivery and conformance to social goals the key areas of concern include emphasis on supply driven grid electricity vested power dynamics favouring affluent and urban areas unreliability of energy service provision and misdirected and misappropriated subsidies the above mentioned issues are responsible for limiting accelerated achievement of universal energy access in the big 5 countries and need to be addressed through innovative approaches the paper emphasizes the need for firm commitments policy convergence and the implementation of pro poor equitable energy policies through a broad based energy framework of bench marked technology neutral energy provisioning that ensures reliability and equity it highlights the need for reorienting of the subsidy regime and incorporating energy service delivery indicators in monitoring and reporting mechanisms

what do stochastic frontier cost functions tell us about inefficiency abstract recent studies using the stochastic frontier approach have suggested high levels of inefficiency in nursing home and hospital facilities this paper makes two observations first one could falsely estimate high levels of inefficiency if a statistical assumption zero skewness of the random component of the cost residual is violated second an inefficient industry may be difficult to distinguish either statistically or visually from an industry free of inefficiency if available panel data yields more robust estimates of cost differences among nursing homes or hospitals

structural adjustment to a terms of trade disturbance the role of relative prices abstract this paper investigates the impact of a terms of trade disturbance on a small economy which responds gradually to changes in relative prices the key intertemporal link is as in dornbusch 1983 between the price of nontraded goods the real interest rate savings and the current account if the traded and nontraded goods are bad substitutes in consumption then an improvement in the terms of trade leads to a transitory current account surplus and conversely international capital mobility reduces the impact of a terms of trade disturbance on relative prices and also reduces the speed with which the economy adjusts to the disturbance

the implementation of decentralised biogas plants in assam ne india the impact and effectiveness of the national biogas and manure management programme abstract the indian government s national biogas and manure management programme nbmmp seeks to deliver renewable energy services to households across the country by facilitating the deployment of family sized 3 anaerobic biogas digesters nbmmp policy is implemented at three levels from government and state nodal agency via private contractors to households creating multiple institutional arrangements we analysed the scheme in assam north east india focusing on how policy was implemented across two districts and interviewing stakeholders in rural households state and non state institutions the top down supply side approach to policy enables government to set targets and require individual states to deploy the scheme which benefits households who can afford to participate nbmmp delivered improved energy service outcomes to a majority of households although the level of knowledge and understanding of the technology amongst users was limited training and education of householders and particularly women is needed in relation to the maintenance of digesters feedstock suitability and the environmental and potential livelihood benefits of digestate a revised bottom up approach to policy which highlights the contextual and demand side issues around adopting the technology may deliver monetary benefits from market competition and enable development of community focused microfinance schemes to improve the affordability of biogas systems

exit from the hospital industry we study the exit of hospitals from the market for inpatient services more generous hospital reimbursement significantly reduces the probability of exit throughout the 1990s conditional on reimbursement levels hospital efficiency was not a significant determinant in the early 1990s but in the mid to late 1990s less efficient hospitals were significantly more likely to exit throughout the period high tech services increased the probability of survival and for profit hospitals were more likely to exit the role of medicare as a determinant of exit became less important in the latter half of the 1990s

financing energy access and off grid electrification a review of status options and challenges abstract this paper provides a review of funding needs and financing mechanisms for energy access in general and off grid electrification in particular to find whether the funding for these activities has been adequate whether sufficient funding is likely to be available to meet the needs of universal energy access whether innovative approaches can be used in funding it finds that in all successful cases the state has played an important role in funding infrastructure investments but many developing countries have neglected the energy access issue for a long time international donor agencies have provided selective and limited support while the innovative mechanisms are also unfriendly towards small scale projects weak governance limited organisational capacity and unfavourable policy environment militate against large scale mobilisation of financial resources in the poorest countries of the world where energy access is a chronic problem the challenge of mobilising finance and ensuring its appropriate delivery and use remains a major issue and would require a co ordinated effort of all relevant stakeholders

evaluating tradable property rights for natural resources the role of strategic entry and exit this paper presents an econometric approach to the evaluation of environmental regulation using tradable property rights existing empirical research on this issue which compares overall industry efficiency before and after the introduction of new regulations conflates two distinct phenomena efficiency changes due to exit of excess capital and changes in the efficiency of individual firms because the regulatory process induces firms of different types to enter and exit the industry at different rates the true efficiency and equity effects of tradable property rights cannot be assessed without correcting for these changes in sample composition this paper examines the impact of regulatory change in the mid atlantic surf clam fishery using an econometric model that separates its effects on industry structure and vessel efficiency the analysis finds that contrary to widely held belief tradable property rights did not disproportionately benefit either large fishing firms or highly integrated firms

profit variability in for profit and not for profit hospitals this paper proposes two tests of the hypothesis that not for profit hospitals nfps behave differently than for profit hospitals the profit variability test states that the profits of an nfp will be less variable over time than profits of a for profit hospital if the nfp maximizes utility subject to a profit constraint the second test examines whether nfp profits respond less to change in exogenous factors such as medicare reimbursement rates than profits of for profit hospitals both tests performed on panel data from 1983 to 1988 support the hypothesis that nfps behave differently than for profit hospitals

us based ngos in international development financial and economic determinants of survival summary the accountability of non governmental organizations ngos has various dimensions from an economic perspective official financiers private donors as well as aid recipients could expect more charitable output from ngos if less efficient organizations were squeezed out of international development activities we consider administrative overheads as an important aspect of ngo efficiency our empirical analysis focuses on the effects of administrative overheads public funding and the interrelations between these two factors on the probability of market exit for almost 900 us based ngos with overseas aid activities since the mid 1980s we find that larger administrative overheads increase the probability of exit for ngos receiving any public funding however this effect weakens with increasing shares of public funding of ngos

access and affordability of electricity in developing countries summary a key objective of developing countries is to provide affordable access to modern energy services in order to support economic and social development the paper presents a number of arguments for why and in which way energy access and affordability can play a key role in national development programs and in achieving the millennium development goals approaches for measuring accessibility and affordability are presented drawing on case studies of bangladesh brazil and south africa countries with different rates of electrification affordability of using electricity is examined in relation to the energy expenditure burden for households and time consumption conclusions focus on lessons learned and recommendations for implementing policies instruments and regulatory measures to tackle the challenge of affordability
