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

risk sharing in licensing abstract this paper studies the design of linear license contracts under demand or cost uncertainty the optimal contract consists in general of a mix of a fixed fee and royalties the source of uncertainty has a crucial impact on the type of royalties that must be used in particular under demand uncertainty at most two of the instruments are used the contract generally combines a fixed fee with an ad valorem royalty when cost is uncertain a wider variety of cases can arise the contract may involve a combination of either type of royalties coupled with a fixed fee alternatively it may be optimal to use all three available instruments

a structure decomposition analysis of china s production source co2 emission 1992 2002 this paper provides an empirical analysis of the relative impacts of various factors on co2 emissions from production of goods and services in china during two consecutive periods of 1992 1997 and 1997 2002 results show that on the positive side level of final demand for goods and services was the main reason for the increase of production source co2 emission while structure of net export has similar positive effect during the first period of 1992 1997 on the negative side technology factors remains as the main factors reducing emissions the level of net export played some role in the first period but the effects were seen in the second period from energy intensity fuel mix and input mix the results suggest that economic structure be focused as an important factor for co2 emission reduction with construction and transport as two key industries to lower carbon emission

coupling model of energy consumption with changes in environmental utility abstract this study explores the relationships between metropolis energy consumption and environmental utility changes by a proposed environmental utility of energy consumption euec model based on the dynamic equilibrium of input output economics theory it considers three simulation scenarios fixed technology technological innovation and green building effect it is applied to analyse hong kong in 1980 2007 continual increase in energy consumption with rapid economic growth degraded environmental utility first energy consumption at fixed technology was determined by economic outcome in 1990 it reached a critical balanced state when energy consumption was 22 109 kwh before 1990 x1 22 109 kwh expansion of energy consumption facilitated socio economic development but suppressed environmental benefits second technological innovation strongly influenced energy demand and improved environmental benefits the balanced state remained in 1999 when energy consumption reached 32 33 109 kwh technological innovation dampened energy consumption by 12 99 exceeding the fixed technology condition finally green buildings reduced energy consumption by an average of 17 5 in 1990 2007 they contributed significantly to energy saving and buffered temperature fluctuations between external and internal environment the case investigations verified the efficiency of the euec model which can effectively evaluate the interplay of energy consumption and environmental quality

variable returns to scale urban unemployment and welfare the proposition that free trade is superior to no trade has a classical ancestry adam smith and ricardo were amongst the first proponents of free trade samuelson 26 proved and it is held by economists today that free trade is the optimal policy in the presence of standard paretoconditions it is also generally agreed amongst economists that lower trade intervention is superior to higher trade intervention given competitive conditions in a small country these propositions do not hold however in the presence of factor market imperfections such as wage differentials in a small country and therefore production or wage subsidies improves social welfare the two models which are generally used to investigate the positive as well as normative aspects of trade theory in the presence of unemployment are the uniform real minimum wage model which is based on the assumption of general rigidity of real wage in one or two sectors of production and the sector specific minimum wage model which focuses on the phenomenon of rural urban migration in the face of large scale urban unemployment these two models are commonly utilized by trade theorists to analyze trade and unemployment specifically studies by haberler 13 johnson 16 batra and seth 3 findlay 12 and brecher 6 7 investigate the consequences of rigid factor prices for a small country whereas the normative as well as positive aspects of sector specific unemployment have been explored by harris and todaro 15 bhagwati and srinivasan 4 5 and more recently by batra and naqvi 2 das 10 and kahn 19 it has been correctly observed that the introduction of an exogenously specified real minimum wage among other things generates unorthodox results concerning unemployment and gains from trade a large body of research has also been concerned with the welfare implications of different commercial policies in the context of variable returns to scale kemp and negishi 20 have pointed out the beneficial effects of trade in the presence of variable returns to scale production subsidy and consumption taxes eaton and panagariya 11 have analyzed the question of gains from trade in the presence of variable returns to scale and in the context of pareto welfare criterion whereas choi and yu 8 have examined the welfare implications of tariffs and consumption taxes as well as the welfare rankings of these policies under variable returns to scale while panagariya and succar 25 have modified the necessary and sufficient conditions for stability under increasing returns to scale in urban sector

export share requirements and unemployment the case of quota trade restrictions such as import tariffs have been a common practice for protecting domestic import competing industries in most less developed countries ldcs foreign firms may however circumvent such protection through direct investment in the host countries this is the well known tariff jumping direct foreign investment which has been examined by brecher and diaz alejandro 7 they show that the foreign capital inflow leads to overproduction of the output of tariff protected sectors and hence results in welfare reduction recently rodrik 17 demonstrates that export share requirements when applied to the output produced by foreign capital may offset the negative effect of foreign direct investment through the contraction of tariffprotected overproduced sectors thus an increase in such a requirement may actually improve welfare this result contradicts the earlier finding of davidson matusz and kreinin 11 which is obtained from a partial equilibrium framework the existing literature on export share requirements remains deficient in two respects first the full employment models have been deployed ignoring the fact that most ldcs suffer from massive unemployment second the analysis has been confined by and large to tariff protection thereby neglecting quantitative trade restrictions e g import quotas it is noteworthy that it is quotas rather than tariffs which constitute a major constraint on imports by developing countries 2 the purpose of this paper is thus to remedy these two shortcomings by developing a sectorspecific unemployment general equilibrium model with quota restrictions on imports as noted by richardson 16 export performance requirements operate in a second best environment import

material implication of chile s economic growth combining material flow accounting mfa and structural decomposition analysis sda abstract over the last three decades the economic integration of the chilean economy into global markets has been taking place at a rapid pace for example in 1986 exports represented 29 of gdp while in 1996 they had increased to 38 of gdp this period of time was characterized by strong economic growth with an average annual growth rate of about 10 from a physical perspective material requirements more than doubled from 220 to 500 million tons of direct material inputs dmi during the same decade the rate of material growth requirements was around 13 per year the main objective of this study is to explain the changes in dmi by using a structural decomposition analysis sda the changes in material flow accounting mfa were broken down into the effects caused by changes in resource use per unit of output material intensity effect changes between and within sectors structural change effect changes in the composition of final demand mix effect changes due to shifting shares of domestic final demand and export categories category effect and finally changes in the overall level of economic activities level effects the results as a percentage of the total level of dmi used in 1986 indicate that economic growth was the major source of material changes 109 the material intensity and category effects explained 31 and 14 of the increase respectively the increase in the material intensity is mainly due to a declining quality of ores in copper production however these components were partly compensated by the structure 14 and mix 13 effects therefore for a southern american country such as chile the main causes of these changes in material consumption have been a combination of the nature of economic growth along with an increase in export production and material intensity of production

estimation and control of spanish energy related co2 emissions an input output approach this article uses input output methods to obtain the energy related co2 intensities for the spanish economy in 1992 based on those intensities it yields a structural decomposition of spanish energy related co2 emissions and an estimation of the price effects of several hypothetical carbon taxes levied on fossil fuel consumption these results are related to the ongoing discussion within eu circles and member states about the consequences of carbon energy taxes and to the simulated effects of such taxes in various countries the paper also responds to the lack of reliable disaggregated data on spanish co2 emissions and to the growing awareness on the limited effectiveness of spanish climate change policies

economic drivers of greenhouse gas emissions in china abstract for china greenhouse gas emissions increased by 0 075 gigatons gt in the period of 1995 2000 and increased by 4 23 gt from 2000 to 2009 then reached the amount of 8 61 gt in 2009 different from the traditional analysis focused on accounting sectors greenhouse gas emissions under the production based responsibility this paper investigates sectoral ghg emissions in china in the period of 1995 2009 from the perspective of consumption based and income based responsibility we found that different metrics yield very different ghg emission responsibilities the sector of electricity gas and water supply has the highest ghg emissions responsibility based on the production and income metrics while the sector of construction is the largest emitter under the consumption metric in the light of the key driver analysis of ghg emissions from 1995 to 2009 based on the consumption metric the change in the final demand volume is the largest driver of increase in china s consumption based ghg emissions 17 18 gt the changes in the production structure and the final demand structure are other contributors 0 53 gt 1 46 gt the improvement to the intensity of ghg emissions is the main force for ghg emissions mitigation 14 86 gt according to the income metric the contributions of input volume changes input structure changes and ghg intensity changes are similar to the effects of consumption based responsibility 19 11 gt 1 13 gt 14 95 gt the difference is that the change in the production structure is another force that offset ghg increase 0 98 gt results in this paper can give some recommendation on mitigating ghg emissions in china for policy makers from production side demand side and supply side

optimal incentives for income generation in universities the rule of thumb for the compton tax abstract in this paper we propose a novel framework to model one of the key links between universities and industry the undertaking of applied research we postulate that a basic objective of universities is to undertake fundamental research and that they receive public funding to do so nevertheless faced with tight budget constraints universities may have incentives to allow their staff to devote some of their time to income generating activities such as applied research or consultancy this opens up two channels by which universities can ease their budget constraint i by allowing academics to supplement their income universities may be able to hold down academic salaries ii universities can effectively tax the income that academics raise through applied research or consultancy for example through the imposition of overhead charges by easing their budget constraint universities may be able to take on sufficient extra staff to more than offset the time that existing staff are spending on non fundamental research and thus increase the amount of fundamental research that they can achieve with a given public budget we develop a model of this link between universities and firms and use it to determine the optimal tax that universities should impose on applied research income the compton tax used at mit in the 1930s is an early example of the use of this instrument

global primary energy use associated with production consumption and international trade presented in this study is a comprehensive analysis for energy use of different economic entities in global supply chains including the exploiter producer consumer intermediate trader and final trader the systems input output analysis method is adopted to trace the direct and indirect energy use associated with both intermediate production and final consumption activities in the economic system in the world economy 15 of the energy use embodied in trade turns out to be induced by final consumption and 85 is attributed to intermediate production different trading patterns for different economies are identified with the separation between energy trade for intermediate production and that for final consumption for japan with a production oriented trading pattern intermediate trade should be a top priority in local trade structure adjustment while final trade needs more attention for the government in the united states as the country is in a consumption oriented trade pattern this analysis aims to provide an in depth insight into energy sustainability as well as a sound scientific reference for policy making at the regional national and global scale

energy requirements of households in brazil abstract in this study we determine the total direct plus indirect energy requirements of a given set of brazilian households we use a generalized input output model in order to calculate the energy embodied in goods and services purchased by households of different income level in 11 capital cities of brazil our results show that on average the total energy intensity of household expenditure increases with income level although there is a considerable spread in energy intensities within income classes as well as disparities between regions of the country the total yearly average energy requirement per household in brazil in 1995 96 was 173 6 gj 61 of which was indirect with 32 8 gj for the lower income level 66 of which was indirect and 602 2 gj for the higher income level 62 of which was indirect of this total average energy requirement 76 was required for only three consumption categories utilities 31 mobility 28 and shelter 17 this analysis calls for the attention that has to be given not only to the direct energy consumption as motor fuels and electricity for example but also to the consumption categories that encompass an important part of the indirect energy requirement of households in capital cities in brazil

embodied energy use in china s industrial sectors abstract as the world s top energy consumer china is facing a great challenge to solve its energy supply issue in this paper energy use from all industrial sectors in china s economy of 2007 was explored by conducting an extended environmental input output analysis we compare the energy consumption embodied in the final demand for goods and services from 29 sectors with the energy demand required for the actual production process in each sector two different viewpoints for sectoral energy use have been presented energy use is directly allocated to the producer entity and energy use is reallocated to sector s supply chain from consumption perspective our results show that considerable amount of energy use is embodied in the supply chain especially for construction and other service activities sectors which is not detected if energy use is allocated on a production basis when further dividing embodied energy consumption into direct energy consumption and indirect energy consumption total indirect energy consumption is much higher than that of total direct energy consumption accounting for 80 6 of total embodied energy consumption in 2007 our results provide a more holistic picture on sectoral energy consumption and therefore can help decision makers make more appropriate policies

industrial co2 emissions from energy use in korea a structural decomposition analysis abstract this paper attempts to quantify energy consumption and co 2 emissions in the industrial sectors of korea the sources of the changes in co 2 emissions for the years 1990 2003 are investigated in terms of a total of eight factors through input output structural decomposition analysis changes in emission coefficient caused by shifts in energy intensity and carbon intensity changes in economic growth and structural changes in terms of shifts in domestic final demand exports imports of final and intermediate goods and production technology the results show that the rate of growth of industrial co 2 emissions has drastically decreased since the 1998 financial crisis in korea the effect on emission reductions due to changes in energy intensity and domestic final demand surged in the second period 1995 2000 while the impact of exports steeply rose in the third period 2000 2003 of all the individual factors economic growth accounted for the largest increase in co 2 emissions the results of this analysis can be used to infer the potential for emission reduction in korea

co2 emissions embodied in china us trade input output analysis based on the emergy dollar ratio to gain insight into changes in co2 emissions embodied in china us trade an input output analysis based on the emergy dollar ratio edr is used to estimate embodied co2 emissions a structural decomposition analysis sda is employed to analyze the driving factors for changes in co2 emissions embodied in china s exports to the us during 2002 2007 the results of the input output analysis show that net export of co2 emissions increased quickly from 2002 to 2005 but decreased from 2005 to 2007 these trends are due to a reduction in total co2 emission intensity a decrease in the exchange rate and small imports of embodied co2 emissions the results of the sda demonstrate that total export volume was the largest driving factor for the increase in embodied co2 emissions during 2002 2007 followed by intermediate input structure direct co2 emissions intensity had a negative effect on changes in embodied co2 emissions the results suggest that china should establish a framework for allocating emission responsibilities enhance energy efficiency and improve intermediate input structure

distributional incidence of green electricity price subsidies in china abstract distributional incidences are fundamental to environmental and energy policies a condition that has led to controversies on the equity of environmental and energy policy using data from china s urban household income and expenditure survey data from 2007 this study quantified the distributional effects of the green electricity price subsidy policy among chinese urban household and compared its effects by using lifetime income and annual income to classify households respectively the results show that total electricity subsidies are mainly driven by indirect electricity subsidies by using lifetime income to classify households subsidies to households in the poorest two groups accounted for less than 10 2 of the total subsidies whereas money distributed to households in the top two deciles reached 35 4 the comparison using annual income to group households also demonstrated the similar impact of the green electricity price subsidy policy china s future market reforms should allow electricity prices to reflect pollution abatement costs additionally a multi step block electricity price schedule can reduce the regressivity of the policy

what causes the change in energy demand in the economy the role of technological change this paper proposes a simple and theoretically clear approach to the estimation of technological change in a multisector general equilibrium framework this study employs the multiple calibration decomposition analysis mcda to evaluate technological change that is responsible for changes in energy use and carbon dioxide emissions in the japanese economy in the oil crises period from 1970 to 1985 the mcda serves as an elementary way of separating structural change due to technological change from that due to price substitution effects capturing the interdependence among economic sectors the empirical result provides a better understanding of the effects on the economy of technological change in that significant period

optimal trade policies for a small open economoy this paper investigates optimal trade policies for a small open economy with unemployment when factor prices are rigid random foreign prices result in random unemployment of resources the ranking of second best policies is investigated if the marginal propensity to consume the importable is positive and nonincreasing in income the optimal composite tariff dominates the optimal target price which in turn dominates the optimal quota copyright 1993 by the london school of economics and political science

energy embodied in the international trade of china an energy input output analysis abstract growing international trade has not only positively affected the people s republic of china s china s economic development but also expanded the exportation of energy embodied in goods during their production this energy flow out will pose risks to china s rational utilization of natural resources as well as environmental protection in this paper we evaluate the energy embodied in goods produced in china during 1992 2005 and use input output structural decomposition analysis to identify five key factors causing the changes of energy embodied in exports direct primary energy efficiency primary energy consumption structure structure of intermediate inputs structure of exports and scale of exports for the three sub periods of 1992 1997 1997 2002 and 2002 2005 results show that china is a net exporter of energy and the energy embodied in exports tends to increase over time the expanding total volume of exports and increasing exports of energy intensive goods tend to enlarge the energy embodied in exports within all three sub periods but these driving forces were offset by a considerable improvement of energy efficiency and changes in primary energy consumption structure from 1992 to 2002 and the effects of structure of intermediate input only in the sub period from 1992 to 1997 from 2002 to 2005 the sharp augmentation of energy embodied in exports was driven by all the five factors our research has practical implications for the chinese economy results of this study suggest that the energy embodied in trade should receive special attentions in energy policies design to limit the energy resource out flow and pollution generation

changes in energy requirements of the residential sector in india between 1993 94 and 2006 07 abstract a substantial amount of primary and secondary energy is consumed by the residential sector residential energy consumption includes energy required for construction activity and household consumption hence there is a need to quantify energy consumption its significance and causes calculating energy intensity of goods and services is the first step towards quantifying the causes this research is based on the 115 sector classification input output tables for india for 1993 94 1998 99 and 130 sector classification input output tables for 2003 04 and 2006 07 energy intensity of sectors related to household consumption has been calculated to analyze the trend between 1993 94 and 2006 07 indirect energy requirements of indian households have been assessed in this study from calculations of total primary energy intensity along with private final consumption expenditure results indicate that energy consumption has increased for all categories except medical care and hygiene percentage increase in indirect primary energy consumed by households is maximum for house building and recreation categories finally a complete decomposition analysis of indirect primary energy consumed by households has been carried out based on changing structural composition of the private final consumption expenditure energy intensity patterns per capita expenditures on energy and population

trade policies and welfare in a harris todaro economy in many developing countries rising unemployment is often attributed to increases in foreign imports triggered by declining foreign prices of imports to correct the chronic unemployment problem some developing countries chose an import substitution strategy by shutting off imports whereas others adopted an outward oriented policy by promoting exports north american free trade agreement nafta was favored by mexico but opposed by organized labor in this country because it was feared that nafta may increase unemployment in the u s which of these policies is more effective in reducing unemployment and raising domestic income protection has been ardently supported as a practical cure for unemployment in chile and argentina and many other ldcs in latin america similarly india adopted import substitution strategies behind high protection and a considerable bias against exports 1 the literature has also justified the use of tariffs for small countries under uncertainty and unemployment 10 9 but in general protection distorts the trade pattern and magnify the extent of the leontief paradox by limiting imports of capital intensive products into these developing countries that suffer from high labor unemployment 7 in the literature there have been two types of models that analyze trade problems in the presence of unemployment the generalized unemployment models have been developed by brecher 5 6 and batra and seth 3 2 in these models wage rigidity is ubiquitous and unemployment exists in all sectors and they are appropriate to analyze the impact of trade policies on unemployment in developed economies the harris todaro ht hereafter model 13 on the other hand assumes sector specific wage rigidity and permits unemployment only in the urban sector thus the ht model is appropriate for investigating the impacts of trade policies of ldcs that suffer

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

university entrepreneurship and professor privilege this article analyzes how institutional differences affect university entrepreneurship we focus on ownership of faculty inventions and compare two institutional regimes the united states and sweden in the united states the bayh dole act gives universities the right to own inventions from publicly funded research whereas in sweden the professor privilege gives the university faculty this right we develop a theoretical model and examine the effects of institutional differences on modes of commercialization entrepreneurship or licenses to established firms as well as on probabilities of successful commercialization we find that the us system is less conducive to entrepreneurship than the swedish system if established firms have some advantage over faculty startups and that on average the probability of successful commercialization is somewhat higher in the united states we also use the model to perform four policy experiments as suggested by recent policy debates in both countries copyright 2013 the author 2013 published by oxford university press on behalf of associazione icc oxford university press

energy requirements of sydney households supporting the lifestyles of the populations of modern cities requires vast quantities of natural resources and leads to environmental stresses such as air and water pollution research into the metabolism of cities therefore aims at understanding the physical flows into within and out of cities with a view to reducing the use of resources and the environmental impacts one important physical indicator is energy use most studies on cities only consider direct or end user energy consumption since the function of cities is to serve the lives of their residents indirect energy use in cities or energy embodied in the consumption of goods and services by its residents can be regarded as being as important as direct energy use however physical models of cities are extremely complex and have difficulty in dealing with boundary issues and hence the indirect resource requirements in this paper we use input output analysis and detailed household expenditure data to yield comprehensive energy use breakdowns for the 14 statistical subdivisions of sydney multivariate regression and structural path analysis spa are used to interpret the results clear correlations can be drawn between energy use and income household size age and degree of urbanity the structural path analysis is used to demonstrate how significant differences in lifestyles between inner and outer areas of sydney leads to different energy use characteristics this final consumption based approach to analysing the energy requirements for households has important implications for measures aimed at reducing energy use which tend to only consider direct energy use d 2004 elsevier b v all rights reserved

inventor moral hazard in university licensing the role of contracts abstract we examine commonly observed forms of payment such as milestones royalties or consulting contracts as ways of engaging inventors in the development of licensed inventions our theoretical model shows that when milestones are feasible royalties are not optimal unless the licensing firm is risk averse the model also predicts the use of consulting contracts which improve the firm s ability to monitor inventor effort because these contracts increase the firm s expected profits the upfront fee that the university can charge is higher than otherwise these results therefore support the commonly observed university policy of allowing faculty to consult with licensing firms outside of their university contracts they also support firm policies of including milestones an empirical analysis based on a survey of 112 businesses that license in university inventions supports the complementarity of milestones and consulting suggested by the theory

impacts of a rise in electricity tariff on prices of other products in vietnam abstract this study examines the impacts of increasing electricity tariff to the long run marginal cost on prices of other products using a static input output approach it is found that such an increase would drive up the prices of all other products although the aggregate price impact from such an increase is not large it would be socially difficult to implement this increase at one time particularly given that vietnam is facing high inflation rate a roadmap for electricity tariff increase is thus discussed

imperfect labor mobility and unemployment in ldcs in the two sector two factor general equilibrium literature generic unemployment has been introduced under the assumption of decreasing returns to scale in production see e g batra and seth 1 295 306 and yu 10 399 404 whereas sector specific unemployment has been introduced under the assumption of sticky wages e g harris and todaro 6 136 42 corden and findlay 5 59 78 khan 8 527 47 and marjit 9 527 47 in either case however labor is assumed to be perfectly mobile between two sectors the latter assumption has recently been a major topic of further research in the two sector general equilibrium literature specifically it is argued that in a perfectly competitive environment despite significant intersectoral wage differential caused by various parametric policy changes enough labor do not move from the low wage to the high wage sector to equate the wage rates in two sectors even in the long run locational preferences attachment to existing arrangements and also the high costs of relocation are usually cited as the possible reasons behind the sluggish movement of labor from one sector to the other casas 2 747 61 in a pioneering article has modeled this phenomenon of general immobility of labor in a standard two sector model of production in his model however casas assumes full employment of labor the purpose of the present paper is to extend the casas model further by incorporating unemployment caused by sector specific sticky wages of the harris todaro variety and examine the effects of growth and trade policies on output employment and welfare of a small country we will highlight the role of the elasticity of labor mobility parameter in our main results and demonstrate that there exists a critical minimum value of the elasticity of labor mobility parameter that will ensure the validity of the conventional results even in the world of imperfect labor mobility several interesting results emerge from our analysis in particular we have shown that capital accumulation causes urban unemployment to rise and the optimal tariff for a small open economy is positive the paper is organized as follows in section ii we lay out the basic model of labor immobility and unemployment and in section iii we derive the basic comparative static results in

a quantile approach to assess the effectiveness of the subsidy policy for energy efficient home appliances evidence from rizhao china abstract a one year subsidy program for energy efficient home appliances has been implemented in china we construct a dataset consisting of participant and non participant households in both urban and rural areas of rizhao city by applying a quantile regression and counterfactual analysis this study disentangles the impact of this subsidy program and inherent household attributes on per capita residential electricity consumption first contrary to the mean regression the elasticity of electricity consumption to household s income age education and energy saving awareness varies markedly across the electricity consumption distribution and shows discrepancy between urban and rural areas second while inherent household attributes are identified as a primary determinant to the changes in residential electricity consumption the effect induced by the subsidy incentive is more significant at the middle of the electricity consumption distribution than at the tails third there are significant rebound effects that lead to overall increase in household electricity consumption our results suggest that the disparity between urban and rural regions and targeted consumer behavior changes should be taken into account to ensure the effectiveness of a future energy efficient subsidy program

does government funding complement or substitute private research funding to universities abstract there is growing political pressure on universities to intensify their interaction with industry and to enlarge their own research funding options in a context characterised by increasing constraints on public spending however whether the successful achievement of such a political desired outcome is consistent with a restriction of government funding is not clear and requires further investigation as a matter of fact there is scant empirical evidence on whether and to what extent government funding affects the external funding options available to universities in particular those related to research and consulting activities by using a set of probit and tobit panel data models estimated on financial data for the whole population of italian university departments engaged in research in the engineering and physical sciences this paper provides evidence that government funding to universities complements funding from research contracts and consulting contributing to increasing universities collaboration with industry and activating knowledge transfer processes

an analysis of co2 emissions of japanese industries during the period between 1985 and 1995 this paper examines the factors that have an effect on co2 emissions produced by japanese industries between 1985 and 1995 by using input output tables the effects of environmental technological changes etc and production technological changes ptc on co2 emissions are considered separately furthermore backward and forward linkage effects in each sector that shows the extent to which each sector spreads or receives co2 emissions impacts across all of sectors will be calculated the results show that both types of technologies contributed to a decrease in co2 emissions during the bubble economy of the late 1980s but not during the recession of the early 1990s trade factors succeeded in decreasing co2 emissions in both periods thus trade structures facilitated the turning of japan into a net importer of co2 emissions between 1985 and 1995 the backward and forward linkage effects also decreased during the boom of the late in 1980s but not the recession of the early 1990s while the chemical products and electrical machinery sectors continued to reduce both effects this indicates that both sectors were relatively successful in decreasing their co2 emissions impacts between 1985 and 1995

evaluating the relationships among economic growth energy consumption air emissions and air environmental protection investment in china abstract this paper analyzed the interactions among china s economic growth and its energy consumption air emissions and air environmental protection investment during 2000 2007 conventional energy and emergy are applied to quantify energy consumption and emissions impact respectively the five indicators based on money energy and emergy including ratio of nonrenewable energy to renewable energy rnr energy use per unit gdp eupg environmental cost per unit gdp ecpg impact of emissions per unit energy consumption iepec and environmental benefit per unit environmental protection investment ebpei are presented to depict the relationships among economic growth and energy consumption and impact of air emissions and air environmental protection investment the results show that energy consumption rapidly rises with china s fast economic growth however energy efficiency and environmental loading intensity from energy consumption are reduced simultaneously but their improvements fall far behind economic growth rate impact of air emissions mainly composed of impact of emissions on human health especially dust is slightly decreased the performance of air environmental protection investment is obviously declined in the study period generally speaking the conflict among economy energy and air environment protection is slightly mitigated but still acute due to great dependence of china s economy on fossil energy and inefficient environmental protection measures finally this paper discusses the corresponding issues and then puts forward some related suggestions

distributional impacts of climate change mitigation in indian electricity the influence of governance abstract studies that examine the distributional impacts of climate change mitigation policies often neglect the influence of institutions that implement these policies this study examines the short term consumption side distributional impacts of expanding low carbon electric supply in the state of maharashtra india with a focus on the influence of regulatory discretion in pricing households welfare impacts from economy wide electricity price shocks are simulated against a baseline that is calibrated to actual household economic and electricity service conditions including actual electricity budgets block tier prices and supply rationing industrial price impacts are propagated to households using a leontief input output analysis regulatory pricing decisions are evaluated based on social welfare metrics for economic efficiency and income inequality the analysis reveals new linkages between climate change mitigation electricity policy and income distribution low income households can be shielded from mitigation impacts without losses in aggregate welfare to the extent that regulators can recover mitigation costs through industrial price increases regulators flexibility to distribute costs across households is constrained by industrial customers migration off the grid reduced supply interruptions to the rural poor from the resulting demand contraction are a potential co benefit of mitigation distributional impacts therefore depend on other electricity policies that are driven by the political economy of the sector

input output analysis of alternative policies implemented on the energy activities an application for catalonia abstract the aim of this paper is to analyze the economic impact of alternative policies implemented on the energy activities of the catalan production system specifically we analyze the effects of a tax on intermediate energy uses a reduction in intermediate energy demand and a tax on intermediate uses combined with a reduction in intermediate energy demand the methodology involves two versions of the input output price model a competitive price formulation and a mark up price formulation the input output price framework will make it possible to evaluate how the alternative measures modify production prices consumption prices private real income and intermediate energy uses the empirical application is for the catalan economy and uses economic data for the year 2001 the combination of a tax on energy uses and an improvement in the energy efficiency of the production system is a measure that accomplishes both economic and environmental goals since it has no effects on prices it has a positive effect on private real income and finally energy consumption is considerably reduced

the structure of licensing contracts industrial organization theory has explored several issues related to licensing but empirical analyses are extremely rare we amass a new and detailed dataset on licensing contracts and use it to present some simple facts concerning licensing behavior our analysis reveals robust cross industries differences in several contractual features such as exclusivity cross licensing ex ante versus ex post technology transfers and licensing to related versus unrelated parties we offer an interpretation of these facts based on cross industry variation in the strength of intellectual property rights

the role of equity royalty and fixed fees in technology licensing to university spin offs we develop a model based on asymmetric information adverse selection that provides a rational explanation for the persistent use of royalties alongside equity in university technology transfer the model shows how royalties through their value destroying distortions can act as a screening tool that allows a less informed principal such as the university s technology transfer office tto to elicit private information from the more informed spin off we also show that equity royalty contracts outperform fixed fee royalty contracts because they cause fewer value destroying distortions furthermore we show that our main result is robust to problems of moral hazard beside the coexistence result the model also offers explanations for the empirical findings that equity generates higher returns than royalty and that ttos willing to take equity in lieu of fixed fees are more successful in creating spin offs this paper was accepted by david hsu entrepreneurship and innovation

the role of consumption patterns demand and technological factors on the recent evolution of co2 emissions in a group of advanced economies changes in production structures and modifications of patterns of consumption are key factors in the fight against environmental harm initiatives such as agenda 21 promoted by the un highlight the need to evaluate the relationships among factors of production and consumption innovation and demographics and the environment in the attainment of sustainable development in this context our work studies in depth those factors underlying the economic activity of households in a representative group of european union countries and the us within the framework of an input output model a structural decomposition analysis is considered in order to identify the weight that growth in demand changes in patterns of consumption changes in the distribution of income the substitution of inputs and changes in energy intensity have all had on the evolution of co2 emissions the work specifically seeks to identify common patterns and differential behaviors among productive sectors in the european social environment the results show that growth in demand and therefore in production largely absorbs the limited effect of technological and efficiency improvements and the incipient changes observed in consumption patterns

a structural decomposition analysis of the emissions embodied in trade abstract the aim of this study is to quantify the driving forces behind the growth of carbon dioxide emissions embodied in trade eet the world input output database is used to estimate eet in 40 countries during 1995 2007 after which a structural decomposition analysis is applied to avoid biases in the results we have used the input output tables in previous year s prices and chained the outcomes in many developed countries the growth of emissions embodied in imports is much higher than the growth of emissions embodied in exports a key reason for this finding is the change in the structure of trade both in intermediate and in final products emerging economies like the bric countries have increased their share in production and trade at the expense of developed countries producers and consumers in developed countries have shifted towards importing a larger share of products from emerging countries this is the distinguishing feature that led to an increase of emissions embodied in imports for developed countries and an increase of emissions embodied in exports for emerging countries these results suggest policy makers to monitor eet more carefully and take the effects of trade on emissions into consideration

the impacts of china s household consumption expenditure patterns on energy demand and carbon emissions towards 2050 abstract this paper explores how china s household consumption patterns over the period 2005 2050 influence the total energy demand and carbon dioxide co2 emissions in two baseline scenarios and how it influences carbon prices as well as the economic cost in the corresponding carbon mitigation scenarios to this end we first put forward two possible household consumption expenditure patterns up to 2050 using the working leser model taking into account total expenditure increase and urbanization for comparison both expenditure patterns are then incorporated in a hybrid recursive dynamic computable general equilibrium model the results reveal that as income level increases in the coming decades the direct and indirect household energy requirements and co2 emissions would rise drastically when household expenditure shifts from material products and transport to service oriented goods around 21 000 mtce 1 of primary energy and 45 billion tons of co2 emissions would be saved over the 45 year period from 2005 to 2050 moreover carbon prices in the dematerialized mitigation scenario would fall by 13 in 2050 thus reducing the economic cost

co2 emissions from household consumption in india between 1993 94 and 2006 07 a decomposition analysis abstract co 2 emission from anthropogenic activities is one of the major causes of global warming india being an agriculture dependent country global warming would mean monsoon instability and consequent food scarcity natural disasters and economic concerns however with proper policy interventions co 2 emissions can be controlled input output analysis has been used to estimate direct and indirect co 2 emissions by households for 1993 94 1998 99 2003 04 and 2006 07 complete decomposition analysis of the changes in co 2 emissions between 1993 94 and 2006 07 has been done to identify the causes into pollution energy intensity structure activity and population effects according to broad household consumption categories results indicate that activity structure and population effects are the main causes of increase in co 2 emission from household fuel consumption to identify the causes at the sectoral level a second decomposition has been done for changes between 2003 04 and 2006 07 to identify the causes in the next stage finally alternative energy policy options have been examined for each consumption category to reduce emissions combined strategies of technology upgradation fuel switching and market management in order to reduce co 2 emissions for sectors like batteries other non electrical machinery construction and electronic equipments including television for which all the effects are positive need to be adopted

technological gap scale economy and china s industrial energy demand abstract the industrial sector in china is energy intensive and accounts for more than 60 of the nation s total energy consumption demand narrating the story behind the growth of china s industrial energy consumption could help us understand the past and prepare for the future this paper aims to investigate the factors affecting china s industrial energy consumption in the 21st century by using an extended production theoretical decomposition approach pda with considering the technological gap and scale of the economy effects the new proposed decomposition framework includes four new factors namely the energy technological gap the output technological gap energy scale efficiency and output scale efficiency the results show that in the 21st century the energy consumption of china s industry increased by more than one billion tons of standard coal the expansion of the industrial economy is a dominant driver of china s industrial energy consumption while potential energy intensity energy technology and output technology are the three largest energy saving factors in addition to the conventional factors the newly proposed factors also have important effects on china s industrial energy consumption specifically output scale efficiency is an energy saving factor while the energy technological gap output technological gap and energy scale efficiency are drivers of energy consumption this suggests that china s industry is at the stage of returns to scale that is beneficial to output performance but harmful to energy performance meanwhile the widening of the industrial technological gaps has negative impacts on china s industrial energy conservation the proposed decomposition approach can provide information that cannot be obtained from traditional approaches and it can also be applied to many other cases for investigating feasible paths of energy saving and emissions reduction

embedding the drivers of emission efficiency at regional level analyses of namea data abstract this paper provides new empirical evidence on regional national disparities in environmental efficiency based on analyses of namea data referring to italy and the lazio region where rome is the main city shift share analyses provide evidence on the drivers of environmental efficiency and on sector specificity our evidence shows that although the region around rome has achieved higher environmental performance compared to italy mainly thank to its being less industry based some critical points in the energy sector and in some services should be taken into account in shaping the future development of the region in addition the use of regional namea for econometric investigations of emission efficiency drivers at national level shows that though north south disparities favour northern and richer regions in accordance with development oriented dynamics environmental hot spots driven by specialisation and efficiency related issues also appear in some northern industrial regions further the role of public ad private r d is of main relevance in enhancing emission on economic value ratios environmental industrial and sector oriented policy making may derive valuable information from the evidence provided by our study that highlights how analytical exploitation of namea offers rich array of insights for regional policy making

research productivity over the life cycle evidence for academic scientists the relationship between age and the publishing productivity of ph d scientists is analyzed using data from the survey of doctorate recipients national research council and the science citation index the longitudinal nature of the data allows for the identification of pure aging effects in five of the six areas studied life cycle aging effects are present only in particle physics where scientists often speak of being on a religious quest is the indication that scientific productivity is not investment motivated vintage effects are also considered the expectation that the latest educated are the most productive is not generally supported by the data copyright 1991 by american economic association

identifying critical supply chain paths that drive changes in co2 emissions abstract to address the problem of global warming it is important to identify the supply chain paths that drive changes in life cycle co2 emissions and provide both policy makers and decision makers with the information on the critical paths in order to efficiently reduce the co2 emissions in this article i extract and analyze the factors and key supply chains involved in changes in co2 emissions associated with japan s overall demand from 1990 to 2000 using the structural path decomposition spd method applied to the 1990 1995 2000 linked japanese environmental input output tables at the four digit commodity classification level the results reveal that the volume of co2 emissions increased as a result of changes in the input structure of the electricity of the services sector such as electricity amusement and recreation facilities household demand electricity retail trade household demand and electricity public administration local local government demand indicating increasing dependence of services on energy input i also find that the final demand shift changed co2 emissions for example the rise in demand for integrated circuits in exports has contributed to increasing co2 emissions generated from electricity the fall in demand for frozen fish and shellfish in household demand has contributed to decreasing co2 emissions from marine fisheries

economic and environmental effects of a co2 tax in latin american countries abstract the environmental extension from the leontief pricing model is used to simulate the economic and environmental effects of setting different co2 tax rates in three latin american countries brazil mexico and chile it considers a regulatory scenario in which the tax is applied only to emissions from the electricity sector and another scenario in which tax is applied to emissions from all economic sectors the results show that the effects of a co2 tax on sectoral prices and emissions in each country are very different for the same tax rate but these effects are similar in each country when comparing both regulatory scenarios this is explained by the composition carbonization of the electric generation and energy matrix of each of the countries which significantly affects the effectiveness of co2 taxes to reduce emissions in addition the economic sectors most affected by the different regulatory scenarios are similar in all countries

urban unemployment terms of trade and welfare it is generally accepted prior to 1970 that a deterioration in the terms of trade results in lower social welfare in particular prebisch 11 and singer 12 have expressed the basic concern with the terms of trade the secular deterioration in the terms of trade facing less developed countries ldcs leads to income and welfare losses batra and pattanaik 2 nevertheless shows that a deterioration in the terms of trade in the presence of an intersectoral wage differential may raise welfare bhagwati and brecher 5 demonstrate that a decline in the terms of trade can improve real income if capital is mobile internationally recently anam 1 obtains a similarly interesting result for an economy engaging in quota induced rent seeking activities it is notable that none of these studies considers a key feature inherent in a typical ldc namely the existence of substantial urban unemployment thus the purpose of this paper is to examine the welfare impacts of terms of trade losses for ldcs plagued by pervasive urban unemployment the well known harris todaro 7 framework of sector specific unemployment is utilized in addition we derive and contrast various welfare effects of a change in the terms of trade when a ldc pursues alternative import substitution policies i e tariffs vs quotas over the short vs the long run the paper is organized as follows section ii develops the model and provides the transformation relation between urban and rural outputs section iii examines the welfare effects of an exogenous shift in the terms of trade for a tariff or quota distorted economy in the short run as well as in the long run finally concluding remarks are set out in section iv

economic energy and greenhouse emissions impacts of some consumer choice technology and government outlay options abstract the impacts of selected spending options in the australian economy are determined in terms of energy consumption greenhouse gas emissions and a range of economic parameters six case studies of one current practice and one alternative environmentally motivated spending option are carried out describing consumer choices technologies and government outlays the assessment method is based on input output theory and as such enables both the direct and indirect effects of spending to be quantified in general the results indicate that pro environmental objectives such as reductions in energy consumption and greenhouse gas emissions are compatible with broad socio economic benefits such as increases in employment and income and reductions in imports

incentives in university technology transfers there are two main ways in which the knowledge created in universities has been transferred to firms licensing agreements and the creation of spin offs in this paper we describe the main steps in the transfer of university innovations the main incentive issues that appear in this process and the contractual solutions proposed to address them

comprehensive evaluation of household indirect energy consumption and impacts of alternative energy policies in china by input output analysis abstract households consume a large amount of indirect energy through the consumption of goods and services this fact makes the quantitative analysis of indirect household energy consumption the foundation of energy policy design this paper improves the compilation method of energy input output tables and establishes a sequence of energy input output tables for china based on these tables the indirect energy consumption of both rural and urban households is calculated then with economic data for the year of 2005 the adjusted input output price model is applied to evaluate how the alternative energy policies impact production prices consumption prices and real income of rural and urban households through the mechanism of indirect energy consumption by using electricity as an example this research has practical implications for chinese economy the integration of energy efficiency improvements and energy prices increase serves as a means to achieve both economic and energy conservation goals and may also have a positive effect on residents real income and a minimal effect on production prices

milestone payments or royalties contract design for r d licensing we study how innovators can optimally design licensing contracts when there is incomplete information on the licensee s valuation of the innovation and limited control over the licensee s development efforts a licensing contract typically contains an up front payment milestone payments at successful completion of a project phase and royalties on sales we use principal agent models to formulate the licensor s contracting problem and we find that under adverse selection the optimal contract structure changes with the licensee s valuation of the innovation as the licensee s valuation increases the licensor s optimal level of involvement in the development directly or through royalties should decrease only a risk averse licensor should include both up front and milestone payments moral hazard alone is not detrimental to the licensor s value but may create an additional value loss when combined with adverse selection our results inform managerial practice about the advantages and disadvantages of the different terms included in licensing contracts and recommend the optimal composition of the contract

step by step the benefits of stage based r d licensing contracts we examine how a licensor can optimally design licensing contracts for multi phase r d projects when he does not know the licensee s project valuation leading to adverse selection and cannot enforce the licensee s effort level resulting in moral hazard we focus on the effect of the phased nature typical of such projects and compare single phase and multi phase contracts we determine the optimal values for the upfront payment milestone payments and royalties and the optimal timing for outlicensing including multiple milestones and accompanying payments can be an effective way of discriminating between licensees holding different valuations without having to manipulate the royalty rate which induces licensees to invest less resulting in lower project values and socially suboptimal solutions interestingly we also find that multiple milestone payments are beneficial even when the licensor is risk averse contrary to standard contract theory results which recommend that only an upfront payment should be used in terms of licensing timing we show that the optimal time depends on the licensor s risk aversion the characteristics of the licensee and the project value

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

technology transfer with moral hazard abstract this paper develops an incomplete contract model of the licensing relationship that is susceptible to the moral hazard problem the optimal contractual form of licensing derived in the model generates predictions that seem to be consistent with actual practice for instance the introduction of inputs that are not contractible and costly explains the prevalence of royalty contracts in the licensing relationship moreover the model is able to relate the size of the royalty rate to the parameters that represent the environments under which the concerned parties operate finally the model can be naturally extended to analyze the choice of a technology holder between direct investment and licensing in an attempt to serve a foreign market

scale technique and composition effects in trade related carbon emissions in china this study applies structural decomposition analysis to evaluate the scale composition and technique effects of trade related carbon emissions in china mainland from 1987 to 2007 the initial findings indicate that the increasing magnitude of china s trade both in terms of the carbon emissions embodied in exports and the carbon emissions avoided via imports had large scale effects during the whole period the technique effect caused by changes in input mix sector energy intensity fuel mix and carbon coefficients effectively offset part of the scale effect during the entire period but failed to do so during some sub periods changes in trade composition caused a relative small increase in the carbon emissions created by exports but a relative small decrease in the carbon emissions avoided via imports during the whole period

walking away from a low carbon economy recent and historical trends using a regional decomposition analysis using the latest available data this brief article attempts to provide the first regional decomposition analysis of co2 emissions from fuel combustion covering eight regions of the world determinants are estimated in relative and absolute terms for the period 1971 2010 we take the 2010 global surge in co2 emissions as an entry point for the analysis overall results show that most regions have recently performed worse than their historical trends and lack of meaningful progress is identified whereas specific drivers for certain regions suggest some level of continuous improvement e g reduced energy intensity in asia they are incapable of offsetting the effects of economic growth and energy use with the exception of africa most regions appear to have missed the low carbon economy opportunity provided by the 2008 2009 global financial crisis results suggest a lack of serious environmental effectiveness of regional policy portfolios aiming at reducing co2 emissions highly ambitious energy efficiency and renewable energy policies across all regions are immediately needed additionally absolute reductions in co2 emissions and energy use from fossil fuels are urgently required in rich regions if we are to align production and consumption patterns with maintaining global warming below the 2 c threshold

efficiency performance and regulation of the international gas industry a bootstrap dea approach abstract natural gas has become increasingly important as a source of energy in recent years it is widely viewed as an attractive means of realizing environmental objectives post kyoto and individual country gas industries have been extensively restructured to encourage investment from the private sector barriers to international trade in gas have fallen particularly in areas such as europe and asia as pipeline facilities have expanded and trading systems have become established an important question for policy makers concerns the use of scarce resources by this expanding industry regulatory authorities increasingly use efficiency comparators to incentivise minimum cost use of resources by price cap methods yardstick competition and other techniques this paper explores some of the policy developments which affect efficiency of resource use in the gas industry and uses data envelopment analysis to measure relative performance at the individual country level recent developments in bootstrapping techniques are used to correct efficiency estimates for bias and to assess the uncertainty surrounding such estimates the implications of these results for regulatory authorities are then explored

licensing of university inventions the role of a technology transfer office abstract we develop a theoretical model to explain the specific role of technology transfer offices ttos in licensing university inventions using a framework where firms have incomplete information on the quality of inventions we develop a reputation argument for the tto to reduce the asymmetric information problem our results indicate that a tto is often able to benefit from its capacity to pool innovations across research units and to build a reputation within universities we identify when the technology seller will have an incentive to shelve some of the projects thus raising the buyer s beliefs on expected quality this results in fewer but more valuable innovations being sold at higher prices we explain the importance of a critical size for the tto to be successful as well as the stylized fact that ttos may lead to fewer licensing agreements but higher income from innovation transfers

the impact of domestic trade on china s regional energy uses a multi regional input output modeling to systematically reveal how domestic trade impacts on china s regional energy uses an interprovincial input output modeling is carried out to address demand derived energy requirements for the regional economies in 2007 based on the recently available data both the energy uses embodied in final demand and interregional trade are investigated from the regional and sectoral insights significant net transfers of embodied energy flows are identified from the central and western areas to the eastern area via interregional trade shanxi is the largest energy producer and interregional embodied energy deficit receiver in contrast to guangdong as the largest energy user and surplus receiver by considering the impacts of interregional trade the energy uses of most eastern regions increase remarkably for instance shanghai hainan zhejiang beijing jiangsu and guangdong have their embodied energy requirements 87 49 19 97 13 64 12 60 6 46 and 6 38 times of their direct energy inputs respectively in contrast the embodied energy uses of some central and western regions such as inner mongolia shanxi xinjiang shaanxi and guizhou decrease largely the results help understand the hidden network linkages of interregional embodied energy flows and provide critical insight to amend china s current end reduction oriented energy policies by addressing the problem of regional responsibility transfer

quantifying the impacts of energy price reform on living expenses in saudi arabia abstract as part of vision 2030 saudi arabia has initiated a broad based energy reform programme aimed at gradually reducing its dependence on oil this paper assesses the impacts of energy price reforms on living expenses of various household groups in saudi arabia for this purpose the input output table combined with household expenditure data are used to model the impacts results show that the distributional impacts of energy price reforms are regressive with low income households experiencing a higher increase in living expenses compared to high income households the impacts are primarily instigated by rising prices of energy intensive products after decomposing the impacts into direct and indirect effects it was found that indirect effect is not only responsible for a considerable rise in household expenditure on energy intensive products but it is also distributionally regressive it is therefore vital for policymakers to review and fine tune the social protection system to protect poor households against reforms

has energy efficiency performance improved in china non energy sectors evidence from sequenced hybrid energy use tables we conduct a comparative analysis of two energy efficiency indicators for china heating value energy intensity hei and economic value energy intensity mei we formulate 1997 2002 2007 2012 hybrid energy comparable sequence use tables in an input output accounting framework and compare the two indicators using a randomized block anova the results show that meis and heis have significantly different variability patterns among sectors and are evolutionarily divergent over time the directional changes in mei and hei are found to be inconsistent at both the sectoral and national levels a further analysis with a lmdi index decomposition model shows that the difference between hei lmdi and hei lmdi is principally caused by energy prices based on the evidence from the two indicators and their relationship to energy prices we are unconvinced about china s purported improvements in energy efficiency in recent years

input output simulations of energy environment economy interactions in the uk this paper shows how a number of the complex interrelationships between energy environment and economic welfare can be investigated with the aid of a 10 sector input output i o model of the uk with pollution emission coefficients and a european sulphur deposition vector the paper reviews relevant past applications of i o analysis in the energy environment area and describes the endam program and its operation it is used to simulate the effects of a variety of policies and possibilities not only through changes in exogenous variables final demand and income taxes and transfers but also through changes in the structural matrices and their coefficients in each case the full effects direct indirect and income induced can be traced and the changes in comparative static equilibrium values discovered in this way policy issues connected with energy use and environmental impacts employment and economic welfare have been investigated

interactions in swiss households energy demand a holistic approach abstract this article analyzes the interactions and possible trade offs between direct energy consumption and embodied energy requirement of households in switzerland in order to assess the net impacts of standard energy policies focusing exclusively on direct energy use direct and embodied energy demand of swiss households are estimated by combining consumption data of a national expenditure survey with data on energy intensity from life cycle analysis using a system of equations and an instrumental variable approach we find that both domains are driven by same determinants but that there is no evidence for significant substitution between them we also find an increasing effect of income on both domains with particularly important effects on embodied energy from a policy perspective our findings highlight a concern that economic growth could bring about an increasing global energy demand through energy requirement for non energy commodities however the wide spread policies targeting direct energy are unlikely to cause a substantial shift in household consumption to embodied energy

driving forces of rapid co2 emissions growth a case of korea abstract this study aims to investigate korea s final demand structure and its impacts on co 2 emissions in order to reduce co 2 emissions and develop environmental policy directions based on the environmentally extended input output model this study adopts a two step approach 1 to estimate the embodied emissions and their intensities for 393 sectors induced by final demand and 2 to calculate the driving factors of emission growth between 2003 and 2011 and then evaluate the result by using structural decomposition analysis sda the findings of this study demonstrate that the impact of composition change in export with less embodied emission intensities tends to offset the increase in co 2 emission by the export scale growth the relatively low residential electricity price has resulted in the rapid growth of household electricity consumption and significantly contributed to emissions growth the result of sda indicates that korea s final demand behavior yielded high carbonization over the same period the findings suggest that korean government should promote exports in industries with less embedded co 2 in order to protect environments in addition emission information of each product and service should be provided for consumers to change their purchase patterns towards contributing to low carbon emissions as active players

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

the shadow price of foreign exchange in a dual economy abstract this paper examines the shadow price of foreign exchange for a dual economy with tariffs quotas or vers we show that the shadow exchange rate is greater than the official rate in the presence of tariffs whereas it is greater or smaller than the official rate in the presence of quotas depending upon whether capital is sector specific or perfectly mobile furthermore the shadow exchange rate is unambiguously smaller than the official rate for the ver case when capital is intersectorally mobile the rate however may be larger than the official rate when capital is sector specific the practical implications of the results for project appraisal are also discussed

shirking sharing risk and shelving the role of university license contracts abstract in this paper we develop a theoretical model of university licensing to explain why university license contracts often include payment types that differ from the fixed fees and royalties typically examined by economists our findings suggest that milestone payments and annual payments are common because moral hazard risk sharing and adverse selection all play a role when embryonic inventions are licensed milestones address inventor moral hazard without the inefficiency inherent in royalties the potential for a licensee to shelve inventions is an adverse selection problem which can be addressed by annual fees if shelving is unintentional but may require an upfront fee if the firm licenses an invention with the intention to shelve it whether the licensing contract prevents shelving depends in part on the university credibly threatening to take the license back from a shelving firm this supports the rationale for bayh dole march in rights but also shows the need for the exercise of these rights can be obviated by contracts

possibility or impossibility of paradoxes in the small country harris todaro framework a unifying analysis abstract in this paper we argue that the harris todaro ht framework sometimes satisfies an envelope property which makes it work like a full employment heckscher ohlin samuelson hos model then the ht structure produces very similar results as one gets in the standard hos framework differences arise because the envelope condition may break down we show how several celebrated results in the ht structure can have this reinterpretation
