This paper studies the size distributions of urban agglomerations for India and China. We have estimated the scaling exponent for Zipf’s law with the Indian census data for the years of 1981–2001 and the Chinese census data for 1990 and 2000. Along with the biased linear fit estimate, the maximum likelihood estimate for the Pareto and Tsallis q-exponential distribution has been computed. For India, the scaling exponent is in the range of [1.88, 2.06] and for China, it is in the interval [1.82, 2.29]. The goodness-of-fit tests of the estimated distributions are performed using the Kolmogorov–Smirnov statistic.

We investigate into the rank-size distributions of urban agglomerations for India between 1981 to 2011. The incidence of a power law tail is prominent. A relevant question persists regarding the evolution of the power tail coefficient. We have developed a methodology to meaningfully track the power law coefficient over time, when a country experience population growth. A relevant dynamic law, Gibrat’s law, is empirically tested in this connection. We argue that these empirical findings for India are in contrast with the findings in case of China, another country with population growth but monolithic political system.

In this article, we raise sustainability issues in a targeted health initiative, namely the Rashtriya Swasthya Bima Yojana. This unique health insurance initiative targets the poor population to address the iniquity in healthcare in the Indian societal context. We analyze this initiative because it is a unique case of a public–private partnership in the development sector arena in India being used as an instrument for improving the health care system on a large scale. The initial success stories from this initiative include improved hospitalization rates for the targeted population, a reduction in their out-of-pocket health care spending, and a reasonable incentive encouraging the participation of insurance companies. The sustainability of this initiative, however, is threatened mainly by a lack of information, heterogeneity in access, institutional shortcomings and the long-run escalation of costs. While the government is employing a public–private partnership to implement this initiative, there is need to simultaneously use this model to augment the existing health infrastructure to make this initiative sustainable and effective.

Surge in sexual violence in India is a public concern in the recent times. I present the stylized facts regarding rapes in India over time and contrast them to the global data. Incidence of rape is positively associated with per capita income of a country and to female participation in the labour force. The documented empirical facts may not be representative of the reality because of many unreported incidences. Even though, we accept the empirical facts on their face value, these facts may not represent general rise in crime levels but a shift in occupational choice for women who are increasingly into non-traditional roles. I build a theoretical model where a woman has the choice to work in non-traditional sector as opposed to a traditional one. The model predicts that the gender gap in wages will reduce with technological progress but the sexual assault will register a rise. This will result in intensification in public demand for infrastructure that makes woman safe in their non-traditional role. JEL: J16, J62, O33

In this article, the relationship between two well-accepted empirical propositions regarding the distribution of population in cities, namely, Gibrat’s law and Zipf’s law, are rigorously examined using the Chinese census data. Our findings are quite in contrast with the most of the previous studies performed exclusively for developed countries. This motivates us to build a general environment to explain the morphology of urban agglomerations both in developed and developing countries. A dynamic process of job creation generates a particular distribution for the urban agglomerations and introduction of Special Economic Zones (SEZ) in this abstract environment shows that the empirical observations are in good agreement with the proposed model.

The housing asset bubble and mortgage crisis of 2007–2008 in the US market poses a challenge to understanding of market and hypotheses related to market efficiency. The contribution of our paper is bifold. First, we present a survey of the existing literature which explains the housing asset bubble. We have emphasized on agent based modeling approaches in this context. The second part of the paper frames an economic model to demonstrate the power of “irrational exuberance” hypothesis, a term coined by Robert J. Shiller. Using a felicity function based framework, this shows the power of irrational expectation in bringing about an artificial and unintended boost in demand for investment of housing asset.
