the demand for housing in sweden equilibrium choice of tenure and type of dwelling abstract most studies of housing demand and tenure choice only identify two modes of tenure owner occupied one family houses and rental apartments furthermore they are typically based on a cross section across all households in this study we use recent swedish data to overcome these weaknesses we identify owner occupied apartments coop shares as a third mode of tenure and show that this should be treated separately we also use information about the household s own assessment of its probability of moving during the next year we demonstrate that it makes a large difference if likely movers are eliminated from the sample

the importance of comprehensiveness in renewable electricity and energy efficiency policy based on extensive research interviews and supplemented with a review of the academic literature this article assesses the best way to promote renewable energy and energy efficiency it begins by briefly laying out why government intervention is needed and then details the four most favored policy mechanisms identified by participants eliminating subsidies for conventional and mature electricity technologies pricing electricity accurately passing a national feed in tariff and implementing a nationwide systems benefit fund to raise public awareness protect lower income households and administer demand side management programs drawing mostly from case studies in the united states the article also discusses why these policy mechanisms must be implemented comprehensively not individually if the barriers to renewables and energy efficiency are to be overcome

european schemes for promoting renewables in liberalised markets abstract the paper describes possibilities and problems for penetration of supply systems based on renewable energy sources in liberalised markets the analysis is based on recent development in eu with different models for support of installations based on renewable energy these include feed in models with guaranteed minimum tariffs tender models for different bands of technologies and green certificates trading models with obligatory consumer quota the paper describes the market situation in selected european countries including germany the uk holland and denmark an eu directive from september 2001 has postponed the decision on a possible harmonisation of promotional models until at least 2005 in order to obtain more practical experience with the different support schemes a critical evaluation is given in this paper of the different models with proposals for a balanced development between environmental and trading concerns it is argued that too much emphasis is presently given to the side of free trade at the expense of long range planning for a sustainable energy development

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

a microsimulation model of swedish housing demand abstract this paper presents a microsimulation model of housing demand aimed at analyzing effects of changes in tax schedules like many other countries sweden s income tax laws treat homeowners and renters asymmetrically therefore most changes in tax laws will affect housing demand and tenure choice we develop a microsimulation model which generates consistent estimates of the mean and variance of total housing demand and show that commonly used measures like analytic elasticities evaluated at mean values of the exogenous variables can yield very misleading predictions our model can be used to simulate almost any change in the tax system here we report results of three simple experiments one of which is a change in the rate at which imputed income from owner occupied housing is taxed

distributional impacts of state level energy efficiency policies in regional electricity markets abstract a number of u s states have passed legislation targeting energy efficiency and peak demand reduction we study one such state pennsylvania within the context of pjm a regional electricity market covering numerous different states our focus is on the distributive impacts of this policy specifically how the policy is likely to impact electricity prices in different areas of pennsylvania and in the pjm market more generally such spatial differences in policy impacts are difficult to model and the transmission system is often ignored in policy studies our model estimates supply curves on a zonal basis within regional electricity markets and yields information on price and fuel utilization within each zone we use the zonal supply curves estimated by our model to study regional impacts of energy efficiency legislation on utilities both inside and outside of pennsylvania for most utilities in pennsylvania it would reduce the influence of natural gas on electricity price formation and increase the influence of coal it would also save 2 1 to 2 8 percent of total energy cost in pennsylvania in a year similar to 2009 the savings are lower than 0 5 percent in other pjm states and the prices may slightly increase in washington dc area

energy comes home the growth in private energy consumption is an increasing problem in western countries from an environmental point of view this consumption has to be reduced on the basis of two norwegian case studies this article discusses private energy consumption and possibilities for reduction with a special focus on the home it argues against a rational economic view of the consumer and emphasizes the significance of a more subtle understanding of private energy use the article approaches the challenges of reducing private energy consumption by analysing the domestication of the home and discusses everyday life activities as well as the phenomenon of rebuilding and redecorating by using the concept of domestication the article challenges the linear understanding of technological as well as behavioural change private energy consumption is part of a complex network and it is necessary to understand this network in order to achieve a more permanent reduction

energy production system optimization evidence from pakistan abstract the ongoing energy crisis in pakistan and the dependency on thermal electricity generation has contributed to the necessity to optimize energy production system the expensive thermal electricity and inability to recover its cost gives unprecedented rise to the electricity tariffs in this study optimization of the energy production system has been performed using linear programing model as the high cost of electricity generation has been found as the root cause of energy crises the objective function of the proposed model is cost minimization that will also reduce the circular debt specifically it has examined the optimum proportion of energy production from each available source under two different scenarios the first scenario considers that the existing system should be used at its maximum capacity in the second scenario seventy percent utilization of power plants has been examined the second scenario summarizes the optimum mix of energy production which minimizes the cost of electricity production the differential cost that is payable by the government as a subsidy is also compensated similarly it reduces circular debt that is a bottleneck between power generation companies and oil supply companies thus the proposed model has a tendency to minimize the cost of energy production and further reduce circular debt as well as the burden of a subsidy on the government the study specifies the problems confronting pakistan s energy sector and identifies the key elements of a potential policy response to address the country s severe power crisis

financial impact of energy efficiency under a federal combined efficiency and renewable electricity standard case study of a kansas super utility abstract historically local state and federal policies have separately promoted the generation of electricity from renewable technologies and the pursuit of energy efficiency to help mitigate the detrimental effects of global climate change and foster energy independence federal policymakers are currently considering and several states have enacted a combined efficiency and renewable electricity standard which proponents argue provides a comprehensive approach with greater flexibility and at lower cost we examine the financial impacts on various stakeholders from alternative compliance strategies with a combined efficiency and renewable electricity standard ceres using a case study approach for utilities in kansas our results suggest that an investor owned utility is likely to pursue the most lucrative compliance strategy for its shareholders one that under invests in energy efficiency resources if a business model for energy efficiency inclusive of both a lost fixed cost recovery mechanism and a shareholder incentive mechanism is implemented our analysis indicates that an investor owned utility would be more willing to pursue energy efficiency as a lower cost ceres compliance strategy absent implementing such a regulatory mechanism separate energy efficiency and renewable portfolio standards would improve the likelihood of reducing reliance on fossil fuels at least cost through the increased pursuit of energy efficiency

taxation of capital gains on owner occupied homes the paper compares taxation on realization with taxation on accrual in the context of owner occupied housing it considers a model where the utility a household derives from housing relative to other consumption varies over the life cycle as there are sizeable transaction costs housing consumption will not even in the absence of taxes be adjusted continuously but at discrete intervals the focus of the paper is on tax effects on the length of these intervals the following results are shown u taxing true economic appreciation at the same rate as imputed rental income and other capital income will lead to a shortening of the intervals if the capital gains are taxed on accrual an increase in this tax rate holding other rates constant will lead to a shortening of the intervals if the capital gains are taxed only as they are realized an increase in this tax rate holding other rates constant may either lead to a lengthening or a shortening of the holding period shortening is more likely if transaction costs are large whereas lengthening will occur if the rate of price increase is high

technology invention and diffusion in residential energy consumption a stochastic frontier approach traditional large appliances absorb a large share of residential electricity consumption and represent important targets of energy policy strategies aimed at achieving energy security despite being characterized by rather mature technologies this group of appliances still offers large potential in terms of efficiency gains due to their pervasive diffusion in this paper we analyse the electricity consumption of a set of four traditional white goods in a panel of ten eu countries observed over 21 years 1990 2010 with the aim of disentangling the amount of technical efficiency from the overall energy saving the technical efficiency trend is modelled through a set of technology components representing both the invention and adoption process by the means of specific patents weighted by production and bilateral import flows which allows to overcome the rigid stochastic frontier framework in modelling the effect of technical change our results show that the derived energy demand and inefficiency trends are both related to changes in the amount of available technology embodied in energy efficient appliances the effect is significant both in its domestic and international components and suggests an active role of innovation and trade policies for achieving efficiency targets which directly impact the amount of electricity consumed by households

unexpected inflation and bank stock returns the case of france 1977 1991 abstract this paper evaluates the impact of unexpected inflation on the stock returns of a sample of french banks it offers an empirical test of theories that have predicted an impact of inflation on the stock returns of banks the paper complements a large literature that has focused exclusively on the impact of unexpected interest rates the analysis provides empirical support to the hypothesis that in periods of volatile inflation there exists an inflation risk factor which is independent of the well documented interest rate factor

risk the financial market and macroeconomic equilibrium growing recognition of the importance of stock market phenomena to the real economy underscores the need for models linking exogenous uncertainty asset market performance and the rest of the economy in an optimizing framework without certainty equivalence this paper constructs a three agent model with continuous time stochastic variables uncertain private production and government expenditure and forward looking rational agents the growth rate of output physical capital accumulation financial asset returns and uncertain inflation are determined as functions of the exogenous uncertainty in the economy analysis of the model finds that increased risk associated with government policy often reverses in an explainable way the conventional comparative static predictions of nonstochastic macro models

stock returns and inflation with supply and demand disturbances we account for the relation between stock returns and inflation with two independent disturbances supply shocks and demand shocks supply shocks reflect real output shocks and cause a negative relation between stock returns and inflation while demand shocks are mainly due to monetary shocks and generate a positive relation between stock returns and inflation we show both theoretically and empirically that the stock return inflation relation varies over time and across countries depending on the relative importance of the two types of shocks our empirical evidence is based on pre and postwar periods in the united states as well as the postwar period in the united kingdom japan germany article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

tenure choice and the demand for housing this paper deals with the estimation by means of nonlinear methods of preference parameters from observation of behaviour in housing markets it differs from previous work on housing market behaviour in several important aspects first it treats the choice of tenure mode that is whether to rent or own and the housing consumption decision as a joint decision second it explicitly uses the same behavioural model in analysing these discrete and continuous elements of housing market behaviour third it allows for an analysis of the role of capital market imperfections and discriminatory practices in constraining housing market decisions

housing prices and tenure choice with asymmetric taxes and progressivity abstract this paper studies the effects of tax schedule changes on prices and tenure choice in the housing market it is shown that given the present asymmetric treatment of owner occupants vs renters an increase in the degree of progressivity is likely to lead to an increasein the prices of both owner occupied and rental housing a numerical example indicates that the effects may be quite large equilibrium prices are calculated based on the actual swedish income tax schedules for 1971 and 1979 according to these simulations the tax changes that took place between these years caused the price of owner occupied houses to increase by around 30 percent and the rent level to increase by 2 or 3 percent

the socio technical barriers to solar home systems shs in papua new guinea choosing pigs prostitutes and poker chips over panels this study explores the socio technical barriers to solar home systems shs in papua new guinea the authors collected primary data through semi structured research interviews conducted over the course of february 2010 april 2010 respondents included government officials financiers planners commercial distributors and companies teachers and rural villagers in addition to members of civil society academics consultants and trainers these interviews were supplemented with site visits to port moresby goroka and madang and field research in the villages of akameku asaroka lufa kundiawa okifa simbu and talidig the study draws from these interviews and visits to discuss four types of barriers technical barriers relate to substandard equipment and logistical problems economic barriers include high rates of poverty misconceptions about the role of currency and lack of financing political barriers include poor institutional capacity and a government commitment to fossil fueled grid electrification social barriers encompass unrealistic expectations about what shs can provide along with jealousy theft vandalism and unfamiliarity with solar technology

money and asset prices with uninsurable risks abstract we present a theory of differences of liquidity across assets based on an endogenous ranking of assets as media of exchange arising from their relative quality as hedging devices when assets have two distinct roles as intertemporal media of exchange and hedging devices buyers have generically a strict preference for paying sellers with the asset which is the relative better hedging device for sellers the consequence of this preference is that there are three monetary policy regimes and these regimes differ in which assets serve as media of exchange whether assets carry a liquidity premium and in the impact that monetary policy has on asset prices

stationary sunspot equilibrium in a cash in advance economy abstract in this paper we demonstrate the existence and uniqueness of a class of stationary sunspot equilibria in the cash in advance economy of lucas and stokey sunspots affect not only the price of money but prices of productive assets assets prices may fluctuate forever below their market fundamentals

dynamic aspects of consumer decisions in housing markets abstract in this study we estimate a model of the joint tenure length of stay and consumption level choices of families in the housing market this is the first attempt we know of to do this type of estimation the data pertain to a single residence spell per household from the panel study of income dynamics wealthier and better educated families were found to be more mobile in terms of housing consumption after accounting for tenure choice and controlling for planned length of stay renters and owners were found to have similar demand function relationships in terms of the impacts of socioeconomic variables this confirms the notion that renters and owners are not differentiated by housing choice but simply in life cycle circumstances as to when it is optimal to own or rent

macroeconomic determinants of stock volatility and volatility premiums how does stock market volatility relate to the business cycle we develop and estimate a no arbitrage model and find that i the level and fluctuations of stock volatility are largely explained by business cycle factors and ii some unobserved factor contributes to nearly 20 to the overall variation in volatility although not to its ups and downs instead this volatility of volatility relates to the business cycle finally volatility risk premiums are strongly countercyclical even more than stock volatility and partially explain the large swings of the vix index during the 2007 2009 subprime crisis which our model captures in out of sample experiments

the relation between stock prices and inflationary expectations the international evidence this paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971 80 the fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world using interest rates as a proxy for expected inflation our data provide consistent support for the geske and roll model whose basic hypothesis is that stock price movements signal negative revisions in inflationary expectations finally a weak real interest rate effect was found for some of these countries

conceptualizing the acceptance of wind and solar electricity drawing from research interviews and the academic literature this article conceptualizes the conditions that promote investor confidence and the social acceptance of wind and solar sources of electricity it explores the factors influencing the acceptance of commercial wind turbines in denmark and india and residential solar panels in germany and the united states the article begins by justifying its selection of case studies and explaining the methodology behind its research interviews and field visits it then summarizes some of the key findings in recent surveys of public attitudes and market acceptance concerning renewable energy with a focus on why some investors and communities reject wind and solar systems whereas others rapidly approve and adopt them the article proposes that acceptance has multiple dimensions socio political community and market that must be met holistically in order for investors and users to embrace renewable energy the article argues that acceptance hinges upon the prevalence of nine factors the lack of such factors creates environments where they are rejected the theory is tested against four case studies that explore the forces driving renewable energy in denmark germany india and the united states

taxing residential housing capital this paper discusses the main aspects of the taxation of housing drawing on general principles of optimal taxation it focuses on the role of the property tax in achieving neutrality between rental and owner occupied housing assuming that landlords are taxed according to a neutral profits tax it follows that the property tax should be based on the rate of interest the paper discusses how the tax rate could be adjusted to account for the lack of effective taxation of capital gains the double taxation of dividends and the differences in the cost of labour between rental and owner occupied housing in most oecd countries the combined effect of the different housing taxes amounts to a tax subsidy to owner occupied housing it is demonstrated how this subsidy has been reduced in sweden as in many other countries in the past decade as a result of tax reforms and a lower rate of inflation the subsidy has effects on consumption patterns saving capital accumulation the distribution of welfare across gener

consumer preferences and willingness to pay for compact fluorescent lighting policy implications for energy efficiency promotion in saint lucia this article examines consumer willingness to pay for energy saving compact fluorescent light bulbs using the results of a stated preferences study conducted in the caribbean island nation of saint lucia geographic location low income status and age are found to affect willingness to pay for compact fluorescent lighting while higher income status and other demographic variables appear to have minimal or no significant impacts energy efficiency knowledge is associated with increased willingness to pay for energy efficient bulbs and with increased use of compact fluorescent lighting contrary to theoretical expectations past purchase of compact fluorescent bulbs is found to have no impact on self reported willingness to pay we hypothesize that this null result is due to the recent emergence of low cost low quality compact fluorescent bulbs in the saint lucian lighting market which may be negatively influencing consumers preferences and expectations regarding energy efficient lighting findings support the argument that government sponsored education and subsidy programs will likely result in increased use of energy saving technologies in saint lucia but such behavioral changes may not be sustained in the long run unless low quality bulbs the lemons of the compact fluorescent lighting market can be clearly identified by consumers

an overview of incentive policies for the expansion of renewable energy generation in electricity power systems and the brazilian experience abstract energy production from renewable sources is already a reality in many countries and with that different strategies for incentivizing investments in renewable energy generation have been proposed and used over the years in this study long term policies that have been applied in several countries such as feed in tariffs shares with commercialization of certificates auctions and net metering are overviewed and discussed the main advantages and disadvantages of these incentive strategies are emphasized focusing on applications some of these strategies that have already been applied in brazil are analyzed in greater depth emphasizing the potentialities and fragilities of these mechanisms observed within the country even though it is a country that stands out in relation to other latin american countries regarding electricity generation from non hydro renewable sources brazil still faces barriers that prevent a utilization compatible with its potential moreover the trend for renewable sources such as wind and solar power is to represent an energy capacity reserve to cover hydrological risks and also to contribute to a distributed generation spread through electricity distribution networks

asset prices liquidity and monetary policy in an exchange economy i formulate a model in which money coexists with equity shares on a risky aggregate endowment agents can use equity as a means of payment so shocks to equity prices translate into aggregate liquidity shocks that disrupt the mechanism of exchange i characterize a family of optimal monetary policies and find that the resulting equity prices are independent of monetary considerations i also study a perturbation of the family of optimal policies that targets a positive constant nominal interest rate and find that in this case the real equity return includes a liquidity return that depends on monetary considerations

characterizing the policy mix and its impact on eco innovation a patent analysis of energy efficient technologies abstract this paper provides an empirical investigation of the role played by selected characteristics of the policy mix in inducing innovation in energy efficiency technologies an original dataset covering 23 oecd countries over the period 1990 2010 combines the full set of policies in the energy efficiency domain for the residential sector with data on patents applied over the same period in this specific technological sector the econometric results suggest that when the policy mix is characterised by a more balanced use in demand pull and technology push instruments its positive effects on eco innovation tend to be greater moreover a more comprehensive policy mix is shown to be able to enhance innovation activities for the generation of new energy efficient technologies however the simple addition of an indiscriminate number of simultaneous policy instruments may reduce policy mix effectiveness finally the empirical findings confirm previous evidence on the importance of policy spillover effects and suggest that policy similarity between countries may represent an important aspect to be accounted for in policy mix design

money and asset prices in a cash in advance economy an asset pricing model with money introduced via a cash in advance constraint is presented the monetary velocity is variable hence money demand does not obey the trivial quantity equation the effects of disturbances in output and money growth on real balances the price level and interest rates are examined monetary policy has effects on real asset prices the fisher relation and the premium on nominal bonds are discussed the precise role of the timing of information and transactions for properties of price levels and interest rates are clarified

inflation and real stock returns revisited i introduction this article empirically reinvestigates the relationship between real stock returns and inflation according to fisher 1930 1 in an efficient market real stock returns should reflect expectations only about real factors such as growth in output and time preference of savers such that real stock returns and inflation should vary independently in other words on average investors are fully compensated for erosions in purchasing power over time however this so called generalized fisher hypothesis has received little empirical support while kaul 1990 boudoukh and richardson 1993 solnik and solnik 1997 madsen 2005 and ryan 2006 find positive or weakly positive correlation between stock returns and inflation most empirical studies including nelson 1976 fama 1981 1983 geske and roll 1983 gultekin 1983 kaul 1987 and solnik 1983 uncover a negative effect of inflation anticipated and or unanticipated on real or nominal stock returns these apparent inconsistencies between the data and the predictions of economic theory have been termed as the stock return inflation puzzle and cited as evidence of monetary nonsuperneutrality or irrationality and market inefficiency 2 to reconcile the seemingly conflicting contributions danthine and donaldson 1986 provide a rational expectations equilibrium model in which a negative relation between stock returns and inflation arises from non monetary sources e g a real output shock and a positive relation is driven by purely monetary sources stulz 1986 marshall 1992 and bakshi and chen 1996 also assert that stock returns may be negatively correlated with inflation especially when the source of inflation is related to nonmonetary factors evidently hess and lee 1999 khil and lee 2000 and lee 2003 find that while monetary shocks drive a positive correlation real fiscal or real output shocks result in a negative correlation between stock returns and inflation from a different perspective kaul 1987 1990 argues that the relation between these two variables depends on both the money demand and the money supply specifically while the combination of money demand effects with a countercyclical monetary response accentuates a negative correlation money demand shocks along with a procyclical monetary response lead to a neutral or positive correlation between real stock returns and inflation similar arguments can be found in day 1984 kaul and seyhun 1990 boudoukh richardson and whitelaw 1994 and gallagher and taylor 2002 and are supported by compelling empirical evidence see e g kim 2003 lee 1992 as an alternative this article models the real stock return inflation relationship as intrinsically dynamic explicitly distinguishing between the short run and the long run such a distinction is crucial because imperfect information rigidity and or contractual obligations are more prevalent in the short run than in the long run in that sense the response of real stock returns to inflation could differ in the short run versus long run moreover we assess the long and short run impacts of inflation uncertainty on real stock returns as argued the real costs of inflation are associated with its uncertainty greater inflation uncertainty resulting from higher inflation may lead to economic inefficiency lower real investment and unemployment thereby reducing economic growth thus it is interesting to see if there are independent effects of inflation uncertainty on real stock returns both in the short run and in the long run in so doing this article uses an innovative econometric technique to explore the long and short run relationships between real stock returns and inflation both anticipated and unanticipated and the relationships with inflation uncertainty it departs from earlier work and complements recent evidence in at least three aspects

evolving theories of sustainability and firms history future directions and implications for renewable energy research abstract sustainability has become a critical perspective in managing firms via a holistic approach by considering economic environmental and social dimensions of firms with the rising significance of sustainable development the theories of sustainability in firms have evolved during the past six decades this article offers a critical review of the evolving theories linking sustainability to firms and discusses their implications for future renewable energy research the relationships among different theories are critically analysed and the directions for future research are discussed the paper shows that the main theories linking sustainability to firms in a chronological order are 1 corporate social responsibility 2 stakeholder theory 3 corporate sustainability and 4 green economics currently various innovative approaches and new theories emerged such as co evolution theory and multi level perspective reflecting three directions of theory development namely 1 shifting from what to how 2 growing use of interdisciplinary approach and 3 towards broader systems renewable energy studies associated with firms and future research opportunities in this area are also critically analysed the comprehensive review offered in this paper provides a useful reference for policy makers corporate managers and researchers interested in corporate sustainability and renewable energy related studies

the equity premium in brock s asset pricing model abstract in this paper we combine dynamic programming methods with projection methods for solving stochastic growth models as an application of these methods we solve brock s asset pricing model with a variety of parameterizations we focused on finding parameterizations that result in an equity premium that is high relative to the variation in consumption we show both analytically and numerically that the equity premium can be higher in a production based asset pricing model than it is in the consumption based asset pricing model even when the real output level is the same in both models

monetary uncertainty in discrete time utility of money models abstract in a discrete time model higher variability of the future money supply affects current macroeconomic variables when beginning of period money is the argument of utility but not when end of period money is the effect is through the existence of a precautionary money demand

policies and market factors driving wind power development in the united states abstract in the united states there has been substantial recent growth in wind energy generating capacity with growth averaging 24 percent annually during the past five years about 1700 mw of wind energy capacity was installed in 2001 while another 410 mw became operational in 2002 during 2003 development activity has remained strong with an estimated 1600 mw of capacity installed with this growth an increasing number of states are experiencing investment in wind energy projects currently about half of all states host at least one wind power project this paper explores the key factors at play in the 12 states in which a substantial amount of wind energy capacity has been developed or planned some of the factors that are examined include policy drivers such as renewable portfolio standards rps federal and state financial incentives as well as market drivers such as consumer demand for green power natural gas price volatility and wholesale market rules

tax reform and housing demand the distribution of welfare gains and losses abstract we study distributional effects of a recent reform of the swedish system of income taxation which affects the price of owner occupied housing in calculating the welfare effects we account both for the non linearities of the income tax schedule and the dichotomous choice aspect of housing demand to own or to rent small and rosen 1981 have shown how the standard harberger type approximation formulae can be adapted to handle discrete choices and we modify their analysis for a non linear budget constraint

hybrid modeling to support energy climate policy effects of feed in tariffs to promote renewable energy in portugal abstract feed in tariffs have been the main policy instrument applied in portugal for the promotion of electricity produced from renewable energy sources under the eu directives on energy and climate regulation in this paper we provide an empirical impact assessment of the economic and environmental effects of portugal s fits policy to promote res e generation impact assessment of policy instruments plays a crucial role on decision making process for numerical simulations we make use of a hybrid top down bottom up general equilibrium modeling approach which represents a reliable tool to analyze the complex interactions between economic energy and environmental issues related to energy policies numerical simulations confirm the empirical evidence that the fits policy implemented by portugal was both an effective and a cost efficient way to increase the generation of electricity from renewable energy sources and thus to achieve the national res e target of 45 in 2010 results show relatively modest macroeconomic impacts indicating potentially low economic adjustment costs from an environmental perspective the deployment of renewable energy source results in significant carbon emissions reductions

exchange rate volatility the role of real shocks and the velocity of money the effects of stochastic output shocks on the behavior of ex change rates and nominal price levels is studied within the context of a two country cash in advance model the analysis of this model in contrast to the existing cash in advance literature demonstrates that exchange rates can be more volatile than price levels even though agents elasticity of substitution between foreign and domestic goods is greater than one half this possibility arises when output shocks are autocorrelated and are due to revisions in expectations that affect the terms of trade and or the velocity of money

sticky goods prices flexible asset prices monopolistic competition and monetary policy a monetary general equilibrium asset pricing model with sticky goods prices is developed goods prices are set by monopolistically competitive firms that maximize stock market value equilibria with underutilization of resources excess capacity in some states result in contrast to previous monetary asset pricing models the degree of competition affects capacity utilization monetary policy can affect output and resource utilization in addition to real asset prices depending upon the amount of information available to the monetary authority

are stocks a good hedge against inflation evidence from emerging markets theory suggests that equities are a good hedge against inflation however most of the empirical evidence for industrialized economies suggests that the relationship between stock returns and inflation is negative one explanation is the negative correlation between inflation and real output growth this paper examines the relationship between inflation and stock returns for ten important emerging stock market esm markets namely chile mexico brazil argentina thailand s korea malaysia hong kong philippines and turkey during the 1990s to anticipate the results the relationship between stock returns and inflation for the whole sample period is positive and statistically significant for three of the sample esms while it is positive but statistically insignificant for a further three only for one esm is the relationship negative and statistically significant this result may be due to the role of money and the positive relationship between consumer prices and output

transaction costs capital gains taxes and housing demand abstract the paper considers the effect of transaction costs particularly in the form of capital gains taxes on the aggregate demand for owner occupied housing the framework is an overlapping generations model where consumers can avoid the transaction costs taxes by keeping the same house for both periods of life the first part of the paper analyzes the consumer s choice problem it distinguishes between costs that are fixed irrespective of the size of the house bought or sold and costs such as capital gains taxes that are related to the house value it is shown that higher transaction costs have lock in effects inducing consumers to keep the same house for both periods also it is found that under a wide variety of circumstances the amount of housing demanded will increase as the household is being locked in finally the paper looks at the effects on aggregate demand from an increase in capital gains taxes it is shown that an increased rate of taxation decreases demand for low tax rates but for high tax rates when lock in effects become important one generally gets the opposite effect high tax rates tend to increase housing demand

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

do policy mix characteristics matter for low carbon innovation a survey based exploration of renewable power generation technologies in germany abstract policy mixes may play a crucial role in redirecting and accelerating innovation towards low carbon solutions thus addressing a key societal challenge towards this end some argue that the characteristics of such policy mixes matter greatly yet with little empirical evidence backing up such claims in this paper we explore this link between policy mix characteristics and low carbon innovation using the research case of the transition of the german electricity system towards renewable energy our empirical insights are based on an innovation survey administered to german manufacturers of renewable power generation technologies which builds on the community innovation survey for our purposes we adjusted the survey to better capture companies perceptions of policy mixes employing a bivariate tobit model we find evidence that companies perceptions regarding the consistency and credibility of the policy mix are positively associated with their innovation expenditures for renewable energies and this positive link intensifies when considering the mutual interdependence of these policy mix characteristics in contrast neither the comprehensiveness of the instrument mix nor the coherence of policy processes were found to be related to innovation expenditures overall these findings suggest that future research on low carbon and eco innovation should pay greater attention to the characteristics of policy mixes rather than focusing on policy instruments only finally our findings indicate a need to consider how policy may be measured in innovation surveys to generate better informed policy advice regarding the greening of innovation

the emergence of equilibrium cycles in a monetary economy with a separable utility function abstract this paper analyzes the dynamic properties of the monetary economy when money held during the period induces some utility it is shown that the price level and real money balances may have chaotic dynamic paths even if the utility function is separable in real money balances and consumption a crucial point is that a constraint on the utility of money yields the wealth effect that inflation will reduce the real value of assets hence as in the overlapping generations model the conflict between substitution and wealth effects may cause globally stable periodic orbits as well as the complicated dynamics

inflation human capital and tobin s q a pervasive empirical finding for the us economy is that inflation is negatively correlated with the normalized market price of capital tobin s q and growth a dynamic stochastic general equilibrium model of endogenous growth is developed to explain these stylized facts in this model human capital is the principal driver of self sustained growth long run comparative statics analysis suggests that inflation diverts scarce time resource to leisure which lowers human capital utilization this impacts growth adversely and modulates capital adjustment cost downward resulting in a decline in tobin s q for the short run a tobin effect of inflation on growth weakens the negative association between inflation and q

renewable energy technology diffusion an analysis of photovoltaic system support schemes in medellin colombia abstract colombia s electricity mix is dominated by hydropower which constitutes over 65 percent of the installed capacity the country has important potential for introducing solar photovoltaic sources into its electricity generation mix given its high average annual insolation however there is a lack of incentives and support schemes for alternative renewable energy technologies this paper analyzes the diffusion of a photovoltaic system in colombia with a focus on medellin colombia s second largest city a diffusion model is constructed based on the classic bass diffusion theory where the adoption rate is a function of awareness raising campaigning and social interaction the model incorporates both subsidy and feed in tariff policies policy implementation scenarios and the effects of policy mixes are analyzed results show that a 50 percent subsidy for investment together with a usd 0 30 kwh feed in tariff rate jointly provide the highest marginal increase in diffusion rate however given the cheapness of the country s current hydroelectric resources photovoltaic system diffusion might remain a challenge for both the government and private sectors for the foreseeable future

sustainability performance for brazilian electricity power industry an assessment integrating social economic and environmental issues the increased pressure on companies to address sustainability issues has resulted in the development of several voluntary corporate sustainability integration approaches the array of existing approaches is large and overwhelming resulting in companies not understanding what corporate sustainability really means for their businesses considering environmental economic and social issues this paper aims at assessing the performance of the brazilian electricity power industry in terms of its sustainability performance an analysis of global reporting initiative gri indicators for the energy sector lead to an assessment of its sustainability performance by applying data envelopment analysis dea specified with a directional distance function ddf five scenarios were created i flexible weights ii triple bottom line iii social issues iv economic issues and v environmental issues with considering i flexibility weights almost all companies are efficient we also found a significant difference when we compared i with the other four scenarios ii iii iv and v taking into account the triple bottom line scenario ii the results indicate that companies were less efficient when compared with the flexible weights scenario i taking into account the last three scenarios iii iv and v only four companies were considered as providing top benchmarks in sustainability performance

effects of the swedish 1983 85 tax reform on the demand for owner occupied housing a microsimulation approach the effects of the swedish 1983 85 tax reform are analyzed with respect to the housing market a microsimulation model is used which takes into account the household s tenure choice owning vs renting as well as the quantity demanded conditional on the tenure choice the reform consists of a reduction in marginal tax rates and limitations on the deductibility of mortgage interest the simulations show that this will cause a general reduction in demand for owner occupied houses on a disaggregated level there will be an increase in the demand for small and medium sized houses while the demand for large units will fall sharply

policy mixes for sustainability transitions an extended concept and framework for analysis reaching a better understanding of the policies and politics of transitions presents a main agenda item in the emerging field of sustainability transitions one important requirement for these transitions such as the move towards a decarbonized energy system is the redirection and acceleration of technological change for which policies play a key role in this regard several studies have argued for the need to combine different policy instruments in so called policy mixes however existing policy mix studies often fall short of reflecting the complexity and dynamics of actual policy mixes the underlying politics and the evaluation of their impacts in this paper we take a first step towards an extended interdisciplinary policy mix concept based on a review of the bodies of literature on innovation studies environmental economics and policy analysis the concept introduces a clear terminology and consists of the three building blocks elements policy processes and characteristics which can be delineated by several dimensions based on this we discuss its application as analytical framework for empirical studies analyzing the impact of the policy mix on technological change throughout the paper we illustrate the proposed concept by using the example of the policy mix for fostering the transition of the german energy system to renewable power generation technologies finally we derive policy implications and suggest avenues for future research

sustainability performance disclosures the case of independent power producers abstract independent power producers ipps investing across borders represent a crucial sector that produces an adverse impact on greenhouse gas emissions ghg the main purpose of this study is to articulate issues pertinent to sustainability performance among contemporary ipps which seek funding from the capital markets a framework employing a sustainability performance scorecard is developed based on an interdisciplinary literature review that spans the fields of corporate finance financial reporting and sustainability by examining the sustainability performance as disclosed by three cross border ipps from the u s europe and the emerging economy of asia this comparative case study unveils the current weaknesses in comparability relevance and usefulness in disclosures among the ipps it points out potential information asymmetry to decision making of the primary stakeholders who seek to invest in renewable and sustainable energy while countering short termism over financial returns a concerted policy effort on disclosures about sustainability performance would be crucial to channeling effective private investments into the development of renewable and sustainable energy

complementarity and substitutability a review of state level renewable energy policy instrument interactions abstract this paper provides an extensive review of two streams of literature the first part of the review focuses on policy tools and their interrelationships and the second part focuses on the literature on the state renewable energy policy tools based on the reviews this paper investigates how policymakers choose a set of interrelated renewable energy policy instruments and identify under what conditions policy instruments complement or substitute we extend the political market framework by examining the influences of 1 administrative agencies on the supply side 2 interest groups on the demand side and 3 the policy induced problem situation changes on the adoption of state renewable energy policy tools building upon reviews of both policy tools and policy diffusion theories a set of hypotheses are advanced for state renewable energy policy interactions among public benefit fund pbf renewable portfolio standards rps and corporate tax incentive cti the hypotheses are tested by three event history models in which rps pbf and cti serve as dependent variables separately the complementary effects between previous use of rps and adoption of pbf between previous use of pbf and adoption of rps and between previous use of cti and adoption of rps are confirmed we also find support for the policy substitutability between previous use of cti and adoption of pbf

theory and estimation in the economics of housing demand the main purpose of this paper is to review recent theoretical and empirical developments in the economics of housing demand in particular we ask what is known concerning the permanent income elasticity of housing demand vis a vis the current or measured income elasticity what is known concerning price elasticities what is the appropriate functional form for housing demand equations what is the role of demographic variables what is known concerning dynamic aspects of housing demand what appear to be the major sources of bias in existing estimates of demand equations

a money demand function with output uncertainty monetary uncertainty and financial innovations in a general equilibrium framework incorporating the money in the utility function approach we show that output uncertainty and monetary uncertainty as well as output interest rates and financial innovations affect money demand the estimated long run relationships are consistent with our postulated relation but not with the conventional one our model delivers a high income elasticity consistent with cross sectional evidence and helps resolve m1 demand puzzles the model estimated in dynamic error correction form exhibits a good level of stability and forecastability providing little support for the recent de emphasis of monetary aggregates due to the instability of money demand

cross sectional estimation of a simultaneous model of tenure choice and housing services demand abstract in this paper we analyze the demand for housing services integrating into a single analysis a systematic treatment of several important conceptual and empirical issues our three major objectives are to 1 evaluate the empirical importance of the simultaneity between the tenure choice and consumption level decisions 2 analyze the relationship between household type and housing demand and 3 present new estimates of the parameters of housing demand which are based on detailed microdata in the process we derive and estimate overall income and price demand elasticities which incorporate the impacts of income and price on both the tenure choice and consumption level decisions

industry returns and the fisher effect we investigate the cross sectional relation between industry sorted stock returns and expected inflation and we find that this relation is linked to cyclical movements in industry output stock returns of noncyclical industries tend to covary positively with expected inflation while the reverse holds for cyclical industries from a theoretical perspective we describe a model that captures both i the cross sectional variation in these relations across industries and ii the negative and positive relation between stock returns and inflation at short and long horizons respectively the model is developed in an economic environment in which the spirit of the fisher model is preserved the fisher model states that expected nominal rates of return on assets should move one for one with expected inflation this belief is generally attributed to irving fisher s 1930 work on interest rates in particular to his view that the real and monetary sectors are causally independent in an apparent contradiction to the fisher hypothesis however it is a common empirical finding that stock returns are negatively related to both expected and realized inflation 1 this negative correlation is especially surprising for stocks which as claims against real assets should compensate for movements in inflation we provide two main contributions to the existing literature on the relation between stock returns and inflation the first contribution of the article is to provide a theoretical description of the cross sectional relation between stock returns and expected inflation we describe an asset pricing model that predicts cross sectional variation in the coefficients of expected inflation across various industry portfolios an interesting feature of the model is that it synthesizes some of the more palatable features of existing explanations of the negative relation between inflation and returns of special interest is the development of the model in a money neutral world so that the basic premise underlying fisher s work is maintained since most theoretical models of the

does inflation affect real behavior the case of housing an important tradition in economics is to assume that demand depends upon relative prices and is homogenous of degree zero for the most part this has been interpreted as meaning inflation changes in the price level leaves demand unchanged recent work by a number of economists has challenged this position for the case of housing demand two arguments have been made that inflation acting in concert with existing institutions alters the quantity of housing demanded and the decision to rent or own a house the first argument states that inflation and the standard fixed payment mortgage combine to reduce the size of the mortgage loan a household can obtain for the purpose of buying a home this works to reduce the quantity of owner occupied housing demanded given the importance of mortgage finance to the demand for owner occupied housing the second argument focuses on the inflation adjusted after tax cost of owner occupied housing it simply states that an increase in the rate of anticipated inflation of the general price level reduces the after tax cost of housing thus increasing the demand for housing and the demand for homeownership there has been little empirical testing of these two arguments the purpose of this paper is to formulate and estimate a model which will give an indication of the quantitative significance of the two arguments a housing demand equation and a tenure choice equation own versus rent are estimated using a sample of about 6000 households from the 1975 annual housing survey 10 the estimates suggest that inflation dampens housing demand and homeownership opportunity for most households even though the inflation adjusted after tax cost of owner occupied housing declines as inflation heats up the paper consists of six sections including the introduction section two examines the ways inflation affects housing choices in more detail the third section contains the specification of the econometric model that forms the basis of the study section four is a discussion of econometric problems and the data used the results of the estimates are discussed in the fifth section the paper concludes with a presentation of the major conclusions and policy implications of the study

nominal prices and interest rates in general equilibrium endowment shocks the outstanding problem of neoclassical monetary theory has been to determine the effect of changes in the money stock on nominal prices and interest rates the classic result is that in the absence of money illusion contracts fixed in nominal terms and other such impedimenta money is neutral thus a doubling of the money stock results in a doubling of the nominal price level and in no change in nominal interest rates except at most for a temporary liquidity effect while the price level is rising to its new level during the adjustment period the nominal interest rate might temporarily drop this neutrality result has conventionally been proved in a static framework in intertemporal models it is necessary to distinguish between static neutrality and dynamic neutrality if a model displays dynamic neutrality fluctuations in the money stock immediately induce a proportional change in the nominal price level and no change in nominal interest rates or any real variable this property is different from and stronger than static neutrality which in dynamic models states only that if the money stock at all dates is doubled so will be the price level at all dates the effects of exogenous shocks in the monetary growth rate on nominal prices and interest rates are analyzed a representative individual rational expectations framework is adopted and a demand for money is generated by entering money in the utility function the effects of monetary shocks on inflation and interest rates are shown to depend on the autocorrelation of the monetary growth rate for example under serial independence the inflation rate equals the monetary growth rate and the nominal interest rate is nonrandom while under positive negative autocorrelation the nominal interest rate is affected positively negatively by positive growth rate shocks i am grateful to the staff of the federal reserve bank of philadelphia to the finance groups at the university of southem california and virginia polytechnic institute and to c j lacivita dan peled john seater and jon sonstelie for valuable comments on earlier drafts

comparing the feed in tariff incentives for renewable electricity in ontario and germany the development of feed in tariff fit programs to support green electricity in ontario the green energy and green economy act of 2009 and germany the erneuerbare energien gesetz of 2000 is compared the two policies are highly comparable offering similar rates for most renewable electricity technologies major differences between the policies include the level of differentiation found in the german policy as well as the use of a price degression strategy for fit rates in germany compared to an escalation strategy in ontario the german renewable electricity portfolio is relatively balanced compared to ontario where wind power dominates the portfolio at the federal level canada does not yet have a policy similar to the european directive on renewable energy and this lack may impact decisions taken by manufacturers of renewable technologies who consider establishing operations in the province ontario s green energy and green economy act could be benefit from lessons in the german system especially with regard to degression of feed in tariff rates over time which could significantly reduce payments to producers over the course of a contract and in turn encourage greater competitiveness among renewable power providers in the future

fostering a renewable energy technology industry an international comparison of wind industry policy support mechanisms this article examines the importance of national and sub national policies in supporting the development of successful global wind turbine manufacturing companies we explore the motivations behind establishing a local wind power industry and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders this is done through a cross country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries we find that in many instances there is a clear relationship between a manufacturer s success in its home country market and its eventual success in the global wind power market whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market which in turn will be influenced by the annual size and stability of that market consequently policies that support a sizable stable market for wind power in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally are most likely to result in the establishment of an internationally competitive wind industry

sources and propagation of international output cycles common shocks or transmission abstract this paper studies the generation and transmission of international cycles in a multi country model with production and consumption interdependencies two sources of disturbance are considered and three channels of propagation are compared technology disturbances which are mildly correlated across countries are more successful than government expenditure disturbances in reproducing actual data the presence of a common component to the shocks and of production interdependencies appear to be crucial in quantitatively matching the properties of the data

sustainable energy policy for asia mitigating systemic hurdles in a highly dense city abstract greenhouse gas emission ghg has been increasingly a sensitive issue that is across border and impacting global public interests while the use of renewable energy technology is perceived as a means to enable delivery of emission free solutions its penetration into the energy market has not been timely and significant enough as projected in prior studies this article aims to illustrate some of the critical hurdles as the policy makers start formulating environmentally friendly energy consumption means for the public in asian economies in particular through analyzing the characteristics in the case of hong kong the authors unveil the challenges for this highly dense city to reach a landscape of alternative energy resources for its transition into a sustainable economy education and engagement with the public about a sustainable future alignment of stakeholders economic interests and absorption capacity of emerging technologies are argued as the three main challenges and initiatives in mitigating the underlying systemic hurdles that remain to be overcome observing the current responses to the externalities by the policy makers in hong kong this study articulates the critical challenges to mitigate these specific systemic hurdles embedded in the existing infrastructure of a highly dense city possible mitigating measures to enable deployment of integrative sustainable energy solutions in dealing with climate change are discussed

comparative dynamics of an equilibrium intertemporal asset pricing model this paper uses recursive competitive theory to develop a general equilibrium asset pricing model in this framework all prices and rates of return are endogenously determined thus enabling us to analyze the effects of changes in preferences technological uncertainty and expectations on the structure of security prices in particular we focus on how the market risk premium varies with changes in the underlying economic environment an issue which other asset pricing models have chosen not to address

modes of governance for municipal energy efficiency services the case of led street lighting in germany energy efficiency retrofits are often impeded by high perceived investment risks long payback periods and a lack of skills at the municipal level these issues are particularly pronounced as procuring implementing and managing retrofits can exceed existing municipal governance capacities the diffusion of municipal led street lighting as a replacement for conventional lighting serves as an example this paper argues that technological e g complexity and maturity economic e g selling services vs products and financing costs institutional e g property situation and contracts and competency barriers to retrofitting e g lack of measurement capacity and qualified facilitators translate into transaction costs we develop a taxonomy of appropriate modes of municipal retrofitting governance based on transaction costs economics the findings indicate that more market based solutions energy performance contracts in particular can facilitate the procurement of innovative energy efficiency retrofitting solutions and associated investments among municipalities if neutral tenders open book accounting municipal ownership and intermediary organisations allow municipalities to choose appropriate governance structures for particular technologies and retrofits
