Optimal Growth with Public Capital and Public Services

We characterize optimal economic growth in an endogenous growth model in which production requires public capital (a stock) and public services (a flow) in addition to private capital and labor. We analyze the comparative static effects of changes in the fundamental technological and preference parameters of the model on the optimal values of several variables, such as the optimal rate of growth and the optimal allocation of resources among consumption, the provision of public services, and investment in public and private capital. We show that the general optimal path converges in finite time to the balanced growth optimal path. We relate our paper to important contributions to the existing literature by obtaining them as special cases of our model.     

Sex estimation from foot dimensions in an indigenous Indian population

Dismembered/severed human remains are frequently found in cases of mass disasters and criminal mutilation. Sex estimation from foot dimensions, therefore, has a vital role in establishing personal identity. There is a paucity of literature on this issue from various Indian populations. The "Rajbanshi" is one such indigenous population located in the state of West Bengal, India. The present study attempts to estimate sex from foot length, foot breadth, and foot index among 350 living adult Rajbanshi (175 men and 175 women) individuals (age range: 18-50 years). The study concludes that foot dimensions show significant sex differences. Both sectioning point and regression analyses can be used to estimate sex from foot dimensions. However, multiple regression models appear to have the maximum accuracy in sex differentiation. Although statistically significant sex differences are evident for foot index, its practical utility appears to be limited because of considerable overlap.     

An economised craniofacial identification system

It has been attempted to develop an economised craniofacial identification system, as a special automated version of photo/video superimposition technique, that can deal with common cases of personal identification with the aid of a skull and a nearly front view face photograph of the suspected victim.The proposed method is economic in respect of (i) cost of hardware configuration, (ii) processing time as well as (iii) manual labour involved. Over and above, it has got a capability to take care of ambiguities due to soft tissue thickness during the selection of facial features, which is a part of the procedure.In order to reconstruct a 2-D cranial image, superimposable over the facial one, the new method does not need any reconstruction of a digitised 3-D cranial image. It works simply by a suitable segment-wise processing of a 2-D cranial image with the aid of the symmetry perceiving adaptive neuronet (SPAN), that has recently been introduced in connection with nearly front view facial image recognition. The final comparison of the facial and the superimposable cranial images is as versatile as the same for facial image recognition by SPAN.A practical application of this extended version of SPAN has been demonstrated in the present paper.     

The Role of Access Mechanisms in Effective Rehabilitation of Displaced Farmers Due to Development Projects

This paper provides an access based explanation of why institutional arrangements of compensation provision for land acquisition often fail to effectively rehabilitate displaced farmers in a developing country context like India. Farmers have a right to claim compensation in case of land takings, which specifies two methods of claim: consent method and arbitration method. Literature indicates that farmers’ choice between the two methods has a significant impact on the compensation they receive. Using a binary response model on a primary dataset of 199 displaced farmers from Upper Krishna Irrigation Project, India, we analyse the determinants of this choice. We validate ‘access based’ hypotheses in choice of compensation and test whether in addition to allocated property rights, benefits actually depend on the ‘access mechanisms’ farmers have. Results suggest that the choice is governed by access to social identity and information. Therefore, farmers lacking these fail to get resettled despite the presence of a policy framework aimed at their rehabilitation.
