본 연구에서는 경영자의 투자의사결정을 중심으로 하여 조세전략과 투자효율성 간의 관계를 분석하고자 한다. 구체적으로, 경영자의 조세회피 행태가 기업의 투자수준에 미치는 효과를 살펴보고자 한다. 분석 결과, 경영자의 조세회피 수준이 높아질수록 기업의 과잉투자가 증가하는 결과를 보였다. 이는 조세회피로 인하여 증가한 기업의 가용자금이 과잉투자로 이어진다는 것을 의미하며, 조세회피를 통한 가용자금의 증가분이 경영자의 기회주의적인 목적을 위해 이용되어지는 것으로 해석된다. 지금까지의 선행연구를 살펴보면, 기업의 조세전략이 기업가치에 미치는 영향에 대한 분석에 앞서 그 메커니즘에 대한 연구가 선행되어야 함에도 불구하고 기업가치에 영향을 주는 경영자의 의사결정들과 조세전략과의 관련성을 본 연구는 드물다. 따라서 본 연구는 경영자의 핵심적인 행태 중 하나인 조세전략이 기업의 실제 투자의사결정에 미치는 영향에 대한 구체적인 결과를 제시하였다는 점에서 공헌점이 존재한다. 즉, 투자자와 세수를 확보하고자 하는 정부는 경영자의 조세회피 행태가 투자행태에 미치는 영향을 감안하고, 경영자의 조세회피 행위에 보다 경각심을 기울이게 할 것이라고 기대된다.

Purpose - The study analyzed 90 online firms worldwise and observed them for ten years to investigate their investments and firm performance variabilities. This study attemped to verify the existence of agency problems in online firms. Through this, the paper intends to expand the scope of research in the fields of investment and firm value both empirically and in theory. This study also attempted to supplement the insufficient logic of previous studies by analyzing the relationship between investment and profitability. Design/methodology - In this study, the investment is subdivided into over-, under-, and neutral investments, and an empirical analysis of the firm performance was conducted. As investment generally has long-term effects, the impact of a firm's investment on future firm performance and variabilities in firm performance was considered over the short-and medium-term period. Findings - It was found that there was a negative relationship between firms with an overinvestment and future firm performance. Underinvestment has no clear statistically significant results on firm performance. This implies that overinvestment causes more reduction in future firm performance than underinvestment. It was also found that underinvestment and overinvestment significantly increased the variability of firm performance. A positive significance was found between under- and over- investment with a variability of 3 years and overinvestment with a variability of 4 years in the future. A negative relationship was found between neutral investment propensity and future performance variabilities. Neutral investment has less effect on the future performance variability of a firm than a firm's overinvestment and underinvestment. For online firms, underinvestment and overinvestment have a greater effect on the firm's future performance variability than neutral investment. Originality/value - The agency theory predicts that information asymmetry and adverse selection problems exacerbate conflicts of interest among stakeholders, thus firm performance. The study contributed to accumulating research on online firms that are currently underexplored by analyzing the investment behavior of major firms in the online industry.

이 논문은 통신서비스의 규제정책이 역무통합이라는 규제정책의 변화와 함께 과거의 수직적 규제에서 수평적 규제체제로 바뀜에 따라 기존의 개별규제체제가 어떠한 형태로 변할 것이며, 이에 따라 통신망 투자에 어떠한 영향을 미칠 것인가를 분석한다. 역무통합은 진입규제와 행위규제를 분리하여 진입의 제약을 축소하고 행위규제의 유연성을 제고하는 효과를 가진다고 볼 수 있다. 따라서 역무통합 자체가 주는 직접적 효과보다는 상호접속 규제, 설비제공제도, 요금규제, 결합판매, VoIP 번호 이용 등 역무통합과 연계된 행위규제 개선을 통해 간접적으로 시장 파급효과가 나타날 것으로 예상된다. 본 논문에서는 먼저 기업수준에서 투자의사결정에 영향을 미치는 요소들에 대해 논의하고, 진입규제 완화, 상호접속, 요금규제, 망중립성 등의 개별규제가 투자결정에 미치는 영향경로를 분석한다. 마지막으로 정책에 대한 기본적인 가이드라인을 제안한다.

Purpose - As the U.S.-China trade war has become considerably worse, the Chinese government is considering applying non-tariff barriers to trade, especially local contents rule. The main purpose of this research is to check whether it is suitable for Korean investors to invest in the current Chinese capital market. Design/methodology - In order to check the stability of the recent Chinese capital market, we investigated the behavior of foreign equity investment (including Korean equity investment) in the Chinese capital market after China announced the Shanghai-Hong Kong Stock Connect (SH-HK Connect). In this paper, we researched whether international portfolio investment would or would not contribute to an increase the volatility of an emerging market's stock market (Chinese capital market) when foreign investors make investment decisions based on the objective of short-term gains by rushing into countries whose markets are booming and fleeing from countries whose markets are falling. Findings - The empirical results indicate that foreign investors show strong, negative feedback trading behavior with regard to the stock index of the Shanghai Stock Exchange (SSE), and when the performance of foreign investors in the Chinese stock market was fairly good. Also, we found evidence that the behavior of foreign investors significantly decreased volatility in SSE stock returns. Consequently, the SH-HK Connect brought on a win-win effect for both the Chinese capital market and foreign investors. Originality/value - It appeared that the Chinese capital market was very suitable for Korean investors after the China's declaration of the SH-HK Connect. However, the win-win effect was brought on by the Chinese government's aggressive capital control but the capital controls could possibly cause financial turmoil in the Chinese capital market. Therefore, Chinese reform in industrial structure and the financial sector should keep pace with suitable capital control policies.

CEOs Overconfidence can bring potentially risky early decisions to businesses, along with large enterprise free cash flow that can bring different investment decisions with CEOs Overconfidence. Especially in the context of Vietnamese enterprises, CEOs are often influenced by behavioral psychology about overconfidence in investment decisions (due to individual cultural characteristics as well as operating financial markets also depend on many factors outside the market). Therefore, the authors study the impact of overconfidence and cash flow on investment in Vietnamese to find the internal relationship between these three factors in the financial environment in Vietnam. With 480 companies listed on the Vietnam Stock Exchange from 2014 to 2018 (companies have continuous reports), the regression analysis results with panel data (FEM, GLS models, correction of robust and GMM dealing with endogenous problems) have shown Overconfidence has a positive impact on investment. At the same time, the results also indicated that enterprises with overconfident CEOs and large cash flows tend to invest less than enterprises with low cash flow. The results of this study have shown the behavioral behavior of CEOs in Vietnamese enterprises that exist under both prospect theory and effective market theory.

This study recognizes that there is a correlation between the movement of the financial market and the sentimental changes of the public participating directly or indirectly in the market, and applies the relationship to investment strategies for stock market. The concerns that market participants have about the economy can be transformed to the search terms that internet users query on search engines, and search volume of a specific term over time can be understood as the economic trend of big data. Under the hypothesis that the time when the economic concerns start increasing precedes the decline in the stock market price and vice versa, this study proposes three investment strategies using casuality between price of domestic stock market and search volume from Naver trends, and verifies the hypothesis. The computational results illustrate the potential that combining extensive behavioral data sets offers for a better understanding of collective human behavior in domestic stock market.

The purpose of this study is to examine an organizational ICT(Information and Communication Technology) performance by ICT investment and policy consistency of government organizations. As the rapid development of ICT is becoming an essential element of social culture, the ICT operation of bureaucratic government also is becoming important. The central government has invested substantially new ICT for improving the quality of nationwide service and to promote administrative efficiency. However, various departments of government occur frequently duplication investments of ICT, and budget conflicts between organizations caused difficulties in maximizing ICT competency. I will confirm the ICT operational performance by ICT investment behavior and organizational work competency as well as the significance of ICT policy consistency. The method of study used a structural equation. The research model set ICT investment behavior as independent variables, organizational work competencies and policy consistency as mediations, and operational performance as dependencies. As a result of the research, New ICT interests show negative effects that caused work change between government organizations and government-funded body. But, New ICT convergence shows positive effects on increasing the two competency variables. The two competency variables show negative effects that caused changes in ICT policy consistency and show no impact on the ICT operational performance. The ICT policy consistency shows a positive effect on enhancing ICT operational performance. The study contribution explain updated the contingency theory and because the ICT policy consistency is essential, negotiation between government organizations will be important. Future research will require a qualitative study through interviews in government organizations about consistency enhance of ICT policy.
