Human capital: Migration and rural population change

Abstract: The movement of labor out of agriculture is a universal concomitant of economic modernization and growth. Traditional migration models overlook many potential interactions between migration and development. Given imperfect markets characterizing most migrant-sending areas, migration and remittances can have far-reaching impacts, both positive and negative, on incomes and production in agricultural households. Linkages through product and factor markets transmit impacts of migration from migrant-sending households to others inside and outside the rural economy. Recent theoretical and empirical studies reveal the complexity of migration determinants and impacts in rural economies, and they point to new arenas for policy intervention.

Numbers vs. Rights: Trade-Offs and Guest Worker Programs1

Abstract: This paper examines the relationship between the number and rights of low-skilled migrant workers in high-income countries. It identifies a trade-off: Countries with large numbers of low-skilled migrant workers offer them relatively few rights, while smaller numbers of migrants are typically associated with more rights. We discuss the number-vs.-rights trade-off in theory and practice as an example of competing goods, raising the question of whether numbers of migrants or rights of migrants should get higher priority. There is no easy or universal answer, but avoiding an explicit discussion of the issue – as has been done in recent guest worker debates – can obscure an important policy choice.

Emerging adulthood. A theory of development from the late teens through the twenties.

Abstract: Emerging adulthood is proposed as a new conception of development for the period from the late teens through the twenties, with a focus on ages 18-25. A theoretical background is presented. Then evidence is provided to support the idea that emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations. How emerging adulthood differs from adolescence and young adulthood is explained. Finally, a cultural context for the idea of emerging adulthood is outlined, and it is specified that emerging adulthood exists only in cultures that allow young people a prolonged period of independent role exploration during the late teens and twenties.

Social Capital: Its Origins and Applications in Modern Sociology

Abstract: This paper reviews the origins and definitions of social capital in the writings of Bourdieu, Loury, and Coleman, among other authors. It distinguishes four sources of social capital and examines their dynamics. Applications of the concept in the sociological literature emphasize its role in social control, in family support, and in benefits mediated by extrafamilial networks. I provide examples of each of these positive functions. Negative consequences of the same processes also deserve attention for a balanced picture of the forces at play. I review four such consequences and illustrate them with relevant examples. Recent writings on social capital have extended the concept from an individual asset to a feature of communities and even nations. The final sections describe this conceptual stretch and examine its limitations. I argue that, as shorthand for the positive consequences of sociability, social capital has a definite place in sociological theory. However, excessive extensions of the concept may j...

Social capital: implications for development theory, research, and policy

Abstract: In the 1990s the concept of social capital defined here as the norms and networks that enable people to act collectively enjoyed a remarkable rise to prominence across all the social science disciplines. The authors trace the evolution of social capital research as it pertains to economic development and identify four distinct approaches the research has taken : communitarian, networks, institutional, and synergy. The evidence suggests that of the four, the synergy view, with its emphasis on incorporating different levels and dimensions of social capital and its recognition of the positive and negative outcomes that social capital can generate, has the greatest empirical support and lends itself best to comprehensive and coherent policy prescriptions. The authors argue that a significant virtue of the idea of and discourse on social capital is that it helps to bridge orthodox divides among scholars, practitioners, and policymakers.
