dynamic corn supply functions a model with explicit optimization both static and dynamic models have been used to estimate aggregate supply elasticities for annual crops the early studies relied on static singleequation models in a few variables assumed static price expectations e g kohls and paarlberg and produced very small estimates of own price supply elasticities e g 0 07 for corn nerlove 1956 1958a and nerlove and addison showed that agricultural supply models incorporating adaptive price expectations and or dynamic resource adjustment produced larger estimates of supply elasticities for corn and other agricultural commodities additionally they showed that supply elasticities obtained from static models need not be bounded by the short run and long run supply elasticities of

simple nonparametric tests of technological change theory and application to u s agriculture several nonparametric tests of technological change are proposed conditional on alternative maintained behavioral assumptions the tests are simple as they require verification of axioms via binary comparisons that are analogous to those of the revealed preference theory our model allows a broad interpretation of technological changes yet trivial rationalization of the data with either profit maximization or cost minimization behavior is excluded the tests are applied to study the u s aggregate agricultural data supporting the hypotheses of rankable and neutral technological variations

fishing effort its testing specification and internal structure in fisheries economics and management abstract the concept of fishing effort is central to fisheries economics and management however effort is an aggregate index of inputs which can be consistently formed only under the condition on production technology of homothetic separability of inputs this paper develops the conditions under which effort can be consistently formed it then provides the first empirical test for effort and jointness in inputs in a fishery by estimating a multiproduct function for the new england otter trawl fleet after not rejecting input output separability and rejecting nonjointness in inputs the construction of a superlative index for effort is demonstrated through estimating a translog production function the implications of effort s internal structure for fisheries management are then considered

profit function approximations and duality applications to agriculture monte carlo simulations of profit functions indicate that flexible functional forms may be ranked nearly the same with respect to allen uzawa partial substitution elasticities or price and fixed factor elasticities flexible functional form approximations of output price elasticities are generally worse than approximations of input price or fixed factor elasticities minflex laurent functional forms did not appear to approximate underlying elasticities any better than did their translog and generalized leontief counterparts

fiscal policies in the world economy this paper uses a two country general equilibrium model of the world economy in order to analyze the effects of budget deficits and government spending on world rates of interest consumption and international indebtedness it demonstrates the difference between the effects of fiscal expenditures and tax cuts as well as between the effects of current policies and expected future policies it is shown that the qualitative effects of fiscal policies depend on whether the country introducing the policies runs a surplus or a deficit in its current account following the positive analysis of the short run and the steady state effects the paper concludes with a normative analysis of the welfare implications of budget deficits

bureaucratic behavior in the local public sector a revealed preference approach public sector bureaucratic utility is typically assumed to be a function ofbudget size or government employment although intuitively appealing thereare no definitive direct tests of the assumption to fill this gap thispaper exploits data that isolate resource allocation decisions made by localpublic sector bureaucrats we use revealed preference theory to find thatthe bureaucracy behaves as if bureaucratic utility is an increasingfunction of employment across government functions and public spending providing direct evidence justifying the popular assumption in theoreticalmodels of government behavior

a theory of sticky rents search and bargaining with incomplete information abstract this paper offers the first theoretical explanation of housing rent stickiness and differential stickiness by housing structure type key features of rental markets worldwide previous theoretical work on the subject is sparse and explains why some landlords charge below market rents not stickiness apart from its interest for understanding housing markets and overall inflation rent stickiness is intriguing because it shows that stickiness can emerge in markets where the typical menu cost logic does not apply and where market participants typically engage in repeated bargaining over contracts our model involves search and bargaining with incomplete information in a two period game and generates stickiness in a novel manner the key decision is the landlord s choice of whether to renegotiate or not crucially landlords do not know tenant perceptions of unit quality the key force generating stickiness is that offering the identical contract preempts tenant search thus limiting tenants outside options and resolves uncertainty early risk aversion reinforces this mechanism and yields differential stickiness by landlord type renegotiation risk for large landlords disappears because the different outcomes rent increase rent decrease and vacancy average out landlords who manage only one unit loathe vacancy and are highly motivated to avoid renegotiation

international monetary and fiscal policy cooperation in the presence of wage inflexibilities abstract this paper studies the transmission mechanisms and welfare implications of strategic monetary and fiscal policy in a two country mundell fleming variable supply stochastic model the issue of the counterproductivity of policy cooperation raised by rogoff 1985 is examined and extended to fiscal policy it is established that systematic fiscal policy cooperation is productive for a wide range of parameter values that include those of the simple keynesian model cooperation is always productive for policy that is contingent on the realisation of shocks

depreciation of housing an empirical consideration of the filtering hypothesis a ssumptions regarding the depreciation ax rate for housing play an important role in the urban economics literature 1 the notion that houses filter down from higher to lower quality is prevalent in both academic and policy discussions of the nature of urban problems yet there has been no attempt to specify which depreciation rates are appropriate to these discussions and little empirical investigation of depreciation in housing this paper presents estimates of depreciation rates for housing which are appropriate to consideration of the filtering hypothesis estimates of these depreciation rates must be pursued differently from estimates of the depreciation rates for the aggregate capital stock of housing a brief review of previous studies which points out some of the difficulties which confound observation of depreciation rates is presented in section i section ii discusses specification and section iii describes the data and estimation technique used results are presented in section iv section v is a brief conclusion

commodity price forecasting with large scale econometric models and the futures market this paper compares the accuracy of major commercial price forecasts for corn wheat soybeans soybean oil soybean meal cotton live cattle and hogs the price forecasting information in futures prices is evaluated by comparison the results among commercial forecasters are mixed but futures prices perform relatively better on average although not universally so these results have important implications for operational risk management

measuring the cost of shelter for homeowners theoretical and empirical considerations recent economic developments have aroused substantial interest in the treatment in the consumer price index cpi of the cost of shelter for homeowners from december 1977 when the latest version of the cpi was introduced until december 1980 the all items cpi increased at an average annual rate of 11 6 while the homeownership component increased at an average annual rate of 16 2 relative to all of the other goods and services in the cpi the homeownership component has increased by 17 5 over the same time period if the relative price of homeownership had remained constant the growth rate of the cpi would have been reduced to 10 1 the question which has been raised is whether the rapid relative increase in the homeownership component which has had such an important impact on the cpi truly reflects changes in the cost of shelter this question is not only important but difficult encompassing many subsidiary questions and auxiliary issues the purposes of this paper are threefold 1 to outline briefly a conceptual framework for the cpi which leads to a straightforward specification of what the shelter component of the cpi should measure 2 to evaluate the theoretical properties of alternative procedures designed to approximate this measurement objective and 3 present empirical evidence on the operational difficulties involved in pursuing a new approach to shelter cost measurement two main conclusions are reached first on both theoretical and empirical grounds a rental equivalence approach to measuring shelter costs for owner occupants is preferred second an estimated rental equivalence measure has grown more slowly over at least the past six years than the official cpi homeownership component given the way in which the cpi is used to escalate both private and public expenditures these results demonstrate that the choice of measurement technique has important distributional implications

do new york dairy farmers maximize profits or minimize costs the weak axiom of profit maximization and weak axiom of cost minimization were used to determine whether each of forty nine new york dairy farms displayed behavior consistent with profit maximization or cost minimization these were tested for each farm across eleven years of data correcting for technological change using previously estimated nonparametric malmquist productivity indices the results indicate that some were moderately successful in maximizing profits but more came closer to minimizing costs over half of the observations were within 10 of minimum costs

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

international coordination in the design of macroeconomic policy rules abstract the paper examines international issues that arise in the design and evaluation of macroeconomic policy rules it begins with a theoretical investigation of the effects of fiscal and monetary policy in a two country rational expectations model with staggered wage and price setting and with perfect capital mobility the results indicate that with the appropriate choice of policies and with flexible exchange rates demand shocks need not give rise to international externalities or coordination issues price shocks however do create an externality and this is the focus of the empirical part of the paper using a simple seven country model consisting of canada france germany italy japan the united kingdom and the united states optimal cooperative and non cooperative nash policy rules to minimize the variance of output and inflation in each country are calculated the cooperative policies are computed using standard dynamic stochastic programming techniques and the non cooperative policies are computed using an algorithm developed by finn kydland the central result is that the cooperative policy rules for these countries are more accommodative to inflation than the non cooperative policy rules

economies of scale and input substitution in public libraries abstract a translog cost function is applied to 1988 data for 194 indiana public libraries to measure economies of scale and input substitution elasticities book circulation measures library output and costs include noncapital expenditures scale economies exist for libraries with circulations up to 55 000 per year larger libraries exhibit constant returns to scale labor books and supplies services are all substitutes with inelastic own price and cross price elasticities

supply response and the dispersion of price expectations nomic an0lysis is the implication of aggregation when doing market studies the conditions for exact aggregation under a variety of definitions and settings have been studied paris and rausser theil the focus of this paper is on supply response in agriculture several authors have studied the effects of and tests for differential supply response coefficients across individuals or areas when aggregating firms e g theil p 567 here these coefficients are assumed to be identical for every firm but another problem is examined when uncertainty is present it is well documented that farmers have diverse price expectations e g bessler the question occurs as to the effects of such different expectations on aggregate supply response it is found that the curvature of the supply function is a crucial component of the analysis for example if the supply function is strictly concave an increase in the dispersion of expectations will reduce supply in aggregate

acreage decisions under risk the case of corn and soybeans an acreage supply response model is developed under expected utility maximization the resulting framework is used to specify and estimate a system of risk responsive acreage equations for corn and soybeans in the united states particular attention is given to the truncation effects of government price supports on the distribution of corn and soybean prices also a wealth variable is included in the acreage equations the empirical results indicate that risk and wealth variables play an important role in cornsoybean acreage decisions the analysis also shows that cross commodity risk reduction is important in acreage allocation decisions

nonparametric analysis of technical pure technical and scale efficiencies for food crop production in east java indonesia abstract nonparametric analysis of technical efficiency for irrigated farms in the madiun regency in the west central part of east java indonesia is conducted using linear programming techniques this procedure allows the relative technical efficiency for each farm to be determined and for inefficiencies to be decomposed into pure technical inefficiency and scale inefficiency and does not require restrictions or assumptions regarding functional form to be placed on the data farmers in madiun generally are efficient relative to each other farmers operating inefficiently do so more often because of scale inefficiencies rather than pure technical inefficiencies a majority of the farms operate in the region of decreasing returns to scale rather than increasing returns to scale farmer age the level of diversification of cropping activities and high school education were found to be related to technical efficiency in the rainy season under irrigated conditions other socioeconomic factors were not statistically significant the results imply that inefficient farms use excessive levels of inputs particularly nitrogen fertilizer this is perhaps due to the lingering effects of past input subsidization policies particularly of fertilizers in indonesia or to risk reducing behavior the results also imply that current government policies to encourage diversification of cropping practices in java may lead to greater technical inefficiencies in production in addition extension education targeted to younger farmers with low levels of formal education would improve efficiency

on nonparametric supply response analysis in this paper we explore the usefulness of nonparametric methods in the investigation of production behavior and the estimation of price elasticities of output supply and input demand functions the approach can handle the situation where some data points are not consistent with production theory the method is illustrated by estimating supply demand elasticities of outputs and inputs in u s agriculture

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

estimating ex ante cost functions for stochastic technologies this paper revisits the problem of estimating ex ante cost functions previously studied by pope and just in 1996 as well as moschini in 2001 an ex ante cost function that generalizes their ex ante cost functions is introduced and an econometric procedure for estimating a flexible approximation to it is developed that generalized cost function is economically relevant not only for the pope and just 1996 choice setting but for general producer risk preferences general stochastic technologies and general forms of price uncertainty an econometric strategy for estimating the resulting cost structure that adapts moschini s 2001 full information approach is developed followed by an econometric application to u s agriculture

endogenous regional agricultural production technologies technical relationships between six productive factors for ten agricultural produvction regions in the continental united states are examined the applied methodology provides a departure from conventional production methodologies contained in the literature by allowing aggregate technical relationships to be endogenized within the economic system

nonparametric tests for monopsonistic market power exertion measurement of market power exerted in imperfectly competitive markets has received considerable attention in recent years this literature has become known as the new empirical industrial organization neio bresnahan 1989 provides an extensive review of these studies most often empirical work relies on estimating monopoly market power exertion from first order profit maximization conditions using aggregate industry data estimates of market power exertion depend on the functional forms selected for aggregate supply and demand importantly econometric identification of the market power parameter estimated from the first order conditions depends critically on second order curvature properties of the functions selected bresnahan 1982 lau little is known about the effects of model misspecification on estimated market power parameters while most of the neio market power literature focuses on monopoly power it is likely that firms with potential market power in agricultural and natural resource markets more of

farm level nonparametric analysis of cost minimization and profit maximization behavior abstract this study investigates non parametrically the optimizing behavior of a sample of 289 kansas farms under profit maximization and cost minimization hypotheses the study uses both deterministic and stochastic non parametric tests the deterministic results do not support strict adherence to either optimization hypothesis the stochastic tests suggest that all 289 farms fail the profit maximization hypothesis whereas 171 farms failed the cost minimization hypothesis allowing for non regressive technical change does not alter the basic results 276 farms violate the profit maximization hypothesis and 138 violate the cost minimization hypothesis the evidence against cost minimization behavior seems to be far less substantial than that against profit maximization behavior

duality theory for variable costs in joint production duality methods for incomplete systems of consumer demand equations are adapted to the dual structure of variable cost functions in joint production this allows identification of necessary and sufficient restrictions on technology and cost so that con ditional factor demands can be written as functions of input prices fixed inputs and cost these are observable when variable inputs are chosen and committed to production hence the identified restrictions allow ex ante conditional demands to be studied using observable data this class of production technologies is consistent with all von neu mann morgenstern utility functions when ex post production and or output prices are un certain

variations on invariance or some unpleasant nonparametric arithmetic the nonparametric approach to production or demand analysis involves testing data for compatibility with restrictions from theory this avoids reliance on particular functional forms when the data are not consistent with utility or profit maximization adjustments in the data using linear programming can restore consistency such adjustments have been interpreted as taste changes or measures of technical change and technical change bias this paper describes nonparametric approaches and shows that the programming methods that have been used yield results that are not invariant to the scaling of prices and quantities a solution is proposed that solves the invariance problem

nonparametric tests of cost minimizing behavior a study of indian farms we extend existing nonparametric methods of analyzing production efficiency to allow some inputs to be quasi fixed varian s weak axiom of cost minimization is modified to derive the weak axiom of variable cost minimization the methodology is applied to farm level data from west bengal india which are analyzed for consistency with cost minimizing behavior there is strong evidence against overall cost minimization a result that cannot be rationalized in terms of production uncertainty and risk aversion however violation of either technical efficiency or of variable cost minimization is much less serious this suggests that failure of cost minimization is principally due to imperfections in the markets for capital and land

impacts of federal crop insurance on land use and environmental quality this article integrates economic and biophysical models to assess how federal crop revenue insurance programs affect land use cropping systems and environmental quality in the u s corn belt region the empirical framework includes econometric models that predict land conversion and crop choices at the parcel level based on expectation and variance of crop revenues land quality climate conditions and physical characteristics at each site the predictions are then combined with site specific environmental production functions to determine the effect of revenue insurance on nitrate runoff and leaching soil water and wind erosion and carbon sequestration results suggest that federal crop insurance has on average a small effect on conversions of non cropland to cropland and somewhat more significant impacts on crop choice and crop rotation these changes in cropping systems have on average small impacts on agricultural pollution

the impact of site characteristics on housing cost estimates abstract hedonic housing regressions using micro data for owners and renters from the 1972 1973 consumer expenditure survey are presented by including tract characteristics and public goods in these regressions evidence is presented which indicates sensitivity of the physical housing variable coefficients to the choice of included site related characteristics furthermore omission of public good variables can result in misleading and possibly perverse coefficients on access intermetropolitan housing cost estimates however are shown to be relatively insensitive to the choice of site related characteristics

supply demand and technology in a multiproduct industry texas field crops the purpose of this paper is to examine the structure of agricultural production for six texas field crops cotton grain sorghum wheat corn rice and hay which account for nearly 95 of recent field crop value specific objectives are to a test the structure of technology to determine i if output and input utilization choices for individual products are independent of production decisions about other outputs and ii if products and or inputs can be consistently aggregated b estimate a coherent set of interrelated supply functions for the six commodities and input demand functions for fertilizer and hired labor because the empirical focus of this paper is specific to one state the results will be of limited value for interpreting specific production relationships elsewhere however the problem is of common interest in production agriculture and the techniques used demonstrate an important application of dual modeling

the effects of suburbanization on agriculture this article conceptualizes the effects of suburban population density and land speculation on agricultural production choices prices and profits a dual profit function model and a system of reduced form price equations are used to estimate these effects for new jersey results show that vegetable production is the only subsector to benefit from suburbanization while livestock is the most adversely affected suburbanization reduces responsiveness to agricultural prices and discourages capital and land use the overall impact on profits is positive when capital gains on land are included policy implications for farmland preservation and right to farm legislation are discussed

estimating irrigator ability to pay for reclamation water the reclamation program sets prices based on irrigators ability to pay for water in contrast to the traditional approach the farm budget study this research develops a model of irrigator profit and ability to pay the shadow price marginal revenue of water is shown to measure ability to pay per acre foot of water the model can be estimated econometrically with commonly available although deficient data using data from thirteen water districts in california annual district level shadow price functions are derived for 1981 91 and compared to ability to pay estimates from a farm budget study of the districts

simple econometrics of pesticide productivity this paper develops a multioutput generalization of the lichtenberg zilberman damage control technology the dual representation of the technology is shown to be conditionally additive in the price of abatement activities and other prices an econometric procedure for estimating the dual technology is developed and applied to an aggregate u s agricultural data set the conditionally additive nature of the model allows estimation of pest damage from the dual technology our estimates of aggregate u s pest damage are much lower than previous estimates

domestic price distortions and agricultural income in developing countries abstract the static effects on agricultural crop production and income arising from the correction of three common policy biases in developing countries the underpricing of food agricultural export taxation and currency overvaluation are examined analytically and empirically using philippine data based on a model of the agricultural sector with the food export crop tradeoff in production as a key component the findings argue for a careful examination of the relative efficiencies of different liberalization policy instruments in advancing specific development objectives in cases where possibly for socio political reasons not all price distortions in interrelated markets can be corrected

a nonparametric analysis of the influence of research on agricultural productivity nonparametric productivity analysis is extended by modeling technical progress as a function of public and private research expenditures results indicate that 30 year lags are required to fully capture the effects of public research expenditures on u s agricultural productivity compared to public research private research has a stronger influence on farm productivity in the short term but a smaller influence in the longer term the internal rate of return is 0 28 for public research and 0 17 for private research

testing for consistent aggregation this paper designs workable empirical procedures for testing or imposing supply demand price aggregators only single equation methods are considered to shift the focus from any particular optimizing paradigm toward the necessities for correctly tabulating firm level supplies demands and aggregate supply demand both macro and micro level tests for consistent aggregation are developed and constructive rules for aggregation based upon empirically observed micro behavior are provided in tabular form empirical tests reveal no support for the aggregate price most commonly reported by usda the constructive rules are then used to develop a new wheat price index consistent with supply aggregation

success in maximizing profits and reasons for profit deviation on dairy farms the weak axiom of profit maximization wapm was used to test how successful each of 70 individual new york state dairy farms was in maximizing profits using nine years of data the netput vectors were corrected for technological change using nonparametric indices that do not require the assumption of profit maximization nor any functional form for the underlying technology these technology indices are consistent with the nonparametric assumptions used in the wapm tests the average negative wapm deviation over the 70 farms was 0 20 indicating that on average these farms could have selected available netput vectors that would have increased profits by 20 of total receipts a tobit regression showed that the available characteristics on these farms explained very little of the variability in their abilities to select the best netput vectors yet increased age and additional education increased the ability to select the best netput vector

rents have been rising not falling in the postwar period abstract until the end of 1977 the u s consumer price index cpi for rents tended to omit rent increases when units had a change of tenants or were vacant biasing inflation estimates downward beginning in 1978 the bureau of labor statistics bls implemented a series of methodological changes that reduced this nonresponse bias but substantial bias remained until 1985 we set up a model of nonresponse bias parameterize it and test it using bls microdata from 1940 to 1985 the official bls cpi for urban wage earners and clerical workers cpi w price index for tenant rents rose 3 6 annually we argue that it should have risen 5 0 annually

multiple input multiple output production choices and technology in the u s wheat region duality theory motivates a translog expected profit function consistent with multiple products price uncertainty preseason climate constraints acreage control policies and possibly nonhomothetic technology although multiple outputs are allowed enterprise specific data is not necessary instead time series measures of output revenues and expected prices input expenses and prices and fixed input flows are employed appropriate measures of elasticities of choice returns to size and biases in technological change are derived results indicated decreasing returns to size rather limited though complementary responsiveness of choices to price changes and the nature of biases in technological changes

production economics worthwhile investment abstract agricultural production economics research is examined within a broad framework of scientific development and utilization recent findings in selected areas of the subdiscipline are examined and opportunities for further fruitful inquiry are identified a few stylized facts emerge from recent work and suggest the need for much careful hypothesis testing model exploration and empirical sensitivity analysis in the future

conflicts between theory and practice in production economics nomic relationships allows multiple theoretical models to explain essentially the same behavior at the same time indirect measurement places great demands on data to test theory for example using parametric tests for profit maximization requires estimating second order curvature parameters to ascertain whether parameters exhibit certain properties it may be difficult to determine second order substitution effects using related price data which in practice are often highly collinear as technical demands placed on data for testing underlying theory increase conflicts between theory and empirical evidence should also be expected to rise

the structure of u s agricultural technology 1910 78 this paper utilizes 1910 78 time series data and a single product aggregate translog profit function to measure the structure of u s agricultural technology duality relations are used to devise a multifactor measure of biased technical change a measure of nonhomotheticity is introduced which indicates the effects scale change has had on aggregate cost shares the empirical analysis finds that different nonhomothetic technologies characterized the prewar and postwar periods differing technical change biases are consistent with relative price trends during the two periods showing that the long run structure of u s agricultural technology has been consistent with the hayami ruttan induced innovation theory

a nonparametric analysis of agricultural technology u s agricultural technology and technical change are analyzed nonparametrically under cost minimization and profit maximization based on annual data for 1948 83 various separability hypotheses concerning the aggregate production function for u s agriculture are investigated the proposed nonparametric approach also provides some insights into the nature of technical change

coordination of fiscal policies in a world economy abstract this paper provides a simple counterexample to the standard belief that in a world economy in which all countries are small strategic interactions between policymarkers are trivial and thus cooperative and non cooperative government policies coincide it is well known that this holds for tariff policies however this paper demonstrates the result does not apply to fiscal policy in addition the paper analyzes how optimally coordinated fiscal policies differ from non cooperative policies it finds that relative to optimally coordinated levels non cooperative government spending can be too high or too low depending on the sign of a transmission effect which captures the overall effect countries actions have on each other

the gains from fiscal cooperation in the two commodity real trade model abstract this paper analyzes the gains from fiscal cooperation within the context of the standard two commodity real trade model it shows how the adjustment in the terms of trade is the critical factor in determining the effects of moving from a noncooperative equilibrium in general a noncooperative equilibrium leads to an overexpansion of government expenditure on the import good relative to a cooperative equilibrium the specific example of a logarithmic economy is also considered the paper discusses further the welfare effects resulting from the formation of a coalition of two countries among three

environmental externalities and the optimal level of market power this article derives the condition under which agricultural chemical producers desire to under produce associated with market power exactly offsets the tendency to overproduce due to their failure to consider externality costs of agricultural chemicals this condition is satisfied when the price markup in the chemical industries equals the marginal environmental damages caused by chemicals our estimates of price markup for nitrogen phosphate and pesticides industries indicate that the welfare loss caused by market power is exactly offset by environmental benefits if the marginal pollution costs are respectively eight nine and twenty two cents for each dollar s worth of these chemicals

environmental productivity and kuznets curve in india abstract as a result of india s extremely rapid economic growth the scale and seriousness of environmental problems are no longer in doubt whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies in this study we use state level industry data of sulfur dioxide nitrogen dioxide and suspended particular matter over the period 1991 2003 employing recently developed productivity measurement technique we show that overall environmental productivities decrease over time in india furthermore we analyze the determinants of environmental productivities and find environmental kuznets curve type relationship existences between environmental productivity and income panel analysis results show that the scale effect dominates over the technique effect therefore a combined effect of income on environmental productivity is negative
