Korean households' expenditures on the eating -out have been steadily increasing except for the foreign exchange crisis period. This paper aimed to examine the eating-out expenditures of salary and wage earners's households by educational attainment of household head. We modeled the demand function of eating-out in terms of income and price, examining the responsiveness of eating-out demand to changes in income and price using econometric methods such as regression, rolling regression and impulse response. This paper showed that coefficients of income and price tended to decrease as the income rises in the long-run. Specifically, the higher the educational attainment of household head is, the smaller the coefficients of income and price we. The impulse response analysis also indicated that while price shocks decreased the demand for eating-out, income shocks tended to increase tile demand for eating-out in all the educational attainments. Furthermore income shocks were much greater and last longer than price shocks at all educational attainments of household heads.

This paper analyzes the firms value and the business performance before and after Chinese firms got listed in the U.S. First of all, it was separated into term before U.S listed and after listed, and looked whether there was any change in the Tobin'Q. After listed, as time went on Tobin'Q decreased more. In terms of net sales growth rate, it dropped significantly after U.S IPO. Operating profits and net profits rate increased more after being listed in large corporation, but in small corporation cases, it produced an opposite effect on debt ratio and net interest cost. Interest burden continued to fall after being listed in small corporation, and it couldn't find the investment profitability, nor could it utilize ROE, ROI variable. ROE, ROI continued to fall after being listed, but current ratio and quick ratio increased significantly in small corporation. From this results, we can infer that the financial liquidity showed signs of improvement after being listed.

This paper examines how a social investment approach can be applied in a comparative analysis of childcare arrangements. We compared changes in Sweden, France, Germany, the UK, Japan and Korea during the 2000s, focusing on four dimensions of social investment: activation, gender equality, quality of care, and the degree of state's intervention in the family. We considered leave systems and the number of children enrolled in formal care and education facilities as indicators for labour market activation. For gender equality, women's position in employment is considered with respect to labour market participation rates, proportion of permanent employment, and wage-sex ratio. Quality of care concerns child-to-staff ratio and care provided with government quality control. The state's intervention was measured as social spending on families as proportions of GDP and total social spending. Our analysis provides empirical evidence that Sweden and France are pioneers in this arena and that the UK, Germany, Korea, and Japan are path-shifters in their care paradigms, albeit to varying degrees. Is the social investment approach an adequate paradigm for care? In a normative sense, this approach has potential. However, the following issues remain unaddressed: gender equality should be achieved through an expansion in good-quality jobs, fathers should be encouraged to take on childcare duties, and families should have universal access to good-quality childcare services controlled by the government.

Since the financial crisis broke out, liquidity has become the critical issue in housing construction industry. In order to secure liquidity, it is prerequisite to precisely forecast cash flow. However, construction companies have failed to come up with a systematic process to manage and forecast cash flow. Until now, companies have solely relied on the prediction of profits and losses, which is carried out as they review business feasibility. To obtain more accurate cash flow forecast model, practical pattern of payments should be taken into account. In this theory, basic model that analyzes practical housing payment collection pattern resulting from prepayments and arrears is described. This model is to complement conventional cash flow forecast scheme in the phase of business feasibility review. Analysis result on final losses in cash that occur as a result of prepayment and arrears is considered in this model. Additionally, in the estimation of construction cost in the phase of business feasibility review, real construction prices instead of official prices are applied to enhance accuracy of cash outflow forecast. The proportion of payment made by a bill and changes in payment date caused by rescheduling of a bill are also factored in to estimate cash outflow. This model would contribute to achieving accurate cash flow forecast that better reflect real situation and to enhancing efficiency in capital management by giving a clear picture with regard to the demand and supply timing of capital.

This paper explains the one of the most problematic factor in the society that leads to social inequality - increase in non-regular work. Theoretically, this expansion of non-regular work can be explained by technologies that are designed to save the labor force, especially since corporations in Korea have strategies to replace the regular workers with temporary workers, to save money. OECD also noted that Korea's income inequality is pretty high in ranking when compared with the rest of the OECD members, and says that globalization and technological innovation are the factors of this problem. To refine the argument, this study also looks at relationship between development made in sciences - which can be stated as a proxy variable to look at the advances made in technology - and expansion of temporary work force by using VAR methodology. Based on the results of this analysis in the future temporary/regular workers ratio started with decline, then turn to rise. These temporary/regular workers ratio sustained growth prediction shows that the expansion of the temporary expansion contributes to instability and social inequality in the labor market and technological change are interrelated.

Gangwon-do is one of Korea's most popular tourist destinations, with varying tourism demands and trends across its subregions. It is crucial to identify the characteristics of tourism in each area and compare the tourism patterns over time to devise policies that revitalize tourism in each local government and promote balanced development across regions. In this paper, we classify the regions in Gangwon-do based on tourism data from the last four years and analyze the tourism pattern of each region using the non-Euclidean additive model proposed by Jeon et al. (2021). The model incorporates the proportions of visitors by age groups and the proportions of navigation searches by destination types as two covariates, and the proportions of tourism expenditure types as a response variable. We estimate the model using the smooth-backfitting method and coordinate-wise bandwidth selection. The results are visualized in ternary plots, and changes in tourism patterns over time are analyzed by comparing the ratios of prediction errors to fitting errors.

This study attemped to analyze the financial stati of single households. The financial stati of single households were analyzed using the income and expense stati, balance sheet status and selected financial ratios as components. The data of 757 single household's from the 1998 Korean Household Panel Study were utilized. The major findings are summarized as follows; 1. Male single households had higher income and expense stati than those of females but lower holdings of other asset with the exception of liquid assets. Single elderly households had the highest holdings of both real assets and debt. 2. Usually single households were retained more short-term than long-term liquid assets. The debt burden ability in using net assets was the lowest of all assets. To accumulate capital those in single household were more likely to have savings than investment assets.

This study investigated the effects of the householder's age as a proxy for the family life cycle stage variable and the householder's occupation on the household financial structures. Household financial structures are analyzed by the components of two financial statements(the income and expense statement and the balance sheet statement) and selected financial ratios. The data came from the 1998 Korean Household Panel Study. It was found that the age profiles of household finances such as household income, expenditure, savings and consumption rate, financial assets, real assets and home ownership, debt and net worth usually vary according the householder's occupation. The ratios of debt repayment and the liquidity ratios also vary in part as age changes for each occupational group.
