In a two-type Stiglitz (1982) model of optimal non-linear taxation it is shown that when the utility function relating to consumption is logaritmic the shadow price of the incentive constraint relating to the optimal tax problem exactly equals the Gini coefficient of the secondbest optimal...

In modern society the income distribution is one of the major problems. Usually, it is considered that a severe polarisation in matter of income per capita could have a major negative impact on the general process of economic development. This study is focussing on estimating dynamics of some...

The Kingdom of Lesotho’s Poverty Reduction Strategy Paper reports that consistent implementation of sound macroeconomic policies is critical to the attainment of poverty reduction objectives. At the central level, the authorities established sector working groups to facilitate the...

The paper examines empirically the question of whether more unequal societies spend more on income redistribution than their more egalitarian counterparts. Theoretical arguments on this issue are inconclusive. The political economy literature suggests that redistributive spending is higher in...

The hypothesis that income distribution follows an inverted-U pattern with respect to economic growth has been tested against US time-series data by several authors, and rejected. We reconsider this issue, paying special attention to data non-stationarity, and the use of 'unbalanced' Seemingly...

Our paper suggests, on one hand, a theoretical debate on the justification for state intervention to correct inequalities between members of society (especially on income and wealth) and on the instruments at its disposal to achieve this and their effectiveness in objective. Secondly, our...

The present study investigates the trends in inequality, welfare, and growth based on per capita household income/consumption in Pakistan, both its rural and urban areas, from 1963-64 to 2004-05. It employs Gini coefficient to measure inequalities and the Sen welfare index to estimate welfare....

In the paper the income distribution in the closed economic system is modeled. It has been shown the obtained equilibrium function for the income distribution in the society fits well the statistical data. It is also shown the Gini coef-ficient approaches its theoretical value 0.5 in the absence...
