In trading relations and marketing of products of producing firms, network relations of dealers play an important role in the delivery of products and consumer satisfaction. Such dealer networks are strategically formed and the resulting network structure implies important properties. From simple random graphs to complex networks, the properties are evaluated with different parameters. This paper attempts to understand the topology of such an empirical network of dealer relations in marketing. The estimated network parameters are compared with the simulated structures of the standard network topologies of random graph, scale free, p and rewired lattice networks. The results show that the empirical dealer network is close to that of a rewired lattice structure of social networks.

Performance of an organisation depends on both tangible and intangible human capital of the workers, especially in hospital performance where work is performed by teams rather than individuals. Once a patient is treated by the physician, it is the job of the nursing staff which perform as a team to monitor the condition and recovery of the patient. The unit specific experience of nurses is critical for the critical care and speedy recovery of the patient. Yet, this form of team human capital is ignored as input in health production. This paper explores the effect of the unit specific human capital of the nursing staff measured by the average experience in specific units of a hospital on the duration of stay of patients in the unit using a unique unit level monthly panel data in a general hospital. The fixed effects panel estimates show that the average general human capital of the nurses increases the duration of stay of patients in the units, while the average unit level human capital of the nursing staff reduce their length of stay. This result implies that experienced nurses are extra cautious to ensure full recovery of patients, and the continuous unit level care by the specific nursing team reduces the post-treatment complications and ensures their better health condition. The intangible team specific human capital in specific units contributes to organisational performance.- Occupational Segregation and Earnings Differentials by Sex: Evidence from India

Female labour is on average, rewarded less than male labour in any labour market. The important sources of male-female earnings differences are the differences in occupational distribution and unequal pay for equal work. Most studies on the estimation of wage differentials concentrate either on occupational segregations or on the issue unequal treatment. This paper refines and synthesizes these two approaches, using a multinomial logit analysis and the econometric decomposition technique. Earnings are estimated as a function of productivity measures for each sexes, with sample selectivity correction. The gross earnings differences between sexes is then decomposed into a part that can be attributed to differences in human capital endowments and a part due to unexplained factors called discrimination, using a nationwide sample af science graduates in India. The findings suggest that discrimination accounts for almost two-thirds of gross earnings difference, with Wage Discrimination (WD) being considerably more pronounced than Job Discrimination (JD). Further, selectivity bias is found to be more important for a number of occupational categories.- Intrafamily Relations, Migration and Remittances

The ruling explanation for rural-urban migration in terms of expected intersectoral wage differentials grossly ignored the institutional importance of the family in migration decision making and remittances determination. Moreover, the decision making unit is an individual, the migrant, and the decision is independent. This paper attempts to develop a formal model of interdependent decision making within the context of the family with regard to migration and remittances. The migration process is viewed as a deliberate strategy designed by the family for maximizing its total welfare. The interrelationships between the migrant and the rest of the family are modelled as a self-enforcing co-operative game and the remittances are an a priori requirement for the distribution of gains in an implicit co-insurance system. The migration decision and the remittances are determined by the bargaining strength of the migrant and the rest of the family, who act to promote their own self-Interest. This new approach opens up new research interests.- Economic Utility and Demand for Children - Reply

Professor K.S. Srikantan has four major observations about my paper (this Journal, 1988): (i) the theoretical framework used is not accepted in the literature, (ii) the theoretical model is weak in the Indian context, (iii) in the empirical analysis certain variables are misinterpreted, and (iv) the conclusion of the paper is unacceptable. I will start with the importance of the theoretical framework.- Risk, Consumption Smoothing and the Family: Portfolio Management of Children and Assets in Rural Families

This paper analyses the kinds of risk faced by the family in a rural setting, sources of risk mitigation and the resulting derived demand for children by applying the principles of safety first and the portfolio choice theory. When incomes are uncertain, family designs a pbrtfolio of assets to smooth the consumption streams. Two principal forms of risk mitigation are the number of children and asset accumulation, which are risky investment. The family's problem is to avoid the disaster occuring. It is shown that,when parents are motivated to maximize the expected returns from these risky investments subject to the safety margin, the 'output' of children will be higher. When children are the only form of security or even if alternative forms of investment in physical and financial assets are available, the parents risk mitigation strategy leads to a demand for more number of children. Higher the demand for returns from investments, higher will be the demand for assets. Some supporting evidence for the conclusion have been derived from the available few studies in the Indian context.- Does Conditional Aid Promote Performance?

The GAVI Alliance (Global Alliance for Vaccines and Immunisation) is an aid programme that supplies large quantities of free and highly subsidised vaccines to developing countries on an income eligibility criterion since 2001 to improve the vaccination coverage rates. This paper estimates the impact of six different GAVI funded vaccines (DPT, Hep B, Hib, Rota, Pneumo and Measles) on the immunisation rates in developing countries using parametric and non-parametric econometric methods for the years 2005 and 2013. The regression discontinuity design estimates for the older and cheaper vaccines show a statistically significant impact on vaccination rates in 2005, whereas by 2013, the coverage rates of these vaccines show no significant impact. For the newer and more expensive vaccines, the empirical results show significant impact estimates in 2013. The GAVI Alliance aid programme has consciously increased the immunisation rates among children in almost all the developing countries.References

This paper examines the validity of the Easterlin paradox - despite vast differences in income levels, happiness level across countries is pretty much close, the rise in average life satisfaction level is not systematically associated with growth in average income in any country, and nil long-run incomehappiness relationship - in India. Replicating the cross-country analysis, the income-subjective well-being relationship is analysed within-states, between states and across states over 24 years from 1990-2014 using five waves of World Values Survey data. Applying the panel fixed effects ordered probit regression method, individual and average life satisfaction and happiness levels are estimated with NSDP per capita of each state and groups of states. The long-run income-subjective well-being relationship is analysed with changes in average subjective well-being and per capita NSDP. The estimated results reveal that there is considerable variation in subjective well-being levels within, between states and across states over time in India. While life satisfaction levels declined in most states, happiness levels slightly increased in some states. The well-being gain from income growth in low-income states is comparatively better than that of developed states. In the long-run, the change in subjective well-being levels is not commensurate with the change in NSDP per capita. The empirical results of this paper on the income-subjective well-being relationship in Indian states validate the Easterlin Paradox in India. Economic growth in the states of India have not improved the human lot, in fact, it leaves people not satisfied and less happy with their life.Keywords
