migration under uncertainty about quality of locations abstract this paper develops a search theoretic framework for analyzing migration decisions of workers who can only observe the quality of a location by migrating to the location after accepting a job there after learning the location quality the worker can stay at the current job search locally at the same location or search for a job at another location leading to repeat migration this paper develops the properties of optimal search migration and repeat migration decisions and finds how revealed location quality influences the tradeoffs between local search and repeat migration the effects of search costs and better job opportunities on the reservation levels of wages and revealed quality levels are also determined

convergence in per capita carbon dioxide emissions among g7 countries a tar panel unit root approach the subject of this paper is the examination the convergence of per capita carbon dioxide emissions of the g7 countries during the 1960 2005 period in a nonlinear panel analysis framework in this approach first the linearity of the series was tested and when the linearity was rejected the threshold autoregressive tar panel unit root test which splits the data into two regimes was employed to examine the stationarity properties of the series because the null of linearity was rejected in the first step we tested the stationarity of the series using the tar panel unit root test in the tar panel unit root test we found that the united kingdom was the transition country whose per capita carbon dioxide co2 emissions determined the switch from one regime to the other the results showed that convergence existed in the first regime and divergence in the second when we tested whether absolute or conditional convergence existed we found that the per capita co2 emissions were conditionally converging in the first regime

intertemporal lifestyle changes and carbon emissions evidence from a china household survey abstract this paper examines the endogenous evolution of household consumption patterns and household carbon emissions hces by integrating the analysis methods of income distribution with climate change based on a large scale household survey spanning from 2012 to 2016 in china we estimated the direct and indirect hces observed inverse u shaped carbon kuznets curves ckc and significant changes in hces over the period at the household level applying the oaxaca blinder method we decomposed factors causing the changes in hces and found that income and demographic effects contribute only 25 1 to the total increase of hces the other 74 9 remain unexplained and we define them as the effect of intertemporal lifestyle changes further analysis from multiple perspectives illustrates that the lifestyles of households across various social strata are becoming increasingly higher carbon intensive over time even though the income remains unchanged the findings indicate that existing modeling and projections of carbon emissions based on income and household characteristics may underestimate the future emissions pressure from the household sector hence we conclude that in order to reach more meaningful results the increasing effect of lifestyles should be taken into account when conducting climate change studies and formulating climate policies

is there a leviathan in your neighborhood this paper measures effects of decentralization in local government hierarchies on local public sector size this sector shrinks if decentralization encourages competition among governments it expands if decentralization sacrifices scale economies in a sample of 3 022 counties larger county governments reduce competition and increase aggregate local public sector size relative to aggregate county income more cities and towns increase competition and reduce its size more special and school districts sacrifice scale economies and increase it two recent articles have attempted to identify the effects of decentralization in state and local government on the size of the state and local public sector wallace oates 1985 finds no important effects michael nelson 1987 finds modest evidence that increased competition among government units reduces the size of the public sector this article demonstrates that the effects of decentralization are important and complex decentralization which encourages competition reduces the size of the local public sector decentralization which discourages scale economies increases it

prices and qualities a search model recently there has been substantial interest in the study of price and or quality dispersion in markets with costly information many of these studies focus on the problem of price dispersion assuming that the quality is fixed i e homogeneous good the most distinct feature of these models is the way information is gathered information can either be obtained through the purchase of a newspaper at some cost information purchase models or through costly sequential or nonsequential search search models each of these models identifies the conditions under which a rational expectation price dispersion equilibrium will exist in particular using an information purchase model with two classes of consumers with differential information costs salop stiglitz 15 show that equilibrium may be characterized by a high and a low price for a homogeneous good on the other hand wildeschwartz 18 show that there can be price dispersion if consumers have different propensities to search they assume that one class of consumers will shop only once and the other class will shop an exogenously determined number of times before purchasing in their model only certain price distributions are sustainable in equilibrium the salop stiglitz and wilde schwartz results are due to the ex ante heterogeneity of consumer types in an interesting paper burdett judd 3 have established that price dispersion can exist even when consumers are identical due to ex post heterogeneity in information while the price dispersion models are illuminating in explaining the differential prices in the markets they are limited by their abstraction from the quality uncertainty goods of heterogeneous qualities can be and are offered in a recent paper 6 using an information purchase model with two classes of consumers we have analyzed the price and quality equilibria by examining three different environments involving costly information i quality information costly price information costless ii price information costly

sustainable consumption and production in the food supply chain a conceptual framework abstract increased globalization and a growing world population have a great impact on the sustainability of supply chains especially within the food industry the way food is produced processed transported and consumed has a great impact on whether sustainability is achieved throughout the whole food supply chain due to the complexity that persists in coordinating the members of food supply chain food wastage has increased over the past few years to achieve sustainable consumption and production scp food industry stakeholders need to be coordinated and to have their views reflected in an optimized manner however not much research has been done concerning the influence of stakeholders and supply chain members coordination in the food industry s scp context to facilitate the theory development for scp in this work a short literature review on sustainable supply chain management and sustainable supply chains in the food industry is provided to give the reader current knowledge on how the past and current research are introduced in this work following that different theories that drive sustainable consumption and production have been identified and focused as a result theories like the institutional theory dynamic capability theory and stakeholder theory are presented additionally a conceptual framework has been developed by identifying the indicators drivers and barriers based on the stakeholder theory to achieve the scp in food supply chain finally limitations and future scope are discussed

does gender inequality affect household green consumption behaviour in china abstract in this paper we examine whether gender inequality affects a household s decision to adopt green consumption behaviour in china building upon the literature that claims women tend to be more environmentally friendly than men we hypothesise that households in which women play a stronger role adopt greener consumption lifestyles based on a nationwide survey our empirical results show that households in counties with greater gender inequality use less energy efficient electric products and are less willing to save energy the results are robust to a number of variations in our empirical models social and economic factors are included to further explore the mechanisms underlying households decisions our findings provide new insights into green development from a micro level bottom up perspective they are relevant for policy makers because they indicate that promoting gender equality can have a favourable impact on green development

a case analysis of a sustainable food supply chain distribution system a multi objective approach abstract sustainable supply chain management is a topical area which is continuing to grow and evolve within supply chains downstream distribution from producers to customers plays a significant role in the environmental performance of production supply chains with consumer consciousness growing in the area of sustainable food supply food distribution needs to embrace and adapt to improve its environmental performance while still remaining economically competitive with a particular focus on the dairy industry a robust solution approach is presented for the design of a capacitated distribution network for a two layer supply chain involved in the distribution of milk in ireland in particular the green multi objective optimisation model minimises co2 emissions from transportation and total costs in the distribution chain these distribution channels are analysed to ensure the non dominated solutions are distributed along the pareto fronts a multi attribute decision making approach topsis has been used to rank the realistic feasible transportation routes resulting from the trade offs between total costs and co2 emissions the refined realistic solution space allows the decision makers to geographically locate the sustainable transportation routes in addition to geographical mapping the decision maker is also presented with a number of alternative analysed scenarios which forcibly open closed distribution routes to build resiliency into the solution approach in terms of model performance three separate ga based optimisers have been evaluated and reported upon in the case presented nsga ii was found to outperform its counterparts of moga ii and hybrid

energy consumption and co2 emissions convergence in european union member countries a tonneau des danaides abstract as the consumption of energy is responsible for approximately 80 of ghg in eu iea 2008 the impact of energy activity on the environment has received increasing attention over the last decades from scholars researchers politicians and society as a whole within eu member countries it is commonly accepted that the design of energy and mitigation policies either at national or at european level require a detailed and integrated investigation of convergence divergence pattern among the participating countries in this paper we examine the distribution dynamics of energy consumption and co2 emissions their intensities as well as the carbonization index in 23 european countries over a forty one year period in particular from 1970 to 2010 for this purpose we used quah s methodology which is based on the dynamics of cross section distributions the main conclusion is that for all the examined variables the hypothesis of convergence patterns for the eu sample is not valid moreover regarding each examined variable different groups of polarization established important differences occur across eu countries according to the climate type with respect to the examined variables our analysis provides strong evidence supporting the fact that national and european energy and mitigation policies should be implemented according to the non convergence paradigm the body of evidence provided by our analysis is of great importance to energy policy makers and for issues related to climate change

prioritizing sustainable electricity production technologies mcdm approach abstract economic technological social and political developments stressed the need for shifts in energy mix therefore it is important to provide a rationale for sustainable decision making in energy policy the aim of this paper is to develop the multi criteria decision support framework for choosing the most sustainable electricity production technologies given selection of sustainable energy sources involves many conflicting criteria multi criteria decision methods multimoora and topsis were employed for the analysis the indicator system covering different approaches of sustainability was established the analysis proved that the future energy policy should be oriented towards the sustainable energy technologies namely water and solar thermal ones it is the proposed multi criteria assessment framework that can constitute a basis for further sub regional optimization of sustainable energy policy

migration and income redistribution responsibilities this study examines whether afdc benefits determine or discourage state to state migration flows in the united states a pooled cross section time series model is developed to estimate afdc benefits in a state and recipients and whether benefits in one state affect benefits in other states a second model using data from the 1980 census and the panel study of income dynamics estimates migration of afdc recipients and the level of benefits in in migration and out migration states both models indicate that small but statistically significant amounts of migration occur which may be quite important but only in the long run movers although small in number are much more likely to move to a state with higher benefits states perceive this migration as important indicating that states should have less control and the federal government more control over income redistribution

testing for convergence in carbon dioxide emissions using a bayesian robust structural model we address international convergence in carbon dioxide emissions per capita and per value added derived from emission inventories based on production and consumption patterns we propose a bayesian structural model that accounts for heteroscedasticity and endogeneity between emissions and economic growth and tests for the existence of group specific convergence via shrinkage priors we find evidence for country specific conditional convergence in all emission inventories implying a half life of 2 7 3 1 years for production based emissions and 3 6 4 7 years for consumption based emissions when testing for global convergence without allowing for individual specific convergence paths the half life of hbox co 2 per capita increases to 15 26 years whereas emission intensities show a half life of 44 45 years our results highlight the current incompatibility between emission targets and economic growth and the need for faster diffusion of green technologies moreover there is no evidence for specific convergence dynamics in the european union the oecd or the countries that are subject to binding emission constraints specified in the kyoto protocol the institutional frameworks implemented in industrialized countries did not induce faster convergence among developed economies

energy and climate policy in china s twelfth five year plan a paradigm shift the twelfth five year plan fyp endorsed by the people s national congress in march 2011 plays a crucial role in shaping china s development trajectory over the next decades and especially for the fulfillment of the 40 45 carbon intensity reduction target by 2020 the plan will condition both the medium and long term perspectives of economic restructuring rebalance between the inclusive economic growth and environmental objectives which are compounded by multiple constraints faced by china such as aging population natural resources depletion energy supply security and environmental deterioration this article investigates the major energy and climate targets and actions specified in the 12th fyp to gain insights into the nature and magnitude of challenges and difficulties with regard to the medium and long run economic and environmental policies it points out that china should articulate sectoral policies with the global climate mitigation targets to avoid long term carbon lock in based on an in depth analysis of the objectives in the plan it is argued that the implementation should include mainstreaming developments of appropriate instruments to support cost effective energy efficiency improvements and carbon intensity reduction in the next five years

convergence of per capita co2 emissions across the globe insights via wavelet analysis abstract this paper examines the convergence of per capita carbon dioxide co2 emissions for 162 countries across the globe covering all income groups high income oecd high income non oecd middle income and low income countries as categorized by the world bank the incidence of stochastic convergence is analysed by making use of recently developed wavelet based unit root tests the existing studies on this subject make use of conventional unit root tests using time series and or panel data a serious drawback of these tests is that they analyse the stochastic behaviour of any series in time domain only whereas the stochastic process may behave differently across different frequencies as well thus wavelet methods are an obvious solution as they consider frequency dimension as well in addition to time dimension when analyzing the stochastic behaviour of any data series and hence these methods encompass the conventional unit root testing methodologies by providing a clear and complete picture of the stochastic process our empirical findings based on latest available time series annual data from 1960 to 2010 lend support in favor of convergence among 38 countries including 18 high income oecd countries 2 high income non oecd countries 13 middle income countries and 5 low income countries while for the rest of 124 countries the co2 emission series is found to be non stationary suggesting the divergence in these countries these findings are in contrast with the most of the existing studies which may be due to the use of wavelet based unit root tests that are of course better alternatives some policy implications evolve from the empirical findings

the impact of state economic differentials on household welfare and labor force behavior abstract this paper calculates state specific income expectations for low income households using a simultaneous model of household labor force and welfare participation decisions a variety of simulations indicate the interlocking effects of existing state differences in welfare wages and taxes on work welfare choices and income significant differences among similar households in different states occur equalization of welfare benefits eliminates some but not all of these differences but generates potentially serious policy problems for the states

employer search training and vacancy duration we develop a model of optimal employer search strategy when information about match quality is endogenous the model is tested using four data sets two of which have not previously been used as theory predicts we find that when filling positions requiring more training employers search more intensively and extensively employers also search more extensively when hiring workers with more education and with prior experience these findings provide strong evidence of systematic variation in search strategies based on the characteristics of the positions and job applicants factors that influence employer search also affect the duration of a vacancy

measuring the immeasurable a survey of sustainability indices sustainability indices for countries provide a one dimensional metric to valuate country specific information on the three dimensions of sustainable development economic environmental and social conditions at the policy level they suggest an unambiguous yardstick against which a country s development can be measured and even a cross country comparison can be performed this paper reviews the explanatory power of various sustainability indices applied in policy practice we show that these indices fail to fulfill fundamental scientific requirements making them rather useless if not misleading with respect to policy advice

geographical spread of global emissions within country inequalities are large and increasing abstract in spite of the extensive literature on greenhouse gas emission inequalities at the world wide level most of the evidence so far has been based on country level data however the within country dimension matters for both the implementation and the policy formation of climate policies as a preliminary step towards a better understanding of within country inequalities this paper measures their extent for the two major greenhouse gases co2 and ch4 over the 1970 2008 period using theil index decompositions we show that within country inequalities account for the bulk of global inequality and tend to increase over the sample period in contrast with diminishing between country inequalities including differences across sectors reveals that between sector inequalities matter more than between country inequalities and between sector inequalities become the dominant source of global inequality at the end of the sample period in the co2 case finally estimated social tensions arising from the disconnection between emissions and future damages turn out to be increasing as soon as within country disparities are taken into account these orders of magnitude should be kept in mind while discussing the efficiency and fairness of alternative paths in combating global warming

innovation and reputation this paper analyzes a monopolist that markets successive generations of new and improving nondurable products prices research intensity and product innovations are derived as sequential equilibrium outcomes to a dynamic game with incomplete information asymmetric information is an important feature of the model the monopolist is fully aware of the current product s quality as are consumers who have tried it however the beliefs of other people are characterized by a probability distribution that depends on the monopolist s marketing strategy and the product s popularity the analysis illustrates a new context in which price signaling might serve as a mechanism for ensuring that only high quality products are marketed more important it shows how product life cycles are generated in the absence of signaling and how a reputation for producing high quality goods becomes established in such cases

the influence of expert reviews on consumer demand for experience goods a case study of movie critics an inherent problem in measuring the influence of expert reviews on the demand for experience goods is that a correlation between good reviews and high demand may be spurious induced by an underlying correlation with unobservable quality signals using the timing of the reviews by two popular movie critics siskel and ebert relative to opening weekend box office revenue we apply a difference in differences approach to circumvent the problem of spurious correlation after purging the spurious correlation the measured influence effect is smaller though still detectable positive reviews have a particularly large influence on the demand for dramas and narrowly released movies

job search with belated information and wage signalling the paper uses multi armed bandit methods to characterize the optimal policy of the job search problem with belated information that is if the non pecuniary aspect of the job is discerned only after the job has been tested for one period there is given a sufficient condition such that the reservation wage property of the optimal search policy remains preserved even if a job searcher believes in a positive resp negative correlation between the wage rate pecuniary aspect and the job quality non pecuniary aspect offered by a firm

stochastic convergence in per capita co2 emissions an approach from nonlinear stationarity analysis abstract this paper studies stochastic convergence of per capita co 2 emissions in 28 oecd countries for the 1901 2009 period the analysis is carried out at two aggregation levels first for the whole set of countries joint analysis and then separately for developed and developing states group analysis a powerful time series methodology adapted to a nonlinear framework that allows for quadratic trends with possibly smooth transition between regimes is applied this approach provides more robust conclusions in convergence path analysis enabling a robust detection of the presence and if so the number of changes in the level and or slope of the trend of the series b inferences on stationarity of relative per capita co 2 emissions conditionally on the presence of breaks and smooth transitions between regimes and c estimation of change locations in the convergence paths finally as stochastic convergence is attained when both stationarity around a trend and convergence simultaneously hold the linear approach proposed by tomljanovich and vogelsang 2002 is extended in order to allow for more general quadratic models overall joint analysis finds some evidence of stochastic convergence in per capita co 2 emissions some dispersion in terms of convergence is detected by the group analysis particularly among developed countries this is in accordance with per capita gdp not being the sole determinant of convergence in emissions with factors like search for more efficient technologies fossil fuel substitution innovation and possibly industry outsourcing also having a crucial role

the effect of unemployment insurance on the riskiness of occupational choice abstract this paper examines the effect of unemployment insurance on the riskiness of occupational choice by postulating a model of job search in which job offers have two characteristics their wage and their security of tenure two versions are considered a general case in which the unemployment benefit is earnings related and a special case in which the benefit is of a flat rate form of particular interest in the paper is the individual s desired trade off between wage and security of tenure and how this trade off is affected by the type of insurance scheme in operation perhaps surprisingly we find that an earnings related scheme encourages risk taking behaviour by the poor and risk avoiding behaviour by the rich in contrast a flat rate scheme neither encourages nor discourages risk taking

information costs duration of search and turnover theory and applications this paper uses a formal model of search over multiattribute alternatives analyzed in a product market setting to investigate the theoretical foundations of the empirical literature on duration of search and turnover in product markets labor markets and marriage markets a number of specific empirical predictions are also derived in particular whether quality is a search attribute or an experience attribute is related to the cost of search the cost of inspection the price of the good and certain properties of the market distribution of price and quality

stochastic convergence in per capita co2 emissions evidence from emerging economies 1921 2014 abstract we employ the recently developed lm and rals lm unit root tests that allow for endogenously determined structural breaks to study stochastic convergence in relative per capita co2 emissions over the period 1921 to 2014 for a balanced panel of emerging market economies the results provide mixed evidence of the presence of stochastic convergence in particular stochastic convergence is achieved for eleven out of the seventeen countries under investigation this implies that the energy regulatory framework in these countries needs to be revaluated in order to reduce the carbon footprint to further comprehend the factors behind the observed disparities in emission stability we analyse the determinants of the identified groups an examination of the determinants of the observed behaviour in relative per capita co2 emissions reveal that income population financial development and trade are significant drivers with trade predominantly playing a larger role in emission growth also weak evidence is found in terms of a catching up effect in the growth of relative per capita co2 emissions

wages and job mobility of young workers this paper presents a discrete time version of jovanovic s model of worker firm matching descriptive evidence is presented that supports the notion that unobserved worker firm heterogeneity is an important component in the intertemporal structure of wages for young workers a structural econometric model of wage dynamics under worker firm sorting is developed and estimated finally a formal test of the matching model is carried out and the matching structure on intertemporal covariances of wages is not rejected my results indicate the necessity of jointly considering processes of turnover and wage growth when analyzing the labor market experiences of young workers

fragmentation and the growth of local government an assumption of the post world war ii metropolitan reform movement was that fragmentation of metropolitan regions into multiple local governments was wasteful and inefficient increasing the cost and size of government more recently polycentrists have argued that the competition between multiple governments in metropolitan regions can in factreduce the growth in government by providing a competitive check on the excessive demands of local bureaucrats for more resources in this article i explore the effects of fragmentation on growth in the size of suburban municipal government budgets and in the number of services offered competition inherent in more fragmented metropolitan regions is shown to slow the expansion in local government expenditures and service levels

economic competition and political competition an empirical note this paper has examined the proposition that more concentrated or consolidated metropolitan areas will produce public goods less efficiently than if there were a greater degree of interjurisdictional competition the empirical evidence garnered in section 3 suggests that interjurisdictional competition does tend to reduce the cost of providing local public services and consequently local government expenditure levels

examining green consumerism motivational drivers does premium price and demographics matter to green purchasing environmental deterioration caused by consumers non sustainable consumption pattern is putting a strain on the environment and is hindering sustainable development in order to impede this effect and promote a more sustainable economy one solution is to reduce or shift consumption from conventional products to green products the unfortunate reality indicates that inadequate information on how to promote consumers green behavioral intention is slowing the growth of green markets such inadequacy appears as a prevailing obstacle facing firms while developing segments and communicating strategies for effectively promoting green products the mentioned impact is more prevailing and most experienced in countries like malaysia hence consumers behavioral intentions must be better understood in order to strengthen knowledge about fostering green purchases this study aims to determine the motivational factors that influence green purchasing intention and simultaneously assess the moderator roles of the premium price and demographic characteristics given that consumers degree of greenness varies a survey was administered and a total of 405 usable questionnaires were obtained structural equation modeling sem was applied to test the hypotheses results indicate that environmental attitude eco label and cultural value man nature orientation significantly influence the green purchase intention the result also indicates that the premium price has no moderating effect denying its role as one of the main barriers for consumers to walk their talk as it has previously been reported by studies and opinion polls in addition the findings revealed that education level and gender have a significant positive moderation effect this suggests that green purchase intentions motivational factors are greater among highly educated individuals especially with female consumers in particular this study contributes to the understanding of the main factors that motivate consumers intention to purchase green products in malaysia it also offers insights and discusses implementations for manufacturers marketers and policy makers concerned with the drivers that motivate consumers green purchasing intentions which require different marketing plan and strategy than conventional products

economic growth sustainable development and food consumption evidence across different income groups of countries abstract considering that high population and income growths will lead the coming decades an increase in global food demand is expected livestock products such as meat are closely related to this trend but also associated with impacts on the environment and public health from land and water depletion to greenhouse gases emissions and higher risks of non communicable diseases this trend raises doubts about the sustainability of the food industry and thus a solution is needed for the problem how to feed the world population without compromising present and future generations the literature suggests that meat consumption should be reduced for the sake of the environment and global population however without considering the effects that such reduction would have on the economy inspired by these facts this paper empirically analyses the interactions between food consumption economic growth and sustainable development measured by the index of sustainable economic welfare more specifically the paper assesses the effect that food consumption has on the economy the econometric analysis applies the autoregressive distributed lag model for 77 countries further distinguished by their income group from 1995 to 2013 the findings support that meat consumption has different impacts on economic growth and sustainable development considering different income groups however there is an evident dilemma between economic growth and sustainable development since meat consumption has contradictory effects on each thus it is crucial to understand how to promote sustainability i e reducing the environmental externalities and chronic health diseases without compromising economic growth

globalization and the environment determinants of firm self regulation in china critics assert that globalization is detrimental to the environment because it encourages location of polluting industries in countries with low environmental regulations we suggest that globalization might also have positive environmental effects because global ties increase self regulation pressures on firms in low regulation countries using survey data from firms in china we find that multinational ownership multinational customers and exports to developed countries increase self regulation of environmental performance

systematic search belated information and the gittins index abstract this paper uses multi armed bandit methods to characterize the optimal solution of a rather complicated search problem the job search is conducted systematically and there is belated information that is some aspect of the job is discerned only after the job has been tested for one period

extensive search intensive search and hiring costs new evidence on employer hiring activity this paper presents recent evidence on employer search to fill a position a 1982 employer survey sponsored by the national institute of education and the national center for research in vocational education provides the basis for analyzing employer search and hiring costs the paper examines the effects of such factors as employer size dismissal costs unionization on the job training adjustment costs capital and labor market conditions on intensive employer search extensive employer search and hiring costs intensive employer search is measured by the average number of hours the employer spends recruiting screening and interviewing per applicant extensive search is measured by the number of applicants seen per applicant interviewed and the number interviewed per employment

convergence of carbon emissions at the household level in china a distribution dynamics approach abstract since household carbon emissions hces have become a new growing source and a significant contributor to global emissions the reduction of hces is crucial to formulate targeted and effective emission mitigation policies we need to fully understand the characteristics of the distribution and evolution of per capita hces and their urban rural and regional heterogeneity this paper explores the transitional dynamics of per capita hces in china by employing the distribution dynamics approach with panel data compiled at the household level we find that the overall per capita hces are unimodal distribution in the long run and the distribution dynamics of the per capita hces between the urban and rural areas or among the regional subgroups are quite different however the speed of convergence has accelerated over time moreover our findings indicate that the per capita hces in the urban areas will achieve convergence to an emission level much higher than that of the rural areas meantime the per capita hces in northeast china will converge to an emission level much higher than those of the other three regions these findings provide valuable insights for policymakers in implementing differentiated environmental policies for different regions and between urban and rural households in china

multiplicative structural decomposition analysis of aggregate embodied energy and emission intensities abstract aggregate intensity indicators such as the ratio of a country s energy and emissions to its gdp are often used by researchers and policymakers to study energy and environmental performance this paper analyzes the relationship between energy or emissions and value added or gdp from a different viewpoint namely from the demand rather than the production perspective using the input output i o framework the aggregate embodied intensity aei defined as the ratio of embodied energy or emissions to embodied value added can be defined at the aggregate final demand category and sectoral levels the total aggregate intensity can be presented as a weighted sum of the aeis at the final demand category or sectoral level changes of the aei at different levels can be decomposed to identify the driving forces using multiplicative sda a study using the latest 2007 and 2012 datasets of china indicates that a its aggregate intensity of co 2 emissions was mainly determined by the aei in investment and b the emission intensity effect generally contributed the most to the aei ratio changes at different levels the proposed framework can be applied to other aggregate intensity indicators and extended to multi country region analysis

are co2 emission levels converging among industrial countries time paths of carbon dioxide emissions intwenty one industrial countries are examinedfrom 1960 1997 to test for stochastic andconditional convergence both panel unit roottests and cross section regressions areperformed overall we find significantevidence that co2 emissions haveconverged

american federalism welfare policy and residential choices the relationship between welfare benefit levels and the residential choices of the poor raises two issues for federalism in the united states do state benefit levels affect the residential choices of the poor do residential choices of the poor affect the level at which a state sets its benefit levels empirical studies have seldom studied the interconnection between these two issues this research estimates simultaneously the mutual effects of welfare benefits and poverty rates while controlling for other economic and political variables when benefit levels become high the size of the poverty population increases conversely when poverty rates become high benefit levels are cut the findings are consistent with the claim that state determined benefit levels distort policy and residential choices

goodwill intertemporal price dependence and the repurchase decision stigler s i96i pioneering article on the economics of information directed economists attention to market situations where the classical assumption of perfect knowledge could not be supported his theory pictured a world in which prices were not known to the consumer a priori information being scarce was also costly but information had clear economic value to those wishing to possess it focus of the new theory thus came to be on an individual optimising over benefits expected price reductions and costs time spent canvassing to the activity of information gathering or search whilst this new direction taken by consumer theory has been towards greater descriptive realism the attendant drawbacks have been several technical complexities of formulation have commonly resulted in highly simplified models with utility linear in prices and purchase restricted to a single unit of the good even when time has been explicitly taken into account an invariable assumption has been the independence of prices from one period to the next 2 after twenty years stigler still remains alone in the literature as having made an attempt to integrate the idea of intertemporally correlated prices with the important economic concept of goodwill the present paper is an attempt to remedy within the context of a single model the above mentioned deficiencies the main emphasis of the paper as the title suggests is on the role of goodwill and intertemporal price dependence in the repurchase decision the decision whether or not to buy again at the same store or to look around the framework proposed is a dynamic one in which the consumer has in each period to a finite horizon an ex post and ex ante utility maximisation problem the ex post problem concerns her consumption decision in any period once prices are known the ex ante problem her decision as to how much

establishing the micro foundations of a macro theory information movers and the competitive local market for public goods e tiebout model of competition in the local market for public goods is an important and controversial theory the current debate revolves around the apparent disparity between macro 5 x empirical studies that show greater efficiency in the supply of public goods in polycentric regions compared to consolidated ones and micro evidence of widespread citizen consumer ignorance which has been used to argue that individual actions cannot plausibly lead to efficiency enhancing competition between local governments we argue that competitive markets can be driven by a subset of informed consumers who shop around between alternate suppliers and produce pressure for competitive outcomes from which all consumers benefit using data from a survey of overfive hundred households we analyze the role of these marginal citizen consumers and incorporate the costs of information gathering and the strategic interests of local governments into the competitive market model

convergence in co2 emissions a spatial economic analysis with cross country interactions abstract this research analyzes the evolution of co2 emissions per capita in a sample of 141 countries during the period 1970 2014 the study develops a spatially augmented green solow model by taking into consideration technological externalities and interdependence in the process of production which ultimately implies that co2 emissions in an economy are affected by the economic characteristics in neighboring countries the empirical model predicts convergence in co2 emissions among countries which is examined by means of modern dynamic spatial panel econometric techniques the multimodal distribution of the co2 emissions is consistent with the existence of three spatial clubs the space time dynamics of the three clubs are analyzed by means of the local directional moran scatterplot and spatial panel model with heterogeneous parameters our analysis reveals the hypothesis of spatial convergence clubs is more consistent with the data than the hypothesis of conditional convergence

income inequality and carbon dioxide emissions the case of chinese urban households abstract this paper draws on chinese survey data to investigate variations in carbon dioxide emissions across households with different income levels rich households generate more emissions per capita than poor households via both their direct energy consumption and their higher expenditure on goods and services that use energy as an intermediate input an econometric analysis confirms a positive relationship between emissions and income and establishes a slightly increasing marginal propensity to emit mpe over the relevant income range the redistribution of income from rich to poor households is therefore shown to reduce aggregate household emissions suggesting that the twin pursuits of reducing inequality and emissions can be achieved in tandem

a multidimensional measure of energy poverty in china and its impacts on health an empirical study based on the china family panel studies abstract inability or insufficient access to modern forms of energy is an important issue in development which makes the notion of energy poverty a widely discussed topic a consensus has been reached that energy poverty has serious health education and other socio economic impacts for people in a country however measurements of energy poverty have generally been absent or inaccurate especially for developing countries at the micro level this paper begins with the multidimensional nature of energy poverty and uses household level survey data in china to construct a quantitative measure of energy poverty covering both affordability of and accessibility to a broad range of forms of energy it then builds an econometric model to address empirically how much energy poverty affects health a statistically significant and robust negative impact on health from energy poverty is confirmed our results have important policy relevance in terms of understanding the current status quo of energy poverty in china and its consequences the concept can also be expanded to investigate similar issues in other developing countries

on employer specific information and internal labor markets the human capital literature of which becker s 2 paper is the seminal work stresses the productivity enhancing effects of schooling and on the job training later work by spence 21 and others emphasizes the fact that it is difficult for employers to ascertain the productivity of potential employees and suggests that activities such as schooling may provide employers with signals as to workers productivities in the signalling literature it is assumed that information generated concerning an individual s abilities is general in that it is known to all potential employers yet the information that an employer gathers concerning his workers abilities is not likely to be completely transferable to other employers as a consequence as rosen 18 249 points out there are limitations on the ability of the price system to achieve efficient assignments if the price system is incomplete there is a role for entrepreneurial activity of assembling an optimal work force this paper analyzes the employment relations that arise when employers information concerning new workers abilities is incomplete until after a period of employment the acquisition of such employer specific information is shown to lead to what has been referred to in the literature as internal labor markets internal labor markets as identified by dunlop 5 32 are the complex of rules which determine the movement of workers among job classifications within administrative units these movements may be transfers promotions demotions or layoffs to the exterior labor markets doeringer and piore 3 emphasize skill specificity and on the job training as the key factors in the emergence of the internal labor market along similar lines williamson wachter and harris 22 point out that job idiosyncracy can result in employment relations with attributes like those of internal labor markets by way of contrast this paper emphasizes the role of employer specific information in generating internal labor markets the theory provides an explanation as to why employers dismiss current employees at the same time that new employees are hired evidence that dismissal rates are not insignificant is presented in section iv the theory also provides a new rationale for long term em

an institutional theory perspective on sustainable practices across the dairy supply chain the need for sustainable practices in the food supply chain particularly in the area of energy reduction is becoming acute the food industry currently has to contend with multiple competing pressures alongside the new challenges of sustainable production we applied institutional theory to explore the role of supermarkets in the development of legitimate sustainable practices across the dairy supply chains the paper focuses on dairy supply chain organizations and their consumption of energy we conducted 70 semi structured telephone interviews with various stakeholders across the supply chain findings revealed that the majority of actors in the supply chain identified supermarkets as the dominant player and that the supermarkets exert pressure on other smaller organizations across the supply chain although some organizations wished to pursue a sustainable agenda through integrating new rules and legitimate practices within their own organization the dominant logic appeared to be one of cost reduction and profit maximization there was also evidence that supermarkets and other large organizations attempt to replicate publicly available information on green successes for image purposes we conclude that the dominant logic of cost reduction is so well established that challenging the dominant logic may prove difficult the challenge is therefore to complement the dominant logic with sustainable practices across the whole supply chain a role government needs to play this will require a broader more systemic approach to encouraging sustainable practices including investment and financing practices so that all members of the dairy supply chain can co operate and contribute to energy reduction

consumer search with uncertain product quality this paper presents a unified model of consumer search when both prices and qualities are uncertain it is assumed that price can be observed prior to purchase but that quality can be observed only after purchase and experience this two stage decision problem is of particular interest since in practice there is usually some connection between quality and price of the many interesting implications of this dependence explored in this paper is the result that the usual reservation price rule may no longer be optimal indeed the optimal stopping set may take one of several alternative and more realistic forms

a nonparametric analysis of income convergence across the us states abstract in this paper i apply the nonparametric methods proposed by quah to data on us state relative income levels in contrast to quah s results using cross country data i find no evidence of polarization in the cross state income distribution the long run density implied by the estimates is strongly unimodal this finding is consistent with the results of previous analyses of convergence in state income levels using other methods
