international consumption risk sharing this paper formally examines the implications of international consumption risk sharing for a panel of industrialized countries we theoretically derive the international consumption insurance proposition in a simple setup and show how to modify it in more complicated models we analyze the implications of the theory for pairs of countries and find that aggregate domestic consumption is almost completely insured against idiosyncratic real demographic fiscal and monetary shocks over short cycles but that it covaries with these variables over medium and long cycles the cross equation restrictions imposed by the theory are rejected the policy implications are discussed

china s oil use 1990 2008 abstract over the past two decades china s oil demand has risen steeply in 1990 it was only about 25 higher than that of 1978 the year economic reform was introduced by 2008 it had reached 396 0 million tons roughly four times the 1978 level making china the second largest oil user worldwide the country became a net oil importer in 1993 and between 1993 and 2008 its net import dependency a yardstick for energy security soared from 7 5 to 50 0 china s increased demand for oil has made the country a global energy player of critical importance although the literature on the global implications of china s oil use has proliferated relatively few studies have attempted to examine how china uses oil hence this study covers every oil consuming facility and sector in china exploring the patterns of and factors involved in oil demand by power plants oil refineries heat plants and gas works and industrial transport agricultural household and commercial sectors it concludes that in virtually all sectors in china oil demand will grow with transport and industry leading the way

fiscal federalism and interstate risk sharing empirical evidence from germany abstract using an approach developed by asdrubali et al quarterly journal of economics 111 1996 1081 the paper estimates the extent of smoothing of state specific income shocks to west german states from 1970 to 1997 by federal fiscal institutions the results show that despite the existence of substantial interregional transfer mechanisms the share of shocks to state income absorbed by fiscal flows is roughly at the same level as in the us

no free ride to zero emissions simulating a region s need to implement its own zero emissions vehicle zev mandate to achieve 2050 ghg targets abstract the adoption of zero emission vehicles zevs is limited by a variety of barriers some are region specific e g availability of charging infrastructure while others are global in nature e g battery prices where improvements spill over between regions this study explores regional spillover effects and ghg impacts of strong zev focused policy specifically the zev mandate in place in ten u s states zev states which requires automakers to sell a minimum amount of zevs each year we use a dynamic technology adoption model to simulate passenger vehicle sectors in north america focusing on the case of one small region british columbia covering 0 7 of the market as potentially free riding off of zev states policy covering 23 of the market results indicate that free ridership is not effective even with the zev mandate driving very high sales in zev states british columbia cannot achieve significant zev adoption without also implementing its own zev mandate further for british columbia to meet its 2050 ghg targets it may need a zev mandate in addition to complementary climate policies pushing zevs to account for 40 93 of new vehicle sales in 2050 in short regions seeking low carbon transportation likely need to implement their own stringent policies

the real effects of financial integration abstract this paper shows how correlations in gdp fluctuations rise with financial integration finance serves to increase international correlations in both consumption and gdp fluctuations which explains the persistent gap between the two in the data a quantity puzzle the positive association between financial integration and gdp correlation constitutes a puzzle as theory suggests a negative relation if anything nevertheless it prevails in the data even after the effects of finance on trade and specialization are accounted for

exploring the potential for energy conservation in french households through hybrid modeling although the building sector is recognized as having major potential for energy conservation and carbon dioxide emissions mitigation conventional bottom up and top down models are limited in their ability to capture the complex economic and technological dynamics of the sector this paper introduces a hybrid framework developed to assess future household energy demand in france res irf a bottom up module of energy consumption for space heating has several distinctive features i a clear separation between energy efficiency i e investment in energy efficient technologies and sufficiency i e changes in the utilization of energy consuming durables which allows the rebound effect to be assessed ii the inclusion of barriers to energy efficiency in the form of intangible costs consumer heterogeneity parameters and the learning by doing process iii an endogenous determination of retrofitting which represents trade offs between retrofit quantity and quality subsequently res irf is linked to the imaclim r computable general equilibrium model this exercise shows that compared to a 37 reduction in final energy demand achievable in business as usual in existing dwellings an additional reduction of 14 could be achieved if relevant barriers to efficiency and sufficiency were overcome

exploring the core factors and its dynamic effects on oil price an application on path analysis and bvar tvp model abstract as the uncertainty of oil price increases impacts of the influential factors on oil price vary over time it is of great importance to explore the core factors and its time varying influence on oil price in view of this based on the path analysis model this paper obtains the core factors builds an oil price system var model which uses demand supply price and inventory as endogenous variables and china s net imports as well as dollar index as exogenous variables then we set up a bvar tvp time varying parameter model to analyze dynamic impacts of core factors on oil price the results show that 1 oil prices became more sensitive to oil supply changes and the influence delays became shorter 2 the impact of oil inventories on oil prices with a time lag of two quarters but has a downward trend 3 the impact of oil consumption on oil prices with a time lag of two quarters and this effect is increasingly greater 4 the us dollar index is always the important factor of oil price and its control power increases gradually and the financial crisis occurred in 2008 further strengthens the influence of us dollar

tastes and technology in a two country model of the business cycle explaining international trade on international financial markets allows people to insure country specific risk and smooth consumption intertemporally equilibrium models of business cycles with trade on global financial markets typically yield international consumption correlations near one and excessive volatility of investment the authors incorporate nontraded goods in the model and find that the implications for aggregate consumption investment and the trade balance are consistent with business cycle properties of industrialized countries however the model driven by technology shocks alone yields counterfactual implications for comovements between consumption and prices at the sectoral level taste shocks produce price quantity relationships more consistent with the data copyright 1995 by american economic association

trying to explain home bias in equities and consumption investors hold a substantially larger proportion of their wealth portfolios in domestic assets than standard portfolio theory would suggest a phenomenon called equity home bias in the absence of this bias investors would optimally diversify domestic output risk using foreign equities therefore consumption growth rates would tend to co move across countries even when output growth rates do not empirically however consumption growth rates tend to have a lower correlation across countries than do output growth rates a phenomenon i call consumption home bias in this paper i discuss these two biases and their potential relationship as suggested by the literature

testing the response of consumption to income changes with noisy panel data this paper tests the rational expectations lifecycle model of consumption against i a keynesian model and ii the rational expectations lifecycle model with imperfect capital markets the tests are based upon the relative responsiveness of consumption to income changes that can be predicted from past information and income changes that cannot he predicted the tests allow for measurement error in income the results reject the keynesian model and generally support the lifecycle model but the results are not sufficiently precise to rule out the possibility that some households are liquidity constrained measurement error has a strong influence on the relationship between consumption and income

the emergence of rural transport strategies in response to rising fuel costs abstract rising and sometimes volatile fuel prices pose a challenge for rural organizations reliant on long distance transport to understand the coping mechanisms used by such organizations we survey rural business strategies in israel where fuel prices are high and urban development is concentrated in the country s geographic center the businesses surveyed are operated by kibbutzim historically collective communities that are now in various stages of privatization analysis of the transport strategies employed by nearly 100 organizations in three regions of varying remoteness and isolation shows that firms rely on distinct strategies such as localization and high value density localization was found to be prevalent in all regions as it requires little capital investment strategies exploiting high value density including information based services were prevalent in remote and isolated regions where sensitivity to transport costs is acute non remote firms were less inclined toward strategic adaptation preferring non disruptive changes such as cheaper shipping modes the development implications of these transport strategies are consistent with rural economic trends observed throughout the developed world if transport costs continue to rise rural firms may shrink the radius of their sales and labor pools or search for more lucrative products to reduce their relative transport costs

picking winners modelling the costs of technology specific climate policy in the u s passenger vehicle sector abstract researchers debate the cost effectiveness of technology specific versus technology neutral climate policies but few quantify the differences using the case of low carbon vehicle technologies in the us passenger vehicle sector ethanol plug in electric and hydrogen we develop a technology adoption simulation model that represents increasing returns to adoption in both financial costs and consumer preferences representing uncertainty through monte carlo analysis we compare the policy costs tonne co2 out to 2050 of i a technology neutral carbon tax ii a somewhat neutral vehicle standard requiring low carbon vehicle sales but allowing competition among technologies and iii technology specific vehicle standards requiring sales of just one technology on average across simulations the carbon tax is twice as cost effective as the best vehicle standard in part because the tax more substantially affects vehicle use rates among the vehicle standards a technology specific standard that selects the right winner plug in electric vehicles is more cost effective than the neutral standard as it more quickly stimulates technology improvement however there is risk in a technology specific approach mistakenly forcing a loser technology hydrogen results in policy costs that are 2 to 5 times higher than other policies results can help policymakers trade off the costs and risks of different climate policy options

implications of delaying transport decarbonisation in the eu a systems analysis using the primes model abstract the transport sector decarbonisation represents an essential part of the ghg emissions reduction strategy of the eu for the 2030 and 2050 horizon the strategy presumes a far reaching structural system change towards the marketing of advanced electrified powertrains and use of energy carriers such as electricity and hydrogen that are generated in a carbon free way the decade 2020 2030 is expected to set in motion the complex process of the necessary transformation of the power generation and transport systems which mandates the successful coordination of the interrelated market actors consumers and policy makers this paper presents a systems analysis that aims to assess what would happen if the decarbonisation strategy fails to develop as anticipated during the decade 2020 2030 we refer to this timeframe as the lost decade to answer this question our analysis is based on counterfactual scenarios quantified using the primes energy systems model the analysis concludes that the decade 2020 2030 is a critical point in this transformation limited progress in the coming decade would require the adoption of stringent policy measures beyond 2030 which along with the pressure to reduce emissions in a short period are found to increase substantially the total costs of the system

electric vehicles rising from the dead data needs for forecasting consumer response toward sustainable energy sources in personal transportation abstract since standard vehicles are powered by internal combustion mechanisms that rely on fossil fuels electric vehicles that are propelled by one or more electric engines have been proposed as an alternative to promote sustainable personal transportation in this paper we propose a general demand model for vehicle purchases at the individual level assuming that the necessary microdata is available we then list the ideal microdata that would be needed for estimating this general demand model for elaborating this list we take into account the particularities of low emission vehicles with emphasis in their cost reliability environmental benefits tradeoff as well as the potentiality for evaluation of welfare improving policies related to adoption of energy efficient technologies we discuss data sources and collection strategies for the different attributes of the model especially for those characteristics that are nonstandard such as symbolic values for instance we discuss the role of range anxiety as a barrier of adoption of electric vehicles and the implied relevance of including driving range to get consumers willingness to pay for better performing electric batteries

passenger transport modal split based on budgets and implication for energy consumption approach and application in china transport will be the strongest growing energy demand sector in the future especially in developing countries like china and it needs more attention the evolution of transport structure is very important in the dynamic of transport development and therefore worth emphasis in this study a modal split model maximizing spatial welfare and constrained by travel money budget and time budget is developed this approach differs from the general econometric based approach used in most existing macro transport studies and deals with the cost and speed of transport modes as important variables explicitly the model is then applied to china s transport sector together with sensitivity test despite many data problems the decomposition of energy consumption generated from bottom up model based on this modal split identified the importance of modal split and turnover expansion in the next 30 years which should be a stronger area of focus in transportation studies

an empirical study of direct rebound effect for passenger transport in urban china transport sector accounts for about 8 of total energy consumption in china and this share will likely increase in the visible future improving energy efficiency has been considered as a major way for reducing transport energy use whereas its effectiveness might be affected by the rebound effect this paper estimates the direct rebound effect for passenger transport in urban china by using the linear approximation of the almost ideal demand system model and simulation analysis our empirical results reveal the existence of direct rebound effect for passenger transport in urban china a majority of the expected reduction in transport energy consumption from efficiency improvement could be offset due to the existence of rebound effect we have further investigated the relationship between the magnitude of direct rebound effect and households expenditure it was found that the direct rebound effect for passenger transport tends to decline with the increase of per capita household consumption expenditure

channels of interstate risk sharing united states 1963 1990 we develop a framework for quantifying the amount of risk sharing among states in the united states and construct data that allow us to decompose the cross sectional variance in gross state product into several components which we refer to as levels of smoothing we find that 39 percent of shocks to gross state product are smoothed by capital markets 13 percent are smoothed by the federal government and 23 percent are smoothed by credit markets the remaining 25 percent are not smoothed we also decompose the federal government smoothing into subcategories taxes transfers and grants to states

does china factor matter an econometric analysis of international crude oil prices abstract whether china s crude oil imports are the culprit of oil price volatility these years has not been quantitatively confirmed therefore this paper empirically investigates the role of china s crude oil net imports in brent price changes from october 2005 to november 2013 based on an econometric analysis the results indicate that during the sample period china s crude oil imports do not significantly affect brent price changes no matter in the long run or short run therefore the blame for china s crude oil imports to cause the dramatic fluctuations of international oil price has no solid evidence also there exists significant uni directional causality running from the brent price to china s crude oil imports at the 5 level besides the response of the brent price to china s crude oil imports is found positive but slight and the brent price responds more significantly to us dollar exchange rate and oecd commercial inventory than to china s crude oil imports in the short run finally the contribution of china s crude oil imports to brent price movement is about 10 which is less than that of us dollar exchange rate but larger than that of indian crude oil imports or oecd commercial inventory

transport mode choice by commuters to barcelona s cbd this paper analyses the determinants of travel mode choice for suburbanised commuters in barcelona spain after describing the importance of residential suburbanisation and the parallel increase in the share of private car use by commuters into the city centre a nested logit model of transport mode choice is estimated the results reveal low elasticities particularly in the case of car commuters values of travel time savings are high although within the ranges obtained in the literature it is observed that continuing suburbanisation will result in increasing the market share of rail at the expense of the private car use and mainly the bus provided that accessibility to the public transport network is maintained at present levels

strategic oil stockpiling for energy security the case of china and india abstract compared with the developed countries the developing countries could be more vulnerable to oil supply disruptions due to their lack of strategic petroleum reserves sprs several developing countries including china and india are establishing their sprs to ensure energy security in the common world oil market one country s spr decisions can be affected by the decisions of other countries this paper investigates the spr policies of china and india two of the largest developing countries in a game theoretic framework where the interactions between the two countries are taken into account the results show that players equilibrium stockpiling strategies and total expected costs could vary significantly with the initial oil market state stockpile acquisition capacity and the probabilities for disruptions to persist

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

energy policies for managing china s carbon emission abstract the well documented close relationship between economic growth and energy use indicates that the emergence of a country as an economic power cannot occur without increased in energy use but just as the scale of china s rise as an economic power has no clear parallel in history its conflict between economic growth and energy use has also shattered all precedents this planet s future energy scenario hinges on the ability of this decoupling the question this policy forum addressed is how to find the optimum way to accomplish this decoupling through government directive government centered command and control approaches or cac or market forces market based instruments or mbi it concludes that market rather than government can decide the optimum way to decouple china s economic growth from energy use facilitating this decoupling driven by market force requires getting the prices right for energy

union contracts and the life cycle permanent income hypothesis this paper isolates households in the psid whose heads can be matched to particular long term union contracts with high confidence the author uses use published information on these contracts to construct a household specific measure of expected wage growth he finds that predictable wage movements are significantly correlated with consumption changes contrary to neoclassical consumption theory the author finds that consumption responds more strongly to predictable income declines than to predictable income increases this asymmetry is inconsistent with liquidity constraints and myopia but is qualitatively consistent with models in which preferences exhibit loss aversion copyright 1995 by american economic association

international risk sharing and european monetary unification abstract we explore income and consumption smoothing patterns among european community ec countries and among oecd countries during the period 1966 90 we find that for oecd as well as for ec countries about 40 percent of shocks to gdp are smoothed at the one year frequency with about half the smoothing achieved through national government budget deficits and half by corporate saving at the three year differencing frequency only 25 percent of shocks to gdp are smoothed mainly via government lending and borrowing in the absence of alternative income and consumption smoothing mechanisms the restrictions on budget deficits imposed by the maastricht treaty should be relaxed to allow governments to run large temporary deficits in response to output shocks

determinants of china s energy imports an empirical analysis sustained economic growth in china has triggered a surge of energy imports especially oil imports this paper investigates the determinants of china s energy import demand by using cointegraiton and vecm techniques the findings suggest that in the long run growth of industrial production and expansion of transport sectors affect china s oil imports while domestic energy output has a substitution effect thus as the chinese economy industrializes and the automotive sector expands china s oil imports are likely to increase though china s domestic oil production has a substitution effect on imports its growth is limited due to scarce domestic reserve and high exploration costs it is anticipated that china will be more dependent on overseas oil supply regardless of the world oil price

the costs of carbon sequestration a revealed preference approach increased concem by policy makers with the threat of global climate change has brought with it considerable attention to the possibility of encouraging the growth of forests as a means of sequestering carbon dioxide national academy of sciences nas 1992 james p bruce et al 1996 1 the kyoto protocol to the united nations framework convention on climate change 1997 which establishes emission reduction targets for the united states and other industrialized nations states that carbon sequestration can be used by participating nations to achieve their targets moreover even before the kyoto agreement this approach had become an explicit element of both u s and intemational climate policies u s department of energy 1991 united nations general assembly 1992 william j clinton and albert gore 1993 this high level of interest has been due in part to suggestions that sufficient lands are available to use the approach to mitigate a substantial share of annual carbon dioxide c02 emissions greg marland 1988 daniel a lashof and dennis a tirpak 1989 mark c trexler 1991 and claims that growing trees to sequester carbon is a relatively inexpensive means of combating climate change roger a sedjo and allen m solomon 1989 daniel j dudek and alice leblanc 1990 nas 1992 in other words the serious attention given by policy makers to carbon sequestration can partly be explained by implicit assertions about respective marginal cost functions i develop and demonstrate a method by which the costs of carbon sequestration can be estimated on the basis of evidence from landowners behavior when confronted with the opportunity costs of alternative land uses the simplest of previous economic analyses derived single point estimates of average costs associated with particular sequestration levels marland 1988 sedjo and solomon 1989 dudek and leblanc 1990 edwin s rubin et al 1992 omar masera et al 1995 often it has been assumed that land opportunity costs are zero g van kooten et al 1992 j k winjum et al 1992 new york state energy office 1993 robert k dixon et al 1994 another set of studies essentially engineering costing models has constructed marginal cost schedules by using information on revenues and costs of production for altemative uses on representative types or locations of land and then sorting these in ascending order of cost robert j moulton and kenneth r richards 1990 richards et al 1993 simulation models include a model of the lost profits due to removing land from agricultural production peter j parks and ian w hardie 1995 a mathematical programming model of the agricultural sector and the timber market richard m adams et al 1993 a related model incorporating the effects of agricultural price support programs j m callaway and bruce mccarl 1996 and a dynamic simulation model of forestry susan swinehart 1996 lastly an analysis by andrew j plantinga 1995 adopts land use elasticities from an econometric study to estimate sequestration costs we draw on some of the best features of the previous studies including the carbon levelization method of moulton and richards john f kennedy school of government harvard university 79 john f kennedy street cambridge ma 02138 and resources for the future richard newell supplied excellent research assistance and valuable comments on a previous version were provided by lawrence goulder william nordhaus andrew plantinga kenneth richards two anonymous referees participants in seminars at the universities of california at los angeles and santa barbara the university of maryland the university of michigan the university of texas harvard university stanford university yale university resources for the future and the national bureau of economic research the author alone is resdonsible for any errors 1 after fossil fuel combustion deforestation is the second largest source of carbon dioxide emissions estimates of annual global emissions from deforestation range from 0 6 to 2 8 billion tons compared with slightly less than 6 0 billion tons annually from fossil fuel combustion cement manufacturing and natural gas flaring combined r a houghton 1991 t m smith et al 1993

a review on global fuel economy standards labels and technologies in the transportation sector abstract globally the transportation sector is the second largest energy consuming sector after the industrial sector and accounts for 30 of the world s total delivered energy in 2008 the transportation sector accounted for about 22 of total world co2 emissions it is believed that this sector is currently responsible for nearly 60 of world oil demand within this sector road vehicles dominate oil consumption and represents 81 of total transportation energy demand the purpose of this paper is to highlight the possible opportunities to improve fuel economy and thus reduce global oil consumption and greenhouse gases there are three measures that have been reviewed passenger vehicle fuel economy and greenhouse gas emission standards fuel economy labels and improvement in vehicle fuel efficiency by advanced technologies fuel economy and greenhouse gas emission standards have proven to be one of the most effective tools in improving fuel economy japan and europe lead the world with the most stringent passenger vehicle fuel economy standards labeling is another measure that could play an important role in consumers vehicle purchasing decisions between similar vehicles labeling accompanied by standards of an appropriate type and level of stringency may yield synergistic results in this review several examples of fuel economy labels around the world have been presented such as in usa united kingdom canada china and australia finally advanced technologies have been discussed there are many technical opportunities to improve fuel efficiency and economy of motor vehicles in this review the possibilities of reducing vehicle power requirement advanced engine and transmission technology and alternative power plants have been reviewed it has been found that fuel economy standards labels and technologies offer a massive potential of energy saving that can be achieved in this sector and thus the authors promoted adopting these measures in the transportation sector

risk sharing from international factor income explaining cross country differences access to world capital markets and net investment income flows between countries help protect national income from country specific output shocks i empirically study what factors explain cross country differences in the extent of risk sharing from international factor income an index of investor protection is the leading causal variable for the estimated amount of risk sharing over the 1985 to 2004 period improving investor protection in russia to denmark s level implies five times larger risk sharing compared to the sample average these results indicate one possible way to reap large potential benefits from international risk sharing

myopia liquidity constraints and aggregate consumption a simple test this note conducts a simple test for myopia and liquidity constraints in aggregate u s consumption the test exploits the fact that under myopia consumption should be equally sensitive to predictable income declines and increases while under liquidity constraints consumption should be more sensitive to predictable income increases than to declines using quarterly postwar data the author shows that aggregate consumption is in fact more sensitive to predictable income declines than increases this perverse asymmetry is inconsistent with both myopia and liquidity constraints but is qualitatively consistent with recent theoretical work incorporating loss aversion into intertemporal preferences

what can explain the apparent lack of international consumption risk sharing recent research in international business cycles finds that international consumption comovements do not match the risk sharing predictions of standard complete markets models in this paper i ask whether two different types of explanations can help explain this result 1 nonseparabilities between tradables and nontradable leisure or goods and 2 the effects of capital market restrictions on consumption risk sharing i find that risk sharing cannot be resolved by either explanation alone however when i allow for both nonseparabilities and certain market restrictions risk sharing among unrestricted countries cannot be rejected this evidence suggests that a combination of these two effects may be necessary to explain consumption risk sharing across countries

do emerging markets matter in the world oil pricing system evidence of imported crude by china and india abstract this paper provides empirical evidence on the changing structure of world oil price system by identifying an additional driver emerging market factor we choose china and india as a representative of emerging markets to examine if the quantity of crude oil imported by china and india is significant in the existing oil pricing system kaufmann et al 2004 our data starts from january 2002 and ends in march 2010 which includes the oil shock of 2007 2008 we utilize cointegration and error correction model framework developed by engle granger 1987 and gregory hansen 1996 in the analysis our results indicate that demand from emerging markets has become a significant factor in the world oil pricing system since 2003 this result is significant as it lends empirical support to the widely held conjecture that the oil shock of 2007 2008 is a demand led shock hamilton 2009 our result also has significant policy implications that go beyond the oil shock the emerging market factor is there to stay and reflects the changing power between emerging and developed economies in the world economic system as a result of decades of fast economic development in the former it will certainly influence policy issues related to oil and beyond

china on the move oil price explosion abstract rapid expansion of highway and jet traffic in china has created a surge of demand for oil products putting pressure on world energy markets and petroleum product prices this paper examines trends in freight and passenger traffic to assess how growth in china s transport demand relates to growth in china s economy as well as the energy intensity of transport based on assumptions about demand elasticity and energy intensity a range of scenarios is developed for china s oil demand through 2020 incremental oil demand from china s transport sector is then compared with world oil demand projections to assess the likely impact on world oil prices the finding is that new demand from china s transport sector would likely raise world oil prices in 2020 by 1 3 in reference scenarios or by 3 10 if oil supply investment is constrained

improving behavioral realism in hybrid energy economy models using discrete choice studies of personal transportation decisions hybrid energy economy models combine top down and bottom up approaches to explore behaviorally realistic responses to technology focused policies this research uses empirically derived discrete choice models to inform key behavioral parameters in cims a hybrid model the discrete choice models are estimated for vehicle and commuting decisions from a survey of 1150 canadians with the choice models integrated into cims we simulate carbon taxes gasoline vehicle disincentives and single occupancy vehicle disincentives to show how different policy levers can motivate technological change we also use the empirical basis for the choice models to portray uncertainty in technological change costs and emissions

consumption risk sharing in italy this paper analyses the issue of consumption risk sharing in the 20 italian regions during the period 1983 94 the tests proposed allow for regional specific departures from the hypothesis of complete risk sharing and for the existence of non separabilities among groups of commodities empirical evidence suggests the rejection of the hypothesis of complete consumption risk sharing

borrowing constraints and international risk sharing evidence from asymmetric error correction we analyse the adjustment process of consumption growth after disequilibrating output shocks in a sample of organization for economic cooperation and development oecd countries in particular we test the hypothesis that consumption is smoothed to a lesser degree after negative shocks whereas the impact of a positive shock is delayed for a longer period of time our analysis is based on an error correction framework that allows for asymmetric adjustment we find that the mean adjustment lag after a negative shock is significantly shorter than after a positive shock especially since the beginning of the 1980s this result is consistent with the interpretation that borrowing constraints limit the degree to which the impact of negative shocks on consumption can be smoothed

oil development in china current status and future trends the future of oil has become an important topic of the discussion of energy policy in china this paper attempts to present a full picture of the current status and future trends of china s oil development through system analysis first we map a sankey diagram of china s oil flow to reveal the physical pattern of china s oil supply and consumption then we present the historical and ongoing trends of china s oil flow from key aspects such as oil demand oil resource availability technology improvement and policy adjustment based on these understandings we design three scenarios of china s oil demand in 2030 and analyze policy implications for oil saving automotive energy development and energy security from the analysis we draw some conclusions for policy decisions such as to control the total oil consumption to avoid energy security risks to enhance oil saving in all sectors with road transportation as the emphasis and to increase the investment on oil production and refining to secure oil supply and reduce emissions

shocks effects of macroeconomic variables on natural gas consumption in nigeria structural var with sign restrictions abstract this paper has examined the transmission of shocks from macroeconomic variables namely money supply inflation exchange rate and real gdp onto natural gas consumption using structural var svar model with sign restrictions the results revealed that both in the short run and long run natural gas consumption responds significantly to the shocks emanating from money supply and real gdp while its response to inflation shock is significant only in the short run but exchange rate shock is not significant however money supply has contributed greater proportion of the shocks followed by the real gdp inflation and exchange rate in the ordering of the variance decomposition the paper recommends that nigerian authorities adjust the monetary policy tools towards regulating the money supply and checking the inflation rate to ensure increased demand for natural gas and sustained economic growth on the response of natural gas consumption to the shock in the exchange rate since the shock is positive though insignificant it implies that depreciation of the exchange rate can discourage the demand for foreign exchange imports and boost the local production which would reciprocally lead to more natural gas consumption and improved growth in the country

cost effectiveness of greenhouse gas mitigation in transport a review of methodological approaches and their impact abstract a review is given of methodological practices for ex ante cost effectiveness analysis cea of transport greenhouse gas ghg mitigation measures e g fuel economy and co2 standards for road vehicles in the us and eu besides the fundamental differences between different types of policies and abatement options which inherently result in different cea outcomes differences in methodological choices and assumptions are another important source of variation in cea outcomes fourteen methodological issues clustered into six groups are identified on which thirty three selected studies are systematically reviewed the potential variation between lower and upper cost effectiveness estimates for ghg mitigation measures in transport resulting from different methodological choices and assumptions lies in the order of 400 per tonne co2 eq the practise of using cea for policy making could improve considerably by clearly indicating the specific purpose of the cea and its strengths and limitations for policy decisions another improvement is related to the dominant approach in transport ghg mitigation studies the bottom up financial technical approach which assesses isolated effects implying considerable limitations for policy making a shift to welfare economic approaches using a hybrid model has the potential to establish an improved assessment of transport ghg mitigation measures based on realistic market responses and behavioural change

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

the neighbor effect simulating dynamics in consumer preferences for new vehicle technologies abstract understanding consumer behaviour is essential in designing policies that efficiently increase the uptake of clean technologies over the long run expert opinion or qualitative market analyses have tended to be the sources of this information however greater scrutiny on governments increasingly demands the use of reliable and credible evidence to support policy decisions while discrete choice research and modeling techniques have been applied to estimate consumer preferences for technologies these methods often assume static preferences this study builds on the application of discrete choice research and modeling to capture dynamics in consumer preferences we estimate canadians preferences for new vehicle technologies under different market assumptions using responses from two national surveys focused on hybrid gas electric vehicles and hydrogen fuel cell vehicles the results support the relevance of a range of vehicle attributes beyond the purchase price in shaping consumer preferences towards clean vehicle technologies they also corroborate our hypothesis that the degree of market penetration of clean vehicle technologies is an influence on people s preferences the neighbor effect finally our results provide behavioural parameters for the energy economy model cims which we use here to show the importance of including consumer preference dynamics when setting policies to encourage the uptake of clean technologies

do green tech policies need to pass the consumer test the case of ethanol fuel abstract this paper investigates a question sometimes overlooked by policymakers and regulators namely the need of a robust value proposition for green technologies to successfully enter the market in particular results from consumer choice models are used to develop measures of consumer acceptance of ethanol blends and flex fuel vehicles is studied a fuel vehicle system that has received attention in a variety of federal and state policies the analysis suggests that under projected fuel prices and given the characteristics of the competing vehicle fuel systems consumers are unlikely to substitute ethanol blends for gasoline the analysis also highlights the need for further research in this area

public employment and regional risk sharing we provide an empirical analysis of regional risk sharing in norway over the period 1977 90 the approach of asdrubali sorensen and yosha 1996 is extended to take public employment into account as a possible shock absorber the other channels of risk sharing are capital markets and commuting taxes and transfers and credit markets the estimated degree of regional consumption insurance is very high we cannot reject the hypothesis that there is full interregional risk sharing in the short term public employment absorbs up to 25 percent of private sector output shocks in our analyses generally central government insurance against regional shocks is relatively more important the more permanent the shocks are and vice versa for market based risk sharing channels

teaching un sustainability university sustainability commitments and student experiences of introductory economics the three largest public universities in british columbia canada have signed the talloires declaration committing themselves to promoting sustainability and creating expectations that they will integrate sustainability across the curriculum in order to improve students environmental literacy and stewardship about 40 of north american university students take a mainstream introductory economics course few of these students take economics at more advanced levels as such introductory economics courses are an important vehicle for students to learn economic theory they have the potential to contribute to the knowledge that students can mobilize to foster sustainability interviews were held with 54 students who had recently completed an introductory level mainstream economics course at one of the three universities students reported that introductory economics courses place little emphasis on the environment and sustainability they recalled course content with normative connotations that are problematic from a sustainability perspective and they described how discussion of the limitations of mainstream theory was set aside student reports of the insights introductory economics offers into environmental problems imply that these courses are failing to substantively increase students understanding of sustainability and linkages between the environment and the economy findings suggest that current introductory economics curriculum undermines the universities sustainability commitments
