Club convergence and drivers of digitalization across Indian states

Disparity in the level of digitalization is a crucial driver of economic inequality in an economy. Although a pocket of its population is still bereft of the benefits of digitalization, India currently has the second highest number of internet subscribers in the world despite the nation's late adoption of digital technology. An accurate assessment of the current state of digitalization in the country is required for devising effective initiatives towards building a Digital India and bridging the nation's internal digital divide. Considering 17 major Indian states and 21 variables for 10 years, we constructed a composite index of digitalization with the help of Principal Component Method (PCM). This paper identifies factors responsible for the digitalization divide across states. In the second part of the analysis, the study confirms, with the help of club convergence test, the absence of overall convergence towards digitalization and the existence of the non-convergent group. This paper also shows that the non-convergent group of states are at the bottom of the ranking table which indicates the need for greater attention to initiatives to bridge the digital divide.

关于基尼系数若干问题的再研究--与部分学者商榷

基尼系数是测量收入不平等的一个重要指标,近年来有很多学者对此进行了深入研究,本文主要对有关学者的研究内容进行商榷与补充。首先,实际计算基尼系数应首选离散公式,并且根据具体的抽样方法选择无偏或有效的估计公式;其次,本文论证了对数正态分布下基尼系数G与标准差d的关系式：G=2Ф（σ/√2）-1;再次,针对基尼系数存在的不足,改进基尼系数成为一些学者的研究重点,本文发现一些改进并没有解决基尼系数与洛伦茨曲线的非一一对应问题,并且可操作性较差,通过介绍S基尼系数和E基尼系数,本文说明了基尼系数改进的总体思路;最后,针对学者提出的“部分分布决定性定理（PD定理）”,本文论证了其推理过程中存在的问题,说明该定理是错误的。     

CEV模型的单位根检验研究

CEV模型（Constant Elasticity of Variance Model）作为常用的利率模型,在实证分析中得到了广泛运用,但是其单位根检验一直被忽略或者被默认可以使用迪基一富勒检验。本文首次运用Box—Cox变换的技巧,针对CEV模型的单位根检验问题,找到了合适的统计量并且证明其渐进分布存在,然后通过蒙特卡罗方法求出了该统计量的分布表。得到了在大样本的情形下可以沿用迪基一富勒检验,但在小样本的情形下与迪基一富勒检验有所偏差的结论。

Decomposing productivity patterns in a conditional convergence framework

In this study we examine regional data on per worker GDP, disaggregated at sectoral level, by focusing our interest on the role of differences in the sectoral composition of activities, and in productivity gaps that are uniform across sectors, in explaining the catching-up process, which is realized through physical and human capital as well as technological knowledge accumulation. Our objective is to investigate how much of the interregional inequality in aggregate productivity per worker is imputable to each component. A methodology for identifying and analyzing sources of inequality from a decomposed perspective is developed in the growth framework by combining a shift-share based technique and a SUR model specification for the conditional-convergence analysis. The proposed approach is employed to analyze aggregate interregional inequality of per worker productivity levels in Italy over the period 1970–2000. With respect to the existing empirical results, our approach provides a more comprehensive and detailed examination of the contribution of each identified component in explaining the regional productivity gaps in Italy. It is argued that region-specific productivity differentials, uniform across sectors, explain a quite large share of differences in productivity per worker. However, sectoral composition plays a non negligible role, although decreasing since the end of 1980s, and very different productivity patterns emerge within geographical areas.
