Are Job Networks Localized in a Developing Economy? Search Methods for Displaced Workers in Thailand

Effects of localized personal networks on the choice of search methods are studied in this paper using evidence of displaced workers by establishment closure in Thailand Labor Force Survey, 2001. For the blocks/villages level, there is less significant evidence of local interactions between job-seekers and referrals in developing labor markets. The effects of localized personal networks do not play an important role in the probability of unemployed job-seekers seeking assistance from friends and relatives. Convincing evidence from the data supports the proposition that both self-selection of individual background-like professions and access to large markets determine the choice of job search method.

Rural to Urban Migration: A District Level Analysis for India

Based on the recent census data this paper analyses the district level rural to urban migration rates (both intra-state and the inter-state) among males and females separately. Both the rates are closely associated irrespective of whether the migrants originate from the rural areas within the state or outside the state. This would suggest that women usually migrate as accompanists of the males. Though many of the relatively poor and backward states actually show large population mobility, which is primarily in search of a livelihood, the mobility of male population is also seen to be prominent in the relatively advanced states like Maharashtra and Gujarat. Rapid migration of rural females within the boundaries of the states is, however, evident across most of the regions. The social networks, which play an important role in the context of migration are prevalent among the short distance migrants and tend to lose their significance with a rise in the distance between the place of origin and destination though there are some exceptions to this phenomenon. Besides the north-south divide in the Indian context is indeed a significant phenomenon with a few exceptions of metropolitan cities. As regards the effect of factors at the place of destination, prospects for better job opportunities are a major determinant of male migration. Low castes and minority groups tend to pull migration through network effects. Among females also these effects are evident though with the inclusion of the male migration rate they become less significant. Finally the paper brings out the policy implications.

Indian IT software engineers in Japan : a preliminary analysis

In this study, the work and life of Indian IT engineers in Japan engaged in software development were examined through a questionnaire survey. Findings were further supported by comparative analyses with Chinese and Korean software engineers. While Indian IT software engineers appeared rather satisfied with their life overall in Japan, they seemed rather dissatisfied with their work conditions including such things as fringe benefits, the working-time management of the company, levels of salary and bonuses, and promotion opportunities. It was made clear that profiles and perceptions of Indian engineers and those of Chinese and Koreans in Japan were different.

Issues Affecting the Movement of Rural Labour in Myanmar: Rakhine Case Study

This paper presents issues affecting the movement of rural labour in Myanmar, by examining the background, purpose and earned income of labourers migrating to fishing villages in southern Rakhine. A broad range of socioeconomic classes, from poor to rich, farmers to fishermen, is migrating from broader areas to specific labour-intensive fishing subsectors, such as anchovy fishing. These labourers are a mixed group of people whose motives lie either in supplementing their household income or accumulating capital for further expansion of their economic activities. The concentration of migrating labourers with different objectives in this particular unstable, unskilled employment opportunity suggests an insufficiently developed domestic labour market in rural Myanmar. There is a pressing need to create stable labour-intensive industries to meet this demand.

Myanmar migrant laborers in Ranong, Thailand

Thailand is the major destination for migrants in mainland Southeast Asia, and Myanmar (Burmese) migrants account for the dominant share. This paper sheds light on the actual working conditions and the life of Myanmar migrants in Thailand, based on our intensive survey in Ranong in southern Thailand in 2009. We found a wide range of serious problems that Myanmar migrants face in everyday life: very harsh working conditions, low income, heavy indebtedness, risk of being human-trafficking victims, harassment by the police and military (especially of sex workers), high risk of illness including malaria and HIV/AIDS and limited access to affordable medical facilities, and a poor educational environment for their children.

Seasonal migration and micro-credit in the lean period : evidence from northwest Bangladesh

This paper investigates the relationship between access to micro-credit and temporary seasonal migration, an issue which is largely ignored in the standard rural-urban migration literature. Seasonal migration due to agricultural downturns is a common phenomenon in developing countries. Using primary data from a cross-sectional household survey from the northwest part of Bangladesh, this study quantifies the factors that influence such migration decisions. Among other results, we find that network effects play a significant role in influencing the migration decision, with the presence of kinsmen at the place of destination having considerable impact. Seasonal migration is a natural choice for individual suffering periodic hardship; however the strict weekly loan repayment rules of Micro-credit Institutes can have an adverse effect on this process, reducing the ability of borrowers to react to a shock. Our result suggests that poor individuals prefer the option of not accessing the micro-credit and opt for temporal seasonal migration during the lean period. The results have numerous potential policy implications, including the design of typical micro-credit schemes.

Returns to migration : the role of educational attainment in rural Tanzania

Given the migration premium previously identified in an impact evaluation approach, this paper asks the question of why migration is not more prominent, given such high premium associated with it. Using long-term household panel data drawn from rural Tanzania, Kagera for the period 1991-2004, this study aims to answer this question by exploring the contribution of education in the migration premium. By separating migrants into those that moved out of original villages but remained within Kagera and those who left the region, this study finds that, in consumption, the return on investment in education is higher at both destinations. However, whilst the higher return on education fully explains the gains associated with migration within Kagera, it only partly explains those of external migration. These findings suggest that welfare opportunities are higher at the destination and that an individual's limited investment in education plays a major role in preventing short-distance migration from becoming a significant source of raising welfare, which is not the case for long-distance migration. While education plays a role, it appears that other mechanisms may prohibit rural agents from exploiting the arbitrage opportunity when they migrate to the destination at a great distance from the source.

Migration as a rural development strategy and the migrants involved : an account of a migrants' hometown in Sichuan, China

This paper attempts to describe part of the history of Chinese rural migration to urban industrial areas. Using a case study of a township in Sichuan, the author examines a type of rural development which she defines as a "bottom-up" style strategy of regional development. Different types of social mobility are observed in the case study, and over its long history, migration in the township has offered diverse means of social mobility to the local peasants. The paper concludes by considering the diversity and limits of Chinese social mobility at this stage.

Shrinking population and the urban hierarchy

This paper examines whether population shrinkage leads to changes in urban hierarchy in terms of their relative size and function from the standpoint of the new economic geography. We find some salient patterns in which small cities in the agglomeration shadow become relatively bigger as medium industries spill over on them. This appears to be quite robust against a variation in the rate of natural change among cities. Thus, rank-size relationship and the urban hierarchy are partly disrupted as population shrinks. Regarding the welfare of the residents, a lower demand for land initially causes rent to go down, which boosts the utility. However, the illusion is short-lived because markets soon begin to shrink and suppress wages. We also find that it is better to maintain a slow pace of overall population decline in the long-term perspective. More importantly, it is crucial to sustain the relative livability of smaller cities to minimize the overall loss of utility.

Marriage as women's old age insurance : evidence from migration and land inheritance practices in rural Tanzania

In a traditional system of exogamous and patrilocal marriage prevalent in much of Sub-Saharan Africa, when she marries, a rural woman typically leaves her kin to reside with her husband living outside her natal village. Since a village that allows a widow to inherit her late husband's land can provide her with old age security, single females living outside the village are more likely to marry into the village. Using a natural experimental setting, provided by the longitudinal household panel data drawn from rural Tanzania for the period from 1991 to 2004, during which several villages that initially banned a widow's land inheritance removed this discrimination, this study provides evidence in support of this view, whereby altering a customary land inheritance rules in a village in favor of widows increased the probability of males marrying in that village. This finding suggests that providing rural women with old age protection (e.g., insurance, livelihood protection) has remarkable spatial and temporal welfare effects by influencing their decision to marry.

Relationship between young women and parents in rural Ethiopia

In rural Ethiopia, parents play an important role in the major life events of their daughters such as education and marriage. However, parents’ roles have been evolving, likely due to the rapid expansion of educational opportunities for girls and the growing need of cash income among rural households. Currently, encouraging their daughters to take up further education and jobs in the formal sector contrasts with rural Ethiopian women’s conventional life course events in the past, which are characterized by early marriage and low educational profiles. An interview analysis with parents of young women indicated that under the continuing de-agrarianization among rural households, women are expected to have their own cash income generating activities to qualify as marriage partners.

Measuring population mobility speed from space

Ad-hoc population dynamics in Krugman’s type core and periphery models adjust population share of a region, based on its real wage rate deviation from national average, at pre-specified speed of population mobility. Whereas speed of population mobility is expected to be different across countries, for geographical, cultural, technological, etc. reasons, one common speed is often applied in theoretical and simulation analysis, due to spatially patchy, and temporally infrequent, availability of sub-national regional data. This article demonstrates how, increasingly available, high definition spatio-temporal remote-sensing data, and their by-products, can be used to measure speed of population mobility in national and sub-national level.

Partition, independence, and population geography in Bengal

This study quantitatively explores the changing population geography in Bengal, with a particular focus on Partition in India in 1947 and Independence of Bangladesh in 1971. Based on decadal census data from 1901 to 2001 at the district level, this paper explores how trends in regional population growth evolved with such historical events. Following Redding and Sturm (2008), Differences-in-Differences estimation is also employed. Estimation results show that there were different shocks on both sides and from both events. In West Bengal, the change in the regional population trends occurred in 1947 and remained similar thereafter. On the other hand, in East Bengal, the population growth became statistically significant after 1971. Further robustness checks show that the impacts were not uniform with respect to the distance from the border. Overall analyses show that the emergence of the international border in Bengal had asymmetric impacts on both sides.

Purification, cDNA cloning, functional expression, and characterization of a 26-kDa endogenous mammalian carboxypeptidase inhibitor.

The recent demonstration of the occurrence in rat brain and other nonpancreatic tissues of carboxypeptidase A (CPA) gene transcripts without associated catalytic activity could be ascribed to the presence of a soluble endogenous protein inhibitor. This tissue carboxypeptidase inhibitor (TCI), detected by the inhibition of added bovine pancreatic CPA, was purified from rat brain. Peptides were obtained by partial proteolysis of purified TCI, a protein of approximately 30 kDa, and starting from their sequences, a full-length cDNA encoding a 223-amino acid protein containing three potential phosphorylation sites was cloned from a cDNA library. Its identity with TCI was shown by expression in Escherichia coli of a recombinant protein recognized by antibodies raised against native TCI and display characteristic CPA-inhibiting activity. TCI appears as a hardly reversible, non-competitive, and potent inhibitor of CPA1 and CPA2 (Ki approximately 3 nM) and mast-cell CPA (Ki = 16 nM) and inactive on various other proteases. This pattern of selectivity might be attributable to a limited homology of a 11-amino acid sequence with sequences within the activation segments of CPA and CPB known to interact with residues within their active sites. The widespread expression of TCI in a number of tissues (e.g., brain, lung, or digestive tract) and its apparently cytosolic localization point to a rather general functional role, e.g., in the control of cytosolic protein degradation.
