본 연구에서는 우리나라에서 시행되었던 BTO 민간투자사업의 자료를 이용해 BTO 민간투자사업에 투자되는 민간자본에 대한 적정수익률을 추정하고자 한다. 과거 우리나라에서 진행되었던 민간투자사업의 경우 민간자본에 제공된 실질수익률은 대략 $6%\sim9%$ 수준이었는데, 본 연구의 결과에 따르면 정부가 최소운영수입을 보장해준 과거 민간투자사업의 경우, 민간자본에게 제공되었던 수익률은 적정 수준을 상당히 초과하는 것으로 나타났다. 특히 대부분의 민간투자사업에 있어 실제 운영 수입이 실시협약 당시 예측된 운영수입에 현저히 못 미친다는 점을 고려할 때, 민간자본에 대한 적정수익률은 더 낮아지게 되며 따라서 과거에 제공된 수익률의 적정수익률 대비 초과분은 더욱 커지게 된다. 본 연구결과는 향후 BTO방식 민간투자 사업을 진행할 때 정부와 민간사업자간의 실시협약조건에 민간 사업자가 부담하는 위험 대비 적정수익률이 반영될 수 있도록 하는데 도움을 줄 것으로 예상된다.

본고는 인공지능 산업의 발전이 우리나라 경제성장에 미치는 효과를 추정하여 최근의 4차 산업혁명 관련 기술혁신에 대한 경제적 시사점과 함께 관련 경제정책에 대한 함의를 얻고자 하였다. 인공지능 산업 발전 정도에 대한 대용변수로는 2018년~2020년 기간 소프트웨어 정책연구소가 조사한 '인공지능산업실태조사' 중 산업별 AI 관련업체의 매출액 및 특허출원 건수를 사용하였으며 경제성장 변수로는 산업별 총요소생산성과 산업별 GDP를 사용하였다. 추정 결과 AI 산업의 발전은 1년 정도의 시차를 두고 성장에 긍정적 영향을 끼치는 것으로 평가되었다. 특히 매출액 변수를 사용하였을 때 대정부 AI 매출이 GDP 성장에 미치는 효과가 민간 기업이나 소비자 대상 AI 매출에 비해 더 큰 큰 것으로 나타나 AI 산업 확산을 위한 정부의 정책적 노력이 다소 유의한 성과를 가져온 것으로 평가되었다. 다만 인공지능산업실태조사 자료의 기간이 다소 짧고 제조업에 대해서는 중분류 자료가 부재하다는 한계가 있어 관련 자료의 개선과 자료 축적이 진행될 경우 보다 강건한 결과를 도출할 것으로 기대된다.

The study assesses the impact of trade liberalization factors on changes in customs revenues in Vietnam. Research data was conducted between 2002 and 2017 on the official website of the Government's Web Portal and The World Bank. This paper uses the vector error correction model to estimate the short-term and long term relationship between data series. The results have proven that tariff reductions have a positive effect on short-term and long-term customs revenues in Vietnam. However, the implementation of other international commitments on trade liberalization has positive short-term and long-term negative impacts on customs revenues in Vietnam. The study's results also show that exchange rate has no effect on changes in customs revenues in the short term but it has a strong impact on increasing customs revenues in the long run. Based on these findings, the article also suggests a number of policies to ensure customs revenues in Vietnam in future. In order to ensure customs revenues, the government of Vietnam should: (1) having some policy to improve the efficiency of customs management in Vietnam; (2) Building appropriate VND exchange rate policy; (3) Establishing reasonable non - tariff barriers to prevent fraud and ovations cause losses in customs revenues.

소매업에 있어서 입지선정은 점포의 성패와 매우 밀접한 관계가 있는 핵심요인이기 때문에 출점 시 가장 중요하게 다루어져야 한다. 그러나 현재 대부분의 소매유통업계는 이러한 핵심적인 사항을 고려하지 않고 점포개발자들이 입지를 선정하기 위해 사용되는 상권분석 기법의 대부분은 단순통계자료와 느낌에 의존하고 있는 것이 사실이다. 점포 입지선정에 실패하는 주요 이유는 사업현장에서 종합적이고 체계적인 상권분석을 통한 점포출점이 이루어지지 못한데 있으며, 특히 슈퍼마켓 업계가 다른 소매업에 비해서 활용빈도가 현저히 낮은 편이다. 본 연구는 중대형 슈퍼마켓을 운영하는 업체가 점포 입지를 선택하기 위한 상권분석 시 활용할 수 있는 모형의 구축을 위하여 광역상권을 모델로 한 기존의 상권분석 모형을 이용하여 중소상권의 상권분석에 적용시켜 연구를 진행하고, 상권분석 연구의 결과를 이론으로 정립하고 정립된 이론을 근거로 모델 점포의 예상매출을 추정하여 실제매출과 비교검증 하였다. 쇼핑확률 산출과정을 통해 얻어진 결과로 기존의 수정허프모델를 이용한 개량확률모델의 새로운 모형구축을 위해 컨버스의 신소매인력모델을 이용하였다. 그러나 쇼핑확률을 산출하기 위해서 수정허프모델을 이용하되 기존의 방법에 반영되는 변수들을 다르게 반영함으로서 광역상권 분석기법으로 중소상권을 분석할 경우 우려되는 차이를 최소화하여 소비자가 점포를 선택하는 조건을 쇼핑확률 계산에 가중치를 반영, 객관성과 신뢰성을 높이는 연구를 실시하였다.

Purpose - This paper empirically investigates the effect of a rise in the global value chain (GVC) on the industry-level efficiency of resource allocation (based on plant-level inefficiency measures) in Korea, with a focus on various channels through which a rise in the GVC can increase competition among firms and thus induce resources to be allocated more efficiently across firms. Design/methodology - We empirically investigate the relationship between the industry-specific importance of GVC and the industry-level allocative inefficiency that is measured as the dispersion of the plant-level marginal revenue of capital (MRK) as in Hsieh and Klenow's (2009) influential model. We compute MRK dispersion for industries sorted by various characteristics that are closely related to firm/industry sensitivity to the GVC. In other words, we compute the average industry-level MRK dispersion for industries sorted by industry-specific importance of GVC and compute the difference between the two groups of industries (higher vs. lower than the median GVC); we also calculate the difference between industries sorted by industry-specific export (import) intensity. This is our difference-in-difference estimate of the MRK dispersion associated with the GVC for the export (import)-intensive industry versus the non-export (non-import)-intensive industry. This difference-in-difference estimate of the MRK dispersion conditional vs. unconditional on firm-level productivity is then calculated further (triple-difference estimate). Findings - A rise in GVC is associated with a decrease in the MRK dispersion in the export-intensive industry compared to the non-export-intensive industry. The same is true for industries that rely heavily on imports versus those that do not (i.e., import intensive vs. non-intensive). Furthermore, the reduction in the MRK dispersion in the export-intensive industry associated with an increase in the GVC is disproportionately greater for high-productivity firms. In contrast, the negative relationship between GVC and MRK dispersion in the import-intensive industry is disproportionately smaller for high-productivity firms. Originality/value - Existing studies focus on the relationship between GVC and aggregate output, exports, and imports at the country level. We investigate detailed firm/industry-level mechanisms that determine the relationship between GVC, trade, and productivity. Using the plant-level data in South Korea, we investigate how GVC is related to the cross-firm MRK dispersion, an important measure of allocative inefficiency, based on Hsieh and Klenow's (2009) influential economic theory. This is the first study to provide plant-level evidence of how GVC affects MRK dispersion. Furthermore, we examine how the relationship between GVC and MRK-dispersion varies across export intensity, import intensity, and firm-level productivity, providing insight into how GVC can affect firms' exposure to competition in the global market differently depending on market conditions and thus generate trade-related productivity gains.

Purpose: This paper analyzed alternative methods of calculating the conversion factor for nurse-midwife's delivery services in the national health insurance and estimated the optimal reimbursement level for the services. Methods: A cost accounting model and Sustainable Growth Rate (SGR) model were developed to estimate the conversion factor of Resource-Based Relative Value Scale (RBRVS) for nurse-midwife's services, depending on the scope of revenue considered in financial analysis. The data and sources from the government and the financial statements from nurse-midwife clinics were used in analysis. Results: The cost accounting model and SGR model showed a 17.6-37.9% increase and 19.0-23.6% increase, respectively, in nurse-midwife fee for delivery services in the national health insurance. The SGR model measured an overall trend of medical expenditures rather than an individual financial status of nurse-midwife clinics, and the cost analysis properly estimated the level of reimbursement for nurse-midwife's services. Conclusion: Normal vaginal delivery in nurse-midwife clinics is considered cost-effective in terms of insurance financing. Upon a declining share of health expenditures on midwife clinics, designing a reimbursement strategy for midwife's services could be an opportunity as well as a challenge when it comes to efficient resource allocation.

This article suggests a methodology to decide the priority of investment project for venture business under the dynamic circumstance. By the Monte Carlo procedure on the probability distribution of cost and revenue, the model simulates the investment project to estimate profit ratio and risk. The profit ratio is calculated on the yearly basis for the relative comparison. The project risk is calculated as semi-variance under the target yield. After sufficient simulations in this fashion for several projects, the efficient projects with more profit and less risk are selected by the dominance principle. Then the regression equation of the selected projects is produced to find the relative value of the projects. The relative value is obtained through dividing the raw profit ratio by the estimated one on the equation. This value shows the degree to which the simulated project yields over the equation. The priority of investment is decided by this value. An examplary venture business of chemical development for semi-conductor is presented as a case study.

This study is conducted to estimate economic ripple effects of subsidiary services of hospitals. Using the Input/Output Analysis, this study analyzes production inducement effect, added value inducement effect, and labor inducement effect. Also, it assesses potential economic effects of the subsidiary services of which the scope is expanded as the government's proposed in 2014. Data regarding hospital subsidiary services and economic effects are obtained from the hospitals' financial statements on the National Tax Services and the Bank of Korea. The major results of this study are summarized as follows; subsidiary service profits of hospitals are 466 billion won and rent profits of hospitals are 152 billion won. Of these, the rate of subsidiary service profits in tertiary hospitals is about 66% of total subsidiary service profits. Producement inducement effect of subsidiary services of hospitals is higher than that of total industry, service industry and medical service industry. Added value inducement effect of subsidiary services of hospitals is higher than that of total industry, manufacturing industry, service industry and medical service industry. Job position inducement effect of subsidiary service in hospitals is higher than that of total industry, service industry and medical service industry. Also, employment inducement effect of subsidiary service in hospitals is higher than that of total industry and medical service industry. The results may suggest that subsidiary services revenue in medical institutions contribute to improving operating profits. Facing with intense market competition and pressures to control health care costs, hospitals may need to determine whether subsidiary services help boost their profitability and improve customer satisfaction.

Purpose: The purpose of this study was to perform an economic analysis and estimate the fee for the practices that carried out by Emergency Nurse Practitioner (ENP) using relative value scale (RVS) and its conversion factor. Methods: First, we developed ENP's RVS for 25 advanced nursing services based on ENP's workload and its time spent by survey. A cost analysis was performed to evaluate the conversion factor of ENP's RVS. The share of ENP's contribution to fee-for-service in emergency setting was also analyzed. Results: Calculation of the RVS of 25 advanced nursing practices showed a range of points from 73.4 to 296.3 and an average of 145.1 points. The relevant conversion factor for advanced nursing practices among ENP was estimated at 12.2~15.9 won. The contribution rate of ENP's advanced nursing practices in the relative value scale of the national health insurance was estimated at 13.1~17.0%. Conclusion: The practices of ENP are not compensated separately and its reimbursement is usually included in physician fee. An estimation of nursing fee and an independent fee related to ENP's services shows the contribution rate to total revenue. It suggests that emergency nurse practitioners be considered as a revenue source the in emergency room.
