substitution possibility between unpriced pulp and wastepaper in the u s paper and paperboard industry a greater use of recycled wastepaper would preserve virgin forests as well as reducing the amount of wastepaper going to landfills these environmental goals depend critically on the elasticity of substitution between pulp and wastepaper in producing paper and paperboard since most of the pulp consumed by u s paper mills and paperboard mills is transferred internally from vertically integrated pulp mills the price data on pulp is not available this paper constructs an econometric model which enables us to estimate the substitution possibility between unpriced pulp and wastepaper in the u s paper and paperboard industry empirical results show that the elasticity of substitution between unpriced pulp and wastepaper is positive but not statistically significant

individual risk attitudes measurement determinants and behavioral consequences this paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects homes using a question asking people about their willingness to take risks in general we find that gender age height and parental background have an economically significant impact on willingness to take risks the experiment confirms the behavioral validity of this measure using paid lottery choices turning to other questions about risk attitudes in specific contexts we find similar results on the determinants of risk attitudes and also shed light on the deeper question of stability of risk attitudes across contexts we conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks occupational choice and smoking the question about risk taking in general generates the best all round predictor of risky behavior

alternative models of input allocation in multicrop systems irrigation water in the central plains united states abstract this paper compares three models of input allocation in multicrop systems in addition to the variable input and satisficing models analyzed in previous research an allocatable fixed input model of short run input use is derived the empirical application studies irrigation water use in the central plains region of the united states based on results from model specification tests and prediction accuracy measures the allocatable fixed input model dominates both other models in explaining multicrop water allocation in addition the paper presents an alternative approach to the study of deficient data on multicrop production by transferring econometric results from analysis of non deficient crop level data input allocations in deficient data sets can be predicted

a utility consistent combined discrete choice and count data model assessing recreational use losses due to natural resource damage abstract a two stage budgeting approach can often be taken when analyzing consumer choice situations in this paper we examine the particular situation where a consumer makes purchases of a discrete commodity of which there are a number of brands in the first stage the consumer decides how many purchases to make in the second stage the consumer decides how to allocate these purchases across brands our econometric approach to this type of situation uses a utility consistent combined discrete choice and count data model the second stage which is specified as a multinomial choice model produces a price index for the commodity which is used to estimate the first stage which is specified as a count data model we apply the model to recreational demand behavior in alaska in order to estimate the welfare losses suffered by recreational users due to the exxon valdez oil spill these results may provide useful input to government agencies attempting to estimate the appropriate level of taxes fines or regulations for deterring damage to the environment

do professional traders exhibit myopic loss aversion an experimental analysis two behavioral concepts loss aversion and mental accounting have been combined to provide a theoretical explanation of the equity premium puzzle recent experimental evidence supports the theory as students behavior has been found to be consistent with myopic loss aversion mla yet much like certain anomalies in the realm of riskless decision making these behavioral tendencies may be attenuated among professionals using traders recruited from the cbot we do indeed find behavioral differences between professionals and students but rather than discovering that the anomaly is muted we find that traders exhibit behavior consistent with mla to a greater extent than students

economic performance of flexible functional forms a correction and comment in a recent article in the european economic review kostas a despotakis 1986 examines the properties of flexible functional forms applying the concept of the inner domain in the numerical experiments he unfortunately uses an incorrect form of the transcendental logarithmic function when the correct functional form is used his experimental results are always weakened and sometimes invalidated in particular the dinerences between the considered flexible functional forms are smaller than his experiments would suggest while the importance of dillerences in the elasticity of substitution is strengthened i introduction

testing the stochastic structure of production a flexible moment based approach conventional production function specifications are shown to impose restrictions on the probability distribution of output that cannot be tested with the conventional models these restrictions have important implications for firm behavior under uncertainty a flexible representation of a firm s stochastic technology is developed based on the moments of the probability distribution of output these moments are a unique representation of the technology and are functions of inputs large sample estimators are developed for a linear moment model that is sufficiently flexible to test the restrictions implied by conventional production function specifications the flexible moment based approach is applied to milk production data the first three moments of output are statistically significant functions of inputs the cross moment restrictions implied by conventional models are rejected

decision making with naive advice in many of the decisions we make we rely on the advice of others who have preceded us for example before we buy a car choose a dentist choose a spouse find a school for our children sign on to a retirement plan etc we usually ask the advice of others who have experience with such decisions the same is true when we make major financial decisions here people easily take advice from their fellow workers or relatives as to how to choose stock balance a portfolio or save for their child s education although some advice we get is from experts most of the time we make our decisions relying only on the rather uninformed word of mouth advice we get from our friends or neighbors we call this aive advice in this paper i will outline a set of experimental results that indicate that word of mouth advice is a very powerful force in shaping the decisions that people make and tends to push those decisions in the direction of the predictions of the rational theory

vertical integration in the u s pulp and paper industry 1900 1940 a transaction cost model of vertical integration is tested based on detailed descriptions of every pulp and paper mill operating in the united states between 1900 and 1940 this study contributes to the literature on integration through the use of a large disaggregated database that allows identification of individual mills over time vertical integration of pulp and paper production is found to be positively associated with regional concentration paper mill capacity and production of standardized grades of paper over time new entrants behaved differently than established mills because few mills switched between integration and specialization once established copyright 1994 by mit press

cheap talk and investment rivalry in the pulp and paper industry determinants of the abandonment of previously announced capacity expansions are analyzed in eleven industries within the north american pulp and paper sector given the investor s initial confidence extent of precommitment of resources and post announcement fresh news abandonment s likelihood increases with unanticipated projects subsequently announced by rivals the process suggests a continual auction with the winning projects and firms having certain systematic properties unexpected announcements by rivals promote abandonment only in less concentrated industries elsewhere completion is actually encouraged short run price competition is found highly sensitive to capacity utilization and the market s geographic scope is tested

comparing time series and survey forecasts of weekly changes in money a methodological note measured as the difference between the announced change and the expected change derived from the money market services inc weekly survey of government securities dealers unlike other survey measures of expectations the most notable example of which is the livingston survey data these expectations are formed by active market participants consequently the survey s forecast made public before the fed s announcement of the actual change in the money stock is commonly thought to represent the market s expectation the concern in this paper is not with the impact of unanticipated money changes on nominal interest rates the purpose is to compare the relative forecasting abilities of the survey predictions and those obtained from a timeseries model this question is of interest because the weekly money series used in previous research includes certain abnormal weeks in which exogenous factors may significantly alter the series stochastic properties see for example cornell 1 urich and wachtel 9 thus the influence of these abnormal weeks weeks that include benchmark revisions changes in seasonal factors and weeks in which there is a social security effect is examined by comparing forecasting results for two samples one includes these weeks and the other deletes them following pearce 6 this approach allows us to test the hypothesis that the survey responses are at least weak form rational and to see how sensitive this test is to the sample of weeks used unlike previous studies we use two survey forecast series the median forecast made public prior to the announced change in ml and the mean series constructed from individual respondents forecasts zarnowitz s 10 examination of the asa nber survey forecasts indicates that the mean forecast is on average statistically superior to the median this finding is based on the idea that the mean forecast uses a more informationally diverse data set consequently it is

nonlinear strategies in dynamic duopolistic competition with sticky prices abstract we discuss nonlinear strategies in an infinite horizon duopoly game with sticky prices where firms maximize their discounted sum of profit we construct a stationary feedback equilibrium without guessing value functions and feedback strategies that solve the hamilton jacobi equation for this purpose we study the auxiliary equation that is derived from the hamilton jacobi equation we show that the domain of the state space plays an crucial role in characterizing feedback equilibria and discuss several implications of this observation in particular we find that when the upper bound of the state space is not very high previously unknown feedback equilibria emerge

cooperative solution of local externality problems a case of mechanism design applied to irrigation abstract cooperative solutions to ameliorate externalities may be pareto superior compared to noncooperative abatement strategies but such solutions may not be adopted without appropriate institutional mechanisms to achieve cooperative outcomes voluntarily there must be methods of determining cost shares and identifying preferred solutions here the design of a process and a related algorithm are proposed based on concepts of welfare economics and game theory for public goods and externalities simulation of the process for an irrigation externality problem in the central valley of california demonstrates existence of a unanimously preferred solution with improved water quality

are you risk averse over other people s money decisions with uncertain outcomes are often made by one party in settings where another party bears the consequences whenever an individual is delegated to make decisions that affect others such as in the typical corporate structure does the individual make decisions that reflect the risk preferences of the party bearing the consequences we examine this question in two simple settings lottery choices and sealed bid auctions using controlled laboratory experiments we find that when an individual makes a decision for an anonymous stranger there is a tendency to exhibit less risk aversion this reduction in risk aversion is relative to his or her own preferences and it is also relative to his or her belief about the preferences of others this result has significant implications for the design of contracts between principals and agents

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

quasi fixed inputs in u s and japanese manufacturing a generalized leontief restricted cost function approach in this paper a generalized leontief variable cost function is develope d which permits analytical derivation of steady state levels of quasi fixed inputs and capacity output and does not require specification of a numeraire input this framework is then used to evaluate the fa ctor demand patterns of japanese and u s manufacturing based on bot h one quasi fixed capital input and two quasi fixed capital and la bor input specifications and both static and dynamic optimization t he findings provide evidence of considerable flexibility of demand re sponses in japan which may have contributed to japan s relatively st rong economic performance in the volatile 1970s copyright 1988 by mit press

the externalities associated with the common property exploitation of groundwater abstract in this paper the rate of groundwater extraction under the common property arrangement is the outcome of a dynamic game played with feedback strategies the analysis clarifies the externalities associated with the common property extraction of groundwater and identifies an risk externality that arises when firms are risk averse identifying the various externalities bears on the development of appropriate forms of groundwater management in particular the risk externality would be unknown to the watermaster of a central control agency suggesting the need for creative decentralized forms of groundwater management

the demand for irrigation water in the high plains of texas 1957 80 a new method of calculating groundwater pumpage is used to estimate water demand these results are used via the gisser sanchez model to show that pumpage regulation is unlikely to be beneficial in the texas high plains a sensitivity analysis is performed on present value profits under optimal control and competitive schemes using different water demand slope and intercept values the results indicate that the gisser sanchez rule is useful in determining the divergence in pumpage time paths and percentage difference in profits under the two schemes but it is not insightful in determining the nominal difference in profits

looking at the cost side of monopoly welfare loss under oligopoly is defined as that part of consumer surplus which is lost and not regained by higher profits in a model with asymmetric firms this implies that the total welfare loss consists of the deadweight loss triangle plus a cost side inefficiency effect due to the fact that in imperfect markets not all firms utilize the lowest cost technique using a flexible cv model we calculate these effects empirically for two relatively homogeneous industries pulp paper and cement the deadweight loss triangles are shown to be smaller than the cost difference effect the staircase for these industries

heterogeneity in risky choice behaviour in a broad population we analyse risk preferences using an experiment with real incentives in a representative sample of 1 422 dutch respondents our econometric model incorporates four structural parameters that vary with observed and unobserved characteristics utility curvature loss aversion preferences towards the timing of uncertainty resolution and the propensity to choose randomly rather than on the basis of preferences we find that all four parameters contribute to explaining choice behaviour the structural parameters are significantly associated with socio economic variables but it is essential to incorporate unobserved heterogeneity in each of them to match the rich variety of choice patterns in the data

hedonic price analysis and selectivity bias hedonic valuation of quality attributes can be misleading when theassumption that these attributes are exogenous to sample selection isviolated this paper considers the simultaneity between hedonic valuationand sample selection in the context of a model of producer behavior andinvestigates empirically the case where land is demanded for use as an inputeither in agricultural production or in touristic development the empiricalanalysis suggests that failing to correct for sample selection results in abiased valuation of the effect of water salinity on agricultural land

optimal management of a confined groundwater system abstract dynamic programming is applied to a relatively simple economic and hydrologic model of a confined aquifer system in southwest montana to determine an optimal interseasonal allocation schedule the derived decision rule demonstrates the economic advantage of maintaining a confined groundwater system while localized intraseasonal loss of the artesian pressure may occur it is important to maintain this pressure from year to year because of its role in reducing extraction costs the welfare gap as measured by differences in the net present value of economic returns to the basin under an optimal use policy versus an uncontrolled common pool situation is not trivial sensitivity analysis indicates that assumptions about uniformity of land productivity vis a vis their impact on the shape of the returns function the discount rate and the level of electric power rates are particularly critical with respect to the magnitude of the commonality problem

production and cost in the us paper and paperboard industry the us paper and paperboard industry has experienced significant structural changes over the past 25 years including reductions in the number of mills lower rates of capacity growth employment cutbacks and a loss of market share to foreign competitors these structural shifts portray an industry that increasingly has difficulty adapting to a more competitive global environment based on aggregate data from 1965 to 1996 this article estimates a short run translog tl cost function for the industry the estimated model fits the data well and all sample points satisfy monotonicity and concavity conditions at all points among the findings the industry operates at slightly increasing returns to capital utilization and labour and energy are allen uzawa complements but morishima substitutes in production technological progress generated 0 02 reduction in annual operating costs and consistent with an ailing us industry estimated marginal costs approximated average operating costs until 1982 after which

an experiment on risk taking and evaluation periods does the period over which individuals evaluate outcomes influence their investment in risky assets results from this study show that the more frequently returns are evaluated the more risk averse investors will be the results are in line with the behavioral hypothesis of myopic loss aversion which assumes that people are myopic in evaluating outcomes over time and are more sensitive to losses than to gains the results have relevance for the equity premium puzzle and also for the marketing strategies of fund managers

the travel cost model for lake recreation a comparison of two methods for incorporating site quality and substitution effects this paper empirically illustrates how different assumptions regarding recreationists decision making behavior affect the predicted changes in recreational activity given a water quality improvement a multinomial logit model which reallocates visits away from other sites to the improved site predicts a smaller outward shift of the recreationist s demand curve than the more traditional travel cost model which does not assume any reallocation of visits among sites

bubbles and financial professionals the efficiency of financial markets and their potential to produce bubbles are central topics in academic and professional debates yet little is known about the contribution of financial professionals to price efficiency we run 116 experimental markets with 412 professionals and 502 students we find that professional markets with bubble drivers capital inflows or high initial capital supply are susceptible to bubbles although they are more efficient than student markets in mixed markets with students bubbles also occur but professionals act as price stabilizers we show that heterogeneous price beliefs drive overpricing especially in bubble prone market environments

simulating the effects of railroad mergers the purpose of the study reported in this paper is to add to the empirical literature concerning market power and competition between railroads in particular the paper examines the effect of railroad mergers on railroad market power this is achieved through a case study of the transportation market for the export of kansas wheat to houston texas the models techniques and general conclusions of the study can be applied to similarly situated regional transportation markets for homogeneous goods such as coal ores field crops and lumber two models are developed to achieve the objectives of the study a network model of the wheat logistics system is used to identify the least cost transportation routes from the kansas study area to the market at houston a profit improvement algorithm which identifies nash equilibrium prices is developed to measure the amount by which railroads can profitably raise their prices above variable cost the results of the study have implications for united states railroad merger policy the paper indicates that railroad mergers do not necessarily increase railroad market power or make railroad shippers worse off instead the study demonstrates that the impact of railroad mergers on shippers and railroads depends on factors that vary geographically such as the degree of intrarailroad and intermodal competition in the area

stereotypes and false consensus how financial professionals predict risk preferences abstract we analyze the prediction of risk preferences of others using an artefactual field experiment with financial professionals and students for their prediction the subjects receive information on multiple demographic characteristics and a self assessment of risk taking of the target when analyzing the predictions we find three significant effects subjects use the demographic information for stereotyping as well as the target s self assessment on risk taking and we find a considerable false consensus effect the false consensus effect is the strongest for experienced professionals regarding the prediction s accuracy we find that the forecasts of the professionals are more accurate than the forecasts of the students

implicit prices of soil characteristics for farmland in iowa arguments have long persisted that purchasers pay too much for poor land i e less productive more erosive relative to the higher quality counterpart in other words purchasers are either irrational or poorly informed relative to the differences in land productivity between poor and good farmland similar arguments have been advanced concerning the willingness to pay rent on the part of tenant operators little empirical evidence exists to support or reject this hypothesis farmland appraisals are sometimes cited as evidence to support the contention but such empiricism may indicate more about the quality and biases of appraisers than about the behavior or efficient functioning of the farmland market resolution of this issue is extremely important to the formation of soil conservation policy designed to protect soil productivity irrational behavior on the part of land purchasers may lead one to infer that the market system is failing to recognize adequately the soil productivity consequences of soil erosion if this oversight consistently leads to excessive soil erosion from society s perspective then some form of government intervention may be necessary to protect the welfare of society assuming that such intervention is capable of correcting the market failure

groundwater focusing on the real issue most studies of the welfare economics of groundwater have focused mainly on the dichotomy between optimal control of groundwater use and no control at all this article argues that under circumstances that generally prevail in semiarid zones assigning property rights to groundwater and permitting the market to determine the allocation of water use can lead to a second best solution an argument is made that if potential users would be allowed to coase bargain with incumbent users on the issuance of new groundwater rights the second best solution is elevated to a pareto optimal solution this article is also a tale of two states water law and performance in new mexico and arizona

current issues in the economics of groundwater resource management the issue of groundwater management remains a practical concern in many regions throughout the world while water managers continue to grapple with the question of how to manage this resource in this article we attempt to bring the most advanced and appropriate tools to bear on the issue of resource allocation involving groundwater our objective is to demonstrate the state of the art in the literature on ways to think about this complex resource and to deal with the important economic issues emanating from its complexity we present the conceptual framework within which economists examine the elements interacting in the management of groundwater resources indicate why the role of the market is limited with respect to the price of this very complex resource and point to the mechanisms that can pull competitive groundwater price and quality graded quantity of groundwater in line with their equilibrium levels in particular we critically review economic models of groundwater use examine the potential for groundwater management discuss the difficulties encountered in the estimation of the relevant control variables of such models and identify the advantages and limitations of the instruments devised for the efficient use allocation of this resource finally we argue that devised regulatory schemes usually ignore the information and knowledge needed for their implementation and we suggest a core of conditions necessary for successful groundwater management reforms

choice modelling approaches a superior alternative for environmental valuation in this paper we examine some popular choice modelling approaches to environmental valuation which can be considered as alternatives to more familiar valuation techniques based on stated preferences such as the contingent valuation method a number of choice modelling methods are consistent with consumer theory and its focus on an attribute based theory of value permits a superior representation of many environmental management contexts however choice modelling surveys can place a severe cognitive burden upon respondents and induce satisficing rather than maximising behavioural patterns in this framework we seek to identify the best available choice modelling alternative and investigate its potential to solve some of the major biases associated with standard contingent valuation we then discuss its use in the light of policy appraisal needs within the eu an application to the demand for rock climbing in scotland is provided as an illustration

uncertainty and irreversibility in groundwater resource management abstract optimal exploitation of renewable groundwater resources when extraction affects the probability of occurrence of an irreversible event is studied the term irreversible signifies that the event occurrence renders the resource obsolete it is found that uncertainty concerning the event occurrence has a profound effect under certainty when the stock level below which the event occurrence has a profound effect the optimal state process converges to a unique equilibrium state under uncertainty when the event occurrence level is unknown we identify equilibrium intervals and show that optimal processes initiated elsewhere converge to a boundary of one of these intervals inside an equilibrium interval the expected loss due to the event occurrence is so high that it does not pay to extract in excess of recharge even though under certainty doing so would be beneficial

price margins and capital adjustment canadian mill products and pulp and paper industries abstract the purpose of this paper is to estimate a model incorporating non competitive behaviour in product and factor markets in addition capital accumulation is subject to adjustment costs so that firms are not constrained to be in long run equilibrium the model is applied to two major canadian manufacturing industries pulp and paper and mill products the results show for both industries in each of three product markets and the wood input market that there is competitive behaviour in addition the industries are not in long run equilibrium as marginal adjustment costs cause marginal profit to exceed the rental rate on capital with the industries exhibiting short run competitive behaviour in product and factor markets new estimates are derived for scale economies and rates of technological change unlike the results from other studies both industries exhibit small scale economies and positive rates of technological change

valuing a fishing day an application of a systematic varying parameter model deciding how to allocate forage among animals is a fundamentally important process in range management the wisdom of these decisions can be enhanced by estimating the marginal value of forage needed by competing species we present a method for

economic performance of flexible functional forms flexible functional forms are well behaved over restricted regions the outer domain and constitute good approximations of a hypothetical true technology set of preferences over only a subregion of the outer domain the inner domain comparison of such forms has been made in terms of outer domain ideally il should also cover the inner domain by definition however the inner domain is unquantifiable instead functions representing producer technology consumer preferences can be characterized and compared in terms of what we call in this paper economic performance focusing on the producer side we demonstrate that relative differences and associated implications for equilibrium modeling can be substantial

inflation and relative price variability in the open economy this paper explores the determination of relative price variability in a small open economy operating under a fixed exchange rate a central ingredient of the model presented is the distinction made between traded and non traded goods this distinction leads to a decomposition of total variability into three components the variabilities within each set of goods and between the two sets the analysis also emphasizes the effects of expected versus unexpected inflation on the variability of relative prices the model is tested using annual data for mexico covering the 1951 76 period

the impact of price risk on sow farrowings 1967 78 several studies have attempted with varying degrees of success to quantify price risk variables for crops at various levels of aggregation just behrman traill and lin price risk in particular market situations is an empirical issue and difficult to predict ex ante several factors suggest the potential for a risk response in sow farrowings the limited ability of hog futures market prices to forecast subsequent cash prices leuthold and hartman martin and garcia indicates that the level of uncertainty about future price is high this coupled with livestock producers reticence to use the futures market as a hedging mechanism leuthold suggests that producers exposure to existing price risk may be prevalent this analysis quantitatively examines the importance of input and output price risk on aggregate sow farrowings first the price risk model is reviewed briefly then a conventional adaptive expectations model is used to develop price and risk variables alternative definitions of risk are assessed finally futures prices are used to generate expected price and risk variables

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

railroad rate deregulation and uncertainly of farm level prices for corn uncertainty of country elevator prices for corn in terms of error variance and mean squared forecast errors failed to increase in response to the deregulation in 1980 of railroad rates regression analysis was used to separate the uncertainty impacts of deregulation from those of other unanticipated changes in supply and demand factors influencing uncertainty included unexpected changes in storage costs export demand corn futures and rail car utilization some of the factors creating price uncertainty prior to deregulation were replaced by new uncertainty factors occurring as a result of deregulation

portfolio theory and the demand for futures the case of california cotton this paper examines the simultaneous choice of cropping patterns and futures positions it derives the demand for hedging as a function of the price of a hedge and the crop choice set it estimates these functions for california cotton farmers it finds that both the costs of hedging and the opportunity to diversify risk by growing other crops substantially change the optimal hedge for california cotton farmers

on estimating dynamic factor demands many recent empirical studies on inter related factor demands involve factor demand functions whose arguments depend on the researcher s arbitrary normalization rule this paper shows how sensitive the estimated elasticities are to the various normalizations that are possible alternatives that are not dependent on a normalization are suggested

a theoretical foundation for count data models the paper develops a theoretical foundation for using count data models in travel cost analysis two micro models are developed a restricted choice model and a repeated discrete choice model we show that both models lead to identical welfare measures

basis risk measurement and analysis of basis fluctuations for selected livestock markets unanticipated basis changes can reduce the ability of futures markets to transfer risk and can affect income levels of producers and market participants this study examines short term basis risk defined as the variance of the random component of the basis over time for several midwest livestock markets basis risk is related to several factors influencing the long term pattern in the time series and unexpected changes in price little evidence is found that basis risk changed as maturity approached or that risk varied across markets except for the interior iowa hog market

valuing the future one of the most controversial areas of economics is the practice of discounting attaching a lower weight to future costs and benefits than present costs and benefits discounting appears to offend notions of sustainable development and the interests of future generations recent advances in the theory of discounting hold out strong hope that the tyranny of discounting can be avoided through the use of time varying discount rates tvdrs this paper reviews the recent rationales for tvdrs and applies the results to issues such as nuclear power and global warming control

agricultural land markets and soil erosion policy relevance and conceptual issues farmland values dwarf all other asset values in agricultural production therefore understanding the formation and roles of farmland prices should command high research priority while we have seen some clarification of the pricing of farmland through time from an aggregate perspective other questions remain enigmas one is the relationship among land prices soil erosion and conservation investments understanding that relationship is critical to designing effective public soil conservation policy in the past the notion that the farmland market was generally not sensitive to varying erosion conditions was seemingly endorsed without systematic data analysis miranowski and hammes note the paucity of good empirical evidence for testing the effect of erosion on farmland prices two probable reasons for this lack of empirical study are worth citing first the legitimacy of public soil conservation assistance programs was not challenged then unlike the present thus there was not a compelling social need to understand whether farmland markets were transmitting proper signals to landowners with regard to erosion s effects second thorough and rigorous empirical tests of the relationship between land prices and erosion or conservation conditions are painstakingly detailed work fraught with many conceptual and measurement complications this paper has three sections in the first the policy context surrounding land prices and soil erosion is discussed we then report some empirical work on the erosion land price question with emphasis on specification issues surrounding an implicit price model implications for soil conservation policy and further research close the discussion

voluntary environmental agreements good or bad news for environmental protection abstract there has been growing interest in the use of voluntary agreements vas as an environmental policy tool this article uses a simple model to determine whether vas are likely to lead to efficient environmental protection we consider cases where polluters are induced to participate either by a background threat of mandatory controls the stick approach or by cost sharing subsidies the carrot approach the results suggest that the overall impact on environmental quality could be positive or negative depending on a number of factors including the allocation of bargaining power the magnitude of the background threat and the social cost of funds

non mandatory approaches to environmental protection the approach to environmental protection has been evolving from a regulation driven adversarial government push approach to a more proactive approach involving voluntary and often business led initiatives to self regulate their environmental performance this has been accompanied by increasing provision of environmental information about firms and products to enlist market forces and communities in creating a demand for corporate environmental self regulation by signaling their preferences for environmentally friendly firms this paper provides an overview of the non mandatory approaches being used for environmental protection and surveys the existing theoretical literature analyzing the economic efficiency of such approaches relative to mandatory approaches it also discusses empirical findings on the factors motivating self regulation by firms and its implications for their economic and environmental performance it examines the existing evidence on the extent to which information disclosure is effective in generating pressures from investors and communities on firms to improve their environmental performance
