access to markets and rural poverty evidence from household consumption in china abstract this paper presents evidence on the effects of access to domestic and international markets on per capita consumption of households using data from rural china the econometric analysis uses alternative identification schemes to address the potential endogeneity of access to markets we use straight line distances to coastline and navigable river along with the topography of the intervening counties as sources of exogeneous variations we also use identification through heteroskedasticity which does not rely on standard exclusion restrictions the results from alternative identification schemes show that better access to both domestic and international markets has positive effects on per capita consumption the domestic market effect is significantly larger in magnitude and there is complementarity between the access to domestic and international markets

the impact of biogas technology adoption for farm households empirical evidence from mixed crop and livestock farming systems in indonesia abstract this paper aims to study the impact of biogas technology adoption as a livestock waste technology to support mixed crop and livestock mcl farming among smallholder farmers in indonesia a cross sectional survey was conducted to collect data from 351 farm households 171 biogas adopters and 180 non adopters in the province of yogyakarta this study employed treatment effects analysis based on propensity score matching techniques to evaluate the impacts of biogas technology adoption among the farm households the results showed that the adoption of the biogas technology reduces firewood consumption of smallholder farm households in indonesia unfortunately the impact on the use of slurry for organic fertilizers and the use of gas liquid petroleum gas lpg as another household cooking energy could not be evaluated this study empirically showed that the benefits of the biogas technology had not yet been optimized at the household level which may partly explain the slow rate of biogas technology diffusion among farmers however the consumption reduction of firewood as a benefit of using biogas contributed to behavioral changes of the women in the households especially with respect to firewood collection and cooking activities

games of fair division abstract we consider the problem of fairly allocating an indivisible good to one of several agents equally entitled to it when monetary compensations to the others are possible our primary normative concept is no envy first we show that there is no non manipulable selection from the no envy solution then we study the direct revelation games associated with subsolutions of the no envy solution the set of equilibrium allocations of any one of them coincides with the set of envy free allocations for the true preferences journal of economic literature classification numbers c72 d63 d7l d82

land tenure arrangements and rural urban migration in china summary obstacles to internal migration in china contribute to inefficiency inequality and land degradation academic and policy debate has primarily focused on discrimination against rural migrants on arrival in urban areas meanwhile barriers to migration out of rural areas have received less attention this paper examines the role of incomplete rural property rights in the migration decisions of rural households we examine the relationship between tenure insecurity and restrictions on land rentals and participation in outside labor markets the results indicate that tenure insecurity reduces migration this relationship is particularly pronounced on forest land which has implications for the conservation of recently replanted forest areas

how urban segregation distorts chinese migrants consumption summary this paper provides a new explanation for china s low consumption to gdp ratio by highlighting the constraints of the household registration system hukou on china s household consumption our baseline results show that the consumption of migrants is 16 20 lower than that of local urban residents we further find evidence suggesting that caused by hukou restrictions migrants save more for precautionary purposes have lower expectation of permanent income and consume much less durable goods because of high mobility moreover we have found no evidence that the consumption heterogeneity can be explained by migration effects culture or other forms of household heterogeneity as both the number and income level of migrants are rising quickly the constraining effects of hukou on household consumption is increasing 2014 elsevier ltd all rights reserved

inside china s cities institutional barriers and opportunities for urban migrants one of the most glaring legacies of 20thcentury chinese socialism is a sharp and widened divide between china s urban and rural areas china s widened urban rural divide arose from a socialist industrialization process which created a hastened heavy industrial base at the expense of its rural population china s vast rural population not only endured a standard of living far below that in the urban sector they were also denied access to many social welfare benefits and social mobility opportunities martin king whyte 1996 this urban rural gap in social and economic wellbeing together with a massive reservoir of rural surplus labor and an acute shortage of consumer goods formed the driving forces for china s change of migration control policy and for the rapid increase of rural migrants in chinese cities though the exact number of migrants is still hard to ascertain due to both a lack of consensus in the definition of migrant and the absence of an authoritative national survey migrants prominent presence in chinese cities is hardly disputable in china s largest cities for instance it is often quoted that at least one out of every five persons is a migrant and most likely a migrant from rural areas in shanghai the number of migrants rose tenfold in one decade from 0 26 million in 1981 to 2 81 million in 1993 the percentage of local residents who were migrants correspondingly rose from less than 5 percent in the early 1980 s to 21 7 percent in 1993 changming sun 1997 in beijing the number of migrants was 3 29 million in 1994 compared to a locally registered population of 10 63 million for the whole municipality and 6 million for its city districts dangsheng ji et al 1996 p 95 in city districts one out of every three persons in beijing is a temporary migrant from elsewhere most of these recorded migrants are also genuine migrants not short term visitors more than 60 percent had stayed for more than half of a year and only 17 percent had been in beijing for less than one month three quarters of all the surveyed migrant population listed business or employment as their purpose of stay ji et al 1996 pp 96 97 rural migrants account for over threequarters of all migrants in large chinese cities in shanghai for instance a survey in 1995 found that 88 1 percent of all migrants had their place of household registration in the countryside wang and zuo 1997 similarly in beijing where one expects to see a higher circulation of urban to urban migrants close to 80 percent of migrants surveyed in late 1994 were peasants before moving into beijing xiuhualiu 1996 p 112

migration theories and evidence an assessment abstract this paper presents a critical survey of theories of migration their welfare and policy implications and their empirical relevance we also develop some extensions to the theory beginning with the harris and todaro ht model in particular the ht model is extended to examine risk averse behaviour within families where the migration of members of families serves to diversify risk the welfare implications of the individual migration decision and government intervention in the form of employment subsidies are examined recent evidence on international migration is presented it is shown that migration does not flow automatically in response to wage differentials characteristics of migrants and the process of self selection are found to be important determinants of the rate of migration

from linear fuel switching to multiple cooking strategies a critique and alternative to the energy ladder model abstract promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy efficient and less polluting cooking stoves and practices the transition from traditional to modern fuels and devices has been explained by the energy ladder model that suggests that with increasing affluence a progression is expected from traditional biomass fuels to more advanced and less polluting fuels in this paper we evaluate the energy ladder model utilizing data from a four year 1992 96 case study of a village in mexico and from a large scale survey from four states of mexico we show that an alternate multiple fuel model of stove and fuel management based on the observed pattern of household accumulation of energy options rather than the simple progression depicted in the traditional energy ladder scenario more accurately depicts cooking fuel use patterns in rural households the multiple fuel model integrates four factors demonstrated to be essential in household decision making under conditions of resource scarcity or uncertainty a economics of fuel and stove type and access conditions to fuels b technical characteristics of cookstoves and cooking practices c cultural preferences and d health impacts this model also allows better estimates of the expected fuelwood demand and indoor air pollution in rural households

the approach to realizing the potential of emissions reduction in china an implication from data envelopment analysis abstract by proposing a three hierarchy meta frontier data envelopment analysis dea this paper first decomposes co 2 emissions efficiency and the potential for emissions reduction into the following three components structural technical and management based on these components we then conduct an empirical analysis of china s total factor co 2 emissions efficiency its potential for co 2 emissions reduction and its corresponding implementation path the results show that co 2 emissions efficiency in mainland china is relatively low because of structural inefficiency technical inefficiency and management inefficiency the chinese government is expected to realize a large quantity of co 2 emissions reduction potential nearly 40 of the current total co 2 emissions through adjusting the industrial structure narrowing the technology gap among regions promoting the reform of marketization and strengthening environmental regulation the causes of co 2 emissions inefficiency and the distribution of potential reductions in emissions show a distinct spatial difference characteristic therefore this paper also formulates emissions reduction strategies for china s 30 provinces according to their specific situations noting the direction of the industrial structure adjustment and the path to improving co 2 emissions efficiency

which factors are effective for farmers biogas use evidence from a large scale survey in china the chinese government since 1995 has carried out programs for the construction of household biogas digesters in the chinese countryside despite the large governmental spending in the building of household biogas digesters only 12 16 of the households suitable to produce and use biogas have built a digester li 2009 this article asks which factors on the household level may be important for the decision whether or not to build a biogas digester based on a survey with 1227 households from guangxi hubei shandong and gansu provinces results of a binary probit model show that the governmental promotion of biogas has a significant effect on households decision the question arises which households may if governmental programs were to be running out be most likely to construct a household biogas digester the household head s age the number of household members staying at home the total household income and the subjective discount rate of the respondents are significant factors in a farm household s decision to build a biogas digester however also agro climatic conditions reveal to be decisive which is why technical solutions for tackling the low productivity of biogas digesters in cold regions may need to be further considered

a numerical simulation analysis of hukou labour mobility restrictions in china abstract we use numerical simulation methods to analyze the hukou system of permanent registration in china which many believe has supported growing relative inequality over the last 20 years by restraining labour migration both between the countryside and urban areas and between regions and cities our aim is to inject economic modelling into the debate on sources of inequality in china which thus far has been largely statistical we first use a model with homogeneous labour in which wage inequality across various geographical divides in china is supported solely by quantity based migration restrictions urban rural areas rich poor regions eastern central and western non coastal zones eastern and central western development zones eastern central western zones more disaggregated 6 regional classifications and an all 31 provincial classification we calibrate this model to base case data and when we remove migration restrictions all wage and most income inequality disappears results from this model structure points to a significant role for hukou restrictions in supporting inequality in china we then present a further model extension in which urban house price rises retard rural urban migration the impacts of removing hukou restrictions on migration are smaller but are still significant finally we modify the model to capture labour productivity differences across regions calibrating the modified model to estimates of both national and regional gini coefficients removal of migration barriers is again inequality improving but less so

a review on biogas technology and its contributions to sustainable rural livelihood in ethiopia abstract biogas technology has uneven dissemination over the globe the technology is at its infant stage of development and dissemination in many developing countries while china has the largest implementation record the principal factors controlling its dissemination include policies and institutions financial constraint subsidies availability of inputs awareness about the technology consumers considerations and success stories about the technology however biogas technology is a multipurpose technology which assists in addressing economic health social and environmental problems simultaneously thus development and dissemination of the technology certainly minimize energy poverty and improve peoples status in the energy ladder in line with this ethiopia has completed implementing the first phase 2009 2013 of its national biogas programme and has started implementing its second phase during the first phase it was able to disseminate 57 6 the total 14 000 domestic biogas plants planned for the period though the technology was introduced about five decades ago into the country biogas installations constructed prior to the establishment of the national biogas programme were having varied digester models lacked standards and central coordination and their entire number was not more than 1000 this paper reviews the status of dissemination of household biogas technology factors influencing the dissemination of the technology benefits of the technology at global scales energy resources consumption patterns and brief account of the technology at national scale ethiopia

regional energy efficiency carbon emission performance and technology gaps in china a meta frontier non radial directional distance function analysis abstract at present china is the largest primary energy consumer and carbon emitter in the world meantime china is a large transitional economy with significant regional gaps against such backgrounds the calculated results of energy and carbon performance indicators may be biased without considering heterogeneity across regions to this end after incorporating region heterogeneity this paper provides detailed information regarding energy efficiency carbon emission performance and the potential of carbon emission reductions from regional perspectives which may be important and useful for policy makers our main findings are as follows firstly there is significant group heterogeneity across regions in china in terms of energy efficiency and carbon emission performance secondly there are no considerable differences between total factor and single factor performance indices since there is limited substitutability between energy inputs and other production inputs finally significant carbon emission reductions can be made by catching up for regions with low energy efficiency and carbon emission performance looking ahead the chinese government should adopt measures to promote improvements in terms of energy efficiency and carbon emission performance in the short term

social identity and inequality the impact of china s hukou system abstract we conduct an experimental study to investigate the causal impact of social identity on individuals performance under incentives we focus on china s household registration hukou system which favors urban residents and discriminates against rural residents in resource allocation our results show that making individuals hukou identity salient significantly reduces the performance of rural migrant students relative to their local urban counterparts on an incentivized cognitive task and consequently significantly lowers their relative ranking in the earnings distribution under the piece rate regime however the impact of hukou identity salience is insignificant in the tournament regime suggesting that its negative effect on migrant students performance may be mitigated when competition is introduced the results demonstrate the impact of institutionally imposed social identity on individuals economic performance and potentially on inequality

the economic impact of medical migration an overview of the literature this paper provides an overview of the evidence and applied literature on medical migration the economic impacts of medical migration have been little researched causing a polarisation in the debate between its critics and its proponents the paucity of quantitative studies may be explained by the lack of comprehensive and consistent data investments in statistical resources on medical migration are therefore a major priority the available evidence suggests that particularly english speaking countries in sub saharan african countries and the caribbean with relatively few health workers and a high disease burden suffer most from the medical brain drain however the exodus of health workers is not the main cause of the health status crisis but rather a symptom of deeper underlying problems which often extend beyond the health sector towards the broader economic and political environment in such situations medical brain drain does pose challenges for human resource management and health service delivery the only effective and long term sustainable policy is one that addresses the underlying push and pull factors reforms have to be country led but may be supported via temporary migration schemes remittances enhancement of diaspora networks and financial aid for which a strong moral case exists

efficiency and distributional implications of global restrictions on labour mobility calculations and policy implications abstract in this paper a procedure for calculating the annual efficiency gains from various alternative changes in existing global immigration restrictions is presented along with an evaluation of impacts of wage rate changes on non migrating labour a simple methodology uses data on u s dollar gnp capita across countries to infer differences in the marginal productivity of labour both between countries and across major world trading areas two key assumptions used are that the worldwide labour supply is fixed and full employment occurs in all regions differences occuring in labour s marginal product across regions are assumed to arise because of barriers to inward mobility of labour in high wage countries when these are removed labour reallocates and efficiency gains occur while the calculations are based on contentious assumptions a striking feature is the size of the annual worldwide gains in some cases annual gains can easily exceed existing worldwide gnp generated in the presence of labour mobility restrictions while all gains do not accrue to ldc s the size of the gains nonetheless suggests that this issue may be much more important to these countries than other issues raised thus far in the north south debate the losses to labour already employed in high wage countries dramatize the incentives for labour unions in the developed world to oppose liberalization

immigration remittances and business cycles we use data on border enforcement and macroeconomic indicators from the united states and mexico to estimate a two country business cycle model of labor migration and remittances the model matches the cyclical dynamics of labor migration to the united states and documents how remittances to mexico serve an insurance role to smooth consumption across the border during expansions in the destination economy immigration increases with the expected stream of future wage gains but it is dampened by a sunk migration cost that reflects the intensity of border enforcement during recessions established migrants are deterred from returning to their country of origin which places an additional downward pressure on the wage of native unskilled workers thus migration barriers reduce the ability of the stock of immigrant labor to adjust during the cycle enhancing the volatility of unskilled wages and remittances we quantify the welfare implications of various immigration policies for the destination economy

the new economic case for migration restrictions an assessment abstract migration barriers tend to reduce global production by impeding efficient spatial reallocation of labor recent research argues for a countervailing effect of barriers tending to raise global production by preventing the spread of impoverishing institutions from poor to rich countries while evidence of this mechanism is scarce it is theoretically plausible at high migration rates we propose and calibrate a simple model of dynamically efficient migration when migrants spread economic institutions between countries the net effect of migration depends on three parameters transmission the degree to which origin country total factor productivity is embodied in migrants assimilation the degree to which migrants productivity determinants become like natives over time in the host country and congestion the degree to which transmission and assimilation change at higher migrant stocks on current evidence about the magnitudes of these parameters dynamically efficient policy would not imply open borders but would imply relaxation of current restrictions

where did all the remittances go understanding the impact of remittances on consumption patterns in rural china we focus on the impact of migrants remittances on consumption patterns in china using a large homogenous sample of rural households surveyed in 2001 and 2004 we find that remittances are spent on nonhousing consumption expenditures at the margin virtually dollar for dollar when we instrument remittances and local employed earnings using proxies of social networks our findings are robust to intra household division of labour and to fixed effect for the county in which the respondents are registered these results imply that rural households largely take remittances as permanent income and are consistent with the prevalence of circular and repeat migration in china

ethiopian power sector development renewable based universal electricity access and export strategies abstract this paper presents an assessment of alternative long term energy supply strategies for the ethiopian power sector during 2015 2045 using the markal energy system model this study also identifies alternative sustainable energy supply options to meet ethiopia s rising demand for energy while also achieving the policy goals of universal electrification zero greenhouse gas emissions increased electricity exports and improved energy security in all scenarios the results show a large potential for renewable energy technologies such as hydropower solar pv and wind these technologies have implications for neighboring countries in the region and will also affect the agriculture sector in ethiopia hydropower for example is a renewable energy source that can contribute to rural electrification while also providing water to support irrigation expansion an alternative policy scenario prioritizing renewable energy technologies reduces dependence on fossil fuel completely at minimal cost while providing long term environmental benefits expansion of electricity access to the entire population entails large investments in power generation capacity as well as substantial increases in the total system cost of energy production such a scenario would also increase the country s reliance on fossil fuels and geothermal energy sources most alternative policy options show higher investment costs will be required to achieve policy goals in the near term with the exception of the export scenario however the analysis shows long term benefits from investing in energy supply including sustainable energy system development expansion of access to modern sources of energy and the development of a low carbon society

moving off the farm land institutions to facilitate structural transformation and agricultural productivity growth in china agriculture has made major contributions to china s economic growth and poverty reduction but the literature has rarely focused on the institutional factors that might underpin such structural transformation and productivity this paper aims to fill that gap drawing on an 8 year panel of 1 200 households in six key provinces it explores the impact of government land reallocations and formal land use certificates on agricultural productivity growth as well as the likelihood of households to exit from agriculture or send family members to the non farm sector it finds that land tenure insecurity measured by the history of past land reallocations discourages households from quitting agriculture the recognition of land rights through formal certificates encourages the temporary migration of rural labor both factors have a large impact on productivity at about 30 percent each mainly by encouraging market based land transfers a sustained increase in non agricultural opportunities will likely reinforce the importance of secure land tenure which is a precondition for successful structural transformation and continued economic attractiveness of rural areas

mean variance analysis of supply chains under wholesale pricing and profit sharing schemes in this paper we explore the use of a wholesale pricing and profit sharing scheme wpps for coordinating supply chains under the mean variance mv decision framework we first analytically establish the necessary and sufficient conditions for coordinating the centralized supply chain by wpss we then show that there exists a unique equilibrium of the stackelberg game with wpps in the decentralized case after that we discuss the information asymmetric case in which the retailer can be benefited by pretending to be more risk averse finally we propose a new measure for the manufacturer to prevent this cheating from happening insights are generated

the link between renewable energy production and gross domestic product in africa a comparative study between 1980 and 2008 abstract renewable energy re projects are arguably one of the most important strategies that can be used in the mitigation of climate change impacts at the same time re technologies can generate clean energy and potentially boost the economy of the african continent it is thus not surprising that recent studies have investigated the relationship between re and economic growth in some african countries however the limitation of these reductionist analytical frameworks is that they can conceal the true regional picture in terms of the link between investments in re technologies and gross domestic product gdp this holistic analysis is important in order to inform regional policies on climate change the article uses statistical analytic techniques to examine the correlation between re production and economic growth across different blocks of the african continent between 1980 and 2008 the analysis is between geographical blocks e g southern africa western africa etc and between oil and non oil producing blocks generally speaking while there exists a similar pattern in all the studied blocks in terms of mean standard deviation and correlation between re and gdp a few exceptions can be found for instance the rise in re gdp correlation from 1992 1993 onwards was conspicuously higher in north africa and oil producing countries compared to all the other blocks similarly southern africa was the only block where the correlation between re and gdp was negative throughout the period under review except 1988 1989 and 1997 when it was positive

liberalising temporary movement of natural persons an agenda for the development round we discuss liberalising the temporary mobility of workers under mode 4 of the gats particularly the movement of medium and low skilled service providers between developing and developed countries such mobility potentially offers huge returns a flow equivalent to three per cent of developed countries skilled and unskilled work forces would generate an estimated increase in world welfare of over us 150 billion shared fairly equally between developing and developed countries the larger part of this emanates from the less skilled essentially because losing higher skilled workers cuts output in developing countries severely the mass migration of less skilled workers raises fears in developed countries for cultural identity problems of assimilation and the drain on the public purse these fears are hardly relevant to temporary movement however the biggest economic concern from temporary mobility is its competitive challenge to local less skilled workers but as populations age and the average levels of training and education rise developed countries will face an increasing scarcity of less skilled labour temporary mobility thus actually offers a strong communality of interest between developing and developed countries the remainder of the paper looks at the gats provisions on mode 4 and the commitments that have been made under it the paper reviews several official proposals for the doha talks including the very detailed one from india and considers several countries existing schemes for the temporary movement of foreign workers many countries have long had bilateral foreign worker programmes and some regional agreements provide for liberal and flexible movement these show what is feasible and how concerns can be overcome we caution that to be useful any wto agreement must increase mobility not just bureaucratise it the paper concludes with some modest and practical proposals we suggest inter alia that licensing firms to arrange the movement of labour is the most promising short term approach to increasing temporary mobility

dairy farming and biogas use in rungwe district south west tanzania a study of opportunities and constraints this study examined the opportunities and constraints of biogas use in rungwe district south west tanzania two hundred households with and without biogas facilities were selected randomly from four villages structured semi structured and open ended discussion was used to gather information findings show a number of opportunities for biogas technology adoption including large numbers of indoor fed cattle and inadequate firewood in the district which has increased its cost of such commodity households generally spend an average of tshs 20 656 50 per month or tshs 247 876 8 per annum for energy the demand for biogas 90 among respondents is high and the energy policy as well as donor community favour the promotion of energy efficient technologies such as biogas constraints encountered in establishing biogas plants were found to include unaffordability 75 and water scarcity also there is inadequate expertise where some of the biogas plants have been poorly constructed leading to ineffective performance there is also a small proportion of the respondents who admitted that they had heard nothing about biogas technology it is being suggested that credit should be available as well as developing affordable biodigestors communal biogas should be encouraged to reduce the cost per unit and the government should undertake the improvement of water services

rural domestic biogas supply model for zambia abstract there is potential of producing biogas in rural areas of zambia where rearing of cattle and other livestock exists with feedstock and financial resources people in rural areas could form groups or co operatives and install digesters with sizes ranging from 12 to 1000 m 3 generally the initial investment costs decrease with increase in digester size and decrease in the number of digesters to be installed economic analysis indicates that these digester sizes would be viable with positives net present values npvs at the nominal base rate of 18 up to about 37 when npvs start to be negative the payback period ranges from 1 3 years to about 3 years depending on size and investment costs biogas production results in an opportunity cost of us 0 01 kg dry dung biogas would replace the use of biomass for cooking energy needs currently burning of biomass on inefficient stoves leads to respirable particulate matter exposure ranges from 125 to 2125 g m 3 which is above the world health organization guidelines implementation of biogas production in the chitete settlement real case example would result into 3 022 ggco 2 eq avoided emissions from the use of biomass for cooking using inefficient stoves manure management and chemical fertilizer application conserve 9 48 t of nitrogen from avoided biomass consumption for cooking production of 336 t of organic fertilizer at a net income us 224 978 per year saving of 2171 t of firewood worth us 57 000 and 948 t of charcoal worth us 95 000 per annum

efficiency gains from liberalizing labor mobility in this paper we quantify the effect of a complete liberalization of cross border migration on the world gdp and its distribution across regions we build a general equilibrium model endogenizing bilateral migration and income disparities between and within countries our calibration strategy uses data on effective and potential migration to identify total migration costs and visa costs by education level data on potential migration reveal that the number of people in the world who have a desire to migrate is around 400 million this number is much smaller than that predicted in previous studies and reflects the existence of high incompressible migration costs in our benchmark framework liberalizing migration increases the world gdp by 11 5 12 5 percent in the medium term our robustness analysis reveals that the gains are always limited in the range of 7 0 percent with schooling externalities to 17 9 percent if network effects are accounted for

assessing the benefits to developing countries of liberalisation in services trade this paper discusses the potential impacts of services trade liberalisation on developing countries and reviews existing quantitative studies its purpose is to distill themes from current literature rather than to advocate specific policy changes the picture emerging is one of valiant attempts to quantify in the presence of formidable analytical and data problems yielding only a clouded image of likely impacts on trade consumption production and welfare emerging to the point that the policy implications of results are not always clear a central intuition would seem to be that with genuine two sided oecd non oecd liberalisation in services that are seemingly considerably labour intensive in delivery the potential should be there for significant developing country gains from global liberalisation allowing full cross border delivery however this picture is neither fully endorsed by available studies neither is it explicitly contradicted this seems to be the case for a number of reasons one difficulty with the studies is that the conceptual underpinnings of what determines trade in services and how this trade differs analytically from that of trade in goods if at all is an issue prior to assessments of impacts of liberalisation of trade in services on developing countries being discussed key issues here are the treatment of mobility for service providers both firms and workers and the differing analytical structures needed to analyse individual service items banking insurance telecoms etc some recent analytical work suggests that liber alisation in some service items such as banking need not always yield gains and this contrasts with quantitative studies where analytical structures mirror conventional trade in goods treatments the discussion and measurement of barriers to service trade in both developed and developing countries is also problematic one is talking of domestic regulation entry barriers portability of providers competition policy regimes more so than only barriers at national borders as with tariffs both representing and quantifying such barriers raise major difficulties and these are also spelled out in the paper which barriers actually restrict trade and which do not because they are redundant is one issue for instance it is also often misleading to represent barriers in simple ad valorem equivalent form as a result numerical modelling work on the effects of service trade barriers which is based on ad valorem equivalent modelling is often not fully convincing in addition individual country results vary considerably across studies in ways that it is frequently hard for outsiders to understand studies do however point towards a tentative conclusion that effects are small and positive for developed and most developing countries if fdi flow changes accompanying service trade liberalisation are excluded from the analysis but much larger and more variable across countries if they are present this could be taken to suggest that mode 3 gats liberalisation roughly captured in some studies might be important for developing countries but mode 4 gats liberalisation could be even more important given large barriers to labour flows across countries thus if service trade liberalisation is thought of primarily as a surrogate for improved functioning of global factor markets in which more capital flows to developing countries and more labour flows from them to developed countries then developing countries could benefit in a major way from genuine two sided oecd non oecd liberalisation developing countries fear however that in global negotiations on services liberalisation where there is an asymmetry of power that largely one sided liberalisation may be the outcome and their gains will be correspondingly limited the paper concludes by evaluating econometric studies on linkage between services liberalisation and country growth rules and briefly discusses some key sectoral issues in health services and transportation

technology adoption subsidies an experiment with managers we evaluate the impact of technology adoption subsidies on investment behavior in an individual choice experiment in a laboratory setting professional managers are confronted with an intertemporal decision problem in which they have to decide whether or not to search for and possibly adopt a new technology technologies differ in the per period benefits they yield and their purchase price increases with the per period benefits provided we introduce a subsidy on the more expensive technologies that also yield larger per period benefits and find that the subsidy scheme induces agents to search for and adopt these more expensive technologies even though the subsidy itself is too small to render these technologies profitable we speculate that the result is driven by the positive connotation affect that the concept subsidy invokes

will carbon motivated border tax adjustments function as a threat abstract due to large incremental carbon emissions china might become an important target country of cbta carbon motivated border tax adjustments to levy cbta could reduce china s emissions meanwhile china s emissions reduction could also be achieved by china s climate policies termed as cbta emissions equivalent policies this paper contributes to the discussion on cbta by comparing the potential regional effects of cbta and cbta emissions equivalent policies the main findings are as follows 1 cbta and cbta emissions equivalent policies would result in relocations of outputs across regions and countries affect the structure of economy and contribute to world s emissions reduction 2 there would be significant differences in the regional effects between cbta and cbta emissions equivalent policies 3 compared to carbon tax cbta would be a costly and inefficient policy instrument to reduce emissions but could function as an effective coercion strategy 4 these policies would result in competitiveness issue and rebound effects wherein different countries would be affected differently china is a large economy and energy consumer with high openness to international trade looking ahead the chinese government should consider the potential interactions between china and other economies when designing tax reforms

leaving the countryside rural to urban migration decisions in china this paper employs a simple theoretical model of labor allocation within rural households given existing land arrangements in an attempt to explain why rural chinese do not fully participate in labor migration it first explores the mechanisms by which individual household and community characteristics affect the migration decision empirical results are then presented to substantiate the derived hypotheses the paper further explores the question of whether the migration decision is permanent by analyzing the responses of household consumption to income from migration excerpt

implementation in undominated strategies a look at bounded mechanisms this paper examines the impact of placing natural restrictions on the mechanisms considered for implementation problems it is shown that if all mechanisms are considered and preferences satisfy a basic condition then any social choice correspondence can be implemented in undominated strategies an example points out that the strength of this result derives from the use of mechanisms with questionable features in part of the message space the agent who announces the highest integer is rewarded this sort of tail chasing construction common in the constructive proofs of the literature is used to assure that undesired strategy combinations do not form an equilibrium if such mechanisms are ruled out then the social choice correspondences which can be implemented in undominated strategies satisfy an incentive compatibility type condition called strategy resistence for social choice functions this is equivalent to strategy proofness this contrast suggests that this issue should be examined as it applies to other solution concepts used in implementation theory the last portion of the paper begins to explore the issue as it relates to nash implementation and undominated nash implementation

urbanization and urban systems in the people s republic of china research findings and policy recommendations this paper provides a literature review on urbanization in the people s republic of china prc research findings indicate that the prc s urbanization is incomplete its level of urbanization lags behind its industrialization and development status and while there are too many small cities the large cities are not large enough this is mainly because of the institutional constraints exerted by the hukou and land systems on labor mobility which have led to segregation efficiency loss distortion in the urban system and adverse impacts on equity as discussed in this study major policy recommendations are offered for removing the distortions and steering the prc s urbanization onto an efficient and equitable path

the higher educational transformation of china and its global implications higher educational transformation of china this paper discusses the major transformation of higher education that has been under way in china since 1999 and evaluates its potential global implications reflecting china s commitment to continued high growth this transformation focuses on major new resource commitments to tertiary education and significant changes in organisational form all of these changes have already had large impacts on china s higher educational system and are beginning to be felt by the global educational structure this focus on tertiary education differentiates the chinese case from other countries who earlier at similar stages of development instead stressed primary and secondary education

the higher educational transformation of china and its global implications this chapter documents the major transformation of higher education that has been underway in china since 1999 and evaluates its potential global impacts this has involved major new resource commitments to tertiary education and significant changes in organizational form reflecting china s commitment to continued high growth through quality upgrading and the production of ideas and intellectual property as set out in both the tenth 2001 2005 and eleventh 2006 2010 five year plans the number of undergraduate and graduate students in china has been growing at approximately 20 per year since 1999 and the total number of graduates at all levels of higher education in china has increased by more than a factor of six in the last decade entering class sizes and total student enrolments have risen fast too approximately quintupling prior to 1999 increases in these areas were much smaller much of the increased spending is focussed on elite universities and new academic contracts differ sharply from earlier ones which lacked tenure and often used annual publication quotas

a characterization of the shapley value in queueing problems a set of agents stand to receive a service no two agents can be served simultaneously a queue has been organized and agents having to wait should receive monetary compensations we characterize the rule assigning positions in the queue and compensations corresponding to the payoffs recommended by the shapley value of the associated cooperative game

interprovincial disparities in china output and consumption 1952 1987 the flood of economic information from china in recent years has permitted reassessment of the chinese model of development and the extent to which china s own development experience has conformed to it the prevailing consensus of the 1970s concerning the substance of the model itself typically characterized in terms of the chinese leadership s objectives and priorities and its strategy for pursuing them has stood up quite well the same cannot be said about past appraisals of the extent to which china s economic reality has been reshaped to accord with the model s prescriptions one of the most widely remarked elements of the chinese model is the high priority assigned to regional objectives and more specifically to balance in the distribution of productive capacity and equity in the distribution of income and hence consumption during the maoist era i e prior to 1979 the central government pursued regional objectives through such measures as interregional transfers of investment resources effected via the planning system subsidization of health and education expenditures in poor regions and attempts to maintain a safety net of state relief effected largely via control of grain surpluses in short there is little doubt that prior to 1979 the chinese leadership placed an unusually high value on the spread of modern growth and the improvements in welfare associated with it and persistently acted to limit the emergence or widening of interregional disparities although china s post mao leaders have shown greater concern with efficiency and with the potential trade offs between efficiency and such goals as balance and equity their continuation of many redistributive policies indicates that they have not abandoned regional objectives but how successful has china been in achieving these objectives

the evolution of the housing market and its socioeconomic impacts in the post reform people s republic of china a survey of the literature the development of the housing market in the people s republic of china is not only a major component of chinese economic growth but also has wide ranging influential impacts on chinese society a burgeoning number of papers have examined the housing market in the postreform people s republic of china from various perspectives this paper aims to provide a thorough survey of the key literature in the field and then supply a complete picture of the dynamics of the housing market in the people s republic of china to assess the functional efficiency of this nascent market we pay particular attention to the literature that is related to the academic debate over the chinese housing bubble issue the structure and operation of the housing market is another major concern in this paper finally we summarize the key insights of the literature that we surveyed note research gaps in the literature and discuss further research directions in this field

wage effects of labour migration with international capital mobility wage effects of immigration are investigated in a setting with international capital mobility which eliminates two thirds of the native wage effects of immigration without international capital mobility overall gains from migration in the immigration region are only a small fraction of total losses to native workers but with perfect international capital adjustment overall gains are larger than total losses to native workers two alternative tax policies to eliminate the negative wage effects of immigration on low skilled native workers are evaluated

fair allocation of indivisible goods and criteria of justice a set of n objects and an amount m of money is to be distributed among m people example the objects are tasks and the money is compensation from a fixed budget an elementary argument via constrained optimization shows that for m sufficiently large the set of efficient envy free allocations is nonempty and has a nice structure in particular various criteria of justice lead to unique best fair allocations that are well behaved with respect to changes of m this is in sharp contrast to the usual fair division theory with divisible goods

economic reform and interprovincial inequalities in china abstract this note is an attempt to explore two issues 1 the trend of interprovincial inequality in the post 1978 reform era in china and 2 the factors behind the dynamics of interprovincial inequality using recently released provincial gross domestic product gdp data we have shown that interprovincial inequality decreased in the fast half of the 1980s but started to increase in the second half of the 1980s to understand the impact of sectoral reforms on interprovincial inequality the overall inequality in provincial per capita gdp is decomposed into the contributions by the primary secondary and tertiary sectors it seems that the trend of interprovincial inequality has been largely induced by the reforms of the industrial sector which make up a large share of the secondary sector in addition national income data from the socialist national accounting system are used to identify the impact of interprovincial resource flows on interprovincial inequalities the findings seem to suggest a relative decline in the role of redistributive budgetary transfers
