global educational expansion and socio economic development an assessment of findings from the social sciences summary among development agencies conventional wisdom holds that educational expansion improves economic welfare and health reduces inequalities and encourages democratic political systems we investigate the empirical foundations for these expectations in recent social science research consistent evidence indicates that health and demographic benefits result from educational expansion and suggests that education enhances but does not ensure individuals economic security however the impact of educational expansion on growth remains debated and decades of sociological studies offer evidence that educational expansion does not necessarily narrow social inequalities finally considerable controversy surrounds the implications of educational expansion for democratization reasonable forecasts of the consequences of further educational expansions need to consider the diverse social contexts in which these expansions will occur

employment and structural impacts of material efficiency strategies results from five case studies abstract in order to come up with a sound assessment of the effects of material efficiency innovations on growth employment and competitiveness different economic mechanisms have to be considered from a methodological point of view the analysis must be able to account for technology specific aspects the employment impacts of five innovations are analyzed plastic and paper recycling increased life span of automobiles car sharing and bio based products time horizons for all strategies are scenarios until 2020 the economic impacts are context specific with regard to innovation technology and country the economic impacts highlight substantial structural adjustments the overall economic net impact on employment tends to be neutral to positive stronger positive economic impacts result if first mover advantages can be established

the case of risk premia for risky jobs revisited abstract the empirical evidence concerning the existence of risk premia for risky jobs is contradictory some results support the existence of these premia while others do not this note provides a theoretical justification for these contradictory results in a fairly general model where firms and workers can effect the probability of a workplace accident

the effects of environmental fiscal reform in germany a simulation study this paper presents the first comprehensive model based impact analysis of the german environmental fiscal reform addressing the effects on co2 emissions economic growth employment and personal income distribution both an econometric input output model and a dynamic computable general equilibrium model are applied in order to enhance the credibility of our results the macroeconomic results are linked with a micro simulation model of the household sector so that detailed household data can be used to determine the effect of the environmental fiscal reform on personal income distribution we find a small double dividend in that energy consumption and co2 emissions decrease while employment rises the impact on economic growth is found to be minimal the fear that the environmental fiscal reform might interfere with the goals of social and income distribution policy is found to be largely unjustified

inflation unemployment and the median voter abstract we combine an econometric analysis of survey data on the relative seriousness of inflation and unemployment with the median voter theorem to derive the equilibrium rate of inflation if the natural rate of unemployment is 7 percent then the equilibrium inflation rate is 5 4 percent

china s uneven progress against poverty while the incidence of extreme poverty in china fell dramatically over 1980 2001 progress was uneven over time and across provinces rural areas accounted for the bulk of the gains to the poor though migration to urban areas helped the pattern of growth mattered rural economic growth was far more important to national poverty reduction than urban economic growth agriculture played a far more important role than the secondary or tertiary sources of gross domestic product gdp rising inequality within the rural sector greatly slowed poverty reduction provinces starting with relatively high inequality saw slower progress against poverty due both to lower growth and a lower growth elasticity of poverty reduction taxation of farmers and inflation hurt the poor external trade had little short term impact

endogenous technological change and emissions the case of the german steel industry abstract the paper starts from the observation that innovation and technical progress are only portrayed superficially in the predominant environmental economic top down models and that the assumption of perfect factor substitution does not correctly mirror actual production conditions in many energy intensive production sectors bottom up models on the other hand neglect macroeconomic interdependencies between the modelled sector and the general economy this paper presents a new modelling approach in an integrated bottom up top down approach based on the example of crude steel production in germany it is demonstrated how technological progress can be portrayed as process related and policy induced and how the technology choice between limitational processes can be explicitly modelled and implemented in the econometric input output model panta rhei the new modelling approach presented permits a process specific analysis of the impacts of changed frame conditions the effects of which on the choice of technology on the one hand and the technological progress on the other can be described endogenous to the model these features are demonstrated in a co2 tax simulation results show that policy induced technological change is besides a switch in production processes the major source of co2 reduction for the steel sector

the household responsibility system reform in china a peasant s institutional choice since 1978 the chinese government has implemented a series of major reforms including diversification of the rural economy production specialization crop selection in accordance with regional comparative advantage expansion of free markets and a marked rise in state procurement prices these reforms have brought about dramatic changes in china s rural areas however the most important change was the emergence and eventual prevalence of the household responsibility system hrs which restores the individual household and replaces the production team system as the unit of production and accounting in rural areas after the chaos of the cultural revolution china s moderate leaders started to reconsider china s rural policies although the government admitted that solving the labor management problems within production teams was the key to improving productivity and recommended measures to relate rewards to performance more closely the hrs was considered the reverse of the socialist principle of collective farming and was prohibited editorial board of china agriculture yearbook 1980 p 58 the official position at that time maintained that the production team was to remain the basic unit of production and accounting nevertheless toward the end of 1978 first secretly and later with the blessing of local authorities a small number of production teams in anhui province which was frequently victimized by flood and drought began to experiment with contracting land other resources and output quotas to individual households

an empirical analysis of dematerialisation application to metal policies in the netherlands abstract this paper presents a first empirical step in filling the gap between physical and economic models by combining a material flow model and an applied general equilibrium age model the goal of this paper is threefold firstly a new methodology is discussed for the integration of material and economic flow models secondly the new methodology is tested for its empirical applicability by simulation of material policies finally the analysis leads to the identification of major steps for filling the existing gap between physical and economic models further fiscal material policies are imposed to reduce the use of specific materials the material levy and the accompanying labour tax reduction shift the tax burden from labour to the use of materials the empirical illustration shows that the physical and economic flows can be made mutually compatible and that the combined model can be used for empirical analysis of material policies from this analysis of material policies in an economic model it may be concluded that the combination of an age model and a material flow model may produce an appropriate tool for analysing environmental sectoral and distributional effects of dematerialisation policies

material flows and economic models an analytical comparison of sfa lca and partial equilibrium models abstract the growing concern for environmental problems in the current economy has spurred the study of the way materials and substances flow through the economy resulting in many different types of analysis since all of these have their merits and shortcomings much of the present theoretical research seems to be focusing on combining the best aspects of each model type into an integrated model the aim of this paper is to make a first step in bridging the gap between the various types of analysis of material flows in the economy by discussing the main differences and similarities of three often employed model types substance flow analysis life cycle assessment and partial economic equilibrium analysis instead of submitting each model to a lengthy theoretical discussion we apply them to a single hypothetical example of a pollution problem by doing so we are able to evaluate the differences and similarities of the methods and results of the model in a practical way it appears that the results of the three models are complementary rather than contradictory each of them puts an emphasis on different aspects of the real world a sequential application of a number of limited models may therefore be an approach that provides more useful information than the tedious construction and application of an encompassing model that integrates these models

education s role in china s structural transformation abstract we explore education s role in improving the allocation of labor between china s agricultural and nonagricultural sectors and measure the portion of china s recent growth attributable to this channel using detailed micro level data and an empirical model that allows for the endogenous selection of education and sector of employment we estimate the relationship between an individual s educational attainment sector and income we find that about 11 of aggregate growth in output per worker from 1978 to 2004 is accounted for by increased education with 9 coming through the labor reallocation channel and 2 attributable to increased within sector human capital

returns to education a further international update and implications this paper updates evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 the new cross country evidence confirms and reinforces earlier patterns namely that returns are highest for primary education the general curricula the education of women and countries with the lowest per capita income the findings have important implications for directing future investment in education which for efficiency and equity purposes should concentrate on these priority areas

the impact of china s economic reforms on agricultural productivity growth this paper presents a method for assessing the relative importance of price increases and strengthened individual incentives due to the introduction of the responsibility system for the post 1978 increase in china s agricultural productivity data on post 1978 chinese agricultural performance suggest that a little over three quarters of the measured productivity increase is due to payment system changes and the remainder to price increases we also use our method to calculate incentive indices giving an estimate of the fraction of their marginal product that peasants received under the pre 1978 regime

the household responsibility system reform and the adoption of hybrid rice in china abstract this paper studies the diffusion of hybrid rice before and after the recent institutional change from the collective team system to the household based farming system in rural china a simple model which treats the adoption of hybrid rice as a portfolio selection problem is presented the model is tested against time series cross county data collected from hunan province in south china the empirical evidence suggests that 1 adoption behavior in the collective system was not consistent with the predictions of the theoretical model this evidence indicates the existence of administrative intervention in influencing production decisions in the collective system 2 there was a significant change in the structure of the adoption function following the transition from the collective system to the household based system and 3 adoption behavior in the household system is consistent with the predictions of the theoretical model

arrival of young talent the send down movement and rural education in china this paper estimates the effects on rural education of the send down movement during the cultural revolution when about 16 million urban youth were mandated to resettle in the countryside using a county level dataset compiled from local gazetteers and population censuses we show that greater exposure to the sent down youths significantly increased rural children s educational achievement this positive effect diminished after the urban youth left the countryside in the late 1970s but never disappeared rural children who interacted with the sent down youths were also more likely to pursue more skilled occupations marry later and have smaller families than those who did not

growth in china s grain production 1978 1997 a disaggregate analysis abstract this paper analyzes china s grain production during 1978 97 using disaggregate approach to explore disparities in growth patterns of respective crops the study reveals that during this period almost all the increased output can be attributed to the growth of rice wheat and corn the contribution of other crops as a whole was almost negligible the disparities in growth patterns were partly the result of crop adjustments induced by changes in food demand and dominated by substitutions of high yield crops for low yield crops in this process the adoption of new technologies played an important role varying opportunity costs of grain production in different areas also affected growth patterns of respective crops the trend in china s grain production in the past two decades suggests that the adherence to grain self sufficiency has become not only increasingly costly but also unnecessary

inflation unemployment choices in new zealand and the median voter theorem abstract using survey data we show that at any unemployment rate the new zealand median voter is much less averse to inflation than his counterpart in the united states this result is consistent with the median voter theorem

gender differentials in the payoff to schooling in rural china this article examines the gender differential in the payoff to schooling in rural china the analyses are based on a framework provided by the over education required education under education literature and the decomposition developed by chiswick and miller 2008 it shows that the payoff to correctly matched education in rural china is much higher for females than for males associated with this the wage penalty where workers are under qualified in their occupation is greater for females than for males over educated females however are advantaged compared with their male counterparts these findings are interpreted using the explanations offered for the gender differential in the payoff to schooling in the growing literature on earnings determination in china

rural reforms and agricultural growth in china this paper employs province level panel data to assess the contributions of decollectivization price adjustments and other reforms to china s agricultural growth in the reform period decollectivization is found to improve total factor productivity and to account for about half of the output growth during 1978 84 the adjustment in state procurement prices also contributed positively to output growth its impact came mainly from the responses in input use the effect of other market related reforms on productivity and output growth was very small reasons for slowdown in agricultural growth after 1984 are also analyzed copyright 1992 by american economic association

the development of the land lease market in rural china this paper examines the development of the land lease market in rural china special attention is paid to productive heterogeneity among farmers and the openness of the labor market in activating the land lease market a theoretical model is employed to explore the underlying connections an econometric model is implemented using a two period panel data set gathered in three counties of china s zhejiang province the results show that productive heterogeneity and a freer labor market do promote more land leases the implications for the institutional change literature are discussed

material efficiency and economic environmental sustainability results of simulations for germany with the model panta rhei abstract based on empirical evidence the paper discusses the impact of a consulting and information program for the improvement of material productivity with regard to economic and environmental targets for germany the instrument used in the analysis is the integrated economic environmental model panta rhei which is parameterized econometrically the paper presents the model and shows in a baseline forecast that without policy changes sustainability will be violated in both the economic and the environmental dimensions this applies to the latter particularly with regard to land use and material consumption the alternative simulation that introduces a consulting and information program for the improvement of material productivity yields a win win result growth rates of gdp and employment are rising the public debt is reduced and material consumption is much lower than in the baseline and remains at the actual level which means that a decoupling of growth and material consumption is possible

renewable energy and employment in germany abstract the positive impacts of an increasing share of renewable energy on the mitigation of climate change as well as on the decrease of the dependency of energy imports are indisputable however one persistent problem for the german economy has been its high level of unemployment in the recent past therefore any policy strategy will be measured also by its net impact on the labor market the paper describes the results of a study that models this impact and is novel within three respects firstly an input output vector for the renewable energy sector was developed based on the results of more than 1000 interviews with an extensive questionnaire secondly gross and net effect of two different policy scenarios for germany until 2030 were calculated and thirdly the approach varies from earlier studies by its explicit modeling of export and foreign trade effects

economy wide rebound effects for non energetic raw materials material efficiency is increasingly being seen as a means to save resources and achieve greater security of supply whether these aims can be achieved to the desired extent depends among other things on the presence of rebound effects this article estimates economy wide rebound effects for non energetic raw materials in the context of a set of material efficiency projects carried out in germany under the assumption that the efficiency technologies developed in these projects are scaled up to the national level input output analysis is used to calculate changed material requirements and corresponding rebound effects reduced material flows in monetary terms together with economic data are aggregated to an economy wide impulse which can cause re increases in the demand for the considered raw materials depending on the project specific framework conditions and subject to the modeling assumptions our estimates suggest that individual materials display a wide range of rebound effects ranging from close to zero to low double digit percentages these results point towards the conclusion that economy wide rebound effects do not make these efficiency measures obsolete however they also suggest that rebound effects should not be ignored in the assessment of the role of efficiency in future resource consumption

china s agriculture drivers of change and implications for china and the rest of world the overall goal of this article is to identify major changes in china s agriculture food economy and their implications for both china itself and more importantly to the rest of world china has become one of the fastest growing economies in the world since late 1970s gdp grew at about 10 annually in the past 30 years china s experience shows the importance of both domestic and external policies in achieving sustainable growth the results from this study provide significant policy implications to many countries that are currently china s major trade partners or those seeking greater economic and trade relations with china the main conclusions on the implications of china s rapid economic growth are that china s growth will provide more opportunities than challenges to the rest of the world on average overall the rest of the world will gain from china s economic expansion though this general conclusion may not hold for some countries

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

rural industry and labor market integration in eastern china abstract this paper tests the competitiveness of the labor market in a semi industrialized county located in eastern china labor market segmentation is linked to the degree of government interventions and the management structures of the local enterprises and two forms of rationing labeled entrance and time rationing are identified a test based on income maximizing behavior is developed to find the form of rationing that is consistent with the data the results show that the labor market is not competitive and time rationing prevails in the county in addition industrial wages are not responsive to experience and education but strongly biased against women and varying to government interventions

returns to education in china we were fortunate in having access to a survey of 800 adults in nanjing that was conducted by the international wool secretariate in 1986 the survey was intended for market research e g brand recognition but questions were asked about the respondent s age occupation income and education level these questions though not ideally worded were sufficient for the undertaking of a returns to education study we believe the data to be unique and of course the issue of interest is whether a member of the workforce in china faces investment decisions on education similar to those faced elsewhere the influence of sex and marital status on the level of income achieved by an individual was also examined the basic equation modeled personal income as a nonlinear function of schooling and experience but multicollinearity problems were encountered as a result a production function approach was successfully adapted to the returns toeducation model the collinearity problem was overcome and this approach allowed the ease of substitution of education for experience in income generation to be examined more formally an additional problem of errors in variables arose from a failing in questionnaire design and was handled statistically

economic impacts of higher oil and gas prices the role of international trade for germany the analysis concentrates on direct and indirect price increases induced shifts in international trade and structural changes in the oil importing economies the paper at hand asks whether a stabilizing effect via international trade and domestic structural change on the gdp of oil importing countries can be observed if a permanent oil price increase occurs at least for germany structural change from consumer goods to investment goods industry and an improvement of international competitiveness limit negative impacts of increased energy prices analysis is based on the extensive and disaggregated global ginfors model and the detailed inforge model for the german economy

control in a dynamic village economy the reforms and unbalanced development in china s rural economy abstract a dynamic control framework is used to model the chinese village economy in order to explain the rural sector s unbalanced growth in the post reform period village leaders are assumed to maximize a multi attribute utility function by manipulating local policy instruments subject to the structural relationships in the economy the model s parameters are estimated econometrically using a data set from forty villages in eastern china the empirical results identify important linkages between agriculture and rural industry in village economies unbalanced growth can partially be explained by the way economic incentives induce individuals in rural areas to move resources toward the rural industrial sector and away from agriculture

labor migration and returns to rural education in china this paper provides an answer to the following question why do empirical studies find low returns to schooling in rural china and yet the schooling rates are high i find that schooling played a significant role in raising the accessibility of urban formal employment to rural people in the late 1970s and early 1980s in the face of the government s restrictive policy on labor migration from rural to urban areas the large urban rural income difference provided a strong incentive for senior high school education the theory also explains the drop in the senior high school attendance in the mid 1980s

education and allocative efficiency household income growth during rural reforms in china this paper studies the contribution of schooling to rural income in china during factor market liberalization between 1986 and 1995 the relaxation of controls permitted farm households to reallocate productive inputs from agriculture to nonagricultural activities it is hypothesized that education facilitates this adjustment panel data from sichuan province suggest that schooling enhanced the ability of farmers to devote labor and capital to nonfarm production given the evidence that less than optimum levels of these inputs were allocated to nonagricultural uses during the transition the expansion of nonfarm activities contributed significantly to household income growth

bridging the gap between partial and total factor productivity measures using directional distance functions technical dependencies as well as data constraints limit our ability to allocate inputs across sectors and hence our ability to measure sectoral productivity we adapt a directional measure of efficiency to the measurement of sector specific productivity that does not require allocating all inputs across sectors applied to the agricultural sector of a group of countries the results show important differences in livestock and crops productivity growth commonly used partial factor productivity measures for livestock and crops tend to overestimate productivity growth in most developing countries while underestimating it in european countries

collective agricultural production a solution for transition economies abstract the paper examines theoretical reasons and provides examples for productivity differences between agricultural service cooperatives and collectives service cooperatives can utilize economies of scale enhance competitiveness and provide technical information advantages that often outweighed problems of free riding low investment and excessive political intervention agricultural collectives while not adding substantial advantages are in addition associated with problems of supervision and effort supply tendencies to substitute casual workers or mechanization for regular members and low investment incentives while collective forms of organization in transition economies respond to high risk and market imperfections they do so inefficiently policies that create conditions for service cooperatives to compete may lead to large productivity gains
