PRODUCTIVITY AND THE DENSITY OF HUMAN CAPITAL*

ABSTRACT We estimate a model of urban productivity in which the agglomeration effect of density is enhanced by a metropolitan area's stock of human capital. Estimation accounts for potential biases due to the endogeneity of density and industrial composition effects. Using new information on output per worker for U.S. metropolitan areas along with a measure of density that accounts for the spatial distribution of population, we find that a doubling of density increases productivity by 2–4 percent. Consistent with theories of learning and knowledge spillovers in cities, we demonstrate that the elasticity of average labor productivity with respect to density increases with human capital. Metropolitan areas with a human capital stock one standard deviation below the mean realize no productivity gain, while doubling density in metropolitan areas with a human capital stock one standard deviation above the mean yields productivity benefits that are about twice the average. These patterns are particularly pronounced in industries where the exchange of information and sharing of ideas are important parts of the production process.     

‘I arranged my own marriage': arranged marriages and post-colonial feminism

This article looks at the practice of arranged marriage among women of Indian, Pakistani and Bangladeshi origin resident in Britain. It examines the conflation of arranged marriages with forced marriages and the assumption that arranged marriages are examples of cultural practices that thwart individual agency. Drawing upon original empirical data, this article will argue that in the practice of arranged marriage, some South Asian women are able to exercise agency while choosing their marriage partner. They adapt traditional arranged marriage practices to navigate their way around strict cultural expectations and to negotiate with their family members the choice of a match that is favourable for them. It provides a corrective account of arranged marriages by challenging the stereotype of the ‘oppressed third world women' and their experiences of such marriages. The article will do this by employing the idea of post-colonial feminism and by highlighting two long-standing issues in feminist debates: the idea of agency and the conception and role of power in the struggle for women's rights. It will make a case for a post-colonial approach to feminism as one way of reconciling feminism with the politics of multiculturalism.     

Rapid denudation of Higher Himalaya during late Pliestocence, evidence from OSL thermochronology

Optically Stimulated Luminescence (OSL) of quartz, with closure temperatures of 30–35°C in conjunction with Apatite Fission Track (AFT; closure temp. ～120°C) and ⁴⁰Ar-³⁹Ar (biotite closure temperature ～350°C), were used to obtain cooling ages from Higher Himalayan crystalline rocks of Western Arunachal Himalaya (WAH). Cooling age data based on OSL, AFT and Ar-Ar thermochronology provide inference on the exhumation — erosion history for three different time intervals over million to thousand year scale. Steady-state exhumation of ～0.5 mm/yr was observed during Miocene (>7.2 Ma) till Early Pleistocene (1.8 Ma). Onset of Pleistocene glacial/interglacial conditions from ～1.8 Ma formed glaciated valleys and rapid erosion with rivers incising deep valleys along their course. Erosion enables midcrustal partial melts to move beneath the weak zone in the valley and causes an erosion-induced tectonic uplift. This resulted in a rapid increase in exhumation rate. The OSL thermochronology results suggest increased erosion over ～21 ka period from Late Pleistocene (2.5 mm/yr) to Early Holocene (5.5 mm/yr) and these are to be contrasted with pre 1.8 Ma erosion rate of 0.5 mm/yr. Enhanced erosion in the later stage coincides with the periods of deglaciation during Marine Isotope Stages (MIS) 1 and 2. The results of the present study suggest that in the present setting OSL thermochronology informed on the short-term climatic effect on landscape evolution and techniques like the AFT and ⁴⁰Ar-³⁹Ar provided longer-term exhumation histories.     

Early Permian Foraminifera from Eastern Himalaya and their palaeobiogeographic significance

Foraminiferal assemblage from Permian rocks of Eastern Himalaya, India are recorded for the first time. Twenty-two genera and twenty-eight species are documented from the Garu Formation, Eastern Himalaya. The foraminiferal assemblage supports previous age determinations based on megafauna. The distinctive foraminiferal assemblage from India supports the recognition of Australian and Afghanistan-Indian provinces in the Early Permian Austral realm. An appreciable number of common species in these provinces is indicative of close geographic links.     

Becoming modern: British-Indian discourses of arranged marriages

This article looks at the various ways in which arranged marriage is practised among members of the British-Indian population. It argues against a singular definition of this practice by highlighting the diversity of routes that lead to an arranged marriage. It also makes a case for understanding arranged marriage as a discursive practice which represents the British-Indian views on matchmaking and kinship. Drawing upon original empirical research conducted in the north-east of England, the article presents a ‘spectrum of arranged marriage’ practices that was prevalent among its practitioners. It highlights that the attraction of this institution lies in the elastic nature of the traditions associated with it. Finally, it proposes that the various discourses of arranged marriage are employed by British-Indians to interpret and tailor-make this traditional practice to carve out hyphenated identities such as British-Indian and other transnational forms of belonging. They achieve this by incorporating the demands of modernity such as the notion of romantic love and a certain level of individual choice within arranged marriage practices.     

Coming of Age: Law,Sex and Childhood in Late Colonial India

This article revisits child‐marriage legislation in colonial India between 1891 and 1929 to re‐envision the ‘child’ as a subject constituted by laws governing sex, rather than as an a priori object requiring protection from patriarchal sexual norms. Focusing on the digital construction of the child in the twentieth century, this essay introduces a new angle from which to examine recent conclusions regarding child‐marriage reform in India. By drawing attention to an understudied figure, this article demonstrates the ways in which the problem of the child might transform understandings of the nation and its women; the universe of rights and the location of culture and the place of age as number in the formulation of legal subjectivities, colonial governmentality and humanitarian accounting in late colonial India.
