manufacturing investment and taxation in the nordic countries the accumulation of fixed productive capital in the manufacturing industries of denmark finland norway and sweden is analyzed for the period 1965 90 particular attention is given to the effect of taxes on this process the following conclusions appear fairly robust across countries cointegrating long run relationships can be found within the framework of the neoclassical model the error correction estimations indicate that investment is relatively sensitive to economic shocks and taxes do not seem to have had significant effects on either long run capital levels or the timing of investment copyright 1994 by the editors of the scandinavian journal of economics

regional inequalities in europe have they really been decreasing inequalities within the european community are analysed both at the national and the regional level from 1984 to 1988 based on the per capita income levels some convergence has been occurring amoung ec national economies however some regions seem to have been carrying the burden of closing the gap among nations performances the role of migration is analysed in some countries migration has been a factor tending to disguise the tendencies going on thereby promoting a misleading idea of regional convergence

conceptual framework for regional competitiveness budd l and hirmis a k 2004 conceptual framework for regional competitiveness regional studies38 1007 1020 the concept of territorial competitiveness has gained ground in academic policy and practitioner circles in particular urban competitiveness has generated a large literature however there is a danger that competitiveness at a territorial level becomes a conceptual chimera the essential problem is that territorially based actors and agencies seek to position and maintain the utility of their regions and subregions by reference to a set of measures and indicators that are conceptually suspect and often empirically weak the degree to which regions compete depends on a manifold set of factors the paper proposes a conceptual framework for regional competitiveness based on combining the competitive advantage of firms and the comparative advantage of a regional economy the conceptual transmission mechanism to regional competitiveness combines liebenstein s theory of x inefficiency and aggl

multi factor performance measure model with an application to fortune 500 companies abstract the paper develops tools for reconciling diverse measures which characterize the financial performance of the fortune 500 companies the technology of data envelopment analysis dea is employed to determine a multi factor financial performance model which inherently recognizes tradeoffs among various financial measures this study offers an alternative perspective and characterization on the performance of the fortune 500 companies it is shown that the top ranked companies by revenue do not necessarily have top ranked performance viewed as being multidimensional only about 3 companies were operating on the best practice frontier substantial technical and scale inefficiencies are found decreasing returns to scale drs are uncovered among the relatively large revenue top ranked companies the study of congestion shows that a reduction in current levels of employees assets and equity may actually increase revenue and profit levels factor specific measures within the framework of multidimensional measure are developed to further study the performance of companies and industries the performance of best practice frontier companies is analyzed by constructing reference share measures which indicate the role each frontier company plays in evaluating non frontier companies finally the reliability of the best practice frontier is examined

goal programming data envelopment analysis godea for target based multi level planning allocating central grants to the greek local authorities abstract in this paper we develop an interface between goal programming and data envelopment analysis godea in order to integrate target setting and resource allocation in multi level planning problems data envelopment analysis dea has been traditionally used for assessing the performance of individual decision making units and therefore necessary extensions are needed to apply dea principles to the global organisational level without however losing its attractive features the method was originally developed as an aid to the reorganisation of the allocation of central funds to local authorities in greece

the impact of subsidies on x efficiency in ldc industry theory and an empirical test the x inefficiency costs of protection and industrial concentration have been topics of considerable interest in the literature on economic development balassa 1975 and bergsman 1974 for example have argued that protection by increasing x inefficiency generates a major welfare cost which is not captured by traditional costs of protection calculations and white 1976 has examined the relationship between inappropriate factor intensities which he associates with xinefficiency and industrial concentration the common theme which emerges from each of these studies is that public policy can have a major impact on economic performance not only by influencing factor proportions but also by influencing the intensity with which a non measurable input x efficiency is employed despite the intuitive appeal of the x efficiency concept there have been very few empirical tests of this hypothesis this partly reflects the imprecise nature of the basic concept but also the lack of adequate micro economic data x efficiency clearly relates to efficiency within firms so that the most appropriate tests would rely on data on firm level efficiency in this paper we propose a direct test of the x efficiency hypothesis using firm level data we build on previous work by corden 1970 1974 and martin 1978 who showed how to model x efficiency effects using the concept of managerial leisure we extend these simple models of managerial behavior emphasizing the role of the external managerial labor market the model is then used to explore the relationship between changes in public policy managerial effort and x inefficiency certain predictions of the model are tested using cross section data from a survey of firms in two subsidized industries in ghana efficiency indices are computed on the basis of a translog frontier production function variations in relative efficiency are then correlated with several explanatory variables including the presence or absence of subsidy payments to the firm subsidized firms in both industries are found to exhibit higher relative levels of x inefficiency

profit incentives and technical efficiency in the production of nursing home care in recent years nursing home care expenditures have approached one percent of gnp their growth is a major contributor to the escalating costs of health care in this article the authors analyze a sample of nursing homes from wisconsin to determine the characteristics of the efficiently operated nursing homes data envelopment analysis is used to calculate efficiency scores for the various nursing homes in the sample the authors then use regression analysis to investigate the determinants of efficiency holding constant the characteristics of the output they find that for profit firms have significantly higher efficiency scores copyright 1989 by mit press

resource allocation based on efficiency analysis the purpose of this paper is to develop an approach to a resource allocation problem that typically appears in organizations with a centralized decision making environment for example supermarket chains banks and universities the central unit is assumed to be interested in maximizing the total amount of outputs produced by the individual units by allocating available resources to them we will develop an interactive formal approach based on data envelopment analysis dea and multiple objective linear programming molp to find the most preferred allocation plan the units are assumed to be able to modify their production in the current production possibility set within certain assumptions various assumptions are considered concerning returns to scale and the ability of each unit to modify its production plan numerical examples are used to illustrate the approach

measuring technical efficiency abstract the theoretical consideration of technical efficiency has existed since koopmans koopmans t c 1951 an analysis of production as an efficient combination of activities in koopmans t c ed activity analysis of production and allocation cowles commission for research in economics monograph no 13 wiley new york defined it as production possibilities for which it is not possible to increase any output without simultaneously increasing any input ceteris paribus the non parametric approach to efficiency calculation known as data envelopment analysis is not based on this definition but rather on the radial index of farrell farrell m j 1957 the measurement of productive efficiency journal of the royal statistic society ser a 120 253 281 even after farrell efficiency is achieved there may exist additional slack in individual inputs and or outputs implying that farrell s index does not necessarily measure koopmans inefficiency various measures have been proposed to solve this problem this paper discusses shortcomings of these alternative measures and introduces a new relative measure of technical efficiency using simulated data it is shown that the new measure outperforms existing measures in the majority of cases

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

exchange market pressure in paraguay 1963 88 monetary disequilibrium versus global and regional dependency the relevance of the monetary approach to exchange market pressure for paraguay s small open economy is compared to that of two competing keynesian structural approaches which emphasize respectively global and regional dependency effects estimation results for the three models including formal comparisons using nonnested hypothesis tests and forecast accuracy staistics suggest that the explanatory power of the monetary model is dominated by that of the regional dependency model with the global dependency model having an intermediate degree of applicability this result is intuitive given the extreme dependency of the paraguayan economy on argentina and brazil

the structure of technical efficiency it is common practice to decompose measures of efficiency into component measures of technical and allocative efficiency in this paper we show how and why to decompose a general measure of technical efficiency into component measures of purely technical efficiency congestion and scale efficiency and we investigate the properties of each measure we do so for a multiple output technology which satisfies a weak axiom system that does not include either constant returns to scale or strong input disposability

technical efficiency shadow price and substitutability of chinese industrial so2 emissions a parametric approach abstract in china s transition process towards sustainable development fighting against the rising so2 emission has become a great and urgent challenge based on a parametric quadratic directional distance function this paper investigates the inefficiency level shadow price and substitution elasticity of chinese industrial so2 emission from 1998 to 2011 the results show a u shape for the technical inefficiency indicating an efficiency improvement before 2005 but it getting worse since then which is that the east area displays a declining trend while the west goes up and the middle follows the national pattern at the east middle west region level as of the shadow price and morishima elasticity both the national and regional levels hold an increasing trajectory the shadow price is continuously increased a lot during the whole period implying to control additional so2 emission become more costly the positive morishima substitution elasticity suggests there may exist the win win opportunities for so2 regulation moreover the large regional disparity highlights the needs to adopt a differentiated regional policy

efficient resource allocation via efficiency bootstraps an application to r d project budgeting resource allocation decisions are crucial for the success of an organization this paper proposes an integrated approach to resource allocation problems in which decision makers have one observation of the multiple input output criteria of candidates we offer important improvements over existing approaches based on the widely used data envelopment analysis dea which has two major limitations in its application to resource allocation first traditional dea models compute efficiency scores by optimizing firm specific shadow prices of inputs and outputs this could be problematic because in practice stakeholders would usually require unanimously agreed upon trade offs among evaluation criteria second previous allocation approaches based on dea do not allow for controlling the risk exposure of allocation portfolios to tackle these problems we propose an efficiency measure based on equilibrium shadow prices of different criteria and we use the bootstrap efficiency distributions to gather information regarding efficiency variations and correlations through our methodology decision makers can obtain the risk minimizing allocation portfolio we illustrate the proposed approach through an empirical r d project budgeting problem in which we allocate funding according to the projects efficiency distributions

european integration and local capacities for manufacturing adjustment and change the case of spain the southward enlargement of the european community with the full accession of spain and portugal in 1986 and the creation of the single market in 1993 have opened up new opportunities for exports to the eu and have intensified competition with spanish made products in the rest of the eu this paper hypothesises that local adjustment to european integration is conditioned by the comparative local advantages or disadvantages in human resources nodality and external economies which can shape local capacity for the achievement of economies of scale in production technological modernisation the development of small and medium enterprises smes and business services the capacities for these four dynamic processes are articulated through the interaction between the investment decisions of spanish and foreign owned firms and the local comparative advantages and hence influence the capacity of localities to respond to european integration through trade creation and trade diversion

regional wage differentials and the spatial convergence of worker characteristic prices this paper provides a test for variation in wage structures across regions the authors suggest that the appropriate test for structural variation incorporates a combination of two lines of research structural variation and compensating variation the model of earnings determination used implies that while job characteristic prices may be subject to stochastic shocks or industry specific factors and hence may differ between regions the returns to human capital characteristics will be regionally invariant the results suggest that the theoretical expectations of regional homogeneity is generally supported for the decade of the 1970s copyright 1989 by mit press

declining city productivity and the growth of rural regions a test of alternative explanations prior to the 1970s the u s witnessed a net flow of migrants from its nonmetropolitan to its metropolitan region since then however a dramatic reversal of this long standing tendency for people to concentrate in metropolitan places has been observed nonmetropolitan places have gained migrants largely as the result of increased outmigration from metropolitan areas an open question has been to what extent the employment profile between metropolitan and nonmetropolitan places parallels that of population this paper introduces a data series compiled from county business patterns that is used to analyze the employment trends for the first time the analysis reveals that not only is total employment growing fastest in nonmetropolitan counties but it also appears that the turnaround in employment growth preceded the reversal in the rate of population increase manufacturing which had faster nonmetropolitan growth rates even during the 195os appears to have led in the development of nonmetropolitan counties this shift of manufacturing has attracted other sectors as well as people to nonmetropolitan places part of the recent growth of nonmetropolitan counties represented nothing more than a continuation of suburbanization or spillover of people and jobs which permitted one more outward bound into adjacent nonmetropolitan counties but there is more to nonmetropolitan development than simply metropolitan spillover nonmetropolitan counties far removed from metropolitan ones are also growing faster than metropolitan counties it is shown that this rural renaissance is part of a general deconcentration

tariff structure of japanese electric power companies an empirical analysis using dea this research explores a marginal cost mc based pricing system using data envelopment analysis dea this dea technique is widely applied for performance analysis and efficiency measurement in public and private sectors this article does not follow such a previous research direction rather directing itself towards the new measurement of mc and ramsey prices of multiple electric power services as an important case study this research applies the proposed dea approach to examine how much the current tariffs of japanese electric power services deviate from these mc and ramsey prices this type of research has never been explored in japan even though such a research effort is needed by many policy makers and consumers it is hoped that our empirical findings can serve as a policy making basis for guiding the japanese electric power industry this study believes that this japanese experience is useful for other nations such as asia pacific countries where many public industries are regulated by their governments

technical efficiency and economies of scale in state owned enterprises the hellenic telecommunications organisation abstract in this paper we propose methodologies for assessing the relative efficiency of state owned enterprises that operate under monopolistic conditions irrespective of the ownership structure private or public monopolistic operation is often given unclear conflicting operating objectives by their principals or regulators and thus efficiency should be assessed using alternative objectives such as cost production and revenue on the methodological side the paper employs parametric functional forms using ordinary least squares and goal programming methods of estimation a secondary estimation stage was also pursued with the input output variables of the models being corrected for technical inefficiency the methodology was applied to examine the technical efficiency and economies of scale of the hellenic telecommunications organisation over the period 1971 1993

cost efficiency of french rugby clubs this article analyses the cost efficiency of french first league rugby clubs using a stochastic frontier model the frontier estimation confirmed that the model fits the data well with all coefficients correctly signed and in line with the theoretical requirements the results show that one of the clubs is operating efficiently with the majority of clubs clustered around 20 inefficiency policy implications are derived

divestiture of nippon telegraph and telephone this article discusses whether the japanese government should break up ntt nippon telegraph telephone in 1995 as the u s federal government compelled at t american telephone telegram to break itself into toll and local telephone companies in 1984 the divestiture of ntt has long been a major industrial policy issue in japan since the common carrier was privatized in 1985 the governmental decision to divest it may influence not only the japanese telecommunications infrastructure but also the global telecommunications and information industries in the world where many common carriers are now facing an environmental change from regulation to competition a unique feature of this study is that it employs eight different estimation techniques to obtain a cost function of ntt so that this research avoids a methodological bias occurring in many empirical studies this study confirms that ntt has maintained cost subadditivity but it has failed to establish the status of a natural monopoly in the observed time period however it also finds that the ntt divestiture will not produce a price reducing benefit to japanese telecommunications consumers this research result will serve as empirical evidence for guiding the governmental review of this large scale industrial policy issue in japan

economic efficiency of greek retail smes in a period of high fluctuations in economic activity a dea approach this study aims to analyse the economic efficiency of greek small and medium retail enterprises before and after the crisis that started in 2008 based on the accounting equation we use data envelopment analysis dea to estimate variable returns of scale efficiency scores and to conclude on specific characteristics that efficient companies have for example on capital structure our results from the dea application show a high degree of inefficiency we found that smes on the islands are more efficient than those on the mainland and that smes in the cities are the least efficient size seems to be important more so on the islands and on the mainland than in the cities we conclude that companies should act more conservatively in terms of operating cost when the first signs of a recession appear in addition during a recession period companies that have evidences that their operations will continue positively should strengthen their operations by raising more own capital finally our study clarifies

hypercongestion in production correspondences an empirical exploration this empirical contribution reviews the rather limited existing literature measuring congestion in production it first compares current ways to measure congestion using nonparametric specifications of technologies in particular it focuses on the magnitude and incidence of the congestion detected in empirical studies using traditional radial efficiency measures thereafter it shows the limitations of this radial measurement and how alternative measurement schemes may reveal higher amounts of congestion then the new more general methodology of measuring s congestion is presented in particular we first present a numerical example to illustrate the way the s disposable technologies allow to capture more extreme forms of congestion by setting empirically determined upper bounds to the wasting of inputs then an empirical illustration is presented based on an existing sample of data a final section concludes

privatization of nippon telegraph and telephone was it a good policy decision nippon telegraph and telephone ntt corporation was privatized in 1985 under the economic assertion that a public enterprise is less efficient and less profitable than a private enterprise this assertion is referred to as the property right theory in economics and it is used as a theoretical rationale for privatizing publicly owned organizations this article empirically examines the economic assertion by comparing ntt s performance before and after its privatization data envelopment analysis dea is used as the research tool in this study which confirmed the economic assertion in terms of production based efficiency measures but it cannot find any major difference in its cost reducing corporate efforts thus this study presents serious management problems occurring within the ntt s partial privatization the partial privatization is now prevailing in the telecommunications industry all over the world this article also discusses the japanese business environment which makes ntt managerially ineffective under its public private joint ownership

capital adjustment patterns in swedish manufacturing firms what model do they suggest in this paper we study the capital adjustment process in swedish manufacturing firms and relate the empirical findings to standard models of firm behavior in the presence of impediments to capital adjustments we find that i a model with irreversible capital goes a very long way in capturing the salient features of firm level capital adjustment behavior to see this an integrated approach is necessary since different alternative models do well in certain comparative dimensions but not in others ii the partial adjustment model generally fails to explain capital adjustment patterns iii the capital accumulation process is a highly volatile and non persistent process on the firm level iv firms adjustment behavior is asymmetric in that they are more likely to tolerate excess capital than shortages of capital and finally v the estimated adjustment function implies that aggregate investment is relatively unresponsive to aggregate shocks in deep recessions as compared to the responsiveness in normal times

fixed cost and resource allocation based on dea cross efficiency abstract in many managerial applications situations frequently occur when a fixed cost is used in constructing the common platform of an organization and needs to be shared by all related entities or decision making units dmus it is of vital importance to allocate such a cost across dmus where there is competition for resources data envelopment analysis dea has been successfully used in cost and resource allocation problems whether it is a cost or resource allocation issue one needs to consider both the competitive and cooperative situation existing among dmus in addition to maintaining or improving efficiency the current paper uses the cross efficiency concept in dea to approach cost and resource allocation problems because dea cross efficiency uses the concept of peer appraisal it is a very reasonable and appropriate mechanism for allocating a shared resource cost it is shown that our proposed iterative approach is always feasible and ensures that all dmus become efficient after the fixed cost is allocated as an additional input measure the cross efficiency dea based iterative method is further extended into a resource allocation setting to achieve maximization in the aggregated output change by distributing available resources such allocations for fixed costs and resources are more acceptable to the players involved because the allocation results are jointly determined by all dmus rather than a specific one the proposed approaches are demonstrated using an existing data set that has been applied in similar studies

the advantage of tying one s hands ems discipline and central bank credibility abstract it is often argued that the ems is an effective disciplinary device for inflation prone countries in europe since it forces the respective policy makers to pursue more restrictive monetary policies than they would otherwise it is not clear however why these countries should submit themselves to such discipline this paper argues that to answer this question appropriately one must consider that ems membership brings potentially large credibility gains policy makers in inflation prone countries the reason is that not only it attaches an extra penalty to inflation in terms of real appreciation but makes the public aware that the policy maker is faced with such penalty and thus helps to overcome the inefficiency stemming from the public s mistrust of the authorities

technical scale and allocative efficiencies in u s banking an empirical investigation a nonparametric frontier approach is used to calculate the overall technical pure technical allocative and scale efficiencies for a sample of 322 independent banks the sample was drawn from the federal deposit insurance corporation tapes on the reports of condition and reports of income call reports for the year 1986 the results indicated a low level of overall efficiency the main source of inefficiency was technical in nature rather than allocative separate efficiency frontiers were constructed to test the effect of branching however the distributions of efficiency measures for branching and non branching banks were not found to be different

china s regional natural resource allocation and utilization a dea based approach in a big data environment abstract china s economic reform and opening policy has resulted in china s rapid growth especially in terms of economy the growth however is mainly based on huge consumption of natural resources and that consumption should be reduced by significant amounts to protect global ecosystems emerged in 1980s big data has developed very quickly in recent years bringing new perspectives and opportunities for all kinds of academic fields especially in dea since it is a research highly based on data in this paper we propose a sbm dea model based on natural resource input orientation to evaluate the efficiency of natural resource utilization for 26 provincial regions in mainland china from 2005 to 2012 a dea based approach is developed to allocate a reduced total of natural resources among the 26 provincial regions drawing support from the developments of big data we use each provincial region s previously observed production data to characterize its own production technology which allows a better analysis of how the production will change after allocations of natural resources are reduced our empirical study shows that most provincial regions perform well in terms of efficiency in utilizing natural resources but that is based on huge consumption of natural resources from an area perspective the eastern area of china achieved the highest average efficiency value followed by the central and western areas our study also indicates that the most effective allocation of the natural resources requires about half of the 26 provincial regions to reduce their natural resource consumption while the remaining ones can maintain their original consumption

allocating fixed costs and resources via data envelopment analysis abstract in this paper we show that data envelopment analysis dea can be viewed as maximising the average efficiency of the decision making units dmus in an organisation building upon this we present dea based models for a allocating fixed costs to dmus and b allocating input resources to dmus simultaneous to allocating input resources output targets are also decided for each dmu numeric results are presented for a number of example problems taken from the literature

external shocks and fiscal deficits in a monetary model of international reserve determination honduras 1960 83 results from single equation estimation of a standard monetary model suggest that central bank credit growth in excess of growth of money demand was the main source of international reserve losses in honduras during the 1960 83 period further 3 sls estimates suggest that increases in central bank credit growth were largely in response to rising external interest rates and decreases in the income terms of trade in addition income growth hence growth of money demand shows a strong positive response to the income terms of trade the fiscal deficit is found to have an insignificant impact on central bank credit growth

a dynamic multi stage data envelopment analysis model with application to energy consumption in the cotton industry abstract data envelopment analysis dea is a non parametric method for evaluating the relative efficiency of homogenous decision making units dmus with multiple inputs and outputs in this paper we present a dynamic multi stage dea dms dea approach to evaluate the efficiency of cotton production energy consumption in the proposed model the farms which consume resources i e fertilizers seeds and pesticides to produce cotton are assumed to be the dmus inputs not consumed during a planning period are carried over to the next period in the planning horizon initially a dms dea model is used to determine the overall efficiency of the dmus with dynamic inputs next the efficiency score of each dmu is calculated for each time period in the planning horizon we demonstrate the applicability of the proposed method and exhibit the efficacy of the procedures and algorithms with a real life case study of energy consumption in the cotton industry

a dea based incentives system for centrally managed multi unit organisations in multi unit organisations such as a bank and its branches or a national body delivering publicly funded health or education services through local operating units the need arises to incentivize the units to operate efficiently in such instances it is generally accepted that units found to be inefficient can be encouraged to make efficiency savings however units which are found to be efficient need to be incentivized in a different manner it has been suggested that efficient units could be incentivized by some reward compatible with the level to which their attainment exceeds that of the best of the rest normally referred to as super efficiency a recent approach to this issue varmaz et al 2013 has used data envelopment analysis dea models to measure the super efficiency of the whole system of operating units with and without the involvement of each unit in turn in order to provide incentives we identify shortcomings in this approach and use it as a starting point to develop a new dea based system for incentivizing operating units to operate efficiently for the benefit of the aggregate system of units data from a small german retail bank is used to illustrate our method

regional concentration and efficiency in mexican manufacturing abstract this paper explores the link between industrial location concentration and economic efficiency in mexican manufacturing using a linear programming approach the authors calculate indices of overall technical allocative and scale efficiency for mexican manufacturing industries by state to test whether in 1985 those regions with high levels of industrial concentration were suffering from the costs of congestion the evidence suggests that at least at the aggregate level there continued to be a positive relationship between industry concentration and efficiency in production there is also evidence that overall efficiency was related to scale efficiency although highly industrialized regions on the production frontier often operated at inefficient scales in particular the most concentrated regions the federal district the state of mexico jalisco and nuevo leon consistently display decreasing returns to scale indicating that the process of industrial concentration may be leading to diseconomies of scale finally an econometric analysis suggests that scale urbanization and agglomeration economies are positively related to overall and technical efficiency at the regional level while foreign ownership is negatively related agglomeration economies at the industry level were not significant the paper also makes a methodological contribution it is the first application of a distance function production methodology to measuring regional efficiency in a developing country it demonstrates how to conduct distance function efficiency analysis using the newly developed gams mathematical programming environment these tools should be of considerable interest to applied microeconomists

assessment of china transit and economic efficiencies in a modified value chains dea model abstract this study incorporates the concepts of undesirable intermediate intermediate input uncontrollable input and undesirable output to the value chains model chen and zhu 2004 thereby creating a modified value chains model to compute transit and economic efficiencies in 30 regions of china the modified value chains model forms a more general formulation to the value added chains in the utilization of the above concepts it also provides an optimal intermediate measure which differs from the independent two stage measure empirical evaluations indicate that large scale transit development in china s coastal area does not necessarily represent higher transit efficiency because in the coastal area there is a lack of significant positive relationships between transit and economic efficiency high economic efficiency does not contribute to greater transit efficiency the finding also suggests that by simultaneously decreasing the quantity in passenger and freight transport transit and economic efficiencies have greatly improved in most regions of china

using dea to evaluate 29 canadian textile companies considering returns to scale in this research we use data envelopment analysis dea to evaluate the performance of 29 canadian textile companies in 1994 using the charnes cooper and rodes ccr model in dea we first obtain the results of efficiency scores and returns to scale of 29 canadian textile companies we then focus on the returns to scale to examine the possibility of utilizing the inefficient inputs by either further expansion or vertical integration we develop a mathematical model to consider the trade off between reducing and not reducing the input surplus we use the cone ratio model to find the optimal level of vertical utilization the computational results are based on real data from the canadian textile companies

exchange market pressure in postwar brazil an application of the girton roper monetary model this study applies lance girton and don roper s hereafter g r monetary model of exchange market pressure to the postwar brazilian monetary experience the model was designed specifically for the canadian managed float during the period 1952 62 the object of their model is to explain what they term exchange market pressure that is the pressure on foreign exchange reserves and the exchange rate when there exists an excess of domestic money supply over money demand in a managed floating exchange rate regime the basic theoretical proposition is that any such excess supply of money can be relieved by an exchange depreciation a loss in foreign reserves or in the context of a managed float by some combination of the two in this sense the g r managed float model used here is firmly rooted in the modern monetary approach to exchange rates and the balance of payments brazil provides a particularly good example for testing this approach not only because it is in many senses a unique example of a postwar managed float system but also because it can be treated as a small open economy in the sense that world prices and monetary conditions faced by brazil are taken as given this particularly suits the purpose of most modern monetary models which make this assumption and obviates the problems of monetary dependence and neutralization dealt with in the pioneering g r paper specifically the small country assumption permits us to devise a simple one country equation of managed floating which depends upon four essential ingredients 1 money demand 2 money supply 3 purchasing power parity and 4 monetary equilibrium 2 furthermore in brazil a much greater proportion of exchange market pressure was absorbed by exchange rate depreciation than in the canadian case where changes in reserves were large relative to exchange rate movements in short postwar brazil provides a singularly good opportunity to test the monetary model of exchange market pressure section i briefly states the essential elements of the monetary model and derives the equation to be tested for the brazilian experience from 1955 to 1975 section ii reports empirical results for the exchange market pressure model and section iii examines the applicability of the relative version of purchasing power parity for the time period considered section iv summarizes the results and discusses the merits of the monetary approach in light of the brazilian experience

assessing eco efficiency through the dea analysis and decoupling index in the latin america countries abstract this study was developed according to a two step approach in the first step we provide an investigation of the changes in eco efficiency under constant and variable return to scale while on a second step the evaluation of the decoupling elasticity will be given the impacts of energy economic and environmental determinants inputs on the performance indicators of eco efficiency were calculated as the inverse of the carbon intensity ratio of the gdp over the co2 emissions both from the world development indicators database the changes in eco efficiency and the decoupling elasticity between co2 emissions and economic growth changes data was used for 16 latin america countries according to five year periods from 1994 to 2013 for all the five time span considered it is worth noting that the degree of technical efficiency for the latin america countries is lower than the degree of technological efficiency thus indicating that a portion of the overall inefficiency is due to the fact that these countries are producing below the production frontier rather than to an inefficient use of technology on average the results have confirmed that the technological scale change in energy production is the dominant factor influencing the optimal production frontier in the sample of countries under analysis complementarily according to the mixed results from the decoupling analysis we may conclude that the increase decrease of the co2 per capita emissions was due to other economic and environmental factors rather than to a negative positive effect of the gdp growth rate

the measurement of productive efficiency a reconsideration the purpose of this paper is to generalize the farrell indexes of productive efficiency to nonhomothetic production technologies and at the same time maintain the cost interpretation of the farrell measures since the generalized indexes rely heavily on recent developments in the estimation of frontier cost and production functions several frontier models are reviewed in addition to generalized indexes of technical allocative and overall productive efficiency a variety of single factor efficiency measures are discussed the applicability of the proposed efficiency measures is illustrated with a numerical example of electric power generation

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

a goal programming constrained regression review of the bell system breakup the recently implemented court decision to break up bell american telephone telegraph co to accord with u s anti trust laws represents a highly significant policy decision which is proving to be influential in other countries as well as the u s the telecommunication industry is of such size and importance that even relatively small economies that might be lost with bell s breakup as a natural monopoly could involve substantial welfare losses to consumers and producers studies commissioned by the u s justice department that approached this topic by econometric methods reported that the evidence failed to support the contention that bell was a natural monopoly here a goal programming constrained regression as developed in the management science literature uses the same functional form and the same data but nevertheless reverses the main findings of the econometric studies in every one of the 20 years covered this kind of difference in results obtained by two different methods of analysis poi

restricted reallocation of resources abstract this paper investigates restricted reallocation among individual units when the efficiency index is calculated for an aggregated unit in the dea framework moreover we address the question of the optimal reallocation flow the optimal flow of inputs among the individual units subject to given transfer costs restrictions on reallocation can be given by the maximum cost the managers are willing to pay in the framework of full reallocation there is a trade off between the maximum allowed reallocation cost and the highest efficiency the aggregated unit can achieve the final goal is to present a way to generate efficiency gain functions that show this trade off

the regional impact of infrastructure investment in mexico looney r and frederiksen p 1981 the regional impact of infrastructure investment in mexico reg studies 15 285 296 using multiple regression analysis production functions are estimated for mexico to examine whether infrastructure s impact on gdp differs depending on the type of investment economic or social overhead capital or the type of recipient region intermediate or lagging this possibility has been suggested by hansen the states were grouped by means of cluster analysis the results tend to confirm the hansen thesis economic overhead capital has had its greatest impact on gdp in intermediate regions while social overhead capital has had its greatest impact in lagging regions a test for causality indicates that investment precedes income growth several policy recommendations are offered on the basis of these results

measuring technical efficiency and productivity growth a comparison of sfa and dea on norwegian grain production data this article compares data envelopment analysis and stochastic frontier analysis to assess efficiency and productivity growth of norwegian grain producers previous studies have dealt with either one of them and less of both for the assessment of productivity growth or regress malmquist productivity indices are derived from both approaches the data cover a 10 year period we find consistency between the approaches to the extent that 1 there are potentials for efficiency improvements but the magnitudes depends on the model applied and by segmentation of the data set 2 there has been a productivity improvement in the sector on average in the interval 30 38 in the period studied and 3 technical change has had the greatest impact on productivity indicating that producers have a tendency to catch up with the front runners in general policy makers are warned not to be indifferent with respect to the approach used for efficiency and productivity measurement as these may give different results

assessing the technical and allocative efficiency of hospital operations in greece and its resource allocation implications abstract in this paper we seek to develop a research framework concerning the assessment of the efficiency of public sector hospital operations public hospitals are increasingly under pressure to improve their operations both in terms of resources they use and also in terms of the quantity and quality of their outcomes the assessment of efficiency entails both the notions of technical and allocative efficiency as they yield complementary information about the management effectiveness of individual hospitals technical efficiency has a diagnostic purpose as it yields comparative information about the effectiveness with which individual units convert their input resources into outputs on the other hand allocative efficiency has a planning orientation since the objective of the assessment is to gauge efficiency improvements by means of resource reallocation a linear programming based model is proposed for assessing allocative efficiency in the light of uncertainty about the prices of input factors the empirical part of the paper is based on data from greek public hospitals results and policy implications are discussed based on data from 98 general hospitals based on information from 1992 it was found that significant inefficiencies are present in the operations of greek hospitals that account approximately for 100 mecu in 1992 prices
