The welfare of a country depends on its economic development. In order to have the impact it, we should possibility quantitatively assess situation at desired point in time. Economic development, as multifaceted and complex phenomenon, is reflected two dimensions – intensity uniformity. These mentioned above can be viewed partial indicators dynamics. Two main approaches measuring development un...

Adherence to the schedule is of prime importance in public transport. This paper presents a specific application Gini coefficient, well known indicator economics, for headway adherence assessment. The shows that Lorenz curve, which usually used define mathematically good users' waiting time when it based on bus schedule. When computed basis ratio observed schedule, powerful visual tool can be b...

This paper proposes and proves the important equivalence between the Gini index and the area under the Kolmogorov-Smirnov (KS) distribution curve. The proof’s rationale is similar to that used in the proof of equivalence between AUC_ROC and AUC_KS. But different from that, this one uses a transformation that preserves the 1-to-1 correspondence between the ideal classifier on the KS and Lorenz c...

This paper introduced a new life time data analysis distribution name three parameters quasi gamma discussed about its some properties including moment generating function, rth origin and mean, mean deviations, reliability measurements, Bonferroni Lorenz curve, Order statistics, Renyi entropy, also maximum likelihood method real-life applications.

We decompose the Lorenz curve and its associated concentration curve by population subgroups. To illustrate these decompositions, we examine changes in earnings inequality among West Germans, East Germans, and foreign guest workers during the recent German unification. We show that East German earnings have become less concentrated in the lower deciles of the overall German earnings distributio...

One income distribution is preferable to another under any increasing and Schur-concave (S-concave) social welfare function if and only if the generalized Lorenz (GL) curve of the first distribution lies above that of the second (GL dominance). This paper (i) derives the asymptotic distribution of a vector of sample GL curve ordinates, interpreting it as a method-of-moments estimator, and (ii) ...

This paper presents necessary and sufficient conditions for unambiguous changes in wage inequality in a dual economy, based on analysis of the entire Lorenz curve. These conditions are then used to analyze the distributional consequences of various types of economic growth. In particular, it is shown that capital accumulation or technical progress in agriculture is likely to reduce wage inequal...

ABSTRACT The aim of this paper is to establish an ordering related to the inequality for the recently introduced Zenga distribution. In addition to the well-known order based on the Lorenz curve, the order based on I(p) curve is considered. Since the Zenga distribution seems to be suitable to model wealth, financial, actuarial and especially, income distributions, these findings are fundamental...
