Important Solution

For a common small- to medium-sized fish farm in an agricultural-based economy, monitoring costs is very important, since financial constraints are always a problem for these farmers. This will be thus easier if the farmers can get access to external funds. This paper used data envelopment analysis (DEA) to examine the technical efficiency, cost efficiency and allocative efficiency of 639 fish farms in the Red River Delta (RRD) in Vietnam in 2018 to see how fish farmers control their costs and if financial access can really help in this matter. We found that these fish farms were very inefficient, meaning that they did not succeed in monitoring and allocating their costs and resources. Among the factors that could improve their efficiency, we found that developing the rural banking system to provide more financial access for RRD fish farms is an important solution.

European Banks

This study examines whether and how the stress testing of European banks in 2010, 2011, and 2014 is related to their technical, allocative, and cost efficiency. Using a sample of large commercial banks operating in 20 European countries, and Data Envelopment Analysis (DEA), the authors perform comparisons between banks that were included in one of the three European stress tests and untested banks operating in the same countries. They estimate various specifications as for the inputs and outputs, cross-section and pooled estimations, and they also examine alternative samples as for the ownership of banks. In general, the authors conclude that banks included in the stress-test exercises are more efficient that their counterparties. The differences tend to be statistically significant in the case of allocative efficiency and cost efficiency, but not in the case of technical efficiency. With regards to the latter form of efficiency, the results depend upon the specification and the stress test in question.

Constant Returns To Scale

The lending environment in the Indian commercial banking industry changed considerably in the reform years following widening of priority sector definition, dismantling of Credit Authorisation Scheme and introduction of risk based supervision. In this context, the present paper attempts to compare the performances of commercial banks in the reform period in respect of lending (in a cost minimisation framework) making use of Data Envelopment Analysis – a non-parametric method which is quite suitable for making inter-(productive)unit comparison. The commercial banks have been assumed to obey constant returns to scale. The results obtained from the study are as under: (i) The observed private sector commercial banks exhibited higher mean cost efficiency than the observed public sector commercial banks. This is perhaps indicative of the problems that persist in the lending environment which caused the public sector commercial banks to shy away from lending. (ii) The difference in cost efficiency scores emanated mainly from differences in mean allocative efficiency scores exhibited by the two bank groups. Further, the observed commercial banks show considerable fluctuations in allocative efficiency scores across the years.

Decision Making Units

Data Envelopment Analysis (DEA) is an appropriate tool for estimating various types of efficiency such as cost efficiency. There are two different sates in cost spaces; in the first space prices are equal for all Decision Making Units (DMUs) which is competitive space, and in the second space prices are different form one DMU to another; this is known as non-competitive space. The present paper introduces a new method to assess Cost Efficiency (CE), Revenue Efficiency (RE) and Profit Efficiency (PE) in a non-competitive space. The present paper also proposes a Production Possibility Set (PPS) in which DMUs are evaluated based on both their own prices and the prices of other DMUs in non-competitive space. Moreover, a new decomposition is provided for observed actual cost DMUs based on the cost efficiency model and the proposed PPS, thus the observed actual cost can be shown by summation of several technical, price and allocative efficiency (AE) losses. The biggest advantage of this method comparing to the previous methods is that passive the developed cost efficiency and the cost Production Possibility Set has been developed and the performed decomposition is more accurate; this is because the new inefficiency sources are defined and added to this new decomposition. Therefore, it includes more inefficient sources.

AbstractThis study estimates the cost (technical) efficiency of the banking system in Occupied Palestinian Territory (OPT), using a panel of 18 banks during the period 2000–2009. Estimates have been obtained using the stochastic frontier approach. The analyses were extended to cover bank ownership (foreign and local), type (Islamic and commercial) and bank size. Results indicate that the overall cost (technical) efficiency of banks in the OPT is declining during the period of research. The mean of cost and technical efficiency was found to deteriorate through the years. Cost efficiency declined from 0.730 in 2000 to 0.666 in 2009, while technical efficiency declined from 0.733 to 0.713 during the same period. Moreover, the lower allocative efficiency (incorrect input mix rather than utilization or wasting resources) is the main cause of the decline in cost efficiency over the period of analysis. In addition, large banks have lower cost efficiency, which indicates the presence of diseconomies of scale for banks in OPT.

The concept of cost efficiency has become tremendously popular in data envelopment analysis (DEA) as it serves to assess a decision-making unit (DMU) in terms of producing minimum-cost outputs. A large variety of precise and imprecise models have been put forward to measure cost efficiency for the DMUs which have a role in constructing the production possibility set; yet, there’s not an extensive literature on the cost efficiency (CE) measurement for sample DMUs (SDMUs). In an effort to remedy the shortcomings of current models, herein is introduced a generalized cost efficiency model that is capable of operating in a fuzzy environment-involving different types of fuzzy numbers-while preserving the Farrell’s decomposition of cost efficiency. Moreover, to the best of our knowledge, the present paper is the first to measure cost efficiency by using vectors. Ultimately, a useful example is provided to confirm the applicability of the proposed methods.

Climate change (CC) and its impacts on the socio-economy and the development of communities has become an issue causing very special concern. The rise in global temperatures, in sea levels, extreme weather phenomena, and salinization have occurred more and more and have directly influenced the livelihoods of rural households in the Red River Delta – one of the two regions projected to suffer strongly from climate change in Vietnam. For farming households in this region, the major and traditional livelihoods are based on main production materials as agricultural land, or aquacultural water surface Changes in the land use of rural households in the Red River Delta during recent times was influenced strongly by the Renovation policy in agriculture as well as the process of industrialization and modernization in the country. Climate change over the past 5 years (2005-2011) has started influencing household land use with the concrete manifestations being the reduction of the area cultivated and the changing of the purpose of land use.

Overall the evolution process of the Red River Delta based on the maps and historical data resulted in a fact that before the 20th century all the Nam Dinh coastline was attributed to accumulation. Then started the erosion process at Xuan Thuydistrict and from the period of 1935 - 1965 the most severe erosion was contributed in the stretch from Ha Lan to Hai Trieu, 1965 - 1990 in Hai Chinh - Hai Hoa, 1990 - 2005 in the middle part of Hai Chinh - Hai Thinh (Hai Hau district). The adjoining stretches were suffered from not severe erosion. At the same time, the Ba Lat mouth is advanced to the sea and to the North and South direction by the time with a very high rate.The first task of the mathematical modeling of coastal line evolution of Hai Hau is to evaluate this important historical marked periods e. g. to model the coastal line at the periods before 1900, 1935 - 1965; 1965 - 1990; 1990 - 2005. The tasks is very complicated and time and working labors consuming.In the paper, the primarily results of the above mentioned simulations (as waves, currents, sediments transports and bottom - coastal lines evolution) has been shown. Based on the obtained results, there is a strong correlation between the protrusion magnitude and the southward moving of the erosion areas.
