Abstract
Purpose
The purpose of this paper is twofold, namely, to investigate if living and working abroad influences the (subjective) health of return migrants and to understand if there are any spillovers of return-migrant members onto health conditions of the family members left behind.
Design/methodology/approach
To that end, this paper uses the DoTM (Development on the Move) Migration Survey 2009, as well a propensity score matching to address selectivity on observables and IV (instrumental variables) for the selectivity on unobservables.
Findings
Results suggest that when equalized on observables, return migrants have better health than non-migrants. However, the reverse causality channel (less healthy individuals are more inclined to return) works to attenuate the true effect of return migration on health. Results further suggest a positive spillover effect of return migration on the health of the family members left behind, being mainly driven by the work of remittances sent while abroad, and not by the returned wealth or by the health knowledge transfer.
Originality/value
This paper offers at least two novelty lines to contribute to the current sparse of knowledge. First, it is among the scarce papers, and probably the only quantitative one, to investigate the nexus between return migration and health outcomes. Second, it heavily dwells on the role of selectivity (both on observables and unobservables) in determining the true (causal) effect of return migration on health.

Abstract
Purpose
The purpose of this paper is to investigate if public provision of employment support services to youth leads to reduced informality and increased wages in transition economies.
Design/methodology/approach
The author uses the school-to-work transition data sets of the International Labor Organization for seven transition economies of Southeast Europe and the Commonwealth of Independent States. The author focuses on two econometric issues: the selectivity into informal employment and the endogeneity of the public employment support service provision with respect to informal employment and wages. The authors achieves identification by employing internal regressors which are uncorrelated with the product of heteroskedastic errors, a-la Lewbel (2012), as the author could not prove the external validity of the commonly used external instruments in similar contexts.
Findings
Results suggest that the public provision of employment support services matters for relegating informal employment, but not for wages, in general. Placement in education or training programs is most powerful in reducing informal employment among the four different employment support services, while only advice for job search works positively for wages probably through enabling better match.
Social implications
Increasing budget allocations, varying the array of public employment support measures, enhanced targeting, and advancement of the profiling system may significantly contribute to strengthening the public employment support service effect on youth employment in transition economies.
Originality/value
The paper brings a couple of novelties to the current literature. First, it is among the early papers dealing with the issue of informality, public employment support service and labor market prospects of youth in general in a rigorous manner. Second, it fills an important gap for transition economies which were less researched due to the long-lasting transition process as well due to data scarcity. Third, it utilizes the recently collected School-to-Work Transition Surveys (SWTS). Finally, and likely most importantly, it thoroughly addresses the issues of selectivity bias and endogeneity of PESS by utilizing a recent approach of Lewbel (2012) whereby internally generated variables are used as instruments. Hence, the paper accounts for the endogeneity stemming from unobservables in a novel manner, contrary to the common approaches in the literature based either on propensity score matching addressing selectivity on observables only, or relying on commonly used instruments in the labor market literature – mainly regional employment variables – whose external validity is easily disputed.

Abstract
Purpose
Welding is a widely used manufacturing process in many industries. The process consumes a lot of energy and resources, pollutes the environment, and emits gases and fumes into the atmosphere that are dangerous to human health. There are various welding processes, and the suitable welding process is usually chosen based on cost, material, and conditions. Subjectivity is the most significant impediment to selecting an optimal process. As a result, it is critical to develop the appropriate set of criteria, use the best tool and methodology, and collect sufficient data. This study examines the sustainability of welding processes and their environmental impact.
Design/methodology/approach
The welding process’s sustainability was examined and discussed in general, considering the technological specifics of each welding process, physical performance, and environmental, economic, and social effects. The study investigates the environmental impact of MMAW, GMAW, and GTAW/GMAW processes through experimental work and LCA methodology.
Findings
MMAW is the most environmentally harmful technology, whereas GMAW has the least impact. The GTAW/GMAW process outperformed the other processes in terms of yield stress, but the analyses revealed that it had a greater environmental impact than GMAW.
Originality/value
The study provides an environmental impact summary and demonstrates the effects of welding parameters and processes. This gives users an understanding of choosing the best welding technique or making the process more environmentally friendly. These recommendations help policymakers identify hot spots and implement the right plans to achieve more sustainable manufacturing.
