On the Noisy Feedback Capacity of Gaussian Broadcast Channels

It is well known that, in general, feedback may enlarge the capacity region of Gaussian broadcast channels. This has been demonstrated even when the feedback is noisy (or partial-but-perfect) and only from one of the receivers. The only case known where feedback has been shown not to enlarge the capacity region is when the channel is physically degraded (El Gamal 1978, 1981). In this paper, we show that for a class of two-user Gaussian broadcast channels (not necessarily physically degraded), passively feeding back the stronger user's signal over a link corrupted by Gaussian noise does not enlarge the capacity region if the variance of feedback noise is above a certain threshold.Comment: 5 pages, 3 figures, to appear in IEEE Information Theory Workshop 2015, Jerusale

‘One hen’ or ‘a basket of bangles’: women development and micro-credit in Tamil Nadu

Tamil Nadu in India has a glorious tradition of recognizing the importance of empowering women over several centuries. The State fares reasonably well (above the all-India level) in terms of indicators such as female literacy, girls enrollment, female life expectancy, and women’s access to basic amenities. The maternal mortality rates and total fertility rates are also lower than the national average. In terms of political participation, women are faring reasonably well. While the absolute condition of women in Tamil Nadu is better than that in most States, the position of women vis-à-vis men with respect to literacy, education, work force participation, wages, asset-ownership and political participation has not improved. It is recognized that the main obstacles to empowerment has been the low level of educational attainments as well as poverty among women. Taking into account this fact, the Government of Tamil Nadu has framed various policies, designed specific interventions and implemented many programmes to eradicate poverty and to provide education to the vulnerable sections of the society. These different Government-sponsored schemes are implemented through women’s self-help groups. The present paper discusses the experience of Tamil Nadu in women development and micro-credit.Women empowerment, micro-credit, Tamil Nadu, Mahalir Thittam

Empowering the frailty: dissecting the role of microcredit

The present paper seeks to dissect the significance of micro-credit in empowering women. It starts with a brief discussion on the role of micro-credit in poverty alleviation in general, widely acclaimed in contrast to the top-down policies. The concept of empowerment is defined from different perspectives of power, feminism and personal autonomy in family framework before taking up the agency of micro-credit for analysis. Here we identify three contrasting ‘paradigms’ with different underlying aims and understandings and different policy prescriptions and priorities in relation to both micro-finance itself and to gender policy such as the feminist empowerment paradigm, the poverty alleviation paradigm and the financial self-sustainability paradigm. Though some evaluations paint a positive picture of the impact of credit programs on women's lives in that access to savings and credit can initiate or strengthen a series of interlinked and mutually reinforcing ‘virtuous spirals’ of empowerment, we take care not to ignore the practical difficulties involved. Also considered in this respect is the role of outside agencies in the empowerment process.women empowerment, micro-credit, power, poverty alleviation, family, autonomy

Women in Development – Dissecting the Discourse

The concept of women’s development has now become an integral part of the development discourses and policy initiatives. This development has been informed by a remarkable though gradual shift in the perception about women, from the stature of victims and passive objects to that of independent agents. A significant impetus to raising such an informed platform came with the adoption of development issues within the UN system, in the background of increasing activism of development practitioners. The present paper critically traces the contours and its possible shades of this awakening that rises from the less ‘threatening’ planning for Women in Development (WID) to the more ‘confrontational’ gender planning with its aspiring goal of empowerment and emancipation. These movements have occasioned an increasing space for policy initiatives and interventions in favour of poor women in the Third World. There has been a gradual shift in orientation of these policy approaches towards women from ‘welfare’, to equity’ to anti-poverty’ to ‘efficiency’ and finally to ‘empowerment’. The policy reorientation reflects the changes in the basic economic approaches of the time, from modernization policies of accelerated growth, to basic needs strategies of growth with redistribution, to the recent so-called ‘compensatory measures’ for the neo-liberal illfare. The paper argues, inter alia, that the compensatory measures imply a substitution of the agency of civil society for that of the state in development process, the original agenda of the neo-liberalism.Women; Gender; Development; Equity; Empowerment

Raising the ‘Beatrice’s Goat’: The Indian Experience in Microcredit

Empowerment of the poor entails three basic inter-linked dimensions – generation of employment (and income), reduction of poverty, and erasing inequality. The perspective has now undergone a basic change from the collective care mechanism of a paternalistic state intervention meted out from the top to bottom to a people-centered and participation-oriented bottom up approach. With this new perspective, new practices have emerged through integrated community participation of the poor. Thus the basis of the concept of micro finance is self-mobilization and self-organization of the poor at the community level driven by an ardent desire backed by an unfaltering trust in their own inherent capacity to improve their living conditions by themselves, given an enabling environment. An active realization of such self-mobilization is found in self help groups (SHGs), formed for distributing the microcredit benefits, inspired by the success of the Bangladesh Grameen experiment. This approach has already taken strong roots across the lengths and breadths of India as an effective and viable channel to take the poor to a new domain of economic empowerment and social upliftment. Microcredit, which synergies the thrift and credit habits of the poor in a participatory and informal setting, is now widely acknowledged as a strategic tool in all poverty alleviation programmes. This paper discusses the Indian experience in microcredit.Microcredit; Indian experience; empowerment; financial inclusion
