Assume a company sells two products (a and B) in a retail market. the company adopts a specific promotion mechanism, Tie-in Promotion, in which product A's promotional discount coupon is distributed whenever a consumer purchases product B. Product A will later e sold at a markdown price when consumers eventually take the opportunity to redeem the coupon. in the integrated tie-in promotion and stocking policy, we assume managers of two products coordinate by sharing information on the demand forecast and deciding the order quantities and tie-in promotion program to maximize joint profits. The optimal integrated tie-in policy is analyzed. The integrated tie-in promotion model is then compared with two other base models: (1) a decentralized Newsboy model in which no promotion is considered, and (2) an individual promotion model in which managers design a promotion program to promote one of the two products directly. The factors that make an integrated tie-in promotion a better approach are studied.

최근 들어 온라인 쇼핑몰과 SNS(Social Network Service)가 결합한 새로운 쇼핑방식인 소셜쇼핑(social shopping)과 소셜커머스(social commerce)가 핫이슈가 되었다. 소셜커머스는 이전에 존재하지 않던 수요를 창출해 낼 수 있다는 점에서 공동구매와는 전혀 다른 새로운 상거래방식이다. 소셜커머스는 50% 이상의 가격할인율과 특정 거래조건(품목, 거래가능 시간, 사용기간, 물량 등)의 제약을 통해 관심의 경제(economy of attention)를 극대화한 수익모델이라 할 수 있다. 본 연구에서는 소셜커머스에서 가격할인과 소비자들의 제품에 대한 지각된 위험은 충동구매에 어떤 영향을 미치는지에 대해서 검토하고자 하였다.

There has been a need for the systematic evaluation of the economic efficiency between conventional fluorescent lamp lighting systems that have been used in tunnels and LED lighting systems. This study has evaluated basic tunnel lighting between the conventional fluorescent lighting systems and the LED lighting system using the evaluation tool of tunnel lighting by Life Cycle Cost (LCC) and using the economic efficiency evaluation method. In addition, the unit discount rate of the LED lighting system and the estimated increase in the price of electricity have made the estimated cost of LCC the same if two luminaires were used in the basic part of the tunnel.

Results of a study of the coordination effect in stocking and promotional markdown policies for a supply chain consisting of a retailer and a discount outlet (DCO) are reported here. We assume that the products are sold in two consecutive periods: Normal Sales Period (NSP) and subsequent Promotional Sales Period (PSP). When managers in the two periods coordinate, they share information on the demand forecast and jointly decide the stocking quantity, markdown time schedule, and markdown price to maximize mutual profit. In the absence of coordination, decisions are decentralized to optimize the individual party's objective function. Optimal coordination policy for the retailer/DCO problem setting is analyzed, and the coordination policy is compared with the uncoordinated policy to explore factors that make coordination an effective approach.

This study examined the practice of the impulsive purchase and the factors influencing it among college consumers. The data were collected from 481 college students in Busan and Gyeongnam areas through a self-administered questionnaire. Frequencies, Cronbach's alpha, factor analysis, Pearson's correlation analysis, and regression analysis were conducted by SPSS Windows. The results from this study were as follows: First, the level of the impulsive purchase of college consumers was not that high. Second, as a result of regression analysis for the group of the high level of impulsive purchase, the allowance amount, price-discount factor, credit card use, psychological factor, and attitudes towards money (ostentatious way, and symbol of success), affected the impulsive purchase. These results suggest that consumer education regarding values about money and strategies to resist impulsive purchase should be conducted at home and in school.

We address the problem of choosing the most economic mean value for an automatic filling operation on a production line through the sampling inspection. If quality characteristic of a unit is less than inspection specification then the goods is not accepted. Otherwise, it is accepted. The lots that the numbers of non-conforming units in a sample are larger than the allowable number of non-conforming units are rejected. The non-conforming units in the rejected lots are separated by the screening inspection. The non-conforming units separated are sold in discount price. We assume that quality characteristic is larger-the-better characteristic, the distribution of quality characteristic is normal distribution, and the standard deviation of the distribution is known. This paper presents total expected profit function model considering sales revenue, inspection costs, and material costs. The manufacturing process mean value maximizing total expected profit is determined, and the results of the process target value and total expected profit is analyzed as coefficients change.

Educational programs for students with intellectual disabilities have undergone drastic changes in pursuit of the general curriculum. Accordingly, teachers in various fields, including mathematics, strive to find effective methods that enhance learning. The objective of this systematic review is to examine the field of teaching mathematics to students with intellectual disabilities to investigate relevant effective teaching strategies and required teaching skills. To achieve this goal, studies published during the period 2018-2021 were reviewed. Findings indicate the inclusion of nine studies that met the inclusion criteria out of 55 studies. The included studies found that the system of least prompts (SLP) in conjunction with feedback and error correction, and schema-based instruction are generally the most effective strategies in teaching mathematical skills to students with intellectual disabilities. Addition is the most targeted skill, followed by subtraction and algebra problem solving. The least targeted skills are multiplication, recognition of geometric shapes, calculating price after discount, rapid recognition of numbers, and rapid problem solving. The paper provides recommendations and suggests venues of future research.

As an increasing number of people gained access to social network services (SNS), organizations started to use SNS as a channel for marketing and promotional purposes. The online advertising market has significant growth potential. Brand engagement is a key motive for online advertising, but how SNS users engage with brands, particularly in terms of the promotion of organizations, is poorly understood. This study uses customer value theory to examine brand engagement of users in terms of promoting companies in the context of Korean SNS marketing. This study identifies the antecedents of brand engagement based on customer value theory. Our findings show the significance of three factors of SNS marketing, namely, price discount, relationship support, and convenience, on brand engagement. We further show the consequences of brand engagement, namely, purchase decisions and word-of-mouth activities. These findings help advance customer value theory and offer practical insights into the use of information systems and marketing in the context of SNS.

Since service competition among global supply chains became intensified, market-oriented system, instead of the existing cost-based system, for port service pricing has been strongly recommended in order to enhance their long-term viability and competitiveness. The Owen value of cooperative game frameworks allows us to apply a market-oriented pricing theory for the port pricing in the case of Gwangyang port to verify its usefulness. The analytical results of this paper suggested some solutions in the problem of berth-based cost allocation by a characteristic function and also showed the proper relative weights of factors to derive the quay use index by Budescu(1993). We also suggested a favorable port pricing system to major shipping firms as well as a discount port pricing system for their strategic alliance. To put it differently, the results of this study enable the port managers to make out some strategic port pricing system like the reasonable discount in port charge for the larger ship owners using the ports frequently.
