Opis:
Aim: In this paper we are looking at the seaports (in India called ‘major ports’) from the context of its trade and India’s strategic importance in trade world after the initiation of economic reforms in 1991. It empirically estimates the levels of productivity and efficiency of seaports in India. This paper applies DEA technique to assess productivity and efficiency of seaports in India.   Design/Research methods: DEA technique is extensively used in the literature of economics to provide measures of firms’ technical efficiency. These measures rank the firms by looking at their apparent performances over a period of time. DEA is a frontier model which is non-parametric since no functional specification or form is required to be mentioned.   Conclusions/Findings: The DEA results as discussed and reported in the paper have shown how Indian ports are performing over the years. This investigation alone is not sufficient to develop a benchmark in the port system of India. Rather it will do well to have a closer look at the Indian ports from the physical and financial performance point of view. This study made use of data envelopment analysis (DEA) to generate what we call an efficiency benchmarks and assessment of the Indian ports sector. With this modest attempt to investigate the port sector of India several issues are in the open one can further analyze and come to desired conclusions.   Originality/value of the paper: The main role of a port is to transfer goods between two transport modes. As far as Indian ports are concerned, there are few studies with regard to productivity and efficiency of the port sector. Since, there is an attempt in recent years to overhaul the infrastructure sectors of the Indian economy and especially seaports. There is a need to look at issues in port sector as well. Productivity and efficiency concerns should be the main aspect of the benchmarking of the performance of today’s Indian ports.   Limitations of the research: Second stage DEA, distance function approach, Bayesian techniques, Carlo Monte techniques, can be alternatively used.

Opis:
The primary objective of the article was to examine the level and efficiency structure of insurance companies on life insurance market  in Poland. The study presents critical analysis of the insurance literature relating to technical efficiency of insurers, i.e. methods of estimating efficiency, the form of the efficiency  frontier  model, the choice of production factors and insurance production. The study used the methods of mathematical and econometric modelling in SFA  method. The results the technical efficiency study for 22 life insurance companies for a period between 2011-2020 using the SFA method, showed high average cost efficiency of insurers (0.9140) and lower profit efficiency (0. 8565). It was confirmed that a group of large companies achieved higher cost efficiency than the remaining companies, suggesting that large companies benefited from the scale of production.  In contrast, higher average profit efficiency was recorded for the remaining companies.

Opis:
Aim: The main objective of this research was to evaluate the efficiency of economic costs in seven units of greenhouse tomato production, during the production cycles of 2016, through the application of the stochastic frontier, depending on the type of packaging they handle and the cost structure that governs them.   Design / Research methods: The stochastic frontier model includes the analysis of the non-systematic random component, which assumes an extremely critical role in the analysis during the interpretations. With the calculation of the stochastic cost frontier we construct the cost inefficiency index represented by C_it, delimited below 0. The index shows the percentage in which the cost is exceeded and, therefore, the degree of inefficiency.   Conclusions / findings: The elaboration of the stochastic frontier finds its justification in the argument that the less efficient competitor is the one that receives the greater effects of the competition. In this sense, the location of the companies analyzed with respect to their own line of efficiency is essential for the design of the strategies of each company. The production units analyzed showed that, on some occasions, externalities are the cause of inefficiency, but contrary to what is established in theory, there are some units that show that the inefficiency with which they count is diminished by The influence of uncontrolled variables.  Originality / value of the article: The contribution of this research lies in the use of efficiency models in the primary sector, specifically in tomato´s greenhouses.

Opis:
In real applications of data envelopment analysis (DEA), there are cases in which undesirable outputs are produced along with desirable outputs in such a way that the total sum of the produced undesirable outputs over the production units must be fixed and constant. In this case, a trade-off between the decision-making units (DMUs) is needed to balance the production of undesirable outputs. In a rational sight, this trade-off is done in such a way that all DMUs improve their relative performances. In this paper, a single DEA-based model is proposed to model fixed and variable-sum undesirable outputs in production processes. A common equilibrium efficient frontier is constructed and after reallocating the input/output factors, all decision-making units (DMUs) prevail as efficient. A real case of 32 paper mills in China is given. The results of the analysis demonstrated that some economically developed paper mills have better performance than less developed paper mills; in particular, all efficient paper mills are the developed ones.

Opis:
The role of information in agricultural development cannot be overemphasized, as information is vital in increasing production, improving marketing and enhancing distribution strategies. Therefore, the study examined the impact of information communication technologies on the technical efficiency of fish farming in Ogun State, Nigeria using a stochastic production frontier approach. In a cross-sectional survey, a multi-stage sampling technique was employed to elicit primary information from 120 fish farmers. Major ICT sources used by the fish farmers include television (81.7%), radio (79.2%) and the Internet (68.3%). The average output of catfish has positive and significant elasticity with regards to each input variable except family labour. The inefficiency model revealed that the age of farmers, farming experience, television and radio usage were significant but negatively related. That means that any increase in any of these factors will reduce the inefficiency of fish farmers and bring about an increase in technical efficiency. This implies that it is possible to increase technical efficiency in fish farming in the study area provided that the media channel (radio and television) predominantly used is improved. This study recommends a reduction in family labour usage while at the same time encouraging young people to venture into fish farming.

Opis:
Maize production is the most important field crop in South Africa produced from ancient years, Mpumalanga and North West Provinces being principal producers. Maize is extensively produced and ascendancy ground crop because maize is greater resilient, less labor exhaustive, rich in food strength and starches, grows actual fast, and easy to produce as other ground crops. Most of the produced maize in South African is consumed domestically. Despite massive extents of arable land and all-inclusive land reform implemented for 25 years, farmers in the former homeland areas of South Africa cultivate only small food plots where they grow mostly maize and a small variety of vegetables. The aim of this paper was to examine the technical efficiency of maize-based farmers who farm within smallholder irrigation schemes. A multi-stage sampling procedure was used to select 120 maize-based irrigation farmers. Descriptive statistics and stochastic production frontier models were used in the study. Maize production in the study area was dominated by males (78%) with an average age of 60 years and an average family size of 4 people in the household.  Smallholder irrigators have primary education meaning farmers were literate and able to access farming information and interpret it. Farmers have a minimum average of 10 years of farming experience. Smallholder maize-based farmers were efficient in using their resources given their high farm productivity. The level of technical efficiency for maize farming was 84% which indicates that 16% of maize yield was not realized by smallholder maize farmers in the study area. The study recommends that the government and private sector must improve the farm techniques such as manure and enhanced seeds prepared early and accessible at small and affordable expenses to upsurge maize productivity.

Opis:
The paper investigates Bayesian approach to estimate generalized true random-effects models (GTRE). The analysis shows that under suitably defined priors for transient and persistent inefficiency terms the posterior characteristics of such models are well approximated using simple Gibbs sampling. No model re-parameterization is required. The proposed modification not only allows us to make more reasonable (less informative) assumptions as regards prior transient and persistent inefficiency distribution but also appears to be more reliable in handling especially noisy datasets. Empirical application furthers the research into stochastic frontier analysis using GTRE models by examining the relationship between inefficiency terms in GTRE, true random-effects, generalized stochastic frontier and a standard stochastic frontier model.

Opis:
Local government units in Poland are obliged to improve the quality of life of their inhabitants concerning rules of sustainable development. The study described in the article is intended to measure the relative efficiency of management including examination of the relationship between various inputs and outputs in local government units. The analysis in the paper shows efficiency differences between local governments in comparison with sub-region leaders (group frontiers) and region leaders (meta-frontiers). The division into sub-regions and regions was made according to NUTS classification. The measurement of inputs and outputs in local government management units was based on indicators of sustainable development from SAS (Local Government Research System) database. Apart from static comparison (for a particular year) the main purpose of the article is to show changes of efficiency in 5 years horizon with application of dynamic meta-frontier approach. The outcome of the analysis made it possible to indicate some reference points (benchmarks), which may contribute to improve the efficiency of management in the local government units in Poland under research. The concepts delivered in the paper are employed for the purpose of assessing growth performance of local governments using a data set covering 128 cities in period 2006-2010.
