The degree of inequality present in the distribution of income may be measured with a gini coefficient. If the distribution is found to empirically fit a particular distribution function, then the gini coefficient may be derived from the mean value of income and the variation from the mean. For the purpose of this study, the Beta II distribution was used as the function which most closely approximates the actual distribution of income. The Beta II function provides the skewness which is normally found in an income distribution as well as fulfilling other required characteristics. The degree of inequality was approximated for the distribution of income from all sources and from ten separate components of income sources in constant (1973) dollars. Next, permanent income from all sources and from the ten component sources was estimated based upon actual income using the double exponential smoothing forecasting technique. The estimations of permanent income, which can be thought of as expected income, were used to derive measures of permanent income inequality. The degree of actual income inequality and the degree of permanent income inequality, both being represented by the hypothetical gini coefficient , were compared and tested for statistical differences. For the entire period …

This study is an analysis of the relationship between domestic savings and three economic indicators in the Republic of Korea during the 1950s through 1980s. While domestic saving is affected by many economic phenomena, the analysis is confined to national income, exports, and inflation. The study is divided into five chapters. These are entitled (1) Introduction, (2) Domestic Savings, (3) Income and Domestic Savings, (4) Exports and Domestic Savings, (5) Inflation and Domestic Savings. In chapter I, Korea and the Korean economy are introduced, and the scope of the study is stated. Chapter II reviews the related realm of domestic savings: definition, kinds, and determinants of domestic savings. Chapter III presents the relationship between different incomes and domestic savings, and shows non-labor income contributes more powerfully to the formation of domestic savings than labor income. Chapter IV contains effects of exports, and hypothesis testing. The effect of exports suggests that export expansion affects domestic savings positively via an increase in gross national product. Chapter V deals with the correlation between inflation and domestic savings, and its testing. The correlation between inflation and domestic savings is not generally clear except for some specific cases.
