Waste pickers and collectors in Delhi: Poverty and environment in an urban informal sector

Waste pickers and collectors constitute the bottom layer of waste recycling in the metropolis of Delhi. Pickers collect waste just by picking them up from public places such as garbage dumps and streets, whereas collectors purchase waste from waste producers such as households and shops for sale to higher-level waste traders. Most pickers have incomes below the poverty line set by the Planning Commission of India, whereas the majority of collectors earn marginally higher than the poverty-line income. The poverty of pickers is not transitory, but chronic as they have no connection to enter the community of collectors and higher-level waste traders within which the community mechanism works effectively to reduce risk and transaction costs. Despite their low economic and social status, pickers and collectors are making important contributions to society. It is found that pickers and collectors are adding more value than their own income to waste producers' income and to the saving of the city government's expenditure for disposing waste. Increased public support not only for social services, but also production services and infrastructure can be justified not only for the purposes of reducing poverty but also for furthering their positive contribution to society.     

Social Capital,Human Capital and the Community Mechanism: Toward a Conceptual Framework for Economists

For facilitating the development of a consensus on the concept of social capital among economists, this paper proposes its operational definition in a way consistent with the definitions of physical and human capital and discusses the relevance on the use of the metaphor of capital for social capital. Further, the unique characteristics in the production and accumulation of social capital in comparison with physical and human capital are identified in relation with the community which is considered the central mechanism to produce social capital. The merits and drawbacks of the community relative to the market and the state are examined with the aim of identifying the conditions under which social capital can be supplied efficiently in the direction of promoting economic progress.     

Toward a theory of induced institutional innovation

In this paper we elaborate a theory of institutional innovation in which changes in the demand for institutional innovation are induced by changes in relative resource endowments and by technical change. We illustrate, from agricultural history, how changes in resource endowments and technical change have induced changes in private property rights and in the development of non‐market institutions. We also consider the impact of advances in social science knowledge and of cultural endowments on the supply of institutional change. In a final section we present the elements of a model of institutional innovation that maps the relationships among resource endowments, cultural endowments, technology, and institutions.     

Phases of Irrigation Development in Asian Tropics: A Case Study of the Philippines and Sri Lanka

Using data for the Philippines and Sri Lanka during the last five decades, we examine three phases of agricultural development experienced by the rice sector in insular countries in tropical monsoon Asia; the first was based on land opening, the second on new irrigation construction and the third on increasing the efficiency of the existing irrigated land base. We show that these sequential shifts were induced by changes in the relative profitability of the three major means of land development for increasing food production. Rehabilitation, water management improvement and better maintenance, which are important means of irrigation development in the latest phase, are under-invested, despite their high rates of return.     

Population and households dynamics: A mountainous district in northern Japan in the Shûmon Aratame Chô of Aizu, 1750–1850

The authors examine population trends, demographic characteristics, and the family reproduction system in a highland area of Japan. Aizu district is located in northeastern Japan and has both a mountainous area and a narrow plain. The study is based on Shûmon Aratame Chô (SAC), population registers of four villages between 1750 and 1850 and focuses on the mountainous sector. Demographically, this area stagnated because of its isolation and remoteness. There were few migrations in or out. The peasants married early but bore few children. The authors show how demographic patterns are interrelated with family and household patterns. The most frequent family type was the stem family household, traditionally considered as characteristic of Japan, where the ie (house) was usually transmitted to a single heir. Family transmissions of the rural estate are observed in detail. A household cycle took about 30–35 years to complete. Major differences were seen among social classes, but, overall, Aizu families possessed ideals of ie and were incorporated into ie systems, particularly in the upper classes.     

全球化视角下农村与城市发展关系的新模式

全球化本身并不会导致或防止人口和生产向城市集中。目前发展中国家存在的过度城市化问题多源于其特定的经济发展战略。在自由开放的国际、国内贸易条件下 ,如果政府能够对小型的农户、制造商和贸易商基于农村的生产经营活动给以充分的支持 ,扭转农村和城市之间正在扩大的差距是可能的
