Decision-makings or the related policies regarding domestic grape production heavily depends upon the known market price data and official statistics periodically announced by government, at national level. However, usual adaption of the 'simple means' from these data may bring seriously biased decision-makings when the original data are biased, especially when the data are not convinced to be normal distributions to decision makers. In this regards, this study employs Monte Carlo simulation technique to overcome the limitations, based on the decision makers' subjective assumptions on the known data, and, tries to come up with flexible range of business information regarding grape-producing farm income. The approach used in this study also provides possibility that it may be useful when adapting subjective assumptions from various statistical distributions.

The objective of this paper was to evaluate economic feasibility of biodiesel production. Biodiesel is a diesel-fuel replacement produced from domestic renewable resources such as vegetable oils. This paper deals mainly with the income and cost data to analyze economic feasibility of biodiesel. The income of a rape farmer for biodiesel was 206,894won/10a, and it's similar to barley income. In addition a rape production for biodiesel have ancillary effect. Therefore we have to use direct payment for encouraging the production and use of biodiesel.

This paper analyzes the relationship between income distribution and energy consumption from a Pareto optimal approach. For this purpose, the causality relationship between electricity consumption per capita (kWh) with respect to country groups and energy consumption per capita (kg of oil equivalent) along with gross domestic product per capita was analyzed. In addition to this purpose, a Pareto analysis was conducted to determine the countries with the highest per capita national income, how much of the world total energy they consume, and whether the law of power in the energy and electricity markets exists. Finally, the impact of official development assistance provided to low-income countries by high-income countries on the low-income countries' electricity and energy consumption was analyzed. In other words, it was questioned whether pareto redistribution policies serve the purpose or not. The Engle-Granger causality approach was used in the analysis of the causality relationship between variables. Our analysis indicated that, first, the energy data of the country groups may be inadequate in revealing income inequalities. Second, the existence of Pareto law of power and global income inequality can be explained based on energy data. Finally, Pareto optimal redistribution policies to eliminate income inequality remain inadequate in practice.

The relationship between income inequality and capital account openness is empirically investigated in this study, where macroeconomic variables have opposing effects. Panel data used in the study from the KAOPEN Index and World Bank consists of 28 Asian countries and has been examined; it contains annual observations from 1970 to 2018. The data is examined using a random-effect model based on GMM estimates. Income inequality and capital account openness are positively and significantly related, according to our findings. Overall, the findings imply that increasing income gaps reduced capital investment in nations with large discrepancies. The growing economic discrepancy is being caused by the rich's increasing income share at the expense of the poor. In Asia, inward capital account openness exacerbates income inequality, while outward capital account openness exacerbates it. As a result, income inequality slows economic growth, leading to inflation, unemployment, and increased government spending in several Asian countries. Our control factors, GDP, and other secondary school enrolments, all had a statistically significant negative relationship with income inequality. Income disparity has a positive and statistically significant association with government spending, inflation, population, trade openness, and unemployment. Income disparity has a negative association with capital account openness, gross domestic product, and secondary school enrollment.

The income and price elasticities of the timber demand for the 27 years (1953~79) in Korea were analyzed by the 3 economic growth stages - in 1953~61, in 1962~71, in 1972~79-. The results obtained are as follows : 1. In 1953~79, the income and price elasticities of the total timber demand were respectively 1.87 and -0.47 ; those of the domestic timber demand were respectively 0.09 and -0.30 ; those of the foreign timber demand were respectively 2.50 and -0.11. 2. In 1953~61, the income and price elasticities of the total timber demand were respectively 2.11 and -0.86 ; those of the domestic timber demand were respectively -2.94 and -0.57 ; those of the foreign timber demand were respectively 1.20 and 0.43. 3. In 1962~71, the income and price elasticities of the total timber demand were respectively 2.89 and -0.20 ; those of the domestic timber demand were respectively 1.38 and -0.25 ; those of the foreign timber demand were respectively 3.54 and -0.42. 4. In 1972~79, the income and price elasticities of the total timber demand were respectively 1.07 and 0.17 ; those of the domestic timber demand were respectively 1.12 and 0.12 ; those of the foreign timber demand were respectively 1.22 and 0.17.

This research is to figure out how people recognize and perceive on cosmetic attributions of imported brand and domestic brand. In other words, we are trying to analyze the brand images and figure out how they are different in demographic perspective. For this research, this research has been fulfilled from September 20th 2011 to November 5th. We have surveyed women with age between 20's to 50's. With 477 data, we have analyzed by using SPSS 18.0 Version of statistic package. We have used frequency analysis, t-test and one way ANOVA (chi-square test) for data processing method. By comparing and analyzing the 16 attribute types of imported and domestic cosmetics, there were no attention difference on 7 questionaries' but there were attention difference on 9 questionnaires'. 5 questionaries' which show higher recognition on domestic brand of cosmetic than imported brand were shown. 4questionaries' which show higher recognition on imported brand of cosmetic than domestic brand were shown. By examining the different recognitions between domestic brand and imported brand of cosmetics in demographic perspective, it did not show any attentive difference on domestic brand by district residence, age, academic ability, marriage, occupation and monthly income average. But it showed attentive difference on imported cosmetic brand. It showed that people who live in capital region, with younger age and who have not been married have high rate of preference on imported cosmetic brand. It also showed that people who have higher academic ability and with higher monthly income average have high rate of preference on imported cosmetic brand. Especially, specialized job showed highest preference.

The purpose of the study is to examine the effects of wife's employment to the family expenditures. The data used in the study was 28,329 husband-wife families taken from 1994 Expenditure Survey of Urban Families. The results showed that total expenditure for employed-wife families was 1,171,651won, which is more than 1,078,788won for non-employed-wife families. After controlling other income(total family income minus wife's income), employed-wife families spent more than non-employ-wife famillies for all expenditure categories. Also, when family income and other characteristics to be constant, expenditures of employed-wife families were more on food way from home, domestic services, public transportation, personal care services, and fees, but less on food at home, utilities, health care, and communication, compared to those of non-employed-wife families. Families with high-income-employed wife spent more on clothing services, but less on education, than those with non-employed-wife families.

Based on the work of Anand et al. (2013) we measure inclusive income growth, which combines growth in gross domestic product (GDP) per capita and growth in the equity of the income distribution. Extending the work of Causa et al. (2014), we estimate a dynamic simultaneous structural equations model of GDP per capita and inclusive income on panel data for 63 countries over the 1990-2013 period. We estimate both equations in error correction form by difference GMM (generalized method of moments). Among the explanatory variables of the level and the distribution of GDP per capita we include R&D (research and development) expenditure per capita. In OECD countries we obtain a large positive effect of R&D on GDP. R&D is found to have a positive effect on the social mobility index but its impact on the income equity index at first decreases, then switches around to become slightly positive in the long run. In non- OECD countries, R&D is found to decrease inclusive income, mostly through a negative growth effect but also because of a slightly increasing income inequity effect.

Travel is a factor that stimulates the vitality of the urban and is widely used as an indicator of sustainable growth of the region. In Korea, however, no studies has been made to predict changes in traffic and calculate the accessibility of the region by comprehensively considering the socio-economic conditions of the travelers. The purpose of this study is to classify commuters according to the household income and to analyse the traffic characteristics of each class. The analysis results are aggregated into two. First, the analysis of study found different transport characteristics for different income classes. This is the result that underpins the argument of a previous study that suggested that a discriminatory approach is necessary for each income in determining the accessibility of the region. Second, this study calculated utility values differently for each income class based on the transit time and cost required between each zone. Through these measures, transport characteristics were analyzed by income class using indicators that considered transportation infrastructure, and socio-economic conditions of the travelers. This study is meaningful in that it provided the basis for calculating the accessibility that could take into account the activities of the housing consumers in establishing domestic housing policies.

The purposes of this study are as follows: 1) To estimate the amounts of differences in service expenditures resulting from the effects of mother's marital and employment status. 2) To find out the relationship of socio-economic variables to expenditures for time-saving durables and services Data were taken from the 1988-1989 Consumer Expenditure Survey. The sample consisted of 2,216 families with 334 single-mother families and 1,792 married-mother families. Tobit regres-sion analyses were used to test of variables related to expenditures for (a) food away from home. (b) clothing care (c) child care (d) domestic services and (e) total services. The results of this study were as follows; 1) The percentage difference from non-employed married-mother families was higher for employed single-mother families than for other types of families indicating the positive effect on expenditures on market substitutes of mother's marital and employment status. 2) The father's wage rate was associated only with expenditures for domestic services. A positive relationship was found between family nonlabor income and domestic services Total family income was positively associated with expenditues for all dependent variables. There was a negative relationship between expenditures for child care and age of mother squared. Mother's education was associated with expenditures in all categories. Families of nonwhite spent less on time-saving durables. food away from home, and total services and spent more on apparel services than families of white mothers. The presence of young child was positively related to total services and child care services and negatively related to food away from home.
