Quasi-Monte Carlo method is known to have lower convergence rate than the standard Monte Carlo method. Quasi-Monte Carlo methods are using low discrepancy sequences as quasi-random numbers. They include Halton sequence, Faure sequence, and Sobol sequence. In this article, we compared standard Monte Carlo method, quasi-Monte Carlo methods and three scrambling methods of Owen, Faure-Tezuka, Owen-Faure-Tezuka in valuation of multi-asset European call option through simulations. Moro inversion method is used in generating random numbers from normal distribution. It has been shown that three scrambling methods are superior in estimating option prices regardless of the number of assets, volatility, and correlations between assets. However, there are no big differences between them.

As many companies have adopted and used ERP systems, concerns about ERP performance also have increased. The purpose of this research is to examine the relationships between qualitative variables and quantitative variables measuring ERP performances. Qualitative research, widely used in MIS research, typically examines perceived usefulness of ERP, such as information quality, system quality, system satisfaction. Quantitative research, often done in accounting research, usually examines ERP performance based on financial statements. An empirical study led to the following conclusions: 1) There were significant correlations among the qualitative variables measuring perceived usefulness of ERP; 2) Significant correlations were also observed among the quantitative variables based on financial statements; 3) However, no significant correlations was found between the qualitative variables and quantitative variables measuring ERP performance.

The purpose of this study is to develop an index to measure regional creativity factors from previous research, as well as to empirically analyze the relationship between regional creativity and regional growth. We conduct panel analysis on the balanced panel data of regional creativity in fifteen Korean cities and provinces during 2008-2012. The result of hypothesis testing are as follows: First, amongst factors of regional creativity, sub-factors such as creative personnel and intangible asset (of the basic asset factor), creative enterprise (of the economic agent factor), and convergence and creative industries (of the core industry factor) showed significant influential relationships with GRDP (Gross Regional Domestic Product) as positive. Concerning the systemization factor, all sub-factors showed no significant relationship with GRDP. Second, amongst the factors, creative personnel (of the basic asset factor), start-up and entrepreneurship (of the systemization factor), creative enterprise (of the economic agent factor), the regional space factor, and convergence industry (of the core industry factor) showed significant positive relationships with employment rate. However, tangible and intangible creative asset (of the basic asset factor), convergence management and administration (of the systemization factor), Large/middle/small enterprises and central government/municipalities (of the economic agent factor), and creative industry (of the core industry factor) showed no significant relationship with employment rate. The results of this study will provide insight into the current situation for regional creativity, and review the process and short and long term performance. In addition, it will be a basic means to lead the central government's policy of strengthening local autonomy and decentralization.

This study aims to analyze multiple mediating effects of asset and self-esteem on the relationship between disability of household head and life satisfaction. This study used 9th panel data of KoWePS(Korean Welfare Panel Study) and employed path analysis with A-MOS. Research findings of this study are as follows: First, disability of household head had a negative effect on life satisfaction, total assets, and self-esteem. Second, we found not full but partial mediating effects of assets on the relationship between disability and life satisfaction. Third, similarly we found not full but partial mediating effects of self-esteem on the relationship between disability and life satisfaction. Finally, we found multiple partial mediating effects of assets and self-esteem on the relationships between disability and life satisfaction. The findings of this study suggest that financial education as well as asset management targeting persons with disability are necessary and very helpful to sustain their life satisfaction. In addition, we need to think about asset-building programs targeting persons with disability.

본 연구에서는 미국 상장은행의 자산 부채포오트폴리오 구성의 위험분산(risk diversification)과 도덕적해이(moral hazard)에 관한 실증적 분석을 행하였다. 실증적 분석의 결과 은행의 금기(今期)의 위험분산과 금기(今期) 이후의 위험추구 간에는 유의적인 양(陽)의 관계가 있음을 발견하였다. 즉 위험분산의 정도가 커서 투자가들로부터 파산가능성이 낮을 것으로 여겨지며, 따라서 위험증가에 따른 자본조달비용(예금이자율)의 증가라는 시장에서의 억제기능(market discipline)이 효과적으로 부과되지 못하는 은행들은 이러한 이점들을(특히 시장관련-체계적) 위험성이 높은 정책을 추구함으로써 수익을 증가시키려는 도덕적해이의 동기를 가지고 있음을 알 수 있었다. 선행연구에서의 논리대로 은행규모의 대형화가 자산 부채포오트폴리오 구성의 위험분산을 크게 하는 주요한 원인 중의 하나라면, 본 연구에서의 결과는 은행산업의 불건전한 재무구조와 그로 인한 금융질서의 혼란, 나아가 국가경제 전체의 혼란을 겪고 있는 한국 금융산업의 현주소, 즉 부실은행을 퇴출시키고 인수 합병에 의한 대형선도 은행(leading banks)중심으로 은행산업을 재편하는 한국금융산업의 구조조정에 있어 간과되어서는 안 될 중요한 정책적 시사점을 제시해 주고 있다고 하겠다. 즉 도덕적해이의 감소에 대한 제도적인 유인장치가 없는 단순한 인수 합병에 의한 은행의 자산규모의 증가가 반드시 은행산업의 구조적 안정에 기여할 것이라고 기대할 수는 없을 것이다. 대형은행의 자산 부채포오트폴리오 구성의 위험분산의 이점과 이로 인한 투자가들의 대형은행의 위험추구행위에 대한 감시동기의 부족, 이로 인한 도덕적해이가 필연적으로 발생하는 현상이라면, 도덕적해이의 감소에 대한 추가적인 유인책 없는 단순한 자산규모의 증가는 인수 합병을 통하여 탄생한 대형선도 은행들의 또 다른 도덕적해이를 낳을 가능성이 크기 때문이다.
