escaping the polluter pays trap financing wastewater treatment on the tijuana san diego border abstract building and operating infrastructure to address transboundary environmental hazards requires dividing the cost of pollution prevention between bordering states when cost burden questions arise the solution often suggested is the polluter pays principle ppp however when political and economic relations between neighboring countries are asymmetrical other cost burden principles are often adopted given the discrepancy between theory and practice the aim of this study is to identify some of the available cost burden principles and to examine when they might replace the ppp the pollution prevention regime along the san diego tijuana border is used as a case study it was found that under asymmetrical relations there are several competing cost burden principles some principles are adopted since they are perceived by some to be fair while others are adopted since they provide effective wastewater treatment the ones that were found effective are those that offset to some degree existing asymmetries this explains why the ppp was replaced in the san diego tijuana case with other cost burden principles that better offset the asymmetries and thus they provided a more effective wastewater treatment than the ppp

a two sector endogenous growth model with habit formation abstract in this paper we study an endogenous growth model with physical and human capital in which consumption habits enter the utility function multiplicatively we show that although the utility function with multiplicative habits is nonconcave and unbounded an interior optimal growth path still exists it is uniquely determined and it converges to a balanced growth path we also find that habit formation in consumption lowers the convergence speed of the optimal path toward the balanced growth path

arbitrary values good causes and premature verdicts abstract this paper offers an alternative interpretation of the conclusions kahneman and knetsch propose based on two contingent valuation cvm surveys the evaluation argues that while framing is important to cvm estimates the design implementation and empirical findings reported from these surveys do not support their judgments moreover with the exception of temporal embedding conventional economic descriptions of individual behavior can explain the response patterns that they suggest are at variance with standard value theory

an ecological economic assessment of deregulation of international commerce under gatt this paper discusses the ecological economic implications of deregulation of trade as promoted by the general agreement on tariffs and trade gatt 1 this includes both environmental2 and socio economic factors such as standards of living and equity we outline fifteen overlapping problems with deregulation or free trade we argue that many environmental problems cannot be resolved equitably efficiently or sustainably by unregulated markets and that there is no alternative to public intervention in certain situations we repeat the 1987 brundtland commission s question of how far into international trade should regulation penetrate wced 1987 the commission s call for gatt s environmental reform 3 has not yet been heeded

local identification and valuation of ecosystem goods and services from opuntia scrublands of ayacucho peru abstract opuntia scrublands are important ecological economic systems in the andean area they perform a major role protecting slopes against erosion improving the soil properties and providing a variety of products employed in the human diet and in animal feeding as well as cochineal insects a highly valued source of dyes the collection of the insects has represented an important economic activity for the local communities since pre columbian times current peruvian production represents between 85 and 90 of the global market and is mainly based on collection of the insect in natural opuntia scrublands located in the poorest andean areas of ayacucho although much is known about the financial benefits of cochineal for exporters and dye manufacturers information about the value of standing opuntia scrubs to collectors and the relative contribution of opuntia scrubs to their household economies is scarce here we contribute to the estimation of the use value of opuntia scrublands to local communities in ayacucho by initially exploring the cultural domain of opuntia in order to identify the ecosystem goods and services recognized by peasants and later presenting empirical estimates of their importance to annual household income

the relevance of attitudinal factors for the acceptance of energy policy measures a micro econometric analysis abstract this paper empirically examines the individual support of the german energy transition in total and especially of six single energy policy measures which are components of the energy transition our micro econometric analysis with binary and ordered probit models on the basis of data from a broad survey of citizens reveals the important role of several attitudinal factors with respect to our indicators for perceived personal costs of the energy transition the estimation results point to a weak evidence for economic self interest due to some negative correlations between expected energy price increases due to the energy transition and the support of single energy policy measures interestingly however the concern that the energy transition alone causes strong energy price increases is not shared by the majority of the respondents the estimation results also suggest that the support of several energy policy measures is strongly correlated with environmental values however the most important attitudinal factor is obviously political identification the econometric analysis suggests that an overall left green policy identification is positively correlated with the support of the energy transition in total and an identification with ecological policy is positively correlated with the acceptance of several single energy policy measures the econometric analysis especially supports the more sophisticated categorization of political orientation since for example a liberal conservative policy orientation is not significantly correlated with the support of the energy transition in total

market based systems for reducing chemical use in agriculture in the united states this study uses a computable general equilibrium cge model of the u s economy to estimate the economic effects of agricultural fertilizer and pesticide input reductions on individual farm sectors and on the economy as a whole the costs of reducing agricultural chemicals using a market based approach and a command and control approach are compared the real cost to society of restrictng fertilizer and pesticide use by 20 percent across all uses is estimated to be 2 3 billion a market based approach that would provide incentives to reduce chemical use in the most cost efficient manner would be about 10 percent less costly

exact and superlative welfare change indicators an exact welfare change indicator is defined to be a known function of the price and quantity data for two periods for a utility maximizing consumer which is exactly equal to the hicksian equivalent variation a welfare change indicator is termed superlative if it is exactly equal to the equivalent variation for an expenditure function which has a second order approximation property the paper exhibits a number of superlative welfare change indicators and also reviews the earlier attempts of hicks and weitzman to obtain equivalent variation measures that had a second order approximation property

economic growth with intergenerational altruism in this paper we study the properties of equilibria in an aggregative growth model with intergenerational altruism in this model each generation is active for a single period at the beginning of this period it receives an endowment of a single homogeneous good which is the output from a bequest investment made by the previous generation it divides the endowment between consumption and investment the return from this investment constitutes the endowment of the next generation each generation derives utility from its own consumption and that of its immediate successor however since altruism is limited in the sense that no generation cares about later successors the interests of distinct agents come into conflict models of this type have been used to analyze a number of issues concerning intergenerational altruism one line of research pursued by arrow 1973 and dasgupta 1974a elucidates the implications of rawls principle of just savings others beginning with phelps and pollak 1968 have addressed the question of how an altruistic growth economy might actually evolve over time topics of subsequent investigation have included the efficiency and optimality of equilibrium programs and the implications of intergenerational altruism for the distribution of wealth unfortunately the positive features of equilibrium programs have received little attention from previous authors aside from a few comments by kohlberg 1976 virtually nothing is known about the asymptotic behaviour of capital stocks in these models in particular will the long run capital stock which arises from intergenerational conflict be higher or lower than the turnpike associated with the solution to the optimal planning problem on a priori grounds the answer is not clear agents who take only a limited interest in the future will tend to bequeath less than those who are far sighted however since each generation views its children s bequest as pure waste it must bequeath a larger sum to obtain the same consumption value in this paper we obtain steady state results for equilibrium capital stocks completely analogous to the well known optimal planning results by comparing steady states we

principles for the provision of public goods from agriculture modeling moorland conservation in scotland this paper is concerned with policies for the supply of public environmental goods from the farm sector in particular we characterize the buying of these goods by the public from farmers using the provider gets principle this principle is well established in oecd countries as we demonstrate results from ecological economic modeling of the conservation of heather moorland in northern scotland using this principle are described this model enables us to identify spatially differentiated ecological targets and to calculate the minimum necessary payments needed to achieve these targets

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

the effects of environmental policy towards agriculture on trade some considerations abstract a growing awareness of environmental problems associated with agricultural production has led to the consideration and in many cases the introduction of more stringent environmental controls across industrialized countries in theory countries that introduce costly environmental regulations should experience a reduction in their international trade competitiveness in polluting commodities in contrast countries that fail to undertake an environmental protection programme presumably increase their export market share in the production of items that damage the environment this viewpoint investigates these potential agricultural trade effects and suggests that they are likely to be quite modest

environmental costing for agriculture will it be standard fare in the farm bill of 2000 this paper starts by discussing and estimating the environmental costs of agricultural production the author uses a separate benefit transfer intended to expose methodological issues to construct each cost category of agricultures s external effects this is followed by a simple description of the framework for production decisions that account for environmental costs included are attribution of environmental externalities and measurement of environmental costs finally the author discusses research implications of environmental costing including tqm and environmental policy analyses environmental services and their unit values strategies for measuring environmental values and prognosis for agricultural adders 42 refs 1 fig 1 tab

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

intertemporal complementarity and optimality a study of a two dimensional dynamical system the theory of optimal intertemporal allocation has been developed primarily for the case in which the objective function of the planner or representative agent can be written as u c1 c2 ldots equiv sum infty t 1 delta t 1 w c t where c t represents consumption at date t w the period felicity function and delta epsilon o 1 a discount factor representing the time preference of the agent

international equity and differentiation in global warming policy ne of the major obstacles to reaching a comprehensive agreement on global warming is the setting of greenhouse gas emission reduction targets for individual countries long standing tensions between industrialized and developing countries have raised the issue of equity in burden sharing moreover individual industrialized nations have pleaded special circumstances and have sought differentiation in their obligations this paper analyzes alternative rules for distributing tradable carbon dioxide emissions permits a non linear programming model which distinguishes between allocation based and outcome based rules is used to analyze the relative welfare outcomes the model is applied to the world body of nations and yields several important policy implications

saving among young households evidence from japan and italy the tendency of both young and old households to save or dissave a very small fraction of their total resources is inconsistent with a strict life cycle model we concentrate on young households and document their behavior drawing on italian and japanese data the theoretical structure we propose is broadly consistent with the spirit of the life cycle theory while at the same time capable of accounting for the observed facts without relying on assumptions about credit markets or the degree of consumer foresight

one sector nonclassical optimal growth optimaility conditions and comparative dynamics the authors consider a one sector nonclassical model of optimal economic growth characterized by a convex concave production function they provide in a dynamic programming context a characterization of all local interior maximum of the miximand of the bellman equation these conditions are the euler equation and a second order condition namely that the marginal propensity to consume is less than one an example is used to illustrate these conditions also several comparative dynamic results are derived in particular it is shown that the maximum and minimum selections out of the optimal consumption correspondence shift down as the discount factor increases copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

competitive equilibrium cycles recently there has been a surge of interest in endogenous business cycles that arise in competitive laissez faire economies in the context of standard overlapping generations economies conditions for the existence of equilibrium cycles have been given by grandmont 1983 and by benhabib and day 1982 models of the economy with extrinsic uncertainty or sunspots that have been developed by shell 1977 and by cass and shell 1983 see also balasko 1983 can also lead to equilibrium cycles

efficiency equity tradeoffs in targeting payments for ecosystem services this article develops an analytic framework to analyze the tradeoff between economic efficiency and distributional equity in targeting payments for ecosystem services pes it also proposes an empirical procedure to trace out the efficiency equity frontier where the program is pareto optimal in the sense that it cannot be improved upon to achieve either higher efficiency or distributional equity without compromising the other we apply the procedure to the conservation reserve program crp the largest pes program in u s history to analyze a whether it is possible to improve both the efficiency and the distributional equity of the program and b what the choice made by crp administrators implies about the political economic balance results reveal that a crp administrators forfeited about 9 of efficiency for an 18 23 improvement in distributional equity depending on the equity indicator used in the eighteenth signup of the crp b reducing the maximum allowable rental rate for all contracts would improve efficiency at the cost of distributional equity c reducing the maximum county enrollment cap would reduce efficiency without generating much improvement in distributional equity and d the crp targeting criterion could be redesigned to achieve both higher efficiency and higher distributional equity

on self interested preferences for burden sharing rules an econometric analysis for the costs of energy policy measures abstract this paper examines the acceptance of burden sharing rules that refer to the costs of the german energy transition which is one of the most challenging and disputed national climate and energy policy measures based on data from a comprehensive survey of more than 2200 citizens the empirical analysis reveals that the polluter pays rule has by far the highest support compared with the ability to pay rule and especially compared with the equal pay rule which is widely refused in the sample since the distribution of the costs of the german energy transition is largely in line with a polluter pays rule its strong support seems to contribute to the high acceptance of the energy transition at all the main result of our econometric analysis with multivariate binary and ordered probit models is that not only some attitudinal factors like environmental values and political identification but especially economic self interest is relevant since equivalent energy expenditures have a significantly negative effect on the support of the polluter pays rule and especially equivalent income has a significantly negative effect on the preference for the ability to pay rule these results suggest that the use of distributional arguments for the criticism of energy policy measures is not necessarily value driven on the basis of real perceptions of distributive justice but can also be strategically motivated to prevent and combat economically unfavorable measures together with the strong general support of the polluter pays rule these results suggest that a sharp reorientation of the german energy transition due to distributional arguments is not very useful

the lack of strategic sustainability orientation in german water companies abstract water supply and distribution companies wsc are dealing with one of the most crucial natural resources that is why the german national sustainability strategy highlights water as one of the priority fields of action in germany wsc show characteristics of natural monopoly the distinct separation between public institutions and the private sector as well as municipal operators being responsible for practicing special functions is characteristic for the german water economy from an evolutionary perspective it is of interest how german wsc implement sustainability strategically therefore strategic concepts and tools facing sustainability e g iso 14001 reporting and balanced scorecard etc were analysed and evaluated in the context of the water industry using literature studies and web analysis the relevant data of 110 german wsc was put together a cross sectional design was used in order to find patterns possible gaps are highlighted and ongoing steps to foster sustainability are stressed this study points out a sustainable management is just marginally implemented the results obviously show that there are differences between large companies and smes facing sustainability requirements wsc having own regenerative power generation and an integrative thinking of farming and water supply are part of good practice

the measurement of preferences over the distribution of benefits the importance of the reference point this paper uses the atkinson method which was initially developed to measure the shape of the social welfare function swf in the domain of income to measure the shape of the swf with respect to the distribution of health benefits two separate studies were conducted involving a total of 71 respondents a comparison of the results across the two studies suggests that reference point effects play an important role in determining responses thus more research is needed on the role that reference point effects ought to and do play in determining the nature and extent of the efficiency equity trade off before the results of studies of this kind can be interpreted as equity parameters which may simply be plugged into an appropriately specified swf

population and the environment a parable of firewood and other tales the author analyzes the relationship between population and the environment with a focus on the role which environmental degradation and natural resources depletion may play in producing the population pressure which lies behind such degradation and depletion especially in developing countries the principal conclusion of this analysis is that the possibilities for a stable equilibrium between human population and its environment are quite limited i show that parental altruism toward their children can only make matters worse if socially unchecked by leading to an increase of the birthrate in every environmental state in comparison with that which would occur in its absence excerpt

the values jury to aid natural resource decisions congressional legislation emphasizes that public resource allocation should reflect the values citizens assign to those resources yet information about assigned values and preferences of members of the public including economic measures of value required by decision makers is often incomplete or unavailable existing sources of information about the public s values for use in resource allocation decisions and damage assessment include existing markets public surveys including contingent valuation and public involvement each of these sources has serious limitations

the measurement of individual utility and social welfare it has been suggested by a number of economists that decisions about how to allocate scarce health care resources should be informed by the cost per quality adjusted life years qalys of the different alternatives one of the criticisms of the qaly approach is that it is based on the measurement of individual utility yet the values elicited are used to inform social choice in this respect it is argued that the qaly approach fails to take account of distributional issues that are known to be important in the context of health care this paper addresses this issue and presents an approach grounded in microeconomic theory that is flexible enough to deal with a wide range of efficiency equity trade offs while making the nature of the trade off transparent in addition it is an approach that is relatively simple to investigate empirically and the results of a preliminary study are presented as illustration of this

a joint framework for analysis of agri environmental payment programs this article presents an approach for simultaneously estimating farmers decisions to accept incentive payments in return for adopting a bundle of environmentally benign best management practices using the results of a multinomial probit analysis of surveys of over 1 000 farmers facing five adoption decisions in a voluntary program we show how the farmers perceptions of the desirability of various bundles change with the offer amounts and with which practices are offered in the bundle we also demonstrate an estimator for the mean minimum willingness to accept for the adoption of a practice conditional on the cost share offers for other practices agri environmental payment programs play an important part in improving the environmental performance of agriculture claassen and horan batie lynch and smith smith feather and cooper claassen et al federallevel interest in developing these programs is currently strong for example the 2002 farm act calls for a five fold increase in funding for the usda s environmental quality incentives program eqip this article focuses on voluntary programs designed along the lines of the eqip which provides incentive payments to encourage producers to adopt environmentally benign land management practices such as nutrient management manure management and integrated pest management for policy making purposes it would be useful to know the sensitivity of the producer s decision to enroll in response to a schedule of potential incentive payments and to which practices are bundled together such information can be used to assess the costs of encouraging farmers to try various environmentally benign management practices commonly known as best management practices or bmps eqip offers the farmer a suite of bmps to choose from existing published research cooper and keim modeled the probability of farmer adoption of bmps as a function of the incentive payment with each practice be

reconsidering agri environmental policy permitted by the uruguay round agreement agri environmental policies are increasingly being used to redress the balance between jointly produced agricultural and environmental outputs and are permitted by the uruguay round ur agreement with the general provision that they not distort trade in this paper we argue that any market consequences of efficient welfare enhancing agri environmental policies should not be considered trade distorting to consider them so is inconsistent with economic efficiency and with ecological integrity social cost benefit analysis cba is a more appropriate test and guide of trade consistency for agri environmental policies and using trade effects as the test may not enhance social welfare moreover specific provisions in the ur agreement restricting payments under agri environmental policies to opportunity costs are not warranted on economic efficiency grounds and consign the environment to a status subsidiary to agricultural output

uncertain lifetime consumption and dissaving in retirement this paper asks whether the continued accumulation or mild dissaving observed among the retired can be explained by uncertain lifetime in the absence of annuities after an initial period influenced by borrowing constraints under constant relative risk aversion uncertain lifetime depresses consumption by a proportion increasing with age if the elasticity of intertemporal substitution in consumption is small illustrative computations based on actual income and survival data show that plausible elasticities are sufficiently small to give this effect the reduction in consumption is large enough to explain much of the lack of decumulation by the elderly

the equity efficiency trade off in environmental policy evidence from stated preferences the design of environmental policy raises several equity issues in particular the distribution of benefits and costs at the same time it has often been argued that there is a trade off in environmental policy between equity and efficiency which brings these issues firmly to the attention of environmental economics in this paper we use a simple choice experiment to elicit individual preferences over equity efficiency trade offs in the context of two environmental problems local air pollution and global climate change we find that equity matters to people as much as efficiency does in the design and delivery of environmental policy

interactions between agricultural and environmental policies a conceptual framework agricultural policy has a well documented impact on farmers production decisions and those decisions land water and agricultural chemical use may in turn affect the environment there is a public perception that existing agricultural policies are linked to agricultural pollution as exemplified by the conclusions of the recent national research council report alternative agriculture 1989 there is only limited theoretical or empirical research addressing these linkages however this paper develops a conceptual framework that can be used to analyze the interactions between agricultural and environmental policies and pollution this framework integrates physical and economic models at a disaggregate level necessary to capture the heterogeneity of the physical environment and the economic behavior of farmers following e hochman and d zilberman 1978 the disaggregate units can be statistically aggregated to a level useful for policy analysis agricultural and environmental policies can be categorized according to their effects on the intensive and extensive margins combining the different policy instruments with the microeconomic heterogeneity we find that existing agricultural and environmental policies can have either positive or negative effects of nonpoint source pollution to infer an aggregate effect requires data that do not currently exist our framework provides a basis for empirical investigations of these effects given adequate data moreover we find that agricultural policy instruments can be used to mitigate pollution if used appropriately

consumption over the life cycle and over the business cycle the main aim of this paper is to assess the validity of the life cycle model of consumption in particular we address an issue that has recently received much attention especially in the macroeconomic literature that of excess sensitivity of consumption growth to income growth we do this using a time series of cross sections and a novel and flexible parameterization of preferences the former allows us to address aggregation issues directly while with the latter we can allow both the discount factor and the elasticity of intertemporal substitution eis to be affected by various observable variables and lifetime wealth the main findings can be summarized as follows i the excess sensitivity of consumption growth to labor income disappears when we control for demographic variables this is true both at life cycle and business cycle frequencies ii estimation of a flexible specification of preferences indicates that the elasticity of intertemporal substitution is a function of several variables including the level of consumption the eis increases with the level of consumption as expected iii the variables that change the eis are also important in explaining why we observe excess sensitivity over the business cycle iv we are able to reconcile our results with those reported both in the macro and micro literature v in our specification the elasticity of intertemporal substitution is not very well determined this result however should be taken with care as we have not made an effort to construct a preferred specification which would probably include additional controls for labor supply behavior the evidence presented shows that the life cycle model cannot be easily dismissed indeed we believe that the model does a good job at representing consumption behavior both over the life cycle and over the business cycle
