In this paper, we explore the economic principle behind the revenue-sharing rule for interconnection charges. First, we assert that firms can collude by splitting tile revenues equally i.e., choosing the revenue-sharing ratio equal to l/2. Also, we characterize the optimal revenue-sharing ratio in a model of horizontal interconnection and discuss the relation between the optimal ratio and the optimal access price.

This paper investigates whether the value relevance of unbilled revenue in the construction company is differentiated according to the degree of company's operational efficiency. Unbilled revenue is an item that appears in the assets of the statement of financial position based on the IFRS. It is an item that has a nature of accounts receivable, but it is calculated based on subjective judgment of management. In this paper, we hypothesized that the value relevance of unbilled revenue will be differentiated according to operational efficiency of the construction company. The results of hypothesis test are as follows. First, unbilled revenue has a significant relationship with firm's value, which is consistent with previous research results. Second, the value relevance of unbilled revenue is higher in companies with high operational efficiency. In conclusion, this paper is different from previous researches in that this paper presents not only that unbilled revenue has a value relevance but also provides evidence that it can be differentiated according to the degree of operational efficiency.

The metaverse platform has been gaining popularity since the pandemic. It facilitates non-face-to-face interaction among creators, users, advertisers, various forms of organizations, and itself. Such interaction has brought light to the new forms of economy, which is called the "creator economy." By providing the virtual space, easy tools, and methods, the platform allows the creators to produce value for the users in the forms of virtual items, content, and experiences. At the same time, it provides audiences to the organizations that need attention. In the course, the platform and the creators generate revenue. Among the diverse revenue sources, this study focuses on revenue generated from advertising and studies how the revenue sharing between the platform and the creator is affected by the abilities of the metaverse platform. With an analysis of the analytical model, we show that if the platform has the ability to reduce advertising avoidance, it can reduce the revenue share of the creator without discouraging the creator from making the proper effort in content creation. Also, as the platform provides effective tools and methods for quality content creation, it can reduce the revenue share of the creator without damaging the creator's required motivation. The ability of the platform in increasing advertising effectiveness helps it to reduce the revenue share of the creator as well.

In this study, we analyzed how the revenue water ratio(RWR) is affected by changes in conditions of the water supply area, such as the ratio of aging pipes, maintenance conditions, and revenue water. As a result of analyzing the impact of pipe aging and maintenance conditions on the RWR, it was confirmed that the RWR could be decreased if the pipe replacement project to improve the aging pipe ratio was not carried out and proper maintenance costs were not secured. It was also confirmed that an increase in the revenue water could be operated to facilitate the achievement of the project's target RWR. In contrast, a decrease in the revenue water due to a population reduction could affect the failure of the target RWR. In addition to analyzing the causes of variation in the RWR, the calculation of estimated project costs was considered by using leakage reduction instead of RWR from recent RWR improvement project cost data. From this analysis, it was reviewed whether the project costs planned to achieve the target RWR of the RWR improvement project in A city were appropriate. In conclusion, the RWR could be affected by variations in the ratio of aging pipes, maintenance conditions, and revenue water, and it was reasonable to consider not only the construction input but also the input related to RWR improvement, such as leakage reduction, when calculating the project cost.

This paper presents an efficient algorithm for evaluating the Profit and revenue of generating units in a competitive electricity market based on the probabilistic production costing technique. The accurate evaluation of the profit and revenue of generating units for long-term perspectives is one of the most important issues in a competitive electricity market environment. For efficient calculation of the profit and revenue of generating units under the equivalent load duration curve(ELDC), a new approach to figure out the marginal plants and the corresponding market clearing prices during a time period in a probabilistic manner is developed. The mathematical formulation and illustrative application of the suggested method is presented.

This study applied Data Envelopment Analysis to a set of Korean Public Corporation Medical Centers and Japanese Municipal Hospitals to compare their relative human resource efficiencies. Based on the data provided on the inputs and outputs, the analysis showed Japanese municipal hospitals were relatively efficient than Korean hospitals. The result of analysing BCC model shows 5 hospitals in Japan and 7 in Korea with an efficiency rating of less than 1 as considered relatively inefficient. For the inefficient hospitals the manner in which inefficient hospitals may be made efficient were indicated by the managerial strategies based on dual variables. A subsequent analysis of Wilcoxon rank-sum test revealed that the medical revenue per medical expense, labor cost per value added revenue were statistically significant between efficient and inefficient Korean hospitals and medical revenue per medical expense, labor cost per value added revenue, bed occupancy rate, average length of stay, rate of personnel expenses per medical revenue were statistically significant between efficient and inefficient Japanese hospitals.

Transmission pricing is one of important issues related to competitive electricity markets since rational pricing scheme ensures a fair competition between this market participants. Transmission pricing scheme is classified briefly into marginal cost pricing and embedded cost pricing. In economic efficiency, marginal cost pricing is more adequate for competitive electricity market. However, this pricing scheme requires revenue reconciliation since it cannot ensure full recovery of Transco's revenue requirements. This paper presents a new revenue reconciliation to maximize social welfare. For this analysis, this paper provides the results applied by various revenue reconciliation methodologies.

This study is to help international traders in conducting tax and accounting works as to revenue recognition when a shipment incurs in accordance with Incoterms 2010. It is true that some are well familiar with Incoterms but have lack of accounting and tax application. In respect of tax operation, there are several regulations, such as Income Tax Law, VAT Law, which are applied differently according to sales points. Sales points and revenue recognition are a bit different when sales are made internationally. And this study compares those revenue recognitions by comparison of related Korean laws and Incoterms 2010.

Restaurant managers seeking to maximize revenue should look carefully at how long their tables are occupied and how much the average diner spends. This study examined the effect of the customer's party size on restaurant revenue. The dining periods were divided into 2 types (lunch vs. dinner/weekdays vs. weekends), which were combined to show the average spending per minute (SPM), to determine if the dining periods have measurable effects on the dining duration and average bill. The results show that the dining duration for dinner was much longer than that for lunch and there was no significant difference in dining duration between weekdays and weekends. On the other hand, customers in larger parties at lunch time had a higher SPM than those in smaller parties. A larger customer party size was associated with a longer dining duration for dinner and on weekdays. During all operating periods (lunch, dinner, weekdays, weekends), the party size had a significantly positive effect on the mean spending per minute. For restaurant managers, these findings suggest opportunities to increase revenue and adopt revenue management strategies.
