쿠르노 모델은 경쟁적 전력시장을 게임이론 기반으로 모델링하기 위한 대표적인 모델이다. 이전 연구에서도 쿠르노 모델을 이용하여 전력시장을 모델링 하기 위한 다양한 시도가 이루어져 왔다. 쿠르노 모델은 몇 개의 주요 발전사업자들이 경쟁하고 그로 인해 시장지배력이 존재하는 과점 시장모델에 적합하다. 쿠르노 모델로 시장을 모델링함에 있어서는 우하향 하는 수요함수의 존재가 선결되어야 한다. 과점에서 시장참여자들은 시장지배력을 활용하여 그들의 이익을 극대화하려고 노력하지만, 우하향하는 시장수요함수에 의해 매출 역시 하락하기 때문에 적당한 지점에서 이러한 시장지배력의 행사를 제한하여야 한다. 스마트그리드에서는 실시간으로 변동하는 요금제와 다양한 전산기반 툴의 활용으로 인해 이러한 수요반응이 더욱 활성화될 것이고, 이 경우 쿠르노 모델은 수요반응 솔루션의 주요 모델로 활용될 것이다. 이에 본 논문은 실제 시장에서 계량경제학적인 접근으로 전력시장의 수요곡선을 추정하는 방법에 대해 제안한다.

This paper examines quantile dependence and directional predictability between the foreign exchange market and the stock market in Korea. Instead of adopting a multivariate model such as a vector autoregressive model, a multivariate GARCH model or a combination of both models, we apply the cross-quantilogram recently proposed by Han et al. (2016). Considering various quantile ranges, we investigate various spillover effects between two markets. Our findings show that there exists an asymmetric bi-directional spillover between two markets and the interdependence between two markets implies that one market has significant predictive power on the other.

본 논문은 1990년부터 1997년 IMF금융위기가 일어난 시점까지 이루어진 다각화 합병과 비다각화 합병기업들의 M&A사례를 표본으로 하여 합병성과를 분석하였다. 합병성과 측정모형은 시장모형(market model)과 시장조정 수익률 모델(market-adjusted return model)을 그리고 검증은 t-통계량을 이용하였다. 연구결과, 본기간에 발생된 합병성과는 80년대에 비하여 경쟁적이고 보다 자율적인 M&A특성으로 인하여 비다각화합병 기업에게 부(-)의 성과가, 다각화합병기업에게는 정(＋)의 성과로 나타났다.

Competition among electric generation companies is a major goal of restructuring in the electricity industry, The trading system in an electricity market has been one of the most important issues in deregulated electricity market. This paper deals with comparisons of the major two types of the trading system: compulsory pool market and bilateral contract market. The two trading systems are compared quantitatively from the viewpoint of consumer's surplus and social welfare, This paper, also, proposes a unified model of Cournot and Bertrand for analyzing the mixed trading system of pool market and bilateral contract market. Nash equilibrium of the unified model is derived by criteria for participating in bilateral contract market. Numerical results from a sample case show that a mixed trading system of pool market and price-competitive bilateral market is beneficial to consumer from the view points of consumer's surplus.

The purpose of this paper is to investigate the volatility of both Islamic and conventional stock market in Indonesia with the aim of identifying the most appropriate model for risk management practice. The study considers GARCH as a genre of model to measure the volatility of stock market movement. The results support the view that each model shows specific volatility from both Islamic and conventional stock market in Indonesia. In Islamic stock market, volatility is affected by exchange rate and money supply (M1) but not interest rate as interest is prohibited in Islam. However, interest rate is found as a principal factor that affects volatility of conventional stock market. The outcomes of this paper are of particular significance to policy makers, as it provides guidelines to maintain economic health. Furthermore, the findings may assist practitioners to understand the consequences of macroeconomic factors such as exchange rate, money supply and interest rate, which are very crucial for the market stability of Indonesian stock market. The paper enhances the understanding of stock market volatility and proposes guidelines risk management practices.

B2B transaction was expected to dominate in the global market and thus many e-marketplaces have been built since 1999 in Korea. However, only a few e-marketplaces are thriving and the future of B2B e-marketplaces except MRO area seem to be uncertain. This paper explores why B2B transactions only in MRO area are rapidly increasing and examines the competing structure and business models of MRO e-marketplace. Business models of MRO e-marketplaces are various among different countries. However, they can be classified as three business models:information portal model, purchasing agent model, open market model. It is not easy to answer which business model is most competitive because each models have their own advantages and functions. Information portal model can be easily applied for the e-marketplace which operates off-line enterprises. Purchasing agent model is favorable to the e-marketplaces which has already obtained buyers and sellers. Open market model is desirable to the e-marketplace which has excess to global market.
