Gini coefficient is among the most popular and widely used measures of income inequality in economic studies, with various extensions and applications in finance and other related areas. This paper studies confidence intervals on the Gini coefficient for simple random samples, using normal approximation, bootstrap percentile, bootstrap-t and the empirical likelihood method. Through both theory ...

background: the purpose of the present study was to evaluate the inequality of geographical distribution of non-cardiac intensive care beds in iran using the gini coefficient. methods: the population information of iran's provinces in 2006 was obtained from the statistical center of iran and the number of non-cardiac intensive care beds (including icu, posticu and nicu beds) in all provinces wa...

this paper reviews the relationship between inflation rate and minimum wage in iran’s economy over the 1969-2005. according to the economic literature, there is a narrow relationship between inflation rate and minimum wage. some economists believe in increased inflation due to minimum wage. the other group of economists considers the increased inflation as a cause for increasing minimum wage. t...

The analysis that follows tests the regression model of Income Inequality by examining the relation among Gini coefficient, GDP growth rate, saving rate and so on within the same country. The purpose of this study is to test out the relation between income inequality and economic growth rate, and the result suggests that income inequality has a negative impact on economic growth rate in the cas...

We present a gauge-invariant formalism to study the evolution of the curvature and entropy perturbations in the case in which spatial and time variations of the inflaton decay rate into ordinary matter are present. During the reheating stage after inflation curvature perturbations can vary with time on super-horizon scales sourced by a a gauge-invariant inflaton decay rate perturbation. We show...

developing countries, including iran, have a high degree of volatility of macroeconomic variables. fluctuations inex change rate, bank interest rate and inflation rate can create insecure environment for in vestorsin iran. hence, this study examined the impact of macroeconomic variables on the tobin’s q index for the sugar companies of tehran stock exchange (tse) during the period between1380-1...

One of the main issues in international finance is the ratio of exchange rate pass through to consumer prices. The main objective of this study is to examine the exchange rate fluctuations and its asymmetric effect on consumer prices in Iran’s economy. In the present study, the effects of positive and negative impacts of the exchange rate on inflation rate and other macroeconomic variables of I...
