co2 emissions of china s food industry an input output approach in a joint u s china statement on climate change the chinese government declared to peak co2 emissions around 2030 this demonstrates the government s determination to deal with carbon emission and climate change although the food industry is not a carbon emission intensive industry its large scale makes the emission reduction in the industry very important based on the input output structural decomposition method this paper calculates the co2 emissions of china s food industry from 1991 to 2012 and decomposes the change in co2 emissions of the industry during 1992 1997 1997 2002 2002 2007 and 2007 2010 into four main effects emission factor energy structure energy intensity and total output including four sub effects intermediate use domestic final demand import substitution and export extension the results show that changes in co2 emissions in the food industry mainly depends on total output effect and energy intensity effect energy intensity effect is the most important factor reducing co2 emissions as it reduced cumulative 213 million tons mt co2 emissions of the industry among total output effect the effects of intermediate use and domestic final demand are the two biggest contributors to carbon emissions finally we provide some policy advices for constraining and reducing co2 emissions of china s food industry the advices include increasing r d investment and the substitution of energy with other input factors to decrease energy intensity increasing the added value of the food industry optimizing the energy structure with more clean and low carbon energy and maintaining the prices of raw materials of the food industry i e agricultural products with taxes or subsidies

speculative investor behavior and learning as traders learn about the true distribution of some asset s dividends a speculative premium occurs as each trader anticipates the possibility of reselling the asset to another trader before complete learning has occurred small differences in prior beliefs lead to large speculative premiums during the learning process this phenomenon helps explain a paradox concerning the pricing of initial public offerings the result casts light on the significance of the common prior assumption in economic models

structural decomposition analysis of sources of decarbonizing economic development in china 1992 2006 abstract to analyze and understand decarbonizing economic development in china this paper undertakes a structural decomposition analysis of the historical change in energy related carbon intensity in china between 1992 and 2006 the results show that the energy related carbon intensity in china decreased by about three fourths between 1992 and 2006 and reduced carbon emissions by about two billion tons the decline in the energy related carbon intensity was mainly caused by changes in production pattern especially changes in energy intensity within each sector between 1992 and 2002 however the most important driving force of carbon intensity from 2002 2006 was not the energy intensity within each sector but the input mix on the other hand changes in demand pattern pushed up the carbon intensity to further decarbonize the economy in the future it is important for china to further enforce policies on shaping the production pattern such as reducing energy intensity and pay more attention to increasing the sustainability of the demand pattern at the same time

political structure taxes and trade abstract this paper examines the effects of the political organization of a chain of markets on the level of taxes and the volume of trade using a game theoretic approach we note that under certain demand stuructures noncooperative tax policies implemented by independent jurisdictions entail externalities detrimental to trade we show that the monoplization of the chain of markets or the implementation of cooperative tax strategies by internalizing the costs associated with these externalities increases the volume of trade and the tax revenues simultaneously

family welfare cultures strong intergenerational correlations in various types of welfare use have fuelled a long standing debate over whether welfare receipt in one generation causes welfare participation in the next generation some claim a causal relationship in welfare receipt across generations has created a culture in which welfare use reinforces itself through the family others argue the determinants of poverty or poor health are correlated across generations so that children s welfare participation is associated with but not caused by parental welfare receipt however there is little empirical evidence to sort out these claims in this paper we investigate the existence and importance of family welfare cultures in the context of norway s disability insurance di system to overcome the challenge of correlated unobservables across generations we take advantage of random assignment of judges to di applicants whose cases are initially denied some appeal judges are systematically more lenient which leads to random variation in the probability a parent will be allowed di using this exogenous variation we find strong evidence that welfare receipt in one generation causes welfare participation in the next generation when a parent is allowed di their adult child s participation over the next five years increases by 6 percentage points this effect grows over time rising to 12 percentage points after ten years while these findings are specific to our setting they serve to highlight that welfare reforms can have long lasting effects on program participation since any original effect on the current generation could be reinforced by changing the participation behavior of their children as well the detailed nature of our data allows us to compare the intergenerational transmission with spillover effects in other networks and to explore mechanisms our findings point to a special link between parents and their children with little impact due to close neighbors di participation we find suggestive evidence that what may change as a result of a parent being allowed di is their children s beliefs about the efficacy of trying to get on to the di program or their attitudes about di participation and its stigma

moderation in groups evidence from betting on ice break ups in alaska we use a large sample of guessed ice break up dates for the tanana river in alaska to study differences between outcomes of decisions made by individuals versus groups we estimate the distribution of guesses conditional on whether they were made by individual bettors or betting pools we document two major distinctions between the two sets of guesses 1 the distribution of guesses made by groups of bettors appears to conform more to the distribution of historical break up dates than the distribution of guesses made by individual bettors and 2 the distribution for groups has less mass in its tails and displays lower variability than the distribution for individuals we argue that these two pieces of evidence are consistent with the hypothesis that group decisions are more moderate either because groups have to reach a compromise when their members disagree or because individuals with extreme opinions are less likely to be part of a group

the uncommon insight of elinor ostrom author s bergstrom ted abstract this article was written in celebration of eleanor ostrom s nobel prize standard economic approaches to the problem of overuse of common property resources have emphasized two competing remedies the pigovian approach of corrective taxation and the property rights approach of internalizing externalities by means of assigning marketable property rights to individual owners with exclusive claim on the entire commons elinor ostrom pursues a third approach which is based on case studies of existing communities that have established successful and durable systems of managing common property resources this paper discusses her work and suggests that economists with an interest in public policy have much to gain from becoming familiar with the work of ostrom and her co authors

system dynamic modeling of energy savings in the us food industry abstract in the united states the food industry alone accounts for approximately 19 of the total energy consumed the objective of this study is to forecast the food related energy consumption and evaluate policy alternatives for reducing food related energy consumption in the medium and long term influential factors of energy consumption in the food industry include population growth rate gdp agriculture s share of gdp food waste technologies and agricultural investment based on the life cycle of the food industry five life stages were considered agricultural production industrial processing and packaging transportation wholesale and retail and household in this study based on the causal relationships and feedback loops between these factors and the energy consumed for each life stage a system dynamics sd model was designed to simulate the situation for the us food industry policy options of reducing waste percentage and improving industrial energy productivity are incorporated for building the energy use mitigation scenarios by implementing the integrated mitigation scenarios a 9 43 reduction in total food system energy consumption can be attained in 2030

change in energy related co2 carbon dioxide emissions in portuguese tourism a decomposition analysis from 2000 to 2008 abstract tourism is an activity with great potential in portugal at a time of economic crisis tourism is seen as an opportunity to boost the economy and provide sustainable economic growth this strategic path based on tourism has to be accomplished in order to make better use of the economic advantages but at the same time respecting the environment and environmental goals to which portugal is committed so it becomes important to analyze what effects contribute more to emissions in this sector as well as which tourism subsectors are more responsible for the increase of emissions the objective of this work is to identify the effects in which co2 carbon dioxide emissions in tourism can be broken down and analyzed as well as their evolution and which of them has more importance in determining emissions for that in this study a decomposition technique based on logarithmic mean divisia index was used in the 2000 2008 period for five tourism subsectors in portugal in general tourism activity is the most important effect energy mix carbon intensity and energy intensity effects also proved important

negotiated block trades and corporate control we identify negotiated trades of large percentage blocks of stock as corporate control transactions when a block trades and the firm is not fully acquired cumulative abnormal returns average 5 6 and 33 of the chief executives are replaced within a year stock price increases are larger when control passes to the new blockholder when management does not resist the blockholder s effort to influence corporate policy and when the block purchaser eventually fully acquires the firm these findings suggest that the specific skills and expertise of blockholders and not just the concentration of ownership are important determinants of firm value we examine 106 negotiated trades of at least 5 of the common stock of new york stock exchange nyse and american stock exchange amex listed corporations our primary objective is to assess the impact of these transactions on the firms whose shares are traded we also investigate the importance of active block investor s specific managerial expertise and incentives for firm value the emerging literature on concentrated ownership focuses on how the level of ownership affects a blockholder s incentives to undertake a variety of corporate decisions although it has been recognized that a blockholder s identity also can be important less attention has been paid to this issue several recent studies however provide evidence that blockholders incentives and expertise are not homogeneous for example holderness and sheehan 1985 find that the stock market reacts more favorably to initial block accumulations by six controversial investors who are often portrayed in the press as raiders than to initial accumulations by a random sample of investors morck shleifer and vishny 1988 find that firm value tends to be lower when the firm is run by a member of the founder s family than when it is run by an officer unrelated to the founder brickley lease and smith 1988 document that institutional blockholders are less willing to vote against management on antitakeover amendments when they are likely to have business dealings with the firm when a block trades the concentration of ownership typically does not change but the blockholder s identity does

a welfare criterion for models with distorted beliefs this paper proposes a welfare criterion for economies in which agents have heterogeneously distorted beliefs instead of taking a stand on whose belief is correct our criterion asserts an allocation to be belief neutral ine cient if it is ine cient under any convex combination of agents beliefs while this criterion gives an incomplete ranking of social allocations it can identify negative sum speculation in a broad range of prominent models with distorted beliefs

irreversible investment and knightian uncertainty when firms make a decision about irreversible investment they may not have complete confidence about their perceived probability measure describing future uncertainty they may think other probability measures perturbed from the original one are also possible such uncertainty characterized by not a single probability measure but a set of probability measures is called knightian uncertainty the effect of knightian uncertainty on the value of irreversible investment opportunity is shown to be drastically different from that of traditional uncertainty in the form of risk specifically an increase in knightian uncertainty decreases the value of investment opportunity while an increase in risk increases it

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

comparison of energy intensities in european union countries results of a structural decomposition analysis abstract this work proposes an input output structural decomposition analysis model to identify the sources of the differences in the energetic intensities of the european union countries given an economic structure a determined composition of the final demand and determined direct energy intensities by countries the work studies to what extent these factors explain the difference in aggregate energy intensities that are observed for different european union countries on the basis of this information indicators are constructed by sectors and countries that allow us to identify the role that each sector or country plays as an energy consumer the results show that the aggregate total energy differences in europe are strongly influenced by the direct energy intensity effect and by the demand effect without the different economic structures of the countries being an important factor in the explanation of these differences the metallurgical and manufacturing products sectors are identified as the most intensive in the aggregate energy intensity

do carbon taxes work analysis of government policies and enterprise strategies in equilibrium abstract to achieve the goal of carbon emission reduction a number of countries have implemented carbon tax policies and carbon pricing has become an important tool this paper discusses the interactions between a government and an enterprise for implementing carbon taxes over time or by level of tax considering greenhouse gas emission we examine the impacts of various carbon tax policies on enterprises investments in new technology their reductions in production quantity and governments tax remittances a case study of the strategic responses of three firms in taiwan s electronics cement and steel industries to two carbon emission policies promulgated by government shows that appropriate levels of tax can induce an enterprise to alter its production processes to achieve emission reduction as part of a long term business strategy

primary energy and greenhouse gases embodied in australian final consumption an input output analysis input output modeling of primary energy and greenhouse gas embodiments in goods and services is a useful technique for designing greenhouse gas abatement policies the present paper describes direct and indirect primary energy and greenhouse gas requirements for a given set of australian final consumption it considers sectoral disparities in energy prices capital formation and international trade flows and it accounts for embodiments in the gross national expenditure as well as the gross domestic product primary energy and greenhouse gas intensities in terms of mj and kg co2 e are reported as well as national balances of primary energy consumption and greenhouse gas emissions

input output analysis of co2 emissions embodied in trade and the driving forces processing and normal exports in recent years energy related co2 emissions embodied in international trade and the driving forces have been widely studied by researchers using the environmental input output framework most previous studies however do not differentiate different input structures in manufacturing processing exports and normal exports using china as an example this paper exemplifies how implications of results obtained using different export assumptions differ the study posits that the utilization of traditional i o model results in an overestimation of emissions embodied in processing exports and an underestimation in normal exports the estimate of co2 emissions embodied in china s exports drops by 32 when the extended i o model is used the choice of export assumption has more impact on the decomposition results for processing exports the study further highlights that for a country with an export structure similar to china it is meaningful to look into the impact of export assumption in embodied emission studies

strotz meets allais diminishing impatience and the certainty effect abstract decision makers tend to exhibit a higher degree of impatience when considering a delay to an immediate reward than when contemplating an identical delay to an equal future reward this work argues that diminishing impatience originates from the distinction between the certain present and the risky future a simple functional representation of preferences exhibiting time inconsistency when the future is uncertain is derived experimental evidence which is inconsistent with other formulations that account for diminishing impatience supports the proposed approach the new theory uncovers a tight relation between diminishing impatience and well known behavioral regularities in choice under risk and uncertainty jel d12 d81

financial intermediaries and liquidity creation trading losses associated with information asymmetries can be mitigated by designing securities which split the cash flows of underlying assets these securities which can arise endogenously have values that do not depend on the information known only to informed agents bank debt deposits is an example of this type of liquid security which protect relatively uninformed agents and we provide a rationale for deposit insurance in this content high grade corporate debt and government bonds are other examples implying that a money market mutual fund based payments system may be an alternative to one based on insured bank deposits

risk uncertainty and option exercise many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty motivated by experimental evidence such as the ellsberg paradox we follow knight 1921 and distinguish risk from uncertainty to capture this distinction we adopt the multiple priors utility model we show that the impact of ambiguity on the option exercise decision depends on the relative degrees of ambiguity about continuation payoffs and termination payoffs consequently ambiguity may accelerate or delay option exercise we apply our results to investment and exit problems and show that the myopic npv rule can be optimal for an agent having an extremely high degree of ambiguity aversion

highway robbery complementary monopoly and the hold up problem abstract we analyze the hold up problem in the context of the cournot ellet theory of complementary monopoly the strategic interaction among travelers and two distinct owners of successive segments of a segment road is used as a metaphor for complementary goods that are traded sequentially it is shown that when trade occurs double marginalization is eliminated furthermore allowing for strategic placement of the tollbooths simultaneous trade avoids the hold up problem but not double marginalization thus this analysis suggests the endogenous creation of institutions among complementary monopolistic suppliers that assure their customers of not being held up whenever it is strategically possible

the driving forces of china s energy use from 1992 to 2010 an empirical study of input output and structural decomposition analysis abstract the energy consumption in china has accelerated since the early 2000s and china became the largest energy consumer in the world by 2010 to examine the driving forces of china s energy use this paper conducts a structural decomposition analysis based on hybrid input output tables in addition we describe the framework of china s energy system by using two energy flow charts the results show that china s current energy use is investment led demand between 1992 and 2007 the three main final demand categories gross fixed capital formation household consumption and exports contributed approximately one third each to the changes of total energy use in china between 2007 and 2010 however three quarters of energy consumption changes came from investment activity only technological improvement saved approximately five percent of the total energy use annually during the periods of 1992 1997 1997 2002 and 2007 2010 in the period of 2002 2007 however its contribution dropped to only three percent p a due to the rise of the indirect energy requirement coefficient in the construction sector these results suggest that adjusting the final demand structure and improving energy efficiency further will meet china s energy challenges in the future

efficient and inefficient sales of corporate control this paper develops a framework for analyzing transactions that transfer a company s controlling block from an existing controller to a new controller this framework is used to compare the market rule which is followed in the united states with the equal opportunity rule which is used in many other countries the market rule is superior to the equal opportunity rule in facilitating efficient transfers of control but inferior to it in discouraging inefficient transfers conditions under which one of the two rules is overall superior are identified for example the market rule is superior if existing and new controllers draw their characteristics from the same distributions finally the rules effects on surplus division are analyzed and this examination reveals a rationale for mandatory rules

assessing co2 emissions in china s commercial sector determinants and reduction strategies abstract the commercial sector is one of the key sectors in china s economic transformation and carbon emissions control this paper applies var and stirpat models to investigate the major influencing factors of co 2 emissions in china s commercial sector over the period 1980 2014 according to the empirical results per capita gdp urbanization and energy structure have positive effects on co 2 emissions while energy intensity has negative effect on co 2 emissions in the long term besides per capita gdp ranks as the most important driving factors of co 2 in china s commercial sector followed by urbanization energy structure and energy intensity in that order this paper argues that reducing energy intensity and improving energy structure are the means to realize co 2 emission reductions in the commercial sector in the short and long term respectively besides this paper forecasts that co 2 emissions in china s commercial sector will be 1942 mt by 2030 which is huge and about half of the co 2 emissions of the european union in 2014 the findings have important implications for policy makers to enact co 2 emission reduction policies

calculation and decomposition of indirect carbon emissions from residential consumption in china based on the input output model abstract based on the input output model and the comparable price input output tables the current paper investigates the indirect carbon emissions from residential consumption in china in 1992 2005 and examines the impacts on the emissions using the structural decomposition method the results demonstrate that the rise of the residential consumption level played a dominant role in the growth of residential indirect emissions the persistent decline of the carbon emission intensity of industrial sectors presented a significant negative effect on the emissions the change in the intermediate demand of industrial sectors resulted in an overall positive effect except in the initial years the increase in population prompted the indirect emissions to a certain extent however population size is no longer the main reason for the growth of the emissions the change in the consumption structure showed a weak positive effect demonstrating the importance for china to control and slow down the increase in the emissions while in the process of optimizing the residential consumption structure the results imply that the means for restructuring the economy and improving efficiency rather than for lowering the consumption scale should be adopted by china to achieve the targets of energy conservation and emission reduction

blocks liquidity and corporate control the paper develops a simple model of corporate ownership structure in which costs and benefits of ownership concentration are analyzed the model cornpares the liquidity benefits obtained through dispersed corporate ownership with the benefits from efficient management control achieved by some degree of ownership concentration the paper reexamines the free rider problem in corporate control in the presence of liquidity trading derives predictions for the trade and pricing of blocks and provides criteria for the optimal choice of ownership structure the recent incomplete contracting approach in corporate finance has considerably improved our understanding of how small firms determine their capital structure the basic setting considered in this line of research is one where a founder manager seeks funding from one or several financiers the main premise is that the founder manager in her dealings with the financiers is primarily concerned with maintaining her private benefits of control for small firms these are often quite large relative to the financial returns thus for a small firm the problem of determining the financial structure often reduces to the problem of how to obtain fundingr while giving away as little control as possible to the financiers of course most financiers insist on some form of protection so that the final compromise reached in most financial contracts for small firms is one resembling a debt contract or a venture capital contract which protects the founder manager s control as long as the firm is performing adequately this perspective for small firms does not extend naturally to large firms because the private benefits of control of the managers for large firms are likely to be small relative to the firm s monetary returns so that protection of these benefits is not an overriding consideration moreover large firms

ownership concentration corporate control activity and firm value evidence from the death of inside blockholders we analyze how ownership concentration affects firm value and control of public companies by examining effects of deaths of inside blockholders we find shareholder wealth increases ownership concentration falls and extensive corporate control activity ensues share price responses are related to the deceased s equity stake control group holdings fall for two thirds of the firms due to either the estate s dispersal or inheritors selling stock a majority of firms become targets of control bids three quarters of bids are successful one third are hostile our evidence is broadly consistent with stulz s 1988 model of the relationship between ownership concentration and firm value the objective of this paper is to assess how changes in insider ownership concentration affect firm value corporate governance and the control of public companies we obtain our evidence on these issues by examining the effects of the death of an inside blockholder that is a member of the firm s control group as defined by securities and exchange commission sec disclosure rules who holds 5 percent or more of a firm s equity overall we find that the death of an inside blockholder an exogenous event is value enhancing reduces ownership concentration and leads to extensive corporate control activity our analysis has three components one we use market based evidence to evaluate how changes in ownership concentration affect firm value by analyzing the share price response to the death of an inside blockholder financial market efficiency implies that share prices capitalize gains or losses from changes in ownership concentration and future control events expected to ensue from an inside blockholder s death thus such valuation effects provide a test of the continuing controversy as to whether ownership concentration promotes managerial entrenchment or aligns insider and noninsider interests we find that the share price response to the death of an inside blockholder is significantly positive when the level of ownership concentra

china s energy consumption change from 1987 to 2007 a multi regional structural decomposition analysis abstract increasing use of energy has helped to stimulate china s economy despite central planning china has great differences in economic development energy endowment and energy consumption across its regions this paper uses the structural decomposition approach to uncover the regional disparities in energy consumption from 1987 to 2007 we also examine six possible key factors for the change in energy consumption by region we find that final demand change outpaced efficiency improvements to drive up energy use in all regions between 1987 and 2007 more surprisingly from 2002 to 2007 it appears that changes in production structure enhanced energy consumption in most regions china produced more energy intensive goods for capital investment and export we contend that improving the energy efficiency of key energy intensive sectors would lead a significant decline in energy intensity energy directly or indirectly is flowing from northwest central and north china to coastal regions regional specific policies should be designed to promote production structure change and curb energy demand

energy and carbon embodied in the international trade of brazil an input output approach abstract all goods and services produced in an economy are directly and or indirectly associated with energy use and according to the type of fuel utilized with co2 emissions as well international trade is an important factor in shaping the industrial structure of a country and consequently in affecting a country s energy use and co2 emissions this study applies input output techniques to the brazilian economy to evaluate the total impacts of international trade on its energy use and co2 emissions a commodity by industry io model in hybrid units energy commodities in physical units and non energy commodities in monetary units is applied to the brazilian economy in 1995 results show that total energy embodied in the exports of non energy goods of brazil equals 831 pj while total carbon embodied is 13 5 mtc these amounts are larger than the relevant amounts embodied in the imports of non energy goods respectively 679 pj and 9 9 mtc these figures are better understood by contrasting them with the total energy use and the corresponding total carbon emissions of the brazilian economy in 1995 estimated by this work 6781 pj and 99 4 mtc respectively this means that international inflows and outflows of energy embodied in non energy goods are in the order of 10 and 12 of the total energy use while inflows and outflows of carbon embodied in non energy goods are approximately 10 and 14 of the corresponding total carbon emissions of the brazilian economy in 1995 the general picture is that brazil is not only a net exporter of energy 153 pj and of carbon 3 6 mtc embodied in the non energy goods internationally traded by the country in 1995 but also that each dollar earned with exports embodied 40 more energy and 56 more carbon than each dollar spent on imports these findings suggest that brazilian policy makers should be concerned about the extra impacts international trade policy may have on energy use and carbon emissions of the country

ambiguity and the corporation group disagreement and underinvestment abstract we study a dynamic corporate investment problem where decisions have to be made collectively by a group of agents holding heterogeneous beliefs and adhering to a utilitarian governance mechanism in which each agent has a given influence in the decision in this setting we show that i group decisions are typically dynamically inconsistent ii dynamic inconsistency leads to inefficient underinvestment and iii the ability to trade securities among insiders or with outsiders may restore efficient investment decisions but it may in some cases lead to inefficient overinvestment our theory can help explain the empirical evidence on the effect of diversity of groups such as corporate boards on firms outcomes and more generally on the difference between group and individual behavior

an analysis of the stock price reaction to sudden executive deaths implications for the managerial labor market abstract certain characteristics of managerial employment arrangements and of the managerial labor market make shareholder wealth dependent on an executive s continued employment these wealth effects are investigated by examining the common stock price reaction to unexpected deaths of senior corporate executives abnormal stock price changes are documented for a sample of fifty three events these abnormal stock price changes are associated with the executive s status as a corporate founder and with measures of the executive s talents and decision making responsibility and of the transaction costs associated with renegotiating or terminating the employment agreement

carbon dioxide emissions in the u s economy a structural decomposition analysis this paper provides an empirical analysis of the impact of various influences on carbon dioxide emissions it incorporates methodological refinements of input output structural decomposition analysis which is the examination of economic change by means of a set of comparative static variations in key parameters of i o tables the analysis is performed using a two tiered klem model which allows for estimation of substitution and technological change effects within and between input aggregates the model is used to decompose the sources of change in co2 emissions in the u s over the 1972 82 timeframe using hybrid energy value tables for the initial and terminal years results show the significant effect of substitution within the energy sector and between energy and other inputs as the leading causes of the decline in carbon dioxide emissions

sources of change in industrial electricity use in the taiwan economy 1976 1986 abstract this paper applies an input output structural decomposition model in order to analyse the sources of change in the 1976 to 1986 electricity demands of the industrial sectors in taiwan various types of demand shifts technical substitutions and technological changes are identified the relative importance of 14 mutually exclusive sources of change is evaluated the results indicate that over the course of the study period while economic growth had the dominant impact on electricity use followed in importance by substitution effects effects due to technological change had an adverse effect being much weaker than those resulting from economic growth and substitution effects it is expected that this pattern will remain unchanged in the foreseeable future hence industrial electricity demand in taiwan will continue to grow

carbon dioxide emission drivers for a typical metropolis using input output structural decomposition analysis as the capital of china beijing is regarded as a major metropolis in the world study of the variation in temporal co2 emissions generated by the driving forces in beijing can provide guidance for policy decisions on co2 emissions mitigation in global metropolises based on input output structural decomposition analysis io sda we analysed the driving forces for the increment in co2 emissions in beijing from both production and final demand perspectives during 1997 2010 according to our results the co2 emission growth in beijing is driven mainly by production structure change and population growth partly offset by co2 emission intensity reduction as well as the decline in per capita final demand volume during the study period final demand structure change has a limited effect on the change in the co2 emissions in beijing from the final demand perspective urban trades urban residential consumption government consumption and fixed capital formation are mainly responsible for the booming emissions this study showed how the top down io sda methodology was implemented on a city scale policy implications from this study would be helpful for addressing co2 emissions mitigation in global capital cities and metropolises

analysis of interregional industry linkage and economic distance in china evidence from the mining industry abstractthe mining industry is an important sector of the national economy which provides essential support for energy and other resources for economic development industrial linkage and economic distance are two different concepts in measuring the correlationship of different industries in this article we apply the model that combines both of them to analyse the industries significantly influence the mining industry we find that electricity and heating industry and the mining industry itself from forward linkages have greatly influenced the mining industry and the industries from backward linkages affect mining industry are changing with industrial economic transformation we also find resources can flow across several regions only after 2007 which means the role of geographical factors limiting long range transportation of resources is weakening after 2007 and we explain how resources flow among various regions during 1997 2007 based on the findings above policy implications from the empiri
