the dynamic cost and persistence of asset inequality in an agrarian economy abstract a growing literature suggests that asset inequality can be economically costly in the presence of agency costs that constrain labor and capital markets unclear in this literature is whether asset markets and optimal individual accumulation of self finance capacity suffice to eliminate costly inequality over time this paper uses numerical dynamic programming methods to explore this question with a model of an initially inegalitarian agrarian economy while an egalitarian asset distribution emerges over time the process involves sufficiently great productivity losses along the way that a redistributive policy could improve on the market s performance by both equity and efficiency criteria

the relevant market for production and wholesale of electricity in the nordic countries an econometric study we apply cointegration analysis to daily averages of nord pool prices covering the period 2001 2007 in order to empirically characterize the geographical dimension of the relevant market for production and wholesale of electricity we reach the following econometric conclusions i price areas finland sweden and norway 3 unambiguously belong to the same relevant market ii denmark 2 belongs to this same market except for the subsample 2004 2007 iii norway 1 and denmark 1 define separate markets on their own we find that the stochastic trends in nord pool prices originate in countries abundant in capacity to generate hydro power

public goods as characteristics of non market commodities in benefit cost analysis it is useful to model public goods as the quality of privately consumed nonmarketed goods this strategy is often pursued in valuing environmental amenities the theoretical foundations of this model have not been fully developed in this paper comparative statics results are derived for quality changes of nonmarket goods the results reveal some common misconceptions about welfare measurement of quality changes conditions are presented for a quality induced change in the marshallian consumer surplus of the nonmarket good to approximate the true compensated welfare measure the conditions are equally necessary for obtaining exact welfare measures copyright 1993 by royal economic society

comment on cameron s censored logistic regression model for referendum data abstract t a cameron a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression j environ econom management 15 355 379 1988 presents what she terms a new paradigm for interpreting referendum data derived from contingent valuation surveys for nonmarket resources we show that since her model is a reparameterization of the usual logistic regression model asymptotic standard errors can be derived for the maximum likelihood estimators of the parameters in either model from the other we also argue that computational convenience in deriving demand relationships or elasticities depends more on the choice of welfare measure than on the choice of a parameterization

membership desertion as an adjustment process on honduran agrarian reform enterprises thus incapable of improving rural productivity or solving serious distributional problems in the honduran debate pervasive membership desertion from agrarian reform enterprises is frequently cited by reform critics as empirical evidence of inefficiency and decline within the reform program enterprises this desertion is generally blamed on various collective action problems of cooperative organization such as organizational infighting labor shirking and corruption 2 even the agrarian reform proponents within honduras seem to accept membership desertion as evidence of reform sector inefficiency and retreat to arguments about the social and political benefits of reducing rural tensions or the efficiency prospects of dividing reformsector lands into individual parcels these tactics are understandable given the compelling logic behind membership desertion as an indicator of enterprise inefficiency in essence the argument is that if the rural landless who are the poorest of the rural poor struggle long and hard for access to land only to abandon these cooperative enterprises in large numbers then the viability of these enterprises as production units must be highly suspect 3 the only task that remains for reform critics then is to cite recent estimates by the honduran national agrarian institute and the u s agency for international development usaid of the 20 40 membership decline in the 2 400 agrarian reform enterprises incorporated in honduras between 1968 and 1984 4 and a key argument about the efficiency and equity failure of the honduran agrarian reform is complete

public support for reducing us reliance on fossil fuels investigating household willingness to pay for energy research and development abstract in order to reduce future dependence on foreign oil and emissions of co2 how much would us households be willing to pay annually to support increased energy research and development r d activities designed to replace fossil fuels does it matter whether the r d includes nuclear energy options we explore these questions using data from a unique set of national telephone and internet surveys using a national advisory referendum format the contingent valuation method is applied to estimate annual household willingness to pay wtp for us household support of a national energy research and development fund erdf for investments in energy sources not reliant on fossil fuels while accounting for the level of un certainty in voting responses the wtp modeling includes a comparison of both classic maximum likelihood estimation mle and bayesian analysis evidence indicates that mle and bayesian analysis achieve similar statistical inference while the bayesian analysis provides a narrower confidence interval around estimated wtp

some consequences of temporal aggregation in empirical analysis i derive the generating mechanism of a temporally aggregated process when the disaggregated one belongs to the vector autoregressive integrated moving average class i then study the effects of temporal aggregation on a set of characteristics of usual interest such as exogeneity causality cointegration and common features an empirical example with canadian interest rates illustrates the main issues

access to capital and agrarian production organisation there are two problems both universal that entrepreneurs in any economy must contend with firstly an agent generally has access only to a limited amount of working capital secondly workers hired by an agent are subject to moral hazard and this necessitates their supervision this paper models for an agrarian economy the constraints imposed on entrepreneurs activities by these two problems and endogenously determines the various organisational forms of production as well as the allocation of resources that will obtain with a simple model we endeavour to explain a diverse set of empirical observations pertaining to the less developed countries in terms of the general processes that determine the distribution of income among the various agents and the hierarchical relationships that develop among them agricultural production typically involves a period of several months between the time the inputs are purchased and the time the output is marketed access to working capital and hence to the credit market thus plays an important role in a farmer s production decisions the distribution of access to credit in turn tends to be an important determinant of income distribution in poor agrarian economies credit is invariably rationed according to the ability to offer collateral the amount of working capital a farmer can mobilise therefore depends on the amount of land he owns which is often a good proxy for his overall wealth and thus his ability to offer collateral further since hired hands have a propensity to shirk they need to be supervised and therefore the

contractual structure and wealth accumulation can historical wealth distributions affect long run output and inequality despite rational saving convex technology and no externalities we consider a model of equilibrium short period financial contracts where poor agents face credit constraints owing to moral hazard and limited liability if agents have no bargaining power poor agents have no incentive to save poverty traps emerge and agents are polarized into two classes with no interclass mobility if instead agents have all the bargaining power strong saving incentives are generated the wealth of poor and rich agents alike drift upward indefinitely and history does not matter eventually d31 d91 i32 o17 q15

the theoretical structure of producer willingness to pay estimates this article analyzes the theoretical underpinnings of producer willingness to pay wtp for new inputs in addition to conceptualizing the producer wtp function we derive its comparative statics and show how these properties can be used to estimate quantities demanded or supplied and price elasticities we also discuss implications of the comparative statics

consumption versus asset smoothing testing the implications of poverty trap theory in burkina faso abstract despite solid theoretical foundations for the notion that poor borrowing constrained households will intertemporally manage assets to smooth consumption the consumption smoothing hypothesis has not always withstood empirical scrutiny this paper reassesses the intertemporal asset management problem with a poverty trap model and shows that we would expect to see asset smoothing not consumption smoothing in the neighborhood of critical asset levels at which optimal accumulation behavior bifurcates we then employ threshold estimation techniques to empirically confirm the co existence of consumption and asset smoothing regimes using a household panel data set from west africa households above the estimated threshold almost completely insulate their consumption from weather shocks whereas those below the threshold do not these results not only indirectly provide evidence of the existence of poverty traps but also speak to the level and incidence of the costs of uninsured risk

combining revealed and stated preference data to estimate the nonmarket value of ecological services an assessment of the state of the science this paper reviews the marketing transportation and environmental economics literature on the joint estimation of revealed preference rp and stated preference sp data the rp and sp approaches are first described with a focus on the strengths and weaknesses of each recognizing these strengths and weaknesses the potential gains from combining data are described a classification system for combined data that emphasizes the type of data combination and the econometric models used is proposed a methodological review of the literature is pursued based on this classification system examples from the environmental economics literature are highlighted a discussion of the advantages and disadvantages of each type of jointly estimated model is then presented suggestions for future research in particular opportunities for application of these models to environmental quality valuation are presented

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

low energy efficiency in rental properties asymmetric information or low willingness to pay abstract asymmetric information may explain low energy efficiency in rented properties energy ratings while a solution to the information problem will only lead to higher efficiency levels if renter s willingness to pay wtp exceeds landlord s investment costs using a sample of renters from one university this paper estimates this wtp using a discrete choice experiment where respondents choose from a hypothetical set of single bedroom apartments that differ according to a number of attributes including the energy rating results show that there is a strong disutility associated with the least efficient properties and that renters will pay significantly more for efficiency improvements at the lower end of the efficiency scale importantly our wtp estimates are calculated in a setting where respondents were informed about the energy rating system prior to choosing and where the rating was shown for every property therefore in order to maximise the impact of energy rating systems policymakers are encouraged to ensure that both these informational characteristics are in place

testing for temporal reliability in contingent valuation with time for changes in factors affecting demand we develop a temporal reliability test of the contingent valuation method separate random samples were administered the same telephone survey five years apart in the retest respondents have less favorable attitudes toward the environment given this result a temporally reliable contingent valuation would find lower willingness to pay we find that the estimates are temporally reliable after accounting for attitudes which have changed over the five year period values are not significantly different five years apart this study provides additional evidence that use of the contingent valuation method can provide useful information for environmental policy analysis

willingness to pay for energy saving measures in residential buildings this paper uses a choice experiment to evaluate the consumers willingness to pay for energy saving measures in switzerland s residential buildings these measures include air renewal ventilation systems and insulation of windows and facades two groups of respondents consisting respectively of 163 apartment tenants and 142 house owners were asked to choose between their housing status quo and each one of the several hypothetical situations with different attributes and prices the estimation method is based on a fixed effects logit model the results suggest that the benefits of the energy saving attributes are significantly valued by the consumers these benefits include both individual energy savings and environmental benefits as well as comfort benefits namely thermal comfort air quality and noise protection

improving the economics of building energy code change a review of the inputs and assumptions of economic models abstract building energy code change in australia and many other developed nations is subject to standardised economic tests with a net present value calculation at the heart of the economic analysis although many nations have introduced minimum energy efficiency standards for residential and commercial buildings increases in stringency have been hindered by limitations to the range of private and societal impacts typically incorporated in regulatory impact assessments given the policy move towards net zero energy homes a more comprehensive set of inputs and robust assumptions are needed to support further regulatory change yet the literature provides substantial evidence of many private and societal costs and benefits not commonly incorporated into the economic assessments that underpin regulatory change drawing on a case study of australian and uk residential regulatory change assessments this paper highlights limitations to the range of inputs and assumptions currently incorporated within the economic arguments applied during residential energy code change processes and presents a more comprehensive economic argument that could support further stringency improvements

further results on willingness to pay for nonmarket goods abstract some implications of substitution relationships between private and public goods for measuring the value of changes in nonmarket goods such as environmental quality are explored if a market good is hicks neutral to quality for some price vector the total value of discrete changes in quality consisting of both use and nonuse value can be measured from empirical demand coefficients a plausible motivation for neutrality is developed in the contexts of specifying incomplete demand systems for weak complements to quality and measuring nonuse value when the consumption of weak complements is held at zero previous results on bounding marginal willingness to pay for nonmarket goods are also strengthened

a producer s willingness to pay for information under price uncertainty theory and application the central focus of this paper is the development of an easily computable money metric of an agent s willingness to pay for information under risk empirical estimates of the value of information are important for obtaining insights into issues such as the informational efficiency of alternative market structures the effects of the quality of agent s conditional forecasts of market prices on the efficiency of resource use and the social profitability of information supplied by private enterprise and public agencies the paper draws on previous contributions to the theory of competitive firm under price uncertainty namely rothschild and stiglitz 8 sandmo 9 and more recently pope 5 6 and pope chavas and just 7 the latter contribution provides insight into the econometric application of the theory and into the validity of producer surplus measures of firm welfare under risk in these models the production decision is made given the producer s subjective distribution of output price the value of information in this context can be formulated using the bayesian approach which amounts to a comparison of expected utility levels from choices based on prior information with choices based on additional information contributions in this area are numerous and include those of lindley 4 winkler 10 and more recently gould 2 and hess 3 who focused on the effects of risk preferences and the nature of the distribution of random events on the value of information however the literature has given little attention to the question of deriving a money metric of an agent s willingness to pay for information under risk that can be applied to an econometric analysis of observed behavior in part the problem lies with the empirical application of bayes theorem to explain the observed behavior of risk averse agents while estimates of the agent s prior distribution of uncertain events may be obtained from observed choices or in some cases elicited directly the content of additional information the process by which additional information becomes available and whether the agent behaves

willingness to pay for quality improvements comparative statics and interpretation of contingent valuation results this paper extends variation function theory by examining the effects of changes in prices quality and income on willingness to pay for quality change comparative static effects are found for both on site users and nonusers of the resource these results are used to interpret contingent valuation empirical models for example the substitution and complementary relationships between trips to natural resource sites can be identified this paper also suggests tests for comparison of contingent valuation with recreation demand models and other tests of validity

a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

heat savings and heat generation technologies modelling of residential investment behaviour with local health costs abstract the trade off between investing in energy savings and investing in individual heating technologies with high investment and low variable costs in single family houses is modelled for a number of building and consumer categories in denmark for each group the private economic cost of providing heating comfort is minimised the private solution may deviate from the socio economical optimal solution and we suggest changes to policy to incentivise the individuals to make choices more in line with the socio economic optimal mix of energy savings and technologies the households can combine their primary heating source with secondary heating e g a woodstove this choice results in increased indoor air pollution with fine particles causing health effects we integrate health cost due to use of woodstoves into household optimisation of heating expenditures the results show that due to a combination of low costs of primary fuel and low environmental performance of woodstoves today included health costs lead to decreased use of secondary heating overall the interdependence of heat generation technology and heat saving choice is significant the total optimal level of heat savings for private consumers decrease by 66 when all have the option to shift to the technology with lowest variable costs

improving willingness to pay estimates for quality improvements through joint estimation with quality perceptions willingness to pay for quality change may depend on heterogeneous perceived quality levels contingent valuation studies should include measures of quality perceptions as covariates in the willingness to pay model in order to avoid omitted variable bias variation in quality perceptions across respondents leads to a potential endogeneity of quality perceptions i address the potential for endogeneity bias using an instrumental variables approach in which a measure of quality perceptions is included as a determinant of willingness to pay and is simultaneously determined by various exogenous factors the willingness to pay model is estimated jointly with quality perceptions allowing for correlation of the error terms using data on willingness to pay for water quality improvements in the neuse river in north carolina i reject exogeneity of perceived quality correcting for endogeneity improves the measurement of willingness to pay by differentiating willingness to pay among respondents with heterogeneous quality perceptions

integration of multiple national markets for electricity the case of norway and sweden during the second part of the 1990s the nordic denmark finland norway and sweden countries have created a unique multinational market for electricity this paper aims to analyse the degree of integration of the different national markets that constitute the nordic electricity market in particular the norwegian and swedish wholesale and retail electricity markets are analysed the results suggest that the wholesale markets are well integrated thus prices differ significantly only during periods with unusually high or low supply of hydropower however the retail markets are not integrated to the same degree thus retail prices and trade margins differ significantly differences in the national electricity market legislation seem to be a key factor behind these differences

replacement or additional purchase the impact of energy efficient appliances on household electricity saving under public pressures abstract this study examined the influence of additional and replacement purchases of energy efficient air conditioners on power savings we used a questionnaire survey and measured electricity use data from 339 japanese households collected from two city areas with different level of government requested electricity saving rates namely osaka 10 and matsuyama 5 the main findings of our study are as follows 1 households that purchased energy efficient air conditioners saved more electricity than those that did not 2 additional purchase households showed significant energy savings whereas replacement households did not the rebound effect may negate the energy saving effects of a new air conditioner 3 altruistic attitude is associated with more active participation in power saving 4 households in osaka saved more electricity than those in matsuyama probably because the government call to save electricity was more forceful

valuing smart meters abstract this paper assesses to what extent consumers are willing to make use of the features and capabilities offered by smart meters via a choice experiment households are offered the choice between a set of smart meters described by six attributes impact on the comfort and privacy level functionality visibility cost savings and investment outlay we estimate a main effects conditional logit model and a main effects random parameter logit model including interactions with socio demographic characteristics the results show that households have heterogeneous preferences for some attributes but not for others the estimates are used to assess marginal willingness to pay values from a policy perspective our findings suggest that sufficient effort should be devoted to designing the smart metering devices and to informing households without careful preparation a mandatory or voluntary roll out of smart meters risks to be unsuccessful because device characteristics do not meet consumer needs

a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression abstract this paper challenges the w m hanemann amer j agr econom 66 332 341 1984 and c sellar j p chavas and j r stoll j environ econom management 13 382 390 1986 utilizations of logit models to estimate the value of non market resources from referendum survey data these data are more informative than conventional choice data the random utility interpretation of logit models is therefore too restrictive bypassing the utility function entirely it will be shown that parameters and standard errors for utility theoretic inverse hicksian demand functions can be extracted directly and much more simply estimated demand functions need not be limited to those corresponding to the linear in parameters utility difference specifications which can be handled by packaged logit programs

another theorem on using market demands to determine willingness to pay for non traded goods abstract this paper contains a proof of the following theorem let e1 and e1 denote an agent s expenditures on two groups of goods which are substitutes and complements to a non traded good suppose that both the agent s income and the quantity of the non traded good provided him have a positive effect on these two amounts then these effects can be used to place upper and lower bounds on the agent s marginal willingness to pay for the non traded good

a new unified approach to evaluate economic acceptance towards main green technologies using the meta analysis the aim of this paper is to analyze the main determinants of the economic acceptability of four green technologies gts alternative fuel vehicles energy savings in residential buildings smart meters and renewable electricity using a meta analysis on a sample of 35 selected papers which provided 245 primary data this approach allows detecting relationships across heterogeneous studies avoiding the subjectivity of qualitative surveys we implement a new two step procedure first we compute a measure of the implicit price for a kilogram of co2 avoided pco2 homogenizing the usable information for the gts considered second we conduct a meta regression using the computed pco2 values to estimate the socio economic determinants impact in general our results show a wide degree of acceptability for gts which is stronger among european citizens in particular it emerges that on average the estimated pco2 is positive for the gts considered and additional positive effects exist when respondents are confronted with an explicit reference to quantitative targets in terms of co2 abatement a clear proposal for payment timing and a specific renewable electricity mix these results indicate that information and transparency are crucial to spur gts deployment therefore to support gts market penetration public and private institutional stakeholders have to provide ad hoc information to the end users setting a clear and suitable system of prices to increase the economic value end users place on gts

zero energy homes are they economically viable whilst net zero energy homes are espoused in many policy circles and many bespoke examples have been constructed to demonstrate their technical feasibility there is a scarcity of evidence demonstrating such a standard would be economically rational particularly for large scale housing development where orientation and aspect may not always be optimal drawing on energy monitoring evidence and construction economics associated with a nearly zero energy housing estate in adelaide australia this paper explores the economic feasibility of the net zero energy home policy in warm temperate climates the results demonstrate that using economic tools and assumptions typically applied for building energy regulatory policy changes net societal economic benefits significantly outweigh costs the clear economic outcomes combined with expected health and productivity benefits from improved levels of thermal comfort should provide security to policy makers to progress home energy standards towards net zero energy performance

specification tests for mixed demand systems with an emphasis on combining contingent valuation and revealed data abstract in a world characterized by r unrationed goods i e market goods and n r rationed goods such as most environmental goods necessary and sufficient conditions for the existence of an underlying rational preference structure are derived based on a system of mixed demand functions with complete information with incomplete information the case of a partial demand system is addressed and a test for separability is proposed the implications for testing rationality in a world characterized by combined rp and sp individual data are examined for data consistency testable conditions are derived

the effects of additive outliers on tests for unit roots and cointegration this article discusses the properties of the univariate dickey fuller test and the johansen test for the cointegrating rank when there exist additive outlying observations in the time series we provide analytical as well as numerical evidence that additive outliers may produce spurious stationary hence the dickey fuller test will reject a unit root too frequently and the johansen test will indicate too many cointegrating vectors the results easily generalize to models with temporary change outliers through an empirical example we discuss how additive and temporary change outliers can be detected in practice and we show how dummy variables can be used to remove the influence of such extreme observations

testing between competing models of sharecropping the marshallian approach assumes a prohibitively high cost of monitoring the sharecropper s activities while the monitoring approach argues that landlords stipulate and effectively monitor sharecroppers activities i present new evidence using detailed data collected from eight indian villages most tenants own some land of their own this provides a controlled environment in studying the impact of contractual arrangements the differences in input and output intensities on owned minus sharecropped land of the same household are found to be sizable and significant suggesting a rejection of the monitoring approach and supporting the notion of the marshallian productive inefficiency of sharecropping

poverty reduction through land transfers the world bank s titling reforms and the making of subsistence agriculture abstract the world bank emphasizes land reform as a key pro poor intervention expecting the transfer of land to the rural poor to trigger a straight transition from poverty and subsistence to entrepreneurial and commercial smallholder farming this article asks how and why world bank prescriptions change in response to developments on the ground that contradict initial expectations to show that the transition to commercialization is hardly a straight one as it involves contradictory elements it builds on an analysis of close to twenty years of world bank reports on land reform in four post communist countries to show how and why the transfer of land and commercialization end up contradicting rather than mutually supporting each other the analysis shows that as a result of this contradiction wb inspired policies prioritize commercialization over poverty reduction and their underlying understanding of poverty has changed from poverty as lack of farmland to poverty as lack of alternatives to farming for the world bank the problem in these countries is not so much the failure of having pro poor results but the decreasing control over smallholders perceived to have responded to insufficient reforms by withdrawing from markets into subsistence yet the analysis further suggests that even though presently seen as a sign of underdevelopment the subsistence capacity of local populations following land transfers was in earlier reports encouraged as it was believed to have the effect of supporting the commercialization of the sector and relieving welfare systems this aspect of reforms is now relatively rarely mentioned and subsistence is assumed to be an effect of anything but reforms cast instead as a sign of insufficient market creation

identifying electricity saving potential in rural china empirical evidence from a household survey in recent years there has been a fast growing body of literature examining energy saving potential in relation to electricity however empirical studies focusing on non western nations are limited to fill this gap this study intends to examine the electricity saving potential of rural households in china using a unique data set from the china residential electricity consumption survey crecs in collaboration with the china general social survey cgss conducted nationwide at the household level in rural china we use a stochastic frontier model which allows us to decompose residential electricity consumption into the minimum necessary amount of consumption based on physical characteristics e g house size house age number of televisions or refrigerators and estimate the consumption slack i e the amount of electricity consumption that could be saved which depends on various factors we find that rural households in china are generally efficient in electricity saving and the saving potential is affected by fast information feedback and social demographic characteristics instead of by the averaged electricity price or energy efficiency labelling signals in addition we find no evidence of regional heterogeneity on electricity saving potential for rural households policy implications are derived

exogeneity tests of market boundaries applied to petroleum products us antitrust law makes market definition and the calculation of marketshare statistics an integral part of the determination of the anticompetitive impact of a merger because markets frequently overlap however market definition is rarely an easy task a statistical test that can be used as an aid in defining markets is proposed here time series techniques are used to test if price in one region is exogenous to the process that determines price in another the rejection of exogeneity can be an indication that the two regions are economically linked and thus may belong to a common geographic market the test is applied to petroleumproduct prices from various regions of the united states time series techniques have long been appreciated by macroeconomists the uses to which they have been put range from testing for the exogeneity of variables used in the construction of macroeconomic models sims 1972 for example to discovering empirical regularities in macroeconomic data without imposing a priori structure on the observations ashenfelter and card 1982 for example in contrast these techniques have not been so

geographic markets causality and railroad deregulation this paper presents an approach to defining a market using the notion of instantaneous causality the market for which the approach is empirically implemented is the flour market in the united states over the period january 1979 through october 1982 one anomaly over this period was the deregulation of railroad rates in october 1980 the empirical results based on three spatially diffuse cities suggest that the market is national in scope and that after railroad deregulation the price interrelationship between cities was strengthened

making negotiated land reform work initial experience from colombia brazil and south africa abstract the paper describes background initial experience and future challenges associated with a new negotiated approach to land reform this approach has emerged as following the end of the cold war and broad macroeconomic adjustment many countries face a second generation of reforms to address deep rooted structural problems and provide the basis for sustainable poverty reduction and economic growth it reviews possible theoretical links through credit market or political channels between asset ownership and economic performance program characteristics in each country as well as lessons for implementation and implications for monitoring and impact assessment are discussed

toward a food secure future ensuring food security for sustainable human development in sub saharan africa food security remains a top development priority and global concern it is enshrined in the 2030 agenda for sustainable development in sustainable development goal two food security is also a core component of the human development and capability paradigm since food access and entitlements are critical for reinforcing essential human capabilities in introducing this special issue this paper argues that agriculture is central to improving food security and reducing poverty in africa it suggests that realizing the potential of agriculture in africa requires rapid increases in land productivity and increases in agricultural yields a science based approach that integrates gender and sustainability is critical to meet this goal through the design and implementation of policies that improve the availability farm inputs and farm technology the paper concludes by introducing the papers in this special issue

testing for cointegration power versus frequency of observation further monte carlo results abstract this paper studies the effects of increasing the frequency of observation and the data span on the johansen cointegration tests the ability of the tests to detect cointegration depends more on the total sample length than the number of observations

energy efficiency investments in the context of split incentives among french households the residential sector offers considerable potential for reducing energy use and greenhouse gas ghg emissions particularly through energy efficient renovations the objective of this study is twofold first i aim to provide initial empirical evidence of the extent to which split incentives between landlords and tenants may lead to underinvestment second i investigate the influence of tax credits and energy burdens on energy efficiency expenditures given the complexity of studying the decision to invest in energy saving renovations i use a bivariate tobit model to compare decisions about energy efficient works and repair works even when the renovation expenditures seem quite similar the analysis shows that tenants are doubly penalized they have high energy expenditures due to energy inefficient building characteristics and because they are poorer than homeowners they are unable to invest in energy saving systems the results also confirm that tax credits are ineffective in the split incentives context in terms of public policy the government should focus on low income tenants and mandatory measures such as minimum standards seem appropriate financial support from a third party financer also might be a solution

models for referendum data the structure of discrete choice models for contingent valuation abstract in 1979 bishop and heberlein introduced an appealing variant of the contingent valuation method which required only yes or no responses hanemann developed a utility theoretic interpretation of the yes no responses which has helped popularize the approach recently cameron has offered another interpretation also utility theoretic which she argues is more general than the hanemann random utility model this paper compares the deterministic models suggested by hanemann and cameron showing them to be dual to each other it shows that correct specification of either function must exclude endogenous variables such as quantity demanded it also demonstrates that using utility theoretic models allows one to compare travel cost models and contigent valuation models on the basis of their implied behavior not on the unobservable surplus or variation measure

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

determinants and policy implications for household electricity saving behaviour evidence from beijing china this research sets out to explore the possibilities for further saving in household electricity consumption through a study of the residents willingness and behavioural characteristics in electricity saving as applied within a chinese context based on an extensive literature review the authors argue that economic benefits policy and social norms and past experience may have a positive correlation with household electricity saving behaviour while the discomfort caused by electricity saving activities may exert a negative effect on it through a sample of 816 randomly selected residents in beijing the propositions are examined using logit regression analysis the conclusions support the ideas concerning both the positive influence of economic benefits policy and social norms and past experience as they affect broader electricity saving behaviour and the negative influence of the discomfort caused by electricity saving activities finally some inferences are drawn and suggestions are offered for policy makers and further studies

using a choice experiment to estimate the benefits of a reduction of externalities in urban areas with special focus on electrosmog traffic noise air pollution and electromagnetic pollution i e nonionizing radiation also called electrosmog are typical negative local externalities in urban areas they are side effects of human and economic activities e g road transport telecommunication and they affect individuals well being negatively without compensation in recent years the increased number of mobile phone antennas in residential areas and thus the increased intensity of radiated power has aroused public concern discussions and protests the view of an antenna is annoying an increasing number of inhabitants in this article the stated choice experiment ce is used to estimate the willingness to pay wtp residents in the cities of zurich and lugano place on the reduction of these three environmental loads estimation results reveal that there is a positive and significant wtp for a reduction of air pollution and traffic noise levels to those limit values fixed by the government respondents also show wtp for reducing

split incentive effects on the adoption of technical and behavioral energy saving measures in the household sector in western europe abstract significant differences in the adoption of energy saving measures between homeowners and renters were found in the survey data of 1 248 households from the netherlands germany and belgium in this study we examined the influence of split incentive effects between homeowners and renters which stem from differences between those who pay and those who enjoy the benefits of the adoption of energy efficient ee technology and energy saving behaviors average marginal effects were used to measure the magnitude of the split incentive effect by considering many ee technologies and energy saving behaviors both split incentive effects were measured and compared for the first time producing some interesting results there is clear evidence of split incentive problems for both measures and on average homeowners were found to be16 08 more likely than renters to have access to adoptable ee technologies while the effects were much smaller only 4 28 for adopting behavioral measures the results were highly robust for household characteristics and specific psychological determinants such as willingness to pay and environmental beliefs policy implications are provided to address the split incentive problems in rental markets in household sectors based on our results

household willingness to pay for green electricity in urban and peri urban tigray northern ethiopia determinants and welfare effects abstract this paper set out to estimate household willingness to pay for green electric services and welfare gains attributed to such schemes for this purpose contingent valuation survey was conducted on 300 urban and peri urban households in northern ethiopia a bivariate probit model was used to elicit willingness to pay and analyze determinants of household willingness to pay on the other hand welfare gains were analyzed using consumer and producer surpluses the mean willingness to pay was estimated to be birr 12 5 0 66 usd per month per household for five years on top of monthly electricity bill among others income played positive role on willingness to pay while difference in willingness to pay behavior was observed between male and female headed households in addition distance to wood and charcoal alternative energy markets played encouraging role for willingness to pay results from the welfare analysis show that there is significant societal gain to be made both in terms of surplus for households and producers government if the previously untapped green electricity service was implemented the revenue producer surplus for the state would be instrumental in contributing to the state s endeavor to generate a much needed capital for investment in and expansion of renewable energy

marginal costs and co benefits of energy efficiency investments the case of the swiss residential sector abstract key elements of present investment decision making regarding energy efficiency of new buildings and the refurbishment of existing buildings are the marginal costs of energy efficiency measures and incomplete knowledge of investors and architects about pricing co benefits and new technologies this paper reports on a recently completed empirical study for the swiss residential sector it empirically quantifies the marginal costs of energy efficiency investments i e additional insulation improved window systems ventilation and heating systems and architectural concepts for the private sector first results on the economic valuation of co benefits such as improved comfort of living improved indoor air quality better protection against external noise etc may amount to the same order of magnitude as the energy related benefits are given the cost benefit analysis includes newly developed technologies that show large variations in prices due to pioneer market pricing add on of learning costs and risk components of the installers based on new empirical data on the present cost situation and past techno economic progress the potential of future cost reduction was estimated applying the experience curve concept the paper shows for the first time co benefits and cost dynamics of energy efficiency investments of which decision makers in the real estate sector politics and administrations are scarcely aware

modern value chains and the organization of agrarian production empirical studies of agrarian production in developing countries often find that small farms possess a productivity advantage over larger farms eswaran and kotwal 1986 famously derive this inverse farm size productivity relationship from the structure of agrarian production the focal prediction of their model is that in otherwise equivalent economies a more egalitarian land distribution raises both output and producer welfare the traditional spot procurement system implicit in the eswaran and kotwal model however diverges fundamentally from modern contractual procurement practices we therefore develop a new model of agrarian production in order to determine whether the introduction of a modern value chain alters the welfare effects of land redistribution the inverse farm size productivity relationship persists in our model but we find that more egalitarian land distribution leads to nonmonotonic changes in producer welfare we also find that the introduction of a modern sector can harm the laboring classes

consumer choice on ecologically efficient water heaters marketing strategy and policy implications in japan abstract this study examines how consumers select ecologically efficient water heaters in japan energy conservation in household water heating is increasingly important for reducing an amount of co 2 emission because the share of water heating in household energy consumption is approximately 30 recently japanese households have widely used ecologically efficient electric heat pump water heaters eco cute or gas fired water heaters eco jozu the total number of such efficient water heaters sold in japan was more than 2 5 million at the end of 2008 this study investigates various factors and impacts of marketing strategy for promoting the appliances in japan we apply mixed and nested logit models to a disaggregated choice data on water heaters from 2004 to 2008 this study considers retail energy prices a government financial support and marketing activities as important factors for appliance selection in addition we consider consumers housing attributes such as floor space and age of building this empirical study finds two business implications one of the two implications is that an increase in an energy price may enhance a choice probability of eco cute and eco jozu because a price increase invites consumer s consciousness on energy conservation so that a cost reduction on energy consumption becomes essential in a use of the efficient appliances the other implication is that marketing activities especially by recommendations from sales representatives and or housing suppliers are important for consumer behaviors the other important findings are discussed in this study this business experience in japan is useful to the other countries where ecologically efficient water heaters are not popular at the current moment

returns to capital in microenterprises evidence from a field experiment small and informal firms account for a large share of employment in developing countries the rapid expansion of microfinance services is based on the belief that these firms have productive investment opportunities and can enjoy high returns to capital if given the opportunity however measuring the return to capital is complicated by unobserved factors such as entrepreneurial ability and demand shocks which are likely to be correlated with capital stock the authors use a randomized experiment to overcome this problem and to measure the return to capital for the average microenterprise in their sample regardless of whether they apply for credit they accomplish this by providing cash and equipment grants to small firms in sri lanka and measuring the increase in profits arising from this exogenous positive shock to capital stock after controlling for possible spillover effects the authors find the average real return to capital to be 5 7 percent a month substantially higher than the market interest rate they then examine the heterogeneity of treatment effects to explore whether missing credit markets or missing insurance markets are the most likely cause of the high returns returns are found to vary with entrepreneurial ability and with measures of other sources of cash within the household but not to vary with risk aversion or uncertainty

estimating substitution and expansion effects using a profit function framework this study reports a first attempt to derive all the relevant information with respect to the structure of production of an industry using knowledge of only a profit function using estimates of a profit function for canadian agriculture a procedure to separate substitution and expansion effects for both inputs and outputs was implemented information concerning net input and output substitution and complementarity possibilities were obtained the most important empirical results suggest that the hypothesis of nonjoint production of crop and animal outputs in canadian agriculture cannot be rejected and that hired and operator labor are complements rather than substitutes

effects of cheap talk on consumer willingness to pay for golden rice a large body of literature suggests willingness to pay is overstated in hypothetical valuation questions as compared to when actual payment is required recently cheap talk has been proposed to eliminate the potential bias in hypothetical valuation questions cheap talk refers to process of explaining hypothetical bias to individuals prior to asking a valuation question this study explores the effect of cheap talk in a mass mail survey using a conventional value elicitation technique results indicate that cheap talk was effective at reducing willingness to pay for most survey participants however consistent with previous research cheap talk did not reduce willingness to pay for knowledgeable consumers

an experimental approach to climate finance the impact of auction design and policy uncertainty on renewable energy equity costs in europe abstract this paper aims at shedding some lights on how policy induced uncertainty affects the cost of capital of renewable energy power plants to this end the paper focuses on renewable energy auctions and on the ongoing brexit negotiations first the paper reviews auction frameworks across europe and discusses the impact of the different designs on project risk then a stated preference approach is leveraged to investigate how policy design and the uncertainty regarding the future arrangements between the uk and the eu contribute to determine the cost of equity for renewable energy the results show that improved auction design can help to lower the equity cost between 0 5 and 1 5 the evidence on brexit is rather weak and if anything suggests only a higher relevance of these negotiations for english based investors than for those based in eu27

stated versus revealed knowledge determinants of offsetting co2 emissions from fuel consumption in vehicle use abstract this paper examines the role of prior knowledge in offsetting co2 emissions from fuel consumption in vehicle use the main result of our econometric analysis on the basis of unique representative data from drivers license holders in the usa and germany refers to the strong discrepancy between the stated and revealed knowledge of co2 offsetting the revealed knowledge measured by the correct estimation of the costs for this offsetting practice has a positive impact on the stated purchase of corresponding offsetting credits in both countries in contrast the effect of the stated knowledge of offsetting is not robust and in some cases even negative surprisingly it cannot even be confirmed that drivers license holders who claim that they are more than sufficiently informed estimate these costs more accurately

willingness to pay for quality improvements should revealed and stated preference data be combined abstract in this article we propose theoretically consistent welfare measurement of use and nonuse values for an improvement in environmental quality with revealed and stated preference data an analytical model based on the comparative static analysis of the variation function that describes the relationship between recreation demand and dichotomous choice contingent valuation models is estimated our results show that revealed and stated data should not be combined under the same assumed preference structure unless the two decisions imply the same change in behavior induced by the quality change in addition our results indicate scope effects in willingness to pay measures estimated with stated preference data

the influence of rebate programs on the demand for water heaters the case of new south wales this paper examines the role of australian hot water system rebate programs in shifting the existing stock of electric water heaters toward more climate friendly versions using two unique data sets from new south wales homeowners the first data set is based on a survey of households who recently purchased a water heater before and after the rebate programs were in place the other is based on a set of stated preference questions asked of households soon to face a replacement decision while the former allows us to look at recent responses the latter enables us to forecast future demand we find that the programs significantly increase shares of solar heat pump systems the programs however appear less effective in reducing the stock of electric heaters for households with access to natural gas this pattern is consistent in both datasets results from the discrete choice experiments suggest considerable heterogeneity with respect to household preferences toward different types of water heaters and the discount rates they hold the effective cost of reducing carbon emissions via incentives for water heater replacement is considered from the counterfactual perspective of no government incentives

combining contingent valuation and travel cost data for the valuation of non market goods the travel cost method tcm has long been used to infer the economic value of nonmarket resources and public goods more recently contingent valuation cvm survey methods have gained popularity for eliciting these values here cvm survey responses are combined with tcm data on actual market behavior to estimate jointly both the parameters of the underlying utility function and its corresponding ordinary demand function this is a prototypical empirical example of a new modeling strategy variants of which should prove useful in many applications especially where reliance on a single valuation method is undesirable

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

market definition in antitrust analysis a regression based approach alleged violations of either sherman 2 s antimonopoly strictures or clayton 7 s proscriptions against anticompetitive mergers necessarily involve a particular product and must occur in a particular place that is the plaintiff in either a 2 or 7 suit must define a relevant market within which the violation alleged has occurred even in the most mundane antitrust analysis however market definition is rarely readily accomplished and unaccompanied by a series of caveats and the possibility of the opposing parties in an antitrust suit failing to contest each other s proffered definition is virtually nil 2 because economists from

economic versus belief based models shedding light on the adoption of novel green technologies abstract understanding the determinants for the adoption of novel green consumer technologies is important to effectively foster their diffusion energy and environmental science literature often takes an approach based on economic variables such as objectively measureable household and technology characteristics increasingly also subjective variables based on personal belief are considered on the basis of a survey about the intention to adopt an exemplary novel green consumer technology intelligent thermostats we contribute to the clarification of the explanatory power of these two approaches we first compare the economic model to the belief based model and second investigate how beliefs about the green technology are influenced by personal environmental norms and innovativeness our evaluation shows that the belief based model explains considerably higher variance in the intention to adopt thereby the perceived hedonic satisfaction usefulness habit and facilitating conditions reveal as key determinants moreover environmental norms show lower impact than personal innovativeness in the discussion we consolidate these findings and point to the risk of omitted variable bias when selectively including belief based variables in adoption models our findings suggest that policies can effectively accelerate the early market diffusion of green consumer technologies by incentivizing retailers to introduce and market such technologies

part whole bias in contingent valuation will scope effects be detected with inexpensive survey methods the purpose of this paper is to test for scope effects with the contingent valuation method we use data from a telephone survey focusing on water quality improvements in the albemarle and pamlico sounds in north carolina we find that the willingness to pay estimates are sensitive to the scope of the policy these results suggest that the use of inexpensive survey methods may not be the cause of the failure to detect scope effects in some recent contingent valuation studies

inequality as a determinant of malnutrition and unemployment policy this paper explores the policy implications that are obtained once it is recognized that at low nutrition intakes a person s productivity is an increasing function of intake in the context of a fully general equilibrium model it is shown that if aggregate assets in an economy are neither large nor small certain patterns of lorenz improving asset redistributions or nutrition transfers increase aggregate output and reduce the volume of involuntary unemployment and the incidence of undernourishment copyright 1987 by royal economic society

efficient estimation methods for closed ended contingent valuation surveys closed ended contingent valuation surveys can be very useful in the evaluation of nonmarket resources respondents merely state whether they would accept or reject a hypothetical threshold amount either as payment for giving up access to the resource or as a fee for its use the authors develop a maximum likelihood procedure which exploits the variation in the threshold values to allow direct and separate point estimates of regression like slope coefficients and error standard deviations without truncation bias their illustration uses data from a survey of recreational fisherman to examine factors which influence individuals willingness to pay copyright 1987 by mit press

poverty and land redistribution abstract despite a theoretical literature that promises that land transfers will have large impacts on the well being of poor households well identified empirical evidence on the efficacy of land redistribution is scarce in an effort to fill this gap this paper examines south africa s land redistribution for agricultural development lrad program we exploit features of lrad program implementation to extract exogenous variation in whether and for how long applicant households enjoyed land transfers binary treatment estimates which compare treated with untreated households show that beneficiary households on average experienced a 25 increase in per capita consumption our preferred continuous treatment estimates which analyze only the subset of treated households identify the impact time path of land transfers on consumption these estimates show that living standards initially drop and then after 3 4 years rise to 150 of their pre transfer level these results are statistically significant and robust to a statistically more conservative identification strategy

heterogeneous impact dynamics of a rural business development program in nicaragua abstract we study the impacts of a rural development program designed to boost the income of the small farm sector in nicaragua exploiting the random assignment of treatment we find statistically and economically significant impacts on gross farm income and investment in productive farm capital using continuous treatment estimation techniques we examine the evolution of program impacts over time and find that the estimated income increase persists and that the impacts on productive capital stock continue to rise even after the program concluded additionally panel quantile methods reveal striking heterogeneity of program impacts on both income and investment we show that this heterogeneity is not random and that there appear to exist low performing household types who benefit little from the program whereas high performing upper quantile households benefit more substantially analysis using generalized random forests a machine learning algorithm points toward greater program impacts for households who were disadvantaged at baseline even after controlling for this source of heterogeneity we find large and persistent differences in how much different types of households benefited from the program while the benefit cost ratio of the program is on average positive the impact heterogeneity suggests that business development programs aiming to engage farm households as agricultural entrepreneurs have limitations as instruments to eliminate rural poverty

factors influencing commercial buildings to obtain green certificates abstractidentifying the key factors that influence commercial buildings decision to obtain voluntary green certificates is essential to building sustainability enhancement using commercial buildings in the state of new york multinomial logit and nested logit models demonstrate that there is a significant correlation between the characteristics of commercial buildings such as square footage lot size and years built and green certification more interestingly if a commercial building is occupied by its owner likelihood of green certification is actually smaller this finding not only confirms that ongoing energy savings are heavily discounted when deciding whether to incur the upfront cost of green certification but also suggests that the rental premium enjoyed by green buildings is likely greater in terms of present value than the expected operating cost savings another explanation could be that investor owners must operate in a competitive market for tenants while owner occupiers do not operate

construct validity of dichotomous and polychotomous choice contingent valuation questions in this note we conduct construct validity tests for dichotomous choice dc and polychotomous choice pc contingent valuation questions contrary to previous results we find that dc and pc estimates of willingness to pay are theoretically valid convergent valid and similar in terms of statistical precision similar to previous results pc respondents are less sensitive to information than dc respondents we conclude that dc and pc valuation questions are construct valid for this study sequential pc valuation questions could be used in studies where obtaining information about the certainty or intensity of respondent preferences would be useful
