This paper presents a metafrontier production function model for firms in different groups having different technologies. The metafrontier model enables the calculation of comparable technical efficiencies for firms operating under different technologies. The model also enables the technology gaps to be estimated for firms under different technologies relative to the potential technology available to the industry as a whole. The metafrontier model is applied in the analysis of panel data on garment firms in five different regions of Indonesia, assuming that the regional stochastic frontier production function models have technical inefficiency effects with the time-varying structure proposed by Battese and Coelli (1992).  相似文献

This paper proposes an econometric framework for joint estimation of technology and technology choice/adoption decision. The procedure takes into account the endogeneity of technology choice, which is likely to depend on inefficiency. Similarly, output from each technology depends on inefficiency. The effect of the dual role of inefficiency is estimated using a single-step maximum likelihood method. The proposed model is applied to a sample of conventional and organic dairy farms in Finland. The main findings are: the conventional technology is more productive, ceteris paribus; organic farms are, on average, less efficient technically than conventional farms; both efficiency and subsidy are found to be driving forces behind adoption of organic technology.  相似文献

This paper compares technical efficiency (TE) and metatechnology ratios (MTR) for dairy farms from Argentina, Chile and Uruguay using the meta-frontier (MF) approach. The estimated average MTRs for Argentina, Chile and Uruguay are 83.8, 79.6 and 91.4%, respectively, and these results are significantly different from each other. The TEs estimated with respect to the MF are 72.8, 65.8 and 73.4% for Argentina, Chile and Uruguay, respectively. The average TEs for Argentina and Uruguay are not significantly different from each other but are significantly higher than the value for Chile. The production frontiers for Argentina and Uruguay are relatively close to the MF, which suggests that these two countries might need to increase investments to promote local research to generate new technologies and/or search for technologies to adapt from more distant areas. By contrast, Chile could benefit from adaptive research, designed to make borrowed technology from Argentina and/or Uruguay applicable to local conditions, which could be a cost effective way to improve dairy farm performance.  相似文献

This paper uses Hungarian firm level panel data for the agricultural and light manufacturing sectors during the early years of the transition to investigate differences and changes in the efficiency of input use. Programming techniques measure scale and technical efficiency. The simple radial measure, as well as two other measures that account for programming slacks, are used. The results show little wastage of materials and labour, but inefficient use of energy and capital, which suggests that the development of input markets was uneven. The price liberalisation of 1989 widened efficiency differences, especially in agriculture, but this sector recovered quickest, actually using capital more efficiently by 1991. However, energy efficiency levels were low in the period of soft budget constraints and fell still further after the reforms, suggesting that a free market for energy was not established, particularly in agriculture.  相似文献

This study measures productivity growth on Irish dairy farms over the period 1984–2000. A total factor productivity index is constructed for the dairy system and is decomposed into technical change, efficiency change, and changes in scale efficiency. This is achieved by estimating a stochastic output distance function model of the production technology in use on Irish dairy farms. Overall, productivity on Irish dairy farms grew by 1.2% per annum over the sample period.

A greater productivity level in milk production is the best answer to the increasing demand for this essential food. The main material of this study, which aims to determine the total factor productivity (TFP) and efficiency of dairy farms, consists of 100 surveys chosen from 1,429 registered farms of the Cattle Breeders Association of Aydin-Turkey by means of stratified sampling in May, 2006. The TFP decreases with farm size which shows that large farms fail to utilize their labour resource in full. In data envelopment analysis 15 farms work with an efficiency rate of 100%. The lowest efficiency rate was found to be 43%; the highest one was 100% and the mean rate was 79%. The efforts to improve efficiency levels should include participatory extension and coordinated research programs that aim to increase the productivity and efficiency levels of these small farms in the long run.  相似文献

Applying programming techniques to farm-level panel data for four cooperative and 12 private dairy farms in the Yugoslav Republic of Slovenia gives estimates of technical efficiency, scale efficiency, and technical progress. These are used to construct multilateral Malmquist indices of total factor productivity (TFP). For the cooperatives, TFP growth has been slow and is attributable to technical progress. For the private farms, technical progress was also slow, but TFP growth was faster due to improved efficiency. Scale inefficiency explains the poorer absolute performance of the private farms, indicating the need for land reform as well as technological change.  相似文献

For 52 industry sectors and 42 services sectors, this paper tests how the local economic structure (local sectoral specialization and diversity, competition, average size of plants, and total employment density) affects the 1984–1993 employment growth of 341 local areas. These areas entirely and continuously cover the French territory. The impact of the local economic structure differs in industry and services. In industrial sectors, local total employment density, competition, and plant size always reduce local growth. Sectoral specialization and diversity have a negative impact on growth, but also increase the growth of a few sectors. Service sectors always exhibit negative specialization effects and positive diversity effects. Competition and plant size have a negative impact and density a positive one, but exceptions are observed for some sectors.  相似文献

The role that the resources and capabilities of agricultural entrepreneurs play on both environmental performance (EP) and financial performance (FP) is still unclear. This study analyzes how small farms enhance EP and FP in an inland Portuguese region through the relationship between dynamic capabilities (DCs), entrepreneurial orientation (EO), and environmental sustainability commitment (ESC). Based on a sample of 160 fresh fruit farms and applying a partial least squares structural equation modeling (PLS-SEM), our study concludes that EO and ESC influence EP and FP positively. Hence, farms can achieve competitive advantage through mitigating their profound impacts on the environment as proposed by the natural resource-based view (NRBV). Farms are also improving DCs, but farmers respond to the higher environmental requirements of agricultural markets primarily through research and development (R&D) capabilities and not through marketing capabilities. Having as theoretical supports the NRBV and the DCs, our study contributes to a better understanding of the mechanisms through which entrepreneurs enhance EP and FP in sectors with high environmental impacts such as agriculture. The findings suggest that entrepreneurship training projects may enable farmers to approach food security as a market opportunity and not only as rules they must follow.  相似文献

This paper introduces a stochastic frontier production model which accommodates firm-specific temporal variation in technical inefficiency. Unlike Cornwell, Schmidt and Sickles (1990), technical inefficiency is not modeled through the intercept of the production frontier, but through an error component model. The proposed model is a generalization of the Battese and Coelli (1992) model, which imposed a common temporal pattern upon all firms. In our application involving Spanish dairy farms, we find that the new model is preferred to the Battese and Coelli (1992) model on the basis of the likelihood ratio test. Results provide a new source of information on the different patterns of technical inefficiency change among the 82 farms in the sample.  相似文献

Medication management is a complex but critical process within the healthcare delivery system. The pharmacy department in healthcare facilities is responsible for acquisition, distribution and dispensing of medication to patients that involves a series of network process. This process can be categorized into two main subprocesses: i) pharmacy store and ii) patient services (i.e., ambulatory and inpatient pharmacy). The objective of this study was to investigate the relative efficiency level of the two subprocesses of pharmacy services in Malaysia's public hospitals. We used a nonconvex metafrontier technology to estimate technical efficiency of hospital pharmacies between specialist and nonspecialist hospital categories under the dynamic network data envelopment analysis (DNDEA) framework. For overall efficiency, both specialist and nonspecialist categories had similar mean efficiency scores. However, when measuring the efficiency level according to pharmacy store and patient services separately, the nonspecialist category had a higher mean efficiency score in pharmacy store, whereas for patient service efficiency, both categories had similar results. The patient service efficiency level was lower consistently over time, suggesting that the overall inefficiency of hospital pharmacy is greatly influenced by the inefficiency of the patient service. This suggests that systematic improvements in patient service efficiency should be a higher priority than pharmacy store efficiency to further increase the overall efficiency level. We believe that our findings will provide valuable information to policymakers towards achieving an efficient public healthcare service.  相似文献

Using the stochastic metafrontier framework of Battese et al. (J Prod Anal 21:91–103, 2004), this study proposes to compare and measure the cost efficiency and cost frontier gap between the banking industry in Taiwan and China. It further identifies environmental variables that determine bank’s cost frontier gap between two countries. Data on 69 sample banks for years 2005–2009 are used in the empirical analysis and inference. The empirical results show that Taiwanese banks have in general the superior cost frontier of production, but inferior cost efficiency of operation than Chinese banks. Private banks in Taiwan have the best cost frontier, whereas foreign banks in China are most cost efficient among all banks in Taiwan and China. The empirical results also reveal that the majority of Taiwanese banks are undersized and that most banks in China are oversized. Finally, the regression results show that the financial market structure, institutional environment, and political development are significant determinants of the cost gap between the cost frontiers of banks in Taiwan and China. Therefore, programs related to changes directed toward a better bank production environment can be initiated to improve the cost technologies of banks in both Taiwan and China.  相似文献

Insofar as the completion of the Single Market for Financial Services, it has presented new challenges for European Banking industries. In this study, we use a recently developed generalized metafrontier Malmquist productivity index (gMMPI) to provide insights on productivity growth. We extend the gMMPI to broaden the index's capacity by decomposing various sources of productivity change in the metafrontier context. The sample contains commercial banks from 12 Western European countries prior to the recent financial crisis. A key advantage of our extension is that it introduces the role of scale effects. The empirical results show that an average bank's productivity growth arises mainly from technical changes and scale effects. Moreover, smaller and larger banks grow faster than medium ones. In addition, conservative banks tend to grow faster. These findings suggest that a more competitive and integrated financial market induced by financial deregulation is indeed able to improve banks’ productivity.  相似文献

A two-stage CAPM approach is used to generate cost-of-equity estimates and sources of their uncertainty for 10 GICS sectors in Canada and the U.S. under the assumption of relatively integrated North American economies and equity markets. The estimated cost of equity for the Canadian sectors is, on average, about the same as that of the U.S. sectors, but with a higher estimation error. The estimation error of the market risk premium is the most important uncertainty component for the equity cost estimates, except for Canadian Utilities where beta uncertainty is the most important component. Beta and interaction effects play a relatively more important role in Canada due to relatively more volatile sector betas in Canada. Our study suggests that: (1) Canadian cost of equity should be estimated in an integrated market rather than a segmented market and (2) higher importance should be given to estimating the dynamics of betas for the Canadian sectors.  相似文献

This study integrates metafrontier with bootstrapping to investigate automobile vehicle efficiency. The results are as follows: (1) general cars exhibited the most favorable performance in terms of price, costs, and mileage. (2) Metafrontier efficiency was the highest for general cars, which may be because this automobile type has the highest prevalence. Sports cars had the most favorable group frontier. (3) General cars had the most favorable performance in terms of miles-per-gallon. The conclusions could enhance consumers' green cognition and serve as a reference in purchase decision-making; they can provide manufacturers with directions regarding future product designs to mitigate technology gaps.  相似文献

Abstract

The aim of this study is to test the importance of entrepreneurship or new business formation for explaining differences in economic performance in the Spanish regions, together with the role played by the endowments of innovation capital and the socio-economic capabilities of every region. The results show that the effect of new business formation on economic performance varies considerably between regions, and the type of start-up is highly important for the results obtained: entrepreneur endowments of high technology intensive sectors and medium technology intensive sectors, but not those of low technology intensive sectors, have a positive effect on regional performance. Also, the size of the start-ups is important for explaining regional development.  相似文献

Since 1989, the French public sector has imitated the private sector's further education and training mechanisms. But today, it seems that just as in the private sector, the training policies in the public sector have severe limitations. Based on a case study of a large public research institute and on a national survey making it possible to compare the private and public sectors, the paper studies the further education and training policies and their links with the organizational needs. In the public sector, the difficult balance between individual's choices and strategic management comes on the one hand from the specificities of the administrative rules of human resource management, and on the other hand from the unions' power and strategies. Faced with new challenges (demographic evolutions, decentralisation, new demands from the users of public services), the French public sector must develop new training policies.  相似文献

The purpose of this paper is to assess cost dominance in direct inputs between arable crop-based systems using low or high pesticide levels per hectare. Our investigation departs from a traditional efficiency analysis and aims at comparing two minimal direct cost functions excluding pesticide expenses. This means that we evaluate the gap between two efficient frontiers instead of focusing on individual farm inefficiency scores. Our only objective is to compare two optimal cost benchmarks for systems respectively defined with high or low pesticide levels per hectare by varying their scale and output mix. A robust approach frontier is introduced to control the influence of potential outliers and unobserved heterogeneity. Based on 707 French crop farms observed in 2008, our simulations show that agricultural practices using less pesticide per hectare are unambiguously more cost-competitive in terms of direct inputs while inducing no other substitution costs. This cost dominance is a robust phenomenon regardless of the size and scope of crop activities, which supports more ecofriendly practices.  相似文献

Abstract

The study examines empirically the relationships between information technology, organisational performance, and sectors. The effects of IT on the organisational performance are evaluated with respect to generic strategic opportunities obtained from IT. This relationship and to what extent companies in the two sectors, manufacturing and service sectors, utilise these opportunities are comparatively studied. The findings of the study have shown that the effects of information technology on organisational performance and the relationship between generic strategic opportunities and organisational performance are different in the manufacturing and the service sectors.  相似文献
