estimating residential demand for electricity in greece abstract this paper examines the residential demand for electricity in greece the issues of structural stability price and income sensitivity of both long and short run residential demand for electricity in greece were examined employing monthly data over the period 1986 1999 the long run residential demand for electricity is estimated taking into account changes in weather conditions weighted by the size of the population employing multivariate framework analysis a long run residential demand function for electricity sensitive to real income price level and weather conditions is found to exist and the importance of short run deviations is presented using vector error correction model vecm estimation the empirical evidence suggests the presence of a stable residential demand for electricity in greece both in the long and short run periods and the policy implications of such a relationship are presented

convergence in adaptation to climate change evidence from high temperatures and mortality 1900 2004 author s barreca a clay k deschenes o greenstone m shapiro js abstract this paper combines panel data on monthly mortality rates of us states and daily temperature variables for over a century 1900 2004 to explore the regional evolution of the temperature mortality relationship and documents two key findings first the impact of extreme heat on mortality is notably smaller in states that more frequently experience extreme heat second the difference in the heat mortality relationship between hot and cold states declined over 1900 2004 though it persisted through 2004 continuing differences in the mortality consequences of hot days suggests that health motivated adaptation to climate change may be slow and costly around the world

the impact of climate on the law of one price a test using north american food prices from the 1920s using grocery price data for over 100 urban locations across the us and canada from the 1920s we show that deviations from the law of one price lop were strongly related to climate differences the effect of climate has a large impact on the elasticity of deviations from lop with respect to distance while having no impact on the border effect we then test a counterfactual to show that the relationship between deviations from lop and temperature does not hold when historical temperature data are replaced with contemporary this is evidence that climate impacts production l impact du climat sur la loi du prix unique un test utilisant les prix de la nourriture en amerique du nord dans les annees 1920 a l aide de donnees sur les prix de la nourriture dans les epiceries dans plus d une centaine de villes aux etats unis et au canada dans les annees 1920 on montre que les deviations par rapport a la loi du prix unique lpu sont fortement reliees aux differences dans le climat l effet du climat a un grand impact sur l elasticite des deviations par rapport a la lpu par rapport a la distance mais aucun impact sur l effet de frontiere on utilise alors un test contrefactuel pour montrer que la relation entre les deviations par rapport a la lpu et la temperature ne tient pas quand on remplace les temperatures historiques par les temperatures contemporaines ceci montre que le climat a un impact sur la production

forecasting residential electricity consumption in greece using monthly and quarterly data abstract this paper studies electricity consumption household use only in greece we explore the dynamic relationships among several potentially relevant time series variables and develop appropriate models for forecasting it is apparent that personal disposable income temperature and the price of electricity used by the households play an important role in the demand for electricity in this study we use both monthly and quarterly data and find that the performance of quarterly models may not be as good as that of the monthly ones for transfer function model identification we use the linear transfer function ltf method which is more efficient and easier to use than the traditional cross correlation ccf method

electricity demand response to price changes the portuguese case taking into account income differences abstract in this paper we study the behavior of electricity use in portuguese households using microdata from five independent surveys our sample covers the period from 1989 to 2010 which was characterized by major changes in the country we adopt the pseudo panel methodology creating 350 cohorts based on the size of the household the type of location rural or urban the region and the income quintile our results show relatively high medium long run own price elasticities indicating that an increase in the electricity price due to for instance policy intervention would in fact decrease electricity use cross price elasticities indicate that electricity and gas are substitutes additionally the income quintiles analysis shows significant differences in the elasticities depending on the income group hence political interventions in the electricity sector may have important redistributive effects

adaptation to climate change a review through a development economics lens abstract this paper looks at adaptation to climate change from the point of view of poor households since the development literature has firmly established the role of weather risk as a source of income volatility for the poor and climate change is expected to increase this risk we review the range of risk coping mechanisms available to poorer households with a focus on possible barriers to adaptation we ask both how government interventions affect the set of options available for adaptation and risk coping and also what these adaptive responses imply for the prospects of sustainable development support for adaptation can involve efforts to make existing locations livelihoods and forms of production more resilient to climate risk in situ adaptation or reductions in vulnerability through the geographical and sectoral mobility of the poor transformational adaptation our review shows how successful adaptation will need to strike a balance between the two forms of adaptation avoiding locking in unsustainable practices in locations that are already marginal from an economic perspective and taking account of broader socio economic trends already taking place in many developing countries such as population growth and urbanisation we also highlight important considerations for policy makers which to date have been relatively neglected in the literature in particular related to the dynamic interaction between adaptation and sustainable development

witchcraft weather and economic growth in renaissance europe between the thirteenth and nineteenth centuries as many as one million individuals in europe were executed for the crime of witchcraft the majority of the trials and executions took place during the sixteenth and seventeenth centuries during this period the speed and volume of executions were astonishing in one german town as many as 400 people were killed in a single day midelfort 1972 the trials were ubiquitous conducted by both ecclesiastical and secular courts by both catholics and protestants the victims were primarily women primarily poor and disproportionately widows the persecutions took place throughout europe starting and ending earlier in southwest europe than in the northern and eastern areas and spread even across the atlantic ocean to salem massachusetts although witchcraft trials in europe and america largely ended by the late eighteenth century witchcraft accusations and killings still take place in many countries today particularly in the developing world for example witchcraft is often blamed for aids deaths in sub saharan africa ashforth 2001 and miguel 2003 shows that negative economic shocks are associated with increases in witch killing in modern tanzania belief in the witch and fear of her is enduring while much work has been done on the motivations behind the european trials the large scale causes remain unknown the existing work has primarily been concerned with the factors that played into trials on a small scale why a certain individual was targeted or why a certain type of individual was targeted in a given area this work has indicated that there was a diverse set of issues that played into trials on an individual level more broadly however there are few causal explanations for why witchcraft trials happened at all and on such a large scale in so many

shutting down the thermohaline circulation past climatic changes were caused by a slowdown of the thermohaline circulation we use results from experiments with three climate models to show that the expected cooling due to a slowdown of the thermohaline circulation is less in magnitude than the expected warming due to increasing greenhouse gas concentrations the integrated assessment model fund and a meta analysis of climate impacts are used to evaluate the change in human welfare we find modest but by and large positive effects on human welfare since a slowdown of the thermohaline circulation implies decelerated warming

modeling climate feedbacks to electricity demand the case of china this paper is an empirical investigation of the effects of climate on the use of electricity by consumers and producers in urban and rural areas within china it takes advantage of an unusual combination of temporal and regional data sets in order to estimate temperature as well as price and income elasticities of electricity demand the estimated positive temperature electric power feedback implies a continually increasing use of energy to produce electric power which in china is primarily based on coal in the absence of countervailing measures this will contribute to increased emissions increased atmospheric concentrations of greenhouse gases and increases in greenhouse warming

structural changes in residential electricity demand abstract the purposes of this study are to investigate the structural changes in residential electricity demand parameters and explain the causes for such changes a dynamic model is specified and estimated using pooled time series and cross section state level data for the usa changes in demand parameters over time are examined by using successive over lapping ten year sample periods for data from 1955 78 for parameter estimation the results show that there have been significant structural changes in demand elasticities for several independent variables these changes can be best explained by changes in household stocks of major electric appliances as new technologies have been developed improved and ingrained in consumer lifestyles and preference functions over time further inquiry shows no strong evidence of structural changes associated with either the reversal of the declining trend of electricity prices or the 1973 oil embargo however more data after the oil embargo may be needed to validate the existence of price asymmetries in electricity demand

dynamics of urban land use sequential location of an office firm and residence abstract the objective of this paper is to depict the transition in the land use pattern of the suburbanization of workers and the concentration of business firms by considering a sequential entry of a firm and its worker who minimize the total cost under monopsony in the land market the equilibrium development process of the urban land use pattern under a height restriction is derived it is shown that the first replacement of a residence with a firm always takes place at an intermediate location and successive replacements take place inwardly with alternations of right and left and then outward replacements begin when the height regulation is removed the equilibrium density function of firms is shown to be a duocentric cosine truncated curve symmetrical with respect to the city center and the equilibrium density function of residence is linear it is also demonstrated that the optimum density distribution of the firms and the workers becomes identical to the equilibrium distribution except for a difference in a parameter value and that the optimum central business district cbd and city lengths are shorter than the equilibrium cbd and city lengths respectively

climate change and birth weight there is a growing consensus that emissions of greenhouse gases due to human activity will alter the earth s climate most notably by causing temperatures precipitation levels and weather variability to increase the design of optimal climate change mitigation policies requires estimates of the health and other benefits of reductions in greenhouse gases current evidence on the magnitude of the direct and indirect impacts however is considered insufficient for reliable conclusions a j mcmichael et al 2003 1 in addition to the overall predicted warming trend one important feature of many global climate change forecasts is an increased incidence of very high and low temperatures to provide evidence of the potential benefits of greenhouse gas reductions this paper documents whether the temperature variation predicted to be part of climate change including extreme high and low temperatures historically has had negative health consequences through its effect on babies while in utero using individual level data on more than 37 1 million births we find that exposure to extreme hot temperatures during pregnancy leads to lower birth weight we combine this

a model of residential demand for electricity using a national household sample abstract using a three equation model demand price appliance stock index and a current national household data set this study develops partial and total elasticity estimates for the usa partial elasticities are 0 102 for income and 0 193 for price while total elasticities are 0 410 for income and 1 403 for price

the demand for residential electricity in south africa abstract this paper examines the residential demand for electricity in south africa as a function of real gross domestic product per capita and the price of electricity during the period 1978 2005 we make use of the bounds testing approach to cointegration within an autoregressive distributed framework suggested by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 3 289 326 following the literature we use a linear double logarithmic form using income and price as independent variables in the empirical analysis in the long run we find that income is the main determinant of electricity demand while electricity price is insignificant

climate change policy what do the models tell us very little a plethora of integrated assessment models iams have been constructed and used to estimate the social cost of carbon scc and evaluate alternative abatement policies these models have crucial flaws that make them close to useless as tools for policy analysis certain inputs e g the discount rate are arbitrary but have huge effects on the scc estimates the models produce the models descriptions of the impact of climate change are completely ad hoc with no theoretical or empirical foundation and the models can tell us nothing about the most important driver of the scc the possibility of a catastrophic climate outcome iam based analyses of climate policy create a perception of knowledge and precision but that perception is illusory and misleading jel c51 q54 q58

economic determinants of land invasions this study estimates the effect of economic conditions on redistributive conflict we examine land invasions in brazil using a panel data set with over 50 000 municipality year observations adverse eco nomic shocks instrumented by rainfall cause the rural poor to invade and occupy large landholdings this effect exhibits substantial heterogeneity by land inequality and land tenure systems but not by other observable variables in highly unequal municipalities negative income shocks cause twice as many land invasions as in municipalities with average land inequality cross sectional estimates using fine within region variation also suggest the importance of land inequality in explaining redistributive conflict i introduction c onflict over land is endemic to many rural econo mies in environments marked by a highly skewed distribution of property incomplete land and credit markets poorly or unevenly enforced property rights and weak political institutions agents often resort to extralegal means to improve their economic positions the poor frequently invade private properties and occupy them until either forcibly expelled or granted official titles land conflict which is prevalent in many countries such as brazil south africa uganda and venezuela may distort the allocation of resources in the agricultural sector away from productive uses and thereby contribute to the persistence of rural poverty how do economic conditions affect this redistrib utive conflict this paper explores this question using a rich municipal level data set of 5 299 land invasions from 1988 to 2004 in brazil we follow miguel satyanath and sergenti 2004 by using rainfall as a source of exogenous variation to study the relationship between income and conflict and we find that adverse economic shocks cause the rural poor to invade large landholdings this effect exhibits considerable het erogeneity by land inequality and land tenure systems in highly unequal municipalities negative income shocks cause twice as many land invasions as in municipalities with average land inequality the effect of income shocks is even stronger in highly polarized municipalities as measured by the degree of bimodality in the land distribution cross sectional estimates using fine within region variation also suggest the importance of land inequality in explaining redistributive conflict we also find that income shocks cause significantly more land invasions in municipalities with a greater proportion of land under fixed rent contracts by contrast we find no evidence of heterogeneity on a range of other political and socioeconomic variables including political competition sharecropping police expenditures and social welfare spending recent microeconometric studies have examined two

humanitarian crises and adolescent well being knowledge gaps and prospects adolescence constitutes the second and final window of human growth and a period of specific vulnerabilities such as early pregnancy early marriage hiv infection suicide violence alcohol and drugs only a limited body of research investigates the effects of humanitarian crises on the human capital and well being of adolescents the evidence focuses on the short term effects of conflict and to a lesser extent natural disasters on education physical health and nutrition but not on mental health most analyses examine the situations of individuals exposed in utero and young childhood but rarely during adolescence typically missing are robust empirical identification strategies and estimates on heterogeneous effects across age or gender the lack of quality data and challenges in defining adolescence establishing causality or ensuring ethical research explain the knowledge gaps possible ways to expand the evidence base include mixing georeferenced data on individual location with georeferenced data on crises sharpening quasi experimental analytical techniques and reconsidering the current timing of demographic data collection now spanning 4 or 5 year intervals the failure to make such adjustments will end by ignoring specific vulnerabilities among adolescents and render sustainable progress in well being globally narrowing inequalities and guaranteeing human rights to all more difficult to achieve

clearing the air the effects of gasoline content regulation on air quality this paper examines the effects of u s gasoline content regulations on groundlevel ozone pollution these regulations are costly and have been shown to fragment gasoline markets and raise prices paid by consumers we provide the first comprehensive empirical estimates of the regulations air quality benefits we exploit the fact that gasoline regulations vary by time and place of introduction using both difference in difference and regression discontinuity designs we show that federal regulations targeting the emissions of volatile organic compounds vocs one of the two main precursors to ozone do not substantially improve air quality this outcome is driven by the response of refiners to the regulation minimizing the cost of abatement involves removing a type of voc from gasoline that is not an important determinant of ozone pollution in california however we show that precisely targeted regulations requiring the removal of vocs particularly prone to forming ozone caused a significant improvement in air quality

policy analysis of the greenhouse effect an application of the page model abstract in this paper we introduce a comprehensive model for policy analysis of the greenhouse effect page we apply the page model to assess the merits of policies to prevent global warming by controlling the emissions of greenhouse gases and policies to adapt to any global warming that occurs the results confirm that it is difficult to overcome the problem of global warming by taking preventive action alone the argument for introducing an aggressive adaptive policy is very strong we calculate the valuation that would have to be placed upon non economic environmental and social impacts for a combined strategy of preventive and adaptive policies to be considered a worthwhile option both for individual regions and for the world as a whole we also show that uncertainties in all four groups of inputs to the model scientific costs of control costs of adaptation and valuation of impacts have a great influence on the costs and impacts of the combined strategy

environment health and human capital in this review we discuss three major contributions economists have made to our understanding of the relationship between the environment and individual well being first in explicitly recognizing how optimizing behavior particularly in the form of residential sorting can lead to nonrandom assignment of pollution economists have employed a wide range of quasi experimental techniques to develop causal estimates of the effect of pollution second economic research has placed a considerable focus on the role of avoidance behavior which is an important component for understanding the difference between biological and behavioral effects of pollution and for proper welfare calculations lastly economic research has expanded the focus of analysis beyond traditional health outcomes to include measures of human capital including labor supply productivity and cognition our review of the quasi experimental evidence on this topic suggests that pollution does indeed have a wide range of effects on individual well being even at levels well below current regulatory standards given the importance of health and human capital as an engine for economic growth these findings underscore the role of environmental conditions as an important factor of production jel i12 i31 j24 q51 q53

climate shocks and exports this paper uses international trade data to examine the effects of climate shocks on economic activity we examine panel models relating the annual growth rate of a country s exports in a particular product category to the country s weather in that year we find that a poor country being 1 degree celsius warmer in a given year reduces the growth rate of that country s exports by between 2 0 and 5 7 percentage points with no detectable effects in rich countries we find negative effects of temperature on exports of both agricultural products and light manufacturing products with little apparent effects on heavy industry or raw materials the results confirm large negative effects of temperature on poor countries economies and suggest that temperature affects a much wider range of economic activity than conventionally thought this abstract was borrowed from another version of this item

the structure of residential energy demand in greece abstract this paper attempts to shed light on the determinants of residential energy demand in greece and to compare it with some other oecd countries from the estimates of the short run and long run elasticities of energy demand for the period 1965 1999 we find that residential energy demand appears to be price inelastic also we do not find evidence of a structural change probably because of the low efficiency of the energy sector we find however that the magnitude of the income elasticity varies substantially between greece and other oecd countries

tail hedge discounting and the social cost of carbon the choice of an overall discount rate for climate change investments depends critically on how different components of investment payoffs are discounted at differing rates reflecting their underlying risk characteristics such underlying rates can vary enormously from 1 percent for idiosyncratic diversifiable risk to 7 percent for systematic nondiversifiable risk which risk adjusted rate is chosen can have a huge impact on cost benefit analysis in this expository paper i attempt to set forth in accessible language with a simple linear model what i think are some of the basic issues involved in discounting climate risks the paper introduces a new concept that may be relevant for climate change discounting the degree to which an investment hedges against the bad tail of catastrophic damages by insuring positive expected payoffs even under the worst circumstances the prototype application is calculating the social cost of carbon jel c51 q54 q58

electricity demand for south korean residential sector abstract this study estimates the electricity demand function for the residential sector of south korea with the aim of examining the effects of improved energy efficiency structural factors and household lifestyles on electricity consumption in the study time series data for the period from 1973 to 2007 is used in a structural time series model to estimate the long term price and income elasticities and annual growth of underlying energy demand trend uedt at the end of the estimation period the result shows a long term income elasticity of 1 33 and a long term price elasticity of 0 27 with 0 93 as the percentage growth of uedt at the end of the estimation period this result suggests that in order to encourage energy efficiency in the residential sector the government should complement the market based pricing policies with non market policies such as minimum energy efficiency standards and public enlightenment

will u s agriculture really benefit from global warming accounting for irrigation in the hedonic approach will u s agriculture really benefit from global warming accounting for irrigation in the hedonic approach wolfram schlenker w michael hanemann and anthony c fisher there has been a lively debate about the potential impact of global climate change on u s agriculture most of the early agro economic studies predict large damages see for example richard m adams 1989 harry m kaiser et al 1993 and adams et al 1995 in an innovative paper robert mendelsohn william d nordhaus and daigee shaw 1994 hereafter mns propose a new approach using the variation in temperature and precipitation across u s counties to estimate a reduced form hedonic equation with the value of farmland as the dependent variable a change in temperature and or precipitation is then associated with a change in farmland value which can be interpreted as the impact of climate change adams et al 1998 characterize the hedonic approach as a spatial analogue approach and acknowledge that the strength of the spatial analogue approach is that structural changes and farm responses are implicit in the analysis freeing the analyst from the burden of estimating the e ects of climate change on particular region speci c crops and farmer responses on the other hand one of the potential disadvantages of the hedonic approach is that it is a partial equilibrium analysis i e agricultural prices are assumed to remain constant 1 while year to year uctuations in annual weather conditions certainly have the potential to impact current commodity prices especially for crops produced only in a relatively localized area such as citrus fruits which are grown mainly in california and florida changes in long run weather patterns i e changes in climate might have a smaller e ect on commodity prices because of the greater potential for economic adaptation particularly shifts in growing regions 2 the hedonic approach as implemented by mns predicts that existing agricultural land on average might be more productive and hence result in bene ts for u s farmers 3 the hedonic approach has received considerable attention in our judgment in part because the conclusions are at variance with those of some other studies

how do urban households in china respond to increasing block pricing in electricity evidence from a fuzzy regression discontinuity approach abstract china is the largest electricity consumption country after it has passed the united states in 2011 residential electricity consumption in china grew by 381 35 12 85 per annum between 2000 and 2013 in order to deal with rapid growth in residential electricity consumption an increasing block pricing policy was introduced for residential electricity consumers in china on july 1st 2012 using difference in differences models with a fuzzy regression discontinuity design we estimate a causal effect of price on electricity consumption for urban households during the introduction of increasing block pricing policy in guangdong province of china we find that consumers do not respond to a smaller approximately 8 increase in marginal price however consumers do respond to a larger increase in marginal price an approximately 40 increase in marginal price induces an approximately 35 decrease in electricity use 284 kw h per month our results suggest that although the increasing block pricing could affect the behavior of households with higher electricity use there is only a limit potential to overall energy conservation

on modeling and interpreting the economics of catastrophic climate change with climate change as prototype example this paper analyzes the implications of structural uncertainty for the economics of low probability high impact catastrophes even when updated by bayesian learning uncertain structural parameters induce a critical tail fattening of posterior predictive distributions such fattened tails have strong im plications for situations like climate change where a catastrophe is theoretically possible because prior knowledge cannot place sufficiently narrow bounds on overall damages this paper shows that the economic consequences of fat tailed structural uncertainty along with unsureness about high temperature damages can readily outweigh the effects of discounting in climate change policy analysis

the impact of global warming on agriculture a ricardian analysis reply we measure the economic impact of climate on land prices using cross sectional data on climate farmland prices and other economic and geophysical data for almost 3 000 counties in the united states we find that higher temperatures in all seasons except autumn reduce average farm values while more precipitation outside of autumn increases farm values applying the model to a global warming scenario shows a significantly lower estimated impact of global warming on u s agriculture than the traditional production function approach and in one case suggests that even without co sub 2 fertilization global warming may have economic benefits for agriculture 16 refs 5 figs 5 tabs

the enduring impact of the american dust bowl short and long run adjustments to environmental catastrophe the 1930 s american dust bowl was an environmental catastrophe that greatly eroded sections of the plains analyzing new data collected to identify low medium and high erosion counties the dust bowl is estimated to have immediately substantially and persistently reduced agricultural land values and revenues during the depression and through at least the 1950 s there was limited reallocation of farmland from activities that became relatively less productive agricultural adjustments such as reallocating land from crops to livestock recovered only 14 to 28 of the initial agricultural cost the economy adjusted predominately through migration rather than through capital inows and increased industry

socially optimal and equilibrium distributions of office activity models with exogenous and endogenous contacts abstract two models of the location of office activities within a city are developed in the first model the pattern of interoffice contacts is specified exogenously as has been traditional in the literature in the second model the contact patterns as well as the distribution of firms are endogenous for both models the market equilibrium distribution of office activities is not socially optimal two sources for this market failure are identified in these models 1 agglomeration economies and 2 transactional externalities arising from firm interdependence and mobility

residential electricity demand in spain new empirical evidence using aggregate data this paper presents an empirical analysis on residential demand for electricity this analysis has been performed using aggregate panel data at the province level for 47 spanish provinces for the period from 2000 to 2008 for this purpose we estimated a log log demand equation for electricity consumption using a dynamic partial adjustment approach this dynamic demand function has been estimated using a two step system gmm estimator proposed by blundell and bond 1998 the purpose of this empirical analysis is to highlight some of the characteristics of spanish residential electricity demand particular attention has been paid to the influence of price income and weather conditions on electricity demand the estimated short and long run own price elasticities are negative as expected but lower than 1 furthermore weather variables have a significant impact on electricity demand

why the far distant future should be discounted at its lowest possible rate abstract a critical feature of the distant future is currently unresolvable uncertainty about what will then be the appropriate rate of return on capital to use for discounting this paper shows that there is a well defined sense in which the lowest possible interest rate should be used for discounting the far distant future part of any investment project some implications are discussed for evaluating long term environmental projects or activities like measures to mitigate the possible effects of global climate change

the structure of economic modeling of the potential impacts of climate change grafting gross underestimation of risk onto already narrow science models scientists describe the scale of the risks from unmanaged climate change as potentially immense however the scientific models because they omit key factors that are hard to capture precisely appear to substantially underestimate these risks many economic models add further gross underassessment of risk because the assumptions built into the economic modeling on growth damages and risks come close to assuming directly that the impacts and costs will be modest and close to excluding the possibility of catastrophic outcomes a new generation of models is needed in all three of climate science impact and economics with a still stronger focus on lives and livelihoods including the risks of large scale migration and conflicts

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

electricity demand in tunisia this paper examines the global electricity demand in tunisia as a function of gross domestic product in constant price the degree of urbanization the average annual temperature and the real electricity price per kwh this demand will be examined employing annual data over a period spanning almost thirty one years from 1976 to 2006 a long run relationship between the variables under consideration is determined using the vector autoregressive regression the empirical results suggest that the electricity demand in tunisia is sensitive to its past value any changes in gross domestic product and electricity price the electricity price effects have a negative impact on long run electricity consumption however the gross domestic product and the past value of electricity consumption have a positive effect moreover the causality test reveals a unidirectional relationship between price and electricity consumption our empirical findings are effective to policy makers to maintain the electricity consumption in tunisia by using the appropriate strategy

residential demand for electricity abstract short and long run responses by households to changes in the price of electricity are estimated using data which permit measurement of the marginal price of electricity the infra marginal demand charge and estimates of household appliance stocks the price elasticities of high and low level users of electricity are compared the theoretical bias in price elasticity estimates resulting from neglect of the infra marginal demand charge is shown to be empirically insignificant

interfuel substitution results from several sectors of the greek economy abstract the purpose of this paper is to study interfuel substitution in various sectors of the greek economy an econometric model utilizing the translog cost function is estimated for three major sectors of the economy agriculture industry disaggregated also into three branches and transport fuels are aggregated into three categories solid fuels liquid fuels and electricity the model is estimated using time series data over the period 1960 1980 the results indicate substitutability between liquid fuels and electricity mainly complementarity between liquid and solid fuels and substitutability between electricity and solid fuels

a review of the stern review on the economics of climate change the stern review calls for immediate decisive action to stabilize greenhouse gases because the benefits of strong early action on climate change outweighs the costs the economic analysis supporting this conclusion consists mostly of two basic strands the first strand is a formal aggregative model that relies for its conclusions primari ly upon imposing a very low discount rate concerning this discount rate aspect i am skeptical of the review s formal analysis but this essay points out that we are actual ly a lot less sure about what interest rate should be used for discounting climate change than is commonly acknowledged the review s second basic strand is a more intuitive argument that it might be very important to avoid possibly large uncertain ties that are difficult to quantify concerning this uncertainty aspect i argue that it might be recast into sound analytical reasoning that might justify some of the review s conclusions the basic issue here is that spending money to slow global warming should perhaps not be conceptualized primarily as being about consump tion smoothing as much as being about how much insurance to buy to offset the small change of a ruinous catastrophe that is difficult to compensate by ordinary savings

repeated shocks and preferences for redistribution abstract a society that believes wealth to be determined by random luck rather than by merit demands more redistribution we present evidence of this behavior by exploiting a natural experiment provided by the l aquila earthquake in 2009 which hit a large area of central italy through a series of destructive shakes over eight days matching detailed information on the ground acceleration registered during each shock with survey data about individual opinions on redistribution we show that the average intensity of the shakes is associated with subsequent stronger beliefs that for a society to be fair income inequalities should be leveled by redistribution the shocks however are not all alike we find that only the last three shakes occurred on the fourth and the eighth day of the earthquake have a statistically significant impact overall we find that the timing and repetition of the shocks play a role in informing redistributive preferences

energy demand and environmental taxes the case of greece the purpose of this paper is to analyze the effects that energy taxes may have on reducing environmental pollution in greece we study the demand for residential energy for the period 1965 1998 and on the basis of these estimates we make forecasts for co2 emissions in the coming years furthermore we develop alternative scenarios for tax changes and study their effects on co2 emissions according to our findings the harmonization of the greek energy taxes to the average european union levels implies an increase of total co2 emissions by 6 annually if taxes are raised however to the highest european union levels the co2 emissions are restricted significantly these empirical findings may indicate that environmental taxation cannot be the unique instrument for combating pollution

electricity consumption in g7 countries a panel cointegration analysis of residential demand elasticities this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run and short run income and price elasticities for residential demand for electricity in g7 countries the panel results indicate that in the long run residential demand for electricity is price elastic and income inelastic the study concludes that from an environmental perspective there is potential to use pricing policies in the g7 countries to curtail residential electricity demand and thus curb carbon emissions in the long run

temperature and income reconciling new cross sectional and panel estimates this paper presents novel evidence and analysis of the relationship between temperature and income first using sub national data from 12 countries in the americas we provide new evidence that the negative cross country relationship between temperature and income also exists within countries and even within states second we provide a theoretical framework for reconciling the substantial negative association between temperature and income in the cross section with the even stronger short run effects of temperature estimated by panel models the theoretical framework suggests that half of the negative short term effects of temperature may be offset in the long run through adaptation this abstract was borrowed from another version of this item

coping with economic and environmental shocks institutions and outcomes moving to higher ground migration response to natural disasters in the early twentieth century areas differ in their propensity to experience natural disasters exposure to disaster risks can be reduced either through migration i e self protection or through public infrastructure investment e g building seawalls using migration data from the 1920s and 1930s this paper studies how the population responded to disaster shocks in an era of minimal public investment we find that on net young men move away from areas hit by tornados but are attracted to areas experiencing floods early efforts to protect against future flooding especially during the new deal era of the late 1930s may have counteracted an individual migration response

estimating deficit probabilities with price responsive demand in contract based electricity markets studies that estimate deficit probabilities in hydrothermal systems have generally ignored the response of demand to changing prices in the belief that such response is largely irrelevant we show that ignoring the response of demand to prices can lead to substantial over or under estimation of the probability of an energy deficit to make our point we present an estimation of deficit probabilities in chile s central interconnected system between 2006 and 2010 this period is characterized by tight supply fast consumption growth and rising electricity prices when the response of demand to rising prices is acknowledged forecasted deficit probabilities and marginal costs are shown to be substantially lower

poverty and witch killing many observers have noted that poverty and violence go hand in hand there is a strong negative relationship between economic growth and crime across countries as well as across districts in india and a link between low income and the occurrence of civil war 1 yet existing studies are typically unable to resolve the key econometric identification issues of omitted variable bias and endogeneity to illustrate the unobserved quality of local government institutions may affect both income growth and crime rates and poverty could lead to violence if desperate people with nothing to lose commit more crimes but violence itself may in turn affect economic productivity this paper uses local rainfall variation to identify the impact of income shocks on murder in a rural tanzanian district 2 extreme rainfall resulting in drought or floods is exogenous and is associated with poor harvests and near famine conditions in the region and a large increase in the murder of witches there are twice as many witch murders in years of extreme rainfall as in other years the victims are nearly all elderly women typically killed by relatives these econometric results across 11 years in 67 villages provide novel evidence on the role of income shocks in causing violent crime and religious violence in particular and also provide insights into witchcraft an important social phenomenon in africa rarely studied by economists the view that economic conditions are a driving force behind witch murders is bolstered by the fact that most witch killing in tanzania takes place in poor rural areas largely dependent on rain fed agriculture and that most victims in our sample are from poor households however it is difficult to definitively disentangle this income shock theory from alternative socio cultural explanations the concentration of tanzanian witch murders in a region dominated by one particular ethnic group the sukuma and the especially high number of witch murders in villages where indigenous religious beliefs are strong both point to the important role of non economic factors economic theories and cultural theories are perhaps best viewed as complements the empirical findings demonstrate the power of economics to rationalize a phenomenon that has previously been understood almost solely through a socio cultural lens 3

when the levee breaks black migration and economic development in the american south abstract in the american south postbellum economic development may have been restricted in part by white landowners access to low wage black labor this paper examines the impact of the great mississippi flood of 1927 on black out migration and subsequent agricultural development flooded counties experienced an immediate and persistent out migration of black population over time landowners in flooded counties modernized agricultural production and increased its capital intensity relative to landowners in nearby similar non flooded counties landowners resisted black out migration however benefiting from the status quo system of labor intensive agricultural production jel j15 j43 n32 n52 n92 q54 r23

estimation of urban residential electricity demand in china using household survey data abstract this paper uses annual urban household survey data of sichuan province from 2007 to 2009 to estimate the income and price elasticities of residential electricity demand along with the effects of lifestyle related variables the empirical results show that in the urban area of sichuan province the residential electricity demand is price and income inelastic with price and income elasticities ranging from 0 35 to 0 50 and from 0 14 to 0 33 respectively such lifestyle related variables as demographic variables dwelling size and holdings of home appliances are also important determinants of residential electricity demand especially the latter these results are robust to a variety of sensitivity tests the research findings imply that urban residential electricity demand continues to increase with the growth of income the empirical results have important policy implications for the multistep electricity price which been adopted in some cities and is expected to be promoted nationwide through the installation of energy efficient home appliances

using weather variability to estimate the response of savings to transitory income in thailand this paper measures the extent to which farmers are able to use savings and dissavings to smooth consumption in response to unexpected shocks to income time series information on regional rainfall is used to construct estimates of transitory income due to rainfall shocks the relationship between these measures of transitory income and savings indicates that farm households save a significantly higher fraction of transitory income than nontransitory income jel d91 016 the incomes of farm households in developing countries are notorious for being both low and uncertain policies that increase the incomes of farmers may well be different

can cultural norms reduce conflicts confucianism and peasant rebellions in qing china abstract can culture mitigate conflicts triggered by economic shocks in light of the extraordinary emphasis that confucianism places on subordination and pacifism we examine its role in possibly attenuating peasant rebellion within the historical context of china circa 1651 1910 our analysis finds that while crop failure triggers peasant rebellion its effect is significantly smaller in counties characterized by stronger confucian norms as proxied by confucian temples and chaste women this result remains robust after controlling for a long list of covariates and instrumenting confucian norms using ancient confucian sages 500 b c a d 550 to address concerns of measurement error and reverse causality

spatial and temporal efficiency in climate policy applications of fund fund is an integrated assessment model of the interactions between climate and economy nine world regions emit greenhouse gases and suffer damages from climate change a number of greenhouse gas emission reduction policies are compared including optimal and cost effective strategies strategies with early and late abatement and strategies with and without international co operation the analyses confirm that co operation matters resulting in substantially lower costs or higher welfare the real commitments of policy targets based on an absolute level e g 1990 emissions are hard to estimate because of the uncertainties in the baseline postponing action conflicts with minimising costs and maximising welfare but so does sharp emission reduction at the short term as proposed in the kyoto protocol

the economic effects of climate change greenhouse gas emissions are fundamental both to the world s energy system and to its food production the production of co2 the predominant gas implicated in climate change is intrinsic to fossil fuel combustion specifically thermal energy is generated by breaking the chemical bonds in the carbohydrates oil coal and natural gas and oxidizing the components to co2 and h2o one cannot have cheap energy without carbon dioxide emissions similarly methane ch4 emissions an important greenhouse gas in its own right are necessary to prevent the build up of hydrogen in anaerobic digestion and decomposition one cannot have beef mutton dairy or rice without methane emissions climate change is the mother of all externalities larger more complex and more uncertain than any other environmental problem the sources of greenhouse gas emissions are more diffuse than any other environmental problem every company every farm every household emits some greenhouse gases the effects are similarly pervasive weather affects agriculture energy use health and many aspects of nature which in turn affects everything and everyone the causes and consequences of climate change are very diverse and those in low income countries who contribute least to climate change are most vulnerable to its effects climate change is also a long term problem some greenhouse gases have an atmospheric life time measured in tens of thousands of years the quantities of emissions involved are enormous in 2000 carbon dioxide emissions alone and excluding land use change were 24 billion metric tons of carbon dioxide tco2

the electricity consumption and economic growth nexus evidence from greece abstract this paper attempts to cast light into the relationship between electricity consumption and economic growth in greece in a multivariate framework for this purpose we used cointegration techniques and the vector error correction model in order to capture short run and long run dynamics over the sample period 1970 2011 the empirical results reveal that in the long run electricity demand appears to be price inelastic and income elastic while in the short run the relevant elasticities are below unity we also argue that the causal relationship between electricity consumption and economic growth in greece is bi directional our results strengthen the notion that greece is an energy dependent country and well directed energy conservation policies could even boost economic growth furthermore the implementation of renewable energy sources should provide significant benefits ensuring sufficient security of supply in the greek energy system this evidence can provide a new basis for discussion on the appropriate design and implementation of environmental and energy policies for greece and other medium sized economies with similar characteristics

household demand for electricity the role of market distortions and prices in competition policy abstract this paper examines residential demand for electricity in sri lanka using survey data collected over a five year period between 2011 and 2015 the study finds that the major determinants of demand for residential electricity are the result of price or market distortions i e subsidies socioeconomic variables and energy saving technology the effects of these variables are particularly relevant to competition policy estimated elasticities with respect to average price subsidies under marginal cost pricing subsidies under average cost pricing and income are found to be 0 015 0 021 0 036 and 0 046 respectively we find that demand for electricity is inelastic and is categorised as a normal good however elasticities with respect to subsidy variables are found to be higher than the price variable this implies that under an increasing block rate system any price change used as a policy measure to control electricity consumption will not be effective this is because price changes could alter the subsidy received by the consumer and therefore reverse the objective of the price change further results of this study find that price and elasticities with respect to subsidy variables are relatively higher for low income groups while income elasticity is relatively larger for high income groups

optimal cities with indivisibility in production and interactions between firms abstract a fundamental question in urban economics is why cities exist we show that we can obtain agglomeration economies simply by combining the exchange of intermediate inputs with indivisibility in production in our model interactions between firms are market transactions and do not represent externalities in the usual sense combining them with indivisibility however creates locational externalities the optimal allocation requires pigouvian subsidies to firms and the externality version of the henry george theorem holds in our model we also obtain conditions for a monocentric configuration and perform comparative statics exercises

trends in rainfall and economic growth in africa a neglected cause of the african growth tragedy abstract we examine the role of rainfall trends in poor growth performance of sub saharan african nations relative to other developing countries using a new cross country panel climatic data set in an empirical economic growth framework our results show that rainfall has been a significant determinant of poor economic growth for african nations but not for other countries depending on the benchmark measure of potential rainfall we estimate that the direct impact under the scenario of no decline in rainfall would have resulted in a reduction of between around 15 and 40 of today s gap in african gdp per capita relative to the rest of the developing world

evolutionary modelling of the macro economic impacts of catastrophic flood events this paper examines the possible contribution of evolutionary economics to macro economic modelling of flood impacts to provide guidance for future economic risk modelling most macro economic models start from a neoclassical economic perspective and focus on equilibrium outcomes either in a static or dynamic way and describe economic processes at a high level of aggregation as a consequence they typically fail to account for the complexity of social interactions and other behavioural responses of consumers and producers to disasters which may affect the macroeconomic impacts of floods employing evolutionary principles and methods such as agent based modelling may help to address some of the shortcomings of current macro economic models we explore and discuss the implications of applying consumer and producer heterogeneity bounded rationality network effects social and technological learning co evolution and adaptive policy making concepts into existing economic frameworks for the assessment of macro economic impacts of floods authors abstract

residential demand for electricity the case of greece this paper examines the determinants of residential electricity consumption in greece over the period 1961 86 the paper presents first a brief description of the evolution of residential electricity consumption then it proceeds in the estimation of elasticities of residential demand for electricity using a single equation model with the ridge regression method the paper concludes that i the residential demand for electricity is price inelastic and income elastic ii there is high substitutability between electricity and lpg iii during the examined period the number of consumers played a very important role in the expansion of electricity consumption in greece and iv there is no regional variation in residential electricity demand

the growth aftermath of natural disasters this paper provides a description of the macroeconomic aftermath of natural disasters it traces the yearly response of gross domestic product growth both aggregated and disaggregated into its agricultural and non agricultural components to four types of natural disasters droughts floods earthquakes and storms the paper uses a methodological approach based on pooling the experiences of various countries over time it consists of vector auto regressions in the presence of endogenous variables and exogenous shocks varx applied to a panel of cross country and time series data the analysis finds heterogeneous effects on a variety of dimensions first the effects of natural disasters are stronger for better or worse on developing than on rich countries second while the impact of some natural disasters can be beneficial when they are of moderate intensity severe disasters never have positive effects third not all natural disasters are alike in terms of the growth response they induce and perhaps surprisingly some can entail benefits regarding economic growth thus droughts have a negative effect on both agricultural and non agricultural growth in contrast floods tend to have a positive effect on economic growth in both major sectors earthquakes have a negative effect on agricultural growth but a positive one on non agricultural growth storms tend to have a negative effect on gross domestic product growth but the effect is short lived and small future research should concentrate on exploring the mechanisms behind these heterogeneous impacts

short and long run elasticities of electricity demand in the korean service sector abstract this paper attempts to examine the electricity demand function in the korean service sector using the annual data covering the period 1970 2011 the short and long run elasticities of electricity demand with respect to price and income are empirically estimated using a co integration and error correction model the short and long run price elasticities are estimated to be 0 421 and 1 002 respectively the short and long run income elasticities are computed to be 0 855 and 1 090 respectively electricity demand in the service sector is inelastic to changes in both price and income in the short run but elastic in the long run therefore it appears that a pricing policy is more effective than the direct regulation of reducing electricity demand in the long run in order to stabilize the electricity demand in the service sector moreover it is necessary to encourage a more efficient use of electricity to cope with increasing demand for electricity following economic growth because the electricity demand in the service sector is income elastic in the long run

selling labor low wage responses to productivity shocks in developing countries productivity risk is pervasive in underdeveloped countries this paper highlights a way in which underdevelopment exacerbates productivity risk productivity shocks cause larger changes in the wage when workers are poorer less able to migrate and more credit constrained because of such workers inelastic labor supply this equilibrium wage effect hurts workers in contrast it acts as insurance for landowners agricultural wage data for 257 districts in india for 1956 87 are used to test the predictions with rainfall as an instrument for agricultural productivity in districts with fewer banks or higher migration costs the wage is much more responsive to fluctuations in productivity

energy demand in greece abstract this paper examines the impact of the two energy crises 1973 74 and 1978 79 on energy demand in greece initially some specific characteristics of energy consumption patterns before and after 1973 are presented and compared then demand parameters for hydroelectric energy liquid fuels and solid fuels were estimated using data for the period 1963 1984 and alternative econometric methods ols 2sls fiml to ensure that estimates do not vary across different estimation methods appropriate tests were used to examine whether a structural change in energy demand has occured following either of the two crises the results indicate that while consumption patterns may be different due to price and income changes after the crises the parameters of energy demand in greece have remained unchanged

here comes the rain again weather and the intertemporal substitution of leisure i revisit the intertemporal labor supply framework using exogenous variations in daily weather to see how time at work varies with rain in my model a rainy day is associated with a lower enjoyment of leisure effectively increasing wages and bringing more hours at work i test the model using data from the american time use survey supplemented with daily weather i find that on rainy days men shift on average 30 minutes from leisure to work computations give a rough estimate of the intertemporal elasticity of labor supply of around 0 01 in line with the rest of the literature

a regional dynamic general equilibrium model of alternative climate change strategies outcomes and noncooperative equilibria this study finds that cooperative policies show much higher levels of emissions reductions than do noncooperative strategies that there are substantial differences in the levels of controls in both the cooperative and the noncooperative policies among different countries and that high income countries may be the major losers from cooperation jel h41 q4 q2 q20

a review of the stern review on the economics of climate change how much and how fast should we react to the threat of global warming the stern review argues that the damages from climate change are large and that nations should undertake sharp and immediate reductions in greenhouse gas emissions an examination of the review s radical revision of the economics of climate change finds however that it depends decisively on the assumption of a near zero time discount rate combined with a specific utility function the review s unambiguous conclusions about the need for extreme immediate action will not survive the substitution of assumptions that are consistent with today s marketplace real interest rates and savings rates

networks in the modern economy mexican migrants in the u s labor market this paper attempts to identify job networks among mexican migrants in the u s labor market the empirical analysis uses data on migration patterns and labor market outcomes based on a sample of individuals belonging to multiple origin communities in mexico over a long period of time each community s network is measured by the proportion of the sampled individuals who are located at the destination the united states in any year we verify that the same individual is more likely to be employed and to hold a higher paying nonagricultural job when his network is exogenously larger by including individual fixed effects in the employment and occupation regressions and by using rainfall in the origin community as an instrument for the size of the network at the destination

estimating short and long term residential demand for electricity new evidence from sri lanka this study investigates the short run dynamics and long run equilibrium relationship between residential electricity demand and factors influencing demand per capita income price of electricity price of kerosene oil and price of liquefied petroleum gas using annual data for sri lanka for the period 1960 2007 the study uses unit root cointegration and error correction models the long run demand elasticities of income own price and price of kerosene oil substitute were estimated to be 0 78 0 62 and 0 14 respectively the short run elasticities for the same variables were estimated to be 032 0 16 and 0 10 respectively liquefied petroleum lp gas is a substitute for electricity only in the short run with an elasticity 0 09 the main findings of the paper support the following 1 increasing the price of electricity is not the most effective tool to reduce electricity consumption 2 existing subsidies on electricity consumption can be removed without reducing government revenue 3 the long run income elasticity of demand shows that any future increase in household incomes is likely to significantly increase the demand for electricity and 4 any power generation plans which consider only current per capita consumption and population growth should be revised taking into account the potential future income increases in order to avoid power shortages ill the country

poverty and crime in 19th century germany we estimate the impact of poverty on crime in 19th century bavaria germany rainfall is used as an instrumental variable for grain rye prices to address econometric identification problems in the existing literature the rye price was a major determinant of living standards during this period the rye price has a positive effect on property crime a one standard deviation increased property crime by 8 ols estimates are twice as large as instrumental variable estimates highlighting the value of our empirical approach higher rye prices lead to significantly less violent crime though and we argue that higher beer prices caused by the higher rye prices are a likely explanation

satellites self reports and submersion exposure to floods in bangladesh abstract a burgeoning climate economy literature has uncovered many effects of changes in temperature and precipitation on economic activity but has made considerably less progress in modeling the effects of other associated phenomena like natural disasters we develop new objective data on floods focusing on bangladesh we show that rainfall and self reported exposure are weak proxies for true flood exposure these data allow us to study adaptation giving accurate measures of both long term averages and short term variation in exposure this is important in studying climate change impacts as people will not only experience new exposures but also experience them differently
