The purpose of this study is to evaluate the managerial efficiency of fisheries cooperatives in Korea by using data envelopment Analysis(DEA). The DEA method is a relative evaluation method on the basis of linear programming. Also, it is known as a useful method for the evaluation of not-for-profit organizations which cannnot be measured by mere monetray units for their performances. The 50 units have been taken for the purpose of analysis. All of the units are homogeneous groups, and the produce multiple services with multiple inputs. Input variables are a number of employee, fixed assets, and business managerial costs. Output variables include a number of deposits, a number of loans, a total deposits, a total loans, and operational income for one year. The empirical results of this study are as follows. First, the average technical efficiency showed 82.35% which revealed about 17.65% of non-efficiency in 2001. Second, in 15 DMUs, the overall inefficiency is mainly attributed to their efficient operations or management. To be opposed, in 18 DMUs, the overall inefficiency is mainly attributed to their scale efficiency. Third, efficiency ranking results by DEA do not agree with the ratio analysis by fisheries cooperatives. Fourth, average efficiency level by year was improving gradually by 0.7408 in 1999, 0.8023 in 2000, and 0.8235 in 2001 at significant 10% level.

This study is designed to measure the relative efficiency of regional fishery cooperatives based on Data Envelopment Analysis(DEA) methods. Selecting 40 regional fishery cooperatives in Busan as Decision Making Units (DMUs), the study uses their panel data from 2007 to 2008 to rank the relative efficiency of the DMUs. First, the efficiency score of the DMUs are calculated using CCR, SBM, and super-SMB model. Within the model, input variables are the number of employees and area of fishery cooperatives. Output variables are the amount of deposit money, loan and profit. Based on the efficiency scores calculated from super-SMB model, the efficiency ranking of the DMUs is determined. Second, the differences in average efficiency calculated from the three DEA models are tested using a pair-wise mean comparison test. The results based on the efficiency scores evaluated from super-SMB model show that seven out of the forty DMUs are efficient; among the efficient DMUs, the DMUs that can be benchmarked for inefficient DMUs through the frequency analysis of reference set being identified. Third, the differences in average efficiency of the three DEA models between 2007 and 2008 are tested using pair-wise mean comparison test and the study estimates the efficiency change of the DMUs between 2007 and 2008 using Malmquist productivity index(MPI). Finally, the paper suggests an improved composite DMU superior to the inefficient DMUs evaluated by Super-SBM model.

This paper aims to determine whether the changes in management performance of domestic agricultural cooperatives had an effect on the election results of Korean Agricultural Cooperatives in 2015. Financial performance data (2012-2015) prior to the Nation-wide Cooperatives elections in 2015 were reviewed to determine the impact of the election outcome on the election results. 2SLS Probit regression analysis shows that the significant parameters for incumbent president turnover in the 2015 election were the candidates' age, net profit decrease in 2014, and ROA comparison to similar asset-size group. These results support the conclusion that the union members of KAC consider whether the age of president is over 60, whether the net profits of the cooperatives are worse than the previous year, and compare the results of similar groups' managerial performance (ROA).

This study examines performances of cooperatives relative to investor-owned firms in the US electric power industry. Using a panel data of firms from 2001 to 2014, the results show that cooperatives operate under conditions of more difficult capital constraints associated with the higher cost of debt and limited access to external equity capital. While investor-owned utilities, especially the large utilities that are less capital constrained, take benefits from substantial scale economies existing in the industry, the marginal cost of operation substantially increases with output for cooperatives. I do not find differences in profitability between the two ownership structures, measured by return on assets and return on equity. Plant capacity utilization, which is a measure of plant efficiency conditional on the operation, is also not statistically different between the two groups.

Since domestic and international environments has changed rapidly, Korean primary agricultural coopratives are expected to face many difficulties in business management, especially marketing and banking business. Therefore, it is necessary to reframe the exitsting structure of primary agricultural cooperatives so as to enhance the competitiveness in terms of management efficiency. However, There are many problems to be solved such as overnumbered staffs compared with decreasing number of farming population, unbalanced ratio between executive officials and lower-level officials, complexity of position-ranking system resulting from unclearness of official title and office regulations, and management right excessively concentrated on cooperative leader. The suggested measures for such problems are as follows; 1) attaining the economy size of agricultural cooperaitves in line with decreasing rural community, 2) fostering the on-the job training programs and the personnel administration according to job competency, 3) merging the small primary cooperatives into larger units with efficiency, 4) specializing the cooperative business based on their regional comparative advantage, 5) maintaining the rational adjustment between elected cooperative leader's management right and responsibility.

Accessibility to medical facilities and personnels has been known as one of important determinants of medical care utilization. This study attempted to identify the effects of medical accessibility in terms of geographical distance and occupational opportunity to the medical utilizations. Two-year-experiences of Yonsei University Health Insurance Cooperatives were used as the sources of data. Out patient utilization patterns of 713 members sampled from 4,352 members of Health Insurance Cooperatives were analyzed in order to identify the effects of medical accessibilities. Findings: 1 Average clinic visit rate of Yonsei Health Insurance is 1.66 per person per year. 2. The utilization rates of geographically more accessible group were 33% higher than that of less accessible group. 3. No marked difference in clinic visit rate were observed between medical and non-medical personnel and their family members. 4. Clinic visit rates among occupationally accessible group were slightly higher than those of less accessible. The utilization rate was more sensitively changed by the insurance policy changes in occupationally accessible group.
