The price dynamics of common trading strategies

A deterministic trading strategy can be regarded as a signal processing element that uses external information and past prices as inputs and incorporates them into future prices. This paper uses a market maker based method of price formation to study the price dynamics induced by several commonly used financial trading strategies, showing how they amplify noise, induce structure in prices, and cause phenomena such as excess and clustered volatility.Comment: 29 pages, 12 figure

Family Planning as an Investment in Development: Evaluation of a Program's Consequences in Matlab, Bangladesh

The paper analyzes 141 villages in Matlab, Bangladesh from 1974 to 1996, in which half the villages received from 1977 to 1996 a door-to-door outreach family planning and maternal-child health program. Village and individual data confirm a decline in fertility of about 15 percent in the program villages compared with the control villages by 1982, as others have noted, which persists until 1996. The consequences of the program on a series of long run family welfare outcomes are then estimated in addition to fertility: women’s health, earnings and household assets, use of preventive health inputs, and finally the inter-generational effects on the health and schooling of the woman’s children. Within two decades many of these indicators of the welfare of women and their children improve significantly in conjunction with the program-induced decline in fertility and child mortality. This suggests social returns to this reproductive health program in rural South Asia have many facets beyond fertility reduction, which do not appear to dissipate over two decades.Fertility, Family Planning, Gender and Development, Program Evaluation, Bangladesh

Female Household-Headship in Rural Bangladesh: Incidence, Determinants and Impact on Children's Schooling Shareen Joshi

This paper uses data from Matlab, Bangladesh to examine the characteristics of female-headed households and estimate the impact of female-headship on children's schooling. Female householdheads in Matlab fall into two broad groups: widows and married women, most of whom are wives of migrants. These women differ from each other not only in their current socio-economic circumstances, but also in their backgrounds and circumstances prior to getting married. To identify the effects of female-headship on children's outcomes, I use a two-stage least squares strategy that controls for the possible endogeneity of both types of female-headship. Results indicate that children residing in households headed by married women have stronger schooling attainments than children in other households, while children of widows are more likely to work outside the home. The hypothesis of exogeneity of female-headship is rejected in most cases.Female-headed Households, Widowhood, Migration, Schooling

The Economics of Consanguinity

The institution of consanguineous marriage - a marriage contracted between close biological relatives - has been a basic building block of many societies in different parts of the world. This paper argues that the practice of consanguinity is closely related to the practice of dowry, and that both arise in response to an agency problem between the families of a bride and a groom. When marriage contracts are incomplete, dowries transfer control rights to the party with the highest incentives to invest in a marriage. When these transactions are costly however, consanguinity can be a more appropriate response since it directly reduces the agency cost. Our model predicts that dowry transfers are less likely to be observed in consanguineous unions, and that close-kin marriages are more prevalent at both extremes of the wealth distribution. An empirical analysis using data from Bangladesh delivers results consistent with the predictions of the model, lending strong support to our theory

The paper's model predicts that dowry transfers are less likely to be observed in consanguineous unions. It also emphasizes the effect of credit constraints on the relative prevalence of dowry payment and consanguinity.

Missing women and India's religious demography

The authors use recent data from the 2006 National Family Health Survey of India to explore the relationship between religion and demographic behavior. They find that fertility and mortality vary not only between religious groups, but also across caste groups. These groups also differ with respect to socio-economic status. The central finding of this paper is that despite their socio-economic disadvantages, Muslims have higher fertility than their Hindu counterparts and also exhibit lower levels of infant mortality (particularly female infant mortality). This effect is robust to the inclusion of controls for non-religious factors such as socio-economic status and area of residence. This result has important policy implications because it suggests that India's problem of"missing women"may be concentrated in particular groups. The authors conclude that religion and caste play a key role in determining the demographic characteristics of India.Population Policies,Gender and Law,Gender and Health,Adolescent Health,Population&Development

The Challenges of Institutionalizing Community-Level Social Accountability Mechanisms for Health and Nutrition: a Qualitative Study in Odisha, India

Background: India has been at the forefront of innovations around social accountability mechanisms in improving the delivery of public services, including health and nutrition. Yet little is known about how such initiatives are faring now that they are incorporated formally into government programmes and implemented at scale. This brings greater impetus to understand their effectiveness. This formative qualitative study focuses on how such mechanisms have sought to strengthen community-level nutrition and health services (the Integrated Child Development Services and the National Rural Health Mission) in the state of Odisha. It fills a gap in the literature on considering how such initiatives are running when institutionalised at scale. The primary research questions were ‘what kinds of community level mechanisms are functioning in randomly selected villages in 3 districts of state of Odisha' and 'how are they perceived to function by their members and frontline workers’
