This paper analyses the informal channels of the job search process through migrant networks in the urban labour markets in developing countries. Using a novel approach and nationwide sample survey, we measure various aspects of migrant networks such as size, diversity, efficiency and experience content and estimate their effect on probability of employment. Our findings suggest that migrant stock (having experience content) has an inverted-U relationship with the probability of finding a job for a migrant. The share of employed workers in a migrant network (efficiency) and different origin identity (diversity) positively affect the employment outcome through weak ties. Further, the migrant network effect is more active in larger cities as compared to smaller urban areas. The implications of this study indicate towards the importance of non-market informal channels in job searches and the need for integrating labour markets to harness the benefits of larger positive network externalities.  相似文献

In the midst of a genetic revolution in medicine, Assisted Reproductive Technology (ART) has become a well‐established technique to help infertile women achieve pregnancy. But many women are now turning to ART not just to circumvent infertility, but consciously to shape their families by determining the sex of their children. Many patriarchal cultures have a gender preference for males and to date have used technological advances in reproductive medicine to predetermine the sex of the child being born. Women have sought sex‐selective abortions, where the pregnancy was being terminated solely on the basis of the sex of the unborn fetus. The combination of ART advances and gender preference has led to the disappearance of at least 100 million girls from the world's population leading to a mass gendercide. This article examines the societal impact of unbalanced gender ratios and the need to regulate sex selection to avoid nations of bachelors.  相似文献

This article examines the microeconometric evidence on the impact of government support for R&D and innovation. Our meta‐regression analysis uses a dataset of empirical evidence on the effects of government R&D policies on innovation and investigates the factors that may explain the differences in the estimated effects. The meta‐analysis is structured to include both the direct and indirect government support for R&D and innovation. The estimated results reveal the heterogeneity of empirical studies with respect to the type of incentive, data, and econometric methodology used. The results indicate that the output additionality effect is on average stronger for R&D tax incentives than subsidies. Studies that use the subsample of high technology sector show a stronger additionality effect of fiscal incentives on innovation. Moreover, small and medium enterprises have a stronger input additionality effect. The results also suggest that studies considered endogeneity issues have on average stronger additionality effect.  相似文献

ABSTRACT

Despite the extensive literature on distributive politics, there is still is a lack of a theory of how political and fiscal institutions interact to shape the pork barreling ability of national leaders in a federal parliamentary democracy. This article examines how the party system types (dominant party versus coalition system) and particular attributes of discretionary grants (providing credit claiming opportunity or facilitating side payments) influence opportunities for pork-barrel politics. This article proposes a situational theory of distributive politics that states that incentives for exclusive targeting of affiliated states in one-party dominant systems drive national ruling parties toward particularism while the shrinking opportunity to indulge in such a policy in multiparty coalition systems creates a universalization effect. The disaggregated analysis of discretionary grants using Indian data for 14 states for the one-party dominant period (1972–89) and the coalition era (1996–2012) confirms the theoretical expectations. Additionally, the exercise brings to the fore the fact that the shift from particularism to universalism occurs for schematic grants that provide credit claiming opportunity. The ad hoc grants that are like side payments remain subject to particularism.  相似文献
