barriers to energy efficiency a comparison across the german commercial and services sector abstract based on a large sample for the german commercial and services sector this paper econometrically assesses the relevance of various types of barriers to energy efficiency at the sectoral level and across fifteen sub sectors the results at the level of entire sectors suggest that the lack of information about energy consumption patterns and about energy efficiency measures lack of staff time priority setting within organizations and in particular the investor user dilemma are all relevant barriers allowing for sector specific differences in the relevance of these individual barriers yields a more heterogeneous picture the numbers and types of relevant barriers vary across sub sectors and the majority of sub sectors are subject to relatively few barriers the statistically most significant barriers are found for the sub sector of public administrations these findings are robust independent of whether the definition of an organization s energy efficiency performance includes only measures that have actually been realized or also those that are being planned for planned projects however organizations appear to underestimate internal priority setting as a barrier to energy efficiency

the structure of energy efficiency investment in the uk households and its average monetary and environmental savings abstract socioeconomic and behavioural variables that influence the household s adoption of energy efficiency measures such as cavity and loft insulation and upgrades to the boiler are identified contrary to previous literature by extending brechling and smith s 1994 and hassett and metcalf s 1995 models it is shown that the application of the energy act 2011 which contains provisions on the green deal the new energy company obligation eco and the private rented sector needs to follow a tailored strategy to reach the low adoption households identified by my model moreover for the current adopters of the analysed measures average monetary and environmental adoption benefits are estimated based on parti and parti s 1980 demand model these estimates are smaller than their expected values showing an important energy efficiency gap in the sector particularly low cost measures can bring important savings that can help to meet the pay as you save rule i e the golden rule of the new regulation my model also shows that a poor state of dwelling repair can reduce the adoption benefits increasing the need of subsidies that will be financed through consumer s energy bills however this can increase the number of households in fuel poverty

income redistribution in a common labor market when households are mobile among jurisdictions income redistribution by individual jurisdictions creates fiscal externalities a model of interjurisdictional migration is used to study the nature of this redistributive externality analysis of optimal redistribution and optimal corrective subsidies from higher level governments shows that benefit levels for the recipients of income transfers and tax rates on mobile taxpayers should be equalized across jurisdictions a system of jurisdictions with a common labor market can achieve welfare improvements through coordination of domestic redistributive policy or through the intervention of a higher level government copyright 1991 by american economic association

infrastructure quality and the subsidy trap abstract electricity and water are often subsidized in developing countries to increase their affordability for low income households ideally such subsidies would create sufficient demand in poor neighborhoods to encourage private investment in their infrastructure instead many regions receiving large subsidies have precarious distribution networks supplying users who never pay using a structural model of household electricity demand in colombia i predict the change in consumption and profits from upgrading low quality electricity connections i show that the existing subsidies which provide greater transfers to areas with unreliable supply deter investment to modernize infrastructure finally i analyze alternative programs with stronger investment incentives jel h23 h54 l94 l98 o12 o13

are chinese cities too small this paper models and estimates net urban agglomeration economies for cities economic models of cities postulate an inverted u shape of real income per worker against city employment where the inverted u shifts with industrial composition across the urban hierarchy of cities this relationship has never been estimated in part because of data requirements china has the necessary data and context we find that urban agglomeration benefits are high real incomes per worker rise sharply with increases in city size from a low level they level out nearer the peak and then decline very slowly past the peak we find that a large fraction of cities in china are undersized due to nationally imposed strong migration restrictions resulting in large income losses

is there an energy efficiency gap many analysts have argued that energy efficiency investments offer an enormous win win opportunity to both reduce negative externalities and save money this overview paper presents a simple model of investment in energy using capital stock with two types of market failures first uninternalized externalities from energy consumption and second forces such as imperfect information that cause consumers and firms not to exploit privately profitable energy efficiency investments the model clarifies that only if the second type of market failure cannot be addressed directly through mechanisms such as information provision energy efficiency subsidies and standards may be merited this chapter therefore reviews the empirical work on the magnitude of profitable unexploited energy efficiency investments a literature which frequently does not meet modern standards for credibly estimating the net present value of energy cost savings and often leaves other benefits and costs unmeasured these problems notwithstanding recent empirical work in a variety of contexts implies that on average the magnitude of profitable unexploited investment opportunities is much smaller than engineering accounting studies suggest finally there is tremendous opportunity and need for policy relevant research that utilizes randomized controlled trials and quasi experimental techniques to estimate the returns to energy efficiency investments and the welfare effects of energy efficiency programs

an empirical analysis of intergovernmental tax interaction the case of business income taxes in canada both federal and provincial governments in canada levy corporate taxes on busi nesses in their jurisdictions which potentially gives rise to horizontal and vertical tax exter nalities within the federation using a simple model of interdependent tax choices we estimate tax setting functions for the federal government ontario quebec and an aggregate of the remaining eight provinces we find evidence of significant vertical and horizontal tax inter actions provincial tax rates respond negatively to the federal tax rate while at least some provinces increase their tax rates in response to increases in the tax rates of other provinces

economic growth in a cross section of cities abstract we examine the relationship between urban characteristics in 1960 and urban growth between 1960 and 1990 income and population growth move together and both types of growth are 1 positively related to initial schooling 2 negatively related to initial unemployment and 3 negatively related to the initial share of employment in manufacturing racial composition and segregation are uncorrelated with urban growth across all cities but in cities with large nonwhite communities segregation is positively correlated with population growth government expenditures except for sanitation are uncorrelated with growth government debt is positively correlated with later growth

normal markets market imperfections and energy efficiency abstract the conventional distinction between economic and engineering approaches to energy analysis obscures key methodological issues concerning the measurement of the costs and benefits of policies to promote the adoption of energy efficient technologies the engineering approach is in fact based upon firm economic foundations the principle of lifecycle cost minimization that arises directly from the theory of rational investment thus evidence that so called market barriers impede the adoption of cost effective energy efficient technologies implies the existence of market failures as defined in the context of microeconomic theory problems of imperfect information and bounded rationality on the part of consumers for example may lead real world outcomes to deviate from the dictates of efficient resource allocation a widely held contrary view that the engineering view lacks economic justification is based on the fallacy that markets are normally efficient

difficulty is critical the importance of social factors in modeling diffusion of green products and practices abstract despite the very positive as measured by market surveys attitude towards eco innovations and sustainability in general the actual market penetration of green products and practices generally falls behind the expectations in this paper we argue that considering difficulty of engagement as used in the campbell paradigm is of critical importance when modeling diffusion of eco innovations such a notion of difficulty possesses three desired properties i parsimony it is represented by a single value ii interpretability it can be regarded as an estimator of the otherwise complex notion of behavioral cost and iii applicability it can be easily measured through market surveys in an extensive simulation and analytical study involving empirically measured difficulty and an agent based model spanned on different social network structures we show that innovation adoption may exhibit abrupt changes in market penetration as a result of even small changes in difficulty the latter may be of particular interest to policy makers who have to make strategic decisions when introducing socially but not necessarily individually desired products and practices like dynamic or green electricity tariffs

a new product growth for model consumer durables this article originally appeared in management science january 1969 volume 15 number 5 pp 215 227 published by the institute of management sciences a growth model for the timing of initial purchase of new products is developed and tested empirically against data for eleven consumer durables the basic assumption of the model is that the timing of a consumer s initial purchase is related to the number of previous buyers a behavioral rationale for the model is offered in terms of innovative and imitative behavior the model yields good predictions of the sales peak and the timing of the peak when applied to historical data a long range forecast is developed for the sales of color television sets

investment inefficiency and the adoption of eco innovations the case of household energy efficiency technologies abstract this paper examines the factors determining household adoption of energy efficiency eco innovations we do so by testing hypotheses grounded in diffusion and finance theory and the literature on the barriers to energy efficiency using two large surveys of uk households we explore the adoption of nine technologies our results indicate investment inefficiency amongst household adopters occurs for two reasons first contrary to notions of rational choice we find a negative relationship between the investment return of technologies and their level of diffusion second we show adopters of these technologies display characteristics broadly consistent with diffusion theory contradicting the prediction of finance theory that investment return not individual characteristics should drive adoption we also find that policy has played a role in inducing the diffusion of these technologies and that tenure and spill over effects are important in adoption finally adoption is motivated more by a desire to save money than by environmental concern we conclude by giving examples of how our research can lead to better policy timing and targeting

evidence on the political economy of the urbanization process urbanization and economic development go hand in hand as a country moves from a rural agricultural base to an urban industrial base this paper argues that urbanization per se occurs in response to the basic sector shift out of agriculture and government policies such as price controls and trade protection of industry affect the process only indirectly through their effect on sector composition however urban concentration the extent to which a country s urban resources are concentrated in one or two large cities as opposed to more evenly spread is much more directly affected by policies and politics the paper finds specifically that investments in inter regional infrastructure facilitates urban deconcentration away from primate to hinterland cities as does increasing democratization or increasing fiscal decentralization the findings move beyond establishing basic correlations in the data to trying to quantify causal effects in a panel framework with instrumental variables estimation

a theory of urban growth in an economy experiencing endogenous economic growth and exogenous population growth we explore two main themes how urbanization affects efficiency of the growth process and how growth affects patterns of urbanization localized information spillovers promote agglomeration and human capital accumulation fosters endogenous growth individual city sizes grow with local human capital accumulation and knowledge spillovers and city numbers generally increase which we demonstrate is consistent with empirical evidence we analyze whether local governments can successfully internalize local dynamic externalities in addition we explore how growth involves real income differences across city types and how urbanization can foster income inequality most nonagricultural production in developed countries occurs in metropolitan areas the underlying reasons why economic activity agglomerates into cities localized information and knowledge spillover also make cities the engines of economic growth in an we gratefully acknowledge support of the national science foundation grants sbr 9422440 and sbr9730142 for this research the work has benefited from conversations with harl ryder on the dynamics of the model and from comments by gilles duranton and participants in seminars at brown colorado and texas austin and a presentation at an isit seminar sponsored by the centre for economic policy research and the national bureau of economic research

industrial centralization in indonesia in certain situations economic liberalization policies can increase the degree of spatial centralization of resources and spatial concentration of manufacturing in large metropolitan areas in addition historical patterns of location make it difficult to alter the degree of centralization this article explores these issues by specifying and estimating a nested logit model of industrial location of manufacturing activity in java focusing on the unincorporated sector the results indicate that plants strongly prefer locations with mature plants in related industries which offer a built up stock of local knowledge in addition the 1983 liberalization in indonesia was associated with increased centralization of the unincorporated sector although the liberalization gave unincorporated firms better access to government and other centralized services firms needed to centralize to take advantage of these opportunities because the bureaucratic process is centralized and communications are poor the relative increased growth of the corporate sector following liberalization may also have helped to further draw unincorporated plants into centralized locations

budget spillovers and fiscal policy interdependence evidence from the states abstract this paper formalizes and tests the notion that states expenditures depend on the spending of similarly situated states we find that even after allowing for fixed state effects year effects and common random shocks among neighbors a state government s level of per capita expenditure is positively and significantly affected by the expenditure levels of its neighbors ceteris paribus a one dollar increase in a state s neighbors expenditures increases its own expenditure by over 70 cents

unexpected guests the impact of internal displacement inflows on rental prices in colombian host cities abstract we study the causal impact of internally displaced people idp inflows on rental prices in colombian host cities following an instrumental variables approach we find that as idp inflows increase low income rental prices increase and high income rental prices decrease we provide empirical evidence on two potential mechanisms for these findings excess demand for low income housing puts upwards pressure on rental prices increasing supply of high income housing coupled with rising homicide rates put downwards pressure on rental prices

infrastructure provision gender and poverty in indian slums we examine the relationship between infrastructure provision and poverty alleviation by analyzing 500 interviews conducted in serviced and non serviced slums in india using a mixed method approach of qualitative analysis and regression modeling we find that infrastructure was associated with a 66 increase in education among females service provision increased literacy by 62 enhanced income by 36 and reduced health costs by 26 evidence suggests that a gender sensitive consideration of infrastructure is necessary and that a one size fits all approach will not suffice we provide evidence that infrastructure investment is critical for well being of slum dwellers and women in particular

investment in energy efficiency do the characteristics of firms matter the literature on energy efficiency provides numerous examples of apparently profitable technologies that are not universally adopted yet according to the standard neoclassical theory of investment profit maximizing firms should undertake all investments with a positive net present value the standard theory also holds that the discount rate for computing the present value of a project should be the return available on other projects in the same risk class and therefore should not depend on characteristics of the firm this model as applied to energy saving investments is tested by examining whether firms characteristics influence their decision to join the environmental protection agency s voluntary green lights program a discrete choice regression is estimated over a large sample of participating and nonparticipating firms missing values in the data matrix are replaced with multiple imputations from a distribution estimated using the expectation maximization algorithm the results show that 1 sub

technological diffusion and preference learning in the world of homo sustinens the challenges for politics abstract this article relates agents learning of a preference for a technology competition of technologies and their relative diffusion among potential adopters competitive interactions between two technologies are captured by an extended lotka volterra model to also incorporate preference learning on the part of potential adopters of these technologies we combine it with a model of cultural learning based on role model conformist and hedonistic learning our theoretical analysis is illustrated by a concrete example the competition between electric mobility and conventional forms of individual mobility the model enables an evaluation of specific policy instruments as to the promotion of sustainable technology

sewers diffusion and the decline of mortality the case of paris 1880 1914 it is common to argue that water infrastructure innovations improve life expectancy yet the benefits of clean water depend on a mechanism to dispose of waste water we draw on the historical experience of a large industrial city to estimate the impact of the spread of the sewer system using a longitudinal data set on mortality and rents for each of paris 80 neighborhoods we show that sanitation contributed several years to life expectancy these results point out the multiplicity of infrastructure needed to help decrease mortality

consumer responses towards home energy financial incentives a survey based study abstract residential energy efficient and renewable energy eere products play an important role in energy conservation and carbon emissions reduction various financial incentive programs have been developed to promote the adoption of these products however their effectiveness in attracting consumers is not very well understood in this study we investigated impacts of financial incentives on homeowner s decision making towards six eere products two forms of incentives tax credits and interest free loans were examined through a household mailing survey in florida the united states results showed that although half of the respondents were interested in eere products the high investment cost was a major concern that hindered their purchase activities homeowners were attracted to financial incentives and valued tax credits much higher than interest free loans the current federal home energy tax credit levels were found to attract only 2 12 percent of homeowners to buy eere products the willingness of participation was especially low for the costly products such as solar panels the participation rate was also very low for lower income i e annual household income below 50 000 families living in older residences this study contributes to the understanding of economic and social aspects of consumer decision making on energy efficiency and alternative energy

the value of social networks in the diffusion of energy efficiency innovations in uk households abstract the uk government has policy goals for increasing energy efficiency in existing homes however there are doubts that standard technology and behavioural innovations will be adopted widely enough in time to achieve the targets diffusion of innovation theory states that the communication of information on innovations through a social system encourages adoption social capital theory states that interpersonal communication is a key means of gaining resources such as information on energy efficiency innovations for attaining certain goals case study research of three british communities was conducted in 2009 in order to understand the influence of social capital on information diffusion regarding the adoption of household energy efficiency measures the findings show that while standard campaigns may account for two thirds of information seeking behaviour they may not be addressing up to one third of information seekers who would prefer to speak to people they know findings also indicate that seeking information amongst personal contacts is often associated with adoption of energy efficiency innovations increasing the likelihood of adoption by up to four times but that there are important differences between types of innovations and communities tailoring campaigns to communities communication channels is therefore imperative these findings have important implications for informing community based energy efficiency programmes

zipf s law for cities an explanation zipf s law is a very tight constraint on the class of admissible models of local growth it says that for most countries the size distribution of cities strikingly fits a power law the number of cities with populations greater than s is proportional to 1 s suppose that at least in the upper tail all cities follow some proportional growth process this appears to be verified empirically this automatically leads their distribution to converge to zipf s law

the attenuation of human capital spillovers abstract this paper uses 2000 census data to estimate the relationship of agglomeration and proximity to human capital to wages the paper takes a geographic approach and focuses on the attenuation of agglomeration and human capital effects differencing and instrumental variable methods are employed to address endogeneity in the wage agglomeration relationship and also to deal with measurement error in our agglomeration and human capital variables three key results are obtained first the spatial concentration of employment within five miles is positively related to wage second the benefits of spatial concentration are driven by proximity to college educated workers an instance of human capital spillovers third these effects attenuate sharply with distance

decentralization and pollution spillovers evidence from the re drawing of county borders in brazil decentralization can improve service delivery but it can also generate externalities across jurisdictional boundaries we examine the nature and size of water pollution externalities as rivers flow across jurisdictions panel data on water pollution in brazilian rivers coupled with county splits that change the locations of borders allow us to identify the spatial patterns of pollution as rivers approach and cross borders controlling for fixed effects and trends specific to each location the theory of externalities predicts that pollution should increase at an increasing rate as the river approaches the downstream exit border that there should be a structural break in the slope of the pollution function at the border and that a larger number of managing jurisdictions should exacerbate pollution externalities we find support for all four predictions in the data satellite data on growth in night time lights along rivers show that local authorities allow more settlements to develop close to rivers in the downstream portions of counties which is the likely underlying mechanism the border effects on pollution are not as pronounced when the cost of inter jurisdictional coordination is lower

a review of the age of sustainable development by jeffrey sachs how does economic science inform the study of sustainable development in his new book jeffrey d sachs analyzes the challenges of achieving economic growth while protecting the environment and achieving an equitable distribution of resources this review presents an overview of this ambitious book with special emphasis on the role of the objectives of local and national leaders and their incentives to pursue the sustainability agenda given the huge migration to cities now playing out in the developing world special attention is paid to the role of urbanization as a cause of sustainability opportunities and challenges

environmental externalities and immiserizing structural changes in an economy with heterogeneous agents the way in which natural and physical capital are accumulated distributed and harnessed underpins the functioning and sustainability of the productive system of each society as well as its social stratification significant changes in the interactions between natural and physical capital accumulation give rise to processes of structural change sc which affect not only sectoral composition of the productive system but also social equity and environmental quality we propose a taxonomy of different scs on the basis of distributive environmental and economic outcomes and we study a two sector model with environmental externalities to identify under which conditions each sc can occur our model shows how the type of sc is shaped by the link between agents heterogeneity in terms of productive asset endowment and their vulnerability to environmental degradation in particular we find that a sc associated with reduction in poverty and in environmental pressures can occur only if productivity of the physical capital intensive sector increases but its rate of environmental impact remains relatively lower than that of the natural capital intensive sector

how high are option values in energy efficiency investments high implicit discount rates in consumers energy efficiency investments have long been a source of controversy in several recent papers hassett and metcalf argue that the uncertainty and irreversibility attendant to such investments and the resulting option value account for this anomalously high implicit discounting using their model and data we show that to the contrary their analysis falls well short of providing an explanation of this pattern

what is different about urbanization in rich and poor countries cities in brazil china india and the united states abstract are the well known facts about urbanization in the united states also true for the developing world we compare american metropolitan areas with analogous geographic units in brazil china and india both gibrat s law and zipf s law seem to hold as well in brazil as in the u s but china and india look quite different in brazil and china the implications of the spatial equilibrium hypothesis the central organizing idea of urban economics are not rejected the india data however repeatedly rejects tests inspired by the spatial equilibrium assumption one hypothesis is that spatial equilibrium only emerges with economic development as markets replace social relationships and as human capital spreads more widely in all four countries there is strong evidence of agglomeration economies and human capital externalities the correlation between density and earnings is stronger in both china and india than in the u s strongest in china in india the gap between urban and rural wages is huge but the correlation between city size and earnings is more modest the cross sectional relationship between area level skills and both earnings and area level growth are also stronger in the developing world than in the u s the forces that drive urban success seem similar in the rich and poor world even if limited migration and difficult housing markets make it harder for a spatial equilibrium to develop

incumbent behavior vote seeking tax setting and yardstick competition this paper develops a model of the political economy of tax setting in a multijurisdictional world where voters choices and incumbent behavior are determined simultaneously voters are assumed to make comparisons between jurisdictions to overcome political agency problems this forces incumbents into a yardstick competition in which they care about what other incumbents are doing we provide a theoretical framework and empirical evidence using u s state data from 1960 to 1988 the results are encouraging to the view that vote seeking and tax setting are tied together through the nexus of yardstick competition

residential energy efficient technology adoption energy conservation knowledge and attitudes an analysis of european countries abstract relationships between measures of household energy use behavior and household characteristics are estimated using a unique dataset of approximately 5000 households in 10 eu countries and norway family age composition patterns are found to have a distinct impact on household energy use behavior households with young children are more likely to adopt energy efficient technologies and energy conservation practices and place primary importance on energy savings for environmental reasons by contrast households with a high share of elderly members place more importance on financial savings and have lower levels of technology adoption energy conservation practice use and knowledge about household energy use education levels also matter with higher levels associated with energy efficient technology adoption and energy conservation practice use similarly university education increases the stated importance of energy savings for greenhouse gas reductions and decreases the stated importance for financial reasons education impacts also vary greatly across survey countries and there is some evidence of an eastern western european divide with respect to attitudes towards energy savings these cross country differences highlight the need to balance a common eu energy efficiency policy framework with flexibility for country specific policies to address unique constraints to energy efficient technology and conservation practice adoption

exclusionary policies in urban development under servicing migrant households in brazilian cities localities in developed countries often enact regulations to deter low income households from moving in in developing countries such restrictions lead to the emergence of informal housing sectors to deter low income migrants localities in developing countries withhold public services to the informal housing sector using a large sample of brazilian localities we examine migration and exclusion focusing on the public provision of water to small houses where low income migrants are likely to live withholding water connections reduces the locality growth rate particularly of low education households in terms of service provision during dictatorship in brazil we find evidence of strategic exclusion where localities appear to withhold services to deter in migration we also find evidence of strategic interactions among localities within metro areas in their setting of service levels if one locality provides more services to migrant households other localities respond by withholding service

welfare reform and the race to the bottom theory and evidence economists have argued that welfare migration leads to a race to the bottom in the choice of welfare benefits although a system of federal matching grants can remedy this problem the recent welfare reform law replaced the existing matching grant structure with block grants a policy change that appears undesirable to judge whether this critique of welfare reform is justified this paper evaluates the evidence in favor of a race to the bottom after explaining the theoretical effects of welfare migration the paper surveys the empirical evidence on the occurrence of such migration concluding that the evidence is mixed the discussion also considers recent empirical tests for strategic interaction which show that benefit levels in nearby states affect a given state s benefit choice the most plausible source of such interaction is a concern about welfare migration which leads policymakers to look at benefits in neighboring states when making their own choices judging that the evidence appears consistent with the existence of a race to the bottom the paper concludes that the demise of matching grants may be undesirable from a policy perspective
