Twenty Years of Expenditure Inequality in Indonesia, 1993–2013

In this article, we consider the recent increase in inequality in Indonesia. We make new, consistent estimates of expenditure inequality for 1993–2013, using several measures that draw on household expenditure data from the National Socioeconomic Survey (Susenas) for 1993–2013. In doing so, we note that the central statistics agency, Badan Pusat Statistik (BPS), used grouped data for its estimates of inequality until 2009 and that this underestimated inequality up to then. Thus the rise in inequality reported since 2009 actually has a longer history. We argue that Indonesia experienced divergence and convergence at the same time: the magnitude of the rise in inequality was significant (divergence), but the rise was greatest in provinces or districts with low initial levels of inequality (convergence). We consider the literature on drivers of changes in inequality and identify a set of hypotheses, with an empirical basis, which we introduce as potential Indonesian-specific drivers of rising inequality for future exploration.     

Using Personal Car Register for Measuring Economic Inequality in Countries with a Large Share of Shadow Economy: Evidence for Latvia

We suggest using information from the state register of personal cars as an alternative indicator of economic inequality in countries with a large share of shadow economy. We illustrate our approach using the Latvian pool of personal cars. Our main finding is that the extent of household economic inequality in Latvia is much larger than officially assumed. According to Eurostat, the officially published estimate of the Gini coefficient for Latvia is 0.374 for 2009, which is much higher than the Gini coefficient value reported for all the 27 EU member countries (0.304), but significantly lower than 0.48 according to our results.

The trend of the Gini coefficient of China (1978–2010)

ABSTRACT

This study proposes a new approach to analyse the effects of an overlap term on the calculation of the overall Gini coefficient and estimates China’s Gini ratios since the adoption of the economic reform and open-door policies. A decomposition of the Chinese Gini coefficient for 1978–2010 reveals that the key factor contributing to income inequalities is the income disparity between rural and urban inhabitants. We further investigate the features of this income inequality between rural and urban areas and employ statistical approaches to evaluate the effects of urbanisation and rural-to-urban average income on nationwide income inequality. The results show that accelerating the pace of urbanisation is mainly responsible for decreasing China’s income disparity. Drawing on these results, we conclude with suggestions for related policies.     

筏板基础下碎石桩改良软土地基性能的数值研究

为解决传统碎石桩加固软土地基研究中忽视碎石桩侧向膨胀的问题,在对筏板基础下碎石桩排水荷载条件下加固软土地基的性能进行评估的基础上,利用PLAXIS 3D数值模拟方法研究了桩间距、直径和桩长等参数对筏板基础长期性能的影响,同时分析了各参数对筏板基础整体沉降、弯矩和碎石桩侧胀的影响。结果表明：1）软土中碎石桩的存在显著降低了筏板基础的沉降和弯矩;2）碎石桩的侧向胀形分布取决于其位置的深度;3）筏板基础的沉降、弯矩和侧向胀形随着间距与桩径比的减小、面积置换率和碎石桩长度的增加而增加;4）采用长厚比为0.75的碎石桩加固软土,可以达到良好的加固效果。研究结果对于全面了解筏板基础下碎石桩改良软土的侧胀性状具有重要意义,对于今后类似工程加固设计具有参考借鉴价值。     

新疆旅游业投入产出分析

本文以新疆2002年和2007年投入产出表为依据,从直接消耗系数和完全消耗系数、感应度系数和影响力系数以及投入产出乘数效应这三方面对新疆旅游业进行投入产出分析后发现,新疆旅游业对新疆经济的推动作用有限,旅游业自身的发展依赖于交通运输业、批发零售业、住宿餐饮业及交通运输设备业的发展,且旅游业的发展并未带来交通运输业的显著发展。
