the employment relationship in an almost structureless labour market the case of domestic work although domestic workers are generally engaged in informal contracts with hourly and daily wages some have formally written contracts and are paid monthly hourly and daily wages suggest flexible arrangements whereas the monthly payment system may be used to develop a stable relationship using original data from a sample of domestic workers in portugal we offer empirical evidence on predictors of four types of arrangement that combine formality and stability the results from multinomial logistic regression indicate that the wage level is a crucial predictor of the type of contract households seem to make a trade off between stable contracts and high level wages however the odds of being given a formal and stable contract increase when domestic workers have specific skills or are responsible for care and there are trust related issues our findings suggest that the use of flexible and informal labour has its limitations even in an activity perceived as non skilled

energy market liberalization and renewable energy policies in oecd countries abstract this paper investigates the effect of energy liberalization compared to other drivers on policies that support renewable energy in a long panel of oecd countries we estimate this effect by accounting for the endogeneity of liberalization related to joint decisions within a country s energy strategy using regulation in other industries as instruments we find that energy liberalization increases public support for renewable energy the effect of liberalization is the second largest after the effect of per capita income and is mostly driven by reductions in entry barriers while the effect of privatization is unclear this finding suggests that a reduction in the monopolistic power of state owned utilities has a positive effect on renewable energy policies when various types of actors are ensured access to the grid instead of it being provided to only a few large private firms

sheepskin effects in the returns to education some previous discussions have dismissed screening theories of education partly on the ground that diploma years of education do not confer especially large earnings gains similarly most empirical research on earnings functions has assumed an absence of sheepskin effects we report evidence however of substantial and statistically significant sheepskin effects although this suggests that the previous dismissals of the screening hypothesis were premature our evidence of sheepskin effects is amenable to nonscreening interpretations also according to screening theories of education individuals with more schooling tend to earn more not because or at least not solely because schooling makes them more productive but rather because it credentiates them as more productive a frequently cited article by layard and psacharopoulos 1974 however dismissed the importance of the screening hypothesis on the grounds that several of its refutable predictions were not supported by available evidence one of these was the sheepskin prediction that wages will rise faster with extra years of education when the extra year also conveys a certificate after surveying a number of studies layard and psacharopoulous henceforth lp concluded that rates of return to dropouts are as high as to those who complete a course which refutes the sheepskin version of the screening hypothesis since publication of the lp paper an undergraduate labor economics textbook has cited lp s analysis of sheepskin effects as telling criticism of the screening hypothesis a prominent proponent of the screening hypothesis riley 1979 has accepted lp s summary of the empirical evidence but responded that some versions of the screening hypothesis do not imply sheepskin effects in the meantime the ongoing flood of empirical research on earnings functions typically has continued to treat the natural logarithm of the wage rate as a linear or occasionally quadratic function of years of education with no allowance for discontinuities in diploma years 2 the estimated rates of return used by lp were based on data that did not disaggregate dropouts earnings by how many years of school they had completed lp acknowledged we would have preferred to show the earnings gain associated with each year of the course including the year when it was successfully completed this note presents a reanalysis of sheepskin effects based on the type of data lp wished they had the results contain very strong evidence of sheepskin effects after all the next section describes our analysis and the following section summarizes and discusses our

rates of time preference and consumer valuations of automobile safety and fuel efficiency this article estimates hedonic price models for automobiles using a data set on almost 3 000 households from the u s department of energy residential transportation energy consumption survey the standard hedonic models are generalized to recognize the role of discounting of fuel efficiency and safety yielding an estimated rate of time preference ranging from 11 to 17 percent this range includes the prevailing rate of interest for car loans in 1988 and is consequently consistent with market rates purchasers exhibit an implicit value of life ranging from 2 6 to 3 7 million which is within the range found in the labor market as well as other market contexts the model also estimates a significant price effect for auto injury risks and fuel efficiency

energy consumption and urban sprawl evidence for the spanish case residential electricity consumption constitutes one of the largest sources of spanish final energy demand to improve electricity savings policies oriented towards efficiency in residential consumption such as replacement of appliances or the construction of nearly zero energy buildings have been suggested and implemented however the potential relevance of urban structural characteristics such as the increase in detached houses in sprawling residential areas has not often been considered the aim of this research is to analyse the relevance of living in a detached house located in a dispersed urban area to household electricity consumption thus an electricity consumption model is estimated by using household socioeconomic variables and including urban characteristics as its determinants such us the level of urban agglomeration or whether families live in detached sprawling homes the model is estimated by using 2014 household budget survey hbs microdata and applying ordinary least squares ols as well as quantile regressions qr as econometric procedures endogeneity problems are corrected by means of instrumental variables the results confirm that living in a detached house significantly increases electricity consumption whereas urban agglomerations have the opposite effect sprawl is occurring rapidly in spanish cities and according to our results it could constitute a relevant source of increase in electricity demand in the following years

care regimes and national employment models rapid population ageing has dramatically increased the social and economic cost of elderly care demand for care labour is increasing rapidly and all countries are experiencing problems in recruiting enough workers to meet demand in some countries the shortage of care workers has been met by a large inflow of immigrant mostly female workers the paper s aim is twofold to argue that the way in which care is provided and financed may entail large differences in the creation of a formal care market provision in kind and tied monetary transfers that is cash benefits that are somehow regulated may prevent the formation of a large informal care market national employment models in turn shape the features of the care labour market in fact they affect the quantity and the quality of the care labour supply the size of the care labour shortage and the degree of dependence on migrant carers we show how these two factors combine to shape the characteristics of care regimes and their long term sustainability

the toxic intensity of industrial production global patterns trends and trade policy this paper exploits a newly developed data set to investigate recent changes in the international distribution of industrial pollution in particular the authors examine three issues 1 the relationship between the toxic intensity of industrial production and the level of economic development 2 the impact of oecd environmental regulation on global changes in toxic intensity and 3 the relationship between trade policy and the toxic intensity of industrial production in ldc s 10 refs

energy conservation investment do consumers discount the future correctly we argue that the apparently high discount rates attributed to investors making energy conservation investments are not irrational or the result of some market failure rather they may result from an investor recognizing that many conservation investments entail substantial sunk costs in the presence of these costs and uncertainty over future conservation savings consumers should use a higher hurdle rate for investment than if there were no uncertainty simulations suggest that the hurdle rate should be about four times greater than the standard rate an implication of our model is that tax subsidies for the purchase of conservation capital are likely to be ineffective we discuss alternative policy approaches which are more likely to increase energy efficient investment namely mandatory efficiency standards and energy taxes

economic growth pollution and renewable resources abstract this paper first analyzes a model of economic growth with stock pollution allowing smooth substitution between emissions and reproducible capital when emissions are optimally controlled the steady state consumption is lower than without pollution control but the optimal steady state equilibrium may not exist if the marginal productivity of capital is bounded the steady state is shown to be a local saddle point independent of the rate of discount if pollution is not controlled a competitive economy moves along a stable growth path toward a too heavily polluted steady state next a growth model in which pollution affects the growth of renewable resources is presented the conditions for the existence and saddle point property of the steady state are given and the consequences of nonoptimal externality taxes are discussed when renewable resources are included higher than optimal pollution may decrease steady state consumption contrary to the case where renewable resources are ignored

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

transboundary externalities in the environmental transition hypothesis the environmental kuznets curve ekc is a hypothesis which implies that it is possible to grow out of environmental degradation most theoretical models of the ekc relation have not accounted for transboundary and intergenerational externalities nor have empirical studies provided evidence that validates an inverted u shaped relation between environmental degradation and economic growth for pollution problems where the effects are far displaced or are long delayed

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

pay inequality and firm performance evidence from matched employer employee data a large matched employer employee data set for sweden is used to test several predictions from tournament theory for white collar workers a positive and significant effect of intra firm wage dispersion on profits and average pay is found using various measures of wage dispersion this result is robust for controlling for firm differences in human capital and firm fixed effects as well as for instrumenting the wage dispersion variable to take into account endogeneity of wage dispersion using data on around 10 000 managers a positive and significant association between pay dispersion and profits is also found for executives further results include a positive relationship between market demand volatility and wage dispersion measured as coefficient of variation in managerial pay and a negative effect of the number of managers contestants on managerial pay spread the first two results are in accordance with predictions from tournament theory while the last one is not

swedish co2 emissions 1900 2010 an exploratory note abstract this paper projects swedish co 2 emissions during the period 2000 2010 based on data covering 1900 1999 swedish climate policy is currently based on the assumption that carbon emissions will increase ceteris paribus by 5 15 relative to the 1990 level this forecast has motivated a number of policy measures including carbon taxes subsidies and an information package we find however that co 2 emissions may well be lower in the future this outcome is broadly consistent with the literature on the environmental kuznets curve which portrays the relationship between emissions and gdp the key contribution of this paper is that our analysis is based on a long time series current literature is invariably based on short panel data sets while we study a single country through several phases of development our analysis also sheds some light on the key importance played by nuclear power for carbon emission projections

rural residential energy transition and energy consumption intensity in china abstract this paper examines the impact of residential energy transition on residential energy consumption per capita recpc and identifies the underlying drivers in rural china based on province level panel data for years 1991 2014 in rural china it is shown that energy transition from traditional biomass energy tbe to traditional commercial energy tce significantly decreases recpc while energy transition from tbe or tce to advanced commercial energy ace significantly increases recpc as is revealed by the energy stacking model per capita income has a significantly negative impact on recpc and the impact of lagged recpc is opposite due to the regulation of energy price there exists price distortion in china s rural energy market and the price mechanism functions poorly besides factors including juvenile dependency ratio and education level significantly reduce recpc therefore it is vital to integrate rural energy into national energy strategic system facilitate energy transition process and introduce the market system reform of rural energy and continue to improve the education level of rural residents in rural china

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

evaluation of swedish youth labor market programs this paper evaluates two swedish active labour market programmes for youth namely youth practice and labour market training a non parametric matching approach is applied to estimate the average p

microdata evidence on rent sharing we examine the effect of firm profits on wages for individual workers while focusing on the empirical complications associated with estimating the extent of rent sharing controlling for worker and firm fixed effects and using several instruments to deal with the endogeneity of profits we report results indicating that ordinary least square ols estimates strongly underestimate the effects of profits on wages moreover the effect of profits on wages are estimated separately for firms with increasing and decreasing profits within a given time period we find a positive and stable effect only in firms with increasing profits this is in line with the idea that falling profits do not lead to wage cuts while increasing profits imply higher wages

are there limits to growth a simple theoretical model of pollution is developed that generates an inverted u shape relationship between per capita income and environmental quality this model is then used to study long run growth the same inverted u shape is shown to appear in time series and the prospects for sustained growth are shown to hinge on whether increasingly strict environmental regulation is compatible with a constant rate of return on capital implementation is also studied tax and voucher schemes are shown to have an advantage over direct regulation because they provide the correct incentives for capital accumulation copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the role of income in energy consumption behaviour evidence from french households data the main purpose of this paper is to characterise quantitatively the impact of income on household energy consumption in the residential and transport sectors starting from the data collected in a paper survey we analyse the extent of the constraint experienced by households in terms of equipment purchasing behaviour and daily energy consumption this analysis shows that the least well off households are particularly constrained since the share of their budget represented by these energy services is very large 15 25 and this corresponds to a level of energy service well below that of the better off households the case of space heating shows a factor of 2 in terms of level of comfort achieved between the extreme 10 percentiles these households also face a strong capital constraint for equipment purchases this leads either to a large increase in the required rate of return or to a reduction in the proportion of households that are prepared to replace their equipment earlier the least well off households are thus doubly constrained since it is more difficult for them to invest in our opinion it is crucial to take into account this observation in the context of political measures aimed at reducing households co2 emissions

unskilled urban migrant women and disguised employment home working women in istanbul turkey abstract formal and informal labor market opportunities for women are examined for turkey data collected from three surveys are used to describe types of home work and hourly wages are imputed for home work to compare with formal sector wages the number of migrant women who take home work in the city of istanbul is estimated

a bibliometric review energy consumption and greenhouse gas emissions in the residential sector residential sector has been one key sector for reducing its greenhouse gas emissions due to its significant contribution to global warming researchers in different countries have studied household energy consumption patterns and greenhouse gas emissions in order to promote low carbon lifestyles however few review papers have been published in this regard leading to a lack of systematic understanding on the related research achievements hence by using a bibliometric approach this paper aims to review the existing literature and examine the evolution of such a field so that the research trends can be uncovered including popular research methods citation analysis is performed to assess the influence of most productive journals countries territories and authors network analysis is also conducted to evaluate the relationship among different countries territories authors and keywords research outcomes of this paper present a comprehensive research picture on residential energy consumption and corresponding greenhouse gas emissions ree related papers published from 1997 to 2016 the most productive journals countries territories authors are also analyzed based on citation analysis and network analysis in addition results also revealed that behavioral analysis input output analysis life cycle assessment and cost benefit analysis are the most commonly used methods in this field results obtained from this study can provide valuable information for researchers interested in the ree related field

household energy choice and consumption intensity empirical evidence from bhutan abstract this paper uses data from three bhutan living standard surveys blss 2003 blss 2007 and blss 2012 to examine the trends and patterns of household energy consumption and identify and analyze the factors that influence household energy choices consumption intensity and the per capita household expenditure on energy sources in bhutan during the last decade significant numbers of bhutanese households have switched to cleaner energy sources empirical results show that a household s choice of cleaner energy sources is driven by income level and household wealth the age gender and education of the household heads access to electricity and location education and income have a differential role on the choice of clean or dirty fuel wealthier and more educated households use and rely more on clean sources of energy like electricity and liquid petroleum gas while poorer households use and rely on dirty fuel such as fuelwood and kerosene the study shows that female headed households are more likely to choose cleaner fuels and above all the availability of a clean and cost effective source of energy within proximity to the household is an important factor in the adoption of clean energy several models using a variety of alternative independent variables such as proxies for education and wealth were estimated and confirmed the robustness of the results

economic policy and special interest politics a great deal of research has been done on the boundary between economics and political science in the last five to ten years this research in political economics spans many subfields such as macroeconomics trade public finance regulation rational choice politics and game theory a common denominator has been to study structural models of the political process agents behave rationally within well specified economic and political institutions where the policymaking process is formulated as an extensive form game methodologically much progress has been made relative to traditional approaches which were often based on inconsistent or irrational political and economic behaviour relying on non derived influence functions political support functions or vote functions yet the modem work has largely developed separately in each subfield without much contact with other subfields and each of the resulting literatures tends to focus on a distinct but partial aspect of the political process in this lecture i shall argue that even though the progress to date has been substantial we can gain a better understanding of policymaking in democracies by combining the insights from different strands of thinking on some economic policy issues the conflicting views both among citizens and politicians basically reduce to a single left to right dimension examples may include the politics of inflation vs unemployment capital taxation or the size of government we can think about policy issues within this domain of general interest politics as being resolved via traditional downsian electoral competition at least to a first approximation but the economic policy process also allows narrow interest groups ample opportunities to concentrate benefits to their own group at the expense of the population as a whole the resulting policy conflict is generically multi dimensional resolving it by voting alone would thus result in condorcet cycles we therefore need to go beyond the simplest electoral models to understand policy determination within this domain of special interest politics this lecture deals with special interest politics to make my point about fruitful analytical arbitrage i will stick to the same underlying policy example throughout this will be a simple model of a society where the government uses

voting for environmental policy under income and preference heterogeneity we examine the design of policies for promoting the consumption of green products under preference and income heterogeneity using organic food products as an example two instruments are considered a price subsidy for the organic food products and a tax on the conventional products under income disparity consumers with high income always prefer a socially optimal subsidy to a socially optimal tax while low income consumers prefer a tax on conventional products when environmental policy is determined by the median voter the policies implemented tend to be stricter than socially optimal policies if income differences are large

economic growth inequality democratization and the environment we augment the stokey 1998 model by allowing agents to differ with respect to environ mental quality and income in order to analyze the impact of income and environmental inequality and of democratization on aggregate pollution we find that the impact of a more equal income distribution depends on the degree of democracy in a complete democracy a more equal income distribution generates ceteris paribus less pollution which is consistent with indirect empirical evidence whereas the opposite is the case if democratic rights are highly restricted furthermore a democratization is argued to typically lower both the income and the environmental quality of the median voter in this case if in utility terms the fall in environmental quality is worse than the fall in consumption the median voter decides to tighten environmental legislation so that aggregate pollution decreases

implications for the energy policy derived from the relation between the cultural dimensions of hofstede s model and the consumption of renewable energies abstract this paper aims to determine the relation between national culture and the consumption of renewable energies in several european countries according to the renewable energy directive of the european commission there have been set common goals for the share of consumption of renewable energies in the european union but each country is responsible for the action plan to achieve these targets these targets have been set based on the initial values of the renewable energies and on the natural resources of each country cultural aspects and energy consumption patterns have not been taken in consideration for the analysis of the willingness and motivation of consumers to switch towards renewable energies in this paper a panel data analysis has been carried out in order to measure the relation between hofstede s cultural dimensions and the share of renewable energies in final consumption the results show a highly significant relation between the masculinity index and the share of renewable energies and an acceptable relation for the long term orientation index the energy policy of the european union and of its countries should consider the cultural characteristics in the development of the national action plans for the implementation of renewable energies

implicit discount rates and the purchase of untried energy saving durable goods many consumers appear to rationally calculate the net worth of a household investment but a substantial minority may lack the skills or alertness to perceive an investment opportunity and initiate analysis intentions to engage in complementary activities play an important role in the investment decision

why did the west extend the franchise democracy inequality and growth in historical perspective during the nineteenth century most western societies extended voting rights a decision that led to unprecedented redistributive programs we argue that these political reforms can be viewed as strategic decisions by the political elite to prevent widespread social unrest and revolution political transition rather than redistribution under existing political institutions occurs because current transfers do not ensure future transfers while the extension of the franchise changes future political equilibria and acts as a commitment to redistribution our theory also offers a novel explanation for the kuznets curve in many western economies during this period with the fall in inequality following redistribution due to democratization i introduction the nineteenth century was a period of fundamental political reform and unprecedented changes in taxation and redistribution britain for example was transformed from an oligarchy run by an elite to a democracy the franchise was extended in 1832 and then again in 1867 and 1884 transferring voting rights to portions of the society with no previous political representation the decades after the political reforms witnessed radical social reforms increased taxation and the extension of education to the masses moreover as noted by kuznets inequality which was previously increasing started to decline during this period the gini coefficient for income inequality in england and wales had risen from 0 400 in 1823 to 0 627 in 1871 but fell to 0 443 in 1901 two key factors in the reduction in inequality were the increase in the proportion of skilled workers williamson 1985 and the redistribution of income toward the poorer segments of the society for example taxes rose from 8 12 percent of national product in 1867 to 18 8 percent by 1927 and the progressivity of the tax system increased substantially see lindert 1989

does skewed pattern of income distribution matter for the environmental quality evidence from selected brics economies with an application of quantile on quantile regression qqr approach abstract using annual data from 1980 to 2014 the study explores the relationship between carbon emissions and skewed pattern of income distribution among 4 selected brics economies e g brazil india china and south africa using quantile on quantile regression qqr technique of sim and zhou 2015 it tries to contribute towards an empirical understanding on the quantile structure of both the variables for the selected brics countries it finds for india and brazil that as income rises although both lower and upper income people degrade the environmental quality by releasing more co2 emissions but interestingly it is the poor who intensively degrade the environmental quality than the rich in sharp contrast for china and south africa it finds that it is the poor who relatively contribute less to the environmental degradation by reducing co2 emissions than the rich these findings have greater policy significances which are discussed at the concluding section in greater detail

household behavior and the use of natural gas for home heating the factors that determine energy use for home heating are investigated in this study household behavior and home characteristics prove to be the major determinants whereas attitudes are of minor importance home insulation has two opposing effects on energy use lower thermostat settings but more airing out of rooms

is there really a foreign ownership wage premium evidence from matched employer employee data numerous studies on firm level data have reported higher average wages in foreign owned firms than in domestically owned firms this however does not necessarily imply that the individual worker s wage increase with foreign ownership using detailed matched employer employee data on the entire swedish private sector we examine the effect of foreign ownership on individual wages controlling for individual and firm heterogeneity as well as for possible selection bias in foreign acquisitions we distinguish between foreign greenfields and takeovers and compare foreign owned firms with both domestic multinationals and local firms our results show a considerably smaller wage premium in foreign owned firms than what has been found in studies conducted at a more aggregate level moreover foreign takeovers of swedish firms tend to have no or even a negative effect on wages

inequality growth and environmental quality trade offs in a model with human capital accumulation this paper develops a simple endogenous growth model where pollution exposure and vulnerability are unequally spread across the population and growth and distribution are endogenous in this set up we investigate whether trade offs between growth distributional and environmental concerns may emerge we show that a tighter environmental policy reduces income inequality and can improve both growth and total welfare immediate welfare losses though do occur and are larger for countries that start at low levels of environmental quality e g developing countries inegalite croissance et qualite de l environnement arbitrages dans un modele d accumulation de capital humain nous developpons un modele de croissance endogene ou l exposition et la vulnerabilite a la pollution sont inegalement reparties dans la population et ou la croissance et la distribution des revenus sont determinees de facon endogene dans ce cadre d analyse nous cherchons s il existe des arbitrages entre la croissance les inegalites et l environnement notamment dans les pays en developpement nous montrons qu une politique environnementale plus stricte conduit a la fois a une reduction des inegalit es et a une augmentation de la croissance et du bien etre dans un premier temps cependant ce changement de politique conduit a une reduction du bien etre qui est relativement plus importante pour les pays dont la qualite environmentale est initiallement faible e g les pays en developpement

the prospects for caring economic theory and policy analysis this paper examines three distinguishing features of caring that it involves the development of a relationship that caring responsibilities and needs are unequally distributed and that social norms influence the allocation of care and caring responsibilities to draw out their implications for analysing caring and its movement between unpaid and paid economies rising opportunity costs of caring are found to produce pressures experienced in different ways across different sectors of the economy these coupled with inequalities in care responsibilities and labour market opportunities influence the movement of care between paid and unpaid economies this analysis is then used to examine the likely evolution of caring norms and practices and how policy might intervene to avoid an uncaring future

an overlapping generations model of growth and the environment this article analyzes the potential conflict between economic growth and the maintenance of environmental quality in an overlapping generations model short lived individuals make decisions which have long lasting effects on both factor productivity and the environment the model provides a theoretical explanation of observed correlations between environmental quality and income whereby economic growth is associated first with declines then improvements in environmental quality it suggests circumstances in which multiple pareto ranked steady state equilibria may arise and in which sustained growth of both capital and environmental quality may occur overmaintenance of the environment analogous to dynamically inefficient overaccumulation of capital may emerge copyright 1994 by royal economic society

the acid rain game as a resource allocation process with an application to the international cooperation among finland russia and estonia we consider optimal cooperation in transboundary air pollution abatement among several countries under incomplete information i e local information only on marginal emission abatement costs and damage costs directions of emission abatement in each country are determined that generate a succession of emissions programs shown to converge to an economic optimum a cost sharing scheme that results from appropriately designed international transfers guarantees that the individual costs of all parties are nonincreasing along the path towards the optimum a version of maler s 1989 acid rain game is used for a numerical application

excessive environmental risks an intergenerational market failure abstract this paper cautions against the belief that markets work efficiently in transmitting across generations the right signals for investment decisions under risk overlapping generation models are used to show that the incompleteness of intergenerational insurance markets constitutes a market failure that leads to inefficient intergenerational investment decisions under risk early generations over diversify if they face risks that are larger than those of the following generation and could therefore be shared with them on the other hand if risks are increasing from generation to generation the current generation would under insure against those risks since the direction of the inefficiency depends on the nature of the risk assumed the policy implications depend on the empirical assessment of the risks that current and future generations are facing this paper provides applications of the general result to environmental problems such as inefficiently low protection against global warming the excessive reduction of biodiversity and inefficient depletion of a natural resource

the rebound effect for space heating empirical evidence from austria abstract the major focus of this paper is to investigate the magnitude of the rebound effect for space heating in austria different approaches are applied and compared the most important result of this investigation is that despite the fact that all approaches applied have their weaknesses and some results were not highly significant the final outcomes of the different approaches show quite good coincidence they provide evidence of a rebound effect between 20 and 30 the most important conclusions for energy policy makers are i standards with respect to building codes are very important tools to increase the thermal quality of new buildings ii due to prevailing low energy prices a triggering tool which may be rebates or loans has to be implemented to increase the efficiency of the building stock
