With the exponential spread of Mobile phones, Mobile social network game (hereafter “MSNG”) market is rapidly growing. Service provider of MSNG could enjoy enormous success of fast spreading market growth of MSNG, while they have to endure the short product life of its service. Considering the MSNG business model has been anchored on the item sales and online advertising, the goal of MSNG operators focuses on the exposure of customers which could be obtained by enlargement of network size. In MSNG business, a phenomenon that requires the customer to act as a salesperson has been identified, while the word-of-mouth and the customer loyalty have been emphasized in conventional marketing discipline. Customers who propose acquaintances to use MSNG would receive rewards for their role as a part time salesperson. While WOM and recommendation share the non-commercial characteristics, acquaintances recommendation in MSNG business can be considered as a method to covert customer into its in-house salesperson. In this paper, we assume the goal of MSNG service provider as the enlargement of customers’ act of proposing its MSNG to their acquaintance (i.e., NPS: net promoting customer). With the improvement of NPS, MSNG service provider can harvest the opportunities to the extension of network size and its internal transactions. We anchored TAM model to elaborate acquaintance recommending action of MSNG users. By mediating variable of “Ease of use” and “Reputation”, “Emotional value” and "Functional value" have been considered to elevate NPS.

미국판례를 중심으로 한 회사의 재정적 무능력 주장의 검토

강태훈 ( Tae Hoon Kang ) 법조협회 2012 法曹 Vol.61 No.8

In case corporation brings suit against corporate officers or directors alleging that they usurped a business opportunity belonging to the corporation, they often try to defend themselves by asserting that the corporate opportunity doctrine (hereinafter ``COD``) is not applicable if an opportunity is one which the corporation is financially unable to undertake. On April 14. 2011. COD was legislated into the Korean Commercial Code. However the new article of corporate opportunity does not provide the financial inability defense. leaving it to the hands of case law or scholars. Basically there is no logical necessity between financial inability defense and the standards of COD, But studying the main cases which dealt with the financial inability defense, I could find that those cases closely related to the seminal cases which generated the corporate opportunity tests, given some guidelines how to cope with the defense Thus I classified the main cases according to those seminal cases which influenced on them and approached all those cases systematically to find out their positions and their rationale of them about the three issues generally debated in the financial inability assertion, viz., ① Could such defense be recognized ? ② If so, is it required that the corporation be insolvent rather than merely financially distressed ? ③ Is the burden of the proving financial inability rested on the fiduciary or the corporation ? Additionally I reviewed Korean scholars` opinions about those things and set forth my view.

논문은 MSNG 사용자들의 지속적 이용을 장려하고자 하는 MSNG 서비스 제공자들의 전략에 대하여 연구하였다. 이를 위하여 MSNG 사용자들의 행동에 영향을 미치는 심리의 작용을 이해하고자 하였다. MSNG서비스 제공자는 MSNG 사용자의 이성적, 감정적, 심리적 측면을 공략하고자, MSNG 사용자가 인지하게 될 기능적 가치, 감성적 가치 및 사회적 가치 향상 전략을 실행할 것으로 가정하였다. 또한, 이러한 MSNG 서비스 제공자의 전략이 MSNG 사용자의 심리적 상황을 몰입 상태로 바꾸어 MSNG에 대한 지속적 사용의도가 나타날 것으로 추론하였다. MSNG 사용자들로부터 확보된 431개 응답을 기초로 분석한 결과에 따르면, MSNG 서비스 제공자가 사용자의 기능적 가치, 감성적 가치 및 사회적 가치를 높이려고 하는 전략은 모두 MSNG의 지속적 이용에 직접적인 영향을 미치는 것으로 분석되었다. 또한, MSNG 서비스 제공자의 제반 가치 향상 전략은 MSNG 사용자의 심리적 상황을 몰입 상태로 변환시켜 지속적 이용을 강화하는 것으로 분석되었다. 상기와 같은 결과를 바탕으로 시사점을 제시하고, 연구과정에서 직면한 한계점을 기반으로 향후 연구방향을 제언하였다. This paper explores the framework in which MSNG(Mobile social network game) service providers' strategies to enhance users' intention of continuous usage. Users' perceived values have been considered as the key factors to solicit MSNG user's intention. Moreover, we suggest flow(user's psychological immersion to MSNG) as a mediator variable to inflame users' intention. Results based on 431 respondents shows that MSNG service providers' strategies(i.e., functional, emotional, and social values) directly influence users' intention to use, while those independent variables also show positive relationships towards dependent variables. So we can identify that the efforts to elaborate the users' perceived values are meaningful strategies of MSNG service providers. Also, user's psychological change(i.e. "flow" in this study) is the essential to mediate between MSNG service provider's strategies and building users' intention to use for that MSNG.

농산물 가격 위험관리와 밭떼기거래의 개선방안

강태훈(Tae Hoon Kang) 한국농업경제학회 2000 農業經濟硏究 Vol.41 No.3

The fact that the `Battegi` contract, a kind of agricultural forward contracts, is one of probabilistic investment games has not been well recognized. Sellers(Buyers) of `Battegi` contracts have rights(obligations) to sell(buy) products at higher price than market price when harvest price is lower than expected, or have obligations(rights) to sell(buy) at lower price than market price when harvest price is higher than expected. The rights and/or obligations from the contracts must be completed so that the contracts can be used as price risk management tools. One way for the contracts to be completed is to make sure the completion by installing stronger commitments(that is, to make it virtually forward contracts), or another way is to raise upfront fee for the contracts high enough to compensate the high volatility of agricultural product prices(that is, to make it as an option).

축산물 가격의 비대칭전이에 관한 실증연구

강태훈 ( Tae Hoon Kang ) 한국식품유통학회 2011 食品流通硏究 Vol.28 No.2

If prices in the later (earlier) stage of marketing channel respond faster or deeper to the price increases in the earlier (later) stage of marketing channel than to decreases, we call it the positive (negative) APT. This paper considers four major livestock prices such as beef, hog, chicken, and egg prices in Korea. Potential APTs are tested for the stages from farm to wholesale as well as from wholesale to retail using daily prices. Since the prices in each marketing stages are cointegrated each other, the asymmetric error correction model is used. Beef market shows the positive APT in both cases, that is, farm to wholesale and wholesale to retail. Hog and egg markets show the positive APT in wholesale to retail case, while chicken market shows no APT. These results support for the customers` complains thus far that retail price rises fast when farm price rises but doesn`t fall or falls slow when farm price falls.

몬데카를로시뮬레이션방법을 이용한 옵션가격 수렴성에 관한 실증연구

강태훈(Tae-Hoon Kang) 한국국제회계학회 2006 국제회계연구 Vol.0 No.15

본 연구의 목적은 옵션가치평가의 한 방법인 블랙-숄즈 옵션가격결정모형과 몬테카를로 시뮬레이션을 이용한 옵션가치평가의 비교를 통하여 전통적인 모형인 블랙-숄즈 옵션가격결정모형과 별다른 차이가 없음을 보이고자 하는 논문이다. 블랙-숄즈 옵션가격결정모형은 1973년에 제시되어진 모형으로서, 현재까지 옵션의 가치를 평가하는데 일반화 되어진 모형이며 최근 들어 만들어지고 있는 다양한 옵션의 가치를 평가하는데도 유용하게 사용되고 있다. 하지만 블랙-숄즈 옵션가격결정모형은 이론적으로는 가장 완벽한 모형으로 간주되지만 모형을 위한 가정이 비현실적이고 개별요소의 특성을 달리 나타낼 수 있는 여지가 많다. 그리고 각 변수들의 양이 많아져 복잡한 식으로 된다면 해결하는데 많은 시간과 노력이 소요되는 단점이 있다. 이러한 단점을 보완하기 위한 방법이 Monte Carlo Simulation이다. 몬테카를로 시뮬레이션은 블랙-숄즈모형의 기초가 되는 여러 가정들이 완화되어 옵션가격을 결정하는 공식의 적용이 불가능하고 옵션가격을 결정하는 변수의 앙이 많아서 일반식 형태로 풀기 난해한 경우 옵션가격을 산출하는 방법이다. 본 논문의 실증분석결과 t-검정 값들이 모두 귀무가설을 채택하여 결론적으로 블랙-숄즈 가격결정모혈과 몬테카를로 시뮬레이션을 이용한 옵션가격결정모형의 관측 값은 유의적으로 같음을 알 수 있다. This paper uses a Monte Carlo simulation for option valuation problem, compares the solutions by a Monte Carlo simulation with those by a closed-form function based on the Black-Scholes option pricing model and prove that the method is efficient as well as simple and flexible in the sense that it can be easily modified to accommodate different processes governing the underlying instruments movements. Designed by Black and Scholes in 1973, the option pricing model succeeded in drawing general formulas with relatively simple assumptions and thereby various option pricing models were developed. The option pricing model, Black-Scholes Model has developed by the repetitive relaxation and alternation of assumptions. meanwhile, the output of integration has become too complex to draw an analytic solution. To solve such problem, numerical approaches were introduced. One of the typical numerical approach is the Monte Carlo Simulation. The simulation can include various stochastic processes which determine the profit of underlying assets, and thus the simulation is commonly used to the option pricing. The paper shows that some conditions are needed in order to converge random prices into a stable status in the simulation. The drawback of the Monte Carlo method lies in the fact that the standard deviation error of estimate is inversely proportional to the square-root of the number of simulation trials. Technique for improving the efficiency of the method is the antithetical method that can reduce variances. The total standard error is significantly reduced using the antithetical method. The antithetical method calculates two values of option price, one being calculated in the normal way and the other calculated through changing the sign of the all the samples from standard normal distribution. The average of the two values is considered as the value of the option price from the sample. The final estimate of the value of the option price is the average of all the average of the pairs of values.
