One of the main challenges receiving much attention in the Rwandan agriculture and food industry in recent decades is the increases in maize prices. Indeed, a rise in maize prices causes higher living expenses for households because maize, which is a major staple food crop, constitutes a significant share of total food consumption among households in Rwanda. The aim of this study was to assess the extent of integration and how prices are transmitted between retail and wholesale markets of domestic maize in Rwanda. This study used monthly data of retail and wholesale prices of maize from January 1995 to December 2019. This empirical investigation was based on a linear cointegration approach and an asymmetric error correction model framework. Using the augmented dickey-fuller residual-based test and the Johansen Maximum Likelihood cointegration test, the results revealed that the retail and wholesale markets of maize are integrated. Hence, prices in these markets do not drift apart in the long run. The results of the Granger causality test revealed that there is a unidirectional causal relationship flowing from wholesale prices to retail prices, i.e., wholesale prices influence retail prices. Accordingly, the results from the asymmetric error correction model confirmed the presence of a positive asymmetric price transmission between wholesale and retail prices of maize in Rwanda. Thus, we suggest that policymakers take a critical look at the causes and factors that may influence asymmetry price transmission.

In the past, companies should make enormous facility investment and acquire a right to do business in order to join communication markets, but now they can do business without important facilities, such as communication networks. Such a movement to ease regulations about companies which want to newly join the communication industry is expected not only to change a competition frame of the mobile communication market but also to greatly affect the entire communication industry. Through this study aiming to look into a way to calculate a reasonable wholesale price related to the government's introduction of the Mobile Virtual Network Operator (MVNO) system, I came up with a following result. I applied the operating profit percentage and the ratio of operating gain to cost to the cost plus model and retail minus model, respectively, to calculate the wholesale price and found that when I calculated with the cost plus model applying the operating profit percentage, I could get the highest wholesale price. On the other hand, I got the lowest wholesale price with the retail minus model by applying the operating profit percentage. Division of expenses and calculation of profit percentage are important factors in calculating the wholesale price and such results are expected to help accurate calculation of the MVNO wholesale price.

The purpose of this survey was to identify ergonomic risk factors of work-related musculoskeletal disorders (MSD) and understand the current MSD risk status in the wholesale/retail industry. The field survey was conducted at 120 wholesale/retail establishments, and the cause of MSD occurred from the national industrial accident statistics by the Ministry of Labor in 2006 was analyzed in terms of company size, a term of work, job title, and cause of occurrence. The numbers of disasters on MSD were 602 which were included 432 disasters who met with low back pain by incident. A checklist was developed by KOSHA to use for the field survey. A total of 419 tasks were identified at the 120 establishments surveyed. The highest frequency was Task 2(45%) which was mostly observed in repetitive work (e.g. displaying, scanning, cutting or wrapping of goods). The second and third were Task 9(34%) and Task 8(14%) which were identified in manual materials handling (e.g. lifting, lowering, carrying or stocking of goods). The results suggest that the three Tasks should be first considered for the control in wholesale/retail industry and that exposure to MSD risk factors in those Tasks should be primarily addressed in order to reduce MSD risk in that industry.

Purpose: This study examines the relationship between formation of employment subcenters and regional industrial structures in Incheon. Research design, data, and methodology: We used the five-year panel data from 2012 to 2016 in 146 basic municipal units of Incheon to analyze panel regression models. Gross employment density and employment to population ratio were used as indicators of employment subcenters formation. The entropy index and Hachman index were used for analyzing the diversity and heterogeneity of industrial structures. Result: The analyses of two panel regression models showed that for the formation of employment subcenters, both the Entropy and Hachman index were significantly negative in most models. But tertiary industry was shown to have a significant positive relationship in all models. In the wholesale and retail sector, it was found that the average number of employees in the employment subcenters is significantly higher than that in the non-employment subcenters. Conclusions: The specialization of the industrial structure rather than the diversification contributes to the formation of the employment subcenters in Incheon. In particular, it can be considered that the wholesale and retail sector plays a very important role in forming the employment subcenters in many areas of Incheon.

본 연구에서는 벡터오차수정모형(VECM)을 이용하여 유통단계별 감귤시장의 가격전이 메커니즘을 이해하고 가격 결정력을 지니는 유통단계를 확인하고자 하였다. 일반적으로 농 축 수산물의 유통과정은 도매시장에서 소매시장으로 가는 2단계 유통과정을 거친다. 그러나 경우에 따라서는 산지 도매시장에서 소비지 도매시장을 거쳐 소비지 소매시장으로 가는 3단계 유통과정을 거치는 경우도 있다. 이렇게 각 시장에서 형성되는 농 축 수산물의 가격은 유통마진의 격차를 두고 서로 밀접한 연관을 지니며 움직이는 것이 특징이다. 그러나 각 시장의 가격결정 과정에서 농어업인, 도소매 유통인 및 가공업자 등의 시장지배력, 소비자 또는 정부의 영향력에 따라 각 시장의 가격생성 메커니즘이 영향을 받을 것이고, 이에 따라 각 시장의 인과행태가 발생할 것이다. 제주감귤 역시 생산자 단체와 산지 유통인을 통하여 도매시장이나 대량 수요처 등으로 운송되며 도 소매시장 및 대형유통업체를 통하여 최종 소비자에게 유통되고 있어 전반적으로 도매시장에서 소매시장으로 가는 2단계 유통과정을 거치고 있다고 볼 수 있다. 본 연구의 주요 결과는 다음과 같이 요약할 수 있다. 첫째, 감귤의 도매가격과 소매가격 간의 유통단계별 수준변수 시계열에서 장기균형관계가 성립하였다. 둘째, 감귤 가격의 도매시장과 소매시장 간의 인과방향은 단기적인 측면에서 도매시장에서 소매시장으로의 일방적인 인과방향을 확인할 수 있었다. 셋째, 장기적인 측면에서 감귤 가격의 도매시장과 소매시장 간에는 서로 쌍방향적인 피드백 효과가 있는 것으로 분석되었다. 이러한 결과는 감귤 유통시장에서 도매가격이 가격형성에 가장 중심적인 역할을 하며, 감귤의 가격결정에 있어 도매시장의 영향력이 매우 크게 나타나고 있음을 의미한다고 하겠다. 결국 경쟁력 있는 감귤산업의 발전을 위해서는 산지 조직화를 통한 감귤생산의 수급조절 정책의 적극적인 추진이 필요한 것으로 사료된다.

Purpose: At a time when the distribution industry is dominated by capital and technology, win-win growth among businesses groups (BGs) in wholesale market is becoming a social issue. Therefore, through analysis of market growth, market concentration (MC) and market power (MP), we want to identify the structure of the wholesale market and the competitiveness of the BGs in terms of market share (MS), sales-profit ratio (SPR), and labor productivity (LP) to explore the possibility of win-win growth. Market situation: Wholesale and Retail sales ratio (W/S) continues to increase, which also means inefficiency in distribution channels or opportunities in wholesale markets. Wholesale sales have grown 8.3 percent annually over the past 15 years, while the number of companies and workers has declined since 2017, which is why some restructuring is believed to begin in the wholesale industry. In terms of MC and MP, the growth potential of SBG can be found in FCB, ARM, FBT and CME BTs. Methodology and data: Through ANOVA and Regression Analysis, the 2015 Economic Census Data of KOSTAT was analyzed. Results: The results of ANOVA show that statistically significant SBG has a larger MS than LBG. The SPR was not different among BGs. LP is higher for LBG than for other BGs. Regression results show that the employment weight (EW) and the company size (SC) have positive effects on the MS, but the company weight (CW) and employment size (SE) have negative effects. In the case of SPR, the CW is positive and the EW is negative. In addition, LP appears to be more positive as SC in the BGs is larger. Conclusions: Although there is sufficient potential for SBG in the wholesale market, there is a problem that needs to increase LP. Therefore, the SBG needs to restructure in terms of number of companies and SC to improve the efficiency of employment. In terms of MC and MP, the SBG looks for possibilities in FCB, ARM, FBT and CME BTs. In addition, SBG that seeks higher returns with human services rather than simple sales is found to be competitive in the HHG, MES and CME BTs.

1968~1991년 사이에 도매업 판매활동에 의한 한국의 도시유형 변화를 분석한 결과 다음과 같은 점이 밝혀졌다. 1. 양년도 사이에 생산. 소비제 관계 도매업 특히 {농산물 및 음식료품} 도매업에 치우친 업종구성에서 기계 및 장비, 운수장비 등 투자재의 수요확대를 반영하는 도매업의 발달을 가져왔다. 2. 1970년대에는 중.소도시의 도매업 성장이, 1980년대에는 대도시의 도매업 성장이 이룩되었다. 그리고 6대 도시의 도매업 판매액의 집중률이 낮아졌으며, 특히 서울.부산의 집중율이 낮아졌다. 3. 최근 소득의 향상과 더불어 구매력 증대를 배경으로 1970년대에는 자동차 부품, 타이어 도매상점수가, 1980년대에는 사무용 기기, 자동차 도매업의 상점수가 크게 증가한 것이 도시유형을 변화시킨 원인이다.
