In storage technology it is desirable to have greater storage capacity at lower costs. Data compression addresses these demands by reducing the amount of data that must be stored to a given size of media, thus lowering the cost of that storage device. In data compressions it is desirable to have faster transfer rates at lower costs. Data compression addresses these demands by reducing the amounts of data that must be transferred over a media with a fixed bandwidth, thus reducing the connection the. Data compression also reduces the media bandwidth required to transfer a fixed amount of data with a fixed quality of service, thus reducing the costs on this service.

Buyers are transforming their relations with suppliers. For examples, Instead of playing off dozens or even hundreds of competing suppliers against each other, many firms are finding it more profitable to work closly with only a small number of ＂partners＂. If will facilitate a move from single-supplier arrangements(＂hierachies＂) to mutiple supplier arrangement(＂markets＂) because it reduces the costs of coordination with suppliers. According to this logic, Technological developments which lower the cost of acquiring information about prices and product characteristics in a given market should increase to the nymber of tends to lower coordination costs, it wide adoption should lead to an increase in the number of suppliers for most firms, other things being equal. An efficient merket is defined a one that reduces the numer of intermediaries, or the number of Intermediary steps necessary of market tracsaction. It is true that one can order some products via mail order, which reduces the number of intermediaries and cuts transaction costs further Similary, the growth of a global commerce nerwork such as the internet may futher reduce the number of intermediary steps necessary for trade.

As electronic commerce establishes itself as a viable and competitive channel, this research compares the attractiveness of online and offline purchase from a transaction cost perspective. In the process, we propose a framework that integrates transaction cost with purchase decision process and product type. Specifically, the paper proposes and tests hypotheses regarding the difference between online and offline channels with respect to the transaction costs incurred in each stage of the purchase decision process. These differences are further compared across different product types categorized according to the FCB Grid. A total of 24 hypotheses were tested by conducting a questionnaire survey on university students. The results showed that 19 out of 24 hypotheses were supported. Following a detailed presentation of the analysis results, the paper concludes by discussing the academic and managerial implications of the findings.

Transactions of updating spatial dta with mobile clients are log transactions because a user disconnected from a server surveys real features and updates them. In this environment, it is appropriate to exploit the optimistic approach based on the validation test in order to control the concurrency of transactions. On the contrary, the pessimistic concurrency control scheme makes transactions wait for a long time due to the lock. In this paper, we propose the surrogate transaction model and implement its manager for the S-S-M(Server-Surrogate PC-Mobile Client) structure which is appropriate for updating spatial data in mobile environments. In the S-S-M structure, the mobile client communicates with the server by the surrogate PC. We extend the validation condition in consideration of spatial relationships between spatial objects in this model. We also present the commit protocol where the user of a surrogate PC adjusts objects of the conflicted surrogate transaction to minimize costs for the abortion of the transaction.

Electronic channel of automobile insurance has emerged as an attractive way of lowering costs and saving time to do the transaction for customers. Electronic channel refers to using web sites to find useful information on insurance products, buy automobile insurance, and ask for services related to the insurance. This study suggests a modified model of the UTAUT and examines the factors influencing intention to use electronic channel in the transaction of automobile insurance. Based on 203 responses from potential automobile insurance buyers, the results showed that performance expectancy, effort expectancy, social influence, service expectancy, and security risk are significantly related to intention to use electronic channel. The results also showed that age as a moderator influences the effects of performance expectancy and effort expectancy on intention to use electronic channel. The study results would improve the understanding of the factors to which managers of insurance companies should pay attention in order to increase their sales through electronic channel.

Faced with the challenge of reducing costs and improving competitive position, firms have recognized outsourcing as an important information systems (IS) strategic option. It has not been understood clearly what determines IS outsourcing. Based on the IS literature and transaction cost economics, cost efficiency related factors were identified, and a questionnaire survey was conducted. The results based on 181 responses from the bank executives in U.S. revealed that vendor production cost advantage and transaction risk are significant predictors of degree of outsourcing and outsourcing preference for data processing services. Insufficiency of IS funds and information technology uncertainty were found to be not only positively associated with vendor production cost advantage, but also directly associated with outsourcing preference and degree of outsourcing. Firm size is, however, not significantly related to vendor production cost advantge and IS outsourcing.

The electric power industries are moving from the conventional monopolistic or vertically integrated environments to deregulated and competitive environments, where each participant is concerned with profit maximization rather than system-wide costs minimization. Consequently, the conventional least-cost approaches for the generation resource schedule can not exactly handle real-world situations. This paper presents a game theory application for analyzing power transactions and market design in a deregulated energy marketplace, where the market participants determine the net profits through the optimal bidding strategies. The demand elasticity of the energy price is considered for the realistic modeling of the deregulated marketplace.

This paper describes a novel approach for allocating transmission costs among users of transmission services. In the suggested approach, the cost share of each participant is proportional to amount of its line flow. To develop individual user's impact, the line utilization factors of each participant are derived by power flow equations of all nodes (i.e., load-flow equations). To deal With the slack bus problem inherent in the conventional load-flow analysis more practically, a additional power supply/demand balance equation is incorporated. Although the developed allocation rule is basically similar to the existing MW-mile method in the aspect of embedded cost allocation, it does not require to get load flow solutions of each wheeling transaction when multiple transmission transactions are considered.

The present study analyzed movie consumption behavior from the perspective of transaction cost, taking into account the possible incurrence of additional costs in the process of consumers obtaining movie information to choose movies. Regression and multinomial logistic regression analyses were performed in the analysis by taking movie information and the individuals' social demographic characteristics as independent variables and the number and frequency of movies watched as dependent variables, using information from the "2015 movie consumer survey." The results showed that consumers considering elements such as "directors" and "online reviews" were found to be more active in movie consumption. The analysis of movie-watching frequency showed that the information considered when choosing a movie was different for high- and low-frequency movie viewers. Putting these factors together suggests that movie consumption can vary according to an individual's cultural capital, preferences, and their degree of movie information awareness. While existing studies have mostly analyzed the determinants of box office performance, the significance of the present study is its empirical analysis of individual movie information in terms of transaction cost. Based on the results above, it can be inferred that the cyclical structure of trading expenses influences movie consumption and, once preferences are formed through a certain level of consumption, the trading cost expenses decrease, which results in increasing consumption. Therefore, film makers need to establish and execute marketing strategies that appropriately use movie information so that consumers can reduce the trading costs necessary for movie watching.
