Opis:: The main purpose of this publication was to try systemizing the efficiency per-formance with particular regard to technical efficiency and measurement methods, and to identify the problems in defining and measuring the existing problems. The paper presents definitions of efficiency by selected authors, the classification and characterization of vari-ous types of efficiency made with particular emphasis on technical efficiency, and the basic methods for testing the effectiveness of the division on the indicator parametric and para-metric detailing the different measurement methods. A detailed analysis of the non-parametric methods for testing the effectiveness of technical support is the DEA (Data En-velopment Analysis) method presented with the example of the procedure for calculation of relative efficiency. The study identifies various modifications of the DEA method and also signalled areas where this method can be used to measure the effectiveness of specific enti-ties. The main research method used in the present study was to review and analyze the lit-erature on the subject topic.

Opis:: The global objective of this research was determining the relations between anthropometric variables with success in judo bout. The research was conducted on a sample of 122 subjects. The sample of variables consisted of 18 anthropometric measures, out of which three latent dimensions were isolated by the use of factor analysis. Three latent dimensions (factors) represent a set of predictive variables. Criterion is defined as a success in judo bout and it is represented by two criteria variables; number of wins and technical efficiency in judo bout. To test the relations of latent anthropometric variables with success in the bout the regression analysis was used. Statistically significant but low connections were found between anthropometric variables and the two criteria. As only the factor volume and mass of the body partially contribute to the explanation of criteria, one can conclude that the active muscle mass is in the background of achieved connection.

Opis:: In the current literature, many different stochastic extensions of the DEA framework can be found. Such generalized approaches enable one to model the uncertainty inherent to the form of the production possibility set and the value of the technical efficiency measure at any given point of the former. In the paper we provide a detailed discussion of some statistical model and the subsampling algorithm which are used in statistical inference. The methodology is then illustrated with an empirical example using the real-world data from the Polish energy sector.

Opis:: Artificial Insemination (AI) in poultry production is a veritable technique in solving the problem of breeding and meeting the increasing demand. This study assesses the economics of artificial insemination in broiler production among sixty randomly selected broiler farmers in Nigeria. The analytical techniques employed include descriptive statistics, gross margin analysis, and stochastic frontier. The result discovered that most of the farmers are male and are at their prime age. Majority of the livestock farmers have some form of formal education and a minimum of 5 (five) year experience in poultry farming. The capital was mostly sourced from the bank. Majority of the farmers has a stock size of more than 25,000 birds. They have a gross margin of N341, 933,406. Only 20% of gross income was used for operating expenses with a return on capital invested of 4.3. The mean technical efficiency was 80.70%. Feed, vaccine and stock size were statistically significant in determining efficiency while education and extension visits are the statistically significant variable influencing technical inefficiency. It is therefore recommended that affordable and accessible input, as well as training should be made available to farmers to achieve self-sufficiency and improve the economy.

Opis:: This paper presents the results of an assessment of technical efficiency of innovations in European Union. Data Envelopment Analysis was used to investigate this subject. Results of simulation experiments were used to anticipate possible suggestions regarding policy measures that may be considered when exploring means to improve the Polish performance. Polish technical efficiency of innovations is below that in the European Union. Poland operates decreasing returns to scale. Special attention should be directed to education, research, and support to SMEs. It is essential to undertake legal changes relative to innovation activities and the attitudes of Poles towards innovativeness in order to improve results. In general the national Innovation System needs to be corrected [or improved]. The key aspect of improvement rests with congestion: overinvestment or inappropriate use of resources. Suggestions for further research of the subject and improvement of the National Innovation System are presented.
W opracowaniu tym przedstawiono wnioski z oceny technicznej sprawności innowacji w krajach Europy. W analizie wykorzystano metodę Data Envelopment Analysis, wspierając ją symulacją dla wskazania zakresów działań proinnowacyjnych, które charakteryzują się niską sprawnością realizacji. Techniczna sprawność innowacji w Polsce jest niższa niż innych krajów w analizowanym zbiorze. Polska działa w obszarze zmniejszających się zwrotów z tytułu skali. Szczególną uwagę poświęcić należy edukacji, badaniom i wspieraniu MŚP. Należy podjąć działania w kierunku zmiany obecnego systemu prawnego i nastawienia Polaków do innowacji, jeżeli oczekuje się poprawy sprawności działań proinnowacyjnych w przyszłości. Aby poprawić techniczną sprawność innowacji w Polsce, należy również usprawnić Narodowy System Innowacyjności. Podstawowym czynnikiem obniżającym techniczną sprawność innowacji w Polsce jest przeinwestowanie (i/lub marnotrawstwo nakładów na innowacje). W podsumowaniu podano sugestie kierunków dalszych prac badawczych nad poprawą funkcjonowania Narodowego Systemu Innowacyjności.

Opis:: The growth and development of the agricultural sector in developing countries is largely dependent on technological enhancements, because merely expanding the area of farm cultivation is no longer sufficient to meet the increasing food needs of growing populations. This study examined the effects of risk attitudes on the technical efficiency of small-holder rice farmers in Ogun State, Nigeria. Primary data were collected for the study using a multi-stage sampling technique, and 180 rice farmers were selected from the study area. The data were analyzed with descriptive statistics, stochastic frontier analysis and a simple lottery-choice experiment. The findings revealed that 36.1% of the farmers were between the ages of 31 and 40. Farmers who were 41 years and over were seen to be more risk averse than their younger counterparts. In this age group, 76.66% of rice farmers were risk averse, while 23.34% were risk tolerant. The result of the maximum likelihood estimate (MLE) of the parameters of the stochastic frontier analysis revealed that farm size positively and significantly influenced rice output (β = 0.16, p < 0.1), as did quantity of seed (β = 0.74, p < 0.01) and use of chemicals (β = 0.26, p < 0.01). Years of farming had a negative effect on technical efficiency (β = 0.64, p < 0.01), as did severe risk aversion (β = 0.57, p < 0.1). The study concludes that small-holder farmers are generally risk averse, negatively influencing technical efficiency in the study area. The study recommends that the design of government programs should incorporate farmers’ risk attitudes as an important variable.

Opis:: Aim: This study aims to evaluate the technical efficiency of 44 Brazilian port terminals that handled containers in 2016. The evaluation will first proceed by identifying the main benchmarks. It will then provide an analysis of variables that may have an effect on technical efficiency as well as the nature of their relationship with the latter--namely: container movement and specialized terminals. Design / Research methods: In this work we apply the techniques of Data Envelopment Analysis and Free Disposal Hull. Output-oriented models were constructed, using three inputs - berth depth, berth length and number of berths, and three outputs - number of containers handled, medium board measured in container handled per hour of mooring, and medium consignment rate measured in container throughput per ship. Conclusions / findings: The main results show that half of the terminals have an inefficient infrastructure, with capacity larger than necessary to meet current demand for transportation of containers. In addition, there is a strong relationship between the efficiency and size of a terminal port and between the efficiency and degree of specialization. Moreover, the private use terminal of (TUP) Itacal and public quay OCRIM can serve as benchmarks for most of the terminals. Originality / value of the article: Relatively few works in the literature tried to measure technical efficiency for developing countries. Besides that, none of the works found regarding Brazilian ports have shown the scenario after promulgation of the Port’s Law in 2013, and only a few used container cargo as focus. This article is of interest for scientists of the sector, exporters/importers, and Brazilian Government officers interested in observing the effects of public policies aimed at the sector. We also suggest future work concerning the sector's improvements which can follow from our findings.

Opis:: This paper analysed the economic efficiency of small-scale tomato farmers in the Greater Letaba municipality of South Africa’s Limpopo Province. Primary data were collected from 68 tomato farmers based on structured questionnaires and using convenience and purposive sampling procedures. The Cobb-Douglas production function was used to analyse the level of economic efficiency. The study utilised the output approach, where the output achieved by the farmers is compared to the maximum output attainable using the given inputs. The empirical results reveal that mean technical, allocative, and economic efficiency levels are at 0.95, 0.41 and 0.39, respectively. The study also found that land (farm size), seedlings, labour, pesticides and water have a positively significant relationship with the production of tomatoes in the study area. Therefore, it is recommended that the Department of Agriculture, Land Reform and Rural Development provide farmers with enough extension services by employing more extension personnel. Government programmes such as the Comprehensive Agricultural Support Programme should be intensified – through the pillar of training and capacity building – to reach the small-scale farmers in the municipality, whereby farmers should be provided with training on the recommended minimum and maximum application of inputs like pesticides, fertilisers, seedlings and water in tomato production.

Opis:: This paper assessed the trend of productivity of the existing six Nigerian ports. Secondary data was extracted from National Bureau of Statistics (NBS) Annual Reports, Nigeria Port Authority (NPA) Annual Reports, and Central Bank of Nigeria (CBN) Annual reports. Using the Data Envelopment Analysis technique, it was discovered that Calabar Port had been under-utilized towards the achievement of the required results. On the contrary, Rivers Port requires technical touches in her operations. As a liquid bulk port, the time of loading and discharging of commodities are often more than any other type of port and the turnaround time at this port are often more. Scale optimization is also required in Rivers Port. Inferentially, Lagos Port has been operating on optimal scale size but fluctuating managerial efficiency was experienced in the operation years. As a matter of findings, Tin Can Island has a similar trend to that of Onne Port with low productivities in the pre-concession period which improved consistently in the post-concession year of 2010 till the year 2015. It was also observed that Tin Can Island Port operated on under-utilization of inputs resources in the pre-concession periods till the post-concession year 2010. This reflects the element of wastefulness concerning both inputs and outputs quantities. Delta Port experienced fluctuating scale and technical efficiency trends in both pre and post concession years. Hence, it is observed that productivities' trends vary among the concessioned Nigerian Ports. These could be as a result of the influence of varied exogenous and endogenous factors on individual Port.
