towards an attention based view of the firm the central argument is that firm behavior is the result of how firms channel and distribute the attention of their decision makers what decision makers do depends on what issues and answers they focus their attention on what issues and answers they focus on depends on the specific situation and on how the firm s rules resources and relationships distribute various issues answers and decision makers into specific communications and procedures the paper develops these theoretical principles into a model of firm behavior and presents its implications for explaining firm behavior and adaptation 1997 by john wiley sons ltd

theories of the price and quantity of physician services a synthesis and critique abstract in the traditional neoclassical model of supply and demand prices determine the allocation of economic resources the difficulty in applying this model to physician services is the rationing of resources directly by physicians themselves eliminating the allocative function of prices welfare consequences are appropriately judged in terms of efficiency and equity not departures from the structural relationships implied by supply and demand as interpreted here both competitive theories and target income theories of this market imply that physicians consider both their own welfare and the welfare of their patients in their decision making all consumer benefits and all producer costs are internalized by physicians they consequently have an incentive to obtain the maximum possible social benefit from the resources at their disposal to the extent that they are implicitly allowed to share in the resulting social gains the distributions of gains between patients and physicians is determined by professional ethics within bounds imposed by competitive forces

the demand for physician services evidence from a natural experiment this study exploits a natural experiment in belgium to estimate the effect of copayment increases on the demand for physician services it shows how a differences in differences dd estimator of the price effects can be decomposed into effects induced by the common average proportional price increase income effects and by the change in relative prices substitution effects the price elasticity of a uniform proportional price increase is relatively small 0 13 for men and 0 03 for women substitution effects are large especially for women but imprecisely estimated despite the substantial price increases the efficiency gain of the reform if any is modest

physician induced demand for surgery following up the earlier findings by fuchs on surgeon induced demand this paper makes numerous data and econometric improvements in conducting a test of neoclassical and inducement theories a simultaneous equation model is used to estimate physician demand and equilibrium fees for surgery from a sample of 350 psus over the 1969 76 period the results provide definite support for the notion of competitive market failure particularly in large metropolitan areas other things equal fees and utilization are higher in surgeon rich areas although our estimated shift elasticities were only about one third those found by fuchs a statistically significant albeit small price elasticity of demand for surgery was also obtained in contrast to fuchs increasing monopoly and disequilibrium models are also tested without altering the basic findings where surgeons were in short supply their availability significantly affected surgery rates although a small supply effect was found in plentiful areas as well

input orientated data envelopment analysis framework for measuring and decomposing economic environmental and ecological efficiency an application to oecd agriculture this paper presents an input orientated data envelopment analysis dea framework which allows the measurement and decomposition of economic environmental and ecological efficiency levels in agricultural production across different countries economic environmental and ecological optimisations search for optimal input combinations that minimise total costs total amount of nutrients and total amount of cumulative exergy contained in inputs respectively the application of the framework to an agricultural dataset of 30 oecd countries revealed that i there was significant scope to make their agricultural production systems more environmentally and ecologically sustainable ii the improvement in the environmental and ecological sustainability could be achieved by being more technically efficient and even more significantly by changing the input combinations iii the rankings of sustainability varied significantly across oecd countries within frontier based environmental and ecological efficiency measures and between frontier based measures and indicators

weak disposability in nonparametric production analysis reply to fare and grosskopf fare and grosskopf this issue claim that a single abatement factor suffices for modeling weak disposability in nonparametric production models and that the kuosmanen 2005 technology that uses multiple abatement factors is larger than necessary this article demonstrates by a numerical example that a single abatement factor does not suffice to capture all feasible production plans and that its use leads to the violation of convexity one of the maintained assumptions of the model we also prove that the kuosmanen technology is the correct minimum extrapolation technology under the stated axioms

a behavioral theory of r d expenditures and innovations evidence from shipbuilding i base an integrated model of innovation development and launch on the behavioral theory of the firm this model specifies that research and development expenses are increased when low performance causes problemistic search and when excess resources cause slack search innovations generated by search are launched if low performance gives managers high risk tolerance using data from shipbuilding firms i show that high performance reduces r d intensity and innovation launches and high slack increases r d intensity as predicted

selfish bakers caring nurses a model of work motivation abstract work contributes to people s self image in important ways we propose a model in which effort is unobservable and where individuals have a preference for being important to others this gives the following predictions 1 if a worker s effort is paid by his marginal productivity bakers effort is just like in the standard model 2 if a worker s wage is unaffected by his effort nurses more effort is provided than in the standard model 3 to prevent that shirkers become nurses nurses wages must be kept strictly lower than bakers income at this wage level there will be too few nurses 4 overinvestment in nursing equipment can be justified as a means to attract motivated nurses 5 even with full income compensation both nurses and bakers may experience a net utility loss when losing their job 6 similarly both nurses and bakers may prefer work to welfare even with full income compensation

patients trust and the quality of physicians patients are uncertain of physicians quality but learn about the quality of particular physicians through experience in treatment patients come to trust physicians who have served them well this paper explores the economic consequences of patients learning and trust within a model of the market for physicians services in a market equilibrium there are too many incompetent physicians in practice surprisingly even the more competent physicians have an interest in preventing patients from judging quality except through experience as we show all physicians including the most competent may oppose steps to inform patients of physicians quality

medical interventions among pregnant women in fee for service and managed care insurance a propensity score analysis this paper extends earlier research on the effect of managed care on the receipt of four medical interventions for pregnant women ultrasound induction stimulation of birth electronic fetal monitor and caesarean delivery propensity score methods are used to account for sample selection issues regarding insurance choice managed care enrollees are more likely to receive an ultrasound which may be indicative of receiving better prenatal care managed care plans reduce the rate of caesarean deliveries but such limitations may be beneficial given the substantial medical evidence that caesarean deliveries are over utilized the results indicate that insurance coverage does influence treatment intensity but that utilization controls and provider financial incentives do not adversely affect care for pregnant women

efficiency and environmental regulation this paper proposes an extension of the enhancedefficiency indices of fare grosskopf lovell andpasurka 1989 that considers undesirable outputsasymmetrically by assuming that firms can freelydispose of some undesirable productions but areduction of other bad outputs generates a cost interms of desirable outputs this methodologicalapproach is used to analyse the relative efficiency ofa sample of spanish producers of wooden goods andfurnishings whose production process generates fourdifferent wastes we obtain efficiency indices thatserve to measure the impact on firm performance inseveral scenarios related to environmental regulationsaimed to reduce the production of wastes whenenvironmental regulations are assumed it is foundthat firms would have to sacrifice important amountsof potential desirable output in order to reallocateinputs into waste reduction secondly we find thatfirms associated with a technological institute aswell as firms located at a marshallian type industrialdistrict are likely to be less affected byregulations

identification of supplier induced demand in the health care sector this paper explores the issues and pitfalls encountered when attempting to test empirically the hypothesis that physician hospital or any other input supply level induces increasing demand for health services in the strict sense of demand shift and through that increased demand for the input in question evidence is presented which suggests that an empirical test of the supplier induced demand sid hypothesis of the type traditionally performed may not in fact be feasible with cross sectional aggregate data such as is usually used

neoclassical growth the j curve for abatement and the inverted u curve for pollution abstract this paper reexamines the neoclassical environmental growth model of forster to gain insights into the dynamic relationships among pollution abatement effort and economic development whereas the model has heretofore been used to examine steady state levels of capital consumption and environmental quality it also provides a theoretical basis for recent empirical research on j curves for abatement effort and inverted u curves for pollution

technology and health expenditures a demand approach applied to a process innovation there is controversy among economists as to whether the diffusion of new medical technologies has been a contributing factor to rising health expenditures the economic literature is critically reviewed and another approach is advocated this alternative approach rests on the distinction between product and process innovations it is argued that the relationship between process innovations and health expenditures can be illuminated by determining if the process innovation and the original procedure are utilized as substitutes the empirical results provide no indication that alternative technologies for diagnosing diseases conditions of the upper gastrointestinal tract have been utilized as substitutes by australian medical practitioners operating on a fee for service basis this study finds no evidence to indicate that the process innovation of fibre optic endoscopy has reduced health expenditures associated with diagnosis of diseases conditions of the upper gastrointestinal tract

a comment on weak disposability in nonparametric production analysis in his 2005 paper in this journal kuosmanen argues that shephard s specification of weak disposability in activity analysis dea models is not correct we show that shephard s specification does satisfy weak disposability and is the smallest technology to do so

a theory of physician behavior with supplier induced demand the health care crisis of the 1960 s and 1970 s fueled unprecedented efforts by the congress to control costs and at the same time improve access to care as a basis for policy the economics literature offers confusing direction consisting of alternative theories of demand 9 13 theories of market structure 12 5 11 10 and theories of physician behavior and supply response 4 1 at the most fundamental levels of controversy economists have not resolved the issues of demand creation satisficing behavior and targeted income in the modelling of the physician firm the notion that health care markets may be dominated by the health care provider s ability to create demand was introduced formally in newhouse 12 evans parish and sully 4 green 8 and fuchs 6 all offer further refinement of the supplier induced model however as yet no formal presentation of such a theory exists to a large extent an analytical framework that incorporates the physician s decision making processes is absent and remains implicit in the empirical results found in the literature this paper presents a theoretical framework for a supplier induced model of physician behavior whereby we may compare and contrast its implications with those of the standard neoclassical model 1 the acknowledged strength of the supplier induced theory is its ability to explain empirical evidence which stands at odds with more traditional approaches in particular a number of studies have reported a direct association between physician density and physicians fees 12 7 2 that is as the stock of physicians increases the price of medi

the transition from dirty to clean industries optimal fiscal policy and the environmental kuznets curve abstract this paper investigates privately and socially optimal patterns of economic development in a two sector endogenous growth model with clean and dirty goods we consider a second best fiscal policy framework in which distortionary taxes jointly influence economic growth and environmental quality in this policy setting three conditions produce an environmental kuznets curve ekc i dirty output is bounded ii clean output grows endogenously and iii growth in the dirty sector reduces growth in the clean sector these conditions do not arise with a consumption externality but can emerge with a production externality endogenous labor supply implications are also investigated although not necessary for producing an ekc endogenous labor supply provides additional linkages that produce an ekc under circumstances in which it would otherwise not appear

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

a kuznets curve in environmental efficiency an application on oecd countries the role of the environment is an important issue in policy making andthe accurate assessment of the environmental conditions is vital inthis paper using nonparametric techniques an environmental efficiencyindex is developed for each of the oecd countries these indexes allowone both to do cross section comparisons on the state of each country sproduction process in its treatment of undesirable outputs and also totrace each country s modification of their production processesovertime furthermore in this study we investigate the factorsunderlying societies environmental concerns that eventually lead tochanges in the environmental efficiency the results provide furtherempirical evidence for the environmental kuznets curve hypothesis

a new test for supplier inducement and application to the canadian market for dental care abstract the hypothesis that dentists do not induce demand for their services is tested using reduced form estimates of the price elasticity of demand if demand is autonomous shifts in supply for whatever reason should generate equivalent estimates provided access costs change proportionately with shifts in supply if demand inducement is present demand can appear to be very elastic or very inelastic depending on what is causing the shift in supply each of three applications of this test conducted in the context of jointly estimated fee and quantity equations using annual canadian data for 1956 1989 rejects the no inducement hypothesis

the market for physicians services theoretical implications and an empirical test of the target income hypothesis over the period 1965 to 1977 expenditure for health care in the united states increased from 181 per capita to 697 per capita the share of gnp composed of health care expenditures grew from 5 9 in 1965 to 8 8 in 1977 over this same period the number of physicians in the u s increased from 153 physicians per 100 000 population to 194 physicians per 100 000 such startling figures have generated much interest in the economics of health care with special concern about physician behavior and its effects upon health care costs the frequent empirical finding of a positive partial correlation between physicians fees or earnings and the number of physicians per capita have led many observers to eschew standard supply and demand models in favor of models that allow physicians themselves to significantly affect the demand for their services an assumption that physicians influence demand can not by itself differentiate a model from standard microeconomic models a profit maximizing doctor possessing costless demand shifting powers would shift demand to the greatest possible extent and then choose price and quantity to maximize profits subject to that shifted demand function a demand shifting model can yield results which are qualitatively different from those predicted by a standard model only with a behavioral assumption other than profit maximization the assumption of satisficing behavior on the part of physicians is a common substitute numerous empirical findings have been cited as evidence of the validity of the satisficing with demand shifting models much of this evidence however has been obtained as a by product of estimates of the demand for physician services rather than as the result of the estimation of a supply induced demand with satisficing model this lack

does trade openness improve environmental quality the literature on trade openness economic development and the environment is largely inconclusive about the environmental consequences of trade this study treats trade and income as endogenous and estimates the overall impact of trade openness on environmental quality using the instrumental variables technique we find that whether or not trade has a beneficial effect on the environment varies depending on the pollutant and the country trade is found to benefit the environment in oecd countries it has detrimental effects however on sulfur dioxide so2 and carbon dioxide co2 emissions in non oecd countries although it does lower biochemical oxygen demand bod emissions in these countries we also find the impact is large in the long term after the dynamic adjustment process although it is small in the short term

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

eco efficiency and convergence in oecd countries this paper assesses the convergence in eco efficiency of a group of 22 oecd countries over the period 1980 2008 in doing so three air pollutants representing the impact on the environment of economic activities are considered namely carbon dioxide text co 2 nitrogen oxides text no mathrm x and sulphur oxides text so mathrm x furthermore eco efficiency scores at both country and air pollutant specific level are computed using data envelopment analysis techniques then convergence is evaluated using the recent approach by phillips and sul econometrica 75 1771 1855 2007 which tests for the existence of convergence groups first we find that eco efficiency has improved over the period with the exception of text no mathrm x emissions second switzerland is the most eco efficient country followed by some scandinavian economies such as sweden iceland norway and denmark in contrast southern european countries such as portugal spain and greece in addition to hungary turkey canada and the united states are among the worst performers finally we find that both the most eco efficient countries and the worst tend to form clubs of convergence

the effect of time price on the demand for medical care services this paper analyzes the effect of time price on medical care demand and describes use of a reservation wage question from a household survey to develop a measure of time price for obtaining medical care a comprehensive three equation model of the demand for female medical care services examines choice of provider entry demand and the demand for physician visits results show that provider choice is based primarily on economic factors and that an expected high time price discourages women from choosing a public provider and from seeking gynecological maternal health or family planning services during the year yet does not influence the number of visits made once care is used the estimated model shows that medical care demand equations should control for the type of provider chosen and the opportunity cost of time for alternative activities when testing for a negative time price effect of obtaining medical care

a conditional directional distance function approach for measuring regional environmental efficiency evidence from uk regions abstract this paper by using conditional directional distance functions as introduced by simar and vanhems j econometrics 166 2012 342 354 modifies the model by fare and grosskopf eur j operat res 157 2004 242 245 and examines the link between regional environmental efficiency and economic growth the proposed model using conditional directional distance functions incorporates the effect of regional economic growth on regions environmental efficiency levels the results from uk regional data reveal a negative relationship between regions gdp per capita and environmental inefficiency up to a certain gdp per capita level after that level it appears that the relationship becomes positive as an overall result the regional environmental inefficiency gdp per capita relationship appears to have a u shape form

profit or patients health benefit exploring the heterogeneity in physician altruism abstract this paper investigates physician altruism toward patients health benefit using behavioral data from hennig schmidt et al s 2011 laboratory experiment in the experiment medical students in the role of physicians decide on the provision of medical services the experimental setup allows us to identify the influence of profits and patients health benefit on the choice of medical treatment we estimate physician altruism the weight individuals attach to patients health benefit by fitting mixed logit and multinomial logit regression models to the experimental data estimation results provide evidence for physician altruism we find however substantial variation in the degree of physician altruism we also discuss some implications of our results for the design of physician payment schemes in the light of the theoretical literature

measuring the effect of economic growth on countries environmental efficiency a conditional directional distance function approach using a recently developed probabilistic approach of a conditional directional distance function we measure the effect of economic growth on countries environmental efficiency in carbon dioxide emissions for a sample of 99 countries over the period of 1980 2010 our approach directly accounts for the exogenous factors influencing countries environmental production therefore we do not impose the separability condition on the estimated environmental efficiencies when examining the entire sample as well as the sample of developed countries our results reveal an inverted u shaped relationship between countries gdp per capita and environmental efficiency however when examining the relationship for the sample of developing countries the results reveal an n shaped form moreover our results show that countries ratifying the kyoto protocol tend to have higher efficiency scores implying that their mitigation activity is less costly

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

forward shifting of the personal income tax by self employed canadian dentists in this paper two tests are conducted of the null hypothesis that self employed canadian dentists do not shift the burden of their personal income tax forward to their patients by charging higher real dental fees the first test using ordinary least squares estimation of a reduced form dental fee equation is based on an exogenous tax variable the second test uses two stage least squares estimation of a reduced form dental fee equation with an endogenous tax variable both tests reject the null hypothesis of no forward shifting and fail to reject the hypothesis that self employed canadian dentists shift forward 100 percent of their personal income tax burden

a model of physician behaviour with demand inducement we present a model of the physician patient relationship extending on the model by farley farley p j 1986 theories of the price and quantity of physician services journal of health economics 5 315 333 of supplier induced demand sid first we make a case for the way this model specifies professional ethics physician competition and sid itself second we derive predictions from this model and confront them with the neoclassical model finally we stress the importance of considering how sid affects patient welfare in providing an example where physicians ability to induce makes patients better off to evaluate patient welfare we derive approximations of the patients welfare loss due to physician market power in both the neoclassical model and the inducement model

economic growth and environmental efficiency evidence from us regions abstract this paper proposes a conditional directional distance function estimator in order to examine the link between regional environmental efficiency and gdp per capita levels as an illustrative example we apply our model to us regional data revealing an inverted u shape relationship between regional environmental efficiency and per capita income the results derived from a non parametric regression indicate a turning point at 49 000 dollars

antecedents of convergence and divergence in strategic positioning the effects of performance and aspiration on the direction of strategic change this paper investigates drivers of convergence and divergence in strategic positioning in terms of resource allocation decisions the study based on the behavioral theory of the firm suggests two unexplored kinked curve relationships between performance gaps and strategic convergence divergence first the study suggests a negative relationship between a focal firm s performance relative to aspiration levels and strategic convergence divergence where the slope is steeper when performance is above the aspiration level second it suggests a positive relationship between a target firm s performance relative to a focal firm s performance and strategic convergence divergence where the slope is steeper when a target firm s performance is below a focal firm s performance empirical analysis of dyad level data in the u s food processing industry reveals that the direction of a firm s strategic change is shaped by its aspiration level its performance level and the performance gap between it and the firm it selects as a model this study contributes to the current literature by offering preliminary indications of when and how a firm moves closer to or further away from other competing firms in its strategic position

total factor productivity and the environmental kuznets curve abstract empirical studies support the environmental kuznets curve hypothesis ekc for some pollutants as income increases pollution increases reaches a peak and eventually decreases while relying mostly on cross sectional data the interpretations assert that the ekc is a by product of economic growth over time in doing so and in neglecting the role of important country specific characteristics these studies overlook potential econometric problems and introduce policy misconceptions differences in total factor productivity tfps account for much of the variation in income across countries with important implications for environmental quality we develop a theoretical model where different tfps produce a cross sectional ekc even if the dynamic path of environmental quality to its steady state in individual countries suggest otherwise the cross sectional ekc depends on diminishing returns to scale in environmental protection on the curvatures of the utility function with respect to consumption and of the environmental protection function and the elasticities of steady state consumption and environmental expenditures with respect to variation in tfps

on the determination of the us aggregate health care expenditure per capita real health care expenditure is examined against three major groups of explanatory variables economic demographic and health stock and it is found that the three groups of variables have an impact on real health care spending other subcategories such as real private and government health care pharmaceutical dental home nursing ambulatory personal medical consumption and in patient expenditures have also been examined and have been found to be affected by the explanatory variables for several subcomponents there is evidence of supplier inducement of the demographic group of variables the ageing population had an impact only on the per capita real overall and private health care outlay and pharmaceutical spending also cointegrating relationships were found and consistent estimators of the elasticities found

searching for a kuznets curve in environmental efficiency using kernel estimation abstract the paper constructs environmental efficiency indexes for a sample consisting of high and low income countries using nonparametric production frontier techniques and then establishes an environmental kuznets relationship for environmental efficiency by nadaraya watson kernel estimation methodology

determinants of firms backward and forward looking r d search behavior this study develops and operationalizes a behavioral forward looking search model by incorporating prospect theory organizational risk literature and the logic of the behavioral theory of the firm with recognition of the bounded rationality of decision makers and the goal directed rule based nature of organizations this model suggests that a comparison between firms performance expectation and performance target translates the cognitive representation of the firms future into their subsequent actions by examining the research and development r d expenditures of u s manufacturing firms from 1980 to 2001 this study explores how performance aspirations expectations and slack affect decision making about firms r d search investments the findings show that both performance feedback and performance prospect are important determinants of firms search behavior after controlling for firm industry and time effects in addition backward and forward looking determinants have interactive effects on search behavior firms problem driven search activity further increases when firms feel unlikely to achieve the performance target for another year in contrast search intensity is reduced when firms expect to improve their performance from an underperforming situation to an outperforming situation the findings suggest that future research on performance feedback and experiential learning should also consider the effect of forward looking prospects on firm behavior

an empirical model of the demand for health care in belgium the paper presents an empirical model of the demand of health care in belgium the analysis pertains to 17 categories of medical care and to two subgroups of health insurance beneficiaries namely the active and the widows orphans pensioners and invalids the estimation results show that income and relative prices matter in the demand for medical care supplier induced demand is also detected for a number of medical care categories other explanatory variables in the model include the size of the child population climatic conditions and a time trend representing technological advances in health care

welfare cost and health insurance a disaggregated approach using duality theory and australian data the present study draws on the fundamental duality between consumer expenditure and utility to provide a hicksian measure of the welfare cost or moral hazard arising from health insurance in australia the theoretical approach is empirically applied to a homogeneous set of medical services associated with diagnosis of the upper gastrointestinal tract viz barium meal radiology the empirical results indicate that the welfare loss represents 1 3 of the total expenditures and 1 5 of the health insurance rebates on barium meal radiology for the year 1984 85 sensitivity analysis indicates that the welfare loss in relatively invariant to changes in the coinsurance rate when the latter takes on values of less than 0 5

exploring the existence of kuznets curve in countries environmental efficiency using dea window analysis abstract this paper using data envelopment dea window analysis and generalized method of moments gmm estimators examines the existence of a kuznets type relationship between countries environmental efficiency and national income specifically it measures the environmental efficiency of 17 oecd countries by constructing environmental efficiency ratios for the time period 1980 2002 the analysis with the application of dynamic panel data reveals that there isn t a kuznets type relationship between environmental efficiency and income allowing for dynamic effects we find that the adjustment to the target ratio is instantaneous we also find that increased economic activity does not always ensure environmental protection and thus the path of growth is important in addition to the growth itself

variable organizational risk preferences tests of the march shapira model march and shapira s 1987 1992 model of managers risk preferences allows for shifts in attention between survival and aspiration levels our study provides initial empirical tests of their model

weak disposability in nonparametric production analysis with undesirable outputs environmental economics and natural resources group at wageningen university in the netherlands weak disposability of outputs means that firms can abate harmful emissions by decreasing the activity level modeling weak disposability in nonparametric production analysis has caused some confusion this article identifies a dilemma in these approaches conventional formulations implicitly and unintentionally assume all firms apply uniform abatement factors however it is usually cost effective to abate emissions in those firms where the marginal abatement costs are lowest this article presents a simple formulation of weak disposability that allows for non uniform abatement factors and preserves the linear structure of the model

physician response to fee changes with multiple payers this paper develops a general model of physician behavior with demand inducement encompassing the two benchmark cases of profit maximization and target income behavior it is shown that when income effects are absent physicians maximize profits and when income effects are very strong physicians seek a target income the model is used to derive own and cross price expressions for the response of physicians to fee changes in the realistic context of more than one payer under the alternative behavior assumptions of profit maximization and target income behavior the implications for public and private fee policy and empirical research on physician response to fees are discussed

the normative economics of health care finance and provision whereas in many countries the crisis in medical care has been seen in terms of excess spending on health services in the uk it has been seen at least by most of those who manage and work in the nhs as a crisis of underfunding this has come about as the result of the government s successful attempts to restrain the rate of growth of real spending on the nhs which in turn reflects the government s belief that its principal effective weapon against what it perceives to be inefficiency in the nhs is to challenge management itself reformed and to some extent liberated by systematic financial squeezes the same concern has given rise to a host of proposals for reform of the nhs most of which involve a much greater role for private insurance private finance of other kinds such as out of pocket payments and private provision of health care itself

a behavioral resource based view of the firm the synergy of cyert and march 1963 and penrose 1959 cyert and march s 1963 seminal behavioral theory is one of the two major economics based theories of the firm that goes inside the black box the firm the other being the contribution of edith penrose the two theories have differences but also similarities and substantial scope for cross fertilization that has gone unnoticed in the literature in this paper we try to integrate important ideas from both books paying particular attention to the issue of excess resources slack and intrafirm conflict we then build on the integrated framework by delving into the nature of intrafirm conflict and its relationship to the degree of intrafirm rivalry as they may impact the possible use of slack by firms we derive propositions common to the two theories and new ones of importance to our understanding of organizational growth and change

a behavioral theory of market expansion based on the opportunity prospects rule what explains organizational search and choice when multiple opportunities are available to the decision makers drawing on the behavioral view of the firm and on the attention based view this study proposes a theoretical model centered on the opportunity prospects rule to explain market expansion defined as the extent how many and the selection which of multiple available opportunities that are actually pursued by competing firms we test our model using longitudinal fine grained data on commercial banks undertaking more than 1 300 opportunity choices the findings show that firms do use the opportunity prospects rule when exercising market expansion choices and that slack and performance feedback moderate the effects of opportunity prospects this paper contributes to organizational decision making research and to the behavioral view of the firm by showing the importance of considering an opportunity driven approach by demonstrating the relevance of simplifying rules to explain the search for the consequences of alternatives by extending recent efforts to provide a more forward looking perspective to model organization behavior and by showing when slack and performance feedback moderate the effects on market expansion of the opportunity prospects rule

is there an environmental kuznets curve for sulfur abstract most existing estimates of the environmental kuznets curve ekc for sulfur which use samples of mainly high income countries indicate a maximum emissions turning point at middle to lower high income levels of gdp per capita we use a larger and more globally representative sample than previous sulfur ekc studies we find that sulfur emissions per capita are a monotonic function of income per capita when we use a global sample and an inverted u shape function of income when we use a sample of high income countries a model estimated in first differences results in a monotonic ekc when estimated with both high income and global samples reductions in emissions are time related rather than income related

the liability of good reputation a study of product recalls in the u s automobile industry in this paper we explore opposing theoretical claims about how organizational reputation affects market reactions to product defects on the one hand good reputation could be a disadvantage because expectations about product quality are more likely to be violated by defects in highly reputed products on the other hand a good reputation could be an advantage because of strong inertial effects on reputation orderings we empirically test these competing hypotheses using data on product recalls in the u s automobile industry from 1975 to 1999 our results support for the idea that reputation can be an organizational liability in that highly reputed firms suffer more market penalty as a result of their product recalls we also propose that the reputational effects are moderated by two important factors substitutability and generalism specialism our results show that having few substitutes with an equivalent level of reputation or a focused product identity stemming from specialism buffers the negative market reactions to product recalls we conclude with a discussion on the implications of these results for institutional reputation and status theories
