부산시는 택시활성화를 목표로 신규 택시이용 수요를 창출하기 위해 2017년 10월부터 전국최초로'택시환승할인'을 실시하였다. 그러나 환승할인 금액이 적고 결재수단이 선불카드에 한정된 문제 등으로 이용실적이 적어 정책이 제대로 시행되고 있다 보기 어려운 상황이다. 이에 본 연구에서는 택시환승할인 이용실태, 택시환승할인요금 수준에 따른 이용의사를 조사하였으며, 이를 토대로 순서형 로짓 분석을 활용한 택시환승할인 이용의향 모형을 구축하여 정책에 미치는 주요요인을 파악하였다. 분석 결과 택시환승 할인 결제수단을 교통요금 지불의 대다수를 차지하는 후불교통카드(신용카드)를 제외한 것이 이용률 저조의 가장 큰 요인이며 향후 후불교통카드까지 혜택 확대 시 잠재수요가 극대화될 것으로 보인다. 또한 택시환승할인 이용에는 결제수단, 통행목적, 주교통수단, 1주일간 택시이용횟수, 연령대, 한 달 교통비, 택시환승할인요금 순으로 영향을 미치고 있는 것으로 파악되었으며 택시환승할인요금 변동에 따른 수요의 가격탄력성을 조사한 결과 1,550원까지는 택시환승 할인금액 증가대비 적정 이용수요 증가를 기대할 수 있을 것으로 분석되었다.

For the survival data analysis of no covariate the discount survival model is proposed to estimate the time-varying hazard rate and the survival function recursively. In comparison with the covariate case it provide the distributionally explicit evolution of hazard rate between time intervals under the assumption of a conjugate gamma distribution. Also forecasting of the hazard rate in the next time interval is suggested, which leads to the forcecasted survival function.

This study investigated the effects of influencing factors on the sales volume of apparel products. Based on previous studies, weekend effect, discount rate, and meteorological factors including daily average temperature, rainfall, sea level pressure, and fine dust were selected as independent variables to calculate their effects on sales quantity of apparel products. The daily sales data during 2015 - 2016 were collected from casual brands and outdoor brands which "A" apparel manufacturing company had operated. The actual data of "A" company were analyzed using SAS(R) 9.4 and SAS(R) Enterprise Miner 14.1. The results of this study were as follows: First, the influencing factors on total sales volume of apparel products were proved to be the weekend effect, discount rate, and fine dust. Second, the analysis of influencing factors on sales volume of apparel products according to season showed: 1) In casual brands, the average temperature had a significant influence on the sales volume of spring/summer products, and the sea level pressure affected the sales volume of summer/fall/winter products significantly. 2) In outdoor brands, the average temperature and the fine dust had a significant influence on the sales volume of all season's products. The sea level pressure affected the sales volume of summer/fall/ winter products significantly. The weekend effect and the discount effect affected the sales volume of apparel products partly. Third, the effect of rainfall was not proven significant, which was different from the results of past studies.

A study on estimation of the Levelized Cost of Energy (LCOE) was conducted for the Korean onshore wind farms. The LCOE was estimated on the basis of the actual wind farm data from Data Analysis, Retrieval Transfer system (DART) run by Financial Supervisory Service. Recently, social discount rate of Korea dropped from 5.5% to 4.5%, which was taken into account for this study. The onshore wind farms studied accounted for 42% of all the onshore wind farms of South Korea. Capital Expenditure (CapEx) and Operation Expenditure (OpEx) were calculated from the actual data, while Capacity Factors (CFs) were obtained from the wind farms of five provinces. Their distributions were estimated using Maximum Likelihood Estimation method, and then Monte Carlo Simulation (MCS) was performed for estimating LCOE, Levelized Fixed Cost (LFC), and Levelized Variable Cost (LVC). As a result, the LCOEs at the two discount rates, 4.5 and 5.5%, were 142 and 152 $/MWh, respectively, which were lower than that of financially viable onshore wind project of Korea. The 1% drop of social discount rate was estimated to result in a 10 $/MWh decrease in LCOE and a 4 $/MWh in LFC, which can be an advantage for wind project investors.

The purpose of this paper is to investigate economic feasibility of creating artificial tidal flats using cost-benefit analyses. We assumed that the cost factors are associated with designing, construction and monitoring, and the benefit factors are associated with fisheries production, habitation, prevention of disasters, water purification, aesthetic value and existence value. First, for analyzing economic feasibility, the scenario suggests that a design can be made in a year, construction can be completed in three years and monitoring must be made for 20 years. Assuming the discount rate of 7.5%, economic feasibility analyses showed that B/C was 2.26 and IRR was 14.50. This study indicated there is economic validity of implementing creation of artificial tidal flat. In addition, we carried out a sensitivity analysis at the change of discount rate and restoration rate. The result of sensitivity analysis clearly showed that economic validity is low when discount rate is over 15%, and changes in restoration rate did not significantly effect on the economic validity.

This study examined: 1) the effects of fashion luxury product price discounts in social commerce on perceived benefit and purchase intention, and 2) differences in such effects by social commerce trust, brand and design preferences for luxury products as well as social commerce and online luxury product purchase experiences. Three discount rates representing high, mid, and low for a luxury product sold in social commerce were manipulated and tested on female consumers and 486 online responses were analyzed. The results revealed that the price discount affected perceived benefit but did not affect purchase intention. Benefits were highly perceived at high and mid discount rates compared to the low rate. Social commerce trust, brand preference, and design preference affected perceived benefit and purchase intention, but the interaction effect with price discount was observed only in the design preference to perceived benefit. The purchase experience of online luxury products also affected purchase intention. Implications from the results were also discussed.

An economic appraisal of a proposed marine ranching project is analysed using capital budgeting model such as net present value(NPV) and internal rate of return( IRR) as well as sensitivity analysis and goal seeking model. Of the factors for economic appraisal, direct benefits are to be determined by estimated harvest, prices and costs incurred by catching fishes, and indirect benefits include the additional economic effect of recreational fishing. And judging the worth of these project options depends upon the choice of discount rate of which 8.5% is recommended here. On the basis of estimated production, prices and costs the project is expected to yield NPV=615 million won and IRR=8.8%, which is quite accepted for an economic feasibility, under the first scenario, and NPV= -127 million won and IRR=7.93%, which is rejected, under the second scenario. Sensitivity analysis has been performed by calculating the switching value and sensitivity indicator in respect of the main project parameters. The results suggest that the project NPV and IRR are especially sensitive to fishes(rock fish and other rock fish) prices and fixed costs. Finally goal seeking analysis is carried out in order to reach a desired level of performance like NPV=0 in respect of the amount of hatchery-reared juverniles, the prices and the discount rate.
