The Firm's Management of Social Interactions

Consumer choice is influenced in a direct and meaningful way by the actions taken by others. These “actions” range from face-to-face recommendations from a friend to the passive observation of what a stranger is wearing. We refer to the set of such contexts as “social interactions” (SI). We believe that at least some of the SI effects are partially within the firm's control and that this represents an exciting research opportunity. We present an agenda that identifies a list of unanswered questions of potential interest to both researchers and managers. In order to appreciate the firm's choices with respect to its management of SI, it is important to first evaluate where we are in terms of understanding the phenomena themselves. We highlight five questions in this regard: (1) What are the antecedents of word of mouth (WOM)? (2) How does the transmission of positive WOM differ from that of negative WOM? (3) How does online WOM differ from offline WOM? (4) What is the impact of WOM? (5) How can we measure WOM? Finally, we identify and discuss four principal, non-mutually exclusive, roles that the firm might play: (1) observer, (2) moderator, (3) mediator, and (4) participant.

It is where you are that matters: the spatial determinants of rural poverty in India

The spatial patterns of poverty in India are of considerable importance in themselves and for development theory and practice. This article examines the determinants of rural poverty in India using spatial econometric methods. It finds that while agricultural growth is the key determinant of rural poverty declines, there is significant spatial dependence in the growth rates of agricultural output. Irrigation is the primary driver of agricultural growth, and spatial variations in irrigation development seem to be associated with agro‐ecological conditions which may be vastly different within Indian states, parts of which may be similar to those prevailing in geographically contiguous states. Poverty reduction strategies need to be designed in the light of spatial factors and using spatial methods.     

The World Social Forum as an emergent learning process

One of the most prominent manifestations of world civil politics today—and arguably, in history—is the World Social Forum, set up in 2000-2001, which held its first world meeting in Porto Alegre, Brazil, in January 2001. Beginning with the emphasis on opposition to neo-liberal globalisation, the ferment generated by the Forum soon gave rise to its evocative slogan, ‘Another World Is Possible!’ and the emphasis moved from opposition to developing specific alternative proposals for a world level political and economic system. In the last few years, the WSF has evolved into a permanent, horizontal open public space, a commons, which provides an opportunity to diverse organisations and individuals from all over the world to meet and dialogue across boundaries and to interact and exchange information in multifarious ways to work towards making another world possible. This paper examines the dynamics of the WSF process and argues why perhaps it is one of the most significant developments of the last century, which is giving rise to another, more open culture of politics and is forging a great piece of public ‘architecture’ in our times. The WSF is not only calling for another world, in a sense it contains the other world, or plural other worlds!

Testing of the rational expectations and structural neutrality hypotheses

In this paper we examine the tests of the new classical rational expectations and structural neutrality hypotheses undertaken by Leiderman (1980) using a model of money growth and unemployment for the United States developed by Barro (1977). Employing the data used in the studies by Barro and Leiderman we are able to construct an alternative model of money growth and unemployment against which the Barro-Leiderman model is rejected along with the joint hypothesis of rational expectations and structural neutrality.     

Money for nothing: The dire straits of medical practice in Delhi,India

The quality of medical care received by patients varies for two reasons: differences in doctors' competence or differences in doctors' practice. Using medical vignettes, we evaluated competence for a sample of doctors in Delhi. One month later, we observed the same doctors in their practice. We find three patterns in the data. First, doctors do less than what they know they should do. Second, the more competent the doctor, the greater the effort exerted. Third, competence and practice diverge in different ways in the public and private sectors. Urban India pays a lot of “Money for Nothing”: in the private sector there is a lot of expenditure on unnecessary drugs. In the public sector, education subsidies and salary payments translate into little (and in small clinics, very little) effort and care. Provider training has a small impact on the actual quality of advice; under the circumstances, awareness campaigns to create a more informed clientele may be the best option.
