Abstract
Aim and Introduction: 
Vulnerable employment, a segment of the informal economy, includes home-based businesses that emerge due to a lack of opportunities for formal employment. These businesses often operate without essential benefits such as medical insurance, social security, bonuses, and pensions, which exposes workers to economic instability. Consequently, many individuals engaged in vulnerable employment seek loans and financial assistance to expand their business activities and transition to the formal sector. Banks, as the primary providers of such loans, request collateral from borrowers – typically in the form of property documents – to ensure repayment and mitigate financial risk. Strengthening legal rights related to loan collateral enhances banks’ confidence in issuing loans, thereby increasing access to credit for vulnerable workers.
Due to the oil-dependent nature of OPEC economies and their reliance on oil revenues, many of these countries often lack robust production infrastructures capable of generating sufficient formal employment opportunities. This study aims to analyze the effect of strengthening loan-related legal rights on vulnerable employment in OPEC member countries, including Iran, Iraq, Algeria, Angola, Congo, Gabon, Kuwait, Saudi Arabia, the United Arab Emirates, Venezuela, Guinea, Libya, and Nigeria, during the period from 2013 to 2021.
Methodology: 
Following the approach of Herkenhoff et al. (2021), this study employs a model in which the independent variables include the strength of legal rights related to loans, oil revenues, secondary school enrollment rates, and the urbanization ratio. Given the study’s objective of analyzing the threshold effects of legal loan rights on vulnerable employment, the Panel Smooth Transition Regression (PSTR[A1] ) method is used to estimate the model.
Results and Discussion: 
The analysis identifies a 6.22% threshold in the legal rights index, distinguishing two distinct regimes. In the first regime, the strength of legal loan rights does not significantly impact vulnerable employment. However, in the second regime, a higher index value reduces vulnerable employment, suggesting that more substantial legal loan rights facilitate the transition of workers from the vulnerable to the formal sector. Additionally, oil revenues and secondary school enrollment rates exhibit a negative effect on vulnerable employment, while the urbanization ratio has a positive effect.
Conclusion:
The findings of this study indicate that strengthening legal loan rights has contributed to a reduction in vulnerable employment, which is a subset of informal employment. This shift has contributed to growth in formal sector employment.  Banking regulations and enhanced requirements for obtaining collateral have increased banks’ confidence in lending, as they are better able to mitigate the risk of non-repayment. However, this system primarily benefits individuals who can pledge valid collateral, such as real estate and housing documents. Given the high value of such collateralized assets, borrowers are more likely to invest their loans in business development, transitioning their employment from the informal to the formal sector. In addition to securing stable employment, they also gain access to social benefits such as insurance and social security. This financial stability enables them to make timely loan repayments, preventing defaults and preserving their financial credibility.
Based on these findings, it is recommended that governments and banking authorities in the investigated countries implement strict laws and regulations to guarantee loan security and identify factors contributing to bank insolvency. Such measures would help prevent financial resource mismanagement in the banking sector and reduce the probability of bank failures. Strengthening financial regulations and risk management strategies would facilitate lending, ultimately promoting employment growth in the formal sector and reducing the prevalence of vulnerable employment.
Furthermore, the study reveals that oil revenues negatively impact vulnerable employment, which may be attributed to increased government spending on productive investments and formal job creation. This suggests that redirecting oil revenues toward investment, production, and employment generation—rather than short-term expenditures—can facilitate the transition of workers from the informal to the formal sector. Thus, policymakers are encouraged to prioritize long-term economic strategies that allocate oil revenues to sectors that foster sustainable employment opportunities.
The findings also highlight the positive effect of education on labor force transition. Higher levels of education and training result in a more skilled workforce, increasing their acceptance and employability in formal job markets. Therefore, governments should allocate additional resources to public education, provide free schooling, and expand access to higher education for economically disadvantaged groups. Promoting scientific education and fostering a culture that values learning can further enhance workforce skills and economic mobility.
Finally, the study finds that urbanization has had a positive effect on vulnerable employment, indicating that increasing urbanization has not been accompanied by industrial advancements or skill development, thereby failing to support the expansion of the formal sector. Instead, urbanization in the studied countries has often been driven by unfavorable business environments, weak regulatory frameworks, and a lack of political transparency, contributing to the growth of the informal economy. To address these challenges, policymakers should focus on improving governance, strengthening legal and economic structures, and fostering a business-friendly environment that supports formal employment.
