environmental regulation and u s economic growth in this article we quantify the costs of pollution controls by reporting the results of simulations of the growth of the u s economy with and without regulation for this purpose we have constructed a detailed model of the economy that includes the determinants of long term growth we have also analyzed the interaction between industries in order to capture the full repercussions of environmental regulations however we have not attempted to assess the benefits resulting from a cleaner environment we find that pollution abatement has emerged as a major claimant on the resources of the u s economy the cost of emission controls is more than 10 of the total cost of government purchases of goods and services

the role of air and water residuals for steam electric power generation the decade of the sixties saw increasing concern over the progressive deterioration in environmental quality and in the early seventies major federal legislation established air and water pollution control strategies at the time these laws were enacted information on the costs and benefits of pollution control programs was limited today nearly two decades after the first expressions of concern there remain few neoclassical models of productions that explicitly incorporate residuals as by products of production activities most of the available information on the costs of pollution control policies is based on engineering cost analyses of model plants as a rule these studies estimate costs by considering the increments to production costs associated with adding specific types of capital equipment to reduce emissions to specified levels they often do not consider the full menu of responses possible in meeting a given emission standard equally important they are relevant only for the model plant which formed the basis for the cost calculations the purpose of this paper is to present the results of a neoclassical analysis of the role of a variety of residuals that generally comprise the major air and water emissions of steam generating electric plants our analysis distinguishes plants by vintage of equipment and treats generating capital as a quasi fixed factor thus the results provide a description of the features of the ex post production technology it should of course be acknowledged that a neoclassical production model is an approximate summary of the engineering features of the underlying technology the value of the approach to describing production activities ultimately depends on its ability to authentically describe the features of that technology recent experimental evidence by kopp and smith 25 suggests that neoclassical cost models which ignore constraints on industrial effluents may provide seriously misleading descriptions of the features of the underlying production processes steam electric generating

environmental efficiency measurement and the materials balance condition reconsidered abstract this note takes up a shortcoming of coelli et al s 2007 popular environmental efficiency measure and its extension to economic environmental trade off analysis see van meensel et al 2010 namely that they do not reward emission reductions by pollution control a new environmental efficiency measure that overcomes this issue and similar to coelli et al s efficiency measure is in line with the materials balance principle is proposed and further decomposed into technical environmental efficiency and material and nonmaterial allocative environmental efficiencies the new efficiency measure collapses into coelli et al s efficiency measure if none of the considered decision making units control pollutants a numerical example using data envelopment analysis is provided to further explore the properties of the new efficiency measure

examining the hayek friedman hypothesis on economic and political freedom abstract this paper examines empirically the hypothesis made famous by nobel laureates friedrich a hayek and milton friedman that societies with high levels of political freedom must also have high levels of economic freedom in our judgment the hayek friedman hypothesis holds up fairly well to historical scrutiny using data on economic and political freedom for a sample of up to 123 nations back as far as 1970 we find relatively few instances of societies combining relatively high political freedom without relatively high levels of economic freedom in addition we find that these cases are diminishing over time finally we examine several cases of countries on different economic and political freedom journeys

the short run impact of environmental protection costs on u s product prices using an input output framework this paper investigates the magnitude of the impact that environmental protection costs had on prices in the united states in 1977 with the imposition of environmental protection costs the projected total price increases for individual industries range from 0 12 to 6 58 due to data limitations the constraints of input output analysis and the structural changes that occurred in the economy from 1972 to 1977 the results should not be taken as definitive however the results do indicate the typical sort of variation in impact likely to occur across industries and that the average impact on prices was modest

the two freedoms economic growth and development an empirical study log linear methods are applied to categorical data containing economic freedom political freedom the level of income and the rate of economic growth for a panel of about 100 countries from 1975 to 1992 the main results are given economic freedom the rate of economic growth is independent of political freedom and the level of income given the level of income political freedom is independent of economic freedom and the growth rate the analysis suggests the fundamental effects of economic freedom in fostering economic growth and a high level of income as the condition of a high degree of political freedom

plant vintage technology and environmental regulation abstract we use data on productivity and pollution abatement costs at individual pulp and paper mills to test whether the impact of environmental regulation on productivity differs by plant vintage and technology plants with higher pollution abatement costs have significantly lower productivity levels this relationship differs greatly based on a plant s technology with productivity at integrated mills being greatly affected by abatement costs while the impact at non integrated mills is negligible plant vintage does not seem to matter with older and newer plants showing similar impacts reported abatement costs appear to substantially understate the true costs of abatement accounting for the impact of technology differences makes some difference in the estimated overall impact of environmental regulation

can a carbon trading system promote the transformation of a low carbon economy under the framework of the porter hypothesis empirical analysis based on the psm did method abstract global warming is one of the issues of great concern in the world the large scale use of fossil fuels has led to the continuous increase in carbon emissions resulting in global energy shortages and environmental pollution reasonable and strict environmental regulation promotes technological innovation by enterprises to achieve a win win situation between the economy and environment which is the core idea of the porter hypothesis the choice of china as the world s largest energy consumer and carbon emitter is not only related to the country s own mode of economic growth but also determines the development of the world s low carbon economy we used the panel data from 2000 to 2016 of 30 provincial level administrative regions in china and adopted the propensity score matching difference in differences method to test the impact of china s carbon trading pilot system on the transformation of a low carbon economy the empirical results show that under the constraints of the established resources and environment there is a positive relationship to some extent between china s carbon trading system and low carbon economic transformation this relationship can realize the win win situation of environmental and economic benefits as advocated by the porter hypothesis and further verify the applicability of the porter hypothesis

cost functions and nonlinear prices estimating a technology with quality differentiated inputs the paper is concerned with developing a production theory for the case when some inputs have nonlinear prices because the price depends on endogenous quality this involves extending the notion of a cost function to the case where nonlinear prices are parameters of costs after developing the appropriate theory we apply our results to the case of coal fired electric power generation where fuel quality depends on sulfur and ash impurities environmental regulations induce a negative value on sulfur whereas ash impurities degrade performance and thus reduce production possibilities a number of empirical results emerge including significant rates of technological change that are sulfur and ash saving though capital using this change may explain in part the recent drop in the price of sulfur allowances in the united states

environmental efficiency with multiple environmentally detrimental variables estimated with sfa and dea abstract the objective of this paper is to estimate comprehensive environmental efficiency measures for dutch dairy farms the environmental efficiency scores are based on the nitrogen surplus phosphate surplus and the total direct and indirect energy use of an unbalanced panel of dairy farms we define environmental efficiency as the ratio of minimum feasible to observed use of multiple environmentally detrimental inputs conditional on observed levels of output and the conventional inputs we compare two methods for the calculation of efficiency namely stochastic frontier analysis sfa and data envelopment analysis dea this paper reveals the strengths and weaknesses for estimating environmental efficiency of the methods applied both sfa and dea can estimate environmental efficiency scores the mean technical efficiency scores output oriented sfa 89 dea 78 and the mean comprehensive environmental efficiency scores sfa 80 dea 52 differ between the two methods sfa allows hypothesis testing and the monotonicity hypothesis is rejected for the specification including phosphate surplus dea can calculate environmental efficiency scores for all specifications because regularity is imposed in this method

environmental regulation and competitiveness empirical evidence on the porter hypothesis from european manufacturing sectors abstract this paper investigates the weak and strong versions of porter hypothesis ph focusing on the manufacturing sectors of 17 european countries between 1997 and 2009 the hypothesis that well crafted and well enforced regulation would benefit both the environment and the firm was originally proposed by porter 1991 and porter and van der linde 1995 to date the literature has analyzed the impact of environmental regulation on innovation and on productivity mostly in separate analyses and focusing on the usa the few existing contributions on europe study the effect of environmental regulation either on green innovation or on performance indicators such as exports we instead look at overall innovation and productivity impacts first focusing on overall innovative activity allows us to account for potential opportunity costs of induced innovations second productivity impacts are arguably the most relevant indicators for the strong ph as a proxy of environmental policy stringency we use pollution abatement and control expenditures pace one of the few sectoral level indicators available we remedy upon its main drawback namely potential endogeneity by adopting an instrumental variable estimation approach we find evidence of a positive impact of environmental regulation on the output of innovation activity as proxied by patents thus providing support in favor of the weak ph this result is in line with most of the literature on the other front we find no evidence in favor of the strong ph as productivity appears to be unaffected by the degree of pollution control and abatement efforts

capacity utilization in a generalized malmquist index including environmental factors a decomposition analysis productivity measures ignoring environmental effects may give misleading information on total productivity growth further business cycles in the form of capacity utilization may significantly influence productivity measures we develop an overall malmquist productivity index and decompose changing efficiency rates into a contribution from environmental factors capital and capacity utilization our new combined capacity utilization element contributes to the literature in that it also takes into account the restriction for producing negative externalities empirical applications illustrate that the choice of inputs influences the overall productivity measure and its decomposition into efficiency changes and technical changes and the capacity utilization element

multilateral productivity comparisons with undesirable outputs in a recent paper in this journal caves christensen and diewert i982 hereafter ccd derive what they term multilateral superlative indexes for use in the comparison of output input and productivity across economic entities the indexes derived are distinguished both by transitivity and by a high degree of characteristicity a term introduced by dreschler i 973 to refer to the degree to which the weights used in a comparison are specific to the observations being compared though the indexes are presented with the application to multicountry comparisons of output input and productivity foremost in mind the authors note that they may be useful in a number of other contexts as well i e firms and industries time series and pooled time series and cross section all of the applications mentioned or implied however have this in common they involve the comparison of productive entities all of whose outputs are sold for positive prices this is not surprising of course since most products with which economists are concerned possess this characteristic however it does render incomplete or potentially misleading the comparison of productive entities which produce significant amounts of undesirable outputs such as water and air pollution since the list of such entities is rather long and includes industries critical to many national and regional economies e g chemicals paper petroleum refining copper and steel the omission of this factor from consideration may be a matter of some importance 2 consider for example a comparison of the productivity of the steel industries

the economic costs of environmental regulation in u s dairy farming a directional distance function approach analyses of the costs of regulating greenhouse gas emissions from dairy production which could be used to assess the effectiveness of alternative policy measures is a missing link in the literature this article addresses this gap by establishing the economic impact associated with a hypothetical greenhouse gas environmental regulatory regime across major dairy producing counties in the united states in doing so the article makes three important contributions to the literature first it develops a comprehensive pollution index based on environmental protection agency methodologies which contrasts with previous studies that rely on partial measures based only on surplus nitrogen stemming from the over application of fertilizer second the article uses a directional output distance function an approach that has not been employed previously to evaluate polluting technologies in the u s dairy sector third the article incorporates a four way error approach that accounts for unobserved county heterogeneity time invariant persistent technical efficiency time varying transient technical efficiency and a random error the results indicate that regulating greenhouse gas emissions from dairy farming would induce a 5 percentage point increase in average technical efficiency in addition the economic costs of implementing this hypothetical regulatory framework exhibit significant spatial variation across counties in the united states

a new approach to measuring shadow price reconciling engineering and economic perspectives abstract shadow price is one of the most important pieces of information in environmental decision making two different approaches namely economic and engineering have been applied to obtain the shadow price of undesirable outputs while using different methodological backgrounds and perspectives the current study proposes a new conceptual framework and an economic estimation model to reconcile the shadow price estimates derived via the two approaches we also suggest a new mapping rule that incorporates the concept of abatement level which is a basic element in the engineering approach as a result the proposed model generates continuously changing estimates i e comprising a shadow price curve based on the abatement level we further investigate the determinant factors of shadow price by using second step regression the suggested methodology is used to investigate the shadow price of carbon emissions in south korean electricity generating plants thus yielding relevant policy implications

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

the impacts of the clean air act on production cost and the substitution between inputs in the electric utility industry abstract the paper examines how having to comply with phase 1 of title iv of the 1990 clean air act affected production cost and the substitution between fuel and non fuel labor capital inputs phase 1 required firms to reduce their sulfur dioxide emissions enacting procedures to reduce sulfur dioxide emissions using lower sulfur content coal or other fuel sources could lead to higher cost and impact the substitution between fuel and non fuel inputs using a 1992 2000 panel of 34 u s electric utilities empirical results indicate that the procedures electric utilities enacted to comply with phase 1 contributed to small increases in both marginal cost and total cost firms having to comply with phase 1 were more willing than firms not subject to phase 1 to substitute from fuel to non fuel labor capital inputs following an increase in the price of fuel utilities subject to phase 1 that had a fuel clause were more willing than phase 1 firms without a fuel clause to substitute from non fuel inputs to fuel when the price of the non fuel input increased

extending the economic theory of regulation to the form of policy the mutually beneficial connection between industries and the governments that regulate them is the subject of a large literature led by stigler 1971 what has not been studied is how firms choose their desired policies from the set including entry barriers price floors subsidies and demand stimulation we take as given that government and incumbents from the supply and demand for regulation and explore the choice of political product

natural versus manufactured capital win lose or win win a case study of the finnish pulp and paper industry abstract the effect of investments on environmental variables has been discussed through the win win rhetoric specifically in micro level analysis on the macro level the win win rhetoric has been replaced by the arguments for and against the substitutability of natural and manufactured capital here these two concepts belonging to different levels of analysis are linked by looking at the environmental and economic effects of chosen investment strategies in a traditionally capital intensive industry over time the paper shows that rather than generalise the existence of win win situations or the substitutability of capital these positions are determined by purely situational factors as a result in the assessment of substitutability the specific operating context of the industry needs to be taken into account this implies also that environmental policy needs to be designed to be adaptive and responsive to those situational factors to create beneficial outcomes for the economy and for the environment

technological change and welfare in an open economy with distortions traditional measures of technological change such as the rate of technical change are based on producer oriented prices consumer oriented welfare measures such as the hicksian variations are more appropriate measures of the ultimate benefits of technology but they require knowledge of consumer valuations of outputs and inputs and the price impacts of the technological change the general equilibrium analysis here evaluates these price impacts and shows how the welfare gain from technological change can be decomposed into the rate of technical change plus an induced price change effect plus the effect of any ad valorem price distortions that exist in the economy the graphic interpretation of these welfare effects suggests alternatives to the usual partial equilibrium social surplus measures of the gains from technological change

the impact of pollution abatement investment on productivity change anempirical comparison of the u s germany and canada since environmental quality became an important focus of government regulations in most industrialized countries in the early 1970s many researchers have assessed the impact of these regulations on economic performance for example leontief and ford 11 and pasurka 15 investigated the impact that environmental protection costs had on prices in the u s walter 24 calculated the effect of pollution abatement expenditures on u s trade and robinson 19 measured the distributional impact of the burden of industrial pollution abatement a related issue involves the productivity consequences of environmental regulations in this paper we address this issue by considering the impact of pollution abatement investment on productivity growth

competition among hospitals we examine competition in the hospital industry in particular the effect of ownership type for profit not for profit government we estimate a structural model of demand and pricing in the hospital industry in california then use the estimates to simulate the effect of a merger california hospitals in 1995 face an average price elasticity of demand of 4 85 not for profit hospitals face less elastic demand and act as if they have lower marginal costs their prices are lower than those of for profits but markups are higher we simulate the effects of the 1997 merger of two hospital chains in san luis obispo county where the merger creates a near monopoly prices rise by up to 53 and the predicted price increase would not be substantially smaller were the chains not for profit

the contribution of environmental regulations to the slowdown in productivity growth abstract the radical slowdown in productivity growth since 1965 is often attributed to environmental regulations several studies varying widely in method have attempted to assess this contribution here these analyses are reviewed and critiqued and a summary appraisal of the likely contribution of environmental regulations to the observed decrease in productivity growth is offered

economic freedom democracy and the quality of life summary many empirical studies indicate that economic freedom in society is positively correlated with prosperity and growth while democracy exhibits mixed correlations however these studies do not control for the possible interaction of these two types of freedoms or their respective influences on social welfare this empirical analysis examines the interaction of economic freedom and democracy on measures of health education and disease prevention in society the results imply that greater economic freedom consistently enhances these welfare measures even among more democratic countries democracy has a smaller positive influence that disappears for many welfare measures in countries with more economic freedoms

environmentally sensitive productivity growth a global analysis using malmquist luenberger index abstract we examine conventional and environmentally sensitive total factor productivity tfp in 41 developed and developing countries over the period of 1971 to 1992 due to the non availability of reliable input and co 2 emissions price data the study uses directional distance function to derive malmquist luenberger ml productivity index the index allows us to decompose the tfp into measures of technical and efficiency changes dea is used to compute the directional distance functions we find that tfp index value is not different when we account for the co 2 emissions relative to the situation when they are freely disposable but for the components of tfp change technical and efficiency changes the null hypothesis of whether the indexes are the same under two different scenarios cannot be accepted issues of catch up and convergence or in some cases possible divergence in productivity are examined within a global framework the paper also studies the impact of openness on conventional and environmentally sensitive measures of productivity

export performance and productivity growth the case of taiwan the hypothesis that rapid growth of exports accelerates economic growth has been widely discussed and tested the empirical evidence that supports the hypothesis includes studies by m michaely b balassa p heller and r porter w tyler g feder r kavoussi and r ram using macrodata and m nishimizu and s robinson using two digit industry level data feder found that exports contribute to economic growth because the export sector is not only more productive than the nonexport sector but also generates some external effects that enhance the productivity of the nonexport sector as exports expand both the resource reallocation effect and externality effect lead to an economy wide productivity increase nishimizu and robinson also found the existence of a significant correlation between productivity growth and export expansion on a theoretical level there are at least two interpretations of the correlation between productivity growth and export expansion one stresses scale economies the other stresses competitive forces the scale economies argument emphasizes the benefits that can be derived by means of expanding the scale of operations in the case of countries whose domestic markets are small in size exporting becomes an essential part of achieving scale economies j bhagwati considered scale economies to be a plausible explanation for the superiority of the export promotion trade strategy as opposed to the import substitution trade strategy but warned against the lack of convincing evidence 2 the study by j kwon on the korean manufacturing industry also found that scale economies are a main factor contributing to total fac

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

separating the influence of capitalism and democracy on women s well being abstract this empirical analysis seeks to determine which institutional arrangement capitalism or democracy tends to be more effective at improving women s well being and promoting gender equality in society country specific indexes measuring the degree of economic freedoms that exist within the market and the degree of political rights that exist within a democracy are used in a panel data analysis to explain the observed levels of various quality of life measures reflecting issues that are relevant to women these empirical results indicate that capitalism often has a stronger beneficial impact on many aspects of women s well being and gender equality in society

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

health insurance eligibility utilization of medical care and child health two economists applied data from the current population survey and the national health interview survey and state level data on child mortality to a simulation model of utilization of medical care that varies only with the states legislative environment to examine the utilization of medical care and health effects of medicaid eligibility on low income children the models took into consideration the recent expansions of medicaid to low income children 38 of those ineligible for medicaid in 1984 who became eligible due to changes during 1984 1992 were uninsured between 1984 and 1992 expansions of the medicaid program increased the proportion of children eligible for medicaid almost two fold 16 1 vs 31 2 yet coverage rates were always lower than eligibility rates 13 2 vs 16 1 in 1984 and 20 3 vs 31 2 in 1992 and the increase in coverage rates was only about 50 of the increase in eligibility rates during 1984 1992 the probability that a child was eligible for medicaid increased the probability of health insurance coverage by 29 77 when the model considered bias in variables e g a recession in a state the take up rate was only 22 73 nevertheless medicaid markedly increased use of medical care for example eligibility for medicaid increased the likelihood of making a visit to a physicians office in the last two weeks by about 50 it also increased the probability of a child visiting the hospital suggesting inefficiency in the way that providers deliver care to medicaid enrollees medicaid eligibility had a significant effect on reducing child mortality the 15 1 percentage point increase in eligibility during 1984 1992 reduced child mortality by 4 5 when the researchers examined parent assessed subjective health measures medicaid eligibility had no effect on child health medicaid eligibility reduced race and education based disparities in the number of visits and racial differences in mortality yet it may actually intensify current disparities in health care delivery site

the impact of regulatory reforms on cost structure ownership and competition in indian banking this paper evaluates the impact of financial sector reforms on the cost structure characteristics and on the ownership cost efficiency relationship in indian banking it also examines the impact of reforms on the dynamics of competition in the lending market we find evidence that deregulation improves banks performance and fosters competition in the lending market results suggest technological progress once indian commercial banks have adjusted to the new regulatory environment this however does not translate in efficiency gains there is also evidence of an ownership effect on the level and pattern of efficiency change finally competition keeps building pace even in the re regulation period and technological improvements are not hampered by the tightening of prudential norms

who pays for industrial pollution abatement the distributional impact of industrial pollution abatement is measured for the years 1973 and 1977 the findings indicate that in 1977 1 09 of income or 0 510 of personal consumption expenditures of the lowest income class paid indirectly for abatement costs implicit in purchased goods for the highest income class the corresponding figures were 0 218 and 0 423 respectively in addition abatement costs per dollar of output are presented for representative industries

productivity growth and environmental regulation in mexican and u s food manufacturing many argued during the nafta debate that trade liberalization would favor mexican over u s food processors especially because of lax environmental laws south of the border we find through an examination of profit functions that productivity growth in mexico has outstripped that in the united states suggesting free trade indeed will benefit mexican suppliers u s pollution regulations have had no impact on the profitability or productivity of u s food manufacturing in contrast mexico s swiftly rising environmental standards have enhanced food processors productivity growth corroborating the porter hypothesis pollution law therefore has favored mexican over u s food processing but for reasons few had anticipated

marginal abatement costs of carbon dioxide emissions and its influencing factors a global perspective abstract reducing co 2 emissions has become a major and urgent environmental goal worldwide in this paper we sample the data of 41 regions including 165 countries from 2000 to 2014 and adopt a gravity model to obtain an overview of the global flows of co 2 emissions energy consumption the global economy and capital stock since the beginning of the 21st century we then investigate global technical efficiency reduction potential shadow prices and factors influencing the marginal abatement costs of co 2 emissions based on a quadratic directional output distance function the empirical results show the following 1 the global centres of gravity for co 2 emissions energy consumption and capital stock have accelerated their shift to the asian inland in the 21st century but the global centre of gravity for the economy did not show the same trend 2 global technical inefficiency demonstrates a u shape with a turning point in 2007 average annual total global co 2 emissions could be reduced by 4482 28 mt and the global marginal abatement costs of co 2 emissions are approximately 673 74 697 73 usd t 3 the relationship between economic development and marginal abatement costs is represented by a u shaped curve the world is currently in the climbing phase of this curve implying that controlling co 2 emissions is becoming more costly moreover energy structure industrial structure and co 2 emissions are negatively correlated with marginal abatement costs finally the financial crisis has had a significant effect on marginal abatement costs

environmental innovations and profitability how does it pay to be green an empirical analysis on the german innovation survey much of the empirical literature analysing the relation between environmental innovation and competitiveness has focused on the question whether it pays to be green we differentiate between different types of environmental innovations which will be disentangled in those aiming at reducing the negative externalities and those allowing for efficiency increases and cost savings what we analyze is at first the extent to which these two typologies have impacts on firms profitability with opposite signs and secondly whether the motivations driving the adoption of those innovations make the difference in terms of economic gains we find empirical evidence that both the typology of environmental innovation and the driver of their adoption affect the sign of the relationship between competitiveness and environmental performance the empirical strategy is based on a sample of german firms and makes use of a merge of two waves of the mannheim innovation panel in 2011 and 2009 that allow overcoming some endogeneity issues which may arise in a cross section setting

institutions investment and growth new cross country and panel data evidence this paper outlines the alternative channels through which institutions affect growth and studies the empirical relationship between institutions investment and growth the empirical results indicate that i free market institutions have a positive effect on growth ii economic freedom affects growth through both a direct effect on total factor productivity and an indirect effect on investment iii political and civil liberties may stimulate investment iv an important interaction exists between freedom and human capital investment v milton friedman s conjectures on the relation between political and economic freedom are correct vi promoting economic freedom is an effective policy toward facilitating growth and other types of freedom jel o17 o40 p51

hayek samuelson and the logic of the mixed economy abstract in 1980 friedrich hayek wrote to paul samuelson complaining about the role that economics had played in discrediting the thesis of hayek s the road to serfdom in the 11th edition of economics samuelson had written that each step away from the market system and towards the social reform of the welfare state is inevitably a journey that must end in a totalitarian state given the apparent prevalence of this reading of hayek s thesis we assess the dispute over hayek s inevitability thesis and whether hayek s complaints were justified

incentivizing better quality of care the role of medicaid and competition in the nursing home industry this paper develops a model of the nursing home industry to investigate the quality effects of policies that either raise regulated reimbursement rates or increase local competition using data from pennsylvania i estimate the parameters of the model the findings indicate that nursing homes increase the quality of care measured by the number of skilled nurses per resident by 8 7 following a universal 10 increase in medicaid reimbursement rates in contrast i find that pro competitive policies lead to only small increases in skilled nurse staffing ratios suggesting that medicaid increases are more cost effective in raising the quality of care

asymmetric information ownership and quality of care an empirical analysis of nursing homes theoretically when asymmetric information exists nonprofit organizations due to the attenuation of the property right provide better quality of service than do the for profits despite extensive theoretical examination of the behavior of nonprofits there has been very little empirical testing of the plausibility of these theories this article addresses the effect of ownership type on the quality of service in the nursing home industry an environment particularly conducive to identifying the existence of asymmetric information the study shows that the differences between for profit and nonprofit homes do become manifest when asymmetric information is present

pricing by non profit institutions the case of hospital cost shifting abstract this paper shows that a hospital whose objective function includes output as well as profits may raise price to private paying patients in response to cuts in the price it receives for madicaid or medicaid patients evidence is presented to show that hospitals in illinois cost shifted in this manner in response to substantial reductions in medicaid payments in the early 1980s as private sector pricing becomes more competitive however the ability and willingness of hospitals to cost shift will wane

institutions and savings in developing and emerging economies domestic savings are an important prerequisite for capital formation and growth in this paper we analyze a new channel through which institutions influence aggregate savings and economic development whereas research in the field of savings decisions concentrates largely on the level of the individual the literature on institutions and growth as well as on aggregate savings formation focuses on the aggregate national level first we develop a framework that brings together both lines of reasoning arguing that institutions may influence the individual savings decision as well as national savings in aggregate this potential for institutional quality to influence economic performance has been neglected so far second we build upon the empirical literature on aggregate savings formation and provide results supporting our hypothesis that better economic institutions drive aggregate savings formation upwards by contrast we do not find such effects in the case of the political environment our findings are robust when checked against a number of changes in explanatory variables estimation methods and the treatment of instruments

estimating the shadow prices of so2 and nox for u s coal power plants a convex nonparametric least squares approach abstract weak disposability between outputs and pollutants defined as a simultaneous proportional reduction of both outputs and pollutants assumes that pollutants are byproducts of the output generation process and that a firm can freely dispose of both by scaling down production levels leaving some inputs idle based on the production axioms of monotonicity convexity and weak disposability we formulate a convex nonparametric least squares cnls quadratic optimization problem to estimate a frontier production function assuming either a deterministic disturbance term consisting only of inefficiency or a composite disturbance term composed of both inefficiency and noise the suggested methodology extends the stochastic semi nonparametric envelopment of data stoned described in kuosmanen and kortelainen 2011 applying the method to estimate the shadow prices of so 2 and no x generated by u s coal power plants we conclude that the weak disposability stoned method provides more consistent estimates of market prices

measurement of agricultural total factor productivity growth incorporating environmental factors a nutrients balance approach this article proposes to use nutrient orientated environmental efficiency ee measures to construct a nutrient total factor productivity index ntfp since nutrient orientated ee measures are consistent with the materials balance principle ntfp index is superior to other existing tfp indexes an empirical study on the environmental performance of an agricultural sector in 30 oecd countries from 1990 to 2003 yielded several important findings first these countries should be able to produce current outputs with at least 50 less aggregate eutrophying power implying that they should have been able to substantially reduce the potential for eutrophication second traditional tfp has grown by 1 6 per annum due to technical progress however there are lags in the responses of several countries to this technical progress third environmental tfp has grown at a slower rate than traditional tfp growth due to reductions in nutrient orientated allocative efficiency finally changes in input combinations could have significantly improved environmental efficiency and productivity these findings favor policy interventions and faster technological transfer to improve environmental performance

issue in pollution control interplant cost differences and economies of scale debate on interplant pollution control cost differences focuses on the question of whether a system of taxes or transferable discharge permits should require those plants with low treatment costs to control a higher share of effluents another issue under debate is whether those industries with a large minimum size may be effectively barred by pollution control requirements evidence of the inefficiency of present institutional arrangements is shown by studying production function estimations of 30 pulp and paper mills in wisconsin and michigan a more efficient reallocation of pollution control resources could be effected with more market oriented regimes 58 references 6 tables dck

environmental regulation cost and industry structure changes nonstationary markov analyses are used to investigate impacts of environmental regulatory costs associated with compliance on changes in market structure in pulp and paper industries results show environmental regulation expenditures have statistically significant effects on the probabilities of capacity moving to a larger company size category so industry structure is affected by environmental regulation however counter to expectations results further show consolidation occurs with higher probability when environmental costs are falling rather than when they are rising policy analyses that presume immediate policy responses to cost changes or that industry structure is unchanged may yield time inconsistent policy conclusions

differential environmental regulation effects on electric utility capital turnover and emissions this paper tests the hypothesis that differential regulations reduced the rate of capital turnover in the electric utility industry resulting in increased emissions of sulfur dioxide based on a sample of forty four privately owned electric utilities operating over the period 1969 83 the authors results indicate that 1 regulation increased the age of capital by an average of 3 29 years 24 6 percent 2 increases in the age of capital have no statistically significant impact on emissions and 3 in the absence of regulation emissions would have increased by 3 79 tons per million kwhs 34 6 percent copyright 1993 by mit press

environmental regulation and environmental productivity the case of china abstract constrained by the dual mission of supporting industrial growth and reducing emissions china s traditional emission reduction oriented environmental policies unavoidably face a dilemma this study adopts the gml index to calculate china s industrial productivity by considering environmental factors in addition based on the assumption of industry heterogeneity the author examines the non linear relationship between china s environmental regulation and environmental productivity and calculated the optimal regulation environment for industries according to this study when impact of undesirable outputs pollutant emissions is considered environmental regulation and environmental productivity are positively correlated which to some degree validates the porter hypothesis at present environmental regulation has significant positive effects on clean production industries but shows a lag effect on pollution intensive industries the degree of environmental regulation and environmental productivity show an inverted u shaped relation and display three thresholds it should be noted however that the relationship between regulation and productivity may vary across industries these findings have clear policy implications rather than continually increasing the level of environmental regulation the government should establish standards for individual industries that emphasize flexibility

productivity measurement in the presence of poorly priced goods interest in productivity measurement was originally motivated by interest in the effect of additional output on consumers standard of living but traditional productivity studies have focused on the effect of shifts in the production frontier itself rather than changes in welfare there are two reasons for this a the economy s production frontier is a constraint on consumers utility so its expansion is of inherent interest and b if there are no market failures measures of shifts in the production frontier and welfare change coincide this reasoning collapses when market failure causes a divergence between consumers marginal rates of substitution and producers marginal rates of transformation i e when some goods are poorly priced the case of unpriced environmental goods is an obvious case in point there is general concern that if new technology fouls the environment then measures of shift in the production frontier such as total factor productivity tfp cannot really reflect what we want to measure because the value of goods such as clean air or water are not included in the tfp calculations

a nonparametric analysis of variable cost minimization in the united states paper industry nanparametric tests of consistency of data with variable cost minimization returns to scale homotheticity are described and applied to data from the us paper industry results indicate that data from the us paper industry are consistent with the minimization of variable costs increased productivity due to technological improvements or increasing returns to scale and a homothetic production function a method derived from nonparametric estimation for screening hypothesized data sets prior to predictive use with an estimated production function is described

a general index of technical change this paper outlines a procedure for estimating a general index of technical change within the context of a quite general production technology specifically when panel data are available for firms in an industry time specific dummies can be combined in a nonlinear estimation procedure to yield a general index of technical change that may be both nonneutral and scale augmenting this approach offers numerous advantages over the traditional time trend representation of technical change for example the general index can serve as the basis for analysis of the determinants of technical change results for a sample of 30 electric utilities over the period 1951 78 show that the productivity decline of the 1970s can be attributed primarily to sulphur oxide restrictions and secularly declining capacity utilization due to rapidly increasing peak load demands

the market impact and the cost of environmental policy evidence from the swedish green car rebate we quantify the effects of the swedish gcr a program to reduce oil dependence and greenhouse gas emissions in the automobile industry we find the gcr to increase the market shares of green cars and its cost to be 109 tonco2 saved thus 5 times the price of an emission permit since the main green cars in sweden are ffvs flexible fuel vehicles which can switch between petrol gasoline and ethanol we also account for fuel choice which increases the cost of the program finally we show that consumers would have purchased ffvs regardless of the rebate provided by the gcr

pollution abatement and productivity growth evidence from germany japan the netherlands and the united states the passage of environmental legislation was accompanied by concerns about its potential detrimental effect on productivity we assume inputs can be assigned to either abatement activities or good output production this allows us to specify regulated and unregulated production frontiers to determine the association between pollution abatement and productivity growth we then employ our assigned input model to determine the association between productivity and abatement activities for manufacturing industries in germany japan the netherlands and the united states

sources of emission reductions market and policy stringency effects abstract international trade and economic development affect air emissions previous studies have decomposed their effects into scale composition and technique effects while the scale and composition effects occur through market responses the technique effect is a policy stringency influence through the mix of environmental policies this study analyzes whether the market or policy stringency effects are more prominent previous studies have been unable to adequately separate the market and policy stringency effects to independently measure the technique effect we use two indicators of policy stringency i e shadow prices of energy and industrial energy prices these policy stringency measures are treated as endogenous the effects on six types of air emissions are estimated utilizing a sector specific international panel dataset that includes newly industrialized and former transition economies the empirical results show that the major source of emissions reductions is the policy stringency effect through carbon related policies pollution offshoring to countries with weaker carbon related regulation has a minor role in the reduction of air emissions

pricing for the clean air evidence from chinese housing market abstract air pollution is widely believed to cause healthy risks and influence nations economic dimensions this paper investigates the impact of air pollution on housing prices in china s 286 prefectural level cities during 2005 2013 to address the endogeneity problem of pm2 5 concentrations in our regression we propose an instrument variable strategy based on ventilation coefficient the estimation results suggest that a 10 increase in pm2 5 concentrations causes a 2 4 reduction in local housing prices air pollution also hinders the progress of urbanization limits cities human capital formation and changes people s expectations of housing prices that we interpret as three potential mechanisms behind our main findings

capturing the least costly way of reducing pollution a shadow price approach abstract the production analysis literature is increasingly concerned with estimating marginal abatement costs yet most studies do not emphasize the ways in which pollutants may be reduced and their costs which makes them unable to identify the least costly compliance strategy this paper utilizes the materials balance principle to relate pollution to the employment of material inputs a production model which allows input and output substitution downscaling of operations pollution control and emission permits purchases as compliance strategies is proposed and the implications of joint and non joint pollution controls for the trade off between pollutants and desirable outputs are considered marginal abatement costs reflecting the least costly way of compliance are derived by exploiting the duality between the directional distance function and the profit function

environmental regulations and plant exit a qualitative response model is applied to study the relationship between environmental regulations and plant exit the data set is norwegian panel data for establishments in three manufacturing sectors that have high shares of units which have been under strict environmental regulations in two of the sectors the estimated exit probability of regulated establishments is ceteris paribus only one third of the exit probability of non regulated establishments we also find that the probability to change regulation status from being non regulated to become regulated depends significantly on economic factors in particular establishments with weak profitability had the highest probability to come under environmental regulation

productivity measurement in common property resource industries an application to the pacific coast trawl fishery this article measures total factor productivity in industries that exploit resources held in common particular attention is paid to the valuation and specification of in situ commonproperty resources in a neoclassical production technology catchability of the resource and variations in economic capacity utilization an empirical analysis of the open access pacific coast trawl fishing industry demonstrates that disentangling the productivity residual from changes in resource abundance its catchability and variations in capacity utilization hones the productivity residual to finer precision lowering mean productivity growth by about hak removing biological noise from highly variable resources is also important the results are related to aprogram limiting the number of vessels and can contribute to sustainable resource management whenever resources are held in common

productivity scale economies and technical change reconsidered recently several writers have presented theoretical arguments and empirical evidence that suggests that an electric utility s long run productivity growth rate can be decomposed into a variety of factors for example gollop and roberts 12 decompose a utility s total factor productivity growth rate into three distinct components 1 technical change 2 a scale effect and 3 an environmental regulatory factor results for the 1970s indicate that declining rates of technical change and output growth coupled with increased regulatory intensity lead to a noticeable decline in the firm s long run productivity growth rate similarly nelson and wohar 15 examine the impact of technical change scale economies and rate of return regulation on an electric utility s longrun productivity growth rate evidence suggests that the technical change and scale components behaved in a manner similar to the gollop and roberts 12 findings the evidence concerning the impact of the regulatory factor was less convincing due to the difficulty in obtaining reliable estimates of the regulatory constraint parameter a common characteristic of this literature is that the firms under investigation are assumed to employ all inputs at their long run cost minimizing levels as such the productivity decomposition model is primarily concerned with distinguishing between shifts in the production function versus movements along the production structure according to caves christensen and swanson 5 a violation of the long run equilibrium assumption adds an equally important factor to the decomposition of productivity growth specifically the movement toward or away from longrun equilibrium as a consequence researchers must further distinguish between long run and short run productivity growth estimates 2 in a recent article 9 daly and rao illustrate theoretically and empirically using a long run cost function and data pertaining to ontario hydro that a firm s long run productivity growth rate can be decomposed into 1 technical change 2 non constant returns to scale and 3 a capacity

the impact of environmental regulations on industry productivity direct and indirect effects abstract the paper develops an approach to measuring the impact of environmental regulations on total factor productivity growth which is less restrictive than a simple growth accounting approach environmental regulations have a direct impact on productivity growth due to the diversion of resources toward required abatement capital there can be a further indirect effect however as conventional inputs and production processes are changed in response to requirements to purchase abatement capital we estimate this indirect effect using a flexible functional form cost function total factor productivity and the direct and indirect productivity effects of environmental regulations are presented for five polluting industries we find that the indirect effect can be either positive or negative and in all industries is energy using the net impact of environmental regulations on total factor productivity growth is fairly small given that these are the most polluting industries they account for about 10 30 of the productivity decline of the 1970s in these industries
