option value empirical evidence from a case study of recreation and water quality a procedure for measuring option value and other preservation values of water quality is developed and applied to a case study area in the south platte river basin colorado benefits from water based recreation activities are the focus of the study the results provide an empirical test and confirmation of weisbrod s proposal that option value and other preservation values represent important social benefits and should be added to the aggregate consumer surplus of recreation activities to determine the total benefit of environmental amenities to society in the absence of such an estimate insufficient resources would be allocated by society to preservation of unique environments such as pristine mountain streams where mineral and energy development may irreversibly degrade water quality

will business cycles in the euro area converge a critical survey of empirical research this survey of business cycle synchronization in the european monetary union focuses on two issues have business cycles become more similar and which factors drive business cycle synchronization we conclude that business cycles in the euro area have gone through periods of both convergence and divergence still there is quite some evidence that during the 1990s business cycle synchronization in the euro area has increased higher trade intensity is found to lead to more synchronization but the point estimates vary widely the evidence for other factors affecting business cycle synchronization is very mixed

the real effects of financial integration abstract this paper shows how correlations in gdp fluctuations rise with financial integration finance serves to increase international correlations in both consumption and gdp fluctuations which explains the persistent gap between the two in the data a quantity puzzle the positive association between financial integration and gdp correlation constitutes a puzzle as theory suggests a negative relation if anything nevertheless it prevails in the data even after the effects of finance on trade and specialization are accounted for

valuing option existence and bequest demands for wilderness to assess the relative importance of current costs and future benefits of nuclear waste storage we develop a simple model of bequest value the basic model of nonparternalistic altruism is extended to account for the uncertain nature of the externality

the short term impact of a domestic cap and trade climate policy on local agriculture a policy simulation with producer behavior this study is intended to develop understanding of possible impact of a domestic cap and trade climate policy on local agriculture we focus the study on the transition period after the policy has raised input prices for production but before establishment of new equilibrium in agricultural commodity markets we construct a policy simulation model based on production economics that explicitly considers producer behavior in the focal period we apply the model to a production region in the us to quantify the impact of different levels of carbon price on production cost production value and farm income our case study shows that 1 producers have ability to alleviate the cost impact 2 producers may benefit by selling carbon credits in the carbon market but the revenue is likely to be limited 3 the economic return of farm production is critical to the impact assessment 4 the impact may vary across producers and 5 regulation on the fertilizer industry is an important policy element that can influence the assessment of the impact this study has important implications for climate policy design

trade finance specialization and synchronization i investigate the determinants of business cycle synchronization across regions the linkages between trade in goods financial openness specialization and business cycle synchronization are evaluated in the context of a system of simultaneous equations the main results are as follows i specialization patterns have a sizable effect on business cycles most of this effect is independent of trade or financial policy but directly reflects differences in gdp per capita ii a variety of measures of financial integration suggest that economic regions with strong financial links are significantly more synchronized even though they also tend to be more specialized iii the estimated role of trade is closer to that implied by existing models once intra industry trade is held constant the results obtain in a variety of data sets measurement strategies and specifications they relate to a recent strand of international business cycle models with incomplete markets and transport costs and on the empir

a test of the equality of closed ended and open ended contingent valuations a test is developed to find whether open ended and closed ended contingent valuation mechanisms lead to significantly different results the test is based on joint estimation of willingness to pay responses to open and closed ended questions asked of the same sample of individuals in a public good example individuals do respond differently depending on question format possible explanations include different incentives for strategic behavior and respondents lack of familiarity with the open ended question type no differences in willingness to pay were found in a private good example

ecological economic analysis of wetlands scientific integration for management and policy abstract wetlands all over the world have been lost or are threatened in spite of various international agreements and national policies this is caused by 1 the public nature of many wetlands products and services 2 user externalities imposed on other stakeholders and 3 policy intervention failures that are due to a lack of consistency among government policies in different areas economics environment nature protection physical planning etc all three causes are related to information failures which in turn can be linked to the complexity and invisibility of spatial relationships among groundwater surface water and wetland vegetation integrated wetland research combining social and natural sciences can help in part to solve the information failure to achieve the required consistency across various government policies an integrated wetland research framework suggests that a combination of economic valuation integrated modelling stakeholder analysis and multi criteria evaluation can provide complementary insights into sustainable and welfare optimising wetland management and policy subsequently each of the various components of such integrated wetland research is reviewed and related to wetland management policy

more than total economic value how to combine economic valuation of biodiversity with ecological resilience abstract the assessment of total economic value has become a pragmatic and popular approach in nature valuation yet criticisms have been raised one major point of critique is that total economic value bases the monetary value of ecosystems purely on the flow of human benefits of services of ecosystems and consequently ignores questions of sustainable use of natural capital per se this paper explains why total economic value by itself is in principle an inadequate concept to guide sustainable use of ecosystems and gives an overview of essential ecological theory that needs to be taken into account in addition to total economic value to fully include ecosystem sustainability the paper concludes with a framework for combining ecological theory with economic valuation the key elements here are theoretical ecological insights about ecosystem resilience and portfolio theory which offers an economic perspective on investment in biodiversity portfolio theory puts total economic value in a framework where investment in biodiversity is expanded to cover functional diversity and mobile link species in order to maintain ecosystem resilience and so fosters sustainable use of ecosystems

intra industry trade and business cycles in asean a new resolve for both increased economic integration and monetary and exchange rate cooperation has started to emerge in the association of southeast asian nations asean especially since the 1997 1998 asian financial crisis according to the optimum currency area theory the degree of trade integration is one of the most important criteria for joining a currency union the large increase in intra asean trade in recent years raises the question of whether the asean countries are becoming better prepared to form a currency union this article sets to test whether the recorded increase in intra asean trade is leading the asean members to closer economic integration and thus to better satisfy the criteria for a common currency two separate models are estimated for that purpose first a variation of the model of frankel and rose 1997 was estimated for the asean members next a new panel data methodology was conducted the results with our own model were very significant and robust when four of the ase

valuing environmental commodities some recent experiments a general model of consumer behavior is proposed to assess six recent experiments that have attempted to reveal preferences for environmental goals each experiment used a mix of both the techniques and the theory of demand for non market commodities and each was designed to estimate a non market attitude associated with the environment and to analyze potential biases in the techniques the six cases show some consistency in results the linkage within the contingent market between the environmental attribute institutional setting and the bidding instrument must be realistic and accepted by the respondent to avoid biased results possibly the most important result is the replication of results using a traditional property value study and a contingent bidding approach all evidence obtained to date suggests that hedonic studies of property values or wages travel costs and survey techniques all yield values well one order of magnitude in accuracy 41 references 2 tables

exploring futures for amazonia s sierra del divisor an environmental valuation triadics approach to analyzing ecological economic decision choices in the context of major shifts in boundary conditions abstract this text presents a new methodological approach to ecological economic analysis employing georgescu roegen s flow fund theory of economic process it offers an alternative to monetary valuation based analyses and aims to contribute toward advancing work concerned with addressing complex ecological economic questions as complete wholes the methodology is demonstrated through reference to the empirical case of a proposed rail link between peru and brazil which would cut across the sierra del divisor of western amazonia connecting the pacific and atlantic coasts and further opening up the amazon commodity frontier in order to analyze the potential impacts of the rail link four flow fund representations of economic process two at the regional and two at the local level are developed in order to juxtapose two alternative political economy contexts that might govern the rail link s impacts in the region one where conservation is prioritized over cash income and one where it is not our results suggest that completion of the rail link under the current political economy context which prioritizes cash income over conservation is likely to have substantial negative consequences for forest conservation in both peru and brazil and for local livelihoods throughout the region

substitution effects in the valuation of multiple environmental programs abstract a theoretical framework for understanding substitution and complementary effects between environmental programs is derived a multiple program valuation function is specified and its structure analyzed a maximum likelihood estimator is derived to estimate the parameters of the valuation function using referendum type contingent valuation data the empirical analysis shows that the conventional benefit aggregation approach of independent valuation and summation overstates the benefits of two and three program policies by an average of 24 and 54 respectively

valuation by conflict abstract nonmarket valuation remains a central issue in ecological and environmental economics this paper examines the properties of an ex post revealed preference approach to value nonmarket goods valuation through observed effort expended in an environmental conflict we consider the strategic interaction between players in a conflict address the implied nash equilibrium and report a benchmark 4x rule as an ex post valuation estimate for a symmetric player conflict we then illustrate the degree of bias that exists once one allows for asymmetries in delegation ability and valuation the benchmark tends to overestimate value if a firm hires a powerful delegate who receives a large contingency fee

the new approach to wilderness preservation through benefit cost analysis over the last 15 years economists of resources for the future led by john krutilla have been developing a new approach to wilderness preservation this paper offers a concise exposition of their approach and adds a few new steps the basic ingredient of the new approach is a perception of declining net benefits of wilderness development and rising net benefits of wilderness preservation over time these alter the entire shape of the benefit cost analysis of potential development the new steps involve reversibility postponability and recognition of multiple interest rates

currency unions and international integration this paper characterizes the integration patterns of international currency unions such as the cfa franc zone we empirically explore different features of currency unions and compare them to countries with sovereign monies by examining the criteria for mundellos concept of an optimum currency area we find that members of currency unions are more integrated than countries with their own currencies for instance we find that currency union members have more trade and less volatile real exchange rates than countries with their own monies business cycles are more highly synchronized across currency union countries than across countries with sovereign monies

influence of soil conservation on farm land values worldwide concern for the loss of agricultural soil has led many governments to establish programs to slow the loss of soil from farms mcconnell 1983 has shown however that in the absence of externalities farmer decisions on investment to reduce onfarm soil loss can be socially optimal and concludes p 188 as follows increasing soil loss does not imply that farmers ignore physical production relations if farmers know that the soil base affects farm resale value they will conserve it it suggests that the impact of soil depth on the value of farms be investigated earlier rausser 1980 reached a similar conclusion suggesting that land values which fail to reflect soil quality encourage the farmer to ignore his long run impact on the resource two recent studies failed to find clear cut relationships between soil erosion and farm land prices ervin and mill 1985 942 in a cross section study of farm land prices in page county iowa concluded the group of variables measuring past and future erosion damages and conservation structures did not exhibit large and reliable effects gardner and barrows 1985 studied the capitalization of the value of soil conservation practices into farm land prices in southwestern wisconsin and concluded p 946 the most reasonable conclusion is the most obvious conservation

one money one market the effect of common currencies on trade currency unions their dramatic effect on international trade a gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade the panel data bilateral observations for five years during 1970 90 covering 186 countries includes 300 observations in which both countries use the same currency i find a large positive effect of a currency union on international trade and a small negative effect of exchange rate volatility even after controlling for a host of features including the endogenous nature of the exchange rate regime these effects statistically significant imply that two countries sharing the same currency trade three times as much as they would with different currencies currency unions like the european emu may thus lead to a large increase in international trade with all that that entails andrew rose

environmental issues and economic decisions in developing countries abstract this paper explains the key role of environmental economics in incorporating environmental concerns into decision making and in facilitating the more efficient management of natural resources as a step toward sustainable development it reviews concepts and techniques for valuation of environmental impacts for use in conventional cost benefits analysis as well as key related aspects including environmental impacts of economywide policies multicriteria analysis risk and uncertainty and discount rate issues several developing country case studies are summarized which cover a range of practical valuation methods the evidence presented suggests that the valuation techniques for determining use values may be applied successfully in appropriate cases but examples involving nonuse values are rare the use of multiobjective desicion methods also needs to be explored where economic valuation is not feasible

threshold effects and incentives for the conservation of biodiversity biological diversity is a central component of the stock of natural capital on which all economic development is based other things being equal loss of biologically diversity implies loss of development potential and its conservation through sustainable use or outright protection implies the protection of that potential one characteristics of biodiversity loss of especial importance is that biodiversity loss more than any other current environmental problem is associated with ecological threshold effects the paper explores the implication of this characteristics for the properties of a biodiversity conservation strategy

economic valuation of biodiversity sense or nonsense this paper critically evaluates the notion and application of economic monetary valuation of biological diversity or biodiversity for this purpose four levels of diversity are considered genes species ecosystems and functions different perspectives on biodiversity value can be characterized through a number of factors instrumental vs intrinsic values local vs global diversity life diversity vs biological resources etc a classification of biodiversity values is offered based on a system of logical relationships among biodiversity ecosystems species and human welfare suggestions are made about which economic valuation methods can address which type of biodiversity value the resulting framework is the starting point for a survey and evaluation of empirical studies at each of the four levels of diversity the contingent valuation method is by far the most used method an important reason is that the other valuation methods are unable to identify and measure passive or nonuse values of biodiversity at first sight the resulting monetary value estimates seem to give unequivocal support to the belief that biodiversity has a significant positive social value nevertheless most studies lack a uniform clear perspective on biodiversity as a distinct concept from biological resources in fact the empirical literature fails to apply economic valuation to the entire range of biodiversity benefits therefore available economic valuation estimates should generally be regarded as providing a very incomplete perspective on and at best lower bounds to the unknown value of biodiversity changes 2001 elsevier science b v all rights reserved

the economic benefits of surface water quality improvements in developing countries a case study of davao philippines two nonmarket valuation techniques the contingent valuation method and travel cost model are used to estimate the economic value that people in davao philippines place on improving the water quality of the rivers and sea near their community the contingent valuation and travel cost estimates are very close to each other and are quite low both in absolute terms and as a percentage of household income these findings suggest that water pollution control is simply not a high priority for davao s residents and support the argument that households willingness to pay for environmental amenities such as improved water quality is low

economic valuation of the leuser national park on sumatra indonesia abstract the leuser ecosystem in northern sumatra is officially protected by its status as an indonesian national park nevertheless it remains under severe threat of deforestation rainforest destruction has already caused a decline in ecological functions and services besides it is affecting numerous economic activities in and around the leuser national park the objectives of this study are twofold firstly to determine the total economic value tev of the leuser ecosystem through a systems dynamic model and secondly to evaluate the economic consequences of deforestation versus conservation disaggregating the economic value for the main stakeholders and regions involved using a dynamic simulation model economic valuation is applied to evaluate the tev of the leuser national park over the period 2000 2030 three scenarios are considered conservation deforestation and selective use the results are presented in terms of 1 the type of benefits 2 the allocation of these benefits among stakeholders and 3 the regional distribution of benefits the economic benefits considered include water supply fisheries flood and drought prevention agriculture and plantations hydro electricity tourism biodiversity carbon sequestration fire prevention non timber forest products and timber the stakeholders include local community members the local government the logging and plantation industry the national government and the international community the regions considered cover the 11 districts involved in the management of the leuser ecosystem with a 4 discount rate the accumulated tev for the ecosystem over the 30 year period is us 7 0 billion under the deforestation scenario us 9 5 billion under the conservation scenario and us 9 1 billion under the selective utilisation scenario the main contributors in the conservation and selective use scenarios are water supply flood prevention tourism and agriculture timber revenues play an important role in the deforestation scenario compared to deforestation conservation of the leuser ecosystem benefits all categories of stakeholders except for the elite logging and plantation industry

differentiating use and nonuse values for coastal pond water quality improvements this paper measures the benefits of water quality improvements in three coastal ponds on the island of martha s vineyard massachusetts u s a use option and existence values were elicited from martha s vineyard property owners by the contingent valuation method on average more than half of the total benefits are attributed to existence value results from the heckman selection model show that the exclusion of protest as well as missing bids does not cause significant bias in estimating respondents willingness to pay socioeconomic characteristics are found to have distinctively different influences on use option and existence values different model parameters are likely to be estimated depending on which value categories are measured by a selected valuation technique these findings emphasize the importance of nonuse values from water quality improvements and of socioeconomic characteristics for measuring different categories of values

global business cycles convergence or decoupling we analyze the evolution of the degree of global cyclical interdependence over the period 1960 2008 using a dynamic factor model we decompose macroeconomic fluctuations in output consumption and investment into a global factor factors specific to country groups and country specific factors we find that during 1985 2008 there is some convergence of business cycle fluctuations among industrial economies and among emerging market economies surprisingly there is a concomitant decline in the relative importance of the global factor we conclude that there is evidence of business cycle convergence within each of these two groups of countries but divergence or decoupling between them

the myth of decoupling the decoupling hypothesis is the idea that business cycles in emerging market economies have become more independent from business cycles in advanced economies in recent years decoupling essentially amounts to a structural break in the degree of business cycle interdependence between the two groups of economies and it can be tested as such we develop an innovative measure of business cycle interdependence based on the euclidean distance available at the annual frequency which allows for a proper test for a structural break in a graphical setup we also make use of a standard econometric test both approaches point to the same conclusion there has been no decoupling in recent years if anything the degree of business cycle interdependence has become stronger

the decoupling of emerging economies theoretical and empirical puzzle with the growing importance of the emerging economies ees in the international scene a lively debate has begun on whether the national economic cycles are converging or the cycles of ees and advanced economies aes are becoming disconnected the so called hypothesis of decoupling of ees from the aes given the important practical implications that decoupling could have for example on the definition of national and international economic policies and on business strategies aimed at investment diversification and risk management the question kindles not only the interest of academics but also policymakers and practitioners are very interested in the issue the decoupling question has been long debated in different circles and from different points of view this survey aims to retrace the steps of this debate and to provide some suggestions for future empirical researches

construct validity of averting cost measures of environmental benefits construct validity is concerned with the consistency of empirical measures with theoretical relationships this paper reviews and extends the theoretical relationship between averting costs and willingness to pay measures of these two theoretical constructs with empirical averting costs savings and contingent valuation from one population are used to establish construct validity of the averting cost technique used empirical results indicate that the contingent valuation and averting costs measures have a low correlation although low correlation is consistent with the construct validity of averting costs measures these results indicate that inferences from averting cost measures are quite limited

valuing biodiversity for use in pharmaceutical research biodiversity prospecting has been touted as a mechanism for both discovering new pharmaceutical products and saving endangered ecosystems it is unclear what values may arise from such activities however evidence from transactions is incomplete and existing theoretical models are flawed we calculate an upper bound on the value of the marginal species even under favorable assumptions this bound is modest slightly modified assumptions lead to drastically lower estimates we extend our findings to the value of the marginal hectare of habitat and find that the incentives for habitat conservation generated by private pharmaceutical research are also at best very modest

monetary valuation in life cycle assessment a review abstract monetary valuation is the practice of converting measures of social and biophysical impacts into monetary units and is used to determine the economic value of non market goods i e goods for which no market exists it is applied in cost benefit analysis to enable the cross comparison between different impacts and or with other economic costs and benefits for this reason monetary valuation has a great potential to be applied also in life cycle assessment lca especially in the weighting phase however several challenges limit its diffusion in the field which resulted in only a few applications so far the authors have performed a review of different monetary valuation methods for use in lca firstly monetary valuation approaches methods and lca applications were identified secondly key features and the strengths and weaknesses of each monetary valuation method were determined finally monetary valuation methods and lca applications were evaluated according to a comprehensive set of criteria ranging from scientific foundation to uncertainty and complexity it was found that observed and revealed preference methods and the abatement cost method have limited applicability in lca whereas the choice experiment method and the budget constraint method are the best options for monetary valuation in lca

the value of biodiversity markets society and ecosystems the value of biodiversity is discussed at different levels including market value non market values to humans and the value of biodi versity to ecosystems the main conclusion is that although market exchange values of environmental services may be used to justify biodiversity protec tion measures it must be stressed that exchange value constitutes a small portion of total biodiver sity value the total value of existing biodiversity is largely unknown but indications are that it is essen tial to human existence the various levels of biodi versity value point to the need for a hierarchical and pluralistic methodology to determine appropri ate policies for its preservation jel q21 i introduction among ecologists there is a general con sensus that biodiversity1 is of critical impor tance to the health of ecosystems and even for the long term survival of the human species there is also a consensus that bio diversity is being lost at a rate which is a cause for concern 2 economists on the other hand generally view biodiversity as just an other good which is to be placed in the basket of market choices just as any other the discussion of the specifics of biodiver sity policy has been unsatisfactory partly because of the different meanings of the word value used by economists and ecolo gists many ecologists fail to understand the logic of market allocation and why biologi cal resources are used in seemingly irra tional ways many economists fail to ap preciate the narrowness of the concept of economic value as indicated by relative prices determined by market exchange fol lowing anderson 1966 and brown 1984 the discussion below considers economic measures of value to be species of the genus assigned value which belongs to the family value many biologists and paleontologists be lieve that we are at a critical point in the history of the human species and perhaps even in the 600 million year history of com plex multicelled life on earth if the paleon tologists and biologists who study the phe nomenon of mass extinction are correct the current human induced mass extinction may be of the same order of magnitude as the five other major extinction episodes which destroyed between 20 and 96 percent of existing species on the planet ehrlich and ehrlich 1992 ward 1994 wilson 1992 we are living in a truly remarkable period in earth s 41 billion year history the valua tion decisions our species has made in the recent past and will make during the next few decades will determine the fate of life on earth for the next tens of millions of years it is critical to clarify the language and concepts we use to estimate the value of biodiversity and thus policies leading to its destruction or preservation the importance attached to the issue of biodiversity preservation necessarily in volves ethical judgments about duty to fu ture generations and responsibility toward the nonhuman natural world although in dividuals hold a variety of conflicting beliefs about human responsibility to the natural world this does not mean that policy choices

capturing the complexity of biodiversity a critical review of economic valuation studies of biological diversity biodiversity is a highly complex and abstract ecological concept even though it is not one physical entity it influences human well being in multiple ways mostly indirectly while considerable research effort has been spent on the economic valuation of biodiversity it remains to be a particularly challenging valuation object valuation practitioners therefore have to use proxies for biodiversity many of which are very simple single species habitats this paper presents a comprehensive and critical review of biodiversity valuation studies with special emphasis on biodiversity valuation in order to depict the state of the art in this research field it develops evaluation criteria so as to identify best practice applications and shows that the field of biodiversity valuation studies is rather heterogeneous regarding both valuation objects and valuation methods on the basis of our evaluation criteria and best practice studies we suggest that to account for the complexity and abstractness of biodiversity multi attribute approaches with encompassing information provision should be used that emphasise the roles biodiversity plays for human well being

business cycle synchronization in the emu this article asks whether the business cycles of the eu countries have become more or less synchronized after the introduction of the euro our findings show that all countries in our eu sample are better synchronized with the emu wide economy in the post emu period than they were before the euro we also show that this increase in synchronization is present in all components of aggregate demand as well as two supply side variables but it is more pronounced in the trade components imports and particularly exports it is also shown that the increase in trade within the emu area is at least partly responsible for the increase in cyclical synchronization

traditional vs modern production systems price and nonmarket considerations of cacao producers in northern ecuador many factors besides profit maximization such as nonmarket ecological and social benefits influence smallholder households to adopt a specific agricultural production system or sell in a particular market thus different analytical techniques are needed that take into consideration more than monetary income to fully capture these additional benefits to better understand the production decisions of smallholder farmers we build on previous work on the household model and shadow wage estimation to develop a shadow wage for ecuadorian cacao producers that includes these nonmarket benefits we found that the shadow wage correctly indicated that on average these households would prefer to use an agroforestry production system instead of the more profitable modern system because of the nonmarket benefits received from the former system

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

the effect of technical progress on erosion damage and economic incentives for soil conservation tion service scs was established by congress in response to the alarm generated by the high erosion rates observed during the dust bowl days through technical assistance provided by scs and through cost share payments made by the agricultural conservation and stabilization service farmers have been encouraged to adopt conservation practices designed to reduce soil loss from agricultural lands but after more than 40 years of effort soil loss rates remain excessive on 97 million acres usda 1980 6 the long term productive potential of these lands is being impaired by excessive erosion in this paper a damage function which incorporates the long run cost of erosion to a farmer is presented and applied to evaluate conservation tillage in the palouse wheatland of the pacific northwest the role of technology in the conservation adoption decision is explored to see if policy implications for the control of erosion in the region can be drawn from the analysis as erosion proceeds its cumulative effect is evident in reduced crop yield of the numerous factors that affect crop yields many are related to erosion damage soil moisture organic matter content fertility and soil structure are examples the depth of topsoil remaining is used as a proxy in this analysis for various variables related to erosion which impact crop yields although cumulative soil erosion may diminish the future productivity of soil apparently some operators continue to mine soil by using erosive farming practices which offer higher yields currently some practices for reducing soil erosion may impose a double penalty on farmers in the form of lower yields and higher costs currently these detriments to short run profits may discourage farmers from adopting methods of soil conservation however farm operators who ignore the long term effects of erosion may be mortgaging the future in their pursuit of current profits

valuing environmental functions tropical wetlands recent studies have suggested that tropical wetland systems may have a crucial economic role to play in development the following paper provides an overview of these benefits using the general framework of cost benefit analysis as the methodological approach to assessing wetland values an analysis of trade offs between conserving or converting tropical wetlands demonstrates that taking into account the opportunity cost of wetland loss leads to a lower level of conversion than would otherwise be the case finally the paper discusses the extensions and limitations of the production function approach as applied to valuing nonmarketed wetland benefits

valuing public goods a comparison of survey and hedonic approaches although the theory of public goods has progressed rapidly since paul samuelson s seminal article the empirical measurement of the value of demand for public goods only recently has received increased attention perhaps the best known and most widely accepted empirical approach has been the use of hedonic prices wherein for example it is assumed that either wages or housing values reflect spatial variation in public good characteristics of different communities this indirect approach based on theoretical work of charles tiebout kelvin lancaster sherwin rosen and others has proven quite successful among public goods or bads which have been valued using the hedonic approach are climate i hoch air pollution robert anderson and thomas crocker d harrison and d rubinfeld social infrastructure r cummings et al and other community characteristics such as noise level j nelson and ethnic composition ann schnare an alternative approach is to directly ask households or individuals to state their willingness to pay for public goods using survey techniques despite arguments that strategic bias will invalidate survey results there exists the need for an alternative to the hedonic approach as an example consider the case of a remote and unique scenic vista valuable to recreators which is threatened by air pollution from a proposed coal fired plant a typical situation in the western united states although it is possible in principle to impute the value of clean air and visibility from the relative decline in local visitation which might follow construction of a power plant information on the value of visibility at the site is needed prior to construction for socially optimal decision making on plant location and pollution control equipment the hedonic approach is unavailable both because the scarcity of local population as opposed to recreators makes use of wage or property value data impossible and because scenic vistas may themselves be unique for these reasons a randall et al first applied survey methods for valuing visibility and other environmental effects of large coal fired power plants in the four corners region of new mexico since this initial application the survey approach has been widely used to value environmental commodities where market data for hedonic analysis is difficult to acquire see for example brookshire ives and schulze rowe et al brookshire et al other early attempts to value public goods using the survey approach include r davis peter bohm and j hammack and g brown although results of using the survey approach for estimating the value of public goods appear to be internally consistent replicable and consistent with demand theory see schulze et al little work on external validation has been reported thus the purpose of this paper is to report on an experiment designed to validate the survey approach by direct comparison to a hedonic property value study the los angeles metropolitan area was chosen for the experiment because of the well defined air pollution problem and be assistant professor university of wyoming assistant professor university of missouri rolla associate professor university of wyoming and professor university of wyoming respectively the research reported here was funded under a grant methods development for assessing air pollution control benefits from the u s environmental protection agency we would like to give special thanks to alan carlin and shelby gerking for their helpful suggestions and contributions additional helpful comments were received from a myrick freeman iii john tschirhart and james murdoch all conclusions are of course our sole responsibility

economic valuation of biodiversity a comparative study abstract in recent years an intensive debate on the economic valuation of biodiversity has entered the environmental economics literature the present paper seeks to offer first a critical review of key concepts that are essential for a proper understanding of such evaluation issues particular attention is given here to various monetary valuation approaches and to comparative i e meta analytical methods from the perspective of conservation and sustainable use of biodiversity several illustrative examples are presented in order to highlight the usefulness of the various approaches discussed next an attempt is made to infer general findings and lessons from past applied research by means of meta analysis in this context a multi dimensional technique originating from the field of artificial intelligence is deployed it allows us to identify the most important variables responsible for changes in economic estimates of biodiversity

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

sequestration offsets versus direct emission reductions consideration of environmental co effects abstract atmospheric greenhouse gas accumulation and consequential temperature increase can be remedied by emission reductions or agricultural carbon sequestration both options have direct and external environmental effects this paper examines the magnitudes of existing estimates of corresponding external co effects and how they could affect optimal combination of emission reductions and agricultural carbon sequestration we discuss whether government intervention in the form of taxation subsidization is justified for internalizing the externalities considering their relative magnitudes implementation costs and potential benefits that could be derived from such intervention we conclude that the existing estimates of external benefits from sequestration and emission reduction do not provide enough support for allocating resources to alter the market mix of carbon sequestration and direct emission reduction strategies

the economic effects of energy price shocks large fluctuations in energy prices have been a distinguishing characteristic of the u s economy since the 1970s turmoil in the middle east rising energy prices in the u s and evidence of global warming recently have reignited interest in the link between energy prices and economic performance this paper addresses a number of the key issues in this debate what are energy price shocks and where do they come from how responsive is energy demand to changes in energy prices how do consumers expenditure patterns evolve in response to energy price shocks how do energy price shocks affect u s real output inflation and stock prices why do energy price increases seem to cause recessions but energy price decreases do not seem to cause expansions why has there been a surge in the price of oil in recent years why has this new energy price shock not caused a recession so far have the effects of energy price shocks waned since the 1980s and if so why as the paper demonstrates it is critical to account for the endogeneity of energy prices and to differentiate between the effects of demand and supply shocks in energy markets when answering these questions

leaving the mainstream behind uncovering subjective understandings of economics instructors roles in the wake of the economic crisis a number of student organizations and researchers highlighted the lack of pluralism and heterodox approaches in economics curricula the relevance of pluralism becomes clear once set within the implications of a given scientific discourse on reality e g economics and policy making this study explores the role of instructors in co constructing the pluralism discourse and debates while recognizing the role of institutional obstacles to change within the discipline an empirical field study is conducted with lecturers in introductory economics courses at the wu vienna university of economics and business where they place themselves within the pluralism discourse via a q study a mixed method employed for studying subjectivity in socially contested topics in q a set of statements undergo a sorting procedure on a relative ranking scale followed by factor rendering four voices are identified moderate pluralist mainstreamers responsible pluralists and applied pluralists the implications of their ideas are discussed from the viewpoint of discursive institutionalism stressing the role of ideas and discourse in institutional change although a discursive readiness for changes towards more pluralism is claimed strategies for overcoming the difficulties on the institutional level need to be developed

self interest altruism and health risk reduction an economic analysis of voting behavior while classical economic theory suggests that the demand for private goods is motivated by economic self interest a growing body of literature suggests that the demand for public goods is driven both by self interest and by altruistic motives the political arena has been a major testing ground for this hypothesis recently a number of studies have tried to empirically isolate and determine the importance of economic versus ideological factors in explaining political choices by representatives kau and rubin 1979 peltzman 1984 kalt and zupan 1984 while congressional voting records have provided a rich source of data for empirical analysis a consensus opinion on the importance of self interest versus altruism has not been reached and remains controversial altruistic motivations have also been

the market value of water in the ogallala aquifer the ogallala aquifer also known as the ogallala formation or the high plains aquifer is a 174 000 square mile body of water that underlies parts of colorado kansas nebraska new mexico oklahoma south dakota texas and wyoming the ogallala contains about 3 5 billion acre feet of water symposium ii 1984 but in many areas the aquifer has been declining from continued deep well pumping sloggett and dickason 1986 the aquifer receives little recharge especially in the southern portion and as such represents a finite nonrenewable resource stock as a result of the concerns of residents of the high plains states over declines in the ogallala aquifer congress authorized the secretary of commerce to conduct a six state regional resources study of the ogallala in 1976 high plains associates 1982 the study indicated even under the most effective water conservation program more than a million acres of farmland then

timber harvest adjacency economies hunting species protection and old growth value seeking the dynamic optimum abstract forests have the potential to provide ecosystem services timber mature growth aesthetics and wildlife and endangered species protection forest managers are faced with complex ecosystem management decisions due to competing and complementary social values and differential interactions of these social values with timber production as a result management strategies can have dramatic aggregate and intertemporal welfare implications this paper portrays the trade offs and externalities in choosing or changing the forest management objective and the resulting rankings of management policies in addition the paper analyzes the role of economies of scale in harvest area where larger harvest areas generate average cost savings in harvesting and reseeding thereby promoting more intensive harvesting at the expense of environmental benefits

sensitivity of contingent valuation to alternative payment schedules insensitivity to payment schedule wherein respondents do not adequately differentiate between a one time payment and a series of payments may be an important but often overlooked factor in the design interpretation and use of contingent valuation studies several contingent valuation experiments involving a familiar private good and a less familiar environmental commodity indicate that although respondents distinguished between lump sum and periodic payment schedules implicit discount rates were very high suggesting that sensitivity to payment schedule is an important subject for further study

economic behavior under uncertainty a joint analysis of risk preferences and technology a method is developed to estimate jointly risk preferences and technology under general conditions the approach is illustrated in an application to the analysis of u s corn soybean acreage decisions over time the results provide useful information on the nature of farmers risk preferences and on the influence of price risk and production risk on acreage allocation and farmers welfare copyright 1996 by mit press

accommodating indigenous cultural heritage values in resource assessment cape york peninsula and the murray darling basin australia in this paper we consider the problem of accommodating indigenous cultural heritage values in resource assessment and valuation we suggest a need for price based approaches to valuation to be replaced by or complemented with quantitative constraints on the decision space reflecting the requirement that rights should not be violated

test retest reliability of the contingent valuation method a comparison of general population and visitor responses the reliability of the contingent valuation method is evaluated by resurveying the same general households and visitors nine months after their original survey test retest correlations on willingness to pay are statistically significant and ranged from 422 for the general population sample to 782 for the visitor sample using a paired t test there was no statistical difference between an individual s first and second reported willingness to pay chow tests comparing the original and resurvey willingness to pay functions showed no statistical difference at the 01 level reported willingness to pay is reasonably stable over the time period surveyed

expected encounters and willingness to pay for outdoor recreation there is increasing interest in the management of natural resources for recreational activities much of it concerning the effect of crowding in outdoor recreation earlier work outlined models for estimating the effect of increased visitor contacts on individual willingness to pay for wilderness experiences cicchetti and smith 1973 others have looked at how crowding affects recreational resource valuation and criteria for the optimal management of recreational resources anderson and bonsor 1974 fisher and krutilla 1972 while the present paper is also concerned with the effect of visitor contacts on willingness to pay for outdoor recreation it differs from earlier work by looking at how individual willingness to travel is influenced by pre trip expectations of interparty encounters at the site we begin the paper by reviewing the related literature concerning user contacts and outdoor recreation the next section discusses the methods employed in this study and presents the empirical results based on data from the high peaks area of the adirondack mountains in new york state the final section discusses the results and our conclusions

clubmed cyclical fluctuations in the mediterranean basin we investigate the similarities of macroeconomic fluctuations in the mediterranean basin and their convergence a model with three geo political indicators covering the west the east and the mena portions of the mediterranean characterizes well the historical experience since the early 1980 convergence and divergence coexist in the region and are reversible except for the west domestic cyclical fluctuations are still due to national and idiosyncratic causes the outlook for the next few years looks rosier for the mena and the east blocks than for the west

what to value and how ecological indicator choices in stated preference valuation the ecological literature accepts that many policy outcomes cannot be observed directly and must be characterized using indicators multiple indicators can often be used to communicate similar ecological outcomes previous studies using alternative indicators in stated preference surveys suggest that welfare estimates may be indicator dependent casting doubt on whether welfare estimates are sufficiently reliable for cost benefit analysis we suggest that the reason for such indicator dependence may be that indicators used in these prior studies represented different outcomes valued by respondents this possibility underscores the need for greater attention to selection of indicators and their properties within stated preference survey design this paper develops a model introducing the concept of outcome equivalent indicators defined as indicators that provide alternative representations of identical underlying outcomes to assess empirically whether welfare estimates are indeed robust to indicator choice when alternative indicators are expected to be outcome equivalent we analyze data from a choice experiment estimating willingness to pay for migratory fish restoration in rhode island usa results demonstrate that welfare estimates are robust to the use of alternative ecological indicators within stated preference scenarios

international spillovers in macrofinancial linkages and the decoupling phenomenon abstract this paper contributes to the debate on the decoupling of emerging economies ees from advanced economies aes by measuring how the resilience of ees to external shocks i e shocks spreading from aes has changed over time and whether ees are relatively more vulnerable to real or financial external shocks a time varying panel var model with factorisation of the coefficients was used to perform counterfactual experiments over a period of about 30 years for a large sample of countries allowing for time varying coefficients permitted the decoupling phenomenon to be examined as a slow moving evolution process over a long time rather than as a structural break at a specific moment the factorisation of coefficients allowed a large dynamic panel to be managed with interdependences across many countries consequently the experiment was more realistic in terms of evaluating the response of ees to shocks hitting the aes within a global framework the resilience of ees has improved over time however this increasing resilience was discontinuous over the approximately 30 year sample period tracing a wave path in the whole sample period the ees were relatively more vulnerable to credit shocks than to real ones this greater vulnerability increased over time and peaked in the last 5 years of the sample period

unintended impacts of public investments on private decisions the depletion of forested wetlands by affecting relative economic returns infrastructure investments can induce major changes in private land use the authors find that 30 percent of forested wetland depletion in the mississippi valley has resulted from private decisions induced by federal flood control projects despite explicit federal policy to preserve wetlands the model aggregates individual land use decisions using a parametric distribution of unobserved land quality dynamic simulations are used to quantify the impacts on wetlands of federal projects and other factors copyright 1990 by american economic association
