Purpose - The purpose of this research is to provide insights that can be used for deliberate decision making around challenging big data investments by measuring the economic value of such big data implementations. Research design, data, and methodology - We perform empirical research through an event study. To this end, we measure actual abnormal returns of companies that are triggered by their investment announcements in big data, or firm size information, during the three-year research period. The research period targets a timeframe after the introduction of big data at Korean firms listed on the Korea stock markets. Results - Our empirical findings discover that on the event day and the day after, the abnormal returns are significantly positive. In addition, our further examination of firm size impacts on the abnormal returns does not show any evidence of an effect. Conclusions - Our research suggests that an event study can be useful as an alternative means to measure the return on investment (ROI) for big data in order to lessen the difficulties or decision making around big data investments.

Conventional discounted cash flow techniques fail to capture the risk associated with investments. This paper proposes an annual cash flow model that considers risk, cost structure and inventory liquidation in the evaluation of investment alternatives. The risk differential of investments is included using the capital asset pricing model while the stochastic version of the cost-volume-profit approach is used to consider inventory liquidation and cost structure. Tradeoffs between fixed and variable costs have been investigated, and portrayed using iso-cash flow curves. The proposed cash flow model has been developed, in particular, to enable an accurate evaluation of advanced manufacturing systems.

The purpose of this paper is to put forward a conceptual framework for understanding factors shaping the nature of the relationship marketing using the case study. Through this research, I can suggest it. Companies may monitor customer satisfaction by using questionnaires, general comments, customer complaints, online surveys, suggestion boxes, and personal interviews. The main purpose is to keep up to date with the needs of customers in order to retain them by creating the relationship it wants with the customers. Relationship Marketing is quite expensive, especially, in the initial period. Therefore, effective relationship marketing requires marketers to adopt affordable and practical and profitable approaches that give room to low costs without compromising quality of the product.

The demise of the native franchise markets and the emergence of competitive markets in electricity generation service is substantially altering the way that operation and planning activity is conducted and is making it increasingly difficult for market participants such as generation firms to prospect the future electricity markets. Traditional generation expansion planning (GEP) problems which centrally determine the least-cost capacity addition plan that meets forecasted demand within pre-specified reliability criteria over a planning horizon (typically 10 to 20 years) is becoming no more valid in competitive market environments. Therefore, it requires to develop a new methodology for generation investments, which is applicable to the changed electric industry business environments and is able to address the post-privatization situation where individual generation firms seek to maximize their return on generation investments against uncertain market revenues. This paper formulates a new generation expansion planning problem and solve it in a market-oriented manner.

Dynamic programming is applicable to any situation where items from several groups must be combined to form an entity, such as a composite investment or a transportation route connecting several districts. The most desirable entity is constructed in stages by forming sub-entities that are candidates for inclusion in the most desirable entity are retained, and all other sub-entities are discarded. In the paper, the fuzzy dynamic programming is applied to the situation where each investment in the set has the following characteristics : the amount to be invested has several possible values, and the rte of return varies with the amount invested. Each sum that may be invested represents a distinct level of investment , and the investment therefore has multiple levels. A numeric example constructing a combination of multilevel investments is given in the paper.

This research shows that as the use of IT spreads, the Investments of IT must be accompanied by the innovation of the business process of an organization to increase productivity. It examines closely to the relations between these by presenting a theoretical formula, with related-theories at the basis, that shows the characteristics of IT Infrastructure and heightens the results of organization. In previous researches, various results co-exist in presenting the direct relativeness between IT Infrastructure and results of organization. But in this research, a parameter called business process has been included making it possible to analyze even the indirect effects to the results of organization. Also, the difference and relativity between the IT Infrastructure and business process groups according to the company environment factor has been proved.

Along with continuous increase in international investments encouraged by wide spread bilateral investment treaties (BIT) including free trade agreements (FTA), international investment disputes have been also increasing. This means that a host State, an importer of foreign investments, and a investor who exports its investment to foreign State, need to take measures to prevent international disputes arising from international investment or to prepare for the arbitration for resolving the disputes. Under these circumstances, this paper compares ICSID arbitration rules and UNCITRAL arbitration rules in respect of (i) the institution of arbitration, (ii) the appointment of arbitrators and the composition of arbitral tribunal, and (iii) the procedures for, and the form of, arbitral awards. On base of this comparison, this paper further suggests certain practical issues that the host State's government and the foreign investors should be aware of in order to be ready for the resolutions of disputes by ICSID or UNCITRAL arbitrations.
