Recently economic crisis has brought world economic instability. Each country in order to stabilize the economy, fiscal rules are introduced or reinforced. Fiscal Policy in a country plays an important role in determining the economic situation in the present and future. Existing fiscal rules tend to place a rigid limit not only on the deficit ratio and thus on the scope for fiscal stabilization, but also on the extent to which fiscal policy can be used for structural purposes. But the fiscal rules are operated in many ways and adopted in various forms, with different binding of each other, according to their own fiscal situations, and political circumstances. This study shows several important factors for successful National fiscal system and continuous fiscal soundness and development.

Purpose - Along with the rise of foreign investments in the Korean stock market, there has been a variety of studies on their influence. The conflicting findings on the question of information asymmetry of foreign investors among existing literatures appear to be a result of mixture of research method problems, what information is defined as being comparable, individual business levels, or the entire stock market. This paper empirically investigates what factors contribute to foreign investments in firms in the Korean stock market. Research design, data, and Methodology - Samples are constructed by manufacturing firms listed on the stock market of Korea as well as those who settle accounts in December from 2001 to 2018. Financial institutions are excluded from the sample as their accounting procedures, governance and regulations differ. This study adopted the panel regression model to assess the sample construction including yearly and cross-sectional data. Result - This paper find that firms' R&D, dividends, size give significant positive impact to foreign investment, whereas debt gives significant negative impact to foreign investment. This relationship does not change when the samples are divided before and after the 2008 global financial crisis. Conclusion - This results support the literatures that foreign investors favor firms lowering their information asymmetry.

This paper investigates how does cash holdings have effect on investment-cash flow sensitivity in korea firms over the period 1981-2009. According to $\"{O}$.Arslan et al.(2006), I expect that financially constrained firms have more cash holdings. and financially constrained cash-rich firms are likely to have less investment-cash flow sensitivity especially in the financial crisis period. Using financial constraint classification variables(firm size, dividend, cash holdings), we divide whole sample firms into financially constrained firms and financially unconstrained firms, and then I compare investment-cash flow sensitivity in pre-financial crisis(1981-1996), financial crisis(1997-1998) and after-financial crisis(1999-2009) period. This paper's findings are as follows: First, under no financial constraint classification conditions, cash-poor firms exhibit greater investment-cash flow sensitivity than cash-rich firms do during 1981-2009 period except financial crisis period. These findings support the hypothesis that firms have more cash holdings less investment-cash flow sensitivity except in financial crisis period. In financial crisis period, cash holdings have no effect on investment-cash flow sensitivity. Second, this paper findings are somewhat different as $\"{O}$.Arslan et al.(2006)'s. Under the financial constraint classification conditions, financially unconstrained firms have more investment-cash flow sensitivity rather than constrained firms have. The reason is that both dividend and firm size are not a complete classification criteria variables. And there exists other possible determinants of investment-cash flow sensitivity. Finally, this paper find that there are common determinants of corporate cash holdings in all periods. This paper suggests that cash flow and market to book ratio are positive determinants of corporate cash holdings but short-term debt, investment and firm size are negative determinants of corporate cash holdings.

In applying Markowitz's portfolio selection model to the stock market, we developed a comprehensive investment decision-making framework including key inputs for portfolio theory (i.e., individual stocks' expected rate of return and covariance) and minimum required expected return. For estimating the key inputs of our decision-making framework, we utilized an exponentially weighted moving average (EWMA) which places more emphasis on recent data than the conventional simple moving average (SMA). We empirically analyzed the investment results of the decision-making framework with the same 15 stocks in Samsung Group Funds found in the Korean stock market between 2007 and 2011. This five-year investment horizon is marked by global financial crises including the U.S. subprime mortgage crisis, the collapse of Lehman Brothers, and the European sovereign-debt crisis. We measure portfolio performance in terms of rate of return, standard deviation of returns, and Sharpe ratio. Results are compared with the following benchmarks : 1) KOSPI, 2) Samsung Group Funds, 3) Talmudic portfolio based on the na$\ddot{i}$ve 1/N rule, and 4) Markowitz's model with SMA. We performed sensitivity analyses on all the input parameters that are necessary for designing an investment decision-making framework : smoothing constant for EWMA, minimum required expected return for the portfolio, and portfolio rebalancing period. In conclusion, appropriate use of the comprehensive investment decision-making framework based on the Markowitz's model integrated with EWMA proves to achieve outstanding performance compared to the benchmarks.

It has been more than four years since the outbreak of global financial crisis. However, the world economy continues to be challenged with new crisis such as the European debt crisis and the fiscal cliff issue of the U.S. The global economic environment remains fragile and prone to further disappointment, although the balance of risks is now less skewed to the downside than it has been in recent years. It's no wonder that maritime business will be bearish since the global business affects the maritime business directly as well as indirectly. This paper, hence, aims to predict the Baltic Dry Index representing the shipping business using the ARIMA-type models and Hodrick-Prescott filtering technique. The monthly data cover the period January 2000 through January 2013. The out-of-sample forecasting performance is measured by three summary statistics: root mean squared percent error, mean absolute percent error and mean percent error. These forecasting performances are also compared with those of the random walk model. This study shows that the ARIMA models including Intervention-ARIMA have lower rmse than random walk model. This means that it's appropriate to forecast BDI using the ARIMA models. This paper predicts that the shipping market will be more bearish in 2013 than the year 2012. These pessimistic ex-ante forecasts are supported by the Hodrick-Prescott filtering technique.

The purpose of this study is to examine the changes in financial structure of the self-employed brought on the economic crisis in Korea.. We use financial ratio analysis, such as income to expenditure ratio, liquidity ratio, debt ratio, and capital accumulation ratio to analyze financial well-being of self-employed households. This study used a 1997 and 1998 Korean Household Panel Study collected by Daewoo Economic Research Institute. The average amount of holding of each type of asset showed that the investment of self-employed households decreased in the banking industry and the stock market in 1998 compared to 1997. On the other hand, asset allocation in bond and real estate increased, which implied preference for a stable type of asset with the increase in uncertainty of the future and economic instability. Devaluation of real estate allowed households to easily obtain real estate and increase preference for asset allocation in real estate after the crisis. The changes in financial ratio for the year 1998 shows that such ratios as income to expenditure, liquidity, and capital accumulation, decreased compared to the year 1997. Among those ratios, the income to expenditure ratio showed the biggest decline because of reduced income of self employed households. The results implied that the income structure of the self-employed is unstable, thus the self-employed were likely to be greatly affected during the economic downturn. Earners have more average income and net assets than the self-employed. However, using financial ratios, it was found that self-employed households were more stable than employees. The results shows that the financial ratio analysis is better tool to estimate households financial status. Implications for financial educators, counselors, and planners are offered. The results will provide implications for policy makers to establish appropriate policies for the self-employed and help them financially survive.

Korean society is experiencing an increase in multicultural families and single households. The incidence of the MERS, epidemic in 2015, and the subsequent cases of child abuse have been major shocks to Korean society. In addition, there has been a steady increase in household debt, that is in danger of causing a serious crisis in the stability of our society and the family. The current demand for increased accountability in the democratic process is becoming an important topic. There is also an increased awareness of natural disaster preparation due to local earthquakes that have caused concern. At this point, the lifelong education in the home economics education field in Korea is in line with the changes and crises of various societies. Problems related to family life that have happened in the real life of learners stand in the place of the study with preventive character. It should provide the best alternative for family, home, and society, and help to overcome the problems of life. In order for lifelong education to respond to these social changes $vis-{\grave{a}}-vis$ Home Economics Education, it is necessary to develop: 'formation and improvement education of family relationship', 'crisis prevention and management coping ability training', 'safety education', 'learning communication and consensus processes', 'consumer culture education', 'ethics education on environment and resources', 'sustainability education', 'local education of family relationship', 'crisis prevention and management coping ability training', 'safety education', 'learning communication and consensus processes', 'consumer culture education', 'ethics education on environment and resources', 'sustainability education', 'local economic activation education', and other topics of lifelong education topics related to the field of Home Economics Education are required. Consequently, various related programs should be further developed and disseminated.

This study proposes a mathematical model that can forecast national defense expenditures. The ongoing European debt crisis weighs heavily on markets; consequently, government spending in many countries will be constrained. However, a forecasting model to predict military spending is acutely needed for South Korea because security threats still exist and the estimation of military spending at a reasonable level is closely related to economic growth. This study establishes two models: an Auto-Regressive Moving Average model (ARIMA) based on past military expenditures and Transfer Function model with the Gross Domestic Product (GDP), exchange rate and consumer price index as input time series. The proposed models use defense spending data as of 2012 to create defense expenditure forecasts up to 2025.

Now in Korea, many factors-for example, unemployment rate rise, consumer prices, corporate restructuring, etc.-are threatening family economy. Thus many households are faced with an economic crisis. In this circumstances, it is the role of households as a subsystem of family system to keep family and household economy stable for the sake of family growth and development. Economic well-being is differentiated by criterion of household economic status. But it has a large scale of spectrum: household income, asset, consumption, debt and the like. Moreover, these indices have been understood and measured differently by many researchers. In this thesis, we made efforts to distinguish subjective satisfaction from objective satisfaction, and then focus on the former. The data were collected from 399 housewives living in Pusan through questionnaires.

During the financial crisis in the late 1990s, we witnessed the large corporations failing at one moment. It is clear that the debt-dependant size augmentation and duplicate investment, and the failure in fund liquidity adjustment were the greatest causes rather than the long-term strategic advantage. Such fact, however, has led to the introduction of advanced financial techniques and security/management of fund liquidity. In order to propose a method to secure fund liquidity at the construction level, this study considers the documentational/precedent studies on project financing among fund procurement methods. And the fund liquidity status at construction level is investigated domestically/internationally to analyze the fund flow. Finally, the actual data is used to analyze progress rate and sales rate to end with the proposal of the method to secure fund liquidity in the progression of this study.
