reduction potentials of energy demand and ghg emissions in china s road transport sector abstract rapid growth of road vehicles private vehicles in particular has resulted in continuing growth in china s oil demand and imports which has been widely accepted as a major factor effecting future oil availability and prices and a major contributor to china s ghg emission increase this paper is intended to analyze the future trends of energy demand and ghg emissions in china s road transport sector and to assess the effectiveness of possible reduction measures a detailed model has been developed to derive a reliable historical trend of energy demand and ghg emissions in china s road transport sector between 2000 and 2005 and to project future trends two scenarios have been designed to describe the future strategies relating to the development of china s road transport sector the business as usual scenario is used as a baseline reference scenario in which the government is assumed to do nothing to influence the long term trends of road transport energy demand the best case scenario is considered to be the most optimized case where a series of available reduction measures such as private vehicle control fuel economy regulation promoting diesel and gas vehicles fuel tax and biofuel promotion are assumed to be implemented energy demand and ghg emissions in china s road transport sector up to 2030 are estimated in these two scenarios the total reduction potentials in the best case scenario and the relative reduction potentials of each measure have been estimated

institutions and progress an insistent theme in richard nelson s work is that of capitalism as an engine of progress in this paper i explore this idea through a sequence of his writing distinguishing progress as outcome from progress as instituted process this leads to a deeper issue within this nelsonian theme namely the incompatibility between progress and equilibrium i argue that evolving systems are ordered and coordinated but they are never in equilibrium capitalism is restless it always generates change from within and the proximate source of this progressive tendency is the uneven accumulation of knowledge capitalism is restless because knowledge is restless copyright 2001 by oxford university press

drivers for the use of materials across countries abstract this paper analyses drivers for resource use and material productivity across countries this is not only relevant in light of soaring raw material prices but also because eu policies such as the thematic strategy on the sustainable use of natural resources com 2005 670 the eu raw materials initiative com 2008 699 and various similar policies internationally seek to better manage materials along their life cycle and across economies in order to better understand the system dynamics of material use our paper applies methodologies of material flow analysis and regression analysis to identify the major drivers for resource use and decoupling from gdp drivers are understood as those factors that exert influence on human activities to use resources a panel data set is taken for the european union for the years 1980 2000 eu 15 and 1992 2000 eu 25 the main drivers of resource use were found to be energy efficiency new dwellings and roads construction activities shortcomings of the methodology are also discussed

modelling the transport sector fuel demand for developng economies abstract this paper concentrates on the transport sector of six developing countries with similar common denominators namely turkey thailand pakistan morocco tunisia and malaysia by using standard econometric techniques we analyse the evolution of oil demand for road transport in these countries in relation to independent variables such as income population price of gasoline and diesel etc unlike the treatment in the present literature on the subject gasoline and diesel consumption are estimated separately due to the high share of diesel in the total transport sector consumption on the basis of the estimation over the period 1970 1990 on a country by country basis we forecast the demand for these six countries until 2010 the results of this study indicate that the transport sector will be the driving force for energy and oil demand as part of economic growth in these developing countries its share in the future energy market structure is expected to grow consequently the pricing policies of oil products in this sector have a crucial role for shaping rational economic and energy strategies within the framework of rising environmental concern

the demand for gasoline abstract sufficient time must be allowed to elapse to assess fully the response of gasoline demand to price changes hitherto empirical work on the subject has generally not examined the period beyond 1975 moreover the extant time series studies concentrate almost exclusively on the usa this study extends both the observation period and the country coverage a vehicle stock adjustment model is estimated via its reduced form without explicit consideration of the vehicle stock itself however the estimation procedure incorporates the structure by way of constraints on the parameters cross section analysis offers additional evidence concerning the truly long run price elasticity the results suggest that there is no need to resort to elaborate models to explain adequately gasoline demand gasoline demand exhibits a long run price elasticity near unity with time lags exceeding six years while there is tentative evidence that the duration of these lags is not fixed

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

the uk transport carbon model an integrated life cycle approach to explore low carbon futures abstract current debate focuses on the need for the transport sector to contribute to more ambitious carbon emission reduction targets in the uk various macro economic and energy system wide top down models are used to explore the potential for energy demand and carbon emissions reduction in the transport sector these models can lack the bottom up sectoral detail needed to simulate the effects of integrated demand and supply side policy strategies to reduce emissions bridging the gap between short term forecasting and long term scenario models this paper introduces a newly developed strategic transport energy emissions and environmental impacts model the uk transport carbon model uktcm the uktcm covers the range of transport energy environment issues from socio economic and policy influences on energy demand reduction through to life cycle carbon emissions and external costs the model is demonstrated in this paper by presenting the results of three single policies and one policy package scenario limitations of the model are also discussed developed under the auspices of the uk energy research centre ukerc the uktcm can be used to develop transport policy scenarios that explore the full range of technological fiscal regulatory and behavioural change policy interventions to meet uk climate change and energy security goals

taxation of petroleum products theory and empirical evidence the domestic taxation of petroleum products is an important source of revenue in most countries however there is a wide variation of tax rates on petroleum products across countries which cannot be explained by economic theory alone this paper surveys different considerations advanced for taxing petroleum and presents petroleum tax rate data in 120 countries

the problem of market bias in modern capitalist economies modern societies are presently facing a number of challenging and often contentious issues regarding how to organize and govern a variety of activities that employ a substantial and growing fraction of their resources in certain cases to make market organization work satisfactorily will require strong and fine grained regulation and perhaps a number of other supplementary non market elements for other activities it would be best to rely centrally on other basic organizational modes with markets in an ancillary role in these latter cases too strong an adherence to a belief in the general efficacy of simple market organization can hinder the achievement of a satisfactory solution the central purpose of this essay is to call attention to the complexity and variegation of the sectoral or activityspecific governing structures employed by modern capitalist economies and to argue that such structures need to be tailored to the details of the activities involved copyright 2002 oxford university press

world transport energy demand modelling methodology and elasticities abstract this paper presents the international energy agency s iea approach of modelling transport energy demand fuel demand which is not a demand per se is derived whenever possible from the economic activity in the transport sector and not estimated directly ie using one equation or simultaneous equation system in general the transport models employ a two step approach in the first step transport activity the sector s relevant energy service is estimated econometrically in the second step the transport activity projections are then combined with estimates of efficiency improvements car turnover rates and diesel gasoline penetration assumptions in order to arrive at projections of fuel demand the principal advantages of this approach are that the relevant energy services are modelled and that for model simulation efficiency improvements can be dealt with explicitly the effectiveness of economic instruments is a function of the reaction of consumers and businesses to income and price changes an in depth understanding of income and price elasticities of transport demand and transport energy demand is important in order to be able to assess the effectiveness of policies considered the paper also shows the underlying long term income and price elasticities for oecd and non oecd regions

modelling future private car energy demand in ireland abstract targeted measures influencing vehicle technology are increasingly a tool of energy policy makers within the eu as a means of meeting energy efficiency renewable energy climate change and energy security goals this paper develops the modelling capacity for analysing and evaluating such legislation with a focus on private car energy demand we populate a baseline car stock and car activity model for ireland to 2025 using historical car stock data the model takes account of the lifetime survival profile of different car types the trends in vehicle activity over the fleet and the fuel price and income elasticities of new car sales and total fleet activity the impacts of many policy alternatives may only be simulated by such a bottom up approach which can aid policy development and evaluation the level of detail achieved provides specific insights into the technological drivers of energy consumption thus aiding planning for meeting climate targets this paper focuses on the methodology and baseline scenario baseline results for ireland forecast a decline in private car energy demand growth 0 2 compared with 4 in the period 2000 2008 caused by the relative growth in fleet efficiency compared with activity

entrapment in large technology systems institutional commitment and power relations abstract large technology systems cannot be developed without social commitments usually including legal especially in the form of contracts organisational involving producers users and financiers and political involving various actors associated with the state commitments without such commitments there can be no innovation and no investment given the high risks that are entailed however embedded commitments can create inertia causing inferior technologies and technology paths to survive long after they should have been abandoned this form of technological lock in may be reinforced when there are close relations between producers and states which prevent markets and democratic processes from operating effectively these phenomena are illustrated through study of the thermal oxide reprocessing plant thorp a nuclear reprocessing plant in the uk the lesson for technology policy is that much more attention needs to be given to the maintenance of reversibility and adaptability in infrastructural development

ethically flexible measures of poverty this paper introduces new measures of both relative and absolute poverty using the notion of representative income of a community corresponding to the censored income distribution these new measures satisfy the monotonicity and transfer axioms proposed by sen 1976 in all cases

measuring and forecasting regional environmental and economic efficiency in italy abstractenvironmental and economic efficiency has being receiving growing attention among researchers in general terms this concept is related to the capability of the economic systems to employ natural resources efficiently so as to increase economic and human wealth this clearly implies that both the economic and ecological aspects of decisions ought to be considered bearing this in mind this article considers economic and ecological performance together by applying data envelopment analysis and the malmquist productivity index to investigate the efficiency of the 20 italian regions from 2004 to 2011 the results reveal that the northern regions have been more efficient than the southern ones highlighting the strong geographical differences between the two furthermore this article uses the grey system theory to forecast regional economic and environmental efficiency the results of the forecasting analysis show that the north south duality remains strong and will possibly increase since the r

revisiting the sen poverty index a modification of the official sen poverty index yields an index which is not only continous in individual incomes and consistent with the transfer axiom but also admits a geometric interpretation in terms of the area beneath a graph called the inverse generalized lorenz curve for normalized poverty gaps by jenkins and lambert 1993 or the poverty gap profile by shorrocks 1994

the limits of human development and the use of energy and natural resources the development of nations is an unquestionable requirement a lot of challenges concerning health education and economy are present a discussion on these development models has occupied the minds of decision makers in recent years when energy supply and demand is considered the situation becomes critical and the crucial question is how to improve the quality of life of developing countries based on available models of development that are related to the life style of developed countries for which the necessary use and waste of energy are present how much energy is essential to humanity for not so as to endangering the survival conditions of future generations the human development index hdi establishes the relationship among energy use economic growth and social growth here it can be seen that 75 of the world population has a significant energy consumption potential this is a strong reason to consider that the sustainable development concepts on energy policies are strategic to the future of the planet this paper deals with the importance of seeking alternative development models for human development balance natural resources conservation and environment through rational energy use concepts

projection of future transport energy demand of thailand the objective of this study is to project transport energy consumption in thailand for the next 20 years the study develops log linear regression models and feed forward neural network models using the as independent variables national gross domestic product population and the numbers of registered vehicles the models are based on 20 year historical data between years 1989 and 2008 and are used to project the trends in future transport energy consumption for years 2010 2030 the final log linear models include only gross domestic product since all independent variables are highly correlated it was found that the projection results of this study were in the range of 54 84 59 05 million tonnes of oil equivalent 2 5 times the 2008 consumption the projected demand is only 61 65 of that predicted in a previous study which used the leap model this major discrepancy in transport energy demand projections suggests that projects related to this key indicator should take into account alternative projections because these numbers greatly affect plans policies and budget allocation for national energy management

the dynamic capabilities of firms an introduction an expanded paradigm is needed to explain how competitive advantage is gained and held firms resorting to resource bas ed strategy attempt to accumulate valuable technology assets and employ an aggressive intellectual property stance however winners in the global marketplace have been firms demonstrating timely responsiveness and rapid and flexible product innovation along with the management capability to effectively coordinate and redeploy internal and external competences this source of competitive advantage dynamic capabilities emphasizes two aspects first it refers to the shifting character of the environment second it emphasizes the key role of strategic management in appropriately adapting integrating and re configuring internal and external organizational skills resources and functional competences toward changing environment 3 only recently have researchers begun to focus on the specifics of developing firm specific capabilities and the manner in which competences are renewed to respond to shifts in the business environment the dynamic capabilities approach provides a coherent framework to integrate existing conceptual and empirical knowledge and facilitate prescription this paper argues that the competitive advanis tage of firms stems from dynamic capabilities rooted in high performance routines z operating inside the firm embedded in the firm s processes and conditioned by its history it offers dynamic capabilities as an emerging paradigm of the modern business j firm that draws on multiple disciplines and advances with the help of industry studies in the usa and elsewhere

an analysis of gasoline demand elasticities at the national and local levels in mexico abstract the majority of evidence on gasoline demand elasticities is derived from models based on national data since the largest growth in population is now taking place in cities in the developing world it is important that we understand whether this national evidence is applicable to demand conditions at the local level the aim of this paper is to estimate and compare gasoline per vehicle demand elasticities at the national and local levels in mexico national elasticities with respect to price income vehicle stock and metro fares are estimated using both a time series cointegration model and a panel gmm model for mexican states estimates for mexico city are derived by modifying national estimates according to mode shares as suggested by graham and glaister 2006 and by estimating a panel within groups model with data aggregated by borough although all models agree on the sign of the elasticities the magnitudes differ greatly elasticities change over time and differ between the national and local levels with smaller price responses in mexico city in general price elasticities are smaller than those reported in the gasoline demand surveys a pattern previously found in developing countries the fact that income and vehicle stock elasticities increase over time may suggest that vehicles are being used more intensively in recent years and that mexico city residents are purchasing larger vehicles elasticities with respect to metro fares are negligible which suggests little substitution between modes finally the fact that fuel efficiency elasticities are smaller than vehicle stock elasticities suggests that vehicle stock size rather than its composition has a larger impact on gasoline consumption in mexico city

fuel consumption in road transport a comparative study of china and oecd countries abstract energy conservation and emissions reduction have been the focus of the road transport sector due to its energy intensive and air pollution intensive nature it also embodies the imprints of human technological progress this paper compares the energy consumption of the road transport sector in china and oecd countries we used time series and panel data co integration analysis error correction model and dynamic model to study the impacts of the major influencing factors such as income income structure urbanization price and technological advancement on gasoline and diesel consumption in road transport overall china s fuel consumption is influenced mainly by investment government expenditure and demographic changes such as urbanization while the fuel consumption of oecd countries is mainly driven by household final consumption expenditure in the short run and from a dynamic perspective china s fuel consumption is less influenced by its historical consumption than current influencing factors while that of oecd countries is more affected by historical fuel consumption based on the analysis and findings of this study some policy implications are proposed

towards a theory of the technology based firm abstract the modern firm is a very viable economic institution drawing strength from a competitive market economy with embedded super markets for corporate control and sub markets for internal organization the technology based firm in addition draws strength from its co evolution with modern science and technology and vice versa and thereby becomes increasingly important however received theories of the firm of which there are many have not particularly taken account of technology and technology based firms nor their management this paper takes an empirical point of departure from recent findings regarding the positive relationship between technology diversification on the one hand and corporate growth and business diversification on the other these findings are not readily explainable by received theories of the firm which the paper reviews and the findings are thus taken as an explanandum for a proposed approach to formulate a theory of the technology based firm the approach is compatible with various other theoretical approaches such as the resource based the transaction cost and the evolutionary approach but specifically takes the idiosyncrasies of technology i e technical competence as well as management into account through notably strong economies of scale scope speed and space associated with the combination of different technologies and resources the technology based firm is subjected to specific dynamics in its growth and diversification and shifts of businesses and resources in particular a technology based firm tends to engage in technology diversification thereby becoming multitechnological as such the technology based firm has incentives to economize on increasingly expensive new technologies by pursuing strategies of internationalization on both input and output markets technology related business diversification external technology marketing and sourcing r d rationalization and technology related partnering

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

validating energy oriented cge models although cge models have received heavy usage they are often criticized as being insufficiently validated key parameters are often not econometrically estimated and the performance of the model as a whole is rarely checked against historical outcomes as a consequence questions frequently arise as to how much faith one can put in cge results in this paper we employ a novel approach to the validation of a widely utilized global cge model gtap e by comparing the variance of model generated petroleum price distributions driven by historical demand and supply shocks to the model with observed five year moving average price distributions we conclude that energy demand in gtap e is far too price elastic over this time frame after incorporating the latest econometric estimates of energy demand and supply elasticities we revisit the validation question and find the model to perform more satisfactorily as a further check we compare a deterministic global general equilibrium simulation based on historical realizations over the 2001 2006 period during which petroleum prices rose sharply along with growing global energy demands as anticipated by the stochastic simulations the revised model parameters perform much better than the original gtap e parameters in this global general equilibrium context

catastrophic medical expenditure risk we propose a measure of household exposure to particularly onerous medical expenses the measure can be decomposed into the probability that medical expenditure exceeds a threshold the loss due to predictably low consumption of other goods if it does and the further loss arising from the volatility of medical expenses above the threshold depending on the choice of threshold the measure is consistent with a model of reference dependent utility with loss aversion unlike the risk premium the measure is only sensitive to particularly high expenses and can identify households that expect to incur such expenses and would benefit from subsidised but not actuarially fair insurance an empirical illustration using data from seven asian countries demonstrates the importance of taking account of informal insurance and reveals clear differences in catastrophic medical expenditure risk across and within countries in general risk is higher among poorer rural and chronically ill populations

on the watts multidimensional poverty index and its decomposition summary the multidimensional extension of the watts poverty index may be expressed as a function of five determinants measuring respectively the impacts of what are defined in the paper as the watts poverty gap ratio the theil bourguignon index of inequality among the poor the overall headcount ratio the weights of the various dimensions and some measure of correlation between the various dimensions using the shapley decomposition we apply this index to world data on the per capita gdp life expectancy and literacy rates and derive the contributions of the five determinants defined above to the variation of this index during 1993 2002

distinguished lecture on economics in government the private uses of public interests incentives and institutions as a long time student of the public sector i welcomed the opportunity to come to washington as a member of the council of economic advisers and later to become the chairman of the council partly because it gave me an opportunity to study at first hand this immensely important part of our economy and society and to test my ideas against the reality of government in action to be sure i came also as an activist if not with a fully articulated agenda at least with a view about what it was that government should and should not be doing my reference point was the fundamental theorems of welfare economics which as some describe them proved that the market left to itself would produce efficient allocations many saw in these theorems the vindication of adam smith s faith in the invisible hand leading the self interested decisions of each person to maximize the well being of the nation as a whole today many of us look at the fundamental theorem not as a description of the world but as an explication of the conditions under which a market equilibrium will be pareto efficient these conditions are quite strong the importance of some of the more explicit assumptions like the lack of externalities and the completeness of markets has long been known in the last two decades we have explored much more seriously the consequences of the informational assumptions implicit in the belief that markets are efficient in particular it has been shown that in the presence of imperfect information or incomplete markets the economy will not be pareto efficient in other words there joseph stiglitz is senior vice president and chief economist world bank washington d c stiglitz was a member of the council of economic advisers from 1993 95 and chairman

review of key international demand elasticities for major industrializing economies abstract this paper conducts a selective review of various estimates for energy demand responses focused specially upon lower income industrializing economies rather than richer mature nations it emphasizes recent trends from empirical studies that have been published after 2000 emphasis is placed on the five major emerging or transitional economies in brazil china india mexico and russia although other important nations like chile and south korea are also discussed when studies are available the review focuses attention on the long run responses to changes in prices and income after capital stock turnover has been completed the terminology often refers to elasticities or the percentage change in energy use divided by the percentage change in price or income holding constant all other factors that could influence energy use decisions estimates cover petroleum products natural gas and electricity although the available studies often ignore coal they also include the economy wide impacts real gdp to price changes most studies have focused upon household and transportation use of liquid fuels many fewer studies have investigated fuels used by industry or commerce or for electric generation based upon the available estimates price and income elasticities for liquid fuels are generally less than one unity for many countries and sectors except for the long run income effect for transportation purposes which can range widely by country between 0 24 and 1 75 while averaging 0 94 for all countries

linking material and energy flow analyses and social theory the paper explores the potential of habermas theory of communicative action to alter the social reflexivity of material and energy flow analysis with his social macro theory habermas has provided an alternative critical justification for social theory that can be distinguished from economic libertarianism and from political liberalism implicitly most flow approaches draw from these theoretical traditions rather than from discourse theory there are several types of material and energy flow analyses while these concepts basically share a system theoretical view they lack a specific interdisciplinary perspective that ties the fundamental insight of flows to disciplinary scientific development instead of simply expanding micro models to the social macro dimension social theory suggests infusing the very notion of flows to the progress of disciplines with regard to the functional integration of society material and energy flow analyses can rely on the paradigm of ecological economics and at the same time progress the debate between strong and weak sustainability within the paradigm however placing economics at the centre of their functional analyses may still ignore the broader social integration of society depending on their pre analytic outline of research and the methods used

eco efficiency as abandonment of nature abstract the paper argues that eco efficiency is fundamentally disruptive when promoted as a universal prescription for environmental policy eco efficiency runs against the cognitive and institutional bases of sustainable human environmental interaction at the cognitive level eco efficiency assumes that an individual s concern for the environment can be decoupled from his or her material dependency on ecosystem services at the collective level eco efficiency builds upon decoupling environmental governance from the local socio economic and cultural context the assumptions are not well supported by empirical work on systems of human environmental interaction which stresses the importance of material connections to maintaining environmental concerns the criterion for adopting eco efficiency should be the extent to which it promotes the recoupling of human perception of environmental issues with human action on the environment and the concomitant recoupling of collective local organization with locally crafted ecosystem management

values ideology and politics in ecological economics abstract ecological economics is built on a value commitment to study environmental issues and to contribute constructively to a more sustainable development path however many ecological economists still hesitate it appears to depart too much from other scholars by openly addressing issues of values and ideology in this essay the role of the scholar s orientation with respect to values and ideology is addressed it is observed that not only scholars but also actors in society are guided by their ideological orientation this leads to the idea that some of the weaknesses of economic man and profit maximising firm assumptions can be mitigated by introducing a political economic person and a political economic organisation

analysing gasoline demand elasticities a survey this paper is a survey of studies on gasoline demand although there are very many dxerent studies in this eld which sometimes appear to arrive at contradictory results we find that with proper stratification of studies by model and data type much of the contict turns to consensus in this survey we classtfy studies by data type and by ten d erent categories of model and with the exception of estimates on seasonal data which tend to be unstable and of certain inappropriate model formulations we find a fair degree of agreement concerning average short run and even long run income and price elasticities

dynamic poverty decomposition analysis an application to the philippines summary in this paper we propose a new method of poverty decomposition our method remedies the shortcomings of existing methods and has some desirable properties such as time reversion consistency and subperiod additivity our decomposition integrates the existing methods of growth redistribution decomposition and sector based decomposition because it allows us to decompose the change in poverty into growth and redistribution components for each group e g regions or sectors in the economy our decomposition works well in cases where only partial data are available for some periods it is also flexible and can be extended to have the following six components population shift within region redistribution between region redistribution nominal growth inflation and methodological change components the empirical application of the six way decomposition to the philippines for the period 1985 2009 shows that important policies for poverty reduction may differ across regions for example the autonomous region in muslim mindanao would need growth enhancing policies whereas eastern visayas would need policies to improve the income distribution our decomposition method has a wide applicability and may complement the poverty profile approach

cognitive and institutional perspectives of eco efficiency the paper sketches out a theoretical framework for analysing the interplay between eco efficiency cognition and institutions it derives from analytical shortfalls of the prevailing literature which features strongly engineering and business economics by using insights from new institutional economics from cognitive science and partly from evolutionary economics it emphasises the role cognition and institutions play in the adoption of green technologies by firms a cognitive perspective derives from recent research on simple heuristics and context based rationality it is proposed that those findings can serve to analyse decision making of individual actors respectively firms and thus should complement economic analysis a second proposition is that eco efficiency and normative rules such as a factor four strongly rely upon institutions i e the ability of institutions to evolve over time and the development of those institutions that are most appropriate to enhance technological change in this regard business institutions and competition are crucial but regulatory needs remain in order to safeguard continuity of knowledge creation the framework allows for an analysis why overall adoption of eco efficiency still can be considered relatively slow and why some markets and firms are far ahead as a brief case study the article reflects upon german waste law s ability to enhance eco efficiency

estimating the demand for gasoline in developing countries senegal abstract this paper estimates the aggregate demand for gasoline in senegal from 1970 to 2008 the long term and short term elasticities of demand with respect to gasoline prices and income are of paramount interest in this study in senegal rising food prices unemployment and shortage of electric supply are always associated with the spiking cost of world oil prices to understand the external shocks of world oil price and demand for gasoline in senegal this study tested a log linear model against the linear model of the demand for oil function with lagged dependent variables as an explanatory variable here the linear specification of the demand for oil is rejected in this study in favor of the log linear the natural log transformation is typical when using high frequency data and significantly reduces skewness and kurtosis generally in this study i found that short run elasticity is smaller than long run elasticity and gasoline demand is inelastic with respect to both price and income for both the short and long runs in senegal this is why researcher like moosa posits that this assertion can be rationalised on the grounds that oil is such an important commodity that does not have close substitutes at least for its uses 1998 p 3

issues in measuring and modeling poverty economists have relied heavily on household incomes or expenditures normalized for differences in household specific prices and demographics in their research and policy advice related to poverty and inequality recognizing the conceptual and empirical problems that confound such measures does not mean that they should be ignored instead it indicates the need for supplementary measures to capture the missing items implementing a genuinely multidimensional approach will often make the welfare rankings of social states more difficult but that fact points to the nonrobustness of low dimensional rankings this may have its own policy ramifications with the possibility of correspondence between policy instruments and welfare objectives the model types used to understand the poverty and inequity determination processes will be affected not only will there be more dependent variables to consider but variables will have potentially complex relationships these relationships will often be hard to empirically disentangle despite richer integrated and longitudinal data sets such data open rich and relevant agenda for research into the dynamics of poverty along multiple dimensions a simultaneous attack on these issues from all three fronts measurement modeling and data offers hope of establishing a credible empirical foundation for public action in fighting poverty

recent evolutionary theorizing about economic change this famous passage from marshall s principles of economics it first appeared in the fifth edition which came out in 1907 nicely brings out two issues which are as germane to economics today as they were when marshall wrote the first is the heavy reliance by economists in their formal theorizing on the notion of equilibrium the other is the appeal that biological conceptions3x201d have for many economists particularly when their focus is on economic change

equity regarding poverty measures differences in needs and the role of equivalence scales the paper investigates the definition of equity regarding poverty measures when there are different household types in the population it demonstrates the implications of a between type regressive transfer principle for poverty measures for the choice of poverty lines and for the measurement of living standard the role of equivalence scales which are popular in empirical work on poverty measurement is clarified ce memoire examine la definition de mesures de pauvrete fondees sur l equite quand existent differents types de menages dans la population on montre les implications d un principe de transfert regressif entre types de menages pour les mesures de pauvrete pour la definition des seuils de pauvrete et pour la mesure du niveau de vie on clarifie le role des echelles d equivalence qui sont d un usage generalise dans les travaux sur la mesure de la pauvrete

gender and multidimensional poverty in nicaragua an individual based approach most existing empirical papers concerned about multidimensional poverty use the household as the unit of analysis so that the multidimensional poverty status of the household is equated with the multidimensional poverty status of all its members this assumption ignores intra household inequalities additionally households containing both a female and a male cannot contribute to a gender gap in poverty so gender differentials in poverty cannot be estimated but the sustainable development goals have put special emphasis on gender equality therefore new measures able to capture the gender differences are needed consequently in this paper we propose an individual based multidimensional poverty measure in order to estimate the three i s of multidimensional poverty incidence intensity and inequality in nicaragua as well as the gender differentials we also estimate logit regressions to better understanding the determinants of multidimensional poverty in this country overall we find that there are statistically significant gender differences in multidimensional poverty in nicaragua but they are estimated to be small and lower than 5 however the gender differential in inequality is larger than 10 and it suggests that multi dimensionally poor women are living in very intense poverty when compared with multi dimensionally poor men we also find that the elderly and children are the most vulnerable people in terms of multidimensional poverty in this country furthermore when information on employment domestic work and social protection is considered in the analysis the gender gaps become more substantial and women are more likely to be poor than men

the dynamic implications of increasing returns technological change and path dependent inefficiency this paper addresses the issue of path dependent selection and inefficiency counterfactual methods and the empirical evidence employed in this research trajectory the general message is basically that the theoretical argument to prove path dependent inefficiency is relatively straightforward while empirical demonstrations as well as the analysis of welfare implications are much more difficult in the first section we briefly state the basic argument explaining how localized learning leads to an incomplete exploration of the variety distribution of a technology we then synthesize the most interesting historical studies which get potential regret results and ask whether these results suggest a large welfare loss to try to answer this question we start from the critical arguments of liebowitz and margolis to discuss the theoretical and empirical difficulties of establishing path dependent inefficiency
