The state's effective response to the distress of workers during the lockdown emanates from its overall disaster preparedness and resilience achieved from confronting with two consecutive state-wide natural disasters and a public health emergency in the immediate past.

However, policy responses remained restricted to relief, for what was conceived of as a temporary problem precipitated by the lockdown. The migrant workers crisis has been treated solely as an interstate mobility issue, while the lack of wage and employment security or hazardous work conditions, which are commonplace in urban labour markets, does not feature as part of the problem description. This is evident in the attack on workers' rights by state and central governments, through a labour reforms agenda under the garb of economic revival, even at the peak of the migrants' crisis. The article uses pre- and post-Covid evidence on labour rights violations facing migrant workers in three modern, urban work sectors-construction, hotels and manufacturing-spanning the high in-migration cities of Ahmedabad and Surat in Gujarat. It juxtaposes the exploitation of migrant workers with gaps in the country's labour governance architecture, to highlight that suspension of migrant workers' rights is the central feature of urban economic growth, maintained through extra-legal and informal processes in its labour markets. It addresses core tensions and deadlocks in the labour reforms process, to move towards a labour governance architecture that is able to respond to an intersection of challenges presented by informality, mobility and social marginalisation experienced by rural-urban migrants, for enabling inclusive and equitable urban growth.</p>","PeriodicalId":34915,"journal":{"name":"Indian Journal of Labour Economics","volume":"63 4","pages":"999-1019"},"PeriodicalIF":1.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41027-020-00288-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38655848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study makes an attempt to study both inflow and outflow from the region and covers both internal and international migration. In this study, the Northeast India consists of the seven states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura. Each state of the region shares an international boundary. The paper uses data from Census 2011 and has tried to study the magnitude of inflows to the region as well as the outflows from the region at the state level and also the reasons for migration. The state of Manipur is unique in the entire Northeast as outflow is three times higher than the inflow in the state. Assam is losing population due to internal migration to other states of India but compensated by international migration. The state of Assam presents a balanced ratio of inflow and outflow as stands in 2011 contrary to the popular perception that the state is gaining population inundated by immigration. The rest of the states of Northeast are gaining population predominantly due to internal migration, whereas Tripura gained population more from international compared to internal migration. The paper throws light on the combined impact of internal and international migration in the Northeast region which is generally lacking in migration studies on Northeast relevant for economic policy and political decision making.

The study finds that there is neither quantitative nor qualitative improvement in women's employment over time on account of structural changes in the economy. There is no 'U' curve of female labour supply in response to GDP growth and expansion of female literacy, implying that economic growth has not generated adequate jobs for women. It also signifies that women's entry or exit of labour market is influenced by non-economic factors also. There is no major occupational diversification in women's employment despite structural shift of the economy from primary to tertiary sector. Agriculture is still the leading sector in women's employment. The study further reveals that the quality of women's labour is poor. Overcrowding of workforce in agriculture largely as wage labourers, lower earnings, poor literacy levels, large-scale informal employment and most self-employment in the form of unpaid work are indications of women's disadvantaged position in the labour market.</p>","PeriodicalId":34915,"journal":{"name":"Indian Journal of Labour Economics","volume":"63 3","pages":"689-717"},"PeriodicalIF":1.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41027-020-00245-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38479862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, circular migration remains poorly captured as circular migrants move back and forth between source and destination regions. Based on survey data from rural Bihar, an important source region of migration in India, this paper finds that a vast majority of migrants work and live in precarity in predominantly urban and prosperous destinations across India. However, those at the lowest rungs of the social and economic ladder in source regions-the scheduled castes and scheduled tribes, other backward classes I and the labouring class-are the worst off at destination; they are part of the most precarious shorter-term migration streams, earn the lowest incomes, have the poorest conditions of work, and live in the harshest circumstances. The paper shows that social and economic hierarchies, and in turn, precarity in source region is reproduced at destination, and, thus, there is little evidence that spatial mobility is associated with social mobility. Focusing on migrants' location, work, employment, income, housing, and access to basic services at destination, the paper foregrounds migrant precarity and adds to a small body of empirical literature that is significant in understanding the spatial and structural elements of circular migration in India and in turn, the migration crisis that emerged as a result of the economic shock of the COVID 19 pandemic.</p>","PeriodicalId":34915,"journal":{"name":"Indian Journal of Labour Economics","volume":"63 4","pages":"1143-1163"},"PeriodicalIF":1.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41027-020-00290-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38616858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has been largely through a high growth performance facilitated by significant remittances from abroad. However, there have not been consistent time-series data on annual remittances. This paper is an attempt to fulfil this gap by estimating foreign remittances to Kerala for a period of 47 years that is close to half a century.

The significance of the sizeable emigration to the labour market situation has also been highlighted. Given the fact that remittances come as household income confined to a small segment of the total households, the impact of annual remittances on income and consumption inequality has also been highlighted. The results show an increasing trend in inequality. Despite a high growth performance aided by remittances, Kerala has not been able to address its longstanding problem of educated unemployment, especially for its women.

In particular, male-specific out-migration has been a sustained tradition from the hill districts of Uttarakhand. The people have been migrating not just for seeking diverse avenues of employment, but also for accessing better educational and health opportunities. As per 2011 Census, the overall population growth rate in the state was 1.7% with huge differentials in the hill and plain districts. Hill districts witnessed one-fourth growth (0.7%) of the population compared to that of plain districts (2.8%) suggestive of huge out-migration from these (hill) districts of the state. The important thing to note is that the nature and patterns of out-migration have now paved the way from long-term to permanent out-migration. Also, the lack of employment opportunities is creating distress out-migration to destinations within or outside the state, which has become a major cause of concern. The COVID-19 pandemic has impacted the most short-term migrants who returned to their villages in desperation resulting in despondency and distress. In this context, the paper explores the factors of distress migration by analysing the data from a quick survey of 323 return migrants carried out in June 2020 to understand their employment and livelihood profile, reasons for their return to native places, coping mechanism and future plans. The findings reveal that due to lack of livelihood opportunities in their place of origin, most of them would eventually like to return to their destination places in the future to eke out their living. From a policy point of view, enhancing the economic base and livelihood opportunities by focusing on niche activities with improved provisioning of educational and health infrastructure and services can eventually help restrict out-migration from Uttarakhand.</p>","PeriodicalId":34915,"journal":{"name":"Indian Journal of Labour Economics","volume":"63 4","pages":"1107-1124"},"PeriodicalIF":1.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41027-020-00291-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38616859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unpaid work, which is the work that does not receive direct remuneration, includes unpaid work that falls within the production boundary of the System of National Account (SNA) and unpaid work that falls within the general production boundary but outside the production boundary (non-SNA). The former unpaid work is a part of the conventional economy while the latter work, on which 35–50 % of the total work time is spent by economies, is outside the national income accounts and is usually invisible in national statistical systems. This paper points out that the exclusion of unpaid non-SNA work from national accounts and from the conventional economy is not justifiable, as both works contribute to the conventional economy in several ways. The uneven distribution of unpaid work across the gender is at the root of gender inequalities and it also implies the sub-optimal use of the national labour force. In the remaining part of the paper, the linkages of the unpaid work and the economy and the different approaches of integrating unpaid work with the macro-economy are discussed. In conclusion, it is noted that implementation of these different approaches calls for a sound database (including regular production of quality time use statistics) and suitable analytical tools to analyse the data. The paper recommends that the time has come for economic analysis and policy, including macro-economics to take a wider view of the economy. Without incorporating unpaid work, it would remain partial and wrong. The time has also come for labour economics to incorporate unpaid work into the analysis of labour and employment for formulating realistic and efficient labour and employment policies.\u0000","PeriodicalId":34915,"journal":{"name":"Indian Journal of Labour Economics","volume":"58 1","pages":"1-21"},"PeriodicalIF":1.5,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68223486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
