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

a nonparametric cost approach to scale efficiency starting with farrell fieldhouse 1962 a host of notiparametric models have been developed for calculation of scale efficiency a common property of these models is that they are specified in terms of input output data duality theory has taught us that technological characteristics may be analyzed from either the primal or the dual cost side the purpose of this paper is to introduce a nonparametric dual method of calculating scale efficiency

a note on the malmquist productivity index in recent years the malmquist index has gained in popularity as a measure of productivity change we demonstrate that in the presence of non constant returns to scale the malmquist productivity index does not accurately measure productivity change the bias is systematic and depends on the magnitude of scale economies

equivalence and implementation of alternative methods for determining returns to scale in data envelopment analysis abstract this paper discusses alternative methods for determining returns to scale in dea the methods for estimating returns to scale in dea as developed by banker 1984 banker charnes and cooper 1984 and banker and thrall 1992 are proved to be conceptually equivalent to the two stage methods of fare grosskopf and lovell 1985 when their assumptions apply here the emphasis is on the ccr model of dea and very simple methods are introduced for determining returns to scale locally with this model by reference to banker s concept of most productive scale size

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

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

beyond death do us part the long term implications of divorce perceptions on women s well being and child schooling in rural ethiopia summary this paper examines how women s perception of the division of household assets upon divorce affects women s well being and child schooling outcomes in rural ethiopia findings suggest that women who perceive that their husband would get all the assets in case of a divorce also tend to perceive less control over their lives implications of perceptions of unequal divorce allocations on child schooling are more striking not only do children in households where perceived divorce allocations favor the husband do worse compared to children of the same age but girls fare even worse than boys in these households

the efficiency and equity consequences of two part tariffs in electricity pricing ahstrat t this paper evaluates electricity two part tariffs with both efficiency and equity criteria the efficiency of tariffs is analyzed by studying the relation between price and marginal cost for both customer connection and variable output the equity of tariffs is addressed by an analysis of cross subsidization to address these issues this paper presents a multiproduct cost function that can provide information on output and connection marginal costs for each customer class using a 1980 cross section of electric utilities it is shown that prices are not set in a first best efficient manner and least favor the commercial class

environmental regulations and industrial competitiveness evidence from china economic activities are closely related to real world environmental issues currently more attention is paid to the association between environmental regulations and industrial competitiveness ic because of pressures on economic development and environmental protection in this study we identify and explain the association between environmental regulations and ic in china as the largest developing country in the world china has the unavoidable responsibility of protecting the environment and promoting global economic development we analyse the mechanisms behind environmental regulations and industrial competiveness at the provincial level and conclude that the impact of environmental regulations upon ic is not a simple linear one but a u shaped relationship it is argued that the crucial intervention to activate the u shaped relationship or porter s hypothesis is innovation which can be triggered by stringent regulations and well designed policies

measuring hospital performance a non parametric approach abstract in this paper a technique for assessing the relative performance of firms is introduced and applied to a sample of hospitals in california hospitals are compared on the basis of their relative technical efficiency the reference technology is constructed from observed outputs and inputs including physicians using programming techniques and efficiency is assessed relative to the frontier of the technology using measures similar to those suggested by farrell the technique used here imposes no prespecified functional form allows for multiple outputs and inputs allowing for differences in case mix and yields information on the productive performance of individual hospitals this technique can also be used to determine whether different types of hospitals use different technologies our results although illustrative rather than definitive suggest that ownership affects efficiency as measured here public and nfp hospitals have different best practice frontiers and public hospitals appear to use relatively fewer resources these results could reflect differences in quality of care by ownership

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 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

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

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

greenwash vs brownwash exaggeration and undue modesty in corporate sustainability disclosure corporate greenwashing has accelerated in recent years bringing in its wake growing skepticism about corporate green claims although a theory of the drivers and deterrents of greenwashing has begun to emerge it is static in nature and does not incorporate the full range of ways in which firms can misrepresent their environmental performance our contribution is threefold first we extend the theory of organizational information disclosure to incorporate the possibility of undue modesty about a firm s environmental social and governance practices second we hypothesize about the drivers of exaggeration and undue modesty based on which of a firm s stakeholders are salient at a given point in time to do so we place the firm within a dynamic context that has largely been missing in the prior literature third we test our hypotheses using a data set that allows us to directly compare corporate green claims against actual performance results reveal that corporate output growth deregulation and low profits under deregulation significantly affect the choice between greenwashing and brownwashing the effects of growth and profits are mitigated by external scrutiny

the costs of water pollution regulation in the pulp and paper industry this paper studies plant level data on actual and permitted levels of water pollution emissions for the pulp and paper industry there is widespread and substantial overcompliance with the relevant regulations aggregate bod emissions in 1992 were only 50 of the amount allowed overcompliance appears to imply a zero marginal abatement cost and its prevalence therefore has the potential to substantially change the debate over the costs of regulation we show instead that plants incurred substantial costs to overcomply marginal abatement costs were roughly 13 000 ton in 1992 we discuss possible explanations for costly overcompliance and their implications for estimation

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

decomposing world health inequality this study explores global inequality in health status and decomposes it into within and between country inequality we rely on standardized height as our health indicator since it avoids the measurement pitfalls of more traditional measures of health such as morbidity mortality and life expectancy it also avoids measurement problems associated with using monetary variables such as income or expenditure across time or place to compare welfare our calculation of world height inequality indicates that in contrast with similar research on income inequality within country variation is the source of most inequality rather than the differences between countries

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

food aid and child nutrition in rural ethiopia abstract this paper uses a unique panel data set from ethiopia to examine the determinants of participation in and receipts of food aid through free distribution fd and food for work ffw results show that aggregate rainfall and livestock shocks increase household participation in both fd and ffw ffw also seems well targeted to asset poor households the probability of receiving fd does not appear to be targeted based on household wealth but fd receipts are lower for wealthier households the effects of fd and ffw on child nutritional status differ depending on the modality of food aid and the gender of the child both ffw and fd have a positive direct impact on weight for height households invest proceeds from fd in girls nutrition while earnings from ffw are manifested in better nutrition for boys the effects of the gender of the aid recipient are not conclusive

gender gaps in landownership across and within households in four asian countries using nationally representative data from bangladesh tajikistan timor leste and vietnam this paper investigates which individual and household characteristics influence men s and women s landownership across and within households often neglected in household level statistics married women in all countries are landowners across different household structures women own less land than men and less land relative to the household average as household landholdings increase increasing gender inequality with household wealth cannot be consistently explained by an increasing share of household land devoted to crops findings support the need to strengthen women s land rights within marriage and to protect them should the marriage dissolve

separability test for the electricity supply industry this paper examines the vertical integration issue of the electricity industry this industry is typically vertically integrated and heavily regulated the paper investigates the potential technological efficiency loss due to the vertical disintegration using the translog production function three separability hypotheses using the allen uzawa elasticity of substitution are tested to examine the feasibility of various degrees of disintegration of the current industry structure all three separability hypotheses are rejected and the cost of disintegration is estimated further estimates indicate that the electricity industry appears to have exhausted economies of scale unlike other deregulated industries disintegration of the electricity industry will entail technological efficiency loss

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

gender and say a model of household behaviour with endogenously determined balance of power the evidence that the same total income can lead a household to choose different consumption vectors depending on who brings in how much of the income has led to an effort to replace the standard unitary model of the household with the collective model which recognizes that the husband and the wife may have different preferences and depending on the balance of power between them the household may choose differently one weakness of this new literature is that it fails to recognize that the household s choice could in turn influence the balance of power once this two way relation between choice and power is recognized we are forced to confront some new questions concerning how to model the household this paper tries to answer these by defining a household equilibrium examining its game theoretic properties and drawing out its testable implications it is shown for instance that once we allow for dynamic interaction a household can exhibit inefficient behavior and that for a certain class of parameters children will be less likely to work in a household where power is evenly balanced than one in which all power is concentrated in the hands of either the father or the mother the paper also draws out the implications for female labor supply

enforcement leverage when penalties are restricted in the united states empirical studies of the enforcement of continuous compliance with environmental regulations especially air and water pollution regulations have repeatedly demonstrated the following i for most sources the frequency of surveillance is quite low ii even when violations are discovered fines or other penalties are rarely assessed in most states iii sources are nonetheless thought to be in compliance a large part of the time the evidence for the apparently low level of enforcement activity is found in a number of case studies of state and local enforcement of air and water quality regulations conducted jointly by the environmental protection agency epa and council on environmental quality ceg together with periodic surveys of implementation of air and water quality legislation conducted by the general accounting office gao these surveys show

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource 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

the use of data envelopment analysis in the regulation of uk water utilities water distribution abstract regulation is increasingly playing a major role in defence of the public interest in the uk and other economies in the aftermath of the privatisation of utilities operating in near monopoly environments this paper gives an account of the use of data envelopment analysis dea by the regulator of water companies in england and wales in 1994 in the context of setting price limits dea is a general purpose linear programming based method for assessing the productive efficiencies of operating units such as bank branches or schools the paper details the use of dea to estimate potential savings in the specific context of water distribution and discusses the use of the results obtained it also highlights certain generic issues arising in the use of dea and more generally performance measurement methods in the regulatory context

estimating most productive scale size using data envelopment analysis abstract the relation between the most productive scale size mpss for paparticular input and output mixes and returns to scale for multiple inputs multiple outputs situations is explicitly developed this relation is then employed to extend the applications of data envelopment analysis dea introduced by charnes cooper and rhodes ccr to the estimation of most productive scale sizes for convex production possibility sets it is then shown that in addition to productive inefficiencies at the actual scale size the ccr efficiency measure also reflects any inefficiencies due to divergence from the most productive scale size two illustrations of the practical applications of these results to the estimation of most productive scale sizes and returns to scale for hospitals and stem electric generation plants are also provided emphasize the advantage of this method in examining specific segments of the efficient production surface

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

do exogenous shocks better leverage the benefits of technological change in the staged elimination of differential environmental regulations evidence from china s cement industry before and after the 2008 great sichuan earthquake abstract technological modernization is crucial for productivity and environmental management and has profound implications for china where both overproduction and industrial pollution are serious issues this study reports empirical results for existing cement plants in sichuan province in china capturing changes in productivity and environmental performance between 2007 and 2010 during this time period as the moratorium period of differential environmental regulations came to an end certain existing plants modernized their production processes after the great sichuan earthquake in 2008 using primary data and the directional distant function approach this study investigates the financial and environmental benefits of technological modernization by examining improvements in productivity and environmental performance we find that the decision to modernize by changing the production process from conventional vertical shaft kilns vsks to modern dry rotary kilns as part of a cleaner production strategy yields significant savings in pollution abatement costs without compromising production efficiency we compare this modernization strategy to a reference strategy whereby firms continued to use vsk technology and invested in end of pipe technology to satisfy stricter environmental regulations we find that the environmental benefits of technological modernization are approximately three times greater than the non environmental financial benefits when environmental benefits are considered the payback period is significantly reduced going from 8 97 years to 2 26 years

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

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

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

gender assets and agricultural development lessons from eight projects ownership of assets is important for poverty reduction and women s control of assets is associated with positive development outcomes at the household and individual levels this research was undertaken to provide guidance for agricultural development programs on how to incorporate gender and assets in the design implementation and evaluation of interventions this paper synthesizes the findings of eight mixed method evaluations of the impacts of agricultural development projects on individual and household assets in seven countries in africa and south asia the results show that assets both affect and are affected by projects indicating that it is both feasible and important to consider assets in the design implementation and evaluation of projects all projects were associated with increases in asset levels and other benefits at the household level however only four projects documented significant positive impacts on women s ownership or control of some types of assets relative to a control group and of those only one project provided evidence of a reduction in the gender asset gap the quantitative and qualitative findings suggest ways that greater attention to gender and assets by researchers and development implementers could improve outcomes for women in future projects

rural women s access to credit market imperfections and intrahousehold dynamics summary credit rationing studies carried out at the household level and based on responses from male heads of households present an incomplete and biased assessment of who is likely to be constrained why they are constrained and what is the extent of the constraints they ignore possibly conflictive intrahousehold dynamics and assume that imperfections in rural financial markets are gender neutral this paper addresses both issues theoretically and empirically the semi cooperative household model developed for this analysis formalizes the conditions under which spouses and particularly women s individual access to credit can be affected by their own position in the financial market as well as by intrahousehold dynamics these notions are then explored empirically using husbands and wives individual perceptions of their access to credit in rural paraguay the most significant empirical findings of the paper are that i compared to men women are more likely to be credit constrained ii women s rationing status responds to a different set of factors than men s and iii husbands may choose not to intermediate capital to their wives even when they are able to do so results from this exercise provide empirically sound support for the assumptions underlying women targeted credit programs

how do environmental regulation and environmental decentralization affect green total factor energy efficiency evidence from china abstract green development is critical for china s economic transformation enhancing green total factor energy efficiency hereafter gtfee is vital to emission reduction and to win win industrial development this study uses the panel data of 30 chinese provinces for the period 2005 2016 to investigate the relationship between environmental regulation and china s gtfee the spatial durbin model is employed to control for the possible spatial spillover effect a dynamic threshold panel model that can effectively address the endogeneity problem and regional heterogeneity is utilized to examine the potential non linear relationship between environmental regulation and gtfee under different conditions of environmental decentralization the estimation results indicate that there is a significant u shaped relationship between environmental regulation and china s gtfee with the further expansion of environmental decentralization the local government s autonomous choice of pollution control is improved the improvement of environmental decentralization can lead to negative moderating effect of environmental regulation on gtfee additionally the regression results of dynamic threshold model show that environmental decentralization can increase the negative influences of environmental regulation on gtfee interestingly the non linear impact of environmental regulation on gtfee is dependent on the specific type of environmental decentralization higher degree of environmental decentralization can lead to an increase in the restraining effect of environmental regulation on gtfee however an improvement in the decentralization of environmental supervision and environmental monitoring can increase the negative influences of environmental regulation on gtfee

voluntary compliance with market based environmental policy evidence from the u s acid rain program the u s acid rain program implemented a nationwide market for electric utilities sulfur dioxide so2 emissions and included voluntary compliance possibilities for nonaffected sources i observe significant voluntary participation albeit with small impact on the so2 market mostly from sources with counterfactual emissions below their allowance allocations an ex post analysis suggests that costs from the resulting higher emissions outweigh savings from shifts in emissions reductions from high cost affected sources to low cost nonaffected sources further utilities voluntary participation is well explained by economic variables which provides new evidence of cost effective compliance strategies and low transaction costs

do spouses realise cooperative gains experimental evidence from rural uganda summary we use experimental data from variants of public good games to test for household efficiency among married couples in rural uganda spouses frequently do not maximise surplus from cooperation and perform better when women are in charge of allocating the common pool women contribute less to this household common pool than men and opportunism is widespread these results cast doubts on many models of household decision making experimental results are correlated with socio economic attributes and suggest that assortative matching improves household efficiency developing non cooperative household models sensitive to the context specificity of gender relations emerges as a promising future research agenda

productivity growth and pollution in state manufacturing the directional output distance function chambers chung fare 1996 is used to construct a malmquist luenberger index of total factor productivity growth for manufacturing when both good and bad outputs are jointly produced the index is constructed using information on good and bad output quantities and input quantities circumventing the problem of recovering shadow price information for the bad output needed for the fisher or tornqvist type of productivity indices accounting for toxic releases in manufacturing productivity growth averages 1 4 an nually during 1988 1994 the findings also suggest that the failure to account for toxic releases in manufacturing results in a significant under statement of total factor productivity growth

the effect of within sector upstream and downstream energy taxes on innovation and productivity the aim of this paper is to investigate the effect of environmental regulatory stringency on innovation and productivity using a panel of 8 european countries for 13 manufacturing sectors over the years 2001 2007 this research topic falls under the heading of the porter hypothesis ph of which different versions have been tested we consider both the strong and the weak versions of the ph while also adding some peculiar features to the analysis firstly we assess the role played by environmental taxes that is an instrument rarely tested as a factor which can support the ph secondly we analyse not only the effect of environmental taxes within a given sector within sector but also the role played by environmental taxes in upstream and downstream sectors in terms of input output relationships thirdly we test these relationships also indirectly by verifying whether innovation is one of the channels through which higher sectoral productivity can be achieved by imposing tighter environmental regulations our main findings suggest that downstream stringency is the most relevant driver of innovation and productivity while within sector regulations only affect productivity but not innovation moreover the effect of regulations on productivity is mostly direct while the part of the effect mediated by induced innovations as measured by patents is relevant only for what concerns downstream regulations

different types of environmental regulations and heterogeneous influence on green productivity evidence from china this paper attempts to examine if the strong version of porter hypothesis is supported in china by investigating how different regulatory instruments and the relative stringency impact green productivity we use a slacks based measure sbm and luenberger productivity index accounting for undesirable outputs to evaluate the industrial green productivity growth rates of china s 30 provinces the estimates imply an unsustainable development model in china with significant regional differences by employing a panel threshold model and a province level panel dataset during 2000 2012 empirical results show that both command and control and market based regulation have a non linear relationship with and can be positively related to green productivity but with different constrains on regulation stringency there are double thresholds with the command and control and exists an optimal range of stringency for productivity improvement while a single threshold has been found with the market based regulation and its current stringency is reasonable for most of provinces moreover based on china s reality the productivity effect driven by market based regulation is much stronger than that of the command and control the mechanism of informal regulation is much more complicated consequently we find evidence to support the strong porter hypothesis that reasonable stringency of environmental regulations may enhance rather than lower industrial competitiveness

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

firms compliance to environmental regulation is there really a paradox it has often been claimed that firms compliance to environmental regulations is higher than predicted by standard theory a result labeled the harrington paradox in the literature enforcement data from norway presented here appears at first glance to confirm this stylized fact firms are inspected less than once a year detected violators are seldom fined but still serious violations seem relatively rare however at a closer look the pattern seems less paradoxical enforcement of minor violations is lax but such violations do flourish serious violations on the other hand are subject to credible threats of harsh punishment and such violations are more uncommon this seems quite consistent with predictions from standard theory we argue that the empirical existence of the harrington paradox is not well documented in the international literature the claim that firms compliance with environmental regulations is generally higher than predicted by standard theory should thus be regarded as a hypothesis rather than an established fact

land inheritance and schooling in matrilineal societies evidence from sumatra abstract this paper explores statistically the implications of the shift from communal to individualized tenure on the distribution of land and schooling between sons and daughters in matrilineal societies based on a sumatra case study the inheritance system is evolving from a strictly matrilineal system to a more egalitarian system in which sons and daughters inherit the type of land which is more intensive in their respective work effort while gender bias is either non existent or small in land inheritance daughters tend to be disadvantaged with respect to schooling the gender gap in schooling however appears to be closing for the generation of younger children

enhancing nutrition a new tool for ex ante comparison of commodity based vouchers and food transfers summary this article presents a new analytical tool for ex ante comparison of the cost effectiveness of two transfer modalities in pursuing specific nutritional objectives it does so by introducing a metric to score the nutrient value of a food basket the nutrient value score nvs and explains how this metric can be combined with full supply chain analysis and costing to generate a new tool the omega value the use of the omega value allows policy makers who design a program with nutrition objectives to compare direct food transfers and commodity based food vouchers in terms of both cost efficiency and cost effectiveness 2013 elsevier ltd all rights reserved

environmental compliance and economic and environmental performance evidence from handicrafts small businesses in mexico this research aims to fill a major gap in the relevant literature on small businesses in developing countries specifically concerning the development of models to better explain economic and environmental performance as a result of environmental compliance thus moving toward an explanation of the sustainable behavior of these businesses data from 186 pottery craft businesses located in three mexican states oaxaca puebla and tlaxcala reveal that environmental compliance significantly influences economic and environmental performance with the mediating role of environmental innovation confirming the porter hypothesis in the context of small businesses in an emerging economy environmental compliance is an important factor in improving the economic and environmental performance of small businesses in emerging economies

case study evidence that direct regulation remains the main driver of industrial pollution avoidance and may benefit operational efficiency abstract environmental regulation is required to reduce industrial pollution to levels that are socially acceptable and economically efficient but there is debate over the most efficient form of such regulation typically a limited range of environmental and economic parameters are accounted for in the econometric studies that inform that debate this paper integrates evidence from two separate studies to assess a broad range of parameters related to the efficiency of industrial environmental regulation questionnaire responses from 25 italian manufacturers of building chemicals and 28 irish pharmaceutical manufacturers provided evidence on the environmental effectiveness and operational impacts of different regulatory instruments combined with extensive emissions data from irish pharmaceutical manufacturers survey results enabled a quantitative estimation of pollution avoidance specifically attributable to direct regulation the monetised social benefit of avoided pollution was found to be equal to direct compliance costs chemical manufacturers in italy and ireland stated that direct regulation is a more important driver of industrial environmental performance than economic or voluntary regulation and their responses indicated that direct compliance costs may be countered somewhat by stimulated operational improvements it was concluded that direct regulation is an effective approach for multi pollutant control in an industrial context and that the efficiency of such regulation may be underestimated in studies that do not consider the full range of pollutants and operational effects

a century long perspective on agricultural development this article strategically surveys the past century s literature on agricultural development we organize the discussion around three grand themes that reveal the richness of agricultural development as an intellectual endeavor first we explore the role of agriculture in the broader development process from a macroeconomic and political economy perspective we then examine the role of technological and institutional change in successful agricultural development finally the focus turns to a microeconomic perspective on agricultural household decision making and the problems of imperfect and missing markets asymmetric information and transactions costs that lead to widespread apparent inefficiency and disequilibrium

some urban facts of life implications for research and policy abstract this review of recent literature explores the challenges to urban food and nutrition security in the rapidly urbanizing developing world the premise of the manuscript is that the causes of malnutrition and food insecurity in urban and rural areas are different due primarily to a number of phenomena that are unique to or exacerbated by urban living these areas include a a greater dependence on cash income b weaker informal safety nets c greater labor force participation of women and its consequences for child care d lifestyle changes particularly diet and exercise patterns e greater availability of public services but questionable access by the poor f greater exposure to environmental contamination and g governance by a new possibly nonexistent set of property rights the main focus is on identifying what is different about urban areas so as to better frame the program and policy responses

do environmental regulations hamper productivity growth how accounting for improvements of plants environmental performance can change the conclusion abstract many economists maintain that environmental regulations hamper productivity growth a view supported by several empirical studies on industry or state level data however there is little research of the relationship between the stringency of environmental regulation and productivity growth at the plant level and the results of the few existing studies are ambiguous moreover the measures of productivity growth applied in previous studies do not credit plants for emission reductions and this may result in understatement of productivity growth we perform regression analyses of productivity growth on regulatory stringency using plant level data to credit a plant for emission reductions we include emissions as inputs when calculating an environmental malmquist productivity index emi and do not include emissions when calculation the traditional malmquist productivity index mi the regression analyses show that the overall effect of the regulatory stringency faced by plants on plants productivity growth is statistically insignificant when mi is applied to measure productivity growth however when we apply emi the effect is positive and statistically significant this indicates that not accounting for emission reductions when measuring productivity growth can result in too pessimistic conclusions regarding the effect of regulatory stringency on productivity growth

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

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

should transfers to poor families be conditional on school attendance a household bargaining perspective this article considers the welfare implications of transfers to poor families that are conditional on school attendance and other forms of investment in children s human capital family decisions are assumed to be the result of generalized nash bargaining between the two parents we show that as long as bequests are zero conditional transfers are better for children than unconditional transfers the mother s welfare may also be improved by conditional transfers thus conditioning transfers to bequest constrained families have potentially desirable intergenerational and intragenerational welfare effects conditioning transfers to unconstrained families make every family member worse off

a variable returns to scale data envelopment analysis model for the joint determination of efficiencies with an example of the uk health service a multi activity dea model for the joint determination of efficiencies with variable returns to scale is developed in this paper the model contains an element of complexity that is not present in the previous dea models for estimating returns to scale it is found that apparent overall efficiency may hide scale inefficiency in individual activities the model is applied to study the performance of individual specialties of national health services trusts in the uk it is argued that efficiency can be defined from two different perspectives either as the most efficient internal allocation of resources or the most efficient overall allocation of resources this distinction becomes important when looking at the efficiency of parts of inefficient dmus the relationship between size and returns to scale is also explored this method allows the determination of optimal size of an activity

environmental efficiency of land transportation in china a parallel slack based measure for regional and temporal analysis abstract as the second largest economic entity in the world china plays an important role in controlling global carbon dioxide co 2 emissions the land transportation sector including railway transportation and road transportation has been the most important source of emissions in china and the average co 2 emissions of land transportation were 529 31 million tons during the period 2009 2012 in this study a parallel slack based measure data envelopment analysis model is proposed which is used for evaluating the overall efficiency of the land transportation sector and individual efficiencies of the railway transportation and highway transportation subsectors at the same time considering co 2 emissions the empirical results lead to three conclusions a only anhui province is efficient each year during 2009 2012 b the environmental efficiency of the eastern area in china is the best followed by the central area with the western area being the worst c the performance of railway transportation is better than that of highway transportation these three conclusions lead to policy suggestions to promote highway transportation technological innovation and narrow the regional imbalances in land transportation this paper makes two main contributions the model advances improvements to methods used in the data envelopment analysis technique and also provides governments with a practical and yet easy to adopt perspective to implement land transportation performance measurement that aids in decision making

the sensitivity of productivity growth measures to alternative structural and behavioral assumptions an application to electric utilities 1951 1984 this article examines the sensitivity of three alternative multifactor productivity growth estimates for the electric utility industry during the 1951 1984 period the results indicate that multifactor productivity growth estimates are quite sensitive to the relaxation of various structural and behavioral assumptions first a benchmark measure is constructed along the lines suggested by solow 1957 this residual approach produces estimates that suggest a substantial decline in firm level productivity growth after the mid 1960s prior to obtaining the second and third estimates empirical tests of the structural and behavioral assumptions underlying a firm s operation are conducted first the structural assumption of constant returns to scale is rejected and the resulting long run scale adjusted multifactor productivity growth estimates are found to be consistently less than the residual estimates second the behavioral assumption of long run equilibrium is rejected comparing the long run scale ad

an activity analysis model of the environmental performance of firms application to fossil fuel fired electric utilities the productivity of firms when some outputs pollution are undesirable has been studied in the literature for some time in this paper we introduce an environmental performance indicator based on the decomposition of overall factor productivity into a pollution index and an input output efficiency index this indicator is compared to the more conventional jaggi and freedman 1992 model results are given for illustrative purposes using data from u s fossil fuel fired electric utilities the rankings of the utilities obtained with the two models show significant divergence which is due to the different ways in which the undesirable outputs are dealt with as well as due to the different possible tradeoffs between the pollutants released into the atmosphere and the resources used as inputs

a comparative application of data envelopment analysis and translog methods an illustrative study of hospital production this paper compares inferences about hospital cost and production correspondences from two different estimation models 1 the econometric modeling of the translog cost function and 2 the application of data envelopment analysis dea while there are numerous examples of the application of each approach to empirical data this paper provides insights into the relative strengths of the estimation methods by applying both models to the same data the translog results suggest that constant reruns are operant whereas the dea results suggest that both increasing and decreasing returns to scale may be observed in different segments of the production correspondence in turn suggesting that the translog model may be averaging diametrically opposite behavior on the other hand by examining the rate of output transformation both models agree that patient days devoted to care of children are more resource intensive than those devoted to adults or to the elderly in addition we compare estimates of technical efficiencies of individual hospitals obtained from the two methods the dea estimates are found to be highly related to the capacity utilization but no such relationship was found for the translog estimates this comparative application of different estimation models to the same data to obtain inferences about the nature of underlying cost and production correspondences sheds interesting light on the strengths of each approach and suggests the need for additional research comparing estimation models using real as well as simulated data

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

environmentally sensitive productivity analysis of the canadian pulp and paper industry 1959 1994 an input distance function approach abstract this study employs a parametric input distance function that incorporates both desirable and undesirable outputs to provide a more complete representation of the production technology from which environmentally sensitive productivity and efficiency measures can be generated this framework also generates pollution abatement cost estimates that are useful for policy making an input based malmquist index of productivity growth that appropriately credits the producer not only for increases in marketable or desirable outputs but also for the production of improved environmental quality through pollution abatement activities is derived from the input distance function the method was applied to time series data from the canadian pulp and paper industry our shadow price estimates indicate that the marginal cost to producers of pollution control has been rising the main conclusion of this study is that productivity improvement from the social viewpoint has been stronger than conventional measures would suggest

sensitivity analysis for dea models an empirical example using public vs nfp hospitals abstract the research presented here applies the data envelopment analysis dea to a sample of public government owned and not for profit hospitals operating in michigan in 1982 the focus of this research is twofold first assessing the relative efficiency between these two ownership types using the dea rather than cost or profit functions can add insights into the production practices of these two ownership forms of hospitals second testing the sensitivity of the dea will add credence to this approach and resulting measures ten different specifications of the dea are employed to test the sensitivity of the model

economic efficiency and frontier techniques abstract most of the literature related to the measurement of economic efficiency has based its analysis either on parametric or on non parametric frontier methods the choice of estimation method has been an issue of debate with some researchers preferring the parametric and others the non parametric approach the aim of this paper is to provide a critical and detailed review of both core frontier methods in our opinion no approach is strictly preferable to any other moreover a careful consideration of their main advantages and disadvantages of the data set utilized and of the intrinsic characteristics of the framework under analysis will help us in the correct implementation of these techniques recent developments in frontier techniques and economic efficiency measurement such as bayesian techniques bootstrapping duality theory and the analysis of sampling asymptotic properties are also considered in this paper

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

women s power conditional cash transfers and schooling in nicaragua the social safety net red de proteccion social rps program in nicaragua is one of many conditional cash transfer programs that pay households cash stipends in exchange for school attendance and regular visits to health clinics by the children a key feature is that payments go to the female head of household previous research suggests that exogenous transfers to women are more likely to be spent on their children s health nutrition and education and thus to reinforce the goals of these programs randomized experimental data from rps are used to test for heterogeneous program impacts on school enrollment and spending based on a woman s power as proxied by her years of schooling relative to her husband s years of schooling the results confirm previous findings that more household resources are devoted to children when women are more powerful however when a woman s power greatly exceeds her husband s additional female power reduces school enrollment rps impacts on schooling are much larger than the expected income effects estimated from the control group although no evidence is found that female power alters the impact of rps on school enrollment the conditionality of rps is probably decisive while rps significantly increases food and education expenditures the impact is attributable primarily to income effects

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
