As inter-sectoral linkages are being increasingly organized in complex networks, It has become inconceivable to study sectors’ responses to exogenous shocks without considering the nature of these invisible but real linkages Leontief (1941). However, although important, this research field remains poorly analyzed in both the theoretical and empirical literature. In this paper, we aim to investigate how sectors’ network centrality and local density measures impact their responsiveness to sectoral shocks propagating through input output linkages.

COVID-19 pandemic caused significant disruption of trade flows between countries, revealing the vulnerability of global value chains. This unexpected event sparked a public debate on devising new policies to increase the resilience of value chains. This study identifies vulnerabilities related to supply chains with a specific focus on Tunisian imports during the period 2019-2020. To this end, we select three potential drivers of import vulnerability based on post-pandemic reports and discussions and assess their impact on Tunisia’s overall imports using quantitative analysis.

Voluntary supply chain regulation has proliferated in recent decades in response to concerns about the social and environmental impacts of global production and trade. Yet the capacity of supply chain regulation to influence production practices on the ground has been persistently questioned.
